METAL ROOF.

SPECIFICATION forming part of Letters Patent No. 451,650, dated May 5, 1891.

Application tiled August 9, 1890. Serial No. 361,523. (No model.)

To @ZZ whom, t may concern:

Be it known that I, CHARLES R. EVERSON,

. of Macedon,in the county of Wayne and State of New York, have invented a new and useful Improvement in Anti-Rust Metal Roofs, which improvement is fully set lforth in the following specification and shown in the accompanying drawings.

My invention relates to sheetmetal roofs, more particularly tin roofs, for buildings, the design being to produce an anti-rust roof by joining to the sheets of tin small pieces of another metal--as sheet-zinc, for instancethe invention being hereinafter fully described, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a portion of a roof, showing my anti-rust tags in place in dotted lines; Fig. 2, an enlarged view of one of the tags, better showing its form and construction; Fig. 3, a cross-section on the line 3 3 in Fig. 2, and Fig. 4 a section on the dotted line 4 t in Fig. 2. Fig. 5 shows the adaptation of the invention to a standing lock.

Referring to the parts, A are ordinary sheets of roofing-tin, and B the anti-rust tags. The sheets of tin are overlapped and interlocked at their contiguous edges, as shown in Fig. 3, and soldered together when placed upon the roof. The tags I preferably form with a tin backing or holder a, holding a small sheet of zinc b. The upper edge c .of the holder c is folded over the zinc and closely hammered down thereon to hold the parts together, and both piecesare pierced at a point near the center of the zinc sheet to receive a nail d to secure the tag to the roof-board C. In piercing these parts the punch passes through the zinc rst, and both parts are bent downward or cupped around the hole to receive the head of the nail, as shown in Fig. 4, the cup of the zinc resting in the cup of the tin. This forms an additional means of sef curing the sheet of zinc to the tin backing, as

it tends to preventa lateral or sliding motion of one piece upon the other. At its lower edge the holder a is turned or hooked under the lip or fold e at the upper edge of the lower sheet A, the holder lying against the roofboard. The adjacent sheet A above is placed over or upon the tag, and, like the latter, is

bent at its lower edge under the fold e of the sheet below it, its lower fold also including the lower part of the tag. When the parts are thus put together and hammered down, each sheet A is over and in contact with the zinc portion of one or more of the tags B. These tags, being secured to the sheet A and nailed to the roof-boards, serve also to secure thetin root to the roof-boards of the building.

Then applied to a standing lock, (shown in Fig. 5,) the holder a of the tag is made long and bent t0 the forni of an L, as shown, the zinc I) being laid upon the foot or lower part of the holder, or the part that rests upon the roof-boards. In this construction the upper edges of the respective holders care bent down over the upturned edges of the respective sheets of tin A and hammered closely down, the lower or under faces of the holders being in contact with the roof-boards.

In constructing the roof I prefer to place twotags at each of the long sides of the sheets of tin A and one at each of the short sides or ends, as shown in Fig. 1. By this construction each sheet of tin is in contact with one or more of the zinc pieces, which serves to prevent the rusting of the sheets of tin."

.,Vhat I claim as my invention is l. A roof consisting of sheets of tin joined at their respective contiguous edges to form a tight covering, in combination with tags formed with pieces 0f metal other than tin, secured to the edges cf each of said sheets of tin in positions to underlie the adjacent sheets of tin and be in contact therewith, substantially as shown and described.

2. A metal roof consisting of sheets of tin locked or joined at their respective contiguous edges, in combination with tags of metal secured to the edges of each of said sheets of tin at the seams between the latter, said tags each consisting of a sheet-metal backing or holder ct and strip of metal Z9 other than tin held by said backing or holder, the latter being in contact with one sheet A of the roofingtin and the part b in contact with the adjacent sheet of roofing-tin, substantially as described, and for the purpose set forth.

3. A roof consisting of sheets of tin joined at their respective edges to form a tight covering, in combination with metal tags secured to the edges of each Vof said sheets of tin, said roo tags each consisting of a sheet-metal holder a In witness whereof I havehereunto set my and strip of metal Z) other than tin, said hond, this 24th day of June,1S90, iu the presholder being turned at 011e edge down over ence of two subscribing Witnesses.

:u1 edge of the part Z), and a nail piercing CHARLES R. EVERSON. 5 said two parts ce and b, the parts or pieces a Witnesses:

and b being` cupped to receive the head of E. B. XVI-IITMORE,

the nail, substantially as shown :md described. M. L. MCDERMOTT.
