SPEEB, OF BUFFALO, NEW YORK, ASSIGN'OR 1'0 CERTAIN-TERI) PBODUCTS CORPORATION ROOFING Application filed February 18, 1930. Serial No. 428,024.

This invention relates to the art of roofing and contemplates the production of an improved type of colored or design compos tion roofing together with anew and s1mpl1- 6 fied process of making same.

Colored or design composition roofing has heretofore been made in various ways all of which have required numerous kinds of equipment a large part of which is designed to apply numerous coatings of water-proofing compounds and surfacing materials. These operations are difiicult to perform properly and require heavy and cumbersome apparatus which requires considerable trouble and expense to keep in working order;

cated methods have heretofore been required in making the type of roofing above referred to, thus .necessitating heavy production expenses, It is an objectof this invention to 4 produce a colored or design roofing in a simple and economical manner,.elimmating the unwieldy and uneconomical equipment and processes heretofore used.

Another object of the invention is to provide a way to make colored and/or design roofing by means of a processwhich utilizes the equipment now in commercial use for making ordinary plain composition roofing. The addition of very simple apparatus to roofing machines nowin use will enable my novel process to be followed out and will result in the production of the-new and improved colored or design roofing herein set out. 4 Other objects and advantages of the present invention will hereinafter appear when reference is had to the accompanying specifications and drawings in which Figure 1 is a diagrammatic view of an apparatus for making my improved roofing material.

Figure 2 is an elevation of a pressing roll which may be used with my invention. I

Figure 3 is an elevational view of a different form of pressing roll.

Figure 4is a sectional view of a piece of roofing material made in accordance with the invention. 7

Figure 5 is a fra entary plan view of a iece of colored an /or design roofin made 1n accordance with the invention, an I Figure 6 is a plan view of a roofing element made in accordance therewith.

In the drawings, 'lv represents a continuous strip of bituminous saturated material such as commonly used as a foundation sheet for composition roofing. The sheet is taken from a large roll and passed over rollers 2, 3, 4 and 5 and between rollers 6 and 7 which are positioned above a tank containing a thick mastic water-proofing material, 9. Roller 7 revolves in the water-proofing material and applies a continuous film of the compound to one face of the saturated sheet. If desired, the foundation sheet can be passed directly through the bath of wate'rproofin coating material so as to coat same on all si es. This water-proof coating will hereinafter be referred to as the coating. Y

After the coating is applied the continuous strip is passed over the roller 10 and is then fed between pressure rolls 13 and 13'. Just prior to application of pressure, surfacing material 12, consisting of grit of any suitable nature and color, is applied uniformly over the top surface of the coating from hopper 11 which distributes it over the face of the sheet in the usual manner. This surfacing is pressed into the coating by roll 13, when the sheet passes through the pressure rolls. .The roofing is now passed over reverse roller 14 so as to dislodge any grit which has not been thoroughly pressed into the coating, and is then run through cooling apparatus and through loopers in the ordinary manner.

While the roofing is still warm a uniform layer of a difl'erent colored or different kind of grit 19 is applied thereover and the strip is run under a forming roll 20 which has 100 raised portions 20' provided thereon in any is applied. Layer 12 is obliterated and completely embedded in the coating where pressure is applied and the surface at the points of pressure, is covered with different colored grit 19. Figure 4 shows this construction. The pressure will ordinarily hump up adjacent portions of the coating and surfacing material as at 27 and 28. This hump can be retained in the finished roofing or can be pressed down by subsequent rollers as desired. T preferably leave the humps thus formed in the position they originally take in order to provide a finished material which is more or less in relief and which gives a decided shadow efiect between the colored areas.

After the second colored layer has been impressed into the desired pattern the sheet is reversed over roll 20 .and the remaining amount of surfacing 19 falls off into trough 23 from which it is removed by a screw conveyor or other suitable means. The roofing is then passed over roller 22 to right it and can then be taken out of the machine in the desired form. Tn the embodiment typified the roofing is passed through cutting rolls 24 and 25 and cut into units 26, e. g.

