ABSTRACT:
A number wheel assembly for a counter mechanism has a plurality of hubs with an eccentrically shaped aperture for slideable assembly and orientation on a shaft and eccentric lobe. Each hub having a recess and a pinion spindle in the recess for receiving an internal pinion gear having narrow teeth alternated with wider teeth that extend outside the hub. The number wheels, which represent successive orders of magnitude, are slipped over the hubs. Each number wheel has a single tooth that engages one of the wider teeth of the pinion gear driving the next higher order number wheel once for each revolution of the number wheel. This moves the pinion which, in turn, moves the next higher order number wheel. The gear ratio is 1:10 for a decimal counter. The lowest order number wheel is a drive wheel which includes means operable by a drive mechanism for advancement in increments of 1/10 revolution for each cycle of operation of the drive mechanism.
