Abstract
A dual action shaker table useful in permitting various modes of shaking the objects. The shaker table provides either a substantially reciprocating shaker motion or a true rotary shaker motion using two cooperating parallelogram linkage constructions in cooperation with a drive link and a driving mechanism. Switching between these two modes of operation is carried out by removably affixing a part of one link or a part of another link to the table.
