Abstract: A method and device is disclosed for clamping an object with quick adjusting pliers. A top jaw has a bottom handle, a slot, and a series of ridges located around the slot. A pin extends through the slot and includes an engagement element. A bottom jaw has a top handle and another opening for receiving the pin. The engagement element engages at least one of the series of ridges in a first position, wherein the top jaw and bottom jaw pivot about a first axis that extends through a longitudinal axis of the pin, and wherein the engagement element is moveable along the first axis from the first position to a second position wherein the engagement element does not engage any of the series of ridges.

Abstract: A large capacity locking pliers includes a body, a fixed jaw, a movable jaw, and an over-center toggle linkage secured between the movable jaw and the body to lock the movable jaw in position with respect to the fixed jaw. The jaws define respective working surfaces, and each of the working surfaces defines an end portion, an intermediate portion, and a concave inner portion. The concave inner portion of the fixed jaw extends over an arc .alpha. of at least 45.degree. and the concave inner portion of the movable jaw extends over an arc .beta. of at least 80.degree.. These concave inner portions are concentric when the movable jaws move to a selected open position to grip a large cylindrical workpiece. The fixed and movable jaws are asymmetrical in order to facilitate fabrication and finishing of the completed pliers.
