Inventors:
William J. Hartery - Lexington MA
International Classification:

Abstract:
The present invention relates to a windshield cleaning system and more particularly to a windshield cleaning system which utilizes both an oscillating wiper blade and a washer fluid system for transporting the washer fluid through the blade to outlets in the upper portion of the blade to clean the outer surface of the windshield.

The body and the spline member cooperatively form elongated liquid passageways in the body. A flexible contact member extends downwardly from the elastic body to contact the windshield.
