Abstract
Abstract A transmission comprising an epicyclic gear train with a belt pulley drive which provides a speed reduction during reverse rotation, and control mechanism which operates in common with a brake jaw, which retards the rotary movement of the planetary gear carrier, and a belt engaging member which directs the motion of the epicyclic gear train.
