Title: Apparatus for feeding sliver successively to a series of machines
IPC: D01G23/00
Filed: 1919-12-18
Abstract: 157,634. Macintyre, L. G. Dec. 18, 1919. Feeding webs. - In feeding slivers to a succession of two or more machines, the sliver is delivered at a constant speed by rollers A', A<2>, Fig. 1, to a pair of rollers B<1>, B<2>, which are driven at a slightly greater surface speed than the sliver. When it is desired to divert the sliver from o n e machine to the next these rollers are reversed to break the sliver, then stopped, then restarted. During the reversal and stoppage, the sliver accumulates in a loop in a gap behind the rollers. The rollers are driven through a sliding clutch H, Fig. 3, comprising two toothed members H<2>, G<1> to give the normal drive and two coned friction members H', F' to give the reversed drive. The clutch is operated by a link J<2> actuated from the machine being fed, through a slide J having a slot J<3> with inclined ends J<4>. A lever J<6> engages the slot and the clutch. Movement of the pin J<5> on the lever J<6> up or down the inclined slots J<4> throws the clutch over from one side to the other. To limit the amount of the reversed motion a ratchet K on the shaft B<3> of the upper roller is engaged by pawls K<1> on a shrouded disc K<2> loose on the shaft. The disc is capable of motion between two adjustable stops K<4>, K<5>. In the direction of reversed motion the stop K<4> acts to lock the ratchet wheel and prevents further movement of the rollers B<1>, B<2>. Whilst the rollers are locked the friction members H<1>, F<1> of the clutch H slip one over the other.
