To all whom it may con/cem:

Be it known that LIVIN'roN ESISSON, al citizen of the United States, residing at Chicago, in Illinois, ful Improvements in Railway-Car End Walls, of which the following is a spec'cation.

My invention relates torailway cars, and has for its object to provide a new and improvedA end structure for a' railway car which will have very considerable strength and rigidity soas to be able to withstand the various stresses to which the end walls of railway freight. cars are subjected when in service. Where the'contents oi the car consists of, grain -or other material in vbulk ofthe character usually loaded inbox cars, or if the material is of the .character-usually transported'in gondola cars, as, for-example, coal, crushed stone, or the like, the greatest p stress imposed upon the end walls of the car is in the region of the lower half of the wall. This portion of the end wall is also subject to severe stresses incident. to the inertia thrusts of the cargo due to sudden starting and stopping, particularly when the cargo consists of heavy-movableobjects, such as railroad rails, car wheels, pipes, or the like.

The principalobjectof my invention is to provide a car end structure which is so formed and reinforced as to. be very considerably stronger in the lower portion thereof where the stresses are liable tobe greatest. v

- The invention consists in the' novel arrangements, constructions and combinations of parts, to be hereinafter described and claimed, for carrying out theabove stated objects and such other incidental objects as will appear from the following description of the preferred embodiment of the invention-shown'in the accompanying drawing, wherein- Fig. 1 is a fragmentary view, infelevation, with a part in section,.of the gondola car f end wall 'constructed in accordance with my invention, I

2-2 of Fig. 1, and

the county of Cook and State bfhave invented certain new and use- Y of the sheet is Ibent over to form Fig. 2 is a vertical lsectional view on line 50 Fig. 3 isa detail sectional plan on line 3-3 of Fig. 1. y Like characters of reference indicate like parts in the several figures of the drawing. Referring to the drawing, the end vwall ofthe car as shown consists'of a sheet of metal 10 provided with a series of inwardly pressed corrugation's 11, 12, 13 and 14, which are progressively greater incross sectional area, .width anddepth, thatvis, from the top of the sheet to the bottom. The upper edge an inwardly projecting iiange 15 which is rigidied by means of an angle bar 16. The end sheet' 10is secured to each' side wall 17 by a pair of angular members 18,' 19. The member 18 is slanted, as shown in Fig. 2, to accommodate for the increasing depth of the corrugations toward the bottom of the sheet, is secured to the side wall 17 by rivets 20 and is anchored to theside sill 21 of the car by means of la gusset plate 22. 1t' is secured to the end sheet 10 by rivets 23 and is also securedby rivet 24 to 'the upstanding flange 25 of a Z-bar 26 which, in the construction 'f5 shown, forms the end sill of the car. The

flange 27 of the attaching member 19 is'se-v l cured to the side wall 17 by rivets 20, before mentioned. The other flange28 of member 19 is formed with depressions or corrugations 29, 30, 3'1, 32 adapted to`t the corrugations 11,12, 13 and 14 of the end sheet. The latter preferably extend. to the edges of the sheet although this is not essential. Flange 28 is secured to the end sheet by a line of rivets 32.

' A- car end constructed as shown 4is eX- i tremely strong and rigid so as to withstand the Vstresses to whichv the end of a railway car is subjected. The lower portion of the wall is considerably stronger than the upper portion so that the end is well calculated to withstandboththe greater hydrostatic presljsure lat the bottom of the car, when the car is loaded with bulk material, and also the 95 greater stresses resulting from theshifting of heavy articles of lading, such as rails, pipe, andthe like, which stresses are more likely to be exerted against the bottom of the end than the top. The end may be constructed at low cost since the sheet may be corrugated by a rolling or other cold process of bending. rllhis is possible because of the fact that the corrugations extend to the edges of the sheet.

This application is a division of my copending application Serial No. 197,107 filed October 17 1917, renewed as Serial No. 473,779, filedMay 31, 1921. e
