` `ing mechanism by which the spreader is Patented June 6, 1933 UNITI-:D STATES CLARENCE KoLLInAY AND CLAUDE H. NABER, OF HAMBURG, NEW YORK, AssIeNORs PATENT OFFICE s, 'ro N4 an` sPREAnnRs, me., OF HAMBURG, New YORK, A CORPORATION OKNKW YORK srREADER This invention relates to an improved material spreader which 1s designed for, but not necessarily limited to, use in connection with a dumping truck wherein the spreader is adapted to receive material, such as crushed rock, which is dumped: from the truck body and to spread such material over a prepared surface.` f i One object ofthe invention is a material spreader which may be easily secured to `or detached from the body `of the truck `with which it is associated, `the means by which `such securement is effected being adaptable `forco-operation with trucks of different size.

`Afurther Objectis a spreader of the kind generally described Vwhich maybe either secured to or removed from atruck by a single ifa workman.

The invention is illustrated in the accompanying drawings in which: Figure 1 is a side elevation of the spreader as attached to a truck, the latter being indicated in dotted lines. l Figure 2 is a side elevation of the. saine from the opposite side of the truck, the body of thelatter being shown in dumping position. s

Figurel 3 is `an `end elevation ofthe same. y Figure 4 is a fragmentary view of the body of the spreader showing in detail the operatraised and lowered during attaching, adjusting or removing operations.` y

Figure 5 isa fragmentary section of the support by which one end of the spreaderis suspended from the cross bar of the truck and associated body parts, the section being taken along line 5-5 of Figure 1.

` The spreader, as illustrated, may be employed in connection with a truck of any preferred type including a body B and a chassis C, the latterbeing provided with the usual cross bar K. `It comprises a hopper H of any suitable construction, the" construction shown consisting of vertical side walls 10 and 11 and downwardly converging front and rear walls 12 and 13 respectively, allof which are `suitably secured together. A discharge opening14 is formed: in the wall`12 from which tliematerial inthe hopper H emerges as is being fed to the road. The thickness of the layer of material which is being spread Y is regulated by a door 15 which is secured to the wall 13 of the hopper and laterally coextensive therewith. ingly against the said wall by guide plates 16 which are secured to the `-wall and overlie the ends of the door. Movement ofthe door to vary the width of the discharge opening is effected by means of an operating lever 17 y which extends along one side of the hopper and has its lower end secured to a shaft 18,

the latter beingjournaled in bracket-s 19 secured to the wall 13 of the hopper. The shaft 18 carries arms 20, the outer ends of which are connected to links 21. The links 21 are pivotally connected at their other ends to an angle member 22 which is suitably secured to the door 15. Obviously, aA movement of the operating lever 17 effects a movement of thearms 20 and the movement ofthe latter effects a corresponding movement of the door 15 through the links 21.

An agitator shaft 23 is arranged in the a chain 27 to a sprocket 28 fixed on the agita-V tor shaft. Thus, upon movement of the truck the wheel 24 by virtue of its engagement with the road effects continuous rotation of the agitation shaft and this despite elevations and depressions in the road which may be The door is held slid- Tf" encountered; The wheel 24 does not support f the hopper or its contents but supports only its ownweight plus part of the weight of the forks in which it is mounted. The wheel, therefore, bears against the road with a relatively light force, which force is suflicient to drive the agitator shaft under normal operating conditions but insuflicientto compel the continued rotation of the wheel when the i said shaft is locked againsthrotation by the l wedging of material between the shaft and the walls of the hopper.

At the end adjacent the truck, the hopper Il is suspended from the cross bar K by means of a pair of supporting members 29 which are formed with arms 29a which extend beneath the body of the truck to overlie and rest upon the cross bar. Each of the supporting members 29 is also formed with a vert-ical leg 295 to which the hopper is adjustably secured. To this end, two pairs of plates 30 are suitably secured, as by welding, 'to the wall l2 of the hopper. The plates, as illustrated, extend laterally from the said wail and at the edges opposite those by which they are secured to the hopper are formed to embrace the legs 29?) of the supporting members. The plates are formed with a pair of openings 31 (Figs. 1 and 5) which register with a series ofsimilar openings 32 formed in the legs 29?). rllhe hopper H may be secured in the position to which it is adjusted by meansof pins 33 when the opening in the plates 30 have been registered with the desired pair of co-operating openings in the supporting members29. U-bolts 34 may be employed in connection with the supporting members to prevent the supporting members from sliding from the cross bar K, the said bolts co-operating with notches 35 in the arms 29a of the supporting members and being secured to brackets 3G which in turn are secured to thecross bar.

