Definitions

  • a washer system for cleaning surfaces such as automobile headlights directs jets or shots of liquid from a nozzle against [52] the dirty surface;
  • the nozzle is spring-biased toward the sur- 51 1 nosb 1/10, B60 1 /4(, face to be cleaned, and each shot moves the nozzle by jet reac- [53] "239]2842224 tion from the start position near the-surface to a position farther away from the surface along a path such that the [56] References Cied sprayed area progressively increases concentrically outwardly.
  • the present invention relates to washer systems for cleaning surfaces, more particularly to surface-cleaning systems of the type in which a liquid is sprayed against the surface to clean the same.
  • Another object of the present invention isthe provision of such a system which is especially well adapted for cleaning the lenses of vehicle headlights.
  • FIG. 1 is an elevational view, with parts in cross section, of a system according to the present invention
  • FIG. 2 is a front elevational view of. the-structure. shown in FIG. 1;
  • FIG. 3 is an enlarged cross-sectional view of the spray head of the present invention.
  • FIG. 4 is a front view of a sprayer washerv included in the nozzle; v
  • FIG. 5 is a view similar to FIG. 3 but showing the baseor mounting about which the spray head swings.
  • FIG. 6 is an elevational view of the structure of FIGS, from the side opposite that which is shown in FIG. 1.
  • a vehicle headlight 1 having a conventional lens 2.
  • .'A support 3 is secured to the headlight mounting below lens2.
  • An arm 4 is mounted for vertical swinging movement on and relative to support 3 about a horizontal axis, theann-4 carrying a nozzle 5 at its upper end.
  • Nozzle 5 thus swings in a vertical plane which is perpendicular to the plane of the lens and which intersects the center of the lens.
  • the nozzle5 can have the structure shown in FIGS. 3 and 4.
  • the male comprises a head Shaving a shank with a vertical bore 9 therein for the reception of a tube 10 which can comprise the arm 4 or which can be carried by the arm 4.
  • Bore 9 communicates with another bore 11 at right angles thereto, the bore 11 receiving liquid from tube 10.
  • a seat 12 centers a star-shaped washer 13 (see FIG. 4) on the conical countersunk head of a screw 14 which is received in screwthreaded relation'in head 8.
  • Screw 14 is concentric with and is v surrounded by bore 11, so that liquid passing through tube 10 into bore 11 will escape about screw 14, and between the anus of the star-shaped washer 13, which is pressed against a corresponding conical seat in head 8 by the head of screw 14.
  • the conicity of washer 13 in its assembled position is preferably about 45.
  • a support 15 has a hollow screw-threaded nipple l6 thereon which can be screwed into the vehicle below the headlight or other surface to be washed.
  • the bore of nipple 16 continues in a channel 17 in support 15 itself.
  • An enlarged portion of channel 17 receives a hollow pivot 18; and for the purpose of assembling pivot 18 in support 15, one side of support 15 is removably closed by a cover 19 which is secured to support 15 by means of screws (not shown).
  • Pivot 18 has a pair of oppositely disposed trunnions which are coaxial with each other and with the bore through pivot 18, these trunnions being slidably rotatably received in nylon rings 20 one of which is mounted in support 15 and the other in cover 19.
  • a connector 21 extends radially outwardly from pivot 18 and receives the lower end of tube 10, which is the end of tube 10 that is opposite the a 2 end shown in FIG. 3. It is thus possible for tube 10 to swing about the axis of pivot 18, while remaining at all times in fluid .communication with a source of liquid under pressure (not shown) carried by the vehicle for introduction through nipple 1 v Piv'otl8 is normally urged counterclockwise as seen in F IG.
  • Themeans (not shown) for supplying liquid under pressure to the system described above may comprise any conventional high-pressure pump having an output pressure of, for example, 250 atmospheres, so that the discharge pressure from the nozzle will vary, depending on the position of the male, from an which electromagnet the belt pulley of the pump can be ap-.
  • the pump can, as is usual, have a pressure liquid reservoir and a valve mechanism arranged so that the valve opens at about atmospheres to discharge'about -4 cm. of liquid per shot. If the pump is operated continuously,
  • the nozzle When used as a headlight cleaner, it is preferable that when the nozzle swung farthest away from the lens, the area sprayed by the nozzle will not extend outwardly beyond the edges of the lens, thereby to conserve-the cleaning liquid.
  • area sprayed by the nozzle is preferably annular, but of course can be oval or rectangular or have other shapes.
  • This system can also be used for cleaning Windshields, and aids the function of the windshield wiper.
  • the system of the present invention tends to clean itself because it operates at high pressure.
  • a replaceable filter can be interposed in the liquid line.
  • antifreeze compound be added to the i d 0 liqu'idjalthough the device will be injured by freezing as the belt pulley driving the device would simply slip if the parts were frozen solid.
  • the outlet of the pump be connected by flexible tubing to thin copper tubes that extend up to nipple 16.
  • a surface-cleaningisystem comprising a noule, means mounting'the nozzle adjacent the surface to 'be-cleaned for said swinging movement toward and away from the surface to be cleaned, means for supplying liquid under pressure to the nozzle and for moving the nozzle away from said surface during ejection of liquid from the nozzle under the reaction force of the ejected liquid 'and for returning the nozzle to a position adjacent the surface after said ejection, whereby the area-f said surface which is sprayed by said nozzle increases progressively as the noule moves away from said surface during said ejection.
  • a system as claimed adjustably positioningthe nearest surface. 5. A system as claimed in claim 4, and further set screw means for adjustablypositioning the farthest position of said nozzle from said surface.
  • said mounting means comprising an upwardly extending arm that positions said nozzle in front of said'surface, and means mounting said'arm for vertical swinging movement about a horizontal axiswhich is disposed below said surface.
  • a system as claimed in claim 8 said nozzle directing said spray in a direction transverse to said am.
