346,602. Cutting and manipulating weft ends in automatic looms. BRITISH NORTHROP LOOM CO., Ltd., Daisyfield, Blackburn.-(Northrop Loom Co. ; Hopedale, Worcester, Massachusetts, U.S.A.) May 26,1930, No. 16125. [Class 142 (iii).] Upon call for bobbin change, an arm 9 moves a weft parter carrier 8 to the left whereby the movable blade 5 is moved away from the fixed blade 4 by the engagement of a projection 7 with a trip 12. At the same time, a bunter 32 on the carrier pushes a spring-controlled plunger 27 mounted on the shuttle-box. A rack on the plunger rotates a wheel 26 geared to a wheel on a shaft 20 carrying a hook 19 adapted to engage the weft a extending between the bobbin and the selvedge and to position it for engagement by the weft parter 4, 5. When the transferrer is operated, a member 13 carried thereby engages the projection 7 to close the weft parter to sever and/or clamp the weft. When the carrier 8 returns to its normal position shown, the hook 19 returns to the position shown, clear of the shuttle. In order to prevent the secured ends of the wefts for transfer to the shuttle from being caught in the shuttle box and carried into the shed, an arm 37 having a hook end portion 38 is provided on the front plate of the shuttle-box to catch the new weft ends as the lay moves back.
