SHINGLE AND METHOD 0F 'MAKING'.

Application led December 14, 1922. Serial N'o. 606,860.

To aZZ whom t may concer/n:

Be it known that I, ROYCE A. RUEss, a citizenof the United States, residing at Washington, in the District of Columbia,

have invented certain new and useful Im-A provements in Shingles and Methods `of Making, of which the following is afspiacification. l, f

This invention relates to certainy 'new and useful improvements in shingles andrvm'ethfd of making same and pertains morelespecially to shingles of the strip type invclvinga felt base saturated and surfaced with bituminous matter and having a coating",(ifl 'crushed' forded by the provision jlcfiun'coated areas' or portions that are free o mineral matter and which aline with the'fci'its in the felt base, but attempts tomanufacture the shinles with such uncoated areas, has proven difficult, and expensive to a prohibitive extent. Inl the manufacture of shingles of the strip type, the custom is 'ro apply and then roll crushed mineral matter onto a felt base saturated and surfaced with bituminous matter, and to then cut or notch the product to impart the appearance of individual shingleswhen assembled on a roof. The present invention therefore aims to provide a stripshingle which somewhat adheres to the present method of manufacture, and which at the same time affords a simplified manner of hinging, which latter is 'formed by simultaneously depressing the mineral matter in the underlying coating to form hinging 'means the cutting of the slots in the with the present invention;

Figure 2, is a section on line 2-2 of Figure 1;

Figure 3, is a cross-section of a set of rollers employed in making the shingles when feeding the strip transversely of its length;

Figure 4, is a section on line 4--4 of Figure 3;

Figure 5, is a view similar to Figure 3, of a set `of rollers employed when making the shingles by lengthwise feeding of the strip;

Figure 6, is a section on line 6-6 of Figure 5;

Figure 7, is an edge elevation illustrating the manner of folding the shingles.

Iny proceeding in accordance with the present invention the felt or other basev 1 is saturated with a relatively soft bituminous mixture, then coated on 'bothysides with a harder bituminous composition` 1li and then surfaced on the upper` side withmcrushed mineral matter la. The strip isfow vpassed in the direction of its length between, rollers 2 and 3, Figures 5 and 6. Thefupper roller 2 is provided with an axially extending rib 4 which may be of V-shape or semi-circular shape in cross-section and is further provided with an axially extending cutter 5,

the latter being of the width which the slots 6 of the strip is to possess, the rib and cutter being in alinement. In operation, the roller 2, serves to depress the mineral matter into the underlying coating and at the same time to form the slots 6 and V-shaped indentations 7 which latter afford the hinging means. The indentations 7 extend for some distance into the coating, without however extending into the felt base, which would weaken same. The roller may be formed hollow so as to be heated by steam or other means; or if desired the roller may o erate under pressure in a cold condition while the material is still warm and plastic.

In lieu of rolling, cutting and forming the hinging means by lengthwise feeding of the strip, the same result can be produced by feeding the strip transversely of its lengt as illustrated in Figures 2 and 3, wherein rollers 2a and 3a of the same length as that of the strip is employed. In this instance, the ribs 8 and the cutters 9 are of arcuate form and are arranged circumferentially of the roller and at spaced distances axially of the roller equal to the width of the shingles or slots defining the shingles. Longitudinal or axially extending cutters 9a are employed to longitudinally cut the strips from a single large piece of material, wlnle as shown in Figure 6, circumferential cutters 10a are Yemployed to transversely cut the 4large piece of material into strips.

In each form of the invention it will be seen that the ribs act to form the indentations while the cutters cut or punch out the slots', the roller at the same time pressing or rolling the mineral matter into the coating, the three operations bein accomplished by and upon mere rotation o the rollers.

The indentations aline with the slots 6 and are moreover coated or covered with the bituminous coating so as not to expose the underlying felt, the mineral particles being pressed into the coating, resulting in the formation of indentations.

Obviously in each form of the invention, the rollers may be made as long as desired to enable as many lengths of shingles to be cut in one operation from a single iece of material of required size, as desired.)

What is claimed is 1. In a folding strip shingle, aV flexible base having an adhesive surface coating and having spaced cuts formed in one side edge and with the inner ends of the cuts spaced from the opposite side edge, the parts of the coating between the inner ends of the cuts and the opposite side edge of the stri-p having indentations alined with the cuts to provide hinging means, and a coating of crushed.

mineral matter secured on the adhesive coating and covering the indented portions thereof.

2. The herein described method of making strip shingles which consists in coating a iexible base with an adhesive substance, then in applyin crushed mineral matter on the adhesive su stance and then in rolling the mineral matter and about which the i str ip may fold.

3. The herein described method of making strip shingles which consists in coatin a flexible base with an adhesive substance, t en in applying crushed mineral matter on the adhesive substance and then in applying pressure to the mineral matter and simultaneously forming slots in one edge of the base to form individual appearing though interconnected shingles and depressing the mineral matter at points alined with the slots to form indentations covered with and reinforced by the mineral matter and about which the strip may fold.

4. The herein described method of making strip shingles, which consists in coating a iexible base with an adhesive substance, then in applying crushed mineral matter to the substance, and then in cutting spaced slots in one side of the base, and simultaneously exerting pressure upon the mineral matter to depress the latter in to the base and to form lines of weakening covered4 by the mineral matter and about which the base may be folded.

5. In a folding strip shingle, a flexible base having spaced cuts formed in one side edge and with the inner ends of the cuts spaced from the opposite side ed e, a coating of crushed mineral matter a xed to the base, and indentations formed .in the mineral matter in the parts thereof alined with the cuts to provide hinging means.

In testimony whereof I aiix my signature.

ROYCE A. RUESS.
