| 175018000 | ICE BORING | 6 |
| 20090120688 | Method of attachment of a towing anchor to an iceberg - A drilling bit for penetrating an iceberg a predetermined distance to establish an anchor point for towing the iceberg to a predetermined location. | 05-14-2009 |
| 20100288556 | Ice Drill - A device is designed for optionally connecting a crank ( | 11-18-2010 |
| 20120318577 | POWERED AND MANUAL AUGER - Apparatus and methods for drilling a hole. A hybrid powered and manual auger is disclosed. The auger may include one or more cutting blades coupled to a drive shaft driven by a motor. The auger may further include a manual crank configured to rotate the motor and the drive shaft about a drive axis. The manual crank comprises a U-shaped offset formed by an upper crank arm and a lower crank arm joined by a crank handle portion. The drive shaft can be rotated by the motor alone, by rotation of the manual crank alone, and by a combination of the motor and rotation of the manual crank. | 12-20-2012 |
| 20140174824 | ELECTRIC AUGER - An electric auger including an auger assembly with a coupling assembly at a proximal end, a cutting assembly having at least one cutting blade located at a distal end, and a helical flight located between the proximal end and the distal end. The electric power head includes an A/C motor with a drive shaft configured to mechanically couple with the proximal end of the auger assembly. An on-board 36-volt DC battery pack powers the A/C motor. A controller includes an inverter that converts DC power to A/C power for the A/C motor. The ratio of cubic inches of ice cut per battery ampere-hour per weight in pounds of the electric auger is at least about 900 (inches | 06-26-2014 |
| 20150361724 | ICE DRILL - An ice drill. The ice drill includes a power head. The power head is configured to allow the user to control operation of the ice drill. The ice drill also includes an engine. The engine includes a propane carburetor. The propane carburetor includes a plunger valve. The plunger valve includes a body, a set of flutes on the body, and a tip. The ice drill further includes a cutting blade. The cutting blade configured to be moved by the engine to create a hole in ice. | 12-17-2015 |
| 20160010393 | Ice Auger Assembly Incorporating an Ice Reaming Blade | 01-14-2016 |
