DEFINITION

Classification: 192/48.3

(under subclass 48.1) Device wherein one of the associated clutch-assemblages is different in its principle of operation from another.

(1) Note. Examples of arrangements wherein the principle of

operation is "different" include: Arrangements wherein one clutch-assemblage is actuated by fluid pressure whereas another clutch-assemblage is actuated by mechanical linkage; arrangements wherein one clutch-assemblage uses clutch-elements that engage positively, as by splines, intermeshing teeth or ratchet-and-pawl elements, whereas another clutch-assemblage uses clutch-elements that engage frictionally, as by surface-to-surface contact; and arrangements wherein one clutch-assemblage is intended to function in only one direction of rotation whereas another clutch-assemblage is intended to transmit all torque applied thereto in either direction of rotation. Minor differences in shape or size between the elements of clutch-assemblages, not involving differences in operation, are not justification for placement into this and indented subclasses. For example, an arrangement of clutch-assemblages wherein one has tapered clutch-elements and another has disc clutch-elements or an arrangement of clutch-assemblages wherein one uses rollers and another uses balls, are not properly considered to be "diverse", but will be classified in subclasses 48.11+ according to their plural characteristics.
