UNITED STATES PATENT OFFICE7 ROWELL GOLBY, OF FREEPORT, ILLINOIS.

-IMPROVEMENT IN SHEATHINGS FOR BUILDINGS. l

Specification forming part of Letters Patent No. 154,843, dated September 8, 1874; application filed June 6,- 1874.

To all whom yit may concern Be it known that I, ROWELL OoLBY, of Freeport, Stephenson county, Illinois, have invented a new and Improved Mode of Govering Buildings, of which the following is a specification In the accompanying drawing, Figure l represents a front view; Fig. 2, a vertical transverse section on the line c c, Fig. l, of my improved mode of covering buildings and Figs. 3 and 4 respectively show front view and vertical section of a modification of the same.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide, for the purpose of covering buildings, a veryneat, substantial, and ,durable mode of rooting and` Weatherboarding, made of water-proof paper, metallic sheets,or other folding material, so as to imitate courses'of shingles and clapboards.

The invention consists in a fire-proof roofing or sheathing for buildings, which is formed of metallic orpaper sheets and a filling of mortar, as hereinafter described.' v

In the drawing,\A represents the roof qr wall of any building, and B the sheets or strips of prepared Water-proof and lire-proof paper,

wood, sheet metal, or other suitable materiall employed for covering the outerweathery surface of the roof or wall A. The stripsI or sheets B are cut oi' suitable width for resembling shingles or clapboards, and of thelength of the space to be covered. A strip, B,is placed along the lowermost part of the surface, and a cleat, C, preferably of the same material as the strips, being one or two inches wide and of corresponding thickness, tacked along the upper edge of the strip until the sameis securely fastened along its whole length..

A coatof mortar made of common clay, fireclay, plaster-of-paris, water-lime, or any other good non-conducting material, is then applied,

so as to ll up the space above the cleat, which would otherwise be empty, and form, at the same time, a solid body or support for the strip, which is then folded snugly and smoothly in upward direction over the cleat, nails, and mortar. Another strip, B, is then placed along i the upper edge of the Aone just folded up, and is fastened in a similar manner by a cleat and nails along and with the edge of the lower strip. The mortar is then again applied and the strip folded up over the cleat. This operation is continued until the whole surface is neatly finished, the upper course being fastened by a cleat or strip of the paper or other material nailed over the same.

The cleat furnishes a firm support for the heads of the nails by preventing injury to the sheets in nailing, holdin g the sheets more rmly together, and furnishing a straight edge to fold over.

Instead of the folding lapjoint with cleat, the folding lock-joint may be employed, by which the place of the cleat is supplied by folding down the upper edge of the lower sheet or strip, asV shown in Figs. 3 and 4, though an additional cleat for` supporting thel nails may also be used. I prefer, however, on aecount of the greater simplicity and ease of application, the folding lapljoint with cleat first described.

If paper is used asa covering material, a paint of Spanish brown or other suitable color mixed with linseed-oil is given once in five years, or oftener if deemed necessary.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The covering for buildings, formed of sheets B, lfolded and secured by nails, and the filling of mortar interposed between the sheets and the roof or wall, as shown and described.

BOWELL COLBY.
