,In the embodiment illustrated, a body is employed, comprising side walls 16 mounted onanunder frame which includes a rear axle 17 and a front axle 18, the latter being pivoted in any suitable manner. The bottom of the vehicle is in the form of a conveyor of hingedly connected slats. 19, said conveyor being movably mounted on front and rear sets of rollers 20 jo urnaled :upon the opposite inner sides ofthe side walls 16. These I front and rear sets thus constitute in effect a sectional support for the conveyer. Between the front and rear sets of rollers are located upwardly swinging gates 21 having rollers 22 journaled thereon. the gates being pivoted by suitable devices 23 at their rear ends andhaving their front ends normally resting on a cross shaft 24 provided with sprocketwheels 251 Connecting the ends of theconveyer are sprocket chains 26 that operate on the sprocket wheels and pass around other sprocket wheels 27 mounted on a shaft 28 at the front end of the body, this shaft being transversely adjustable as shown in Fi 2 in order that the slack in the chains may e taken up. Idler rollers 29 are lo cated just in rear ofthe' rear axle 17'.and slightly above the sameythese rollers constituting guides for carrying the conveyer over the top of the axle and bolster, aswill The conveyer atits rear end operates around sprocket wheels 30 secured to a shaft 31 journaled transversely of and at the rear end of the wagon body. The front-end of the eo nveyer carries the usual upstanding wall or apron 31.

With this construction, it will be evident by reference to Fig. 4 that when the apron 31 is in the front end ofthe body; the conveyer will be located longitudinally in said body, but upon its rearward movement, the rear portion of said conveyer will move from the rear set of supporting rollers around the shaft 31, beneath said rear set of rollers, and

veyer will have passed from .the front .set I of rollers and the rear portion of said conveyer moving past the gates, will move over said-front set of rollers, as'shown :in Fig. 5.

Upon the rear en'dnf theboily are located .bra ckets'32 'inwhich is journaled a suitable distributer-drnni 33, and cooperating with "this, drum is a comb ()no end of'the drumshaft 35 carries a sprocket wheel 36,

These two sprocket wheels are connected by a sprocket chain 50. As illustrated, particularly in Figs. 12,

and is provided with an internal set of teeth 51. Secured to theshaft with n therecess, is a hub 52 having pro ect1ons 53011 which .are pivoted dogs 51 that cotipe ate with the teeth 51, These dogs are urged toward the teeth by springs The usual ground wheels 56 are mounted on the rear axle 17 and clipped or otherwise secured to said wheels are driving sprocket .wheels 57. the chains being'niovable into and out of engagement with the wheels 57 accordingly as the supporting arms are raised or lowered. This will be evident a comparison of Figs. 1 and To effect the raising and lowering of the supporting arms a rock shaft 58 is employed that ektends transversely of the body, and hassecured to its ends crank arms 59 provided with olfset terminals 60 that operate against the under sides of the arms. Another angularly disposed arm 61 is secured to one end of the rock shaft, and has a link connection 6:2 with a lever 63 arranged atthe front end of the body. By operating this lever therefore, it

will-be evident that the rock shaft will he turned. and consequently the arms 59 swung raised, the offset ends (30 preferably engage behind ribs 64 on the arm sections 12 and thus maintain the arms in elevated positions.

operates, has secured to one end'a disk (1.). which carries external and internal gear wheels 36- a'nd (37, and a reciprocat'ory support .68 mounted on the adjacentpoi'tion of thevehiclebody has joui'i aled thereon, a driving gear wheel '69,located between the mesh with either or-to an intermediate position out of mesh with both. A spring (38 mounted adjacent-to. theinner end of the support 68 forces-said support rearwardlv and normally urges-the gear wheel 69 into engagement with the gear 67. Fastengal to the driving gear 69 is a ratchet wheel 70, lo-' rated on the inner side of the disk (15/. it

lever 71, is fulcruined at one end, and as shown at 72 upon the vehicle body, and has aslot 73 in its other. end in which the crank 'pin 38 of the distributing drum operates. This lever 11 furthermorehas a longitudinal 'back and forth, operating the dogs. which in turn, will operate the driving gear (39. If

the driving gear is in mesh with the larger or internal gear 66, the conveyer will be. moved rearwardly at one speed, but if said driving gear ()9 is in mesh with the smaller gear. the return movement of the conveyor will take place at a higher rate of speed than the feeding movement. Again when .the driving gear is out of mesh with both the internal and external gears, then the conveyor willbe' at a standstill;

