Be. itlcnownt M MexldSoi-rnnums, a citizen of the. United States, residing" at "Chicago, in the county of fCOOl'. and State of llhnoishaye invented cer useful Improvernents in ieeping Ca'r Bunlrs, of which the'following is a specificsln the construction steel sleeping cars one or" the problems to be solved isthe production b KS or berths;oi metal or other non-combustible material in. such a manner and wlth'sucn structural characteristics that they will possess adequate strength and rigidity and willst the same time be of light weight. Sheet-metal is suitable'iorthispur- "21 like reference re parts, 3.

By reference to these drawinps will be apparent that the main body or the bunk is composed of a curved thin sheet-metal plate 10, having a depressed or sunk panel 11, for strengthening purposes and also for pleas ing appearance. At the front or outer edge the metal plate 10, is bent upwardly to pro- Vide the outer strip 12, then inwardly to form the portion 13, then downwardly to form the part id and again inwardly to pro- .vide the small flange 15, which bears against theinner surface of the plate 10 and is spotstanding stiffening and strengthening hel low rib or flange. Along the back edge of the bunk the plate of sheet-metal 10, is similarly bent to provide a hollow rib or flange 16, of substantially greater width than the p ecification of Letters Patent.

At its back corners and-outstanding from its end ribs or flanges 18 the bunk is supplied with pivot or hinge pins, :28, which the bunk or berth may be hung in place in the car and be readily swung to open or closed position. iilso the outer face of the end flanges 18, have fastened thereto in any approved manner any suitable means such as 29 for the attachment of the safety cords which may be of usualand customary construction. 7

By'cofnstructing the bunk infaccordance with thisinvention such for example as is indicated in the particular embodiment shown in the drawings a berth 0r bunk may be provided which will possess great strength reteste li ge, ieio. Application filedDecember 8, 1908. Serial Ho. senses. 1 I

Although I have herein set forth with some degree of particularity one especial embodiment of the invention and have described in detail its various features of construction, I do not wish to have it understood that the invention is limited or restricted to such exact structural characteristics because many minor mechanical changes'may be made in thcberth or bunk herein described and illustrated without departing from the heart and essence of the invention and without sacrificing any of its substantial benefits and advantages.

Although I have above referred to spotwelding as a suitable means for fastening certain parts together, it should be understood that other means for this purpose could be employed although perhaps not quite so advantageously.

I claim:

1. A'railway car bunk made of thin sheetmetal having a marginal hollow flange integral therewith and formed by bending the sheet-metal of the main body of the bunk to suitable form, substantially as described.

2. A railway car bunk made of thin sheet- -1netal having a marginal flange integral therewith said flange having a. portion resting against and welded to theinner side of the bunk, substantially as described.

3. A railway car bunk made; of thin sheetmetal having a hollow mar inal flange integral therewith, said flange being formed by suitably, bending the sheet-metal of the main body and having a portion resting a ainst and welded to the inner surface of th8%)l1l1k, substantially as described.

4. A sheet-metal railway car bunk ha'vin strengthening and stiffening margins flanges and .a depressed panel in the main body of the bunk, substantially as described.

5. A sheet-meta-l railway car bunk having hollow strengthening and stifi'ening marginal flanges integral with the main body of the bunk, the latter having a depressed panel, substantially as described.

6. A railway car bunk made of thin sheetmetal having a hollow marginal flange integral therewith, said flange having a portion resting against and welded tothe inner surface of the bunk, said bunk also having one or more hollow sheet-metal strengthening ribs welded to its inner surface, substantially. as described. 7
