METAL RooFlNG.

SPECIFIGAELION forming part of Letters Patent No. 237,133, dated February 1, 18,81.

Application tiled September 15, 1880. (No model.)

To all whom it may concern:

Be it known that I, L Lnwrs SAGENDORPH, acitizen oftheUnited States, residing at Staunton, in the county of Augusta and State of Virginia,have invented certain new and useful Improvements in Metal Roofing; and I do hereby declare the followin gto be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or fi gures of reference marked thereon, which form a part of this specication.

Figure l is a perspective view of a single sheet from a number. of which the rooting is formed; Fig..2 is a perspective view of one of the cleats for securing the sheets together and to the sheathing. Fig.3 is a vertical crosssection of two of the sheets united, showing the cleat nailed to the sheathing, but not bent up over the cap 5 and Fig. 4 is a cross-sectional view, showing two of the sheets united to form the seam, the cleats nailed to the sheathing, bent up over the cap, and the seam compressed as it appears in use upon the roof. Fig.5 is a sectional detail of the laying seam, and Figs. 6 and 7 are moditicationsof the standin g seam.

The invention has relation to metal roofing; and it consists in the improvements in the construction of the same hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings like letters ot'reference indicate corresponding parts in the several igures.

Heretofore great difticulty'has been experienced in constructing the standing seam of metal rooting to avoid the breakage resulting from the contraction and expansion caused by heat and cold upon the metal sheets of which the roof has been composed. Rivets, eyelets, staples, indentations, and the like have been employed to secure the standing seam; but they are all open to the same objection-viz., the contraction A and expansion of the metal will cause them eventually to break or tear loose and permit leakage at the seam. My object is to provide a standing seam for metal roofing that will not be open to this objection, and I will now proceed to describe in detail its construction.

A designates one of the metal sheets of which theroof is to be formed, provided at one side with a single upturned vertical ange,B,hav ing a series of slots, C, formed therein, and at the opposite side with a double flan ge, D,forrned by drst bending the edge of the sheet up and then bending the single lian ge thusformed outwardly and down to form an inverted U, one arm ofwhich,however, is shorter than the other, as shown in the drawings. In the curve ofthe inverted-U ange is placed a packing, a, of felt@ er, or red lead, or any other suitable 'material tha -wll exclude Water and save the meta-l from breaking when the standing seam is being compressed or hammered. Felt, however, is preferable for conveniently handling. This packingtakes the place of solderin doubleseaming and prevents the roof from rattling, as it acts as an insulator. I also place the packing between all the joints of the roof, the' cross-seams, standing and hooked seams. By using the packing the fire-pot is unnecessary, and the danger ot' re to the building while rooting it is removed. Besides, the packing will not break as solder does, and the durability of the roof is increased.

The slots C may be either round or oval, or

as shown iu the drawings, and may be made with a punch or knife, or in any other suitable manner.

I intend in practice to make the sheets by machinery, although, as is obvious, they may be readily made by hand.

E designates the cleats,which are also of sheet metal,andwhich are to be passed through-that is, inserted in-the slots C in the. single flange B. The ends of the cleats E, that project from the outside of the flange B, are to be bent down, as shown, and secured by the nails or screws F, driven through the holes G punched in them, to the sheathin gH. The other ends of the cleats E, which are the longer ends, are bent down upon the inside of the flange B, as shown. The double lange D ot' another sheet, A, is then placed over the flange C and the cleats E and pressed down to place, and the ends ofthe cleats E,which now project from beneath the double flange D, are then bent up and back over the top of the double llange D, and then down againstits side, as shown in the drawings. A seamer is then used to compress the several parts tightly together to exclude water. By this construction each sheet contracts and ex- IOO pands independently of the other, as also do the cleats, so that no strain comes upon the seam or the metal of which it is formed, and the seam cannot therefore break or tear loose, as iu the constructions hereinbefore referred to.

From the foregoing description, taken in connection with the drawings, the construction and operation of the device will be readily understood.

Itis practical, simple, durable, and may be cheaplyconstructed, and possesses advantages not heretofore attained.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In testimony whereof I affix my signature z5 in presence of two Witnesses.
