Field to Gin Cotton Handling and Storge Systems

1. The Field of the Invention

The fields of art to which this invention pertains are seed cotton forming, loading and transport and pre-ginning treatment and apparatus therefor.

2. Description of the Prior Art

The prior are has suffered with economically inefficient transportation of field cotton at low bulk density and, where high bulk density has been used, from mechanical difficulties in ginning the product, especially where large amounts of trash are collected by machine picking.

By this invention, a practical and efficient system of compression for storage and economically as well as mechanically efficient transportation is combined with a pre-ginning treatment that provides a cotton of improved ginning characteristics.

The apparatuses and process steps of this invention provide a complete field to gin cotton handling and storage system comprising the sequence of steps of: (a) gathering and compression of harvested cotton to form a module thereof of 12 to 14 pounds per cubic foot density; (b) storage and transport of the cotton module on a pallet particularly adapted for use in the apparatus wherein the compression is applied to such cotton for its transport as well as storage and other handling in an apparatus to break the module; (c) after storage and transport, the module mass on the pallet being handling to so be broken into variable lengths of high but limited bulk density and then being so held and moved so as to provide a self-regulating feed density to a threshing zone whereas the cotton bolls and trash are automatically separated and the bulk density of the cotton is reduced to 2 to 3 pounds per cubic foot; and (d) the thus produced low density mass of intermixed cotton and trash being passed to a pneumatic separator at the gin whereas the thus produced low bulk density cotton is separated from trash, twigs and like refuse gathered during normal mechanical cotton picking.

In the preferred embodiment, dimensions of the apparatus 30 are as set out in Table I.

In general, the apparatus for the overall system shown in FIG. 20 comprises a mobile press assembly 421, a pallet assembly 450, a loaded pallet assembly 590, a tilt bed trailer 570, and a module treating assembly 30. The combination of units operates as an overall system to effectively transport and treat field cotton.

The mobile press assembly 421 is structured to load a pallet with a mass of vertically compressed seed cotton at a uniform density without development of horizontal or lateral compressive stress as might, after removal of the loaded pallet from the mobile press, result in extrusions of the compressed seed cotton. The pallet, while light enough to be handled by manual labor, is formed to provide such limited bowing that no compression is developed in the mass thereon as results in permanent disruption of the even interior density and surface of the loaded mass during movement of the loaded pallet to and from a tilt bed trailer transport therefor, transport on the trailer, and storage in the field or at the gin yard.

The pallet for this purpose comprises an imperforate water-impermeable transversely grooved thin corrugated sheet and a plurality of parallel longitudinally extending like runners, each runner composed of two like vertical extending outwardly sloped side walls and a bottom flat smooth horizontal sheet, the side walls firmly yet resiliently joined at corners along the total length of their bottom edges to the total length of the left edge and right edges, respectively, of the bottom sheet and extending upwardly therefrom and the sheet is firmly connected to the top of the side walls at regularly longitudinally spaced apart points at greater distances than the points of contact of said sheet and said runners and the height of the sheet varies in periodic and uniform continuous manner from lowest points to highest points, and intermediate portions of the sheet extend vertically therebetween and are continuous therewith and provide support for its horizonally extending portions.

The apparatus 30 for treating the high density storage stable transportable module to form readily ginned mass of low density cotton comprises a feeder compartment to a dispersing element whereat the trash and cotton bolls are separated. The feeder compartment receives a large module of mechanically harvested cotton on a movable loading frame, the loading frame empties into that compartment from an elongated side of that feeder compartment and thereby provides for a particularly rapid and efficient unloading of the transport apparatus of the system; such unloading is accomplished by a lift door assembly, including an apron movably located within that lift door assembly and below the upper surface of the movable loading frame on which the module is loaded; this combination of movable loading frame and apron provides for adjustable lateral location of the movable loading frame for acceptance of the transport pallet on the upper surface of the lift door assembly. The lift door has a clamping assembly with which to hold the pallet and the cotton module located whereon for movement of that high density module into the feeder compartment. Such module movement into the feeder compartment is accomplished in a manner to break the module into small masses of lower bulk density in said feeder compartment. The belt conveyor on which the broken module is fed permits the broken cotton module mass to slide thereon and releasably, yet efficiently, feeds the mass to the dispersing elements. The dispersing elements have a large but uniform orifice through which to pass cotton bolls and trash when separated from each other and the dispersing units provides a sufficiently high energy input to handle the reduction in bulk density of the fed mass (of 12 to 14 pounds per cubic foot to 2 to 3 pounds per cubic foot in the product at a rate of 30 bales per hour). The belt cooperates with the apparatus frame to confine the mass of harvested cotton and trash and provides a gradually increasing bulk density through the relatively elastic mass of cotton thereby developed to provide a substantially constant rate of feed to the dispersing elements whereby a low density detrashed cotton product is made and a uniform action thereon is provided. The trash and cotton then are separated by an air separator, with the thus purified cotton passed to a gin whereat the thrashing action provided by the dispersing units is reflected in the improved ginning characteristics of the product.

The disrupting assembly 41 is also hereinbelow referred to as the dispersing assembly because it disperses the components of the mass 139 presented thereto by the belt 147 in the module treating assembly 30.

The picked cotton treated by the apparatus 421 to produce a bulk density of between 10 and 15 pounds (preferably 12 to 14 pounds) per cubic foot and in that condition of density stored on pallet 450 and later transported to the module treating assembly 30 has a density of 2 pounds per cubic foot when it comes through the dispersing unit 41 while strip cotton has a density of 21/4 pounds to 21/2 pounds per cubic foot when correspondingly treated.

The mobile press assembly 421 comprises a plunger subassembly 422, a container sub-assembly 423, and a tractor 424. The mobile press assembly comprises the plunger subassembly 422 supported on the container subassembly 423; assembly 423 is attached to and drawn by the tractor 424. The container subassembly comprises a plurality of rigid vertical walls 431-4, i.e. a front wall 431, a left side wall 432, a right side wall 433 and a movable rear wall 434. Lateral to each of the left and right walls are rotatable wheels as 425 and 425', with vertically adjustable wheel supports as 426 and 426' which are firmly attached to walls 432 and 433 provided with wheel support lifting means 427 and 427'. A power supply 440 comprising a hydraulic pump and high pressure reservoir is connected to each such wheel support lift means.

The walls 431-4 enclose a container chamber 430 open at its top. The power supply box 440 is fed by hydraulic input power lines 440' from tractor 424 and is connected by lines as 439 to the wheel support lift means 427 and 427' so that the container subassembly will be elevated over the ground by such wheels during transport of that container subassembly while drawn by the tractor 424. Container chamber 430 is wider at its bottom than at its top and has the same width at its top from front to rear of the walls 432 and 433 and has the same width at its bottom from front wall 431 to rear wall 434.

Such a mobile press assembly is generally shown in U.S. Pat. No. 3,749,003; although the mobile press assembly 21 herein is different from that described in such U.S. Pat. No. 3,749,003 in regard to the tamping or plunger subassembly 422 and the method of aligning the empty pallet by virtue of the use of the winch 441 and cable 442 on the container subassembly.

The lifting means 427 and 427' comprise means for controllably moving the wheels 425 and 425' relative to the walls 431-434. Such means include hydraulic piston cylinders 600 and 601 which are supported on horizontal frame members as 602 and 603 and hydraulic actuation means therefor. The members as 602 and 603 are supported on rigid vertical side wall frame members as 604 and 605 and 606. Each piston shaft as 608 is movable in a cylinder as 200 and 201 attached to wheel supports 426 and 426'; actuation of the hydraulic pistons movement of the shaft moves the wheel relative to the walls 431-434.

A winch 441 is supported on the front wall 431 of the container subassembly has a cable 442 wound thereon. The cable 442 passes through a top guide 443 to a bottom guide 444 around cable wheels as 445 through guide 444 whereby to be operatively connected to and act upon the guide 450 generally as shown in FIG. 4.

