UNLOADING APPARATUS.

SPECIFICATION forming partof Letters' Paten'tNo. 373,222, dated November 15, 1887.

Application filed August 6, 1887.

.To @ZZ whom Vit may concern:

Be it known that I, BAYARD GHALEANT, a citizen of the United States, residingat Kinmundy, in the county of Marion and State of Illinois, have invented a new and useful Improvement in YUnloading Apparatuses, of which the following is a specication.

My invention relates to improvements in machines for unloading; and it consists in a certain novel construction and arrangement of parts, fully set forth hereinafter, and specifically pointed out in the claims.

In the drawings, Figure 1 is aside view of the device. Fig. 2 is a longitudinal section thereof. Fig. 3 is a central transverse section.

Referring by letter to the drawings, Av designates the framework, which is built over the pit into which the coal or grain is to be deposited,and in suitable bearings in the said framework on the level of the track along which the cars to be unloaded are moved is mounted the shaft B, carrying the tilting frame or track C. The said tilting frame is provided on the upper side with rails on which to run' the car, and the under portion is strongly trussed to enable it to bear a great weight.

D D arey rods or bars passed through or firmly secured to the tilting frame at each end, and projecting beyond the sides thereof, and to the ends'of the said rods are secured the ends of the wire ropes or cables E,which pass from thence up and over the sheaves F F at the top o'f the frame and near the ends and areattached at the centers to the drums G, which are arranged at the center of the frame. The sheaves FF at each end ofthe frame are secured to transverse rods f f, and thus they will turn simultaneously, and the drums G G are also secured on a transverse rod, g, which is extended outwardly on one side of the frame and provided on the end with thegear-wheel H.- It will be readily seen that as the wire rope is secured rigidly at the center to the drum, as the latter is rotated the rope on one side thereof will be Wound thereon and the rope on the other side will be unwound,and consequently the tilting track will be inclined, as shown in dotted lines in the drawings.

I Iindicatev sheaves secured to the inner sides of the frame about on the level of the ground, on which the cables bear when the Serial No. 246,306. (No model.)

be attached to the link of the car which is on the track, While to the lower end is attached a rope, chain, or cable, k, which is'fastened at the other end to a convenient beam under the track. The object of this device is obvious. When the car is run on the track, the holdback is swung down into the position shown in dotted lines to allow the car to pass over, after which it is raised and the upper end thereof engaged with the link on the end of the car. `The chain attached to the lower end of the lever is now drawn tight and secured, thus preventing the car from running off the track when it is tilted in the opposite direction.

L designates a chute which is secured to the tilting track after the car is secured in place thereon, and the said chuteis arranged at the end of the car close under the opening Mtherei'n. rlhe said opening in the end of the car is provided on the outside with a swinging door, M', hinged at the upper edge and adapted to swing out as the car is tilted, and it may be secured in any preferred manner at the lower edge.

.N designates-a vertically-sliding door ar-V ranged on the inside of the opening M and sliding in ways n n, provided therefor at the sides of the opening. To the upper edge of the said door at each end is attached a short chain, O, which passes up over a transverse bar, l?, arranged tran'sversely across the end of the car above the opening M and mounted in suitable bearings. The said bar P is provided at the center with a block, P', provided with aseries of peripheral sockets, in which the end of the lever-bar R isv adapted to be inserted to turn the block, and consequently the bar is secured thereto. In this way the chains are wound on the ends of the rod and the door N is raised to allow the passage of the grain or coal.

S designates a small platform arranged on the side of the frame A near the top thereof, and in suitable brackets or standards on the said platform i s mounted the horizontal shaft IOO T, comprising the driving-shaft ofthe engine, which is supported on the platform, but not shown in the drawings. The inner end of the horizontal shaft is provided with a gear-wheel, t, to mesh with the wheel H.

U designates a brake-wheel, also secured to the said shaft and adapted to be operated upon bya brake to regulate the motion of the shaft, and consequently of the tilting frame, when the car is being emptied. The said wheel also serves as a balance-wheel to render the motion of the engine steady and pass over centers.

The operation of the invention will be obvious from the above. The carto be unloaded is run on the tilting track, the holdback or locking-bar K is attached to the link in the end of the car to prevent the latter from sliding oft' the track when tilted, and the chute is adjusted and secured in any preferred manner at the end of the car which is designed t-o be lowered. The sliding door in the end of the car is now raised and everything is in readiness to unload. The shaft Tis now rotated by the power, thus turning the gear-wheel H, and .consequently the drums which are attached to the same shaft as the gear-wheel, and the track is tilted and the contents of the car pass through the opening M. When the car is empty, the engine or power is reversed and the track returned to its horizontal position, when the car is run off, and the device is ready to receive another full car.

The device is very simple and easily managed, and if when the car is run on the track it is arranged so as to be balanced it will be seen that very little power is necessary to tilt the track.

The operation of the invention being simple and direct, a car may be emptied in a very short time.

rIhe drawings show the device adapted to empty the ear at either end-that is, to tilt in either direction; but it will be seen that this may be alt-ered at will, as there are few cases in which it is of advantage to tilt in both directions.

Having thus described my invention, I claim- 1. The combination of the supporting-frame A, the drum or windlass G in the upper central portion thereof, provided with suitable operating mechanism, the sheaves F near the outer ends of said frame, the tilting track supported in said frame and mounted on a pivotal rod, the cable E, connected to the supporting-frame of the tilting track and, passing over the sheaves F, engaging with the drum G, the anti-frictional sheaves or pulleys I at the lower outer ends of the track frame, adapted to engage the cable E, the lever-arm K, pivotally mounted at one end of the frame A and adapted to be secured at its upper end to the coupling link or chain on the end of the car, and the cable 7c, attached to the lower end of said lever to hold it in a vertical position against the action of the coupling link or chain, substantially as described.

2. In combination with the frame A, having the drum or windlass G, and the sheaves or pulleys F, arranged in the Lipper portion thereof, as shown and described, the tilting track mounted in said frame A, as set forth, the anti-frictional sheaves or pulleys I at the lower ends of said tilting track, and the cable E, secured to the tilting track and passing over the pulleys or sheaves I [and F and engaged and operated by the Windlass or drum G, as set forth, substantially as described.

3. rIhe combination, with the frame A and the tilting track pivoted therein and adapted to be inclined longitudinally, of the car having the openings M in the ends, the pivoted outer doors, M', to close the said openings, and the sliding inner doors, N, operating in vertical ways, the transverse bars l? above the doors, chains connected to the doors and adapted to be wound on the said bars, block P on the centers of the bars, provided with peripheral sockets, and the lever R, to insert in one of the sockets to turn the block, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

BAYARD CHALFANT.
