Abstract

A digital clock having backlash-free gearing between a step motor and digit wheels that indicate time. The gearing includes an input pinion connected to the step motor, intermediate gearing driven by the pinion and an output ring gear driven by the intermediate gearing and connected to drive a seconds digit wheel of the clock mechanism. A pivotal bracket rotatably carries the intermediate gearing and is biased in one direction by a spring so that the intermediate gearing is urged into backlash-free engagement with both the input pinion and the output ring gear. The bracket tilts as well as pivots to permit the intermediate gearing to properly mesh with both the input pinion and the output ring gear.
