Patented Sept. 16, 1930 UNITED STATES PATENT OFFICE ARTHUR E. SMALL, OF CHICAGO, ILLINOIS, ASSIGNOR TO UNION METAL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE METAL STRUCTURE FOR RAILWAY CARS OriginaI'appIication filed October 19, 1922, Serial No. 595,634. Patent No. 1,681,811, dated August 21, 1928. Divided and this application filed February 18, 1928. Serial No.'255,451.

My invention relates to the construction of railway cars, and more particularly to metal end structures or walls for railway cars madeof one or more metallic plates or panels formed with integral reinforcing, stiffening and bracing embossments or corrugations. Howeventhis device may-be incorporated in the construction of car side walls, floors, roofs or doorsused in connection withrailway cars of various types.

It is well known that the end walls of railwaycars are more likely'to be broken or otherwise injured than the side walls. This is due to the inertia thrusts and pressures caused by the shifting of the cargoes when the train starts or stops. These thrusts may be local, tending to distort the end insome particular spot, as, for example, when a piece ofpiping or lumber shifts lengthwise impartinga blow against the end wall-of the car; or there may be a general tendency to break out the end wall as a whole or tear itaway from the framing. For the "purpose, therefore, of greater strength and durability, car ends have been constructed of metal plates corrugated or formed with ribs to impart the desired strength, rigidity and resiliency.

One of the principalobject's of my invention is to provide a corrugated or embossed metallic end structure for railway cars :in which the corrugations or embossmentshave a configuration and arrangement that impart to the structure a maximum capacity for resistingeargo thrusts, both local andgeneral, static or quiescent, and with suflicient resiliency vto-prevent permanent distortion due to the thrusts of the loads, with a minimum weight of metal. It is important that struc tures of this sort should be as light as is possiblo consistent with strength and durability, both for reasons of economy in manufacturing cost and also tokeep the weight of the car at a minimum.

A further object is to provide a corrugated metallic wall element that is practically pos sible to manufacture. A'further objeotis to provide a metallic wall element with cornu- 'gations or embossments that resist to a greater degree torsional stresses, as well as brace the element, and the car end against diagonal side thrust-s or wearing.

Another object is to form a metallic plate with integral corrugations or embossments which impart to it a certain amount of strength and rigidity to resist Lloadsuniposed thereon and to so form the ends ofth'ezoonrugations or embossments as to provide a .certain amount of resiliency to enablethmpl'ate to deflect and return to its normal position without appreciable amount :of permanent distortion.

Referring :to Figs. 1 and 2,:the corrugated'or embossed plates or panels 1, Qand 3 extendacross the car from side to side and.

are formed withintegral flanges .4 along-the vertical edges wh ch overlap and are secured to the :frame membersof the side walls fi of the car by. any suitable means. The top edge are securedto the plates 1, 2 and 3 bybolts and lining 11 is secured to the nailing strips 10. While the corrugations or embossments are shown pressed outwardly from the original plane of the plate andin horizontal arrange ment, it is understood that the corrugations or embossments maybe pressed inwardly or partially-inwardly and partially outwardly from the original plane of the plate, or the corrugations or-embossments may be. placed in any position; :for instance, vertically or horizontally. The plates or panels may be applied to any'type of railway can I 7 Figs. 3 to 10 inclusive show thepreferred form wherein the plate is provided with a plurality of major corrugations or emboss= ments 20 with arcuate apices which are spaced apart distances substantially equal to their respective widths and the parts 21 of the plate between the majorcorrugations or embossmentsare also arcuate so that the confi'gura- 'tion is symmetrical in cross section about a line midway between the outermost portions iof-these ma or corrugations or embossments (see 5) which line is the neutral axis of the section. Suchaesection is very strong on'account of the amount of metalposit ioned gations or embossments 20 are preferably widest-and deepest adjacent their middle portion and decrease in width towardtheir opposite ends and the radii of thearcuate apices decreases toward .the ends :of the embossments. 7 The metalli'cplateis also provided with a plurality" ofaligned'minor corruga tions orembossments 24; which lie between adjacent ma or corrugat1ons or embossments' 20 withtheir inner end terminating intothe plate (-25) and with their outer-fiends terminating into the plate'in line with the outer ends of the major corrugations or emboss-,

ments.

3 The outer ends of the minor corrugations or embossments- 24 have arcuatev apices' and the parts-25 of the plate between the outer ends of the minor corrugations or embosss ments andthe outer'ends of the major corrugations or embossments are also'arcuate so that they form a cross section of sinuous con figuration, and, furthermore, the outer ends; of the'ina or and minor corrugations or em- 'bossments are equal 1n Wldtlr and spaced,

apart distances substantially equal totheir respective widths so that they form a contiguous sinuous configuration symmetrical in CIOSSSGCtlOil about a lmemidway between the outermost portions of the corrugations or embossments (see Fig; 7 which line' is the oppositeend portions former and is more neutral axis of'thesection. Such a section is very resilient and has a spring like action 7 under load, and, further, produces a "very strong section for theamount of metal used.

The major and minor corrugations or em-- j bossments merge ,into' the plane of the plate bymeans of terminal portions 26 of any desired formation. By such an arrangement a corrugated metallic plate is provided which, is relatively rigid-adjacent'themiddle of the' embossments.

(See Fig. 7.) Furthermore, the corrugated' platelmay be so formed that the'length of the center line I,