The loaded pallet assembly or module 590 is transported by lifting to and movement on a tilt bed trailer as shown in FIG. 3. Tilt bed trailer 570 comprises a bed 571 and a set of wheels 572. The trailer bed 571 is a rigid flat topped frame of rectangular shape as seen from above with a pointed straight rear end 575 and a straight front end 576 the front end firmly supports a hitch 577 for connection to hitch 428A of tractor 424; a bed winch 573 is mounted on the head end or front end 576 of the bed 571 to move the loaded pallet assembly on the bed 571, as shown in FIG. 3. The rear bed end 575 terminates in a pointed nose or end. Such a trailer is shown in U.S. Pat. Nos. 2,487,325 and 2,452,681.

The loaded pallet assembly 590 comprises a pallet 450, cables as 591 and 591', a tarpaulin 592 with grommets as 593 hooks as 595 and a cotton mass 597. The mass 597 of cotton bolls is a uniformly compressed mass of 12 to 14 pounds per cubic foot density and its top is covered by a heavy duck waterproof tarpaulin 592, provided with grommets as 593 near its sides; each cable as 591 extends through the eyes of the tarpaulin (eight on each side of the tarpaulin, evenly spaced along as a 24 foot length, although only four are shown in FIG. 3) and the eyes as 644 of hooks as 595. The hooks as 595 (and like hooks as 481-485) are firmly connected to the pallet 450.

A conventional power take off on tractor 424 drives a pump 440C that is supported on frame of tractor 424 and operatively connected to power lines as 440' to power supply box 440 and contact valves as 446 and 440A (FIG. 10) for movement of the container subasembly 423 and the plunger subassembly 422. Mass 597 is 8 feet high, crowned higher in its middle than at its sides and ends. Pallet 650 operates as does pallet 450 in assembly 590. The structure of pallet 650 and 450 differs only in the structure of the runners (451-454 for pallet 450, 651-654 for pallet 650).

The tamping or plunger subassembly 422 is movably yet firmly supported on top of and is movable longitudinally of the container subassembly 423. The plunger subassembly comprises a plunger shaft 435, a tamping or plunger head 436 a plunger cylinder 437, a transverse plunger support 438 and a left and right plunger support guide 489 and 489'. The plunger support 438 is a rigid transversely extending frame composed of front and rear transverse frame members 438A and 438B firmly joined together (see FIGS. 6 and 8). The frame has side wheels 438C and 438D and 438F movably supported on the rigid horizontal head guides 489 and 489' on top of the walls as 432 and 433 of the container subassembly 423. Cables 439B and 439C attach to and move the frame 438 longitudinally of the walls 432 and 433.

A rigid plunger cylinder 437 is supported on frame 438 and extends upward vertically in its opertive position, as shown in FIGS. 1 and 5; a plunger shaft 435 is slidably located in cylinder 437 for movement upward or downward, as determined by a press control valve 446. The bottom end of plunger shaft 435 is firmly attached to the head 436 whereby on activation of the shaft, the flat transversely extending head 436 whereby on activation of may compress material as 578 held within the container chamber 430.

Head 436 is a rigid horizontally extending flat bottomed plate that extends horizontally slightly less than the width of the top of container chamber 430.

The plunger assembly 422 comprises units therein that specifically provides for maintaining the plunger head 436 level during tamping and leveling the mass of cotton in chamber 430 while operating quietly and without depositing grease on the mass of cotton tamped therewith, and in a reliable manner without requiring maintenance over long periods of operation.

More particularly, the tranverse rigid frame 438 supports a plurality of chain supporting guide sprocket wheels 511-514, i.e, rear right chain guide sprocket wheel 511 and front right chain guide sprocket wheel 512 are rotatably supported on an rigid axle 420 while the corresponding front left chain guide sprocket wheel 513 and rear left chain guide sprocket wheel 514 are supported on a right inner axle 510. Each axle as 510 also supports an inner left guide roller 526 while an outer guide roller 526 is supported lateral to the left guide post 517 on a left outer axle 519 (FIG. 6).

A flexible left top control chain 515 extends from an upper bracket 537 firmly attached to top of the left post 517 via an adjustment rod 539 with a nut 534 thereon (as in FIG. 7 and FIG. 6) to engage teeth on the bottom and outer side of the guide sprocket wheel 514 and, thence to the top teeth of sprocket guide wheel 511 to attach to a bracket 535 at the bottom of the vertical right post 518 near the junction of that right post to the head 436 as diagrammatically shown in FIG. 10. Adjustment rod 539 has a nut 534 thereon and a spring or lock nut 533 thereunder and provides for tightening of the chain 515.

The middle portion of a flexible right top chain 516 identical in structure and size to chain 515 extends over and engages teeth at the top of left side guide wheel sprocket 513 and extends to and engages the bottom teeth of sprocket guide wheel 512.

The lower end of the left chain 516 is attached to a bracket 536 on the left side of head 536 near the bottom end of post 517. The top end of the right chain 516 extends to an adjustment rod like 539 with a spring support nut like 534 on a bracket 538 on top of the vertical post 518 like bracket 537 on post 517.

The chains 515 and 516 are flexible but dimensionally stable and their attachments to the vertical guides 517 and 518 and head 436 provide that an actuation of the piston shaft 435 in cylinder 437 the bottom face of the plunger head 436 is maintained level or horizontal on its upward and downward motions and on compression of the material as 578 in the container chamber 430 due to the movement of that head against such material and toward the pallet 450 therebelow.

A three-way valve 446 under control of an operator as 500, applies hydraulic fluid to the piston 447 top or bottom to move the shaft 435 (attached to the piston 447 at its top and head 436 at its bottom) and head 436 down and up to tamp the cotton 587 in chamber 430. The valve 446 may also position the head 436 at a fixed vertical height, whereat the head 436 is moved longitudinally along length of chamber 430 on guides 489 and 489' while driven by motor 439A through chains 439B and 439C which chains are attached to frame 438 (see FIGS. 5 and 10) to even out or level the top of the mass of cotton bolls in chamber 430 prior to tamping.

The combination of posts as 517 and 518 vertically movable on rotary guides 525 and 526 for each post, chains as 515 and 516, wheels 511-514 and hydraulic piston of subassembly 422 provides a reciprocatory mechanism to tamp and capable also of exact location to level out the cotton in chamber 430. Because the exposed surfaces of posts 517 and 518 and wheels as 525 and 526 are guide surfaces rather than driving and driven surfaces, such action of the subassembly 422 is accomplished without such an application of grease to surfaces on moving parts of subassembly 422 as would effect the surface characteristics of the mass of harvested cotton bolls 587 located in chamber 430. The reciprocation of the head 436 of subassembly 422 is thereby accomplished quietly so that the operator 500 may manipulate the plunger or tamping subassembly 422 while in voice contact with the operator 555 of a harvester 550 dumping cotton into chamber 430 as shown in FIG. 1. Further, the subassembly 422 is free of shocks (present in usual mechanical gear devices) that cause high wear rates and mechanical failure at inopportune times when cotton is dumped into the container chamber 430 over its top, as shown in FIG. 1, from a harvester 550; the mass 578 in chamber 430 initially has a pyramidal shape with narrow top and may be asymmetrical to front or rear or to one side or the other; notwithstanding the usual asymmetry of such load to which the press head 436 is applied, the subassembly 422 provides a vertical compression of such mass 587 in chamber 430 without any lateral component of stress applied by that press head.

Cylinder 437 is supported near its bottom in clamp 553 and 554 and is attached at its bottom to a rigid plate 522. Plate 522 is supported on movable rods 523 and 523A thereabove in frame 438. Rods 523 and 523A are located in a slot 523C on top of a rigid ell 523D in plate 438A of frame 438 and on a similar slot and ell 523E in plate 438B of frame 438. This compression provides for a stable mass or bale on top of the pallet 450 when the module formation, according to this process of operation of this apparatus, is completed.

