Definitions

  • ABSTRACT This invention relates to a miniaturized camp stove consisting of a shallow cup-shaped receptacle with a lid that houses a burner and valved gas fitting in disassembled relation. When assembled, the receptacle fits atop of a branch of the gas fitting and provides the support for the cooking vessel when held firmly in place by the burner functioning as a fastener. Another branch of the fitting fastens onto the lid which thus provides a pedestal-type base for the unit.
  • the main stem of the fitting is disposed horizontally with respect to the aforementioned branches and one end thereof houses a hollow needle of the type adapted for insertion into the rubber valve of a fuel canister while the other end contains a flow control valve.
  • diameter of the receptacle and lid is preferably selected to be between approximately 4 and 5 inches so that the unit stands upright on a relatively broad stable base while, at the same time, providing ample support for wide cooking vessels such as skillets and the like.
  • the controls are simple as is the con nection to the fuel cannister which calls for nothing more than the insertion of a needle into a rubber valve in the same manner as is used to inflate most air filled athletic equipment.
  • the LP gas as used for fuel comes prepackaged in a lightweight pressurized cannister and is already in wide use for lanterns, the larger two-bumer camp stoves and tent heaters.
  • a second objective of the invention herein disclosed and claimed is to provide a unit of the type previously mentioned that is virtually wind and weatherproof when in use.
  • Another object is to provide a camp stove ideally suited for backpackers because it is not only extremely lightweight and compact, but it can also be repacked almost immediately after being used because the burner element is housed inside a covered receptacle and the latter dissipates its residual heat very quickly.
  • Still another objective is to provide a campers stove of the type described that uses readily available pre-packaged LP gas as fuel, a pint can of which will last about 6 hours.
  • An additional object is the provision of a lightweight stove in which the burner flame is so confined and directed at the bottom of the cooking vessel that the heat losses are minimal with the result that the unit is both fast and efficient to use.
  • FIG. 1 is a perspective view looking down and slightly to the left at the camp stove in assembled relation ready for use;
  • FIG. 2 is a perspective view from the same vantage point as FIG. 1 except that the unit has been completely disassembled and stored in the container formed by the cup-shaped receptacle and lid therefor;
  • FIG. 3 is still another perspective view from the same position as FIGS. 1 and 2 that differs from the latter view in that the lid has been removed and set off to one side so as to reveal the manner in which the burner, gas fitting and fastener for the base are stored inside the cup-shaped receptacle;
  • FIG. 4 is a side elevation of the stove without a gas cannister attached thereto;
  • FIG. 5 is a top plan view thereof.
  • FIG. 6 is a fragmentary side elevation to an enlarged scale, substantial portions of which have been broken away and shown in diametrical section, revealing the internal construction of the gas fitting together with the connecting portions of the cup-shaped receptacle, lid and burner.
  • reference numeral 10 has been selected to broadly designate the stove and numeral I2 to similarly denote the fuel cannister used therewith.
  • the latter element comprises nothing more than a commercially-available can of LP gas wherein the container 14 is of the pressurizable aerosol type fitted with a rubber valve 16 in the neck 18 of the selfclosing kind that accepts a hollow needle 20.
  • a shallow cup-shaped receptacle 26 forms the bottom of a covered hollow cylindrical container broadly designated by numeral 28 in FIG. 2, the cover for which is provided by lid 30. It has been found that by making the container 28 with a diameter of between approximately 4 and 5 inches and a depth of around 1-52 inches more or less, the interior thereof will easily accommodate the gas fitting 22, the burner 32 and the fastener 34 used to hold the base-forming lid 30 onto the lower upright branch 36 of the gas fitting as revealed most clearly in FIG. 3. These same dimensions result in the extremely compact unit shown in FIG. 2 which will fit easily into a back-pack or even a pant or jacket pocket. Furthermore, as shown in FIGS.
  • the stove in assembled relation provides a broad stable base defined by the lid, an almost equally broad and stable support for the cooking vessel in the form of the cup-shaped receptacle 26, and a relatively low center of gravity aided by the cannister which provides a sort of outrigger type boom or anchor that steadies the entire assembly.
  • the cup-shaped receptacle 26 has a central aperture 38 (FIG. 6) therein sized to loosely receive the externallythreaded neck 40 of upstanding branch 42 of the gas fitting 22.
  • the interally-threaded control aperture 44 in the plate 46 that forms the bottom of the burner screws down onto the neck of the upstanding branch 42 and functions as a fastener holding the cup-shaped receptacle in place on top thereof, all of which is most clearly revealed in FIG. 6.
  • the lower branch 37 of the gas fitting is provided with an internally-threaded socket 48 adapted to receive the screw fastener 34 that passes through the control aperture 50 in the lid 30 and releasably mounts the latter in base-forming position.
  • the lid 30 is bordered by a circumferential skirt 52 that rests upon the ground and provides the space necessary to accept the head of the fastener 34.
  • This screw fastener may, of course, take many forms, the particular one illustrated consisting of a simple slotted head with opposed flats 54 (FIG. 3) ground on opposite sides so that it can be removed with the thumb and forefinger in the absence of a bladed tool. A knurled head or even a wing nut could easily be substituted for the fastener illustrated.
  • the cup-shaped receptacle is bordered by an integrally-formed upstanding annular flange 56 that is generally cylindrical and of substantial height, preferably at least an inch so as to project well above the surface of the burner 32 and provide a shield for the flame eminating therefrom.
