Abstract
A power driven tool for rotating a mechanical element. The tool includes a housing and motor. The motor has an output shaft. The shaft rotates relative to the housing. The tool also includes an impact drive axially fixed within the housing. The impact drive includes a base and an anvil shaft having an anvil. The impact drive includes an annular hammer having opposite impact lands pivotally mounted on the base for movement between three positions, including a forward position in which the hammer is positioned so one impact land engages the anvil, a reverse position in which the hammer is positioned so another of the impact lands engages the anvil, and a disengaged position in which neither of the impact lands engages the anvil. Further, the tool includes a ratchet mechanism. The ratchet mechanism includes an output drive mounted for rotation relative to the housing for rotating a mechanical element.
