Application February zo, 1935, serial No. 1,331 s claims. (cl. 10s-7) This invention relates to shingles or strips for use in coveringroofs or sides of buildings, and particularly to asphalt saturated and coated, granular surfaced, felt basey shingles or strips.

`A general object of the invention is to improve that type of asphalt saturated and coated, granular surfaced, felt base shingle or strip which is provided with an overlay coating on at least a portion of the exposed portion of the strip for the purpose of increasing the weight and rigidity of the exposed portion as well as improving its weather-resisting qualities.

As heretofore usually made shingles or strips which have had an overlay or second coating have been so initially prepared that, in cutting the shingle or strip from the sheet, the cut has intersected both coatings. This has proved to be objectionable in that the two coatings have frequently tended to separate at the raw free edge thus exposed when the shingle or strip has been placed on the roof or the side of a building and exposed to extremes of weather.

Of course one of the primary purposes of pro- ,viding two coatings on a shingle or strip and cutting through the two coatings to form the butt end is to cause the shingle or strip to have the appearance of having a thickened butt somewhat similar to the butt of a wooden shingle. Because, however, of the objections to the laminated thick butt produced by cutting through two coatings, attempts have been made to produce the thick butt effect in other ways as, for example, by the Aprocess known as double-dipping or seal-dipping, which is a relatively slow and expensive process.

An important object of the present invention, therefore, is to provide an improved roofing or siding strip which will have the desired weight, rigidity and weather-resisting qualities of its exposed portions and which will at the same time produce the desired thick butt effect without the necessity for cutting through both coatings, a particular aim of the invention being to facilitate the production by machinery of thick butt simulating shingles which are-substantially free from` the objections to the machine-made thick butt shingles heretofore produced.

The invention also aims to produce a shingle simulating a thick butt shingle which can also be utilized with equalfacility to produce imitation brick siding.

other objects and important features of the invention will appear `from the following description and claims when read in connection with the accompanying drawings in which Figure 1 is an elevation of a roof or side wall covered with the novel shingles or strips of the present invention;

Figure 2 is a detail plan showing one method of producing these strips from roll roong;

Figure 3 is a. section on the line 3-3 of Fig- 5 ure 2;

Figure 4 is a section on the line 4 4 of Figure 1;

Figure 5 is a transverse section showing a method of making a modified form of the invention with a plurality of overlays on each strip;

Figure 6 is a section showing another modification;

Figure '7 is a plan view of an individual strip having an overlay with an irregular contour; 15

Figure 8 is a section on the line 8-8 of Fig- Figure 9 is an elevation of a roofj or side wall covered with strips of the type illustrated in Figure '1, and 20 Figure 10 is a modification in which the coating and surfacing are coniined to the exposed portions.

As hereinabove suggested, in practicing the novel method of the present invention and producing the novel shingle or strip, the entire sheet of' asphalt saturated felt base `rooflng 2 is rst coated with a layer of asphalt 4 over its entire surface and is then provided with a surfacing of mineral or articially prepared granules 6, also 30 over the entire surface in the preferred manner of practicing the invention.

If the roong is of such a width that four of the shingles or strips may be cut from its width there will then be superimposed upon the original surfaced coating fom' strips of overlay coating 8 in the form of two pairs of strips, each pair being spaced from the outer edge of the sheet a distance equal to the head lap of the shingle,

the strips of each pair being spaced from each 40 other twice the distance of the desired exposure of the original surfaced coating at the lower edge of the strip or shingle. It will be obvious that the two pairs of strips 8 othcr'a distance equal to twice the' desired head lap.

The strips of overlay coating 8 havingbeen applied to the sheet in any suitable manner as, for example, by rollers dipping into a supply of 50 the coating material, these strips are 'then surfaced with any suitable granular Vsurfacing material I0, which is preferably of a color different from the surfacing material 6 so as to provide a contrast at the lower end of thel exposed part 55 are spaced from each 45A vof the shingleror strip where the original surfacing t is still exposed.

The sheet is now ready for slitting to form the individual strips oi` shingles. It will be obvious 5 that in a sheet suchas shown in Figure 2 where tween the strips 8 of each of the pairs of overlay l0 strips and the third slit Il being along the median line of the sheet, that. is, half way between the two pairs 'of overlay strips l. v

If it is desired to make shingle strips having a plurality of tabs formed by cutouts I8 in the exposed portions of the strips, these cutouts will preferably be formed as a part of the slitting and strip-forming operation.' n

In Figure l is shown a roof made up of three tab strips having cutouts I l formed in'any suitable manner, these strips having each a band or margin 20 at its lower edge where the original surfacing 8 is exposed. This, by contrast with the surfacing lo, gives a shadow eifect at the lower edge of each strip or tab and thus, with the overlay coating and surfacing, adds to the impression of butt thickness.

It will also be noted that the slots I 8 expose a part of the original surfacing. Thus the shadow effect of the slots is also emphasized. Moreover,

when it is desired to make these strips of such proportions that they can be used to produce imitation brick siding, by suitable coloring of the original surfacing 6, the slots I8 and the exposed margins 20 of the original surfacing will produce the eilect of mortar lioints.

It will alsobe noted that in causing the overlay coatings l to coverall of the exposed portion of the strip or shingle except the margin at the lower edge, a gage line is provided at the upper 4o edge of the exposed portion of the shingle or strip which facilitates the laying of the shingle or ,strips with the desired uniform head lap, the course next above being laid with its lower edge abutting the upper edge of the overlay coating 8.

45 In Figure 5 is shown a modification of the invention in which, instead of a single overlay coating, a plurality of overlay coatings is provided, each surfaced before the succeeding coating is placed thereon and each preferably set back from 5o its under coating a short distance to emphasize the thick butt simulating eii'ect. In the Figure 5 modification there is provided, besides the original coating l, two successively set back coatings 22 and 24.

5s In Figure 6, instead of providing a coating at the lower margin of the shingle or strip of the Where it is desired to relieve-the monotony of giving the lower edge of the overlay coating an 75 irregular contour, as shown particularly in Figures 7 and 9. Such an irregular contolxr of substantially one-dimensional character can be given by cutting back portions of the edge of the coatoverlay coating and using a roller with an irregular edge for each overlay application. As in the other forms of the invention, the margin 2l will preferably consist of the original coating 4 and surfacing 8, whereas the overlay coating indicated 15 asNinFigure'Iwillbe'thepartthatwillbe given the irregular contour Il.

In the modification of the invention shown in Figure 10, the coating and surfacing, both the asphalt saturated felt base, which may be covered with'any suitable non-sticking material such as powdered soapstone. 25

From the foregoing description it will be obvious that the invention provides not only an improved shingle or strip construction in which the exposed edge is cut only through a single separate when exped to the weather, but that the invention lends itself to machine manufacture and to the ready production of artistic eii'ects.
