To all whom it may concern:

JOHN MURPHY, on BROOKLYN, New YORK.

`":ePl!CIEIC'A'ZIZION forming part of Letters Patent No. 296,436, dateduApi-il 8, 1884.

Application tiled January 21, 1E84. (No model.) i

Be it known that I, JOHN MURPHY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of N ew York, have invented certain new and useful Improvements in Hose, of which the following is a specification, reference being had therein to the accompanying drawings.

Heretofore hose generally, and `especially firehose, has been made up of an interior and exterior layer of rubber, with generally a number of thicknesses of cotton duck interposed between the two layers of rubber, the thickness of duck being cemented to the layers of rubber and tol each other by a rubber cement, and the whole being subsequently vulcanized. It has been customary by some manufacturers to cut the duck which is used fri" this'purpose on thevbias, and by other manufacturers it has been'customary to cut the duck straight and not on the bias; but both of these methods have serious objections in y use. "When the duck is-cut on the bias, the

tendency of the hose, When subjected to press ure, is to increase in diameter and decrease in length, because there is no ufabric which coni tains fibers running in such direction as to directly oppose the radial strain due to the: pressure. On the other hand, when the duck hasl been cut straight and not on the bias, the

objection has been that where a sudden turn or bend was made in the hose in use thestrain brought upon the longitudinal ibers of the duck was so great as to cause them to break vand injure the hose.

` The object of my invention is to construct a hose which will not be open to either of these obj ectionsmthat is to say, in use it will neither be caused to expand by pressure from within to any practical extent, and atthe same time will not be liable to break `when subjected to turns or short bends.

My invention consists in interposing between the two thicknesses of rubber which coat the hose on its interior and exterior two or more thicknesses of cottonl duck, one or more of said thicknesses being cut on the bias and placed next or near the the exterior cov ering of rubber,and one or more of said thicknesses being cut straight and not on the bias, and being placed he thickness or thick-y nesses which are cut on the bias. The inten rior thickness or thicknesses of cotton duck contain fibers which run circumferentially around the hose, and 'thus present a direct re! sistance against radial strain from within, while at the same time the duck which is outside of the same and cut on the bias does not present fibers ruiming longitudinally of the hose in such manner as to be liable to break by bending or short turns.

In thedrawings, Figure l shows aside view of a short piece of my hose, with its various layers of duck and exterior rubber removed sufiiciently to show the general construction of each. Fig. 2 shows a piece ofthe duck cut on the bias, and Fig. 3 a piece cut straight.

i At a is shown the exterior coating of rub ber, ofthe usualthickness commonly employed ytion, asindicated in Fig. l.

At c is shown the next thickness of cotton duck, and this also is cut on the bias, so that its fibers run around the hose in a spiral direction, as indicated.

At d is shown the next thickness of ducky toward the center, and this thickness,unlike the two external thicknesses, is not cut on the bias, but is cut straight, as shownin Fig. 3, so that its bers, instead yof running around the hose in aspiral direction, run in planes nearly or quite longitudinal with vand at right angles to the axis of the hose.

At e is shown the next thickness of duck toward the center, and this, like the thickness d, is not out on the bia-s, but has its ibers running in planes nearly or quite longitudinal with and at right angles to the axis of the hose.

Atf is indicated the internal thickness of rubber, which serves as the lining of the hose. These various thicknesses of rubber and canvas are put together in the usual manner (preferably breaking joints)-,and vulcanized.

I do not limit myself to the exact angle at which the ibers of the external thickness or thicknesses of duck run, the object being to have them at a suiiicient angle to prevent any IOO direct strain being brought upon the fibers by l I make no claim to the structures shown and a sudden twist or turn in the hose; nor do I limit myself to having the bers of the interior thickness of fabric run exactly in the directions indicated, the object being to have them run sufficiently near in that direction to substantially oppose the tendency to radial expansion by the direct or nearly direct strain upon the fibers ruiming around the hose.

. I do notlimit myself to the number of thicknesses of the textile fabric employed, providing there may be more than one thickness, so that there can be both a thickness of fabric cut on the bia-s and a thickness not cut on the bias, nor do I limit myself to the proportion l the bias.

described in the Letters Patent No. 184,907, granted to T. L. Reed, November 28, 1876, and No. 164,946, granted to J. M. Stone, June 29, 1.875. f

l. As an article of manufacture, a hose containing an interior and exterior layer of rubber, and interposed between said layers of rubber a textile fabric cut straight, surrounded by a textile fabric cut on the bias, substantially as set forth.

2. In a hose, the combination, with atextile fabric cut straight, of a textile fabric cut 0n the bias and so arranged that the textile fabric cut on the bias is outside of the textile fabric cut straight, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN MURPHY.
