SHINGLE STRIP. l y
Application led October 2,1924. Serial No. 741,118.
v This invention relates to improvements in shingle strips, and specifically contemplates so severing and slitting a continuous sheet of previously prepared roofing material as to produce individual shingle strips, which when laid on a roof, present correspondinghexa onal areas of light, dark and shadow. lThe lnvention is characterized by the fact that the strips can be produced with-out any waste in cutting and are self-spacing relative each other, when placed on a roof;
Briey, the Sheet of previously prepared roofing material may be completely severed centrally of its length and adjacent this central line of severance at right angles thereto is also completely severed at prededetermined intervals corresponding to the width desired. Communicating with each of the latter vertical lines of severance, is a right angled cut, parallel to the central line of severance. From the latter line of severance are communicating diagonal lines of severance, the outer set of diagonal lines connecting With a relatively short line of severance, again parallel to the central severing line. This relatively short` line of severance communicates with right angled lines of severance, terminating at the edges 'of the roofing sheet. Further, 'a set of op posed half hexagonal incisions are produced intermediate each complete line of severf' ance. The individual strip thus produced has u per and lower straight edges while the si es are staggered relative to the upper and lower edges, but parallel to eachother,
' having semihexagonal incisions in 'the body thereof."` The lower portion is then folded along theunbroken connecting lines'upon the upper body portion, resulting in the' formation of a stri exhibiting perfect hexagonals, which 'w en laid on a roof,
resents a series of staggered or parallel liexagonals of alternately contrasting light and dark colors.`
Many wdvanta es will be apparent to those skilled in e art, among which may be mentioned the economy. of construction, the self-spacing when laid ona roof, the reinforcing structural characteristics produced, and the attractive hexagonal areas of contrastin .color presented to `the eye.
In the rawings;
Fig. 1'is a plan view of a continuous roofing sheet severed and. incised to l produce my improved shingle strip. f
171g. 2 is va plan view of the individual strip wlth the lower portion' folded over the upper portion.
Fig. 3 is an edge view of the construction .shown 1n Fig'. 2.
Fig. 4 is a plan view of the strips aslsembled in place on a roof, illustrating one form of arrangement. Referring in detail to the drawings, l designates as a whole a continuous sheet of felt previously saturated with a ,Waterproof-v ing composition, and one or both surfaces of which may have imposed thereon a granular surfacing of a predeterminedv color, althoughA in the preferred form of invention, one surface only may be coated with the granularmaterial, the opposite surface presenting a plain appearance, for instance, black, where asphalt is used as the saturant. The granular material may be any color such asred, green, gray, slate, etc.
AS this sheet is fed forward, it is longitudinally severed centrally of its width along the line 2, and also vertically severed along the line 3 bisecting the line 2. The
lines 3 terminate in right angle severing lines 4, from Whichextend diagonals 5 .and 6. The diagonal 5 terminates within lthe body of the material, while the diagonal lin(` 6 has a short angular extension 7 parallel to the central line of severancel 2. The latter extension 7 terminates in a right angled severing line 8, which terminates adjacent the edges of the sheet to produce complete severance. Intermediate the edges of each shingle strip are produced semi-hex-l agonal incisions 9 for a purpose hereinafter explained.
The individual shingle strip produced by severing a sheet of roofing material as de scribed heretofore, has u per and lower straight (parallel edges While the sides 'are staggere -relative to the upper and lower edges, but the staggered lines per se are parallel to each other. Thebottom portionof the individual shingle strip along the unsevered lines between the 'extremities ofv the semi-hexagonal lines of severance, and the sides being staggered relative to the upper and lower edges, a novel and attractive appearanee is the result. The extremities of uns the incisions 9 within the body of the sheet preferably terminate ata point beyond the longitudinal central cross section, yin order that the upper edge of the'portion which is folded over may project beyond the upper edge of the portron which has not been folded. In this Way, there is formed parallel or staggered hexagonalv4 areas when the strip is laid on aroof in combination with other strips, While at the same time utilizing the particular construction of the strips to accomplish their own vself-spacing.
One surface only may have granular material applied thereto of a predetermined color, While the other surface-may be devoid of granular material and present the color of the waterproofing material, for instance, black, where asphalt is the waterproof material used. Thus, the assembled shingles on a roof present contrasting hexagonal fields of dark, light and shadow, as shown.' Or, both surfaces may have granular material imposed thereon, of different colors, for in-` stance, red and green, slate and red, etc'.
Further, the shingles may be so laid as to present parallel areas of light and dark,` or they may be staggered relative to each other.
The strips may beheld in place by any suitable means, such a's hollow nails, etc., driven into the bod portion and concealed from view by the folded portion. The entire construction is extremely sturdy, and the reinforcing qualities of the doubled ply will be instantly appreciated. Furthermore, the finished roof gives the impression of solidity `and strength, combined with beauty and attractiveness.
It is understood of course, that shingle strips can be produced froml a sheet half aS Wide as that described, thus eliminating the line 2.
I claim as my invention:
1. A shingle strip vof greater Width than length, having two parallel straight sides and two sides staggered relative the stra-ight sides but parallel with each other, having a semi-hexagonal incision in the body of the strip, and folded along the lines of the. semihexagonal incision to produce hexagonal areas.
12. A shingle strip of greater width than length having on one surface granular material of a predetermined color and the opposite surface presenting a contrasting color, having two parallel straight' sides and two sidesl staggered relative =thejstraight sides but parallel With each other, having semihexavonal incisions in the body of the strip, and folded along the lines of the semi-hex vv'agonal incisions to produce hexagonal areas grally connected overlying portion folded.
upon the body portion, sald overlying portion being of substantially thesalne configuration as'the body portion.
4a.. As a new article of manufacture, a
flexible roofing kstrip originally having onl one' surface granular material ofa predeter mined color and originally on the opposite surface a contrasting color, comprising a strip having parallel' longitudinal edges, sides disposed partially at right angles and partially staggeredv relativev said longitudinal edges but parallel with each other` the base of said strip exhibiting alternate cntout portions and interposedtabs between the cut-outs, both being substantially semi-hexagonal in shape and an integrally connected overlying portion folded upon thebody portion to produce' hexagonal. areas, the latter bein of substantially the same configuration as the body portion, but of a 'contrasting color.
5. As anew article of manufacture, a flexible rooting strip comprising a body portion having granular material of a. redetermined color imposed thereon, and an integrally connected overlyin portion of the same contiguration as the body portion, Ahaving a surface of contrasting color and disposed in a plane offset from the plane of the body portion.
