DEFINITION

Classification: 192/87.11

(under subclass 87.1) Device wherein the functioning of one clutch-actuator is unrelated to the functioning of another clutch-actuator.

(1) Note. This (or an indented) subclass is the locus, for example, of a claim directed to the combination of three clutches, two of which are alternatively engaged (i.e., one is engaged while the other is disengaged), and the third of which may be engaged regardless of the condition of either of the first two clutches. A claim wherein a plurality of clutches must all be engaged or disengaged simultaneously is not considered as proper for this subclass but will be found in subclass 87.1 above.
