Abstract

Abstract An improved nozzle means for spraying washer fluid on the surface of an automobile windshield, the nozzle means being arranged for use in combination with an automobile windshield wiper and washer system, the wiper being the standard reciprocating wiper, the washer system including a reservoir to retain a supply of washer fluid, and pressure means to provide a source of such fluid under pressure. Conduit means are arranged to deliver fluid under pressure to said nozzle means. The nozzle means comprises a head having an inlet port and a plurality of outlet ports, with the plurality of outlet ports being generally equally arcuately spaced, one from another, and being disposed so as to impinge upon the surface of said wiper at spaced intervals thereon. Bracket means are provided for mounting the nozzle means on the back of the wiper blade assembly.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 260 words
In combination with an automobile windshield wiper washer system having a reciprocating windshield wiper, a reservoir to retain a supply of washer fluid, pressure means to provide a source of such fluid under pressure, and port means establishing communication with said source of pressurized fluid, said windshield wiper consisting of a wiper blade and a generally rigid backing frame therefor extending substantially coextensive with the wiper blade, the improvement comprising: a. nozzle means, bracket means attaching said nozzle to said backing frame and conduit means coupling said port means to said nozzle means; b. said nozzle means comprising a head, an inlet port to said nozzle means, a plurality of outlet ports, and bore means in said head extending between said inlet port and a chamber area, with said chamber area being in communication with a plurality of outlet passageways, each passageway terminating in one of said plurality of outlet ports, said plurality of outlet ports being generally equally arcuately spaced, one from another, and being disposed so as to impinge fluid directly onto the surface of said windshield along a plane transverse to the windshield surface and at spaced intervals thereon; c. said conduit means being in communication with the inlet port of said nozzle means; and d. said bracket means comprising first and second generally Lshaped telescoping members, one of said telescoping members having a flanged upright leg for receiving and confining the corresponding and generally planar leg of the other, and with said nozzle means being secured to the base leg of one of said telescoping members.
Claim 2
Dependent Claim 260 words
In combination with an automobile windshield wiper washer system having a reciprocating windshield wiper, a reservoir to retain a supply of washer fluid, pressure means to provide a source of such fluid under pressure, and port means establishing communication with said source of pressurized fluid, said windshield wiper consisting of a wiper blade and a generally rigid backing frame therefor extending substantially coextensive with the wiper blade, the improvement comprising: a. nozzle means, bracket means attaching said nozzle to said backing frame and conduit means coupling said port means to said nozzle means; b. said nozzle means comprising a head, an inlet port to said nozzle means, a plurality of outlet ports, and bore means in said head extending between said inlet port and a chamber area, with said chamber area being in communication with a plurality of outlet passageways, each passageway terminating in one of said plurality of outlet ports, said plurality of outlet ports being generally equally arcuately spaced, one from another, and being disposed so as to impinge fluid directly onto the surface of said windshield along a plane transverse to the windshield surface and at spaced intervals thereon; c. said conduit means being in communication with the inlet port of said nozzle means; and d. said bracket means comprising first and second generally Lshaped telescoping members, one of said telescoping members having a flanged upright leg for receiving and confining the corresponding and generally planar leg of the other, and with said nozzle means being secured to the base leg of one of said telescoping members.
Claim 3
Dependent Claim 25 words
The combination as defined in claim 1 being particularly characterized in that said flanged leg is adapted for press-fit engagement with said generally planar leg.
Claim 4
Dependent Claim 27 words
The combination as defined in claim 2 being particularly characterized in that said bracket means is adapted for mounting generally adjacent the center of said backing frame.
