Actuator for transfer circuit breaker switch

Claim 1

In a circuit breaker configuration of the type in which individual switch components are aligned adjacent one another and whose condition of operation is determined by the respective positionings of the control arms thereof, in which a first plurality of such switch components are interconnected together for a simultaneous tandem operation of a first type, in which a second plurality of such switch components are interconnected together for a simultaneous tandem operation of a second, different type, and in which said first and second pluralities of switch components include first and second control arms oriented so that said arms are positioned away from each other when said switch components are on and towards each other when said switch components are off, apparatus comprising: rod means, coupled between the control arms of adjacent switch components in each of said first and second switch component pluralities, and linking said arms of each plurality together; an interlock; with a first end of said interlock being apertured to receive said rod means of one of said switch component pluralities, and to transfer to said rod means substantially any lineal movement imparted to said interlock; with an opposite end of said interlock being slotted to receive said rod means of the other of said switch component pluralities, in affording a degree of lineal movement therein; with the length of said slot being slightly less than the lineal distance between the positionings of said first and second control arms when in "ON" and "OFF" conditions, respectively; and with one end of said slot being co-linear with the position of the switch control arm when in either of its states of on-off operation.
