ABSTRACT:
An ice cube storage bin located beneath an automatic ice maker of a domestic refrigerator contains a pair of elongated ice dispensing rams that reciprocate along parallel lines, one of the rams moving toward the front of the bin, as the other moves toward the rear. The rams are interconnected by a pulley mounted belt that pulls one ram to the rear of the bin, as the other ram is pushed toward the front of the bin by a drive mechanism. The drive mechanism includes a pair of cam discs eccentrically mounted in opposed relation on a common motor shaft located outside of the bin adjacent its rear wall. A pair of resilient lever arms, having their top ends pivotally mounted to the outside of the rear wall of the bin and their bottom ends pivotally connected to the rearward ends of the rams which extend from the interior of the bin, are engaged at their intermediate portions by the rotating cam discs wherein the rams are alternately pushed by the bottom ends of the lever arms toward the front of the bin. The use of dual reciprocating rams, and the simplified push-pull drive means including the pulley mounted belt and the eccentric cam discs, provide a highly efficent and reliable ice dispensing mechanism.
