Combustible Liquids.
Wo JULES DHEYNE, of Schaerbeck, Mechanie Comte VITOLD DE NYDPRÜCK and
FREDERIO DE LA HAULT, Gentlemen both care of Messieurs E. Bede & Cie. 37 Rue
Philippe-le-Bon Brussels all in the Kingdom of Belgium do hereby declare the nature
of this invention to be as follows
This invention relates to apparatus for generating gas or vapour from combustible
liquids and it consists of apparatus composed of a tank, charged with naphtha,
petroleum, or the like which flows off through a pipe ending in a coil, and the end of
which is bent back in such a manner as to throw into the axis of said coil the gas
escaping from said end. The coil is in contact with a metal surface or tube and
placed above a vessel or tray within which is burnt, for the purpose of starting the
apparatus, any highly combustible liquid. The gas created by the heat of this
combustion is ignited at the end of the coil and the flame heats the latter up to
a temperature which can be regulated by means of a cock, thus varying the quantity
of gas escaping from the coil.
The invention embraces the combination with the coil tank tube and tray of a
platina vessel arranged at the bottom of the motor cylinder and a second coil starting
likewise from the liquid tank which is supplied with compressed air by means of a
pump communicating with the motor cylinder.
Also the combination of a coil, a pipe, tube tray, and a liquid tank with an
elastic plate giving a pressure to the contents of the tank which can be regulated, and
a cock for regulating the communication from said tank to the coil.
Also the substitution of a flat spiral for the coil and tube, combined with a wire
gauze or perforated metal sheet, the liquid tank being placed at a higher level to and
communicating with the said flai spiral one end of which is extended to a tray
arranged at the lower part of the apparatus.

Improved Apparatus for Generating Gas or Vapour from
Combustible Liquids.
We, JULES DHEYNE of Schaerbeck Comte VITOLD DE NYDPRÜCK and FREDERIC DE
LA HAULT both of Brussels care of Messrs. E. Bede & Cie. 37 Rue Phillippe le Bon
all in the Kingdom of Belgium do hereby declare the nature of our said Invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The apparatus for generating gas or vapour from combustible liquids according to
this Invention is provided with a tank or receptacle from which the liquid is caused
to flow through a pipe provided with a regulating valve to a coil or worm in which it
is converted into gas or vapour as hereinafter described.
The coil is arranged in contact with a metal surface or tube and placed above a
trough or vessel within which is burnt for the purpose of starting the apparatus any
suitable combustible liquid. The gas or vapour generated by the heat of this com-
bustion is ignited at the end of the pipe forming the coil and the flame heats the

page_text: latter up to a temperature which can be regulated by means of a cock or valve
controlling the escape of gas from the coil. The rate at which the vapour is generated
being naturally dependent on this temperature the action is automatically regulated
the quantity of vapour produced being always equal to the quantity consumed.
The invention embraces the combination with the said generating coil tank tube
and trough of a platinum vessel acting as an igniter arranged at the end of a cylinder
of a vapour engine or motor and a second coil communicating with the same liquid
tank which is supplied with compressed air by means of a pump or by the action of
the engine piston. Also the combination of the coil tube and trough with a liquid
tank provided with an elastic plate for applying adjustable pressure to the contents of
the tank and a cock for regulating the supply of liquid from the said tank to the coil.
This arrangement is suitable for generating gas or vapour for lamps employed in
soldering or enamelling operations.
According to another arrangement a flat spiral is substituted for the coil and tube
being combined with a wire gauze or perforated metal sheet the liquid tank being
placed at a higher level to and communicating with the said spiral one end of the
pipe forming the spiral being extended downwards in the direction of a trough
arranged at the lower part of the apparatus. This arrangement is suitable for
generating gas or vapour for cooking or other like heating purposes.
And in order that our said Invention may be fully understood we shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures in the annexed Drawings the same letters of reference indicating corresponding
parts in all the figures.
Figure 1 illustrates in elevation an arrangement of apparatus according to this
invention as employed for generating gas or vapour for motive power engines
Figure 1 illustrates this arrangement in horizontal section.
In this arrangement the apparatus is provided with a hollow metal cylinder or
tube A around which is coiled a tube or pipe B of relatively small diameter the
extremity C of which is bent in such a manner as to deliver a jet of vapour in the
direction of the axis of the tube A. The other extremity of the pipe B descends into
the liquid occupying part of a tank or receptacle E supplied with compressed air from
a pump cylinder or compressor in communication with this receptacle.
In the interior of the tube A there is a platinum cap or vessel D connected
with the head or end of the engine cylinder and at the end of the tube A there is a
second coil or worm F formed by a pipe one extremity of which leads to the
mixing chamber of the engine cylinder at m the other extremity being connected
with a force pump P the suction pipe of which communicates with the liquid in
the receptacle E.
In order that the coil F may not be exposed to excessive pressure this coil may
be connected with a chamber G' indicated in dotted lines in- figure-l the end of
the coil being open at d and the oil being injected into the coil solely through a
pipe e. The vapour generated in the coil enters the chamber G' which constitutes a
species of magazine or reservoir of vapour which is drawn downwards through the
coil by the action of the engine.
Each time that a fresh quantity of petroleum is injected into the coil at c
through the pipe e it is converted into vapour for the supply of the engine. The
opening d in the coil combined with the employment of a magazine of vapour prevents
any excess of pressure in the interior of the coil.
Figures 2 and 2ª illustrate in elevation and plan respectively the plan being
partly in section an arrangement in which the tube A and coil B. are placed
in a vertical position instead of being in the horizontal position represented in
Figures 1 and 1º.
A vessel or tray G Figure 1 or an annular trough G Figure 2' is provided' for
the reception of spirit or other combustible which is burned for starting the apparatus
by heating the tube A and the coils B and F Figures 1 and 2. Afterwards a

