An ice cube making machine having a vertical, open-faced freezing mold over which water is circulated from an underlying trough to build up ice. When the mold is full, the pump circulating the water is stopped and the ice is harvested. Harvesting is facilitated by a plunger that is biased to push ice from the mold. Water pressure from the pump holds the plunger against its bias until the pressure is released for the harvest cycle. The mold open face is covered by a water curtain having a lower lip underlying the mold open face so that the underlying trough need not extend substantially out from the mold, thereby permitting similar such units to be vertically stacked.

An ice making machine comprising, in combination, a substantially vertical mold having an open outer face divided into cube cells and being intimately associated with refrigeration evaporator coils, an open top drain trough underlying said mold, means for pressurizing water in said trough and lifting the water to the top of said mold so that water will flow over said open face and into said cells, a plunger mounted for movement into said mold for pushing formed ice out of said open face, means for biasing said plunger in said ice pushing direction, and means for applying said pressurized water to overcome said bias and hold said plunger out of said mold, whereby deactivating said water pressurizing means will cause the plunger to urge ice from the mold.
