.whichj'struc tures of SHEET-METAL END STRUCTURE wF 32 To all whom it may concern lie it known that I, WALTER P. MURPHY, 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 Sheet-Metal End Structures for Railway-Gars, of which the,

following is a specification.

My-invention relates to metal end structuresfor railway cars, and has as its object the provision of certain improvements in sheet metal structures for railway cars that will not be subject to the present diiliculties in manufacturing sheet metal end structures and one in which the durability and strength for resisting the various stresses to the aleove character are subjected will be increased.

More specifically, it is the object of the invention to provide a corrugated end structurethat will presentcertain economic advantages of manufacture over the types of against the car it necessary, to fit the car ,are pressed, while in the latter case corrugated end structures in which the ends of the corrugations terminate within the edges of the end sheets and also have structural features which will increase its strength ,for resistance against the thrusts of the cargo end, caused by the sudden of the car. The metal starting or stopping which the (201'- end structures referred to, in rugations terminate short of sheet, while being practical, are more expensive to manufacture than the structure in which the corrugations extend to the end of the sheet, as they require expensive dies between which the sheets,'after being heated,

the corrugated sheets may be formed by the well known rolling process in which the cold metal may be formed into sheets of one or more stock sizes and afterward sheared oil, towhich it is in-. tended to lee-applied. e 4

A 'further object of the invention is to provide means for securing the end sheets together and to the car frame that Wlll rigid ity the frame and will provide water-proof "joints between the end sheet and the car frame.

The invention has as further objects the arrangement, construction and combination .of'f parts hereinafter niore specifically de- WALTER 3P. HUB/EEK, 033 CHICAGG, ILLHIDIS.

girth ineniber ii i of theend plate same and is provided with a corrugation or rib 36. The corrugation or rib36 of the reinforcing or girth member is shown as being deepest at the center, as at 37, and tapering down and terminating short "of the end so as to provide a comparatively wide attaching flange 38 which is secured to theside plate means of bolts ed. mom or or girth 35 is provided with flanges The reinforcing 41' and 42, the former of which extends up 4:3 so as to prevent under the fascia plate between the flange water from working in and Wooden end plate, said Wooden-end plate by nieans oi bolts 44:. The lower flange is formed with corrugations as whioh fit over the corrugations 27 at the upper edge of the sheet 25, the sheet being secured thereto by rivets 46. The girth member when attached to the ear in this manner strengthens the wooden end plate securely binds the side plate and. also more In tact,

I60 1 having 55 extending transversely of the corrugaend sheets fronrside to side of" and ,Qfthe flooring. 57 and t if made heavy enough it could take the place of the end plate, making a wooden plate unnecessary. The sheets 25 and 26 may be secured together in any suitable manner, for example, by the lap joint 47 in which the upper sheet overlaps the lower sheet and forms a stiffening strip across the end. To further strengthen the end at the point of j'ointure of the sheets I preferably provide a girth member 48 which is provided with a corrugation 49 similar to the one shown on the reinforcing-member or top girth 35. Both of the flanges 50, 51 of the girth 48 are corrugated so as to fit into the corrugations 27 of the upper sheet 25, the angular flanges 52, extending around the corner of the car, are secured thereto .by the bolts 32 which extend through both flanges 29, 30 of the end sheetsfandthrough the corner post. At the lower edge of the car end I preferably provide another transverse reinforcing member or' girth 53 provided with angular flanges 54 secured to the corner post and with a strengthening rib 55. The lower web 56 of the strengthening rib preferably extends between the flooring 57 and the end sill 58 and is secured to the latter by bolts 59. The upper web 60 of the rib 55 is formed'with a flange 61 which is provided with corrugations adapted to fit over the corrugations 28 of the lower end sheet 26 and is secured thereto by rivets 62 which are spaced close enough together to provide a water-tight joint. The lower edge of the end sheet 26 preferably extends down below the upper edge forward edge of the floor plank 57 is formed with rounded portions 63 which fit into. the concavities formed by the corrugations 28 so as to prevent any portion of the cargo, when it is composed of grain or the like, from entering the corrugation 55 and thereby causing difliculty to remove 'it. The corrugations or ribs 36, 49 and 55 of the girth members preferably extend transversely of the corrugations in the end sheetgm While the corrugations alone may be stij' ng enough to withstand the ordinary thrusts of any heavy cargo such as T-rails, lumber or the like, against the car, caused by the sudden startingor stopping of the car, the car end is often subjected to unusually hard shocks due tothe tions of the universal practiceof trainmen in making u the tra ns. n the railway yards, in which the car is either run down an inclined track or given a start by the locomotive and then released therefrom and permitted toibump into the cars, previously sw1tched or placed on t e branch track on which the particular train is being made up. It will be seen that by the stifiening corrugations 36, 49 and i a the car andby'havin the end sheets secured directly to one of t eir flanges, the girth members-will receive a portion of any shock that may occur at any particular point of the sheet, that is, the corrugation or rib 55 would receive the shock when it occurred at the lower part of the car and would divide the stresses between the two corner posts and end sill.

end sheet 25 secured to the flange 42 of the By having the upper edge of the A girth 35 the same results are obtained when the thrust occurs near the top of the car, as in cases when the car is loaded with lumber.

In Figs. 7 and 8 of the drawing, I have illustrated modified forms of transverse reinforcing or girth members 35, 48 and 53.

In the modified forms the corrugations 35",

48 and 53 extend around the corner of the car and terminate ashort distance Within the end of the attaching flange, shown best I I in Fig. 8. This structure strengthens the corner of the car and by having the corrugations terminating as shown prevents the rain and dirt from being driven into the corrugations, which would corrode and weaken the -members in which these are pressed.

While I have illustrated my invention in certain preferred embodiments, it will be understoo that further modifications might be made, within the scope of the claims herein, without departure from the spirit of .the invention.
