Abstract
Abstract The headlight lens washer apparatus includes a fluid discharge tube supported for oscillating movement across the lens with one side thereof adjacent to and facing the lens. This facing side of the tube has a plurality of slit-like openings extended longitudinally of the tube and of relative lengths providing for a desired wash pattern on the surface area of the lens. The sheet-like sprays discharged from the tube act to concurrently remove and wash foreign material from the lens.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A washing system for the headlight lens of a vehicle having a front end portion for mounting a headlight comprising: a. an oscillatable tubular shaft mounted on said front end portion along side of said headlight having an extension projected laterally therefrom over said lens, b. said extension having a closed terminal end and a series of elongated fluid openings extended longitudinally of said extension in the side thereof facing said lens, said openings being of varying lengths and relatively spaced longitudinally of said extension to equalize the distribution of fluid discharged therefrom over the surface of said lens when said shaft is oscillated, c. said extension having a fluid passage with a cross sectional area greater than the combined area of said fluid openings, d. means for oscillating said tubular shaft to move said extension back and forth across said lens during a headlight washing operation, and e. means for supplying fluid under pressure to said shaft, concurrently with the oscillation thereof, for discharge through said openings onto said lens.
Claim 2
Dependent Claim
171 words
A washing system for the headlight lens of a vehicle having a front end portion for mounting a headlight comprising: a. an oscillatable tubular shaft mounted on said front end portion along side of said headlight having an extension projected laterally therefrom over said lens, b. said extension having a closed terminal end and a series of elongated fluid openings extended longitudinally of said extension in the side thereof facing said lens, said openings being of varying lengths and relatively spaced longitudinally of said extension to equalize the distribution of fluid discharged therefrom over the surface of said lens when said shaft is oscillated, c. said extension having a fluid passage with a cross sectional area greater than the combined area of said fluid openings, d. means for oscillating said tubular shaft to move said extension back and forth across said lens during a headlight washing operation, and e. means for supplying fluid under pressure to said shaft, concurrently with the oscillation thereof, for discharge through said openings onto said lens.
Claim 3
Dependent Claim
171 words
A washing system for the headlight lens of a vehicle having a front end portion for mounting a headlight comprising: a. an oscillatable tubular shaft mounted on said front end portion along side of said headlight having an extension projected laterally therefrom over said lens, b. said extension having a closed terminal end and a series of elongated fluid openings extended longitudinally of said extension in the side thereof facing said lens, said openings being of varying lengths and relatively spaced longitudinally of said extension to equalize the distribution of fluid discharged therefrom over the surface of said lens when said shaft is oscillated, c. said extension having a fluid passage with a cross sectional area greater than the combined area of said fluid openings, d. means for oscillating said tubular shaft to move said extension back and forth across said lens during a headlight washing operation, and e. means for supplying fluid under pressure to said shaft, concurrently with the oscillation thereof, for discharge through said openings onto said lens.
Claim 4
Dependent Claim
171 words
A washing system for the headlight lens of a vehicle having a front end portion for mounting a headlight comprising: a. an oscillatable tubular shaft mounted on said front end portion along side of said headlight having an extension projected laterally therefrom over said lens, b. said extension having a closed terminal end and a series of elongated fluid openings extended longitudinally of said extension in the side thereof facing said lens, said openings being of varying lengths and relatively spaced longitudinally of said extension to equalize the distribution of fluid discharged therefrom over the surface of said lens when said shaft is oscillated, c. said extension having a fluid passage with a cross sectional area greater than the combined area of said fluid openings, d. means for oscillating said tubular shaft to move said extension back and forth across said lens during a headlight washing operation, and e. means for supplying fluid under pressure to said shaft, concurrently with the oscillation thereof, for discharge through said openings onto said lens.
Claim 5
Dependent Claim
41 words
The washing system for the headlight lens of a vehicle according to claim 1 wherein: a. said extension is of an arcuate shape corresponding to the curvature of said lens with the concave side thereof adjacent to and facing said lens.
Claim 6
Dependent Claim
64 words
The washing system for a headlight lens of a vehicle according to claim 1 wherein: a. said fluid openings are relatively formed so that the central portion of the extension discharges a greater amount of fluid than either of the end portions thereof, and the end portion adjacent the shaft discharges of lesser amount of fluid than the end portion remote from said shaft.
