Unite States Patent f fiice ROOF STRUCTURE FOR RAILWAY CARS John W. Allen, La Grange, Ill., assignor to Stanray Corporation, a corporation of Delaware Continuation of application Ser. No. 613,216, Oct. 1, 1956629 This application Aug. 14, 1959, Ser. No. 833,

8 Claims. (Cl. 105-404) This application is a continuation of my copending application, Serial No. 613,216, filed October 1, 1956, new abandoned.

This invention relates to the structure of railway car roofs, particularly at the eaves thereof, and is especially concerned with the meeting margins of the roof sheets and the side sheathing being formed so that they cooperate in a manner to avoid the necessity of the usual side plates for such cars.

It will be obvious, too, that this structure may be advantageously employed in other metallic structures where relatively strong structural conditions are desirable at the eaves area.

The principal object of the invention is to provide roof and side portions of an enclosure wherein the meeting margins are integrally formed so that one cooperates with the other to provide a hollow box section at the eaves of ample strength so that the usual side plate provided for cars or other metallic structures may be eliminated at great savings in weight, amount of welding, and riveting.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawings, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a top plan view of a railway car roof embodying my improved design.

Figure 2 is a side elevation of Figure 1.

Figure 3 is an enlarged sectional view on the line 3-3 of Figure 1.

Figures 4 and 5 are views similar to Figure 3 but of modified forms of the invention.

Figure 6 is a view of another modified form of the invention.

In the drawings, which illustrate the invention as applied to a railway car roof, the car roof sheets are shown as extending from caves to caves of the roof and arched to provide a ridge portion tranversely at the center of each sheet, so that, when all sheets are applied, the ridge portions aline and form a continuous ridge extending longitudinally along the center of the roof from end to end of the car.

Each of the intermediate sheets 10 are provided with a pair of upwardly pressed embossments 11 which extend from substantially end to end of the roof sheet. The end roof sheets 12, however, are each provided with but one embossment 13, similar in all respects to the embossments 11. The end roof sheets have but one embossment each, so that the Width of said end sheets may be varied to provide a composite car roof of a certain length. Running board saddles 14, of any desired form are attached to said embossments to support the running board 15 at the proper height above the roof.

The invention is particularly concerned with conditions at the caves of the car, and in Figure 3 it will be noted that the end margin of the roof sheet extends over the upper edge of the side sheathing 16 a short distance as at 17, and is then turned downwardly as at 18, and

edge welded thereto as at 20. The upper edge of the sheathing 16 extends to the roof sheet 10 and is edge welded thereto as at 21 so that the channel-like formation 171819 of the outerma'rgin of the roof sheets and the included portion of the upper margin of the side sheathing 16 form a hollow box section, adding greatly to the strength of the eaves portion of the roof, eliminating the necessity for the rolled metal side plate section ordinarily employed in such structures.

The car underframe, not shown, is of ordinary construction and is provided with a side sill which supports the lower end of a plurality of spaced side posts, the upper end of one of which is indicated at 22. These posts extend vertically, and each comprises a channel section having laterally extending flanges which are Welded to the outer surface of the sheathing 16. The posts extend upward to and are secured to the flange 19 and are included within the bounding vertical planes of said flange.

In Figure 4, the same result is obtained but by a different means. In this view the roof sheet is shown at 39 which extends to the vertical plane of the side sheathing 31, and is turned downwardly in said plane as at 32. The side sheathing extends upwardly to the lower edge of the portion 32'of the roof sheets, is then turned outwardly a short distance as at 33, thence upwardly as at 34 parallel with portion 32, and thence inwardly as at 35 in the plane of and to the roof sheet 30 to which it is edge welded as at 36. Thus the channel-like formation 333435 integrally formed with the side sheathing 31, together with the included portion 32 of the roof sheet 39, form a hollow box section similar in effect to that shown in Figure 3.

In Figure 5 a further modification of the invention is shown wherein the roof sheet 40 extends over the upper edge of the side sheet 41 and is then turned downwardly and outwardly as at 42 and thence inwardly as at 43 to the side sheathing 41 to which it is welded as at 44. The upper edge of the side sheathing 41 is welded as at 45 to the roof sheet 40. With this formation of the outer margin of the roof sheet, the portions 42 and 43, together with the included portion of the upper margin of the side sheathing 41, form a triangular box section which has suflicient strength at the eaves to replace the usual rolled metal side plate used in such structures. One slight advantage of a triangular box section over the rectangular forms of the other two views is that a triangular section. cannot collapse without at least one of its sides failing.

In Figure 6 another modification of the invention is shown wherein the side sheathing 51 is turned laterally inwardly as at 52 and then upwardly as at 53 to the under side of the roof sheet 54 and to which it is welded as at 55. The roof sheets 54 extend over the upper edge of vertical portion '53 to the plane of the outer sheathing 51 and are then turned downwardly forming a flange 56 which overlaps the side sheathing 51 somewhat and' welded together as shown, they form a hollow box section at the eaves providing the required strength at that area of the roof and side.
