ABSTRACT:
A reversible ratchet wrench has a wrench handle with a circular ratchet head having a cylindrical array of ratchet teeth and receiving coaxially rotatably therein a drive body. A pawl is carried by the drive body for movement between forward and reverse conditions of engagement with the ratchet teeth, being retained in each of these positions by an over-center spring engageable with a pin on a reversing lever disposed coaxially with the drive body and retained thereon by a bushing and a screw for rotation relative to the drive body and the ratchet head for shifting the pawl between its forward and reverse conditions. Indicia on the bushing and the reversing lever cooperate to indicate the condition of the pawl.
