LONGLEY LEIVIS SAGENDORPH, OF PHILADELPHIA, PENNSYLVANIA.

M ETALLI Q ROOFING.

SPECIFICATION forming part of Letters Patent No. 425,830, dated April 15, 1890.

Application filed January 24, 1890. Serial No. 337,952. (No model.)

To all whom it may concern:

Be it known that I, LoNeLEY LEwIs SAGEN- simple and effective means for uniting r each side of said openings.

locking together the sides of metallic roofingsheets, the means employed being such as that the roofing-sheets may be rolled in a compact form for shipment and the seam-cap formed after having arrived at its destination, as will more fully hereinafter appear.

In the accompanying drawings, Figure 1 is a plan View of the endportion of a roofingsheet, showing the position of the cleat-openings before the side flange and cap-seam are formed, the dotted lines indicating Where the bends are made in the sheet to form said side flange and cap. Fig. 2 is a View similar to Fig. 1, showing the preferred form of cleat in position in the cleat-openings, in which position the roofing-sheets may be rolled for.

shipment if desired. Fig. 3 is a perspective View of the end portions of two roofing-sheets as placed together before the seam-cap is formed, the dotted lines indicating where the bend will be to form said cap. Fig. 4 is an end View of a roofing-sheet having the side flange and seam-cap formed with a cleat in position in said cap. Fig. 5 is a perspective View of two roofing-sheets in position to be locked, the View being taken from the reverse side of that shown in Fig. 3; and Fig. 6 is a similar View with a portion of the seamcap folded to place. Fig. 7 is a cross-section through the standing seam, taken between the cleats; and Fig. 8 is a similar view taken through said seam and one of the cleats.

My invention consists in forming near the outer edge of the roofing-sheet and on that side from which the overlapping seam-cap A will be formed the cleat-openings a, into which the end portion b of the cleat B rests, as shown, the shoulders I) of the cleat resting against the metal of the roofing-sheet at The cleat-openings are formed, preferal'ily, before the seamcap A. is bent, and the tongues 19 of the cleats B are then put to place, as shown in Fig. 2, in which position the roofing-sheet may .be rolled in a compact form for shipment with the cleats in position.

' The seam-cap A and flange G of each roofing-sheet may be'bent and formed in the factory before shipment, as shown in Fig. 4, or after having been put to place 011 the roof, as shown in Figs. 3, 5, and 6. In either case the cleats B are bent and formed with the seamcap A after the tongue I) of each cleat has been put to place, as shown in Fig. 2. It will be seen that the shoulders I) of each cleat fit up against the roofing-sheet at each side the cleat-openings a, and that the apex bend of the seam-cap A is formed on a plane below the cleat-openings, (before bending,) as shown in Figs. 3, 5, and 6, and when bent to position theapex of this seam-cap A is on a plane above said openings, as shown in Fig. 4, in which position the shoulders I) of each cleat are bent below the apex of the seam-cap.

The object in having the seam-cap and cleat bent in such a manner as that the shoulders b of each cleat when bent will fall below the apex plane of the cap is that the cap cannot be elevated to slip or become loosened from the cleatthat is, aft-er the cleat is thus bent and nailed to the sheeting the cap A cannot be elevated, on account of the shoulders formed on each cleat on the inside of the seam-cap.

My invention is applied as follows: Vhen the vertical flange O and sea1n-oap A are formed before leaving the factory, as shown in Fig. 4c, the cleats B are nailed to the sheeting, and the flange C of the adjacent sheet is then put to place between the upward and downward bent portions of the cap, the body portion of said adjacent sheet resting on the cleats, in which position the seam-cap and cleats are compressed or pinched together with suitable tools, as shown in Figs. 7 and 8. When thus united, it is impossible for the wind to blow off or loosen the roofing-sheets, for the reason that any upward tendency of the cap A is prevented by reason of the shoulders b on the cleats B. When the sheets and cleats are shipped in a roll and the flanges and seam-caps formed on the roof, as shown in Figs. 3, 5, and 6, the cleats are first bent gagcd from said cleats, and at the sametime admit of ample expansion and contraction.

The seam-cap thus formed is freeof any over-. lapping outside cleats,which is a great advan-. tage, as all outside cleats are liable to rust or.

cause the cap-seam at those points to rust and I leak. The seam-cap, being free of any overlapping cleats, presents a neater appearance 1 and will last longer. The cleats, being protected by the seam-cap, will last much longer, which renders the connection between the roofing-sheets more secure. A portion of surface metal is dispensed with, lessening the cost of manufacture. The cleats, being bent with the seam-cap, enable the roof to be ap-; I

plied quickly and economically.

' What I claim as new, and desire to secure by Letters Patent, is-

1. The means herein shown and described for connecting and anchoring metallic roofingplates to the sheeting, consisting of a slot formed in the downward extension of the seam-cap and a shouldered cleat, the narrow tongue portion of said cleat restingin said slot and the shoulders of said cleat resting against the roofing-sheet at each side of the said slot as and for the purposes set forth.

2. A metallic roofing-sheet having at one side the vertical flange. O and at the other sidethe seam-cap A, the latter having a slot at in its downward extension, in combination with a shouldered cleat B, the tongue portion b of said cleat resting in said slot, the shouldered portions 12 b of said cleat resting against said cap-seam at each side of said slot on the under surface of said cap, as set forth.

3. The metallic roofing-cleat B, having the narrow tongue extension I) and shoulders I) b, said cleat being so bent and formed as that said shoulders will fall below the apex bend thereof, as and for the purposes set forth.
