SHINGLE Filed Aug. 5, 1951 MIU@ nhl-OY i@ l Adum Hu'm n Y) pibe/rma W 12% J )3 MM @ciama Cab Patented Aug. 1, 1933 UNITED STATES PATENT OFFICE I A SHINGLEl y Adam F. Martin, Saginaw, Mich. y Application August 5, 1931. Serial No.` 555,157

' 7 C1sims.` (C1. 10s- 7) This invention relates generally to a protective covering and moreparticularly to an interlocking type of shingle.

One of the difficulties hitherto experienced in shingles of this character has been the fact that it has been dicult to fasten the shingles to the roof and it is a primary object of the present invention to overcome this diiculty by providing novel means for interlocking the shingles t0- gether and also fastening the shingles to the roof.

Other objects, advantageous and meritorious qualities reside in the special construction, combination and arrangement of the shingles, as more fully hereinafter described and claimed, reference to be had to the accompanying drawing, forming part hereof, wherein:

Fig. 1 is a plan View of a roof or the like having shingles formed in accordance with my invention laid thereon.

Fig. 2 is a perspective view showing the locking between the shingles.

Fig. 3 illustrates the construction of a single shingle.

Similar numerals refer to throughout the several views.

Referring to the drawing, particularly Fig. 3, l0 designates a rectangularly shaped shingle, preferably formed of asbestos composition or the like, this shingle having diagonal slits 11 eX- tending downwardly and inwardly from either side of near the bottom of the shingle and terminating in small circular holes 12 whereby flaps or tabs 13 are formed.

Slightly below the center portion of the shingle L-shaped slits 15 are cut in the shingle and terminate in holes 16. It will be noted that the distance 17, that is, the distance of the vertical portion of the slit l5, is less than the distance 18 which is the distance between the termination of the lower slit 11 and the bottom of the shingle, whereby, when the shingles are interlocked, the corner portions 19 will extend over the naps or tabs 13 and hence tend to prevent their upward movement by stifiening them. This is clearly illustrated in Fig. 2 of the drawing.

Referring to Figs. 1 and 2, the manner of laying the shingles will be apparent. The shingles are laid in the usual manner by starting at the bottom of the roof and proceeding upwardly. As each single is laid, its bottom edge 21, see Fig. 2, is slid into the L-shaped slit 15, the middle portion of the shingle extending over the upper side of the portion 22 formed by said slit 15. As previously pointed out, this causes the portion 19 similar parts above the slit 15 to extend downwardly over the bottom portion of the shingle 10 which is being placed upon thereof and thus the lower edge 21 thereof is held tightly against the shingles underneath. The flaps or tabs 13 extend under adjacent shingles, see Figs. l and 2, hence maintaining the bottom edge in taut relationship and also prevent leakage from occurring through the joint. The bottom edge 21 of the shingle 10 rests in the holes 16 and thus prevents any tearing of the shingle 10 from occurring.

The shingle 10 which is being laid, as just recited, has flaps 13 extending underneath the shingle at the side thereof and nails 23 pass through these shingles and hold them attached to the roof.

The nails 23 which serve the aforesaid function are shown in the upper part of Fig. 2, these nails being omitted from the locking joints shown at the bottom portion thereof for the sake of clearness. It is to be noted, however, that these nails are driven through the portions 22 as the shingles are applied, there being two nails to each shingle, and the nails passing through two thicknesses of shingle whereby four nails cooperate with the shingle to hold it attached to the roof.

From the above description it will be appreciated that I have inventively created a shingle which is readily formed from a rectangular piece of asbestos sheeting or the like, such being economical as obviously there is no waste when such a shingle is cut from a roll of material. Furthermore, my shingles are easily and quickly laid upon a roof as there are only two nails driven through each shingle and the interlocking attachment between the several shingles are readily laid, the shingle which is being laid being slid downwardly into place and then fastened by nailing to the portion 22 as previously described.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

1. 1n combination, a roofing shingle, adapted to be laid with others in overlapping interlocking interlocking engagement, being of rectangular form, having a slit cut inwardly from each vertical edge at an angle in a downward direction thereby forming tabs at each lower corner, and a 1 horizontal slit cut inward a short distance from each vertical edge midway between the top and bottom longitudinal edges at the termination of each of said slits a vertical slit is cut, thereby forming a tab along each vertical edge, said first mentioned tab in a shingle overlapping and interlocking Awith said second mentioned tab in an adjacent shingle in an assemblage.

2. In combination, a shingle, said shingle having slits out in opposite sides thereof near one end ofthe shingle, said slits' extending towards one end'of the shingle, said shingle also having slits extending inwardly from the sides in which the rst mentioned slits are formed between the rst mentioned slits in theopposite end of the shingle, said second mentioned slits having a portion thereof extending in parallelism with the rst mentioned sides.

3. In combination, a shingle consisting of a at sheet of material of substantially rectangu-y lar shape, said piece of material having diagonal slits extending from opposite sides thereof towards one end thereof, and L-shaped slits extending inwardly and downwardly from. the said sides.

4. A rooting shingle consisting of a rectangular shaped piece of material, said piece of material having diagonalslits extending inwardly from opposite sides thereof towards oneend of the piece of material, and L-shaped slits extending inwardly and downwardly from the said'sdes of the piece of material,` all of said slits terminating in small circular openings for the purposes described.

5. A covering for a roof consisting of a plurality of shingles interlocked together, each of said shingles consisting of a rectangular shaped piece of material having diagonal slits extending from opposite sides of said material near one end thereof, slits extending inwardly from the said sides of the material and then extending in parallelism toward the first mentioned slits, the length of said slits which are in parallelism with the sides of the material being of a lesser distance than the distance between the termination of the first mentioned slits and the end of the shingle.

6. A combination of elements as set forth in claim 5 in which the diagonal slits are adapted to be cooperatively associated with the second mentioned slits of adjacent shingles for the purposes described. 'y

7. A combination of elements as set forth in claim 5 in which the diagonal slitsare adapted to straddle the edges of adjacent shingles of the second mentioned slits in saidadjacent shingles.
