This invention relates to roofing shingles, and more particularly to composition shingles of a flexible character and adapted to be laid in overlapped, interlocking relation on a roof; it being the principal object of the present invention to provide shingles of the above character that may be laid especially fast and easy; which have a very efi ective interlock formed without any undue overlap or waste of material; which do not permit leakage at the joints; and which will lay flatly and tightly together injplaoe on a root.

. More specifically stated, the inventionresides in the provision of shingles of the above character of substantially rectangular form, and designed to be laid in horizontal courses; and wherein each shingle of a course has one side edge underlapping the next adjacent shingle at that side. and has its opposite edge overlapping the edge of the next adjacent shingle at that side; and wherein each shingle is provided near the side edge of the overlapping portion with a slit of novel formation setting 03 an anchor tab from the'bottom edge of the shingle over which will lie the underlapping portion of the adjacent shingle to thus cover the tab. and at the same time, efi'ect an interlock whichwill hold the lapped edges of the two shingles securely in place.

Another object of the present invention is to provide a method of cuttingthe shingles from a strip so as to avoid waste and to thereby provide maximum roof coverage from the strip.

Other objects of the invention reside in the details of construction of the individual shingles and in the method of laying them. as will hereinafter befully described. In accomplishing these and other objects of vtheinvention, l have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Fig. l is a perspective view of a part of a 'rooi formed by shingles cut and laid in accordance with the present invention.

Fig. 2 is a perspective view of one of the n shingles, particularly illustrating the formation and location of the anchor tab defining s it.

Fig. 3 is a sectional detail on the line 33 in Figure l, showing/the overlap of the shingle ends and underlap of the anchor tab.

Fig. 4 is a plan view of a strip of material indicating a method of cutting the shingles from the strip.

Referring more in detail to the drawings- It is the gist of the present invention to 50 provide shingles that are relatively inexpensive; which may be quickly and easily laid in place; and which may be interlocked insuch manner that they will be held flatly against a roof without danger of buckling or of becoming loose; and which may be secured in place by nails, which will be completely covered in the finished roof. The invention also provides shingles having the anchor tabs formed by slits extending into the shingle body from its lower edge as distinguished from those shingles in which the side edges are slit. V c

In carrying out the invention, in its present form, the shingles are all cut of the same size and shape; and preferably would be substantially rectangular and having a width approximately twice its height. The shingles are intended to be laid in horizontal courses wherein each of the shingles has its opposite end portions, respectively, underlapping and overlapping the next adjacent shingles in the course.

As shown best in Figure 2 of the drawings, the shingle 1 has parallel upper and lower edges 2 and 3, and a'square cut end edge 4; at right angles to edges 2 and 3. This square cut end of the shingle will be designated as the overlapping end. The opposite end of the shingle is cut angularly. It has

edge portions

5 and 6 cut straight in at right angles' to the upper and lower edges of the shingle but in offset relation to each other, so that the lower edge portion of the'shingle from edge 4 to cut 6 is longer than the upper edge portion from edge 4 to cut 5. These straight out

portions

5 and 6 are of equal lengths. and at their inner ends are connected by the diagonal edge '7.

Each shingle is provided'in its lower edge mo portion near the overlapped end with an anchor tab 8. This tab is defined or formed b a series of-connected slits, comprising the slit 10 which extends inwardly from the lower edge 3 of the shingle at a right angle thereto, then merges with a slit 11 extending laterally at a right angle toward the opposite end of the shingle. Slit 11 then joins with a shorter slit 12 that turns downwardly toward the lower edge of the shingle; the three slits 1O, 11 and 12 thereby setting ofl an anchoring tab 8 that is free on three sides and may be offset from the body of the shingle to effect the interlock without buckling.

