  • Patent number: 4575012
    Abstract: An ice shaving apparatus (10) includes a housing (12) having a surface (20) for supporting an ice billet. A cutting head (59) is rotatably supported in one end of the housing and functions to discharge ice shaved from the billet through an aperture (50). The cutting head is rotatably supported in a drum (70) having a boss (90, 120) projecting rearwardly therefrom. The boss has a bearing receiving aperture (92, 122) formed therethrough. Sealed ball bearings (100, 130) are positioned in the aperture and rotatably support a shaft (48, 48') which in turn supports the cutting head. A slinger (110, 160) is mounted on the shaft between the cutting head and the bearings and serves to prevent water from engaging the bearings.
