I, LUDWIG OLIVEN, of 14 Anhalt Strasse, Berlin, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in soldering-stoves and is more especially
applicable to stoves employed in the soldering of aluminium.
According to my invention the stove, which may be in the form of a rectangular
metal casing lined at those parts subjected to the action of fire with any suitable
refractory material, is provided with a flat top and with a hollow conical chamber
projecting from one of its sides, the flat top being destined for use when soldering
flat articles, such as plates, and the hollow conical chamber for use when soldering
round or curved articles, such as tubes. Both of these parts are advantageously
made of some substance that is a good conductor of heat, such as copper, in order
to obtain a more even distribution of heat thereon.
Two outlets are provided for the escape of the heated gases and products
of combustion from the stove, one of them leading to the chimney and the other to
the before mentioned conical chamber. By means of a suitable conduit controlled
by dampers or valves the course taken by the heated gases and products of
combustion may be conducted either to the conical chamber when this is required
to be used and thence through the said conduit to the chimney, or when the flat top
plate is required to be used may be allowed to pass direct to the chimney without
being deflected through the conical chamber and conduit.
The conical chamber is in some cases provided with an internal conical tube,
which may be perforated, said tube being so arranged as to leave an annular space
between itself and the interior of the surrounding conical chamber and serving to
distribute the heated gases more evenly onto the latter. In order to permit
of ready access to the interior of the conical chamber for cleaning purposes,
furnish its free end with a removable cap.

I, LUDWIG OLIVEN, of 14 Anhalt Strasse, 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 relates to improvements in soldering stoves and is more especially
applicable to stoves employed in the soldering of aluminium.
According to my invention the stove consists of a rectangular or other suitably
shaped chamber having a flat top, and having projecting from one of its sides
[Price 8d.1

page_text: a conical tube, or conically shaped chamber similar in shape to the beak of an anvil.
Two outlets are provided for the escape of the heated gases and products of
combustion from the stove, one of the said outlets leading to the chimney and the
other to the before mentioned conically shaped chamber. By means of a conduit
or passage controlled by suitably arranged dampers the heated gases and products
of combustion can be conducted either to the conically shaped chamber and
thence through the aforesaid conduit to the chimney, or can be allowed to pass
directly to the chimney without being deflected through the conically shaped
chamber.
In order that my said invention may be clearly understood and readily carried
into effect 1 will proceed to describe the same more fully with reference to the
accompanying drawings, in which
Figure 1. is a side elevation of a stove constructed according to my invention.
Figure 2 is a vertical section of the same, and
Figure 3 is a section ou the line 1, 1 of Figure 2.
A is the body of the stove; B the flat top; C the conically shaped chamber;
D the passage leading from the said chamber to the chimney; and D' D² dampers
for controlling the course of the heated gases and products of combustion from
the stove.
The body of the stove consists of an outer metal casing lined with fire bricks or
other refractory material a having openings a¹ a² therein, the former of which leads
to the chamber C and the latter to the chimney. The aforesaid opening a¹
is provided with a conically shaped metal tube c having perforations near its
outer end, the said tube e being so arranged as to leave an intermediate space c
between itself and the interior of the surrounding conical chamber C. By arranging
the inner tube c in this manner a better distribution of the heated gases is effected
as they enter the conical chamber C, and consequently the said chamber becomes
more evenly heated. is a removable cap or cover with which the outer end of
the chamber c is furnished. By removing this cap or cover ready access can be
had to the interior of the said chamber for cleaning purposes.
The flat top B of the stove is preferably composed of a stout copper plate upon
which the soldering of flat articles such as tablets or plates is effected. The
chamber C is likewise preferably composed of copper and is intended for use when
soldering circular or curved articles such as tubes."
When it is desired to solder only flat articles the dampers D1 and D2 are set into
the position indicated in Figure 3, the heated gases and products of combustion
then passing through the opening a direct to the chimney without materially
heating the chamber C. When it is desired to solder curved articles the before
mentioned dampers are reversed, that is to say the damper D2 is pushed in and the
damper D' drawn out; the heated gases and products of combustion then pass
through the opening a¹ and enter the chamber C flowing away along the space c² to
the conduit D whence they pass to the chimney.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A soldering stove having a metallic top and a lateral metallic chamber into
which the heated gases and products of combustion from the stove can be
directed at the will of the operator substantially as described and for the purpose
specified.
2. A soldering stove consisting of a body having a flat metallic top and w
conically shaped lateral metallic chamber communicating with the chimney by
means of a conduit or passage controlled by dampers substantially as described and
for the purpose specified.
3. In a soldering stove such as. that herein above, specified, the heat distributing
tube e located within the chamber C substantially as described and for the purpose
specified..

page_text: 4. The improved soldering stove having its parts constructed and arranged
substantially as described with reference to the accompanying drawings and for the
purpose specified.
