Title: Improvements in straight-bar knitting machines
IPC: D04B15/54
Filed: 1954-02-17
Abstract: 747,386. Knitting-machines. MONK (SUTTON-IN-ASHFIELD), Ltd., S. A., and MONK, S. A. Oct. 4, 1954 [Feb. 17, 1954], No. 4595/54. Class 74 (2). The chain drive H for the main yarn carrier bar of a straight-bar machine is derived from a rack R<SP>3</SP> through gear wheels R<SP>2</SP>, R, T and dog clutch U to sprocket wheels J on which the chains ride. A certain amount of clearance is provided between the dogs of the clutch to provide a lost-motion drive to the chains. A splicing yarn carrier bar is also driven from the gear wheel R through a similar train of wheels but this drive does not include a clutch. The drive for the main and splicing carrier bars is therefore such that the splicing carrier bar maintains a lead over the main carrier bar in each direction of traverse as the initial movement of the main carrier bar is delayed whilst the dogs of the clutch take up the lost motion.
