Abstract

21,499. Hollingworth, E., [Crompton & Knowles Loom Works]. Sept. 21. Shuttles, changing bobbins and the like in, automatically; w e f t , cutting; shuttles. – In looms having plain and shifting shuttle boxes for two or more shuttles a n d a compartmental magazine for fresh ‘bobbins, weft – cutting devices in the shuttle are actuated by a tripfinger on the lay to sever the weft after laying a full pick when a reversely-wound length of bobbin commences to unwind, as described in Specification 5033/09, side weft – fork mechanism being thereby operated whereby a shaft 34, Fig. 2, and a shaft 30 actuated therefrom by slotted-lever mechanism, are rocked. A lever 20 fast to the shaft 30 carries a pin 19 supporting hooks 18 for operating the projections 16<1> of levers 16 connected by lever mechanism to the bobbin-head supports 9 and the bobbin-tip supports. Each shuttle has a side plate 4<1>, Fig. 4, provided with an opening 4<3> varying in position in each shuttle and in alinement with an opening in the body of the shuttle. Indicating-levers 73, Figs. 2 and 4, for each shuttle, engage with the plate when the lay beats up, and all except one (namely the one engaging with the opening) are forced back by the plate, so that projections 73<3> on the levers 73 engage and rock levers 77, thereby depressing the corresponding hooked levers 18 against the action of spring-actuated pins 79. A pawl 75 retains these levers 77 in their raised positions, but is released by the upward movement of a lever or levers 77. The hooked lever 18 corresponding to the indicating-lever that registers with the opening in the shuttle 4 in use remains in its raised position, and, when the shaft 30 is rocked, engages the corresponding lever 16 and causes the supports of the corresponding particular compartment of the magazine to release a bobbin therefrom. A side extension 58<1> of a spring blade 58 on the shaft 34 engages a projection 59<1> on a dagger 59 pivoted on the downwardly-extending part of the transferrer arm 61, thereby raising the dagger into the path of the lay bunter, the transferrer being thus operated to feed the bobbin into the shuttle. The slide 36, Fig. 11, of the side fork 38 is held in its outward position by a spring latch, a plate 36<2> on the slide acting upon a spring blade 44, which extends under and engages a hook-shaped arm 38<2> on the weft fork and raises it from the weftfork hammer 40. The blade 44 is secured to a rocking pin which has a limited motion. A pin 48 on the slide operates the upwardly-bent fork-shaped end of a rocking wire or rod 49 held by a strap at its inner end, and cranked at 49<2>, Figs. 2 and 6, to engage the slotted end of a vertical and vertically-moving slide 51, supported in a track or way in the downward extension 52<1> of a stopping-lever 52 pivoted at its outer end on the shipper stand or bracket 54. The slide 51 is thus raised out of the path of a lever 55 operated by the centre weft-fork stop-motion, which is thereby prevented from stopping the loom. A cam-operated verticallymoving. upright rod 65 carries a hub 66 with a pin 67 to engage the dagger 59 and move it downwards periodically in case it is in its raised position. The transferrer arm 61 carries a pin on which is loosely mounted the transferrer 69 for engaging the head or butt end of the bobbin, a pin 70 on an upwardlyextending arm 69<2> of the transferrer being guided in a slot 6<1> to cause the transferrer to move correctly. The tip-engaging arm is secured by a set-screw ’71 to the transferrer. The upper part of the magazine is inclined outwards so as to hold the heads and tips of the bobbins out of line with one another. The lower part of the magazine and the compartments therein are vertical, and converge towards the discharge opening. The bobbin supports have concaved recessed portions for supporting the lowest bobbins and convex portions for passing under the bobbins next to the lowest bobbins when the supports are, rocked. Both the butt and the tip supports are fast to rockshafts 11. A plate, of which the upper end extends over the shuttle-race and forms a mouthpiece for the shuttle, has an opening for the side weft fork, and carries an eccentric bolt, in which is loosely mounted the finger engaging the cam-shaped head of the bolt that moves the cutter knife to sever the weft carried into a recess in a plate forming part of the threading-mechanism of the shuttle. The bolt is turned to raise or lower the finger and is secured by a set-screw in a boss on the plate. Checking shuttles.-The shuttle binder has an offset for the entrance of the bent ends of the indicating-levers.
