ABSTRACT:
An electronic upgrading mechanism for upgrading a mechanical timing device comprising an electrical coin sensing mechanism which is installed abutting a coin carrier mechanism of a mechanical timing device for detection of actuation of a clock winding lever in communication with a coin carriage of the coin carrier mechanism; wherein the actuation of the clock winding lever is caused by a coin placed in the coin carriage wound into primary contact with alternative abutting cam surfaces such abuttal thereof providing an electrical contact with the electrical coin sensing mechanism, having at least one compatible contact thereon, each contact dedicated to the denomination of a coin; wherein the electrical coin sensing mechanism communicates with a programmable electronic digital timing control and display device which is installed within an upgraded mechanical timing device thereby replacing clocking and flagging mechanisms of the mechanical timing device.
