SHINGLE ROOFING.

Application filed August 11, 1923. Serial No. 656,923.

T 0 all 2072,0712 it may concern:

Be it known that I, JOSEPH F. DONAHUE, a citizen of the United States, residing at South Bend. in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Shingle Roofing, of which the following is a specification.

The invention relates to shingle roofing, and has for. its object to provide a roof formed from a plurality of interlocked shingles wherein the roof after being covered by the shingles, has substantially a double covering of shingles, and at the same time to ac complish this result with a minimum numw ber of shingles.

A further object is to provide a roof formed from a plurality of interlocked shingles laid in horizontal courses, said courses overlapping adjacent courses, and interengage in a manner whereby curling of the shingles will be prevented, and the courses locked together.

A further object is'to provide a shingle roof formed from a plurality of shingles, preferably of the plia le type, which shingles comprise rectangular shaped body por tions having their ends in abutting engagement thereby forming courses of shingles, and V-shaped projections carried by the sides of the bod portions and having their converging si es provided with slots for receiving the adjacent converging sides of shingles in the adjacent course. The shingles are preferably of greater length than width, therefore a minimum amount of overlapping of shingles ofadjacent courses is obtained, and the area of the roof covered by three plies of shingles or portions of shingles is reduced to a minimum, thereby allowing the covering of a roof with two plies of shingles with a minimum number of shingles.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set drawing, described and claimed, it bein understood that changes in the precise em diment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:-

Figure 1 is a top plan view of a section of roofing showing the interen aged shingles.

1 Figure 2 is a plan view 0 one of the shing preventing overlapping,

Figure 3 is a perspective view of adjacent shingles showing the same interengaged.

Referring to the drawing, the numeral 1 designates a portion of a roof formed from a plurality of shingles 2. The shingles 2 comprise rectangular shaped body portions 3, which-are preferably oblong shaped, and V.-shaped extensions 4 extending from one of the sides, thereof, and having their converging sides 5 spaced from the ends 6 of. the body portion, thereby forming shoulders 7. The shingles are preferably of greater mum amount of overlapping for securing a roofing comprising two plies of shingles. The outer ends of the extensions 4 are preferably cut ofl as at 8, thereby obviating "points when the roof is formed, which points have a tendency to curl incident to weather and heat, and at the same time are proportioned in relation to the body 3 of the shingles for as will be hereinafter set forth. The shingles 2 are laid in courses horizontally as shown in Figure 1 with their rectangular shaped portions 3 in abutting engagement, and with their extensions 4 extendingin the same direction, and in vertical relation to the roof. The shingles of each course may be nailed in position if so desired during the laying of the roof. The roof is preferably laid in courses from the top downwardly. After the upper course has been laid, the next course is placed in position beneath the upper course, by placing the body portions 3 of the next course beneath the projections 4 of the course above, thereby underlapping or underlying the body portions of the shingles of the course above, at which time the opposite converging edges 5 of the'shiugles of the course being laid are placed. in inwardly extending slits 9 of they projections 4 of the course previously laid, thereby interlocking the shingles of each course with the shingles of adjacent courses at points between the projections 4. The shoulders 7 prevent downward movement of the shingles and consequently each course is interlocked and held against diplacement in relation to each other. It will be noted that the projections 4' of adjacent courses are in staggered-relation, thereby providing a symmetrical outline and an artistic appearancefor the roof. 4 The shingles are proportioned whereby a minimum amount of overlapping is provided, and at the same time proporlength than width, thereby allowing a minionly tio-ned whereby when the'shingles are 551 tioned on a roof-a double ply of shingles will cover the entire roof, which is suflicient for all practical purposes, thereby reducing the number of shmglesneeessary for covering a roof; to a minimum, and reducing the three 'pointsto a minimum for instance the three ply points are formed by the -V- ed" portions 10 adjacent the slots I 9,

shap

which portions are relatively small in area The cutaway. ends 8 of the projections l, when tl'ie'roof is formed register with the outer sides 11 of the rectangular shaped portions 3 of shingles below the shingles, the particular portion, 4 overlies, thereby obviating three ply roofing at the lower ends of the projections. Although the forming of *the roof has been described as starting at the upwardly top of a roof and working downwardly, it is obvious that this operation may be reversed, and the roof laid from the bottom or eaves to the ridge of the-roof.

From the above it will be seen that a roof isprovided which is formed from a plurality of substantially T-shaped shingles, laid in horizontal courses and the shingles of adjacent courses in staggered relation'and in,

"terlocked, and that theshingles are proporjections carried by the lower side of each of the. body portions,

said projections being spaced-from opposite sides of the body portions, thereby forming shoulders in horizontal alinement with each other, said projections having their sides converging-towards their ends and provided with slits intermedi- 5 ate their ends, -said projections interengaging with adjacent diverging sides of adjacent iangularly disposed projections, the.

shoulders formed by the angul'arly disposed projections forming means cooperating with the slits for preventing movement of the shingles and maintaining the same in horizontal courses. 1

In testimony whereof I afiix my signature.
