ABSTRACT:
A counter employs a barrel for rotatably mounting high order counter wheels and a shaft integrally extending from the barrel for mounting the lowest order counter wheel. The barrel forms a groove in which the transfer pinion assembly is located. The walls of the groove are engageable by the pinion assembly to limit skewing of the pinion assembly components. The transfer pinions are configured to prevent axial jamming displacement against the counter wheels. The lowest order wheel is snapped onto the shaft and secured in position by means of a semi-flexible mounting hub and cooperative shaft detents. The counter forms an efficient internal light path for illumination of the counter.
