To all whom it may concern.-

Be it known that I, ARTHUR B. BELLOWS, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Railway- Car, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 shows in side elevation, partly in longitudinal section, a car constructed in accordance with my invention. Fig. 2 is aperspective view showing the construction of the margin of the sides and ends of the car. Fig. 3 is a longitudinal section showing the cardoor open, the doors being shown closed in Fig. 1. Fig. i is a vertical cross-section of the car with the doors closed on the line IV IV of Fig. 1. Fig. 5 illustrates a modification of the door mechanism.

In the drawings, 2 2 are the sides and ends of a hopper-car made of plate-girders, and 3 3 are the center sills. The sills are divided at the middle and are intersected by a crossbeam 4, to which they are fixed at their ends, and the ends of the cross-beam are fixed t0 the plate-girder sides, so that the weight at the center is supported by the sides of the car. This affords a good support for the cross-transom 5, to which the hopper-doors are hinged, and thus makes the structure as a whole very strong and substantial.

6 6 are the four hoppers of the car, Whose doors '7 7 open outwardly from the center and are hinged to the transom at 8 on the outer sides of the center sills. I employ novel mechanism for opening and closing these doors. The doors are connected by chains 9 and 10. As shown in Fig. 3, the chain 9 is connected at one end to a cross-beam 11, connecting the two doors at the right, thence passes around a sheave 12, and its other end is connected to a like beam 11, connecting the doors at the left. In like manner the chain 10 is secured at one end to the beam 11, thence passes around a sheave 13, and its other end is connected to the beam 11. One of the sheaves 12 13 is provided with a cross-shaft 14:, which may be turned by awrench orhandle at the side of the car. The strands of the chains are separated laterally by a chafingplate 15, and the sheaves and chains are set in the space between the center sills and are thus protected from injury by the load of the car when it is being discharged. If the doors be closed, as shown in Fig. 1, and itis desired to open them, the operator turns the shaft 14, whereupon the chains are moved in the direction of the arrows in Fig. 1 and the doors are moved oppositely to each other to the open position shown in Fig. 3. The chains being, in effect, one endless chain, this does not tighten or loosen the strands, so that there is no slack to take up. All four doors are opened at one operation by turning the single shaft 14. The sheave 13 may be a mere carrierpulley and need not be provided with ashaft. A reverse motion of the shaft 14 will move the chains in the direction of the arrows in Fig. 3 and will close the doors. The chains may be provided with suitable turnbuckles 16,

enabling them to be adjusted for the purpose of taking up wear. The simplicity of this door mechanism will be appreciated by those skilled in the art. It enables the doors to be opened to a wide extent, and all the doors can be moved by a single operation and with less complicated mechanism than has been known before.

In Fig. 2 I show a construction of the carbody designed to afford strength and stiffness to the sides and ends. The plates of both the sides and ends of the car are strengthened at the margin by two flanged sections 17 18, set on opposite sides of the plates and extending along the full length of the ends and sides, the flange of one being uppermost and the flange of the other being down and both being connected by rivets 19,which pass through the flanged sections and the plate.

In Fig. 5 I show a modification of my invention in which the construction is the same as shown in Fig. 3, except that the upper strand of the chain 10 does not pass to the right-hand door, but is wound upon the shaft 13'. In this case the turning of the shaft 13 will close the doors and the reverse motion of the sheave will permit the doors to open by gravity. The construction shown in Fig. 3 is preferable, however, because it enables the doors to be opened positively to a much larger extent for a free egress of the load.

By the word free in the claims as applied to the angle-flanges I intend to cover flanges which are not riveted or secured together, but are free to spring under the strains imparted thereto by the load.

Within the scope of my invention as defined in the claims the skilled mechanic will be able to modify the construction of the car, since What I claim is 1. A car having doors opening in opposite directions, a chain connected to said doors and arranged to open and close both of them, and a sheave engaging the chain and arranged to pay out one portion of said chain 'as it takes in another portion; substantially as described.

2. A car having doors opening in opposite directions, a chain fastened to said doors at two points in its length and arranged to open and close both of said doors, and sheaves engaging the chain and arranged to pay out one portion thereof as they take in another portion of said chain; substantially as described.

3. A car having transversely -extending doors arranged to move toward each other in opening, each door having a hinge member mounted in fixed bearings, and a chain having connections arranged to positively draw said doors into open position; substantially as described.

4:. A car having oppositely-opening doors, a chain fastened to said doors at two points in its length and extending from the fixed point on one door around a sheave to the other door, the sheaves being located on opposite sides of the middle of the car, and arranged to pay out one portion of the chain as another portion is taken in; substantially as described. 4

5. A car having a plate structure forming at least a part of its side and extending longitudinally from end to end thereof, said structure having at its upper edge two rolled rightangled angles secured to its opposite faces, said angles extending horizontally and parallel throughout their entire lengths, the vertical legs of the angle being parallel with the plate side and their flanges being free and parallel with each other throughout, at least one of said flanges covering the upper edge of the side, the securing-rivets for the angles extending through three thicknesses only of metal; substantially as described.

6. A hopper-car having plate-girder sides, a cross-transom and hoppers whose openings face each other on opposite sides of the center of the car, a divided center sill, and a cross floor-beam fastened between the end portions of the center sill and secured at the ends to the plate-girder sides of the car the divided sections of the center sill being separated longitudinally by the cross-beam; substantially as described.

7 A car having doors, chains connected with the doors and having crossing strands, and a chafing-plate interposed between said strands; substantially as described.

8. A car havinga plate end with two rolled right-angled angles secured thereto by the same rivets extending through their vertical legs and the plate end only, the flanges of the angles being parallel and horizontal throughout their entire lengths, at least one of the angle-flanges covering the upper edge of the plate end; substantially as described.

9. A car having a plate side extending from end to end of the load-inclosing structure, and two rolled right-angled angles secured to the top edge of the plate side by the same rivets extending only through their vertical legs and the plate side, said angles extending horizontally and parallel throughout their entire lengths. with their vertical legs on opposite sides of the plate structure, one of the angle-flanges covering the upper edge of the plate structure; substantially as described.

In testimony whereof I have hereunto set my hand.
