COMPOSITE SHINE-LE.

Application filed December 22, 1922. Serial No. 608,418.

To all whom it may concern:

Be it known that I, VINCENT F. LAKE, a citizen of the United States, residing at Demarest, in the county of Bergen and State of New Jersey, have. invented a certain new and usefullmprovement in Composite Shingles, of which the following is a specificationL This invention relates to improvements n prepared roofing shingles intended to be laid upon a roof in overlapping courses.

The objects of the invention are to provide slate veneer shingles having the desirable properties of prepared roofing shingles, such as waterproof quality, durability, portability, and ease in handling and laying, which shingles, when laid, will simulate the appearance of a ,roof composed of slate shinglee but with a considerable economy both in cost and in weight over slate shingles.

In the accompanying drawings illustrating the invention:

Figure 1 is a perspective view of a shingle embodying the invention, having a corner of the slate facing broken away;

Figure 2 is a view in vertical section, on an enlarged scale, of a fragment of. the shingle;

Figure 3 is a plan view of a modification; and,

Figure 4 is a plan view of another modification.

My invention comprehends the provision of a shingle having a very thin facing-layer 1 of slate secured by adhesion to a body layer 2 of suitable binding material.

In carrying out my invention, I emplo facings of slate veneer which may be ob tained by splitting a block of slate into very thin slabs by means of a suitable slate-splitting machine, or otherwise.

The foundation or backing layer 2 consists of adhesive waterproof binding material, such as asphalt or other bituminous substance. used either alone or in combination with a base of fibrous material. I preferto use a backing of prepared roofing material consisting of a piece of roofing felt (a) saturated with bituminous composition and having a coating (in of bituminous composition on one or'both of its surfaces. The coating material (6) coheres with the saturated felt and in itself presents an adhesive surface to which the slate facing 1 is applied and adhesively fastened, thereby forming a unitary structure.

In Figure 1 of the drawings 1 have illustrated a shingl in which the facing 1 covers the entire upper surface of the body, while in Figures 3 and 4 are shown modifications wherein the facing covers less than the entire area of said surface. In the moditied shingle illustrated in Fig. 3 only that portion of the surface which is intended to be exposed when laid is covered with the facing. while in the modification shown in Figr. t the facing covers a greater extent of the surface so as to provide a slate veneer lap under the overlapping ends of the shin gles of succeeding courses.

What I claim is:

i. A composite shingle comprising a backing of adhesive binding material and a facing of slate veneer.

2. A composite shin ale comprising a fibrous base having a coating of bituminous composition and a slate veneer facing.

23. A composite shingle comprising a body of fibrous material saturated and coated with bituminous compositions and having; a facing" of slate veneer on its upper surface covering less than the entire area of said surface.

VINCENT F. TAKE.