In order to effect the above described drivenfgears 66 and 67 being shiftable into shifting operations of the driving gear. the

following mechanism is preferably employed. A lever 18 is fulcrumed on the side of the vehicle body, preferably the opposite side to that-which carries the lever (33. and a rod 79, pivoted on the lever; is pivoted to a link 80, which is connected to the reciprocating support 68; Thus upon the operation of the lever, the gear will be shifted.

Means are also provided for effecting the automatic shifting movement of the gear. 'lo'this end, a rock shaft 81 is journaled on the lower portion of the body, and has an outer crank arm 82 connected to the front, ,end of the link 80 which end is preferably downturned, as shown, in Fig. 9. The inner endof this rock shaft has another crank arm 33, whi h is bent upwardly from the journal and said conveyer, being provided with oppositely extending hooks 8-1, arranged to :haft 81 and inwardly, and has a. part- 10-- v rated below the conveyor, as shown in Figs. 1. .to raise or lower thesupporting arm. 11 hen engage the crank arm 83. The mechanism is so arranged that upon the rearward movement of the conveyer, when the front hook .84 strikes the. upwardly bent part of crank -arm 83,;the part83 will be rocked rearwardl v, thereby rocking the part8? outside of the .wagon bodyv upwardly and rearrd-ly and through its connection with S 69 from the internal driven gear 66, whereupon'the spring (58zwill carry the gear (35) into mesh \vitlrthe; external driven gear 67 so that the movement of the conveyer is automatically reversed. On the other hand, when the convcyer has-completely returned and the rear hook strikes the crank arm the driving gear 69 will be carried out of mesh with the driven gear 67 to an intermcdiate positioitout of mesh with both gears so that the travel of the conveyer will be automatically stopped. Means are also provided for automatically increasing 'the speed of the driving gear (5%) during the return movement of the conveyer and for this purpose, a rod 85 connects the lever 78 and the carrier for the dog 76,. It will thus be evident that when the driving gear ('39 is shifted out of mesh with the driven gear ()6 and into mesh with the driven gear (37, the lever 78 being moved, willcause the carrier 75 to shift away to a position fartheraway from the fulcrum T2 of the lever 71. The dogs It therefore will have-a greater amount of movement. ()n the other hand, on the reverse shifting action of the driving gear' -69, said carrier 75 will be moved toward the fulcrum, and thusthe amount of movement of the dogs will be less, with a corresponding amount of movement of the driving gear.

There are a number of advantages for this structure as shown. In the first place, the mechanism is comparatively simple, and yet sufficient driving power is secured for operating'the conveyor and the drum, regardless of the Weight of the load. This driving mechanisnris connected with both of the rear wheels, but because of the clutches, the said wheels are permitted to run at ditt'erent rates of speed in making turns and the like. The mechanism may be stopped whenever desired, but when thrown into operation, it will automatically operate to completely discharge the load, and return the' con'vever without further attention. The said cbnveyer is so arranged that the rear portion is carried above the under frame atthe'front portion of the body, so that the front axle and wheels can turn and out under the body without interference.

From the foregoing, it is thought. that the construction, operation and many advantages of the herein described invention will. be apparent tothose skilled in the art, without further description, and it will bennderstood that various changes in the size, shape, proportion, and minor details of construction. may be resorted towithout departing from the splrlt or sacrificing any of the advantages of-the invention;
