Abstract: A lightweight, adjustable wrench comprising of a moveable jaw with a reach that is shortened or lengthened with a strap or a cable. The loose end of the strap or cable is secured to the wrench's shank by a cam lock, or similar locking device. Since the strap or cable is the means for the wrench's jaws adjustment, a quicker and easier fit to the pipe or object to be gripped can be obtained. The wrench is more convenient to adjust, since the means for adjustment are located near the handle of the wrench as opposed to the shank end of present designs. The strap or cable adjustment also allows the wrench's shank and handle to be designed hollow and a larger diameter to reduce weight. The wrench can be made in any proportion for any sized application.

Abstract: A pipe wrench is disclosed, the pipe wrench having a uniquely handy control lever and one-way ratchet for very rapid adjustment of wrench position. The wrench also has a pivoting upper jaw that further aids a user in adjusting and tightening the wrench while using only one hand. The wrench may also be used as a hand tool, for instance for clamping an object or workpiece for performing work on the object.

Abstract: An adjustable self-locking wrench is provided. The wrench includes a handle, a base portion having an elongated groove and a locking chamber, a stationary jaw body, a movable jaw having an extension flange, a spring and a locking member. The locking member is movable between a first position wherein the locking member does not tightly contact the extension flange of the movable jaw and a second position wherein the locking member locks the movable jaw in a selected position relative to the stationary jaw.

Abstract: A crescent wrench including a steel ball mounted in a recessed hole in a movable jaw and forced by a spring into engagement with the periphery of a cylindrical control member, which is turned about an axis in an opening in a handle, which has a front end terminating in a fixed jaw, the cylindrical control member having a longitudinal groove adapted for receiving the steel ball for permitting the movable jaw to be released from the constraint of the cylindrical control member, and two longitudinal finger ribs for turning by hand to let the steel ball be moved into the longitudinal groove of the cylindrical control member, or forced out of the longitudinal groove and into engagement with the periphery of the cylindrical control member.

Abstract: An adjustable sliding jaw wrench is disclosed which has a sliding jaw adjustment mechanism operated by a worm gear rotatably mounted in an opening in the wrench head, the worm gear driving a rack member to which the sliding jaw is attached. The worm gear is substantially shorter than the width of the opening in the wrench head in which it is mounted, and is spring biased into an operating position. A sliding locking member is movable between a locked position which will mechanically maintain the worm gear in its operating position, and an unlocked position in which the worm gear will be permitted to move in a direction opposing the biasing spring.

Abstract: A quick-adjust wrench utilizes a sliding jaw which slides with a casing which straddles the wrench shank and captures therein a pawl which rides in a groove extending longitudinally in the shank. A rocker rocks against the pawl when the wrench jaws try to expand, forcing the pawl into its groove in the wrench shank with great force, securely lodging the jaw with respect to the wrench shank to prevent further expansion. This mechanism provides the wrench with infinite and instant adjustability and a very positive, play-free action.
