To @ZZ whom z5-may concern:

Be it knownthat I, VINToN E. SIssoN, residingat Chicago, county .of Cook, State oflllinois, and `being. a citizen of the United States, have invented certain new and useful Improvements in Corrugated` Valls for Railway Cars, of.` which the following is a full, clear, and exact description, such as willenable others skilledin lthe art to which .it appertains-'to make'andtouse the same, referencebeing ,had tothe accompanying drawings, which illustrate the preferred form of theinvention, though it is to be understood that 4the invention is not limited to theaexact details of construction shown and described, as it is obvious that various imodications :thereof within the scope. of the .claims will occur to vpersons s'kil'ledin the art.

The ends of railway cars are subjectV to considerable stress due to the shifting ofthe lading which is caused bythe heavy loco-v '.motives, .the automaticv air brake, -the hump and other modern .railway service conditions.

"llhese .thrusts may be local, tending to distort the end in somelparticular spot, as, for example, when a ,piecee'f pipingy or lum- .ber .shifts lengthwise, or a load ,of plastic '.material, such as grain, -sand .or chats may shift, imparting a blow over a-large area off the end well, whereas rail, steel plates, castngsand the like cause. 'blows at the bottom `of .the car. YFrom the above, it .is apparent that a railway car end must be strong throughout its entire area. 'i Experience .sho-ws .thata stronger end wall is neededadjacentlthe floor of the car becauseJ the blows .against this Iportion Aof 'the car .wall are .more frequent and more severe than at the middle or .upper portion thereof. Very littleJ strength is .neededadjacent .the top of the .carrwall and the strength y'required at the middle ofthe car Wall is more than needed at the topaand. .less than :needed .at the bottom.

While, of course,.efforts'are made to block the lading in the fcar, the yshocks .caused 'by the heavy locomotives,..the emergency air brake andthe classilication lhump tear the .lading away-trom its `moorings andthrow it against the side walls oftheucar.

weaving movements which notonly rack the car to apieces,but causes leaky roofs and in- .operative and llealry doors with their consequent damage claims. As 4it costs'as muchto transport a ton offreight caras it does a ton ofllacling itis imperative that the weight o'f the car must be kept as low"l as possible, there`fore,ltlie end must bev very light as Swell as strong. As freight cai-sare frequently damaged in wrecks and by,v other unfair usage, anyy .end ywill probably -be I damagedin service, therefore, it-mnstbe capable o'fbeing .easily repaired with such meagre facilities'as therailroads are equipped with at y their outlying repair po-ints. p

My linvention relates to the construction of'ra'ilway cars and more ,particularly to metal end -structures'or walls for'railway Icars made of one or more metallic plates or panels formed with integral reinforcing stitfening or bracing corrugations; However, (the construction maybe used in'car side walls. Itis readily adaptable ytol'boX,

gondola, stock or vother types ofrail'way equipment. p v .q

All metal car ends 'have been made fof corrugated metallic plates secured together lhaving the centers of adjacent corrugations .equally spaced apart.

One of the ob'ec'ts o fmy invent-ion .is to provide a metallicend wall made of one `or q more Imetallic `plates with reinforcing cor- .formi-ng .the corrugations deeper and .wider adjacent the floor.

Anotherobject of .myinventionisto space the corrugations so that the end wall .is Astn'engthened ,according to its requirements, but at the sam@ time, the corrugations .are

maintained at the same depth. throughout theentire endwalh This has the advantage of ,not yincre'asing .the length. ofthe car over the .end wall-for decreasing the inside 'length of the car. l'lhe thickness .of the endy wall ,is maintainedconstant throughout. A'. further object is to provide aI terraa gated metallic wall element which it is practically possible to manufacture and easy to apply and secure to the car.

The distance between the centers of aidjacent corrugations increase from the lower to the upper port-ion of the wall; in other v words; the distances 'between thecentersof adjacent corrugations near the floor of theV spacing car are less than elsewhere.
