3 Claims. (01. 105-409) The invention relates to railway freight cars of the panel is ofi'set relative to the marginal and more particularly to side and end walls for portions for certain advantages pertinent to the open top railway cars, such as hopper and gonparticular article for which the panel is used and dola cars, though the construction is adaptable wherein certain sides of the panel comprise stif- 5 for walls of house cars, such as box, automobile fening means which strengthen the ofiset body 5 and refrigerator cars. The construction is also portion, form means of attachment of the panel adaptable for use as roofs, floors, hopper doors to other parts of the car or to similar panels and side doors for railway cars. A roof or a when associated therewith.

It is desirable to make the reducing the amount of cubic feet occupied by inside horizontal width of the car as wide as the stake so that the stake reduces the cubical possible to increase the cubical capacity of the lading capacity of the car to minimum amount.

In the drawings:

Another object is to provide a panel of novel combine to form a very strong post or column construction wherein the body or main portion between the upper (2)and lower (3) chords and 55 also combine to form a very strong beam between these chords 2-3 to resist horizontal thrust of a plastic lading. The end marginal parts 8 of the wall sheets are secured to the upper and lower chords, respectively, by welding 2|, as shown in Fig. 5, or by overlapping the riveting, as shown in Fig. 2.

The central portion I 2 of each sheet is positioned below the-plane of the top l3 of the corrugations 9 to form a bead24 for stifiening purposes and so as to protect the lettering on the car which may be stenciled on the central portions I2 of the several plates.

The outer parts of tops l3 of the corrugations 9 are preferably positioned flush with the outer edges 25 of the chords and the central portions l2 of the wall sheets are positioned as near thereto as possible and still obtain the advantages enumerated herein whereby the cubical capacity of the car is decreased the minimum amount.

In the wall sheet described the parts are so proportioned and arranged that the length of the center line of the metal of any horizontal cross section from side to side of the wall sheet is the same as any other cross section parallel thereto so that the plate while being formed between reciprocating dies is 'bent and not stretched. Thus in my design of wall sheets relatively thin plates may be pressed cold and relatively thick plates may be pressed with very little heat. Local stretching of a metallic sheet while being formed reduces its resistance to corrosion by disrupting the metal.

The lower connecting portion l5 merges into the end marginal part 8 above the top of the lower chord 3 so that lading will be discharged freely and also the upper marginal part I6 merges into the end marginal part 8 below the bottom of the upper chord 2 so that the lading will be freely discharged when'the car is turned upside down in an unloading machine. (The drawings show a hopper car having hopper sheets28-29) Fillers 39 are used for closing the ends of th corrugations 9 above the top of the lower chord 3 and other fillers 3| are used for closing the ends of the corrugations 9 below the bottom of the upper chord 2. The interior surfaces of these fillers 30 and other fillers 3| are preferably flush with the interior surface of the adjacent connecting portions l5 and [6 to avoid pockets which would retain part of the lading in the car and cause corrosion.

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 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 an upper chord, a lower chord and a plurality of wall sheets; each sheet comprising side marginal parts secured to the side marginal parts of adjacent wall sheets, end marginal parts secured to said chords, respectively, spaced apart corrugations extending between and overlapping said chords, respectively, a central portion in a spaced apart plane from the side marginal parts below the plane of the tops of said corrugations and connecting portions between said central portion and said end portions, said connecting portions merging into said end marginal parts above the top of the lower chord and below the bottom of the upper chord.

2. A wall for a railway car comprising an upper chord, a lower chord and a plurality of wall sheets; each sheet comprising side marginal parts secured to the side marginal parts of adjacent wall sheets, end marginal parts secured to said chords, respectively, spaced apart corrugations extending between and overlapping said chords, respectively, a central portion in a spaced apart plane from the side marginal parts below the plane of the tops of said corrugations and connecting portions between said central portion and said end portions, said connecting portions merging into said end marginal parts above the top of the lower chord and below the bottom of the upper chord, and fillers closing the ends of said corrugations above the top of the lower chord and other fillers closing the upper ends of said corrugations below the bottom of the upper chord.
