ROOIING.

Application mea February 7, 1921. serial No. 443,016.

Be it known that I,.DONALD CUMFER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useimprove shingle-simulating strips in which a plurality of shingle-like sections are joined together in a single strip.

A particular object of 'the invention lis to divide the shingle-like sections by kerfs,

- indentations, depressions Or other visible token of division giving the appearance of actual separation, or slots, between the shingles.

Another Object is to provide a shingle strip in which bothof its sides vare covered with crushed or flaked slate, or the like. The slate ofthe respective sides is, preferably,of different colors, so that either side may be exposed to observation on the roof andA variations in decorative effect maybe thus vinexpensively pro-duced.

Another Object is to produce a strip in which the I transversely extending depressions or kerfs extend from the longitudinal edges towards the center of the strip on opposite sides thereof, so that the kerfs on the underside of the strip, whichever side is exposed to the weather, are not located immediately below the exposed surface.

Another object is to coat both sides of the strip, or roofing sheet, with slate receiving 4plastic and with slate, thereby preventing buckling on the roof, due to the unequal expansion and contraction of the product. Another object is to improve the quality l of the shingle strip by entirely covering both sides thereof with a material that is not sticky or visci-d.

Another object is to stiifen the sheet by application of the flaky material on both sides, so that it will be substantially unaffected, when on the roof, by wind pressure.

Other, further and more specific objects of the invention will become readily apparent, to persons skilled in the art, from a consideration ofthe following 4description, when taken in 'conjunction with the drawings, wherein Fig. 1 shows the sheet of roofing matcf rial coated on-both sides with slate, or the like, and ythe lines at which'thesheet is to be divided to make the shingle-simulatingstrips.

Fig. 2 shows a section taken on line 2-2 of Fig.V 1.

F ig. 3 shows the sheet of roofing material covered on both sides with slate and having the spaced kerfs in such way that the sheet is to be divided. longitudinally and trans'- versely into the shingle simulating strips.

Fig. 4 is a perspective view of a fragment of a finished strip. l

'In all the views the same reference characters represent corresponding parts.v

10 representsa sheet of roofing material comprisinff a fibrous base 11 upon which has ,been applied a relatively hard plastic material 12 of asphaltic nature usually employed in making roofing material of the type disclosed herein.` 13 is a covering ofcolored granular or flake slate, or the like, partially embedded vin the asphalt. 13 is a similarcovering of slate of preferably different color so that either side may be exposed on a roof to produce variegated color effect.

Shingle-like tabs or butts 14e-may be produced on each side of the strip 15 by de pressing the slate into the black asphalt, thus making stripes or kerfs and the visual effect of separation between adjacent butts. Shingle-like representations are thus presented to view on a roof. Similar kerfs or stripes of demarcation are made on the opposite side of the strip extending from the longitudinal edge toward the center of the strip and preferably in thesame transverse plane with similar kerfs on the opposite side of the strip. This renders the strip as a whole more flexible longitudinally, so that the shingles will lay closer to the deck without reducing their rigidity in transverse planes.

Figs. 1 and 3 show how the shingle strips may be cut from a sheet of roofing material without waste of material. By making kerfs or ydepressions 16 instead of actual separations between the shingle butts the shingle-like sections covered on both sides with a divided inineral, and having visible 'indications on both sides in the same retransverse center of the strip. d

2. A shingle strip provided with a suitable base having a plastic coating of asphalt on each side; a covering of divided mineral of contrasting color partly embedded in said coating and transversely extending indicating-kerfs at intervals in which the covering is entirely embedded in said asphalt, said kerfs extending from opposite edges on opposite sides of the strip, towards the other edge.

3. A shingle simulating roofing unit comprising a fibrous asphalt-bearingsheet having its opposite sides coated vwith plasticv relatively narrow depressions at spaced intervals, the stripesv made thereby extending from the respective edges Ytoward the transverse center of the unit, said stripes provided by submerging the fire resistant ma; terial into the asphalt to produce short black stripes, whereby either side of the unit may be exposed upon a roof.

In testimony whereof I hereunto sub scribed my name. v
