More Information
Summary:A meter apparatus wherein time is purchased upon deposit of a coin or the like for setting of a clock mechanism. A parking meter may be involved, and a rotatable handle is provided for operating a drive shaft connected between the clock mechanism and handle. A clutch is interposed between the handle and drive shaft with the clutch including a pin or other releasable element engaging both the shaft and handle. A spring force is applied to the pin so that normal rotation of the handle will operate the drive shaft. Excessive force will release the pin in opposition to the spring so that damage will not occur even upon continued rotation of the handle. The pin and handle are ordinarily reset in a proper starting position so that the next operation of the meter will proceed in correct fashion.
