ABSTRACT:
A plurality of ice cube grappling members are equiangularly pivotally mounted via pivot pins at the bottom of a tubular member for movement to a closed position in which they come into close proximity with each other at an area beyond the tubular member and to an open position in which they spread apart from each other at the area to encompass and grapple an ice cube. A rod extends through the tubular member and is movable in axial directions therein. A disc is affixed to the rod at an end thereof outside the tubular member and the grappling members are coupled to the disc. A spring in the chamber urges the disc in a direction which maintains the grappling members in closed position. The rod is manually movable against the action of the spring to move the grappling members to open position.
