"To all whom it may concern.-

' Be it known that we, I-IALoYoN SKINNER and FRANK H. CONNOLLY, citizens of the United States, and residents of Yonkers, in the county of Westchester and State of New York, have jointly invented a new and useful Improvement in Needle-Loo1ns, of which the following is a specification.

Our invention relates to an improvement in 1o needlelooms, and has more particularly for its object to provide a loom with flexible wefty inserting needles, so that the needles may be wrapped around drums when withdrawn from the fabric being woven, whereby a great deal "i5 of lateral space is saved, and also whereby the needles may be employed on looms for l weaving wide fabrics Without taking up the lateral space, which hashitherto been necessary with the straight needles.

zo A further object is to provide a weft-inserting needle which will be flexible in one direction from a straight line and inflexible in other directions from a straight line, thereby doing away with any tendency on the part of the needle to buckle when it has been extended into the shed.

A practical embodiment of our invention is represented in the accompanying drawings, in which-- 3o Figure 1 represents in front elevation a portion of a loom-frame with two flexible weftinserting needles carried thereby and the mechanism for operating the same. Fig. 2 is a top plan View of the parts shown in Fig. 1. Fig. Sis a vertical section taken from front to rear through a portion of the loom. Fig. 4 is an enlarged detail side view of aportion of one of the flexible needles and its oscillating sprocket-wheel, a portion of the side plate 4o of `one of the links of the flexible needle being broken away to show more clearly the engagement of one of the teeth of the sprocket-wheel with the exible needle. Fig. 5 is a partial y top plan View of one of the flexible needles. i Fig. 6 is a detail side View of portions of the hooked needle and the forked needle, showing the hooked needle in position about to Q withdraw the weft from the forked needle.

Fig. 7 is a top plan view of the same, the end 5o of the forked needle being shown in section;

and Fig. 8 is a detail View showing the ends of the two needles in the positions which. they assume when the weft has been withdrawn from its engagement with the forked needle.

In the accompanying drawings, we have only shown so much of a loom as will enable a clear understanding of the construction and inode of operation of the flexible needles to which our present invention is directed.

The side frames of the loom are denoted by 6o A A', which frames are spaced apart in the usual manner. Brackets a ct project later ally from the side frames A A' at points a short distance above the lay-beam B, in which brackets are secured forwardly extended 65 stub-axles C O. Wheels D D', which are represented in the present instance as sprocketwheels, are mounted to oscillate upon the stub-axles C O'.

A pair of flexible weft-inserting needles E 7o E' have their inner ends secured at e e to the peripheries of the wheels D D. These liexi ble needles are arranged to be partially wrapped around the peripheries of the said sprockets when their free ends are drawn outwardly away from the shed of warp and to be unwound therefrom when their free ends are caused to engage each other atthe middle of the loom. In the present instance we have shown the needle E as the forked needle 8o and the needle E as the hooked needle. A single needle may also be used, arranged to pass entirely through the shed and` provided with a hooked or forked end.

As the bodies of the needles E E are quite similarfwe will proceed to describe the construction of one only of the said needles. The portion of the needle which is intended to be partially wrapped around the periphery of the oscillating wheel comprises a plurality 9o of in nerand outer links e2 e3, so arranged that the teeth of the wheel will enter the outer links e3 between the ends of 4the inner links e2 for positively moving the needle in either direction. The needleis made flexible in one The guides F roo F' are supported by brackets f f', projecting side frames A A and their upper ends secomm on.

'of the needles in connection with muchwider `tothe rotary cam-shaft j of the loom.

cured to flexible connections g g', which flexible connections engage peripheries of drums or pulleys g2 g3, mounted on the stub-axles CC and fixed to the wheels D D'. The wheels D D are rotated in the opposite direction, tending to withdrawthe flexible needles from the shed by meansot' flexible connections H Hleading from a central pulley or drum I Vto ldrums or pulleys-l1J h', mounted on .the

stub-axles C C' and fixed to rotate with the wheels D D'. These flexible connections I-I I-I also pass around idler-pulleys h2 h3, car` ried by the side frames A A.

The central-pulley I, from which the flexible connections H H lead, is fixed to rotate with a shaft t', mounted in suitable bearings i t'carried by cross-bars a2 a3 ot the loomframe, the oscillating movement of which shaft t' is under the control of a cam J, fixed This cam J-engages a stud or roller 7c on a rocking lever yK, hinged to the cross-bar d3, above referred to, the free end of the said lever having Icommonlyvused the loom is permitted to oc-` cupy much less lateral space than has been VIt furthermore permits of the use looms than it has been possible to do before,

slight movement of the controlling-cam will impart a'great movement of the needles.

Furthermore, by making the needles flexible vention.

in one direction from astraight line and inflexible in all other directions we are enabled to force the needles positively toward each other within the shed without any danger of the needles buckling. K

It is to be understood that by the use of the term flexible in connection with the weftinserting needles hereinbefore set forth we mean a needle which may be easily bent, so as to be capable ot' being wrapped around a drum at the side of the loom instead of causing it to project in a straight line'away from the side of the loom, as has hitherto been usual. The term flexible is used to distinguish our improved needle from the sti needles already in use, which needles may be possibly bent from their normal straight position, but which arenot easily bent or pliant.

It is evident that changes might be resorted to in the form, construction, and arrangement of the several parts withoutV departing from thespirit and scope of our in- I-Ience we do not wish to limit ourselves strictly to the structure herein set Vforth b u t What We claim isl. A weft-inserting needle for needle-looms, flexible in one direction from a straight line and inflexible in the opposite direction, substantially as set forth. t

2. Aweft-inserting needle for needle-looms being flexible in one direction only from a straight line and inflexible inail other directions, substantially as set forth.

3. A weft-inserting needle for needle-looms comprising a plurality of links so connected .that the needle will be flexible in one direction from a straight line and inflexiblein the yopposite direction, substantially as set forth.

Inv testimony that we claim the foregoing yasvour invention we have signed our names,

in presence of two witnesses, this 24th day of November, 1900.
