UNITED STATES PATENT OFFICE.

JAMES J. MCCARTHY, OF AUSTIN, ILLINOIS, ASSIGNOR TO THE CHICAGO- CLEVELAND CAR ROOFING COMPANY, OF CHICAGO, ILLINOIS.

CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 590,272, dated September 21, 1897.

Application filed April 3, 1896- To all whom it may concern:

Be it known that I, JAMES J. MCCARTHY, a citizen of the United States residing in Austin, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a partial plan view, part of the roof being removed. Fig. 2 is a partial vertical cross-section. Fig. 3 is an enlarged detail, being a partial vertical cross-section. Fig. 4 is a partial longitudinal vertical section on line 4 4 of Fig. 3. Fig. 5 is a similar view showing a modification.

My invention relates to car-roofs, and has for its object to provide an improved construction whereby leakage will be effectually prevented and whereby danger from fire will be reduced to the minimum; also, to improve the construction of car-roofs in general.

I accomplish the objects of my invention as hereinafter specified and as illustrated in the drawings.

That which I regard as new will be set forth in the claims.

In the drawings, 6 indicates the sides of the car; 7, the roof proper; 8, the foot-boards; 9 10, vertically-arranged strips at the eaves of the car and arranged a short distance from the sides of the car, as shown in Figs. 2 and 3.

11 indicates the ridge-pole.

12 indicates the rafters, which, as shown in Fig. 4, may be of somewhat inverted-T form,

or, as shown in Fig. 5, may be reversed, as indicated at 13.

In the form of construct-ion shown in Fig. 4 gutters 14 are provided at each side of the central portion of the rafter, which forms a rib 15 and is secured by means of an intermediate block 16 to longitudinal beams 17-, upon which the roof proper is secured.

In the form shown in Fig. 5 the rafter is secured directly to the beams 17 and is provided at its under side with a rib 18, between which and the usual longitudinal supporting-joists 19 corrugated metallic roofing-plates 20 are secured. 7

As best shown in Fig. 4, the edges of the roofing-plates 2O abut against the sides of the rafter, and said plates are secured in place Serial No. 586,132. (No model.)

by an auxiliary plate 21, the edges of which are corrugated to fit the corrugations in the plate 20, the intermediate portion of said plate 21 being fiat and being secured between the rafter and the block 16, a spike 22 serving to hold all the parts together. The auxiliary plates 21 project at each side of the supporting devices over and rest upon the roofingplates 20. This forms a loose connection between the roofing-plates and the plates 21. The arrangement of the intermediate plates over the roofing-plates serves to effectually prevent leakage, and also by making the barrier between the roof and the interior of the car more complete affords a better safeguard against fire. The upper ends of the roofingplates 20 extend up into the ridge-pole 11, as shown in Fig. 3. The lower ends of the roofing-plates terminate at the sides of the car and discharge water into the space between the side of the car and the strips 9 10.

The roofing-plates are preventedfrom slipping out of place by a series of stop-blocks 23 secured opposite the lower ends of said plates, as shown in Fig. 1. By this construction when it is desired to remove the roofingplates all that it is necessary to do is to re:

move the stop-blocks 23, as the plates, arenot nailed in position. This is especially advantageous, as it permits the plates to adjust themselves to the shifting or racking of the car and also permits of the ready removal of the plates for reuse in case of wreck. Furthermore, by the use of the auxiliary plates 21 a complete barrier of. metal is provided, which is an effectual safeguard from damage by fire. are an eflicient protection against leakage. Should any water leak between the plates 20 and 21, it will be caught and carried to the edge of the car by the gutters 14 in the rat ters. In this respect the construction of rafters shown in Fig. 4 is that which I prefer.

I have described the construction 'of my improved car-roof in detail, but Ido not wish to be limited to such details of construction, as many modifications may be made without departing from the spirit of my invention.

That which I claim as my invention, and desire to secure by Letters Patent, is

1. In a roof, the combination with support- Such auxiliary plates also- ICO ing devices, and roofing-plates at each side thereof, of intermediate plates connected to said supporting devices and projecting at each side thereof, and extending parallel with and fitting closely upon the roofing-plates, forming practically a continuation of the roofingplates, substantially as described.

2. In a roof, the combination with rafters, and corrugated roofing-plates at each side thereof, of intermediate corrugated plates connected to the rafters and projecting at each side thereof, and extending parallel with and fitting closely upon the roofing-plates, forming practically a continuation of the roofingplates, substantially as described.

3. In a roof, the combination With rafters,
