corporation of Dela- Application April 24, 1942, Serial' No. 440,279 12 Claims. (Cl. 1054-4410) `This invention relates to railway cars and partlcularly to end walls of cars adapted to haul bulk commodities, such as gondola cars and hopper cars. The walls of such cars are made of single thickness material and consequently have no lining toassist in retaining the lading.

A common type of railway car end wall is comprised of a metallic plate formed with substantially horizontal corrugations which terminate adjacent the corner posts of the car. Many newtypeA cars embody an improved end wall wherein the vertical margins of the end wall plate arerilanged on a relatively large radius and the corrugations extendat least partially around the flanges to strengthen the corner posts. Such a construction is disclosed in the patent to Jumper, etal, No. 2,185,168 of December 26, 1939. A large number of box cars have been built with end walls substantially as shown in this patent and have given satisfactory service.

The above mentioned open top cars, such as gondola cars and hopper cars, are not provided with lining and the lading is retained by the outer metallic sheathing. The provision of corrugations in the end walls creates openings between the outwardly projecting corrugations and the corner posts which permit the lading to escape into the hollow post and outthe bottom of such post.

An object of the invention is to provide an end wall which embodies the advantages of the above mentioned round corner construction and which also embodies means to prevent the escape of lading from the car.

Another object is to provide means for preventing the escape of lading as herein above described without decreasing the strength of the end wall.

Other objects and advantages of my invention will be apparent from the following detailed description by referring to the accompanying drawings.

In the drawings: Fig. 1 is an end elevation of a railway car showing one embodiment of my invention.

Fig. 9 isa section on line 9 9 of Fig 8.

The drawings show the usual parts of a railway'gondola car including center sill 2; striking casting 3; side sills 5; end sill y6; side chordsrB; end chord 9 and side sheathing II. The corner post members I2 extend between and are secured tothe sills and chords and the wood floor I4 is supported by the inwardly extending legs I5 of the side sills 5.

A corner post member I2 is formed with angularly disposed arms 2li-2| arranged respectively normal to the side and end walls of the car and the arms 20 2I are preferably provided with flanges 23 24, the flange 24 including a flat surface. The end wall plate 26 is formed with large radius flanges 2l on its vertical margins, the plate franges 2l bein-g secured to the flanges 23 of the corner post members and the body part of the end wall plate 2B being secured to the anges 24 of the corner post members I2 to form hollow corner posts 29.

The end wall plate 2'6 is formed with a plurality of inwardly (30) and outwardly (3|) projecting substantially horizontal main corrugations which terminate and merge into the flat portion 32 of the end wall plate 26 which portion is secured to the ange 24 of the corner post member I2 in engagement with the nat surface thereof. The curved parts of the end wall plate flanges 21 are formed with a plurality of auxiliary corrugations 33 which extend around the corners and merge into the portion 32 of the end wall plate 2B which are secured to the corner post member flanges 24. The ends of the main (30 3I) and auxiliary (33) corrugations overlap so as to transmit loads from the end wall plate 26 to the corner posts 29 and so as to cause the corrugations 30 3I to function as partially restrained beams. 'I'he portions 32 of the plate 26 into which the main (S0-3l) and auxiliary (33) corrugations merge are uninterruptedly engaged with the flanges 24 of thecorner post members I2 to prevent escape of lading from the interior of the car.

Fig. 7 shows a modified construction in which the flange 3l of the corner post member 38 is relatively wide in order to provide greater overlapbetween the main (3U-3|) and auxiliary (33) Vcorrugations and thereby strengthen the connection between the end wall and the corner post.

In the modification shown in Figs. 4 to 6, the corner post members I2 are similar to those described with reference to Figs. l to 3. The end wall plate 40 is formed with a plurality of inwardly (4|) and outwardly (42) projecting substantially horizontalV corrugations which terminate and merge into uncorrugated marginal portions 43 which are secured to the anges 24 of the corner post members I2. Such marginal portions 43, therefore, have uninterrupted engagement with the flanges 24 of the corner post members, thereby preventing escape of lading from the interior of the car.

Auxiliary plates 44 formed on curves of relatively large radius are secured to the corner post members I2 so as to form hollow corner posts 46 and have portions 41 which overlap and are secured to the end wall plate 40. The auxiliary plates 44 are formed with a plurality of corrugations 49 which extend around the corner of the car and terminate in interlocking relation with the end portions 50 of the corrugations 4I-A-42 in the end wall plate 40. tions 4| are thus effectively extended aroundthe corner of the car with the resultthat thrusts upon the end wall are more completely transferred to the corner posts 46 and the corrugations are caused to function as at least partially restrained beams.

Figs. Band 9 show a modied construction in which the corrugations 55 in the auxiliary plate 56 nest with and are secured to the outwardly projecting corrugations 5B in the endlwall plate 59 to more effectively secure the ends of the corrugations to the corner posts 6l and to cause the corrugations 5B to function as `atleast partially restrained beams. The corrugations 58 terminate and merge into an uncorrugated portion 62 of the end wall plate l5i) whichV is uninterruptedly engaged with and secured to thefiange 24 ofthe corner post member I2 to preventescape of lading from the interior of the car. v

The accompanying drawings illustrate the 'pre- Vferred form of the invention, though itis to be understood that the invention is not limitedv to the exact details of construction shown-and described, as it is obvious that` various modiiications thereof, within the scope ofthe claims, will occur to persons skilled in the art.
