A meter construction wherein purchased time is obtained through engagement of pawl means with a winding means attached to a timing mechanism, the pawl means being moved into engaging position by a coin employed for purchasing time. The improvement involves the use of a pair of rotatable members operatively connected to the winding means. A first rotatable member is directly tied to the winding means whereby driving engagement of the pawl with the first rotatable member will result in the purchase of time. The second rotatable member is maintained in spaced relationship with respect to the first rotatable member, and the subsequent insertion of a coin results in engagement of the second rotatable member, and movement of this member relative to the first rotatable member. Driving engagement with the first rotatable member follows this initial movement and the purchase of time only begins at this point. This results in a lower ratio of purchased time to coin value. Additional delay of movement of the first rotatable member and operation of the associated time mechanism is accomplished through the use of a blocking member which holds the pawl out of an engaging position when a coin is inserted after a certain amount of purchased time is already on the meter.
