ABSTRACT:
A turns-counting dial for multi-turn potentiometers and the like, and having an intermittent-motion mechanism connecting a shaft-mounted control knob to a turns-counting ring. An interrupted-tooth gear coupled to the turns-counting ring is locked against rotation except during turns-counting movement by a flange on a coupling ring positioned radially inwardly of the gear within the dial. This arrangement provides secure locking of the turns-counting dial, provides flexibility in the number of turns to be counted, enables use of relatively low-tolerance parts, and strengthens the intermittent-motion mechanism against breakage or distortion if torque is applied to the turns-counting ring.
