An Improved Smoothing Iron Heated by Gas Generated from
Kerosene or other Oil or Spirit.
I, GEORGE POLL, of No. 56, Oxford Chambers, Bourke Street, Melbourne, in the
Colony of Victoria, Miner, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improved smoothing iron which is heated by the
combustion of gas generated from kerosene or other oil or spirit the conversion
of the oil being brought about by its being passed through a heated tubular coil
arranged within the iron.
I will now describe the invention aided by a reference to the accompanying:
sheets of drawings which illustrate it in
Fig. 1 by a part side view and a part longitudinal section.
Fig. 2 shewing a back view of the iron and with the oil reservoir in section.
Fig. 3 a front view of the burner, coils and cup.
Fig. 4 an enlarged sectional view of the burner and
Fig. 5 a cross section of the handle.
The iron proper is in the form of a hollow box A made the usual shape in plan
and provided with a chimney A' at its fore end whilst B is its handle and which is
coated with nonconducting material. At the back end of the iron is an oil supply
reservoir Chaving attached to its lower end and leading from it into the box a
copper tube or pipe C terminating in a double coil C. Said coil being prefer-
ably double with the inner return coil within an outer coil and having the end of
the outer tube attached at d to a Bunsen burner D, also the pipe C has a branch C³
leading from it at c to and entering the upper part of the oil reservoir C. Around
the plain part of the burner is a cup D in which to hold and burn methylated
spirit by the burning of which the coil is heated in the first instance prior to its
being placed in the iron in order to heat the coils to generate the oil gas. The
orifice d in the throat of burner is very small and in the tube or chamber leading
to it is a very fine gauze hood the purpose of which is to prevent the choking
of the burner.
Within the aforesaid oil reservoir C is a rod E having at its lower part a valve E¹
and said rod or spindle passes out through a screwed gland and stuffing box E
at top of reservoir in order to receive a key Es by which the flow of oil may be
regulated by the position in which the valve is placed, said valve within the reser-
voir having a small way e in it passing from its side down its centre to the pipe C¹
leading to the tube or coil. By having a pipe C3 as aforesaid connecting the gas
generating coil with the top of reservoir the flow of oil is assured by reason of the
gas pressure being upon it. At back of the hollow part of iron a hole is provided
through which to pass the said tubular coil C, the said cup D' fitting neatly in the
hole and forming a cover for it. C is a pipe provided with a screw cover or cap Ce
by the removal of which the gas blows out or escapes. The oil reservoir C is held
in position by a suitable catch F which grips the back vertical bar of the handle

page_text: and such reservoir and coil are made secure to each other and in such a manner
that they are separable from the box iron whilst a suitable capped supply hole C5
is provided in the top of the oil reservoir. The handle B is made in two parts
viza central bar and the asbestos coating b, the latter being asbestos fibre
held in position by a gauze covering and the former ba covering of sheet asbestos.
To use the iron the reservoir is first filled with oil preferably one half kerosene
and the other half benzine and the reservoir and coil being detached from the iron
proper the said parts are laid in such a position that the cup D is horizontal and
in it methylated spirit is placed and ignited in order to heat the coil and so con-
vert the oil in it into gas and which gas as it issues from burner D is ignited.
Then the coil and reservoir are placed at the positions shown in Fig. 1 in the iron
the issuin- gas heating the coil.as. well as heating the iron and the pipe leading
the gas pressure to above the oil in reservoir in order to ensure a constant supply
of oil to the gas generating tubes or coils.
"Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed. I declare that what I
claim is:-
1. A smoothing iron made of box form and provided with a chimney the back
of box having a hole through which to insert a coil or tube which is fed with oil
from an attached reservoir and said coil terminating in'a bunsen burner sub-
stantially as described and shewn in the drawings.
2. In a smoothing iron the combination of the reservoir as A tubular coil C
burner D, gas pressure return pipe C, cup D₁, valve E and their appurtenant parts
substantially as described and shewn in the drawings.
3. In a smoothing iron coating the handle with asbestos substantially: as:
described and shewn in the drawings.
4. The improved smoothing iron heated by gas generated from kerosene or other
oil or spirit consisting essentially of the box A, tubular coil C, burner D, cup: D'
reservoir C and return pipe C substantially as herein described and shown in the
drawings.
