Abstract
In a zigzag sewing machine a first group of pattern cams is rotated with a predetermined speed relative to a second pattern cam group by the arrangement of a transmission means between the first and second groups. A biasing means normally biases a cam follower to engage a selected pattern cam in said first and second groups. Cam selecting means operate to disengage the cam follower by way of the bias means and slidingly move the follower to a selected position along the cam groups.
