- the spill guard 40 is press-fit into the open, second end of the receiving container 12 opposite the plug 22 .
- the spill guard 40 is connected to the side wall portion 21 adjacent the open end of the receiving chamber, opposite and spaced apart from the plug 22 .
- the spill guard 40 is a generally frustoconically-shaped piece having a large peripheral flange 42 extending from a wide-end of the frustoconically-shaped piece and a small flange 44 extending from the small or narrow-end of the frustoconically-shaped piece of the spill guard 40 .
- the small flange 44 surrounds a generally centrally located aperture 46 that receives and supports the wick 14 therethrough. More specifically, the aperture 46 is sized to snugly receive the wick 14 thereby preventing fluid from being able to escape the receiving chamber through the open end without passing through the wick 14 .
- the tapered surface of the frustoconical spill guard 40 facilitates the filling of the chamber 24 .
- the lid 20 and wick 14 are removed.
- a flammable liquid or fuel is poured into the fluid receiving chamber 24 through the aperture 46 of the spill guard 40 .
- the lid 20 is replaced with the wick 14 extending into the fuel for absorption thereof.
- the wick 14 can then be lit and will burn until substantially all the fuel is absorbed by the wick 14 and burned.
- the spill guard 40 acts to prevent fuel leakage if the torch 10 is positioned in a horizontal orientation such as might happen if the torch 10 , and specifically, the receiving container 12 , is accidentally knocked over. More specifically, the combination of the wick 14 and the spill guard 40 serves as a barrier to trap the fuel within the receiving container 12 . If the wick 14 is not in place and the torch 10 is knocked over, the spill guard 40 still serves a mitigating function. The spill guard 40 will reduce the rate of fuel exiting or evacuating from the receiving container 12 . That is, the aperture 46 is smaller than the diameter of the receiving container 12 so less fuel can escape from the receiving container 12 over a given period of time. Also, the spill guard 40 limits the amount of fuel that escapes after an accidental knock over. A portion of the fuel will remain trapped in the receiving container 12 because the centrally located aperture 46 of the spill guard 40 is radially offset relative to the interior walls of the receiving container 12 .

- the elongated member 16 can be a length of copper pipe and the reducer 18 can be a conventional-type reducer sized to connect the elongated member 16 to the receiving container 12 .
- the connection between the reducer 18 and the receiving container 12 is intentionally unsoldered and made without adhesives or the like. This removable connection allows the receiving container 12 to be removed from the elongated member 16 and transported to a convenient location for refilling with fuel.
- alternate embodiments could be made wherein the receiving container 12 is permanently secured to the support member 18 .
- the torch 10 includes a bushing or wick holder 50 positioned within a small aperture 52 of a lid 54 .
- a shoulder 56 of the lid 54 supports the wick holder 50 .
- the wick holder 50 includes a wick opening 58 adjacent an upper end of the wick holder 50 and having a diameter substantially similar to a diameter of the wick 14 for receiving and holding the wick 14 .
- Bored into a first end 60 of the wick holder, the end that is resting on the shoulder 56 of the lid 54 is an aperture or countersink having a tapered surface 62 connected to the wick opening 58 . More specifically, a throughhole communicates the wick opening 58 to the countersink.
- the tapered surface 62 facilitates insertion of the wick 14 into the throughhole of the wick holder 50 .
- the tapered surface 62 guides a portion of the wick 14 into and through the throughhole.
- the first end 60 forms a radial annular surface 64 .
- the thickness of the radial annular surface 64 is such that a droplet of fuel is capable of forming thereon. More specifically, as fuel wicks up through the wick 14 to be burned, a portion of the unburned fuel transfers to the element or piece that holds the wick 14 , in this embodiment the wick holder 50 . More specifically, the unburned fuel transfers to the tapered surface 62 and to the annular surface 64 . In some prior art torches, such as those not utilizing a wick holder 50 , fuel would transfer directly to the lid and can flow down the lid to the outside of the receiving container 12 . Such fuel flow is, of course, undesirable because this fuel would no longer be contained by the torch. In the present invention, the annular surface 64 of the wick holder 50 permits the fuel to form droplets thereon and drip back into the receiving container 12 , as opposed to transferring to the lid and flowing down the outside of the receiving container.
- the torch device 10 may be constructed from standard copper plumbing pipe and associated copper fittings.
- the torch device 10 when constructed of copper plumbing pipe material, results in a strong, virtually permanent fixture that will weather and age to yield a copper green patina, or may be coated with a clear covering to maintain its original shiny copper finish.
