Improvements in Oil Vapour Burners.
I, GEORGE CROYDON MARKS, of 18 Southampton Buildings, Chancery Lane,
London W.C., Consulting Engineer, (a communication from Jules Gilbert of
42 Boulevard Bonne Nouvelle, Paris, in the Republic of France, Banker), do hereby
declare the nature of this invention to be as follows:-
My invention pertains to improvements in burners for the utilization more
particularly of heavy oils for the production of an atmospheric non-luminous flame
capable of heating an illuminated mantle to incandescence, and has for its object to
more effectually produce the vaporisation of the oil supplied and the production of a
flame of intense heat in which perfect combustion is effected.
In carrying my invention into effect I mount a reservoir containing the oil supply
preferably in a position above the gas burner, so that a certain amount of pressure is
produced capable of supplying the oil to the vaporising chamber. I conduct the oil
from the reservoir to the burner by means of a suitable pipe which is utilized for the
additional purpose of carrying the burner and appendages, and I provide a suitable
cock for the admission or closure of the supply.
I arrange my burner as a mixing chamber having its lower aperture open for the
admission of air, while its upper surface I provide with gauze through which a
mixture of gas and air may pass to form the flame. I arrange the vaporising chamber
projecting above the flame aperture, so that on the burning of the mixture heat will
be communicated to said chamber and the oil which is supplied therein, will be
vaporised and conducted therefrom to a nozzle or nozzles issuing into the mixing
chamber.
I conduct the oil into the vaporising chamber through tubes which are filled with
a bundle of thin metallic wire or threads which terminate on entry into the chamber,
so that the oil is fed and regulated by capillary action. These supply tubes may be
either arranged within the mixing chamber, or partly within and partly without.
From the vaporising chamber I conduct tubes to the nozzle preferably provided at the
lower aperture of the mixing chamber, where on issue of the gas from the vaporising
chamber a current will be induced and a mixture of gas and air will be produced for
feeding the flame. The vaporising chamber projecting into the flame area is
continually heated so that a continuous supply of gas is produced.
Instead of arranging the oil reservoir above the burner for the supply of the oil by
gravity, I may arrange the burner upon a reservoir into which air may be forced, and
by pressure of the air so compressed the oil may be fed into the vaporising chamber
for producing the flame as before described. I may effect the initial heating of the
vaporising chamber by any suitable means such as a spirit lamp.
In carrying my invention into effect in accordance with a modified design I arrange
the vaporising chamber as an annular chamber supporting the gauze, and carrying at
the same time a tube projecting therefrom into the flame area so that sufficient heat
may be communicated to the vaporising chamber for the vaporisation of the oil fed
therein.

page_text: I sometimes prefer to arrange a single pipe or tube to carry the bundle of thin
metallic wire or thread which I employ, and this tube I arrange to project within the
vaporising chamber with its extremity terininating at a distance above the surrounding
flame aperture so that the vaporisation may occur on the issue of the oil at the
extremity of the feeding tube. The gas so produced descends and issues into the 5
mixing chamber by means of jets arranged at the lower aperture thereof.
Dated this 26th day of October 1896.

