Abstract
A chuck for suspending a specimen holder from a vertical drive shaft to permit the specimen holder to be rotated about the axis of the drive shaft and also pressed downwardly against an abrasive platen or the like which may also be rotated in the same or opposite direction, the chuck being biased to its locking position by a spring and being releasable through manual rotation of a sleeve member to overcome the spring force.
