ABSTRACT:
A work supporting table has a carriage which extends beneath the bed of a press and a table top which extends over the bed. The carriage has wheels which rotate about eccentric spindles on the ends of the two axle shafts. Chains are wrapped around these shafts and forces are applied to the chains by an air cylinder mounted on the carriage. When the chains are drawn taut, the axles rotate such that the spindles move downwardly and cause the wheels to descend with respect to the carriage frame and thereby lift the table upwardly. The wheels when so disposed support the table with its table top slightly above the press bed. Conversely when the chains are released, the wheels move upwardly and the table top descends onto the press bed which supports it so that a force applied to a workpiece on the table top is resisted by the press bed.
