ABSTRACT:
A drive shaft is interposed between the speedometer and odometer and the speedometer cable of an automotive vehicle and coupled to and rotatable therewith in a manner whereby the drive shaft rotates at the same speed as the cable. A cam shaft is rotatably mounted in operative proximity with the drive shaft and is coupled thereto by gears. A cam wheel is affixed to and rotatable with the cam shaft. The cam wheel has a cylindrical rim and a cam mounted on the rim and extending therefrom. The cam shaft is coupled to the drive shaft for rotating the cam wheel one revolution per unit distance. Electrical contacts in operative proximity with the cam are in spaced open relation out of electrical contact when spaced from the cam. The cam causes the electrical contacts to move into electrical contact once per revolution of the cam wheel thereby closing the electrical contacts once per unit distance represented by a revolution of the cam wheel. A two-way counter is electrically connected to the electrical contacts via a manually-operated two-position switch and counts one count up when the switch is in one of its positions and each time the electrical contacts are closed and counts one count down when the switch is in the other of its positions and each time the electrical contacts are closed. An indicator coupled to the counter indicates the count of the counter and thereby a desired distance.