The mounting of the cylinder 437 thus provides for release of the support plate 522 by removing the support rods 523 and 523A (which are locked into place on ell 523D by the nuts 524 and 524A). The cylinder 437 may then move downward through the slot 438C between frame members moved downward from position shown in FIGS. 1 and 5 for transport purposes without any further disassembly. When operational assembly of portable press assembly 421 is desired, the piston cylinder 437 is moved up on shaft 435 by actuation of the hydraulic liquid pressure in cylinder 437 until the plate 522 is in position as in FIG. 8 whereat the support rods 523 and 523A may be located in the plates 438A and 438B.

The action of plate 436 of plunger assembly 422 avoids any development of horizontal or lateral compressive stress as might, after removal of the loaded pallet 590 from the restraining action of walls 433 and 432 (and 431 and 434) result in extrusion of portions of the mass 597: the tarpaulin has no direct influence on lateral escape of the compressed mass 597.

The pallet 450 comprises an imperforate water impermeable transversely grooved surface formed of a thin corrugated imperforate steel sheet 455 and a plurality of parallel longitudinally extending runners 451, 452, 453, and 454. Each runner as 451 is composed of a left vertically extending yet outwardly sloped left side wall 461, a bottom flat smooth horizontal sheet 462, a right vertically extending outwardly sloped side wall 463, a top left flange 464, a top right flange 465, a rounded front left end plate 466, a front right end plate 467, a rear left end plate 476, a rear right end plate 477. The left side 461 and the right side 463 are firmly yet resiliently joined at softly rounded (3/16 inch radius) corners as 461R and 463R along the total length of their bottom edges to the total length of the left edge and right edges, respectively, of the bottom sheet 462. The sheets 461, 462, 463, and flanges 464 and 465 are formed of thin medium carbon sheet steel (0.05 inch thick) resilient yet springy and formed by cold drawing a plate of such material.

The upper end of each of sides 463 and 461 are joined by corresponding soft rounded corners 464R and 465R to flanges 464 and 465, respectively.

The left side edge joins at its front end a rigid metal front left plate 466 with a hole 468 therein while the right side 463 is joined to a rigid front right plate 467 with circular hole 469 therein. The left side joins a rigid rear left plate 476; the right plate joins a rear right end plate 477 with holes 478 and 479, respectively, therein. These holes 478 and 479 in member 476 and 477 and the like holes 468 and 469 in members 466 and 467 locate a rigid cylindrical drawbar 470 at the front end and a rear drawbar 472 at the rear end.

Corresponding structures in runners 452, 453 and 454 are indicated by referent letters A, B and C, respectively; thus, bottom surface 462, 462A, 462B and 462C are the same structure in each of runners 451, 452, 453 and 454, respectively, and end plates 467, 467A, 467B and 467C are similarly formed and similarly function as herein described.

The sheet 455 is an imperforate galvanized corrugated steel sheet with a plurality of like, parallel transversely extending upwardly convex grooves as 456A and downwardly convex portions 456B thereon forming generally a sine curve. Such shape is diagrammatically shown in FIGS. 17 and 18. The top of flanges as 464 and 465 of each of the runners as 451 are firmly joined to the bottom surface of the sheet 455 at portions of such sheet, as 621 and 623 that are spaced apart from each other by greater distances than the points of contact of the sinusoidal curved sheet and the flanges 464 and 465.

As seen in longitudinal cross section, as diagrammatically shown in FIG. 17, sheet 455 is of sinusoidal shape: the lowest points on the lower surface of such surface as points 560, 562, 561, 563, 564, 565 (in FIG. 18), 567 (in FIG. 16), 456B (in FIG. 17) are in contact with the top surface of flanges as 464 and 465 (and 464A, 464B, 464C and 465A, 465B and 465C). The high points as 661-663 (in FIG. 18), 569 (in FIG. 16), 456A (in FIG. 17) are 7/8 inch above the lowest points neighboring thereto and the lowest points -- like the highest points -- are 21/2 inch distant from each other; sheet 455 is 1/20 inch thick (26 gauge). The height of sheet 455 over flanges 464 and 465 varies in periodic and uniform continuous manner from lowest points as 560-565 to highest points as 661-664 on the sheet 455. The intermediate portions of the sheet, i.e. the portions (as 668 of FIG. 16) of the sheet 455 between the highest and lowest points as 667 and 669 of sheet 455 extend vertically therebetween and are continuous therewith. Each such portion as 668 is continuous with and provides a ribbing or support action for the horizontal portions, as the generally horizontal top sheet portion 669 near each top point as 569 in FIG. 16 of the sheet 455 and the relatively horizontal bottom portion 667 near the bottom point, as 567 of FIG. 16, of sheet 455.

The point of joining of the flanges 464 and 465 on each runner as 451 to the bottom surface of sheet 455 are abreast of each other, as shown for points of joining 560 on flange 465 and 560' on flange 463 and also for points 561 and 561' on flanges 465 and 464, respectively. The points of attachment of the flanges of runners 451, 452, 453 and 454, all the runners of pallet 450, to the bottom surface of sheet 455 are also abreast of each other, as shown in FIG. 11 -- i.e., at equal distances from the front drawbar 472 and the straight front edge 503 of sheet 455 -- for the illustrative attachment points 560, 560' on runner 451, points 560A and 560A' on flanges 464A and 465A of runner 452, points 560B and 560B' on flanges of runner 453, and points 560C and 560C' on flanges of runner 454 while points 561, 561', 561A, 561A', 561B' , 561B, 561C' and 561C are also at equal distances from 472 or abreast of each other, as also shown in FIG. 11.

Each of the end plates 466 and 467, 476 and 477 on runner 451 is like the front left plate 466 of runner 451; plate 466 comprises a rigid rectangular base solid portion 540 and a rounded trapezoidal extension member 541 formed of 1/8 inch thick steel plate. Left plate 467 comprises a corresponding base 542 of same thickness, size and shape and material as portion 540 and rounded trapezoidal extension plate 543 of same size, material, shape and thickness as 542. Each rectangular base portion as 540 and 542 is firmly attached to one side wall as 461 and 463 of the runner as 451.

The lower edge as 545 of each plate 467 lies in a plane 546 which forms a small acute angle as 547 with the horizontal plane 548 in which the lower surface of the bottom plate portion as 462 of the corresponding runner 451 lies, the intersection of planes 546 and 548 and the angle 547 are located in front of front edge 506 of bottom plate 463 of runner 451. This small acute angle 547 is a lesser angle (with such surface 548) than the angle 551 between the ground surface 552 and the top bed surface 574 at the rear end 575 of the tilting bed 571 of the tilt bed trailer 570 used to lift and transport the pallet 450 with the load of cotton 597 thereon, as shown in FIGS. 3 and 18. The bottom surface or 462, 462A, 462B, 462C of each runner as 451, 452, 453 and 454, respectively, is in contact with and may, for all practical purposes, be regarded as co-planar with the top surface 552 of the ground when the pallet is being loaded with cotton, as shown in FIG. 2. Each of the rear end plates as 476, 477 is rigid and firm and is firmly attached to rear of runner side plate as 463 and 461, respectively, as above described for plates 466 and 467. Correspondingly (to the structure of runner 451), each of rear runner end plates 476A, 476B and 476C and 477A, 477B and 477C are firmly attached to rear end of a runner side plate as 461A, 461B, and 461C and 463A, 463B and 463C. While the side plates 461 and 463 of each runner as 451 (and 452-4) are somewhat flexibly yet permanently attached to the bottom plate thereof, as 462 the welded longitudinally spaced apart attachment of the upper plates 464 and 465 to the bottom surface of layer 455 provides a sufficiently firm location and orientation of the bottom edges as 545 of each end plate as 466 (and 467) that the contact of such sloped bottom edges of the forwardly and upwardly extending portions of arms as 466A and 467A on runner 452 and 466B and 467B on runner 453 and 466C and 467C on runner 454 and pulling of rod 472 toward bed winch 573 in position of parts as shown in FIGS. 3 and 18, lifts the front edge as 503 of sheet 455 and the front edge, as 506 of each bottom plate as 462, 462A, 462B and 462C of each runner as 451, 452, 453 and 454 respectively, onto the nose of the rear end 575 of the tilting bed 571 of the bed trailer 570 as shown in FIGS. 3 and 18.

