construction, lwhich sha1-'l be very strong and` frigid, which can be cheaply made and 'easily attached either to a Vnew car or to an `old car to replace the ordinary wooden end, and

which shall have certain other novel and- 'improved features to be hereinafter' described and claimed. v A A The invention is illustrated, in certain preferredembodiments, in the accompany ing drawings, wherein- Figure l is an end elevation of a railway box car showing one form ofour invention, Fig. 2, a sectional view taken- 0n line 2-2 of Fig. l, looking in the direction ofntheA arrows; Fig. 3, 'a sectional plan taken on line 343 of Fig. 1; Fig. 4, 4a view, in perspective, of the girth member used for se curing the upper.V and lower sheets of the end; Fig. 5, a view similar to Fig. l illustrating a modified construction; FigfG, a sectional view taken on line 6-6 of Fig. 5 Fig. 7, a fragmentary end elevation of a car illustrating another modification, and Fig. 8,-a detail sectiontalren on line 8-8 of Fig. 7, looking in the direction of the arrows.

Like characters of reference lindicate like parts in the several figures of the drawings. Referring first to Figs. l to4 inclusive, 25 designates the corner posts ofa box car of standard construction, 26 the endsill, 27 the end plate," 28 the ridge -pole,29 thepurlins, and 30 the side sheathing ofthe car. The sheet metal end is composed preferably of two ormore sheets of metal which are secured to .the car .and are lfastened' on'ept another by means which provides a Awater- Specification of Letters Patent.

proof joint. In the construction shown in these-figures there are two sheets, an upper sheet 31 and a lower sheet 32, which. are secured together by ineans of what we have termed a girth member 33. Both sheets have flanges .34 on their vertical edges which are secured to the car preferably by means of the bolts 35 passing through the corner posts 25. Bolts 36 secure the uppersheet to the end plate 27. The same bolts may be used for the attachment to the car` .of a fascia plate 37. t The lower plate has an inturned flange 38 which is secured to the end sill 26 by the bolts 39. The'sheets are preferably formed with lribs or corrugations.V ln

the 'construction shown in the rs't four tig` ures the corrugations or ribs 40 are disposed horizontally' and extend substantially from side to side of the end, that is, from one .corner post across to the other so that the end is reinforced uniformly throughout substantially the entire portion between the corner posts. The girth member is provided with the angular anges 44l 'bolted to the `framework of the car' and .is preferably formed with the outstanding rib or corrugation.. 42. rlhe edges of the sheets 3l and 32 are riveted to the rims or flanges 43 above and below therib 42. The latter' serves `to prevent water from entering the joint between tlie girth'member and the lower sheet 32. i It also givesstrength and rigidity to the girth member and-to the end structure` as a whole. In, order to increase the capacity ofthe car and .to add strength and rigidity to the endrstructure, which is designed to be made of comparatively thin vsheet metal, the end structure is made so that it bows or bulges outwardly, this conveXi-ty being preferably substantially uniform from ltop to bottom of the car. If the sheets were, bent or otherwisevformed so that their cross section .described an arc of projecting rib unless the body of the car were shortened.

a circle therefwould be diiiiculty in provid- I. Ving the `car with an Yend ladder and in employing'the girth member with its outwardly' An orgler of the Interstate Commerce shall extend to within twelve inches of a vertical plane parallel with the end of the car and passing through the inside face of thev coupler knuckle. If the curvature of the end were ,struck on the arc of. a circle the inner corners of the end ladder grab irons 44 would necessarily stand farther out than the other corners. This would necessarily mean that the body of the car as a whole would have to be proportionately shortened in order to comply with the requirements of the Interstate Commerce Commission. The use of the girth member with its'projecting ribwould involve the same diiiiculty. To overcome this thesheets are depressed at each si'de of. the vertical center line. In other words the-cross section of each half of a sheet, considered as divided by the center -line of the plate, describes a reversed curve.

This adds rather than takes away from the strength and rigidity of the structure and diminishes the capacity of the car very little. The inner corners of the ladder grab irons are by thismeans thrown in so that they project but little, if any, beyond the outer corners.

. We do not claim herein a reinforcing girth member for connecting the upper and lower end sheets of a steel end and reinforcing the same, as this is the invention of Vinton E.

-Sisson and is claimed in the application of said Sisson led December 11, 1911, Serial No. 665,098. v In Figs. 5 and 6 we have shown a similar constructionto that shown in Fi s. 1 tojinclusive except that there is a di erent dis-v position of the corrugations. While itis feasible to form the sheets with corrugationswhich extend across the sheet from one si'de to the other', as shown in Fig. 1, the Vpressing of a sheet of this sort, if the corrugations are of any considerable depth, is likely to be dif- `ficult owing tothe tendency of the metal to draw and distort the sheet.

To overcome this diiculty the sheets 45 and 46 are formed withl a series of centrally'arranged corrugations 47 which are preferably widest at their middle points and tapered down toward the ends and which preferably do not extend very close to the edges of the sheet. At each side of the sheet between these corrugations is a series of preferably similarly tapered corrugations 48 which extend close to the edges of the sheet and between the ends of corrugations 47. By this arrangement the stamping of the sheet is facilitated. At the same time .the entire part of the end within the framework ofv the car is given a reinforcement which is [substantially uni- A diiferent Loevnse forni throughout,no part being weaker than t Mmm disposition of the corrugation any other.

by means of whichthe ends of each corrugation are out of vertical alinement with Vthe below it, is shown in Fig. 7, the corrugations:

lends of the corrugation directlyl above and 1 being designated 49. This staggered arrangementfacilitates the pressing of the sheet by preventing the metal from drawing in much the same way as the arrangement shown in the preceding two figures.

Inthe construction shown in Figs. 7 and 8 the upper sheet 50 is formed with a fiange 51 having a downwardly projecting li 52. The lower sheet 53 is formed with a ange 54 vwhich is riveted to the ange 51. This provides fora waterproof joint between the sheets.

While we have shown oui' invention embodied in certain preferred constructions, it will be. obvious that other modications might be made without departure from vthe invention. Therefore we do not limit ourselves to the particulars shown and described except as the same are made specific limitations in certain of the claims; the purpose v being to cla-im, both broadly and narrowly,

whatever patentable novelty our inventionl may possess in view of the state of the art.
