Abstract: An electro-hydraulically operated tool apparatus installs and removes bolts of track shoes for assembling and disassembling endless track assemblies. In the assembly procedure, a wrench of the tool apparatus engages the head portion of a track shoe bolt and rotates the bolt in a clockwise direction at a relatively high speed to thread a nut onto the bolt and secure the track shoe to the track chain. The tool apparatus senses the torque and at a pre-set level, a transmission of the apparatus automatically shifts to rotate the wrench at a relatively low speed. At this point, the tool apparatus starts measuring the angle of rotation, and at a pre-determined angle of about 120.degree., the wrench stops rotating. The rotation of the bolt an additional 120.degree. after the pre-torque level is reached applies the desired torque value to the bolted joint. In the disassembly procedure, the wrench engages the head portion of the bolt and applies a large down pressure to the bolt.

Abstract: A gear drive used in water well drilling or blast hole drilling to remove overburden in open pit coal mining, not only rotates the drill pipe but also pulls down or pulls out the drill pipe as it rotates. A hydraulic motor within a housing operates a first gear train to rotate an output shaft at varying speeds. A drill pipe is projected through the output shaft. A plurality of feed rollers are mounted on spherical bearings, the outside diameter of the rollers having a concave recess for operative registry with the drill pipe. When the output shaft is rotated, each roller cocks and digs into the feed pipe causing it to rotate with the output shaft. The pull down and pull up section is driven by a hydraulic motor within the housing through a second gear train. The second gear train drives a plurality of third gear trains for individually driving the respective feed rollers.

Abstract: A drill rig for drilling wells having a derrick adapted to hold and lower a conductor string and drill pipe string. A support frame is fixed to the derrick to extend over the well to be drilled, and a rotary table, for holding and rotating drill pipe strings, is movably mounted thereon. The table is displaceable between an active position in alignment with the axis of the well and an inactive position laterally spaced therefrom. A drill pipe holder is movably mounted on the frame below the rotary table for displacement between a first position laterally of the axis of the well and a second position in alignment with the axis of the well. The rotary table and said drill pipe holder are displaced in opposition to each other, so that the rotary table may be removed from alignment with the axis of the well and said drill pipe string simultaneously held without removal from said well.

The rotating center is located inwardly of the shoe. A bearing member has a fixed housing and a rotating center member. The fixed housing is attached to the shoe by a circumferentially extending wall member while the center member rotates with and slidably receives the kelly therethrough.The kelly can be lifted from the kelly bushing carrying the guard therewith so that the floor is unobstructed and the inner slip bowl is free to receive a set of slips or the like.

Abstract: A flexible shaft is formed of a plurality of linked sections which lock together to provide a rigid shaft when turned in a first direction as for drilling and which, when turned in the opposite direction, unlatch, thereby permitting limited relative movement of the sections so that they may follow a curved path for storage. As the sections are rotated in the first direction, certain internal notches of one section and mating external projections of the next section tend to wedge together and then do not always separate easily and readily when the torque on the shaft is reversed.

The outer shell is comprised of an upper smaller shell section which is mountable on the kelly bushing itself, there being provided an upper opening through the upper shell portion allowing the passage of the kelly therethrough. A lower shell section is integrally attached to the upper shell section, the lower shell section coverably registering with and guarding the rotary table portion of a well drilling apparatus. An improved cushioned mounting is provided which can be in the form of a plurality of pliable rubberized rings. The larger lower shell section provides a free space under the upper shell section which free space allows the kelly bushing to freely rotate therewithin.

Abstract: In raise bore drilling, a drill string of non-round cross-sectional configuration is connected through a pilot hole from a raise bore bit at the lower end of the pilot hole to a raise bore drilling rig at the upper end of the hole. The drill string is defined by a number of serially connected individual pipe lengths. The drill string configuration preferably is hexagonal except at one end of each length where the pipe length is round for a distance which corresponds to the length of a female threaded connection component defined by that end of the pipe length. The other end of each pipe length defines a cooperating male threaded connection component.

Abstract: A system for testing and installing a blow out preventer on a floating vessel and offshore drilling rigs, although the system may be used on other rotary drlling rigs, is disclosed. Retractable rotary table supporting beams are disposed over the moon pool and the rotary table is releasably connected to them. Retractable sub-structure beams are provided below the rotary table so that means provided to move the assembled blow out preventer can move it through an opening in the derrick and over the moon pool when the rotary beams are retracted. Retractable moon pool skid beams are provided which support the blow out preventer when skidded through the moon pool opening in the sub-structure.

Abstract: A raise bore drilling rig is provided for use with a drill string of non-round cross-sectional configuration; the drill string is connectible through a pilot hole from a raise bore bit at the lower end of the pilot hole to the raise bore drilling rig at the upper end of the hole. To enable simple assembly of the drill string, the upper end of each length of drill string is circular in way of the female component of a threaded coupling. The drilling rig includes a rotary drive mechanism which mates with the non-round cross-section of individual lengths of drill string and which is rotatably driven to apply torque to the drill string as it is raised axially during the raise bore drilling process. The torque applying component of the drilling rig which is directly engageable with the drill string includes a vertically floating "bushing" which enables torque to be applied to the string as a coupling is raised through a normal "at rest" position of the bushing.
