-TUBULAR WOVEN FABRIC.
SPECIFICATION forming @met Letter; Patent Naciones, date september e, 189s. Application .filed J'uly25,1898. Serial No. 686,815. (No model.)
T0 a/ZZ whom it may concern:
Beit known that I, BENJAMIN `L. STOWE'," of Jersey City, in the State of New Jersey, have invented a new and useful Improvement in Tubular Woven Fabrics, of which the following is a speciication.
My present invention relates to woven fabric for hydraulic or fire hose provided with an interior surface free from the furrows or corrugations which appear on the interior surface of ordinary tubular woven fabric, thus furnishing a smooth surface upon which theV rubber lining can be laid. Y
In another application for Letters Patent, filed March 3l,`1898,"Serial= No. 675,885, on which Letters Patent will issue of even date herewith, I have Ydescribed and claimed a tubular woven hose fabricv in which the waterway is rendered smooth and free from corrugations by incorporating into the fabric leveling weft-strands, laid on the interior surface of the tubular fabric in the furrows or corrugations between the several filling-strands of are held in place in the fabric extend through to the exterior of the fabric. In my present improvement the warps which hold in place the said leveling strands do not extend through to the exterior of the fabric, but stop short of the outer ply thereof, the advantage of this improved arrangement being that the wearing away of the outer ply or plies will not destroy or impair the warps which hold the leveling filling or weft strands.
In the accompanying drawings, to which I shall now refer for a better understanding of my said improvement, Figure l represents in longitudinal section a piece of tubular-woven fabric rubber-lined hydraulic hose embodying my improvement. Fig. 2 is a longitudinal section of the fabric on a scale more en- Alargedthan inFig. 1.
In the drawings, and particularly in Fig. 2, the strands are represented on an enlarged scale and widely separated from one another inorder thatthe structure of the fabric may bemore. readilyunderstood. In the actual fabric the strands are of course packed closely together.
In Fig. 1 R is the rubber lining.
The fabric shown in the drawings is one which without the addition of the strands requisite to effectuate myimprovement would would be an ordinary multiply (in this instance three-ply) seamless hose, the three plies of which are lettered A, B, and C. The regular warp and weft of the inner ply are lettered a and b, respectively. The regular warp and weft of the intermediate ply are let tered d' and b', respectively. The regular warp and weft of the outer ply are lettered c2 and b2, respectively, and the bindingstrands which bind the plies together are lettered e.
In the fui-rows or corrugations between the filling-strands b of the inner ply and upon the interior surface of said ply I lay, during the process of weaving the fabric, an additional filling c, whichis held and incorporated into the fabric by warp d. The warp d and the filling c thus added to the fabric will 'preferably be of fine'yarn, just sufficient in size, when incorporated into the fabric, to fill the furrows between the ordinary lling yarn or yarns b on the interior` surface of the hose fabric, thus ,making this surface practically smooth and without corrngation. The strands CZ stop short of the exterior of the fabric and do not appear in the outer ply. Indeed they are in the illustration of my invention given in the drawings confined to the innermost ply A exclusively and do not appear in either the intermediate ply B or the outer ply C. The result of this improved arrangement of the warp-strands d is that they will not be destroyed or impaired by the wearing away of the outer ply or plies of the fabric.
I-Iaving described my improvement, I desire to state that I do not confine myself to the exact structural details shown in the accompanying drawings in illustration hereof; but i What I here claim, and desire to secure by Letters Patent, is
1. Tubular Woven fabric for fire `or hydrau lic hose having incorporated in its structure IOC) leveling weft-strands laid on the interior surface of the tubular fabric in the furrows between the usual filling-strands of said fabric, and Warp-strands for holding said levelingstrands which stop short of, and do not extend through to, the exterior of said fabric,
substantially as and for the purposes herein before set forth.
2. Tubular multiply Woven fabric for hydraulic or lire hose having incorporated in its structure leveling weft-strands laid on the interior surface of the inner ply in the furmy hand this 21st day of July, 1898.