Accordingly, each runner as 451 54 is rigid at its front and rear end for lifting the loaded pallet assembly 590 onto the trailer 570 yet is sufficiently flexible and resilient at its other portions therebetween, as shown in FIGS. 18 and 18A and 19C and 19D, to avoid development of localized zones of high compressive stress as may provide for distortion or shifting of the load pallet assembly 590.

A pallet 450 made of only such light 26 gauge sheet 455 (about 1/32 inch thick) is adequate to carry 15,000 pounds of cotton as 597 on a pallet 455 that is 7 feet 6 inches wide and 24 feet long compressed to a pressure of about 15 pounds per squre inch and having a density of 12 to 14 pounds per cubic foot. Sheets 455 and 655 are each formed of mild sheet, type A.S.T.M.A.-446-67, Grade E, with G-90 coating and has a minimum of 80,000 p.s.i. tensile strength; runners 451-54 and 651-654 are also mild steel type A.S. T.M.A.-455, Grade D, 50,000 p.s.i. minimum tensile strength. Such a 7 foot 6 inch by 24 foot pallet weighs only 400 pounds, although pallet size ranges from 7 to 8 feet wide and 24 to 32 feet length.

A rigid front drawbar 472 passes through holes 468, 469, and like holes in runners 452, 453 and 454, the resilient hold of these plates 541 and 543 including such holes on the portion of the bar 472 adjacent such holes provides a firm grip thereon.

A towbar 630 comprising a rigid plate 631, a left J-shaped hook 633 and a right J-shaped hook 632 is used to draw the pallet 450 into chamber 430 and upwards of trailer bed 574. The towbar hook 633 releasably yet firmly engages bar 472 between end plates 467A and 466A and hook 632 releasably yet firmly engages bar 472 between end plates 467B and 466B, as shown in FIG. 13, where an operator's hand 500A is shown supporting such towbar; the plate 631 is a rigid steel plate with an eye 634 therein for attachment to cable as 568 and 442.

In operation wheels 425 and wheel support means therefor operatively attached to the walls 432 and 433 are adjusted for movement of assembly 421 about the area at which cotton is harvested and drawn to such areas by the tractor as 424. A towbar 630 is then attached to drawbar 472 and cable 442. The winch 441 is then actuated by an operator as 500 to draw the pallet 450 into the container chamber 430 and locate it between the walls 431-4 of chamber 430, as shown in FIG. 4. The upper pallet surface is then normal to the vertical path of the plunger 436. The plunger assembly 422 is also movable from front to rear (and vice versa) of chamber 430 and relative to the pallet so that the plunger 436 can act on different portions of the material as 578 added to chamber 430, as shown in FIG. 1 and then supported on different portions of the pallet 450 to even out and compress different portions of such masses supported on that pallet.

On addition of the mass of harvested cotton 578 from harvester 550 to the container chamber 430, the plunger assembly 422 is controlled by the operator 500 to drive the plunger head 436 thereof against the top mass of cotton (as in FIG. 20) above the pallet 450 and so form a mass of uniformly compressed cotton 597 of 12 to 14 pounds per cubic foot density.

The tarpaulin 592 is applied to the top surface of mass 597 to cover that mass above the pallet and protects it from rain while the continuous water impermeable surface 455 of the pallet 450 prevents moisture from entering the base of such mass 597 on the loaded pallet. The container walls 431-434 are then raised upward of the mass of cotton 597 within the container chamber 430 as by the wheel support assembly 427 as in U.S. Pat. No. 3,749,003 or other patents, as U.S. Pat. No. 2,782,586, wherein a mobile press is used, and the rear door 434 removed or raised. The mobile press is then moved away from the pallet 450 thereby leaving the cotton on the pallet 450. The cables as 591 are earlier passed through the grommets as 593 for rapid attachment to the plate edges 448 and 449.

Ell-shaped steel bars 448 and 449 are firmly attached to sheet 455 at its edges 473 and 474 and provide seating of points 641 and arms as 442 for each of hooks as 481, 482, 483, 484 and 595 on the right side and like hooks as 595 on the left side of assembly 590. Each of these hooks as 595 is formed of a J-shaped hook and a circular loop or eye. The hook is formed of an arm 642, with a bend 643 and a shaft 645 connected to the eye 644. The end 641 of arm 642 engages the side of the L-shaped side member 448 and eye 644 holds a length of rope as 591 on the other end of hook 595. The tarpaulin 592 has the eyes of grommets as 593 thereof joined to the lengths of rope 591 and weights 598 and 599 provide for a resilient tensioning of the thus covered assembly 590.

The pallet 450 thus loaded is moved up a ramp 574 of the transporter-loader assembly 570 for transport to a gin whereat the cotton added to the container chamber 430 (by a harvester as 550, as shown in FIG. 1) is to be treated. The loaded pallet is moved down the ramp at the gin and, after some storage at the gin, the loaded assembly 590 with the pallet 450 is again moved up another ramp as 574 to another treating platform as 434 at the gin. Following the removal of the cotton from the pallet 450, each pallet as 450 is stacked and, following such stacking, is returned to the grower for further use in the process of forming loaded pallet assemblies as 590, shown in FIG. 1, as herein described in relation to the action shown in FIGS. 1, 2 and 20. Accordingly, each pallet at 450 is subjected to several dragging motions in each full cycle of use thereof.

The drawbar 472 of the pallet 450 provides for applying a uniform longitudinal stress to the runners 451-4 by cable 568 of trailer 570. These longitudinal runners are flexible upwardly, i.e. transversely to the length of such runners, to provide for movement of the loaded pallet up the loading trailer 570 without damage to the cotton mass as well as to the pallet due to such repeated flexing. The pallet 450 bottom surface is straight, as viewed transversely to its direction of movement, when the combination of module and cotton thereon is drawn to the ramp 574 because the drawbar 472 is rigid and firmly draws on the runner members 451, 452, 453 and 454 and the corrugations of the sheet 455 provide rigidity against bowing or bending about a vertical axis transverse to the direction of movement of the mass 597. The corrugations also serve to engage with the mass of cotton 597 pressed thereon, and so assists in movement of the mass up the ramp. The engagement of mass 597 with the corrugations also provides for stability of such mass 597 of assembly 590 during its transport, after loading as in FIG. 19E, from the ground surface 552 of the field from which such seed cotton 597 is harvested to the gin, where such seed cotton is to be treated.

The runners 451-454 distribute the longitudinal stress of drawing the mass 597 up the ramp of the transport and loading apparatus 570 from the bar 472 to the separate portions of the sheet 455 without sheet 455 bearing any substantial longitudinal stress. Due to the transmission of such lengthwise or longitudinal stress along the runners 451-454 and the method of attachment of such runners to sheet 455 in pallet 450, pallet 450 provides for ready and controlled binding of each of its increments as the mass of the loaded pallet assembly 590 is drawn upwards of the transport loading apparatus 570.