In laying the shingles on a roof, they are laid in horlzontal courses, as shown in Figure 1, preferably by starting at the left hand side and laying toward the right. When a shingle is laid in place, anail, as at 15, is

' driven through the anchor tab. The next adjacent shingle is then laid by projecting its diagonally cut end beneath the square cut edge of the laid shingle to such extent that its lower portion adjacent the edge 6 overlaps the anchor tab of the laid shingle and the square cut end portion 6 abuts against the shingle body along theslit12. A nail, as at 17, is then driven through the overlapping portions of the shingles near their upper edge. Each successive course overlaps the one next below it, to an extent desired, dependent on whether single or double coverage is desired. Thus it will be observed that the upper edges of the shingles of a course are held in place by nails that are covered by the next following course, and the lower edges of the shingles are all held in place by nails through the anchor tabs and these nails are covered by those portions of the shinv gles which overlap the tabs.

By cutting the end edges 6 at a right angle to the bottom edge and by making the slit 12 at a ri ht angle to the edge, the joint between t e shingle end and body along slit 12 is made tight. The slit also permits offsetting of the ta downwardly to permit the overlap and interlock without buckling, or tendency to tear the shingle.

Shingles of this character may be made.

of the usual flexible roofing material and may be provided in various colors so as to make possible a very attractive roof. The interlocking connection described provides for securely anchorin the shingles in place without exposed nai s or anchoring devices.

Quite a saving of material used is made possible by cutting the left hand end of the shingle in the manner illustrated. It is apparent that a certain width of material is required for the lapping of the shingles to cover the tab portions. However, this width is not'require at the upper edge of the shingle, therefore, by cutting on the diagonal line 7 toward the upper edge of the shingle, a cer- 'tain amount of material is saved. When shingles of this character are cut from strips, an advantage of this formation may be taken so as to save approximately one inch of material in each shingle. This amounts to considerable when the shingles are manufactured in large quantities.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is:

1. A roof comprising shingles of substantially rectangular form' laid in horizontal courses; each shingle having its opposite side edge portions, respectively, overlapping and underlapping the edge portions of the next adjacent shingles of the same course, and each shingle being formed near the side edge of its overlapped end portion with a slit extended thereinto from the lower edge and setting off an anchor tab over which the lower edge of thennderlapped shingle is extended.

2. A roof comprising shingles of substantially rectangular form laid in horizontal courses; each shingle having its opposite side edge portions, respectively, overlapping and underlapping the edge portions of the next adjacent shingles of the same course, and each shingle being formed near the side edge of its overlapped end portion with a slit extended thereinto from the lower edge at a right angle, then turned laterally toward the opposite end of the shingle, then directed downwardly, thus setting off an anchor tab that may be offset downwardly from the body of the shingle to receive the lower edge portion of the underlapped end of the adjacent shingle thereover.

3. A roof comprising shingles of substantially rectangular form laid in horizontal courses; each shingle having its opposite side edge ortions, respectively, overlapping and under apping the edge portions of the next adjacent shingles of the same course, and each shingle being formed near the side edge of its overlapped end portion with a slit extended thereinto from the lower edge at a right angle, then turned laterally toward the opposite end of the shingle, then directed downwardly, thus setting off an anchor tab that may be ofiset downwardly from the body of the shingle to receive the lower edge portion of the underlapped end of the adjacent shingle thereover, the edge portion of the shingle along the edge of the downwardly extended portion of the slit serving as an abutment for the edge of the underlapped end of the adjacent shingle.

4. A roof comprising shingles substantial- 1y of rectangular form, laid in horizontal courses; each shingle having its opposite side edge portions, respectively, overlapping and underlapping the edge portions of the next adjacent shingles of the same course, each shingle being formed near the side edge of its overlapped end portion with a slit extended inwardly from its lower edge at a right angle thereto, then laterally toward the opposite end, then downwardly at a right angle to the lower ed e, thus setting off an anchor tab throu h w ich a nail may be driven, and over whic tab the end portion of the adjacent shin le may overlap; said underlapped end 0 the shingle being cut square at its lower edge to fit tightly against the edge of the shingle along the downwardly extended portion of the slit, then inclined upwardly toward the edge of the overlapped shingle.
