DEFINITION

Classification: 254/301

With additional axially shiftable clutch mechanism mechanically linked to, and operationally influenced by, first clutch:

(under subclass 299) Apparatus wherein the interlinked drive trains include an additional clutch mechanism similar to the first and mechanically connected thereto, this connection being constructed in such a manner that when the first clutch mechanism engages its rotating components, the other will either engage or disengage its rotating components.

(1) Note. Although each clutch mechanism is by itself a distinct entity, they may have some parts in common, that is, a part may form one of the rotatable components of a first clutch mechanism at one time, and that part may also form one of the rotatable components of a second clutch mechanism at another time.
