ROOFING FABRIC.
Specification of Letters Patent. i Patented June 13, 1916,
Application filed January 11, 1916. Serial No. 71,502.
To all whom t may concern Be it. known that I, BENJAMIN G. CASLER, a citizen of the United States, residing at Tonawanda, in the county of Erie and State of New York, have invented certain new and useful Improvements in Roofing Fabrics; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates tothe manufacture of that class of roofing fabrics vcommonly termed smooth surface or rubber finished roofing fabric, in contradistinction to roofing fabrics having a grit, sand, gravel or like wear or outer surface.
I-Ieretofore in the manufacture of smooth surfaced or rubber finished roofing fabrics it has been the practice to apply the hard asphaltum outer or Wear surface directly lto the saturated body fabric and in order to obtain the required -thickness and fleXibility in the finished product it has lbeen necessary to make use of a thick high-priced felt body fabric, and even under such careful conditions of manufacture the resultant product has often been found to lack in service the necessary tensile strength, pliability and durability as a result of the transference of the oily matter from the body fabric to the wear surface whereby the body fabric is in time rendered dry, brittle and less pliable and the outer or Wear surface is softened and rendered less resistant of'wear.-l A
It is the object of my present inventionto overcome the above noted objectionable conditions arising from the present method of manufacturing smooth surfaced roofing fabric and thereby to enable the manufacturer to substitute a light-weight, inexpenslveI body fabric for the commonly used heavyweightghigh-priced felt body fabric and still obtain the required thickness in the finished product; and also to enhance and maintain the tensile strength, fiexibility and durability of the finished product.
To this end my invention, broadly stated, involves the interposition between the saturated body fabric and the hard asphaltum outer coating of a roofing fabric, of an intermediate laminated layer or septum of a substance of a character adapted to impede or prevent the transference of oily matter from the saturated body fabric to the hard asphaltum outer or wear surface of the fabric, and a roofing fabric having such a formation embodies the main feature of my invention.
While the substance which constitutes the interposed layer on septum to impede or prevent the transference of the oily matter from the body fabric to the wear surface may be a miner al or metallic substance, as-
bestos fiber or the like, yet by preference I employ for this purpose a substance having a laminated structure or a basal cleavage which when crushed produces thin, tough laminee or scale, as for instance mica, which will when properly applied produce a surface formed of overlapping scales, as the samev adds greatly to the tensile strength and durability of the finished roofing v fabric* Without 'detracting from its pliability or flexibility; and the employment of micaceous matters for the interposed layer or septum to impede or prevent the transference of oily matterv from the body fabric to the hard asphaltum wear surface of a roofing fabric embodies a secondary feature of my invention.
In the drawings chosen for the purpose of illustrating my invention, Figure l is a plan View of a roofing fabric embodying my invention, parts being broken away to show the relation of the interposed impedingseptum to the saturated body fabric and the outer or hard asphaltum coating of the roofing fabric. Fig. 2 is a sectional view of the roo-fing fabric shown in Fig. 1.
Like symbols refer to like parts wherever they occur.
I will now proceed to describe my invention more fully so that others skilled in the art to which it appertains may apply the same.
In the drawings, 1 indicates the body fabric which may be of any suitable material but is preferably a light-weight single ply lfelt fabric; 2 indicates a thin coating of asply felt fabric, Which is to constitute the body fabric 1 of the finished roofing fabric,
ished product of the required thickness. To
the body fabric l havingthe coating 2 of soft asphaltum and the micaceous coating 3, is finally applied a surfacing of hard asphaltum which constitutes the outer coat or Wear surface of finished roo-fing fabric.
The several steps of the above noted process of manufacture may, bv a suitable arrangement of kettles or tanks and rolls, which Will at once suggest itself to a person skilled in the art, be consecutively and continuously performed, or if preferred may be interrupted after the application of the micaceous layer 3 to the body fabric l, and the rooiing fabric subsequently finished by the application of the outer or Wear coating 4, at the will of the operator.
Having thus described my invention, What I claim and desire to secure by Letters Patent is:
1. A roofing fabric comprised of a satun rated body fabric, an outer coating of hard asphaltum, and an intermediate laminated layer or septum adapted to impede or obstruct the passage of oily matter from the body fabric to .the hard asphaltum outer coating.
2. A roofing fabric comprised of a saturated body fabric having a coating of soft asphaltum or asphaltum cement, an outer coating of hard asphaltum, and an intermediate laminated layer or septum adapted to impede or obstruct the passage of oily matter from the body fabric to the hard asphaltum outer coating.
3. A roofing fabric comprised of a saturated body fabric, an outer coating of hard asphaltum, and an intermediate micaceous layer or septum adapted to impede or obstruct the passage of oily matter from the body fabric to the hard asphaltum outer coating.
4. A roofing fabric comprised of a centrally disposed saturated body fabric, a coating-of soft asphaltum or asphaltum cement on the opposite surfaces of the saturated body fabric, outer coatings of hard asphaltum on both sides of the roofing fabric, and micaceous layers or septa interposed between the soft asphaltum coatings of the body fabric and the exterior coatings of hard asphaltum.
In testimony whereof I aHiX my signature.
