Abstract
Successively finished drills or other tools are ejected from a chuck into successive angularly spaced openings in a rotary turret, mounted on a carriage with a power device for reciprocating the turret into and out of an unloading position. A ratchet wheel on the turret is indexed through successive detented positions by engagement of the ratchet wheel with a pawl, as an incident to the reciprocating movement. The pawl is mounted on a stationary pivot and is biased into the path of the reciprocating ratchet wheel.
