ROOFING-FELT.
SPECIFICATION forming part of Letters Patent No. 282,139, dated July 31, 1883.
Application filed January 29, 1883. (No specimens.)
To all whom it may concern:
Beit known that I, WELCOME WHITE, of
of Massachusetts," haveinvented a new and useful Improvement in Roofing-Felt, of which accompanying drawing, is a speciiication.`
My invention relates to an improved roofing-felt for use in covering roofs of buildings to render them water-tight; and it consists of a felting composed of a sheet or sheets of soft porous roongipaper covered upon one side tus, soapstone, and coaltar thoroughly mixed, and of such -a consistency as to saturate the paper, applied thereto while hot, and having a second thin coating of dry powdered asbestus andsoapstone dusted or sprinkled thereon,
scribed.
The accompanying drawing, forming a part of this speciiication, represents a section of a piece of my improved roofing-felt, in which c is a piece of thick, soft, and porous roofingpaper. bis a thin coating of a composition of asbestus, soapstone, and coal-tar, thorough-` ly mixedfand applied while hot, said Vcomposition being substantially the same as that described in another application of even date herewith; and c is a secondary coating of asbestus and soapstone, powdered and thoroughly mixed and sprinkled or dusted thereon in a dry state.
applied as above described, the whole is passed between pressure-rolls to compact or solidify and level the coating.
After the -dry coating is This felt may be applied to roofs in the usual way by lapping one sheet over another and nailing,
in substantially the same way as shingles are laid, and make a water-tight and ire-proof 4o roofing; or it may be used in combination with an outer coating of my improved composition, or of other roofing cements or compositions, applied thereto after it has been secured in position on the roof. The complete saturation of the paper in coating it with the semi-liquid or plastic composition renders it water-proof, and
therefore proof against swelling and shrinking, thus obviating all danger of cracking after the roofing is completed, which is a very great advantage, as heretofore the cracking of the roofing occasioned by the swelling and shrinking ofthe paper which formed the foundation of all plastic rooiing has been the great obstaole to the success of such roofings.
' What I claim as new, and desire to secure byLetters Patent of the United States, is
A roofing-felt composed of a sheet of soft porous paper saturated and coated upon one side with a composition of asbestus, soapstone, and coal-tar, applied while hot7` and compacted and leveled by pressure, substan. tially Vas described. Y Intestimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 27th day of .Iannary, A. D. 1888.
WELCOME WHITE.
