Abstract

The present invention is an ice shaving apparatus comprising an oval shaped base with an oval shaped ice block shaving table mounted directly above the base by way of four tubular legs, an oval shaped upper plate mounted directly above the ice block shaving table by way of four additional tubular legs collinear with the lower four legs, threaded rods extending through the tubular legs, a motor, a gearbox, and a rack and pinion mechanism are mounted on the upper plate coupled to a vertically movable shaft and ice pick disk extending downward towards the ice block shaving table to engage and rotate the block of ice on the shaving table. The motor, electrical circuitry, the gearbox, and the rack and pinion mechanism are all located above the upper plate and are enclosed by a single housing. The ice block shaving table has a radially oriented elongate slot with a stationary angular shaving blade extending out of the slot. Rotation of the block of ice on the support table causes the shaving blade to cut shavings from the block of ice. The shavings then fall downwardly through the slot toward the base. Optimal visibility, use of space, structural integrity, stability and access is afforded by the configuration.
