PROVISIONAL SPECIFICATION.
Improvements in and connected with Petroleum and like Burners
for Cooking and other Purposes.
1, ZACHARI GEORGIEVITCH LESSENKO, of Judin near Semenoffsky Gates,
Moscow, in the Empire of Russia, Lieutenant of Reserve, do hereby declare the
natu.e of this invention to be as follows:-
This invention relates to improvements in and connected with burners for
petroleum and like oils which are more especially adapted for use as stoves for
cooking purposes but also applicable for other heating purposes.
In such stoves as hitherto constructed the petroleum or the like is usually
fed to the burner by air pressure. This arrangement is attended with various
disadvantages which it is the object of the present invention to obviate by
feeding the petroleum or the like to the burner without pressure.
According to my invention I advantageously provide an oil reservoir of annular
cylindrical or other suitable form having at the top an opening through which it
can be filled and at the bottom an outlet by which the petroleum or other oil can
escape through a tube to a vertical vaporizer of annular cylindrical or other
suitable form.
The burner proper consists of a vertical tube having an opening or openings at
the bottom for the entrance of air expanded or enlarged at the upper end, the
expanded or enlarged upper end being preferably covered with wire gauze.
The said burner is connected with the vaporizer by a tube which issues from
the latter at a point above the level of the oil in the reservoir, passes over the
expanded top end of the burner proper and then downwards into the bottom end
of the said burner, the end of the tube being provided with an orifice or nozzle.
For starting the apparatus I provide below the vaporizer a cup for the reception
of spirit.
The action of the apparatus is as follows:-The petroleum being allowed to
pass into the vaporizer, the spirit in the cup is ignited and will warm the
vaporizer thereby vaporizing the petroleum therein. The vapour evolved passes
to the top of the vaporizer through the tube leading from the same over the
enlarged end of the burner and into the bottom of the same through the orifice
or nozzle at the end of the said tube. Here it mixes with air drawn through
the opening or openings in the bottom of the burner proper and passes up the
same becoming in its passage thoroughly mixed with the air, and the mixture
finally emerges through the metal gauze and is ignited by the flame from the
burning spirit. The heat obtained from the mixture of petroleum vapour and
air heats the tube connecting the vaporizer and the burner proper, which, as
above described, passes around the top of the burner above the gauze and to
enable heat to pass to the vaporizer I provide a conducting mantle or the like
surrounding or placed in the flame.
It will be obvions that with the above construction a constant supply of petroleum
vapour will be delivered from the nozzle into the bottom of the burner proper
without it being necessary to force the petroleum from the reservoir.
For the purpose of wholly or partially extinguishing the flame I provide a
valve in the reservoir adapted to cut off the supply of petroleum or the like to

page_text: the vaporizer or I provide a valve or cock in the tube connecting the vaporizer
with the burner adapted to cut off the supply of vapour to the latter. A shield or
wind guard is advantageously placed around the burner.
The whole is mounted on a suitable stand or casing according to the use for which
the apparatus is intended.

Improvements in and connected with Petroleum and like Burners
for Cooking and other Purposes.
1, ZACHARI GEORGIEVITCH LESSENKO, of Julin near Semenoffsky Gates,
Moscow, in the Empire of Russia, Lieutenant of Reserve, 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 improvements in and connected with burners for
petroleum and like oils which are more especially adapted for use as stoves for
cooking purposes but are also applicable for other heating purposes such as
for rendering mantles incandescent for illuminating purposes.
In such stoves as hitherto constructed the petroleum or the like is usually
fed to the burner by air pressure. This arrangement is attended with various
disadvantages which it is the object of the present invention to obviate by feeding
the petroleum or the like to the burner without pressure.
According to my invention I advantageously provide an oil reservoir of annular,
cylindrical or other suitable form having at the top an opening through which it
can be filled and at the bottom an outlet by which the petroleum or other oil can
escape through a tube to a vertical vaporizer of annular, cylindrical or other
suitable form.
The burner proper consists of a vertical tube having an opening or openings at
the bottom for the entrance of air and expanded or enlarged at the upper end, the
expanded or enlarged upper end being preferably covered with wine gauze.
The said burner is connected with the vaporizer by a tube which issues from
the latter at a point above the level of the oil in the reservoir, passes over the
expanded top end of the burner proper and then downwards into the bottom
end of the said burner, the end of the tube being provided with an orifice or
nozzle.
For starting the apparatus I provide below the vaporizer a cup for the reception
of spirit.
For the purpose of wholly or partially extinguishing the flame I provide a
valve in the reservoir adapted to cut off the supply of petroleum or the like to
the vaporizer or I provide a valve or cock in the tube connecting the vaporizer
with the burner adapted to cut off the supply of vapour to the latter. A shield or
wind guard (ot shewn in the drawing) is advantageously placed around the
burner.
The whole is mounted on a suitable stand or casing according to the use for which
the apparatus is intended.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a vertical section of a stove constructed according to my invention:
Figure 2 is a plan of the same, and,
Figure 3 is a trout elevation drawn to a smaller scale:

