The invention relates to prepared roofing and particularly to that which is formed in strips having notches extending transversely into the strip at intervals along one edge of the same tosimulate the appearance of separate shingles when the strips are laid upon the roof in overlapping relation. Among other objects the invention is 1ntended to rovide a new .form of shingle 10 strip which afiords more complete protection for the roof upon. which it is laid and an im roved method of makin the same invol 'ing an economical use the sheet material from which the shingle strips are 16 produced.

In the accompanying drawings Fig. 1 is a p an view showing a plurality of overlapping courses of the improved shingle strips as they may be laid upon a so roof, the relative position of the upper or covered edge of the first underlying, course being indicated in dotted lines and that of the second underlying course being indicated in dot and dash lines. as Fig. 2 is a side elevation partly in section representing somewhat diagrammatically suitable apparatus for forming the improved strips from an elongated sheet or web or material.

' Fig. 3 is a plan view of the apparatus of Fig. 2, the outline in dot and dash lines indieating a line of severance of the material. upon a subsequent operation of the mechanism and indicating also the complementary relationship of the front and rear edges of the shingle units.

Fig. 4 is a plan view showin the end of the web or sheet of material aiter it has been severed to remove the preceding unit.

,40 The position of the next line of severance (to remove the material forming the slots between the tabs) being indicated by the dot and dash line.

Figs. 5 and 6 are plan views of different forms of shingle stri is or units having different fshingle ta'b contours and correspondingly difl'erent contours for the projecting tabs at the rear edges of the units.

The improved shingle strip 10 is prefer- 6 ably of suflicient len h to comprise a plurahty of connected ingle tabs 11, shown as four in number, with. intervening slots or gutters 12. Theseshin 1e tabs constitute the portion of the strip w ich is exposed to the weather, when in use. A desirable ornamental appearance and other advantages are obtained without in anywise detracting from the utility of the stri if each of the shingle tabs 11 is formed wit chamfered corners 13, thus providin widened or flaring spaces between the en s of adjacent tabs. The line of chamfering of the corners 13 mayextend advantageously at an angle of 45 to the front edge of the strip and reach to half the length of the intervening slots or gutters 12.

Under these. circumstances the remainder of the'strip 10 may comprise, without waste of material, a continuous body portion 14 having the fullwidth usually provided for the portion of-a shingle strip which is to be covered by succeeding layers of similar strips, when in use, and a series of. extensions 15 arranged along the back or covered edge 16 of the strip in line with the gutters or slots 12. It fol material removed from between the outer end portions of two ad'acent shingle tabs 11, a plurality of the shingle strips 10 ma be completely formed from a length of we I ows that if each of the extensions 15 conforms in shape with the,

17 equal only to the. combined widths of the strips from the free edges of the shingle tabs 11 to the rear edge 16 of the main body portion '14 of the strip. When this con- 'struction is used the only part of the original web 17 which is discarded comprises the short tongues '18 removed from the inner end portions of the slots 12 (for example as shown in Fig. 4) while the full width of the shingle strips 10 from the free edges of the shingle tabs 11 to the rear edge 16 of the main body portion'14 of the strip may be only two and one-half times the length of the shingle tabs and still permit of the strips being laid upon the roof with the full length of the shingle tabs exposed to the "weather and with two. full layers of roofing material covering all parts of the roof to the inner ends of the gutters or 'slots 12.

The strips may befastened desirably to the roof as usual with nails 19 introduced "ust above the inner ends of the slots 12. e nails are thus covered by the shingle tabs 11 of the next overlying strip and each one of the extensions .15 is firmly held to the roof by reason of its position, in this instance," under two overlying strips which are in turn fastened to the roof at a point immediately beyond the end of the extension.

The strips 11 and discarded tongues 18 may convenientl be cut from the web 17 by a machine em dying certain of the principles of Patent No. 1,249,544, granted to me, December 11,-1917. In using a machine of this character, the web 17 is continuously advanced upon a cutting table 22, preferably by feed rolls conveniently represented at 20 and 21. The cutting table 22 cooperates with a rotary knife 25 and these two parts are provided with complementary fingers 23 and slots 24 havin respectively widened bases 26 and throats 2 conformin in shape with the slots .12 and chamfered ta corners 13 of the shingle strips.

In the o ration of the machine, the ro-.

tation of t e knife 25 is of course so timed with reference to the rate of feedin of the web 17 that. a ski le strip 10 of fn width is struck ofl from t e end of the web at each downward movement of the knife over the edge of the table. A second knife 28, rotatmg upon the same axis with the knife 25 and preferably rigidly connected thereto,

. serves to strike oi the tongues 18 which I This application is a of the strip chine illustra in would otherwisgipgroject from the extensions 15 at the back e of the sh' 1e stri As ehosvn, tha knife c2,18 is of silo lagt and is ispose atsu ana ewi respect to the knife 25 that it co d rates with the fingers 23 of table 22 to eer the ton cs 18- from web 17 after each. operation 0 the knife 25 as indicated by the dot and dash line 29 (Fi 4 It will be understood th the le tabs 11 may have rounded-en as 30 1g;