- the fixture material can be painted or otherwise colored into any other color, such as green, black, brown, or yellow.

Description
- This application claims the benefit of and hereby expressly incorporates by reference U.S. Provisional Patent Application Ser. No. 60/306,016, filed on Jul. 17, 2001.
- 1. Field of the Invention
- The present invention relates to a decorative torch, and more particularly, to an improved torch device for use as an aesthetically pleasing decoration in a garden, on or near an outdoor deck, or on a tabletop and/or for use as a lighting source, and will be described with particular reference thereto. However, it will be appreciated that the present invention is also amenable to other like applications.
- 2. Discussion of the Art
- Torch devices are well known and have been very successful commercially. In general, torch devices include a receiving container for storing flammable fuel such as lamp oil, kerosene, or the like and a wick for burning a controlled amount of the flammable fuel. A pole or other elongated holding device may be used to elevate the receiving container to a desired height and a wick-holder assembly may be used to maintain the wick in a desired position within the receiving container.
- The receiving container is often a cylindrical pipe-like piece closed at one end by a cap or plug. In known torch devices, the cap or plug is often press-fit onto one end of the cylindrical piece. One of the problems encountered with such a press-fit connection is leakage of the flammable fluid between the cylindrical piece and the cap or plug. There are many reasons why such a leak may occur. For example, the dimensions of the cylindrical piece and/or the cap or plug may not be within tolerance leaving a gap therebetween upon connection. Thus, there is a need for a torch device having a leak-proof receiving container.
- Another problem with prior art torch devices is that when accidentally knocked over the flammable fluid of the receiving container spills out. The rate of the spill and the amount of the spill are uncontrolled. Thus, the result of a spill is a quick and complete evacuation of the flammable fluid from the receiving container. There is a need for a torch device that reduces or eliminates the rate of spillage flow of flammable fluid when the torch device is knocked over. Also, there is a need for a torch device that eliminates or reduces the amount of flammable fluid capable of exiting the receiving container when the torch device is accidentally knocked over.
- Yet another problem with known torch devices is that wicking flammable oil leaks from the wick-holder assembly during operation of these torch devices. More particularly, wicking flammable fluid transfers away from the wick to the wick-holder assembly. From the wick-holder assembly, the wicked flammable fluid drains down the outside of the receiving container. Of course, it is undesirable to have flammable fluid dripping down the outside of the receiving container and, therefore, there is a need for a torch device that prevents such undesirable dripping.
- The present invention provides an improved torch device for minimizing the above-referenced and other disadvantages of the prior art.
- In accordance with one aspect of the present invention, a new and improved torch device is provided. More particularly, in accordance with this aspect of the invention, the torch device includes an elongated member and a support member attached adjacent one end of the elongated member. A receiving container is connected to the elongated member by the support member. The receiving container includes a side wall portion and a base portion connected to the side wall portion and defining a receiving chamber within the side wall portion for holding an associated fluid. The receiving container further includes a seal between the side wall portion and the base wall portion for preventing the associated fluid from escaping the receiving chamber by passing between the side wall portion and the base wall portion. A wick is partially received within the receiving chamber and partially extends outward therefrom.
- According to another aspect of the present invention, a fluid receiving container for use with an associated torch apparatus is provided. More particularly, in accordance with this aspect of the invention, the container includes a tubular body portion and a plug for closing one end of the tubular body portion thereby defining a fluid receiving cavity with an open end opposite the plug. A membrane for impermeably sealing between the fluid receiving cavity and the plug is positioned adjacent the plug.
- According to still another aspect of the present invention, a fluid receiving container for use with an associated torch apparatus is provided. More particularly, is accordance with this aspect of the invention, the container includes a side wall portion and a base portion connected to the side wall portion. The base portion and the side wall portion together define a receiving chamber having an open end spaced apart from the base portion. A lid is connected to the side wall portion to close the open end of the receiving chamber. The lid includes an aperture and a bushing supported in the lid aperture. The bushing includes a throughhole for allowing a wick to pass therethrough and a tapered countersink adjacent an end of the throughhole that is adjacent the receiving chamber. The countersink and an adjacent end face of the bushing cooperatively collect excess fluid contained in the wick and return said collected excess fluid to the receiving chamber.
