Abstract
Abstract Two embodiments of an assembly for directing a fluid, such as a combination of air and a liquid, toward a vehicle headlamp for cleaning the headlamp surface. A support member is adapted at a first end to be connected to a vehicle body adjacent a headlamp and extends to a forward end which supports a nozzle guide or cage member. The assembly includes an elbow member having a fluid inlet and support flanges for receiving retaining fasteners. A supply tube is connected to the inlet of the elbow. The elbow member has an outlet which extends transversely of the inlet and a flailing flexible tube is connected to the outlet and has a loop integral therewith extending about the elbow member for retaining the flailing tube thereon. The cage member has a terminal end defining an opening and is of generally funnel shape for restricting the flailing movement of the emitting end of the flailing tube. In the second embodiment a cover is disposed over the cage member. The cage members have walls defining a throat surrounding the flailing tube with generally parallel walls below the throat and diverging walls above the throat. The diverging walls are generally V-shaped in cross section adjacent the opening of the cage member and the diverging walls are interconnected by generally parallel connecting walls. Such a cage member configuration results in very effective flailing movement of the flailing tube.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
156 words
An assembly for directing fluid toward a surface comprising; a flexible tube having an emitting first end for emitting fluid and for flailing in response to such emission of fluid from said emitting end and an anchored second end, cage means defining an opening surrounding said emitting end of said tube and in spaced relationship thereto for restricting the flailing movement of said tube, said cage means defining a throat spaced from and between said anchored end of said tube and said emitting end of said tube so that said cage means diverges from said throat whereby the flailing movement of said tube is more restricted between said throat and said anchored end than between said throat and said opening which surrounds said emitting end of said tube, said cage means including a cross section having spaced walls with parallel portions in a direction extending upwardly toward said emitting end of said tube to said throat.
Claim 2
Dependent Claim
156 words
An assembly for directing fluid toward a surface comprising; a flexible tube having an emitting first end for emitting fluid and for flailing in response to such emission of fluid from said emitting end and an anchored second end, cage means defining an opening surrounding said emitting end of said tube and in spaced relationship thereto for restricting the flailing movement of said tube, said cage means defining a throat spaced from and between said anchored end of said tube and said emitting end of said tube so that said cage means diverges from said throat whereby the flailing movement of said tube is more restricted between said throat and said anchored end than between said throat and said opening which surrounds said emitting end of said tube, said cage means including a cross section having spaced walls with parallel portions in a direction extending upwardly toward said emitting end of said tube to said throat.
Claim 3
Dependent Claim
28 words
An assembly as set forth in claim 1 wherein said walls extend through said throat and into diverging portions which diverge toward said opening of said cage means.
Claim 4
Dependent Claim

An assembly as set forth in claim 2 wherein said walls are curved between said parallel portions and said diverging portions thereof.
Claim 5
Dependent Claim
31 words
An assembly as set forth in claim 2 wherein said diverging portions extend to said opening of said cage means and are each generally V-shaped in cross section adjacent said opening.
Claim 6
Dependent Claim
30 words
An assembly as set forth in claim 4 wherein said walls are oppositely disposed relative to one another with the apexes of said V shapes pointing away from one another.
Claim 7
Dependent Claim
25 words
An assembly as set forth in claim 5 wherein said cage means includes connecting walls interconnecting at least said diverging portions of said spaced walls.
Claim 8
Dependent Claim

Claim 10
Dependent Claim
91 words
An assembly for directing fluid toward a surface comprising; a flexible tube having an emitting first end for emitting fluid and for flailing in response to such emission of fluid from said emitting end and an anchored second end, cage means defining an opening surrounding said emitting end of said tube and in spaced relationship thereto for restricting the flailing movement of said tube, said cage means defining spaced and opposed walls on opposite sides of said tube, each of said walls being generally V-shaped in cross section adjacent said opening.
Claim 11
Dependent Claim
91 words
An assembly for directing fluid toward a surface comprising; a flexible tube having an emitting first end for emitting fluid and for flailing in response to such emission of fluid from said emitting end and an anchored second end, cage means defining an opening surrounding said emitting end of said tube and in spaced relationship thereto for restricting the flailing movement of said tube, said cage means defining spaced and opposed walls on opposite sides of said tube, each of said walls being generally V-shaped in cross section adjacent said opening.
Claim 12
Dependent Claim
17 words
An assembly as set forth in claim 9 wherein said spaced walls are interconnected by connecting walls.
Claim 13
Dependent Claim
