Abstract
A mechanism is provided for use in conjunction with a time accumulating means adapted to accumulate timer run time on a timer mechanism in response to an outward reciprocation of the slide of a coin-receiving mechanism from a fully inward position. The mechanism is associated with the slide and provides for positively stopping inward movement of a gear rack used to set the timer run time and includes resilient means to take up any deviation in mechanism assembly tolerance thereafter without further inward movement of the gear rack.
