Abstract
A wax candle (10) positioned below a wax reservoir (30), which is held in position above candle (10) by a wax reservoir support (20). While burning, the heat emitted from the flame of candle (10) causes the wax contained in reservoir (30) to slowly and continuous melt. This melted wax drips down from reservoir (30) into candle (10) and replenishes the wax used for combustion on the wick of candle (10). The rate of this replenishment and the flame size of candle (10) are self regulating, and in direct relationship with each other during cycle outlined below:An increase in flame size causes a subsequent increase in replenishment.An increase in replenishment causes a subsequent decrease in flame size.A decrease in flame size causes a subsequent decrease in replenishment.A decrease in replenishment causes a subsequent increase in flame size.And the cycle begins again.This regulation of dispensed wax allows the surface level of candle (10) to remain relatively constant and does not “burn down” as a traditional candle's would. Therefore, by replacing the wax in reservoir (30) as needed, this candle can be used indefinitely.

in the center of candle wax


13


with the axis of wick


16


in a vertical orientation. In the preferred embodiment, this keeper


14


is a separate component comprised of a ten centimeter long and twenty-four millimeter wide piece of metal strap, commonly referred to as “pipe strap”. This strap is bent as follows which allows it to remain stable while resting on its edge; one half of the metal strap's length is bent into a triangle configuration, thus forming a drip diffuser cradle


14


T, the remaining two inches of strap is bent into a spiral form, thus forming a wick arm


14


W. Wick arm


14


W provides a cavity for a wick cylinder


16


C to be installed into, so as to maintain the lumen of wick cylinder


16


C in a vertical orientation. Wick


16


is installed into the lumen of wick cylinder


16


C and held in position by a small amount of glue (not shown). Wick


16


and wick cylinder


16


C comprise a single replaceable unit. Wick arm


14


W is bent as needed to position the encircled wick cylinder


16


C and enclosed wick


16


in a proper relation to a drip diffuser


18


. In the proper relation, wick tip


16


T is eight millimeters away from, and level with the nearest point on the equator of diffuser


18


. However, a keeper can consist of any suitable material, formed in such a manner as to position the fiberglass wick and drip diffuser in an appropriate position. Additionally, a keeper can be manufactured as an integral or adjustable component, contained within a single unit, which would include a wax candle, a wax reservoir support and a wax reservoir therein.

, is composed of fine fiberglass strands and is installed in a wick cylinder


16


C. Wick cylinder


16


C is a tiny glass cylinder that is 26 millimeters long, seven millimeters in diameter, with a lumen that is three millimeters wide. In the preferred embodiment, wick


16


is fifteen millimeters long and three millimeters in diameter. However, the wick can be constructed instead from any suitable non-combustible material, with a variety of dimensions, and capable of performing the traditional functions of a candlewick. Additionally, a candlewick can be manufactured as an integral or adjustable component, contained within a single unit, which would include a wax candle, a wax reservoir support and a wax reservoir therein.




A drip diffuser


18


positioned to receive drops of molten wax as they fall from a wax reservoir


30


. In the preferred embodiment, diffuser


18


is a glass sphere being twenty-five millimeters in diameter. Diffuser


18


rests on drip diffuser cradle


14


T, and is held in position by gravity. However, the drip diffuser can be constructed from any other suitable material such as stone, ceramic, steel, etc. And can be shaped in any other suitable configuration such as oval, teardrop, barrel convoluted, etc. Additionally, a drip diffuser can be manufactured as an integral or adjustable component, contained within a single unit, which would include a wax candle, a wax reservoir support and a wax reservoir therein. Additionally, a drip diffuser can be configured in such a manner as to produce a pleasant sound as molten wax drips onto it's surface.




My Candle has a Wax Reservoir Support


20


Consisting of:




Four plate glass panels having a thickness of six millimeters and a length of nineteen centimeters. Front panels


22


FL and


22


FR are six centimeters wide, while rear panels


22


RL and


22


RR are seventeen centimeters wide. In the preferred embodiment, the panels are attached with panel connectors


26


in the following sequence; a front left panel


22


FL attaches on its rear side to the front side of a rear left panel


22


RL, which attaches on its back side to the back side of a rear right panel


22


RR, which attaches on its front side to the back side of a front right panel


22


FR. This connection sequence forms a hollow, four-sided glass column. The front left panel and the front right panel do not connect to each other, creating a five centimeter gap that extends from the bottom to the top of support


20


. This gap allows access to wick


16


for lighting and extinguishing. Perched on top of support


20


, and held in place by gravity, is a wax reservoir


30


. However, a wax reservoir support can be constructed from any other suitable material such as plastic, stone, mirrors, ceramic, steel, etc. And can be shaped in any other suitable configuration such as oval, circular, perforated etc. Additionally, a wax reservoir support can be manufactured as an integral or adjustable component, contained within a single unit, which would include a wax candle, a wax reservoir support and a wax reservoir therein. Also, a wax reservoir support can be constructed with a configuration that baffles air circulation around the candle, thus allowing the candle to function in a breezy environment. Mirrored surfaces can be incorporated into the reservoir support as well.




