ABSTRACT:
An improved shifter mechanism for the transmission of a power tool in which the operating lever can be located to either side of the transmission housing. The operating rod has a flat which operates one end of a pivoted shift member, the other end of which moves a clutch member to engage or disengage a rotation clutch. The shifter provides positive action, a long throw, and permits operation in either direction. The clutch itself includes an improved lubrication feature and improved mounting of the fixed clutch member to the armature shaft.
