The bore has an air-entrance end and a heat-resistant air-exit end. A flexible tubular member, that is bendable at one or more points along a length thereof, has a bore extending therethrough. The bore of the flexible tubular member has an air-entrance end into which the individual can blow air and an air-exit end. The air-exit end of the bore of the flexible tubular member is coupled to the air-entrance end of the bore of the rigid tubular member. The coupled bores together define a passageway for directing the air blown by the individual into the air-entrance end of the flexible tubular member to the heat-resistant air-exit end of the rigid tubular member.
Description
- The invention relates generally to blowpipes for directing blown air into a fire.
- A well-known principle of inflaming a fire is to blow air over its hot embers. The blown air concentrates and increases the heat so that the nearby fuel ignites into flame. For this purpose, people have devised various tools for blowing directed air. One type of such tool, referred to as a bellows, mechanically draws in air through a valve and expels air through a tube by alternately expanding and contracting. Another type relies upon the force of breath. Tools of this type include long, straight cylindrical tubes or pipes. In general, a user blows into one end of the tube and the blown air exits a hole at the opposite end.
- The effectiveness of these tubes to inflame the fire depends upon the user's ability to deliver the air flow to a hot spot. Usually, such hot spots are among the embers at the base of the fire, for example, below a fireplace grill or behind other burning logs. Long straight tubes, however, offer little flexibility as to where the user may stand with respect to the fire when operating the tool. To bring the end hole of the straight tube into proximity of the glowing embers and then to blow into it, the user may need to stand or crouch awkwardly. As a result, the user may be uncomfortably close to the heat of the fire or too far removed from the fire to produce an effective jet of air. There is, therefore, a need for a tool for inflaming fires that users can operate conveniently and within comfortable distance of the fire.
- In one aspect, the invention features a tool for directing blown air at a fire. The tool includes a rigid tubular member having a bore extending therethrough. The bore of the rigid tubular member has an air-entrance end and a heat-resistant air-exit end. A flexible tubular member that is bendable at one or more points along a length thereof has a bore extending therethrough. The bore of the flexible tubular member has an air-entrance end into which the individual can blow air and an air-exit end. The air-exit end of the bore of the flexible tubular member is coupled to the air-entrance end of the bore of the rigid tubular member. Together the coupled bores define a passageway for directing the air blown into the air-entrance end of the flexible tubular member by the individual to the heat-resistant air-exit end of the rigid tubular member.
- In another aspect, the invention features an apparatus for use by an individual to blow air at a fire. The apparatus includes rigid means for providing a first air passageway having an air-entrance end and a heat-resistant air-exit end, and bendable means for providing a second air passageway having an air-entrance end into which the individual can blow air and an air-exit end. The bendable means is bendable at one or more points along a length thereof. The air-exit end of the second air passageway is coupled to the air-entrance end of the first air passageway. Together the coupled first and second air passageways provide a combined air passageway for directing air blown by the individual into the air-entrance end of the second air passageway to the air-exit end of the first air passageway.
- The above and further advantages of this invention may be better understood by referring to the following description in conjunction with the accompanying drawings, in which like numerals indicate like structural elements and features in various figures. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention.

