Title: Joseph G. Greenlee: Innovator in Drilling Technology

Introduction

Joseph G. Greenlee is a notable inventor based in Perry, Oklahoma, with a remarkable portfolio of 12 patents. His contributions to the field of drilling technology have significantly advanced the efficiency and functionality of drilling operations.

Latest Patents

Among his latest innovations is the "Dual Pipe Drill Head Quick Interchange Joint." This system is designed for connecting a drill bit and pipe puller to a drill string. It features a downhole tool with an internal cavity and a through-hole in its wall. A coupler can be slidingly received in the cavity and connected using fasteners that interconnect a groove in the coupler to the wall of the downhole tool. The fasteners may include screws or bolts that connect the wall of the tool with radial holes in the coupler. Alternatively, bolts may connect the wall with a circumferential groove on the coupler. This design allows drill bits and other tools to be connected and disconnected from a downhole tool without the need to unthread the drill bit. Another significant patent is the "Virtual Brake System," which maintains the angular position of a spindle assembly. This system utilizes a pump-powered motor to drive the rotation of a spindle on the machine. When no rotation is desired, the spindle slows and stops at a predetermined angular orientation. A rotational sensor determines the clock position, and a controller compares it to the desired orientation. If the error tolerance is exceeded, the motor rotates the spindle back to the desired position.
