  • Patent number: 6863520
    Abstract: The auger scoop is a handheld, cordless appliance for scooping frozen substances that has three components: an auger unit, a power unit, and a wall-mountable charger unit. The auger unit consists of a cylindrical tube having a flat, angled blade slightly recessed within the lower end and an angled butt plate at the upper end. The auger unit features a shaft extending from the upper end which is inserted into the power unit. The power unit consists of a rechargeable battery pack, a housing, and a motor and drive assembly that are activated by a switch on the external housing. When activated, the power unit rotates the tube, thereby rotating the blade and allowing the auger unit to bore into the frozen substance. The charger unit features a plug with which it is connected to a wall socket, an AC to DC converter, and a receptacle for the power unit.
