Abstract: An ice shaving machine in which a blade for shaving ice is adjustably supported by a blade mounting and adjustment plate for adjustment of the depth of penetration of the blade into a slot and thus into the ice, and is also adjustable to level the blade across the slot. A unique drain system, is also provided, in which at least one air gap is provided between the ice receptacle and a drain tube to prevent migration of molds, bacteria and the like into the ice receptacle from the drain tube. A drive motor is connected through a drive shaft for direct driving engagement with an impeller, and serially arranged plural moisture seals are associated with the shaft to prevent movement of moisture along the shaft to the motor.
