Open the CIPO recordAbstract From the Canadian patent
For sequentially setting independently-rotatable spur gears which are coupled to print wheels in a postage meter, a yoke carrying a selectively-driven master gear is shifted along an axis parallel to the common axis of the adjacent gears. A rack attached to the yoke is driven by a pinion gear on a stepping motor shaft. The yoke is spring-biased to a disabled position in which the spur gears are mechanically locked into position by tooth troughs on the yoke surface. A print interlock mechanism permits printing only when the yoke is held in an enabled position against the force of the biasing spring.
