ABSTRACT:
Objects of various sizes are centered and releasably held with a holder member having an annulus and radially mobile object supports or flexible fingers projecting inwardly from that annulus for centering and releasably holding any of the objects inside that annulus. These radially mobile object supports or flexible fingers are of one piece with the annulus. Adjustable actuator members, which may project from an annular structure concentric with, and rotatable to, the annulus, engage the radially mobile object supports or flexible fingers for selectively moving the same radially relative to the annulus for an accommodation of any of the objects. Detents may be provided between the annular structure and the annulus for releasably retaining the annular structure in any of several annular positions relative to the annulus.
