Publication number: 20130243530Abstract: The present invention relates to a pipe handling assembly for use with a rod pushing and pulling machine in pipe bursting and pipe replacement operations. The assembly uses a rod transport assembly to transport a rod from a vertical receiving position to a horizontal receiving position. A rod transfer assembly then axially advances the rod in a horizontal receiving position to the rod pushing and pulling machine where the rod can be incorporated into a drill string. The rod handling assembly also can be used for transporting rods out of an excavation pit after they have been broken off from a rod string by a rod pushing and pulling machine.Type: ApplicationFiled: January 26, 2012Publication date: September 19, 2013Applicant: Earth Tool Company LLCInventors: Brian John Bischel, Walter George Thompson

Patent number: 6554082Abstract: An apparatus and method for controlling an underground boring machine during boring or reaming operations. A boring tool is displaced along an underground path while being rotated. In response to variations in underground conditions impacting boring tool progress along the underground path, a control system modifies the rate of boring tool displacement along the underground path while rotating the boring tool at a selected rotation rate to optimize excavation productivity. The controller may also monitor the rate at which liquid is pumped through the borehole and automatically adjust the rate of displacement and/or the liquid flow rate so that sufficient liquid is flowing through the borehole to remove the cuttings and debris generated by the boring tool.Type: GrantFiled: April 22, 2002Date of Patent: April 29, 2003Assignee: Vermeer Manufacturing CompanyInventors: Brian John Bischel, James Richard Rankin

Patent number: 6497296Abstract: A horizontal directional drilling machine for generating a bore with a drill string. The machine includes a frame defining a thrust axis. A rotational drive head for rotating the drill string is mounted on the frame. A thrust mechanism is provided for moving the rotational drive head in a first direction along the thrust axis to push the drill string into the ground, and a second direction along the thrust axis to pull the drill string from the ground. The horizontal directional drilling machine also includes an anchoring arrangement connected to the frame. In one embodiment, the anchoring arrangement includes a stake-down unit that is pivotally movable about a pivot axis that is generally transversely oriented relative to the thrust axis. The stake-down unit includes a power auger, and a stake-down actuator for moving the power auger toward and away from the ground. The anchoring arrangement also includes a tilt actuator for pivoting the stake-down unit about the pivot axis.Type: GrantFiled: June 5, 2000Date of Patent: December 24, 2002Assignee: Vermeer Manufacturing CompanyInventors: Michael Lee McGriff, Brian John Bischel

Patent number: 6289997Abstract: An apparatus and method for controlling an underground boring machine during boring or reaming operations. A boring tool is displaced along an underground path while being rotated at a-selected rate of rotation. In response to variations in underground conditions impacting boring tool progress along the underground path, a control system concurrently modifies the rate of boring tool displacement along the underground path while rotating the boring tool at the selected rotation rate. The controller monitors the rate at which liquid is pumped through the borehole and automatically adjusts the rate of displacement and/or the liquid flow rate so that sufficient liquid is flowing through the borehole to remove the cuttings and debris generated by the boring tool. Sensors are provided to sense pressure levels in the rotation, displacement, and liquid dispensing pumps and an electronic controller continuously monitors the levels detected by the sensors.Type: GrantFiled: June 28, 2000Date of Patent: September 18, 2001Assignee: Vermeer Manufacturing CompanyInventors: Brian John Bischel, James Richard Rankin
