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.

6955227 - Auger for mixing and burrowing - Owned by Versatile Housewares (Cambridge, WI)

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.

6454669 - Annulus golf tee with removable penetration cone

A dime-sized annulus top end is provided for a golf tee. Also provided for the golf tee is a removable penetration cone which is a piece of stiff material with a pointed end for inserting into ground and an open hollowed end for receiving and securely holding a golf tee point. The annulus rim golf tee and removable penetration cone, while simple and unobtrusive, stabilize a teed golf ball, reduce re-teeing, and provide easy tee-insertion into all terrain.

7150238 - Bulber with dirt release mechanism - Owned by Helen of Troy Limited (St. Michael,BB)

A handheld bulber for use in planting and gardening is disclosed. The bulber has a rigid steel inverted conical frustum body of at least two opposing and slightly overlapping sidewall members pivotably joined together and a handle attached opposite a serrated cutting edge of the body. A movable dirt release mechanism is positioned between the handle and the pivot point such that moving the mechanism toward the handle, i.e., a squeezing hand motion, forces the handle end of the side members inward, thereby pivoting the digging end of the sidewall members outward. The dirt release mechanism may be attached within the slotted openings by a slider, rollers, or any other suitable means.
