RAILWAY CAR WALL Filed June 8,. 1935 Patented Aug. 11, 1936 UNITED STATES RAILWAY CAR WALL Garth G. Gilpin, Riverside, Ill., assignor to Union Metal Products Company, Chicago, 111., a corporation of Delaware Application June 8, 1935, Serial No. 25,631

3 Claims.

The invention relates to railway freight cars and more particularly to side and end walls for open top railway cars, such as hopper and gondola cars, though the construction is adaptable for walls of house cars, such as box, automobile and refrigerator cars. The construction is also adaptable for use as roofs, floors, hopper doors and side doors for railway cars. A roof or a floor comes within the meaning of the term wall as used in the specification.

Railway freight cars are generally designed so that the side walls are girders or trusses to carry part of the weight of the lading and the car itself to the body bolsters which transmit such load to the trucks. Such side walls also retain the load in the car. It is desirable to make the inside horizontal width of the car as wide as possible to increase the cubical capacity of the car but the outside width of the car is limited by tunnels and projections adjacent the track so it becomes imperative to make the side wall as thin horizontally as possible consistent with strength requirements.

Open top railway cars are frequently built with the vertical walls comprising spaced apart upper and lower frame members connected at spaced intervals by vertical posts with panels filling the spaces between the posts and frame members, which construction forms a girder and retaining wall. It has been proposed to bulge the central parts of these panels outwardly to increase the cubical capacity of the car, such as shown in the I-Iart Patent No. 1,623,591 of April 5, 1927.

An object of the invention is to provide a wall for a railway car comprising a continuous lower chord and a plurality of wall sections secured to the lower chord having their vertical margins meeting and secured together to form a continuous wall and to provide each of such sections with a member adjacent its upper margin and to secure members of the several sections together so as to provide a substantially continuous upper chord. The lower chord of a railway car wall is secured to the bolster, end sill and other cross bearers of the underframe and, therefore, is difficult and expensive to remove from the car. The several sections of my construction, that is, one or more of them, can be easily removed and replaced for repairs and sections may be made and stocked in anticipation of repairs, and furthermore when making new cars such sections may be made in quantities and shipped to place of assemblage as required.

Another object is to provide an upper chord for a car wall having a substantially horizontal part and a downwardly and outwardly inclined part extending from the inner margin of said horizontal part. The horizontal part provides strength in a horizontal direction and the di- 5 agonally inclined part not only provides strength in a vertical direction but also sheds the load when JG car is in an unloading machine.

Another object is 'to provide a wall composed largely of flat plates or sheets which are not 10 flanged or deformed but merely have their edges welded or otherwise secured to the chords and posts of the side wall.

In the drawing:

Fig. 1 shows part of a railway car incorporat- ]5 ing my invention wherein the component parts are secured together by welding.

Fig. 2 shows a construction similar to Fig. 1 wherein the component parts are secured together by riveting. 20

In the drawing the lower side chord 2 extends continuously through the width of several sections and preferably between the bolsters of the car.

Spaced apart posts 6-8, the upper members liii 2, and the wall sheets I4-l 6 are secured together to form a unit or section. A plurality of such sections are secured to the lower chord 2, by welding, as shown in Fig. 1, or by riveting, as shown in Fig. 2, and also the posts of adjacent sections are secured together to form a continuous wall. The upper members l0l2 are rigidly secured together at their meeting margins to form a continuous upper chord. These members l6i2 are preferably welded together.

The upper chord comprises a substantially horizontal part 23, an outer depending flange 2i and a downwardly and outwardly inclined part 22 extending from the inner margin of the horizontal part and preferably also a depending flange 23 extending from the lower part of the diagonal part. Each post or stake 6 comprises a part 26 extending laterally of the car and a flange 21 extending longitudinally of the car. The post extends upwardly and is secured to the horizontal 45 portion If of the upper chord (28). The diagonal portion 22 of the upper chord extends and is secured to the part 26 of the post (29) The accompanying drawing illustrates the preferred form of the invention, though it is to be 50 understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.

I claim:

1. A wall for a railway car comprising a continuous lower chord, a plurality of wall sections secured to said lower chord with their vertical margins abutting and secured together to form a continuous wall, each of said sections having a member adjacent its upper margin, and means to secure said members together to form a continuous upper chord.

2. A wall for a railway car comprising a continuous lower chord, a plurality of wall sections secured to said lower chord, each of said sections comprising spaced apart vertical posts, a member adjacent the upper margin of the section having a horizontal part and a downwardly and outwardly inclined portion extending from the inner margin of the horizontal part, and a wall sheet secured to the posts and the member, means to secure the posts of adjacent sections together, and means to secure the members of adjacent sections together to form a continuous upper chord.

3. A wall for a railway car comprising a continuous lower chord, a plurality of wall sections secured to said lower chord, each of said sections comprising spaced apart vertical posts, a member adjacent the upper margin of the section having a horizontal part and a downwardly and outwardly inclined portion extending from the inner margin of the horizontal part, and a fiat wall sheet secured to the posts and the member, means to secure the posts of adjacent sections together, and means to secure the members of adjacent sections together to form a continuous upper chord.
