IMPROVEMENT IN METALLIC-ROOFINGS,

pecifichtion forniing part of Letters Patent N05 154,649, dated September 1, 1874; application filed July 3, 1874.

To all whom it may concern:

Be it known that I, SETH Uoxmf Oskaloo'sa, Mahaska county, Iowa, hareinvented a new and useful Improvement in "Metallic .Itoofin g, to be known by the name American Rooting, of which the following is a specification:

, The object of this invention'is to construct V a new and improved kind of metallic roof; and

it consists in the provision made for-counteracting the effects of expansion and contraction incident to changes of temperature, the said provisions being in the corrugations and manner of attaching 'themetal to the roof hoards or timbers.

In the drawing, Figure 1 is atop view, with 1a portion of the corrugated rooliug' broken away to showthe flanged strips or rails on which the corrugated rooting rests and to which it is confined and .Fig. 2 is a cross-sec tion of Fig. 1, taken onthe line a: w'.

Similar letters of reference indicate col-re spending parts.

A-are, the roof-boards or sheathing-W B represents double-fianged metallic strips or rails, attached to the roof-boards or rafters by means.

of nails or screws through their lower flanges. C are cl sps attz ehed' to the under side of the metallic roofing, which clasp'sare bent so as to receive the upper flanges of strips B; D-is the corrugated metallic roofing. E represents the corrugations. The roofing Dis formed, of

sheets of metal soldered together, so as to makea continuous water-proof sheet or root; and the sheets, (the whole or a 11311,) provided .with the clasps C, are slipped onto the strips 3 B, and thus confined to the roof. This allows the roof to expand and contract in one direction, while the corrugation? E allow it to ex- "pond and contract in the other. The clasps G "confine the metallicroof to the boards or' ratt- 1 ers; but the edges are fastened by means of. screws F, which pass through slots in they metal sheets. Instead of continuous strips B to hold the c foot" down, a succession of screws may be driven into the roof. boards. or timbers, with the heads-of which the clasps C'may engage; but I preferthe continuous strips or rails B, ,4

G represents the air-space between the metallic roofin g and the roof-boards or sheathing. This air-space serves as a shield. to protect the building from fire onthe This space Gr .may be greater or smaller, as may be desired, 1 according to the depth of the flanged strips or p rails B; and, as air is a good non-conductorof beat, this space will. prove a protection in all e ordinary cases.
