ABSTRACT:
An elongated track receives and supports a movable wiper arm carriage having a windshield wiper extending therefrom. A plurality of pulleys couple the wiper arm carriage to an oscillatory drive mechanism having a reciprocating carriage. The pulley and cable system provides a distance multiplication in which the wiper arm carriage moves a substantially greater distance in response to motion of the oscillatory system carriage. A single direction drive motor is coupled to the oscillatory drive which includes a rotating arm together with a pivotally supported connecting arm and slider coupled to a guide bar supported upon and coupled to the oscillatory system carriage.
