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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
