Abstract
3573. Hollingworth, E., [Crompton & Knowles Loom Works]. Feb. 13. Weft-replenishing mechanism.-A weft-feeler locking device used in connexion with a twopart weft-feeler, such as is described in Specification 3271/10, comprises an additional slide or third member 27, Figs. 2 and 5, guided on the feeler-bed 5 and having a side extension 27' underneath the slide 8. The slide 27 is moved forwards by a spring 28, and is forced back by the weft on the full bobbin when the lay beats up, whereupon a projection 27<3> on the extension 27<1> acts on a set-screw 30 and causes the lever 21 to be rocked to the left to withdraw the feeler members 8, 19 out of contact with the weft on the bobbin. A spring-actuated locking-lever 33 then engages behind a rod 32 connected to the lever 21 and thus holds the lever 21 in this inoperative position, so that, on subsequent forward movements of the lay, and until a certain stage of weft-exhaustion has been reached, the feeler members do not engage with the weft on the bobbin. During this period, when a shuttle is present in the box at the feeler side of the loom, the slide 27 is moved sufficiently at the beat-up to cause a projection 27<a> on the slide 27 to engage the lower edge 39<2> of a spring - controlled bunter 39 on the lay, the hunter being thereby raised and being prevented from engaging the lever 33 and unlocking the rod 32. When the shuttle is in the box at the opposite side of the loom, so that the swell 14 is forced inwards by the usual lever 15, a wedge 15<a> on the lever 15 acts upon a stud 4) on the bunter 39 and raises it into inoperative position. When a certain stage of weftexhaustion is reached, the slide is not moved sufficiently at the beat-up to cause the projection 27<a> to engage the bunter 39, which therefore engages and rocks the lever 33, thus unlocking the rod 32, so that the feeler members are moved into engagement with the bobbin and thereafter act in the usual manner. The locking-device may be applied to an electric weft-feeler.
