Abstract
A convertible sewing machine bed which includes a base having a longitudinally extending cylinder bed and a spring biased work supporting panel that is movable in one direction with respect to the arm and simultaneously shiftable in another direction with respect to the cylinder bed. The shifting movement is effected by the camming action of a single latch detent being moved into and out of a latch seat. The single latch detent and the latch seat, when in engaging relation, also serve to hold the support member in a work supporting position contiguous to the cylinder bed.
