ABSTRACT:
The normally engaged spring clutch assembly has a helical spring in interference fit with driving and driven clutch drums to transmit rotation from one clutch drum to the other. A control sleeve surrounds and is in close spaced relation to the spring. Each of the opposite end portions of the spring are engageable with the sleeve so that, in the engaged condition of operation, the sleeve rotates with the spring and, in the disengaged condition of operation when rotation of the control sleeve is arrested, the spring is caused to release its grip on a clutch drum. The disengagement of the spring clutch assembly is achieved whichever clutch drum is the driving clutch drum.
In another embodiment, the spring is so formed that, upon disengagement by arresting rotation of the control sleeve, a portion of the spring engages the control sleeve to stop the overrun of the driven clutch drum.
