STRIP SHINGLE.

`origini-i1 No. 1,326,899, dated To all who/m, it may concern:

Be it known that I, HERBERT ABRAHAM, a. citizen of the United States, residing at the city,.county, and State of New York,

have invented certain new land useful Improvements in Strip Shingles, of which the following isa specification.

One of the objects of the inventionis to vproduce strip-shingles of such form that'a given area of roof deck can be covered and made watertight with a smaller quantity of material than has heretofore been required.

Another object is to produce a shinglestrip"having a plurality of'tabs along itsl up er edge. A still further object is to cut the-strips so that the cutaway portions of one rowA of shingles| forni the tabs `of the adjacent row. f A further object is to 'eliminate the likelihood of curling by removing the .corners of the shingle-,like portions and utilizing the material cut away from onestrip to form the tabs of an adjacent strip.

This invention pertains particularly to an improvement instrip-shingles of the type having their lower edges slotted at intervals so that when laid iii overlapping courses they will simulate the appearance of indi-4 j vidual shingles. a

Heretofore in the art, with strips of that type, having, for example, substantially the Morel generally considered, my improved shingle-strip may be defined as one having parallel straight longitudinal edges, with he lower edge indented at intervals by recesses leading into slots' toprovide shingle-r invention relates to strip-shingles of. .Prepled roofing j.

Serial No. `483,063.

Figure 21s a "view of a ,fragment of a sheet of prepared roofing indicating the preferred method of manufacturing the shingle-strips;

gigure 3 'is' a section of laid strip-shingles, an i a Figure 4 is a modication showing a stripshingle having semicircular shaped tabs.

According to my invention, I take a sheet of prepared roofing and cut out .,a plurality of rows of small oblongishaped openings 1, the openings in any one rowv being preferably, though not necessarily, disposed midway between the openings in the adjacent rows. In the completed `.strip-Shingles, shown in F iguresl and 4, these,l openings form the slots between the adjacent shinglelike portions. The sheet is Ialso severed along wavy-like lines 2'intersecting an end of the openings,as shown in Figure 2. The cutting of the lines 2 may be performed either separately yor simultaneously with the cutting of the openings lThis produces aV multiple shingle-strip having a seriesof tabs 3 along its upper edge, and having its lower edge formedof a. series of straight lines extending parallel to the major axis of the strip and separated by slots opening into cut-out portions or recesses which substantially correspgnd in shape to the tabs, said tabs on lthe upper edge being preferably, thoughnot necessarily, disposed in staggered relation to the cut-out portions of the lower edge. The strips are generally cutinto blocks of four shingles each, as indicatede in Figure 2, to form the completed article/shown in Figures 1 and 4. It will be seen by reference to Figure 2 thatthe tabs r3 of any one strip are formed of material cut out to provide the recesses of the adjacent strip, which recesses respectively lead into the slotsof said strip. Tn this way thev shingle-strips are produced without lossof material other than that caused bythe cutting out of the openings 1 andfbthel necessary l trimmingjof the sheet.- 4

By varying the character( of*` the cutting line 2 the tabs 3 may be made-of 'other thany triangular shape, for example, they `may .be`

of'semi4circular sha-pe,` `asishown inFigure 4L Preferably the strips are fastened to the roof deck by means `of nails driven" above the slots as illustrated .in ligulre 3, it being understood that the Lnails of" *each lowerl course are covered by the course next above. When strips of the proportions shown are used the nails will penetrate thrdughthe tabs of the strip below, in which case the tabs will n function as nailing tabs. A Howeverfif wider strips are used, then the nails vwill penetrate the under strip through the bodyi of the y strip.

Asshownin thedrawingdl the depth of i the combined recessesand slots, which 'define the extent that the strip is tc be exposed the width of t ofthe strip `To securelthe greatest econ-- muyy of material I.` refer toiemploy'stripsl be substantially one-half of when; laid ma 9 he individual shingle :portions vi'flfierein` the width 0 themstrip,excluding the tabs, is twice the depth of the combined reg -'cesses and slots and laid inthe manner It will beseen that the `overlap `measured vertically between the uppery ends of the slots of any course andthe uppermost portion of l the next underlying course` will, at the mint mulini be ,equal to the altitude of,` the tabs, thus providing substantially the same protec'- l` tion against leakage at those points as` is afforded b"-`v the old type of shingle-strip` 'ofv correspon ing over-all' width, but with' a considerable savingy of shingle material.

c, Obviously, however,y the width mofthe body l bined recesses and slots will v-beless than oneu iss tion.

portion, of the strip: may,` be increased without departing from thescope ofl `my inven-n Thus it may be advisable to usefwidery strips'in' which case the'depth of the comhalf .ofthevwidthfofA the bod portion. This will require a corresponding y greater quan#` tity of material tolcov'er a given-area of roof deck, but `will still` result in .a substantial;
