Improvements in Heating Stoves for Use with Paraffin Oil and
the like.
I, JACQUES AIME VAGNER, of 42 Boulevard Magenta, Paris, in the Republic
of France, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention for improvements in heating stoves for use with paraffin oil and
the like has for its object to construct a strong efficient and simple stove of small
weight, not liable to get out of order and which can be stored when not in use in a
small space.
In a stove constructed according to this invention, the upper or cooking gallery
designed to receive the articles to be heated is secured to the upper end of corner
pieces carried at their lower ends by the upper ends of standards supported on a
base plate on which slides the oil reservoir with its burners. The chimney gallery
designed to support the chimney is also secured to the upper ends of the standards.
Preferably the corner pieces have three sides to ensure strength and the standards
are flat plates. In a slightly modified arrangement the cooking gallery is attached
to the corner pieces by a metallic band on which it fits tightly or is otherwise
secured. The standards and corner pieces may be made in one piece.
The cooking gallery is provided with two sliding or hinged extensions adapted
to be extended outwards or to be folded or slid on the gallery itself without
taking up room.
A heat distributor is mounted at one side loosely so as to slide thereon on a
spindle fixed at one side of the cooking gallery and rests on the cooking gallery.
The changes in the distribution of heat are effected by sliding the distributor
over the flame and distribute the heat equally to both sides or more to one side
according to its position. If not desired to change the distribution, the distributor
is fixed at the desired part of the spindle.
In order to prevent the wicks of the stove being turned up too high, a stop is
arranged in the path of an arm adjustably fixed on the burner spindle and in a
duplex burner having the burners geared together one spindle may form a stop for
an arm adjustably secured to the other spindle or to the gear wheel on it.
In order to give an oil heating stove the appearance of an ordinary fire, the
metallic chimney is provided with an opening or openings covered by mica or
similar plates and small bars having holes in them are arranged across the chimney
opposite the opening. Tufts of asbestos are inserted in the holes and secured by
pinching up the holes or the asbestos may be secured between two bars clamped
together. The bars being small do not conduct much heat to the framework.and
thus to the burners.

page_text: The heating stove is provided with an upper chamber connected to the chimney
by a metallic neck piece, and so arranged that the gases pass up the centre and
sides to the top and down a flue arranged on one side to a horizontal pipe having a
comparatively small outlet at its end and an opening underneath so that the
draught is practically the same whether connected to a chimney or placed in an
open room and in the former case will not be affected by down draughts.

COMPLETE SPECIFICATION.
Improvements in Heating Stoves for Use with Paraffin Oil and
the like.
I JACQUES AIME VAGNER, of 42 Boulevard Magenta, 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 for improvements in heating stoves for use with paraffin oil and
the like has for its object to construct a strong efficient and simple store of
small weight not liable to get out of order and which can be stored when not in use
in a small space.
In a stove constructed according to this invention; the upper or cooking gallery
designed to receive the articles to be heated is secured to the upper end of corner
pieces carried at their lower ends by the upper ends of standards supported on a
base plate on which slides the oil reservoir with its burners. The chimney gallery
designed to support the chimney is also secured to the upper ends of the standards.
Preferably the corner pieces have three sides to ensure strength and the standards
are flat plates. In a slightly modified arrangement the cooking gallery is attached
to the corner pieces by a metallic band on which it fits tightly or is otherwise
secured. The standards and corner, pieces may be made in one piece.
The cooking gallery is provided with two sliding or hinged extensions adapted
to be extended outwards or to be folded or slid on the gallery itself without taking
up room.
A heat distributor is mounted at one side loosely so as to slide thereon on a
spindle fixed at one side of the cooking gallery and rests at its other side on the
cooking gallery. The changes in the distribution of heat are effected by sliding
the distributor over the flame and distribute the heat equally to both sides or more
to one side according to its position. If not desired to change the distribution, the
distributor is fixed at the desired part of the spindle.
In order to prevent the wicks cf the stove being turned up too high, a stop is
arranged in the path of an arm adjustably fixed on the burner spindle and in a
duplex burner having the burners geared together one spindle may form a stop for
an arm adjustably secured to the other spindle or to the gear wheel on it.
In order to give an oil heating stove the appearance of an ordinary fire, the
metallic chimney is provided with an opening or openings covered by mica or
similar plates and small bars having holes in them are arranged across the chimney
opposite the opening. Tufts of asbestos are inserted in the holes and secured by
pincing up the holes or the asbestos may be secured between two bars clamped
together. The bars being small do not conduct much heat to the framework and
thus to the burners.
The heating stove is provided with an upper chamber connected to the chimney
by a metallic neck piece and so arranged that the gases pass up the centre and

