4 Claims.

This invention relates to improvements in shingles and has particularly to do with shingles, for roong and siding, of the construction as hereinafter described and having impressed therein a shallow design or pattern so as to closely resemble the pattern of the grain and texture of wooden shingles. It is the principal object of this invention to provide a relatively heavy shingle (individual or strip, though preferably lndividual) which, because of its thickness and construction, is relatively stiff and rigid and better able to resist normal bending stresses due to the weight of the shingle and the influence of heat of the sun and the consequent tendency of the asphalt constituent thereof to deform and, also, because of such construction, to receive a pattern or design to imitate the eroded depression or irregular pattern and texture of the grain of wooden shingles. invention to provide such an indented pattern shingle presenting thereon an all-over substantially uniform color eiect and wood textured appearance and without producing appreciable shadow eiects. Despite the indenting of such pattern, due to such irregular indentations and their small diierence in relief or departure from the surface plane of the shingle, from a distance, the shingle appears to be coa-rse textured, that is, the pattern appears to be on or at the plane surface rather than as indented therebelow. 'I'he effect of the design impressed in the shallow sloping-sided indentations apparently is to change the reflected light coming to the eye from the oblique surfaces thereof as compared with the light coming from the normal or plane surface of the shingle and this difference produces suiilcient variation in light reflection to show the design and impart to the shingles when on the roof a textured appearance, and without producing an appreciable shadow eifect.

An additional advantage of the shingles of this invention is that any ordinary unevenness in the structure or surface to which they are attached is not apparent on the roof as laid, and, so to speak, is obscured by the texture of the shingles for they do not, as is true of asphalt shingles heretofore, present or depend upon a fiat even appearance, nor is a good appearance so dependent upon precision of laying. Asphalt shingles as now known and used give a flat appearance, without life and their appearance, to a very considerable extent at least, is dependent upon the exactness with which the shingles are laid so that the edges and/or similar angles line up as viewed in perspective from any one of various It is the further object of this' different points. Due to the herein described features of this invention, such angles or lines are not readily apparent, the primary and distinguishing feature of the shingles being their texture or design features imitating the appearance of the grain of weathered wooden shingles.

In the drawing which illustrates the preferred form of the invention:

Fig. 1 is a perspective view showing a siding shingle made in accordance with this invention; and

Fig. 2 is a cross-sectional View, somewhat enlarged, showing the cross-section at and adjacent to an indention.

Referring to the drawing in which like numerals represent like parts,the shingle shown is made up of the usual asphalt saturated felt base 2, having thereon and throughout the extent of its upper surface a layer of asphalt 4, which in turn has partially embedded in said layer of asphalt 4, a layer of mineral particles 6. This layer of particles 6 is, in practice, ordinarily made of crushed mineral matter, natural or artificially colored. This layer of mineral matter preferably covers the entire asphalt coated surface of the shingle as shown. In addition to the layers 4 and 6 just referred to, there is applied, at least to the weather exposed part of the shingle (and if desired, all over the shingle) [an additional layer of asphalt 8 and superposed thereon a second layer I0 of mineral particles which, in imitation of stained and weathered wooden shingles,"I

isordinarily gray, green, brown or bui in color. The stiiening comes primarily from the two layers of mineral particles each of which, in eiect, due to the binder, functions largely as a layer of hard solid material which is not so easily subject to deformation by normal bending stresses as are the more readily deformable asphalt layers.

that said indented particles are obscured to any extent by the asphalt. As a practical matter, in the manufacture of the shingles of this invention, the asphalt in the areas of the indentations while warm is laterally displaced to a considerable extent so that layers 6 and I0 of mineral parbut still substantially the same weather-protective function is secured. 'Ihis also serves to prevent the asphalt appearing or showing through at the indented areas. In this way, the asphalt layer 8 is substantially completely obscured throughout its extent on the shingle and the shingle presents substantially the same colored appearance in the indentations as in the major area or non-indented portions of the shingle and,

moreover, no substantial shadow effect is produced by the shallow sloping-sided indentations. Also, as before pointed out, the difference in relief is not readily apparent and the visual effect of said indentations is that of a texture or design in or close to the surface plane rather than an indented one. Though the preferred form of shingle of this invention is of plain color, variegated or mottled colors may be employed to advantage in the practice of the invention, particularly as to its use in connection with roofs. V.Having described my invention what I wish to claim and secure by Lettersl Patent is:

1.' In an ornamental shingle of the class described, an asphalt-saturated felt base, a lower layer of asphalt on one surface of said base, a uniform layer of mineral particles attached to said layer of asphalt, a second layer of asphalt superimposed upon said layer of mineral particles and embedding the same between the said lower and second layers of asphalt, an exposed uniform layer of mineral particles upon the surface of said second layer of asphalt, said lshingle having a design of shallow lines indented therein and under the indented areas of which thel two layers of mineral particles are pressed more close- 1y adjacent than in the non-indented areas of said shingle with the said exposed layer spaced throughout its extent from said base by the underlying layers of asphalt and the embedded layer of mineral particles.

2. In an ornamental shingle' of the class described, an asphalt-saturated felt base, a lower layer of asphalt on one surface of said base, a uniform layer of mineral particles attached to said layer of asphalt. a second layer of asphalt -superimposed upon said layer of mineral par` ticles andembedding the same between the said lower and second layers of asphaltlan exposed uniform layer of mineral particles uponfthesurface of said second layer of asphalt, said shingle having an irregular design of shallow sloping sided indentations and under the indented areas of which the two layers ofmineral particles are pressed more closely adjacent than in the non indentedareas of said shingle with the said exposed layer spaced throughout its extent from said base by the underlying layers of asphalt and theiembedded-layer of mineral particles.

'3. In anornamental shingle of the class described, an asphalt-saturated felt base, a lower layer of asphalt on one surface oi' said base, a

uniform layer of mineral particles attached to said layer of asphalt, a second layer of asphalt superimposed upon said layer of mineral par-v ticles and embedding the same between the said lower and second layers of asphalt, an exposed uniform layer of mineral particles upon the surface of said second layer of asphalt, said shingle having an all-over irregular design of shallow sloping sided indentations. and under the indented areas of which the two layers of mineral particles are pressed more closely adjacent than in the non-indented' areas of said shingle with the said exposed" layer spaced throughout its extent from said hase by the underlying layers of asphalt and the embedded layer of mineral particles.

4. In an ornamental shingle of the class described, an asphalt-saturated felt base, a lower layer of asphalt on one surface of said base, a uniform'layer of mineral particles attached to said layer of asphalt, a second layer of asphalt superimposed upon said'layer of mineral particles and embedding the samebetween the said lower and second layers of" asphalt, an exposed uniform layer of mineral particles upon the surface of said second layer of asphalt, said shingle having an all-over irregular design of shallow sloping sided indentations simulating the grained textured appearance of weathered woodenishingles, and under the indented areas of which the two layers of mineral particles are pressed more closely adjacent than in the non-indented areas of said shingle with the said exposed layer spaced throughout its extent from said base by the underlying layers of asphalt and the embedded layer of mineral particles.
