Abstract
Abstract A sewing machine cabinet adapted for use with free arm type sewing machines having a sewing machine support platform including a recessed lower support surface. The cabinet includes a front rail pivotable 180 degrees between a flat bed position in which the top surface of the rail is coextensive with the top of the cabinet and a second position in which the bottom surface of the rail is coextensive with the lower work support surface. A pair of brackets are secured to opposite sides of the bottom surface of the rail and are journaled on studs supported on brackets on opposite sides of the cabinet. A spring biased plunger device is provided on at least one side for locking the rail in either the flat bed or cylinder bed position.
