Application filed Noyein'her This, invention relates to a shingle, the.

. The shin les are cut from a sheet of roofing materia i in such a manner that-they will have a wide rectangular upperportion and'a .somewhat pointed lower portion and-are "cut from the sheet so that there will he very little waste material. The shingles are installed with the narrow end downu'zu'dly and with the rectangular portions spaced a considerable distance apart.

The invention will be understood from the description in-connection' with the accompanying drawings, in which Fig. 1 is aplan view showing the shingles applied to a roof;

Fig. 2 is a plan view showing how the shingles are cut from the-sheet of roofing material. ,1

As shown" in Fi 2 the shingles are cut so as to have a wide upper'portion defined by the lines 1, 2 and 3 and a lower, some-' what pointed portion, defined by the lines 4, 5 and G, and the sheet fromwhich the shingles are cutis so laid out that two reverse] y turned adjacent shingles are cut longitudinally of the sheet and-the pointed portions are adjacent to pointed portions of similar shingles on each side that are cut out in the same manner. In this way rectangular shingles are also cut out at intervals which will serve as the ordinary well known shingles. ()n'eof these rectangular portions is defined 'by the lines 3, 7, 8, 9 and 10. The only waste of material that occurs will be along the edges of the sheet as shown for example, by-the-cut out portion to the right of the line 9 in Fig. 2.

. The shingles are installed upon a roof as shown in Fig. 1 so. that the narrow portions 5 extend downwardly and the edges 1 and 3 of adjacent shinglesare spaced apart a distance" equal to the width of the narrowest portion or the length of the line 5. The narrowest? portion of the shingle may for 1 ,1824. Serial No. 747,805.

but well known to those skilled in the art,

may be used if desired. The exposed portions ol' individual shingles constitute sixsided figures or hexagons,these hexagons' hein contiguous and covering the surface of too roof. The shingles may be fastened to the reel as they are being installed by driving nails through the saline near the corners as indicated at 11.

I claim:

l. The process of cutting shingles from a sheet of roofing material which comprises cutting staggered pairs of parallel lines longitudinally of said sheet, cutting transverse lines at the ends of said first named lines and joining the ends of said first named lines by cutting along diagonal lines.

2. The process of cutting shingles from a sheet-0f roofing material which comprises cutting staggered pairs of parallel lineslongitudinally of said sheet, cutting staggered transverse lines at the ends of said first named lines and joining the ends of said first named lines bycutting-alongdiagonal mes.

3. The -pr0cess of cutting shingles-from a sheet. of roofing material which comprises cutting staggered pairs of parallel lines longitudinally of said sheet, cutting transverse lines at the ends of said first named lines, cutting transverse lines joining the middle points of lines of the respectivejpairs, and joining the ends of'said first named lines by cutting along diagonal lines;

4. The process of cutting shingles from a sheet of roofing material which comprises cutting out rectangles in staggered positions, cutting along diagonal lines joining the corners of adjacent rectangles and cutting the portions thereby left into equal parts.

In testimony whereof I allix my signature.
