I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6 Bank Street, Man-
chester both in the County of Lancaster and 323 High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
The improved spirit, soldering-lamp, which forms the object of this invention,
is essentially characterised by a peculiar arrangement, which has for its object to
render entirely independent of one another the spirit reservoir, the burner, and
the tube containing the wick, which latter draws the spirit by capillary attraction
to the openings leading to the vapour chamber; this system having the notable
economic advantage of allowing any repairs, or other work, to be done to the
reservoir, to the central tube, or to the burner, without sacrificing one or other of
these parts, an inconvenience which it has been impossible to avoid hitherto in
this kind of apparatus, because these various parts were solidly attached one to the
other by brazing.
This method of arrangement also allows the jet of flame to be directed in any
suitable direction, as may be desired, as regards the reservoir or the handle, so
that the lamp may be employed in the most difficult positions.
In this improved arrangement, the central tube is made in one piece with the
part of the burner which constitutes the regulator, and with the vapour chamber.
to which the air jet is attached in the ordinary manner, and the whole is removably
connected to the top of the spirit reservoir into which the wick-tube is inserted
almost to the bottom, the wick being simply inserted with considerable friction in
the interior of the tube. In order to allow of its being removably connected
with the reservoir, an interior nut is brazed in the top of the latter, in which a ring
bolt is screwed, this latter moving freely on the tube. In order to form a tight
joint between these parts, there is formed with the perimeter of the tube a reversed
cone, and this cone is pressed under the action of the bolt on the sharp angle of the
turned-back edge of the fixed nut.. This fitting gives an hermetically tight joint.
The joint may be also obtained by means of two conical coinciding surfaces, or by
washering, but the conical joint on the sharp angle is preferable, as it works
faultlessly. In this way, as may be seen, the burner may be placed in such a way
as to direct the flame in any suitable direction, as regards the axis of the reservoir.
The vapour opening coming into the chamber, and emerging through the small
regulating hole, is inclined in such a way as to be directed on the angle of the
vapour chamber. In this manner, it does not pass in front of the microscopic hole
for allowing the vapours to pass into the nozzle, as such an arrangement would
deleteriously affect the good working of the lamp, and, on the other hand, nothing
prevents the easy insertion of a drill for boring.
A handle, arranged on the side of the reservoir, allows the apparatus with the
flame under pressure to be easily and conveniently handled, such an apparatus
forming, in the arrangement hereinbefore described, a tool of a perfection hitherto
unknown of its kind.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :―
The improved benzine, soldering-lamp, which forms the object of this invention,
is essentially characterised by a peculiar arrangement, which has for its object to,
render entirely independent of one another the benzine reservoir, the burner, and
the tube containing the wick, which latter draws the benzine by capillary attraction
to the openings leading to the vapour chamber; this system having the notable
economic advantage of allowing any repairs, or other work, to be done to the
reservoir, to the central tube, or to the burner, without sacrificing one or other of
these parts, an inconvenience which it has been impossible to avoid hitherto in this
kind of apparatus, because these various parts were solidly attached one to the
other by brazing.
This method of arrangement also allows the jet of flame to be directed in any
suitable direction, as may be desired, as regards the reservoir or the handle, so that
the lamp may be employed in the most difficult positions..
This invention is shown in the accompanying, drawings in which
Figure 1 is a vertical: section of the whole apparatus.
Figure 2 is a separate elevation of the burner with, the central tube and its mode
of attachment.
In this improved. arrangement, the central tube T is made in one piece with the.
part of the burner which constitutes the regulator R, and, with the vapour
chamber. C to. which the air jet is attached in the ordinary manner, and the
whole is removably connected to the top of the, benzine reservoir D into, which the
wick-tube.is. inserted almost to the bottom, the wick being simply inserted with,
considerable friction in the interior of the tube T. In order to allow of its being
removably. connected. with the reservoir D, an interior nut. E is brazed in, the top.
of the latter, in which nut. an annular bolt B.is screwed, this latter moving freely.
on the tube. In order to form a tight joint between these parts, there is formed
with the perimeter of the tube T a reversed cone c, and this cone is pressed under
the action of the bolt B on the sharp angle of the turned back edge.r of the.fixed
nut E. This. fitting. gives an hermetically tight joint. The joint may be also
abtained. by means of two conical coinciding surfaces, or by washering, but the
conical joint on the sharp angle is preferable, as it works faultlessly. In this way,
as may be seen, the burner may be placed in such a way as to direct the flame in
any suitable direction, as regards the axis of the reservoir.
The vapour opening L coming into the chamber C, and. emerging through. the
small regulating.hole is inclined in such a way as to be directed on the angle of
the vapour chamber C. In this manner, it does not pass in front of the microscopic
hole m for allowing the vapours to pass into the nozzle, as such an arrangement
would deleteriously affect the good working of the lamp, and, on the other hand,
nothing prevents the easy. insertion of a drill for boring.
This improved lamp is specially applicable for burning benzine, but any other
suitable material may be used.
A handle P,,arranged on the side of the reservoir, allows the apparatus with
the flame under pressure to be easily and conveniently handled, such an apparatus

page_text: forming, in the arrangement hereinbefore described, a tool of a perfection hitherto
unknown of its kind.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
:-
1. In soldering or blow-pipe lamps, the construction of the burner and of the
wick tube in such a way that they are entirely independent of one another and of
the spirit reservoir and so that they may be connected with the said reservoir in a
removable manner.
2. In soldering or blow-pipe lamps, the construction of the joint between the
central tube and the reservoir, characterised by a nut brazed into the top of the
reservoir and having an internal flange with a sharp edge, on which a cone on
the perimeter of the tube presses, this tube being screwed to the said flange of the
nut by means of an annular bolt turning freely on the central tube.
3. In soldering or blow pipe lamps, the direction of the vapour admission hole
into the chamber in such a way that it does not open opposite the opening for the
escape of the vapour to the burner.
4. The soldering or blow pipe lamp or apparatus as a whole substantially as
herein before described and shown on the accompanying drawing.