I, GEORGE CROYDON MARKS, of 18 Southampton Buildings, Chancery Lane,
London, W.C. Consulting Engineer (a communication from Jules Gilbert of
42 Boulevard Bonne Nouvelle, Paris, in the Republic of France, Banker), 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:-
My invention relates to improvements in burners for the utilisation more particularly
of heavy oils for the production of a non-luminous flame capable of beating an
illuminating mantle to incandescence and has for its object to more effectually
produce the vapourization of the oil supplied and the production of a constant flame
of intense heat in which perfect combustion is effected.
In the accompanying drawings;-
Figure 1 is a side elevation showing the application of my invention.
Figure 2 is a sectional elevation of a burner made in accordance with my
invention upon a larger scale than in Figure 1.
Figure 3 is a sectional elevation of a modified form of burner applied upon an
oil reservoir..
Figures 4 and 5 are sectional elevations of further constructional modifications.
In carrying my invention into effect as illustrated in the accompanying drawings
similar portions on the different modifications are similarly lettered. I mount a
reservoir R containing the oil supply preferably in a position above the burner so
that a certain amount of pressure is produced for supplying the oil to the vapourising
chamber; I conduct the oil from the reservoir R to the burner by means of a suitable
pipe or pipes A which is or are utilised for the additional purpose of carrying the
burner and mantle M, and I provide a suitable cock B for the admission or closure of
the supply.
I arrange my burner as a nixing chamber E having its lower aperture open for the
admission of air, while its upper aperture I provide with gauze G or a perforated
surface through which the mixture of gas and air may pass to form the flame. I
arrange the vapourizing chamber C projecting above the gauze G so that such may
be exposed to the flame and that thereby heat may be communicated to said chamber
and the oil which is supplied therein may be vapourized.
I conduct the oil into the vapourizing chamber C through tubes A which are filled
with a bundle of thin metallic wire or threads a which terminate on entry into the
chamber, so that the oil is fed and regulated by capillary action.
It will be understood that the function of the bundle of thin metallic wire or
threads is to regulate or restrain the issue of oil into the vapourizing chamber-and
by conduction to effect the preliminary heating of the oil supply so that on entry
into the vapourising chamber vapourisation may be completely effected.

page_text: The supply tubes A may be either arranged within the mixing chamber E as
illustrated in Figure 3 or partly within and partly without as illustrated in
Figures 1 and 2, or wholly without as in Figure 5.
From the vapourising chamber C I conduct tubes T T to a nozzle or nozzles D
provided in the lower aperture of the mixing chamber where on issue of the gas from
the vapourising chamber a current will be induced and the mixture of gas and air
produced for continuously feeding the flame.
I may effect the initial heating of the vapourising chamber C by any suitable
means such as the application of the flame of a spirit lamp but as the extremity of
the vapourising chamber is exposed to the flame and oil is uniformly fed into the
vapourising chamber the flame is continuously and uniformly maintained.
Instead of arranging the oil reservoir above the burner for the supply of oil thereto
by gravity I may arrange the burner upon a reservoir H as illustrated in Figure 3
into which air may be forced by means of the pump P and by the pressure of air so
compressed oil may be fed through the supply tube I to the vaporising camber for
the production of a flame as above described.
In carrying my invention into effect according to a modified design I arrange the
vapourising chamber E in an annular form as shown on Figure 5 supporting the
gauze or perforated plate G which carries at the same time a tube N which projects
into the flame area and is exposed to the flame so that sufficient heat may
be communicated to the vapourising chamber for the vapourisation of oil fed
therein.
I sometimes prefer to arrange a single pipe or tube All as illustrated in Figure 4
to carry the bundle of thin metallic wire or threads a which I employ, and this tube
I arrange to project within a vapourising chamber V and the vapourising chamber V
to project above the gauze G so as to be exposed to the flame. The gas produced by
vapourisation of the oil issuing at the extremity of the feeding tube A descends and
issues into the mixing chamber E by means of jets D arranged at the lower aperture
thereof.
At the upper exposed surface of the mixing chamber V a small communicating
aperturer may be provided.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I
claim is;-
1. In oil burners for the production of a non-luminous flame supply tubes in which
are provided lengthwise thin metallic wires or threads between which the oil supply
is forced and fed to the vapourising chamber by capillary action substantially as
described.
2. In oil burners for the production of a non-luminous flame a vapourising chamber
projecting into the flame area and a supply tube or tubes in which thin metallic
wires or threads are provided lengthwise between which the oil supply is forced and
fed by capillary action substantially as described.
3. Improvements in oil burners substantially as and for the purpose herein before
described and illustrated in the accompanying drawings.
