  • Mounting adapter having locking taper removal arrangement
    Patent number: 4890947
    Abstract: A mounting adapter for a centrifuge includes an internal chamber having a lifting and a locking surface therein. The head of a connecting member is captured in the chamber and is rotatable by a tool insertable through an access bore in opposed angular directions. Rotating the connecting member in one direction brings it into abutting contact with the locking surface to hold tapered surface surfaces on the adapter and on the spindle in locked engagement. Rotation of the connecting member in the opposed direction causes the same to abut against the lifting surface to assist in separating the tapered surface from each other.
