Patented June 27, 1944 massasss YOILBJURNING HEATING STOVE Wolfgang Julius Mag,:-Melbourne, Victoria, .Australia Application April 21, 1942, Serial 'No. 439,812 In Australia December-4. 1941 3 Claims.
The present invention relates to heating stoves or cookers of the oil burner type wherein the oil fed from the oil container is vaporised bythe heat of the metal constituting the burner and in which a burner jet is fitted. One example of the type mentioned is well known under the registered word trade-mark Primus.
In the type of stove above defined, the jet is arranged in a vertical plane with the burner jet disposed to direct the gas upwardly into the atmosphere disposed above the burner. Consequent upon the disposition stated of the burner jet, the path of the gas issuing therefrom is .unidirectional with the flame, whereby the heat of combustion is led away from the metal of the burner which latter is required to be maintained at a temperature operating to cause continuous vaporisation of the oil, the resulting gas being burned at the burner jet.
The present invention has been devised to provide a construction in stoves of the type abovementioned, wherein the gas issuing from the jet is downwardly directed in contra flow to the flame whereby the heat of combustion is so directed that it impinges upon the metal constituting the burner and during the whole period of operation of the stove the burner is directly located in the heat of combustion to ensure continuous and eiiicient vaporisation of the oil.
According to this invention a feed pipe leading from the oil container delivers into the neck of the burner which latter is disposed horizontally and the jetof the burner projects downwardly from the latter to be located directly over a flame deflector which is disposed below said jet and causes the direction of the gas to be reversed upwardly and set up a tubular column which impinges upon the burner so that the latter is continuously located in the heat of the flame.
The marginal region of the burner is preferably castellated so that the flame deflected to impinge upon and flowing past the burner is divided into a plurality of jets which during the operation of the stove continuously play on the burner.
The accompanying drawing depicts practical arrangements in accordance with the invention.
In this drawing:
Fig. 1 is a vertical sectional elevation showing the burner with its associated flame deflector and mounted upon the oil container.
Fig. 2 is a top plan, and Fig. 3 an underneath plan of the burner.
Fig. 4 is an enlarged side elevation of the burner and flame deflector.
Referring to Figs. 1 to 4 inclusive, projecting upwardly from the container 6 is a pipe I communicating with the oil in the container and offset for mechanical coupling as by the union nut 8 to the bore 9 of the horizontally disposed neck III of the circular burner head I I.
The bore 9 of the neck III communicates with a vertically disposed bore I2 in the burner head I I, which latter bore is screw threaded to detachably receive the jet I3. The lower face of the burner head I I registers over the concaved flame deflector I4.
The flame deflector I4 can also be used for the combustion of a volatile fuel such as methylated spirits to heat up the burner head II and set up initial vaporization of the oil when starting up the heating stove.
Alternatively a cup such as that provided by the depression at A in the container 6 may be used to receive the volatile fuel mentioned.
The lower face of the burner head II is castellated as shown so that a circumferential series of passages I5 are provided to set up a plurality of jets of flame from the jet I 3 deflected upwardly by the flame deflector I4.
The flame deflector I4 is mounted for removal out of register with the lower face of the burner I I and for that purpose is shown in Figs. 1 and 4 supported by its stem I6 fitted into an aperture in the lower bridging member I'I'of a stirrup I8,
the upper bridging member I9 of the latter de- I tachably resting in a transverse groove 20 in the upper face of the burner head I I.
In practice I have found that efficient results are obtained by arranging the flame deflector I4 about one half of one inch below the jet I3 with the cross-sectional area of said deflector substantially less than that of the lower face of the burner head II with the latter face approximately twice the surface area of the upper face of the deflector I4.
In use, when it is required to replace or clean the jet I3, it is convenient to remove the flame deflector I4 out of register with the burner head II and consequent upon the inverted arrangement of the jet I3 and the gas being reflected to flow upwardly and about the burner head I I, heat is being continuously applied to the latter and ensures continuity of efiicient vaporisation of the oil.
Furthermore, on account of the inverted position of the jet I3 there is less liability for dirt or carbon to accumulate therein.
I claim:
1. In an oil burning heating stove of the type specified, an oil container, a vertically disposed oil supply pipe in communication with and projecting upwardly from said oil container, a horizontal ofiset from said pipe, a hollow burner head, said head having a horizontal tubular neck connected to said oflset and a downwardly delivering jet nozzle, a stirrup supported by and depending from the burner head and including a lower bridging member having an aperture therein, and a flame deflector having a stem removably seating in said aperture to locate the flame deflector below and in alignment with said jet nozzle.
2. In an oil burning heating stove of the type specified, an oil container, a vertically disposed oil supply pipe in communication with and projecting from said oil container, a horizontal offset from siad pipe, a hollow burner head connected to said offset said head having a downwardly delivering jet nozzle and a castellated marginal re--. gion surrounding said jet nozzle, a stirrup supported by and depending from the burner head and including a lower bridging member, and a flame deflector arranged on said bridging member below and in alignment with said jet nozzle.
3. In an oil burning heating stove of the type specified, an oil container, a vertically disposed oil supply pipe in communication with and projecting from said oil container, a horizontal olfset from said pipe, a hollow burner head connected to said offset, said head having a downwardly delivering jet nozzle and a castellated marginal region surrounding said jet nozzle, :1 stirrup supported by and depending from the burner head and including a lower bridging member, and a concaved flame deflector on said bridging member below and in alignment with said jet nozzle.
