DUMPlNG-GAR.

SPECIFICATION forming part of Letters Patent No. 296,088, dated April 1, 1884.

Application filed August 30, 1883. (N model.)

marked thereon, which form a part of this specification.

My present improvements relate to a device for holding the car-bed in a horizontal I posiof the draw-bar withthe truck and its central draft timber,to the same in relation to a hinged platform on the truck for the operator,

to means for tilting or dumping the car, and

to other novelties,which will fully appear from the following description.

Figure 1 represents aside view of a car made in accordance with my present improvements; Fig. 2, a top view of the truck-frame, Fig. 3,

a top view of the frame of the car-bed; Fig. 4,

an end view of the car-body, and a cross-section of the truck in the line a: w of Fig. 1; and

Figs. 5 and 5 to are details.

My present improvements are designed more especially for a four-wheeled dumpingcar.

A is the car-body, and B the truck. I will first describe the devices 0 0 for holding the car-bed in position and. their action. Each of them is hung on apivot or bolt, d,and

. H is in the form of a stirrup, (see Fig; 9,) and has a single cross-bar, e.

Each is connected, substantially as shown, to a short chain or rod,

1 o f,whose other end is connected to a long chain or rod, 9, this latter rod or chain serving thus to connect f with f, so that both stirrups on the same side of the car shallbe simultaneously operated by the same movement of the handlever h. i These stirrups G G are pivoted on the inside of the sill of the car body or frame,

and the rods or chains f 9 also work on the inside of the same sill. 4

D D are fixed catches for the stirrups G, and

p they are bolted to the truck-frame, as seen.

That portion, 6, which engages with the stirrup when the latter is in its vertical position tapers or inclines at both sides and at the top, the under side, however, being straight, as seen. By these means,when the car-bed is in a horizontal position, and the hand-lever h is released or free, the stirrups drop by their own weight to their vertical positions, and in so doing the loop of each stirrup embraces and receives the portion i of the catch. The carbody is thus firmly held to its position, because the stirrups cannot ride off from these catches. The cross-bar 6 acts as a relief to the stirrup as the car is tilted. The stirrups being released on one side of the car, and the car being tilted, the cross-bar of the stirrups on the opposite side of the car strikes in their downward movement againstthe inclines on the upper side of the catches D D, and thus rides down these inclines and frees the stirrups from the catches. The stirrups, it will be noticed, swing lengthwise of the car, and both thecatches D have their tapering ends in the same direction or toward that end of the car from which the stirrups are worked.

The latching and nnlatching devices for the swing-doors K are as follows: Attached to the outside of the doors are slotted pieces Z, the

slots m of which are adapted to receive the notched end a of a gravitating lever-latch, 0, which is pivoted at or on the under side of the outside sill, o, of the car-bed. This notch 19 the truck, and not to the car-body, and its ad jacent parts are as follows: A central draft timber, r, extends from end to end of the car, and to its ends are boltedblocks 8, upon which rests and slides the draw-bar; and t is a straddle-block or yoke through which this drawbar works, and on top of this yoke t is a hinged platform, a, for the operator to stand upon when dumping the car, pins or bars 1; projectj to act on the rocker.

ing above its surface to brace his feet, and to prevent the operator from slipping or being thrown off as the car dumps. The platform may be raised vertically out of the way, when not in use, by a cord or chain, w, and when so raised it protects, in part, the mechanism by which the dumping is effected, and is not in the way of the brakeman in coupling or uncoupling the cars. The object of the block 8 is mainly to give sufficient elevation or height to the draw-bar, and it thus incidentally, also, affords a bed or foundation for the yoke 15, and thus brings the platform to a proper height for the workman. The platform, being on the truck, andnot on the car frame or floor, does not tilt when the car is dumped. The drawbar, also, being on the truck, and not on the car, is not turned partly over when dumping, but preserves always its true position for coupling, so that if the platform should occupy its raised position and the bodies of two of my cars should both be in their tilted positions, yet they could be coupled together just as easily as if they were not tilted. The platform may be always kept raised, when not in use, and held up by any appropriate cord, chain, or latch, and when so raised it partially conceals and protects the tilting gears or wheels.

