. JOHN ECCARD, OF TROY, OHIO, ASSIGNOR TO THE TROY WAGON WORKS COMPANY, OF

TROY, OHIO, A CORPORATION OF OHIO.

DUMP-WAGON.

Patented June 1, 1909.

Application filed May 29, 1908. Serial. No. 136,644.

Beit known that I, JOHN F. ECOARD, a citizen of the United States, residing at Troy, in the county; of Miami and State of Ohio, have invented certain new and useful Improvements in Dump-d agons, OfWlllC the following is a specification.

dump wagons This improvement relates to and particularly to an attachable bed. for the l closed position.

running gear of on ordinary farm wagon, and preferably bottom dump wagons.

The ob'ect is to construct the box so that it can be readily applied to the running gear of on ordinaryfarinwagon, supporting same sufficientlyhighfrom the ground to ermit the bottom. doors to open readily, and l have. so arranged thebottom doors of the wagon box that they are readily manipulatedand' the hinge connections of the inner doorsnre protected bythe formation of the wagonbed. i

In the drawing Figure 1 is a side elevation of the wagon-bed with the outer doors open. Fig. 2 is a. sectional view taken on the line m at of Fig. 1, showing however, the doors in Fig. 3 is an end View showing the doors in open position. Fig. 4 is e Y to saidboxneerthe bottom. longitudinalshaft, of, with worm gear at each.

end. thereofis shownivotally supported on detail View of thebottoin of the box showing th inner doorsend the hinge connections, looking at the bottom from underneath.

Like letters of reference indicate like parts throughout the different views. I

The box of the wagon is indicated by the .reference letter a (see Fig. 1) and is formed with open bottom and the doors are lunged saidbox, The usual rand-lever c (see Fig.

3) with the ratchet-pawl connection for opera'ti'ng the longitudinal shaft is employed.

I have shown the wagon box a, formed withfalse bolsters, a, and the guides a projecting'froni the box (see Fig l) are adapted to fit over the/bolsters on, the run ing gear of theordinnry wagon, and by men. sol the falsebolstersthe wagon box is supported sufficiently high from the ground to insure the doors, o (see Fig. 3') opening and shut ting free from interference from the ground or otherobstacles. In order to improve the dumping operation and at the" same time strengthen the construction of the wegon x box, there are employed two sets of doors The ordinary and the inner air of doors, a, are hinged shown. The hinge pivots are indicated by, the reference letter, a, and the hinges, a, are of angular she e, so that when the He s, c, are opened, t e hinges' as well as t e hinge pivots, are located well within the protection of the brace or support, a.

From on examination of Fig.2 it, is apparent that the inner ends of the inner doors, (1?, ere'turned up attiie inside edges and the hinges,,o, are then bolted to the body portion of the doors, af so that in the position shown in that figure, which is closed position, there is o erfect seal for the doors, thereby avoiding t e danger of leakage of the contents and interference with the operation of the doors. I

Chain cTinnections at each end of the bed extend between the worm gear on the longiairof chains, indicated by the reference etter, b, and two separate chains, 1) and b the chain b, at its free end being connected to one outer door, and its opposing chain, 11 at its free end being fastened to the other outer door. These chains, b and I), pass over ordinary rollers, 11 secured to the inner doors mid also over rollers, I), secured to the bed of the wagon. By operating the hand lever, a, the chain, b, is raised or lowered, and the inner and outer do rs are opeiied or closed. It is apparent by this arrangement of chem connections there is a. desirable application of ower for operating these doors; There bed of the machine with a 100k thereon for thepurpose of regulating the opening of the bottom doors or throwing out of commission one pair of: doorso,s;mey be desired. if the hook of the chain, b ,is fastened within the linksof the chsins, bor b, the doors on one in Fig. 4, where one of the hinge plates is;

is s own one c rain, b sus ended from'the rotected by said support from the i tudinal shaft, a, and the doors comprising a 'I have so formed the lock side or the other of the bed may be held closed, while the operator is free to manipulate the other doors, and if it is desired to open only partially the doors, the hook of the chain, 11 will be inserted Within a link of the chain, 6, thereby the chain, 1), can only partially operate, and the doors will be operated only a corresponding amount.

My locking devices, I), pivoted to each of the outer flaps or doors and extending through fixed loops, b, on the end of the bed are especially important in this kind of machine; for it is obvious that the machine may be standing on an incline, such that the outer doors or either of them may tend to close by gravity, whereas in closing it is desirable to close the inner doors first. For this reason that it will prevent the outer doors closing until the inner ones are closed.

The shoulder, b contacting the lower part of the loop, I) will prevent the closing, of the outer doors until the inner ones reach closing position, whereupon they will strike the hooked ends, b, of the lock, thereby raising the shoulder, [1 out of normal position to clear the lower part of the loop so that the outer doors can then close. 7

Having thus described my invention, I claim:

1. In a dump w 'agon, a'bed, outwardlyopening doors secured to the sides of said bed, inwardly-opening doors hinged to the center of said bed, a pulley located on said bed vertically above each pair of outer and inner doors, a pulley on each inner door, cables connected to each outer door and extended about said bed pulloy and also about said inner door pulleys, and means connected with the inner free ends of said cables for operating same to raise and lower substantially specified.

2. In a dump wagon, the combination of a bed, outwardly o ening doors secured to the sides of said be inwardly opening doors hinged to the center of said bed, separate cables for each pair of doors comprising an inner and outer door, and a main cable connected to said door cables, supportin means for each door cable comprising a pul ey, and a pivoted latch on one door of each air, and means for supporting the free end of said latch, and means for operating said latch during the final movement of said cables, substantially as specified.

3. In a dump wagon, a bed, an arch-shaped central brace portion, vertical extensions near the lower part of said brace portion, a plurality of inner doors, the inner edges of the doors turned upwardly to conform to the extensions on the brace portion, hinges connected to the body portions of the doors, ling-e pivots connected to said hinges and located within the central brace portion, sul'istantially as specified.

4. In a dump wagon, the combination of a bed, an arch-shaped central brace portion, a plurality of inner doors, hinges connected to the body portion of each door, a reinforcing extension connecting said hinges and bracing said arch-shaped portion, hinge pivots located within said arch portion, substantially as specified.

said doors,

my hand this 26th day of May, 1908.