  • the upper margin of this flange is pro vided with at least one, and preferably two or more circumferentially elongate notches 58 which cooperate with a cooking vessel (not shown) resting on top of the stove to define slots of sufficient area to permit effective escape of the heated products of combustion and admit enough air to partially support combustion.
  • This flange also confines and directs the flame against the underside of the cooking vessel thus preventing heat losses and conserving the fuel.
  • the main section 60 of this fitting extends horizontally atop integrally formed upstanding lower branch 36 which intersects the latter at a point intermediate the ends thereof and defines a post upon which the remainder of the assembly is supported.
  • the main section 60 has an axial bore 62 therethrough, one end 64 of which is enlarged and internally threaded to receive the valve needle 20.
  • it is hollow and has a port 66 (FIG. 4) in the side thereof through which fuel enters and is conducted on into the axial passage 62.
  • the opposite end of the axial passage is, likewise, enlarged, internally threaded as at 66 and 68 as well as being provided with shaft packing 70 for the stem 72 of flow control valve 24.
  • This valve 24 is nothing more than an axiallyoperated needle valve that closes against a frustoconical seat 74 formed in axial passage 62 immediately upstream of branch passage 76 that opens through the top of the main fitting section opposite lower branch 36.
  • Branch passage 76 extends vertically into an externally and internally-threadedvtubular neck or collar 78 that is integrally formed atop the main section 60 of the fitting in axial alignment with lower branch 36.
  • standing branch 42 actually comprises a separate tubular member in the particular form illustrated which screws onto collar or neck 78 and provides ready access to fuel jet 80 that screws into the interior of said collar. Since the port 82 in jets such as this is quite small and rather easily plugged, it is wise to provide for the removal of tubular upright 42 in order to service the jet. Two opposed holes 84 are provided in the tubular upstanding branch 42 to admit air therein and mix with the fuel exiting from the jet port 82. The upper portion of tubular branch 42 thus forms a mixing chamber for the air and fuel.
  • the camp stove which comprises: a shallow generally cup-shaped receptacle housing a central opening therein and an upstanding annular flange containing at least one vent; a lid sized and adapted to cooperate with the cup-shaped receptacle to define a covered container; gas fitting means having a stem portion intersected intermediate its ends by a cross piece, one end of said stem portion being adapted for connection to the lid so as to produce an upstanding support with said lid functioning as a base therefor, the other end of said stem portion being hollow and terminating in a neck of reduced dimension having an upwardly-facing shoulder at the base thereof, the cross piece having an opening therethrough communicating with the hollow interior of the stem portion to define therewith an inverted T-shaped passage, said T-shaped passage including a valve seat located in one branch of the cross piece facing the other branch thereof; means carried by the branch of the cross piece having the seat therein connectable to a source of fuel; valve means carried by said other branch of the cross piece adapted upon actuation into closed position to engage said valve
  • the vent comprises at least one circumferentially elongate notch in the rim of the upturned flange bordering the cup-shaped receptacle.
  • the lid is bordered by a downtumed skirt and has a centrally-located aperture therein, the portion of the stem resting atop the lid includes a threaded section, and a threaded fastener attachable to the threaded section of the stem holds the latter to the lid when one of said threaded members is passed through the aperture in the latter, the skirt bordering the lid functioning to raise the connection between the stem and fastener into a recessed position therein.
  • the means for connecting the gas fitting to a source of fuel comprises a hollow needle of the type adapted for insertion into the self-closing rubber valve of a pressurized fuel cannister.
  • the subassembly that includes the gas fitting, the valve means and the means connectable to a source of fuel is sized to fit inside the covered container defined by the lid and cup-shaped receptacle.
  • an orificed fuel-metering jet is located within the hollow stem portion, and said hollow stern portion contains an aperture downstream of said jet orifice and upstream of the burner that is open to the atmosphere, said jet being operative to direct fuel past said aperture so as to aspirate air therethrough in sufficient volume to support combustion.
  • valve means is of the needle type adapted to cooperate with the valve seat upon relative movement therebetween to meter the flow of fuel to the burner.
  • the height of the upstanding flange bordering the cup-shaped receptacle is such that the burner lies recessed beneath the rim thereof.
  • the rim of the upstanding flange includes at least two circumferentially elongate notches arranged in angularly-spaced relation to one another, said notches cooperating with the bottom of a cooking vessel resting atop said rim to define slots sized to protect the burner flame from the wind while permitting the heated products of combustion to escape and admitting air to partially support combustion.
  • the camp stove which comprises: a shallow generally cup-shaped receptacle housing a central opening therein and an upstanding annular flange containing at least one vent; a lid sized and adapted to cooperate with the cup-shaped receptacle to define a covered container; gas fitting means having a stem portion joined intermediate its ends by a projecting leg, one end of said stern portion being adapted for connection to the lid so as to produce an upstanding support with said lid functioning as a base therefor, the other end of said stem portion being hollow and terminating in a neck of reduced dimension having an upwardly-facing shoulder at the base thereof, the projecting leg having an opening therethrough communicating with the hollow interior of the stem portion to define therewith an L-shaped passage, means carried by the projecting leg connectable to a source of fuel; and burner means mountable on the neck of the stem portion, said burner means functioning as a fastener to hold the cup-shaped receptacle down against the shoulder with the neck projecting up through the central opening, said gas fitting means, means connectable to
