Abstract: An auxiliary bed extension U-shape plate destined to be edgewisely mounted to the cylinder bed of a sewing machine for increasing the planar work supporting surface thereof. The bed extension comprises a main, rigid, panel defining an inner recess for shapingly conforming to the cylinder bed, the inner recess of generally quadrangular shape. The web of the U-shape extension plate is telescopingly extensible and the two side legs thereof are extensible with add-on strips, wherein the extensible bed is adjustable in length as well as in width. The panel is supported edgewisely to the cylinder bed in generally coplanar fashion to the work supporting surface of the latter, whereby an enlarged, planar, generally coextensive, work supporting surface is obtained by the cylinder bed and extension bed plate.

Abstract: A mounting arrangement for a sewing machine is disclosed, comprising a cabinet having an aperture in its top plate, a base plate on which a sewing machine is rigidly secured and an elongated narrow plank member pivoted to the base plate and to an edge of the top plate aperture. The plank member links the base plate to the cabinet. Supports and a locking device retains the assembly of the base plate and plank member in three positions: a top position in which the base plate and plank member are coplanar and level with the top plate to maintain the sewing machine in a free arm position; an intermediate position in which the plank member extends downwardly and vertically from the top plate and the base plate is horizontal to maintain the sewing machine in a flat bed position, and a lower position in which both the plank member and the base plate extend downwardly to maintain the sewing machine in stored tilted position within the cabinet.
