Abstract

A pneumatically actuated needle bar mechanism for use in a two-needle sewing machine of the vertical hook lockstitch type is disclosed. The pneumatically actuated needle bar mechanism selectively controls the position of either or both needles and positively locks either or both needles in either the sewing (engaged) position or the non-sewing (disengaged) position. The mechanism is controlled by pedal operated remote pneumatic valves.
