PATENT GFFICE RAILWAY CAR CONSTRUCTION Garth G. Gilpin, Riverside, Ill., assignor to Union Metal Products Company, Chicago, Ill., a cor- The construction relates to railway cars, particularly the open topl car, that is, hopper or gondola cars wherein the side walls form trusses or girders to carry a part of the load to the body bolsters.

The object of the invention is to provide a side wall which not only performs the function of a girder, but is so arranged to obtain approximately the maximum cubical capacity of the car within a given width and height thereof, and a further object is to provide a post or strut between the top and bottom chords of the girder, which strut is provided by a new and novel arrangement and formation of the side wall sheets or web members of the girder in combination with a cover plate, which construction is hereinafter described. The major part of the central portion of each wall sheet is bulged outwardly to increase the cubical capacity of the car and the bulged portions of adjacent sheets are secured together (preferably by a cover plate or stripl of metal) to form a vertical beam between the chords. Such cover plates are preferably formed to provide stiffeners between the adjacent chord and the bulged central portion and to provide a strut between the upper and lower chords.

A further object of the invention is to provide a stiffening means between the struts and the adjacent chord of the girder.

Another object of the invention is to provide such a wall for a railway car which can be made of flat metallic sheets and wherein the wall sheets and cover plates are so shaped that they can be formed between reciprocating dies in a press.

The side wall or girder of the railway car shown in Fig. l comprises an upper chord 2 and lower chord 3, and wall sheets 4 forming the web of the girder. The girder extends between the bolsters 5, which bolsters transmit the load to the 55' trucks.

1932, Serial No. 600,209

(Cl. 10S- 249) The top chord 2 is preferably a rolled beam of angular section having a horizontal portion 8 and a vertical portion 9. The lower chord 3 is also preferably a rolled beam of angular section having a horizontal portion l l and a vertical portion l2. The wall sheets l are secured to the vertical portions (ll-l2) of the upper chord and lower chord, respectively, through their end marginal portions I5 l5. The central or main portion I8 of each wall sheet is positioned in a spaced apart plane from the end marginal portions l5 l6 and connected thereto by an upper sloping web portion 20 and a lower sloping web portion 22, thus the cubical capacity of the car is increased.

The vertical web portions 24 of the wall sheets merge into the vertical or side marginal portions l25 and such vertical side marginal portions 25 of adjacent sheets are secured together, as shown in Fig. 6. A cover plate 36 spans the difference between the adjacent webs 24 and overlaps and is secured to the central portions i8 of adjacent wall sheets to form a box girder construction, as shown in Fig. 6. The cover plate is preferably extended and secured to the upper (2) and lower (3) chords, respectively. This arrangement forms a very strong strut between the upper and lower chords and also forms a very strong vertical beam against the tendency of the lading to bulge the side walls and also makes a very light and inexpensive structure.

One end of the cover plate (or preferably both ends thereof) is folded to form a corrugation 32 with outwardly extending flanges 33, which flanges are preferably secured to the adjacent chord and also preferably secured to the upper web portions 20 of the wall sheets, as shown at 34 in Figs. 2 and '7. This corrugation 32 makes a very strong structure between the upper inclined web 20 of the wall sheet and the topi chord 2, as shown in Figs. 2 and 3, and also between the lower inclined web 22 of the wall kplate and the bottom chord. 3, as shown in Figs. 4 and 5. The upper corrugation, the lower corrugations and the vertical webs 24 of the wall sheet all combine tomake a very strongstrut and/or beam between the top and the upper and lower chords of the girder.

In hopper cars, such as shown in the drawings,

the body bolster 5 extends vertically from the bottom of the sloping floor 40 to the bottom of the side girder (4l) and the lower sloping web- 42 of the wall sheets adjacent the sloping floor, are formed substantially parallel to the sloping floor. The cover plate 44 is secured to the sloping web 42 by the rivet 45 and the corrugation 46 extends from the sloping web to the lower chord 3.

The end side sheet 50 is provided with an end portion 5I between the end wall 52 of the car and the vertical web 53 to accomodate the ladder rungs 54.

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modications thereof, within the scope of the claims, will occur to persons skilled in the art.
