PROVISIONAL SPECIFICATION.
Improvements in Soldering Irons.
J, GUSTAV ADOLF HARDT, of 11 Siousthal, Cologne on the Rhine, in the Empire
of Germany, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a soldering iron formed with or having attached thereto
a chamber or container into and from which fluid solder may be drawn and forced by
pneumatic action.
The soldering iron shewn in Fig. 1 of the accompanying drawing comprises a
soldering iron proper K (a flat or pointed iron), a handle or stem S and an air
chamber L. The iron proper K and air chamber are shewn in section.
The soldering iron K is formed with a space or chamber into which the hollow
stem or handle S fits air-tight, the other end of said handle or stem communicating
with a collapsible air chamber L, which may be constructed and arranged in any
suitable manner, provided its capacity is capable of being adjusted to the work to be
performed. At the lower end of the space or chamber x is a vertical or inclined
passage (o) extending to the outside of the iron. The handle may be made solid and
connection between the hollow soldering iron and the air-chamber be made in any
other suitable manner.
The method of using my improved soldering iron is as follows:-
:-
The air chamber is compressed or collapsed and whilst in this state the lower end
of the opening or passage (o) of the previously heated soldering iron is dipped into
the fluid solder. As soon as the pressure on the air chamber is relieved, this chamber
will expand, thereby causing a partial vacuum in the air chamber and the hollow
stem S(or other communicator employed between the air chamber and the soldering iron)
the result being that fluid solder will be sucked or drawn up into the hollow iron.
The quantity of solder thus sucked or drawn up may be sufficient for soldering a
number of places or seams. In using the soldering iron, the part thereof in which
the opening o is formed, is passed in the well known manner over the part or parts to
be soldered, the efflux of solder being regulated by varying the pressure on the air
chamber. As will be obvious any superfluous solder on the soldered joint may be sucked
up again into the chamber of the iron for subsequent use. Instead of a hollow iron a
massive or solid one may be used; thus an ordinary soldering iron may be converted
into a pneumatic one by fixing, for instance, the end of the tube S connected with
the air chamber, to the outside of the iron proper K as shewn in Fig. 2. In such a
case the end of the tube S which may be flattened as shewn performs the function of
the space or chamber and the opening or passage (o) shewn in Fig. 1.

Improvements in Soldering Irons.
I, GUSTAV ADOLF HARDT, of 11 Siousthal, Cologne on the Rhine, in the Empire of
Germany, Civil 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 relates to a soldering iron formed with or having attached thereto
a chamber or container into and from which fluid solder may be drawn and forced
by pneumatic action.

page_text: The soldering iron shewn in Fig. 1 of the drawing filed with my Provisional
Specification comprises a soldering iron proper K (a flat or pointed iron), a
handle or stem S and an air chamber L. The iron proper K and air chamber are
shewn in section.
The soldering iron K is formed with a space or chamber into which the hollow
stem or handle S fits air-tight, the other end of said handle or stem communicating
with a collapsible air chamber L, which may be constructed and arranged in any
suitable manner provided its capacity is capable of being adjusted to the work to be
performed. At the lower end of the space or chamber is a vertical or inclined
passage o extending to the outside of the iron. The handle may be made solid and
connection between the hollow soldering iron and the air chamber be made in any

The method of using my improved soldering iron is as follows:-
The air chamber is compressed or collapsed and whilst in this state the lower end
of the opening or passage (o) of the previously heated soldering iron is dipped into the
fluid solder. As soon as the pressure on the air chamber is relieved, this chamber
will expand, thereby causing a partial vacuum in the air chamber and the hollow
stem S (or other communicator employed between the air chamber and the soldering
iron) the result being that fluid solder will be sucked or drawn up into the hollow
iron. The quantity of solder thus sucked or drawn up may be sufficient for soldering
a number of places or seams. In using the soldering iron, the part thereof in which
the opening o is formed, is passed in the well known manner over the part.or parts
to be soldered, the efflux of solder being regulated by varying the pressure on the
air chamber. As will be obvious any superfluous solder on the soldered joint may be
sucked up again into the chamber of the iron for subsequent use.
Instead of a
hollow iron a massive or solid one may be used; thus an ordinary soldering iron may
be converted into a pneumatic one by fixing for instance, the end of the tube S con-
nected with the air chamber, to the outside of the iron proper K as shewn in
Fig. 2. In such a case the end of the tube S which may be flattened as shewn
performs the function of the space or chamber & and the opening or passage (o) shewn in
Fig. 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. For soldering a hollow soldering iron having suitably connected to it an air
chamber that is collapsible or capable of having its capacity readily altered so that it
may be made to cause fluid solder to enter a hollow or space formed in the
soldering iron, and to afterwards force such solder out of the hollow or space by
pneumatic action.
2. The combination of a solid soldering iron and an air-chamber that is collapsible
or of variable capacity for the purpose referred to in claim 1.