My Candle has a Wax Reservoir


30


Consisting of:




A wax reservoir container


32


that contains a reservoir wax


34


. In the preferred embodiment, wax reservoir container


32


is a separate unit composed of tin, available from Atlantic Sales & Distribution, INC. of Burlington, N.J. Reservoir container


32


is nine centimeters wide, by nine centimeters long, by ten centimeters high. A reservoir wax exit


32


E is provided on the bottom of reservoir container


32


which allows molten wax to egress and drip down from a drip release point


32


R during operation to candle


10


below. Wax exit


32


E is formed by a linear series of perforations in the bottom of reservoir container


32


. These perforations are located bet ween the center on the bottom of reservoir container


32


and a drip release point


32


R. Drip release point


32


R is located on the lowest corner of the bottom of reservoir container


32


as it sits installed on top of support


20


. Within reservoir container


32


is space provided for storage of reservoir wax


34


that is gradually consumed during the operation of my candle. This storage space can be accessed by operating a wax reservoir container lid


32


L thus allowing the user to replenish the enclosed supply of reservoir wax


34


. However, a wax reservoir container can consist of any suitable material such as glass, ceramic, stone, etc. Additionally, a wax reservoir container can be manufactured as an integral or adjustable component, contained within a single unit, which would include a wax candle, a wax reservoir support and a wax reservoir therein.




From the description above, a number of advantages of my candle become evident:




(a) A single candle can be used to burn an infinite number of wax types with different types, colors and scents.




(b) When using my candle there is never any unused wax to be discarded.




(c) Containment is provided for all molten wax keeping it from escaping into the surrounding environment.




(d) Safety features include flame shielding, automatic flame-size control, and a self-extinguishing wick.




(e) My candle will burn longer than any other wax candle.

The manner of operating the eternal candle can be divided into three categories; setup, enjoyment and maintenance. After initial setup of the preferred embodiment, the candle does not need to be setup again between uses unless maintenance is needed. However, an embodiment comprised of a single unit containing a wax candle, a wax reservoir support and a wax reservoir, would eliminate the need for setup at any time.




Setup of the preferred embodiment involves lighting wick


16


and subsequently positioning the three main components, candle


10


, support


20


and reservoir


30


in proper relation to each other (FIG.


2


). Wick


16


can be lit in the same manner as a traditional wax candle with a match, butane lighter, burning candle, etc. The burning candle


10


is positioned in an appropriate location with diffuser


18


positioned behind wick


16


(FIG.


2


). Reservoir support


20


is then positioned over candle


10


with the vertical opening of support


20


facing forward (FIG.


2


). Reservoir


30


is then perched on the cornice of support


20


(FIG.


2


). When so perched, reservoir


30


must have reservoir wax exit


32


E facing forward (FIG.


2


). Drip release point


32


R must be the lowest point on reservoir


30


(FIG.


2


). Also, drip release point


32


R must be positioned directly above diffuser


18


(FIG.


2


). In this configuration the eternal candle will enter a perpetual burning cycle, during which it can be enjoyed as any other traditional candle.




Enjoyment of the eternal candle includes but is not limited to; soft candle light, observing rhythmic dripping of molten wax onto a clear glass marble, the aroma of any scent added to reservoir wax, etc. While the user is enjoying the eternal candle, the candle is maintaining a steady flame as a result of the candles subtle burning cycle. The burning cycle will self sufficiently continue until the flame is exposed to a heavy breeze, the flame is extinguished, or the wax supply in reservoir


30


is depleted. During the burning cycle, candle


10


will be in on e of three phases (

FIGS. 3A

,


3


B and


3


C). The low phase (

FIG. 3C

) is entered into as a result of slightly more wax being burned on wick


16


than is being replenished by reservoir


30


. This condition causes more of the surface area of wick


16


to be exposed above the molten surface of candle wax


13


. With a greater surface area exposed on wick


16


, the flame size of candle


10


increases. As the flame size of candle


10


increases, its heat output increases and the temperature of reservoir


30


above increases as well. As the temperature of reservoir


30


increases, the melting rate of reservoir wax


34


increases inside of reservoir


30


. This increase in the melting rate of reservoir wax


34


causes more molten reservoir wax


34


to flow out through reservoir wax exit


32


E (

FIGS. 1

,


2


,


4


), and drip from drip release point


32


R (

FIGS. 1

,


2


,


4


). As more wax drips down into candle


10


, the level of molten candle wax


13


in candle


10


rises. A rising level of molten candle wax


13


in candle


10


causes the candle to enter the high phase (FIG.


