UNITED STATES PATENT EEICE.
WILLIAM J. FRYER, JR., AND GEORGE H. JOHNSON, OF NEW YORK, N. Y.; SAID JOHNSON ASSIGNOR TO SAID FRYER.
IMPROVEMENT IN FIRE-PROOF MANSARD RQOFS.
Specification forming part of Letters Patent No. 14 1,215. dated July 29, 1873; applicati@ ld May 14, 1873.
To all whom t may concern:
Be it known that we, WILLIAM J. FRYER, Jr., and GEORGE H. JOHNSON, both of New York, in the county of New York and State of New York, have invented a new and Improved Fire-Proof Mansard Roof; and we do hereby declare the following to be a full, clear', and exact description of the same, reference being had to the accompanying drawings making a part of this specitication, in which-- Figure l represents an elevation of a Mansard` roof 5 Fig. 2, a vertical section 5 and Fig. 3, a transverse sect-ion of the same.
Our invention rela-tes to the construction of Mansard roofs tire-proof.
\V e will describe all that is necessary to a full understanding of our invention, and then clearly point it out in the claims. f
A is a continuous metal bed-plate laid on top of the front brick wall. B is a metallic beam placed at the'top line of the roof. C O C are upright metal rafters bolted to the plate at bottom and to the beam at top 5 the whole thus forming a rigid metallic framework. D are hollow baked clay tiles. E are ordinary slates, or imitation slates, placed on the outside ot' the tiles, and fastened thereto through the joints of the tiles. The baked-clay tiles are so formed on the ends f as to clasp the metallic upright rafters. The tiles are scored or roughened on the back to receive plaster iinish. The slates on the outside are more to give the usual finished appearance than as an additional precaution against iire other than the tiles afford.
The outside ofthe tiles may be coated with Portland cement or other composition to give it a smooth or ornamental appearance.
An inside'ventilation through the tiles can be securedby leaving holes in the lower and upper row.
By combining the metallic frame-work and hollow baked-clay tile-filling and outside covering of slates we secure, `first, anentrely tireproot' Mansard roof 5 second, one which is watertight and damp-proof, the air-'chamber rendering it cool in summer and warm in winter; third, a very light roof, and one which can be built up on any angle or curve.
On reference to the drawings it is apparent that the clasp of the tiles to the raking rafters secures to the tiles the lateral support necessary to form the angular or curved baked-clay Mansard roof. Vhen the tiles and rafters are in position they act as abutments the rafters to the tiles-transversely. The
same form and principle of an arch can be Y formed of solid instead of hollow materials, keeping to the same external outlines.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. A fire-proof Mansard roof formed of a
