LOOM FOR WEAVING TUBULA R FABRICS.

SPECIFICATION forming part of Letters Patent No. 223,534, dated January 13, 1880. Application filed April 10, 1878.

To all whom it may concern Be it known that I, ADDIE M. Four, of Warwick, in the county of Orange and State of New York, have invented certain new and useful Improvements in Looms for Weaving Tubular Fabrics, of which the following is a specification.

My invention relates particularly to looms for weaving tubular fabrics, and especially 1o fire-hose; and one feature consists in employing in a loom, in connection with the reed,a former which is impelled with the reed to the fabric being woven, and maintains the latter at a uniform size. The invention also consists in anovel mechanism for shifting a shuttle or shuttles from one to another of two sheds; also, in other combinations of parts hereinafter described and claimed.

'In the accompanying drawings, Figure 1 is a transverse section of a loom embodying my invention, taken just in front of the shuttle boxes and lay. Fig. 2 is a transverse section of a reed, and also a top view of the former and its bridge-piece of such loom; and Fig. 3 is acentral longitudinal section of the entire loom.

Similar letters of reference designate corresponding parts in all the figures.

A designates the frame of the loom. B designates bars forming part of the frame, and serving to sustain and guide

shuttles

8 and 9 as they pass into and through the two sheds G G formed by double-eyed leaves of heddles H. O designates the lay, and D the reed, which maybe of any desirable construc tion.

0 and N are trough-shaped shuttle-boxes, having overhanging ledges for receiving and holdingbase-plates with which the

shuttles

8 and 9 are provided. These shuttle-boxes are mountedupon endless belts or chains working over pulleys It and R and R and R on the shafts R, in close proximity to the sides of the lay, and they carry the shuttles from one shed to the other.

F designates a former, (here shown as consisting of a wedge-shaped device,) which may be made of metal, and is, in this instance, ar- 0 ranged across and projects from the face of the reed near the center of the latter. It may be provided with a bridge-piece (see Fig. 2) extending across the frame of the reed, and may be perforated to receive the dents of the reed through it to insure its stability.

I designates a warp-beam, which can be of any suitable form, and operated in the usual way. I and 1 are rollers or guides, overeach of which a portion of the warp-threads is carried. Each portion of warp-threads passes thence to the eyes of the appropriate heddles H. The threads passing around the lower roller or guide, I, pass through the lower eyes in the heddles and through the spaces between the dents of reeds D which are below the former F, and the threads passing around the upper roller or guide, I", pass through the upper holes in the heddles and through the spaces between the dents of the reed D which are above the former F. The upper and lower portions of the warp-threads are separated permanently by the former F and its bridge, as also by the double-eyed heddles H, and the two sheds G G one on each side of the former F, are produced.

Any number of leaves of heddles may be used, and the warp-threads can be drawn in so as to weave any desirable figure, care being taken to have the last threads of one portion properly correspond with the first threads of the other portion, so that when the edges of the two divisions of warp are drawn together by the weft the figure shall be perfectly matched.

The leaves of heddles H may be operated by treadles moved by the foot of the weaver, or by levers 1 and 2, actuated by cams upon a suitable shaft, when the loom is dziven by mechanical power. I

I prefer to have at least one dent of the reed 5 beyond the edges of the former at each side, as shown in the enlarged view, Fig. 2, and the former F, besides being made wedge-shaped upon all its sides and edges, is preferably of slightly oval form transversely and rounded at the outer end. When the former is thus shaped it can be the more easily pressed into the woven or partly-woven tube and withdrawn therefrom at each stroke or pick of the lay.

The shuttle-boxes 0 and N are so arranged relatively to each other upon their endless belts that one of the boxes, 0, comes opposite one of the open sheds, and one of the boxes, N, simultaneously comes opposite the other shed, whereupon the shuttle 8 can be passed across the reeds above the former F into the box N, and the shuttle 9 can at the same time be passed across the reeds in the opposite direction below the former F and into the box 0. The reed is then carried forward and the weft beaten up in the fabric, as is usual, after which the lay returns to its normal place.

The leaves of heddles having been shifted, new sheds are formed at the same time, and the

shuttles

8 and 9 having been carried transversely in different directions, as indicated by the arrows, to positions opposite the other sheds, each shuttle passes through one shed in one direction and returns through the other shed in the opposite direction.

The shuttles maybe impelled through the sheds by the hand of the weaver, or, when the loom is run by mechanical power, by pickerstaffs K, one upon each side of the loom,- and operated simultaneously by cords a, attached to a lever, which is actuated by a cam, E.

The shuttle-boxes and their belts are always respectively moved in the same direction, each set, however, in the opposite direction to the other.

An intermittent motion is imparted to the belt by pawls 0, carried by levers c, and actuating ratchet-wheels P P on the lower shafts, 1t R,-for the said belts, and when the loom is driven by mechanical power these levers 0 may be connected with the lay by cords s s, passing around pulleys t t, attached to the loom-frame in such manner that when the lay is moved forward the said levers may be shifted to cause the pawls to impart motion to the ratchet-wheels and the belts, and thus change the position of the shuttles. In lieu of this, however, special cams can be put on the 'main shaft of the loom, or other means applied, as may be desired.

The fabric, after being woven, can be wound on a beam, or otherwise taken care of in various ways well known to those skilled in the art.

Having described all the features of my loom, it is only necessary to explain that the tension of the weft in passingfrom the shuttles must be sufficient to pull the two edges of the two separate portions of warp together as it is wound around and bound into the warp by the course pursued by the shuttles, while at the same time the continual entering and withdrawing of the former F keeps the size of the tube uniform and aids to distribute the warp evenly at the edges or selvages.

I do not wish to confinemyself to the entire combination as shown, or to the exact arrangement of parts, as it is obvious that many changes can be madea-s, for example, plain, single-eyed heddles can be used by adding other leaves of heddles, and perhaps, for some kinds of work, the former can be dispensed with. Q

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a loom, of a reed and a former, the latter mounted on the reed, and suitable mechanism for operating said parts, substantially as specified.

2. The combination, in a loom,.of a reed and aformer impelled with the reed to the fabric being woven, and suitable mechanism for operating said parts, substantially as specified. v

3. The combination, in a loom, of a reed, a former borne upon the same, and a bridgepiece extending transversely across the frame of the reed and receiving the dents of the reed through it, substantially as and for the purpose specified.

4. The combination of the reed Dand former F, said former being securely mounted upon the face of the reed and dividing the warp permanently in two separate parts, substantially as specified, and for the purpose set forth. f

5. The combination, with the shuttle-carriers O N, mounted on endless belts, and mechanism, substantially as herein described,

for operating them for carrying the shuttles from the position of leaving one shed or opening of the warp to another position opposite another shed or opening of the warp, each one always pursuing its own direction for the purpose of winding the weft around a portion of the warp, and thereby weaving a tube, substantially as set forth.

6. The combination of mechanism for formin g the two distinct sheds G G with the former F and reed D, said former being permanently secured to the face'of the reed, and having the reed extending each side of it, and the shuttle-carriers O and N, substantially as specified, and for the purpose set forth.
