## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a division of and claims priority to a parent application entitled “Directional Atomizer System For Cleaning Chandeliers” filed by the same inventor on Jun. 17, 2010, application Ser. No. 12/817,625 now U.S. Pat. No. 8,402,596, which application is hereby incorporated by reference.


BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates, generally, to the art of cleaning chandeliers or other structurally complex lighting fixtures. More particularly, it relates to a system that cleans lighting fixtures without chemicals and that protects the electrical parts of the fixture from water and chemicals.
2. Description of the Prior Art
Conventional chandelier cleaning requires a labor-intensive, time-consuming dismantling of the chandelier and hand-washing of each part.
Conventional spray bottles rely on gravity to remove mixtures of chemicals, cold water, and dirt from the chandelier crystals and out of pooling areas. The area below a crystal or other chandelier part being cleaned is therefore soaked as that water drips. The floor or other surfaces such as tabletops below the part being cleaned must therefore be covered with a tarp or drop cloth. Floors and walls can still be marred by water as it splashes onto such tarps or drop cloths. The water, which may contain dissolved chemicals, may also damage the floor simply by flowing off the tarp or drop cloths because such protective sheets have little or no water containment ability.
Thus there is a need for cleaning chandeliers that does not depend upon the force of gravity and which does not result in pooling of water under a part that is cleaned.
Most manufacturers of spray bottle chemical chandelier cleaners warn users to avoid fume and spray inhalation, eye contact, skin contact, and the like.
Thus there is a need for a cleaning method that is safe to use.
Most chandelier arms, both new and antique, are held to the main frame of the chandelier by a potting material. Water is used to weaken the bond provided by the potting material when a chandelier arm is intentionally removed. Complete saturation of the potting material by chemical sprays also weakens the bond and loosens such arms when there is no intention to change them.
Thus there is a need for a process of cleaning chandeliers that does not use chemical sprays that weaken the bond of potting material.
There is also a need for a cleaning apparatus that can clean crystal parts of a new generation of fixtures that include crystals that are mounted in upright, diagonal, and sideways configurations, and the like.
Adhesives are also used on newer fixtures to bond glass, crystals, and other parts directly to the chandelier. These adhesives may or may not be weakened by chemical cleaning sprays. However, clear epoxy may be softened and discolored over time by the application thereto of chemical sprays.
Thus there is a need for a cleaning process that does not weaken adhesive bonds and that does not soften or discolor the clear epoxy used in chandeliers.
The use of a chemical spray bottle to clean a fixture requires spraying and re-spraying until the entire chandelier is drenched. Plastic bags are used to cover the bulb sockets. However, water and chemicals still pool in electrical junction boxes within the fixture and bowls that are common in chandeliers, thereby causing electrical shorts, corrosion, rusting, and other damage. The water can remain in such pools for days or weeks.
Thus there is a need for an improved method of cleaning chandeliers that does not cause such pooling.
However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill how the identified needs could be met.
SUMMARY OF THE INVENTION
The long-standing but heretofore unfulfilled need for an improved method and apparatus for cleaning chandeliers and light fixtures is now met by a new, useful, and non-obvious invention.
The novel hand-held tank for holding hot water includes a base atop which is mounted the hand-held tank. The base has a hollow interior, and the tank has sidewalls, at least one of which is transparent.
An air and water pump and a battery are mounted in the hollow interior of the base, the battery being in electrical communication with the pump.
A first inlet admits ambient air into an inlet of the pump and a second inlet admits water into the inlet of the pump.
At least one air and water-emitting nozzle is formed in a sidewall of the tank and a pump outlet is in open fluid communication with the at least one water-emitting nozzle.
Said at least one water-emitting nozzle discharges agitating water and bubbles into the hot water or above the water line, depending upon the depth of the water, to help dislodge chemicals and grease from the chandelier parts immersed in the hot water.
An interior surface of at least one sidewall is covered with splash-suppressing bristles.
A cut out area of predetermined shape is formed in a preselected sidewall of the tank and a door panel is disposed in the cut out area, said door panel being made of an flexible and resilient elastomeric material and having a frame made of a substantially rigid material.
The flexible and resilient soft rubber conforms to the shape of a chandelier arm and closes around the arm tightly to prevent hot water emitted under pressure by the jet gun from passing through the door panel.
A sump is formed in the base and an impeller is mounted for rotation in the sump. A motor is mounted in the hollow interior of the base, said motor in electrical communication with said battery. Rotation of the impeller agitates the hot water in the tank.
An important object of the invention is to provide a chandelier cleaning apparatus that does not employ chemicals.
