  • Method of liveloading a rotary or reciprocating shaft packing
    Patent number: 5097595
    Abstract: A liveload assembly including a stack guide, compressed belleville washers stacked inside the stack guide and a retainer to hold the compressed washers in the stack guide. A longitudinal slot in the wall of the stack guide permits visual checking of the compression provided by the liveload assembly on the gland follower of the valve or pump. The rotary or reciprocating shaft of a valve or pump is liveloaded by placing the liveload assembly over the bolt securing the gland follower to the stuffing box. A nut is threaded on the bolt until it contacts the washers and the retainer removed.

  • Auxiliary workover rig
    Patent number: 4684306
    Abstract: An auxiliary rig is used in combination with a primary drilling or workover rig. The primary drilling rig typically includes an elongated upstanding drill tower, a base and a crown block. The auxiliary rig of the present invention includes a racking tower detachably mounted with the upper end of the drill tower to form an extension to the drill tower for receiving interconnected pairs of tubular members to reduce the tripping time of the tubular members into and out of the well. A movable slip and controller therefor of the auxiliary rig are operably guided by the racking tower for releasably supporting the pairs of tubular members.
