  • Patent number: 9163382
    Abstract: The gearbox lock mechanism for a post bole auger has a collar coupled to a lower end of a right angle gearbox, the collar rotatable upon operation of the gearbox. The collar comprises a semi-circular outer edge and a fiat side. A male-threaded nipple extends from the collar and threads onto the auger shaft. A lock bar is coupled to the gearbox and acts as a positive lock to lock the collar in place for removal of the shaft from the gearbox. The lock bar is rotatable from a locked position whereby the lock bar is aligned with and contactable with the flat side of the outer edge of the collar, to an unlocked position whereby the lock bar does not contact the flat side of the outer edge of the collar.

  • Patent number: 6932163
    Abstract: A saw (10) facilitates cutting of roofing and includes a frame (12) that is mobile on a work surface. A locking mechanism (40) locks the frame (12) into a transport position. Actuating a release lever (60) allows the frame (12) to be adjusted into a working position. A shaft (14) rotatably mounted by first, second and third bearings (74, 75, 76) has saw blades (16, 18) and a pulley (77) for connection with a drive belt (80). The drive belt (80) passes through a hole (79) in the frame (12) to connect to a drive (81) to rotate the shaft (14) and the saw blades (16, 18). The third bearing (76) is mounted to a bearing support (85). The frame (12) has a gap (84) communicating the hole (79) with an exterior edge (78) of the frame (12) proximate the third bearing (76), with the bearing support (85) removably and replaceably mounted to the frame (12) and spanning the gap (84).

  • Patent number: 5507354
    Abstract: A post hole digger for attachment to the three-point hitch of a tractor comprises a mainframe having a position control/lock down assembly mounted thereto for raising and lowering the frame and securing the frame to the tractor. A pair of bipartite booms having first and second angled arms are pivotally mounted to the frame. A drill assembly is swingably mounted to a cross beam extending between the second boom arms of each boom. A pair of cylinders extending between the first boom arms and frame pivots the boom arms into and away from a ground drilling position. During the drilling process the bipartite boom configuration compensates for the tendencies of the drill to divert from a true vertical line. The driller transfers the weight of the tractor to the boom arms and the drill connected thereto so as to effectively drill holes in rock-laden soils.

  • Patent number: 4308923
    Abstract: Disclosed herein is a device for orienting a drilling auger disposed on and powered by a vehicle defined by a lower frame member carried by the vehicle, an upper frame member pivoted to the lower frame member for rotation about an axis, and an auger supporting framework pivoted to the upper framework for rotation about a second axis orthogonal to the first axis in which the rotation is controlled by hydraulic cylinders extending between the lower and upper frame members, and between the upper frame member and the auger supporting framework, respectively. The auger itself is driven by a power take-off on the vehicle in a preferred form which in conjunction with the preceeding structure allows the auger to address the earth in which the hole is to be drilled in substantially any angle above the surface of the earth.

  • Patent number: 4116284
    Abstract: An earth auger arrangement wherein a power source is mounted on wheels for moving the power source over the earth's surface with means connected to the power source for relaying power to a transmission with which an auger is connected. Handle means are connected to the transmission for manually positioning the auger in relation to the earth's surface to penetrate it at a desired angle with throttle means on the handle means to control the power source. Shaft means are pivotally connected to and extend between the power source and the handle means to reduce counter rotation or counter torque from being exerted on the operator when the auger is rotated to penetrate the earth.
