DUMPING-WAGON.

vide in a dumping wagon means for auto" matically removing the end or tail-board as the wagon is dumped. I

A. still further object of the invention is to )rovide a gearing mechanism associated Wit the wagon body .nd with the frame or running gear, which maybe operated in one direction for moving the Wagon body to a dumping position and operated in an opposite direction for moving the wagon from a substantially dumped position back to its original position on the frame or running gear.

ln carrying out the objects of the invention, a running gear is provided formed with a supporting frame. On this supporting frame is arranged a plurality of rollers q designed to support a body which may be "dumped. This body is adapted to be actualt) b ll

ated by a rack pivotally connected therewitln which in turn is moved by suitable gearing, the gearing being arranged with crank engaging members which when oper-. ated in opposite directions will move the rack and wagon body in opposite directions, namely, to a dumped position and from the dumped position to the original working position. Connected" with. the wagon body and the frame is an arrangement of levers connected with the tailboard of the wagon body so as to automatically raise the tail-board simultaneously with the dumping ofthe body.

A practical embodiment of the invention is represented in the accompanying drawings forming apart of this specification, in whiol'i similar characters of reference indicate eerresponding parts in all the views.

Figure 1 is ,a side view of an embodiment ofthe invention; Fig. 2 is a side view on an erllarged scale of a wagon embodying the iHLVQDtlOII; Fig. 3 is a top plan view Specification of Letters Patent. Patented llllalr. Sil lll'l lllillt I Apprtcation filed may 10, 1913. Serial No. 766,747.

of the wagon frame and running gear shown in Fig. 2; Fig. l is a side view of the structure shown in Fig. 3, the rear axle and bracing links being removed; Fig. 5 is an enlarged detail fragmentary sectional view disclosing the body moving rack and the gearing therefor; and Fig. 6 is an enlarged detail fragmentary side view of one of the rear supporting springs and the links associated therewith and with the rear axle.

Referring to the accompanying drawings by numerals, 1 indicates an automobile structure provided with suitable steering apparatus, engines, and the like. lhe engine and driving mechanism of the auto mobile structure is designed to drive one or more chains 2 which engage suitable sprockets 3 arranged on the front axle a of the dumping wagon 5. The traction wheels mounted on axle 4 are connected therewith so as to act as drivers in the usual manner. In order to provide a proper steering of the device, axle l is designed to co act with a suitable turntable or fifth wheel 6, supporting the front part of the dumping wagon. The rear axle 7 of the dumping wagon 5 is provided with any kind of traction wheels 8. Mounted on the turntable 6 are a plurality of longitudinally arranged beams 9 which, together with the front beam 9 and any desired number of auxiliary cross beams, forms a frame. The rear end of each of the beams 9 carries a .bracket 10 (Fig. 6) which accommodates pins 11 and 12. The pins 11 and 12 act as journal pins for links 13' and 14:, which in turn are pivotally connected by pins 15 and 16 with a suitable clamp 17 held in placed by bolts, or otherwise on axle 7. The clamp 17 is formed with squared portions to properly fit the squared shaft 7, but it will be perfectly evident that if shaft 7 was of any shape the clamp could be made of a corresponding shape. A spring 18 has one end arranged to pivotally engage the journal pin 12 on bracket 10, while the opposite end loosely presses against axle 7. The center of the spring is clamped to the beam 9 by suitable substantially U-shaped clamps 19 and cross bars 20. Nuts of any desired kind are provided for members 19-so as to firmly clamp bars 20 against the spring which presses against the filling block 21., and block 21 in turn rests against plate :22 which carries the brackets 10. Plate 22 is connected in any desired way with the merely .,'is a load thereon, a rack i a dumped full lines and ,31, shown. in Fig 3,

beam 9. In this way a resilient support is provided for the rear of the wagon 5, while any usuai'or preferred form of spring may be with the turntable 6 at the forward part of the wagon. The arrangement of the links 13 and 14: co-acts with the brackets '10 and clamp 17 and with the spring, so that when the rear of the wagon is moved up and down, the axle 7 will be normally held in proper p osition and prevented from turning.

