1. An ice shaving apparatus comprising:

  • a stationary drum comprising a generally planar rear plate wall and an annular rim having a predetermined inside diameter and having a discharge aperture formed therein;

    a cutting head comprising a circular plate having an outside diameter substantially equal to the inside diameter of the rim of the drum and adapted for rotation therein;

    the circular plate of the cutting plate having a plurality of radially extending slots formed therethrough;

    a plurality of blades each mounted on the circular plate for shaving ice from a billet so that the shaved ice passes through one of the slots in the plate and into the drum;

    a plurality of vanes secured to the circular plate of the cutting head for rotation therewith for directing shaved ice received through the slots through the discharge aperture in the drum;

    the rear plate of the drum including a boss having an aperture extending therethrough which is coaxial with the rim of the drum and with the circular plate of the cutting head;

    the cutting head further including a shaft extending rearwardly from the circular plate through the aperture of the boss of the rear plate of the drum;

    a plurality of spaced apart, sealed, antifriction bearing means mounted in the aperture of the boss of the drum and receiving the shaft of the cutting head therethrough and thereby rotatably supporting the cutting head; and

    slinger means comprising a relatively large diameter portion mounted on the shaft for rotation therewith and positioned within the drum between the cutting head and the antifriction bearing means for centrifugally discharging water from the shaft and thereby preventing water resulting from operation of the cutting head from engaging the antifriction bearing means.