In the accompanying two sheets of illustrative drawings
--
Fig. 1 is a vertical section of a petroleum stove provided with the lamp con-
structed according to this invention and Fig. 2 is a plan with part broken away to
show section on the line C-D of the same.
Figs. 3 and 4 are detail views of the wick raising and lowering mechanism.
Fig. 5 is a vertical section of a plate carrier gallery provided with hinged
extensions.
Fig. 6 is a section on the line E F of Fig. 5 showing only a corner of the upper
part of the stove.
Fig. 7 is a vertical section of a heater.
Fig. 8 is a sectional plan of the heater through the line A-B Fig. 7.
Fig. 9 is a vertical section of a chimney.
The body of the stove shown in Fig. 1 is composed of a plate carrier gallery B
combined or not with a metallic band A" and attached directly or by means of
this band to four metallic corner pieces A of any desired form themselves
attached to four flat or other suitably shaped iron standards A', and a base plate C
of sheet or cast iron.
The attachment of these different portions is effected by means of screws or
rivets. The corner pieces A have three surfaces giving great rigidity in fitting
together, the corner pieces being attached to the partition D by a screw on each
surface cut by the body.
The standards A' are provided with horizontal feet C₁ allowing of their rigid
attachment to the flat part of the base C by means of a single screw or rivet..
The partition D supporting the chimney F is attached to the body of the stove
or to the four corner pieces or to the four standards by means of screws or rivets
serving to increase the rigidity of the frame.
The plate carrier gallery of cast iron is connected to the metallic band A" or
to the corner pieces A or simply fits tightly over the metallic band A".
The corner pieces A and the standards A¹ shown on the drawing, Fig. 1 in two
parts connected together may be constructed in one piece extending from the plate
carrier gallery B to the base C.
The lamp E surmounted by its burner or burners E' slides on the base and can
be drawn out from the body of the stove.
In order to allow the simultaneous cooking of several aliments on a simple
heating plate, the plate carrier gallery B (Figs. 1 and 2) is provided with two
hinged extensions B' opening outwards or folding back and resting on the plate
carrier gallery as shown in Fig. 2. The upper rim of the gallery B and the edge
of the extension B₁ are each provided with a hole through which passes a pin G
allowing of the jointing of the extensions.
In Figs. 5 and 6 the extensions are composed simply, of a metallic wire B¹ the
two extremities of which can move backwards and forwards by sliding in the ear
pieces B bored with a hole of suitable size. The sliding extension B' shown
on the left of Fig. 5 is in the position of maximum distance from the gallery B
whilst the extension B' on the right side of Fig. 5 is shown resting on the
gallery B.
The extremity of the heat distributor H encircles the spindle H¹ Figs. 1, 2 and 6
and is hinged to this spindle. This distributor may slide or not from right to left
and rice versa along the spindle H'. It serves to distribute the heat under the
vessels submitted to the action of the flame in constant proportions if it is fixed in
the centre; and in varying proportions according to the position given it, if it is so
fitted as to slide along the spindle H'.
In order to avoid a smoky flame by the wick being accidentally raised too high a
clamping screw L screws into a bored collar M sliding on the regulating spindle-

