Abstract
A drive mechanism for a circuit breaker has a spring which is to be tensioned by means of a shaft. On said spring sits a clamp-roll freewheel as a directional lock, whose outer part is connected via a flexible strip traction member to one or more eccentric members. The clamp rollers can be pressed out of their operating position by means of cage disks, which occurs upon reaching the end position of the spring-tensioning shaft by means of a release lever in connection with toggle levers.
