UNITED Tras JOHN W. HOYT, OF SPRINGFIELD, MASSACHUSETTS.
lMPROVEMENT IN FIRE-PROOF ROOFING.
d Specification forming part of Letters Patent N o. 187,140, dated February 6, 1877; application led December 14, 1876.
To all whom it may concern Be it known that I, JOHN W. HOYT, of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Fire-Proof Roofing; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
This invention is in the nature of an improvement in lire-proof roofing; and the inveution consists in a fire-proof roof constructed without purlins, and with corrugated iron secured directly to the upright beams or rafters ofthe roof, the corrugationsof the iron being at right angles to said upright beams; and the invention further consists in covering the outer surface of the inclosure of the roof with asbestus, to the surface of which is secured the slating.
In the accompanying sheet of drawings, Figure l is a longitudinal section of my invention, and Fig. 2 a cross-section of same.
Similar letters of reference indicate like parts in the several figures.
Fire-proof roong has heretofore been constructed with purlins, to which the inclosingcovering has been secured as a foundation for theslates.
By my invention, however, I am enabled to dispense with the purlins, by securing the inclosing-covering directly to the upright beams or rafters of the roof, A representing such upright beams or rafters, which may be of the ordinary T form,'or any other desired. To the outer surface of these `beams ior rafters I secure, in any convenient and substantial mannen the covering B, which is formed of corrugated iron, so placed as to bring the corrugations at right angles to the length of the beams. This corrugated iron may be secured, as before stated, in any desirable manner, but it is preferably so secured with the aid of a cleat, a, bolted to the inner side of the beams. This cleat has a corrugated Lipper edge, which corresponds with, and fits into, the corrugations of thc corrugated-iron covering.
The corrugations of the covering B being at right angles to the beams or rafters A, the beams are held even more securely in position than would be the case if they were provided with purlins. This corrugated-iron covering may be covered on its outer surface with asbestus D, and the slating E secured thereon by bolts or wires passing through the slates and covering, to which they are secured in any desirable Inanner.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. A lire-proof. roof constructed with corrugated sheet-iron, secured to the beams or rafters of the roof, the corrugations of the sheetiron being lat right angles to the length of the beams, and the outer surface of the sheet-iron covered with asbestus or other non-combustible material and slates, substantially as and for the purpose described.
2. A fire-proof roof constructed with asbestus, in combination with slates or shingles, substantially as shown and described.
