Clutch for a textile machine

摘要

The pawl is retracted from the intermittently rotatable input shaft via a controlled abutment and a spring biased lever-mounted or piston-mounted roller. The abutment serves to start retraction of the pawl while the spring biased roller presses against a non-circular surface of the cam plate on which the pawl is mounted to complete removal of the pawl from the recess. The cam plate also has one or more cam surfaces for resetting the abutment after the pawl has been engaged in the shaft.
