Improvements in Burners for Petroleum and other Vapours.
I, VEUVE LÉON LONGUEMARE (née Amélie Lechesne) of 12 Rue du Buisson
St. Louis, Paris, in the Republic of France, Engineer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to burners for the vapours of petroleum and the like under
pressure for intensely heating the igniters of gas and other explosion engines and
steam generators and for other heating purposes.
According to my invention I combine with the nozzle or chimney of the burner,
a coil of tube or pipe constantly maintained at a high temperature, placed within
or without the said nozzle and through which the petroleum passes and in which it
becomes vaporized before passing to the burner proper whereby subsequent.
accidental extinction is rendered absolutely impossible.
The burner comprises a cast iron support formed by a socket cast in one piece
with a cross shaped piece and a vertical screw-threaded stem. The stem receives
a cup and is screwed or rests on a suitable bracket or support.
To one of the arms of the cross shaped piece is connected by means of a nut
the adjutage with capillary outlet and which communicates with the reservoir in
which the petroleum is compressed. The said arm is perforated and its interior
passage communicates with the coil of tube or pipe one of the ends of which is
brazed or soldered to the said arm. The other end of the coil is brazed or soldered
to another hollow arm placed diametrically opposite the first described arm.
passage in this arm communicates with a central chamber separated from the
outside by a conical valve or burner proper the stem of which is screwed into
the cast iron support.
The
On the outer surface of the conical valve is a number of small slots made in the
direction of generatrices of the cone so as to form channels through which the
petroleum vapours can issue in divergent jets.
The socket of the frame is screw-threaded on its exterior and receives the nozzle
or chimney of copper, brass or other suitable metal. As the jets of petroleum
vapour which issue from the burner proper spread out they come in contact with
the inner surface of the said chimney and when the said vapours are ignited there
issues from the apparatus a flame of great intensity the diameter of which at the
base equals that of the whole chimney.
Holes suitably distributed over the surface of the chimney allow the admission
of air which in conjunction with the air entering through the lower part of the
apparatus, that is to say, between the arms of the cross shaped piece insures a very
active and absolutely perfect combustion.
:
The starting is effected by pouring a small quantity of spirit such as alcohol to
be burned in the cup and then setting light to this liquid. When the apparatus:
has become hot enough the admission valve for the petroleum must be opened,
when the petroleum will gradually reach the capillary adjutage which will project :
it into the coil directly heated by the spirit; the petroleum becomes volatilized in
the coil and passes off in the condition of vapour through the burner proper. The
said vapour is ignited or, rather, the spirit flammes set light to it and thenceforth
the continuous action of the burner is ensured there being no possible risk of

page_text: extinction, the coil in which the petroleum is vaporized being directly heated by
the flame of the burner.
To extinguish the flame it is only necessary to close the petroleum inlet valve.
In some cases the coil through which the petroleum passes before reaching the
burner proper, is placed outside the chimney.
The petroleum delivered through the adjutage with capillary orifice passes
through a lateral chamber into the coil and comes back through a passage into the
burner proper which is in this case formed of a simple adjutage screwed into the
support. The admission of the petroleum into the chamber is controlled by a
conical ended regulating screw valve operated from the outside by turning a milled
head.
On the stem of the support is placed the starting cup and in the support socket
which is screw-threaded, is screwed the cylindrical or conical nozzle or chimney
perforated with air holes suitably distributed over its periphery. Other vertical
holes situated at the base of the socket also serve to admit air.
In the chimney are two crossed arins which are designed to break the flame and
throw it back on to the walls of the chimney.
The starting and extinction are effected in the same way as for the first described
burner. The coil is not directly exposed to the flames of the burner, but as it is
applied to the socket, the heat transmitted is sufficient to ensure the vaporization
of the petroleum.
It will be obvious that where a very high degree of heat is required a number
of my burners can be arranged together on a single support and that they can be
utilized for various purposes such as for heating different kinds of boilers, the
ignition chambers of gasoline and petroleum motors employed in auto-cars, or
distilling apparatus and the like.

