680,470. Coiling slivers. T.M.M. (RESEARCH), Ltd., WATSON, W. H., OSBALDESTON, J., and ROCHE, J. Feb. 14, 1951 [March 7, 1950], No. 5749/50. Class 120(iii) Relates to sliver-coiling apparatus of the type in which the coiling operation is effected at least in part by the rotation of delivery mechanism in the coiler head, and which comprises means for transferring the coiler head automatically, after a timed interval sufficient for the filling of one can, to another can placed ready to receive the sliver. According to the invention, means are provided for swivelling the coiler head from one can to another without necessitating interruption of sliver output, such means being in operative relationship with, and adapted to be operated at predetermined time intervals by, means for measuring the length of sliver delivered by the feeding mechanism. As shown, Fig. 3, the coiler head is carried at the top of a column 2, rotatable in a bracket 7, and is driven by a shaft 20 coupled by gearing to the calender rolls 10 (not shown) and 11 of a carding engine. A worm wheel 29 and a counter 54 are also driven from the calender rolls. After delivery of a predetermined length of sliver into a can 52, the counter closes a switch 54a to momentarily energize a solenoid 39 which moves a spring- loaded detent 35 to release a pawl 33. The latter, which is carried on a disc 32, springs into engagement with a ratchet wheel driven by worm wheel 29 so that disc 32 is carried around for one revolution until pawl 33 engages detent 35 again. Disc 32 is integral with a shaft 42, Fig. 5, one revolution of which produces rotation of a gear 45 through 180 degrees and, via a crank pin 47, connecting rod 48 and arm 50, a swivelling through about 90 degrees of a sleeve 5 connected to column 2 so that the coiler head is swung into position over an empty can 53. Rotation of an arm 43 on shaft 42 also moves a slide 60 to oscillate a lever 62 by which the counter is re-set to zero. In a modification, the counter is replaced by a huntercog mechanism constantly driven from the calender rolls; on the impingement of the abutment cogs of the mechanism a ratchet- and-pawl clutch is operated as before to swivel the coiler head. A separate plate 96 between the cans prevents entanglement of the sliver. Specifications 636,352 and 679,027 are referred to.
