page_text: I, ADAM WEINGOERTENER, of Rue Amelot, Paris, in the Republic of France,
Engineer, do hereby the nature of this invention to be as follows:-
-
This invention relates to improvements in spirit stoves as hereinafter
described.
My improved stove is that of the type in which, in order to effect ignition,
alcohol is heated which, transmitting its heat to alcohol placed in an auxiliary
vessel, vaporises this latter, the vapours produced being ignited upon leaving
the vessel, in such a manner as to produce the heating flame. It presents the
great advantage over other stoves of the kind at present in use of entirely
obviating all danger of fire, because if the stove is inadvertently upset, the
alcohol which has been ignited cannot spread.
The apparatus consists essentially of an inner vessel provided, upon one of its
sides, with a rack which may be acted upon by means of the toothed wheel
arranged at the extremity of the rod which is provided with a milled knob.
The inner vessel is completely open at its upper portion at its lower portion it
is provided with apertures which establish communication between the inner
vessel and the annular or outer vessel. At its upper portion the wall of the
inner vessel comes in contact with the wall of the outer vessel. This latter
is provided with a crown of small apertures.
It will be seen from the above that according to the height of the inner vessel
the apertures will be either closed by the upper portion of the wall of the inner
vessel or not.
Within the outer vessel is provided a circular wick and within the inner
vessel is provided a solid wick which occupies almost the whole volume of the.
said vessel. This wick constitutes the essential feature of my invention, as it
is this wick which, becoming impregnated with the alcohol which is poured
into the vessel, entirely obviates all danger of fire should the stove be upset.
The stove acts in the following manner :,
Through the aperture, which is normally closed by a plug, the wick placed
within the vessel is impregnated with alcohol. This having been affected,
alcohol is also introduced at the upper portion of the inner vessel in such a
manner as to completely impregnate the solid wick arranged within this vessel.
The inner vessel is then completely lowered in such a manner that the apertures
are closed by the upper wall of the said vessel; thereupon the wick placed in
the vessel is ignited. The heat produced by this flame heats the alcohol con-
tained in the vessel: this latter becomes vaporised, and if, after a certain
interval has elapsed, the inner vessel is raised in such a manner as to establish
communication between the outer vessel and the apertures, the alcohol vapours
issuing through those apertures will produce a crown of very intense flame.
When it is desired to extinguish the stove it is only necessary to place the lid
upon the apparatus.
The filling aperture may be replaced by a vertical tube fixed in any suitable
manner to the lower portion of the stove and provided at its lower part with

page_text: apertures through which the alcohol which has been introduced into the tube,
may flow into the outer vessel, and thence into the inner vessel. This tube when
it is not utilized for filling the stove is closed by a suitable plug: Above the
wick placed in the vessel I arranges a metallic gauze.
What has hitherto been stated applies to moderator stoves, that is to say,
stoves comprising a rack and pinion enabling the flame to be regulated. These
improvements may, however, without any modification, be applied to stoves
not provided with a regulator: in this case it is obvious that the vessel which,
in the arrangement previously described was movable, becomes fixed. It will
then be fixed to the vessel in such a manner that the apertures may invariably
be in communication with the atmosphere. This being so, immediately the
vaporised alcohol issues through the apertures, it becomes ignited in contact with
the igniting flame of the vessel.

I, ADAM WEINGOERTENER, of Rue Amelot, 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:-
This invention relates to improvements in spirit stores as hereinafter
described.
My improved stove is of that type in which, in order to effect ignition,
alcohol is heated, which, transmitting its heat to alcohol placed in an auxiliary
vessel, vaporises this latter, the vapours produced being ignited upon leaving
the vessel, in such a manner as to produce the heating flame. It presents the
great advantage over other stoves of the kind at present in use of entirely
obviating all danger of fire, because if the stove is inadvertently upset, the
alcohol which has been ignited cannot spread.
In order that my invention may be readily and clearly understood, I have
represented in the accompanying drawings by way of example, a spirit stove
constructed in accordance with my invention.
Figure 1 is a vertical section through such a stove.
Figure 2 is a plan view of the same.
Figure represents the lid of the apparatus, and
Figures 4 and 5 relate to a modification of the apparatus.
The apparatus consists essentially of an inner vessel a provided, upon one of
its sides, with a rack b which may be acted upon by means of the toothed wheel c
arranged at the extremity of the rod which is provided with a milled knob c.
The inner vessel a is completely open at its upper portion; the lower portion
thereof being provided with apertures f which establish communication between
the inner vessel a and the annular or outer vessel g. At its upper portion, the
wall of the inner vessel a comes in contact with the wall of the outer vessel g.
This latter is provided at its top with a number of small apertures h.
It will be seen from the above that according to the height of the inner vessel w
the apertures will be either closed by the upper portion of the wall of the inner
vessel or not.
Within the outer vessel is provided a circular wick and within the inner

page_text: vessel a is provided a solid wick which occupies almost the whole volume of the
said vessel. This wick constitutes the essential feature of my invention, as it is
this wick which, becoming impregnated with the alcohol which is poured into
the vessel a, entirely obviates all danger of fire should the stove be upset.
The stove acts in the following manner:
Through the aperture i, which is normally closed by a plug, the wick placed
within the vessel is impregnated with alcohol. This having been effected,
alcohol is also introduced at the upper portion of the inner vessel a in such a
manner as to completely impregnate the solid wick arranged therein. The
inner vessel a is then completely lowered, in such a manner, that the apertures h
are closed by the upper wall of the said vessel thereupon the wick placed in the
vessel a is ignited. The heat produced by this flame heats the alcohol contained
in the vessel g thus vaporising it and if, after a certain interval has elapsed,
the inner vessel is raised in such a manner as to establish communication
between the outer vessel g and the apertures h, the alcohol vapours issuing
through these apertures will produce a flame of very intense heat. When it is
desired to extinguish the stove, it is only necessary to place the lid upon the
apparatus.
j
In the modification indicated in Figures 4 and 5 the filling aperture i may
be replaced by a vertical tube fixed in any suitable manner to the lower portion
of the stove, and provided at its lower part with apertures, through which the
alcohol which has been introduced into the tube, may flow into the outer vessel g,
and thence into the inner vessel a. This tube when it is not utilised for filling
the stove, is closed by a suitable plug 7. Above the wick placed in the vessel a,
I arrange a metallic gauze m.
The above description applies more particularly to stoves of the moderator
type, that is to say, stoves comprising a rack and pinion enabling the flame to be
regulated. My invention may, however, without any modification, be adapted
to stoves not provided with a regulator; in this case it is obvious that the vessel a
which, in the arrangement previously described was movable, becomes fixed.
It will then be fixed to the vessel g, in such a manner that the apertures h may
invariably be in communication with the atmosphere. This being so, immedi-
ately the vaporised alcohol issues through the apertures h, it becomes ignited in
contact with the igniting flame of the vessel a.
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: -
A spirit stove constructed with two parts which are arranged in such a manner
that the igniting flame produced in one of them, vaporises the alcohol contained
in the other, for the purpose of producing the heating flame, the said stove being
specially characterised by wicks or other substances capable of becoming impreg
nated with alcohol, one of them being placed within the igniting vessel, and the
other within the vessel for vaporising the alcohol, with the object of obviating
all danger of fire in the event of the stove becoming upset; the vaporisation
vessel being provided, for the purpose of filling, either with an aperture adapted
to be normally closed by means of a stopper, or with a tube completely traversing
the central ignition vessel and communicating with the vaporisation vessel by
means of small apertures, substantially as herein described and illustrated in the
accompanying drawings.
