Abstract
The gear box contains three parallel shafts, two of which are interconnected by a system of locking dogs. The third shaft is set in motion at selected different rates of rotation by either a direct drive gear or by a reduction gear. The direct drive gear and the reduction gear are formed of a single member constituted by a compact casting characterized in that it occupies a minimum of space.

- a unitary gear having a first set of gear teeth of predetermined pitch and pitch diameter, and a second set of teeth axially spaced from the first set by an annular groove and of substantially different pitch and/or pitch diameter;
- a ring gear whose outer teeth permanently engage said first set of gear teeth;
- a differential drive gear whose teeth also permanently engage said first set of gear teeth;
- and
