Abstract: 456,182. Looms. SMITH, H. G., and SHACKLETON, G. W., Northbrook Works, Keighley, Yorkshire. Feb. 1, 1935, No. 3256. [Class 142 (i)] Stop - motions, weft. -In a multiple-shuttle loom in which stoppage is not effected until the fourth pick after indication of weft exhaustion, the weft feeler is connected with a lever 4, arranged above the usual lever 5 operated by the weft fork. Upon weft exhaustion the lever 4 is withdrawn from beneath the projection '7a on a lever 7 which falls and also allows the rod 8 to fall. In a belt-driven loom which will run for two picks after the stop lever 12 is released, this lever is released on the second pick by an eccentric on the low shaft through a rod 10 and member 9, the eccentric being so set, that when the rod 8, Fig. 5, first falls a block 6 thereon falls on the member 9 which slides under the block 6 but does not stop the loom. When the member 9 moves back, the block 6 falls further and the member 9 at its next advance pushes the block 6 and releases the stop lever 12. In a loom driven electrically or through a clutch the mechanism shown in Fig. 8 is used, thus allowing for the whole of the four picks delay. In the first pick the block 6 drops on to a disc 15 slidable on the rod 10. On the second pick the disc 15 is pushed beyond the block 6 and this block drops on the member 9. At the third pick the member is withdrawn from beneath the block 6, and at the fourth pick the member 9 pushes the block laterally and releases the stop lever 12.
