UN@ STTS ROOFING SEINGLE. A

Application filed February 2, 1921.

T o all whom t may concern:

Be it known that I, JOSEPH F; WEBER, a citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented certain new and useful Improvements in Roofing Shingles, of which the following is a specification.

This invention relates to shingles such as employed for roofing, sheathing, and other purposes in the construction of buildings.

l/Vith shingles as now manufactured and applied to buildings', the thick ends of shingles of each course form with the adjacent upper surface of the underlying course a lodgment for accumulations of dirt, leaves or other material.

Such accumulated material serves to retain moisture against the shingle butts and cause rain-water to back into the interstices between the shingle courses to produce a roof which is diiicult to keep dry thereby hastening the decay of the shingles. 'For similar reasons the conventional form of shingles is objectionable for painted work, either roofing or siding, inasmuch as the paint applied thereto produces the so called paint-dams at the butt ends of the various courses.

Thepurpose of the present invention is to overcome the above mentioned and other objectionable features inherent to shingles having thick extremities by the provision of shingles of peculiar forms which will obviate the collection of dirt, be more du-rable and, generally, furnish a more serviceable roofing or siding for buildings.

The invention consists inthe novel features hereinafter described and claimed.

In the accompanying drawings,-

'Figure l is a plan viewof a shingle embodying my invention. Fig. 2 is a side edge view of the same. Fig. 3 is a perspective view of a portion of a roof structure in which my improved shingles are employed.

A shingle 5 is made of an oblong rectangui lar shape in plan, as shown in Fig. 1, and is tapered toward its point end 6 in the usual manner.

In the present invention, the top of the Serial No. 441,752.

shingle is beveled for a distance of approximately one inch from its butt end 7. The bevel surface 8 thus produced makes an obtuse angle 9 with the upper surface l0 of the shingle and is arranged to terminate at the adjacent end to afford a thin butt at 7.

Said bevel surface is formed concave to facilitate manufacture but, more especially, to allow water to run o more freely than with other forms.

By reason of the shingle having its maxi,-

mum thickness below the angle 9 and thencey tapering it to the butt' 7 a shingle may be laid with more projection, or weather exposure, than hitherto with less liability of bending or curling.

In applying my improved shingles, the lirst course A, Fig. 3, is laid double with the lower tier thereof inverted to have the bevel of the same underneath thereby providing an advantageous support for the butt ends of thesuperposed tier of shingles where the same are to extend beyond the ing shingle formed adjacent to ,its butt end with a concave surface disposed in angular relation to the planes` of the bottom and top surfaces of the shingle and affordin a thin butt extremity in a plane substantialy at right angles to said bottom surface a maximum thickness of the shingle at a short distance from such extremity.

Signed at Seattle Washington, this 28th day of January 1921.

JOSEPH F. WEBER.
