Improvements in Lamps or Burners for Heating Soldering Irons,
Removing Paint, and for other uses.
1, WILLIAM PULLEN of No. 17 Lime Grove, Moseley Road, Birmingham in
the County of Warwick, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows :—
or
This invention relates to the improvements hereinafter described in soldering-
irons thereby such irons are made self heating by the application of a vapour
burner adapted for use in connection with hydro-carbon fuel preferably naptha
benzaline arranged and combined to produce intence heat to the surface of the
copper bit of the soldering-iron. Heretofore soldering-irons particular those
adapted for plumbers or open air use have had to be heated by means of coke or
other fire which necesetates the loss of time and trouble in preparing them
for use.
By my invention I am enabled to avoid these objections and to provide a
soldering-iron with a burner by which it may be heated to any degree of heat
without any mechanical force draught, the said burner is arranged to give out a
steady and constant flame of high temperature which may be easily regulated.
My said invention may also be used for a painters torch for burning off paint,.
or a lead burner, or soldering tool, or for heating and fusing metals and for
various other purposes to which a blowpipe is generally applied.
My invention consists essentially of a vessel or container, for containing or
holding naptha or the like, which may in some cases form part of the handle of
the soldering-iron, or it may be a seperate vessel attached to the handle of the
soldering-iron.
I will describe a soldering iron in which the vessel forms part of the handle
and consists of a metallic tube into which is fitted an inner tube of much less
diameter, also less in length than the outer tube. The connection between the two
tubes is closed at one end a little below the edge of the outer tube leaving a neck or
cup encircling the small tube for the purpose hereinafter described. The bottom part
of the handle or outer tube, is provided with a screw cap. I furnish the two tubes
with a wick or other fibre material which I attach to a twisted wire or a tube
of small diameter and insert the same in the small or inner tube of the handle by
removing the cap and pressing it therein the said wick being long enough to reach
the top of the inner tube and the outside thereof, that is to say, passes up and
down in a tube in the two ends occupying the space between the two tubes.
The inner tube projects a little beyond the edge of the outer tube and is screwed
into a regulating valve which terminates into a bulbous shaped opening provided
with a burner having a very small orifice or orifices to the outside of the burner, in
the bulbous opening of the valve is secured a cylindrical tube furnished with a
series of perforations for the admission of air thereto.
I also provide a movable cylindrical tube to fit externally the aforesaid tube to
regulate the admission of air or I may make a movable wire gauze cylinder for
regulating the admission of air. Or I may make two cylindrical tubes, one placed
inside the other and a little less diameter in which case both may be provided with
openings or air passages in different positions to each other.
To the cylindrical tubes aforesaid I attach by means of a screw or suitable joint,
a copper bit which constitutes for the soldering iron. I may pierce holes in the

page_text: wide part of the copper bit. When it is desired to heat the soldering iron, the
screw cap is removed from the handle or outer tube-which is filled with naptha
which is absorbed by the wick. A little naptha is also poured into the cup at the
opposite end of the handle which is ignited, for the purpose of warming the upper
part of the inner tube in the valve. When these have become warm the valve is
opened slowly, the vapour from the naptha will be admitted at the opening of the
burner and will ignite, giving off a flame of high temperature at the hole or holes
in the cylindrical tube near the copper bit and also the holes in the copper bit.
When it is desired to convert the soldering-iron into a plumbers or painters tool,
such for example as a burning off torch or a lead burner it is only necessary to move
the copper bit by means of the screw or detachable joint aforesaid, when by applying
the light to the orifice, a flame of high temperature will emit. The flame may be
regulated to any degree by means of the valve.
My invention may be modified in any detail as may be necessary, to carry the
same into effect, without departing from the nature thereof.

Improvements in Lamps or Burners for Heating Soldering Irons,
Removing Paint, and for other uses.
I, WILLIAM PULLEN, of 11, Ashted Row, Birmingham, in the County of
Warwick, late of No. 17, Lime Grove, Moseley Road, Birmingham, aforesaid,
Mechanical Engineer, do hereby declare the nature of this invention aud 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 the herein-described improvements in spirit lamps or
burners for heating soldering irons, removing paint and for other uses such as for
burning lead when seaming the same, or as a soldering tool for making plumbers'
joints, or for heating and fusing metals and for various other purposes to which a
blow pipe is generally applied. When the said lamps or burners are constructed
according to this invention they will give out a steady and constant flame of high
temperature which may easily be regulated.
I will describe my invention by referring to the accompanying drawings on
which Fig, 1 is an elevation and Fig. 2 is a sectional elevation of my invention
constructed as a soldering iron; Fig. 3 is a cross section of the same on line X X
of Fig. 2; Fig. 4 is a cross section on line Y Y of Fig. 2 and Fig. 5 shews a slightly
modified form of my invention.
The same letters of reference indicate the same or corresponding parts in all the
figures.
In carrying out my invention I provide a vessel or container A for containing
naphtha or other like liquid fuel the said vessel A forming part of the handle of
the soldering iron and by preference constructed of an outer metallic tube A into
which is fitted an inuer tube B of much less diameter and also somewhat shorter than
the outer tube A.
This tube B passes through and is fixed in a cap C which closes one end of the
tube A and is formed with a neck or cup c¹ encircling the small tube B for the
purpose hereinafter described. The other end of the outer tube A is provided
with a removable screwed cap D. The tubes A B contain a wick E or other like
fibrous material which is attached preferably to a twisted wire F which is inserted
in the smaller tube B as shewn in Fig. 2, the wick E being long enough to reach

