Low torque direct dialing pattern selection mechanism |
摘要 |
A low torque direct dialing pattern selection mechanism for a sewing machine having an operator actuatable control dial. Initial rotation of the dial effects an isolation of the cam follower mechanism from the cam influenced stitch forming instrumentalities. Continued rotation of the control dial causes selective positioning of a pattern cam follower for operational engagement with a desired pattern cam.
