ABSTRACT OF THE DISCLOSURE: A mechanism for a sewing machine for enabling the manual or automatic control of the direction and of the ampli- tude of movement of a transporting claw guide for material to be sewn. The mechanism is driven from the main driving shaft of the sewing machine via a cam and a series of intermediate lever members connected to a rotatable shaft connected to the transporting claw guide. The control is automatically accom- plished by means of a cam driven from the main driving shaft of the machine via the arrangement of levers to obtain back- and-forth movement of the claw guide or, when a cam follower is disengaged from the cam, the adjustments can be accomplished manually without the automatic back-and-forth movement.
