An Improved Safety Oil Lamp.
I, WALTER WILLIAM HARE, of 13 Westbourne Park Crescent, County of
London, Wire Worker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to oil lamps, the object being to construct such lamps with
a weighted rounded bottom, so that if upset, or tilted beyond a given angle, they
shall re-assume an upright position, and be thus rendered safe. I provide lamps
made on my system with a screw-in tube, within and to which the burner can be
affixed, the tube serving also for enclosing the wick from the oil well, but into
which tube the oil has free entry for feeding the wick.
The upper part of the tube forms an air chamber to prevent the passage of oil to
the burner except by the wick, and I purpose arranging a drip receiver between
the burner and the head of the tube to receive any overflow, and to serve as
a shoulder for the fingers to catch under for carrying the lamp should there be no
handle for that purpose.
The system is specially applicable to domestic hand lamps but it can be adapted
for suspension, stand, bracket, and like supports.

I, WALTER WILLIAM HARE, of 13 Westbourne Park Crescent, County of
London, Wire Worker, 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 lamps, the object being to construct such lamps with
a weighted rounded bottom, so that if upset, or tilted beyond a given angle, they
shall re-assume an upright position, and be thus rendered safe. I provide lamps
made on my system with a screw-in tube, within and to which the burner can be
affixed, the tube serving also for enclosing the wick from the oil well, but into
which tube the oil has free entry for feeding the wick.
The upper part of the tube forms an air chamber to prevent the passage of oil to
the burner except by the wick, and I purpose arranging a drip receiver between the
burner and the head of the tube to receive any overflow.
The system is specially applicable to domestic hand lamps but it can be adapted
for suspension, stand, bracket, and like supports.
My invention is represented in the annexed drawings.
Figure 1 is a sectional elevation of a hand lamp, and Figure 2 a part sectional
elevation of the same.
A is the body of the lamp of round or semi-spherical formation with a flattish
bottom B with an internal weight C to enable the lamp to sit upright when laid
upon a support of any kind and to adjust itself to that position should it be

always causing the lamp to stand vertically.
The upper part D of the body A has an internally screw threaded neck E into
which a safety tube F is secured, slid, or brazed, said tube F reaching nearly to the
bottom of the body A. to form an air compression chamber G at its upper part by
the close fit of the burner neck H which screws into it and constitutes a sealed
joint, the neck E being also air tight by its close fit to the tube F.
The burner has a cone cup I within its ventilating barrel J, and this is provided
with holes K, K, for any overflow oil from the wick to settle in the chamber H to
be emptied therefrom when the lamp requires refilling, or a fine pin hole can be in
the bottom of the chamber for a gradual return of the overflow to the main body
of oil.
N is a handle by which the lamp can be carried, and the gallery P is shown with
a chimney Q. R is the extinguisher lever.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved safety oil lamp as shown on the annexed drawings, said lamp
having power to adjust itself to an upright position if upset or tilted beyond a given
angle, as described.
2. In an oil lamp, a drip receiver between the burner and the head of an inner
tube, as described and as shown.
