ROOFING Application March 25,

' Claims.

My invention relates to roofing, and includes among its objects and advantages, the development of a simplified lock-shingle improved as to appearance, coverage and ease in shippin and 5 laying.

In the accompanying drawings, Fig. 1 is a plan view of a small portion of a roof according to the invention.

Fig. 2 is a diagram of an assembly of the shingles of Fig. 1 to completely cover a continuous area without overlap.

Fig. 3 is a plan view of another small section of root according to the-invention, and

Fig. 4 is a. diagram indicating how shingles according to Fig. 3 may be cut from a strip oi roofing without waste.

In the embodiment oi! the invention selected for illustration, each shingle comprises a generally hexagonal body 10 provided with short end stubs 12 and 14 extending in alignment with each other from opposite apexes of the hexagon. A slit at 16 in the side of the lower stub 12 completes the cutting of the shingle. Upon reference to Fig. 1, it will-be noted that the shingles can be as laid with the stub 12, or butt, of each shingle interlocked as at 18 with the vertical side of the body of a shingle in the next lower course of shingles. This permits the person laying the shingle to vary the vertical spacing or head lap,-

and the horizontal spacing, each independent 0! the other, to produce roofs of different character, depending on the conditions of service encountered. Thus by decreasing the lateral spacing sufficiently to let each shingle of Fig. 1v lap over laterally on the shingle to its left, and decreasing slightly the vertical spacing between successive courses, a roof can be laid such that no portion of the surface of the roof is covered by less than two thicknesses of material. Similarly, while the spacing indicated in Fig. 1 'is an advantageous one for most conditions oi service, the vertical spacing could be materially increased and the horizontal spacing substantially increased to increase the coverage at the expense of the i amount of overlap between the shingles. Such an increase in coverage might readily be practicable i n climates where severe weather and high winds are rare.

It is possible to position shingles according to Fig. 1, so that they will completely cover an extended area with no overlap between the shingles. This is indicated in Fig. 2. However, no area that can be developed in this way has any straight side or end, so that shingles according to 1929. Serial No. 349,570

Fig. 1 could not be cut from a strip of constant width without waste.

By changing one line of severance in the diagram of Fig. 2 from the position indicated at 20 to the dotted line position indicated at 22, this 50 line of severance can be aligned with adjacent sides of the hexagons defining the main bodies of the shingles.

The cutting diagram of Fig. 4 results from this change. It will be noted that the axis oi! the 55 shingle lies at an angle of 45. to the axis of the strip, that all the butts 12 are positioned in the middle of the strip, and that all the stubs 14 lie along the outer edges of the strip and are no longer square ended, but cut to form an oflset point. Shingles out according to Fig. 4 may be laid to form a roof according to Fig. 3. Upon comparing Fig. 1 with Fig. 3, it will be evident that except for the transfer of one corner of the butt 14 to form the tip-.01 the offset point 15 at the top of the shingle, this roof is identical with that of Fig. 1. Furthermore, the portion transferred is completely covered by other shingles and the transfer has no deleterious effect on the character of the finished root. The shingles may be attached to the supporting structure in the usual way by nails 33.

The shingle according to Figs. 8 and 4, however, has several advantages over that of Fig. 1. The first and most important advantage is that it may be cut entirely without waste of material. Another is that packages shaped to conform to the offset configuration will result in stacking all the shingles with their interlocking slits 16 in corresponding positions. Another advantage is that the person laying the root need not inspect a shingle to find a slit, as the irregular configuration of the top tells him instantly where the slit must be. With the shingle of Fig. 1, it

would in many instances be necessary to look as closely at one stub and then turn the shingle end for end to bring the slit in the right position.

Another material advantage will be apparent upon reference to Fig. 4, in which I have indicated in dotted lines at 26, on two of the shingles, the areas that will be exposed in the finished roof. It will be noted that a fairly wide area at the edge of the strip portion shown will all be covered in the finished roof, and that the butts are all in a narrow zone close to the center line of the strip portion.

By varying the character of the coating transversely of the strip it is possible, on account of this arrangement, to have difierent portions of the cut shingles covered with difierent grades or 11g material to adapt them for the difierent condi-' tions of exposure in the finished root. Thus I have indicated in Fig. 4 a bare belt 2'? at either edge of the strip. These areas may be left entirely without grits, and in the finished roof they will have a tendency to stick to the under side of the shingles overlying them and cement the finished roof after a few summers into a one piece sheet. A second belt 28 nearer the axis may receive a relatively light or low grade coating of grits. A third zone 30 may receive a. standard service grade of material and the central zone 32, from which all the butts will be formed, may be given an extra heavy coating, not only of grits but of asphaltum also, if desired.

Without further elaboration, the foregoing will so fully emlain the gist 01 my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions and service.

What I claim is:

l. A shingle comprising a generally hexagonal body with stubs projecting from two opposite apexesof the hexagon, one stub being slitted at one side to interlock with the'side of another shingle, and the other stub being beveled to an offset point, the slit and point having predetermined relative positions.

2. A roof made up of substantially hexagonal shingles laid with one apex pointing down, each shingle having a square stub at the downwardly pointing apex, each stub having a slit in one side only, the shingles of one course-being laid with .their adjacent vertical edges slightly spaced to facilitate interlocking the stub with one of said edges, said stubs being each interlocked with the edge Of a shingle in a lower course.

3. A roof made up of substantially hexagonal shingles laid with one apex pointing down, each. shingle having a stub at the downwardly pointing apex, each stub being interlocked with a vertical edge of a shingle in a lower course.

4. A shingle comprising a generally hexagonal body, and a rectangular prolongation iormed integrally therewith and provided with an interlock for adjustable connection with another shingle, said interlock permitting independent vertical or horizontal adjustment,

5. A shingle comprising a generally hexagonal body laid with one apex pointing down, and a stub projecting from the downwardly pointing apex and provided with a horizontal interlock for adjustable connection with another shingle, said interlock permitting independent vertical or horizontal adjustment.