3


A). A higher level of molten candle wax


13


causes less surface area on wick


16


to be exposed above the surface of molten candle wax


13


. Consequently, with less surface area exposed on wick


16


above the molten surface of candle wax


13


, the flame size of candle


10


decreases. As the flame size of candle


10


decreases, its heat output decreases, and the temperature of reservoir


30


above decreases as well. As the temperature of reservoir


30


decreases, the melting rate of reservoir wax


34


decreases inside of wax reservoir


30


. This decrease in the melting rate of reservoir wax


34


causes less molten reservoir wax


34


to flow out through reservoir wax exit


32


E (

FIGS. 1

,


2


,


4


), and drip from drip release point


32


R (

FIGS. 1

,


2


,


4


). As less wax drips down into candle


10


, the level of molten candle wax


13


in candle


10


falls slightly. A falling level of molten candle wax


13


in candle


10


causes the candle to enter the low phase (FIG.


3


C). As the eternal candle fluctuates slowly between the high phase (

FIG. 3A

) and the low phase (FIG.


3


C), it enters a balanced phase (

FIG. 3B

) for a period of time. The length of time that the candle stays in a balanced phase depends on how stabilized the influencing factors are. These influencing factors include but are not limited to; air temperature around the candle, air movement around the candle, distance between drip release point


32


R and drip diffuser


18


, melting point of wax being used, amount of wax in wax reservoir


30


, etc.




Maintenance of the eternal candle is required when; reservoir wax


34


needs replenished (approximately every 50 hours of use), reservoir wax


34


is allowed to run out during use, wick


16


develops carbon deposits on wick tip


16


T, diffuser


18


becomes scorched. Reservoir wax


34


is replenished by simply lifting reservoir


30


off of support


20


, removing a wax reservoir container lid


32


L from reservoir container


32


, placing candle wax (solid) inside reservoir container


32


, replacing wax reservoir container lid


32


L on reservoir container


32


, and replacing reservoir


30


on reservoir support


20


. If reservoir wax is allowed to run out during use, then the following steps must be taken to prepare candle for future use; reservoir wax must be replenished as outlined above, soot deposits left as a result of continuous high flame can be cleaned up with vinegar, level of candle wax


13


must be raised above the top of the wick cylinder


16


C by manually placing wax into candle


10


(small pieces of solid wax can be used), and wick


16


must have a few drops of molten wax (from another candle) dripped onto it. If wick


16


develops large carbon deposits on wick tip


16


T, then wick


16


can be replaced as follows; candle


10


can be positioned on an electric heating surface (such as a coffee maker) and allowed to warm up until all candle wax


13


within candle container


12


is in the molten state, then wick


16


can be removed (with wick cylinder


16


C attached) from wick arm


14


W by grasping the wick


16


and lifting straight up while candle wax


13


is still molten. A replacement wick (wick


16


and attached wick cylinder


16


C) can be lowered into the wick arm


14


W and the wax candle should then be allowed to cool (until all candle wax


13


solidifies) before moving. If diffuser


18


becomes scorched simply allow candle to cool, pry drip diffuser


18


out of candle wax


13


, and clean scorch marks with vinegar.




Summary, Ramifications, and Scope




Accordingly, the reader will see that the Eternal Candle can be used and enjoyed as any traditional candle can be. Beyond all the usual benefits of a traditional candle, the Eternal Candle offers safety features such as:




A short wick length that will keep the flame size small and safe at all times.




A wick designed that will extinguish it's own flame if the reservoir discharges too much wax or is allowed to run dry during operation.




A glass column that surrounds the candle and forms a physical barrier against flammable material that might otherwise accidentally come in contact with the candle's flame




Non-flammable containment for all wax (In either a solid or molten state) that will prevent wax from entering the surrounding environment.




Additionally, the Eternal Candle provides the user with the opportunity to control (and alter if desired) the type of wax being dispensed by the reservoir and subsequently burned by the candle. Such control enables a user to exercise such options as




Recycling the burned out shell of a traditional candle by placing it in the reservoir and allowing it to melt into, and be used by, the candle below.




Using scented wax in the reservoir for enjoying an unlimited variety of aromas.




Using colored wax in the reservoir for enjoying an unlimited variety of colors.




Create and enjoy personal blends of wax aroma and wax color without having to actually construct a complete and functional candle.




Although the description above contains multiple specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, the candle can be constructed from one piece of material rather than three separate parts. Also, the column surrounding the candle can be constructed so as to protect the rising column of heated air above the flame from drafts with complete enclosure and baffled ventilation.




Thus the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.



Claims