The mechanism for lifting and dumping is as follows: A block, at, is bolted (as seen in Fig. 4) to each of the outside stringers, y, these blocks also resting on the end beam, 1. The object of these blocks is to afford sufficient height for the fulcrum of a long lever, 2, (one on each block,) and which, when pulled by the chain 3, which is fastened to the other end of each lever, serves to push up the rocker 4 by means of the rod or link lever 5, which is pivoted to the rocker, and also to the long lever 2. These levers 2, being long and fulcrumed at one end, and operated by the chain at their other ends, have a powerful leverage This chain is a linked one, and it passes from the end of one of the levers 2 up and around a toothed wheel, 6, on the end of the car-body, thence down and under a toothed wheel, 7, on the axis of the large gear-wheel 8, thence up and over the toothed wheel9 on the car-body, and thence downward and crossing itself to the extremity of the other long lever 2. It will be understood that the teeth or pins on the small wheels 6, 7, and 9 enter the links of the chain,- and the chain is taut enough to have both levers 2 2 act in unison, so that when one link 5 is pushing one side of the rocker up the other one is pulling the opposite side of the rocker down. Ahandcrank, a serves to turn a cog-wheel, b which operates the large. gear-wheel 8, this gear serving to multiply power. A large round pin, 10, projects upward from the central draft-timber, r, and into and through an opening in the metal arch 11 of the rocker. Small round or conical pins 12 project upward from the plates 13 on the end beams, 1, the metal arch 13 being provided with suitable holes to receive them. All these pins and holes are to prevent any sidewise sliding of the rocker, and the smaller ones also keep the body on the rocker-sill in case of concussion during or after dumping. The piece or block 14 extends centrally on the truck from rocker to rocker, and prevents endwise shifting of the bed. It is bolted at each end, as seen, to the draft-timber 1", thus giving the whole strength of both in holding the rocker-sill. The shallow stringers 15 are for giving strength to the floor, and they are so located that when the dumping takes place they may come j ust inside of or bear against the inside of the outside sills of the truck and prevent therbed dropping off the truck. In other words, the outside of stringer 15 would comeinside of the sill? ,which sill would thus form an absolute barrier against any further lateral movement of the car-body. The gears 6 7 8 9 and the chain 3 are on the outside of the end of the carthat is, outside of the end sill or beam. The draft-timber r at'its ends has its top reduced or cut away, as seen at 1", and on part of such reduced surface is secured. the metal plate 1", provided with a metal pin or projection, r adapted to enter a central hole in the metal arch ll of the rocker. The blocks 3 s are also placed on a part of these reduced ends and this leaves aspace between the blocks and the unreduced portion of the draft-timber, within which the rocker works. It will thus be seen that the rockers are positively prevented from any shifting in a direction lengthwise of the car, and the car cannot shift endwise, as the rocker is practically held between two wallsone in front and one behind it.

The plate 1" is, as seen, in continuous line with the two plates 13 13, the three plates constituting the straight rocker-bed. To make .these plates 13 13 andr all in one piece would be objectionable, as liable to be bent or broken,

and, moreover, as the projection r should be integral with or firmly connected to the center of this metal bed, it is safer and better that its plate or horizontal part 1 should not be too long. The draft-timber r, it will be seen, is firmly bolted through its entire or unreduced thickness to the top of the center bolster, a (see Fig. 7,) thus giving great strength and solidity, and contributing largely to support the load. In the truck-frame are stringers Z Z, placed inside of the outer sills, 3 y, and be tween them and the car center; they are placed against the blocks as w, and are let into the truck-bolsters, as shown, and are firmly bolted to and through these bolsters. At the center of the car these stringers are of about equal other, and bolted to the longer one, so as to leave at its ends the rabbets or reduced ends, as at r.

I claim a 1. In combination, the stirrups G, as made with the single cross-bar e, and hung onthe sills of the car bed to swing in directions lengthwise of the car, the tapering catches D, fixed on the car-truck, and having their under sides straight, and the connections f and g and hand-lever h, all substantially as and for the purpose set forth.

2. The combination, substantiallyas shown and described, of the central draft-timber,r, on the truck, the block 8 thereon,the draw-bar resting on said block, and the straddle-block or yoke t, within which the draw-bar works, the draft-timber block and yoke being bolted together. p

3. In combination, the draft-timber r on the truck-block s, yoke 15, and a platform, a, hinged above said yoke, as and for the purpose set forth.

4. In combination with the blocks 2;, bolted to the outside sills, y, of the truck, and resting on its end beam,1, the lovers 2, chain 3, linklevers 5, rocker 4, and the system of toothed gears on the car-body, the combination operating to tilt thebody by pushing either of the link-levers 5 upward against the rocker.

5. In combination with the rockers of a dump-ear, the central draft-timber, r, on the truck-frame, made, as described, with reduced ends, on which the rockers bear, and with a greater height or thickness between the rockers, as and forthe purposes set forth.

6. In a four-wheeled side-dumping car, the combination, with a center bolster, of, of a central draft-timber, r, centrally supported on and bolted at its center to the center of said bolster, said draft-timber being at its ends let into and secured to the rocker-bolsters, and forming a portion of the bed for the rockers.

7. In combination, the levers 2, links 5, chain 3, toothed gears 6 and 9 on the car-body, large gear-wheel 8, having the toothed gear 7 on its axis, and driving-gear If, these parts being arranged for joint. operation substantially as and for the purposes set forth.
