Y Application iled February 6,1920. .Serial No. 356,693.

To all whom t may concern.'

Be it known that I, SAMUEL H. CONWELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gondola-Car End Walls, of which the following is a specification.

My invention relates to the construction of railway cars, lmore particularly gondolak cars, and has for a primary object to provide a reinforced sheet metal panel for the end wall of a railway car of this type together with novel means for rigidifying the marginal portions ofthe panel and to provide means. for securely attaching the panel to the sidewall structure and underframing of the car whereby the end wall of the car will be rigidified to, effectively resist the various thrusts and pressures to which car end structures are subjected.

A'further and more specific object of the I invention is to provide a novel top chord` construction for a sheet metal gondola car which will be very strong and rigid vso as to be capable of withstanding the rough usage to which this part of the car is subjected, and which, moreover, will give reinforcement to the entire'superstructure ofthe car.

The invention consists in the new and limproved constructions,v arrangementsl and such other incidental objectsas will appear,

from the following description of my invention.

My invention is illustrated in certain preferred embodiments in the accompanying drawings, wherein ,Fig l is a vertical section through one end of a railway car of the gondola type,

illustrating an end construction made in accordance with my invention.

AReferring irst` to Figs. 1 to 4 inclusive of the drzuvings-fl have shown and will devscribe my invention in connection with a gondola car construction though ity willv be obvious that certain of the. features embodied in this invention might be readily used in connection with boX cars. I, therefore, do not wish, to limit the invention to the speciicuse shown or to the structural feature described except in so far as specic -limitations may appear in the appended claims. l

The end structure shown in Figs. 1 to 4 inclusive consists preferably of an end panel made up of two. sheets designated 10 and 1l respectivelyformed with a plurality of horizontally disposed corrugations 12-13 which extend uninterruptedly across the car from side `to side thereof and terminate with the usual ltapered terminals 14, -15 within. the edges of the sheets. VThe sheets are arranged face'to face and secured together by rows of rivets 16` on opposite sides of the corrugations 12-13. The said 95 corrugations 12-13 .are preferably disposed opposite one to another so' as to provide'hollow reinforcing beams whichextend across the car end. The loweredges'of the sheets are bent in opposite directions to 100* provide flanges 17-13 adapted to be secured to the underfraining 19 of the car. The vertical edges of the sheets are bent rearwardly to provide angular attaching flanges 20-21 which overlap the outer and inner surfaces of the side walls 22 and are secured to said side walls by means of bolts 23. The upper edges of the sheet lO-ll are bent in opposite directions to provide a rigidifying chord for the upper margin of the end panel. This rigidifying chord consists preferablyv of webs 24-25 having depending reinforcing flanges 26-27 respectively. The top chord construction is firmly attached to the side wall st-ructure of the car by means of anglar stiffening members or gussets 23"'riveted to the web 24 and web 25 of the vchord member by rivets 29-'30 respectively, overlapping the louter surface of the sidewalls vand secured thereto by means of bolts 31 passing through the side wall boards 22 and bolts 32 passingthrough the side wall boards and falso through the vertical 'attaching flanges 20-21 of the sheets -lO-ll respectively.

In the modification illustrated Fig. 5 the end panel consists of corrugated sheets 33 34 formed along 'their vertical edges with angular attaching flanges 35-36 respectively which overlap the side walls 37 of the car. The' upper edge of the panel is rigidified by means of a top chord Iformed by turning the upper edge of the sheet 33 outwardly to provide a flange 38 and bending the upper edge of the sheet 34 inwardly to provide an oppositely disposed flange When forming a metal sheet with rigidifying corrugations the edges of 'the sheetvv are distorted or drawn inwardly by the pressing operation. This fact is taken advantage of in the chord construction illustrated in Fig. 5 in that the upper edge of the sheet 34 is bent over without removing the irregular portion of the edge.

i :Bv forming the flange 39 in this manner the kflange is increased in width toward the sides of the car. The extremities of the flange 39 are preferably bent downwardly as indicated at 40 and are suitably secured to the vertical flanges 3G by bolts 4l passing through the side walls 37 of the car.

The modification illustrated in Fig. 6

shows an end panel in which the car struc# ture is rigidified adjacent the corner Iposts 42.0f the car. The vertical edges of the inner sheet of this structure are preferably' bent as indicated at 43-44 so as to fit around the inner faces of the corner posts 42, the outer edge being bent rearwardly las indicated Vat 45 and secured to the side ,wall 46 of the car. The outer sheet designatedr47 in this figure may be constructed vsubstantially the same as the outer sheet in ilo-4 inclusive and the 'end `'panel may be secured to the side wall construction of the car by means of the gussets 23 in substantially the same manner as that illustrated in Figs. l to 4 inclusive.

In Fig. 7, I have illustrated another modied form of end construction in which the top chord of the panel is provided by bending the upper edges of the sheets 48 49 in opposite directions as indicated at :iO-51. A channel beam 52 is fitted over the flanges -51 and secured thereto by rivets 53.

In Fig. 8, I have shown a modification in which the end panel is composed of two sheets 54, 55, one fiat and the other corrugated, having oppositely turned flanges 5G, 5T forming the top chord of the end. The sheets are preferably secured together hy rivets on opposite sides of the corrugations 59 of the sheet 55. In Fig. 9 the arrangement is similar except that the top chord formingranges are turned both in the same direction. Sheet 60, the vouter sheet preferably is formed with corrugations and with an out turned flange 6l having a depending rim 62. The inner sheet 63 may be flat and is formed with an out turned vflange 64 secured to flange 6l by rivets 65.
