  • Variable speed ratchet wrench and method of use
    Patent number: 6681660
    Abstract: A variable speed ratchet wrench comprising a main handle portion with an opening for receiving a planetary gear mechanism, a planetary gear mechanism with a locking device attached to an output shaft for driving wrench fittings, and a planetary gear housing cover. The planetary gear housing cover comprises an attached secondary handle that allows the planetary gears to revolve relative to the sun gear in a non-locked position and prevents the planetary gears from revolving about the sun gear when locked in a locked position, thereby providing a geared speed increase in the driven speed of the output shaft. The planetary gear mechanism includes a sun gear, a first and second planetary gear, and an inner ring gear for driving the output shaft.
