Abstract
A winshield washer apparatus (10) for removable attachment to a wiper blade (12) in a substantially parallel contiguous relationship for oscillation with the wiper blade (12) is disclosed. The washer attachment (10) includes an elongated member (14) defining a generally U-shaped cross section and including adjacent one side thereof a tubular portion (16) extending the longitudinal extent of the elongated member (14), the tubular portion (16) defining a plurality of apertures (18) therein. The elongated member (14) further includes adjacent an opposite side thereof, a U-shaped channel portion (20) extending longitudinally of the elongated member (14). An elongated, hollow tubing (22) removably retained by the U-shaped channel portion (20) is interconnected at one end to an open end of the tubular portion (16) and at the other end to a conduit from a cleaning solution source. Accordingly, the washer attachment (10) of the present invention may be interconnected to a cleaning solution source and removably attached to the wiper blade (12) for oscillation therewith so as to deliver cleaning solution directly onto the surface of the windshield.
