ABSTRACT:
A needle bar reciprocation interrupting device is disclosed in which the interruption is effected by a solenoid at any lateral position of a needle in an arrangement wherein an upper end of the needle bar is swung in an arc with an intermediate portion of the needle bar supported in a ball and socket joint structure to result in lateral positioning of the needle. An unlatching frame is carried by bearings within which the needle bar undergoes endwise reciprocation thereby to move laterally with the needle bar. A solenoid supported on a bracket affixed to the sewing machine frame has its armature connected with a fork extension of the unlatching frame closely adjacent the ball and socket joint structure. When the solenoid is activated the unlatching frame is pivoted to swing a ramp portion thereof into engagement with a needle bar carried latch at the end of upward needle bar travel thereby to separate the needle bar from its endwise reciprocating drive mechanism when its velocity is close to zero.
