Abstract
A circuit breaker operating mechanism is disclosed having the opening spring thereof disposed within the closing spring thereof. The closing spring has one end thereof affixed to the operating mechanism support base while the other end thereof is movable relative to the support base for being charged and discharged. The encircled opening spring has a first end thereof which is affixed relative to the mechanism support frame. The other end of the opening spring is movable. However, the latter movable end is held temporarily fixed relative to the support base during a charging operation for the closing spring so that the opening spring will be charged with the charging of the closing spring. When a circuit breaker opening operation is necessitated, the non-fixed end of the opening spring is released, thus allowing the opening spring to discharge while the closing spring remains charged. Consequently, the charging operations for both the closing spring and the enclosed opening spring are in compression and may be simultaneous.
