Abstract
A dual-pawl ratchet wrench mechanism is disclosed having a stop mechanism for limiting over-travel of a reversing lever for selecting drive directions. In one form, the wrench mechanism includes a ball and spring assembly that cooperate with recesses to define proper positions for the reversing lever, and one or more ramps are provided between the recesses to promote tactile feel and to promote the reversing lever being rotated to a proper position. In some forms, the stop mechanism is formed on a stationary portion, such as a spacer or the wrench body, and a portion of the reversing lever. The design simplifies manufacturing, such as by simplifying assembly and minimizing the need for securements. Additionally, the reversing lever is assembled with the mechanism in a manner to improve sealing.
