  • Patent number: 3964590
    Abstract: A meter construction such as a parking meter wherein time is purchased upon insertion of coins into the meter. A time indicator means is movable over a dial face for displaying the amount of time purchased. Cam follower means are connected to the indicator means so that the indicator means is held in displaying position after purchase of time when the follower is held in engagement with a cam connected to the clock mechanism. Once time has been purchased, and the follower is not manually held in engagement with the cam, the time indicator disappears from view. Manually operated means are provided for moving the indicator and associated cam follower so that if the previous purchaser or a new purchaser arrives at the meter, it will be possible for either one to determine the amount of previously purchased time remaining on the meter.
