A manually actuated self-collecting parking meter includes a single lockable coin insertion device for receiving a range of available coin diameters. A coin checking device is arranged to receive one coin at a time from the insertion device and is placed in operation by turning a rotary locking handle. A parking time period display mechanism is arranged to be set based on the coin inserted into the checking device when the handle is rotated. The rotary locking handle can be rotated in either direction up to a stop for loading a force accumulator which automatically drives an operating mechanism for effecting the operation of the coin checking device and the setting of the display mechanism. For proper phase control of the operating mechanism, a closing segment and an operating segment are provided which uncouple the operating mechanism when the rotary handle is completely rotated so that the automatic operation is carried out.

Manually actuated, self-collecting parking meter

A device for testing the magnetic properties of coins in coin operated apparatus such as parking meters, used in conjunction with a coin diameter testing device. The device includes a double arm rocker lever provided on a side wall of a coin guiding duct. A first arm of the rocker lever is equipped with a permanent magnet and the latter extends through an opening of the side wall into the range of a coin which has been inserted into the coin guiding duct and which temporarily rests on a coil support. A second arm of the rocker lever includes a locking bracket which can be controlled so as to be in and out of engagement with a testing segment required for the test for determining the diameter of coins.

Device for testing properties of coins

A coin activated timer mechanism particularly useful as a parking meter including a sensing device for sensing the value of coins received in a coin receiving device in order to actuate through a transmission lever a time indicator mechanism which includes a timer disc rotatable in individual angular steps for providing an indication of a time period dependent upon the value of the coins received. A clockwork mechanism returns the time indicator mechanism to a position indicating expiration of the time period and a function lever operates to effect actuation of the timer disc through the individual angular steps. The function lever is driven by the transmission lever to a position at which the time indicator mechanism is released with the timer disc being simultaneously guided to a position indicating a determined time allotment.

An arrangement for resetting a coin operated parking meter is disclosed. By the use of a sensor to monitor a parking space, it can be determined when a vehicle leaves the parking space with parking time remaining. A resetting device within the meter clears the meter of remaining parking time. The resetting device includes an electric motor, a cam disk affixed to the motor shaft and a coupling member arranged between the cam disk and time indicating portion of the meter. The coupling member returns an indicator of the time indicating portion to a defined initial angle position. The resetting device is responsive to an electrical signal received from the sensor.

Coin operated parking meter

Coins inserted into a parking meter are tested as to diameter, the presence of one or more holes and the content of ferromagnetic material. In the latter test, the coins are transported through a coin transport channel extending intermediate a coin-insertion location and a coin receptacle. The channel has a breadth which exceeds the thickness of the coins to be processed by an amount permitting coins passing through the channel to shift in direction transverse to the direction of their travel. A magnet arrangement attracts magnetically attractable coins into contact with a wall of the channel as such coins pass through the channel. A sensing arrangement controls the setting of a parking time in dependence upon whether coins passing through the channel are attracted into contact with the wall. The sensing arrangement includes a sensing member which extends into the coin transport channel so positioned and mounted as to be displaced to a predetermined position by a coin which during its travel is being magnetically held against the wall. The setting of a parking time is prevented unless the sensing member is caused to assume the predetermined position.

Coin testing arrangement for parking meters

A parking meter includes a timing unit, a coin receiver which can receive coins of different diameters, and a first and a second normally blocked lever which are biased for movement in mutually opposite directions about a joint axis of rotation into detecting engagement with a plurality of angularly spaced points on the circumference of the coin in the receiver, so as to detect the diameter of such coin. A manually operable arrangement serves to unblock the levers for their movement, and for subsequent joint angular displacement through a distance which is dependent upon the detected coin diameter. A control arrangement on one of the levers sets the timing unit to an interval whose length is a function of the aforementioned distance.
