IMPROVEMENTS IN SOLDERING IRONS HEATED BY A GAS JET OR FLAME
Year: 1885

page_text: I, GEORGE OULTON, of Stanley Street, Liverpool, in the County of Lancaster,
Lead Merchant and Brassfounder, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN SOLDERING IRONS HEATED BY A GAS JET OR FLAME
" to
be as follows:-
This invention refers to that class of soldering irons which are heated by a gas
jet or flame The gas is led through a pipe forming the handle which is connected
to the gas supply by a swivelling joint, in conjunction with a smaller pipe projecting
for some distance up the handle, forming with it a burner on the Bunsen principle
the air being admitted through holes in the handle, or the gas may be supplied
through a separate pipe. A connecting piece, preferably of T-shape, is attached to
the end of the handle, and to each end of this is attached a copper bit. These bits
may be of usual construction but I prefer to make each with a series of flutes,
holes, or channels so as to provide a larger surface for the flame to play upon and
to direct the flame to the end of the bit. The bits are screwed or otherwise
fastened and may be made interchangeable so that one of any required shape may
be applied. In the connecting piece is made, preferably in rings, a series of holes
through which the gas jet issues. The flame rising envelops whichever end is
held uppermost, and in a short time will heat it. The hot end may then be used
in the operation of soldering and while in use the other end, as it is turned up
being enveloped in the rising flame, becomes hot and ready for use as soon as the
other one becomes cool and so on, one end is continually being heated, whilst the
other is in use and becoming cool
Thus in the operation of soldering neither heat nor time are lost.
I prefer to make the implement with two bits forming with the handle a T but
more than two may be used if thought desirable and be made to project forward
or otherwise placed so that the rising flame will envelop one or more whilst one is
in use.

page_text: The construction here shown might, if desired, be altered by making a projection
on the bit I fit or screw into the side of the burner J. The copper bits may be
made of plane surface, but I prefer to make them fluted at the upper ends with a
series of flutes b, as thereby a greater surface is secured upon which the flame will
play. Instead of having the connecting piece or burner J as wide as shown, it
might be made narrower, and the two copper bits recessed at the sides which
approach each other, until the end of the flutings on one touched or almost touched
the other, the flame being made to issue out between the flutings.
For wedge shaped bits and others of large size the construction may be varied,
and the bits cast in one piece joined at the bottom. The burner is screwed into a
hole in the bottom, the end opening into the chamber formed between the bases
of the two bits. The flame from, the burner issues out between the bits and
surrounds them. A portion also passes through a channel cut from the interior of
each bit to the top.
When in operation, the implement is held with the pipe A horizontal, and with
the bits L approximating to the perpendicular, the gases issuing from the holes j in
the burner being ignited. The flame rising envelopes whichever of the bits is
uppermost. This when heated may be used in the operation of soldering, and
while in use the other bit as it is turned up, being enveloped in the rising flame
becomes hot and ready for use as soon as the other one becomes cool, and so on.
One bit is continually being heated while the other is in use and becoming cool.
Thus in the operation of soldering, neither heat nor time is lost.
I prefer to make the implement with two bits, forming with the handle a T, but
more than two may be used if thought desirable, and be made to project forward
or otherwise placed, so that the rising flame will envelope one or more while one
is in use.
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
1st. A soldering iron heated by gas, having two or more copper bits placed
opposite one another, or at such an angle that the flame rising upwards plays upon
the surface of one, and heats it, whilst another is in use in the operation of
soldering, substantially as described.
2nd. In a soldering iron heated by gas, the combination with the burner of a
copper bit having a number of channels at its broader end, which provide greater
surface of metal upon or around which the frame may impinge or play.
3rd. A. soldering apparatus having two or more bits attached or fitted at their
bases to a chamber or burner supplied with gas through the handle, and provided
with a series of holes from which a gas jet issues round the base of the bits,
substantially as and for the purposes described.
