Abstract: An improved set of adjustable locking pliers having two pivotally mounted jaws. A lock lever is pivotally mounted to one handle member and slidably retained in the longitudinal grooved portion of the opposite handle, and an adjustment screw threaded longitudinally into the grooved handle member bears upon the sliding end of the lever. Handle members are pivotally connected to retaining plates, said plates having a pin projecting between them with the jaws pivotally mounted and laterally disposed thereon. The gripping surfaces of the jaws interlock above the pin and meet flush in the locked position. The handle member having the adjustment screw has a curved end which spreads the bottom of the jaws apart in the locked position, thereby forcing the gripping surfaces together.

Abstract: An open-ended adjustable ratchet wrench having a first jaw with a fastener contact surface thereon is slideably connected to a second jaw with a second fastener contact surface thereon for grasping a nut or bolt. A link member is pivotally attached to the first jaw along a first axis and an elongated handle is pivotally attached at one end thereof to the link member along a second axis, the second axis being parallel to the first axis. A rack having a plurality of teeth thereon is disposed on the second jaw for movement with the second jaw and is in engagement with a pinon gear rotatably attached to the link member about the first axis.
