To all whom it may concern.-

Be it known that I, DANIEL OBRIEmof Brooklyn, in the county of Kings and State of New York, have invented an Improvementin Dumping-Oars, of which the following is a specification:

The object of this invention is to simplify the construction of the dumping-cars used in conveying earth, gravel, &c., from. one place to another, thereby avoiding the constant repairs, detention, and expenses consequent upon the use of the ordinary dumping'cars.

In the drawing, Figure l is a vertical section transversely of the car. Fig. 2 is a sectional elevation of the same at the line a: w and Fig. 3 is a plan view of the latch-lever detached.

The oblong frame a rests upon the journalboxes or bearings b of the axles 0. d are the car-wheels of ordinary character. The lower parts b ofthe boxes or bearin gs are attached by bolts passing through slots made transversely of the box, (see inverted plan, Fig. 4,) so that by slackening these bolts the box 6 can he slipped laterally from beneath the journal sufficiently for theinsertion of oil' and cottonwaste into the cavity provided in such box, after which the box is slipped back and held to its place. This avoids the risk of loosening nuts and bolts which now exists. The drawbeam d of the car runs through the frame a,

and its ends form the buffers of the cars. The coupling-chains e and hooks are made to hang below the buffers, and there is a clevis, f, at the end of each chain that passes above and below the stationary tongue g, and through these the coupling-pin it passes. By this construction the coupling-chain hangs below, and does not get between the buffers, and does not become injured, and the chains can be hooked together, more or less, afterthe cars have been run together, and the chains are free to draw with the clevis into any desired position. Upon the bearing-beam h the central sill k of the car-rests, and the two are hinged together at 2.

The car is of usual size and construction, except as hereafter named. The bottom m, ends n, and swinging side 0 are constructed upon the ordinary plan, except that it is preferable to have the pivots 4 upon which the side 0 swings higher up than heretoforeusual, to allow the same to openfarther, and the side pieces 5 are extended up above the pivots. -When theearth is being dumped from this car down an embankment the side 0 will generally swing open sufficiently by its own weight for the delivery of the earth but, in order to open the same wider, to clear the earth when dumped upon a level, I attach to the upper end of the side pieces 5 the chain or rope 6 passing around the pulleys 7 and 8, and attached to the frame a, so that whenthe car is dumped into the position; shown by dotted lines, Fig. 1, the rope or chain 6 will have drawn the upper end of the side piece 5 inward and swing the side away from the pile of earth dumped from the car.

In order to latch the swinging side 0 of the car, I make use of a lever, 1", upon theunder side of the car-box, pivoted at 9, and at one end there is a hook, 10, to catch the projecting metal plate 11 upon the s inging side to, so as to hold the same, and I make use of this same lever r to lock the car-box, so that it cannot tip. To effect this I make anotch in the bearing-sill s to give space for the lever r, and at one side of this notch I bolt a plate, 14, to the bearing-bar, the same having a hooked end,

beneath which the locking-lever 1" passes when it is moved to lock the swinging side of the box, thereby securing the car-box from tipping, and holding the swinging side by one movement of the lever r. This lever r is guided by a plate, a, upon the under side of the car-sill v, and there is a swinging. hook, to, at this side of the car that serves to lock the lever r, and said book may be arranged to hold the lever 1" in either position to which it may be moved, and hold it when the car is full, or hold it out of the way while the car is being dumped or replaced.

I make use of a lever-brake, w, pivoted at l6, and moving in a slot at one end of the frame a, so that the brake can be applied by pressure from the foot. There is a hanging hook, 17, (shown detachedin Fig. 5,) that can be passed under the lever to hold it up out of the way, or over-the lever to hold it and the brake down. By this construction the attendant is able to brake up one car after another with ease and rapidity.

In Fig. 6 the brake a: is shown as single, and in Fig. 2 it is represented as acting on the two brake levers x 00 so as to'apply the power to both the oar-wheels. These brakes are'not in the way of the car as it is tipped.

I claim as my inventionv l. The draw-beam d, forming also the buffers, and the stationary tongue g, in combina tion with the coupling-pin h, elevice f, and chain 6, substantially as set forth.

2. The boxof the ear, made with the swinging side 0, pivots 4, and side pieces 5, in combination with the rope or chain 6, and pulleys, substantially as and for the purposes set forth.

3. The lever r, pivoted at 9, the hook 10, and catch-plate 11, on the swinging side 0, in combination with the hooked plate 14, substantiall y as set forth.

4.. Thehook w, in combination with the lever 4*, hooks 10 and 11,'car-box, and swinging side 0, as and for the purposes set forth.

5. The brake-lever w, placed at the side of the frame a, opposite to that at which the box is dumped, and moving near its end in a slot in the frame a, in combination with the hook 17, for holding the brake-lever either up or down, as set forth.

6. The brake a: and brake-levers .00 m arranged as shown, so that the brake-levers 00 0: are operated simultaneously by the brake a2, and the parts are not in the way of the car as it is dumped, as set forth.

Signed by me this 6th day of September A. D. 1876.