Another important object is to provide a chandelier cleaning apparatus that does not require the chandelier to be disassembled during cleaning.
Yet another important object is to provide a hands-free, touch free chandelier cleaning apparatus.
These and other important objects, advantages, and features of the invention will become clear as this description proceeds.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the description set forth hereinafter and the scope of the invention will be indicated in the claims.



BRIEF DESCRIPTION OF THE DRAWINGS
For a fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description, taken in connection with the accompanying drawings, in which:
FIG. 1 is a perspective view of the novel tank; and
FIG. 2 is a side elevational view of a variation of the FIG. 1 embodiment.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
An embodiment of the novel quaff that provides a two-stage cleaning process is depicted in FIGS. 1 and 2. It is not referred to as a vacuum shield because the term “shield” implies a flat, substantially two-dimensional object whereas the quaff of FIGS. 1 and 2 includes a three-dimensional tank that holds hot water. Quaff 74 may be hand-held as depicted or it may be mechanically mounted on a suitable support means such as an upstanding pole or post, not depicted.
Quaff 74 includes base 76 atop which is mounted tank 78 having sidewalls 78a, 78b, 78c and 78d, one or more of which may be transparent. This embodiment of quaff 74 substantially eliminates the need for a drain hose because water from nozzles 82a, 82b, and 82c accumulates in tank 78.
Air and water pump 80 is mounted in the hollow interior of base 76, together with battery 82 that provides power to pump 80 so that quaff 74 can be easily maneuvered without the impediment of a power cord. Inlet 80a admits ambient air into the inlet of pump 80 and inlet 80b admits water into said inlet of said pump. Pump outlet 80c is in open fluid communication with nozzles or jets 82a, 82b, and 82c that discharge agitating water and bubbles into the hot water or above the water line, depending upon the depth of the water, having surface 81 in tank 78, to help dislodge chemicals and grease from the chandelier parts immersed in said hot water as depicted. Switch actuator 80d is pressed to turn pump 80 on or off.
Bristles 60 and doors 64 perform the same function in this embodiment as performed in the two-dimensional version of quaff 74 as disclosed in the incorporated application.
As water from jet gun 14 accumulates within tank 78, vacuum hose 84 serves as a drain intake, keeping the water level substantially constant and removing water from the tank so that the tank water remains hot. Vacuum hose 84 also serves to skim floating dust or debris from the surface of water 84. Vacuum hose 84 is optional equipment and is not often needed because tank 78 will not approach full capacity on most chandelier cleaning jobs.
Further agitation may also be provided by fan or impeller 86, depicted in FIG. 2. Said impeller 86 is preferably positioned in a screen-covered sump at the bottom of tank 78 so that it agitates the hot water in tank 78 when rotated by battery-operated motor 83. In the variation of FIG. 2, water outlet 80c of pump 80 is in open fluid communication with the hot water in tank 78 and jet nozzles 82a, 82b, and 82c are not used. However, both embodiments are within the scope of the invention and both embodiments may be used in conjunction with or without impeller 86.
As depicted in FIG. 1, it is clear that immersed crystals 18 are cleaned by the agitated hot water in the absence of chemicals. Hot water is advantageously poured into tank 78 at the beginning of the cleaning process to a shallow depth so that a horizontal section 18a of crystal 18 is pre-soaked. Moreover, as crystals 18 are lifted from the hot water as quaff 74 is lowered, they are rinsed above water surface 81 by jet gun 14. If water level 81 is high as depicted, crystals 18 may be rinsed by jet gun 14, by nozzle 82c, or both. If water level 81 is below nozzle 82b, that nozzle may also serve to rinse the crystals. If water level 81 is very low, nozzle 82a may also provide rinsing. Crystals 18 thereby receive an under water pre-soaking as well as an above water rinsing. This two step cleaning process effectively removes chemicals and grease.
The novel apparatus has many advantages. It enables a chandelier to be cleaned much faster than conventional methods because the user need not touch or remove any of the crystals. Moreover, it cleans areas that cannot be accessed by other cleaning systems or hand-cleaning unless crystals are removed. Crystal removal is very undesirable because chandeliers may have as few as one hundred (100) parts or as many as one hundred thousand (100,000) parts.
The novel method also avoids the use of chemical sprays. Such sprays can break down the lacquer coating that protects the metallic parts of the chandelier, thereby enabling corrosion and darkening of the metallic surfaces over time.
It also eliminates the prior art need to protect light bulbs and electrical sockets to protect them from water, thereby saving even more time.
It will thus be seen that the objects set forth above, and those made apparent from the foregoing description, are efficiently attained and since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention that, as a matter of language, might be said to fall therebetween.
