Description

Sept 28, 1965 A. J. HAYES 3,208,360
AGGREGATE SPREADER Filed April 30, 1962 INVENTOR. ALBERT d. H/ayss aw {M United States Patent 3,208,360 AGGREGATE SPREADER Albert .1. Hayes, RD. 1, Avonia Road, Lake City, Pa. Filed Apr. 30, 1962, Ser. No. 191,092 1 Claim. '('CI. 94-44) This invention relates to road building machinery and, more particularly, to machinery for spreading gravel, aggregate, black top material, or the like on road, driveways, and other surfaces.
Prior machines of this type were not suitable for transportation on the front of the blade of a bulldozer so that the device could be pushed along. Prior spreaders were not suitable to be pushed against the back end of trucks. The present device is actually used to propel the truck forward and, at the same time, to distribute the aggregate evenly over the ground.
It is, accordingly, an object of the present invention to provide an improved aggregate spreader.
Another object of the invention is to provide an aggregate spreader which can be used by attaching it to the blade of a bulldozer and the device used to push a dump truck.
A further object of the invention is to provide an aggregate spreader which is simple in construction, economical to manufacture, and simple and eificient in operation.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claim, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing:
FIG. 1 is a side view of an aggregate spreader supported on a bulldozer and having the front edge thereof pressed against the rear tires of a truck;
FIG. 2 is an isometric view of a part of the aggregate spreader shown in FIG. 1;
FIG. 3 is a cross sectional view taken on line 3-3 of FIG. 2;
FIG. 4 is a cross sectional view of another embodiment of the invention taken in a position similar to a view taken on line 4-4 of FIG. 3; and
FIG. 5 is an enlarged view of the top shown in FIG. 3.
Now with more particular reference to the drawing, an aggregate spreader is shown supported on the blade of a bulldozer indicated at 11. The bulldozer 11 has a blade 12 of the ordinary type which engages a rear wall 13 of the aggregate spreader 10. A hook 55 will support the spreader so that it can actually be lifted by the bulldozer.
The truck shown in FIG. 1 has a frame 14 and wheels 15 with a dump bed supported by a hydraulic lift cylinder 17 and other suitable arrangement familiar to those skilled in the art.
The aggregate spreader 10 has a hopper which is generally rectangular in plan view and has a rear wall 18, a front wall 19, and an inclined bottom wall 21. The side, front, rear, and bottom walls generally make up the hopper.
The bottom wall 21 which terminates near and is spaced ahead of the lower edge of the gear wall thereof defines a groove between the lower edge of the bottom wall 21 and the rear wall 13. The amount of opening defined by this groove is determined by a sliding door 24 which is in the form of a plate which is received in a channel track 25 at each side of the spreader 10.
The sliding door 24 may be carried by a roller attached to the outer edge which runs in the track 25 to carry the door backward and forward. The sliding door has a rack 27 fixed thereto and extending upwardly from the upper side. This rack extends through a slot 28 in an upper leg 29 of the track 25.
A lever 30 is pivoted to a side 20 and 31 and it has gear teeth on a sector 32 on its lower end. These gear teeth engage the teeth on the rack 27. Thus, when the lever 30 is swung forward, it will rock about the pivot 31 and force the door 24 rearward to closed position as shown in FIG. 2. When the lever 39 is swung rearward, it will force the door 24 forward and increase the size of the crack between the rear wall 18 and the bottom. Thus, the aggregate will be distributed evenly over the surface over which the device travels.
Wheels 33 support the aggregate spreader 10 so that it can be moved over the ground. In addition, front wheels 34 support the front edge so that it can be moved. A roller 35 extends outward from the front and is supported on brackets 36 so that the bulldozer 11 can engage the wheels of the truck by means of these rollers and push it forward.
In operation, the bulldozer can be driven up to the truck and the roller 35 brought into engagement with the rear wheels 15. The dump bed can then be raised to cause material from the truck load to fill the spreader as desired. The lever 30 can rock forward to open the door 24 the desired amount. As the bulldozer pushes the truck forward, the aggregate will be spread to the desired thickness.
Wings 40 extends laterally from the rear wall 18 and may be welded or bolted to the wall 18 so that aggregate can be spread at the sides of the wall 18.
If it is desired to decrease the elfective width of the aggregate spreader, plates 50 indicated in phantom lines in FIG. 3 can be rested on the sliding door 24 and inclined upward with a hook 51 hooked over the side 20. In this position, one edge of the plate 50 would be secured and rest against the inner edge of the wall 18 while the other edge would incline upwardly and forwardly and rest on the wall 21.
In the embodiment of the invention shown in FIG. 4, a sliding door 124 has a rack section 127 welded to the central part thereof intermediate sides and below an inclined wall 121. A shaft 136 is fixed to a gear 131 and a handle 130 is attached to the end of shaft 136 so that gear 131 can be rotated to move the sliding door 124 backward or forward. The sides 120, rear wall 118, and inclined wall 121 are similar in construction to those shown in FIG. 3.
The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claim.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
An aggregate spreader for use in combination with a bulldozer having a blade comprising a container having wheels at each side thereof adjacent the front thereof,
said container having a rear wall adapted to be generally coextensive with a part of said blade and extending from top to bottom thereof,
downwardly facing hooks fixed to the top of said rear wall,
said hooks having a downwardly extending part extending generally parallel to said rear wall and spaced therefrom and defining a space therebetween and being adapted to receive the upper edge of said blade in said space whereby said container is attached to said blade with the bottom edge of said blade engaging said rear wall whereby said spreader can be lifted and said spreader can be removed from said blade by moving said blade downwardly relative to said rear wall,
a roller attached to a front wall of said container to engage the tires of a truck,
said container having an open bottom,
a sliding door,
means to support said sliding door below said open bottom to form a closure therefor,
a rack attached to said door at an intermediate part thereof between the sides of said container and disposed forward of said front wall,
a gear engaging said rack and a shaft extending laterally therefrom,
a lever attached to said gear for rotating it to move said sliding door forwardly and rearwardly to open and close said open bottom,
laterally extending wings attached to said rear wall of said container with a lower edge generally parallel to said rear wall and extending outwardly therefrom for spreading aggregate,
and additional wheels attached to said container forward of said first mentioned wheels.
