Abstract
A windshield wiper is provided with at least one wiper blade having angularly disposed channels therein and with a hollow tube having openings communicating with these channels, the tube extending longitudinally along the wiper. Hollow feed tubing connected with the tube receives washer solvent under pressure. The solvent flows out of the channels in the blade onto the windshield to enable the wiper to perform washing and wiping actions simultaneously.
Claims2
A windshield wiper and washer device comprising, in combination:
- a rigid longitudinally elongated back member having a generally U-shaped transverse cross-section defining a leading edge, a trailing edge, and opposed opposite end wall members;
- a flexible longitudinally elongated wiper blade having a substantially flat top surface, a sloping front surface, a sloping back surface, and a pair of opposed end surfaces;
- the wiper blade removably affixed to the back member between the leading and trailing edges thereof and extending completely between the opposite end wall members thereof so as to define therewith a confined passageway between the back member and the top surface of the wiper blade;
- a plurality of spaced apart channels each extending completely through the wiper blade from the top surface thereof to the outer front surface thereof;
- said channels each having a front discharge opening formed along the blade front surface at each channel outer end;
- a hollow solvent feed tube disposed in the confined passageway along the back member and extending longitudinally therealong centrally thereof and terminating adjacent and inwardly from the back member opposite end wall members;
- a series of spaced apart openings disposed in the feed tube in the direction of the blade member top surface for dispensing solvent from the tube to the channels in the blade member;
- a plurality of bracket members secured to the back member extending outwardly therefrom into the passageway, the bracket members being disposed along the axis of the back member in alignment with each other, the bracket members securing the feed tube to the back member;
- a generally T-shaped connector means disposed substantially centrally of the hollow feed tube and in fluid communication therewith, the arms of the T being connected to the feed tube with the body of the T projecting outwardly of the back member in a direction opposite from the position of the blade member;
- a flexible hinge defining element of a hollow tubular construction having one end affixed to the projecting portion of the T-shaped connector means for delivering solvent thereto;
- a hollow tubular shaped linkage arm member having one end affixed to the free end of the flexible hinge element for the purpose of moving the back member and wiper blade back and forth across a windshield, the linkage being hollow and in fluid communication with the flexible hinge to pass solvent under pressure therethrough;
- a plurality of spray heads associated with some of the openings of the feed tube;
- the wiper blade comprising two end blades and a plurality of smaller blade elements disposed therebetween and extending longitudinally parallel thereto;
- and
- whereby solvent can be supplied through the linkage arm member, through the hinge member, through the connector, through the feed tube, through the channels, and out of the channels front discharge openings onto the windshield to form an even coating of dispensed solvent in the path of the wiper blade for cleaning the windshield.