More particularly, the sloped side walls 461 and 463 of each runner as 451 are able to bend laterally from positions shown in FIG. 17A to those shown in FIG. 18A so that while the lower wall, 462(and 462A, 462B and 462C), of each of the runners as 451(and 452-4) continues to bear the longitudinal stress from bar 472, each increment of the sheet 455 is evenly bent along its length, as shown in FIG. 18, without developing any such protrusions of mass 597 as would otherwise develop from concentration of stresses during loading of the loaded pallet assembly 590 on a transport assembly 570. Protrusions of portions of the seed cotton mass 597 beyond the side surfaces of the mass weakens the tarpaulin attachment of assembly 590 and causes loss of cotton in transport and promotes irregular drying of the mass on top of the pallet.

In the operation of drawing the pallet into the transport, the uniformly transversely bent and grooved surface of sheet 455 and its mode of attachment to the runners 451-4 provide for smooth flexure of all of the corresponding increments of length of sheet 455 as the loaded pallet assembly 590 is moved from the ground 552 onto the sloped loading platform 574, as shown in FIGS. 3 and 18 and 19A-D, as well as similar flexure when the pallet is moved from the transport loader to the ground.

FIGS. 19A-19E diagrammatically illustrate stages in the operation provided by the pallet 450 in the system 421. As diagrammatically shown in FIGS. 19A-19E, the shape of the mass of seed cotton 597 on the pallet 450 changes while the loaded pallet assembly 590 is drawn up the ramp bed 571.

At the beginning of the loading operation, as shown in FIG. 1, the front portion of the mass of seed cotton 597 essentially has a vertical front surface 611, a vertical rear surface 614, a horizontal top front surface 612, a horizontal rear surface 613, a horizontal bottom rear surface 615 and a horizontal front bottom surface 616. On initial movement of the mass 597 up the ramp 574, as shown in FIG. 19A, toward position shown in FIG. 3, the portion 626 of the mass 597 bounded by the small upwardly tilted surface portions 612 and 616 immediately to the rear of front surface 611 forms a thin parallel epipedal mass 626 with the remainder 627 of the mass 597 defined by the surfaces 612, 613, 614 and 615 substantially in the same orientation as when assembly 590 was stationary and resting on the ground, generally as shown at the left side of FIG. 1.

As more of mass 597 is drawn up the ramp 571 by the cable 568, the parallelepiped mass 626 to the front of the junction of of the rear end 575 of trailerbed 570 and the ground 552 (i.e., at angle 547 or 551) increases in length. The mass 627 to the rear of apex of angle 551 does not have its shape changed during the initial movement of the mass 597 up the ramp 571 so long as the mass 627 to the rear of plane 618 is very large relative to, and much larger than the mass 626 (which mass 626 is located forward of apex of angle 551) because of the ready deformability of the mass 597 of seed cotton mass 626 is (as shown in FIGS. 19A and 19B) distorted to a parallelepiped shape; therefore, the front surface 611 remains parallel to the position of that surface (611) in its rest position (shown in FIG. 1) for that surface. However, by the time, in the process illustrated, a sufficient portion of the mass 597 has been moved up the ramp 574 so that the length of horizontal surface portion 613 and tilted surface portions 612 (along the top of the mass 597) are about equal, the front surface 611 of the mass 597 has an angular position -- shown in FIG. 19C -- relative to the upper surface of bed 571 of trailer 570 that is, generally, almost perpendicular thereto; such angular position of surface 611 is between

a. the angular relation of surface 611 to the ground 552 at the rest position of the mass 597, as shown in FIG. 1 (where it is, i.e. substantially perpendicular to the ground); and

b. the vertical position (shown in solid lines in FIGS. 19A and 19B and in FIG. 19C in dotted line 611A).

Initially, in the sequence of operations shown in FIGS. 19A to 19E, the rear surface 614 of the mass 597 of assembly 590 is in the same angular position relative to the ground surface 552 as it was in the rest position of FIG. 1, but, as the mass 590 moves from left to right, as shown in FIGS. 19A-19E (note that the position of apex 551A of angle 551 is stationary), the length and size and weight of mass 626 (to the front of apex of angle 551) exceeds the length and size and weight of mass 627 and surface 614 becomes more parallel to surface 611, as shown in FIG. 19D and in full lines in FIG. 19E (tilted counterclockwise).

FIG. 19E shows in full lines the assembly 590 fully supported on the tilted bed of the trailer 570 while the thus loaded trailer 570 is shown in dotted lines in position for being drawn by tractor 424 and being drawn thereby.

During this procedure of change in orientation of surfaces 611 and 614, there is a substantial period of time wherein a zone 619 composed of mass of seed cotton of shape of a trienated circular sector or wedge and bounded by surfaces 618 and 617 in FIG. 19C and 19D is formed above apex of angle 551.

Mass 619 is formed concurrently with the change in shape of mass 597 from a shape symmetrical about a central vertical plane 19F (shown in FIG. 19A) as in FIG. 1 (wherein the top [including portions 612 and 613] is straight as is the bottom surface) and the seed cotton therein is evenly compressed to an asymmetric shape as in FIG. 19C, which develops compression between adjacent zones of volumes 626 and 627 immediately below surface portions 612 and 613. The pallet 450 above the apex of angle 551 however, is sufficiently strong although flexible to support the portion of the mass 619 thereabove sufficiently firmly to urge the seed cotton mass above such curved pallet portion upwards so that projection of a first plane 617 perpendicular to the surface of the bed 571 whereat the bottom surfaces of the pallet runners 451-4 are spaced away from the surface of the bed 571 and the projection of a second plane 618 perpendicular to the surface of the ground 552 whereat the bottom edge of pallet runners 451-4 are spaced away from the surface of ground 552 meet at a line 624 which is located substantially above the intersection of top surface 612 and 613 of the mass 597 as shown in FIG. 19C and 19D, usually at least one-third of the height (surface 615 to 613) of mass 597 above the top of mass 597 measured at the line -- at apex 551A of angle 551 -- whereat the plane of the bed 571 meets the surface 552. Thereby the compression of the mass of seed cotton immediately below the top of surface 612 and 613 and above the line (551A) whereat the plane of the trailer bed 571 meets the surface of ground 552 is so reduced that no lateral or horizontal extrusion of that mass 597 occurs.

A part of this upwardly urging action by the curved portion of the pallet 450 is due to the engagement of the bottom of mass 597 and the corrugated surface of sheet 455; such engagement serves to fix the ends of any and each curved portion of runner as 451-4 as each such portion, as shown in FIG. 18, extends between ground 552 and surface of bed 574 while the loaded pallet assembly is drawn up the sloped bed past apex 551A of angle 551. This action of the runners and surface 455 to be bendable at bottom of zone 619 yet extremely strong to provide only a small angle between planes 617 and 618 as measured at their junction at line 625 is due to the limited but definite bowing of the side walls as 461 and 463 permitted by the lack of connection of the top edges of those side walls to each other except at spaced apart connections, as 560 and 561, to sheets 455; while such permitted bowing, as shown in FIG. 18A, results in bending of the runners between such points sufficient to form a small curve, as shown in FIG. 18, which is permitted by ready compression of plate 455 parallel to length of edges 501 and 502 of sheet 455 while each runner as 451 bows outwardly as shown in difference in shape of sections in FIGS. 17A and 18A. The bending of each runner as 451 beyond such predetermined initial amount is vigorously resisted by the resistance to any further lateral displacement (parallel to edge 503 of plate 455) of portions of flanges 464 and 465 attached to sheet 455. Such control of displacement provides the flexibility yet strength needed to provide the limitation to development of compression on upper portion of seed cotton mass 597 such limitation of compression in mass 597 preserves the stability of such loaded pallet assembly 590 that would otherwise be lost in loading it on transport 570 notwithstanding the care taken to develop such even compression and stability in assembly 421. As the mass of seed cotton 597 has substantially no tensile strength, once extruded, because of the development of such compressive stress, such seed cotton mass would, absent such action of the deformable pallet 450 as provided herewith for loading on a transport as 570 be left with irregularities at the sides of the mass and the loosening of the tarpaulin at its top.

