Improvements in Liquid Fuel Stoves or Furnaces.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from Pierre Carmien, of Montbéliard (Doubs), Engineer,
and Antoine Yvonnet, of Roanne (Loire), Contractor, both in the Republic of
France) to be as follows:-
The stove or furnace forming the subject of the present invention is applicable
to all kinds of heating apparatus, fixed or portable, and consists of the following
essential parts.
1st. A reservoir containing petroleum or other hydrocarbon, whose vapours are
to be burned in the stove or furnace, properly so called, at a greater or less
distance from the reservoir.
2nd. A stove, furnace or burner, wliose form will vary according to its
applications.
3rd. A special communication, formed of one or several tubes of small diameter,
connecting the reservoir to the stove, furnace or burner.
4th. A vaporizing tube ip which the liquid is vaporized in proportion to
requirements.
6th. A heater transmitting to the vaporizer the amount of hent necessary for
the vaporization of the liquid.
In order that the operation of these various parts may be clearly understood
I will, by way of example, describe the application of the invention to a kituhen
stove represented in the accompanying drawings, in which :—
Fig. is a vertical section, Fig. 2 is a plan and Fig. 3 is an elevation partly in
section, of the stove.
Fig. 4 is a sectional elevation and Fig. 4* is an eud' view showing a method of
connecting a bundle of small tubes forming a communication between the reservoir
and the stove, and
Fig. 5 is a longitudinal section showing the application of the invention to
anothor form of stove or furnace.
The reservoir A, which may be of any suitable form, is placed at a higher level
than the stove, furnace or burner, and at a distance sufficient to prevent all
danger; it communicates with the latter by a tube C having a diameter of about
2 millimeters at the most, and which can be coiled in order to afford sufficient
flexibility in the case of portable apparatus; this tube is united with the reservoir
by a regulating cock or valve B, and is connected at its other ond to the vaporizing
tubo D of larger diameter and in proportion to the size of the furnace. This tubo
surrounds the stove or burner H without touching it; it is provided with spongy
material inside and terminates with a regulating cock or valve M, whose outlet.
orifice, which is very small, opens centrally of the enlarged space or chamber at
one end of the pipe F, which conducts the vapours to the interior of the stove or
furnace, which latter is covered with a perforated plate R. Above this plate is
fixed the heater E consisting of a disc extending, by a band or plate of sufficient
section, to just above the tube D, with which it is soldered or in intimate contact.
On the side of the cock or valve M is arrauged another cock or valve V, see
Fig. 3, closing a small orifice which forms a communication between the tube D
and a small cup U used when lighting the apparatus.
-

page_text: The apparatus operates in the following manner.
The reservoir being furnished with combustible liquid, the cock or valve B is
opened, the liquid then flows slowly through the small tube C and saturates the
spongy material of the vaporizer D and reaches the cock or valve M. By slightly
unscrewing the cock or valve V, a few drops of the liquid will be allowed to enter
the cup U, this is then lighted, the vaporizer D will then commence to work, the
valve or cock M is then opened and the combustible vapours, mixed with air
drawn into the tube F through the orifices a a, will fill the stove or furnace and
pass out of the same through the holes in the plate R. There they will be lighted
by the flame of the lighter U, which spreads out below the beater E. From this
momneut the heat of the stove or furnace is transmitted regularly to the tube D by
the beater E in such manner as to continue the vaporization of the liquid which
continues to arrive from the reservoir.
The intensity of the flame will be regulated by opening more or less the cock or
valve M and, if required, the cock or valve B of the reservoir.
A single reservoir may be used to supply a number of stoves or furnaces, and in
order to avoid the use of a reservoir of large dimensions, it can be supplied with
liquid from a suitable cask or container placed at a higher level. This supply can
be effected by means of float valves of any suitable construction, maintaining a
constant level in the reservoir, which can consequently contain a very small
quantity of liquid and ensure notwithstanding the regular supply of any required
number of burners, stoves or furnaces.
When the nearly capillary tube conducting the liquid to the burners, stoves or
furnaces, is not sufficient, the diameter of the same will not be increased, but
several of such tubes will be connected together, either by enclosing them within a
flexible sheath or covering, or by twisting them together as a cable.
To enable these bundles of tubes to be readily connected with the apparatus,
their ends are brought together and soldered within a sleeve G, see Fig. 4, which
Jatter carries the coupling.
For beating ovens, encampment pots, and for the different heating of industrial
apparatus, the previously described parts will be changed in form but will always
have the same functions. Fig. 6 shows an example. In this modification the
burner consists of one or several tubes H whose form and dimensions will be varied
according to the application.
The liquid conveyed from the reservoir by the tube or bundle of tubes C,
reaches the vaporizer D containing spongy material, and is vaporized by the heat
of the beater E exposed to the flame of the burner, its vapors enter, through the
cock or valve M, into the tube F, where they are mixed with air drawn in through
the orifices a and are burned at the outlet of the holes formed in the burner or
burners.
It will readily be understood that by employing burners of suitable form, and
by surrounding them with appropriate envelopes or casings, there might be formed
kitchen stoves with ovens, roasters, boilers, &c., warming apparatus for apartments,
and in fact all the needs of domestic and industrial heating can be supplied.
By providing the cock or valve M, Figs. 1, 2 and 5, with a branch closed by a
cock or valve, a portion of the vapors generated in the vaporizer can be conducted
to a burner serving for the illumination of the apparatus.

