CLIFFORD IB. GRATZ, OF FLUSHING, NEW YORK, ASSIGNOR TO AMERICAN MANUFAC- TUBING COMPANY, or NEW YORK, N. Y.,

A CORPORATION OF MASSACHUSETTS.

HOSE.

Application filed September This invention relates to improvements in hose and, more particularly, to an improved fabric of composite character', having its weft and warp made of jute and cotton in tubular formation, and is usually used in combination with `rubber.` of my invention is the production of a` fabric composed of jute and cotton, wherein the inherent qualities of the jute will serve to retain the shape of said fabric.

A further object resides in the provision for intermingling the jute within the fabric to protect the same from the injurious effects of rough usage.

Another object is the production of a fabric relatively cheaper in manufacture yet admirably and suitably meeting the requirements of its several uses.

Further objects and advantages in my in# vention will become apparent as the description proceeds, and in order that the same may be better understood, reference ishadv to the accompanying drawing, forming part of this specification, wherein Figure l is a longitudinal central sectional view of my improved fabric, partly in elevation;` j

Figure 2 is a vertical cross-section there-k of; and

Figure 3 is a vertical sectional view showing a rubber tube in combination with the fabric.

In the drawings, the numeral 5 denotes generally any improved fabric, which is preferably woven in tubular formation and comprises a cotton Warp 6 and a jute Weft 7.

As shown in Figure 1, the jute 7 is disposed spirally within the fabric and completely covered by the cotton Warp 6.

Heretofore in the art, it has been the practice to use cotton or other more or less eX- pensive material for botlrthe warp and the weft, not realizing the advantage in a substitute for such a weft.

Observing that the use of a cotton weft causes changes in the dimensions of a fabric and quite often serious injury thereto, Ihave adopted as a substitute the use of jute, which is almost completely without shrinle` age or expansion and further possesses the advantage of being lower in price. Thus I am able to produce a fabric having an Primarily, the objectk vthis easily abraded material.

advantage'not possessed by the more expen- Itis, of course, manifest that my tubular fabric is admirably adapted for use as a covering for fire 'hose and other hose for delivering liquids under pressure.

Vhen used in this connection the strength ofthe fabric will be readily appreciated, since the high water pressure within the hose has little or no effect upon the jute weft and the usual stresses and strains put upon the present day cotton-covered hose are absorbed without disruption to the cotton warp of my improved fabric.

As shown in the drawings, particularly in Fig. l, the cotton strands are very tightly woven to afford full protection to the` jute 7, thereby affording ample protection for I do not wish to be limited to the foregoing details of construction.' As a modiication thereof, ysomeother material may be substituted for the cotton warp to cover and protect thejute strands. No doubt, instead of fibre, a plastic material may be substituted as a covering material for the jute,

in which case the latter would still perform its function of maintaining theshape of the hose.

Having described my invention, what I claim is l. A tubular fabric for hose ,comprising longitudinal strands and a. helical strand closely encased by` said longitudinal strands, said helical strand being composed of jute.

2. A tubular fabric for hose comprising longitudinal strands and a helical strand closely interwoven with and encased in saidV longitudinal strands, said helical strand being composed of jute to impart rigidity to the structure. Y Y

3. A tubular fabric for hose comprising longitudinal strands `and a helical strand composed of jute, saidV helical strand being encased in pliable mate-rial comprising said longitudinal, stra-nds.
