SEAML'ESS MULTEPLY-FABRBC HOSE.

SPECIFICATION forming part of Letters Patent No. 299,018, dated May 20, 1884.

Application filed October 17, 1883.

.To all whom it may conceive:

Be it known that we, JUNIUs SOHENCK and BENJAMIN L. STow of Brooklyn, Kings ing is a specification.

Our invention is an improvement upon seamless multiply woven hose for fire, hydraulic, and other purposes, of the kind shown and described in Reissued Letters Patent No. 7,442, dated December 19, 1876; and it corn sists in the novel construction or combination of parts hereinafter fully set forth and claimed, whereby we enhance the capacity of this hose to resist tendency to elongation under heavy pressure, such as it is necessarily subjected to when used as fire hydraulic hose in connection with steam fire-engines.

The nature of our improvement, and the manner in which the same is or may be carried into effect, will be readily understood by reference to the accompanying drawings, in which- Figure 1 is a cross-Section of our improved hose, only one-half of the tube being represented. Fig. 2 is a longitudinal section on line 2 2,- Fig. 1.

In the actual web or fabric the strands are of course packed closely together. In the drawings, however, they are represented on enlarged scale, and as widely separated from one another, in order that the structure of the multiply fabric may be more plainly seen and understood. The seamless multiply tubularfabric which forms the body of the hose is in this instance a three-ply fabric, the warps and wefts of the two outer plies of which, as well as the tying-strands, are manipulated in the manner illustrated and described in Reissued Letters Patent No. 7,442. The warp strands of the outermost ply are lettered a, and the weft-strands b. The warpstrands of the intermediate or second ply are lettered c, and the weft-strands d. The tying strands,

which pass through the web from face to face, are lettered e. The inner or third ply of the web differs from the corresponding ply of the (No model.)

fabric hose described in said Reissued Letters Patent No. 7,442, in that the warp-strands 5o (lettered f) of this ply, instead of being interlocked or interwound with their weft, (lettered 9,) as in the other plies,are so manipulated as to lie straight and without material bend or corrugation between the second ply and the inner weft-threads, g, which latter are heldin position by the tying-strands e, the two being interwound or interwoven with one another in the manner described in said Reissued Letters Patent. The warp-strands f are preferably put under considerable tension during the weaving operation, so as to insure their being laid straight and without bend. Ve thus obtain a multiply seamless hose of the type described in said Reissued Letters Patent, which contains alayer of strai ght lon gitudinal'strands held in place between the inner weft and the next adjoining ply, and serving effectively to prevent any perceptible or material elongation of the hose.

Hose possessing the foregoing characteris tics can be readily manufactured by the method and apparatus set forth in the Reissued Letters Patent No. 7,442, with such modifications thereof required for the purpose as are within the knowledge of those skilled in the art to which our improvement relates.

The hose, after being woven,is provided with a rubber lining, h, applied to it in wellknown manner. Thislining,wheninplace,servesma- 8o tcriallyto assist in holding the innerweft and adjoining strands in place, thus fixing and holding the fabric and assuring the position of the longitudinal strands f.

In testimony whereof we have hereunto set ourhands this 1st day of September, A. D1883.
