the use of the endplate or end sill. When used in open top cars (gondolas) the corner post could be dispensed with. 1

Another object of the invention is to form a wall of a railway car of two plates secured together along a horizontal line and to form an integral post ad acent each vertical margin thereof and to reinforce the con- 7 nection between the two plates at each core ner post. I

-In the drawmgs: I 'Fig; 1 shows a'ra1lway Fig. 2is'a side elevation of Fig. 1.

Fig. '3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a perspective View of a metallic plate having an integral corner post formed thereln and reinforced according to my in vention. r

Fig. 5 is a modification of Fig. 1.

Fig. 6 shows-the plate of Fig. 5 without the reinforcement.

Figs. 1 to 4 inclusive show my invention 1 applied to a railway box car wherein the metallic plate 1 forming the end Wall of the car is provided with an integral Z shape mem-.

ber adjacent each of its opposite vertical margins, which members are secured to the upper side plates 2 and lower side SlllS 3, respectively, on each slde of the car, thus forming the usual corner post, that 1s, the integral Z shape formation or members performs the functions of the usual corner post of the car. (This construction is disclosed and claimed in my co-pending application Serial No. 308,102, filed September 24, 1928.)

would eliminate boxcar equipped V with a typical application ofmy device.

Each Z shape member comprises a web' l,

an outer flange 5 and an inner flange 6. Such a Z shape construction provides a very strong column to resiststresses longitudinally of its length, and furthermore, such a Z-shape conq;

structi'on forms a very efficient 'beam'to resist stresses normal to its length. This statement is true whether the stressesare parallel tothe web, normal to the web or diagonal thereto, therefore, such a Z shape for- '3;

mationforms a Very eflicient corner post construction. v 1

When a member'is subjected to columnar stresses or beam stresses, the maximum fibre stress occurs adjacent the middle of the memher, and as a co rner post (orin fact any post in'a railway car) is subjected to both of such stresses, I' prefer to reinforce the middle portion of the integral corner post with areinforcing sheet havinga portion secured to the body ofthe sheet at'8 and a portion secured to the outer flange at- 9 and a straight portion 10 connectingthe portions 8 and 9, as shown in Fig. 3. These reinforcing sheets may comprise a' plurality of narrow bands :15

11, as shown in Figs. 1 and2, or may comprise a relatively wide sheet 7, as shown in Figs. 4 and 5. g

I prefer to extend the reinforcing sheet or she'etslbeyond-the outer flange 5 of the L.

plate and secure them to the longitudinal. girths or other frame members of'the car, thus tying the end wall to thesegirths and furthermore tying the girths together.

In the opinion of some engineers it may i T be objectionable to have the diagonal portion '10 ofthe reinforcing sheet 7 spaced away from the integral corner post, as such a constructionwould'permit moisture or snow to get'behind the reinforcing sheet, therefore, in Fig. 5 I have shown a constructionwherein'the end portions 15 are extended and'formed to fit into the contour of the integral corner post, thus closing one (or both) oftheends of, the reinforcing plate.

I prefer to'seeure these extended ends to the web 4 by rivets 16 and inner flange 6 by rivets 17, respectively, of the Z shape corner post .to'seeureunity of action therebe-, M

tween under stress.

A great many car ends are now in service comprising an upper and lower metallic plate secured together along horizontal lines and having integral horizontal corrugations in each sheet and such sheets are secured along their vertical edges to the corner posts of the car which extend continuously from sill to plate of the car. WVhen an integral corner post is formed in such a construction (as shown in Fig. l) a weak place is formed where the two plates are secured together because the riveted connection is not as strong as other portions of the integral corner post, therefore, when the end wall comprises two metallic plates secured together along horizontal lines and form an integral corner post I prefer to so position the reinforcing sheet that it spans the juncture of the sheets and is secured to both of said sheets and the width of such reinforcing sheet could be extended to develop the strength of the integral corner postaccording to known methods of caiculating columns and beams. Vhen such sheets are provided with horizontal integral corrugations or embossments 19 I prefer to terminate them into the plate adjacent the reinforcing sheet, as shown at 20 in Fig. 4.

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 sho *n and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.
