FREDERICK M. WHYTE, OF TARRYTOWN, NEW YORK,v ASSIGNOR TO HUTCI-IINS CAR ROOFING COMPANY, 0F DETROIT. MICHIGAN, A CORPORATION OF lVIICI-IIGAN.

CAR-ROOF.

Specification of Letters Patent.

Patented Dee. 5, 1916.

Application filed October 13, 1913. Serial No. 794,978.

To all whom t may concern Be it known that I, Fnnnnnioii MViir'rn, a citizen of the United States of America, residing at rTarrytown, in the county of festchester and State of New York, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to car roofs of the type comprising a series of separate roofing plates which are independently movable and have weather proofing connections.

Various constructions have heretofore been devised in which the roofing plates are flexibly supported upon carlines. lVith the present construction the plates are rigidly secured to the carlines, but are flexible in relation to each other, the flexible connec tions being also weather proof.

In the drawings: Figure l is a longitudinal section through a portion of the car roof intermediate the ridge and eaves; Fig. 2 is a section in the plane of the ridge purlin; Fig. 3 is a transverse cross section through a roofing-sheet; and Fig. #l is a view similar to Fig. l, showing a modification.

A is a carline for si'lpporting the roof structure` and which, as shown in Fig. l, is of a U-shaped cross section having out- 'ardly-extcnding flanges B.

C are the roofing plates extending transversely of the car, preferably from cave to eave.

Instead of arranging the sheets C to extend from carline to carline, as is the more usual practice, these plates are supported intermediate the sides of the sheets upon the carline and are preferably rigidly attached thereto by riveting the flanges B to the plates as indicated at I). The edges of adjacent plates are, however, free from each other so as to permit of the independent movement and the flexing of the roof structure. A weather-proof joint between the plates is obtained by suitable weather-proofing means, such as U-shaped caps E embrao ing the opposite flanges F at the edges of the sheets, said caps being also preferably provided with laterally-extending flanges G.

lith the construction as described, each of the plates C is rigid in relation to the particular carline upon which it is supported, but the flexible weatherproof joint between adjacent sheets permits of free relative movement thereof to compensate for weaving of the car fralne.

In Fig.l il, a .modified construction is shown, in which the carline A is arranged above the sheet C and is riveted or otherwise rigidlv secured thereto. The construction is otherwise sin'iilar to that shown in Fig. l, the edges of the sheets being provided with similar weather-proofing means.

As the roofing plates are rigidly attached to the cai-lines it is unnecessary to provide any other means of securing them to the car, and to obtain greater flexibility, the down-turned flanges Il at the eaves are slightly spaced from the fascia of the car so as to permit freedom of movement. The arrangement of the carlincs intermediate the sides of the sheet also .increases the strength of the latter and avoids the necessity of intermediate support by purlins. If

desired, however, a rigid purlin I may be' used, which, as shown in Fig. 2, is formed of a metallic beam having flattened portions .l for attachment to the carlines and intermediate depressed portions K. The running board L may be secured by brackets lVI which are secured by rivets N to the roofing-- plates and ridge-purlin.

The weather-proofing caps E preferably extend from cave to cave and are secured in position by bolts f) which pass between the upstanding flanges lf. These bolts mav be rigidly attached to the caps, as by a shoulder l beneath the cap and riveted head Q thereabove. The bolts are secured to the underside of the plates by clips R, which are detachablv secured to the bolt Shanks by suitable means, such as wedge-keys S.

IVhat I claim as my invention is.:

l. A car roof, comprising a series of roofing plates, cai-lines to which said plates are rigidly secured, and weather-proofing connection between adjacent plates permitting freedom of relative movement.

A car roof, comprising a series of carlines, roofing plates rigidly supported upon said carlines and otherwise free from the car and from each other, and weather proof* ing means between said plates.

3. A car roof, comprising a series of carlines, roofing plates rigidly supported intermediate their edges upon the respective carlines and having upstanding marginal flanges free from each other, a ruiming board supported upon said plates above said oarlines, and a Weather-proofing cap for said npstanding flanges extending from eave to eave and beneath said running board.

4. A cai' roof, comprising a series of interinediately ti'ussed and intermediately, rigidly supported roofing plates extending from eave to eave, and ieXible Weatherprooiing means between adjacent edges of said plates.

5. In a oar roof, the combination With intermediately supported adjacent roofing plates extending from eave to eave, 'upstanding flanges at the adjacent edges of said plates, caps embracing said Hang'es extending from eave to eave, and securing means for said caps extending between said anges.

In testimony whereof I ailix my signature in presence of two witnesses.
