Abstract
A pivoting linkage mechanism provides a linear translational path for a tool holder over a predetermined displacement distance. A single linear motor drives the tool carrying end of the mechanism within a displacement plane defined by collective rotation of two sets of parallel, four-bar linkages joined by a transfer plate. A control link between a frame secured axis and an axis mid-span of a swinging linkage set further restricts pivotal displacement of the entire assembly. The translating tool holder supports a journal socket for the pivot axis of a third four-bar, parallel linkage for controllably swinging a secured article in a horizontal plane between opposite sides of the transfer apparatus.
