Improvements in or connected with Weft Stop Motions for Weft Replenishing Looms.

摘要

1523. British Northrop Loom Co., and Chadwick, H. Jan. 19. Stop-motions, warp and weft. - In a loom provided with automatic weft - replenishing mechanism controlled by feeler mechanism, weftfork mechanism for stopping the loom is used at the magazine side thereof, and comprises a weft fork 1 pivoted on a rod 2 fast to a spindle 3, which carries an arm 6 provided with a pin 7 engaging a slotted link 9 pivoted to the shuttle feeler 10. When, therefore, the weft-replenishing mechanism is operated and the shuttle feeler is rocked into operative position, the weft fork is raised into inoperative position, so as to allow the weft end from the exhausted bobbin to be moved into engagement with the usual cutting and holding mechanism 11, 12 and threadcatcher 13, the weft fork subsequently descending to operative position to the right of 'the weft end, which therefore does not later interfere with the weft fork. When the weft fails, a hook 14 on the weft fork engages a hammer 15 connected by lever mechanism 17, 18 to the shaft 19 carrying the ordinary vibrator 20 of the warp stop-motion, the movement of which is thereby arrested so that the loom is stopped. The movement of the weft fork from operative to inoperative position may be controlled from the replenishing - mechanism otherwise than through the shuttle feeler.
