Abstract: A slogging wrench (10) comprising: a ring socket (36) for receiving a nut or a bolt head (NBH, NBH?); an elongate body (20) for receiving blows from a mass to transmit torque to the ring socket; and a tool-free locking mechanism (22,24,26,26?,28,30) for retaining a nut or a bolt head in the ring socket. The locking mechanism comprises a slider (22) operable to engage a nut or a bolt head in the ring socket; a channel (24) for guiding movement of the slider towards and away from the ring socket; and an actuator (30,74) manually operable to move the slider with respect to the ring socket. The channel (24) opens into the ring socket (36) via an internal periphery (40) of the ring socket. The locking mechanism comprises a resilient member (34) biasing the slider (22) towards a nut or a bolt head (NBH, NBH?) in the ring socket (36).

Abstract: A pre-load monitor is arranged for use between a washer face of a fastener and a bearing surface of a fixture arranged to receive a portion of a shank of the fastener. The pre-load monitor, which can be in the form of a washer, includes a piezoelectric generator which generates the electrical power to measure, monitor and report the pre-load. The resulting electrical power produced is proportional to the pre-load and can be stored to provide the energy required to function electrical, electronic and communication circuits included in the washer. Alternatively, the pre-load monitor can be a half- or split ring (or a C-ring) constructed similarly to that of the washer, or the ring can be a two-piece gasket construction that includes an array of the washers.

Abstract: An adjustable wrench comprises a handle. At least one end of the handle is provided with a straight claw (2) and an oblique claw (1), which form a wrench jaw by a certain angle. The straight claw is provided with an adjusting slider (4) capable of moving along the length direction of the straight claw and the adjusting slider comprises an oblique face (41) in action with a nut, and the oblique face is parallel to the inner surface (11) of the oblique claw forming the wrench jaw. The adjustable wrench retains advantages of a solid wrench which is precise in the opening size and not easy to slip, and solves the problem that the opening width of the existing solid wrench cannot be adjusted. Meanwhile, the adjustable wrench completely retains the advantage of the existing adjustable wrench which is continuously adjustable in the opening width, and solves the problems that since a shifting wheel and a rack are easy to abrade, slipping is easy to occur or nuts can be damaged.

Abstract: The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers.

Abstract: A slide switch adjustable wrench uses a laminated steel construction method that includes a stepped surface to form a guide for the worm gear driven moving jaw. A molded or similarly formed body is sandwiched between the steel housing sides to form a sturdy structure. The body provides cavities, bearings and other features to support and guide moving parts within. A rack and pinion drive system uses simple molded gears to amplify about 2 inches of switch travel into about 6 turns of the worm gear. An overmolded rubber edge grip bonds to the body to create a recess in the body; this recess seamlessly fits the steel sides to form a smooth continuously contoured grip surface.

Abstract: An adjustable wrench comprising a handle, a stationary outer jaw member integrally formed with the handle and having at least one outer face and a support surface for a moveable jaw, and a moveable jaw member riding on the support surface and continuously supported thereby during its entire range of movement, the moveable jaw member having an inner face parallel to the stationary outer face whereby the turning of a nut placed between the stationary outer face and the moveable inner face creates a force a part of which is applied to the moveable jaw member in a direction perpendicular to the direction of travel of the moveable jaw member thereby forcing the moveable jaw member against the support surface.

Abstract: The present invention provides a wrench having a removable key and key adjustment assembly. The key itself includes a nut receiving face having chamfered upper and lower edge regions to one side of the key and a notch intermediate the other side of the key. The key is removably secured to a threaded stem fitted within a longitudinal opening through the wrench head with a screw securing the stem to the key. The screw releases the stem and the key from another with the stem being then removable through the axial opening and the key itself being removable from the wrench head by engaging the notch with the edge of the cavity and clearing the chamfered edges past the cavity wall suh that the key pulls directly out through the cavity.

Abstract: An adjustable wrench having a fixed jaw and a spring biased movable jaw. A coil spring acts on an end of a worm gear opposite the fixed jaw, which, in turn, acts on a rack of teeth provided on a portion of the movable jaw to force the movable jaw towards the fixed jaw. The worm gear is rotated to advance the movable jaw against an object which is to be gripped. Upon contact of both the movable jaw and the fixed jaw with the object, the worm gear is rotated further to compress the coil spring. The force of the coil spring against the worm gear diminishes looseness between the worm gear and the movable jaw, and compression of the coil spring further diminishes any such looseness and enhances holding power of the wrench about the object.

Abstract: The present invention relates to a movable wrench equipped with movable claw which is driven and rotated by adjusting rod, wherein front and rear ends of rotary shaft respectively couples with I type Fan-shaped gear and adjusting rod by two pins, and concave ring of I type fan-shaped gear is propped by screw, and when adjusting rod is rotating, rotation of adjusting rod moves through rotary shaft and I type fan-shaped gear to fan-shaped gear at another end of adjusting rod and drives fan-shaped gear to slid the movable claw forward and backward. Further design of the present invention is to dig a longitudinal groove for sliding a driving pin at the bottom end of rotary shaft, and in the inner hole of adjusting rod, there designed inner thread for screwing with external thread of handle, owing to the above-mentioned design adjusting rod can adjust movable claw, to increase or decrease length of handle, and increase arm of force to save labor and let movable claw not slid when workpiece is wrenched.
