Patent number: 11885223Abstract: An apparatus and method for preventing drill string drag. Rotation encoders are provided for tracking the rotation of an inner and outer member of a dual-member drill string. Based upon the drilling conditions, the readings of the encoder can detect when the inner member is dragging on the outer member. When such a drag condition is detected, a processor can trigger remedial measures, which may include increasing a rotation rate of the inner member, sending a warning signal, stopping operation, or a combination of these.Type: GrantFiled: October 16, 2020Date of Patent: January 30, 2024Assignee: The Charles Machine Works, Inc.Inventors: Greg L. Slaughter, Jr., Joseph G. Greenlee, Joe Glenn Worlow

Patent number: 11828176Abstract: A pipe assembly used in horizontal directional drilling operations. The pipe assembly has an outer member, an inner member, and first removable collar. The inner member has a polygonal outer profile of uniform shape along its length and is partially contained within the outer member. The first removable collar is supported on the inner member within the outer member and limits relative axial movement of the inner member and the outer member.Type: GrantFiled: May 10, 2021Date of Patent: November 28, 2023Assignee: The Charles Machine Works, Inc.Inventors: Greg L. Slaughter, Jr., Joseph G. Greenlee

Publication number: 20230332487Abstract: A brake system for maintaining an angular position of a spindle assembly. A pump-powered motor drives rotation of a spindle on the machine. When no rotation is desired, the spindle will slow, then stop at a desired angular orientation. A rotational sensor will determine the clock position, and a controller compares that to a desired angular orientation. If an error tolerance is exceeded, the motor will rotate the spindle back to the desired orientation.Type: ApplicationFiled: June 26, 2023Publication date: October 19, 2023Inventors: Joseph G. Greenlee, Aleksander S. Wolfe, Jarred R. Callaway, Max A. Metcalf

Publication number: 20230193701Abstract: A system for connecting a drill bit and pipe puller to a drill string. The system includes a downhole tool having an internal cavity and a through-hole in its wall. A coupler may be slidingly received in the cavity and connected using one or more fasteners which interconnect a groove in the coupler to the wall of the downhole tool. Fasteners used may be screws or bolts interconnecting the wall of the tool with radial holes in the coupler. Alternatively, bolts may interconnect the wall with a circumferential groove on the coupler. A drill bit may be threaded into the coupler. The coupler allows drill bits and other tools to be connected and disconnected from a downhole tool without unthreading the drill bit.Type: ApplicationFiled: February 13, 2023Publication date: June 22, 2023Inventors: Greg L. Slaughter, JR., Travis W. Woodson, Joseph G. Greenlee
