SHEET-METAL ROOFING.

Specification of Letters Patent.

' To all whom it may concern Be it known that I, KAnnR-o'rri, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, haveinvented certain new and useful Improvements in Sheet-Metal Roofing, of which the following is a specification. Thisinvention relates to sheet metal roofmg.

I am aware that there are any number of different kinds-of roofing on the market which are provided with peculiar and'in terlocking seams for holding the sheets together, but I have found in the manufacture-of sheet metal roofing a growing desire among a certain class of people to cover their own buildings, and as those people are rarely provided with the necessary tools for properly fastening these peculiarly shaped hooked seams their eflorts result in leaky roofs. This condition has, to a certain extent, discouraged the use of sheet metal roofing on farm buildings for the reason that roofs of this'character laid by skilled workmen are too expensive for the class of people for which the present invention is intended. v

The object of this invention is to provide a simple and easy means for joining the side edges of sheet metal roofing ,to prevent water from seeping through the overlapping edges thereof.

I accomplish the object of the invention by certain means illustrated in the accompanying drawings, forming a part hereof, in which Figure 1 is a view in perspective of two sheets of metal roofing laid side by side with the adjacent edges of the sheets overlapping. Fig. 2 is a fragmentary detail perspective view of the overlapping edges of two sheets of metal roofing, showing the formation of the ribs for excluding the water Fig. 3 is a view similar to Fig. 2 except that the two sheets are separated.

In the drawings, 10 represents the body of the sheet metal material used for roofing purposes. Each sheet of metal is provided on one of its longitudinal edges with two vertically disposed V-shaped ribs 12, and the opposite edge of each sheet is bent upwardly to form the wall 14, and in addition thereto each sheet is provided with asufliciently overlap the edge of the adjacent sheet so as to permit the rib 12 nearest the edge to fit down over the similarly shaped rib 16 in the sheet below, while the second rib 12 will straddle the wall 14 on the sheet below. It will be noted that the operation of laying the sheets is extremely simple, and the ribs and wall as formed will absolutely prevent water from passing between the overlapped edges oft-he sheets.

It ofttimes happens that water will seep through many of the interlocked joints in sheet metal roofing, this being common p'articularly-where the overlapped surfaces of the sheets follow the same common plane and curve, on account of capillary attraction. For instance, it will be noted in Fig. 2 of the drawings that the V-shaped rib 12 in the upper sheet tightly hugs the rib 16 in the sheet underneath throughout the Patented Feb. 27,1912. application filed November 7, 1910. Serial no. 591,072.

edge containing the two ribs 12 is laid to were provided with several ribs of the samefl character, it is quite likely that water would work its way between the overlapped edges of the sheets. To remove all danger of water passing between the overlapped edges on account of capillary attraction I provide, as before stated, each sheet with an additional rib 12 which merely forms a passageway for the wall 14 formed on the sheet underneath. The wall 14 is formed so that its height will be somewhat less than the internal height of the rib above so that an uninterrupted air space is formed theentire length and on both sides of the terminal edge of the sheet containing the wall 14. Hence, if, on account of capillary attraction, water should climb over the rib 16 1n the underneath sheet it would be caught and carried away in the channel existing between the foot of the rib and the foot of the wall 14, and the said wall would prevent progress of the water transversely of the to be driven in an location along the ribs and obviates the ifliculty of bringing the holes of theplates in reglster, whichwwould occur were the holes previously formed in the roof plates? The nails are all providedwith lead washers to close the openings around the bodies of the nails, and the latter are driven through the rib 12 and rib 16, as shown in Fig. 2 of the drawings.

Having thus fully described my said invention, what I desire to secure by Letters Patent, is-

' A sheet metal roof consisting of a plurality of metal sheets with overlapping edges, each sheet provided along one side edge with two vertically disposed ribs of the wideinverted V shape and the opposite edge of the sheet turned upwardly at a right angle to form a wall and a vertically,

disposed to and bein ,so t at when the adjacent metal sheet is laid over said wall an uninterrupted air space wiIl remain on both sides and over the top of said wall and the nails driven rib formed in said sheet adjacent through the ribs adjacent to the onecovering said well, to secure the said roofing sheets.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 26th day of October, A. D. one thousand nine hundred and ten.
