CALVIN B. DEYO, OF CALUME'I, ILLINOIS.

DUMP-WAGON.

SPECIFICATION forming part of Letters Patent No. 502,249, dated July 25, 1893.

Application iiled May 25, 1892. Serial No. 434,309. (No model.)

To all whom it may concern:

Be it known that I, CALVIN B. DEYo, a citizen of the United States, residing at Calumet, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Wagons; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to dump Wagons, and consists of the use in connection with the running gear of an ordinary wagon of a semi-cylindrical metal box, pivoted by means of a trunnion at each end in blocks carried by the holsters of the wagon, together with means for securing the box from rotating, and means for rotating the box in order to dump the load.

In the accompanying drawings, Figure l shows a plan view of my improved wagon. Fig. 2 is a transverse vertical section on the line 2, 2, of Fig. l. Fig. 3 is a longitudinal vertical section on the line 3, 3, of Fig. l. Fig. 4. is a longitudinal vertical section on the line 4, 4, of Fig. 1. Fig. 5 is an elevation of the supporting block carried by the rearward bolster of the wagon. Fig. 6 is a detail of the lever for dumping the box, and Fig. 7 is a detail of the crank which may be used for the same purpose.

A hollow semi-cylindrical box, A, having vertical ends, a, a', is hung between the bol-V sters of an ordinary wagon, the end pieces being provided with trunnions, E, E', which engage in sockets in the blocks, D, D', which are adapted to rest upon the bolsters, b2, c, and which have their ends grooved so as to slide upon the bolster stakes, h3, c. The trunnions, E, E', are preferably located below the center of the circle, of which the cylindrical part of the box is an arc. A large gear- Wheel, F, is rigidly fixed upon the trunnion, E, between the end of the box, A, and the riser block, D. A small geared pinion, G, is keyed upon a stem which is journaled in a box fixed upon the top of the block, D, in such position that the wheel, G, meshes with the Wheel, F. The stem of the wheel, G, projects forwardly, as shown, at g, and its end is angular and is adapted to receive the socket of the crank, H. The bolt, or locking rod, L, rests upon the foot board of the wagon, b, and is adapted to slide between the teeth of the wheel, F. The forward end of the locking bar, L, is pivotally fastened to a swinging lever, L', which is pivoted to the foot board, b. The lever, L', is so located that it can be controlled by the foot of the driver. The sides of the box, A, are reinforced by pieces of angle iron, P, P, riveted along the upper edge of the box. The trunnion, E', terminates in a ball, e, which'fits within a socket adapted to receive it, so as to form a ball and socket joint, whereby cramping is prevented should the wagon stand on uneven ground. Friction rollers, N. N, are placed in the blocks, D, D', so as to receive theimpact of the ends of the box, A, should the latter be shifted forward or backward by the uneven surface of the ground. These rollers, N, N, are set into apertures in the blocks, D, D', so as to project slightly beyond their surfaces, and are carried by bolts, n, fn, projecting inwardly from the bottom of the block.

An ordinary wagon is adjusted to receive my improved dumping box by changing the length of the reach, K. Most Wagons are made with an adjustable reach. If not so constructed, the reach is easily modified in this particular.

The drivers seat, b', block, D.

The box is adapted to be dumped ordinais carried by the rily by means of the crank, H, itting upon l the stern, g, of the wheel, G. I prefer to so proportion the two pinions that three turns of this crank will dump the load. It' quicker action is desired the hand lever, M, may be used. This lever is forked at one end so as to tit upon the trunnion,E, between the wheel, F, and the end of the wagon box. The lever is provided with a stud, m, which is adapted to engage the apertures, m', 'rn/,in the end, a, of the wagon box. When in position, the handle end of the lever, M, projects above the box, and is in position to be grasped by the driver as he stands upon the foot-board, b.

It will be seen that the box, A, may be completely rotated if desired. For convenience IGC) in driving out of pits or other` cramped positions, the box may be turned upon its side, and in this position the forward Wheels, O, O, of the Wagon may be cramped, as shown in Fig. 2, so as to touch the reach, K, Without injury to the boX--a consideration it has been heretofore found Very diliicult to secure in a duinp wagon.

rIhe box, A, may be made of sheet metal, either iron or steel.

I claim- In a dump-wagon the combination with the holsters and standards of a Wagon, of a semicylindrical body adapted to swing between the forward and rearward holsters, tru unions projecting from the ends of thebody, pillowor riser-b1oeks carried by the bolsters and having sockets or bearings for the trunnions, one of the trunnions and its socket being in the forni of a ball and socket joint, whereby the Wagon is adapted to adjust itself to uneven ground, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
