CIRCUIT BREAKER CLOSING MECHANISM ABSTRACT OF THE DISCLOSURE A circuit breaker the moving contacts of which are closed by a charged spring or plurality of springs in which the circuit breaker is of minimum size for any given application and maximum simplicity in manufacture. The circuit breaker closing system is a cam closed system in which the closing cam acts also as a prop latch for supporting the spring operating mechanism in charged position. The cam follower path is determined by three cam surfaces between which the closing forces are transmitted through free floating rollers; this obviates the need for toggle links for the transmission of forces or the guiding of the cam follower rollers. This arrangement, by permitting the distribution of the variable mechanical advantage of a cam slope among three members, instead of building it into just one member allows the use of a smaller diameter primary closing cam; it also permits an application of closing forces appropriately tailored to the requirements of each circuit breaker. This application is related to and filed simulta- neously with Canadian applications Serial Numbers 285,925 and 285,978 in the name of George A. Wilson and assigned to the assignee of the present case.
