Abstract: A clamping mechanism having two or more jaws which may be opened to allow a tubular to be introduced within the jaws and closed to retain the tubular therewithin. The rollers are located within concave recesses and maintained in spaced apart relationship by biasing means, whereby rotation of tubular may cause the rollers to be wedged between a wall of the recess and the tubular to grip the tubular within the jaws. The clamping mechanism may be utilized as an oil field tubular clamp, a slip, a pipe clamp, and other mechanisms. There is also disclosed a clutch comprising an outer race, a cage, and an inner ring. Recesses are provided in an outer race and accommodate rollers therewith and maintained in spaced apart relationship by the cage. The cage may be moved by an actuator to selectively allow free wheeling or prevent rotation. A socket ratchet incorporating such a clutch is also disclosed.

Abstract: A nut capturing socket assembly includes a socket, an inner sleeve and an outer sleeve.

The inner sleeve has a non-circular shaped opening at an opposite end of the same size and configuration as the non-circular shaped interior opening of the socket. A first abutment element is fixed relative to the socket and a second abutment element is fixed relative to the inner sleeve. An elastic element is positioned between the first and second abutment elements to bias the inner sleeve rotationally relative to the socket. The outer sleeve surrounds the inner sleeve is sized to engage the inner sleeve to co-rotate therewith. The outer sleeve captures the elastic element internally of the socket assembly.

Abstract: An adjustable ratchet head assembly has first and second jaw members that are connected using a pinion shaft and a cogwheel shaft. The pinion shaft has oppositely threaded end portions that engage oppositely threaded pinion shaft receiving bores in a central section of each jaw member. The cogwheel shaft has oppositely threaded end portions that engage oppositely threaded cogwheel shaft receiving bores in a proximate end of each jaw member. A pinion gear is concentric with and engages the pinion shaft. A cogwheel gear is concentric with and engages the cogwheel shaft, and is in driving engagement with the pinion gear. Driving the cogwheel gear will cause rotation of the cogwheel shaft, pinion gear and pinion shaft, and will cause the jaw members to move toward or away from each other. The ratchet head assembly is received in a cylindrical ratchet head body, which is received in a handle assembly.

Abstract: A ratcheting tool such as a reversible dual-pawl ratchet wrench is disclosed that minimizes wasted motion during ratchet slip or counter-rotation. The ratchet wrench includes a bias assembly that biases the pawls apart to bias a first, selected pawl for a selected drive direction towards engagement with a ratchet gear, and that the biases the selected pawl into a concentric alignment with the ratchet gear. In this manner, non-ratcheting initial rotation of the pawl due to counter-rotation prior to the pawl camming out of engagement with the ratchet gear is eliminated, thus eliminating wasted motion and maximizing the available angular sweep for the wrench.

Abstract: A ratchet wrench includes a head and a handle interconnected to the head. The head includes a first compartment rotatably receiving a drive member. Two pawls are slideably received in a compartment of the head. A switch is slideably received in a third compartment of the head between first, second, and third operative positions to change the driving direction of the ratchet wrench. An actuator is slideably received in the second compartment and includes two guiding portions selectively engaged with one of the pawls when the switch is in one of the first and second operative positions. The pawls are disengaged from the guiding portions and engaged with the drive member when the switch is in the third operative positions, allowing the handle and the drive member to rotate in either of two directions driving a fastener, and not allowing free rotation of the handle relative to the drive member in either of the two directions without driving the fastener.

Abstract: A tool includes a first and a second socket wrench pivotally turnably connected to two ends of a link. Each of the first and second socket wrenches includes a wrench portion and a circular end portion having an axial slot extended through them. The wrench portion of the first socket wrench is internally formed of a hexagonally shaped portion for fitting around a hexagonally-shaped outer surface of a connecting ring of a male F connector to tighten or loosen the connecting ring to or from a female F connector, and the wrench portion of the second socket wrench is internally formed of a constant-torque shaped portion for fitting around the hexagonally-shaped outer surface of the connecting ring to prevent the tool from applying an excessive torque on the connecting ring when turning the same. The tool can be used without being hindered by bent or closely arranged cables.

Abstract: A gripping apparatus and a method apparatus for making up and breaking out tubular connections. In one embodiment, the gripping apparatus comprises an outer gear, a plurality of rollers coupled to the outer gear, an inner ring, a passive jaw, and a pair of active jaws pivotably coupled to the inner ring. The active jaws include camming surfaces for positioning, securing, actuating, and retracting the active jaws upon rotation of the outer gear. The gripping apparatus may further include a control switch operable to maintain the gripping apparatus in a make up mode or a break out mode regardless of rotation of the outer gear.

Abstract: A dual screwdriver is provided for connecting and disconnecting a connector assembly having first and second jackscrew guideposts. In one embodiment, the dual screwdriver includes a housing, a user input rotatably coupled to the housing, first and second manually-bendable shafts each rotatably coupled to the housing, and first and second bits mounted to the distal end portions of first and second manually-bendable shafts, respectively.

Abstract: The problem of reaching a work piece, such as a nut on a bolt, in a restricted space not permitting traditional means of applying torque is addressed with a powered wrench. The wrench translates motor power on one axis to an engageable socket on a perpendicular axis through an innovative gearbox. Means are provided to shift from a gear ratio for power to a gear ratio for speed by simple manipulation, while different size work pieces can be accommodated through socket change parts.
