Abstract: An apparatus for removing a nut is described. The apparatus includes a housing, a cage, and a canted coil spring. The housing has a top surface, an interior sidewall, and a bottom surface. The interior sidewall defines an orifice that extends from the top surface to a lip. The interior sidewall includes a three-lobed cam and a groove. Each lobe has a lobe center line, a counterclockwise cam inner surface on one side of the lobe center line, and a clockwise cam inner surface on the opposite side of the lobe center line. The canted coil spring is received by the groove of the interior sidewall and the groove of the cage. The canted coil spring rotatably couples the cage to the housing. During nut removal, the housing rotates counterclockwise relative to the cage. The cage rotates counterclockwise to engage the nut, and the cage interfaces with the interior sidewall.

Abstract: An apparatus for removing a stud is described. The apparatus includes a housing, a cage and a canted coil spring. The housing has an interior sidewall with a three-lobed cam and a groove. Each lobe has a counterclockwise cam inner surface and a clockwise cam inner surface on the opposite side of the lobe center line. The cage has a top surface, a tapered terminus and a groove disposed between the top surface and the tapered terminus. The cage includes a plurality of jaws, in which the jaw outer cam surface of each jaw interfaces with the cam inner surface of the interior sidewall. The canted coil spring rotatably couples the cage to the housing. During stud removal, the housing rotates counterclockwise relative to the cage and the cage rotates counterclockwise to engage the stud.

Abstract: An apparatus for removing a socket fastener is described. The apparatus includes a base, a camshaft, a sleeve and a cartridge. The base includes a base top section and a base bottom section. The camshaft includes lobes that extend from a camshaft top surface to a camshaft bottom surface. The camshaft is fixedly coupled to the base. The cartridge includes a cartridge top surface, a cartridge lip and a plurality of jaws. Each jaw includes a jaw counterclockwise outer cam surface, a jaw counterclockwise inner cam surface, a jaw clockwise outer cam surface, and a jaw clockwise inner cam surface. The cartridge is fixedly coupled to the sleeve and the cartridge interfaces with the camshaft. Additionally, the jaw inner cam surface interfaces with the camshaft cam profiles. The jaws rotate and engage the socket fastener.

Abstract: An apparatus for removing a fastener having a cylindrical aperture is described. The apparatus includes a base, a camshaft, a sleeve and a cartridge. The camshaft includes lobes that extend from a camshaft top surface to a camshaft bottom surface. The cartridge includes a cartridge top surface, a cartridge lip and a plurality of jaws. Each jaw includes a jaw counterclockwise outer frictional surface, a jaw counterclockwise inner cam surface, a jaw clockwise outer frictional surface and a jaw clockwise inner cam surface. The cartridge is fixedly coupled to the sleeve and the cartridge interfaces with the camshaft. Additionally, the jaw inner cam surface interfaces with the camshaft cam profiles. The jaws rotate and engage the walls of the fastener cylindrical aperture.

Abstract: A carriage system supports an impact or driver tool. The carriage system has a support member that extends upwardly from a base platform. Support arms are rotatably connected to the support member at medial portion of the arms at different elevations above the support member. A proximal end of each of the arms rotatably connects to a weight, while a distal end of each of the arms is adapted to rotatably connect to the driver tool. The weight is located on an opposite side of the support member from the driver tool when the driver tool is attached. When the weight is moved in a vertical direction, the arms rotate in combination with the movement of the weight. The arms rotate about their respective medial connections, thereby forcing the ends that rotatably connect to the driver tool to move in a vertically opposite direction than the weight.

Abstract: A tool has a member that inserts into a bore formed in a threaded workpiece to grip and rotate the workpiece. The tool has a head having a polygonal socket for insertion of a drive member. A shank extends from the head for insertion into the bore of the workpiece. The shank has cam surfaces on its sidewall. Jaw inserts engage the cam surfaces, such that rotation of the head causes the jaw inserts to slide along the cam surfaces to grip the bore of the workpiece. A retaining band extends around the jaw inserts to retain the jaw inserts on the shank and maintain a desired spacing between the jaw inserts.

Abstract: A releasable honda for lariat ropes has a heel with a throat through which the rope passes, with a tapered throat end forming a cavity for containing a knot in the rope; teeth and/or ridged projections inside the throat retain the rope in position. An axis of the throat is at an angle to a centerline through the heel. Resilient arms extend from the heel at angle to the centerline axis of the heel, and curve toward each other so that the distal ends of the arms almost meet, defining a slit between the arms. Tapered surfaces on the end of each resilient arm cooperate to form a shallow V-shaped indentation on an inner surface of the eye to guide rope into the slit so that a strong pull will force the rope through the slit, releasing the loop; a similar indentation on the outer perimeter of the eye facilitates slipping the rope back into the eye to reform a lasso.

Abstract: A device for gripping a stud to unscrew the stud includes a tubular housing. The housing has an axial bore with a plurality of cam surfaces formed in the bore. A cage is carried in the bore. The cage has a number of windows, each located adjacent one of the cam surfaces. A jaw is carried in each window of the cage. Each jaw has an outer side that mates with one of the cam surfaces and an inner side containing teeth for gripping the stud. The cam surfaces will move each jaw radially between inner and outer position when the housing rotates relative to the cage. A spring urges the jaws to the outer position.

Abstract: A double ended socket has a tapered spline bore in each end thereof. A square hole at a midpoint internal flange provides means for attaching the socket to an impact wrench for removing a thread protector from a pin of a sucker rod. A gripping socket has three floating jaws within a housing to engage coupling of a sucker rod. With an impact wrench, the gripping socket readily removes a coupling from a sucker rod pin. The two tools are used to inspect, clean, and lubricate sucker rods, and to maintain the lubricated pins clean until the rods are run in a well.
