DUMPING CAR OR BUGGY.

SPECIFICATION forming part of Letters Patent No. 557,985, dated April 7, 1896. Application filed November 13, 1895. Serial No. 568,786. (No model.)

To 00% whom it may concern:

Be it known that I, J OI-INJ Foss, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga,-andState of Ohio, have invented certain new and useful Improvements in Dumping Cars or Buggies, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a side view of my improved dumping car or buggy; Fig. II, a longitudinal section of the same; Fig. III, an end view, and Fig. IV a transverse section on the line IV IV in Fig. I.

The principal use for which my invention is intended is as applied to buggies such as used in rolling-mills and other places where heavy loads of wire-rod bundles, wire bundles, or other more or less manufactured iron or steel articles are conveyed from one place to another; but it isevident that a dumping device such as herein disclosed may be used for cars of other character and for other purposes by a simple change of the body of the car.

The car-platform A in the present instance is slightly curved transversely, so as to readily shed the bundles of rods when tilted. The

platform has two bracket-frames A near its ends, which frames are formed with bearings a, pivoted upon trunnions b, projecting from the ends of a truck-frame B. Said frame is provided with axle-bearings I), located in a plane above the plane of the trunnions, and the axles O of the truck-wheels O are journaled in said bearings. The wheels are illustrated as flanged, so as to travel on rails D, but may be plain. The bracket-frames are preferably so shaped that their diverging side braces a will not strike the rails when the platform is tilted, but theedge of the platform will strike the ties or ground, as illustrated by dotted lines in Fig. III. The truckframe has at its middle a transverse-arched guide B, concentric with the end trunnions,

cal boxes 6 and e in a cross-frame formed at the middle of the platform by two crosspieces E E,and said bolts slide by their gravity to engage the shoulders of the ribs, so as to thus hold the platform in its horizontal position. A roller e is journaled between the cross-pieces to travel upon the arched surface of the guide, and thus reduce the frictional resistance to the turning of the platform. bracket-bearings upon the trunnions. Two bolts F and F slide in vertical guide boxes F and F extending downward from the center of the arched guide, and said bolts normally register with the gravitating bolts of the tilting platform. Each of the lower bolts has a lug f, which projects laterally through avertical slot f in the guide-box, so that the bolts may be raised by applying force to their lugs. The bolts drop back into their normal lowered positions by their own gravity. I V I I11 practice the platform may be tilted by applying a crowbar or any similar lever to the lug upon the lower push-bolt, which is accessible from the side where the operator stands and the crowbar is applied. The push-bolt may thus be raised and will raise the upper catch-bolt out of engagement with its shoulder, so that the platform may be tilted and will drop to the side away from the operator. As the car or buggy is principally intended for use in rolling-mills and similar places for the transportation of heavy loads of metal, which is very frequently at a red heat, it is of great advantage to have the dumping mechanism so constructed that the platform can only tilt to the side opposite the one on which the person actuating the mechanism stands. All chance of accident from theplatform and load tilting over upon the operator instead of away from him is thus avoided. The bolts return to their normal positions by gravity, so that they may be made very plain and strong and there will be no springs or other parts to break or get out of order, and thereby prevent the locking mechanism from operating properly. As soon as the platform is returned to its horizontal position the catch-bolt, which has been raised and has been bearing against the segmental rib, drops down over the shoulder by gravity, and thus acts as a catch to hold the platform in its normal position.

By having the pivotal points for the platform in a plane below the plane of the truckwheel axles the car may be made sufficiently low to be conveniently loaded, and at the same time the equilibrium of the platform will be sufficiently unstable to admit of its being easily tilted when released, notwithstanding its heavy load. The long radius attained by this arrangement for the are which the platform describes when tilted admits of this desirable unstable equilibrium and also admits of the platform assuming a nearly-vertical position when tilted, thereby insuring perfect discharge of the load without undue height of the car.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Changes may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth respectively in the following claims are employed.

1 therefore particularly point out and distinctly claim as my invention-- 1. In a dumping-car, the combination of a wheeled truck-frame, a platform supported upon said frame to tilt to two opposite sides, two shoulders upon the truck-frame facing to opposite sides, and two catches upon the platform, each of which engages one of said shoulders to admit of the platform being tilted when one catch is withdrawn, to that side away from which the shoulder faces, substan tially as set forth.

2. In a dumping-car, the combination of a wheeled truck-frame, a platform pivotally supported upon said frame to tilt to two opposite sides, an arched guide upon the truckframe having raised segmental portions extending to opposite sides from near the middle of the guide and formed with shoulders at the inner ends of said raised portions facing to opposite sides, and two catches upon the platform each of which engages one shoulder and rides upon one raised portion of the guide when the platform is tilted, substantially as set forth.

3. In a dumping-car, the combination of a wheeled truck-frame, a platform supported upon said frame to tilt to two opposite sides, two shoulders upon the truck-frame facing to opposite sides, two catches upon the platform respectively engaging the shoulders, and two push-bolts arranged in the truck-frame at the bottom of the shoulders to bear against the catches and push them up above the shoulders when raised, substantially as set forth.

4. In a dumping-car, the combination of a Wheeled truck, a platform supported to tilt to opposite sides, an arched guide upon the truck-frame formed with raised segmental portions extending from near the middle of the guide to opposite sides and formed with shoulders at the inner ends of said raised portions, two catch-bolts sliding in vertical boxes upon the platform and respectively engaging the shoulders and sliding upon the raised portion, two vertical boxes upon the guides each of which boxes has its upper end opening at the bottom of a shoulder and a vertical slot in the side facing in the same direction as such shoulder, and push-bolts sliding in said boxes and provided with lugs which project through the slots in the same, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 11th day of November, A. D. 1895.
