(under subclass 3.21) Device including a rotated input shaft that drives the combination (i.e., the vortex-flow drive plus the clutch), and a rotatable output shaft which may be driven by said combination in a first direction of rotation, and provided with means to change the direction of rotation of said output shaft while the input shaft continues to rotate in its original direction.
(1) Note. The shafts referred to in the definition above are not necessarily those referred to in the definition of "Vortex-Flow Drive", as found in (1) Note to the definition
of subclass 3.21. If, in a particular disclosure, a shaft serves both as an "input" or "output" shaft as defined in this subclass (3.22) and as a shaft defined in subclass 3.21, such occurrence is coincident rather than significant.
(2) Note. The "means" referred to above may comprise a second clutch, or a brake, or structure to reverse the flow of fluid within the vortex-flow drive.