. as illustrated in Figure 6. If the design roller illustrated in Figure 3 is used, I prefer to cut the material into strips precisely like that illustrated in Figure 6.

Obviously any form of design may be placed on roller 20 and that same design vgllll be transferred in color onto the roofing s eet.

It can be readily seen that the above described invention eliminates entirely the various complicated and uneconomical mechanisms and processes heretofore used in making colored roofing. The ordinary mode of making composition roofing can be utilized with the mere addition of hopper 18 and design roller 20. There is no necessity of successive applications of coating materials in predetermined areas and of subsequent separate applications of different colored grit to those areas. In this simple manner colored and/or design roofing can be obtained in any desired form with a minimum amount of expense in equipment and in operating cost. If desired, roller 20 may be used without any second surfacing material; this results in a product having dark lines of demarcation where the design ridges 20' press and immerse the first surfacing material into the coating. I

Attention is directed to Figure 4 which clearly illustrates the nature of the product obtained by the herein described invention. Base 1 is provided with coating 9 which is of continuous depth except where pressed down by roller 20 to embed grit 12 and if desired to apply different colored grit 19. The surface of the material is generally flat and has distinct areas 12 of one colored grit and a distinct pattern '19 of a different colored grit all of which grit is firmly embedded in a water-proof coating so as to form a strong,

well constructed composition roofing and to present a neat and ornamental appearance.

The invention herein is not limited to the particular embodiment illustrated but can be utilized in various ways to produce any kind of design roofing or waterproof covering material, although the designs may ordinarily be such as to simulate shingles for roofing and bricks or masonry for siding. The invention is in no sense limited to such simple designs.

Having thus described my invention ll claim:

1. The process of making colored roofing which includes the step of pressing, in predetermined patterns, into a sheet of ordinary grit-surfaced composition roofing portions of a layer of colored grit loosely overlying the grit surfacing. I I

2. The process of making designs in gritsurfaced composition roofing comprlslng pressing into said roofing in predetermined areas portions of an overlying layer of grit of difi'erent color.

3. The process of producing a design upon a covering material having upon at least one side of a base sheet a surfacing of granular mineral material adhering to an adheslve coat-ing upon said side of the sheet which comprises spreading upon said mineralsurfaced side of the sheet a layer of contrasting granular material without regard to the desired design, partially embedding in said adhesive coating portions of sand layer of contrasting granular material to form the design, and removing the portions of the layer which are not so embedded.

4. The process of producing slate surfaced roofi g which comprises surfacing with gra ular slate an asphalt coating upon a sheet of roofing felt substantially to cover the asphalt coating, applying upon said slate surfacing a layer of contrasting slate without causing it to adhere to said coating, pressing portions of said contrasting layer to cause them to adhere to said coating, and removing the unpressed portions of said tea " are its layer to leave the design in the pressed sheet material exhibiting surface designs which comprises coating a base sheet with a plastic adhesive, covering the adhesive coating with grit surfacing material so as to render the surface substantially nonadhesive to additional grit which may fall thereon covering the surface thus protected by the first layer of grit with a second layer of grit of color contrasting with that of the first, pressing portions of the sheet which are to exhibit the grit of this second color so as to press said second layer down into adhering relation to the adhesive coating, and thereafter removing the second layer of grit from the areas which have not been pressed.

6. The process of making waterproof covering having a grit surface exhibiting surface designs which comprises forming a plastic adhesive base, covering the surface of said base with a layer of non-adhesive material adapted to be broken through by surfacing grit, placing a layer of one such surfacing grit over the base thus covered and so,

as to cover the design areas in which it is to be exhibited, and to extend beyond the boradhered thereto.

7. The process of making waterproof covering material as defined in claim 6, in which the material for rendering the surface nonadhesive is,a surfacing grit adapted to form apart of the design.
