IMPROVEMENT IN SHEET-METAL ROOFING.

Specification forming part of Letters Patent No. 140,582, dated July 8, 1873; application filed November 26, 1872.

To all whom it may concern:

Be it known that I, GEORGE F. LEONARD, of Newport, in the county of Orleans and State of Vermont, have invented certain Improvements in Roofing, of which the following is a specification This invention is applicable chiefly to metal and slate roofs; and relates to the construction and mode of attachment to the sheathing of the fastenings, by which pieces of slate and sheets of metal are secured in position. The nature of the said invention consists in the features of construction hereinafter described, by which the fastenings are protected from moisture where they are nailed to the sheathin g. Said invention also relates, in part, to the. features of construction hereinafter described, by which the joints between the metal plates, when metal plates or sheets are used, are protected from liability to leak, as hereinafter more fully set forth.

Figure 1 is a plan view, showing the con struction of apiece or section of metal roofing and its fastenings, made according to my invention. Fig. 2 is a vertical section of the same on a line parallel to the upper and lower edges of the roof. Fig. 3 is a vertical section through the roof on a line transverse to the plane of Fig. 2. Fig. 4 is a piece or section of slate-roofing constructed according to my invention. Fig. 5 is a vertical section of the same on a plane at right angles to the upper and lower edges of the roof.

AAare the strips of metal by means of which the main portions of the roof are secured to the sheathing B, on which it is laid. O is a cap, which is placed upon the upper edge of the roof, and which is made to fit upon the upper ends of the strips A A and the upper ends of the metal or slate which forms the body of the roof at that point. D D are strips of sheet metal which, in the construction represented in Figs. 1, 2, and 3, form the principal portion of the roof. The strips of metal A A may be of sheet-zinc or other suitable material, and are bent into the form, or substantially the form, shown in the drawings, and particularly represented in Fig. 2, so that the fastening between two strips of the roofing is made of a single piece of metal bent over at the top, as shown, so as to form a double descending edge or rib, a, descending outwardly from the joint both on its upper and under sides, so as to deliver the water which may fall upon it on the roofing D and away from the joint, and thus prevent the water from running down upon the partsb b, which are secured to the sheathing by means of nails driven through the holes 0 0, shown in Figs. 1 and 4. The strips of metal D D are turned partly upward at their edges, as shown in Fig. 2, so as to shed the water away from their edges and prevent its overflowing them, so as to fall upon those portions of the strips A A which are secured to the roof, and thus prevent any portion of the water from coming in contact with the nails which hold the strips A A to the roof; and to further assure the realization of this result, I propose to cap the edges of the sheets D D with strips of tarred paper, d d, as shown in Fig. 2, or some other equivalent substance, said strips d at being turned over the edges of the sheets D D, as shown. The sheets D D may be of zinc or other suitable metal, and may extend from the top to the bottom of the roof.

In the use of slate as a roofing-material the construction has to be somewhat modified. The strips A A, in this case, have raised portions formed therein to receive the cross-strips E E, which are so turned in the fold as to lap over the upper edge of the slates F F, over which they are placed, as shown, and thus prevent the water from getting'under the up per edge of the slates. The strips E E are, like the strips A A, made of a single piece of metal each, and fastened to the sheathing B by means of nails driven through holes in the edges, in a similar manner to that already described with reference to the strips A A, the principal difference between them and the strips A A being in the form given to the exposed portions, to adapt them to shed the rain over onto the slate below, as shown in Fig. 5. One of the strips E E is placed between the upper and lower edges of each two pieces of slate, as shown in Figs. 4 and 5.

I claim as my invention- 1. The strips A A, formed as described, with the exposed edges projecting downwardly over the main body of the roofing, and the edges where they are secured to the sheathing being extended under the main body of the roofing, as hereinbefore set forth.

2. The combination of the strips A A, constructed as hereinbefore described, with the sheets D D turned upward at the edges, which are overlapped by the strips A A, as hereinbefore set forth.

3. The combination of the strips A A and D D, and the sheets of tarre'd paper or other packing d d, as hereinbefore set forth.

4. The combination of the strips A A and E E, constructed as hereinbefore set forth.

5. The combination of the strips A A and E E, and the slates F F, substantially as hereinbefore set forth.
