Improvements in Lamp Burners for Burning Petroleum or other
Mineral Oils.
I, LEON AUBOUT of 28 Rue Debelleyme, Paris, France, Mechanician, do, hereby
declare the nature of this invention to be as follows:-
:-
My invention relates to that class of lamps in which petroleum or other mineral oils
are used as illuminants, which in the ordinary way become rapidly heated by the heat
generated in the burner, which heat is communicated to the reservoir of the lamp so
that the temperature of the liquid contained therein is considerably increased, and to
such an extent that the volatile inflammable gases contained in the oil are evolved,
thereby rendering the lamp extremely dangerous and frequently causing serious
accidents.
My invention consists in providing means whereby these inconveniences and
dangers are obviated which I effect by the special construction of my improved
burner and the arrangement of the currents of air which check the communication of
the heat of the burner to the reservoir of the lamp, so that the liquid contained
in the said reservoir remains cool, and in consequence no inflammable gases are
evolved.
My burner is made in such a manner that it can be fixed to any ordinary lamp
either by a screw, bayonet joint, or other convenient method.
In order to carry my invention into effect, upon the mounting having the screw,
bayonet joint, or other suitable attachment to fix the burner to the reservoir of the
lamp, a plate is attached upon which are mounted two segmental tubes concentrically
one within the other so as to form a segmental annular space within which the wick
is carried. At the side of the wick tubes may be arranged the milled drum or collar
for regulating the wick. The wick tubes are surrounded by a second tube likewise
fixed upon the plate and concentric therewith and is supported by feet which, leave
openings between them for the passage of the air currents outside the wick. The
space through the segmental wick tubes, serves as a passage for the central current
of air.
This second or air tube rises above the lower wick tube and serves to maintain by
means of three or more supports an upper annular wick tube having the form of a
truncated cone. This upper wick tube is placed slightly above the lower wick tube
with which it is concentric, and a space is maintained between the said higher wick
tube, which is the burner proper, and the lower portion of the wick tube which is
attached to the, reservoir.
Thus metallic connection is broken between the upper and lower wick tubes, the
upper part of the burner being connected by two or more wings to the lower external
air tube which again is attached to the reservoir only by feet, and is surrounded
by the cold inlet air currents. This arrangement practically prevents any com-
munication of heat to the reservoir from the burner. The glass chimney holder may
be fixed to a groove on the second tube, or in any other equivalent manner, and
the gallery for the removable globe may be supported on the cover of the reservoir
which has a projecting ring surrounding by its upper part the glass chimney holder
as a socket.
The wick is entered into the lower segmental tube but emerges in circular form at
the top of the upper conical tube so as to present a continuous annular wick.
I may use in place of the milled drum for the wick regulation two or more pinions
having serrations on the edge, or any other equivalent form of mechanism may be
emploved for regulating the wick.

page_text: This burner may be constructed of tin, brass, or any other suitable material and
may be of round, oval, or any other convenient form.

COMPLETE SPECIFICATION.
Improvements in Lamp Burners for Burning Petroleum or other
Mineral Oils.
I, LEON AUBOUT, of 28 Rue Debelleyne, Paris, France, Mechanician, 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 that class of lamps in which petroleum, or other mineral
oils are used as illuminants, which in the general way become rapidly heated by the
heat generated in the burner, which heat is communicated to the reservoir of the lamp
so that the temperature of the liquid contained therein is considerably increased and
to such an extent that the inflammable gases contained in the oil are evolved, thereby
rendering the lamp extremely dangerous and frequently causing serious accidents.
My invention consists in providing means whereby these inconveniences are
obviated, which I effect by the special construction of my improved burner, and the
arrangement of the currents of air which check the communication of the heat of the
burner to the reservoir of the lamp so that the liquid contained in the said reservoir
remains cool and in consequence no inflammable gases are evolved.
In order that my invention may be the better understood I now proceed to describe
the same in relation to the drawings hereunto annexed, reference being had to the
letters and figures marked thereon. Like letters refer to like parts thoughout the
drawings.
Fig. 1 shows in sectional elevation my improved burner attached to any ordinary
lamp.
Fig. 2. is a horizontal section following the lines 1 and 2 of Fig. 1.
Fig. 3. is a sectional plan of the upper part of the burner following the lines 2
and 3.
Fig. 4. is a plan of the central tube on the upper part of the burner.
My burner is made in such a manner that it can be fixed to any ordinary lamp
either by a screw, bayonet joint or other convenient method.
As seen in Fig. 1 upon the mounting for fixing the burner to the reservoir a of
the lamp I fix a plate A upon which are mounted two segmental tubes concentrically
one within the other so as to form the segmental aunular tube within which the
wick is carried.
At the side of this tube the milled drum, or collar for regulating the height of
the wick is situated.
The annular wick tubes are surrounded by a second tube C likewise fixed upon
the plate A concentric therewith and supported by feet d, which leave openings
between them for the passage of the air current outside the wick.
The space through the centre of the segmental wick tubes serves as a passage for
the central current of air.
The tube C, rises upon the lower wick tube B, and serves to maintain by means
of three or more supports e an upper annular wick tube D, having the form of a
truncated cone.
Thus the upper wick tube D, is placed slightly above the lower wick tube B with
which it is concentric, and a space is maintained between the said upper wick tube D,
which is the burner proper, and the lower portion of the wick tube B, which is
attached to the reservoir.

page_text: This metallic connection is broken between the upper and lower wick tubes the
upper part of the burner tube being connected by the wings e, to the lower air
tube C, which again is attached to the reservoir only by feet d, and is surrounded by
the cold inlet air currents. This arrangement practically prevents any communica-
tion of heat to the reservoir from the burner.
The glass chimney holder is fixed to a groove on the tube C, or in any other
equivalent manner and the gallery G is provided to carry a removable globe and is
supported on the cover F, of the reservoir which has a projecting ring surrounding
by its upper part the chimney holder as a socket.
The distance between the lower wick tube B, and the conical tube D, depends
upon the diameter of the burner.
This tube D, is formed of two conical tubes bound together by a triangular piece E,
the latter being of the same thickness as the wick.
This piece may be fixed by means of solder, rivets, or by any other equivalent
method.
The tube D, is fixed on the tube C, by three or more supports e, according to the
diameter of the burner.
They can be fixed by means of solder rivets, or by a ring provided with a screw
thread, in which case it can be taken to pieces with great facility.
The milled drum b which regulates the height of the wick I may make of one
piece baving a periphery similar to the curvature of the tube to which it is fixed, or
equivalently it can be made of two pinions mounted upon a spindle, and working
through suitable openings made in the tube for the purpose.
The flat wick is entered into the annular tube B, and emerges in a circular form at
the top of the upper conical tube D, in such a manner as to present a continuous
annular wick.
The burner may be constructed in tin, brass, or other stiff metal, and may be of
round, oval, or any other convenient form, and can be applied to all kinds of lamps
burning petroleum or other mineral oils.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The construction and arrangement of a burner for lamps burning petroleum
or other mineral oil in such a manner that the upper part of the wick carrier is
isolated from the lower part of the same, the upper part only communicating with
the oil reservoir by an external tube and metal supports, around which currents of
air flow, so as to prevent the heat of the burner being transmitted to the oil
reservoir substantially as described.
