which may be formed or pressed in the sheet Fig. 5, a sectional view taken on line or sheets of metal of which the car is comof Fig. 4; and posed, whereby the said wall, while being Fig. 6, a sectional view taken on. line -6 light and inexpensive to make, will be car. of Fig. 4. pable of withstanding the heavy strains and Like characters of reference designate pressures to which the wall of a railway like parts in the several figures of the drawcar is subjected when in service and whereings. 8'0

To all whom it may concern:

Be it known that I, \VALTER P. MURPHY, a citizen of the United States, and a resident of New York city, in the county of by suchstrains and pressures are transmitted to the framework of the car and distributed as between the vertical and horizontal members thereof;

Additionally, the invention has for an object to provide a sheet metal wall structure for cars with one or more truss-like elements which extend across it, preferably either vertically or horizontally or in both of those directions, and which are wider at their centers than at their ends, or are equivalently constructed, so that they give a maximum amount of strength and stiffness to the sheet or sheets at the place where The nvention has for further objects such other new and improved constructions,

I arrangements and devices in sheet metal car walls as will be hereinafter described and The w a strength is most needed, to-wit, at the cenbers of the car, the corner posts, and in 9 ter of the structure; the invention in this part to the end sill and end plate of the respect, when used inthe end wall of a. car, and to an intermediate horizontally discar, taking advantage of the fact that unposed truss member which extends across derthe requirements of the-Interstate Com the car from corner post to corner post-and merce Commission there need not be as forms, in effect, a partof the framing. of me much clearance between the ends of two the car or a reinforcement therefor and for railway cars near the. center line of the the sheet metal end wall. In these figures cars as at the sides of the cars where the the upper sheet designated 30 is formed end ladders are placed. with a pressed out rib or corrugation 31 A further'ob ect of the invention is to which extends diagonally across the. sheet provide a our well which, besides .heing more and is deeper and wider at the middle than durable than the ordinary wooden structure, at the ends and with a plurality of shorter will stiffen and reinforce the entire car body diagonal corrugations these corrugations as against weaving and other like being is crab-iv ti, or substantially tending to distort and strain the same. mathematical para} lelism being unessential, the purpose of the corrugations being to ,actas beams to 'distribute the stresses on the endstructure to the vertical and horizontal, members of the car framing. The lower sheet 33 is formed. with similar corrugations 31?, 32, which preferably extendacross the sheet in the opposite direction from the corrugations of f the uppersheet. The upper margin of the 10 posed flanges 36 to overlap the corner posts 27' 'and which .may be secured thereto by means of bolts '37. The lower sheet 33 may l slmilar manner, may overlap the corner posts 27 and be secured thereto. The lower sheet may also have an inturned-fiange 39 intervening between the end sill 28.and the 7 trated in Figs. 4 to 6 inclusive, wherein thehave similar side flanges 38 which, in a flooririg29 and secured thereto by bolts 40.- A modified form of the invention is illusendbwall consists of-two upper sheets 41 and 42 formed on their'meeting edges with outstanding flanges 43 and on their lower 0 edges with outstanding flanges 44 and apa'ir v of - lower sheets 45 and 46 formed with margins-of the lower sheets being flat and 1 upper sheets by means of rivets 48.' The the end structure, which is naturally subtoward their outer extremities. The flanges the joint between the sheetsabsolutely waterproof. The flanges 47 of the lower sheets bottom." Thiscon'struction provides an increased reinforcement for the lower part of jected to the greateststress and pressures;

The flanges. 44 are preferably secured to the flanges 47 by meansof angular gussets 51'.- These gussets serve to combine the flanges 44, into a .stiflf unitary truss, equivalent in" function to the truss member or. flange 35. 55'

In" this modification each sheet is formed with an X corrugation 52,.and preferably with vertical corrugations 53 and horizontal I corrugations 54. The function of the X corrugation is to transmit stresses on the center portion of the sheet to its corners, that is to vsay, to the framework of the car andthe horizontal and vertical truss members. The horizontal and vertical corrugations stlfl'en and'reinforce the sheets asagainst local thrusts. Ineachof the embodiments of the 'ber ofreinforcin .be increased or dnninished in either of the illustrated forms, and these members "might The upper sheet may be formed with angularly dis-' extending back of the lower edges of the g, upper sheets where they are'secured to the g toward'its endsare shown "as increasing in width toward 'the invention disclosed, trusses orrein-forcing members are provided which 'serveparticularly to re nforce the center'p'ort-lonpf the structure where reinforcement is most re- 1 quired. In each instance advantage is taken of the fact. that, yvhen' utilizing the; struc ture in the end wall,;the center" arts of the end of the car may projeetout urther'than the side portions to which the end ladders are aifixed. It is to be noted that-the numor truss members might be'constituted-by separate: elements where.

they are shown as provided. by the Hanging of the sheets. Obviously, also, the number a of sheets, which in one case is four and in the other two," mayf-be 'variedas circumstances require, depending on the type of car to which the end is applied; v Where the 'car is provided, as herein shown, with reinforcin or truss members runnin "in difl'erent dlrections, and each secure to or integral with the middle of the'sheet metal structure, thej wall of the-car is not only stiff and strong in itself, so as to be capable of withstanding cargo thrusts, j i

but it also serves to reinforce and strengthen the framingof the-car as against-weavingstrains.

referred embodiments of the invention, but it is obvious that one skilled 'in the art might make modifications thereof without departingfrom the.spirit of the invention;
