BENJAMIN L. STOWE, OF BROOKLYN, ASSIGNOR TO J. VAN D. REED, OF NEW YORK, N. Y.

TUBULAR-WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 486,621, dated November 22, 1892.

Application filed December 1t: 1884. Renewed January 18, 1890- Serial No. 337.385. (No model.)

To all whom it wmy concern:

Be it known that I, BENJAMIN L. STOWE, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Tubular-VVoven Fabric Hose for Hydraulic and other Purposes, of which the following is a specification.

Woven or knit hose as hitherto usually constructed has required a rubber lining in order to be made water-tight.

It is the main object of my improvement to dispense with the rubber lining and still to obtain a fabric hose which shall be watertight. This end I find can be attained by producing a fabric tube of linen or analogous material that shall be nearly or quite watertight under hydraulic pressure, which can readily be done by weaving or knitting the fabric of a sufficiently-close texture and then drawing, weaving, knitting, or braiding about the said tube another tube of cotton or other similar material. The inner linen tube is practically watertight. The outer cotton tube is neither air-tight nor water-tight. The latter gives strength and body to the hose, while at the same time it permits the inner tube after it has been wet to dry thoroughly and rapidly. Hose thus made is quite as effective for hydraulic purposes as the rubberlined fabric hose now used for the same purposes.

The accompanying drawings represent woven hose embodying my improvement.

The parts are represented on an exaggerated scale with the strands separated from one another, so that the construction may be more plainly seen. In the actual hose the strands are of course closely packed together.

Figure 1 is a cross-section of the hose, repsenting a few only of the warps of the inner and outer tubes. Fig. 2 is a longitudinal central section of the hose. Fig. 3 is a view of the exterior of the hose with the outer tube broken away so as to expose the inner one. In the hose shown in these figures the two plies or thicknesses are not shown as bound together to make one fabric. Fig. 4 is a crosssection, and Fig. 5 is a longitudinal central section, of hose in which the plies are bound together.

A is the inner linen tube. It is a woven tube of such close texture as to be nearly or quite water-tight under hydraulic pressure.

B is the outer surrounding tube, also woven, of cotton or other similar material.

In Figs. 4 and 5 the two plies A and B are bound together by binder-warps 0, introduced into the fabric during the process of manufacturing it. More than two plies of hose may be assembled together, the inner one being tight and the outer ones loose; but it is not generally desirable to do so. In a fabric hose of this description if a weft in part of wire be used in weaving the inner tube or ply, the hose may be used for suction purposes. In cases where the hose is used in short lengths and is so distended as to permit of a free circulation of air through it when it is not in use, the inner ply which possesses the wire weft need not of necessity be the water-tight one. It will be sufficient if the ply surrounding it be so instead.

I do not here broadly claim a tubular fabric possessing the characteristics herein set forth, for the same, among otherthings, is the subject of my application for Letters Patent of even date herewith, bearing Serial No. 150,429, renewed January 18, 1890, Serial No. 337,37 8.

Having described my improvement, what I claim as new and of my own invention is 1. A compound tubular-fabric hose, consisting ofa closely woven or knitted and practically-water-tight tube of linen surrounded by one or more loose-textured cotton-fabric tubes to give strength and body to the hose and at a
