COMPLETE SPECIFICATION.
A New or Improved Means or Device for Conducting Air to the
Flames of Gas, Petroleum, and other Burners for Lighting and
Heating.
1, AUGUST HEINRICH JULIUS SCHÜLKE of 94 Leipziger-strasse Berlin, in the
Empire of Germany, Engineer, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to a new or improved means or device for conducting air
to the flames of gas, petroleum and other lamps or burners for lighting and heating,
the object of which is to spread out and flatten the flame, whereby the illuminating
surface is enlarged, complete combustion of the gas or vapour is secured, and a
perfectly white flame is produced. By these means it is also possible to burn the
heaviest hydrocarbon vapours and gases without depositing carbon, and without
the necessity of using very fine passages. Besides the abovementioned advantages
the invention affords the further advantages of great simplicity of the burner itself
and the exclusion of all mechanical appliances, which in practice easily get out of
order and the proper use and care of which require a certain amount of experience.
The above mentioned effects of spreading the flame and securing complete
combustion are produced, according to this invention, by an air supplying
device in which the flame itself is situated at the meeting point of two or more jets
of the air intended to support combustion; such jets of air being directed against
one another by suitably formed and directed channels or passages. These jets of
air strike or impinge upon one another and are broken up or finely divided and
thereby effect an energetic spreading out of the flame and a complete combustion
of all the hydrocarbon therein.
In the accompanying drawings Figure 1 is a vertical section of a gas burner
constructed in accordance with my invention and suitable for burning heavy gases.
Figures 2 and 3 are vertical sections, taken at right angles to one another of a
modification of the same.
The burner shown in Figure consists of several small buruer tubes a leading
through the cover of the inlet passage b which screws on to the gas pipe. These
burner tubes pass at their upper ends through a ring c in such manner that they
stand in a circle therein, and the small gas flames burning at the upper ends of
these tubes combine together into a closed crown of flame. In order that this
effect should be accompanied by the widest possible spreading of each small flame
the ring c has on each side of each of the tubes a channels d d' which converge
towards the mouth of each such tube; the said channels serve as air passages, and
allow the air entering through the openings f of the burner jacket e below the
chimney h, to act in jets directed against one another and against each small flame
somewhat like the jet from a blow pipe.
In the burner shown in Figures 2 and 3, in which there is only one central
burner tube a', the air channels d d' are formed in the cast body g which contains
the screw thread for screwing it on to the gas pipe, and at the same time forms the
gallery for the chimney h. The above described air supplying device can also be
used in petroleum, spirit and other lamps fed with liquid combustible material and
renders lamps of that kind suitable for the employment of incandescent bodies. In
gas flames the employment of incandescent bodies is sometimes rendered very

page_text: difficult, or impossible by reason of the deposit of soot from the flame of the gas,
and because the flame does not spread over the whole of the incandescent body,
but generally leaves a dark kernel or core at the upper part. All these incon-
veniences in flames with incandescent bodies are avoided completely by the air
supplying device above described.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The new or improved means or device for conducting air to the flames of lighting
and heating burners which consists of channels or passages d d' so arranged and
adapted that the streams or jets of air delivered by them to support combustion
are caused to strike or impinge against each other, and against the flames in such
manner that the said flames are spread out, and complete combustion secured,
substantially as described.
