ABSTRACT:
An operator is provided that includes a common drive for charging an operating mechanism and for driving a functional accessory device in predetermined coordinated relationship. The common drive in a specific embodiment is provided as a drive shaft at the output of a drive train. The operating mechanism is charged as the drive shaft is rotated from a first to a second predetermined position. The functional accessory device is also driven via the drive shaft; the functional accessory device being operated from a first predetermined operational state to a second predetermined operational state in response to the rotation of the drive shaft between the predetermined positions. When desired, the functional accessory device is operated from the second predetermined operational state to the first predetermined operational state by subsequent rotation of the drive shaft to the first predetermined position. The operating mechanism is controlled thereafter to close the contacts of one or more interrupting units. The operating mechanism is capable of immediately opening the contacts of the one or more interrupting units after closing. After opening of the contacts of the interrupting unit and when desired, the drive shaft is rotated from the first to the second predetermined position to again charge the operating mechanism and drive the functional accessory device to the second predetermined operational state. In one embodiment of the operator, a charging cam is carried by the drive shaft for charging the operating mechanism. The charging cam, in a specific embodiment, includes a predetermined cam surface that cooperates with the operating mechanism to inhibit movement of the drive shaft and thus inhibits operation of the functional accessory device when the motor of the drive train is deenergized. In one arrangement, the functional accessory device is one or more disconnects with a disconnect being connected in series circuit with each interrupting unit.
