PROVISIONAL SPECIFICATION.
An Improved Safety Lamp for Use with all kinds of Paraffin
or Kerosene Burners for Hand, Table, or other Moveable
Lamps.
I ALFRED JOHN STONELY of 28 Uridge Crescent Tonbridge Kent Joiner
do hereby declare the nature of this invention to be as follows:-
This invention relates to a lamp for use with paraffin or kerosene lamps and is
adapted for use with any kind of hand, table or other moveable lamps used for
lighting purposes and for any size or description of wick round central draught or
any flat wick from one eigth of an inch upwards in use or used for lighting
purposes.
The lamp may be made of brass or other suitable metal and of any height
either hand table or pedistal lamp as the circumstance of the case may require.
The lamp may be made with a meta! base at bottom to the inside of which I
securely fix two circular discs or other shapes as the pattern of the base may
suggest with a space between of about one inch more or less as the circumstance
of the case may require which I call the water reservoir. The water contained
inside of reservoir may at all times be used to balance the lamp. The lamp may
be constructed as an ordinary table lamp with a wide base to form the foot of lamp
with the reservoir for oil ou the top. The distance between top of base and
bottom of oil reservoir may be of any length or both may be joined together.
From the under side of collar to which burner is secured I securely fix a brass
or other metal tube which I call the wick and water tube which I also securely
fix to the bottom of oil reservoir and continue the tube through any space there
may be between bottom of oil reservoir and top of water reservoir at base of
lamp to which I securely fix same at which point the tube is stopped.
Through the same tube directly above the bottom of oil reservoir I perforate
same with small boles through which at all times the oil in oil reservoir may
percolate to supply the wick to burner the oil in the said tube will always remain
at the same height as the oil in oil reservoir.
On filling lamp I first fill the reservoir at base through the collar to which
burner is screwed with water. The water runs down the wick and water tube
which fills the reservoir at base until the water is raised in the tube within about
one inch below the perforated holes in wick and water tube directly above bottom
of oil reservoir. The water only requires to be put in water reservoir once but
may be changed occasionally at discretion.
In filling the oil reservoir I fill same through a aperture with a screw plug at
top of oil reservoir. The oil on being poured in percolates through the holes at
bottom of reservoir in wick and water tube and is held in check from descending
to base of lamp by the water in tube the oil rising in the tube to the height of oil
in oil reserv..ir.
The lamp should it by any means be overturned the water by its greater
specific gravity immediately forces the oil in wick and water tube back from wick
to base of lamp and all further percolation from oil reservoir is sealed by the
water in the tube.
The lamp on being stood on its base again the oil will immediately fill its

page_text: position at top of tube the wick not being effected by its immersion in the water
from burning. Should the wick at any time touch the water below the level of
oil in wick and water tube, the illuminating power will not be effected by such
contact with the water.

An Improved Safety Lamp for Use with all kinds of Paraffin
or Kerosene Burners for Hand, Table, or other Moveable
Lamps.
I, ALFRED JOHN STONELY, of 28 Uridge Crescent, Tonbridge, in the County
of Kent, Joiner, 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 safety lamps, and consists of improvements in the
construction and design of such lamps whereby it is rendered impossible for paraffin
or other oil to come into contact with the flame should the lamp by accident be
overturned. The improved form of lamp is simple and efficient in action, and can
be manufactured at a low cost.
Many modifications of detail are possible in lamps constructed according to this
invention, the essential features being that the oil normally floats on the surface of
the water, and that should the lamp be overturned the water immediately comes
in contact with the base of the burner forces the oil immediately from the wick
tube through semi-circular or otherwise shaped openings at the base of one of the
four sides 6 which is uppermost, the oil from the wick tube being retained at the
highest point of base of lamp C, the water remaining at the base of burner
percolates through the wick and extinguishes the flame.
A simple form of lamp according to this invention is illustrated in the
accompanying drawings in which :-
Fig. 1 is an elevation of a lamp.
Fig. 2. is a vertical section through centre of same.
Fig. 3 is a plan of lamp with the burner removed.
A represents the body or container of the lamp, B the outer tube and C the
foot. Dis the burner which may be of any suitable construction. The gallery G
is made detachable to allow of cleaning out the air or draught space S underneath
when this becomes choked with dust and other deposits from the burner D. In
my improved lamp the bottom c of the foot C is made watertight, and a tube b is
soldered or otherwise attached to it, having also at this end one or more semi-
circular or otherwise shaped openings 63 cut in its sides to allow of the free passage
of water from the tube b into the foot C or vice-versa. The tube b passes up
through the centre of the outer tube B, and being made of suitable length to come
within a short distance of the base of the burner when screwed down, is attached to
the interior of the tube B,.the top of b being previously flanged out at 6 to fit the
bore of the pedestal tube B, and perforated with a number of small holes 63.
At or near the bottom of the container A, one or more small holes a are bored in
the tube B and a short tube a' is inserted in each which also passes through the
tube b, thus allowing free passage for the oil to the interior of the wick tube.
Oil is fed to the lamp in the ordinary manner through a tube a² which is secured
in the top of the container and fitted with a screw or other cap a³. The top of

page_text: the container A is recessed around the neck of the lamp N thus forming a drainer
in case the lamp is overfilled, thereby overcoming the objectionable oily exterior
surface of many lamps.
The lamp is operated thus:-Water is first poured down the tube 5 which flows
through and fills the foot of the lamp C and also flows up between the tubes B
and b in the space 6' until it nearly reaches the tube a'. Oil is then poured into
the container A through the tube a2 and flowing through the tube al floats on the
surface of the water in the interior of the tube b. When sufficient oil is put in
the container A, the burner D with the wick is then inserted and screwed or
otherwise attached and the lamp is ready for use. It will be seen that the oil is
prevented from entering the annular space between the two tubes B and b.
If at any time the lamp should be overturned by accident when lighted, the
water in the space between the tubes B and b will immediately be forced in jets
through the perforations 63 and falling on the wick forces the oil from the base of
the burner D through 6 and 2 to the base of the lamp, the water remaining at the
base of the burner percolates through the wick and extinguishes the flame,
thereby removing the danger of an ill fitting wick.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A lamp for burning paraffin and other oils in which the oil floats upon the
surface of water which is contained in the pedestal or in the body of the lamp,
substantially as shewn and described.
2. A lamp for burning paraffin and other oils in which the oil floats on the
surface of water contained in the inner tube of the lamp, and in which the oil is
prevented from entering an annular space between the inner and outer tubes,
substantially as shewn and described.
3. A lamp for hurning paraffin and other oils in which the parts are so arranged
that in case of the lamp being overturned, the water contained in an annular space
reaches the wick first, and immediately extinguishes the flame as described.
4. In a lamp for burning paraffin and other oils the combination of the
reservoir A, the tube B, the base C, the burner, and the perforations,
substantially as shewn and described.
5. In a lamp for burning paraffin and other oils, the combination of the
reservoir A, the outside tube B, the inner tube b having a perforated flange 6, the
base C and the burner D, substantially as shewn and described.
