Abstract: An open end ratchet wrench includes a housing defining a handle and a head surrounding an open mouth and a central axis of rotation. A carriage is rotatable about the central rotational axis and carries a moving jaw member for engaging a multi-sided element. A squeeze lever is operable to rotate the carriage and the moving jaw member continuously about the central rotational axis, selectively in either a clockwise or counterclockwise direction. An engagement assembly operates the moving jaw member between an operable position in engagement with the multi-sided element and a retracted release position, wherein the moving jaw member backs away from the central rotational axis to release from operative engagement with the multi-sided element. A switch operated carriage return assembly spins the carriage and moving jaw member to a start position to thereby allow removal of the wrench from the work piece.

Abstract: An open-end ratchet wrench includes a housing defining a handle and a head with an open mouth for receiving first and second elements of a work piece therein. A fixed jaw member on the wrench engages the first element and a moving jaw member engages the second element of the work piece. A squeeze lever is operable to rotate the moving jaw member about a center axis of rotation selectively in either a clockwise or counterclockwise movement, to thereby tighten or loosen the second element relative to the first element. An engagement assembly operates the moving jaw member between an operable position in engagement with the work piece and a retracted position, wherein the jaw member moves away from the center axis of rotation to back off and release from operative engagement with the second element, thereby allowing removal of the wrench from the work piece.