FIG. 1 shows an embodiment of afire persuader 2 constructed in accordance with the principles of the invention. Thefire persuader 2 includes aflexible portion 4 and arigid portion 6. Theflexible portion 4 includes amouthpiece 8, through which the individual can blow air into thefire persuader 2, and a bendabletubular member 10. The bendabletubular member 10 has a bore extending therethrough. The bore has an air-entrance end and an air-exit end. Themouthpiece 8 is coupled to the air-entrance end of the bendabletubular member 10. As shown, the bendabletubular member 10 can bend at one or more points along a length thereof. In a preferred embodiment, thebendable member 10 retains the shape into which it has been bent. In another embodiment, thebendable member 10 is resilient, and returns to a substantially straight shape when the bending force is removed. - The
rigid portion 6 includes an elongate, straight, cylindrical, rigidtubular member 12 and acoupling device 14. The rigidtubular member 12 also has a bore extending therethrough, with an air-entrance end and a heat-resistant air-exit end 16. Thecoupling device 14 joins the air-exit end of the bendabletubular member 10 to the air-entrance end of the rigidtubular member 12. Thetubular members mouthpiece 8. This passageway extends from the air-entrance end of the bendabletubular member 10 to the heat-resistant air-exit end 16 of the rigidtubular member 12. Air blown into themouthpiece 8 passes through the bendable and rigidtubular members exit end 16 of the rigidtubular member 12. Also, thecoupling device 14 provides a locus at which to hold thefire persuader 2 for directing the air-exit end 16 towards certain significant places in the fire. The individual can, by holding therigid tubular member 12 near thecoupling device 14, use therigid portion 6 as a poker to stoke the fire. - In one embodiment, the bendable tubular member 10 (when straightened) is 24 inches in length and the
rigid tubular member 12 is 20 inches in length. Such lengths enable the individual to rekindle the fire at a comfortable distance from the fire's heat. Fire persuaders of other lengths can be constructed without departing from the principles of the invention. -
FIG. 2 shows a side view of the air-entrance end of therigid tubular member 12 being joined to the air-exit end of thebendable tubular member 10 by thecoupling device 14. Thebendable tubular member 10 includes a flexibleinner tube 20 and asleeve 22. Thetube 20 can be opaque or clear, and made of natural or synthetic rubber, elastomer, plastic, or any bendable material. Flexible tubes of varying resistance to heat can be used to practice the invention. In one embodiment, thetube 20 has aninner diameter 24 of ¼ inch (6.35 mm) and an outer diameter of ⅜ inch (9.525 mm). - The
sleeve 22 can be made of a synthetic rubber, e.g., neoprene and polychloroprene, or any other material that can effectively insulate and protect thetube 20 from the heat of the fire and possible puncture during use. Depending upon its type of material, thesleeve 22 can also provide structure for retaining the shape into which thebendable tubular member 10 is bent. Other embodiments of thefire persuader 2 do not employ thesleeve 22, in particular, those embodiments in which theinner tube 20 has sufficient heat-resistant characteristics. InFIG. 2 , thesleeve 22 only partially encloses theinner tube 20 and leaves a portion of the tube's outer surface exposed. In a preferred embodiment, thesleeve 22 fully surrounds thetube 20 and extends to the air-exit end of thetube 20. - The
rigid tubular member 12 is a cylindrical pipe made of metal, e.g., stainless steel, copper, brass. Metals other than those listed and materials other than metal can be used to construct therigid member 12, provided such materials can withstand high temperatures and provide sufficient strength so therigid member 12 can be used to move and pry over logs in the fire. In one embodiment, therigid tubular member 12 is an automotive brake line. Preferably, the diameter of therigid tubular member 12 is approximately ¼ inch (6.35 mm). This particular diameter size produces a concentrated and high-pressured stream of air that is more effective for inflaming a fire than an air stream having a wider diameter. Other diameter sizes can be used without departing from the principles of the invention. At the air-exit end 16 of therigid tubular member 12 is a flared tip 40 (FIG. 4 ). In some embodiments, a tip portion of therigid tubular member 12, i.e., at the air-exit end 16, is made of or coated with a fire resistant material, whereas the remainder of therigid tubular member 12 is made of a different material (e.g., less fire resistant). - The
