To all whom it may concern:

' strong andrigid so as to be capable of withstanding shocks and pressures, for example, the inertia thrusts of shifting cargoes, and so as to' act as a reinforcement for the car superstructure as a whole, and which may be manufactured and installed more economically and conveniently'than the sheet metal ends heretofore employed in the construction or repair of railway cars.

Having in view particularly the hard usage to which the ends of freight box cars are subject due to shifting cargoes and like causes,'cars of this sort have been equipped,

either in their'original construction or in the repair of broken ends, with end structures consisting of one or more sheet metal elements formed with horizontal ribs or" pressed corrugations which carry the stresses exerted thereon as beams to the corner posts l of the car.

. The primary object of this invention is to provide a car end-structure, suitable for use,

either in the constructionof new cars or for repalr purposes, consisting of a plurality of metal end sheets extending from substantially the roof of the car to the floor, suitably joined together and to the corner posts of the car along their vertical edges and provlded with vertically arranged parallel corrugations extending substantially from the top to the bottom of the structure so as,

in eifect, to form upright load carrying members which help to support the roof and M a which serve to rigidify and strengthen the end wall of the car and thereby the entire frame members of the car.

The invention has for further objects such Specification of Letters Patent.

Fig. 1 is a view, inperspective, of the upper attaching and rigidifying member, and Fig. 5 is a similar view of the bottom attaching member. p

The ear end is shown for purposes of illustration as, applied to a wooden box carof standard construction. The wooden" end plate of the car framing is designatedIO, the

The end structure in the preferred form shown is composed of a corrugated panel consisting of two sheet metal elements 16, an upper rigidifying and attaching member or metal end plate element 17 (Fig 4:)" and a lower angular rigidifying and strengthening member 18 (Fig. 5). The end sheets 16,

16 are formed with vertical corrugations 19 which extend across the'sheets from top to bottom, that is, from the upper to the lower edges thereof. The sheets are formed on their outerlateral edges with angular flanges 20 which are secured to'thecorner posts 12 by any suitable means, for efXample, the bolts 1 i 21. The meeting edges of the sheets 16fare preferably provided with angularly disposed flanges 22 fastened together by rivets 23.

The top member or metal end plate 17 is se- 1 cured to the wooden end plate 10 by'bolts 2 1, or other suitable attaching devices and has flanges 17 (Fig. 4) overlapping and'secured to the side wall of the car. Thelower edge of the top member overlaps the upper g,

edge of the panel 16, 16 and has a corrugated or undulatory configuration correspending with the corrugated configuration o'f the panel. The panel and top memher are secured together preferably by iey,
