SHINGLE I Filed 001:. 26, 1938 Attorneys Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a shingle of the flexible type, the general object of the invention being to provide interlocking means between the shingles of a row and to make that side edge of each shingle, which is exposed, slope upwardly and outwardly and to provide said edge with numerous projections so that said edge will cause the water to pass from the shingle upon the next shingle in such a manner that very little of the water will pass over the interlocking parts, thus increasing the life of the locking parts.

Another object of the invention is to so form the shingle that a plurality of the shingles can be cut from a length of material with practically no waste of material.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing theinvention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a face view of the improved shingle.

Figure 2 is a fragmentary view showing how the -shingles are placed together in rows on a roof or the like.

As will be understood these shingles are to be formed of any suitable type of roofing paper and each shingle A has the sloping side edges i and 2, the edge I, which is the exposed edge when the shingles are put in place, as shown in Figure 2, slopes upwardly and outwardly and each of the edges I and 2 are formed with what might be termed the saw teeth 3.

An extension 4 is formed on the edge I at the bottom of the shingle and a curved tongue 5 is formed on the upper edge of the inner portion of said extension, this tongue leaving a downwardly and inwardly turned curved slot 6 between curved outer wall 8' at the edge 2 of the next shingle though the slot 8 and its hole I must be formed by cutting out parts of the material.

Also, to separate the tongue 8.from the lower portion of the shingle a slot 9 is formed between the tongue and said part of the shingle and in the formation of this slot 8 a small tongue III is left leaves an upwardly and inwardly sloping edge I! for the space Thus the edge the edge 2 with can be formed tically no loss Part cut out to As shown in I with the extension 4 will match the tongue 8 so that the shingles of a length of material with pracof material excepting the small form the slot 8 and the hole 1.

v Figure 2, the shingles in each row are overlapped and they are nailed to the member to be covered by nails passing through holes [3 in the tongues 8, though it will, of course, be understood that these holes need not be made in the tongues as of course the nails can be driven through the tongues without the tongues being previously formed with the holes. After the tongue 8 of one shingle is nailed another shingle has its extension 4 placed under the part having the edge II of said nailed shingle with the slot 6 interengaging with the slot 9, the second shingle being placed at an angle to permit this engagement of the parts and then the second shingle is partly rotated to bring the edge I into overlapping relationship with the edge 2 of the first shingle as shown in Figure 2. Then the overlapping portions can be nailed adjacent the top edge as shown at l4 and these nails will be covered by the next row of shingles.

As will be seen each pair of shingles in a row are locked together by what might be termed a double lock as the extension 4 is placed under that part of the lower edge of the second shingle adjacent the edge [2 and the tongue 8 of the second shingle is located under the first shingle and the slots 6 and 9 interlock. The exposed edge I with the specific arrangement of the teeth 3 as shown in Figures 1 and 2 forms a drip edge over which the water will pass from one shingle onto the other and this arrangement will prevent but little of the water flowing over the two shingles from reaching the locking parts so that said parts will have longer life.

It is thought from the foregoing description that the advantages and noval features of the invention will be readily apparent.

into which the tongue 8 extends.

and the outer end of the ex- It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having thus described the invention, what is claimed as new is:

1. A shingle of the class described having an extension at the lower part or one side edge thereof, a tongue extending from the upper edge of said extension and forming a slot between itself and the adJacent part of the shingle, said slot curving inwardly and downwardly and terminating in a hole forming enlargement which is located above the plane of the upper edge or the extension, the other side of the shingle at its lower part having a recess therein, a tongue depending into the recess and forming a slot between its inner edge and the adjacent wall of the recess, said second tonguebeing of considerable length and width so as to receive a nail for fastening the tongue to a root, the lastmentioned slot of one shingle interengaging with and having its upper end wall fitting in the hole forming enlargement of the first-mentioned slot of a second shingle when the two shingles are placed together with the extension of the first shingle extending under a portion 01' the second shingle adjacent the recess, and the second tongue of the second shingle located under a portion of the first shingle.

2. A covering of the class described comprising a plurality of individual shingles, each shingle having an extension at the lower part of one side edge, a small upwardly extending tongue on the upper edge of the extension, the outer end of the extension and the outer edge of said small tongue forming a continuous upwardly and outwardly sloping edge, a large upwardly and inwardly curved tongue on the upper edge of the extension and forming a downwardly and inwardly curved slot between itself and the adjacent part of the shingle, said slot terminating in a hole forming enlargement and the large tongue being spaced from the small tongue and located at the inner end of the extension, the other side edge. of the shingle at its lower part having a recess therein, and a tongue extending into the' recess and said tongue leaving a slot between itself and the adjacent wall of the recess, the cutting of the extension and its two tongues from a strip of material forming a recess with a tongue extending thereinto for another shingle cut from the strip, the tongue which extends into the recess being of a sufficient width and length to receive a nail for fastening the tongue to the part to be covered, said shingles being laid in rows withthe extension of one shingle extending under that part of the next shingle adjacent the recess and a part of the first shingle extending over the tongue of said next shingle with the grooves of the two shingles interengaging with each other to form a lock, that part of the shingle which carries the extension overlapping the adjacent shingle and said overlapping parts having a side edge sloping upwardly and outwardly and having a plurality of teeth therein.