- According to yet another aspect of the present invention, a new and improved method of constructing a torch device is provided. More particularly, in accordance with this aspect of the invention, the method includes the step of providing an elongated member. A support member is connected to one end of the elongated member. A receiving container is constructed including the sub-steps of providing a tubular portion. A plug is pressed into one end of the tubular portion to create a cup-shaped housing that defines a cavity having an open, upper end spaced apart from the plug. A liquid adhesive is applied to the plug in the cavity such that after curing it will form a sealing membrane between the cavity and the plug. The constructed receiving container is seated in a seating cavity of the support member. A wick is positioned in the receiving container cavity and is allowed to protrude therefrom.
- One advantage of the present invention is that it prevents fuel leakage from an underside of the torch device.
- Another advantage of the present invention is that it reduces the rate of fuel leakage from a topside of the torch device should the torch device be knocked over.
- Yet another advantage of the present invention is that it reduces the amount of fuel capable of leaking from a topside of the torch device should the torch device be knocked over.
- Still yet another advantage of the present invention is that it reduces the amount of fuel that leaks down the outside of the torch device due to undesirable wicking.
- Still further advantages and benefits of the present invention will become apparent to those of ordinary skill in the art upon reading and understanding the following detailed description of the preferred embodiments.
- The structure, operation and advantages of the presently preferred embodiment of this invention will become further apparent upon consideration of the following description, taken in conjunction with the accompanying drawings. Of course, the drawings are only for purposes of illustrating preferred embodiments and are not to be construed as limiting the invention.
- FIG. 1 is a perspective view of a preferred torch device in accordance with the present invention.
- FIG. 2 is a partial cross-sectional view of the preferred torch device shown in FIG. 1 showing a cap-supported membrane and a spill guard.
- FIG. 3 is a cross-sectional view of another preferred torch device in accordance with the present invention showing a wick holder.
- With reference to FIG. 1, an improved torch device is generally shown by
reference numeral 10. The improved torch device orapparatus 10 comprises a cylindrical receivingcontainer 12, awick 14, and anelongated member 16. The receivingcontainer 12 is connected to theelongated member 16 by an appropriately sizedfirst reducer 18, also referred to herein as a support member. Thesupport member 18 is attached to theelongated member 16 adjacent one end of theelongated member 16. The receivingcontainer 12 is selectively detachable from theelongated member 16, in the preferred embodiment, by a removable connection between thesupport member 18 and the receivingcontainer 12 as will be described in more detail below. Thewick 14 is held in an axial center of the receivingcontainer 12 by a second reducer orlid 20. - With reference to FIG. 2, the receiving
container 12 includes a side wall orbody portion 21 and a cap or plug 22 positioned at one end of theside wall portion 21 to form a fluid-receiving chamber 24. More specifically, the base portion or plug 22 is connected to theside wall portion 21 closing one end of theside wall portion 21 while leaving a second end (opposite the plug) of theside wall portion 21 open thereby defining the cup-like cavity or chamber 24 adapted to hold an associated fluid fuel. Thewick 14 is partially received within the chamber 24 and partially extends outward from the chamber 24. Theside wall portion 21 may be a tubular member such as a section of copper tubing or any other suitable material. Theplug 22 is press-fit into the one end of theside wall portion 21 as illustrated. Theplug 22 may be constructed of any material, copper in an exemplary embodiment, that is not detrimentally reactive with theside wall portion 21. - The
