RAILWAY-DUMP.

Specification of Letters Patent. Patented Decllfi, 1919.

Application filed- April 7, 1917. Serial No. 160,427.

To all whom it may concern:

Be it known that I, ALEXANDER I-I. Wool), a citizen of the United States, residing at Kildav, in the county of Harlan and State of Kentucky, have invented a new and useful Improvement in Railway-Dumps, of which the following is a specification, reference being had to the accompanying draw- Ii Iy improvement relates particularly to railway dumps which receive loaded cars upon one track and discharge said cars, when empty, from the same end of the dump and upon another track, the movement of the cars toward and from the dump being usually by gravity.

The object of the invention is to provide an adjacent dumping structure by means of which loaded cars may quickly en ter the dump, discharge their loads, and move out upon the discharge or return track.

In the accompanying drawings,

Figure l is a plan of a structure embodying my improvement, portions being omitted;

Fig. 2 is a side elevation of the same structure, portions being broken away;

Fig. 3 is a section on the line, 3-3, of Fig. 1, looking toward the left;

Fig. 4. is a section on the line, 3-3, of Fig. 1, looking toward the right;

Fig. 5 is a detail elevation;

Fig. 6 is a view similar to Fig. 3, showing mechanism for shifting the platform;

Fig. 7 is a detail upright section.

Referring to said drawings, A is an understructure such as is ordinarily used for supporting car dumping mechanism, excepting that in the present case this understructure is modified to meet specific requirements. On the understructure, A, is a shiftable platform, B. At one end (the left hand end in the drawing), said platform is supported by a swivel structure having an upright axis B and resting on the understucture, A.

At its free end (the right hand end in the drawing), said platform is supported by wheels, B which have axes, parallel to the length of said platform and which wheels rest on a track rail, A on the understructure, A, said rail being curved with the pivot, B for a center. Intermediate its ends, said platform is provided with another pair of wheels, B resting on a rail, A which is parallel to the rail, A and also supported by the structure, A. The platform may be turned on its pivot, the

free end of the platform traversing the length of the rail, A

A car track, '0, leads from the right to he free or right hand end of the platform, the latter being in the position shown in Fig. 1, the position in which loaded cars are to be received from the track for dumping- For convenience in description this position will be called the receiving position, while the position on the other end of the rail, A is called the discharge position.

A car track, D, leads from the structure, A, beside the track, C, and in .position'to register with the platform, B, when the latter has been turned into the discharge position.

The tracks, C and D, are placed at proper elevations to register with the track inthe rotary tubular frame supported on the platform, B, as hereinafter described.

The rails, A and A are inclined, the lower position being adjacent the track, D, in order that the free end of the platform may be lower when it is opposite the track, D, than when it is opposite the track, C. This brings the two ends of the platform to the same level when the platform is alined with the track, C, and brings the ,free end of the platform lower when the platform is alined with the track, D. The purpose of this latter feature is to facilitate discharge of empty cars from the dump outward upon the track, D. A stop post, E, limits the movement of the platform away from the track, D; and a similar stop post, E limits the movement of the platform in the opposite direction. A cable or chain, E is attached to the platform adjacent the post, E, and leads horizontally and at right angles from the platform over a sheave, E downward to a counterweight, E The counterweight thus suspended is to be made suffi cient to draw the platform, when the latter supports no cars, toward the sheave, E, until the platform meets the stop, E. But while said counterweight is to be heavy enough to perform the function just described, it is to be light enough to permit easy movement of the platform away from the post, E, when the platform supports a trip of cars. These several parts are prefera'bly so proportioned as to permit the platform, when loaded with a trip of cars to overcome the counterweight and move over the inclined rails, A and A until the platform meets the stop post, E The movement of the platform away from the post, E, may be facilitated by applying power to the wheel, E on the shaft, E of the sheave, E to turn the latter so as to lift the counterweight.

In Fig. 6 the cable, E and the counterweight, E*, are omitted, and a cable, E, is attached to the adjacent portion of the platform, B, and then around the sheave, E and thence beneath the platform and beneath a sheave, E adjacent the stop post, E and thence over said sheave into engagement with the adjacent edge of the platform. By turning the wheel, E, in the appropriate direction, the platform is drawn away from the post, E, and to the post, E and by rotating said wheel in the opposite direction, the platfo in is returned to its position against the post, E.

For holding the platform in the receiving position, a hook, E is hinged to the edge of the body, 13, at E in position to extend over a horizontal stud, E, on the right hand side of the post, E, said hook having at its outer end an oblique face, E adapted to slide over the stud, B, when the platform, B, moves against the post, E, whereby the engagement of said hook is made automatic. For holding the platform in the discharge position, against the action of the counterweight, a hook, E is placed at the opposite side of the platform to engage a stud, E, on the post, E

On the platform, B, are wheels, F, arranged with their aXes on two lines which are parallel to each other and to the length of the platform, and said wheels are sup ported upon bearings, F Said wheels make supports for a tubular cylindrical frame, G, formed of longitudinal bars, G and trans verse rings, 6*, the latter resting on the wheels, F. W'ithin said tubular frame are longitudinal track rails, G which are adapted to register with the rails of the track, C, when the platform, B, is in alinement with that track and to register with the rails of the track, D, when the platform is in alinement with that track. Above the rails, G are upper rails, G, which are above the path of the wheels, H of the car, I-I. Said four rails are adapted to hold the car during the rotation of the tubular frame, G, for inverting the car to discharge its contents by gravity. For further details concerning such a rotary tubular dumping frame, reference is made to Letters Patent of the United States, No. 1,204,527, granted to me November f, 1916. The mechanism for rotating said tubular frame may be of any suitable form. For this purpose, the drawings show the wheels, F, at one side of said tubular frame mounted on a continuous shaft, F and an electric motor, I, mounted upon the platform, B, and connected with said shaft by gears, P, I I and I (Fig. 7);

Oaths structure, A, atthe pivot end of the platform is a buffer, J, of any suitable form and standing high enough to be engaged by cars which tend to move through the tubular frame, G.

In operation, the platform, B, is put into the receiving position, in alinement with the track, G. Any number of loaded cars suited frame for the discharging of the loads from I the cars. Or the rotation of the tube may be deferred .until the platform has been moved to the discharge position. In some situations, this may be desirable because then the weight of the loads in the cars will help to move the platform from the receiving position over the inclined rails, A and A into the discharge position, the counterweight, E having opposed to it the weight of the trip of cars plus the weight of the loads in said cars.

Before the platform is shifted out of the receiving position, the cars should be secured against movement toward the discharge end of the tube. This can be done by means of suitable blocks or similar devices placed in front of a portion of the car wheels. When the platform stands in the discharge position and the cars are empty and the tubular frame has been righted so that the rails, G of the tubular frame, G, register with the rails of the track, D, said blocking is removed to allow said cars to run by gravity out of the tubular frame and over the track, D.

The hook, E, (if it is used) is now re leased to allow the counterweight to draw the platform back into the receiving position to receive another trip of cars.

I claim as my invention,

In an apparatus of the nature described, two car tracks located and terminating sidebyside, at different elevations, an understructure located adjacent the ends of said tracks and having an inclined track trans verse to said two tracks, a platform supported upon said understructure track and swiveled at one end and turnable on said swivel to brin the free end of said platform alternately opposite said car tracks, and means on said platform for receiving a car from one of said tracks and supporting said car.

while its load is being discharged substantially as described.

In testimony whereof I have signed my name this tenth day of March, in the year one thousand nine hundred and seventeen.
