July 4, 1939. I K. EDAHL METALLIC WALL STRUCTURE Filed Oct. 27, 1937 ATTOR N EY Patented July 4, 1939 UNITED STATES PATENT OFFICE METALLIC WALL STRUCTURE 4 Claims.

This invention relates to metallic wall structures adapted particularly for employment in railway freight cars, trucks, containers and the like.

It is an object of this invention to provide metallic wall structures characterized by relatively greater strength and capable of effectively resisting forces from the inside as well as from the outside of the structure in which they may be utilized.

A further object is to provide metallic wall structures for railway cars, trucks, containers and the like constructed to obviate damage to lading in general and to cattle in particular and thus to eliminate damage claims frequently arising through the employment of wooden sheathing.

A further object is to provide metal sheathed stock cars which will be sanitary and inhibit such diseases in cattle as arise from their contact with germ infested wooden sheathed stock cars.

A further object is to provide metallic wall structures for railway cars, trucks, containers and the like embodying metal sheathing presenting rounded corners and thereby preventing damage to commodities and injury to cattle.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawing forming part of the specification:

Figure l is a partial sectional view through a railway freight car wall embodying the invention.

Figure 2 is a horizontal section taken on line 22 of Figure 1.

Figure 3 is a diagrammatic View partly in section looking at the inside of a wall of a freight car.

Figure 4 is a diagrammatic view partly in section of the car as seen in horizontal section.

Figure 5 is a diagrammatic view partly in sec- 40 tion looking at the inside of an end of the car.

Figure 6 is a partial elevation of a modified form of the invention.

Figure 7 is a horizontal section taken on line 'l1 of Figure 6.

Figure 8 is a vertical section taken on line 8-8 of Figure 6.

Referring first to Figures 1 to 5 inclusive of the drawing illustrating an embodiment of the invention, the numeral l0 designates a railway car of 50 the stock car type. This car embodies the customary underframe indicated as a whole by the reference numeral H and side plates l2l2 upon which the car roof I3 is supported. A door opening adapted to be controlled by the usual outside sliding door is indicated at I4 in each of the side Walls I5 of the car. The customary running board I6 is supported upon the roof by means of the brackets ll.

Each of the side walls [5 embodies a plurality of spaced metallic posts 58 preferably Z-shaped in 5 section as shown in Figure 2 of the drawing extending between and secured to a side plate l2 and the underframe II. Fastened preferably to the inside of these posts is a plurality of metallic sheathing sections l9. As clearly appears from Figure 1' of the drawing each of these sections embodies a. plurality of corrugations 20 which are disposed at right angles to the posts [8. To provide for the necessary circulation of air in the car, the sections l9 are spaced vertically as indicated in Figure l of the drawing. It is to be observed that the corners of the corrugations 20 are rounded and the sheathing sections [9 are such that no sharp edges are presented. Damage to lading and injury to cattle is thereby precluded.

It will appear, moreover, that the inherent rigidity of the corrugated sheathing sections presents a very strong wall structure which at the same time is sanitary and prevents the nesting and development of germs and microbes which may prove injurious to cattle.

The instant invention is carried into the end wall 2! as well. This wall comprises end posts 22 preferably of Z section and metallic sheathing sections l9 fastened to the posts as by rivets. As in the side wall construction the sheathing sections it; are arranged so that the corrugations 20 extend at right angles to the posts. A very strong end wall structure is thus provided.

A further embodiment of the invention is illustrated in Figures 7 to 9 inclusive of the draw ing. The sheathing 23 utilized in this embodiment is formed of a substantially flat plate fabricated to provide vertical intermediate members 24 and end members 25 and 26. Extending between the intermediate and end vertical members is a plurality of horizontal members 21 separated by apertures 28. The middle of the metallic sheathing 23 is turned outwardly around the apertures 28 to provide the outwardly extending horizontal and vertical flanges 29 and 39. It will thus be apparent that the metallic sheathing 23 is formed of a plurality of sections each of which 50 embodies in a unitary structure the vertical, intermediate and end members connected together by the horizontal members. Strength and rigidity are secured by means of the outwardly extending flanges 29 and 30 so formed as to provide a smooth interior surface, all corners of which are rounded.

In the securement of the sections of the metallic sheathing to the posts l8 the intermediate vertical member 24 is riveted to a post while the end vertical members of adjacent sheathing sections are overlapped as clearly illustrated in Figure 9 of the drawings. The relationship of the sheathing 23 with the metallic posts 18 is such that the outwardly directed flanges 29 and 30 terminate within the outer plane of the posts.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention, which is to be limited only by the scope or" the claims appended hereto.

I claim:

1. A metallic wall structure for railway cars, trucks, containers and the like, comprising metallic posts, single ply metallic sheathing extending between and secured to said posts, said sheathing having a substantially smooth inner face and embodying vertically arranged alternate solid portions and apertures, said solid portions around said apertures being formed with outwardly extending reinforcing flanges.

2. A metallic wall structure for railway cars, trucks, containers and the like, comprising metallic posts, single ply metallic sheathing extending between and secured to said posts, said sheathing having a substantially smooth inner face and embodying vertically arranged alternate solid portions and apertures, said solid portions around said apertures being formed with outwardly extending reinforcing flanges, said flanges terminating within the outer plane of said posts.

3. A metallic wall structure for railway cars, trucks, containers and the like, comprising metallic posts, single ply metallic sheathing extending between and secured to said posts, said sheathing embodying spaced vertically extending portions, a plurality of vertically spaced substantially channel shaped members connecting said vertical portions, said sheathing being secured to said posts through said vertical portions, the legs of said channel shaped members extending outwardly from the plane of said wall.

4. A metallic wall structure for railway cars, trucks, containers and the like, comprising metallic posts, metallic sheathing extending between and secured to said posts, said sheathing embodying a plurality of integrally formed sheathing units, each unit including vertical intermediate and end members, vertically spaced horizontal members extending between said vertical members, the outer margins of said end members being substantially plane and the margins of said vertical members between said horizontal members and the margins of said horizontal members being flanged outwardly, said end members of adjacent units being overlapped and means fastening said intermediate and end members to said posts.

KNUTE EDAHL.