plug 22 is generally cup-shaped and includes a generallyplanar section 30 and an integrally formed peripheral side wall orannular skirt 26 extending around the circumference of theplug 22 and depending from theplanar section 30 for engaging aninterior side 28 of the receivingcontainer 12. More specifically, thecircumferential side wall 26 is sized such that it will seat firmly within the receivingcontainer 12 abutting theside wall portion 21 without deforming the outside diameter of the receivingcontainer 12, i.e., theside wall 26 has an outer diameter that substantially matches an inner diameter of theside wall portion 21 of the receivingcontainer 12. The planar section orsupport wall 30 is oriented approximately normal to a longitudinal axis of the receivingcontainer 12 and forms a base of the fluid receiving chamber 24. A rounded surface orouter radius 32 connects theside wall 26 and thesupport wall 30. Thus, theouter radius 32 is formed at the intersection of theside wall 26 and theplanar surface 30. Theouter radius 32 and theside wall portion 21 of the receivingcontainer 12 together form a retainingpocket 33. In the embodiment shown, theplug 22 is positioned adjacent one end of theside wall portion 21. However, theplug 22 can be positioned at any location along the length of theside wall portion 21 spaced apart from the open end to define various sized receiving chambers. - The second reducer or
lid 20 is removably secured to the open end of the receivingcontainer 12. More particularly, thelid 20 includes alarge aperture section 34 at a first end for fitting around the outside diameter of the receivingcontainer 12. Thelid 20 also includes asmall aperture section 36 at the other, second end for receiving and securing thewick 14. Thelid 20 can be a conventional pipe reducer sized to appropriately connect to the receivingcontainer 12 at one end and to snugly receive thewick 14 at the other end. Alternatively, two or more pipe reducers connected in series can be used to form thelid 20. Of course, other lid designs are contemplated and all such designs are to be considered within the scope of the present invention. - The
wick 14 is inserted in a small aperture defined by thesmall aperture section 36 of thelid 20 and extends into the receivingcontainer 12 along or generally near an axial center of the receivingcontainer 12. In the preferred embodiment, theplug 22 is positioned within the receivingcontainer 12 such that thewick 14 extends nearly to theplug 22. Thus, thewick 14 is partially received within the chamber 24 and partially extends outward from the chamber 24 through thelid 20. - In prior art devices, the aforementioned assembly completed the primary structural components of the
torch 10. Thelid 20 andwick 14 were removed to gain access to the fuel receiving chamber 24. A liquid fuel was poured into the receivingcontainer 12 to occupy at least a portion of the fluid receiving chamber 24. The press-fit connection between theplug 22 and the receivingcontainer 12 was relied upon to prevent the fuel from escaping out the bottom of thetorch 10. Unfortunately, the press-fit connection was not always reliable and often did not prevent the fuel from escaping the receiving chamber 24 by passing between theside wall portion 21 and theplug 22. - The
improved torch 10 of the present invention additionally includes a means for sealing the connection between theside wall portion 21 and theplug 22. In the illustrated embodiment, the means for sealing is a seal such as membrane 38. The membrane 38 is positioned within the fluid receiving chamber 24 at the base of the fluid receiving chamber 24 (adjacent the plug 22) and forms a fluid impermeable seal between theplug 22 and theside wall portion 21. Thus, the membrane 38 seals between theside wall portion 21 and theplanar section 30 to prevent fluid held in the chamber 24 from escaping therefrom by passing between theside wall portion 21 and theplanar surface 30. The membrane 38 adheres or bonds to the interior orinner wall 28 of the receivingcontainer side wall 21, thesupport wall 30 and therounded surface 32 of theplug 22. Further, the membrane 38 fills the retainingpocket 33. The membrane or diaphragm 38 extends across the entire cross-section of theside wall 21 to form a barrier or impermeable wall between the chamber 24 and the base wall portion orplanar surface 30 of theplug 22. Additionally, the membrane 38 is supported on and rests against thesupport wall 30 of theplug 22 when the receivingcontainer 12 is vertically oriented with its open end positioned upward. - The membrane38 is added to the
torch 10 after theplug 22 is press-fit into the receivingcontainer 12. More specifically, the membrane 38, in a liquid, pre-applied form, is injected into the receivingcontainer 12 by means of a syringe or the like. The membrane 38 is then allowed to cure or dry. While drying, the membrane 38 expands to snugly fill the space between therounded surface 32 and theinterior wall 28. After drying, the membrane 38 has become a hardened membrane seal that adheres or bonds to the receivingcontainer 12 and theplug 22 thereby creating a seal therebetween. - In the preferred embodiment, the membrane38 is formed from POR-15 RUST PREVENTATIVE PAINT available from RestoMotive Laboratories, Inc. of Morristown, N.J. However, other suitable materials can be substituted that maintain similar adhesive/bonding and sealing qualities.
