A. BLANK. WATER PROOF ANO FIRR PROOF MATERIAL POR ROORING.

NO. 409,096. Patented Aug, 13, 1889.

UNITED STATES PATENT OFFICE.

ALOIS BLANK, OF ST. LOUIS, MISSOURI.

WATER-PROOF AND FIRE-PROOF MATERIAL FOR RO'OFING.

SPECIFICATION forming part of Letters Patent No. 409,096, dated August 13, 1889.

Application led January 23, 1889. Serial No. 297,281. (Specimens.)

city of St. Louis, 'in the State of Missouri,

have invented a certain new and useful Improvementin Tater-Proof an d Fire-Proof Material for Roofing and other Purposes, of which the following' is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to produce a flexible water-proof and practically fire-proof material for roofing, siding, and analogous purposes, the material being composed of asbestus with an intimately-united coating of metal.

Figure I is a view of a sheet exhibiting the various stages of preparation. Fig. II is an enlarged section at Il II, Fig. I.

l is asbestus paper or board of any desired thickness. The asbestus material is iirst treated with a mixture of powdered plumbago or other non-volatile carbonaceous Inatter and volatile liquid. rlhe asbestus may be treat-ed upon one or both sides. The volatile part of the mixture is then evaporated by next deposited by electricity upon the asbestus, the copper taking hold of the grains of plu Inbago, which rest in the interstices of the asbestus, and so becoming closely united with the latter. The material is then immersed in a bath of melted metal, preferably tin, lead, or zinc, or an alloy of any two or more of them. The molten metal is deposited on the copper, and thus a sheet 4 of the molten metal is attached to the asbestus fabric. The material is very iieXible, and is practically a nonconductor of heat and lire-proof.

The preferred manner of preparing the article has been herein described; but I do not confine myself strictly thereto. The process has been described Inore at length in my application filed on the 23d of October, 1888, Serial No. 288,886, where claim is made for the process of manufacture.

It will be understood that no vegetable' fiber admits of the described treatment, because the heat of the molten Inetal would destroy it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The metallized asbestus material composed of a body l of asbestus having its interstices supplied with carbonaceous material, a coat 8 of copper adhering to the ca rbonaceous material and entering the interstices of the asbestus, and an outer sheet or layer/4 of metal overlying the copper 8, substantially as set forth.
