Claim:
An automobile windshield wiper system comprising: an electric motor operably coupled with a primary drum, wherein the motor generates rotation of the primary drum; a primary pivot shaft having a first end coupled to the primary drum and a second end coupled to a first windshield wiper, wherein rotation of the primary drum generates rotation of the primary pivot shaft, and wherein rotation of the primary pivot shaft generates rotation of the first windshield wiper; a secondary drum; a secondary pivot shaft having a first end coupled to the secondary drum and a second end coupled to a second windshield wiper; a cable assembly comprising at least one cable operatively associated with the primary drum and the secondary drum, wherein rotation of the primary drum generates a pulling movement of the cable assembly, and wherein the cable assembly movement generates rotation of the secondary drum, the secondary pivot shaft, and the second windshield wiper; a primary pivot housing fully enclosing an outer periphery of the primary drum to define a primary interior portion, and a secondary pivot housing fully enclosing an outer periphery of the secondary drum to define a secondary interior portion, wherein the primary and secondary drums include a respective key, and wherein the interior portions of the primary and secondary pivot housings include a respective protrusion that associates with the respective key to restrict the rotation of the primary and secondary drums.
