ABSTRACT:
A convertible sewing machine bed lid and hinge arrangement includes a lid that may be pivoted downwardly to expose an elongated arm for sewing tubular garments. The lid has depending pivot bosses and the bed has a web casting that includes legs connected to the bosses by the hinge pins fitted into apertures in the bosses and slots in the legs. A pair of leaf springs held by projections that interlock with the casting entrap the pins within the slots and urge them toward a closed extremity of the slots. Latching projections on the free side of the lid are resiliently forced into recesses in the arm to retain the lid in a horizontal position to provide an expansive work supporting surface.
