Application filed October 1, 1915. Seria11\To. 53,520.

To all whom t may concern:

Be it known that I, ANTON L. V. NiLssoN, a citizen of the United States, residing at Tularosa, in the county of Gtero and State of New Mexico, have invented certain new and useful Improvements in Concrete Shingles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in roof shingles and more particularly to those constructed of cement or other plastic material.

It is a well known fact that the ordinary shingle constructed of cement or other hardened plastic material frequently cracks when being applied to the roof of a building.

My invention is designed to overcome this objection by providing plugs ofyieldable material which are molded in the shingle during its constructiomthese plugs being designed to have the fastening elements driven therethrough when laying the shingles.

rIhe construction of my improved shingle will hereinafter be more particularly described and claimed and shown in the drawings wherein:

Figure l represent a perspective View of a cement shingle embodying my improved features of construction; Fig. 2 is a transverse section on the line 2--2 of Fig. I; Fig. 3 is a detail perspective view of one of the yieldable plugs removed from the shingle; Fig. l is a vertical sectional view of a slightly modified form of plug'.

I preferably mold these improved shingles in the form of the ordinary wooden shingles now commonly in use, the outer end l of the shingle being considerably thicker than the inner end 2 which is covered by the upper course of shingles. These shingles may be constructed of any preferred form of plastic material such as Portland or plaster cement.

My improvement consists in placing the plugs 3 within the body portion of the shingle, preferably in the upper end 2 thereof. One or more of the plugs 3 may be molded in the shingle during the course of its construction, the number depending upon the number of fastening elements required for holding it to the roof. Each of these plugs 3 comprises a pair of substantially square heads 4 connected by a contracted neck 5, thus providing a central portion smaller in size than the heads 1l. This arrangement prevents the plugs 3 from becoming dislodged from their cavities and becoming lost.

It is obvious that these plugs must be formed of any yieldable material, which will readily compress when the nails are driven therethrough, rubber being .the preferred form of material although similar substances could be employed to equal advantage.

From the foregoing description it will be obvious that I have provided a shingle which .can be readily nailed to the roof of a buildmg without any danger of its cracking, as is the case with the ordinary cement or concrete shingles now in use.

1While I have described the form of shingle best adapted for the covering of ordinary buildings, it is obvious that various changes in such form as well as changes in the size and shape of the plugs may be resorted to within the scope of the appended claim without departing from or sacrificing any of the principles of the invention.

I claim:

A. rigid roofing shingle of imperishable but frangible material having near its upper end an aperture which opens through its upper and lower faces, said aperture being enlarged at its upper end, and a resilient nail receiving plug snugly received in said aperture and lying flush with the upper face of the shingle, said plug being in yieldable contact with the wall of the aperture, whereby if after securing the shingle in place it should become necessary to pry it from the roof, said plug will contract and pull through the aperture, leaving the shingle intact for further use.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ANTON L. V. NILSSON.
