ABSTRACT:
The apparatus for making ice blocks comprises a hollow body containing projecting parts faced downwards. Referigerating fluid and heating fluid are circulated separately through this body. A tray is around the projecting parts in its uppermost position. This tray is supported by a mechanism between an uppermost and a lowermost position and a water supply line comprising a cock opens into said tray. When ice has formed on the projecting parts, an electric circuit is closed and the cock opens for some time. Thus the tray falls. In the lowermost position water flows away out of the tray and therefore the tray rises up to its uppermost position.
