Abstract

An improved mechanical counter including digit wheel means stepping pinion means which are movable between first and second positions, engaging and disengaging, respectively, the digit wheel means, and a resetting mechanism including a resetting rake, which is pivotally movable between an initial position in which rake is clear of the digit wheel means, and an actuated position. Also included in the resetting mechanism are a slider member connected to a pivoted member, which at its end opposite to the slider member is pivoted on a stationary pivot pin. Remote from its pivot pin, the pivoted member has a U-shaped coupling recess for actuating the resetting rake, and an S-shaped cam slot for disengaging the pinion means from, or re-engaging the same with, the digit wheel means, respectively. The resetting rake carries a coupling pin that is engaged by a respective edge of the pivoted member at the U-shaped coupling recess thereof. The pivoted member is adapted to cooperate with the coupling pin only when the pinion means are in their first and second positions. Resilient means are also provided to yieldably hold the rake in its initial and actuated positions.
