Abstract
An auger to assist in ground-burrowing or mixing paint or concrete, is used by attaching it to an electric or cordless power source. The major advantages over previous augers are: a hex head design prevents slipping in the drill chuck, an offset boring tip provides better digging, and a removable extension allows for the digging holes from a sitting or standing position possible without straining. The cutting edge of the auger's discs is sharpened for easier digging in hard soil. A single spring pin lock connects a first shaft to the extension shaft.
Claims14
A device for attachment to a power source to bore a hole in soil comprising:
- a) a first shaft having a first end and a second end;
- the first end including a hexagonal-shaped portion, the second end including a pointed tip offset from center and shaved flat on one side at an angle configured for boring a hole in the soil, wherein the pointed tip has a cavity therein;
- b) a disc attached a distance from the second end;
- and
- c) a second shaft, longer than the first shaft, having a first end and a second end and wherein:
- 1) the first end is hexagonal-shaped;
- and
- 2) the second end has a first shaft receiving portion with a bore therein;
- and
- d) a U-shaped pin removable with a finger and used for affixing the first shaft to the second shaft.
A device for use in combination with a power source for boring a hole in soil comprising;
- a) a power drill with chuck jaws;
- and
- b) an auger attached to the power drill comprising:
- 1) a first shaft comprising:
- i. a first hexagonal end,
- ii a second end opposite the first end having a sharpened tip with a shallow cavity and thin outside edges, and
- iii. a hole near the first end configured to receive a pin;
- 2) a second shaft connected to said first shaft comprising;
- i. a first hexagonal end,
- ii. a second end opposite the first end and including a receiving portion configured to receive the hexagonal first end of the first shaft, and
- iii. a hole on the receiving portion aligned with the hole of the first end of the first shaft configured to receive a pin;
- 3) a single U-shaped cotter pin configured to be inserted through the holes on the first and second shafts;
- and
- 4) a spiral disc attached near the tip of the first shaft comprising a leading edge and a trailing edge.
