[Also in Division H1] A spring power-storing mechanism which controls the operation of a circuit breaker (not shown) comprises a spring 30 charged by rotation of a shaft 14 through the intermediary of a crank 16 and a toggle linkage 20, 24, movement of which is controlled by a guide means 40. The shaft 14 is driven intermittently or continuously in the direction A by, e.g. an electric motor. As the crank 16 rotates the spring 30 is charged by the moving apart of points 22 and 28, and the lever 20 moves up until a roller 36 abuts the cam 40, causing the toggle linkage to collapse. The energy stored in the spring rotates the shaft 14 and causes a cam 42 to close the circuit breaker contacts. |