Improvements in Burners for Petroleum and other Vapours.
I, VEUVE LÉON LONGUEMARE (née Amélic Lechesne) of 12, Rue du Buisson
St. Louis, Paris, in the Republic of France, Engineer, 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 burners for the vapours of petroleum and the like under
pressure for intensely heating the igniters of gas and other explosion engines and
steam generators and for other heating purposes.
According to my invention I combine with the nozzle or chimney of the burner,
a coil of tube or pipe constantly maintained at a high temperature, placed within
or without the said nozzle and through which the petroleum passes and in which it
becomes vaporized before passing to the burner proper whereby subsequent
accidental extinction is rendered absolutely impossible.
In the drawing I have illustrated two arraugements of my burner, one more
particularly applicable for extensive heating purposes, such as the heating of
steam generators, etc., and the other for heating purposes of less importance, such
as the heating of the iguiters of petroleum or gas engines etc.
Figure 1 of the drawing is a vertical section of the first of the said arrangements
of my burner the coil of tube or pipe being placed within the nozzle or chimney.
Figure 2 is a plan of the burner illustrated in Figure 1:

Referring to Figures 1 and 2 the burner comprises an iron support formed by
a socket a cast in one piece with a cross-shaped piece A and a vertical screw-
threaded stem c. The stem receives a cup d and is screwed or rests on a suitable
bracket or support.
To one of the arms a¹ of the cross-shaped piece is connected by means of a nut d'
the adjutage with capillary outlet and which communicates with the reservoir in
which the petroleum is compressed. The arm a¹ is bored out and its interior
passage f¹ communicates with the coil S of tube or pipe one of the ends s of which
is brazed or soldered to the said arm. The other ends of the coil S is brazed or
soldered to another hollow arm a placed diametrically opposite to the arm a¹.
The passage g in the arm a² communicates with a central chamber h closed by
a conical valvej or burner proper, the stem j¹ of which is screwed into the cast
iron support.
On the outer surface of the conical valve j is a number of small grooves o (six
being shewn in the drawing) made in the direction of generatrices of the cone so as
to form channels through which the petroleum vapours can pass and from which
they issue in divergent jets.
The socket a of the support is screw-threaded on its exterior and receives the
nozzle or chimney B of copper, brass or other suitable metal.

Holes k suitably distributed over the surface of the chimney allow the admission

is ignited or, rather, the spirit flames set light to it, and thenceforth the continuous
action of the burner is ensured, there being no possible risk of extinction, the
coil in which the petroleum is vaporized being directly heated by the flame of
the burner.
To extinguish the flame it is only necessary to close the petroleum inlet valve.
In Figures 4, 5 and 6 I have illustrated a burner of less importance in which the

Tertical holes situated at the base of the socket q also serve to admit air.
In the chimney B₁ are two crossed arms B' which are designed to break the

takes place.
The starting and extinction are effected in the same way as for the first described
burner. The coil S' is not directly exposed to the flames of the burner, but as
it is applied to the socket g, the heat transmitted is sufficient to ensure the
vaporization of the petroleum.
It will be obvious that where a very high degree of heat is required a number of
my burners can be arranged together on a single support and that they can be
utilized for various purposes such as for heating different kinds of boilers, the
ignition chambers of gasoline and petroleum motors employed in auto-cars, or
distilling apparatus and the like.
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 :-
1. A burner for the vapours of petroleum and the like under pressure characterized
by the combination with the nozzle or chimney of a burner of a coil of tube or pipe
adapted to be preliminarily heated to a high degree of temperature by a starting
flame of spirit such as alcohol and then kept at such temperature by the heat from
the burner itself, the petroleum or the like circulating and becoming vaporized in
the said coil before passing to the burner proper in such a manner as to render
subsequent extinction impossible substantially as herein before described.
2. In a burner for the vapours of petroleum and the like under pressure such as
is claimed in Claim 1, the combination with a burner proper in which the vapours
issue in divergent jets, of a nozzle or chimney and a coil of tube or pipe placed
within the said chimney in which circulates the petroleum on its way to the burner
proper substantially as herein before described.
3. In a burner of the kind claimed in Claim 1, the combination with a burner
proper consisting of a simple adjutage of a nozzle or chimney and a coil of tube
or pipe placed outside the said chimney substantially as hereinbefore described.
4. In a burner of the kind claimed in Claim 1, the combination with a burner
proper consisting of a simple adjutage and with a coil of tube or pipe placed
around the nozzle or chimney, of a conical ended regulating screw or valve for
controlling the admission of the petroleum or the like substantially as hereinbefore
described.
5. In a burner of the kind claimed in Claim 1 the combination with a burner
proper and a coil of tube or pipe placed within or without the nozzle or chimney,
of a cup placed beneath the coil and in which spirit, such as alcohol, is burned for
starting the burner substantially as herein before described.
6. The improved burners for petroleum and other vapours hereinbefore
described and illustrated in Figures 1 to 3 and Figures 4 to 6 of the accompanying
drawings.
