Abstract
An ice maker comprising an elongated freezing tray (100) having arcuately shaped cross sectional configuration with equal-spaced separators (120) formed therein each in a plane normal to the axis of the elongated freezing tray (100) and comprising a rotatable assembly comprising a first hollow, cylindrical shaft (100) rotatably secured near both ends of the tray (100) substantially coincident with the axis of the tray (100) and having generally flat paddle-shaped ejector elements (114 and 115) formed thereon a second hollow, cylindrical non-rotatable shaft (160) positioned within the first cylindrical shaft (106) and non-rotatably secured at one end to the tray (100) assembly; a heating element (113) positioned within the second, hollow cylindrical shaft (160) comprising a power source (309) for supplying power thereto to heat the heating element (113) and by conduction to heat the first and second hollow, cylindrical shaft 160 and the ejector elements (114 and 115) to release the full crescent shaped ice pieces from the ejector element.
