DEFINITION

Classification: 242/413.8

Yieldable drive (e.g., clutch or slip coupling):

(under subclass 413.7) Subject matter wherein the mechanical motion transfer mechanism includes means to either (a) effectively separate (clutch), or (b) alter torque transfer ability (coupling), of elements of the motion transfer mechanism, which means is under the control of the tension regulating system.
