I, WILLIAM MOORE of 41 Melbourne Street in the City and County of Newcastle
upon Tyne, Boiler Smith, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to construct a Lamp for burning paraffin, or other
suitable oil, which will be free from the danger of fire or explosion if upset or when
extinguished by blowing out the flame.
The oil is contained in a reservoir separate from the wick which is enclosed in a tubo
in which it fits freely and which extends from the burner downwards to a small
chamber a little larger in diameter than the width of the wick. The oil is conveyed
to this chamber from the reservoir or reservoirs by a pipe or pipes and enters the
wick tube through a small hole or holes so as to saturate the wick without admitting
more oil than is necessary to supply the flame.
In the case of double wick Lamps two tubes will be used both terminating in the
chamber.
The oil containing reservoir may form an annular vessel around the stalk of the
Lamp or two or more reservoirs may be used an essential condition being that the oil
s considerably above the small chamber both for flowing to the wick as it is consumed
and with the important object that if the lamp is upset the supply is immediately cut
off by the oil flowing back into the reservoir thus all danger of fire or explosion is
prevented and the flame will be quickly extinguished. When the lamp is to be
extinguished there is no danger of explosion by blowing down upon the flame as the
pody of the oil is only connected with the small chamber and wick tube by the small
holes.

I, William Moore, of 41 Melbourne Street, in the City and County of Newcastle
upon Tyne, Boiler Smith, do hereby declare the nature of said 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 my invention is to construct a lamp for burning paraffin, or other
suitable oil, which will be free from the danger of fire or explosion if upset or when
extinguished by blowing out the flame.
The oil is contained-in-a reservoir separate from the wick which is enclosed in a
tube in which it fits freely and which extends from the burner downwards to a small
chamber, a little larger in diameter than the width of the wick. The oil is conveyed
to this chamber from the reservoir or reservoirs by a pipe or pipes and enters the wick
tube through a small hole or holes so as to saturate the wick without admitting more
oil than is necessary to supply the flame...
In the case of double wick lamps two tubes will be used both terminating in the
chamber.
The oil containing reservoir may form an annular vessel around the stalk of the
lamp or two or more reservoirs may be used an essential condition being that the oil
is considerably above the small chamber both for flowing to the wick as it is consumed
and with the important object that if the lamp is upset the supply is immediately cut
off by the oil flowing back into the reservoir thus all danger of fire or explosion is
prevented and the flame will be quickly extinguished. When the lamp is to be
extinguished there is no danger of explosion by blowing down upon the flame as
the body of the oil is only connected with the small chamber and wick tube by
the small holes.
I may in some cases dispense with the chamber to receive the oil from the reservoir
or reservoirs, thus simplifying the construction of the lamp, as I have. found that the
lamp may be made equally safe by conveying the oil direct to the wick tube and
admitting it thereto through a small hole or holes in the way illustrated on the
drawings which are attached to this Specification.
DESCRIPTION OF DRAWINGS.
On the accompanying sheet of drawings I illustrate my invention as applied to
lamps in 3 different forms.
Fig. 1 is a sectional elevation and Fig. 2 a sectional plan on X-X (Fig. 1) of a
lamp constructed as described in my Provisional Specification with a small chamber C
into which the oil is conveyed from the reservoirs A A' by the tubes B B¹. D is the
wick tube terminating at top in the burner E and at bottom in the chamber C from
which the oil flows to the wick through a small hole or holes which only allow a
sufficient quantity to pass to supply the wick.

page_text: Fig. 3 is a sectional elevation and Fig. 4 a sectional plan on X-X (Fig. 3) of a
lamp in which the oil chamber is dispensed with, as previously named and as I have,
in practice, found that it may be. In this case the oil flows from the reservoirs A A¹
down the tubes B. B which join the wick tube D at its lower end where it is
perforated with one or more small holes through which the oil flows to supply the wick
in quantity sufficient to keep the lamp burning.
Fig. 5 shews a sectional elevation of a lamp in which the reservoir A is an annular
vessel, surrounding the wick tube D, from which the oil flows down the tubes B. B¹
and enters the wick tube through a small hole or holes as in Fig. 3 or it may be
conveyed into a chamber as in Fig. 1.
It will be evident that many modified forms of carrying out my invention may be
adopted without departing from its essential features viz. that the oil shall be supplied
to the wick in such a manner and in such quantity that if the lamp is upset or even
partially upset the oil instantly flows back into the reservoir cutting off the supply to
the wick which extinguishes the flame whilst there is no danger of explosion because
the wick is not in communication with the body of oil in the lamp.
If the invention is applied to a double wick lamp the construction only requires
modifications which will be perfectly evident to meet the case of two wicks instead
of one.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
The construction of lamps, for burning paraffin or other oils, in which the oil is
contained in a reservoir, or reservoirs, and flows to the wick which is enclosed in a
tube, only in sufficient quantity to supply the light; said reservoir being so situated
that if the lamp is partially or entirely upset, the oil flows back into them, instantly
cutting off the supply to the wick and extinguishing the flame; the isolation of the
wick from the oil also preventing explosion by blowing down upon the flame to
extinguish it.
