9. An ice crushing mechanism comprising:
-
a housing, a first chamber formed in the housing and defined by a top wall with a first opening therein, a first bottom with a second opening having an angular extent of no more than 110 degrees therein angularly offset from the top wall opening and a circular outer wall, a second chamber formed below the first chamber in the housing and defined on the top by the first bottom wall of the first chamber, on the bottom by a lower, second bottom wall with a third opening having an angular extent of no more than 110 degrees therein angularly offset from the first bottom wall opening by approximately 180 degrees and a circular outer wall, a rotatable spindle positioned in the housing extending essentially vertically through a central portion of both the first and second chambers, at least one ice crushing blade rotatably carried on the spindle and positioned in the first chamber, and a wiper rotatably carried on the spindle and positioned in the second chamber, the wiper comprising a plurality of arms, each attached to be rotatably driven by the spindle and each with a free end terminating closely adjacent to the outer wall, and each having a height equal to a height of the second chamber, the arms being angularly spaced apart from each other such that at least two arms block all paths between the second opening and the third opening. - View Dependent Claims (10, 11)
