Abstract
A device and method for shifting the operating speed of a machine while under load. The machine includes a casing, an input and output shaft. The device includes a clutch mechanism, a primary carrier, a cluster gear, a ring gear, a first and second gear. The clutch mechanism is operably associated with the input shaft. The primary carrier is operably coupled to rotate the output shaft. The cluster gear is rotatably coupled to the primary carrier. The first gear is rotatably mounted within the casing and second gear is rotatably mounted on the first gear. The first and second gear are in mesh with the cluster gear. The cluster gear is adapted to rotate around the first and second gears on primary carrier when one of the first gear and the second gear is engaged thereby rotating the output shaft at the operating speed corresponding to the engaged gear.
