ABSTRACT:
In a zig-zig sewing machine an automatic adjustment is provided for obtaining the correct values for stitch-length and upper thread tension in sewing fancy seams or button holes by moving a setting knob for such seams to the required symbol. The adjustment is made independently of the existing setting established for stitch-length and thread tension by the use of a pattern selector which in addition to selecting a required pattern activates controls for cloth feed and over-thread tension by a cam and linkage system which transmits movement from the pattern selector directly to an adjustable cullis and thread brake.
