The method of repetitively making discrete blocks of ice which is performed with apparatus having a plurality of adjacently disposed ice freezing pockets formed with a refrigeration evaporator as the base of each pocket of the pockets, horizontally extending and vertically spaced apart evaporator fins as the sides of the pockets, and horizontally pivotal vertical plates as the ends of the pockets. A refrigeration apparatus is provided to alternately freeze the refrigeration evaporator of the ice freezing pockets and very quickly and very briefly heat the refrigeration evaporator directly to loosen the ice blocks from the freezing pockets. Apparatus is provided to apply a force to the vertical plates until the immediate surfaces of the ice blocks are melted and loosened from the freezing pockets. The vertical plates thereon move the ice blocks within the freezing pockets, then are rapidly returned to an initial position which ejects the ice blocks completely from the freezing pockets.

An article of manufacture suitable for making ice blocks including a vertically disposed plurality of ice freezing pockets with each pocket of said freezing pockets comprising in combination: (a) a directly refrigeratable freezing member forming the base of each pocket; (b) at least two vertically disposed apart and horizontally extending fins attached with each freezing member and forming the sides of said pocket; (c) at least two horizontally pivotable and vertically disposed plates mounted contiguously with said freezing member and said extending fins to form the ends of each said pocket of said plurality of pockets; (d) said freezing member being of cylindrical shape with said fins extending around said freezing member and with said vertically disposed plates being pivotally mounted in spaced apart relation around said freezer for pivoted horizontal movement; and (e) each of said vertically disposed plates being pivoted on centers located away from its inner edge.
