AN IMPROVED GAS-
led the 2nd January 1880, and dated the 4th July 1879.
PROVISIONAL SPECIFICATION left by the said Adalbert Leopold Vángel at
the Office of the Commissioners of Patents on the 4th July 1879.
ADALBERT LEOPOLD VÁNGEL, of Vienna, in the Empire of Austria-Hungary,
Manufacturer. "AN IMPROVED GAS-SOLDERING IRON WITHOUT AIR-BLAST."
This Invention has for object to produce a handy soldering iron or tool to be
heated by gas flame without an air blast, the required degree of heat being obtained
and regulated by the admission of air into a metallic tube, wherein it is mixed with
the gas, which may thus be consumed without smoke and soot, because the oxide of
carbon in the gas can be entirely converted into carbonic acid by the admission of
air. By these means the soldering iron may be uniformly and intensely heated in
a shorter time than soldering tools as heretofore usually employed.
The nature of the Invention will be readily understood from the following
description, reference being had to the accompanying Sheet of. Drawings, which are
given by way of illustration, and in the several Figures whereof the same letters of
reference are used to denote corresponding parts.
Referring to Fig. 1, a, a, are the iron or steel bits of the soldering iron or tool,
which can be unscrewed and' easily replaced by bits of other shapes; b is a metallic
casing enclosing and sliding over the gas-burning tube c, and provided with oblique
or other shaped incisions or holes d for the admission of air; e is the inlet pipe for
the gas, which pipe is at g. connected with an elastic tube at the end of the
handle g¹.
In the front or fore part of the gas pipe is a small hole f through which the gas
rushes into the burner, where it mixes with the air and ignites, producing a
powerful flame superior to those obtained by the use of a blast, as heretofore
usual.
The employment of two bits, as shown in Fig. 1, instead of 1 only, will enable
soldering to be carried on in a uniform and continuous manner without interruption
or inconvenience to the workman, as whilst one bit is in use the other will be heated
by the flame, which has an upward tendency.
Figures 2 and 3 show modifications of my soldering iron or tool with one bit.

by the said Adalbert Leopold Vángel in the Great Seal Patent Office on the 3rd.
January-1880..
ADALBERT LEOPOLD VÁNGEL, of Vienna, in the Empire of Austria-Hungary,
Manufacturer. "AN IMPROVED GAS-SOLDERING IRON WITHOUT AIR-BLAST."
This Invention has for object to produce a handy soldering iron or tool to be
heated by gas-flame without an air blast, the required degree of heat being obtained
and regulated by the admission of air into a metallic tube, wherein it is mixed with
the gas, which may thus be consumed without smoke and soot, because the oxide of
carbon in the gas can be entirely converted into carbonic acid by the admission of
air. By these means the soldering iron may be uniformly and intensely heated in
a shorter time than soldering tools as heretofore usually employed. The bits may
be of any required shape.
Referring to Fig. 3, a, a, are the iron or steel bits of the soldering iron or tool,
which can be unscrewed and easily replaced by bits of other shapes.
b is a metallic casing enclosing and sliding over the gas burning tube c, and
provided with oblique or other shaped incisions or holes d for the admission of air;
e is the inlet pipe for the gas, which pipe is at g connected with an elastic tube at
the end of the handle g¹.
In the front or fore part of the gas pipe is a small hole f, through which the gas
rushes into the burner, where it mixes with the air and ignites, producing a
powerful flame superior to those obtained by the use of a blast, as heretofore
usual.
The employment of two bits, as shewn in Fig. 3, instead of one only, will enable
soldering to be carried on in a uniform and continuous manner, without interruption
or inconvenience to the workman, as whilst one bit is in use the other will be
heated by the flame, which has an upward tendency.
Fig. 1 and 2 shew modifications of my soldering iron or tool with one bit. The
inlet pipes may be made of brass or of steel.
Fig. 4 illustrates a modification in which the bit is adjustable, so that the degree
of heating may be regulated. In this purpose the burning tube c has formed on it
a screw thread c'; c² is a nut or tube with an internal screw thread. By turning
the handle it will be seen the distance of the bit from the burner may be varied
at will.
When a large soldering iron or tool is required I construct it with two or more-
burning tubes connected together as represented by way of example in Fig. 5 and 6,
which shew a tool with two burning tubes c, c, held together by a coupling frame j,
or a similar arrangement.
Any kind of combustible gas may be used for heating my improved tools.
Having described the nature of my said Invention, and explained the manner of
carrying it into practical effect, I would have it understood that what I consider
to be novel and original, and therefore claim as secured to me under the Letters
Patent herein before in part recited is,--
I. The combination with a soldering bit of a tube with a hole fƒ for admitting gas
and other holes d for admitting air, regulated by a sliding case b, so as to dispense
with an air blast, substantially as hereinbefore described and illustrated.

page_text: II. The improved soldering irons or tools without, air blast constructed and
arranged as herein before described, and shewn respectively in Fig. 1, in Fig. 2, in
Fig. 3, in Fig. 4, and in Figs. 5 and 6 of the Drawings.
In witness whereof, I, the said Adalbert Leopold Vangel, have hereunto set my
hand and seal, this Thirtyeth day of December, in the year of our Lord
One thousand eight hundred and seventy nine.
ADALBERT LEOPOLD VÁNGEL. (L.S.)
