DEFINITION

Classification: 192/70.17

(under subclass 70.16) Device wherein said means is recoilably yieldable to a limited extent in the rotation direction, whereby the permitted movement is a limited degree of variation between the rotation of a shaft and the rotation of the member supported thereby.

(1) Note. It is emphasized that the amount of variation of transmitted rotation is extremely small, and that the primary purpose of the resilient connection is to absorb shock inherent in the act of causing a stationary clutch-element to be engaged suddenly by a rotating clutch-element. The resilient connection permits the torque to be applied from the shaft to the clutch-element supported thereby (or from the clutch-element to its supporting shaft) without stressing any of the parts to an excessive degree. The "permitted movement" of the clutch-element is rotation momentarily addition to and/or subtractive from the rotation of its supporting shaft. However, the rotation of the clutch-element quickly matches that of its supporting shaft.
