Abstract
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.
