Feed system for a sewing machine

An arrangement for adapting a flat bed sewing machine to support a convertible bed sewing machine for flat bed sewing includes a support bracket assembly and a support arm assembly which both extend into the cavity of the sewing machine. The sewing machine is fixedly mounted on the support bracket assembly for supporting the rear of the sewing machine. The support arm assembly supports the front end of the sewing machine and swings out of the way when not supporting the sewing machine to provide clearance for the sewing machine when the sewing machine is in its stored position within the cavity of the cabinet.
