Chicago, in the county of Cook and State.

of Illinois, have invented certain new and useiiul Improvements in PressedSteel Car Ends, oi which the following is a s 'ieclfication.

My invention relates to an end structure for railway cars particularly for box cars, and has for its'object to provide an end structure for a railway car con'iposed oi sheet metal and formed with one or more pressed ribs, corrugations or reinforcing members, which extend across the end from one edge to the other so as to constitute truss-like elements trai'ismitting stresses received by theend structure, for example, the thrusts and pressures due to shitting cargoes, to the end frame of the car, and preferably formed also on opposite sides of said truss-like corrugation or corrugations, with a plurality of pressed ribs or corrugations arranged so that they transmit stresses exerted against them to said truss-like corrugation or corrugations and to the end frame of the car; this arrangement of still"- ening and reinforcing ribs'or corrugations resulting in an end structure which is very strong, rigid and durable, and at the same time light in weight and inexpensive to manufacture.

The invention is illustrated, in two preferred' embodiments, in the accompanying drawings, wherein- Figure 1 is an end elevation of the body.

sheet of metal 10 designated in Figs. 1 to 53 inclusive and 11 in Figs. l to 6 inclusive, which is secured, in each case, to the end. frame of the car in any suitable manner. For example, I have shown the sheet in each construction as formed with angular flanges 12 overlapping the corner posts 13 of the car and secured thereto by bolts 14:, the upper edge of the sheet being secured to the end plate 15 by bolts 16 and the lower edge being formed with an iuturned flange 17 intervening between the flooring 18 and the end sills l9 and secured to the latter by through bolts 20. In the construction shown in Figs. 1 to 3 inclusive, the sheet 10 is formed with two sets of vertical corrugations 21 andQZ, preferably pressed inwardly from the plane of the sheet and between the same and running transversely thereto, a truss-like corrugation :23 which is preferably pressed outwardly and is preferably widest and deepest at the center andtap ered down toward its extremities. The trussliho corrugation 223 is preferably arranged in the same plane with the side girths 2 L of the car so that it will transmit the stresses which it receives to said side girths. In order to obtain the full benefit of this arrai'igemei'it, angle irons 27 may be riveted to the end sheet at the extremities ot' the cor-- rugation and attached to the side girths 24; by through bolts 26 (Fig. 3').

If the car be constructed with two side girths on each side in atead of one, the construction of the endmay, if desired, be modified. accordingly so that there will be two horizontal truss-like corrugations 23 instead of one, and three sets of vertical corrugations. Such construction is shown in Figs. 4: to 6 inclusive. In this construction the horizontal or truss-like corrugations-.27, in stead of being formed in the sheet 11, are pressed out of separate bands or girth members 28. The sheet ll is formed with three sets of vertical corrugations 2!) and between or other suitable means.

The heaviest thrusts and pressures against the end of a freight car are causedby the shifting of heavy articles of the cargo such as rails, pipe, and the like, which are placed close down to the floor. with the end provided with vertical corrugations terminating near the lower ed e of the sheet so as to leave a flat marginfor attachment to the frame of the car there is danger that impacts against the'lower portion of .the sheet will stretcher broiiig the inarginailf portion of the sheet so as remake the end of the car leaky. In the constructions shown the inturned flange 17 of the lower sheet prevents this the flange not only serving as a c0nvenient means for attaching the end structure to the sill with a joint which will be grain proof, but also reinforcing the sheet at the place where, for the reasons above stated, reinforcement is particularly necessary.

While I have described my invention in certain .preferred embodiments, some modification in the form, construction and arrangement of the parts as shown and described might be made without departure from the principle of the invention. Therefore I do not wish to be understood as lin1iting the invention to the particular con'strmztions, arrangements and devices herein shown except so far as certain of the claims herein are so limited by their express language.

I claim:

1. The combination with the end frame of a railway car, of a sheet metal end for the .car comprising a sin le sheet of metal extending from top to ottom and from side to side of the car, formed with two sets of corrugations and provided with a separate reinforcing band extending across said end sheet between said sets of corrugations, said band overlapping the outer side of said frame.

2. The combination with the end frame of a railway car, of a sheet metal end for the car comprising a single sheet of metal extending from top to bottom and from side to side of the car, formed with two sets of corrugations and provided with a separate reinforcing band extending across said end sheet between said sets of corrugations and provided with a longitudinally disposed corrugation, said band overlapping the outer side of said frame.

8. The combination with the end frame of a railway car, of a sheet metal end for the car comprising a single sheet of metal extending from top to bottom and from side to side of the car, formed with two sets of corrugations and provided with a separate reinforcing band extending across said end sheet between said sets of corrugations and provided with a longitudinally disposed corrugation which is largest at the middle and tapers toward its ends, said band overlapping the outer side of said frame.
