Abstract: A platform for mounting a sewing machine in a cabinet is disclosed which is pivotally mounted to the cabinet thereby allowing the sewing machine to be stored within the cabinet without being removed from the platform. This platform is intended for cylinder bed or convertible bed sewing machines in that it is also capable of raising and lowering the sewing machine, between a position where the work supporting surface of the sewing machine is coplanar with the cabinet top and a position where the work supporting surface is spaced above the cabinet top, without an accompanying horizontal shifting component. This enables the cabinet to be formed with a smaller sewing machine opening minimizing any gaps between the cabinet and the sewing machine and eliminating additional inserts needed to close these gaps.
