BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates generally to joints for sections of tapered chimneys used in tents and to stoves mounted on chimneys that support tents

2. Description of Prior Art

Lightweight liquid fueled stoves are widely used by outdoor travelers today who demand the smallest, lightest equipment. The stoves have no chimney so are essentially only good for fair weather use outside the tent. When caught in cold, wet, windy weather many campers ignore the obvious hazards and light the stove inside their tent if they can't run for home. Liquid fuel has to be packed in, the longer the trip the more weight to be carried.

Usually deadwood is readily available where backpackers travel. It is logical to use a wood burning stove for heating and cooking in the comfortable shelter of a tent in any kind of weather. Wood stoves, however, have not been accepted by many backpackers because of problems with stoves and the serious need for a safe dependable chimney.

Some problems are as follows:

1. Tapered pipe sections are used for camp stove chimneys because one section slides totally into another for convenient packing. The traditional method of joining two sections of tapered or straight stove pipe is by crimping one end of pipe to make the diameter small enough to fit into the end of another section that has not been crimped. Straight pipe sections overlap each other as much as the length of crimping. The length of overlap with tapered pipe is limited because of the taper. This short overlap at the crimped joint of tapered stove pipe puts high pressures on the metal in the region of the joint. As a result light thin gauge metal can not be used for tapered stove pipe. Chimneys using this crimped joint for tapered or straight pipe cannot support the weight of a tent.

2. Chimneys using this crimped joint in windy conditions are subject to disconnection from the stove or the pipe joints when the pipe sits in the stove connection and passes through a roof jack. Wind on the tent roof jerks the roof jack up and down sometimes pulling apart the connections. The chimney is loose and bearing no weight.

3. Chimneys exiting the tent through the side wall or a low part of the tent roof are usually too hot to be safe. The roof jack is too close to the stove.

4. If chimney and stove both sit on the ground, the coupling between them can be strained by the movement of the chimney and not the stove.

5. A separate pole must be carried to support the tent if the chimney is not used for support.

6. A horizontal stove position causes the radiant heat to beam mostly up and down not as much outward to the occupants of the tent. Radiant heat is the most useful type of heat in a tent.

7. Wood can not be stacked vertical and burned from the top down using a clean burn gassifier method in a horizontal stove.

8. The hottest part of prior art camp stoves is the stove to chimney port not the cooking surface. A large hot fire is needed to keep the cooking surface hot enough. A large portion of heat is lost up the chimney.

9. Hot fly ash burns holes in the tent and may be the surrounding forest if a spark arrester is not used. Screens often plug and have to be taken off and cleaned and this usually happens when there is a fire in the stove and the screen is to hot to handle.

OBJECTS AND ADVANTAGES

Accordingly several objects and advantages of the present invention solve important problems of chimneys and stoves for tents.

1. To provide a tapered chimney made from multiple sections of tapered stove pipe butt joined with a tapered coupler sleeve at each connection. The tapered coupler sleeve is sized to tighten as it slides into place, centering over the butt joint. This assembly makes a strong safe chimney even when fabricated with light gauge metal.

2. To provide a tapered chimney using the new joint to fit any camp stove.

3. To provide a metal roof jack that is shaped to allow a cooling passage of air.

4. To provide a chimney using the new joint to support a tent. A carrier with an inner and outer flange and upper and lower collar is placed on the chimney top. The upper collar passing through a tent roof jack and the roof jack resting on the outer flange. The inner flange is a stop for the chimney top. The outer flange has evenly spaced attachment points for multiple of cords tied to a horizontal hoop encircling the chimney not attached to a tent. Sections of flexible tent poles are put together to form a complete circle or hoop which is a new use for this type of pole that is commonly used in dome tents. This arrangement gives umbrella type support to a tent.

5. To provide a boiler fitted on the upper collar of the carrier outside of a tent to capture heat at the top of the chimney. The boiler channels heat around a container to be heated. The container is fitted with a bail and can be lifted out with a stick. Capturing heat from the a top of the chimney of a camp stove is a new idea that can only be used with a chimney that can bear weight.

6. To provide a base for the chimney to sit upon. A base cup to support the bottom of the chimney is welded to a base collar with two opposite support notches to hold a long piece of fire wood under and perpendicular to the chimney. The ends of the wood are used as handles to adjust the position of a hot chimney-stove assembly and also serves as a bridge across melted snow under the chimney.

