Abstract
Abstract A cabinet and work table for a sewing machine having a convertible work supporting bed capable of conversion from a flat work supporting bed to a cylinder bed. The cabinet work supporting surface is divided into two parts, a fixed rear work supporting surface and a laterally shiftable front work supporting surface. The sewing machine is supported in the cabinet with the flat work supporting bed forwardly of, co-planar and contiguous with the fixed work supporting surface. The shiftable work supporting surface of the cabinet is laterally shiftable from a position co-planar with the fixed work supporting surface of the cabinet and the flat work supporting bed of the sewing machine to a position subjacent the flat work supporting bed of the sewing machine and the fixed work supporting surface of the cabinet whereupon the flat bed may be converted to cylinder bed use. An unexpected benefit has been noted with the cabinet work supporting surfaces at two levels and the sewing machine in either flat bed or cylinder bed mode in that the sewing machine can be used with greater comfort and effectiveness.
