WINDSHIELD CLEANING APPARATUS Filed May 9, 1955 2 Sheets-Sheet 2 fave/Mar MAW/2777f. arr/50f United States Patent WINDSHIELD CLEANING APPARATUS William Edward OShei, London, England Application May 9, 1955, Serial No. 506,765
Claims priority, application Great Britain May 11, 1954 7 Claims. (Cl. 239305) The present invention relates to windshield cleaning apparatus of the kind comprising one or more nozzles through which water or other liquid may be discharged on to the windshield in the path of movementof the windshield wiper blades in order to clean mud and dirt fromthe windshield. The cleaning liquid, which somerespectively associated with the containers, the two pump,
outlets being connected to the common nozzle or nozzles through two non-return valves respectively.
The two containers may be constituted by separate vessels or by two separate compartments of a common vessel.
In another embodiment of the invention, a common discharge pump or the like is used in association with a changeover valve for selecting the liquid to be sprayed.
Alternatively, non-return valves may be connected in the passages between the two containers and the common nozzle or nozzles, means being provided for selectively feeding the contents of the containers to the common nozzle or nozzles. The container may comprise a flexible walled bottle, for example a polyethylene bottle, from which the contents can be discharged by compressing the bottle.
In operation the concentrated detergent is first discharged on to the windshield and after a few strokes of the wiper blade the normal cleaning solution may be discharged if this should be necessary.
The discharging means may be so constructed or arranged that the concentrated detergent and the normal cleaning solution will be automatically discharged in the correct sequence at each operation of the discharge means.
The apparatus according to the invention enables two different liquids to be separately and selectively discharged on to the windshield through the same nozzle or nozzles. According to a feature of the invention, one of these liquids comprises a strong or concentrated solution of a detergent, and the other liquid comprises water or a dilute cleaning solution. I have found that a concentrated detergent solution not only more readily loosens the film of mud and grease on the windshield than does water or a dilute solution, but that it also loosens the mud and grease which adheres to the wiping edge of the wiper blade squeegee element, so that by first discharging the concentrated detergent on to the windshield the mud and grease on the screen and squeegee element is quickly loosened so that the subsequent discharge of water or dilute solution will more easily wash away the mud and grease andja clear wipe will be more quickly obtained than is possible by the use of water or a dilute solution alone. Thecleaning of the wiping edge of the squeegee element itself by theconcentrated detergent, which is not easily effected by water or a dilute solution alone, enables the squeegee element better to adhere to the glass and thus effect a cleaner wipe.
In order that the invention may be more clearly understood, reference will now be made to the accompanying drawings, in which:
Fig. 1 is a view of one embodiment of the invention.
Fig. 2 is a view showing a modification.
Fig 3 is a view showing a further modification.
Referring to the embodiment shown in Fig. 1, the apparatus comprises two liquid containers 1, 1a from which the liquids, may be discharged by pumps 2, 2:: respectively through nozzles 3 which are common to botlrsystems. As. both systems are identical only. one will be described. in detail, corresponding elements of the other systembeing indicated by the same reference numbers but with the suffix a.
The. container 1 is provided with a cover 4. which carries a check valve fitting 5 having three tubular connections 6, 7 and 8 for rubber tubes 9, 10 and 11 respectively.
' Tube 9 depends from thefitting 5 into the container 1 and is provided with a strainer 12v at its .lower end. The passage into the fitting 5 from the connection 6 is controlledby anon-return ball valve 13 resting on the seating 14. Tubev It). connects witha T-piece 15., to Which is also connected the corresponding tube,v 10a of the other systern, which in turn is connected by a rubber tube 16 to a second T-piece. 17 which feeds the two nozzles 3 which are mounted in front of the vehicle windshield and so disposed that the liquid discharged therefrom will besprayed on to. the windshield in the paths of movement of two. wiper blades. The passage from the fitting 5 to the connection 7 is controlled by a non-return ballvalve l8 resting on the seating 19.
