Abstract: A table for supporting an object such as a free-arm sewing machine and for allowing the object supported thereby to be adjusted heightwise relative to the work surface of the table. The table includes a platform member for bearing the object. The platform member is adjustable heightwise relative to the work surface of the table between a first position substantially even with the work surface of the table and infinite positions below the work surface of the table. At least one of the infinite positions of the platform member is positively defined by a stop member to allow the platform member to be readily moved between the first position and the position defined by the stop member.

Abstract: A sewing cabinet which includes provisions for electrically carrying a typical sewing machine head between a concealed/stowed position and at least one working position. The structure includes a carriage assembly having a platform which restingly supports the head. Peculiar structure is included for stabilizing the platform in various positions and for driving the carriage assembly therebetween. In one embodiment the carriage assembly is stabilized by a plurality of fixed upright rods which are slidably engaged by sleeve structure affixed to the carriage assembly. In this embodiment the carriage assembly is driven by a single upright externally threaded shaft protruding directly upward from a motor with internally threaded structure being affixed to the carriage assembly and threadedly engaging the shaft to selectively drive the carriage assembly up or down. In another embodiment the carriage assembly is stabilized by a plurality of externally threaded power driven mandrels.
