UNITED STATES PATENT orr on JUIJIUS RACZ, OF DETROIT, MICHIGAN, ASSIGNOR TO PERFECTION SHINGLE & ROOFING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION i-OF MICHIGAN.

ROOFING COMPOUND.

No Drawing.

To all whom it may concern:

Be it known that I, JULIUs RACZ, a subject of the Emperor of Austria-Hungary, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Roofing Compounds, of which the following is a order to reduce to a minimum any tendency of the same to become brittle, fragile, and readily chipped away or broken by the wear and tear of handling and commercial use.

In order that those skilled in the art to which this invention relates may'produce thesame, the preferred proportions and ingredients of the compound are as' follows: 35 parts Japan drier, 35 parts iron filings, 15 parts ashes, 8 parts charcoal, 10 parts to .20 parts sand.

vThe above substances and materials are mixed in substantially the proportions specified and are then permitted to ripen or de velop until they are thoroughly and eifectively combined. The mixture is then rolled out upon or otherwise applied to a layer or rip of paper'or equivalent material and after going through a drying process the constitutents of the compound not only become united but form with the paper a practically homogeneous product by virtue of Specification of Letters Patent.

Application filed January 15, 1912. Ser'iaI No. 671,221.

the fact that the compound closely adheres to the paper and penetrates the same. This product may be employed in many different ways in building operations, as well as for other purposes, and is light, elastic, nonfrangible, unaffected by changes in weather conditions, iswaterproof and fireproof and cheap as a commercial article. In fact it has been found that the elasticity of the product increases with age.

TheJapan drier serves to firmly unite the Patented Feb.17, 1914..

iron, ashes, and sand, the mixture of these four ingredients producing an elastic and flexible compound; the iron affords a requisite hardness, the sand afltords a body, and the charcoal accelerates the drying of the materials in the manufacturing process.

For making shingles this product aforesaid has been found exceptionally advantageous as compared with slate, and its fire proof qualities render it highly desirable to use in connection with fire-proof building construction.

The paper carrier when combined with the substances and materials recited is so united therewith by the chemical action of the elements of the roduct that said aper cannot be separate from the ingre 'ents mentioned.

Having thus described the invention what is claimed as new is:

A roofing compound consisting of Japan drier 35 parts, iron filings 35 parts, ashes 15 parts, charcoal B parts, and sand 10 to 20 parts, said compound being capable of adhering to and penetrating'paper.

In testimony whereof I aflix my signature in presenceof two witnesses.
