PROVISIONAL SPECIFICATION.
Improvements in Soldering Irons.
WILLIAM MORRISON SIMPSON 58 Elphinstone Road Hastings Gentleman do
hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction and arrangement of soldering
irons, so that they may be conveniently heated by means of ordinary coal gas, and
the same is carried out in the following manner.
I provide a bit or bolt piece having a central hole for the purpose of receiving
the end of the handle, and of a suitable depth. The outside of this bit is corrugated
a desired distance, along the same thus forming a series of flanges on the same.
At the bottom of these recesses a convenient number of holes, or slits are formed
which communicate with the central aperture in the bit.
The handle is formed of a piece of tube of suitable dimensions, to one end of
which the bit is screwed, the other being connected to the gas supply & projects
from the end of a wooden hand piece, through which it passes. Between the end of
the bit, and handle, preferably close to the handle, an ordinary Bunsen burner
is inserted, consisting of a small jet, blowing centrally along the inside of the
handle, and supplied with air in the usual manner. It will be seen that by con-
necting the end of the projecting tube with the gas supply, and igniting the gas
which issues from the orifices in the bit, the same can be readily heated aud
maintained at a desired temperature.

Improvements in Soldering Irons.
I WILLIAM MORRISON SIMPSON of No. 58 Elphinstone Road Hastings in the
County of Sussex Gentleman 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 has for its object the construction and arrangement of soldering
irons so that they may be advantageously heated by means of ordinary coal gas,
and the same is carried out in the following manner.
provide a metal bit or bolt-piece, preferably of copper, having a central hole
for the purpose of receiving the end of the handle, and of a suitable depth.
The outside of this bit is corrugated a desired distance along the same, thus
forming a series of flanges which serve the purpose of collecting and storing heat
when the gas is ignited as hereinafter mentioned.
At the bottom of the recesses formed by the flanges I provide a convenient
number of holes or slots in such a manner that the gas shall issue from the under
side of the bit, when in use. These slots or holes communicate with the central
aperture in the bit.
The handle is formed of a piece or pieces of tube of suitable dimensions, to one
end of which the bit is screwed, the other end being connected to the gas supply,
and projecting from the end of the hand piece, through which it passes.
Between the end of the bit and the handle an ordinary "Bunsen
nserted, consisting of a small jet blowing centrally along the inside of the handle,
and supplied with air in the usual manner.

page_text: It will be seen that by connecting the end of the projecting tube with the gas
supply and igniting the gas which issues from the orifices in the bit the same can
be readily heated and maintained at the required temperature.
In order that my invention may be fully understood I herewith append a
drawing illustrating it; A representing the hollow bit with heat collecting flanges,
and showing transverse slots underneath; B Bunsen tube; C air inlet with gas jet
shown inside; D gas tube in which gas jet is fixed; E hand piece; F connection
to gas supply.
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. The improved form of soldering iron as hereinbefore described and illustrated
by the accompanying drawing.
2. In a gas heated soldering iron, the use of flanges for collecting and storing
heat, constructed arranged and operating as and for the purposes set forth.
3. In a gas heated soldering iron, the use of holes or slots in the recesses between
the flanges, and on the underside of the bit, as and for the purposes set forth.
Dated this 13th day of July 1891.

Applicant.
