Abstract

In a preferred form, this disclosure relates to a windshield cleaning system wherein washer fluid is continuously circulated by a pump from a reservoir through a flexible wiper blade and back to the reservoir. The wiper blade is mounted for oscillating movement across the outer surface of the windshield and has a passage therethrough in communication with the other surface of the windshield through which the washer fluid continuously circulates. The wiper blade has lip portions which engage the outer surface for wiping the same end for substantially preventing leakage of the washer fluid circulating through the passage between the wiper blade and the windshield. The windshield is cleaned by virtue of the contact of the continuously circulating cleaning fluid and the engagement of the wiper blade moving thereacross.

Claims

1. A windshield cleaning system for cleaning the outer surface of a windshield comprising:

an enclosed cleaning fluid supply;

wiper means having a pivoted wiper arm for oscillating movement across said windshield surface, said wiper means including a wiper blade of flexible material, said wiper blade having an upper portion and a pair of spaced lip portions integral with the upper portion and contacting said windshield surface for substantially the entire length of said wiper blade;

said wiper blade having upper and lower end portions for enclosing the ends of said wiper blade between said lip portions;

said upper portion, lip portions, and end portions of said wiper and said windshield surface disposed between said lip portions defining a passage therebetween, said passage having an inlet at its upper end portion and an outlet at its lower end portion to have cleaning fluid continuously circulated throughout its length;

said lip portions of said wiper blade wiping said windshield surface and said lip portions and said end portions substantially preventing leakage of said cleaning fluid from said passage between said wiper blade and said windshield surface;

conduit means including pump means to provide for continuous circulation of said cleaning fluid from said supply, through said wiper blade, and back to said supply whereby said windshield surface is cleaned by the contact of the continuously circulating cleaning fluid and the engagement of the moving wiper blade across the windshield;

a relief valve operatively connected with the system to exhaust any air entering the system; and

a filter for filtering said cleaning fluid being circulated through said system.
