To all whom itmwy concern:

Be it known that I, ARTHUR SIEBEL, a sub- 3 ect. of the King of Prussia, residing at Dusseldorf,in theKingdomofPrussia,Germany,have invented an Improved Roofing and Isolating Material, (for which Letters Patent have been.

granted in Germany April 19, 1888, No. 45,509;

in Belgium June 24, 188,9, No. 86,751; in

ground, 850., while, on the other hand, the metal imparts to the compound material com- 'plete impermeability. I

In the annexed drawings, Figure 1 shows the said .material-in/seetion, a being the metallic core, and b b two protective layers. Fig. 25s} sectionalview representing a mode of uniting two pieces of the material.

. For "the metallic. base or core I prefer to use lead on account of its property of being easily bent and of retaining the shape imparted to it, and also because it is particularly resistant to chemical action.

The substances from which I form the said protective layers consist in asphalt orpr'eparations thereof, tar,whether crude or prepared for tarring roofs and walls, and other hydrocarbons adapted to become suificiently hard; moreover, pitch, rosin, ozocerite, refuse of stearlne-works, and bituminous schist or any mixtures thereof. Such of these substances or mixtures as have in themselves body enough may be employed alone. In the contrary case I add thereto fibers of asbestos, powdered minerals, hairs, caseine, sand, saw- .edust, or mixtures of the same capable of forming a plastic mass with the former. The layers, after having been brought onto the metal, are un ted therewith by pressure. 0n the outside these layers may be strewn over with;

powdered minerals or covered withv a fabric or with like. Such fabrics, paper, pasteboard, or felt may, however, also be incorporated into the body of the said layers.

paper impregnated withtar or the x If tar or any substitute' or preparation thereof is employed, an advantageous mode of proceeding is to impregnate sheets of pasteboard or feltlike fab rics of vegetable or animal fibers or asbestus with the tar, to apply them to one or both sides of the metal and to unite them therewith by pressing or rolling, or a number of sheets of paper or any suitable fabric are thus impregnated andlaid one ip'on the other and pressed on the metal. "Tn some cases I cover the layers with metal "foil, or I coat them with metal'by galvano-plastic means/ The described material possesses various qualities which render it valuable for building purposes' It is capable of being bent so that it may be brought into various forms, while it possesses the requisite stifiness to retain such forms. It may thus, for instance, be employed for making gutters therefrom. If used as isolating material, it has the superiority of being absolutely impermeable to moisture, If applied to roofs, it unites the advantages of asphalt roofing with those of metal roofings, while its durability and its impermeability are greater and its weight is less. It may also beformed or divided into plates adapted to be used as roofing-tiles.

In view of obtaining aiperfect union of juxtaposed sheets or plates at their edges, an advantageous mode of proceeding is as follows: During the manufacture of the sheets or plates the edges of the protecting-layers are prevented from uniting with the metalhering edges of the protecting-layers are bent off a little from the .metal, a suitable cement is laid on the surfacesthereby exposed, (either with or without removal of the strips of paper,) and the sheets or plates are pushed together with their open opposite edges, so that the metal of the one bears on that of the other, and the protecting-layers When such sheets or overlap each other, as shown by Fig. 2. Finally the sheets or plates are firmly united by pressure along the line of junction. A very tight sixfold joint is thus obtained.

I claim as my invention A pliable roofing andisolating material for building purposes, consisting of metallic foil or thin sheet-lead having united thereto on both sides a protective layer composed of a to fabric such as paper or felt impregnated with tar, asphalt, pitch, or the like, substantially as and for the purposes'hereinbefore set forth.

. In testimony whereof have I hereunto set my hand in the presence of two subscribing wit- 1 5 nesses.
