Abstract: A gear system for mechanically transforming motion on an infinitely variable basis as desired, having a unique arrangement of gear elements and clutches between the input and output shafts (1 and 6). A first set of gears (2) divides the motion put into the system through the input shaft (1). A controller (7) sets the phase shift in the division of motion from the first set of gears (2). Sets of non-circular gears (3) connecting the intermediate shafts (9) to "on/off" clutches (4) transform the motion output from the first set of gears (2). Finally, the resulting motion from the clutches is transferred to an output shaft (6) through a third set of gears in a summing device (5). Shaft (6) is connected to a load (not shown).

Abstract: Spring retainer plates for a slip limiting differential are disclosed. Each retainer plate is paired with a similar retainer plate and is adapted to exert a preload on the side gear clutching mechanism of the differential by coil springs interposed between the plates. Each retainer plate has a transverse wall which is generally parallel to the axis of the pinion shaft and has parallel side walls. Each parallel side wall has a generally circular aperture through which the pinion shaft passes. By providing a complete circle of metal around the pinion shaft, plate deformation or breakage is minimized.
