Improvements in Incandescent Light Burners for Liquid
Hydro-carbon.
I, HUGO POLLAK, of 34, Wallgasse, Vienna, VI., Austria, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved incandescent light burner constructed
preferably for the consumption of hydrocarbon liquids.
The improvements consists of a horse-shoe like wick tube, which is filled with a
wick reaching from the top or orifice of the said tube to the bottom of a basin.
Upon the said orifice is mounted a tube the upper end of which is closed and which
forms a cap. Inside this cap is another tube which near the orifice of the said
wick tube passes through the wall and leads to a chamber at the side of the said
wick tube. This chamber has a vertical outlet and a horizontal branch pipe in
which is rendered adjustable a spindle packed at its outer end and having a knob
whilst its inner end is formed with a valve whereby the orifice of the pipe leading
from the interior to the said chamber can be more or less closech
Over the wick tube a tube is arranged which rests upon the said branch pipe and
which all round is formed with air openings. Upon the lower end of this tube a
bonnet is placed and upon the latter rests a tube carrying an incandescent mantle.
Between the upper end of the last named tube and that of the tube over the wick
tube wire gauze is inserted and the said mantle suspended over the upper end of its
tube in the usual way.
The burner works as follows:-
After having filled the aforesaid basin with a suitable hydro-carbon liquid
poured through a hole in the same furnished with a plug and a piece of wool or
the like saturated with spirit has been held below the aforesaid chamber for about
30 seconds, the hydro-carbon liquid in the wick tube begins to gasify.
The gases then rise into the said cap and are conducted by the aforesaid thin
tube downwards into the said chamber and will issue from the outlet of the latter.
After removing the light the hot limbs of the wick tube continue the gasification
and the gas issuing from the said outlet will mix with the air which enters through
the openings in the tube next around the wick tube and leave through the aforesaid
wire gauze where it will ignite and cause the incandescent mantle to glow in the
usual way.
The heat issuing heats the said cap in such a manner that owing to its con-
ductivity will continue to heat the limbs of the wick tube and thus render the
gasification continuous.
In order to prevent the basin becoming hot and thus obviate explosions, the
limbs of the wick tube are soldered into a separate tube which isolates the heated
parts thereof from the burning liquid.

at the outlet of the aforesaid chamber.
Improvements in Incandescent Light Burners for Liquid
Hydro-carbon.
I, HUGO POLLAK, of 34, Wallgasse, Vienna, VI.,, Austria, 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 relates to an improved incandescent light burner constructed
preferably for the consumption of hydrocarbon liquids.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference in-
dicating like parts in the various figures.
Figs. 1 & 2 are both longitudinal sections at a right angle to each other, Fig. 3
a sectional plan of Fig. 1 at line rr, Fig. 4 a sectional plan of Fig. 2 at line y-y,
Fig. 5 a plan of the top of the burner, Figs. 6, 7, 8 & 9 details of my improved
burner.
In carrying out my invention and referring more particularly to Figs. 1, 2, 3 & 5,
the improvements consist in providing a horse-shoe like wick tube a, which is filled
with a wick b reaching from the top or orifice of the said tube to the bottom of the
basin A. Upon the orifice is mounted a tube d the upper end of which is closed
and which forms a cap. Inside this cap is another tube e which near the orifice
of the said wick tube passes through the wall and leads to a chamber f at the side
of the wick tube a. This chamber has a vertical outlet g and a horizontal branch
pipe furnished internally with a thread i in which is rendered adjustable a
spindle k packed at its outer end and having a knob whilst its inner end is
formed with a valve m whereby the orifice of the pipe leading from the interior
to the suid chamber can be more or less closed.
f
Next over the wick tube a, is arranged the tube which having a slot o, rests
upon the said branch pipe and which is formed all round with air inlets
the lower end of this tube a bonnet 9 is placed and upon the latter rests a tube r
p. Upon
carrying an incandescent mantle.
Between the upper end of the tuber and that of the tube n over the wick tube
wire gauze s is inserted and the mantle t suspended over the upper end of the tuber
in the usual, way.
The burner works as follows:-
After having filled the basin A with a suitable hydrocarbon liquid, poured in,
through a hole formed in the basin and furnished with a plug u and a piece of
wool v, see Fig. 9, or the like saturated with spirit has been held below the chamber
f for about 30 seconds, the hydro-carbon liquid in the wick tube a begins to gasify.
The gases then rise into the cap d and are conducted by the thin tube e down-
wards into the chamber f from which they issue through the outlet g. After remov-
ing the light, the hot limbs of the wick tube a continue the gasification and the gas
issuing from the gaid outlet, will mix with the air which enters through the open-
ings in the tube n next around the wick tube a and leave through the wire

page_text: gauze where it will ignite and cause the incandescent mantle to glow in the
usual way.
The heat issuing, heats the cap d and the latter being conductive will continuously
heat the limbs of the wick tube and thus render the gasification continuous.
In order to prevent the basin A becoming hot and thus obviate explosions, the
limbs of the wick tube a are soldered into a separate tube w which isolates the
heated parts thereof from the burning liquid.
The wire gauze s prevents also the flame from beating back and thus ignition
at, the outlet g of the chamber f.
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:-
d
1st. An incandescent light burner for liquid hydro-carbon, consisting of a
horse-shoe like wick tube a terminating at its upper end in a cap which surrounds
the upper end of a pipe e adapted to conduct the gases into the chamber f, from
whence they issue and mix at g with air entering through openings and after
passing through wire gauze s will cause the incandescent mantle t to glow, the said
incandescent mantle being so arranged that the heat radiation will continuously
heat the cap d, all substantially as set forth.
2nd. In an incandescent burner such as specified in the preceding claim, the
device i, k, l, m adapted to cut off the gas supply pipe e and the tube w in the
basin A which prevents the liquid in the latter coming into direct contact with the
hot wick tube a, all substantially as set forth.
Dated this Zoth day of November 1898.
