4 Claims.

The invention relates to end walls for railway cars which are made of metallic plates or sheets formed with a plurality of substantially parallel and sinuous corrugations to provide a plurality of beams extending between the opposite side walls of the car so as to transmit horizontal loads imposed thereon, such as caused by a shifting load, to the side walls of the car. Such a construction is generally shown in the patents to 1g) Small, No, 1,681,811 and No. 1,681,812 of August The sinuous corrugations open up under stress like an accordion pleat, thereby giving resiliency to the end wall structure. This yielding causes a bulging of the structure which pulls the corner posts of the car inwardly or toward each other, and as these corner posts are rigid frame members of the car, they are necessarily quite stiff, therefore, such inward deflection frequently gives them a permanent set, thus preventing the bulged end from returning to normal position.

One of the objects of the invention is to provide flexible means between the usual corner posts of the car and the corrugated metallic end wall so that when the corrugated end wall is deflected under a horizontal thrust, the means will flex or yield without disturbing or distorting the corner posts and furthermore so that the corrugated end wall will return to normal position without permanently distorting any of the car parts associated therewith.

Another object is to attach such flexible means to parts of the car so that the relative flexibility of their middle and end portions is substantially commensurate with amount of exing caused by the relative amount of bulging of the corrugated end at the middle, top and bottom thereof.

In the drawings:

Fig. 1 shows the end of a railway box car equipped with my improved device.

Fig. 2 is a section on line 2-2 of Fig. l.

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

Fig. 4 is an enlarged section on line 4--4 of Fig. 1.

Figs. 5 to 1l inclusive show modified constructions.

The drawings show the usual Z bar corner posts 2 and side wall sheathing 3 and lining 4 which form a part of the side truss to carry part of the weight of the lading and the car to the body bolsters and which also resist the lateral thrust of the lading when the side wall acts as a retaining wall, therefore, the posts must be very strong and rigid. Each post is secured to the side plate 6 of the car and also the side sill 1 of the car.

An extension plate l0 is secured to each side wall, preferably to the corner postA 2, and has a portion Il extending beyond the corner post and in substantially the same plane as the side wall and provided with a return ilange I2 portion. 5 The extension plate lis preferably attached to the side plate 6 and side sill 1 of the car.

The metallic end wall I5 sheet is formed with a plurality of parallel corrugations I6 which extend to the opposite edges of the sheet. The edges of 10 the metallic end wall sheet abut the return flanges l2 of the extension plateand arefsecured thereto preferably by welding l1,

In this arrangement when the -end wall deflects outwardly the bend in the extension plate opens l5 up or fiexes and the portion of the extension plate also distorts, thus providing a resilient flexibility.

Under horizontal load the corrugations in the end wall will open up and allow the end wall to, deilect and the greatest deilection will occur sub- 20 stantially midway between the top and bottom of the end wall and consequently the yielding or the pull in of the extension plates will be greater substantially midway between their tops and bottoms than elsewhere. In other words, my 25 constructions allow the extension plates to yield commensurate with the yielding of the end wall. Furthermore, as the tops and bottoms of theextenson plates are anchored they offer some resistence to deflection thereof which tends to re- 30 turn the extension plates and the end wall to normal positions.

Fig. 5 shows an extension plate 3D extending substantially in the same plane as the side Wall 3 to which the corrugated end Wall 3l is secured. 35

Fig. 6 shows an extension plate 35 having a flange 36. The corrugated end wall 31 is welded to a flat end piece 38 which in turn is riveted 39 to the extension plate 35 under the ange 36.

A plate formed with corrugations extending to the 40 opposite edges thereof is quite flexible so the end piece 38 holds it in shape while being attached to the extension plate.

Fig. '7 shows the extension plate 40 parallel to and in contact with the end piece 4l and secured thereto by welding 42, These members may also be welded together at 43.

Fig. 8 shows the extension plate 45 formed with a corrugation 46 lengthwise of the extension plate I and having a flange 41 corrugated to register with d the corrugations of the end Wall sheet 48 and secured thereto 49.

Fig. 9 shows an extension plate 55 formed with a lengthwise corrugation 56 on' the side of the 55 car and also a corrugated ange 51 fitting the corrugations of the end wall sheet 58.

Fig. 10 shows an extension plate SB formed with an offset portion 6l and a shoulder 62 with the end wall sheet 63 secured to the oiset portion 6|.

Fig. 11 is similar to Fig. 10 but shows the extension plate 65 connected to the oiset portion 66 by large radial portions 61. The end wall sheet 68 is attached to the oiTset portion 66.

In my copending application I have disclosed and broadly claimed means for flexibly attaching a corrugated end wall sheet to the side wall or corner posts of a railway car, whereas in this application I claim a modication thereof wherein the corrugations in the end wall sheet extend to the opposite vertical edges of the sheet, thus necessitating a different method of attachingY the corrugated end wall sheet to the flexible exten-V sion plates.

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.

1. In a railway car having spaced apart corner posts and a side wall secured to each post in combination with a flexible extension plate secured to each side wall and having a' portion extending therebeyond, and a metallic vend wall sheet formed with a plurality of corrugations extending between the opposite edges of the sheet and secured to said portions of the flexible extension plate so that when the corrugated end sheet deflects under load the corner posts will not be distorted.

2. In a railway car having spaced apart corner posts and a side wall secured to each post in` com bnation with a flexible extension plate secured to each side wall and having a portion extending therebeyond, said plate being bent to form a return flange, and a metallic sheet end wall formed with a plurality of corrugaticns extending between the opposite edges of the sheet and secured to said return anges of the extension plates.

3. In a railway car having spaced apart corner posts and a side wall secured to each post in combination with a exible extension plate secured to each side wall and having a portion extending therebeyond, each of said portions having a part offset from the plane of the side wall, and a metallic end wall sheet formed with' a plurality of corrugations j extending between vthe opposite edges of the sheet and secured to said offset parts of the flexible extension plate.

4. In a railway car having spaced apart corner posts and a side wall secured to each post in combination with a exible extension plate secured to each side wall and having a portion extending therebeyond, a metallic end wall sheet formed with a plurality of corrugations extending between the opposite edegs of the sheet, and a member abutting each' end of the corrugations and secured thereto, said members being secured to said portions of the flexible extension plate.
