CAR-WALL STRUCTURE.

App1ication filed May 26, 1919.

To all whom it 'may concern.'

Be it known that I, GEORGE IV. Sninni., a citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Car-Tall Structures, of which the following is a specilication.

My invention relates to a wall construction for railway cars, particularly freight cars, suitable for the sides of the car but more especially for the ends thereof, which latter, because of the tendency of the cargo to shift and of the superstructure of the car to weave, are particularly subject to strains which, if not prevented, shorten the life of the car materially.

My invention has for its object to provide a metal railway car wall structure which will be very light, strong and rigid and may be manufactured and assembled at relatively low cost. The structure, when applied to form the end wall of the car, may be used either on old cars for repair purposes or in the construction of new cars.

The invention is illustrated, in certain preferred embodiments, in the accompanying drawings wherein Fig. l is an end elevation of the superstructure of a railway box car, the end wall of which is constructed in accordance with the invention.

Fig. 2 is a plan view on line 2--2 of Fig. 1.

Fig. 3 is a vertical sectional view on line 33 of Fig. 1.

Fig. 4 is an enlarged vertical sectional View illustrating the formation of one of the reinforcing ribs.

Fig. 5 is a vertical sectional View showing a modified construction, and

Fig. 6 is a similar view illustrating another modification.

Like characters of reference designate like parts in the several figures of the drawings.

The invention is illustrated and will be described as embodied in an end wall structure for a railway boX car, the superstructure of which is otherwise made of wood and of conventional type. 10 designates the end sill of the car, 11 the side sills, 12 the Hoor, 13 the corner posts, 14 the. side sheathing, 15 the side plates, 16 the ridge pole, 17 the roof boards, and 18 the linings of the side walls.

The end structure consists, in the embodiment shown, of four plates 19, 20, 21 and 22,

overlapped and secured together by rivets 23. The plates are formed on their vertical edges with flanges 24 which are secured by bolts 25 to the corner posts 137 the flanges overlapping the side sheathing boards 14. The upper sheet 19 is preferably formed with an inturned flange 26 which takes the place of the end plate and supports the ridge pole 16. Sheets 19, 20 and 21 are formed at their lower edges with channel-like ribs27 which are produced by rolling the plates while hot. The channels are substantially rectangular in cross section but the rolls are so formed that lillets or thickened portions 28, 29, 30, 31 are formed at the corners of the channels. This thickening of the metal at the corners of the ribs gives the ribs additional strength and rigidity. The ribbed portion of each sheet 19, 20, 21 overlaps the upper edge of the adjacent plate, the plates being riveted together on opposite sides of each rib. The lower plate 22 is flat and is secured to the end sill 10 by bolts 32.

In Fig. 5 I have shown a similar construction except that the plates 33 are formed with angular reinforcements 34 at their edges. In the rolling operation the corners are illeted as before to increase the strength of the rib.

In Fig. 6 thev lower edge of the plates 35 are rolled to form bulb angles 36.

I claim:

1. A metal car wall structure formed with integral reinforcing ribs each comprising a web at an angle to the body of the wall having an angularly disposed iiange, portions of which ribs are thicker than the body of the plate.

2. A metal car wall structure formed with integral channel-like reinforcing ribs, poi'- tions of which are thicker than the body of the plate.

3. A metal car wall structure formed with integral reinforcing channel-like ribs generally rectangular in cross section but with fillets at the angles giving increased thickness at these places.

4. A metal car wall structure comprising a rolled plate formed with a reinforcing rib angular in cross section and projecting from the plate, a portionof which rib is thicker than the body of the plate.

5. A metal car wall structure comprising a rolled plate formed with a channel-like reinforcing rib a portion of which is thicker than the body of the plate.

and joined together and provided at their junctions with integral channel-like ribs, portions of which are thicker than the other parts of the plate.

9. A metal car Wall structure consisting of a plurality of rolled plates overlapped and joined together and provided at their junctions with channel-like ribs having fillets at their angles giving increased thickness at these places.

l0. A metal car Wall comprising a plurality of plates the body portions of Which are overlapped and joined together at their edges, one of each pair of overlapping edges having an angular formation integral with the plate, the angle "portion of which is thicker than the body of the plate.

l1. A metal car Wall structureconsisting of a plurality of plates, Which are overlapped at their margins, one plate of each pair of overlapped plates being formed With a rib comprising an outstanding web, the outer portion of Which is 'thicker than the body of the plate.
