Description
Field of the Invention
The invention relates to rug hooking devices and relates particularly to such devices in which the base material upon which the hooking operation is being performed may be positively held but incrementally fed as desired by the operator and further in which there is provided hold-down means for positive holding against fixed means a portion of said base adjacent that upon which the hooking operation is being performed.
Background of the Invention
The so-called "hooking" of rugs is an old art and many devices have been proposed over the years for facilitating same. In a more recent development of this art, there has appeared a procedure wherein a sheet of flexible base material is provided with suitable openings therethrough, as by being woven with a large mesh, wherein the base material is fed to the operator under a controllable restraint and wherein the hooking operation is performed by introduction of the desired rug materials into and through such openings in said base. This development of the art has also given rise to a large number of devices by which the base material may be held and fed to the operator as desired with the finished portion of the rug then moving to some portion which is clear of the working zone. These devices in greater or less complexity have in the past provided means for holding the base material and incrementally feeding it into a working zone as required by the operator and they have done so with greater or less degrees of convenience to the operator. However, in the operation of rug hooking, it is further desirable to provide means for holding said base substantially immovably in a zone close to the working zone and none of the prior devices of which I am aware provide this function. The need for same has been recognized in the past inasmuch as certain instructions for rug hooking have suggested placing weights, as books, on top of the base adjacent the working zone but none insofar as I am aware have provided means for such holding within the structure of the rack itself.
Accordingly, the objects and purposes of the invention include:
1. To provide a rug hooking rack for supporting and incrementally feeding a base material to a working zone which rack will be simple to make, effective in use and easily converted from a collapsed to operating condition and vice versa.
2. To provide a rug hooking rack, as aforesaid, which includes also clamp structure by which the operator may if and when he so desires hold such base material firmly against fixed means at a point adjacent the working zone whereby to improve the firmness with which a hooking operation may be performed with respect to a particular segment of such base material.
3. To provide a rug hooking device, as aforesaid, which may be expressed in either a relatively simple and portable table model and/or in a somewhat more permanent free-standing model.
4. To provide rug hooking devices, as aforesaid, which will be extremely simple in manufacturing but will be durable and capable of long and satisfactory use.
5. To provide rug hooking devices, as aforesaid, which will hold such base material firmly when the operator so desires but which may by a simple manipulation be enabled to advance such base material incrementally as desired by the operator.
6. To provide rug hooking devices, as aforesaid, which will operate easily and freely when so desired by the operator but which when in clamped condition will hold a base material firmly against any strains normally placed thereon by the rug hooking operation.
Other objects and purposes of the invention will be apparent to persons acquainted with apparatus of this general type upon reading the following specification and inspection of the accompanying drawings.

Detailed Description
Referring first to FIGS. 1, 2 and 3, there is provided frame structure comprising legs 1 and 2 connected together at their respective upper ends by any convenient longitudinal element, here a shelf and light shade S, and strengthened by a brace 3. Similar structure is provided at the other end of the machine and comprises legs 6 and 7 and a brace 8. A further longitudinal element 11 connects the two brace members.
Table structure is provided comprising a brace member 13 removably fixed as by bolts to the leg members 1 and 2. A similar brace member 14 is similarly fixed to the leg members 6 and 7. A table 16 connects the table support members 13 and 14. A roll 17 is pivotally mounted on the table support members 13 and 14 and is fixed for incremental advancement by any convenient means, such as an opening 18 in the support member 13 registerable with a selected one of a series of selectable openings 20 in the end of the roll 17 into which a pin 19 can be inserted.
The base material for the rug hooking operation is wrapped around the roll 17, extended across the top of the table 16 and back out of the operator's way, preferably by being led above the longitudinal member 11.
A light 21 and shade S may be provided if and as desired. The light shade S may also include shelf structure 22 which will further function as a connecting member between the end structures.
Forward clamp structure 23 is in this embodiment provided by a clamp member 24 pivoted at its one end at 26 to the leg 2 and its other end 27 to the leg 6. The spacing of said pivot point 26 (and its counterpart at the other end of clamp member 24) from the surface of the table 16 is such that the clamp will interfere with and bear against said table when same is rotated in a counterclockwise direction as viewed in FIG. 1 but same can be released from such contact with said table upon rotation in a clockwise direction as viewed in FIG. 1. A resilient device, such as the spring 28, is fixed between the clamp 24 and a suitable anchor point, such as the anchor point 29 on leg 1, and continuously urges said clamp for rotation in a counterclockwise direction. A handle 31 may be provided if desired to facilitate manual pivoting of said clamp in a clockwise direction.
