Description:
This invention relates to water mixing and distribution devices, and has particular reference to a mixing and portable discharge combination which may be used in place of the conventional faucets and spray head commonly used on kitchen sinks, washbowls in barber shops, and the like.
An object of the invention is to provide an integrated structure embodying the means for receiving hot and cold water, and discharging the mixed water through a portable spray head.
Another object of the invention is to provide an integrated water mixing and spray head which is readily adaptable to a conventional domestic three-hole sink, without the use of special tools and adapters.
Another object of the invention is to provide a device of the character indicated which is constructed and arranged in a way to obviate the necessity of using " O" rings and washers in the spout area.
Another object of the invention is to provide a device of the character indicated which is constructed and arranged so that it may be serviced with a great saving of time and labor.
Another object of the invention is to provide a device of the character indicated in which the water intake and mixing operations may be controlled with the fingers of one hand while the portable spray discharge head is manipulated by the other hand.
Another object of the invention is to provide novel means for the intake and mixing of hot and cold water.
Another object of the invention is to provide a device of the character indicated which is provided with a portable discharge spray suitable for washing and rinsing dishes in a conventional sink, or may be used for shampooing and rinsing hair in a barber shop, or the like.
Another object of the invention is the provision of a device of the character indicated which has a portable spray nozzle secured to the end of a flexible hose, whereby water may be discharged and sprayed upon objects remote from the sink or washbowl.
The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawing, forming part of the within disclosure, in which drawing:
FIG. 1 is a plan view of a device embodying the invention, with parts broken away parts shown in section, and other parts shown in broken lines, whereby to illustrate the relationship of the various elements.
FIG. 2 is a longitudinal section taken through the device shown in FIG. 1, and mounted on a conventional domestic kitchen sink.
FIG. 3 is a section taken substantially on the line 3-3 of FIG. 2.
FIG. 4 is a detail in section, showing the construction of the hot water valve and environments.
FIG. 5 is a modified form of hot water valve which may be employed with the device shown in FIGS. 1 and 2.
Referring now more particularly to the drawing, it will be understood that in the embodiment shown in FIGS. 1 and 2, the reference character 7 indicates, in general, the cover, or housing, for certain of the principal parts of the assembly. The housing 7 is preferably made of stainless steel, however, it may be made of anodized aluminum, plastic, or other suitable material.
In FIG. 2 I show the assembly as mounted on a conventional domestic kitchen sink 8, which is provided with conventionally spaced openings 9, 10 and 11, through which are extended certain parts of the invention assembly, as hereinafter described.
The invention device includes a water intake compartment 12, a mixing chamber 13, and a spray head 14, which includes an insulated handgrip portion 15 and a base portion 16.
The water intake compartment 12 is preferably circular in shape and has sidewalls 12A, bottom wall 12B and top wall 12C. The water intake compartment 12 has a center wall 12D which divides the compartment into a hot water chamber 17, and a cold water chamber 18.
Hot water enters the chamber 17 through a hot water line 19, and cold water enters the chamber 18 through a cold water line 20. The flow of water into and out of the hot and cold water chambers 17 and 18 is controlled by suitable valves 21 (Fig. 4) which valves are respectively manipulated by rockable levers 22 and 23, as hereinafter described. Each lever 22, 23 is pivoted as at 24, Fig. 4, to a bifurcated bracket 25 which is supported by the upper wall of the compartment 12. Each lever 22, 23 is provided at its lower end with a cam 26 (Fig. 4) which cam 26 is arranged to actuate the valve 21 to open and close the same when the lever is rocked on the pivot 24. Each valve 21 is spring biased as at 27, Fig. 4.
Cold water entering the compartment 18 is conveyed to the mixing chamber 13 through a tube 28, which communicates with an opening 29 in the partition wall 12D and the mixing chamber 13. Hot water is delivered to the mixing chamber 13 through a second tube 30, which communicates with an opening 31 in the sidewall 12A of the compartment 17 and the interior of the mixing chamber 13 as shown in Fig. 1. Each valve 21 (Fig 4) is provided with a suitable valve seat formed in the member 32 which is secured by any suitable means to the interior of the chamber 18.
Although I have described in detail the valve 21 in the compartment 18, it will be understood that a similar valving arrangement is carried in compartment 17. In Fig. 5 I show a modified form of valve and valve control in which the pivoted lever 33 is provided with a gooseneck 34, which is arranged to actuate the lever 35 which in turn actuates the valve 36 under the influence of a spring 37. This modification is a little more complicated than the structure shown in Fig. 4, so that I prefer to use the structure shown in Fig. 4.
Hot and cold water is carried through the tubes 28 and 30 to the mixing chamber 13, where it is thoroughly mixed to a suitable temperature. The properly tempered mixed water is then discharged into a flexible tube 38 which connects at its other end through fittings 39 to a neck 40, which communicates with the interior of the base member 16 which in turn connects through the handgrip portion 15 to the discharge spray head 14. As shown in FIG. 2, the handgrip portion is insulated with an outer covering 15A, and is provided with a central passage way 15B which communicates directly between the base member 16 and the spray head 14. The base member 16 is provided with a concave bottom wall 16A which engages a convex seat 16B formed in a plastic ring 41 through the center, through which slidably extends the neck 40. The opening in the ring 41 is sufficiently large enough to permit the neck 40 and the fittings 39 and the hose 38 to slide so that the spray head 14 may be transported about at will. The mixing chamber 13 is provided with a depending threaded extension 13A arranged to receive a washer 13B and a locknut 13C as shown in FIG. 2. The member 12 is provided with a similar depending threaded extension 12E which is also adapted to receive a washer 12F and a locknut 12G.
It is believed that the operation of the device is obvious from the foregoing description.