While the above discussed compressive relations in mass 597 are shown as occurring in FIG. 19C at the middle of the mass 597 during the drawing of loaded pallet assembly 590 up the ramp 571, the procedure of relieving of stress at the top of the truncated wedge portion as 619 formed between relatively dimensionally stable masses of compressible material as shown in FIGS. 19C and 19D, occurs also in the mass 627 to the rear of the position of zone 619 in FIGS. 19C and 19D. The above discussion of relief of potential compressive stress at top of zone 619 in mass 597 by the above described action of the pallet 450 occurs at those portions of mass 597 to the rear (toward surface 414 as well as at portions of mass 597 to the front (towards surface 611 of portion of pallet assembly 590 relative to apex 551A shown in FIG. 19C, as the flexibility and limited distortion of the pallet 450 provides for relief of stress in the upper portions of the cotton module mass as would otherwise cause irregularities in its outer surface resulting from high degrees of compression. Such relief is effected by the pallet 450 for the mass 597 in the zone extending from one-fourth of distance from the rear surface 614 to the front surface 611 of the mass 597 to three-fourths of that distance and transport of the loaded pallet 590 on the trailer 570 as shown in FIG. 19E, occurs without loss of cotton by being carried away by the wind during transport due to irregular side surfaces.

The top surface 574 of the bed 571 supports the loaded pallet assembly 590 after such assembly is drawn on the trailer bed. During transport on trailer 570 the bars 472 and 474 of pallet 450 provided attachment to ropes or chains to firmly attach the loaded pallet assembly 590 to the tie downs as 579 on 579' for the trailer bed hooks.

Unloading of the loaded pallet 490 is accomplished from trailer 570 without undue compression and sideways seed cotton extrusion development in the same manner as loading onto trailer 170 is accomplished without such undue compression as produces seed cotton extrusion during loading as above described for the loading of the pallet assembly 590. Accordingly, storage of the loaded pallet 590 at the gin yard after discharge of the loaded pallet assembly from the trailer 570 is accomplished without development of any irregularities in the surface as would (otherwise) provide for undesirable and excessive drying in selective points of the mass 597.

After transport thereon to the gin yard, assembly 590 has sufficient dimensional stability to be discharged from trailer to ground to await later transport to the gin while maintaining a high and substantially uniform bulk density for later transport to and rapid handling at the gin.

After removal of the mass 597 and tarpaulin 592 at the gin, the pallets are very readily handled and nested for return to field for later use, as above described. The pallets 450 are each sufficiently light for ready manual handling (of one at a time) by only two operators holding bars 472 and 474 whereby the bottom of one pallet is readily placed adjacent the top surface of another to form a readily transported nest of such pallets, as pallet 450 herein described weighs 400 pounds.

The location of center of bar 472 is, as shown in FIG. 16 -- which Figure is drawn to scale -- in line with top of plate 455 so that drawing of the pallet 450 along the bed surface 574 by cable 568 does not cause bending of the mass 597 as would increase compressive stress in the upper portions of the mass 597 after the bottom walls as 462-462C of each runner as 451-454 is located on the surface 574 of bed 571.

The cables 591 on the loaded pallet assembly 590, in the position shown in FIG. 1, which position is a position of such assembly while in the field on the ground surface 552 on which such loaded pallet assembly 590 is formed in the mobile press assembly 421, as above described, permits that the cables attached to the grommets and the tarpaulin above the mass 497 may move within the eyes as 644 of the hooks as 595 (and 481-4) of the loaded pallet assembly 590 while held in tension by the weights 598 and 599. The hooks 595, with the eye 644 thereof, also permits that the cables will permit movement of the tarpaulin 592 on top of the mass 597 when the mass 597 changes its shape as hereinabove described and shown in FIGS. 19A-19E during the process of movement of that mass 597 from its position on the ground surface 552 onto the inclined bed 574 of the trailer 570 when such longitudinally continuous mass of seed cotton 597 is moved from its position as shown in FIG. 1 through the stages shown in FIGS. 19A-19E. During such movement as shown in FIGS. 19A-19E, the top surface of the longitudinally continuous mass of seed cotton 597 provides an upwardly concave surface at the juncture of surfaces 612 and 613 of the mass 597 as well as a downwardly convex surface above apex 515A of angle 551 where the lower portion of the wedge-shaped or truncated sector-shaped portion 619 contacts the top of the curved portion of the pallet 450 which curved portion is shown particularly in FIG. 18. Accordingly, the cables as 591 permit the distance from tarpaulin grommet to pallet hook eye as 644 to increase against the resiliently yieldable tension of cables 591 and 591' and movable weights 598 and 599 because those cables move freely through the hook eyes as 644 and thereby provide that the tarpaulin 592 be held to the support or pallet 450 by such cables 591 peripherally of the mass 597 in a resilient manner. The structure also permits that as the stress on one front set of cables adjacent the front surface 611 is increased consecutive increments of the longitudinally continuous mass 597 and the tarpaulin 592 thereover will cause the temporary elongation of some of the cables between the grommets of the tarpaulin and the eyes of the hooks connected to the L-shaped edge pieces 448 and 449 on the pallet 450. The ready removability of the hooks permits that operators may locate those hooks as needed and that during the stacking operations of such pallets for return of those pallets to the field at which their use is intended such stacking does not suffer interference because of interference by the hooks or loss and/or bending of such hooks. This structure also permits that the tarpaulin may be prepared (for later use by unrolling over the mass 597 as shown in FIG. 2) with the cables as 591 attached to the hooks as 595 by such cable passing through the eyes as 644 of each of such hooks and the hooks subsequently drawn down over the sides of mass 597 with the hooks attached thereto and said hooks then attached by arm end 241 hooking into an ell as 448 and 449 for the proper positioning of those cables and hooks onto the pallets 450. After the positioning of such hooks and cables, the weights 598 and 599 are applied to the cables as shown in FIGS. 1, 3 and 19E with the hooks then properly attached to the pallet 450, as shown in FIG. 14. The cables then firmly yet releasably draw the water-impermeable tarpaulin cover to the top of the mass 597. Such attachment also permits that the mass 597 can expand due to change in moisture content of the seed cotton and to relief of the pressure in said seed cotton mass; such expansion of the distance between the grommets of the tarpaulin and the fixed position of the hooks as 585 to the L-shaped side members as 448 and 449 of the pallet 450 is accommodated by that the eyes as 644 of each of the hooks as 595 permit the cable 591 to slide therethrough while bend 643 holds to the edge members as 448 and 449 of the pallet 450. The ability of these cables and hooks to accommodate changes in the distance of the grommets as 593 to the ells on the pallet 450 also provides that, during change of dimension of the portions of the tarpaulin on top of the longitudinally continuous mass 597 during the movement of that mass 597 from its position in the field 552 up the surface 574 of the inclined bed 571 of the trailer 570 that the resulting tension developed on the grommets of the tarpaulin will not rise to such value as will cause a compression of the cotton immediately under the tarpaulin or rupture the tarpaulin or produce extrusion of the seed cotton mass from the sides of the mass 597 nevertheless, the cables, grommets and weight provide a firm attachment of the tarpaulin to the mass 597 by virtue of the tension along all of the cables as 591 through the eyes as 644 of the separate hooks as 481, 483, 484 and 595 on each side of the mass 597 due to the effect of the weights 598 and 599 at the end of each such cables. Cable 591 extends along the right side of the mass 597 cable 591' extends on the left side of mass 597 from weight (tire) 598 to 599.