With the base material above mentioned extending from the roll 17 under the clamp 23 and across the table 16 as above described, the hooking operation is carried out adjacent the end of said table, normally in the zone Z. In such case, the pin 19 will be inserted into the opening 18 and a selected opening 20 in registry therewith on said roll to prevent rotation of the roll 17 and the clamp 23, being urged by the resilient means 28 against said base, will hold said base material down firmly against the table as desired to facilitate the hooking operation. When it is desired to advance such base material, the pin 19 is merely withdrawn sufficiently to free the roll 17 and the base material is pulled toward the operator the desired distance. When the base material is so pulled toward the operator, the clamp provides no interference and no manipulation thereof is desired. However, if for reasons of inspection or otherwise it is desired to release the clamp entirely, it is a simple matter to grasp the knob 31 to pivot the clamp as far as desired and when the reason therefor has been satisfied, the clamp may be released and it will resume its normal function as above described.
It will be apparent that by appropriate proportioning of the apparatus the clamp 23 may be placed adjacent the rearward edge of the table 16 as shown or it may be placed as far toward the forward edge of said table as desired. It is further possible by providing a further member 32 (FIG. 4) extending between legs 1 and 2, and similar construction at the other end of the frame unit, to mount the clamp adjustably as desired by the operator for any given hooking device. This provides a wide range of flexibility in the use of said clamp according to the desires of the operator.
Modification of Figs. 5 to 9
In this form of the apparatus, there is provided a base frame 41 comprising side members 42 and 43 and fixed end members 44 and 46. End member 44 is preferably fixed to extend downwardly from said side members in order to hook against the edge of a table as shown while end member 46 is provided across the top of said side members, and fixed thereto such as by screws 45, to provide a table functionally similar to the table 16 of FIGS. 1-3 adjacent the working zone Z. Said side members are provided with rows 47 and 48 of spaced openings for purposes appearing hereinafter. Openings 76 and 77 (FIGS. 7 and 9) are provided in end member 46 and are respectively in registry with a pair of the openings 78 and 79 in the side members 42 and 43. In this embodiment the rows of holes 78 and 79 are respectively offset from the rows of holes 47 and 48 (see FIG. 9).
An incremental clamp 49, corresponding functionally to the roll 17 in FIGS. 1-3 here comprises a pair of clamp members 50 and 51 which are held clampingly together in any desired manner, such as by bolts 52 and 53 and wing nuts 54 and 56. Pins 57 and 58 (FIG. 8) project from the lower clamp member 51 and are respectively receivable within the openings of the rows 47 and 48. Thus, a sheet of base material may be placed between said members 50 and 51, the wing nuts screwed down to fix same firmly therebetween and the pins 57 and 58 placed in the pair of openings furthest from the end of table member 46. As work progresses, the clamp member 49 is advanced one pair of openings at a time, or more if the operator so desires, along the rows 47 and 48 until the clamp 49 reaches a position close to the table member 46 at which said clamp may be relocated and the process repeated.
There is also provided a further clamp 63, corresponding functionally to the hold-down clamp 23 of FIGS. 1-3. This comprises a pair of members 64 and 66 which may be gripped together by any convenient manually operable means such as the bolt and wing nut assemblies 67 and 68 (FIGS. 6 and 9). In addition, further bolts 69 and 71 (FIG. 9) extend from the lower clamp member 66 through selected ones of the openings 76 and 77, together with the ones immediately therebelow of openings 78 and 79, and are fixed in place by wing nuts of which one appears at 74. Preferably, the bolts 69 and 71 of said clamp 63 will pass through the ones of the openings 76 and 77 (and 78 and 79) as to enable the clamp 63 to be as close as possible to the work zone Z. Thus, as the work is advanced by moving the clamp 49 forward as above described, it will be released and relocated in the hold-down clamp 63 by releasing the wing nuts associated with bolts 67 and 68, moving the work forward the distance desired and then retightening said wing nuts.
It will be seen that this form of the invention is very simple to make, can be rendered operational merely by placing same on a table as shown and may be lifted off from such table at any time desired when the work is interrupted and stored without the necessity of releasing the work from either of the clamps there provided. It is thus very simple and hence inexpensive to make but is extremely versatile and fully effective in use.
It will be apparent that functionally the lower clamp member 66 is in part a working surface spaced from the table member 46. Thus, if desired, and as illustrated in FIGS. 10 and 11, said lower clamp member may be eliminated and the upper clamp member 64 may operate directly on and with respect to the working surface of said table member 46. In such case, the table 46 is extended endwise to provide extensions 46A and 46B (FIGS. 10 and 11) and the bolts 67 and 68 extend into selected ones of a series of holes 86 and 87 therein.
A further possibility recognizes that one of the clamp members 64 and 66 may be a continuation of the working surface of the table 46, especially if said clamp member is placed in the position indicated by broken lines 63A in FIG. 7. Thus, one may provide clamp member 64 with the pins 81 and 82 which are sized and spaced to fit into a pair of the openings 47 and 48. With this, if desired, the clamp 63 may be inverted as shown at 63A and the pins 81 and 82 inserted into a pair of openings 47 and 48 whereby the lower member becomes flush with the table 46.
Although a particular preferred embodiment of the invention has been disclosed in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
