Abstract
In a zigzag sewing machine, a mechanism for producing stitched patterns includes a shaft carrying a first group of pattern cams and a second group of pattern cams rotatable by a drive shaft and having different speed reduction ratios. Two followers movable by a pattern selecting dial via a pattern selecting shaft are engageable with the cams of the first and second cam group, respectively. It is possible to select patterns by a control of an actuating pawl which is carried out by operating an independently provided selecting dial. The stitched patterns of the conventional reduction ratio may be controlled without changing their size.
