I, MORITZ HORWITZ, of 106, Lützowstrasse, Berlin in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a transportable incandescent vapour lamp for
liquid combustible.
By my invention the lamp is so constructed that the liquid is prevented over-
flowing out of the vaporiser into the burner and the burner is so formed that the
incandescent body is always evenly heated, and thus is always brought into an even
state of incandescence.
The actual vaporiser contains a perforated pipe round which a wick is coiled and
which is also partially filled by another wick. The vaporiser is also provided at
some distance below its cover with a plate which limits the outer wick at the top,
but however leaves free the opening of the perforated tube. In this manner.there
is formed above the wick a special or separate chamber from which the vapour is
drawn to the burner through an opening arranged at the side and a passage or
nozzle communicating with said opening, which opening may be closed or opened
by means of a valve in the ordinary manner.
An insertion piece is arranged in the buruer tube to conduct the heat of the
illuminating or lighting flame to the greatly extended walls of the burner and thus
to the vaporiser.
In the form of construction of vaporiser described, particles of liquid are
prevented from coming into the vapour passage and from there into the burner.
The moment in fact that particles of liquid are carried along with the current of
vapour produced in the perforated pipe, they encounter the cover of the vaporiser
and fall back into the pipe even if they are not vaporised by contact with the said
cover.
In consequence of the vapor orifice being arranged at one side, the said particles
of liquid can under no circumstances reach the burner.
As moreover in spite of the most careful attention in the boring of the nozzle
passage, the current of vaporised combustible frequently enters the actual burner
in a somewhat oblique direction, and so only brings one side of the incandescent
body into incandescence, or in other words only beats the same partially and not
uniformly, the insertion piece or support for the incandescent-mantle carrier
(differing from the form of construction hitherto employed) consists of a lower
cylindrical part exactly fitting the burner, on which an upper cylindrical part of
less diameter is formed. The lower larger cylindrical part is formed with a number
of vertical passages, which preferably widen out downwards. In place of these
passages, side recesses or vertical grooves may be employed which also may widen
out downwards.
The upper cylindrical part of reduced diameter is provided with a number of
horizontal perforations. If then the current of vapour entering the burner tube
through the nozzle assume an oblique direction, for instance is directed to the left,
the major part of the mixture of air and vapour will escape upwards through the
vertical passages situated on the left side, and thus more or less impede the escape
of the mixture of air and vapour from the horizontal perforations situated on the
same side. The natural consequence of this is that the remaining current of gas

page_text: will be conveyed to the horizontal perforations situated on the other side, and thus
the upward rising of the mixture through the vertical passages situated on this side
will be more or less impeded.
The result of this is that by the arrangement hereinbefore described of the
support for the incandescent-mantle carrier, an equalization of the vapour and air
current is effected, so that said current flows evenly to the burner strainer and thus
produces incandescence of the mantle in an even manner.
The arrangement of the horizontal perforations and vertical passages affords also
a further advantage that the currents of vapour encounter one another on the
principle of a counter current, so that a whirling motion is produced; which has for
its consequence a thorough admixture of the vapour with the air.

I, MORITZ HORWITZ of 106 Lützowstrasse, Berlin in the Empire of Germany,
Manufacturer, 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 a transportable incandescent vapour lamp for
liquid combustible.
"By my invention the lamp is so constructed that the liquid is prevented over-
flowing out of the vaporiser into the burner and the burner is so formed that the
incandescent body is always evenly heated and thus is always brought into an even
state of incandescence.
In the accompanying drawings,
Figure 1 is a vertical section of the vapouriser and burner, and
Figure 2 is a plan view of the burner support.
The actual vapouriser a contains a perforated pipe b round which a wick is
coiled and which is also partially filled by another wick d. The vapouriser a is
also provided at some distance below its cover e with a plate f which limits the
outer wick c at the top but however leaves free the opening of the perforated tube.
In this manner there is formed above the wick a special or separate chamber g from
which the vapour is drawn to the burner & through an opening h arranged at the
side and a passage or nozzle communicating with said opening, which opening may
be closed or opened by means of a valve i in the ordinary manner.
An insertion piece m is arranged in the burner tube k to conduct the heat of the
illuminating or lighting flame to the greatly extended walls of the burner and thus
to the vapouriser.
In the form of construction of vapouriser described, particles of liquid are
prevented from coming into the vapour passage and from there into the burner.
The moment in fact that particles of liquid are carried along with the current
of vapour produced in the perforated pipe 6 they encounter the cover e of the
vapouriser and fall back into the pipe b even if they are not vapourised by contact
with the said cover.
In consequence of the vapour orifice h being arranged at one side, the said
particles of liquid can under no circumstances reach the burner.
As moreover in spite of the most careful attention in the boring of the nozzle
passage, the current of vapourised combustible frequently enters the actual burner

page_text: in a somewhat oblique direction, and so culy brings one side of the incandescent
body into incandescence, or in other words only heats the same partiaily and not
uniformly, the insertion piece or support m for the incandescent-nantle carrier n
(differing from the form of construction hitherto employed) consists of a lower
cylindrical part exactly fitting the burner on which an upper cylindrical part of
less diameter is formed. The lower larger cylindrical part is formed with a number
of vertical passages o, which preferably widen out downwards. In place of these
passages o, side recesses or vertical grooves, Figure 2, may be employed which
also may widen out downwards.
The upper cylindrical part of reduced diameter is provided with a number of
horizontal perforations p. If then the current of vapour eutering the burner tube
through the nozzle assume an oblique direction, for instance is directed to the left,..
the major part of the mixture of air and vapour will escape upwards through the
vertical passages o situated on the left side and thus more or less impede the escape
of the mixture of air and vapour from the horizontal perforations p situated on the
same side. The natural consequence of this is that the remaining current of gas.
will be conveyed to the horizontal perforatious p situated on the other side, and
thus the upward rising of the mixture through the vertical passages o situated on
this side will be more or less impeded.
The result of this is that by the arrangement hereinbefore described of the
support m for the incandescent-mantle carrier n, an equalisation of the vapour and
air current is effected so that said current flows evenly to the burner strainer and
thus produces incandescence of the mantle in an even manner.
The arrangement of the horizontal perforations p and vertical passages o affords
also a further advantage that the currents of vapour encounter one another on the
principle of a counter current, so that a whirling motion is produced, which has for-
its consequence a thorough admixture of the vapour with the air.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to he performed, I declare that what I
claim is :-
1. A transportable incandescent vapour lamp for liquid combustible, characterised.
by the vapouriser having above the wick a special chamber with arrangement for..
carrying off the vapour at the sides, the cover of which chamber throws back all.
liquid carried along with the vapour current, substantially as hereinbefore set
forth.
2. In an incandescent vapour lamp such as described, a carrier (m) for the mantle
support (n) arranged in the burner (*) over the air inlets, consisting of two
cylindrical parts lying one over the other, the lower wider one of which has vertical
passages (o) and the upper narrower one horizontal perforations (p) with the object
of equalising the upward movement of the mixture of vapour and air, and of causing
a whirling motion of the current of mixed vapour and air emerging at an angle for
the purpose of producing a thorough mingling of the vapour and air substantially-
as hereinbefore set forth.
