Abstract
In a sewing machine, a clamp-type work feeder includes an articulated, rotatable, telescoping tube carriage which can move in either direction parallel to the lower arm and rotate about the axis of the cylindrical end of the lower arm in accordance with a stored stitch program. A cylinder actuated clamp mechanism pivotally attached to the carriage allows simple work insertion and full peripheral stitching without unduly obstructing the operator's view or access to the stitching area.
