`usefull Improvements ini-CarfRoofs, of which the following is a specication.

The object of my invention is to provide an efficient all metal load sustaining car roof, for steel frame cars, which is of such construction that the movements of the ear body in transit will not impose any twisting or warping` strains on the roof.

My invention consists ot a car roof coniprising a skeleton frame, load sustaining metallic roofing sheets-spanning the open spaces of said frame and supported thereon,

`said sheets having eorrugations extending lengthwise thereof, the corrugatio'ns of the side marginal portions of adjacent sheets overlapping and interlocking, and locking means passing through the overlapped inarginal portions and anchored to the oar and to said frame, whereby the sheets are seccnred together and to the Icar. My invention further consists of the parts and combination of parts as Will be moreffully hereinafter pointed out.

Fig. 2 isan end view of the same with portions broken away;

The end plate 10 is of angle iron, one inember oi which is bolted to the ridge pole and is provided with an enlarged seat 9 on the upstanding end 12 which enters a groove or recess formed in the iunderface of the ridge pole. 13 are bolts securing the angle iron 11 to the ridge pole; one of said bolts also -passing through one member of the end plate. .141 is afascia on the ends of the car to which the bracket `15 for'the' running' board is secured.
