ALBERT .AIBBE GRISWOLD, OF PROVIDENCE, RHODE ISLAND, ASSIG FLEXIBLE SHINGLE.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed July 19, 1919. Serial No. 311,912.

To (I?! 107107)! if may concern Be it known that I, ALBERT Anna 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 in the flexible shingles shown and claimed in my United States Patent No. 1,274,410, August 6, 1918.

In the construction of roots and the like on which flexible shingles are used, it is necessary to hold down the tree or lower 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 tree end of the shingle is provided with improved means for securing the same in place on a roof or the like, without forming the free end of the shingle into an under flap, for this purpose, thereby reducing the cost and improving the appearance of the roof.

A further object of my invention is to provide a flexible shingle with a fastening member in the form of a cross-bar secured to the underside of the shingle without penetrating through the shingle.

My invention consists in the peculiar and novel construction of a flexible shingle, said flexible shingle having a lower corner provided with improved means, secured to the underside without penetrating through the shingle for holding down the lower corner and having details of construction, as will be more fully set forth hereinafter and claimed.

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

Fig. 2 is a full size plan view of the lower end of my improved flexible shingle showing the greater portion of the shingle broken away.

Fig. 3 is an inverted plan view similar to Fig. 2 showing an underside improved flexible shingle.

F g. 4 IS an end view of Fig. 2. 1* 1g. 5 1s a transverse sectional view through the shingle taken on line 5.5 of

Fig. 2, and

Fig. 6 is a longitudinal sectional view taken on line 6.6 of Fig. 2.

In the drawing 6 indicates the sheathing ot a roof and .7 my improved flexible shingles. The sheathing 6 may also represent the sheathing on building.

The flexible shin les 7.7 may be constructed of paper, to t and asphalt or other flexible composition or fibrous material, and are preferably square, with two oppositely (llsposed side edges 8.8, one corner 9 being used as the outer or lower corner of the shingle. A fastening member 10 having a flat body 11 with pointed prongs 12.12 and a narrow neck 13 on which is a flat crossbar 14 is secured to the underside of the lower corner 9 by forcing the pointed prongs 12.12 into the body ofthe shingle, without penetrating through the shingle, and in a position for the narrow neck 13 to extend back from the corner of the shingle and for the cross-bar 14 to extend out sidewise across of the corner of the shingle and away from the back of the shingle, the thickness of a shingle, as shown in Figs. 3, 4 and 5. The fastening member 10 also has

side arms

15,15 which clamp on to the edges of the shingle to more firmly secure the fastening member to the shingle, as shown in Figs. 2 and 4.

In shingling a roof or the like with my improved flexible shingles 7.7, the shingles are laid diagonally. Each course is laid by placing a shingle of the next upper course over two shingles on the next lower course in a position for the cross-bar 14 to go under the angular lower edges of two adjacent lower shingles and for the thin neck 13 to pass between the edges of the side edges 88. The shingle is then moved upward until the angular edges of the shingle are on a'line with the adjacent angular edges of the shingle in the lower course, thereby looking the lower corner of the shingle being laid to two shingles previously laid. The shingle is now secured in place by nails 16.16 through the side edges 8.8 as shown in the outer walls of a view of my Fig. 1, and the same operation repeated for the next shingle.

In my improved flexible shingle, the" under flap as shown in my patent referred to is eliminated, thereby saving in expense. The means on the lower corner of the shingle for holding down and securing the corner in lace does not penetrate through the shingle. t forms a part of the shingle and is sold with it, and the only operation required for securing the lower corner of the shingle 15 the mere act of placing the shingle in place for nailing the shingle to the roof, and as the under-flap is now eliminated, the shingles when laid, give a true square or diamondv effect to the roof.

I do not wish to confine myself to the construction of the fastening member as this could be constructed in various ways within the scope of the appended claims.

- Having thus described my invention, I

' claim as new bers bei members being "clenched to the underside of the lower corner without penetrating through the shingle, for the purpose as described.

through the shingle, for the purpose as described.

4. A shingle adapted to be laid diagonally and having oppositely disposed parallel side edges, and a lower corner, a fastening member on the underside of the lower corner and having prongs which penetrate into the body of the shingle to secure the fastening member in place, a neck extending rearward from. the lower corner, across-bar on the neck and extending crosswise of the lower corner and rearward from the lower corner, the thickness of a shingle, and arms on the fastening member which clamp over the edges of the shingle adjacent the lower corner to more positively secure the fastenlng member to the shingle, for the purpose as described. I 5. A shingle according to claim 4 comprislng a fastening member adapted to fasten down the lower corner of a flexible shingle, said fastening member having prongs which penetrate into the flexible material of the shingle to secure the fastening member to the underside of the shingle, a neck and a cross-bar on the neck, for the purpose, as described.

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

ALBERT ABBE GRISWOLD.
