READY-MADE ROOFING.

SPECIFICATION forming part of Letters Patent No. 636,022, dated October 31, 1899.

Application filed July 12, 1899. Serial No. 723,525. (No model.)

To aZZ whom it may concern:

Be it known that we, GEORGE D. CRABBS, residing at Hartwell, and WILLIAM H. PEN- DERY, residing at Lockland, in the county of Hamilton and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Ready-Made Roofing, of which the following is a full, clear, and exact description, reference being had to the IQ accompanying drawings, forming a part of this specification.

Our invention relates to that class of roofing known as ready-made roofing, usually consisting of a body portion of cement of about one-eighth of an inch in thickness, having a bottom layer of paper and a top layer of burlap embedded in the top surface of the cement. v the factory ready to be taken out and to be applied to roofs as the occasion requires.

The object of our invention is to provide a roofing of the above character which shall be cheap and simple in its construction and which from the formation of the lap at the 2 5 seams shall be both weather and water proof and shall be able to withstand the Winds which under ordinary constructions tear roofings of this character from their fastenings.

The novelty of our invention will be here- 0 inafter set forth, and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a roof having thereon our improved roofing with one of 3 5 the joint laps raised in position to show the manner of application of the same. Fig. 2 is an enlarged sectional side elevation at one of the joints before the last lap of the burlap is brought down and cemented over the heads 0 of the fastening-nails. Fig. 3 is a corresponding view showing the joint completed.

The same letters of reference are used to indicate identical parts in all the figures.

A represents the roof of a building to which the burlap strips of our improved roofing B are applied, in this instance the strips being laid horizontally on the roof, though, if de sired, they might be arranged vertically.

Each strip or roll of roofing material is com- This is made up into rolls in posed of a body portion 0, of cement of the usual or any suitable construction, such ce inent having as per ingredients usually asphaltum, with which is mixed asbestos fiber or other ingredients suitable to form a pliant cement body portion, and to the under side of which and of equal width is secured a web of paper, and to the top side of which is secured, by being embedded therein, a strip of burlap c. This strip of burlap on one edge of the cement portion is flush there with, but at the opposite edge extends be yond, so that it can be turned back on itself, as seen at f, Fig. 2, where at the unturned portion it is stitched together, as at d, and from that point forms a flap 6, extending beyond the edge of the strip, as shown.

In laying the roofing the edge of the strip having the overlapping flap c is laid over the edge of the adjacent strip, as seen in Figs. 2 and 3, and is pressed down to form a tight joint, and then a row of nails g are driven through the double lapped portion fof the burlap and through both overlapped portions of the strips into the roof, and finally the overlapping strip e of the burlap is brought down to cover the heads of the nails and is embedded in a coat of cement or paint ap plied to the adjacent surface of the underlying strip to form a close tight joint, as seen in Fig. 3. By this construction we are enabled not only to cover the heads of the fastening-nails at the joints, but to secure them through both portions of the cement body portion of the roofing and through three thicknesses of burlap, the upper two thick nesses of which are stitched together, and then when the overlapping flap is closed down and cemented the whole forms a very rigid joint, which not only excludes rain and prevents leakage, but also prevents the tearing of the roofing material at the joint, which has heretofore so frequently occurred in roofings of this character, where the burlap simply extended beyond the edge of the roofing material without doubling it back and securing it by nails, as above described.

A ready-made roofing in strips consisting of underlying roofing-strip, substantially as dea cement body portion, and an overlying burscribed. lap portion partially embedded thereon said 1 burlap portion being extended on one edge 5 of the strip, then folded back and stitched J to itself to aiford a base for fastening-nails, Witnesses:

and a, flap to cover said nails and to lap over R. J. STAUVERMAN, and be secured on the top of the adjacent JNO. E. BREESE.
