Abstract: A ball bearing actuation mechanism includes a circular gauge wheel rotatably mounted in an interior chamber of a housing below an inlet passage and adjacent to outlet and overflow discharge openings of the housing and a curved retainer wall mounted to the housing in the interior chamber adjacent to a peripheral groove on the gauge wheel so as to form a channel therebetween which extends between the inlet passage and discharge outlet opening of the housing. The peripheral groove has a length preset to receive a preset number of ball bearings in single file fashion therein when the ball bearings are deposited into interior chamber via the inlet passage such that any ball bearings above the preset number deposited into the inlet passage of the housing will divert to the overflow discharge outlet of the housing.
