Abstract
A telephone-type ringer assembly with an improved volume control operable from the exterior of the closed housing in which the ringer is contained. The volume control comprises an eccentric control wheel for one gong to settably vary the distance from the striker to one gong. The setting of the gong is controlled by a detent pivoting the control wheel with the detent position being controlled by a rod having an eccentric connection to a setting control on the housing exterior or directly through a suitable slot in the base which does not require the rod and attached lever. The ringer is designed to be mounted to the base directly on bosses molded onto the ringer frame. This mounting alternatively allows a detent spring extension to project through the bottom of the base for direct control, eliminating the need for a linkage. Pivotal movement of the control advances or retracts the rod to pivot the detent accordingly, the detent mating with plural position stops in the assembly within the ambit of lateral extent travel stops.
