  • Patent number: 6289986
    Abstract: A pump rod drive and torque release mechanism for use in association with a downhole pump positioned within a well. The pump rod drive and torque release mechanism comprises a central housing having a generally hollow interior, a drive shaft received within the central housing, a drive rod received within the central housing, and a torque transfer mechanism positioned within the central housing. The drive shaft may be operatively connected to a pump rod rotator to impart rotational movement to the drive shaft. The drive rod may be operatively connected to a downhole pump so as to enable transference of rotational energy from the drive rod to the downhole pump. The torque transfer mechanism has an engaged position wherein it operatively connects the drive shaft to the drive rod such that rotation of the drive shaft causes rotation of the drive rod. The torque transfer mechanism also has a disengaged position wherein it operatively disconnects the drive shaft from the drive rod.
