Abstract

A mechanism is disclosed in which the main driving mechanism of a sewing machine is harnessed simultaneously to actuate a thread wiper and a tension release mechanism for the sewing machine. Operation of the mechanism may be initiated by a solenoid which may be advantageously small in size and power since the solenoid does not supply any of the driving force incident to the operation of the thread wiper or tension release mechanisms.