- Another improvement to the
torch 10 of the present invention is the inclusion of the aspill guard 40. Thespill guard 40 is press-fit into the open, second end of the receivingcontainer 12 opposite theplug 22. Thus, thespill guard 40 is connected to theside wall portion 21 adjacent the open end of the receiving chamber, opposite and spaced apart from theplug 22. Thespill guard 40 is a generally frustoconically-shaped piece having a large peripheral flange 42 extending from a wide-end of the frustoconically-shaped piece and a small flange 44 extending from the small or narrow-end of the frustoconically-shaped piece of thespill guard 40. The small flange 44 surrounds a generally centrally locatedaperture 46 that receives and supports thewick 14 therethrough. More specifically, theaperture 46 is sized to snugly receive thewick 14 thereby preventing fluid from being able to escape the receiving chamber through the open end without passing through thewick 14. The tapered surface of thefrustoconical spill guard 40 facilitates the filling of the chamber 24. - To prepare the
torch 10 for use with the membrane 38 in place, thelid 20 andwick 14 are removed. A flammable liquid or fuel is poured into the fluid receiving chamber 24 through theaperture 46 of thespill guard 40. Upon filling a portion of the chamber 24 with fuel, thelid 20 is replaced with thewick 14 extending into the fuel for absorption thereof. Thewick 14 can then be lit and will burn until substantially all the fuel is absorbed by thewick 14 and burned. - The
spill guard 40 acts to prevent fuel leakage if thetorch 10 is positioned in a horizontal orientation such as might happen if thetorch 10, and specifically, the receivingcontainer 12, is accidentally knocked over. More specifically, the combination of thewick 14 and thespill guard 40 serves as a barrier to trap the fuel within the receivingcontainer 12. If thewick 14 is not in place and thetorch 10 is knocked over, thespill guard 40 still serves a mitigating function. Thespill guard 40 will reduce the rate of fuel exiting or evacuating from the receivingcontainer 12. That is, theaperture 46 is smaller than the diameter of the receivingcontainer 12 so less fuel can escape from the receivingcontainer 12 over a given period of time. Also, thespill guard 40 limits the amount of fuel that escapes after an accidental knock over. A portion of the fuel will remain trapped in the receivingcontainer 12 because the centrally locatedaperture 46 of thespill guard 40 is radially offset relative to the interior walls of the receivingcontainer 12. - With reference back to FIG. 1, the
elongated member 16 is connected to the receivingcontainer 12 by the appropriatelysized reducer 18. Theelongated member 16 can be a length of copper pipe and thereducer 18 can be a conventional-type reducer sized to connect theelongated member 16 to the receivingcontainer 12. The connection between thereducer 18 and the receivingcontainer 12 is intentionally unsoldered and made without adhesives or the like. This removable connection allows the receivingcontainer 12 to be removed from theelongated member 16 and transported to a convenient location for refilling with fuel. However, it is contemplated that alternate embodiments could be made wherein the receivingcontainer 12 is permanently secured to thesupport member 18. - With reference to FIG. 3, in an alternate embodiment, the
torch 10 includes a bushing orwick holder 50 positioned within asmall aperture 52 of alid 54. Ashoulder 56 of thelid 54 supports thewick holder 50. Thewick holder 50 includes awick opening 58 adjacent an upper end of thewick holder 50 and having a diameter substantially similar to a diameter of thewick 14 for receiving and holding thewick 14. Bored into afirst end 60 of the wick holder, the end that is resting on theshoulder 56 of thelid 54, is an aperture or countersink having a taperedsurface 62 connected to thewick opening 58. More specifically, a throughhole communicates the wick opening 58 to the countersink. The taperedsurface 62 facilitates insertion of thewick 14 into the throughhole of thewick holder 50. Thus, when thewick 14 is forced into thewick holder 50, the taperedsurface 62 guides a portion of thewick 14 into and through the throughhole. Surrounding the taperedsurface 62, thefirst end 60 forms a radial annular surface 64. - Of particular importance, the thickness of the radial annular surface64 is such that a droplet of fuel is capable of forming thereon. More specifically, as fuel wicks up through the
wick 14 to be burned, a portion of the unburned fuel transfers to the element or piece that holds thewick 14, in this embodiment thewick holder 50. More specifically, the unburned fuel transfers to the taperedsurface 62 and to the annular surface 64. In some prior art torches, such as those not utilizing awick holder 50, fuel would transfer directly to the lid and can flow down the lid to the outside of the receivingcontainer 12. Such fuel flow is, of course, undesirable because this fuel would no longer be contained by the torch. In the present invention, the annular surface 64 of thewick holder 50 permits the fuel to form droplets thereon and drip back into the receivingcontainer 12, as opposed to transferring to the lid and flowing down the outside of the receiving container. - Many components of the
torch device 10, in all the aforementioned embodiments, may be constructed from standard copper plumbing pipe and associated copper fittings. Thetorch device 10, when constructed of copper plumbing pipe material, results in a strong, virtually permanent fixture that will weather and age to yield a copper green patina, or may be coated with a clear covering to maintain its original shiny copper finish. Alternatively, the fixture material can be painted or otherwise colored into any other color, such as green, black, brown, or yellow. - The invention has been described with reference to the preferred embodiments. Obviously, modifications and alterations will occur to others upon reading and understanding the preceding detailed description. It is intended that the invention be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
