ABSTRACT:
A machine tool including a base having a work zone including a drive gear, a work shuttle having a pair of work stations each having at least one work spindle and an idler gear, the work shuttle assembly is mounted on the base and is displaced to alternately locate each of the work stations at the work zone and at a load/unload zone, and each of the work spindles is presented at a predetermined orientation at the work and load/unload zones by means of a gear rack mounted on the base for engaging each of the idler gears as the shuttle is displaced from one to another of the positions, the gear rack having at least a portion of the teeth thereof removed proximate the drive gear whereby the idler gear of the station located at the work zone will be operatively associated with the drive gear but will not be operatively associated with the gear rack, rotation of the drive gear is prevented as the work shuttle assembly is displaced and rotation of the drive gear is allowed when the work shuttle assembly is located at either of the two positions, and the work shuttle assembly is located at either position.
