Patent number: 9416514Abstract: The post driver with limited movement floating post anvil does not rely heavily upon the skill of the operator to efficiently drive posts. The post anvil is allowed to move up and down in relation to the driver, but its movement is limited by both lower and upper fixed barriers. Since the movement is limited, the operator can position the driver upon the post allowing the full weight of the driver framework/carrier machine to rest upon the post. The post would push the floating post anvil upward only to the point at which the upper fixed barrier prevents further upward movement of the floating post anvil. Thus, once the floating post anvil abuts the upper fixed barrier, substantially the entire weight of the post driver is resting on the post.Type: GrantFiled: January 29, 2013Date of Patent: August 16, 2016Assignee: DANUSER LLCInventors: Gary J Niekamp, Tyler Van Lant

Patent number: 9238895Abstract: The post driver machine includes a housing, inside of which is a weight which can be lifted by a chain being rotated around a generally elliptical path by a powered sprocket. A catch mechanism is affixed to the chain, and can engage with a weight catch attached to the weight. However, when there is not a post positioned within the post driver, the weight rests at a position too low the weight catch to engage with the catch mechanism. Upon properly inserting a post into the post driver, the post presses upwardly on the weight until the weight catch engages with the catch mechanism to lift the weight.Type: GrantFiled: January 29, 2013Date of Patent: January 19, 2016Assignee: DANUSER LLCInventors: Gary J Niekamp, Tyler Van Lant

Publication number: 20120090896Abstract: An auger for digging holes that minimizes the amount of loose dirt excavated in and around the dug hole. The auger comprises an elongated shaft body whose axial longitudinal center is disposed in a parallel offset position from the axial engagement line of orientation with the driving source for rotationally driving the auger. The shaft body of the auger revolves in an eccentric lateral orbit as the auger rotates which digs the hole by pushing and widening the dirt in the hole rather than cutting and scraping. The distal end of the auger has a tapered configuration for initial penetration into the ground. The eccentric movement of the shaft body of the auger helps to compact the walls of the hole being dug.Type: ApplicationFiled: October 13, 2011Publication date: April 19, 2012Applicant: DANUSER LLCInventor: Gary J.
