w it known that l, l'iiv'ron citi/,en of the United States, residing at Chicago. in the county oit Cook and State ot illinois. have invented certain new and useful Improvements in Railway Cars. oi' which thc following is a specification.

My invention relates to railway cars. and has for its object to provide a new and iinproved car end .structure which will have the necessary strength and rigidity to withstand the variousl stresses to which the end walls ol' railway 'tre-ight ears are subjected when in service, 1Where the contents of a car consist ot' grain or other material in bulk ot the character usually loaded in. box cars, or it the material is of the character usually loaded in gondola cars1 for example, coal, crushed stone. or the like. the greatest stress imposed on the end walls ot the car is in the region of the lower halt ot the wall. This portion ot the `end wall. is also subject to severe stresses incident 'to the inertia thrusts ot' the-cargodue to the sudden starting` or stopping` ot the car. part-icalarly when the cargo consists oitl heavy niovable objects. such as railroad rails. or car wheels. Accordingly it is an object ot iny invention to provide a car end 'structure which is so formed and Y 1 it reinforced as to be strongest in the region oti such other incidental objects as will appear from the following description.

ferred embodiments in the accompanying drawing. wherein- Fig: 1 is an elevation ot an end wall structure made in accordance with my invention7 applied to a. gondola car;

Fig. 2 is a vertical section taken on line 2 2 or rig. i.

Fig. 3 is a fragmentary View in section of the corner construct-ion ot' the end wall shown in Fig, 1, this view being taken on line 3-3 of Fig. 1, and

Fig. et is a view similar to Fig'. 23. illustrating a iuodified'torni ot end post.

Like characters of reference indicate like parts in the. several figures of the drawings.

ln the drawings I have shown rny irn- Serial No.. 462,147.

proved car end Wall structure in connection with a car of the gondola type, though the principles disclosed could obviously'be embodied in an end wall structure suitable for hox cars.

Referring irst to Figs. l to 3 inclusive of the drawings, l() designates the side sills, 1l 'the side walls. l2 the corner posts, and 13 the flooring of a gondola. air. The end wall of the car consists. preferably, of a single metal sheet lsl- `formed with a plurality of parallel corrugations 15 which extend horizontally across the end and terminate within the edges oit the sheet. so as to provide flat inarginal portions 1G. The corrugations project outwardly from the plane of the sheet and preferably increase in depth uniformly from the top to the bottoni of the sheet, so as to provide the greateststrength adjacent the lloor of the car. Theflat marginal portions 1G adjacent the vertical edges of thesheets are bent at right angles to the body portion ol the sheet to provide attaching flanges 17 which overlap the outer surfacesof the sidey walls ot the car and are lirmly secured to the corner posts by bolts 18. 19. The lower Inargin ot the sheet is secured to the end sill 20 by rivets 2l. By providing the end sheet 14 with corrugations having the greatest strength adjacent the floor of the car. it is possible to use a relatively light end sill and thereby minimize the weight ot' the car without sacrificing the strength and rigidity necessary to provide a irm attachment of the end sheet to the under framing of the car. and to maintain the side and draft sills of the under 'framing in their proper alignment. rl`lie end sill Q0 is illustrated in Figs. l and 2 as consisting` of an angle bar arranged with its vertical flange Q2 against the outer face of the sheet and its horizontal flange Q3 secured by rivets Q4; to the Side sills l0. The end sill may be similarly secured to the draft sills and to intermediate sills when the latter are employed.`

ln order to provide further reinforcement for the end structure adjacent the corners 'ot' the car, I preferably provide vertically extending angular posts 25, which are provided in each case with a flange 26 which overlaps and is secured to the sidewall of the car, and with a flange 27 which overlaps the extremities of the co-rrugations 15. The

lianges 27 of the angular postsare preferablyI Renewed may 31, i921, serian No." ivided and this application filed April 18, 1921.
