Abstract: A viper crescent wrench device for holding a work piece is provided. Upon squeezing a second handle toward a first handle, a first pawl and a second pawl move an adjusting bar toward the first handle thereby moving a second jaw portion toward a first jaw portion. Upon releasing the second handle, the first pawl and the second pawl releasably lock into place and the second handle readjusts relative to the first pawl thereby repositioning to do the same action again when the second handle is squeezed again until the work piece is secured between the first jaw portion and the second jaw portion. Upon rotation of a release mechanism, toothed notches are rotated out of contact with the first pawl and the second pawl such that the second jaw portion moves away from the first jaw portion under bias of a first spring thereby releasing the work piece.

Abstract: An adjustable wrench has a handle having a fixed jaw, a movable jaw, an adjusting worm and an adjusting device. The adjusting worm is received in an opening of the handle and engages with the movable jaw to drive the movable jaw to move along the guiding slot. The adjusting device has an axle portion received in a through hole of the adjusting worm and a wheel portion positioned beside the adjusting worm. The adjusting device is pivoted on the handle via a shaft to be turned along a rotation axle and the adjusting worm is turned along a rotation axle. The rotation axles of the adjusting device and the adjusting worm deviate from each other whereby the adjusting device is turned to move the adjusting worm toward or away from the movable jaw.

Abstract: A socket wrench driven adjustable jaw crow foot wrench is an assembly of four primary components: a chassis; a carriage; a ratchet; and a pawl. The chassis has a stationary jaw at a first end, a track extending from the first end to a second end of the chassis; and a cavity which opens to the track and opposing sides of the chassis. In a preferred embodiment of the tool, a female receiver for a socket wrench is provided on an end of the tool opposite the track. The carriage bears a jaw designed to mate to the stationary jaw of the chassis. The carriage is provided with a rack. Said carriage is designed to travel in the track provided on the chassis. The ratchet is provided with a female socket wrench receiver, and is located in the cavity provided in the chassis. The ratchet is juxtapositioned to communicate with the rack on the carriage. The pawl is located in the cavity provided in the chassis and juxtapositioned to communicate with the ratchet.

Abstract: An adjustable open-end wrench is formed with a C-shaped base jaw member having an upper base grip-forming portion and a lower tongue-forming portion which is pivotally connected to an elongated handle. An L-shaped, sliding jaw member has a horizontal leg which is slidably guided between the upper and lower portions of the base jaw member. The sliding jaw member has an upright leg forming a movable grip portion opposing the base grip portion. Corresponding, normally interengaging, tooth-like locking formations are formed on the upper end of the handle and the lower edge of the movable jaw member horizontal leg for normally locking the jaw members relative to each other. The handle may be pivoted to temporarily release the interengaging locking formations so that the movable jaw member may be slidably moved relative to the base jaw member for adjusting the distance between the grip portions to accommodate to different size bolts and nuts.

Abstract: An adjustable open-end wrench having an elongated body member, one end of which is a handle, and the other end of which includes a fixed jaw portion and jaw-base portion having a reentrant groove therein with a movable jaw member slidably mounted in the reentrant groove and a rack portion on the bottom of the movable jaw member for interaction with a second rack member located in another chamber in the body member located just below the reentrant groove, that chamber also housing the interior end of a button member which extends to the exterior edge of the wrench body member, and a lever member and biasing means for biasing the button member outwardly while biasing the rack members into engagement with each other. By simply pushing the exposed portion of the button member, the movable jaw is released for slidable adjustment of the width of the open-end wrench opening.

Abstract: A wrench having a stationary jaw mounted on a handle, a rigid member releasably attached to the handle and an adjustable jaw disposed on the rigid member, the rigid member retaining the adjustable jaw in an interengageable position with the handle when the rigid member is locked with the handle by a latch.

Abstract: A quickly adjustable ratchet wrench is essentially a crescent wrench modified by eliminating the adjusting screw and substituting a locking member and a lever to engage and disengage the locking member with the rack on the movable wrench jaw. A tension spring lightly biases the movable jaw toward closed position. With the locking member disengaged from the rack, the movable jaw may be manually opened, and when the movable jaw is released the light spring bias closes the jaws on a bolt head. When the wrench jaws are engaged with a bolt head, rotation of the lever arm in one direction engages the locking member with the rack to turn the bolt, while rotation of the lever arm in the other direction disengages the locking member and permits the jaws to open against the light spring bias and slip over the angles of the bolt head; thus eliminating the need to remove and replace the wrench on the bolt head. The lever is pivoted substantially on the line of movement of the movable jaw.

When the wrench jaws are engaged with a bolt head, rotation of the lever arm against a rearward extension that replaces the wrench handle engages the locking member with the rack to turn the bolt, while rotation of the lever arm away from the extension disengages the locking member and permits the jaws to open against the light spring bias and slip over the angles of the bolt head; thus eliminating the need to remove and replace the wrench on the bolt head.
