ABSTRACT:
The large close spring in the operating mechanism of electrical switching apparatus is charged by a charging mechanism which includes a charging cam mounted on a cam shaft and rotated by a ratchet wheel. An elongated handle is mounted for rotation about a pivot axis offset laterally from the cam shaft. A drive link which successively engages the teeth on the ratchet wheel is pivotally connected to the handle at a point closer to the handle pivot axis than the radius of the ratchet wheel to increase the mechanical advantage of the handle. A common spring biases the drive link and a stop dog against the ratchet wheel. A turned pin on the drive link is used to engage the ratchet teeth which have an arcuate profile including a radius at the root configured to be engaged by the turned pin. A similar drive link with a turned pin to engage the ratchet teeth is reciprocated by an electric motor. A handle decoupling cam and a motor decoupling cam lift the respective drive links out of engagement with the ratchet wheel when the close spring becomes fully charged. A lifting pin and/or a lateral projection on the handle drive link disengage the handle from the ratchet wheel as the handle is stowed.
