Abstract: A stationary tray melt-out ice maker for forming individual ice sections in a refrigerator. The tray has a plurality of crescent-shaped ice molding cavities and one arm of a rotatable harvesting comb is immersed in each ice molding cavity for freezing of ice with the arm embedded therein. Upon heating of the tray, the harvest comb is rotated such that the ice embedded arm sweeps the individual crescent-shaped ice from the molding cavities. Continued rotation of the comb causes the ice to contact stationary strippers which cause fracturing and stripping of the crescent-shaped ice from the arm and harvesting of two quarter round sections of ice from each crescent-shaped ice formation.

Abstract: A control system for a tray type refrigerator ice maker having a motor driven programmer for controlling ice harvest by means of tray rotation and twist for ejecting cubes to a collector bin. The programmer also drives an arm for bin level sweep, which, if interrupted by the presence of accumulated bin ice, opens a cutout switch in series with the motor. A temperature sensing curie effect magnetic switch is series connected with the bin switch and motor for delaying harvest cycle motor drive until the surrounding tray temperature is sufficiently below freezing to indicate ice presence in the tray. A heater is series connected with the motor and disposed to cause opening of the temperature sensing switch shortly after motor start. A programmer actuated by-pass switch in parallel with the temperature sensing switch is held close to continue motor drive through the remainder of the harvest cycle.

Abstract: A dispenser for storing and dispensing ice cubes in a dispensed condition substantially free of ice chips. An electric motor driven gear train is mounted in the bottom of the ice dispenser storage bin and terminates in an output pinion which engages with a shaft mounted rotor member. The rotor member rotates about a vertical axis and includes an upper spider like section having a plurality of circumferentially spaced radially extending arms which function to maintain the stored ice cubes in a loose condition. The rotor includes a flanged rotor section adjacent the bottom of the storage bin having a plurality of radially extending rib members on its top surface. A dispensing chute is tangentially aligned with respect to the rib portion of the lower rotor section and also the hub surface of the rotor and functions to channel the loosened ice cubes therethrough.
