  • Patent number: RE28835
    Abstract: A work cabinet, for mounting a sewing machine in different work positions and for housing the machine when not being worked, provides a drop shelf interiorly of the cabinet below the top working surface thereof for lowering the machine into the interior of the cabinet. The drop shelf carries a mount for the machine, by means of linkage which permits raising and lowering of the machine to different work positions. Pivotally fulcrumed on the drop shelf is a lever having a work arm and a power-input arm, the former underlying the machine mount so as to raise and lower the sewing machine when power, usually manual, is applied to the latter. The cabinet is well adapted to open-arm types of sewing machines, and is provided with a removable insert for its apertured top wall as an extender for the limited work surface of such top wall in the work positions of the machine.
