To all whom t may concern.'

Be it known that I, IRA S. DowNrNG, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sheet-Metal Car Ends, of which the following is a speciication.

My invention relates to the construction of railway cars, particularly boX cars, and has for its primary object to provlde a sheet metal end structure for railway cars which will be strong, rigid, durable, and readily attached either to a new car or to an old car to replace a broken or worn end.

The invention has in View, particularly, a sheet metal car end constructed or provided with reinforcing elements or ribs, as they` mayl be generically termed, so disposed that the structure will withstand the peculiar shocks, stresses and pressures exerted against the end of a railway car.

By constructing a car end in accordance with my invention, in the manner to be hereinafter described, it will be at the same time light and very strong and durable.

The invention is shown, in a preferred embodiment, in the accompanying drawing, whereinl I Figure 1 is a view in elevation of the end of a railway box car omitting the trucks and certain other parts which are not essential to the understanding of the invention; Fig. 2, a fragmentary sectie-nal p lan taken ou line 2 2 of F ig. 1; and lll ig. 3, a detail sectional view on line 3-3 of Fig. 1.

Like characters of reference designate like parts in the several figures of the drawln the drawings, 10 designates the corner posts at one end of the car, 11 the end sill, 12 the outer side sheathing, 13 the inner sheathing, 14 the ridge pole, 15 the purlins, 16 'the roof sheets, and 17 the usual end fascia plate.

Referring first to Figs. 1 to 3 inclusive, the end structure is composed of a plurality of metal end sheets, preferably three in number, which extend from top to bottom of the car and are designated 18, 19 and 20, respectively. r1`he outer sheets 18 and 2() are formed on their outer longitudinal edges with angular flanges 2l secured to the cor- 11er posts 10 by any suitable means, for eX- `sheets are provided on their lower e The upper ends of ample, the i lag screws 22. Preferably the das wlth lnturned flanges 23 which are bolted to the end sill ll. The-sheets are formed on their meeting Vertical edges with flanges 30 which are riveted one -to another as shown.

The sheets are preferably formed with pressed ribs or corrugations 29 which are disposed horizontally. With this arrangement any local thrust on the car end, for example the impact which some relatively small, heavy, movable article forming part of the cargo may give against the endwhen the car is suddenlv stopped or started, is

taken up by the eorrugations and the punci turing or breaking of the end thereby prevented. The thrusts on the horizontal ribs are transmitted to the stiff, vertical ribs formed by flanges 30 which, it will be seen, run from the top to the bottom of the car and are relatively strong and rigid. rllhese vertical ribs serve, in effect, as reinforcing posts intervening between the corner posts of the car, strengthening and rigidifying the end structure and also carrying some of the roof load.

Preferably the end sillV 1l projects out beyond the end sheets and the vertical ribs or posts formed by the angular flanges on the meeting edges of the sheets are secured to the end sill by angular plates 31. In the construction shown the car has the ordinary end plate, designated 32, to which the upper edges of the sheets are secured by bolts 33. the flanges 30 are capped by cap` pieces 3% secured to the end plate by bolts 33 and 35. The fascia plate 17 is notched so that it fits over the cap pieces. Preferably rivets 36 extend through the cap pieces and flanges. The cap pieces, in addition to securely attaching the flanges to the end plate of the car, waterproof the end structure at these points.

While I have described my invention in a preferred embodiment, it will be understood that further modifications might be made without departure from the invention.

l claim:

1. The combination with the framing" of a railway car, of a sheet metal end structure comprising a plurality of end sheets extending from top-to bottom of the ear and provided along their meeting edges with angular flanges which are secured together,

and means for engaging vthe flanges with the frame members. at the top and bottom of the car which provides waterproofing for the upper ends of the flanges.

2. The combination with the framing of a railway car, of a sheet metal end structure comprising a plurality of end sheets extending from top to bottom of the car, formed with pressed ribs and provided along their meeting edges with angular flanges which are secured together, and means for engaging the flanges with the frame members at the top and bottom of the car which provides waterproofing for the upper ends of the flanges.

3. The` combination with the framing of a railway car, of a sheet metal end structure extending from top to bottom of thhe car, formed with horizontally disposed pressed ribs and provided along their meeting edges with angular flanges which are secured together, and means for engaging the flanges with the frame members at the top and bottom of the car which provides Waterproofing for the upper ends of the flanges.

4. The combination with the framing of a railway car, of a sheet metal end struc-v ture comprising a plurality of end sheets extending from top to bottom of the car and provided along their meeting edges with angular flanges which are secured together, and means for engaging the flanges with the frame members at the top and bottom of the car so that said pairs of flanges constitute posts intervening lbetween the corner posts of the car, the upper of said engaging means being formed to waterproof the upper ends of said flanges.

5. The combination with the framing of a railway car, of a sheet metal end structure comprising a plurality of end sheets extending from top to bottom of the-.can formed with horizontally disposed pressed ribs, and provided along their meeting edges with angular flanges which are secured together, and means for engaging said flanges with the frame members at the top and ybottom of the car so that said pairs of flanges constitute posts intervening between the corner posts of the car, the upper of said engaging meansbeing formed to waterproof the upper ends of said flanges.

6. The combination with the framing of a railway car, of a sheet metal end structure comprising a plurality of end sheets eX- tending from top to bottom of the car formed with horizontally disposed pressed ribs and provided along their meeting edges with angular flanges which are secured. together, cap pieces over the upper ends of said flanges which are secured to the framing at the top of the car, and angle plates which secure the lower ends of said flanges to the endsill of the car.

7. The combination with the framing ofa railway car, of a sheet metal end structure comprising a plurality of end sheets extending Jfrom top to bottom of the car `and provided along their meeting edges with angular flanges which are secured together, cap pieces over the upper ends of said flanges which are secured to the framing at the top of the car, and angle plates which secure the lower ends of said flanges to the end sill of the car.
