This improved spirit burner has the advantage, that without using a wick the
produced gases are burned in the most perfect manner, so that an essential saving
of spirit is effected.
This spirit burner is constructed in the following manner:-
The spirit is conducted through a tube to an evaporizer of circular form and
is by means of interceptors provided in the evaporizer caused to come in contact
with much of the interior heated surface of the evaporizer. These interceptors
may be in the form of flat partitions radial to the sides of the evaporizer or they

into which is fitted a screw valve. This screw valve is diminished at one end
which forms the real valve and serves for closing the tube. On the under part of
the enlargement of this tube there is arranged a pipe which is provided with an
opening and reaches into an enlargement of the gas distributor. This gas distri-
butor, which is arranged beneath the evaporizer and is conveniently connected
with the same is in the form of a ring and is provided with inner and outer holes
through which the spirit vapors can escape. Underneath the opening in the tube
above mentioned there is arranged a channel which serves for catching the spirit
passing out of the evaporizer and for conducting it to a receiver, after the valve
is opened.
When the spirit collected in the receiver is lighted, the flame of the same heats
the gas distributor and also the evaporizer to such a point that the spirit in the
evaporizer is vaporized and enters in a gaseous form through the opening of the
tube into the gas distributor. The escaping gases carry air with them, which can
enter through the opening, whereupon the mixture passes through the holes and
is ignited. As soon as the spirit passes through the opening in a gaseous form,
the spirit no longer passes to the receiver, so that the working of the apparatus
is entirely automatical.
The flame is regulated by means of the valve.
In order that the pressure in the evaporizer does not force the spirit back
through the admission tube, it is convenient to introduce in this tube à block of
porous material, asbestos or the like.

I, OTTO KEIDEL, of Sangerhausen, in the Empire of Germany, Director, 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 improved spirit burner has the advantage, that without using a wick the
gases produced are burned in the most perfect manner, so that an essential saving
of spirit is effected.
In the annexed drawing-Fig. 1 is a vertical section through the burner.
Fig. 2 is a plan thereof, and Fig. 3 is a plan or another form of construction of
the vaporizer.
This spirit burner is constructed in the following manner.
The spirit is brought through a tube 1 to the vaporizer 2 and by means of inter-
ceptors 3 provided in the vaporizer is caused to come in contact with much of the
interior heated surface of the vaporizer.
These interceptors 3 may be in the form of flat partitions radial to the sides
of the vaporizer (Fig. 2) or they may be of circular form and placed at equal
distances from the same (Fig. 3). It is only of importance to give to the spirit
as large a vaporizing surface as possible. The spirit passes from the vaporizer 2
into a tube 4. This tube 4 has an enlargement 5, in which a valve is fitted, in
the present case a screw valve 6. This screw valve 6 is diminished at one end 7,
which forms the real valve and serves for closing the tube 4. With the under
part of the enlargement of this tube 5 there communicates a pipe 8, which is
provided with an opening 9 and reaches into an enlargement 10 of the
gas distri-
butor 11. This gas distributor 11, which is arranged beneath the vaporizer 2 and
is conveniently connected with the same, is in the form of a ring and is provided
with inner and outer holes through which the spirit vapors can escape. Under-
neath the opening in the tube 8 above mentioned there is arranged a channel 13,
which serves for catching liquid spirit passing out of the vaporizer 2 by means of
the tube 8 on opening the valve 7. This spirit passes through the hole 16 into the
channel 13 which carries it to the receiver 14.
When the spirit collected in the receiver 14 is lighted, the flame heats the gas
distributor 11 and also the vaporizer 2 to such a point that the spirit in the vapor-
izer 2 is vaporized and enters in a gaseous form through the opening of the
tube 8 into the gas distributor 11. The escaping gases carry air with them, which
can enter through the opening 16, whereupon the mixture passes through the
holes 12 and is lighted. As soon as the spirit passes through the opening 9 in a
gaseous form, liquid spirit no longer passes to the receiver 14, so that the working
of the apparatus becomes entirely automatic.
The flame is regulated by means of the valve 7:
The pressure in the vaporizer 2 tends to press the spirit back to the admission
tube. Also when the spirit reaches the place, where the feed tube is hot, the
flame would he suddenly increased under the effect of sudden vaporizing.
In order that the pressure in the evaporizer does not force the spirit back
through the admission tube 1, it is convenient to introduce in this tube a block 15
of porous material such as asbestos or the like.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:
An improved spirit burner having a vaporizer 2 provided with an admission
tube 1, in which the liquid fuel comes into contact with a number of interceptors 3

page_text: for facilitating the vaporization, the spirit vapors leaving the vaporizer 2 through
the tubes 4 and 8 in a quantity to be regulated at pleasure by means of the valve 7.
2. An improved spirit burner in which the spirit passes before vaporization
into a receiver 14 in which it is lighted for the purpose of warming the vaporizer 2.
3. An improved spirit burner in which the spirit vapors mixed with air pass
from the tube 8 directly into a gas distributor 11, from which the gas mixture
passes through holes 12 beneath the vaporizer and is there lighted.