. Arranged on each of the beams 9 are a plurality of brackets 23 carrying rollers 24 which act as antifriction supporting means for "the body supporting beams 25 forming part of ihe body 26. The body supporting means are designed to freely slide to the rear and thus allow the wagon to) dump, as shown in Fig. 2, whenever desired. Rigidly connected with the two side beams 25 are-stops or hook members 27, designed engage projections 28 and 29 arrangedfiii the beams 9. The projections 28 and 29 are the ends of bar 30 extending beyond the side beams 9, as clearly shown in Fig. 3. If desired, a central hook, or a number of central hooks, could be used without departing from the spirit of the invention, as; the same easily operaie and correctly engage the bar 30. In order chat the body 26 may be moved back and. forth as desired even when there i 31* is pivoted at 32 to a suitable bracketv mounted on the body 26. Freferably fihere are two of these racks so as'to cause a more even movement of the body 26. The racks 31 are designed to engage a pinion 34 rigidly secured to shaft Theshaft 35 has also rigidly secured thereto gears 36 near each end designed to mesh with gears 37 ed 39 and 4c, respectively.

The g. o: and are rigidly secured to the Sb? 1, while gears 88 and 46 are rigidly secured to shaft 452. Shafts 41 and 4:2

extend beyond the outside beam 9 on each side of the wagon so as to receive clutch heads The clutch head 43 on shaft 42 is designed to rotate shaft 42 in one direction when a crank 44 is applied thereto so as to cause the body 26 to move back from position to a position shown in in Fig. 2; en it is ,esired to cause the body 26 to dump, crank 44 is moved over to either of the clutch heads 43 on shaft 41 and rotated, After the wagon b0 26 has been moved back to its working position, as shown in Fig. 2, a. locking pin 45 may be used and may be passed through a projection 46 at the forward end of the body 26 and through a suitable bracket l7 (Fig. 2). In addition to these securing means suitable books 48 may be used. The

Chocks 48 are pivot-ally connected with any part of the running gear, as for instance cross beam 9', and are designed to engage suitable pins arranged on the wagon body 26. In moving the wagon body 5 from the dumped position back to the working positioIu-blie forward end is designed to be stopped by the cross beam 10 and also by suitable stops 49 associated with the cross beam 10.

In order that the end board or tail-board shall automatically open or be removed, the same is pivotally connected at 51 to an arm 52 on each side of the wagon. The arms 52 are pivotally connected at 53 to the wagon and have pivotally connected intermediate their length links 54. Pivotally connected with the links 54 are connecting rods 55, in turn pivotally connected at 56 to the outside beams 9. In order to hold the tail-board properly in position at the lower end, a book 57 may be used which, or course, is to be unfastened previous to the dumping of the Wagon. As the body 26 moves to the rear the links 54 and rod gradually assume the position shown in dotted linesin Fig. 2, but do not act upon the tail-board 50 until they have formed a straight line, whereupon they will prevent any further bodily rearward movement of the arms 52 that will holdthe upper part against further moi ement, and as the lower part continues to move that the tail-board will be raised as shown in dotted lines in Fig. 2. In order that this action may be carried out without undue friction, anti-friction rollers 58 may be arranged at the rear of the wagon body 26 for guiding the tail-board 50 in its movement. When the wagon body 26 is moved back to its original position the tail-board will automatically move to its correct position so that the book 57 may be again placed in position manually.

Having thus described my invention I claim as new and desire to secure by Letters Patent In a dumping wagon of the class described, a running gear provided with a supporting frame, a body adapted to be dumped therefrom, said body being formed with a tail board, a pair of arms pivotally connected at one end with said body and at the other end with the upper ed e of said tail board, means for locking the lower end of said tail board in place while said body is on said frame, a link pivotally connected to each of said arms substantially central thereof and extending normal thereto when the body is on said frame, a rod pivotally connected and to said supporting frame, said rods being connected with said supporting frame in front of said arms, whereby when said body is dumped the tail board and the upper end of said arms will move therewith until said links and said rods move to a the result will be.