The pallet of said system comprises an imperforate water-impermeable transversely grooved thin corrugated sheet and a plurality of parallel longitudinally extending like runners, each runner composed of a two like vertically extending outwardly sloped side walls and a bottom flat smooth horizontal sheet, the side walls firmly yet resiliently joined at corners along the total length of their bottom edges to the total length of the left edge and right edges, respectively, of the bottom sheet and extending upwardly therefrom, and said sheet is firmly connected to the top of said side walls at regularly longitudinally spaced apart points. The tilt bed trailer of the system comprises a winch and a bed, said winch attached to said bed, said trailer bed having a length at least the length of said pallet.

The minimum radius of curvature on the bottom of said mass of cotton on said pallet moved onto the said bed is at least as great as the height of said mass of compressed seed cotton on said bed measured transversely to the horizontal surface covered by the edges of said bed. The pallet sheet is an imperforate sheet with a plurality of like, parallel transversely extending upwardly convex grooves and downwardly convex portions thereon and the bottoms of said upwardly convex portions contact said runners and the top of each of the runners is firmly joined to the bottom of said sheet at portions of such sheet that are spaced apart from each other by greater distances than the points of contact of said sheet and said runners and wherein the height of said sheet varies in periodic and uniform continuous manner from lowest points to highest points, and intermediate portions of the sheet extend vertically therebetween and are continuous therewith and provide support for said horizontally extending portions and said points of firm connection of the side walls on each runner to the bottom surface of said sheet are abreast of each other and points of attachment of all the runners to the bottom surface of sheet are also abreast of each other. The pallet length is less than the length of the feeder assembly chamber 39.

In operation, a tractor as 424 drawing a trailer as 570 carries a loaded module of cotton 590 on top of a pallet as 450 and passes to one side of the chamber 39 with the pivotal door assembly 434 then in the raised position, as shown in part C of FIG. 25. The operator of the tractor 424 stops when the rear end of the trailer 570 is adjacent but only slightly removed from the forward end of the door assembly 434 in its lowered position. The door assembly 434 is then lowered to its lowered position, as shown in FIGS. 21 and 22.

The positioning cylinders 278 and 279 provide for moving the loading frame 240 laterally and centrally to locate such frame in line with a tractor as 424 and trailer as 570. This ability of the loading assembly 240 to move relative to the frame 150 permits a rapid and convenient loading of the module 597 and pallet 450, carried on the trailer 570 to be conveniently and readily aligned so as to be rapidly and, without skewing, carried on the movable load frame 240 for subsequent movement into the feeder assembly chamber 39.

The movable door frame assembly 240 may be moved outwards of the longitudinal lefthand side member 153 of the feeder assembly frame 150 by extension of the cylinders 278 and 279 that serve to move the movable frame assembly 240 laterally. This movement provides for alignment of the central slot 249 of the frame assembly 240 with a bracket 630 attached to the pallet 450 and also provides for locations of the runners of the pallets as 450 in line with the rows of rollers 280, 281, 282 and 283 of the assembly 240.

A chain drive 292 actuated by a winch 293 on the frame 240 draws the module 590 of cotton into position from the trailer 570 as shown in FIG. 21, to a position abreast of the chamber 39, as shown in FIG. 22.

In a particular examples of this operation, the loaded module 597, which has an overall size of 71/2 feet wide, by 71/2 feet high, by 24 feet long and has an overall density of 12 to 14 pounds per cubic foot and weighs about 15,000 pounds, is thereby loaded on the frame 240. On contraction of pistons 209 and 210, the loaded pallet is held on frame 240 by the clamp bar 190, and is moved inwards on contraction of the auxiliary pistons 278 and 279. The apron 250 is then located below the top of frame 240 (supporting the pallet 450 and the mass of cotton 597 thereon). The frame 240 is then moved centrally toward the chamber 39 to a position as shown in part A of FIG. 25 so that its central longitudinal edge member 246 is substantially adjacent to as well as parallel to the feeder assembly frame member 158. The next step in the operation is that the pivotal frame assembly pistons 101, 102, 103 expand and pivot the pivotal frame members 233, 235, 237 and the remainder of assembly 34 carried thereon to a vertical position, (25C as shown in FIG. 25). Prior to reaching such vertical position, while the module of cotton is at a oblique angle relative to the horizontal, the module breaks and falls into the chamber 39. The further movement of the module from position 25B to 25C results in a more complete breaking up of the theretofore dense and formed module. Accordingly, the operation of the pivotal door 34 provides that the module 590 carried by the frame 240 is pivoted and tipped about its right lower corner (right side as shown in FIG. 25) and also collapsed (as shown in FIG. 25C) or broken while being transferred into the chamber 39. The apron 250 is then retained in position by a separate locking mechanism therefor, the hydraulic piston 127 as shown in FIG. 25.

Once the mass of cotton bolls and trash theretofore in the cotton module has been located on top of the conveyor belt 147 as a cotton mass 139, the top of the conveyor belt is driven by its motor and moves that mass toward the disrupter assembly 41.

The belt 147 has, for cotton bolls, a very low coefficient of friction or, for practical purposes, an extremely smooth surface as measured along its length, as shown by the very light force developed by such a belt against movement of a mass of cotton in the mass 139 along the length of such belt. The belt 147 is made by Cambridge Wire Cloth Company of Cambridge, Md. 21613, and described in their Brochure No. 148 of 1973 as a Gratex balanced belting. It is formed of flattened helically arrayed round steel wire 1/8 inch in diameter arrayed in spiral loops 284-7 with a 1 inch interior major diameter and a 1/4 inch minor diameter. The spiral wire is wound around transverse straight wires 294-298, each 5/8 inch center to center, and arrayed transverse to the length of the belt. Measured along the length of such transverse wire, there are 16 loops per 51/2 linear inches. The spacing or pitch between wires in such spiral array is 1/4 inch between adjacent wire edges and adjacent helixes are wound around the same transverse wire in opposite directions.

The chain conveyor belt 147 is supported on flat nylon sheets 141-2 which maintain the bottom of the chain 147 in a flat surface and avoid any dipping as might cause compression of the cotton mass supported thereon.

The moving belt 147 creates definite but relatively feeble force on the rear end of the bottom of the mass of cotton which force is developed and exerted by the adhesion of the chain belt against the mass of cotton thereabove.

The mass of cotton initially deposited by door 34 on conveyor belt 147 is a loose mass and a one inch diameter broom handle may be pushed by hand one foot into the rear portion of such mass 139 on its initial deposition on the belt 147. The belt 147, driven by its motor under the control of an operator of the machine 30, moves the mass 139 towards the operating assembly 60 whereat a substantial rearward force is developed against forward motion of the cotton mass 139 and the bulk density of the mass 139 is increased. With increased proximity to the disrupter assembly 41, the cotton mass 139 becomes increasingly compressed to a greater bulk density (as 15 pounds per cubic foot).

Because of the low frictional force between the belt and the cotton mass, the length of the zone extending backward from the reel unit 60 to the wall 33 through which mass such increased density occurs -- such increased density is 14 to 15 pounds per cubic foot -- increases as the rate of feed to the reel assembly 60 increases from 0 to 4 feet per minute along the belt 147. The area of contact of the compressed mass of increased bulk density with the surface of the belt increases correspondingly to the speed of the belt. The compressed and elastic mass thereby developed provides a relatively even amount of pressure applied against the mass of cotton in the zone 129 immediately adjacent the zone occupied by the teeth of the disrupter reels of assembly 60 whereby a substantially even feed is provided into the disrupter dispersing assembly. As there is a relatively even beating action by the disrupter assembly on the mass of cotton fed to the reels 61-66, the product from the disrupter assembly has an extremely uniform and self-regulating bulk density.

