It has heretofore been proposed to employ time
meters for parked automobiles and it is the object
of this invention to overcome certain defects in
the known devices of this character and to em
ploy a device which will throw into action an
electric light, the illumination of which will be
continued for a predetermined time.
Speci?c objects of the invention will be set
forth in the accompanying specification with ref
erence to the drawings, in which:

a coin is released from the timing rotor and the

the insertion of a third coin.
It will be understood that the embodiment of
