Improvements in Lamps suitable for Soldering Purposes.
We, GUSTAV BARTHEL in Niederpoyritz near Dresden, Chemist, and AUGUST
SCHONE, in Dresden, Kingdom of Saxony, German Empire, 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 reference to a lamp suitable for soldering purposes and
adapted for use without a wick and without a second flame, and in which a burning
or burner tube traversing the vessel that contains the liquid fuel, is dispensed
with.
Such a lamp is illustrated in the annexed drawings.
a is the vessel for liquid fuel; this vessel may be of any convenient shape; it is
provided with a handle and with an opening for filling the vessel, closed by a
screw plug c furnished with a safety valve.
Below the vessel a is arranged the burner tube d into which projects the small
pipe e which extends into the upper part of the vessel a, and within the tube
terminates with a fine aperture.
The burner tubed is provided at one end with a device for the admission of air
in regulated quantity.
The vessel is mounted on a stand g of convenient shape, so that the lamp may
stand.
e.
In using the lamp, the vessel a is partly filled with a liquid fuel, such for
example as alcohol (methylated spirit) the level of such liquid being kept below
the upper aperture of the pipe The vessel is then heated by any convenient
flame, until vapor developed issues from the pipe e within the burner tube d and
after being ignited burns with an intense flame, this flame will cause the continued
development of vapors until all the liquid fuel in the vessel a has been consumed.
The intensity of the flame may be regulated by the admission of air at by
turning the disc so as to cause its aperture to correspond more or less with those in
the end of the tube d.
The lamp according to this construction may be conveniently held in any desired
position, so that the Hame issues in an upward or a downward direction, thus
facilitating the soldering process at places to which it would otherwise be difficult
to direct the flame.
We do not limit ourselves to the exact form of the lamp as illustrated.

SPECIFICATION.
Improvements in Lamps suitable for Soldering Purposes.
We, GUSTAV BARTHEL formerly of Niederpoyritz near Dresden but now of
Blasewitzerstrasse 37° Dresden, Chemist, and AUGUST SCHÖNE, Dresden,
Kingdom of Saxony, German Empire, 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 reference to a lamp suitable for soldering purposes and
adapted for use without a wick and without a second flame and in which a burning

Such a lamp is illustrated in the drawings left with our Provisional Specification.
a is the vessel for liquid fuel. This vessel which may be of any convenient
shape, is provided with a handle band with an opening for filling the vessel closed
by a screw plug c furnished with a safety valve. Below the vessel a is arranged
the burner tube d into which projects the small pipe e which extends into the upper
part of the vessel a and within the tube terminates with a fine aperture. The
burner tube d is provided at one end with a device for the admission of air in
regulated quantity.
The vessel a is mounted on a stand of convenient shape, so that the lamp may
⚫stand.
In using the lamp, the vessel a is partly filled with a liquid fuel, such for
example as alcohol (methylated spirit) the level of such liquid being kept below
the upper aperture of the pipe e. The vessel is then heated by any convenient
flame, until vapour thereby developed issues from the pipe e into the burner tube d;
and after being ignited burns with an intense flame; this flame will by conduction
of heat through the tube d to the vessel a cause the continued development of
vapour until all the liquid fuel in the vessel a has been consumed. Thus the
necessity of using a second flame for this purpose as heretofore usual is obviated.
The intensity of the flame may be regulated by the admission of air at by
turning the disc so as to cause its apertures to correspond more or less with those
in the end of the tube d.
The lamp according to this construction may be conveniently held in any desired
position, so that the flame issues in an upward or a downward or horizontal
direction, thus facilitating the soldering process at places to which it would other-
wise be difficult to direct the flame.
We do not limit ourselves to the exact form of the lamp as illustrated.
Lamps according to this invention and of suitable sizes may be used for various
purposes such for example as paint removing and melting metals.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that
what we claim is :-
A lamp suitable for soldering purposes, constructed for use without a wick, and
comprising the vessel a for containing the liquid fuel and a burner tube d arranged
below and in contact with the said vessel and into which combustible vapour
generated in the said vessel by heat, passes through a tube such as e and is burnt
by air that enters through one end of the burner tube and the supply of which can
be regulated as set forth, the arrangement being such that an intense heat can be
obtained part of which is utilized to cause continued evaporation of liquid fuel in
the said vessel a substantially as hereinbefore described.
