DEFINITION

Classification: 192/70.28

(under subclass 70.27) Device wherein the elastic bodies tend to move the members apart from one another.

(1) Note. Examples of devices in this subclass (70.28) include: a device wherein a spring is used alternatively to engage or to disengage the clutch-elements, and a device wherein a spring is stressed (as by actuating a lever) only when the clutch-elements are to be disengaged. The necessary requirement is not the means for urging the clutch-elements into engagement (such means will be found elsewhere in this class (192) but rather than a spring is used to disengage the clutch-elements.
