ABSTRACT:
Disclosed herein is a tool for retaining and releasing ringed members. Although primarily intended for use in dispensing ringed members onto Bingo-type game cards, the tool may also be used to release any type of ringed member such as nuts or washers onto screws or bolts. Regardless of its intended use, the tool comprises an axially elongated, hollow tube having oppositely disposed ends, the outer diameter of the tube being less than the inner diameter of a ringed member adapted to be retained thereon and released therefrom. A radially expandable member is secured to one end of the hollow tube and is adapted to reciprocate between a radially retracted position in which individual ringed members may be selectively released from said tube and a radially expanded position in which ringed members are retained on said tube. A recapturing element is secured to the opposite distal end of said tube for collecting ringed members which have been deposited on an adjacent surface. When used in a Bingo environment, the tool is adapted to release ringed members onto a Bingo card, to collect ringed members from the surface of the Bingo card, and to store ringed members about the outer diameter of the shaft of the hollow tube.