The apparatus and process of apparatus 30 thus provides for maintaning pressure in the mass 139 by the drive belt as an elongated elastic mass whereby the disrupter mechanism operates at a stable pressure of feed and effects a uniform separation of bolls and various trash. Notwithstanding the apparent delicacy and softness of cotton fiber, the high tensile strength thereof (60 to 120,000 pound to the square inch compared with 50 to 80,000 pounds to the square inch for steel wire) permits that the high intensity of beating action applied thereto according to this process and apparatus is particularly effective in separating the only lightly adherent trash, twigs and leaves from the cotton as well as disrupting the shell of the cotton bolls and making ginning of the cotton subsequently more efficient.

All of the reels 61-66 of the reel unit 60 are rotated counterclockwise, as seen from the left side (side 163 shown in FIG. 22) by operative connection to the motor 40 under control of the operation at control station 110 of the apparatus 30. The axes of all of the parallel shafts 61.5, 62.5, 63.5, 64.5, 65.5, and 66.5 of the units 61-66 lie in a flat plane tilted toward the rear wall and at 75.degree. to the horizontal -- while the top surface of belt 147 is horizontal.

To provide adequate orifice space for passage of the thus threshed cotton, the open space between vertically adjacent reel units of the entire assembly 60 is approximately one-third of the total cross-section area measured in a vertical plane parallel to shafts as 62.5 of that assembly. In the particular example given, the teeth as 175.5 are each made of round steel rod, 1/4 inch in diameter, and the terminal portion thereof extends 3 inches peripheral to the top edge of the rod as 201 on which each such tooth is supported. For each unit as 62.2, the bottom edge of plates 46 and 47--12 inches in diameter--of unit 62.2 are at the same vertical height as the top of the upwardly directed teeth of the unit 61.2 therebelow as shown in FIGS. 30 and 31 and the top edge of plates 46 and 47 of unit 62.2 are at the same vertical level as the bottom edge of the teeth in the unit 62.3 thereabove, generally as shown in FIGS. 26 and 30. FIG. 24 is pictorial, hence does not illustrate such relationship although FIGS. 30 and 31 illustrate to scale some three dimensional aspects of the assembly 60.

In operation, the reel teeth of the disrupter assembly are moved by the motor 40 at a sufficiently rapid rate of speed, about 600 to 700 r.p.m., to provide at the end of each of the teeth a peripheral speed of 3,000 feet per minute or 50 to 60 feet per second. Such speed is sufficiently rapid to beat and tear rather than only pull the material contacted by such teeth. The beating and tearing loosens the cotton in the bolls from the adjacent stalks, leaves and entrapped trash in the mass 597 and 139. This disrupted material 140 thus drawn from the mass 139 is thrown to the front of the line of disrupter reels 61-66 into the space 50 (see FIGS. 20 and 23) above the conveyor belt 52 of the separator assembly 51.

The condition of the material 140 discharged by reel assembly 60 as well as the operation of portions of the assembly 60 may be observed through the windows 166-170 in walls 163 and 164 and the operation of fans 53 and 83 observed through window 171. A conveyor belt 52 supported on frame 152 for movement transverse to the belt 147 is driven by a belt motor 49 supported on frame 152 therefor and operatively connected to the belt 52 for driving thereof under control at control station 110 dependent upon the observation of operation of the product in trash assembly 59 and product observed in window 171. Assembly 110 is connected to a source of power to operate all motors and cylinders of apparatus 30. A fan 53 on hood 160 is connected to upper end of duct 54 and powered by a motor 48 therefor operatively connected to a source of power through control assembly 110. The size of orifice 55 over belt 52 is adjustable by the vertical movement of throat plate 45.

At the discharge of the belt 52 (shown in FIG. 34) a separating chamber is formed whereat the fan 53 creates a draft of air through a duct inlet 55 and drives that air and the cotton carried therewith through duct 57 to the outlet 56 thereof into a collector 80 for the cotton while the trash, i.e. the twigs and shells of the cotton bolls are collected in the trash collector assembly 59.

Trash collector assembly 59 comprises a trash collector chute 257 a trash conveyor 258 and a trash collection chamber 259 in operative connection, as shown in FIG. 21.

Because the disrupter reel units as 61-66 separate the seed cotton bolls from the trash in such a manner as to fluff up the cotton bolls during such process of treatment (by assembly 60), the air stream provided at the duct inlet 55 lifts up the seed cotton bolls from the belt 52 and leaves the heavier materials theretofore intermixed therewith in mass 597 (sticks, rocks and heavier bolls) to be conveyed to and discharged from the end of the belt 52 to the collector assembly 59. Accordingly, apparatus 30 provides a separation of the trash and boll components from the mass 597 prior to the disrupted or dissociated mass 140 entering a gin. This preparation and separation saves ginning time, saves wear or machinery and pollution by avoiding polluting air with the separated trash and as well as reducing the density of the mass of seed cotton economically transported on pallet 450 (and thereby avoid clogging or interfering with best performance of a gin).

While the discharge of duct 57 is shown in FIG. 21 as passing to a collector chamber 80, such collector chamber may be part of a gin building 85 and one stage in a conventional gin treatment by a train of apparatus comprising a boll trap 81, an unloading separator 82, a fan 83, and a cyclone 84; also, the discharge of duct 57 may pass directly to such train of apparatus as to member 81 thereof in the gin building 85 rather than through the intermediate storage 80.

A fan transition piece 54.7 is used as the inlet from the upper end 54.6 of the duct 54 to the inlet of fan 53 when the duct 54 feeds to fan 53 on apparatus 30. However, other transition pieces, as double fan transition pieces 87 and 88 are connected to top of duct 54 and used when the upper end 54.6 of the duct 54 feeds directly to a plurality of ducts as 88 and 89 (as shown in FIGS. 34 and 35) as are conventional in feeding to a pneumatic system in a gin (as in building 85) powered by its own fan as 83. The separation of field trash from seed cotton bolls at the end of belt 52 of apparatus 30 is still effected as above described (for operation when fan 53 is connected to duct 54) when the separating duct 54 is connected to the gin fan, as 83 as shown in FIG. 35, although the source of pneumatic power is then the fan 83 in the gin building 85. An operator 100 is illustrated in FIG. 32 to show the approximate size of the equipment discussed.

By this process and apparatus, the irregularities in composition and density resulting from the gathering of natural product from different areas of ground from which usual cotton crop is harvested, provides that the bottom zones of a mass as 597 which would be the material first formed into the mass 597 and generally the materials first gathered at a particular harvesting operation) would be somewhat different in composition from the upper zones thereof which are later harvested or picked. By the process of this operation, the turning of the module mass provided by the motion of the door 34 shown in FIG. 25 provides that the material initially on the module bottom is then located near the apron wall adjacent the door 34 and the material initially at the module top is located adjacent the side wall 32, as shown in FIG. 25 (part C) when located in chamber 39. This turning operation thus provides a relative uniformity from what had been a dissimilar feed and a more uniform operation and better grade results in the gin to which the collected material from apparatus 30 is fed.

The length relationship above described in reference to teeth of embodiments of FIGS. 30 and 31 is an alternative to the relationship of Table I and FIG. 24. In the embodiment of Table I, the upper ends of teeth as 175.5A of a lower unit as 61.2 extend to a vertical height that is 7/8 inch short of the vertical level of bottom edge of reel plates 46 and 47 of unit 62.2 thereabove, although, as in embodiment of FIG. 30, the upper end of each of the teeth, as 175.5A, of the lower unit (62.1) always extend to a greater height than the lower end of each of the teeth as 175.5 of the unit (as 62.2) thereabove. The overlap of the vertical extensions of the teeth of the upper and lower units of Table I is 11/8 inch total rather than the 27/8 inch for such overlap in the embodiment of FIGS. 30 and 31. The speed of the belt 147 may be controlled by an operator at control station 110 dependent upon his observation of the condition of the mass of cotton in window 170 or the sounds of the reel unit 60 against the mass 139 indicating the teeth thereof contact each increment of such mass with adequate impact.
