ABSTRACT:
A spring-operated mechanism for actuating a switch gear, etc. comprises a cam member secured to a crankshaft and adapted to be moved thereby. Cam grooves are formed in the cam member such that the distance from the center of the crankshaft is smallest at the middle portion of the groove and progressively increases towards the extremities of the groove. A rod is provided with a pin at one end adapted to be rolled at each end within the cam grooves, and at the other end the rod is provided with a spring support. A stationary member is provided with guide elements to cause the rod to move linearly, and a spring is disposed between the stationary member and the spring support, whereby the spring is adapted to store compressive energy when the crankshaft is rotated through a predetermined angle by a driving source, and, through a further revolution of the crankshaft, the spring releases the stored energy to accelerate the revolution of the crankshaft.
