RAILWAY CAR WAIQI..

Application ined December My invention relates to the construction of railway cars and more particularly to metal vend structures' orI walls for railway cars made of One'or more` metallic plates o'r panels formed with integral reinforcing,

.stiening and bracingembos-sments orrorrugations However, this device maybe incorporated in the construction of car side lwalls, floors, roofs or doors used in connec- 1o tion with yrailway cars ofvvarious types.v

Itis well known that the .end walls of raili'vay box cars are more likely to be broken or otherwise injured than the side walls. This is due to the inertia thrusts and presi5 sures 'caused by the shifting of the cargoes when the .train starts or stops.' These thrusts may be local, tending to distort the end in some particular spot, as, for example, when a piece of piping or lumber shifts lengthwise imparting a blow against the end wall of the car; "orthere may be a general tendency to break out the end wall a whole or tear it away from the framing. For the purpose, therefore, of greater strength and durability, car ends have been constructed of metal plates cOrrugate-d or formed with rib-s to impart lthe desired strength, rigidity and resiliency.y I

One of the principal Objects of my invention is to provide a corrugated metallic end structure for railway cars in which the corrugations lhave a configuration and arrangement thatV impart to the structure a j maximum capacity for resisting cargo thrusts, both local and general, 4static or quiescent, and with sufficient resiliency to I prevent permanent distortion cue to the thrusts of the loads, with a minimum weight of metal. lt is important that structures of this sort should be as light is possible, consistent with strength and durability, both forreasons of economy in manufacturing cost and also to keep the weight of the car ata minimum.r f

The retaining walls of railway cars are lined to retain the cargo within the car, because a riveted joint between twoflat vsteel surfaces will not retain such fine lading as grain, sand, etc. Steel frame (and even wooden) cars are lined with wood which absorbs moisture and retards sweating. If grain was allowed to Contact with a lsteel wall the consequent condensation of the moisture in the atmosphere would cause mildew, and in such ladings as cement and 7 y199.55. 'Seriana 73,834.

flour (even though sacked) such moisture would cause lconsiderable damage. "A wooden--liningv between the 4steel lwall and the'lading' practically eliminates such condensation. yAc wooden lining'also furnishes excellent vmeansv for blockingbulky and package lad--`rk ing in place. 7

Any lining necessarily increases the thickness ofl the wall;vr and in an end wall this means that the inside length of the car is reduced or the trainlength of thecar vis increased, either of which is objectionable. lt is desirable, therefore, to provide `as thin a llining las] possibleV consistent lwith require- `ments andk to support 'the lining by means which occupy thef minimum possiblev :hori