page_text: When the clamping screw L is screwed up, the collar M and the screw L are
firmly connected and fixed on the regulating spindle with which these parts form
in some sort a portion and when the milled head is turned the tail of the clamping
screw L abuts against a stop N which arrests the rotating movement, thus
limiting the rotation and the height of the flame to the "maximum" point which
may be assigned to it.
Fig. 4 shows a variation of the same system of "maximum," acting by means of
a threaded nut L' screwing on the threaded end M¹ of the regulating spindle of
the second wick in a duplex burner (O and O' being two spur wheels permitting
the regulation of the two spindles from one milled head). The pressure of the nut
on the collar M firmly fixes it by screwing it against the spur wheel o and when
the projection L" which is fixed to the collar M" abuts on the regulating spindle
on which is fixed the milled head and which in this case acts as a stop, the whole
arrangement is arrested and the play thereby limited to the maximum point at
which the height of the flames will have been limited.
The same arrangements can be easily applied to gas taps to limit the degree of
opening of the taps to the suitable maximum point in order to avoid all production
of smoke at the upper part of the flame.
Fig. 7 shows a stove for heating rooms. To obtain a visible fire having the
appearance of a grate of solid combustible in an incandescent state, asbestos is
heated to redness above the flame in a chimney provided with openings covered
with mica so as to allow the inside of the stove to be scen. The fixing of the
tufts of asbestos is effected in an inexpensive manner and so as to avoid over-
heating the chimney which would result especially in oil burners in throwing on
the burners too great a quantity of radiated heat increasing the volume of the
flame and causing smoke.
Malleable cast iron bars P Figs. 7 and 9 are provided with holes at a suitable
distance apart in which are inserted tufts of asbestos R. On squeezing the bar
on each side of the hole the metal gives way, tightens round and clamps the tufts
of asbestos which are thus firmly fixed. These bars are only a few millimeters in
thickness and do not present any important mass of metal capable of radiating too
much heat on to the burners. They are represented as straight on the drawing.
but they might be curved and follow shapes corresponding to those of any kind of
burners. They may be single or double that is to say the asbestos may be clamped
in holes made in a single bar of any shape or be taken between two bars connected
together by rivets or in any suitable manner.
The chimney is provided with an extension F' designed to avoid any break in
the continuity between the chimney and the gas circulation chamber F to stop
all entry of cold air which wonld lower the temperature in the circulation
chamber F and would diminish the yield of radiant heat. The circulation takes
place as indicated by the arrows starting from the chimney. They rise in the
chamber F and descend in the duct T escaping then through the flue T'.
The outlet flue of the gases is provided with one or several openings y at its
lower part and with an opening of very small dimensions at its extremity; this
arrangement ensures the same draught in the stove when it burns in a room
unprovided with chimney and the gases consequently escape freely into the air as
when it burns in a fire place and its flue is partially inserted in the chimney of the
room. In the latter case the draught from the chimney is very powerful and
would exert a prejudicial influence on the heating of the room if the smallness of
the orifice did not reduce the outflow of the products of combustion and
consequently of the quantity of air brought to the chimney. A certain circulation
of air is established, the entrance being at y and the outlet at z. If a down draught
takes place in the chimney. it does not affect the combustion, the draught in the
stove not being interfered with since the gases coming down can momentarily
escape into the room through the opening y. When the stove burns in a room
without chimney the opening y serves, together with the hole z for the escape of
the gases.

page_text: 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. The construction of the body of petroleum gas or spirit stoves consisting of
four corner pieces connected at their upper parts to a cast iron gallery or to one
or more metallic bands; and connected at their lower ends to a base, supporting
the lamp or the burner substantially as described and shown in the drawings.
2. The construction of the body of petroleum gas or spirit stoves consisting of
four corner pieces connected at their upper part to a gallery or to a metal frame
and at their lower part to a diaphragm supporting the chimney in combination with
four supports in iron plate connecting the body to a base supporting the lamp or
burner substantially as described and shown in the drawings.
3. In a petroleum gas or spirit stove two sliding or hinged gallery extensions so
arranged at the upper part of the stove that they can be extended outwards or
rest upon the gallery itself without taking up room, substantially as described and
shown in the drawings.
4. In a petroleum gas or spirit stove a hinged heat distributor having a position
fixed at a particular point or capable of sliding along a spindle, and producing
the distribution of the heat in variable proportions substantially as described and
shown in the drawings.
5. In petroleum gas or spirit stoves a clamping screw designed to limit the
movement of rotation of the feed spindle or tap when the projecting pin abuts on
the stop substantially as described and shown in the drawings.
6. In petroleum gas or spirit stoves fixing tufts of asbestos in straight or curved
metal bars of small volume placed inside a chimney so as to avoid the radiation
of too great an amount of heat on to the burners substantially as described and
shown in the drawings.
7. In petroleum gas or spirit stoves an outlet flue characterised by the com-
bination with a small opening at the end of one or more holes in its under part for
the purpose of always maintaining the same draught in the stove substantially as
described and shown in the drawings.
