(A communication by ANDREAS GULBRANDSEN HOVDE, of Honefos, in the Kingdom
of Norway, Watchmaker.)
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.E.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118 New Street, Birmingham in the County of
Warwick and 322 High Holborn in the County of Middlesex, Civil Engineer, 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:
The object of this invention is to provide certain improvements in the usual
petroleum-burners, by aid of which the conduction of heat from the upper part of
the burner to the lower part is essentially reduced, for the purpose of preventing
explosions, and whereby also a new and simple extinguishing device is provided.
According to this invention the wick tube is made in two separate parts, of
which the upper part is made separately and rests only by aid of its weight on
the lower part of the tube, which is fastened to the burner. In this way there is
provided a joint which interrupts the heat conduction from the upper metallic part
of the wick tube to the lower part of the wick tube and the burner, the lower
part of the tube being in this way only very little heated.
By connecting the upper separate part of the wick tube with a suitable raising
device, this upper part of the tube may be raised above the wick, and the flame
be thus put out. The above improvements may be employed in flat as well as in
round burners.
In the accompanying drawings the invention is shown applied to a round
burner.
Figures 1 and 2 are vertical sections through the burner, and
Figure 3 is a horizontal section through the same.
A. and A¹ are the inner and the outer lower parts of the wick tube respectively.
B and B are the corresponding upper loose parts of the same, respectively, these
parts being shown in an elevated position. C is a tube enclosing the wick tube,
and forming the connection between the stationary, parts of the same and the
external parts of the burner.
The raising and lowering of the wick tube part B B' may be effected for instance
by aid of a lever E pivoted at F and embracing with its forked end G a pin H
placed at the lower end of the tube B, and which is also intended to form an
interior limit for the open space between the upper and the lower part of the wick
tube.
To facilitate the handling of the lever E, it may be connected with a swinging
lever or frame L, pivoted to pivots K and the one branch of which is movable in
slot M. of the said lever.
The whole of the lever E may also be placed within the burner head, so as to be
invisible.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim, is,
1. In a petroleum-burner, a wick tube consisting of a lower part, which is
fastened to the burner, and an upper, loose part, for the purpose of diminishing the
conduction of heat to the lower parts of the burner, and affording a means for
extinguishing the lamp by raising the upper part of the wick holder, substantially
as herein before described.
2. A lamp burner provided with a detachable upper wick tube and means for
elevating the same, consisting essentially in a lever pivoted to the burner and
engaging with its inner end a pin fastened to the detachable part of the wick
tube, substantially as herein before described.
