Abstract
The headed end of a wrench body of elongated rectangular form includes a first stationary jaw defining a first gripping surface. A slide mount foot projects from the body opposite the stationary jaw, and is spaced therefrom. It includes a flat bearing surface. A slidable jaw shoe mounts on the foot, and is slidable towards and away from the wrench body headed end. The shoe has a bite portion forming a second gripping surface which extends parallel to the stationary jaw first gripping surface and faces the same. A straight wire spring has one end fixed within a V-shaped groove which diverges from the stationary jaw within the side of the wrench body towards the foot with the straight wire spring having a free end fitting with an oblique slot within a sliding jaw shoe, permitting the slidable jaw shoe to move in opposition to the bias to ratchet the wrench about a nut or bolt head captured between the first and second gripping surfaces when rotating the wrench body in a first direction. During rotation of the wrench body in an opposite direction, the first and second gripping surfaces grip opposite parallel flats on the nut or bolt head to force the nut or bolt head to rotate with the wrench body.
