Application ledrMay 18, 1925. Serial No. 31,7144.

My invention relates to improvements in railway car construction and particularlyy to a novel method of forming carwall ele- -nients of railway cars. 5

An object of theinvention is to construct the wall elements ofrailway cars in such a manner that portions thereof will be rigiditied at the point of greatest strain by meaningless corrugations of great strength and other portions of the said.y wall elements where the strain is not so great will be rigidiiied by the incorporation Vof embossments defining descriptive characters, .indicia, symbols or designating markings whereby the car may be readily identified and an advertising value derived from the of such embossments. n f

@ther objects of the invention will more lclearly appear from the description hereinafter following.

ln the drawings forming a part of this specification, Fig. 1 is an end elevational view of a box car having` my improved construction incorporated therein. Fig. 2 is a sectional view taken oir-a line correspondinff substantially to line 2 2 of Fig. 1. 3 is a side elevational view of the side of a railway box car embodying my improved car construction. F ig. l is a sectional View taken on. a Vline corresponding substantially to line of Fig.

Referring first to the constructionshown in Figs. 1 and 2, l have shown my improvements as applied to the end wall of a box car. In said drawings the endwall is shown Y as composed of upper and lower panels designated broadly A. and B respectively. Each of said panels lis flanged at the respective side vertical margins afs indicated at 10-10, said langes preferably constituting the cornerposts of the car andl forming a suitable rigidifying means whereby the end wall is suitably` attached to the cor'- responding side walls ofthe car, The lower margin of the end wall is suitably rigidilied by a beam 11, preferably of angle shape, which extends horizontally between the side walls of the car and adjacent its upper margin the end wall is rigidified by a horizontally extending beam 12, preferably formed of Z-shaped section. The lower panel B has embossed therein a plurality of horizontally extending contiguous corrugations 13 which serve to resist bulging of theend wall intermediate the vertical margins thereof. The upper panel .A slightly overlaps thelower panel B and the parts are united adjacent the upper corrugation of said panel B by means'of a row of rivets as indicated at 14, and each of the vertical flanged margins 10 at the sides of the'upper panel A is'crimped over the corresponding vertical marginal flange of the lower panel B for the purpose of presenting a flush sur-- face onthe inner face of the said flange 10 where the side' wall of the car is normally disposed. Said upper panel A carries a descriptive symbol 15, which is 4preferably* formed by embossing a portion of the plate to form a rigidifying means adaptedto reinforce the panel against bending on `various cross-lines. Said designating symbol 15 is preferably characteristic of-a railway trade mark and serves as a perpetual designating mark in addition to providing great strength and rigidity in the wall parts; .lhe symbol 15 in the particular application illustrated herein includes a border having horizontally extending corrugations 16--16 and vertical corrugations 17-1C/- and the body of the plate intermediate the border is rigidied against buckling by the inclusion of letters as indicated at 18. The usual wooden sheathing within the car is indicated at 19, said sheathing being preferablv spaced from the metallic panels by means of battons as indicated at 2O and 21 respectively,

Referring now to the construction shown inFigs. 3 and Ll, I have shown my .improvementsl as applied tothe side door of a car, the framework of the door being indicated by verticalvk marginal members 110-110,

upper horizontal marginal member 111 and lower marginal member 112. The `main body of the'door includes lower and upper panels as indicated at C and D respectively.

vSaid lower panel C is secured to the vertical margins 11o-110 as indicated at 113 and to to the lower panel and to the upper horizontal marginal member 111 as indicated at 117 and 118 respectively. Said panel D has embossed therein the descriptivesymbol 119 which is formed to resist bending of the plate on various cross-lines.

The two embodiments of my invention as illustrated herewith are typical examples of preferred construction for the vertical wall elements of railway cars and while I have shown the symbol in the upper portion of the panel, this arrangement may be modified in any suitable manner. The disposition of the corrugations at the lower portion of the panelling is a preferred arrangement inasmuch as the tendency to bulge is generally greater at the lower part of the car wall than at the top thereof and the series of horizontally extending corrugations provide Y for great strength intern'iediate the vertical margins of a panel and it is also desirable, in order to secure sharpness of'delinition in the parts of the symbol, that the plate in which said symbol is embossed be as thin asthe strain on the car wall will consistently permit. Consequently the use of horizontal corrugations at the lower portion of the panel and the symbol at the upper portion thereof permits the use of a lighter plate for the upper portion of a panel.

Although I have shown and described a preferred manner of carrying out'my invention, the same is merely illustrative and I contemplate all changes and modifications that come within the scope ofthe claims appended hereto.

What I claim is:

1. In a car wall element including a panel of sheet metal, said panel being strengthened within its margins by embossments delining intelligible indicatory characters and a rectangular embossment disposed outwardly of said first named einbossments, said rectangular embossment being disposed inwardly of the edges of the sheets and provided with extensions adapted to continue the reinforcement beyond the main portion of said rectangular embossment.

2. In a car wall element the combination of a panel of sheet metal, said panel being strengthened within its margins by embossments defining intelligible indicatory characters and a rectangular embossment disposed outwardly of said first named embossments, said rectangular embossment being disposed inwardly of the edges of the sheets and provided with extensions adapted to continue the reinforcement beyond the main portion of said rectangular embossment, said extensions decreasingv in width and outline surrounding said symbol, said outl line being disposed an appreciable distance from the margin of said element, and integral embossments extending outwardly from the corners towards the margins to reinforce the plate intermediate the margins and the continuous outline.

4. In a railway car element, the combination of a main body portion formed of sheet metal said element beinoformed with a 3lurality of corrugations extending intermedie ate the vertical margins to reinforce the plate intermediate said margins, said corrugations being spaced apart an appreciable distance and having other corrugations embossed thereon disposedk substantially at right angles to the lfirst named coi'rugations but spaced inwardly from theends thereof; said vertical and horizontal corrugations together presenting the appearance of a rectangular framework and intelligence conveying characters embossed4 out of the main body of the plate for the purpose of reinforcing the said plate intermediate the panel. Y

5. In a car wall, the combination with horizontally extending beams disposed re` spectively at the upper and lower margins thereof, of vertically extending reinforcing marginal flanges formed on the wall and extending substantially between said upper and lower margins, a plurality of substantially horizontally extending corrugations in the lower portion of the car wall and constituting beamsextending between the respective vertical margins; and rigidifying means adapted to rigidify the upper portion intermediate said lower portion and top marginV of the car wall, said means including an embossment representing a rectangular framework forming horizontally and vertically extendingbeams and intelligible indicatory characters embossed within the said framework to strengthen the plate intermediate the framework.

In witness that I claim the foregoing have hereunto subscribed my name this 15th day of May, 1925.

ARGYLE CAMPBELL.
