The slow-speed pulley 5 is coupled to the fast-speed pulley through an epicyclic train comprising planet pinions 33, 34, sun gear 38 secured to pulley 5 and ring gear 37 secured to pulley 4. The pinions 33, 34 are keyed together and are mounted on a plate 35 secured to the shaft 1 so that when the belt shipping mechanism transposes the belt on to the slow pulley 5 the motion of the slow pulley is transmitted through the epicyclic train to drive the fast pulley at a slower speed and its motion is transmitted through the usual train of gears to the shaft 1 to drive it at a slower speed. The loose pulley 6 is freely rotatable about a hub portion 5a formed on the slow pulley.
