PROVISIONAL SPECIFICATION.
An Improved Non-explosible Reservoir for Use with Paraffin or
Kerosene Lamps and Stoves.
We ALFRED JOHN STONELY of 28 Uridge Crescent, Tonbridge, Kent, and
ALFRED ACHILLES STONELY of 5 Audley Road, Richmond, Surrey, both
Joiners, do hereby declare the nature of this invention to be as follows:-
This invention relates to oil reservoirs used with paraffin or kerosene lamps or
stoves and is adapted for use with any cooking or heating stove, or any kind of
lamp used for lighting purposes, and for any size or description of wick, round,
central draught or any flat wick of from one eight of an inch upwards in use or used
for lighting or cooking purposes.
The reservoir may consist of a metal easing of either tin, brass or other suitable
metal, and be of any shape, either round, square or oblong, or of any depth that the
circumstances of the case may require, with a division four sevenths of the height
from the bottom.
Between this division and the bottom of the reservoir a chamber is thus formed
which I call the oil chamber.
The remaining three-sevenths that is from the top of the division to the top of
the reservoir a second chamber is formed which I call the water chamber.
A wick chamber is then provided which runs from and is fastened to the bottom
of the reservoir.
This chamber passes through the division to the under side of the screw collar
for the burner, thus excluding oil or water from entering it. In this wick chamber
immediately below the division in the reservoir I form several small holes through
which the oil percolates from the oil chamber, forced up by the water from the
upper chamber which as the oil is burned gradually falls into the lower chamber.
The wick chamber holds sufficient oil to allow of the lamp hurning about half an
hour after the oil in the oil chamber is consumed. The water chamber only
requires to be filled after first filling at intervals of about one month, and this only
for the purpose of replacing with clean water.
When the lower reservoir is being re-filled with oil, the oil forces the water back
in the upper chamber.
A feed pipe of the usual kind passes down through the top of the reservoir into
the oil chamber and a similar feed pipe is provided to communicate with the water
chamber. This same pipe acts as a return pipe for the water to water chamber on
refilling the reservoir for oil. These feed pipes are closed with a screw cap of the
usual kind.
The shape and position of the water supply pipe can be varied as the shape of the
lamp may require.
Owing to the position of the water in the top of the reservoir being between the
oil in the lower chamber and the flame, the burner is always kept cool.
There being no vacuum in the oil reservoir no gas can generate, consequently
should the lamp overturn it is impossible for an explosion to take place.

An Improved Non-explosible Reservoir for Use with Paraffin or
Kerosene Lamps and Stoves.
We, ALFRED JOHN STONELY of 28 Uridge Crescent, Tonbridge, Kent, and
ALFRED ACHILLES STONELY of 5 Audley Road, Richmond, Surrey, both
Joiners, 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 oil reservoirs used with paraffin or kerosene lamps or
stoves, and is adapted for use with any cooking or heating stove, or any kind of
lamp used for lighting purposes, and for any size or description of wick, round
central draught or any flat wick of from one eight of an inch upwards in use or
used for lighting or cooking purposes.
The reservoir may consist of a metal casing of either tin, brass or other suitable
metal, and be of any shape, either round, square or oblong, or of any depth that the
circumstances of the case may require, with a horizontal division about four sevenths
of the height from the bottom.
Between this division and the bottom of the reservoir a chamber is thus formed
which I call the oil chamber.
The remaining three-sevenths that is from the top of the division to the top of
the reservoir, a second chamber is formed, which I call the water chamber.
A wick chamber is then provided which runs from and is fastened to the bottom
of the reservoir.
This wick chamber passes upwards through the division to the under side of the
screw collar for the burner, thus excluding oil or water from entering it. In this
wick chamber immediately below the division in the reservoir, that is, near the top
of the oil chamber, I form several small holes through which the oil percolates from
the oil chamber, forced up by the water from the upper chamber, which as the oil
is burned, gradually falls into the lower chamber.
The wick chamber holds sufficient oil, to allow of the lamp burning about half
au hour after the oil in the oil chamber is consumed. The water chamber only
requires to be filled after first filling at intervals of about one month, and this only
for the purpose of replacing with clean water.
When the lower reservoir is being refilled with oil, the oil forces the water back
into the upper chamber.
A feed pipe of the usual kind passes down through the top of the reservoir into
the oil chamber and a similar feed pipe is provided to communicate with the water
chamber. This same pipe can be prolonged so as to act as a return pipe for the
water to the water chamber on refilling the reservoir with oil. These feed pipes
are closed with a screw cap of the usual kind.
The shape and position of the water supply pipe can be varied as the shape of
the lamp may require.
Owing to the position of the water in the top of the reservoir being between the
oil in the lower chamber and the flame, the burner is always kept cool.
There being uo vacuum in the oil reservoir no gas can generate, consequently
should the lamp overturn, it is impossible for an explosion to take place, and as only
a small amount of oil can be spilled through the holes in the wick tube there is no
danger of causing a conflagration.
I will now describe the invention with reference to the accompanying drawings
in which :-

draught.

ii are feet to uphold the burner to allow the central draught to act.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a reservoir for burning mineral oils or like purposes, consisting of a
container or hollow vessel, distinguished by a central vertical wick tube, around
which there may be another vertical tube, forming an annular space, around the
outside vertical tube is a horizontal partition forming two chambers, namely, a
lower chamber for oil, and an upper chamber for water, the oil chamber com-
municating by small holes, near its top, with the annular space around wick tube,
and that space similarly communicating with the wick tube.
The water chamber communicating by means of a vertical tube with the bottom
of the oil chamber, and each chamber having its own feed-pipe for feeding purposes,
as herein described and set forth.
2. A safety burner, consisting of the container mentioned in Claim 1 in com-
bination with an ordinary burner for mineral and other oils, in which by means of a
horizontal partition, a water chamber is created above the oil chamber, keeping the
oil cool, and so communicating therewith, that no vacuum can be formed above the
oil, because as the oil is consumed, the water entering the oil chamber from below,
by means of a tube provided for the purpose, forces the oil upwards against the
horizontal partition which covers the oil chamber, said oil entering the wick tube
by small holes, sufficient for lighting purposes, near the top of the said oil chamber,
so that in case of the lamp on which the container is fixed being overturned, no oil
can escape, no explosion can occur, and no danger of fire will ensue, as herein
described and set forth.
