Abstract
A half crescent shaped ice piece maker comprising a freezing tray (100) having an inner surface arcuately shaped about a longitudinal radial axis and divided into crescent shaped water fillable cavities (112) in which the ice pieces are formed, and an ejector assembly (102) for rotatively moving the ice pieces out of the cavities (122) comprising a rotatable shaft (106) supported in bearings with its axis coincident with the radial axis, and with ejector assembly (102) further comprising a row of primary flexible, spring-like ejector elements (114) lying in a common plane and each secured at a first end to the shaft (106) and having its second end extend into one of the crescent shaped cavities (122) to divide the cavity (122) into rotatively leading and lagging partial crescent shaped cavities while water is injected and frozen therein and before the ejector assembly (102) is rotated to form leading and lagging rows of partial crescent ice pieces with ice bridges (152) around the edges of the ejector elements (114) between the leading and lagging partial crescent ice pieces (130) and (132) of each full crescent shaped ice piece, and a prime mover for rotating the ejector assembly.…
