We, JOHN JULIUS SCHULZ CURTIUS of N° 174 New Bond Street Agent and
HENRY DAVIS POOLE of No 33 Chancery Lane Solicitor both in the County of
Middlesex do hereby declare the nature of our invention for "AN IMPROVED STOVE
OR LAMP FOR BURNING PETROLEUM a communication to us from abroad by
Nikolaus de Snessoreff of St Petersburg a General in the Russian Army to be as
follows:-
This Invention has for its object an Improved table or other stove or lamp for
burning petroleum.
This Stove or lamp as I prefer to construct it consists of a cylindrical oil vessel
which is made to open like a Box, and on the top of the oil vessel there is supported
the wick tube and apparatus for adjusting the height of the wick.
I employ a flat wick say about two millimetres thick but the thinner the better
but the dimensions may be varied. The wick is carried upwards in its wick tube
through the top of the oil vessel and through a table which is supported by a
pedestal upon the cover of the oil vessel. Over the table there is a semi circular
dome enclosing a chamber within which the wick tube terminates. Air to support
combustion enters this chamber by two longitudinal openings one on either side
passing through the table and parallel to the wick. Within this chamber and at a
distance of five millimetres above the top of the wick there is a plate with a longi-
tudinal slit in it corresponding in length with the wick the flame in rising passes
through this slit There is also a corresponding slit in the top of the outer dome
which also is at a distance of five millimetres from the slotted plate within the
Chamber.
These arrangements ensure a very complete combustion of the petroleum.
The air entering the chamber by the apertures in the table mingles first with the
petroleum vapour as it rises from the wick and together they pass through the slit
n the inner plate above the wick Then as the flame rises above this inner plate

upon the flame and with it they issue through the slit in the top of the dome The
result is production of a flame which has great heating power it is blue in the lower
part with a luminous crown.
No chimney is required for this stove or lamp and it produces no smoke.
As already stated the dimensions may be varied but I always maintain substan-
tially the same proportion between the thickness of the wick the distance from the
top of the wick to the inner slotted plate and the distance of the latter from the
slit in the top of the dome.

DAVIS POOLE of No 33 Chancery Lane Solicitor both in the County of Middlesex
do hereby declare the nature of our invention for "AN IMPROVED STOVE OR LAMP
FOR BURNING PETROLEUM" (a communication to us from abroad by Nikolaus
de Snessoreff of St Petersburg a General in the Russian Army) and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention has for its object an improved table or other stove or lamp for
burning petroleum.
This stove or lamp as we prefer to construct it consists of a cylindrical oil vessel
which is made to open like a box, and on the top of the oil vessel there is supported
the wick tube and apparatus for adjusting the height of the wick.
We employ a flat wick say about two millimetres thick but the dimensions may
be varied. The wick is carried upwards in in its wick tube through the top of the
oil vessel and through a table which is supported by a pedestal upon the cover of the
oil vessel. Over the table there is a semi-circular dome enclosing a chamber within
which the wick tube terminates. Air to support combustion enters this chamber
by two longitudinal openings one on either side passing through the table and
parallel to the wick. Within this chamber and at a distance of five millimetres or
approximately above the top of the wick there is a plate with a longitudinal slit in
it corresponding in length with the wick; the flame in rising passes through the
slit. There is also a corresponding slit in the top of the outer dome which also is
at a distance of five millimetres or approximately from the slotted plate within the
chamber.
These arrangements insure a very complete combustion of the petroleum.
The air entering the chamber by the apertures in the table mingles first with the
petroleum vapour as it rises from the wick and together they pass through the slit
in the inner plate above the wick. Then as the flame rises above this inner plate
it meets Interal currents of air rising within the dome on either side; these impinge
upon the flame and with it they issue through the slit in the top of the dome.
The
result is production of a flame which has great heating power; it is blue in the
lower part with a luminous crown.
No chimney is required for this stove or lamp and it produces no smoke.
As already stated the dimensions may be varied but we always maintain sub-
stantially the same proportion between the thickness of the wick, the distance from
the top of the wick to the inner slotted plate and the distance of this latter from
the slit in the top of the dome.
The arrangement may in some cases be simplified by the omission of the dome,
replacing it simply by a flat plate in which is the slit or aperture for the passage
of the flame.
Or both plates may be carried by a casing to which air is admitted at the lower
part and perforations in the lower plate permit it also to enter and pass to the
Hame between the plates.

page_text: case N carries at a distance of 5 or 6 milimetres above the top of the wick tube,
the plate K in which is a slit K¹, the plate K is also perforated at O. O. to allow
air to enter from the lower part of the case N between the lower plate K and the
upper plate J. The plate J has a slit in it at J¹
The plate J is here shown somewhat domed in the part where the slit J' is
formed, this is for the purpose of giving a rounded form to the flame. The centro
of this dome is at a distance of 5 or 6 milimetres from the plate K.
Also to give
a rounded form to the flame, the slit K¹ is somewhat longer than the wick is broad
and the slit J is longer than the slit K'.
This wick may be used with a glass chimney of cylindrical form. These lamps
are capable of burning the oil known as "Solar" and pyronaphtha and all the usual
varieties of Petroleum oil.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, We declare that what
we claim is
(1.) A stove or lamp with a wick tube terminating within a chamber having a
slit at the top for the flame to issue and apertures at the lower part for the admis-
sion of air and with a plate or shield within the chamber and above the wick tube
also having a slit for the passage of the flame substantially as described.
(2.) The combination of the wick tube E the slit K'in a plate K over and
parallel to the wick tube and a slit J¹ in a second plate J immediately over the
first plate, the whole being arranged substantially as described and so that air
ineets the flame below the lower plate and also in the interval between the plates
substantially as described.
(3.) Our improved stove or lamp with the parts in connection with the burner
arranged and proportioned substantially as described and represented in the
annexed drawings with the slits J' and K' of a width approximately equal to the
distance between them and with the burner tube terminating at a like distance
below the lower slit K