The end of the hopper remote from the truck is supported from the tail gate 37 of the truck by a cable 38 which passes overa pair of pulleys 39 suspended from lthe tail gate by hooks 40 andunder a pair of pulleys 41 and 41a secured in relativ-e staggered relation to an angle bar 42 of the hopper body. At one side of the hopper the cable 38 is secured to the angle bar 42 while at the other side it passes beneath the pulley 41a to the drum 43 of a windless 44 (Fig. 4) which is mounted between the side l1 and the front wall 12. The shaft 45 by which the drum is operated extends through the side wall 1l and carries at its outer end an operating handle 46. The drum carries at one end a ratchet wheel 47 which co-operates with a dog 48 mounted upon the side wall 1l to prevent unwinding of the cable from the drum when the hopper is supported above the road bed. At its opposite end the drum is' formed with an annular enlargement 49 which co-operates with a brake band 50. The band 50 may be contracted about the enlargement 49 by a lever 5l which is supported abovethe hopper by an arm 51a. rl`hus, when the dog 48 is released to permit unwinding of the cable 38 with consequent downward movement of the hopper the lever 5l may be operated to set the brake band and thereby prevent downward movement of the hopper ata speed suflicient to injure it.

The hopper I-I is provided with rocker bars 52, one of which is preferably secured to each side of the hopper. The said rocker bars support the hopper upon the road bed or other surface when it is not in use. They are also availed of in arranging the spreader so that it may be readily attached to a truck.

It will be apparent from Figure 1 that upon removing the U-bolts 34, if such are used, the hopper may be lowered until'it rests upon the road. During this downward movement of the hopper, the supporting members 29 are canted with the hopper away from the truck and while the arms 29a, of the supporting members may remain resting upon the cross bar K, their forward ends will be elevated above the said cross bar. Nhen the hopper occupies this position, the truck may be disconnected therefrom simply by driving it forward, it being understood, of course, that the pulleys 39 are first unhooked from the tail gate. In attaching the spreader to another truck, assuming that it remains in the position that it occupied when detached from the preceding truck in the manner just described, the other truck is backed up toward the spreader. If it is similar to the preceding truck, that is to say to the extent that the cross bar of the chassis is substantially the same height from the road bed, there will be no necessity of changing the original position of the spreader and the truck is backed toward the spreader until its cross bar passes beneath the forwardly and upwardly extending arms 29a of the supporting members. If the cross bar of the following truck is at a different elevation than that of the preceding truck, the hopper may be rocked on the rocker bars 52 and the arms 29a may be positioned to co-operate with the cross bar of the truck as it is backed toward the spreader.

In any event, after the arms 29a have been positioned over the cross bar of the truck, the pulleys 39 are hooked over the tail gate and the crank 46 of the windlass is operated to raise the hopper in the position shown in Figure l. During the upward movement of the hopper, the arms 29a of the supporting members move toward and assulne a horizontal position. The U-bolts 34 which may then be applied are ordinarily not necessary as the supporting members 29 under most conditions will, by virtue of the cable 38 and the hooked ends of the arms 29a, rest upon the cross bar in the manner desired. The said U-bolt, therefore, may or may not be utilized.

In dumping thematerial to be spread into the hopper of the spreader, the body 13 of the truck is tilted to the position shown in Figure 2, in which position the said material is fed by gravity into the hopper. During the raising of the body to this position, the hopper I-I would, unless otherwise prevented ytween the hopper and the road bed. The

truck may then proceed under its own power while feeding the material to be spreadto the hopper II and the operating mechanism associated with the hopper insures a uniform distribution of theimaterial over the prepared surface. i i Y I Due to the facility with which the spreader may be attached `to and removed from the truck it may be employed in connection with a fleet of truc-lis. It has the further advantage that its securement or removal from a truck may be effected by a single workman and without the necessity of tools.

It will be apparent that while the invention is described and illustrated in connection with a truck having a dumping body, the latter is not essential and the spreader is equally applicable to other types of trucks.
