FLEXIBLE SHIN GLE.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed April 25, 1918. Serial No. 230,789.

To all whom it may concern:

Be it known that I. ALBERT Anni: GRIS- won), a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Flexible Shingles, of which the following is a specification.

My invention has reference to an improvement in shingles and more particularly to an improvement inflexible shingles, whereby the shingles are provided with means for securing the outer ends of the shingles in place.

In the construction of roofs and the like on which flexible shingles are used, it is neccessary to hold down the free ends of the shingles so as to prevent bending or curling up of the shingles and allowing rain, snow or sleet to beat up under the shingles, thereby giving an unsightly appearance and causing the roof to leak.

The object of my invention is to improve the construction of a flexible shingle, whereby the outer or free end of the shingle is provided with means for securing the same in place, on a roof or the like.

My invention consists in the peculiar and novel construction of a flexible shingle, said flexible shingle being provided with means for holding down the outer or what has heretofore been the free end of the shingle and having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1, is a plan view of a portion of a flexible shingled roof, said flexible shingles being provided with my improved means for securing the outer or free ends of the shingles in place on the roof.

Fig. 2, is a plan view of my improved flexible shingle.

Fig. 3, is an inverted plan view of my improved flexible shingle.

Fig. 4, is an enlarged detail longitudinal sectional View taken on line 4. 4; of Fig. 3 through the shingle, and a V Fig. 5, is an enlarged detail transverse sectional view taken on line 5. 5 of Fig. 3, through the shingle.

In the drawing 6 indicates the sheathing of a roof and 7. 7 flexible shingles. The roof sheathing 6 may also represent the sheathing in the outer walls of a building.

The flexible shingles 6. 6 may be con- Each shingle 7 has its outer end or corner bent underneath and formed into flap 8 and a preferably flat wire 9 is formed trans-g versely through the flap by forcing one end of the wire in and out through the center portion of the flap. When completed the wire 9 is secured to the flap 8, it lies parallel with the outer or lower edge of the shingle and the ends 10. 10 of the wire extend out beyond the edges of the flap to nearly the side edges of the shingle. The flap 8 is then cemented flat to the shingle or secured to the shingle in any well known way.

In shingling a roof or the like with flexible shingles 6. 6 embodying my invention, the shingles 6. 6 are laid diagonally. Each course is laid by placing a shingle 6 of the next upper course over a shingle 6 of the next lower course in a position for the ends 10. 10 of the wire 9 to go under the edges of two adjacent lower shingles. The shingle is then moved upward and the ends 10. 10 of the wire 9 forced under the adjacent edges of two shingles in the lower course as shown in Fig. 1, thereby firmly securing the lower end of the shingle to two shingles previously nailed to the roof, in the lower course. The shingle is now nailed through its side corners to the roof and the same operation repeated for the next shingle. In my im proved flexible shingle, the means for securing or holding down the outer or free end of the shingle forms a part of, and is sold with the shingle and the only operation required for securing the free or outer end of the shingle, is the mere act of placing the shingle in place for nailing the shingle to the roof. As the act of securing the free or.

outer end of the shingle and putting the shingle in place for nailing is done in one operation, a material saving in time is obtained, and a more perfect roof, at less cost is constructed, than has heretofore been done.

I do not wish to confine myself to the construction shown, as any projecting means on the outer end of the shingle adapted to go under the edges of adjacent shingles, could be used for the same purpose.

Having thus described my invention I clainras new:

1. A flexible shingle having a flap bent edges of adjacent shingles, in shingling aunder the shingle, sidewise extending members on the flap and adapted to go under the roof or the like, for the purpose as described.

2. A flexible shingle having a bent under flap, a member formedpof wire secured to the flap and having outstanding ends adapted to go under the edges of adjacent shingles, previously laid, for the purpose as described.

3. A flexible shingle having a bent under corner flap, a member formed of wire penetrating the flap and having outstanding ends adapted to go under the edges of adjacent shingles previously laid, for the purpose as 15 described.

.4. A flexible shingle adapted to be laid diagonally and having a bent under corner flap, a member formed of-Wire secured to the flap and having outstanding ends adapted 20' to go under-the edges of adjacent shingles previously laid, said flap being cemented flat to the shingle, all for the purpose as described. 1

In testimony whereof, I have signed my 25- name to this specification.

ALBERT ABBE GRISWOLD.