7. To provide a stove mounted vertical on the chimney enabling the chimney-stove assembly to be locked together for safety giving the unit one pivot point at the chimney base. The chimney bears weight so it is stable and secure.

8. To provide a stove mounted vertically on the chimney to radiate heat outward to the occupants of a tent, not as much up and down as is the case with a horizontal mount. Radiant heat is the most useful type of heat in a tent with no insulation.

9. To provide a baffle inside the stove mounted parallel to the cooking surface. A smoke port in the baffle near the front of the stove directs and concentrates heat under the cooking surface making it the hottest part of the stove. The baffle steps down to make space for a rectangular smoke port in the back of the stove. A small fire keeps the cooking surface hot.

10. The baffle of item #9 also slows and cools hot fly ash thereby protecting a tent or forest from burning. A spark arrester screen is not usually needed.

11. To provide a stove that simmers very well burning one piece of wood at a time and keeping the cooking surface hot (300F-700F). This is made possible by a small square grate (approximately 1¾ in. square for a 6 in. stove top) in a cone shaped bottom cover of the stove which concentrates draft directly on the small burn. The cone shape causes burning material to roll down over the grate. This bottom primary draft volume is controlled by two opposed sliding doors meeting at the center controlling how hot and how fast the wood burns.

12. To provide a stove that is mounted vertically on the chimney so that a full load of wood can be stacked vertical and burn slowly from the top down. The gas burns at the top, as the wood at the bottom is heated giving a steady, clean, gasifying type burn. The secondary combustion air used to burn the gas enters a partly open vertically sliding front feed door supplying a horizontal wide band (about ⅓ diameter of the stove) of air directed at the upper part of the fire. The flames are forced to the back of the stove, setting up a circular turbulence directing the flames back and up past hot parts of the baffle to the small round smoke port in the baffle near the front of the stove and under the cooking surface.

13. This simple method of burning wood is the answer to a search for a cook stove to reduce the waste of wood using inefficient stoves and 3 rock open fires in third world countries. Features of this cook stove that will save wood are cylinder shape, vertical position, cone shaped restricted bottom primary draft, baffle and secondary upper air. When using the new stove described above, 400 grams or just under a pound of wood will keep a six inch stove top hot (300F-700F) for at least one hour. The wood will last even longer if the sides of the combustion chamber are insulated when only cooking heat is required.

14. To provide another embodiment for the feed door of item #12 when a cooking pot is larger than the stove top and prevents the sliding door from opening completely. A feed door hinged at the top is used. The door can be partly open to provide the wide band of secondary draft at the bottom. The sides of the door jamb stop air entering the stove at the sides of the door when the door is partly open.

15. To provide a V shaped heat shield under the bottom cover to protect what ever is under the stove and also collect ashes continually from the grate thereby leaving no trace of lighting a wood fire.

16. Recycled steel cans of various heights and diameters are used for the stove body, boiler and water container. Stainless steel or titanium however are the best metals for all parts. The baffle is secured to the can (stove body) by bending special edges of the can and baffle with a pair of pliers.

17. Two stoves can be mounted on one chimney when up to six people use a bigger tent.

18. To pack for traveling, the tapered chimney sections fit one inside the other. The sleeves, chimney extension, base, carrier, door, connector and a heat shield all fit inside the stove.

19. The chimney stove assembly (6 in. stove top, 3 in. chimney) can be made to weigh as little as 2 pounds with steel and aluminum and much less with titanium. Additional objects and advantages will be revealed in the details of the drawings and description.

SUMMARY

In accordance with the present invention a tapered pipe sleeve joins tapered chimney pipe sections in a butt joint. The chimney has a top carrier for tent support, a bottom base to support chimney and stove mounted vertically on the side of the chimney.

Important parts of the stove are; a cone shaped bottom with a grate in the small end that gives a turbo like velocity to the incoming draft for a small hot fire; the baffle in the stove makes the cooking surface hottest part of stove and stops hot fly ash from passing out the chimney. The V shaped heat shield collects ashes outside the stove as the fire burns leaving no fire place scar in the woods; no trace camping.

