UNITED STATES FRANKLIN E. ARNDT, 0F GALION, OHIO, ASSIGN'OR TO THE GALION PATENT IRON WORKS it MFG. 00., OF'GALION OHIO, A CORPORATION OF OHIO.

STONE DISTRIBUTOR SPREADER.

Application filed February 3, 1921. Serial No. 442,231.

To all whom it may concern:

Be it known that I, FRANKLIN E. ARNDT, a citizen of the United States, residing at Galion, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Stone Distributors and Spreaders, of which the following is a specification.

This invention relates to road building machines, and particularly to machines for distributing and leveling road metal such as broken stone, gravel, or other broken or comminuted materials on roadways.

The general object of the invention is to provide a broken stone distributor for roadways of a very simple construction and which is adapted to be drawn by and behind a truck and to receive the broken stone or other material from the truck and discharge it onto the roadway in a layer.

A further object is to provide a construction of this character wherein the stone so distributed is levelled upon the roadway, and wherein this levelling is accomplished by raising or loweringthe hopper relative to the shoes upon which the hopper moves.

, And a further object is to provide a construction of this character wherein the thick- I ness of the layer of stone laid down may be varied from one end of the hopper to the other if desired. 1

Another object is to provide'wa device of this character which is simple in construction, which may be cheaply made, and which will be thoroughly effective for the purpose designed.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure l is a rear elevation of my distributor;

Figure 2 is a section on the line 2-2 of Figure 1 looking in the direction of the arrows; and

Figure 3 is a section on the line 33 of Figure 1 looking in the direction of the arrows;

Figure 4 is an end elevation of another embodiment of my invention, showing the hopper-shaped body in one of its adjusted positions;

Figure 5 is a section on the line 55 of Figure 4;

guides 17 which are outwardly Figure 6 is a section on the line 6-6 of F lgure 1;

Figure 7 is a section on the line 77 of Figure 1.

Referring to these drawings, 10 designates the hoppershaped body or container having downwardly converging forward and rear walls 11, these rear walls having attached thereto at their upper ends the angle iron frame 12, the horizontal flanges of which pro ect outward, as illustrated in Figure 1. The forward and rear walls 11 extend downward toward each other, but the end walls 13 extend straight downward. The forward and rear walls terminate in spaced relation to each other to provide a downwardly dis charging mouth 14.

For the purpose of supporting the hopper-shaped body 10 and'raisingor lowering thishopper-shaped body, I mount upon the pro ect1ng flanges of the angle iron 12 at opposite ends of the hopper-shaped body the vertically disposed screws 15 having crank handles 16 whereby the screws may be rotated. Attached to the end walls 13 are bent at their mlddle portions to receive the vertically disposed shanks 18. Each shank 18 at its upper end is angularly bent, as at 19, and is screw-threaded for the passage of the screw 15 so that as the screw is rotated in one direction or the other,the shank 18 is raised or lowered. These shanks at their lower ends are attached to or connected to shoes or runners 20 which are disposed flat upon the ground in the manner of sled runners and are upwardly turned at their forward ends. These shanks 18 are attached to the shoes midway of the width of the shoes and slightly nearer the rear ends of the shoes than the forward ends thereof. The forward, upwardly turned ends of the shoes are perforated or otherwise formed for engagement with draft chains 21 which extend forward and are connected to a truck by any suitable means. The body of the truck is designated A and this truckbody is shown as extending slightly over the front wall of the hopper and'as being tilted downward so as to discharge materials into the hopper.

The operation of this invention will be obvious from what has gone before. The truck body A discharges broken stone, gravel, slag, sand, or any other suitable mawall of the hopper.

