ABSTRACT:
The upper one of two spherical bearings supporting the needle bar of a sewing machine for endwise reciprocation is carried in a gate that is pivotally mounted between bifurcated portions of a fixed support located on the rear side of the machine casing. A link is pivotally mounted between bifurcated portions of the gate and operably connected to driving means effective to impart reciprocating movements to the gate resulting in zig-zag motion of a needle attached to the lower end of the needle bar.
