SHUTTLE-OPERATING MECHANISM FOR LOOMS FOR WEAVlNG WIRE.

SPECIFICATION forming part of Letters Application filed January 9,1890. Serial No. 336,347.

To all whom it may concern.-

Be it known that 1, WILLIAM HARGREAVES, a citizen of England, residing at No. 19 Vernon Street, Broughton, Manchester, in the county of Lancaster, England, have invented a new and useful Shuttle-Operating Mechanism for Looms for Weaving Wire, (for which I have obtained a patent in Great Britain dated January 29, 1889, No. 1,599,) of which the following is a specification.

Wire fabric is usually woven by hand at considerable cost of time, labor, and money. My invention is designed to effect economy in this manufacture by the use of apparatus which, being adapted to a power-loom, enables the weaving of wire to be performed by power. I shall describe the apparatus for this purpose.

Referring to the accompanying drawings, Figure 1 is a side view, and Fig. 2 is an end view, of one of a pair of appliances for effecting the strokes of the weft-shuttle, one of these devices being applied at each side of the loom. Fig. Sis a longitudinal section, nd Fig. 4 is a transverse section, of the shuttle for holding the bobbin of weft-wire.

The shuttle (shown by Figs. 3 and 4) consists of a tube a, into the ends of which are screwed conoidal bosses a having central recessed holes 6'. On unscrewing either of these bosses the spool b, carrying the weftwire, can be introduced, the wire being passed through a lateral hole 0. Either end of the spool b is provided with a spring 01, which, by its friction on the interior of the tube a, gives the necessary drag to prevent the weftwire from unwinding too freely. At each side of the loom is arranged the apparatus shown in Figs. 1 and 2. The cam or counter shaft f, timed to the stroke of the loom by means of bevel-gears g, works a cross-shaft Patent No. 439,145, dated October 28,1890.

h, carrying a cam, which gives reciprocation to a lever k, pivoted at l. The upper end of the lever is has a slotengaging a pin projecting from a carriage g, which has flanged rollers r running along guide-rails p. A rod 7b, attached to the carriage q, extends through a guide 3, which has its mouth enlarged to receive the shuttle. On the shaft his fixed a cam-ended arm t, which in revolving meets a roller u, adjustable on the lever 70, and starts the lever on its back-stroke, which is completed by the strain of a spring 10. A'bufEer w receives the blow of the carriage q, and a bufier y receives the blow of the lever is when it makes its back-stroke.

Having thus described the nature of this invention and the best means I know for carrying the same into practical efiect, I claim- 1. In a loom, an appliance for moving the shuttle, consisting of a cam, the cam-shaft to which said cam is geared, a lever caused to reciprocate in one a spring for causing it other direction, and a rod moved to and fro by the lever to push the shuttle through the shed, substantially as set forth.

2. In a loom, a shuttle formed as a tube, containing the weft-bobbin, and provided with ends adapted to receive the end of the push-rod, substantially as described.

In testimony whereof I have signed my to reciprocate in the two subscribing witnesses, December, 1

this 19th day of WILLIAM HARGREAVES. Witnesses:
