Improvements in Petroleum Heating Apparatus, suitable for
Heating Soldering Irons and for other purposes.
I, JASPER WETTER, Patent Agent, of 433, Strand, London, 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 relates to petroleum heating apparatus suitable for heating
soldering irons. The object is, to construct a heating apparatus, which will
produce very high temperatures with relatively low consumption of fuel, and
which will enable an operator to work continuously by means of two heating irons ;:
also to provide that the size of the flame can be easily regulated, the wick is only
slightly exposed to charring, and the apparatus may be used at will for heating
only one soldering iron or for heating two at the same time.
In further describing the invention, reference will be made to the accompanying
drawings, of which
Fig. 1 is a vertical section and Fig. 2 a plan of a heating apparatus embodying
the present invention.
Fig. 3 is a vertical section and Fig. 4 a horizontal section of a similar apparatus.
in a different position.
Fig. 5 is a vertical section at a right angle to that shown by Fig. 3.
Figs. 6 to 9 represent details of construction on a larger scale.
This apparatus comprises an oil receptacle mounted on a hollow stand a, an
external wick tube mounted upon the oil receptacle, and an internal wick-
tube d which passes through the oil receptacle and is capable of sliding up
and down, the said tube being guided by a sleeve e fixed to the oil receptacle.
In order, that the upper part of the wick tube d may be wide enough, and have
a suitable guide, it is provided with a collar d' which fits over the guide.
sleeve. By forcing the wick tube d upward, as shown by Figs. 3 and 5, the-
wick tube is made to cover a greater part of the inner wick surface, and the size-
of the flame is consequently reduced. If the wick tube is raised beyond a certain
limit, it will extinguish the flame; because the wick does not project over the
external wick tube. If, on the contrary, the tube is drawn downward, as.
shown by Fig. 1, the flame will increase in size, because the inner surface of the
wick will become free.
For shifting the sleeve d longitudinally, as described, I employ a bar, which is
fixed to the same.
The bar is guided in a pair of inclined slots, one of which is formed in a guide-
sleeve e and the other in the hollow stand or frame a.
If now the sleeve d is turned by means of the said bar f, the oblique slot of the
guide sleeve will cause the inner wick tube d to rise or to fall, thereby regulating-
the flame or extinguishing it, in the manner described.
In the interior of the wick tube, there is mounted a tuber for supplying com-.
pressed air, which may be provided by a fan or other appliance, and serves to
produce a very intense flame.
The vertical air tube ar nozzle communicates with a horizontal feed tube .
and is provided at its lower end with a stopcock / arranged in such a manner, that
it will open or close communication with the tuber according to the direction in.
which the tube is turned on its axis.
If the inner wick tube is raised, by turning it on its axis, it will at the same.
tine close the stopcock.

page_text: The air supply pipe is connected with the inner wick tube d in such a manner,
that it will turn with the same, but not share its up and down motion. For this
purpose, the tube is provided with a pin s (Figs. 6-9) which is guided in a
longitudinal groove i formed on the inside of the wick tube.
The upper part or lamp casing n, which is mounted on the oil receptacle, has
perforations o, o, through which atmospheric air reaches the flame. This upper
casing has a suitable aperture, through, which the lamp can be ignited, and which
is ordinarily closed by a flap g.
If the wick has become charred, by long use, the casing n is lifted off, the wick
is lifted by means of a pointed instrument or by hand, and then trimmed.
The upper part of the casing n is cylindrical and contains a holder / for
the soldering irons, which holder is adapted to turn on a pivot, placed in the
axis of the casing n and fixed on a bracket extending diametrically across
the same.
The holder contains two openings adapted to receive two soldering irons, so that
the same can be heated simultaneously. These openings may be arranged as shown
by Fig. 4, that is to say, they may be separated by a vertical partition which is
placed vertically over the flame and divides the same (Fig. 5) if it is desired to
heat the two irons at the same time. For heating only one iron, the holder n is
turned, so as to place only, one of the openings over the flame.
Having now particularly described and ascertained the nature of the said inven-
Lion, and in what manner the same is to be performed. I declare that what I
claim is:
1. In petroleum heating apparatus, a burner having an inner and an outer wick
tube arranged and guided substantially as described so, that the inner wick tube
can be raised and lowered and thereby the wick more or less exposed, in order to
regulate the size of the flame.
.
2. In petroleum heating apparatus, a burner having an axial air tube or nozzle »
and means for supplying the same with compressed air, in order to increase the
heating effect, substantially as described.
3. In petroleum heating apparatus, a device for raising and lowering the inner
wick tube and simultaneously reducing or increasing the supply of compressed air
to the axis of the burner, substantially as described.
4. In petroleum heating apparatus for soldering irons, a moveable holder
having a pair of openings for the soldering irons, the said holder being mounted
over the burner in such a manner, that by turning the holder, either or both of two
soldering irons may be exposed to the flame, substantially as described.