DETAILED DESCRIPTION
FIGS. 1 to 11—Preferred Embodiment
Chimney (FIG. 1)

Tapered chimney pipe sections, upper 34 and lower 36 (FIG. 1) are held together with a tapered coupler sleeve 35 which becomes tight on both chimney pipe section ends as it slides into place centering over the tapered pipe ends making a butt joint. Multiples of this joint assembly can be used to make a chimney for most stoves. A chimney using the tapered coupler sleeve butt joint can bear weight, even when made with thin metal.

Carrier 28 (FIG. 2)

A chimney top carrier 28 (FIG. 2) is used to attach a number of items that the chimney can support. The carrier is attached to the chimney with lower collar 31 and an inner flange 32 which rests on the chimney top.

Roof Jack 24 (FIGS. 3A,B)

A tent is supported when attached to a metal roof jack 24 (FIGS. 3A, 3B) which rests on the carrier 28 outer flange 33 (FIG. 2). The metal roof jack 24 has a top outside round plate 26 (FIG. 3A) with pie shaped segments of the center, cut to form wrap tabs 25 shown in FIG. 3B. The fabric of a tent is sandwiched between the top plate 26 and bottom plate 27. The wrap tabs 25 of plate 26 are bent around the edges of the chimney holes to lay against the under side of bottom plate 27. Tent weight pressure on the roof jack wrap tabs 25 resting on the carrier outer flange 33 keeps the roof jack 24 parts together. The polygon shape of the roof jack chimney hole allow cooling air to pass by carrier collar 30 and also makes minimal contact with the carrier collar 30 and flange 33.

Hoop 72 (FIG. 10)

The carrier 28 (FIG. 2) gives support for a hoop 72 (FIG. 10) suspended by cords 73 from attachment points 29. A wire laced through holes drilled at intervals in the outer flange 33 provide points 29 to attach cords 73 (FIG. 10) for supporting a hoop 72 (FIG. 10) made from flexible tent poles. The hoop provides umbrella shaped support for a tent.

Chimney extension 74 (FIG. 11) A chimney extension 74 (FIG. 10) is attached to the carrier 28 upper collar 30 (FIG. 2).

Boiler 20 (FIG. 1)

A chimney top boiler assembly 20 (FIG. 1) attached to the carrier 28 (FIG. 2) is supported by the chimney. The boiler fits on upper collar 30 and channels hot smoke around container 23 which is held in position by spacers. A bail 22 for lifting out the container 23 is provided. This chimney top boiler 20 uses heat that is otherwise wasted and can only be used on a chimney which can bear weight, such as the one described above.

Base 50 (FIG. 4).

The load bearing chimney rests in base cup 51 (FIG. 4) which stops air entering the bottom of the chimney. The cup 51 is welded to a base collar 52 (FIG. 4). A suitable piece of fire wood is placed in the support notches 53 under and perpendicular to the chimney, forming a bridge over melted snow and providing the ends of the firewood as handles to adjust the position of a hot stove-chimney assembly.

Stove Body 65 (FIG. 9)

The stove body 65 (FIG. 9) is cylinder shaped which helps intensify the reflection of heat to the center of the combustion chamber. The stove is mounted on the chimney vertically for optimum radiated heat outward to the occupants of the shelter. It is possible to make the stove body 65 (FIG. 9) from an open used steel can. A rectangular door jamb cut out 67 (FIG. 9) is made on one side and a stove smoke cut out 69 is made directly opposite in the back of the stove body 65. Two sets of tabs are cut on the stove body 65 to be bent over when a baffle 60 (FIG. 8) is installed. These tabs are upper tabs 68 (FIG. 9) at the upper edge the door jamb cut out 67 and smoke tabs 70 at the lower edge of the stove smoke cut out 69.

Baffle 60 (FIG. 8)

A baffle 60 (FIG. 8) is installed to stop hot sparks from burning holes in a tent and to make the cooking surface the hottest part of the stove. Cuts are made to form flexible edges 64 (FIG. 8) and when slightly bent follow the contours of the inside of the stove body. The baffle 60 is pushed into the open end of the stove body 65 (FIG. 9) and the spacer legs 61 (FIG. 8) are forced tight against the inside of the closed end of the stove body 65. Baffle mounting tabs 63 (FIG. 8) are made to extend outside of stove smoke cut out 69 (FIG. 9) at the back of the stove and are bent around smoke tabs 70 (FIG. 9) and then both together are bent down. Upper tabs 66 (FIG. 9) are bent up inside, against the baffle in front. This method of installing the baffle enables it to be installed in the field into a recycled can with tin snip and pliers. All the smoke is forced to pass through the baffle smoke port 62 (FIG. 8) directly under the cooking surface making it the hottest part of the stove also concentrating the smoke for a more compete burn and stopping hot fly ash from burning holes in a tent.

