SHINGLE.

Application led. April 9,

This invention relates to strip shingles carrying a plurality of vbutts and lpreferably constructed from roofing feltor material of similar nature covered with a mineralcoating of some finely divided hard substance,

such as stone or slate.

It is an object ot the invention to provide rooting material con'iprising two different strips or shingles cut out in pairs from a roll or sheet ot material crosswise thereof which will, when laid, form a thatched roof 'having a series of undulating edges irregularly arranged.

A further object ofy the invention is to cut each of said two diierent shingles so that the longitudinal edges thereof will all be differently shaped, although the longitudinal edges on one shingle will be complenientarily shaped with the respective longitudmal edges on the second shingle whereby the shingles may be cut out in pairs from a roll or sheet ot' material crosswise thereof withoutl waste. By forming cach longitudinal edge ot the two designs of shingles dlttercntly, various irregular and tortuous lines may be formed in a roof laid with sald shingles and either of the longitudinal edges ot each shingle may be disposed downwardly as desired. In other words, both of the shingles or units are reversible edge for edge.

These and other objects of. the invention will be apparent from the following description made in connection with the accompanying drawings wherein like characters refer to similar parts throughout the several views, and in which y Fig. 1 is a plan view ot' one of the pair ot strips or shingles embodying the invention,

Fig. 2 is a similar View of the other stripv or shingle embodying the invention.

Fig. 3 is a plan view of a portion of a sheet of material cutout to form the pairs of shingles or strips, and

Fig. 4 is a plan view of a' plurality of each of said shingles arranged and laid to cover a roof and present a thatched appearance.

The shingles are preferably constructed from a foundation-sheet of wool felt or other similar material with a coatiner of some selfhardening material, such as pitch or asphalt on one surface thereof and with a. layer of finely divided hard material, such as slate or stone thrust through the coating and embedded therein.

1926 Serial No. 100,855.

In the drawings two different and distinct shingles are shown indicated by the letters A and B respectively, cut in pairs crosswise of a sheet or roll of material. Shingle A illustrated in Fig. v1 has its longitudinal sides 1 and 2 cut on different non-parallel tortuous lines. The ends 3 ot' shingle A are parallel to each other and perpendicular to the longitudinal center line of the shingle.

Shingle or section B (see Fig. 2) has its longitudinal edges cut on non-parallel tortuous lines 4 and 5, t-he edge 4 being complementarily formed with edge 2 of shingle A and the edge 5 ot' shingle B being complementarily formed with edge 1 of shingle A. Thus it will be seen that the combined width of shingles A and B will be equal through all points across the width of the roll from which said shingles are cut.

Fig. 3 illustrates the manner in which the shingles' are cut erosswise from the roll or sheet. Thedotted lines indicate the edges ot the sheet and it will be obvious that there will be only a very small amount of waste in cutting the first shingle from the roll indicated by the cut out corner portions and y respectively. A plurality, shown as three in the drawings, of slots 6 are eut intersecting the complementary edges of a pair of. shingles and parallel with the ends of the sheet or roll. These slots. it will be seen, have their ends aligned at right angles to the longitudinal edges of the roll and they extend at various depths into the separate shingles, thereby forming four butts on each longitudinal edge of each shingle. In shingle A the but-ts on the upper longitudinal edge are numbered 7, 8. 9 and 10, while the butts on the lower longitudinal edge are numbered from left to right 11. 12, 13 and 14. The butts formed on the upper longitudinal edge of shingle B are numbered 15, 16,17 and 18 respectively and the butts on the lower edge are numbered. 19, 20, 21 and 22 respectively. Notched recesses z are cut out from the outer edges of the ends ot each shingle adapted to form slots similar in shape to the slots 6 when two shingles are abutted end for end as shown in Fig. 4. Notched recesses e also torm'nail'ing flanges at the ends of the shingles.

It will be seen that each butt formed on the two shingles is differently shaped from every other butt on the two shingles and will simulate a great Variety of separate shingles 1w or pieces of slate when the roof is laid. Every butt, however, has a complementary shaped butt on the other shingle of the pair.

In laying the shingles upon a roof, parallel horizontally extending lines are usually drawn on the roof on which the nailing ianges atl the ends of the shingles A and may be gauged.- The shingles A and B may be then laid on with the desired longitudinal edge downward, the nailing flanges of one shingle abutting the nailing fianges of another shingle laid along the side thereof. The shingles are preferably broken on the third when the succeeding layers are laid but may of course be broken on the half if desired. However, by breaking on the third it will be 0b vious that every part of the roof is covered with two layers of solid material there above in spite of the slots 6. The beauty of the design obtained by laying the shingles islargely a matter of the skill of the roof layer in quickly picking the proper shingle A or B and turning t-he longitudinal edge downward to obtain -the effect of a series of undulating edges arranged in non-parallel relation and almost coinciding in some points while spaced farther apart at other points. l

It is of course apparent that while curved lines have been shown as forming the longitudinal edges of the separate shingles, the points of the several butts may be connected by straight lines to form irregular and tortuous longitudinal edges all within the scope of this invention. Curved lines, however,

" give a slightly more pleasing appearance.

It is of course understood that I am not.

limited to the use of four butts for eachshintgle or strip, but that a greater or less number may be employed as desired and that various curves or tortuously extending lines may be employed to cut the longitu inal edges of the shingles. It will of course always be necessary, if the shingles are to be cut from a sheet or roll without waste, to have the edges l and 2 of shingle A complementary with the edges 4 and 5 of shingle B.

It will be apparent that the amount of waste in the sheet or roll in cutting my shingles is extremely small, being only the small corner portions left in starting to cut the roll and that left at the end of the roll and the amount cut out for the slots 6 and notched recesses .e forming the several butts.

What is claimed is:

1. Roofing material for thatched roofs comprising two shingle strips cut from a sheet of material forming a four-sided figure having two opposite straight and parallel sides, said strips being cut transversely so that they have their remote sides irregularly curved and substantially parallel and the contiguous sides so cut that the sides of each strip adj acent one end are oppositely curved and said sides adjacent its other end are similarly curved and substantially parallel the opposite-curved sides of each sheet eing nonsymmetrical about any axis located therebetween. l

2. Roofing material for thatched roofs including two shingle strips cut from a sheet of material comprising a four-sided gure with two straight parallel sides, the other pair of opposite sides being curved and substantially parallel and the cut forming the contiguous sides being in the form of an irregular curve so that said contiguous sides are complementa] and the opposite curved sides of each strip are non-symmetrical about any axis located therebetween.

In testimony whereof I aflix my signature.
