Gas Soldering Apparatus, with a Longitudinal Burner.
I, GUSTAV KETTMANN, of 119--120, Wilhelm Strasse, Berlin, S.W., 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 consists of a gas soldering apparatus with a longitudinal burner,
provided with a rectangular soldering iron or "bit," which presents a large surface
for contact with the flame of the burner, so as to make good use of the heat given
out by the burner and thus heat rapidly the said soldering iron of the apparatus.
I will now describe the invention with reference to the accompanying drawings
in which:-
Fig. 1, is a side elevation of the apparatus.
Fig. 2, is a sectional elevation of the same.
Fig. 3, is a view in elevation of the back of the burner.
Fig. 4, is a plan view of this burner.
Fig. 5, shows a modification of the gas and air tube.
The apparatus comprises a soldering iron a bent to a right angle, both ends of
which are utilised. It is connected by a bolt c and a nut d to a supporting rod b
resting by its lower end in a socket c attached to the sleeve f. Said rod slides in
the aperture made in e and can be fixed therein in any position by means of the
screw 9. The inner part of the sleeve f. bears a thread, and at one end of the
sleeve there is screwed a tube h, the top part of which is in the shape of a
spherical cap. This tube, which is parallel with the lower part of the soldering
iron is provided with a slot m. This slot is prolonged through the spherical cap
as shown in Figs. 3 and 4.
At the other end of the sleeve of a tube i is screwed, said tube forming a pro-
longation of the tube h. The lower extremity of the tube is screwed into a
socket; the cylindrical sides of which are provided with openings o.
On the lower part of the socket ja cylindrical nipple k is screwed provided with
a central tube tapering from the bottom upwards, and with a small aperture at
top. Said nipple is screwed in a handle, which has a central tube p, forming a
prolongation of the central tube of the nipple k.
At the lower part of the handle / is fixed a tube », provided with the usual enlarge-
ment allowing this tube to be connected with any elastic tube in communication
with a gas supply pipe.
The mixing of the gas and air may be effected according to any ordinary method
In the one shown in Fig. 5, the tube i runs up to the end of the handle 7, at
which point it is divided into two tubes, one for the gas and the other for the
air, which thus enter the handle together and form the mixture in the tube i.
In the arrangement shown in Fig. 2 the gas intended for heating the solder-
ing iron arriving through the tube, escapes with great speed through the
upper orifice of k, and carries along with it a certain volume of air entering the
socket through the openings o, thus forming a Bunson burner. The mixture
burns at the orifice of the tube .h, which constitutes the burner. The flame,

page_text: which is produced over the entire length of the slot m, envelopes the lower part
of the soldering iron almost completely and in the whole of its length, and also
surrounds a portion of the upper part of said iron. The hottest zone of the flame
possesses, by reason of the arrangement of the burner about the same shape as
the iron and covers.a large part of its surface.
The iron is heated rapidly and the flame is utilised in an economical manner.
The arrangement of the supporting-rod b allows the position of the upper part
of the iron to be regulated in regard to the flame of the burner, and the angular
shape of the iron allows either of the ends to be made use of.
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:
A gas soldering apparatus, consisting of a longitudinal burner and a rectangular
bit a large surface of which can be placed in contact with the flame of the
burner so to make good use of the heat of the burner, the said apparatus being
characterised by a soldering-iron or "bit" shaped as a right angle, both ends
of which can be utilised, said "bit" being fixed by a bolt to a supporting-rod b,
which rests upon the socket e of a sleeve f, in which socket the rod may be moved
vertically and maintained in any desired position by means of the screw g; also
by a tube screwed on the sleeve f, the upper part of which tube is a spherical
'cap provided with a longitudinal slot m extending right over the spherical cap;
also by a tube screwed on the sleeve as a prolongation of h, also by a socket j
with apertures for air and in which is screwed the tube h with a nipple-k provided
with a central opening tapering towards the top for admitting gas; also by a
handle 7, provided with a central tube through which the gas arrives and with
an enlarged end for connection with air elastic tube, substantially as herein
described and set forth.
