Patented Nov. 10, 1931 JOHN A. TOPPING, OF BBQNXV'ILLE, NEW YORK METHOD OF MAKING STRIP. SHIN'GLES Application filed June 27,

This invention relates to improvements in the method of making shingles.

An object is to provide a shingle which may be made by a single stroke of a guillo- 1927. Serial No. 201,572.

for using composition roofingis to apply it in elongated sheets the length of the roof and the full width of the sheet as manufactured.

This does not, however, present the desired P 6 tine, knife or a single revolution of a rotary ornamental appearance; Relatively small knife or roll-cutters thereby cheapening the cost of production.

A further object is to fashion the shingle Y or strip so that it may be cut from a progressively moving sheet of suitable material complete in all of its parts, and ready for immediate use, by a single operation and with a minimum loss of said material as waste.

A further object is to provide a shingle having its exposed or butt end in the shape of a truncated cone provided by tapering wedge-shape notches and in which a shingle unit has an edge at one end which provides one side or boundary of one notch and an edge at the other end which provides the other side or boundary of another notch by the said edges flaring in opposite directions, one to the rightand the other to the left.

Other objects, advantages and benefits of the invention will become apparent from a consideration of the following description in conjunction with the accompanying drawings forming a part hereof, wherein Figure 1 is a plan view of my improved multiple shingle, and showin the outlines of the shingle units by dotted lines.

Figure 2 illustrates one method of cutting shingles, a plurality at one time from a sheet, the shingles being cut lengthwise from the sheet.

Figures 3 and 4 illustrate two plans of cutting shingles, three at one time, from a sheet, the shingles being cutlengthwise from the sheet.

Figures 5 and 6 illustrate two plans of cutting shingles, one at a time, from a sheet, the shingles being cut transversely from the sheet and obliquely to the side edges.

Rolled roofing felt consists of a fibrous base impregnated and. coated with asphaltic material to make it waterproof and then usually finished with a layer of crushed stone or slate on one side.

The simplest and least expensive method individualroofing units, such as slates, tiles on shingles produce the more pleasing effects. ,These small individual roofing units require much more time and trouble to manufacture and additional expense and skill-to install. A compromise is arrived at by using multiple shingle stripswhich are long strips of roofing felt divided along their lower edge into a series ofportions or sections of sub stantially equal length and contour, each unit presenting the appearance of a separate shingle, althoughin reality they'are integrally united to a number of other similar portions. Roofing material especially when slate or gravel covered is hard'to cut, and this act is very destructive to the cutting knives or shearing edges employed. For this reason, the length of felt to be cut'for each shingle should be reduced to a minimum.

In Figure 1, my improved shingle strip 10 isshown to consist of three united shingles 10. The dotted lines 120i show a'continuation. of the oblique line 12, and when cuts are made along lines 12a and 12a, the strip 10 may be divided into three perfect shingles 10'. The boundary of the strip 10 isindicated by line'or edge a at the top and a at theflbot tom horizontal edge and the oblique line or edge 12' at one end and the oblique line or edge 13 at the other end.:-'The-edges a-a' are parallel, as also are edges 12 and 13. These'lines or edges form a geometric figure knownas an oblique parallelogram or rhomboid. This is also true of the individual shingles 10'. e a

The acute angular end or lowercorner of the unit is cut away as at 14, to form a'wedge shape slot 11 with the line or edge 12 of the adjacent shinglef The edges aand13 and the edges aa'ndlQ form .obtuseangles, respectively, and the edges a and 12 and a and 13, (before the part forming the wedge-shape notoh lll is cut away) form acute angles, respectively;

It will'be observed thatthe edge 14. bears the same angular relation to edge a as the of the wedge-shaped notches on opposite lonedge 12 bears to a, except that it flares in opgitudinal edges of the web.

posite directions, these two edges being the side boundary for the wedge-shape slot 11 which is formed by the proximate edges of two adjacent ends of separated shingles or strips.

This formation producesa taperedexpos'e'd butt Aof each'shingle-like unit-10'." If'th'e strip 10 be out along the dotted 1ines--12au- In testimony whereof I have hereunto subscribed my name.

there would be produced. thereby, as ;shown,,

three'perfect shingles 10 without further procedure, and each shingle:would ibean oblique parallelogram or rhomboid.

The strip 10 has a pluralityof uniformly" spaced inwardly extending wedge-shaped notches 11 in its bottom edge a to producea purality of apparently" separated shingles 1 In Figure 7,' the square end of the elongated sheet 16*from which the shingle unit's may-be out, is shown by dotted'lines which indicates the oblique position of thestripswithrespect to the sheet." It shows'also thatjlines 12 and 13 were fo'rmerlyth side edges of'the sheet."

Figures 5 and 6 show the adaptability of a guillotine knifekfor shearingthe stri-p'by a 7 single stroke, this beingiespecially true with respect to Figure '5. s s

, The shingle strips; or the individual shingles, maybe laid 'on a deck so-that'the notches 11 of the 'superposedcours'e mayb'e' located anywhere in vertical "linesfltake'n through similar notches ot the subjacent course, to produce varied effects and roofs of difi'erent,configurations. j

It is of course advisable for line edge a'of a superposed "course to be located above the apex of the Wedge-shape notches of the underlying course. V V

The: oblique joint produced "by oblique edges 12 and 13 produces a better; and-longer rain-resisting path'than when said path is at right angles to the longitudinal edges. of the course.
