I, HERMANN ERDMANN, of 73, Frankfurter Allee, Berlin, in the Empire of
Germany, Druggist, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a gas burner for liquid combustibles such as
spirit, petroleum and the like in which the vaporizing of the fuel takes place
without separate heating device.
In the improved device the combustible rises from the reservoir or container
in the ordinary manner through a wick contained inside a pipe and capable of
being moved up or down by means of a pinion and covered at its upper end by a
sheath or casing forming the vaporiser. The upper cover plate of this vaporiser
casing is perforated and a series of tubes so-called Bunsen tubes, are set on the air
openings and are provided with air inlet openings, the whole of the said tubes
being surrounded at their upper part by an annular casing. This casing forms
a mixing chamber situated above the tubes, in which chamber the mixing of the
combustible gas coming from these tubes, with the air flowing in through the
inlet openings, through the interstices between the tubes, and through other
places provided therefor, is completed. The casing itself may also be provided
with air openings and these again may be made adjustable in size to allow of
the air admission being regulated. A laterally projecting edge or splayed end
on the casing forces the air impinging on the outside of the burner head to
pass between the tubes, into the mixing chamber.
When the burner is to be set in operation, the wick is moved so far downwards
by means of the pinion that it rests with its upper surface at the level of the
lateral openings of the casing and is then ignited through these openings.
After the expiration of about 10 to 15 seconds the flame has so far heated the
vaporising plate that it can itself then effect the vaporising and
for this purpose the wick is moved up to the plate, SO that the
wick flame is extinguished. The combustible coming through the wick in contact
with the hot plate is vaporised, escapes through the tubes upward and after it
has been mixed with air for combustion can be ignited like any other gas
flame.
So long as the upper gas flame burns, a portion of the heat developed by it is
conveyed partly through the casing and tubes or other metal connections and
partly through radiation to the vaporising plate, thus maintaining the latter
at the necessary degree of heat.
By moving the wick up or down the flame may be regulated.
This improved burner may serve for cooking, heating and lighting purposes,
in the latter case for heating incandescent bodies.

I, HERMANN ERDMANN, of 73, Frankfurter Allee, Berlin, in the Empire of
Germany, Druggist, 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 has for its object a gas burner for liquid combustible such as
spirit, petroleum and the like in which the vaporising of the fuel takes place
without separate heating device.
It is shown in the accompanying drawings, Figure 1 being a vertical section
of the reservoir; and Figure 2, a detail view of the burner.
In the improved device the combustible rises from the reservoir or container a
in the ordinary manner through a wick e contained inside a pipe and capable
of being moved up or down by means of a pinion and covered at its upper end
by a sheath or casing & forming the vaporiser. The upper cover plate of this
vaporiser casing d is perforated and a series of tubes g, so-called Bunsen tubes,
are set on the air openings and are provided with air inlet openings i, the whole
of the said tubes being surrounded at their upper part by an annular casing h.
This casing forms a mixing chamber situated above the tubes g in which
chamber the mixing of the combustible gas coming from these tubes, with the
air flowing in through the inlet openings i, through the interstices between the
tubes g and through other places provided therefor, is completed. The casing
itself may also be provided with air openings and these again may be made
adjustable in size to allow of the air admission being regulated. A laterally
projecting edge or splayed end on the casingh forces the air impinging on
the outside of the burner head to pass between the tubes g into the mixing
chamber.
When the burner is to be set in operation, the wick e is moved so far down-
wards by means of the pinion that it rests with its upper surface at the level
of the lateral openings e of the casing d, Figure 2, and is then ignited through
these openings e. After the expiration of about 10 to 15 seconds the flame has
so far heated the vaporising plate d that it can itself then effect the vaporising
and for this purpose the wick c is moved up to the plate d, Figure 1, so that the
wick flame is extinguished. The combustible coming through the wick in
contact with the hot plate is vaporised, escapes through the tubes upward and
after it has been fixed with air for combustion can be ignited like any other
gas flame.
So long as the upper gas flame burns, a portion of the heat developed by it is
conveyed partly through the casing hand tubes or other metal connections g
and partly through radiation to the vaporising plate d, thus maintaining the
latter at the necessary degree of heat.
By moving the wick up or down the flame may be regulated.
This improved burner may serve for cooking, heating and lighting purposes,
in the latter case for heating incandescent bodies.
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. A burner for liquid combustibles, characterised by a perforated vaporising
plate (d) provided with Bunsen or blue flame burner tubes (9) being arranged
above a wick (c) which is adapted to be moved up and down. which lata

page_text: transmits to the surface of the wick a portion of the heat developed by the gas flame
and thus effects the vaporisation of the combustible drawn from the reservoir
by the wick, substantially as described.
2. In a burner wick such as described surrounding the upper ends of the
Bunsen or blue flame burner tubes (g) arranged on the vaporising plate (d)
with an annular casing (h) which forms a mixing chamber above the tubes (g)
for the vaporised combustible and the air for combustion, substantially as
described.
