Description
UNITED STATES DORWIN 1). PENNOYER, 0F BOSTON, Assienon, BY MESNE ASSIGNMENT PATENT OFFICE.
OF ONE-HALF OF HIS RIGHT TO JESSE S. WILLIAMS, OF LOWELL,
MASSACHUSETTS.
COMPOSITION i FOR RooF's.
SPECIFICATION forming part of Letters Patent No. 224,606, datedFebruary 17, 1880.
Application filed Oetobei 3, 1879. i
To all whom it may concern.-
Beit known that I,DoRw11v D. PENNOYER, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Composition for Roofs and Walls of Buildings, Ships Bottoms, &c.; and I hereby declare the followingto be a full, clear, and exact description thereof.
Heretofore it has been customary to coat roofs with a preparation of coal-tar pitch, and afterward spread over it a layer of gravel to make it water-tight; but this method is objectionable for the reason that when the roof be- 1 i comes heated by the rays of the sun the pitch.
blisters or boils and runs, leaving the roof bare in some places and in a leakycondition, and almost impossible to repair and make tight Without removing the entire covering.
My invention has for its object to overcome this difliculty; andit consists in a compound formed of certain ingredients combined and treated in such a manner as toproduce an elastic covering for roofs, 85c which is capaabout five gallons of coal-tar and five gallons of raw tar (raw tar being the trade designation of Stockholm tar in a raw state) and ble of successfully resisting the action of heat and water.
I take a suitable vessel and place therein set it over a fire,and when hot add five pounds of ground rock-salt and ten pounds of flour of lime, and thoroughly incorporate the whole togetherby stirring. After the masshas become nearly cool I add four pounds of mu-- over it, which adheres tenaciously to the compound and forms a cement covering which will effectually exclude water.
My improved composition will effectually exclude water when applied directly to the surface of the shingles or boards composing the roof or wall of a building without the addition of sand or fine gravel, and it may also be applied to ships bottoms with advantage,
as. the muriatic acid contained in thecompound will prevent barnacles from adhering 'muriatic acid destroys all the inflammable qualities in the tars, and renders the composition fire-proof.
In ordinary temperatures the composition is sufficiently liquid to allow of its being readily applied, while in cold weather it would be necessary to slightly heat it before using.
My improved compound adheres very tenaciously to any surface to which it is applied; is light, cheap, and durable, and perfectly tire and water proof; retains its elasticity, and will not run or melt by heat. Furthermore, it improves by age and wears smooth.
If the roof should accidentally beceme broken, it can be easily and cheaply repaired and rendered perfectly tight, which is not the case where rooting compositions as heretofore made are employed.
I am aware that muriatic acid has heretofore been added to paving compounds containing coal-tar or asphaltum; hence I make no broad claim to the addition of said acid to such compounds.
What I claim as my invention, and desire to secure by Letters Patent, is
The within-described composition for roofs. &c., consisting of coal-tar, raw tar, ground rock-salt, flour of lime, and muriatic acid mixed together in about the proportions named, and used With or without sand or gravel, substantially as and for the purpose set forth.
Witness my hand this 29th day of Septemher, A. D. 1879.
DORWIN D. PENNOYER. In presence of W. J. CAMBRIDGE, GHAs. E. GRIFFIN.