Connector 44 (FIGS. 6A,B)

The stove is attached to the chimney with connector 44 (FIGS. 6A, 6B). Smoke pipe 46 conducts smoke from stove to chimney. Flange hooks 48 and 49 on top of the connector 44 are each hooked inside, one in the stove smoke cut out 69 (FIG. 9) and one in the chimney smoke cut out 38 (FIG. 1). A connector spacer 45 on each side of the connector 45 stops air leakage and makes a tight contact between stove and chimney. A space flap 47 (FIG. 6B) seals the space formed at the bottom of the stove smoke cut out 69 because the weight of the stove makes it tight on the connector at the top with a space at the bottom.

Bottom Cover 54 (FIGS. 7A,B)

A square grate 55 is secured in the lower portion of a cone shaped bottom cover 54 (FIGS. 7A, 7B). The bottom cover 54 is attached to the stove and chimney with two pointed hooks, one at the back is stationary and penetrates stationary hook hole 37 (FIG. 1) in lower chimney section 36. The over center hook 56 at the front is drawn by an over center lever to penetrate the over center hook hole 71 (FIG. 9) below the door jamb cut out 67 (FIG. 9) of the stove body. Three keeper clamps 59 (FIG. 7A) contact the ridge that occurs at the edge of all recycled cans (stove body FIG. 9). Two slide doors 58 (FIG. 7B) meeting at the center of the bottom cover 54 supply concentrated intense draft for a clean burn of a small fire. The flames pass through the baffle 60 (FIG. 8) keeping the cooking surface hot (300F-700F), burning one piece of wood at a time. For a controlled slow gasifying of a full load of wood the slide doors 58 limit the primary draft.

Door Jamb 39 (FIGS. 5A,B)

Secondary combustion air required to burn the hot gases in the top of the stove is supplied by partly opening a vertically sliding feed door 40 (FIG. 5A). This secondary air comes into the stove as a wide horizontal band (near ⅓ diameter of the stove) directed at the top portion of the fire. This causes a circular turbulence to the back of the stove past hot parts of the baffle up to the small round baffle smoke port 62 (FIG. 8) under the cooking surface. The feed door 40 slides in door tracks 41 on either side of the door jamb 39 (FIGS. 5A, 5B). The removable door jamb is attached to the stove body 65 (FIG. 9) by inserting the door tracks 41 into the stove door jamb cut out 67. The top of the door tracks 41 come out of door jamb cut out 67 through door jamb slits 66 on the upper corners of door jamb cut out 67. The lower portion of the door tracks 41 are held tight against the body inside by outside horizontal stops 43 (FIG. 5A) on each side. Vertical movement is controlled by inside vertical stops 42 on each side. The door jamb also serves as an ash shelf to catch hot coals that might fall out of the feed door or to aid in feeding the fire.

Heat Shield 75 (FIG. 11)

A heat shield 75 (FIG. 11) hangs on the stationary hook 57 (FIG. 7A) which penetrates mount hole 76 in the shield and stationary hook hole 37 (FIG. 1) in the chimney. The heat shield 75 collects ashes continually protecting a tent or forest floor. These features allow campers to have a wood fire and leave no trace of their camping activities. The V shape of the shield is important to make it easy to fit into the round stove body for packing and also the V bottom of the shield projects radiant heat sideways instead of straight down.

The above description shows parts made in a home shop. The preferred embodiment has been presented however many parts will be made in the future with automatic sheet metal machinery. Other embodiments may be used which will not alter the basic ideas of the invention.

The tapered pipe sleeve used to couple tapered chimney pipes with a butt joint is a new concept that makes it possible for the chimney to support a tent, a boiler 20, hoop 72, stove. This tapered sleeve joint method of joining thin wall pipe is superior to all other types of joints.
