ABSTRACT:
Mechanism in a sewing machine for actuating the feed dog includes a pivoted actuating arm carrying on its distal end a feed dog support which is rockable about a vertical axis and also is slidable vertically. The feed dog support includes an arm which cooperates with an arcuate guideway which controls the attitude of the feed dog support so that the feed dog is maintained in proper work feeding attitude in its horizontal movement. Additional means effect vertical movement of the feed dog support in synchronism with the horizontal movement.