The space in thefitting 5 between the two ball valves,
13 and 18 leads to the connection 8 which is connected by the tube 11 to the pump 2. The pump 2 may comprise a diaphragm which may be actuated by depressing the knob 20 by the hand or the foot, the diaphragm being returned by a spring.
Operation of the pump 2 causes the liquid in the container 1 to be sucked up, during the return movement of the pump, through the tube 9, valve 13 and tube 11 into the pump 2 (the valve 18 being closed at this time) and to be discharged, during depressing the knob 20, through the tube 11, valve 18, tube 10, T-piece 1'5, tube 16, T-piece 17 and the nozzles 3. The valve 13 remains closed at this time, and the liquid is prevented from being forced back into the container 1a by the column of liquid in the tube 10:: which is retained therein by the valve 18a.
Liquid in the container 1a can be similarly discharged through the same nozzles 3 by operating the pump 2a, the valve 18 and the column of liquid in the tube 10 preventing the liquid from the container 1a from being forced back into the container 1.
The containers 1 and 1a are respectively partially filled with a concentrated solution of a detergent and clear water or a dilute cleaning solution as normally used in windshield cleaner apparatus. In using the apparatus, pump 2 is first operated to discharge concentrated detergent on tothe windshield, and after a few strokes of the wiper blade pump 2a is operated to discharge water or the normal cleaning solution on to the windshield.
If desired, non-return valves may be incorporated in or associated with the T-piece 15. to prevent liquid forced up one of the tubes 10, 10m from being forced into the other tube; these valves may be additional to or instead Fig. 2 shows a modification of Fig. 1 in which only a single pump is provided and arranged for selectively discharging the liquid from both containers.
The arrangement comprises the two ars 1, 1a and associated check valve fittings 5, 5a, which are connected to the nozzles 3 in the same way as described with reference to Fig. 1. The connections 8, 8a of the two check valve fittings are, however, connected by rubber tubes to two connections 21, 21a of a changeover valve 22 which may be conveniently in the form of a plug cock, the rotary element 23 of which is provided with a right-angle connecting passage 24 whereby, by turning the member 23 through a right angle, the connections 21, 21a may be selectively connected to a connection 25 which is connected by a rubber tube 26 to the common pump 2.
When the plug cock member 23 is in the position shown in the drawings, operation of the pump 2 will suck up liquid from the container 1 and discharge it through the nozzles 3. By turning the member through a right angle to connect the connection 21a to the connection 25, operation of the pump 2 will suck up liquid from the container 1a and discharge it through the nozzles 3.
Fig. 3 shows a modification of Fig. 2, in which the check valve fittings 5, 5a are dispensed with and the pipes 9, 9a are directly connected to the connections 21, 21a respectively of the changeover valve 22. The connection 25 leads to a check valve fitting 5b which is in all respects similar to the check valve 5 and contains ball valves 13b and 18b, the connection 8b leading via the rubber tube 11b to the pump 2 and the connection 71; leading via the rubber tube b directly to the T-piece 17 leading to the nozzles 3. With this arrangement, the liquids in the containers 1 and 1a will be selectively discharged upon operating the pump 2 depending upon the position of the plug cock member 23 of the changeover valve 24.
Whilst particular embodimentshave been described, it will be understood that various modifications may be made without departing from the scope of the invention. Thus, for example, the container for the concentrated solution may be of smaller capacity than that of the container for the normal cleaning solution. Further, the quantity of concentrated detergent discharged at each operation may be less than the quantity of normal cleaning liquid discharged at each operation.
In another embodiment, the concentrated and normal cleaning fluids may be accommodated in a container made of a resilient or flexible plastic material and provided with a partition for dividing the container into two compartments for containing respectively the concentrated and normal cleaning solutions. The container may conveniently be constructed in the form of a flexible bag, somewhat resembling a rubber hot-water bottle in shape, the interior of which is divided into two compartments with separate outlets through the, neck for the concentrated and normal cleaning solutions. The two outlets may be provided with shut-off valves. The liquids can be selectively ejected from the two compartments either by compressing the walls of the container with one or the valves closed or by a manual or foot-operated pump device for selectively discharging the liquids from the compartments, for example in any of the manners above described.
