Abstract
An interface for facilitating user resetting of a mechanical registering mechanism interconnects a decrementing register with a remote meter resetting lock. The user is provided with the current lock combination after debiting the user's account for the amount to be incremented into the register. With the lock released, a resetting knob is rotatable to drive a gear train which engages a pinion on a register numeral wheel. Rotation of the knob initially releases numeral wheel lockout combs to permit the gear train to advance the numeral wheel. A separate gear train is provided for each register wheel to be reset with a Geneva transfer tooth in the driven gear train indexing an adjacent gear train which drives a higher order numeral wheel. The interface additionally provides for conventional meter resetting by authorized personnel through the implementation of manually actuatable thumb wheels for optionally driving the gear trains.
