The auger may also include an air induction unit 66 including an air-receiving opening in the T-shaped handle; an air-line 60 positioned within a hollow of the shaft connecting the air-receiving opening with air exhaust openings so as a jet of the air can blow out of said auger to break up and blow away the drilling detritus. | ||||||
| 62 | Post hole digger | US12484280 | 2009-06-15 | US08061744B2 | 2011-11-22 | Josef E. Domian |
| A post hole digger includes a pair of blades that face one another, a pair of shaft handles attached to the blades, and a pivot member that pivotally couples the shaft handles together. A pair of gripping handles are attached to, and are generally perpendicular to, the shaft handles, which provides a second gripping location for the user and enhances the ability to thrust and rotate the tool in the ground. The blades are off-set by at least ¼ inch from each other in order to improve a user's ability to rotate the post hole digger and remove soil from the hole. The blades include an angled distal edge, which has a leading edge portion, an intermediate edge portion and a trailing edge portion. The leading edge extends downwardly further than the intermediate portion, which in turn extends downwardly further than the trailing edge portion. | ||||||

| This invention provides a post hole digger having a first, traverse pivot point, located on the lower section of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members. | ||||||

| 73 | Hole cleaning and/or forming tool | US10496307 | 2002-11-25 | US07191853B2 | 2007-03-20 | Graeme D Maher; Edward A Kelly |
| A tool for cleaning and/or forming holes, the tool having a shaft, the shaft having a lower end and at least two buckets attached adjacent to the lower end of the shaft, each bucket having an open mouth which extends radially from the axis of the shaft, consequently rotation of the shaft about its axis causes rotation of the buckets, causing dirt to pass through the mouth of each bucket. | ||||||
| 74 | LATERAL BORING SYSTEM | US10710136 | 2004-06-21 | US20050279531A1 | 2005-12-22 | Anthony Schelling |
| A lateral boring device for effective utility installation under sidewalks, driveways, and other obstacles. The present invention utilizes a hand-held drill, a flexible shaft, a blade attachable to the flexible shaft, and a metal sock. The operator of the present invention makes an incision into the ground with the blade in close proximity to the obstacle intended to be circumvented. The operator commences boring, and the flexible shaft begins to descend below the ground and underneath the obstacle. The low power of the drill prevents the flexible shaft from continuing to descend below the hardpan, and cause the flexible shaft to bend in a generally upwardly horizontal direction. The low power of the drill also prevents the flexible shaft or the blade from causing damage to the underside of the obstacle, and eventually the flexible shaft resurfaces on the opposite side of the obstacle. Upon resurfacing, the operator removes the blade and attaches the sock, which can be coupled to the length of wire, pipe or conduit and pulled back through the bore hole. | ||||||
