ABSTRACT:
An improved reversible transmission employing a planetary gear train between an input and output shaft so that when the carrier of the planetary gear train is free to rotate and the carrier is coupled to the output shaft the input and output shafts rotate in the same direction and when the carrier is held stationary the output shaft rotates in the opposite direction to the input shaft. The carrier is selectively coupled to the output shaft through a two stage coupling the first stage of which incorporates a friction drive device and is initially engaged and held so engaged while the second stage is operated to provide a direct mechanical coupling between the carrier and the output shaft.
