PREPARED ROOFING Filed Sept. 26, 1921 IN VEN TOR ATTbRNEY Patented Mar. 17, 193] PATENT- OFFICE GEORGE D. GRABIBS, F CINCINNATI, OHIO mar nara) ROOFING Application filed September 26, 1921. Serial No.503,854.
' My invention relates to prepared roofing, such as shingles, made with a flexible base saturated with and coated with a bituminous material and surfaced with a layer of min- 5 eral particles. By my improvement I have obtained a prepared roofing which is more fire resistant, because it contains an amount of non-inflammable material greatly in excessof 50 per cent, than the prepared roofing heretofore on the market and not only has the advantage of being more fire resistant but also has the advanta e of being, when exposed to the weather, ess liable to curl.
In the preferred form of my invention shown in the drawing I provide a foundation A of feltor paper composed of a major portion of asbestos fibre, commonly known as XX fibre, and a minor proportion of nonmineral fibre, preferably animal hair, of considerably greater length than the asbestos fibre. In making the foundation I prefer to use approximately 60 per cent XX fibre and 40 per cent animal hair. Any fibrous material of a suitable nature could be used in place of the-hair but I prefer that it be a fibre of a comparatively stiif nature. These materials are treated and formed into a paper or felt, in the ordinary manner of manufacture of felt. This felt is then saturated with a waterproof saturant, preferably a bitmuinous saturant such as asphalt after which the felt or paper is coated with a coating B of bituminous material preferably of a softer nature thanwthe saturant and into this coating is embedded slate, crushed asbestos rock, or other mineral granules or particles.
I-prefer to use for saturating my roofing, particularly in the manufacture of shingles a saturant of relatively hardasphalt having a penetration not exceeding 11 at 77 F. as determined by the Richardson &. Forest penetrometer, while for my coating I use an asphalt which is softer than the saturant. The combination of my fibrous felt with its relatively stiff fibres and the comparatively hard asphalt-saturant I have found enables me to make a shingle which has suflicient flexibility and likewise suflicient body to'make it substantially nou' curling. The employment any suitable surfacing material C such as for the coating material of'an asphalt softer than the asphalt which saturates the mineral felt provides a protective seal, over the foundation, which does not crack when exposed to the sun, as would the harder, saturating asphalt. This results in a considerable prolongation in the life of the roofing material-l Where mineral particles ,are applied to the base, the softer coating also serves to secure them in a place better than would be the case if they were applied to the hard saturating asphalt.
Claims: 7
1. In a prepared roofing a flexible founda tion, composed of a major proportion of mineral fibre, saturated with a relatively hard asphalt having a penetration not exceeding 11 at 77 F. J"
2. In a prepared roofing a flexible foundation, composed of a major proportion of mineral fibre, saturated with a relatively hard asphalt and coated with a softer asphalt.
3. In a prepared roofing a foundation, composed of asbestos fibres in excess of fifty per cent saturated with an asphalt having a penetration point "not in excessof 11 and coated with a relatively softer asphalt in I which is embedded a layer of mineral.
4. In a prepared roofing, a flexible fibrous foundation saturated with a relatively hard asphalt and coated with a softer asphalt.
5. In a prepared roofing, a flexible porous fibrous foundation, saturated with a relatively hard asphalt and coated witha softer asphalt. V
.6. In a prepared roofing, a flexible porous non-metallic foundation, saturated with a .relatively hard asphalt and coated with a softer asphalt in which is embedded a layer a of mineral.
7. In a prepared roofing,'aflat flexible fibrous foundation, saturated. with a relatively hard asphalt and coated with a softer asphalt in which is embedded .a layer of mineral. u
8. In a prepared roofing, a flexible felted porous foundation composed of a major proportion of mineral fiber saturated with a relatively hard asphalt and coated with-a softer asphalt, e
9. In a prepared roofing, a flat flexible porous foundation composed of a major proportion of mineral fiber saturated wlth a relatively hard asphalt and coated with a softer asphalt.
10. In a prepared roofing, a flat flexible porous foundation composed of a major proportion of mineral fiber saturated with a relatively hard asphalt having a penetration not exceeding 11 at 77 F. and coated with a softer asphalt in which is embedded a layer of mineral.
In testimony whereof, I have signed my name to this specification.
