METALLIC-ROOFING CONSTRUCTION.

ham it may concern: l BZ i t kn w t at 1, CHARLES Seems n of the United States, re siding at Celina, in the county of Mercer and s a f Ohi have invented a new and use- M t l-Roof Construction, of which the f ll i i a speclficatlon.

I? T hisv inventlon relates to an improvement in sheet metal roof constructlon, more espei ll 1 the manner of making standing Seams that shall be secure, water tlghtand easily separated and reformed. This is a Ihost valuable pr perty 111 roof construction as a defective. plate or section can be reil o'ved from a roof, a new one substituted, the seam closed as tightly as before. I h bject therefore of th1s lnventlon is to labor saving means for closing earns of metal roofs which may be glied' and as readily removed, and high 11 make a perfectly secure o1nt, 3' t th ame time anchor the roof to the eathing below, thereby preventlng roof from rattling and belng blown off i th prevalence of very hlgh wlnds.

' th accolnpanylng draw ngs:F1gure 5, ective view of a portlon of a metal constructed in the manner hereinafter c jb i Fig. 2 1s a cross section of a di seam, the several parts be ng W11 di onnected. Flg. 3 1s apers GGUVB portion of the seam cap. 1g. 4 s inilar view of the cap packing. Fig. 5 1s oss sectional view of a modified form of imilar numerals of reference indicate the e p t-, 'in all the figures of the drawings. hew d n sheathing of a roof, indlcated c numeral 1, is covered in the usual er by strips or plates of sheet metal, as ti Two of such strips 2 and 3 are him the drawing with their respective acent edges 4 and 5 turned to an upright a on and at a little greater angle than for a standing seam, so that when the es 2 and 3 are placed in position, the up- (1 edges 4 and 5 will be separated at the 8 represented in F1g. 2. f re the sheet 2 is placed against sheet l mber of anchor strips f sheet metal 2 led tothe sheathing 1 a suitable disapart and bent over the upturned or 5 of the roofing plates 2 9r 3.

and 9 to form channel-ways in which are,

seated and clamped the edges of a piece of felt 10 or other suitable packing materialwhich has been reviously folded somewhat in the shape of t 1e letter as M clearly repre sented in Fig. 2.' The side folds 11 and 12 of the packing material as previously mentioned, are supported .by the inwardly turned edges 8 and 9 of the cap sides 8 and 9 and rest against said" sides. The central fold 13 of the packing extends downwardly between the side folds, and when the cap 7 is placed over the separated upturned edges 4 5, the central fold 13 of the packing passes between said upturned edges 45, while the outer folds 11 and 12 lie against their outer sides. After the cap 7 has been driven down on the upturned edges 4 and '5 as far as it will 0, the several parts are clamped or presse together by an ordinary cap squeezeror other tool, presenting then the appearance illustrated in Fig. 1.

The anchor strips 6 which at this time are sticking out between the ends 8 or 9 of the cap are then folded over the ca and bent down on the opposite side as clear y indicated in Fig. 1.

A standing seam, constructed as above described is strong, air tight, water tight, and, if asbestos is used, fire proof, and at the same time easily separable. The anchor strips through their attachment to the sheathing and to the seam, hold the metal roof closely against the sheathing and prevent it from rattling and from being blown off the house by a high wind. The packing prevents moisture from creeping up between the folds of the metal and protects the metal from rust.

A cheaper cap and one more quickly applied is represented in Fig. 5 and as there shown consists of a sheet of metal 15 doubled upon itself and clasping between the folded 17 spread outwardly a short distance below the fold 20 to receive the upturned edges 4 and 5 of the metal plates 2 and 3.

Havin thus described the invention what is claime l is 1. A metal roof seam comprising two sheets of metal each having an adjoining standing edge, a cap for covering said upstanding edges having channel ways formed at the bottom of "each side, a folded packing stri supported in said channel ways and exten 'ng up into the cap, and ada ted to separate said upstanding edges and t e sides of the cap one from another, and an anchor strip extending from a fastening beneath the metal roofing over said cap.

2. A cap for metal roof seams comprising a folded sheet of metal having its lower edges turned inwardly to form channel Ways, and a strip of folded packing within said cap and supported in said channel ways.

3. A packin strip for a metal roof seam to be used Wit. a cap for covering the upturned ends of metal sheets, consisting of a stri of waterproof material doubled upon itsef and then each side doubled again to form an M-shaped strip.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

CHARLES SPORNHAUER.
