PROVISIONAL SPECIFICATION.
An Improved Vapouriser for Liquid Combustibles for Incandescent
Lighting or Heating Purposes.
I, FELIX VICTOR COSMUS BROкк of 35 Luisen-Ufer, Berlin in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object an improved vapouriser for liquid combustibles
for incandescent lighting or heating purposes.
An annular retort, formed of caps and provided externally with a non-con-
ducting casing is provided with one, two or more passages which admit air to
the inner heating space of the retort and serve for igniting an ordinary heating
Hame. Outside the non-conducting covering a ring, revoluble by means of a
handle, is mounted, the lower edge of which ring is provided with a recess which
engages over a wick-operating spindle and forms with the latter a projecting
device for turning; four openings facing one another, are arranged at the level
of the air passages of the retort, two of the openings being each covered with a
cap opening below, so that the air entering the heating chamber of the retort,
must assume a course from below upwards into the cap and then through the
air passages of the retort. The heating chamber of the retort is enclosed or shut
off beneath the air passages by means of a bottom plate which carries in the
ordinary manner a tube which contains a heating wick. The bottom plate may
eventually be also provided, in addition to the wick tube, with one or more
suitable openings or nozzles, in order to allow of the vapour or the like rising
from the vessel containing the combustible to be burnt above the plate and used
for heating the retort.
Above the heating flame a central pipe is arranged, which pipe is secured in the
cover of the inner retort walls and itself passes through the neck of the retort
which is open above and covered with a nozzle cap, and also through the nozzle
itself and through the Bunsen burner pipes and burner cap situated on the nozzle
in such a way that the said pipe still projects beyond the incandescent body, such
for instance as a mantle (which may eventually be suspended on the pipe) arranged
over the burner cap. The removable pipe carrying the burner cap is provided
in the ordinary way with a perforated piece or sieve and a gallery, which latter
carries an ordinary glass cylinder. The said pipe may eventually be made to
divide into several parts, that is to say, may be so arranged that the upper part
is mounted on the burner cap in such a way that the removable pipe of the burner,
the burner-cap, the divided tube, the glass cylinder, the incandescent body or
the like, may be removed or lifted off from the burner pipe or from the lower
part of the pipe. A suction or capillary wick firmly fitted into the lower part
of the retort is somewhat more loosely fitted in the upper part of the retort, for
instance, above the air passages and may be held away from the inner heated walls
of the retort in the ordinary manner by means of a numerously perforated casing
or a wire sieve so that the free evaporating surface of the wick is increased.

page_text: The apparatus may be separated from the reservoir by means of an insertion of
non-conducting material and be covered below with a perforated casing.
The working of the burner is as follows-
First, by means of the handle, the ring is first turned into the position in which
its two openings coincide with the air passages of the retort and then the heating
wick is ignited, after which the ring is turned further until its other pair of
openings which are capped coincide with said air passages. The vapour of the
combustible then evolved rises upwards and passes out of the nozzle into the
Bunsen burner pipe and finally mixed with air is ignited above the burner cap.
By the resulting upper heating flame the upper end of the central pipe becomes
very hot, whereby a very energetic current of air is produced from the lower
end (which remains cooler) of the air passage formed by, this pipe, the retort
heating chamber, the air passages of the retort and also the caps, which current
of air mixed with the waste gases of the heating flame is conveyed. out of the
incandescent body and blown into the glass cylinder and again causes in this
latter a vigorous draught of air through the sieve or the like, of the gallery. As
however the central pipe is strongly heated from top to bottom, and the burner
pipe in consequence of the burner cap becoming hot is also kept very warm, the
combustible vapour flowing from the nozzle passes through a passage heated on
both sides and can neither cool down nor condense on its course to the burner cap.
If the lamp is to be extinguished, the ring is again brought into its initial
position so that the air passages are closed, the heating flame of the wick is
extinguished, and the development of vapour and the energetic draught of air
from the central tube into the interior of the glass cylinder ceases.
The extinguishing of the flame of the heating wick may however be effected
in another manner. For instance, a second tube may be arranged around the
wick tube in such a way that it may be pushed up above the latter. This second
tube is provided with teeth or the like to be engaged by a pinion whereby the tube
may he raised. The upper edge of the tube then stands far above the edge of the
wick tube and above the wick and cuts off the air supply, so that the wick flame
is extinguished.

An Improved Vapouriser for Liquid Combustibles for Incandescent
Lighting or Heating Purposes.
I, FELIX VICTOR COSMUS BROKK of 35, Luisen-Ufer, Berlin in the Empire of
Germany 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 has for its object an improved vapouriser for liquid combustibles
for incandescent lighting or heating purposes. :
It is shown in the accompanying drawings
Figure 1 being a longitudinal section of the vapouriser; Figures 2, 3 and 4
plan views and Figure 5 a side view of a wind shield and extinguisher; Figure 7
is a modification of the pipe for carrying off the waste gases which pipe may be
made to take apart and may be partly arranged on the burner cap. Figure 6

