TUBULAR FABRIC AND THE METHOD OF WEAVING THE SAME.

SPECIFICATION forming part of Letters Patent No. 244,395, dated July 19, 1881.

Application filed June 24, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. LORD, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Tubular Fabrics and the Method of Weaving the same; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,forming partof this specification.

The object of this invention is to facilitate the weaving of tubular fabrics and reduce their cost; and the invention consists in a tubularwoven fabric composed of two faces united at their ed ges by their weft-threads carried around extra edge warp-threads, with or without a lin ing, as of rubber, incorporated in the fabric in the process of weaving.

The-invention further consists in the method of weavingtubular fabrics, the same consisting in separately interweaving the weft or filling threads with the warps of the two sides and uniting the said sides by passing the said weftthreads at each edge around one or more binding warp-threads, as hereinafter specified and claimed.

Figure l is. a perspective View of such parts of a loom as are most essential in producing the tubular fabric referred to. Fig. 2 is a sectional view, showing the lay of the weft or fillin g thread in single-ply tubular fabric woven with two shuttles. Fig. 3 is a view of the fabric. Fig. 4 is a diagram showing the position of the beams for the warp, the extra warp forming the edge, and the beam for the lining, as also one position of the harnesses. Fig. 5 is a diagram showing the harnesses in the opposite position to that shown in Fig. 4. Fig. 6 is a partial view of the lay, showing the manner of operating the two shuttles; and Fig. 7 is a sectional' view of the lay through the line a at, Fig. 6.

In practicing my invention I make use of any approved form of loom; but the construction illustrated in the accompanying drawings is the one I prefer, and I will proceed to describe such construction in detail forrthe clear understanding of my invention.

a represents the beamon which the interior lining for the tubular fabric is wound, and from which the same is delivered so as to bewoven into the fabric. 1) is the usual warp-beam.

c is the warp-beam on which the preferably heavier warp-threads for forming the edges are wound.

ddrepresentthcharnesses,four being shown as required for a single-ply tubular fabric.

. 6 represents the lining, which may be of rub her or of any other material suitable for the purpose for which the tubular fabric is to be used. This lining is passed between the wires or lines of the harnesses in a flat condition, and is supported in the central position by means of one or more eyes or oblong loops supported by the wires or cords e, the lining maintaining a fixed vertical position and being taken up with the fabric. When a hydraulic hose is to be woven the rubber lining is thus woven into the fabric and, being of soft rubber, can be readily secured and vulcanized by forcing steam into the interior tube, as is now usually done. The insertion of the light rubberlining into great lengths of tubular fabric after they are woven, which requires considerable time and skill, is avoided by this improved method.

The improved tubular fabric is woven with two shuttles, one laying the weft or filling for one half of the fabric, and the other the weft or filling for the other half, as is shown in Fig. 2, in which f frepresent the weft-yarn for one side, and f f the weft-yarn for the opposite side of the tubular fabric. 9 g are the edge warp-threads, by which the wefts of the two sides, each laid by a separate shuttle, are united. These warp-threads are preferably made stronger th an therest of the warp-threads, or two or more warp-threads may be used to unite the weft-threads. By this arrangement either the weft or the warp, or both, used for one side may be of a different kind of yarn, in color as well as in the material, from that on the other side 5 and such a fabric may be used for girdles, neckties, or other articles. One side may be silk and the other of cotton, either in part or whole, or one side may be of one color and the. opposite side of another color. The fabric may be Woven of a single ply, or of two or more plies, with or without an interior lining. v

The shuttles are operated by means of racks and pinions, and any number of sets of shuttles may be operated at the same time, so that four, six, or eight lengths of this fabric may be woven at the same time in one loom. I

h h, Fig. 6, are racks sliding in ways on the lay. They may be reciprocated in anydesired manner, one manner being shown in the drawings, in which t is a gear-wheel operated by a chain from the levers t" i, which are actuated by the cams i 41 so that by the alternate depression of the levers i t" the gear 2' receives an alternate partial rotation, whereby the rackbars h h are reciprocated alternately in opposite directions. The rack-bars h h operate the pinions h h, the axles of which are fixed, and

through the same propel the shuttles k alternately in opposite directions, as the gear 4. is alternately turned in opposite directions.

The shuttles are provided with toothed racks, and are thus carried through the open shed to lay the filling between the warp-threads, as is clearly shown in Fig. 6.

k is the breast-beam of the loom, and l the woven fabric. The harnesses and other moving parts in this loom are operated in the usual manner.

The shuttles are operated, as described, by positive motion through the racks and pinions.

The laysin looms have heretofore been made of wood, and since lays provided with reciprocating racks and with pinions to operate the shuttles, as shown in Figs. 1, 6, and 7, would be liable to warp and wear, I prefer to construct the ways of metal, and secure the same to the lay-swords by bolts.

A A are the metal ways provided with the flanges or projections B B, by which the same are secured by means of bolts to the layswords. They are also provided with bearings for the pinions h h, and, not being liable to warp, the reciprocating racks h k can be more readily operated and require also less power, as the surfaces can be more accurately fitted.

Having thus described myinvention,I claim as new and desire to secure by Letters Patent- 1. A tubular-woven fabric composed of two faces united at their edges by their weftthreads carried around extra edge warpthreads, substantially as described.

2. The method of weaving tubular fabrics, the same consisting in separately interweaving the weft or filling threads with the warps of the two sides, and uniting the said sides by passing the said weft-threads at each edge around one or more binding warp-threads, substantially as described.

3. A tubular-woven lined fabric in which the lining is incased by weft-threads laid on opposite sides thereof about binding edge warp-threads, substantially as described.
