UNITED STATES PATENT OFFICE.

HENRY M. MINER, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO THE GRANITEROOFING COMPANY, (LIMITED,) OF SAME PLACE.

ROOFING FABRIC.

SPECIFICATION forming part of Letters Patent No.- 278,722,-dated June 5, 1883.

Application filed March 15, 1883. (No model.)

To all whom it may concern Be it known that I, HENRY M. MINER, of Pittsb'urg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in- Roofing Fabric; and I do hereby declare the following to be afull, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view of a web of my improved roofing fabric. Fig. 2 is a crosssection of the same, showing the layers of which it is composed.

My invention consists of an improved roofing fabric, the components of which are compressed firmly together. It is composed, first, of a layer of burlap or similar fabric second, a layer of roofing-paper which is saturated with coal-tar or other similar substance properly reduced; and, third, a layer of sand which is embedded in and adheres to the prepared surface of the paper, the layers being firmly united together and the sand deeply embedded by pressure properly applied thereto. The layer of sand is sufiicient to act as a drier and to cover the whole upper surface of the paper, so that the tar is not exposed at all, thus rendering the fabric easy to handle, and prevent ing all liability to stick or adhere to other ob- The layer of burlap is united to the layer of paper by adhesion.

In the drawings, a indicates the layer of burlap -b, the layer of tarred paper, and c the layer of sand. The upper surface of the sand is preferably of a coarse or large grain. I prefer to use a ground or crushed conglomerate stone, quartz, or granite for the top covering. After the two sheets, webs, or layers a and b are laid together, and the sand applied to the exposed side of the saturated sheet I), the whole is subjected to pressure to unite and compress the sheets, and to embed deeply and intimately the sand, so that it shall give a close, dry sur face, and will not rub or scale off in handling, coiling, or using.

The compressed fabric thus produced is compact, strong, light, flexible,,clean, and easy to handle, indestructible by decay, not liable to take fire, and especially adapted for roofing or sheathing purposes, and particularly for carroofs. 1

Vhat I claim as my invention, and desire to secure by Letters Patent, is

A roofing or sheathing fabric composed of a layer of tarred roofing-paper having an external layer of burlap or other fabric on one side and an external dry coating of sand on the other, compressed together, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 9th day of March, A. D. 1883.

HENRY M. MINER.
