PROVISIONAL SPECIFICATION.
Improvements in Lamps for Burning Inflammable Liquids.
We, JOHN COLE and JAMES EDWARD ZEALEY, both of 13, Camera Square,
Chelsea, in the County of Middlesex, do hereby declare the nature of this inven-
tion to be as follows:-
The object of this invention is to prevent explosions caused by the overturning
of the lamp.
The lower part of the wick is contained in a tube passing down into the oil
reservoir whilst the upper part is contained in the burner tube. Between this
reservoir and the burner tube is an air chamber through which the wick passes
uncovered so that if the lamp is overturned if any oil escapes from the reservoir
by flowing through the wick it stops in the air chamber and does not reach the
burner.
An extinguishing cap normally raised by a weighted arm is pivotted to a
sleeve surrounding the burner tube. If the lamp is overturned the sleeve is
turned by the weight until the latter is vertically beneath its pivot so bringing
the cap down onto the top of the burner tube and extinguishing the lamp, or the
overturning of the lamp may, by a weight or otherwise, raise a loose sleeve upon
the wick tube and extinguish the lamp.

Improvements in Lamps for Burning Inflammable Liquids.
We, JOHN COLE and JAMES EDWARD ZEALEY, both of 13, Camera Square,
Chelsea, in the County of Middlesex, 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 object of this invention is to prevent explosions caused by the overturning
of the lamp.
The lower part of the wick is contained in a tube passing down into the oil
reservoir whilst the upper part is contained in the burner tube. Between this
reservoir and the burner tube is an air chamber through which the wick passes
uncovered so that if the lamp is overturned if any oil escapes from the reservoir
by flowing through the wick it stops in the air chamber and does not reach the
burner.
An extinguishing cap normally raised by a weighted arm is pivotted to a

turned by the weight until the latter is vertically beneath its pivot so bringing
the cap
down onto the top of the burner tube and extinguishing the lamp, or the
overturning of the lamp may, by a weight or otherwise, raise a loose sleeve upon
the wick tube and extinguish the lamp.
The drawing represents a small hand lamp made according to our invention.
a is the oil reservoir and b the air chamber separated from a by a partition c
which may be flat or dished. d is the wick tube and e the burner tube. Thus
any oil which runs up the wick tube, if the lamp is upset, does not reach the
burner but flows into the air chamber b, whence it returns on righting the lamp
by the hole d¹ and the wick tube d to the reservoir. A small flange f is formed
at the base of the burner to prevent any oil which may run into the air chamber
from reaching the burner.
As an additional precaution we may provide a small shield such as d² at the
bottom of the wick tube which allows oil to pass sufficiently freely for the burner
but stops any large flow when the lamp is upset.
In order to extinguish the flame, if the lamp is upset, we provide an extinguish-
ing cap 9 on a weighted lever h, pivotted on an arm j carried by a sleeve k which
can rotate freely round the burner tube e so that if the lamp is tilted, the sleeve
rctates until the weight is vertically below the burner tube and the cap covers
the flame.
It is obvious that our invention applies not only to hand lamps such as that
shown but to various kinds of oil and spirit lamps and that the burner may be.
of any ordinary construction.
In order to permit any gas that may arise from the oil to escape we may pro-
vide a small hole in the filling tube.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. Enclosing the wick of a lamp in two tubes with a space between them to
allow of the escape of any oil or spirit which may run up the tube into a separate
chamber.
2. An extinguisher for lamps consisting of a cap on a weighted lever carried by
a pivot free to rotate round the burner tube.
3. Lamps as described and shewn in the drawing.
