IMPROVEMENTS IN GAS SOLDERING IRONS
Year: 1880

page_text: LETTERS PATENT to Louis Quesnel, of Paris, in the Republic of France,
Mechanician, for an Invention of "IMPROVEMENTS IN GAS SOLDERING
IRONS."
PROVISIONAL SPECIFICATION left by the said Louis Quesnel at the Office
of the Commissioners of Patents on the 19th April 1880.

MENTS IN GAS SOLDERING IRONS."
" IMPROVE-
This Invention relates to a construction of gas soldering iron, in which the heat
is produced. without requiring a supply of air under pressure, and the tool heated
by the flame can be readily adjusted to suit different kinds of work. The handle
of the instrument is tubular and has at its end a nozzle to which is attached a flexible
or other gas pipe. The stem of the instrument is also tubular. Within the stem
there is a central orifice by which the gas supplied through the handle issues in a jet.
Air enters the tubular stein by lateral orifices surrounding the jet, which orifices can
be adjusted by a sleeve fitted to slide or turn on the exterior of the stem. The mixed
gas and air flow along the stem to its open end where the mixture is ignited,
producing a powerfully heating flame as from a Bunsen burner. On the end of the
stem is fixed a fork piece, in an eye of which the soldering tool is fixed by a setting
screw, the gas flame within the fork playing upon the side of the tool. By slacking the
setting screw the soldering tool can be readily removed from the eye of the fork,
and another tool of shape suited to the work can be put in its place and secured by
tightening the screw.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a front view and Fig. 2 a longitudinal section of a gas soldering iron
according to my Invention. The handle A terminates in a nozzle a, by which it is
connected to a flexible gas pipe. Its tubular interior B terminates in a jet orifice b
within the tube C, which has several lateral orifices c, c, for admitting air to produce
a flame at c. On the tube C is screwed a saddle D open in the middle for access of
air to the flame at c¹. In the upper part of the saddle the soldering iron N is secured
by a pinching screw m pressing it against the crossbar d of the saddle. It is of
advantage to fit on the tube Ca sleeve, indicated by the dotted lines M, and having
through it orifices n. By turning this sleeve more or less round so as to bring the
orifices n and c more or less into correspondence the admission of air to the gas
can be regulated.
Having thus described the nature of my Invention and in what manner the
same is to be performed, I claim,-
The construction of gas soldering iron, substantially as herein described with
reference to the accompanying Drawings.
In witness whereof, I, the said Louis Quesnel, have hereunto set my hand
and seal, this Twenty eighth day of August, in the year of our Lord One
thousand eight hundred and eighty.
