ABSTRACT:
A rotary index table wherein a detent oscillating about the table axis of rotation is translated radially inwardly during indexing and retracted radially outwardly during the return stroke of the detent, both actions being accomplished through a positive acting toggle link arrangement. The positive detent engagement with the table during indexing prevents table overtravel, and a locking detent is utilized to produce final table orientation. The table also includes expansible chamber motor means axially translating the table into a frictional locking engagement with its base.
