LOOM FOR WEAVING WIRE.

Application filed March 26, 1924, Serial No. 702,125, and in Germany March 31, 1923.

This invention relates to looms for weaving wire and has for its object to provide an apparatus enabling hard wire to be woven without kinking or breaking up.

The known device of picking up. and seizing theweft wire in proximity of the selvedge of the fabric is combined with a device whereby the free portion of the weft wirelaterally of the fabric is held stretched.

The accompanying drawing shows an apparatus embodying the invention.

Fig. 1. being an elevation and Fig. 2 a plan view of the same.

Arranged laterally of the fabric 1, is a clamping device 2 (shown in section in Fig. 1) which consists of two resiliently mounted rails and guide wiresB for guiding the-weft wire into the clamp. A finger 5, adapted to swing transversely in relation to the fabric is mounted on the lay 4.

hen the shuttle 6 has completed its throw the lay 4: assumes in relation to the fabric the position shown in Fig. 2. The weft wire is then taut. V

In order to prevent slackeningof the weft wire after it has been beaten up by the lay 4, said wire is seized by the clamp 2, between whose jaws it is thrust by the beating up action. slackening of that part of the wire which extends from the shuttle to the clamp is prevented by the finger 5. This finger 5 is maintained in its inoperative position (Fig. 1) by the lever 12,which, when the pickershaft 8 is in its inoperative position rests against the stud 9 on the said shaft. When the picker shaft is actuated the stud 9 releases the lever 12 which is moved by the spring 10 so that the vfinger 5 is enabled, under the action of gravity and the spring 11 attached to it, to swing down and engage the weft wire 7 below it.

The weft wire 7 is kept taut by the finger 5 until the moving shuttle again exercises its pull thereon. The finger 5 is so shaped that the weft wire may readily slip off when the shuttle moves.

The finger 5 may be replaced by other means capable of maintaining the weft wire taut.

If the fabric to be made is of considerably less width than the loom, the hereinbefore described device is not sufficient. In order to provide continued support for the weft wire after it has slipped off the finger 5, a fork 13 is arranged on the lay 4. This fork is mounted on a pivot 19 arranged on a slide 14. which is adapted to slide on two thick wires orrods 15 and 16 on the lay. Aspring 18 attached to an arm 17 of the slide 14 maintains the fork 13 in the position'illustrated in full lines in Fig. 1. Coiled on the guide wire or rod 16 there is a spring 20 which automatically restores the slide L1 to the position shown in full lines in i'g. .1,

which position said slideoccupies, when the shuttle has passed through the shed and has run into the shuttle box. The tension of the spring 20 is adjustable by means of a sliding collar fitted on the guide wire or rod 16.

The guide wires 15 and 16 are secured to a head stock 21 provided with a guide rod 22 forming with its bearing 23 and nuts 24 means for stretching the wires 15 and 16. The

wires or rods 15 and 16 are rigidly attached to the lay at the opposite side and are supported in the centre of the loom, so as to prevent the said wires from sagging.

The guide Wire 15 carries an adjustable liftedover the said fork by the pull of the shuttle. When the shuttle starts on its travel the finger 5 descends and maintains the weft wire taut.

WVhen in the course of the continued travel of the shuttle, the weft wire is released by the finger 5, it is caughtby the fork 13'. The

- spring 18 is of greater strength than the spring 20 which acts on the slide 14, so that the fork 13 for the time being remains in its normal position and may be carried along together with the slide 14 by the weft wire, thereby putting the spring 20 under tension.

When the downwardly directed arm of the fork 13 meets the stop 27 the fork is caused to swing around into the position shown in broken lines. Immediately following this the slide is arrested by the abutment 25. During the continued travel of the shuttle the weft wire is drawn upwardly out of the fork 13 and the slide 14 is brought back by the spring 20 to its normal position which is determined by the stop 28. Simultaneously the spring 18 restores the fork 13 to its normal inoperative position.

In order to allow of making a. narrow fabric, several tensioning fingers may be distributed over the width of the loom instead of employing the adjustable straining device 13 above described.

Vhat I claim as my invention and desire to secure by Letters Patent of the United States is 1. In a wire weaving loom the combination with a shuttle a lay and pick mech anism, of a clamping device for engaging the Weft wire near theedge of the fabric, and means for engaging and holding taut the clamped weft wire between the shuttle and clamping device at the beginning of the pick motion.

2. In a wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric. and means on the lay for engaging and holding taut the clamped weft wire at the beginning of the pick motion.

3. In a wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric, and a finger on the lay for engaging and hold ing taut the clamped weft wire at the beginning of the pick motion.

61. In a wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric, and a. finger on the lay for engaging and hold ing taut the clamped weft wire at the beginning of the pick motion said finger being movable transversely of the fabric and descending on to the weft wire when the shuttle has begun to move, and said finger being shaped so that weft wire slides off it when ,the shuttle moves through the shed.

5. In a wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric, and a finger on the lay for engaging and holding taut the clamped weft wire at the beginning of the pick motion said finger being controlled by the pick mechanism.

6. In a wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric, and a finger on the lay for engaging and holding taut the clamped weft wire at the beginning of the pick motion, a spring for moving said finger into engagement with the weft, and a. device controlled by the pick mechanism for holding said finger out of engagement with the weft.

7. In a wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric, and means for engaging and holding taut the clamped weft wire at the beginning of. the pick motion, a second tautening device movable in the direction of the shuttle motion and adapted to be engaged by the weft when the latter is released by the first mentioned tautening device, and an adjustable stop for disengaging the second tautening device.

8. Ina wire weaving loom the combination with a shuttle a lay and pick mechanism, of a clamping device for engaging the weft wire near the edge of the fabric, and means for engaging and holding taut the clamped weft wire at the beginning of the pick motion together with a. tautening device movable in the direction of the shuttle motion and adapted to be engaged by the weft when the latter is released by the first mentioned tautening device, and an adjustable stop for disengaging the second tautening device, the latter comprising a slide movable on the lay, adapted to engage the weft moved by the shuttle, a fork pivoted to said slide, and an arm on said fork arranged to strike the lay.

9. The combination claimed in claim 8, together with a spring acting on the slide, an adjustable abutment limiting the movement of the slide through the shed, and a spring between the slide and the fork, for deflecting the latter, said spring being more powerful than the spring acting on the slide.

In witness whereof I have signed this specification.

EMIL JAGER.