page_text: cock in the pipe supplying the coil B being opened a certain limited quantity of
liquid is forced into the said coil B by the action of the compressed air in the
receptacle E and being converted into vapour in the coil B is ignited at C by the
flame of the spirit. The jet of vapour thus ignited escapes with sufficient force to
draw into the tube A with the flame the quantity of air required for perfect com-
bustion and by the action of the flame produced the coil F is quickly heated to
redness and the platinum cap or igniting tube D is heated to a white heat.
A cock I in the pipe supplying the pump P is then opened and the liquid
forced from the receptacle E into the coil F is converted into vapour which mixes
with the air compressed in the distribution or valve chest of the engine the mixture
thus formed being admitted to the engine cylinder where it is ignited by contact with
the platinum cap D.
It is evident that the force pump P may be dispensed with by causing one end of
the coiled pipe to communicate directly with the liquid in the receptacle E. In
this case a retaining valve must be placed in the pipe in order to prevent reflux of
liquid into the receptacle.
In engines in which the compression of the air is effected in the cylinder and not
in a separate compresser the pressure in the receptacle E may be produced either by
means of a pipe branching off from the cylinder and provided with a valve arranged
to open during the compression only or by means of a small air pump.
Figure 3 of the accompanying drawings illustrates in vertical section an example
of an apparatus for generating vapour according to this Invention applied to lamps
such as are employed in soldering and enamelling operations.
The liquid is contained in a chamber or receptacle E formed by a head K
constructed with an elastic or flexible plate 1. applying mechanical pressure on the
liquid contained in the said receptacle. This plate L. is supported between two sheet
metal plates and o and is acted on by a helical spring placed in the foot or base of
the lamp. The tension of this spring can be regulated by means of a lever and
screw . The head K is perforated with a hole e through which the petroleuin or
other liquid is introduced. This hole can be closed by a stopper or cap and the
chamber E communicates through a cock H with a coil or worm B surrounding a
tube A the extremity of the pipe forming the said coil being arranged as indicated
at e so as to project inwardly in the direction of the axis of the tube A. The jet
delivered from the extremity of this pipe is regulated by a needle valve g which can, be
adjusted by a screw provided with a milled head. A. trough G is provided underneath
the coil B for starting the lamp the said trough being attached to the handle V by
which the lamp is held. The elastic plate Lust be composed of material not liable
to be affected by contact with the liquid and may be composed of dermatine for
example or of a thin metal plate corrugated in the same way as the diaphragm of an
aneroid. In place of this plate a piston such as is employed in a moderator lamp and
acted on in like manner by a spring may be employed. In this case the arrangement.
for regulating the flow of the liquid may also be similar to that employed in these
lamps.
In using this apparatus the oil chamber or receptacle E is charged with the
petroleum or like liquid the plate L being first drawn down by means of the screw r
and the lever Q which acts on a pin Qin the rod extending from the plate L and
encircled by the spring p. When the receptacle has thus been completely filled the
stopper is screwed on and a small quantity of spirit is poured into the trough G
and ignited. Directly the coil B and tube A are sufficiently heated the cock H is
opened and the vapour escaping at the end of the coiled pipe is ignited. The
lamp. is then ready for action a jet of flame being projected from the end of the
tube A. The evaporation naturally continues to take place in the interior of the
coil and by means of the screw r lever Q pin Q and spring p the requisite constant
pressure is maintained on the contents of the receptacle E.
The intensity of the flame may be regulated either by a cock or by means of the
cone or needle valve in the part c of the tube,
.

page_text: Figure of the accompanying drawings illustrates in section an apparatus for
generating gas or vapour for cooking or for laboratory operations for example.
This apparatus is supplied with liquid from an elevated tank E provided with a
float to indicate when it requires replenishing. The flow of liquid is regulated by a
cock H the cylindrical coil of the arrangements herein before described is replaced by
a flat spiral B formed by a pipe which is extended downwards in a suction or draught
chamber and is bent upwards at its extremity C situated above a cup or trough G
containing inflammable liquid employed for starting the evaporation. In place of the
tube or cylinder supporting the coil in the other arrangements a sheet of wire gauze
or the like A is placed in the spiral so as to break up the flame and by its contact
with the spiral retains the beat required for the evaporation. The wire gauze may be
corrugated or it may be replaced by a perforated metal plate and the gauze or the
plate may be placed either over or under the spiral.
