ABSTRACT:
A retractable spindle for connecting a drive to a driven instrumentality, such as a roll. The spindle includes an axially movable shaft which has self-contained hydraulic means for moving it axially to disconnect it from the driven instrumentality or connect it thereto. This arrangement avoids the need for external mechanical linkages used heretofore for retracting a spindle.
