CHARLES IV. RAYMOND, OF DAYTON, OHIO.

DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 421,432, dated February 18,1890.

Application filed December 21, 1888- Serial No, 294,249- (No model.)

To all whom it may concern:

Be it known that 1, CHARLES W. RAYMOND, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in D umping Cars and Carts, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of this specification.

WVhile my invention is applicable to nearly all classes of dumping cars or carts, it is designed more particularly for tramway dumping-cars for conveying clay to pug-mills or coal to the top of inclined chutes or other dumping-point. Its novelty will be herein set forth, and distinctly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a car embodying my invention and partly in section. Fig. 2 is a corresponding view of the car tilted asin the act of dumping. Fig. 3 is a detail front elevation of the gate-latch. Fig. 4. is a detail rear elevation of the'car-body latch.

The same letters of reference are used to indicate identical parts in all the figures.

The truck A of the can maybe of the usual or any suitable construction, and it has upon each side a journal-standard B, to which, by means of trunnions O, the car-body D is hung. The car-body is hung sufficiently high above the truck to give the proper inclination in dumping; and when in a horizontal ornornial position its rear cross-timber E rests upon a coincident timber or bolsterF upon the truck. A spring or weighted latch G, Figs. 1, 2, and i, is pivoted to the truck byjournals orboxes a and engages with a catch b, secured to the car-body-in this instance to the timber E and serves to hold the car-body locked in its horizontal position. A tripping arm c,-attached to or integral with the latch G, extends along one side of the truck, and is in this instance confined in a guide (Z and provided with the downwardly-bent elbow c and grasping-handle f.

The end-gate II is hung, as at g, in the usual or any suitable manner-in this instance by strap-hinges-upon a rod extending acrossuthe top of the ear-body, and it is held locked, when the car-body is horizontahby a pendent catch it, engaged by a spring or weighted latch I, Figs. 1, 2, and 3, pivoted to the under side of the car-body, as at 2', and provided with a downward and rearwardly extending tripping-arm j, whose lower end is in close proximity to the forward crosstimber J of the truck.

One of the principal features of my invention consists in so constructing and hanging the car-body that when loaded its center of gravity will be on the dumping side of its pivotal support and when empty it will be on the opposite side of said support, so that when the latch which holds the loaded body in a horizontal position is released the body will tilt to dump its lead, and when emptied will automatically reset itself to a horizontal posit on. This result maybe accomplished ina variety of ways by so constructing and arranging the pivoted car-body that it is heavier on its side opposite the dumping side, but has the greater part of its carrying-space on the dumping side of its pivotal support, so that when loaded the extra weight of the load on the dumping side will overcome the extra weight of the body on the opposite side and shift the center of gravity to the dumping side; but when emptied the center of gravity will shift back to the opposite side to cause the car to reset itself. The method I have illustrated for accomplishing this result consistsin providing that side of the car-body opposite the dumping side with an inclined bottom K and arranging the pivotal support of the body on the dumping side of the center of the body, as seen in Figs. 1 and 2. It results from this construction that when the car-body is loaded the center of gravity is on the dumping side of the pivotal support of the body, and that when empty it is 011 the opposite side of said support. As another method of accomplishing the same result and dispensing with the inclined bot-tom, the pivotal support of the body might be moved to that side of the center opposite the dumping side and that side he made heavier than the dumping side by means of weights or otherwise, which weights, when the body was loaded,would be overcome by the extra weight of the greater part of the load on the dumping side of the piv otal support; or, instead of making the side opposite the (lumping side heavier, the car might be provided with springs which would hold the body in a horizontal position when empty, but whose pressure when the body was loaded would be overcome by the greater weight of the load 011 the dumping side of the body. I prefer the construction employing the inclined bottom, however, for the latter facilitates the dumping of the'load when the car-body is tilted.

The operation of the car illustrated in Figs. 1 and 2 is as follows: Supposing the body to be loaded and locked in a horizontal position with its end-gate closed and latched, the car is moved by any suitable means to the point where it is desired to dump its load, and the latchGis disengaged from the catch 1), either by hand or automatically, by the shoulder e striking the stationary trip It and raising the tripping-arm c. The car-body, being thus released, at once begins to tilt toward the dumping side, owing to the greater weight being on that side of its pivotal support, and the arm j of the latch I, coming in contact with the cross-timber J,disengages the latch I from the gate-catch it, thus unlocking the gate H and permitting it to swing open as the body tilts to the position shown in Fig. 2 to dump its load. As soon as the load is discharged, that side of the body having the inclined bottom being 'now become the heavier, the body tilts back and resets itself to a horizontal position, the end-gate swinging in and becoming relocked and the catch 1) engaging with the latch G, as will be readily understood.

It is of course obvious that the car-body may be hung so as to dump sidewise instead of endwise, in which event the gate would gedupon the side instead of the end of the \Vhile I have shown and described my im proved dumping-car as entirely automatic in the operation of all its parts, and while for some purposes such construction is highly advantageous, yet it is not an essential feature of my invention that all of the parts of the car should operate automatically. Thus in many cases there will be no necessity for automatically releasing the latch G, and in some instances this latch need not be arranged to automatically lock the body when the latter is reset to its horizontal position. Again, many features of the invention may be advantageously used in a dumping-car which is not arranged to automatically reset itself after dumping its load, as where the pivotal support is arranged on that side of the center of the body opposite the dumping side, so that when released the loaded body will tilt to dump its load, but will remain in tilted position until reset by hand. In such cases, especially, can the automatic locking feature of the latch Gr be dispensed with without seloaded, run out to the dumping-point without any attendant going with it, the body be automatically released by the stationary trip, tilted and its load dumped, and be pulled back to the loading-point in its tilted position and be there reset to and locked in a horizontal position by the attendants who load it.

In some instances the car-body may be of such construction that it need have no endgate, and where an end-gate is employed the latch I, arranged to automatically unlock it .when the body is tilted, may be employed with advantage, whether the operation of the other parts of the car are automatic or not.

Having thus fully described my invention, I claim- 1. In a dumping-car, the car-body pivoted between its ends, and having its side opposite the dumping side made heavier than the dumping side, and having the larger part of its carrying-space on the dumping side of its pivotal support, whereby when the car is loaded its center of gravity will be on the dumping side of said support, and when empty it will be on the opposite side of said support, substantially as and for the purpose described.