page_text: to the top of the inner tube B and fill the annular space between the tubes A
and B. The upper end of the inner tube B which projects a little beyond the top
of the outer tube A is screwed at b'into the regulating valve G which terminates in
a bulbous shaped part g' provided with the burner H having a very small orifice h¹
for the vapour to pass through to form the flame. The upper end of the tube B is.
closed by the plug N in which there are holes n³ n³ through which the spirits can.
flow to the burner H and in the middle of the plug N there is a boss or pommel y²,.
which when the tube B is screwed tight into the valve G, closes the passage 93 therein
and stops the flow of the naphtha to the burner A but when the tube B is turned in
the opposite direction so as to be slightly unscrewed, the pommel or valve g' opens
the passage so that the naphtha can flow to the burner H. On the bulbous
part gl there is screwed the cylindrical tube I furnished with series of per-
forations for the admission of the air thereto. Fitting on the ribs 2 formed.
externally on the tube I there is a short movable cylindrical tube J which can be
moved up and down the tube I so as to regulate the admission of the air through the
openings and also form a windguard when required to prevent the wind blowing
directly into the holes i and -blowing out the flame at the burner H. Or instead
of the tube J, I may provide a movable wire gauze cylinder on the outside of the
tube I for regulating the admission of air. Within the tube I there is fixed
another tube K of smaller diameter and of a gradually contracted area towards the
top through which the flame issues, this tube K being also made with air
inlet openings k² corresponding with the inlets i. To the upper end of the tube L
the copper bit L is removably fixed by any suitable means as by fitting therein and
being secured by the small screw . The copper bit L may be pierced with
holes as shewn in Fig. 1 and 2 for the heated air and flame to pass through, or
as shewn in Fig. 5, the copper bit L may be made without the holes 12 and in this
case the holes have to be provided in the upper part of the tube I for the flame
and heat to pass through.
By first removing the screwed cap D from the bottom of the outer tube A
the latter can when inverted be filled with naphtha or other suitable liquid fuel
which is absorbed by the wick E. The cap is then replaced. Before heating the
copper bit L a little naphtha has to be poured into the cup c¹ and ignited for the
purpose of warming the upper part of the inner tube B in the valve G. When
these have become warm the valve G is opened slowly by turning the tube B so as
to allow of the vapour of the naphtha passing through the holes n² n³ and the
passage to the burner H and through the opening therein where the vapour
will ignite and give off a flame of high temperature at the hole or holes in the
cylindrical tube near the copper bit Land also through the holes when the latter
are employed.
When it is desired to convert the soldering iron into a plumbers' tool for burning
lead or for making plumbers' joints or for heating and fusing metals or for various
other purposes to which a blow pipe is generally applied, or as a painters' burning
off torch it is only necessary to remove the copper bit L when a flame of high
temperature will issue from the end of the tube I. By means of the valve G the
flame may be regulated to any degree.
Instead of the inner contracted tube K being fixed to the upper part of the
valve G as shewn in Fig. 2 this part K with the contracted outlet k¹ may be fixel
to the tube I as shewn in Fig. 5 at some little distance above the air inlets ¹ thus
somewhat simplifying the arrangement.
Instead of employing the valve G as shewn in Figs. 1 and 2 for regulating the
flame, I may employ any other kind of valve or cock such for instance as an
ordinary plugcock or a screw down valve as shewn by Fig. 5 where the passage
of the spirit from the tube B to the cavity g¹ is regulated by the ordinary screw
down valve O.
Instead of using the twisted wire F with the wick E as shewn in Fig. 2 I may
(see Fig. 5) substitute a small tube P for the wire F said tube being split or
otherwise formed with prongs p¹ p² at one end to engage with the wick and force

page_text: it up the tube B. This small tube P is really preferable to the wire F as the
tube P assists in leading the spirits towards the burner H and the heated end of
the tube B.
The accompanying drawings illustrate what I consider the best method of
carrying out my invention but it is to be understood that my invention is not
limited to the precise details shewn.
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. In a lamp or burner for heating soldering irons removing paint and for
various uses such as heating and fusing metals, the combination with the tubular
spirit container F of the smaller tube B fixed and protruding therein and the
wick E secured to and surrounding the small tube P so as to fill the tube B and
the annular space around the same and absorb the oil and lead the same towards
the burner substantially as described.
2. In a lamp or burner for heating soldering irons or for removing paint or for
various uses such as heating or fusing metals, the combination with the container
for the spirits, of the tube B fixed thereto, a valve fixed to the tube B for
regulating the flame, a burner fixed to said valve and made with a very small
orifice such as h¹ for the spirit vapour to pass through, the outer perforated tube
such as I surrounding the burner and provided with inner tube K made with
contracted outlet k for increasing the intensity of the flame, the end of said outer
tube being adapted to fix to the copper bit of a soldering iron so as to be heated
by the flame, all substantially as set forth and shewn.
3. In a spirit lamp or burner for heating soldering irons or for removing paint
or for various uses such as beating and fusing metals, the combination with the
perforated tube which surrounds the burner of the air regulator J adapted to slide
on the ribs of the said tube and form a wind-guard to the flame, substantially as
set forth and shewn.
4. In a spirit lamp or burner for heating soldering irons or for removing paint
or for various uses such as heating and fusing metals, the construction and
arrangement of the valve for regulating the supply of spirits to the burner by
the turning of the handle or spirit containing vessel relatively to the burner
substantially as hereinbefore set forth and shewn in Figs. 1, 2, 3 and 4 of the
drawings.
5. The combination and arrangement of parts constituting the improved spirit
heated soldering iron hereinbefore described and illustrated by Figs. 1, 2, 3, and 4
of the accompanying drawings; also the modified arrangement herein described
and illustrated by Fig. 5.
