CAR-ROOF.

essaies.

roofs intended primarily for freight cars,v

but it' is applicable to Vother kinds of roofs.

. The objects of the invention are simplicity,

strength, durability, and tightness against leaks. vA further object of the invention is the prevention ofcon'densation of moisture or sweating on the under sides of the roof plates. l

This invention consists in the shape and arrangement of the carlines and roof plates and manner of securing them together.l The invention also consists in arranging a wood lining beneath the roof plates, and in the manner of assembling and retaining the lining in place. Theinvention also consists in .the running board supports and manner of securing them to the roof.

Furt

in connection with the following description of the car roof shown in the accompanying A drawings, and what the invention consists Ain is more particularly dened in the ap pended claims.

In the drawings, in which the same reference characters designate the same parts in the several views,

Figure 1 is a plan view of a portion of a;

the eaves portion of the roof on `the line 2-2 in Fig. 1; and

Fig. 7 is -a longitudinal section throughl the end of the car at the ridge, on the line 7 7 in Fig. 1.

The roof shown in the drawings is applied to a car having Z bar side plates 10 and a pressed metal-end plate 11; but the ii/ivention is applicable to cars having w/ood side and end plates. rThe carlines 12ers of pressed steel, channel shape in crosssecn tion, with the top edges of'their side walls. flanged outward for supporting the roof.

beneath the roof plates. The ends of the carline flangesare bent down and hooked over and riveted to the inner flanges of the side plates. End brackets 16 of pressed steel conforming t the shape of the under side of the carline at its ends are riveted to the side of the carline, and to the inner sides lof the side plates.

The side margins of the' roof plates are lapped over the carliiies, and are secured together and to the carline-langes by two rows of rivets 17. The rivets of each row pass through both roof plates and one of the side iianges of the supporting /carline between the trough portion thereofand the depressed edge 14- which forms a seat for the lining boards. The lapping portions of the roof plates and the carline together constitute a plate-carline of box-like shape having great vertical and lateral stiffness. The roof plates are spaced above the top edges of the side piates, and their eaves ends 18 are flanged downloyer the outer sides of the side plates and are spaced a slight distance away from them. The downturned eaves anges 18 of the roof sheets are secured to the side plates at their corners by rivets 19 which go through the ends of the carlines The running boards 20 are bolted to angle iron cross ieces 21 which are supported at their ends y sheet metal brackets 22 which rest upon;l

the roof sheets over the carlines on each side of the ridge and are riveted'to the carline flanges.

The invention is not restricted to the details ol construction shown in the drawings. l claim the following as my invention: v

1. A metal car roof comprisingtrough shape carlines having outwardly projecting flanges along the tops of their side walls, roof plates supported on said carline flanges with their side margins lapping each other over the troughs of the carlines, and means for rigidly securing said lapping margins of said roof plates and said carline anges together on both sides of the troughs to form a hollow plate-cardine.

2. A car roof comprising trough shape .carlines having outwardly projecting flanges along the tops of their side walls, the side edges of said flanges being depressed to form supports for lining boards, roof plates supported onvthe top portions of said carline flanges with their side margins lapping each other over the troughs' of the carlines, lining boards arrangedbetween said carlines with their ends between said roof plates and the depressed edges of said carlinel langes; and means for rigidly securing said lapping margins of said roof plates and said carline flanges together on both sides Y`of the troughs to secure said lining hoatrds in place.

insens 3. A metal car roof comprising side plates channel carlines having outwardly projecting flanges along the tops of their side walls,

the ends of said carlines being bent' down f85 over the side plates, roof plates supported on said carlines with their side margins eX- tending across the channels and each riveted to both flanges `of each carline, said roof plates having their eaves ends turned down 10 'over the side plates, and means for rigidly f securing said eaves ends of said roof plates and said carline flanges to said side plates. 4. A metal lcar roof comprising side plates channel carlines having outwardly 45 projecting flanges along the tops of their side Walls, the ends -of said carlines being `bent down over the side plates, roof plates ,1" v supported on said carlines with, their side; margins extending across the channels and'p each riveted to both llanges of each carline, x said roof plates having their eaves ends i.