I, BENJAMIN Joseph Barnard MILLS, of 23 Southampton Buildings in the
City and County of London, Patent Agent, 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 :—
The stove or furnace forming the subject of this invention is applicablo to all
kinds of heating apparatus, fixed or portable, and consists of the following essential'
parts:-
1st. A reservoir containing petroleum or other hydrocarbon whose vapoura are
to be burned in the stove or furnace, properly so called, at a greater or less distance
from the reservoir.
2nd. A stove or burner whose form will vary according to its applications.
3rd. A special communication formed of one or several tubes of small diameter
connecting the reservoir to the stove, furnace or burner.
4th. A vaporising tube in which the liquid is vaporised in proportion to
requirements.
6th. A beater transmitting to the vaporiser the amount of heat necessary for the
vaporisation of the liquid.
In order that the operation of these various parts may be clearly understood,
I will by way of example, describe the application of the invention to a kitchen
stove represented in the accompanying drawings, upon which,
Figure 1 is a vertical section of the reservoir and stove. Figuro 2 being a plan.
and Figure 3 an elevation partly in section, of the above.
Figure 4 is a sectional elevation and Figure 4ª is an end view showing a method
of connecting a bundle of small tubes forming a communication between the
reservoir and the stove, and
Figure 5 is a longitudinal section showing the application of the invention to
another form of stove or furnace.
The reservoir A which may be of any suitable form is placed at a higher level
than the store, furnace or burner and at a distance sufficient to prevent all danger;
it communicates with the latter by a tube C, of a diameter of about two millimètres
and which can be coiled in order to afford sufficient flexibility in the case of
portable apparatus; this tube is connected with the reservoir by a regulating cook
or valve B and its other end communicates with the vaporizing tube D. This
tube D is of larger diametor and varies in proportion to the size of the furnace.
It surrounds part of the stove or burner H and it is provided with spongy material.
inside and terminates in a regulating cock or valve M whose outlet orifice, which
is very small, opens into the enlarged chamber at one end of the pipe F which.
conducts the vapours to the interior of the stove or furnace, this latter being
provided with a perforated plate R. Above this plate is arranged a heater E
consisting of a disc which is connected by a band or plate to the upper part of the-
tube D and to which it is soldered or otherwise attached.
On the side of the cock or valvo M is arranged another cock or valve V
(see Figure 3) closing a small orifice which forms a communication between the
tube D and a small cup U used when lighting the apparatus,
•
The apparatus operates in the following manner. The reservoir being furnished
with combustible liquid, the cock or valve B is opened and the liquid then flows.
slowly through the small tube C and saturates the spongy material of the
vaporizer D, and reaches the cock or valve M. By slightly unscrewing the
cock V, a few drops of the liquid will be allowed to enter the cup ; this is then.
lighted and the vaporizer D will commence to work. The valve M is then opened
and the combustible vapours mixed with air drawn into the tube F through the

page_text: orifices a a, will fill the stove or furnace and pass out of the same through the
holes in the plate R. There they will be lighted by the flame of the lighter U,
which spreads out below the heater E. From this moment the heat of the stove
or furnace is transmitted regularly to the tube D by the heater E, in such manner
as to continue the vaporization of the liquid drawn from the reservoir.
The intensity of the flame will be regulated by opening more or less the cock or
valve M, and if required, the cook or valve B of the reservoir. A singlo reservoir
may be used to supply a number of stoves or furnaces and in order to avoid the
use of a reservoir of large dimensions, it can be supplied with liquid from a suitable.
cask or container placed at a higher level. This supply can be effected by menos
of a float, valves of any suitable construction or other device for maintaining a
constant level in the reservoir which can thus contain a very small quantity of
liquid but nevertheless ensure a regular supply to any number of burners, stoves or
furnaces. When the capacity of the capillary tube leading to the burners stoves
or furnaces is not sufficient I do not increase the diameter of the same but I connect
several of such tubes together either by enclosing them within a flexible sheath or
covering or by twisting them together as in a cable. To enable these bundles
of tubes to be readily connected with the apparatus, their ends are brought
together and soldered within a sleeve G, see Figure 4, which latter carries the
coupling.
For heating ovens, cauldrons and the like, and for heating various industrial
apparatus, the previously described paris may be changed in form but work in
the same or a similar manuor. Figure 5 shows a modified arrangement. In this
modification the burners consist of one or more tubes H, the form and dimensions
of which may be varied according to circumstances.
The liquid conveyed from the reservoir by the tube or bundle of tubes C,
reaches the vaporizer D which contains spongy material and is vaporized by the
heater E exposed to the flame of the burners; its vapours pass through the cock
or valve M into the tube F, where they are mixed with air drawn in through the
orifices a and are burned at the outlet of the holes formed in the burner or
burners.
It will readily be understood that by employing burners of suitable form and by
Burrounding them with appropriate casings or envelopes, I can construct kitchen
stoves with ovens, roasters, boilers etc.: worming apparatus for apartments and in
fact, every need of domestic and industrial heating can be supplied.
By providing the cock or valve M, Figures 1, 2 and 5, with a branch closed by
a cock or valve, a portion of the vapours generated in the vaporizer can be
conducted to a burner serving for the illumination of the apparatus.”
Having now particularly described and ascertained the nature of this said
invention and in what mannor the same is to be performed, (as communicated
to me by my foreign correspondents) I declare that what I claim is :-
1. A heating stove or furnace for burning hydrocarbon vapours, constructed,
combined and arranged substantially as described and illustrated on Figures 1, 2
and 3 of the accompanying sheet of drawings.
2. The combination of the tubes C and sleeve G for supplying petroloum or
other hydrocarbon from a single reservoir, to a number of stoves, as described aud
illustrated on Figures 4 and 4ª.
3. The arrangement of a stove comprising one or more tubes H, for the purposes
and as described and illustrated on Figure 5 of the annexed drawings.
