IMPROVEMENT IN FIRE-HOSE.

Specilication forming part of Letters Patent No. 161,273,

dated March '23, 1875 reissue No. 7,442, dated Dension A;

To al? whom it 4may concern:

Be it known that I, JOHN VAN DUssEN REED, ot' the city ot' New York, county and State ot' New York, have invented a new manufacture, consisting ot' Improved Woven Hose for tire. hydraulic, and other purposes` ot' which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

Figure l is a cross-section of my new hose, constituted ot' more than asingle ply. Fig.2 i is a longitudinal section ot' the same. Fig. 3 is a similar view ot' one of the practicable modiiications oi' the texture of my hose. Fig. 4 is a sectional View ot' a loom in which, with certain moditications and additions herein described, my new hose maybe Woven.

y invention relates to a multiply, fire, or hydraulic hose, composed of cotton, linen, or i other equivalent material, which, being woven in a cylindrical or equivalent form. without abrupt bends in the weft-strands, in contradistinction to being woven in two dat sheds, i with the woot-strands sharply curved where l they pass trom the one shed around into the other. and the woot-strands' being closely pnched into the web, is of substantially uniform appearance and strength throughout.

The d rn wings represent several sections of my three-ply hose,Fig. 1 being a cross section, and Fig. :l a longitudinal section. Fig. 3 is' also a longitudinal section oi' a three-ply bose, showing a modification in which each and all i the warp-threads pass baci; and forth through the entire thickness ofthe web.

ln Fig. 1 the large circles represent the woot-threads of a threeply hose, and the small circlesl the ends of the warp-threads.

Llach woot-thread and its adjacent Warpthre-.ids constitute, in i'act, a distinct web, and then the said three webs are tied together by certain strands a of the warp, represented by full lines in Fig. 2 and Fig. 3, which pass through the web from face to face between and crossing the woot-threads.

1n order that those skilled in the art may be able to Jfabricate my new hose, whetheri two, three o1` more ply, 1 will describe a method. and a loom, by which it may be pro- 5. duced. not l imiting myself, however, to any i,

special method or i",strumentality, my claim 'i in this gpeewnuvlbdlg for the product it self as a new manufacture.

On the L1th day of June, 187 2, Letters Patent of the United States were reissued to me for improvement in looms for weaving hats. I have employed said loom, with certain moditications, changes, arTd additions,in the weaving ot' my new hose of more than one ply. The general description of that loom I shall not here repeat, but refer thereto for the same, confining my present description to the changes and additions necessary for the production of my new hose.

ln order that these changes and additions may be the more readily understood, l have reproduced here inFig. 4 of the drawings a sectional view oi' the parts of the said loom by which the Warp strands or threads are carried, and the Woof-thread delivered into the web and packed therein, with the above-named necessary additions and changes.

In this loom the warpstrands are held on spools carried by jacks, arranged around a circle, the strands converging toward the center oi' the circle, where they pass down through a hollow cylinder over the upper circularedge of the said cylinder. Just at this edge the Woof-strands are woven into the warp by a shuttle, which is carried around the circle and winds the Woot' into the web spirally, thus forming a continuons cylindrical tube.

The ends ofthe warp-threads before the operation oi weaving in the woot is commenced are gathered together, carried down through the cylinder A, Fig. 4, around under the drum B, over the drum C, and back around a drum or axle, D. By a stress oi' a weight or spring upon the axle D, the proper strain is given to the warp-threads.

Upon the shafts c c oi' the drums B C are gears, which are driven by the worin E', to which motion is communicated from the driving-pulley F through the shaft and gears 1,2, 3, 4, 5, (i, and T, and the. worm and gear S and 9.

The warp-carriers or jacks a are held between verticnl guide-plates or partitions, and are caused to more up and down in their places between said guide-plates bythe harness to gire the requisite motion to the warpstlands in the act of weaving, the shuttle be' BEST AVAILABLE COPY ing carried in the end of the arm E, which is attached to the frame carrying the harness, and revolves with it, thus winding the said woot-'thread into the web spirally and continuorsly from end to end ot the hose, all of which, so far as relates to the action ot' the wootcarriers and shuttle. is fully described in the Letters Patent bel'ore referred to.

Now, to produce a double-ply web, a second shuttle and shuttle carrying arm are provided, the said arm heilig attached to the, revolving carriage or rings ot" the loom, the two arms being placed at opposite sides ot' the loom. each shuttle carrying a separate wootthread. A certa-in number ot' the jacks or warp-carriers are made to. carry the threads, to form one of the ply, and an equal number to carry those to forln the other ply. The warp-threads for each web Iare thrown by their carriers to form, with the woot-thread delivered from the shuttle, respectively, a separate web, and then the two webs are tied together into one by another set of' the warp-threads, which cross through both webs, back and forth, aroundl the two woot-threads, the jacks carrying these tying threads heilig, by the direction of the guide-rings ofthe harness which actua-te them, made to thus` pass .back and forth through the entire thickness of both webs. Usually about every fourth warpstrand is made such tyingstrand .A greater or less number may be used at pleasure.

The operation described will produce a fabric the relative position and direction of the several threads of which are represented by the Figsi and 2, the former being a crosssection ot' the hose, and the latter a longitudinal section. These drawings are made on a greatly enlarged scale, and the strandsor threads are represented as separated widely from each other in order that their relative position and direction may be plainly seen.

ln the actual web, the strands are ot' course crowded into close contact with each other. To do this l attach at essentially right angles to the end of the shuttle-carrying arm a di vider consisting of two arms, e e, formed into au oblate frame. The shuttle travels between the arms ci' the divider, and delivers the weft evenly and closely' between the warp-strands, which are forced apart in its passage, and these warp-strands being closed after the passage of the divider, tie the weft up solidly and tirm, and it is further compacted b5' the next passage ot the shuttle and divider.

I do not intend to limit myself' to the precise arrangements of the threads described. Another arrangement of the threads is shown in Fig. 3. Any equivalent arrangement may be adopted by which there is produced a tube of the form herein described of several plies tied together into one web. Any mechanic or weaver skilled in the art will know how to adaptthe said loom to accomplish such equiv aient arrangements of the threads.

To make a three-ply hose, (the one represented in the drawings,) it is only necessary to add a third-shuttle and shuttle carrier, divide the warp-threads into three sets beside the tying-strands, one set for each web, and construct and arrange the harness to throw the carriers ot' the several sets to weave with the three Woof strands three separate webs, and then to cause the tyingstrands to pass through the three Webs and bind them together, or to cause all the warp-threads to cross and recross entirely through the three webs, as seen in Fig. 3.

There are, I believe, novel and patentable devices and combinations above indicated not found in the loom already secured to me by the Letters Patent referred to, and which are necessaryon the loom described tor the wearing of more than a single ply, which Ido not intend to claim in this specification, intending to reserve the same for a separate application for a patent, which it is my purpose to make.

I here claim as a new manufacture- Fire or hydraulic hose of more than one ply, composed ot' cotton, linen, or other analogous material, woven whole in a cylindrical or expanded form, with two or more weft-threads interwound and packed with the woot-threads in concentric helical coils, one within another, and without any short bends, thus possessing, substantially, uniform strength and a uniform appearance around its entire body, substantially as described.

Witness my hand this 25th day of October, 1876.

JOHN VAN DUSSEN REED.