page_text: is a modification of the retort and Figure 8 a modified' form of construction of
the device for extinguishing the heating flame wick.
An annular retort, formed of caps a and b and provided externally with a
non-conducting casing is provided with one, two or more passages e which admit
air to the inner heating space of the retort and serve for igniting an ordinary
heating flame. Outside the non-conducting covering i, a ring t, Figures 1 and 5,
revoluble by means of a handle is mounted, the lower edge of which ring is pro-
vided with a recess t¹ which engages over a wick-operating spindle h and forms
with the latter a projecting device for turning; four openings y and z,
Figures 2-5 facing one another are arranged at the level of the air passages e
of the retort, two of the openings z being each covered with a cap k opening below,
so that the air entering the heating chamber of the retort, Figure 1, must assume
the course indicated by the arrows from below upwards into the cap k and then
through the air passages e of the retort. The heating chamber of the retort is
enclosed or shut off beneath the air passages e by means of a bottom plate f which
carries in the ordinary manner a tube g which contains a heating wick q. The
bottom plate f may eventually be also provided, in addition to the wick tube g,
with, one or more suitable openings or nozzles, in order to allow of the vapour
or the like rising from the vessel a containing the combustible to be burnt above
the late f and used for heating the retort.
Above the heating flame a central pipe 'c is arranged, which pipe is secured in
the cover of the inner retort walls and itself passes through the neck a¹ of the
retort which is open above and covered with a nozzle cap m, and also through
the nozzle itself and through the Bunsen burner pipes ns and burner cap r.situated
on the nozzle in such a way that the said pipe still projects beyond the incan-
descent body, such for instance as a mantle , Figure 1, (which may eventually

be suspended on the pipe c) arranged over the burner cap r.
pipes carrying the burner cap r is provided in the ordinary way with a perforated
piece or sieve s and a gallery 2, which latter carries an ordinary glass cylinder a².
The said pipe c may eventually be made to divide into several parts, see Figure 7,
that is to say, may be so arranged that the upper part c¹ is mounted on the burner-
cap, r in such a way that the removable pipe s, Figure 1, of the burner, the burner
cap r, the divided tube c', Figure 7, the glass cylinder a, the incandescent
body or the like, may be removed or lifted off from the burner pipe n, Figure 1,
or from the lower part of the pipe c, Figure 7. A suction or capillary wick p
firmly fitted into the lower part a b, Figure 1, of the retort is somewhat more
loosely fitted in the upper part of the retort, for instance, above the air passages e
and may be held away from the inner heated walls of the retort in the ordinary
manner by means of a numerously perforated casing or a wire sieve o so that the
free evaporating surface of the wick is increased. The apparatus may be
separated from the reservoir by means of an insertion of non-conducting material
and be covered below with a perforated casing j.
The working of the burner is as follows:-
in

By means of the handle h¹, the ring t is first turned from the position shown
in Figure 4 into that shown in Figure 3 in which its two openings y coincide
with the air passages e of the retort and then the heating wick q is ignited, after
which the ring is turned further from the position shown in Figure 3
until

upper heating flame the upper end of the central pipe c becomes very hot, whereby
a very energetic current of air is produced from the lower end (which remains
cooler) of the air passage formed by this pipe, the retort heating chamber, the air
passages of the retort and also the caps, which current of air mixed with the

page_text: waste gases of the heating flame is conveyed out of the incandescent body and
blown into the glass cylinder and again causes in this latter a vigorous draught
of air through the sieve or the like of the gallery. As however the central pipe c
is strongly heated from top to bottom, and the burner pipe s n in consequence of
the burner cap r becoming hot is also kept very warm, the combustible vapour
flowing from the nozzle passes through a passage heated on both sides and can
neither cool down nor condense on its course to the burner cap r.
If the lamp is to be extinguished, the ring t is again brought from the position
shown in Figures 1 and 2 into that shown in Figure 4, i.c. into its initial position
so that the air passages e are closed, the heating flame of the wick 7 is extinguished,
and the development of vapour and the energetic draught of air from the central
tube c into the interior of the glass cylinder ceases.
The extinguishing of the flame of the heating wick may however be effected
in another manner, as shown in Figure 8. For instance, a second tube n³ may
be arranged around the wick tube g in such a way that it may be pushed up
above the latter. This second tube 3, Figure 8, is provided with teeth or the
like to be engaged by an ordinary pinion on the spindle h, whereby the tube may
be raised and brought into the position shown in dotted lines at nt, Figure 8
and the said spindle does not in this case as in Figure 1 engage in the wick q.
The upper edge of the tube 3 then stands far above the edge of the wick tube g
and above the wick and cuts off the air supply, so that the wick flame is
extinguished.
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 vapouriser for liquid combustibles for incandescent lighting or heating pur-
poses, characterized by the arrangement of an annular retort or cap (a a 6 m)
with one or more passages (e) adapted to be opened or closed by means of a
revoluble ring (t) which passages may be so covered that the inflowing current
of air is protected against too strong a pressure, and by the heating wick (q) being
raised and lowered either directly by means of a spindle () and pinion engaging
with it, or by the wick tube (g) being surmounted by a second tube (n) provided
with a rack or the like, which latter tube may be raised or lowered by means of
a spindle (h) and pinion in order to allow of the heating flame being lighted or
extinguished, and further by a pipe (c), which if desired may be made to be
taken apart being arranged on the said retort with the object of conveying heat
to the retort and preventing condensation of the combustible vapour rising around
the retort as well as for producing an artificial energetic draught of air to carry
off the hot gases, substantially as hereinbefore described.
