ABSTRACT:
Improvements are disclosed for ice shaving apparatus of the type including (a) an ice receiving chamber having a cylindrical, upstanding sidewall and a substantially flat floor, (b) an elongate opening in the floor, (c) an elongate blade having a knife edge projecting through the opening into the chamber, (d) a removable cover for the chamber and (e) means for moving ice placed in the chamber against the knife edge to cut shavings from the ice. The improvements comprise an elongate, blunt, blade guard which is positioned adjacent to the blade and is movably mounted for movement from a recessed position in which a leading edge of the blade guard is recessed beneath the knife edge of the blade to an extending position in which the leading edge projects at least to the knife edge of the blade to provide a guard for the knife edge. Additional improvements include an ice press which does not have spikes or sharp projections extending therefrom and an outer chamber surrounding a rotating inner ice chamber, with the outer chamber having at least one window therein and with the inner chamber having designs placed thereon which are visible through the window in the outer chamber.
