ABSTRACT:
A mechanism, suitable for mounting in a sewing machine cabinet, is provided for supporting a sewing machine in a first position in which the work supporting surface of the sewing machine is coplanar with the cabinet top and a second position in which the bed of the sewing machine is elevated above the cabinet top allowing for free arm sewing. The mechanism includes a mounting cradle spaced in parallel relation above a base, which is pivotally mounted to the cabinet, and crossing brackets interconnecting the cradle and the base. A lever actuated linkage raises and lowers the cradle between the two sewing machine positions.
