Auger Type Patents (Class 111/116)
  • Patent number: 7258178
    Abstract: An auger planter for forming small holes in the earth for the planting of flower bulbs, plant seedlings and plants, and for the insertion of termite monitors and baits. The auger includes a central shaft and a single helical flighting having its leading edge configured to have a sickle blade shape with a cutting edge. The opposite end of the flighting has a portion which is directed in an essentially vertical orientation proximating an alignment parallelling the axis of shaft.

  • Patent number: 6296068
    Abstract: A planting system with the special planter to dig uniform holes, puck type plant feeders to go in the holes and plastic dual planting trays. These can be used independently or in any combination. Features include a protective shroud, pulverizing the dirt by circulating it in an enclosed area, a tapered spiral ramp to help pile the dirt and pulverize it, a root cutter, ground clearing with spinning shroud, a friction plate to power ground clearing, pointed feet at the bottom of the shroud to stop the spinning when excavation starts, a rock sifter including a ramped face on the internal louvers, a rock catcher ring with flexible fingers, piling the dirt around the perimeter, hole depth measurement rings on the shaft, a slidable ring to select gap between the bottom of the shroud and the ground and an optional locking stop ring to guarantee uniform hole depth.

  • Patent number: 6125776
    Abstract: A device for digging holes for setting out bedding plants, including a rotary tool for digging a hole, the tool having a shank adapted to be chucked to a power drill and passing through an inverted bowl shaped transparent plastic cover to contain excavated soil and dispose the same in an annular mound, for ready repacking of the soil around the plant roots. A limit stop arrangement limits the extent of advance through the cover which rests on the ground during the use of the device, so as to set the hole depth. The tool has a flat bladed digging portion forming a flat bottomed hole.

  • Patent number: 5564353
    Abstract: A planting hole forming apparatus includes a central shaft having a longitudinal axis, a bottom leading end and an upper trailing end, and a discontinuous flighting comprising a plurality of flighting sections spiraling around the central shaft at spaced locations along the shaft adjacent the bottom leading end. Some form of drive mechanism, for example a hand-held drill, is used to rotate the central shaft about its longitudinal axis to thereby form the planting hole. The drive mechanism is chosen to accommodate the size of the central shaft and to supply the necessary torque to rotate the central shaft sufficiently to form the planting hole. The structure of the flighting sections is such that while the planting hole is being formed the soil is simultaneously pulverized with a substantial portion of the pulverized soil being left in the hole.

  • Patent number: 5540433
    Abstract: A golf tee drill comprising a cylindrical casing having a removable cap at a first end. A spring is mounted in the removable cap. An electric motor is provided, having a rotatable shaft. The motor is secured within a second end of the casing. A battery is within the casing between the spring and the motor. A switch is on the casing and is electrically connected between the motor and the battery. An auger drill bit is also provided, having a cone shaped collar. A coupling assembly is for attaching the auger drill bit at the cone shaped collar to the shaft of the motor. When the switch is turned on, the auger drill bit will rotate to penetrate hard ground and form a pilot hole for setting a golf tee therein.

  • Patent number: 4901800
    Abstract: The tool includes a shaft adapted at its upper end to receive a power source. Flighting extends partially along the shaft above a pair of radially directed elongate blades which project outwardly from the shaft a distance beyond the flighting edge. A modified form dispenses with the flighting.
