Abstract
An apparatus is provided that allows a working element to undergo either rotary or reciprocation motion in a transmission system that is very compact in terms of the amount of space it requires to convert the rotary output of the motor into either rotary or reciprocating output of an output shaft operably connected to the working element. The transmission includes input and output members between which a clutch and cam mechanism are disposed for providing a rotary/reciprocating transmission system with a compact design. When the clutch is disengaged, the cam mechanism is operable to provide the output member and thus the output shaft connected thereto with reciprocating motion. Preferably, the output member is cylindrical with the input member, clutch and cam mechanism all disposed therein to provide the rotary/reciprocating tool with a so-called “barrel cam” transmission that is small to provide significant space saving in the tool housing.
