An ice barrier for a selective ice cube and crushed ice dispenser having a crusher section including a crusher arm mounted to a horizontal shaft axially rotatable in either direction, and a stationary crusher arm mounted to one side of the shaft. When the shaft is driven in one direction, ice pieces fed to the crusher section are caught and crushed between the rotating and stationary crusher arms. However, when the shaft is driven in the opposite direction, ice pieces escape down the side of the shaft opposite the stationary crusher arm thereby avoiding being crushed. The ice barrier is frictionally coupled for rotation with the shaft between a first position in the whole ice piece path and a second position out of the path. Accordingly, the ice barrier blocks the whole ice piece path when the crusher is operated in the ice crushing mode.

A selective ice crusher that is fed whole ice pieces and optionally dispenses either crushed ice or whole ice pieces, said ice crusher comprising: a horizontal shaft; means for axially rotating said shaft in either direction; a first stationary ice crusher arm mounted on one side of said shaft; a second crusher arm mounted to said shaft for rotation with said shaft wherein, when said shaft and said second crusher arm are rotated in one direction, ice pieces fed to said ice crusher are caught and crushed between said first and second crusher arms, and when said shaft and second crusher arm are rotated in the opposite direction, ice pieces fed to said ice crusher fall down a path on the side of said shaft opposite said stationary crusher arm wherein said selective ice crusher dispenses whole ice pieces; and means rotatable with said shaft to a first position in said path when said shaft is rotated in said one direction for preventing whole ice pieces from falling down said path when ice pieces are being crushed, said preventing means being rotatable with said shaft to a second position out of said path when said shaft is rotated in said opposite direction so that ice pieces are free to fall down said path.
