Snowplow Assembly Quick Block and Pin Disconnect for a Payloader

1. Field of the Invention

The instant invention relates generally to snowplows and more specifically it relates to a snowplow asseably for a payloader or the like.

2. Description of the Prior Art

Numerous snowplows have been provided in prior art that are adapted to be attached to various motor vehicles such as sanitation vehicles, tow trucks, etc. to remove snow from roads and railroad tracks. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.

A priary object of the present invention is to provide a snowplow assembly for a payloader or the like that will overcome the shortcomings of the prior art devices.

Another object is to provide a snowplow assebly for a payloader or the like that can be quickly attached to and reoved from the bucket of the payloader

An additional object is to provide a snowplow assembly for a payloader or the like, that is approxately five ties as large as the bucket of the payloader so as to increase the surface of the blade for faster removal of snow from roads.

A further object is to provide a snowplow assembly for a payloader or the like that is simple and easy to use.

A still further object is to provide a snowplow assembly for a payloader or the like that is economical in cost to manufacture.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

FIG. 2 is a side view thereof with the payloader broken away.

FIG. 3 is a partial exploded perspective view of the quick connect block unit.

FIG. 4 is a partial exploded perspective view of the quick connect pin unit.

FIG. 5 is a partial perspective view of the quick connect block unit and modified quick connect pin unit on a machine push arm of a rubber tire dozer or the like.

FIG. 7 is a cross sectional view taken along line 7--7 in FIG. 6.

FIG. 8 is a diagramatic side view of the blade without the replaceable wearing trailing edge member engaging and being stopped by an obstruction on the ground.

FIG. 8A is a diagramatic side view of the blade with the replaceable wearing trailing edge meber engaging the obstruction.

FIG. 8B is a diagrammatic side view silar to FIG. 8A with the replaceable wearing trailing edge member riding up and over the obstruction.

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 and 2 illustrate a snowplow assembly 10 for a payloader 20 that has a bucket 18. The snowplow assebly 10 consists of a pair of quick connect pin units 16, a pair of quick connect block units 21, a pair of push arm frame units 14 and an elongated snowplow blade 12.

Each of the pin units 16 is secured to one rearward end of the bucket 18 of the payloader 20, each of the block units 21 is reovably claped onto one of the quick connect pin units 16 and each of the frae units 14 is secured to one of the block units 21. The elongated snowplow blade 12 is affixed to both of the push arm frame units 14 so that the snowplow blade 12 can extend in front of surface "B" of the bucket 18 of the payloader 20 with an increased surface "A" for fast reoval of snow from ground 62.

As best seen in FIG. 4, each of the quick connect pin units 16 includes a pair of inner plates 36, an outer plate 34, a socket 38, a push pin 40 and three spaced apart stop rings 42. Each inner plate 36 has an aperture 37 therethrough and is perpendicularly affixed spaced apart to the rearward end of the bucket 18 of the payloader 20. The outer plate 34 has an aperture 35 therethrough and a portion of the outer plate 34 is affixed to side of the bucket 18 of the payloader 20 so that the aperture 35 of the outer plate 34 and the apertures 37 of the inner plates 36 are in alignment with each other. The socket 38 extends through the apertures 37 in the inner plates and the outer plate 34 and affixed thereto while the push pin 40 slideably fits within the socket 38. The three spaced apart stop rings 42 are affixed to the push pin 40 near one end and accurately spaced to provide a quick hook-up block member 22 and push pin 40 thereof so that the inner most of stop rings 42 can bear against the outer plate 34.

A device 43 is provided for holding the push pin 40 stationary within the socket 38 and includes a rod 44 that extends transversely through the socket 38 and the push pin 40. A chain 46 has one end affixed to the rod 44 and other end affixed to the rearward end of the bucket 18 of the payloader to prevent loss of the rod 44.

As best seen in FIG. 3, each of the quick connect block units 21 includes a stationary block meber 22 and a reovable block member 26. The stationary block member 22 is generally U-shaped and has half of an aperture 23a therethrough while the reovable block member 26 has other half of the aperture 23b therethrough. The removable block member 26 fits into the stationary block member 22 thus completing the aperture 23 therethrough so that the push pin 40 can fit at a right angle therein with other two stop rings 42 therebetween.

A device 29 is provided for holding the removable block member 26 stationary within the stationary blcck meber 22 and includes a rod 30 that extends transversely through the stationary block meber 22 and the removable block member 26. A first chain 32a has one end affixed to the rod 30 and other end affixed to the stationary block member 22 to prevent loss of the rod 30. A second chain 32b has one end affixed to the stationary block member 22 and other end affixed to the the removable block member 26 to prevent loss of the removable block member 26.

FIGS. 6 and 7 further show an elongated bent adapter edge member 54 mounted by fasteners 56 along lower edge of the snowplow blade 12. An elongated replaceable wearing trailing edge member 58 is mounted by fasteners 60 along lower edge of the elongated bent adapter edge member 54 so that when the snowplow blade 12 encounters an obstruction 64 in the ground 62 the replaceable wearing trailing edge member 58 can ride up and over the obstruction (see FIGS. 8, 8A and 8B).

FIG. 5 shows a snowplow assembly 10a for a rubber tire dozer 43 having a pair of machine push arms 47 (only one shown in drawing). The snowplow assembly is similar to assebly 10 except for the quick connect pin units 16a, which are secured to one side of the push arms 47 of the dozer 43. The snowplow blade 12 (not shown in FIG. 5) can extend in front of the rubber tire dozer 43 with an increased surface for fast removal of snow from the ground 62.

Each of the quick connect pin units 16a includes a pair of arm plates 45, a mounting plate 48, a pin 50 and two spaced apart stop rings 52, one of the arm plates 45 is mounted along bottom edge by welding to top edge of the machine push arm 47 while other of the arm plates 45 is mounted along top edge to bottom edge of the machine push arm 47. The mounting plate 48 is secured to the arm plates 45 by fasteners 49. The pin 50 is affixed to center of the mounting plate 48 and extends outwardly therefrom while the two spaced apart stop rings 52 are affixed to the pin 50. In all other respects the assebly 10a is like assembly 10.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of methods differing from the type described above.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the at without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
