END STRUCTURE FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Nov. 28,1916.

To all'whom it may concern:

Be it known that I, PERCIVAL H. TRUMAN, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in End Structures for Railway-Cars, of which the following is a specification. My invention relates to sheet steel end structures for railway cars particularly suitable for box freight cars. The regulations of the Interstate Commerce Commission require certain clearance between the portions of the ends of a box car. where the end ladders are placed, the object being to insure the safety of trainmen using the ladders. This re uirement does not apply to the center portion of the end of the car which may be made to bulge or project beyond the portions at the sides of the car.

The primary object of my invention is to provide a car end structure which takes advantage of the fact that the center portion or the end my project out beyond the side portions and utilizes this space. at the center of the car for giving added strength and rigidity to the end structure without diminishing the loading capacity of the car.

The invention has for further objects such other new and improved constructions, arrangements and devices in sheet metal car ends as will be hereinafter described and claimed.

The invention is illustrated, in certain preferred embodiments, inthe accompanym drawings, whereinigure 1 shows, in elevation, a sheet metal carend, of one type, constructed in accordance w1th my invention. Fig. 2 1s a vertical sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional plan on line 33 of Fig.

1. Fig. 4 is a view, in perspective, of one of the intermediate elements or panels making up the end structure. Fig. 5 is a fragmentary sectional view illustrating a modification. Fig. 6 is an elevation of another form of the invention. Figs. 7 and 8, sectional views taken on lines 7--7 and 88 respectively, of Fig. 7; Fig. 9, a view in ective of one of the panels making up lid gnd shown in the preceding three figurea; Fi 10, a sectional view similar to Fig. 8 owing a modification; Fig. 11, a view, "in perspective, of one of the panels employed in the modified construction 29; the

shown in Fig. 1O; Fig. 12, an elevation of another embodiment of the invention; Figs. 13 and 14, sectional views taken on lines 13- -13 and 1414, respectively; of Fig. 12.

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

The end structure shown in Figs. 1 to 4 inclusive is made up preferably of an upper panel 25 securedto the end plate 26 of the car, a lower-panel 27 secured to. the end sill 28 and a plurality of intermediate panels lower edges of the panels 25 and 29 being offset as shown at 30- and overlapping the panels respectively below them. Each of the several panels is formed with angularly disposed lateral flanges 31 secured in any sultable manner to the corner posts 32 of the car. Each panel is formed with an inturned corrugation 33 which preferably deepens toward the center of the panel-so that it provides a truss-like member extendmg across the concavity of the panel. Preferably the corrugations are pressed in to substantially the plane of the outer faces of the corner posts. That is, the depth of the corrugations at the vertical section is substantially equal to thebulge of the panel at that point. This gives a maximum reinforcement without the waste of any space within the end framing of the car. The structure may be further reinforced by forming the panels 29, and also if desired, the lower panel 27, with inturned flanges 34 on their upper edges which serve the same function as the corrugations 33 forming truss or tie members resisting the deflection of the panels under stress of cargo thrusts. The number of panels constituting the end might be increased or decreased as might be found expedient.

In Fig. 5 the panels 27*, 30 are formed with flanges 34 but are not corrugated.

In the construction shown in Figs. 6 to 9 inclusive, the end consists of four triangular panels 44, 45, 46, 47 preferably formed with corrugations 48 and at their meeting edges with outstanding flanges 49 secured together by rivets 50,-the flanges being widest-at the center oint of the end and tapering down to noth 'ng at the corners. The panels 44, 46 are formed with angular flanges 51 for attachment to the corner posts 32. The upper panel 47 has a flat margin 52 in the plane the end plate 26. The corresponding marginal portion 54 of panel 45 is preferably bent inwardly and secured to the upper surface of the end sill 28 by bolts 55.

Figs. 10 and 11 sliow a modificatmn of the construction just described. The panels designated 44, 45 46 and 4-7 are formed so that they are inclined toward the center point of the end, that is, toward the apex of the triangle in each case, and are providedwith inturned flanges 49 at their meeting edges. In other respects the construction may be exactly the same as that shown in Figs. 6 to 9 inclusive.

The construction shown in Figs. 12 to 14 inclusive consists preferably of an upper sheet 65 and a lower sheet 66 formed with convex portions 67 68 and united by a line .of rivets 69. The center portion of the end which is of spherical curvature, is reinforced by providing the lower sheet 66 with an inturned flange 70.

I claim:

1, An end structure for railway cars comprising a plurality of rectangular metal end sheets secured together, formed at their meeting edges with inturned angular flanges,

and disposed so that the structure projectsout farther at its vertical center line than at the sides.

2. An end structure for rallway cars comprising a plurality of metal end sheets secured together, disposed so that they bulge out at the center and formed with interior flanges constituting trusses across the bulged portion of the end.

3. An end structure for railway cars comprising a plurality of metal end sheets secured together, disposed so that said struc-' ture bulges out at the center and formed at their meeting edges with inturned flanges.

4. A11 end structure for railway cars comprising a plurality of corrugated metal end sheets secured together, formed at their meeting edges with'inturned angular flanges, and disposed so that the structure projects out farther at its vertical center line than at the sides.

5. An end structure for railway cars com-' prising a plurality of corrugated metal end sheets secured together, disposed so that they bulge out at the center and formed with interior flanges constituting trusses across the bulged portion of the end.

6. An end structure for railway cars com- Ooples of tliis patent may be obtained for mg across the car from side to side with the edges of adjacent panels overlapping and formed with inturned flanges.

9. An end structure for railway cars com prising a plurality of bowed panels extending across the car from side to side with the edges of adjacent panels overlapping and formed with inturned flanges and within wardly pressed horizontal corrugations.

10. The combination with the end' framing of a railway car, of a sheet metal end structure which is bulged outwardly from' said end framing and formed with reinforcing corrugations which extend from one corner post to the other and throughout their length are pressed inwardly to substantially the plane of the outer surface of thee 11d framing of the car.

11. The combination with the end framing of a railway car, of a sheet metal end structure which .is bulged outwardly said end framing witha substantially imicorrugations which extend from one corner form curvature from top to bottom of the end and formed with horizontal reinforcing post tothe other and throughout their length i g i are pressed inwardly to substantially the plane of the outer surface of the end framing of the car.

12. A sheet metal end structure for railway cars which is convex and formed with one or more inturned corrugatlons, the depth of which at any section taken across the 1 same is substantially the'same as the amount of convexity of the end structure at that Witnesses: I
