Patent number: 6789451Abstract: 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.Type: GrantFiled: March 12, 2003Date of Patent: September 14, 2004Inventor: Arthur Wu

Patent number: 6568300Abstract: An adjustable wrench has a ratcheting feature by which its movable jaw retracts away from its fixed jaw when the handle is pulled in one direction, enabling the wrench to slip over the facets of a polygon-shaped nut, but which locks the jaws in position when the wrench handle is turned in the opposite direction. A jaw adjustment screw is positioned for rotation in the wrench head and is axially movable with the lower jaw, but only when a support wedge is slidingly retracted out from its normal position supporting the bottom end of the adjustment screw. The tool can have a ruled edge adjacent to the jaw for indicating jaw opening size. Another feature is a slidable fence device on the fixed jaw, to be moved slidably over a face of the nut when the wrench is in place, providing a stop against sliding of the wrench off the nut.Type: GrantFiled: May 23, 2002Date of Patent: May 27, 2003Inventor: Michael Steffe

Patent number: 6145415Abstract: A pair of pliers includes a head and a handle pivotally connected to the head which includes three parts. A movable jaw is movably received between the first part and the third part of the head and a first spring is connected between the movable jaw and the second part. The movable jaw has a toothed portion defined in one of two sides thereof. A pawl member is movably received between the first part and the second part with a second spring connected to the pawl member and the second part. The pawl member is moved along an inclined surface of the second part and has a toothed side which is disengagably matched with the toothed portion of the movable jaw by rotating the handle.Type: GrantFiled: February 12, 1999Date of Patent: November 14, 2000Inventor: Kuo-Chen Liu

Patent number: 4712455Abstract: A sliding jaw pipe wrench has a jaw adjustment mechanism comprising a longitudinally extending series of transverse recesses formed in one surface of a elongate shank on which the movable jaw of the wrench is formed. The shank is received in a retaining pocket in the wrench handle on which the stationary jaw is formed, and the handle includes a transverse locking pin for engagement in, and disengagement from the respective recesses to retain the movable jaw in position when engaged in a recess and allow the shank to be moved to adjust the jaws when disengaged from the recesses. The locking pin is operated by a trigger-like lever pivoted on the handle and connected to a locking pin by an elongate actuating rod. The wrench is provided with a fine adjustment mechanism in the form of a stud threaded transversely through an aperture in the handle so that the inner end of the stud can be tightened against an edge of the shank opposite the recesses.Type: GrantFiled: March 3, 1986Date of Patent: December 15, 1987Inventor: Terrence D.