coupling device 14 has a cylindricalnarrow end 26 for coupling to therigid tubular member 12, and a cylindricalwide end 28 for coupling to thebendable tubular member 10. In one embodiment, thecoupling device 14 is made of metal, such as copper. The diameter of thenarrow end 26 is slightly larger than the diameter of therigid tubular member 12 so that one end of therigid tubular member 10 can be press fit into thenarrow end 26 of thecoupling device 14. In one embodiment, thenarrow end 26 has an inside diameter of approximately ¼ inch and an outside diameter of approximately ⅜ inch. In some instances, the bond between thecoupling device 14 and therigid tubular member 12 can be strengthened by the use of solder. - The diameter of the
wide end 28 of thecoupling device 14 is slightly larger than the combined thickness of the flexibleinner tube 20 and thesleeve 22 so both thetube 20 andsleeve 22 are press fit within thewide end 28. In one embodiment, thewide end 28 has an inside diameter of approximately ½ inch and an outside diameter of approximately ⅝ inches. Alternatively, of thetube 20 and thesleeve 22 only thetube 20 enters thewide end 28, while thesleeve 22 abuts or covers an edge portion of thewide end 28 of thecoupling device 14. When the bendable andrigid members coupling device 14, the bore of theflexible tube 20 abuts the bore of therigid member 12 to provide a continuous air passageway from themouthpiece 8 to the air-exit end 16 of therigid tubular member 12. - Other means for coupling the
bendable member 10 to therigid member 12 can be used to practice the invention. For example, in one embodiment a fitting referred to as a reducing union holds the bendable andrigid members - In alternate embodiments, the
coupling device 14 is optional. In such embodiments, either the diameter of therigid tubular member 12 is smaller than that of theflexible tube 20 or the diameter of theflexible tube 20 is smaller than that of therigid tubular member 12, and, accordingly, the two cylindrical tubes can be joined by closely press fitting one into the other. -
FIG. 3 shows a side view of themouthpiece 8 being joined toflexible tube 20 at the air-entrance end 29 of thebendable tubular member 10. Themouthpiece 8 can be made of a variety of materials, e.g., plastic. Other materials can be used without departing from the principles of the invention. Themouthpiece 8 is an optional, although preferred component. Without themouthpiece 8, an individual can still practice the principles of the invention without themouthpiece 8 by blowing intotube 20. - The
mouthpiece 8 has a ribbedshank 30, anedge stop 32, alip region 34, and abore 36 extending therethrough. The ribbedshank 30 enters the bore of theflexible tube 20 at the air-entrance end 29 of thebendable tubular member 10. The ribs of theshank 30 are back-angled or barbed to prevent themouthpiece 8 from retracting from thetube 20. The inside surface of theflexible tube 20 at the air-entrance end 29 may be threaded to receive the ribbedshank 30. - The
edge stop 32 determines the fullest extent of entry of theshank 30 into thetube 20. In general, the mouthpiece plugs tightly into thetube 20. When themouthpiece 8 is fully inserted into the bore, theedge stop 32 abuts the end of theflexible tube 20. Thelip region 34 has a contoured outer surface to provide a smooth feeling for the lips. - To use the
fire persuader 2, an individual can hold theflexible portion 4 just below themouthpiece 8 with one hand and hold therigid portion 6 near thecoupling device 14 with the other hand. From a desired position, the individual points the air-exit end 16 of therigid portion 6 at a desired target in the fire. In this desired position, theflexible portion 4 may be bent in one or more places. The individual then blows into themouthpiece 8. The air exits thefire persuader 2 from the air-exit end 16 in the direction of the target. To illustrate the flexibility of thefire persuader 2, consider that an individual can hold therigid portion 6 horizontally, substantially parallel and close to the floor of the fireplace, while blowing into themouthpiece 8 from a kneeling, a crouching, a sitting, and, provided theflexible portion 4 is long enough, a standing position. -
FIG. 4 shows a side view of an embodiment of the flaredtip 40 at the air-exit end 16 of therigid tubular member 12. The degree of flaring of the flaredtip 40 can be enhanced to increase the ability to catch material in the fire. As shown, the flaredtip 40 is integral to therigid tubular member 12, although other embodiments can have a flaredtip 40 as a separate element that is coupled to the air-exit end 16. A curved surface or an edge of the flaredtip 40 can catch onto a log better than a flat or flush air-exit end when poking and pulling the log in the fire. Also, the flaredtip 40 helps prevent charcoal, burned material, and soft wood from becoming jammed in the bore of therigid tubular member 12 when poking at the fire. - Although the invention has been shown and described with reference to specific preferred embodiments, it should be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the following claims. For example, other shapes for the rigid and bendable tubular members, other than cylindrical, can be used to practice the invention.
