6 Claims.

This invention relates to improvements in burners and particularly for burners such as hydrocarbon burners. One object of the invention is to provide an improvement in a burner f maximum simplicity and easy assembly and disassembly which may be used for example as a tent stove burner for camping or Army use.

Another object is to provide an improved means for supplying tertiary air to such a burner and for spreading the flame.

Another object is to provide means for applying a pot type burner to a small demountable stove or heater.

Other objects will appear from time to time throughout the specication and claims.

The invention is illustrated more or less diagrammatically in the accompanying drawings, wherein Figure 1 is a vertical axial section;

Figure 2 is a view looking in the direction of the arrows 2-2 of Figure l;

Figure 3 is a section along the line 3-3 of Figure 1;

Figure 4 is a section along the line d--t of Figure l.

Like parts are indicated by like characters throughout the specification and drawings.

Referring to thedrawings, I generally indicates a lower member of a demountable burner. It is shown aS having a closed bottom 2, side door opening 3, and an upper edge 6. Resting upon the upper edge 3 is an intermediate supporting ring generally indicated as 5. The ring is shown as having a cylindrical portion 6, fitting within and conforming closely to the upper edge of the member I. Extending outwardly from the top of the cylindrical portion 6 is a, circumferential flange 1, which rests directly upon the upper edge of the member B. It is not important that the iit be too snug as any air which passes through the joint merely increases the supply of air in the space within the member i.

Extending upwardly and outwardly from the ange 1 is the side wall 8 which is more or less outwardly flared and which serves to center andY seat the upper edge of the upper Stove member 9. The stove member is shown as Somewhat upwardly tapered and having a top I0, provided with a gas aperture II, normally closed by the removable closure I2 with the handle I3.

I indicates an upwardly extending tapered sleeve adapted to receive any suitable stove pipe connection I5. The member 5 has an inner downwardly cylindrical portion I6 terminating in an inwardly extending ledge Il.

provided with one or more locking lugs I9 pro- Centered vided with locking notches I9a adapted to engage enlarged portions 20 of the supporting ledge l1, as shown for example in Figures 2 and 3. Thus the pot assembly may be quickly and easily secured to or removed from the intermediate Supporting ring 5 of the stove. Extending inwardly from the top of the cylinder I8 is a ange 2l herein shown as having a plurality of tertiary air inlet apertures 22 extending circumferentially thereabout. Resting upon the flange 2l is the outwardly turned upper edge flange 2E of the pot 23.

The pot is provided with a closed bottom 25. Its wall has therein a plurality of primary air inlet apertures 26 located at various levels. Adjacent the upper edge of the pot, are secondary air inlet apertures 2T which are preferably larger than the apertures 26 and are herein shown in a single row adjacent the open end of the port. The pct may be held in position on the flange 2l by means of a plurality of locking screws 28 which pass through the outer edge of the flame ring 2a and penetrate the iiange 2l. Thus the ange, the -pot and the flame ring may be unitarily Secured together and may be applied to o'r removed from the stove unitarily with the cylindrical supporting sleeve I8. v

The flame ring 29 is provided with a central aperture 3l). Extending up through the central aperture 30 is the air tube 3l which is secured at its bottom as at 32 in an appropriate aperture in the bottom 25 of the pot. Air can thus flow upwardly through the tube 3l. The tube is provided at its upper end fwith an outwardly extending ange 33 upon which is mounted, as by rivets or pins 34, a deiiecting hood 33 with a downwardly extending circumferential iiange 33. Between the ilange 36 and the outer edge of the flange 33, there is defined an air outlet passage 3l through which tertiary air is downwardly directed toward the mixture, escaping upwardly through the central aperture 30 of the flame ring 29. Any suitable fuel is supplied to the lower portion of the pot along the fuel pipe 38. It will be understood that any suitable means may be employed for maintaining a proper supply of fuel at a proper rate of flow. Any suitable controlla'ble valve means not herein shown, may be employed for the rate of flow from pilot rate to high re.

40 indicates a pilot ring mounted on suitable supports 4I and provided with a central aperture 42 aligned with the central aperture 30 oi the name ring and of sutlicient size to give ample clearance about the air tube 3 I In the normal use of the device, the liquid fuel which flows through the pipe 38 is vaporized on the bottom of the pot by the heat of combustion taking place in the air about the pot. When the flow of fuel along the pipe 38 is turned down to a minimum or pilot flow, the lower row oi' primary air inlet apertures 26 below the ring 40, provides the primary air for the vaporized fuel. The mixture of vaporized air and primary air passes upwardly through the primary aperture 42 and is converted into a completely combustible mixture by the air passing inwardly through the primary air inlet apertures 26 above the pilot baille 40. At this stage of combustion, they therefore serve as secondary air supply means for the relatively small amount of fuel vaporized at the pilot stage.

When the rate of ilow isincreased to high fire stage, the level of combustion rises. At the high fire stage, all of the air inlet apertures 26 serve as primary air inlet apertures and the mixture of primary air and vaporized fuel receives its supply of secondary air through the secondary air inlets 2l. This mixture then burns at or above the level of the flame ring 29. In order to provide complete combustion and to form and distribute open top, an intermediate, inwardly extendingpartition ring removably mounted upon the upper edge of said lower stove section, having a central v aperture, an upper stove section removably mounted upon said partition ring, having a circumferential wall and a closed top defining a combustion space, an air directing sleeve mounted upon and upwardly extending from said partition ring, and a burner pot supported on said sleeve and inwardly spaced therefrom, a transversely extending partition connecting the sleeve and the pot, the space between said sleeve and pot being in communication with the air space within the lower section, the wall of said pot being provided with a plurality of primary air inletapertures located at various levels, and having a plurality of secondary air inlet apertures located adjacent the upper edge of the pot, all said apertures being in communication with the space within the lower section below the lower end of said sleeve.