I will first describe my invention by reference to Figures 1,
oil reservoir annular in form and 6 is the opening at the top for filling the same;
c is the outlet at the bottom by means of which the oil can escape through the
tube d to the annular vaporizer e.
fis the burner proper having its upper end g enlarged or expauded, the said
enlarged end g being covered with wire gauze h, i is the opening at the bottom of
the said burner f for the entrance of air.
jis the tube issuing from the top of the vaporizer e above the level of the oil in
the reservoir, the said tube then passing over the expanded end g of the burner and
downwards into the bottom of the burner fas shewn, the tube being provided
at its bottom end with the orifice k; ¹ is a hole in the bottom of the burner f for
observing the orifice k.
is the valve or cock in the tube j the said valve being adapted to cut off the
supply of vapour to the burner for partially or wholly extinguishing the flame
of the same; m is the cup for the reception of spirit for the purpose of starting
the apparatus. n is the conducting mantle provided to facilitate the passage of
heat to the vaporizer and to protect the reservoir a from the flame.
0, 0. o are ordinary legs soldered or otherwise attached to the reservoir a for
supporting the apparatus and extended upwards and bent over at o¹ to form a
support for the cooking utensils or the like.
The arrangement shewn in Figures 4 and 5 is substantially the same as that
shewn in Figures 1, 2 and 3 except that the reservoir a and vaporizer e instead of
being annular are made cylindrical and the tube j instead of passing straight
across the enlarged end g of the burner passes over the same in the form of a
circle, as clearly shewn in plan in Figure 5, and then down by the side of the
vaporizer e to the bottom of the burner. In this case the valve in the tube j
leading from the vaporizer e is replaced by the valve p in the reservoir a the said
valve P being actuated by a thumb-screw 9 which passes through the top of the
reservoir a. The conducting mantle also in this modification is replaced by a
conducting bar or strip n¹ whilst the legs o, o are dispensed with, and the burner f
is attached to the vaporizer e by means of a strap r passing around the said
vaporizer e and enclosing the descending portion of the tube j.
The
The action of the apparatus is as follows:-The reservoir a is filled, to a
convenient height, with petroleum or other suitable oil through the orifice b.
valve or cock or the valve p is then opened, and some spirit is poured in the cup m
and ignited. The burning spirit will warm the vaporizer e thereby vaporizing the
petroleum or other oil which has flowed therein from the reservoir through the
tube d. The vaporized petroleum passes (as shewn by the arrows in Figure 1) to
the top of the vaporizer e and through the tube leading from the same, over
the enlarged end 9 of the burner fand thence downwards into the bottom of the
said burner passing through the orifice k of the tube. Here it mixes with air
drawn through the opening i in the bottom of the said burner and passes up the
same becoming in its passage thoroughly mixed with the air, and the mixture
finally emerges through the wire gauze h and is ignited by the flame from the
burning spirit. The heat obtained from the burning mixture of petroleum
vapour and air heats the tube j and the vaporizer e whereby a constant formation
of vapour takes place and the burner is continuously fed without it being necessary
to force oil into the same under pressure.
Among the advantages possessed by my improved burner and stove over those in
general use are the following
1. Practically perfect combustion of the petroleum vapour without light, deposit,
smell or noise.

page_text: 2. Absence of pressure in the reservoir or in the burner thereby dispensing
with the necessity of any arrangement for obtaining such pressure usually necessary
in other burners.
3. The petroleum cannot pass from the reservoir to the tube connecting the
vaporizer and the burner proper as the said tube issues from the vaporizer at a
point above the level of the petroleum in the reservoir.
4. The petroleum vapour Hows through a large opening which does not therefore
get clogged up.
5. Not only petroleum but also benzine and other heavier products of distillation
from naphtha can be used with my burner.
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 petroleum and like burners for cooking and heating purposes the combination
of a reservoir, a vaporizer the bottom of which is in communication with the bottom
of the reservoir, a burner proper having an enlarged or expanded upper end and an
opening or openings for the admission of air at its lower end, a tube or pipe issuing
from the upper end of the vaporizer above the level of the petroleum or other oil
in the reservoir and passing over the expanded or enlarged end of the burner
proper and opening into the lower end of the same, the lower end of the tube or
pipe being provided with an orifice for the escape of the vapor of petroleum or
other oil substantially as, and for the purpose, described.
2. The improved burner or stove hereinbefore described and illustrated in
Figures 1 to 3 of the drawings.
3. The modified construction of my improved burner or stove herein before
described and illustrated in Figures 4 and 5 of the drawings.
