Specification of Letters Patent.

Patented July 30, 1907.

Application filed May 19,1906. erial N 317.833-

To all whom all. may concern:

ie it known that I, Enema \Vsns'rnu SUMMERS, of \\*'ilkinsburg, in the county of Allegheny and State of Pennsylvania, have. invented a certain new and useful improvement in tars, of which improvement the following is a specification, reference being had to the ac.- companyingd rawings, forming partol' this Specification, in which; i

Fig. l is a vertical cross section taken in line l1. in Figure 2.

FigfZ is a partial longitudinal section taken in a vertical plane near the center line of the car, as in li ne' 2-2 in Fig. 1.

Fig. 3 is a vertical cross section taken in the same plane as Fig. l, but with the doors shown opened to the center.

Fig. 4 is a sectional plan view taken in line 44 in Fig. 1.

Fig. 5 is a plan view ol' the chain guide and hinge cen tering device for the outside door supporting chains.

Fig. (3 is a side elevation of hinge centering device, showing a portion of the door and taken in line (56 in Fig. 5.

My invention relates to the class of cars having drop bottoms for discharging the load and is designed to provide a simple and ellicient means of discharging the load all in the center between tracks or all outside of rail on either side and to spread the load when discharged between the rails or to push it outward when discharged outside of the rails and thereby prevent the material from falling on the track and obstructing the pathway ol' the wheels,

The arrangement of the car and of the doors and door mechanism designed along lines brought out in my Patent No. 778,384, Dec., 27th. 1904. Some of the improvements in this present application being, lst., the hinge centering device for the outer edge of the doors. 2nd, the lender plates at the ends of the doors for the prevention of an overflow of material at the ends when the doors are lowered and for distributing and spreading the material alter its discharge. 3rd, the throttling beams for checking the liow and controlling the amount of low when discharging material in the center, between rails.

In the drawing, show the doors 1, the outer support-chains 2, the inner supporting chains 3, the outer hinge lug t, the chain guide and hinge centering device 5, the fender plate 6, with its sloping end portion 7, the throttling beams 8.

The door chains 2, at the outer edge of the door pass through the hinge centering device 5, and drawing the door-hinge-lug 4 with its convex surface 9 in contact with the concave surface 10 of the centering device 5, permits the inner edges of the doors to be lowered as shown in Figure 3. This construction serves to retain the outer edges of the doors in their hinge centered position, and also to permit the outer edge of a door to be lowered as shown in Figure l, and to be returned to its closed position, by any means whereby the chains 2 are drawn in and let out. A means is thus provided for centering the hinge at the outer edge 01' the door while the inner edge is being opened, and for releasing the hinge at the outer edge and opening that portion while the inner support is acting as a hinge.

The hinge centering device 5 is preferably made of cast metal, but may be made of any material.

The lender plate (5 is arranged transversely of the car, with it major portion extending in a vertical plane and at right angles with the hinge axes of the doors, and with its end portions 7 extending at an angle with its major portion, and preferably in a vertical plane, the angular direction being away from the door and the door opening for the purpose of pushing or plowing a mass of discharged material outward from the car track by the car moving along the track while the load is being discharged. I

The throttling beams 8 shown in section in Fig. 3 and in partial longitudinal elevation in Fig. 2 are purposely omitted in Figs. 1 and 4, and extend from fender plate o near one end of the car to a corresponding fender plate near the other end of the car, the car being by preference symmetrical in this respect about its transverse center line. The throttling beams 8 are located at such a height above the track and have such distance between the beams taken transversely of the track that materials discharged from the car by opening the doors 1 in the center to any position 11 as shown by dotted lines in Fig. 3 will cause the materials to lodge in some position 12 as shown by irregular lines 13 in Fig. 3, leaving the track railsiree of obstruction by the discharged materials. The said throttle beams 8 have also a position which leaves an open space between the lower edge of door 1 and the top edge of beam 8 which will permit the insertion of a bar to dislodge any material that may bridge the opening and check the ilow.

For the sake of clearness the doors 1 are shown in Fig. 1 with one of them in its closed position and the other one in its open position for outside dumping, but either door may be lowered or raised at its outer edge independent of the other or both doors may be lowered or raisedat their inner edge simultaneously.

Many changes may be made in the form, arrangement and number of doors, position and shape of the hinge centering device, location or shape of the throttling beams, position, extent or angular location of fender plate without departing from my invention.

I claimz- 1. In a car, a hinge member on a door which isrelensnble from its hinging position, and a hinge centering member fixed on the car, one of such members having a convex surface and the other of such members having a eoiiperating concave surface.

2. In a car, a hinge on a door which is releasable from its hinging position, and an open sided pocket fixed on the car for centering the door hinge lug,

In a car, a door having a movable support for its hinge, a hinge centering device fixed on the car, the said hinge centering device having an open sided pocket which is concentrically arranged around the hinge center, to permit of the removal of the hinge from the pocket.

4. In a car, a tender extending transversely of the car forits middle portion. its end portions extending at an angle between the transverse and longitudinal direction of the car, and a door opening positioned for discharging materials to the side of the car and adjacent the end portion of the fender, which materials ma be moved outward from the car by the action of the inclined fender when the car is moved along its line of travel.

6. In a car. a pair of throttling beams having a location under and longitudinally of the car, and a door opening for discharging material between thethroitling beams, the throttling beams being located in position to eontrol the Ilow of the material.

7. In a car, a pair of beams located longitudinally of the car and near the-ear track surface, the beams being separated to permit of a discharge of material between the beams, a door opening above the beams. and a space be tween the door and beams Avhen the door is open, for the purpose set forth.

8. In a center dumping cal ya pair of doors hinged on longitudinal axes, the doors opening at the center line of the car. a pair of beams arranged under the door opening.

with an open space between the beams, the lower edges of the beams being at such a height above the car track as to check the lateral flow of discharged granular materials and heap it away from the rails.

S1. The combination with a dump ear adapted to discharge at the side and at the center. of a tender comprising a central portion extending across the car at sub stantially a right angle to the axis of the ear and an obliquely extending end portion.

10. The combination with a dump car provided at its lower portion with a door adapted to s\vi g laterally to permit oi a discharge to-the side of the ear. of a fender extending across the car adjacent the end of the door at substantialhr a right angle to the a is oi the car and provided with an obliquely extending end portion.

In testimony whereof, I have hereunto set my hand.