terial of a more or less comminuted character into the hopper-shaped body 10 and this material is discharged through the mouth 14 onto the roadway, as the hopper-shaped body is being dragged along by the truck. As the hopper-shaped body moves along, discharging the load of stone onto the ground, the rear wall of the hopper-shaped body acts as a scraper, leveling off the stone so as to give a layer of even thickness along the whole width of the roadway or for a width depending upon the transverse length of the hopper. If a relatively thin layer of stone or material is desired, the adjusting screws 15 are turned so as to draw the shanks 18 upward, thus bringing the runners close to the lower edges of the forward and rear walls of the hopper. If a thicker layer is desired, the screws 15 are turned so as to raise the hopper-shaped body. This will, of course, obviously vary the thickness of material deposited upon the road. It is also possible with my construction to adjust one of the runners or shoes a greater distance from the open bottom of the hopper than the other runner or shoe so as to thus cause the layer of material deposited by the distributor to be slightly less in thickness at one end of the hopper than at the other. This is particularly valuable where it is desired that the crown of the road shall have a greater thickness of broken stone laid thereon than the margins of the road. Of course. the hopper-shaped body may have any desired length, this length depending upon the width of the truck body A to, which it is connected.

It will also be noted that the height of the hopper-shaped body relative to the shoes may be regulated from time to time so as to gradually increase the thickness of the material distributed from the hopper or decrease the thickness of this material. This is useful where grades are being changed or slight hollows have'to be filled up. It will be seen, of course, that this causes the layer of material to be of uniform depth and width if desired, or a slight difference in depth may be secured. I

In Figures 4; to 7, I illustrate another embodiment of my invention, in which the hopper body is not only mounted for vertical movement but mounted for tilting movement as well, the object being to so tilt the body that material discharged from the body of the dumping wagon will not be discharged over the rear wall or the'front In this construction, the hopper body 22 has approximately the same form as the hopper body 11 previously described, This hopper body is braced and framed by means of the corner angle irons 23 and the longitudinal angle irons 24: and

As illustrated in Figure 6, there is mounted upon each end of the hopper body a casting 26 which is pivotally supported upon the end wall of the hopper body by means of a pivot bolt 27 passing through a bushing 28 in the side wall. This casting is formed to provide a vertically extending guide channel 29 and to provide laterally projecting cars 30 which rest against the end wall of the hopper, these ears being preferably arcuate in form and formed to provide arcuate slots 31, these slots extending downwardly and laterally in opposite directions. Passing through these slots are the bolts 32. A reinforcing plate 33 is attached to the end wall of the hopper behind the casting 26, through which plate! the bolts 32 pass. The casting 26'is formed in two sections. The front section 34 of this casting is conterminous at its lower end with the lower end of the body of the casting but does not extend up as high as the upper end of the casting 26 and at its upper end is angularly extended, as at 35. This section 34 is held to the body of the casting 26 by means of. cap screws 37. The projecting portion 35 is interiorly screwthreaded for engagement by an adjusting screw 38. The shank 39 of the runner 40 extends upward through the recess 29 forming the guideway in casting 26 and is held in this recessby the section 34, and at its upper endis angularly bent, as at 39 The screw 38 extends through this angularly bent termination of the shank 39 and is swivelled in this angularly bent end of the shank by means of the collars ll having pins which pass through the screw-threaded rod 38. It will be obvious that when this screw-threaded rod is turned, the casting 26 with the hopper will be raised or lowered relative to the runner 40.

The bolts 27 constitute trunnions upon which the hopper may swing, the range of this tilting movement of the hopper being limited by'the length of the slots 31. Thus the hopper, by rotating the screws'38, may be raised or lowered and by loosening the nuts 33, the hopper may be swung upon its pivot bolts or trunnio'ns 27 to any desired angular position and then again fastened by the nuts 33.

The purpose of this is to permit the hopper to be turned so as to cause the rear wall thereof to approach the wagon body A or to cause the upper end of the front wall to approach the body A, or in other words to adjust the hopper so that all of the road metal or other material discharging from the wagon body A shall be discharged into the hopper and not over the rear wall of the hopper or in advance of the front wall thereof. It is obvious that if the body A of the dumping wagon is relatively high and relatively large, that there will be a trend ency of the material to shoot out beyond the hopper,-but by tilting the hopper so as to carry the rear wall upward toward the dismovement of the wagon body and at the same time so disposing the hopper that all of the material discharged from the wagon body will be caught in the hopper.

Of course, the hopper shown inFigures 4: to 7 is also provided with draft means whereby it may be drawn with the wagon or truck, and I have illustrated the up-turned ends of the runners 40 as being connected by a transverse angle iron 42 having draft chains 43 connected to the runners by means of clevises 44.
