Latest Patents

Mitchhart's latest patent focuses on a drill pipe handling mechanism designed for drilling rigs. This mechanism features spaced apart upper and lower arms mounted on a shaft, allowing for pivotal and limited axial movement. The lower arm includes a receptacle for the lower end of a drill pipe section, while the upper arm is equipped with a drill pipe holder that has a power actuated movable gate section. Additionally, a drill pipe retainer is pivotally mounted on the shaft above the pipe holder and is operated by a separate power actuator. The design also incorporates opposed power actuated pipe gripping and holding wrenches, which are strategically placed on the lower part of the rig mast. These wrenches grip and hold a drill pipe section while threaded joints are broken loose by a rotary head connected to the upper end of the drill string. Furthermore, a power actuated wrench is mounted for pivotal movement into pipe gripping position, specifically for breaking loose threaded joints that cannot be loosened by the rotary head.
