WILLIAM NOTLEY 27 Nutcroft Road Naylor Road Peckham London S.E.
Commercial Traveller I do hereby declare the nature of this invention to be as
follows:-
:-
1st. To the Screw or bottom end of any Petroleum burner to attach by Solder or
otherwise a metal Tube padded inside with a porous stone but having sufficient space
for a cotton wick to pass down-The tube being also plugged at the bottom with the
same porous stone-Now when the burner with this attached tube is fixed in the
usual manner in the oil vessel with the oil as usually therein contained thro' the above
porous stone the oil will permeate in sufficient quantities to be sucked up by the wick
which has been placed thro' the burner in the usual way & passed into the Tube &
by the usual Capillary attraction perfect Combustion is produced-the same exactly as
if the oil had not passed thro' the porous tube-Nevertheless the safety of the lamp or
Reservoir is secure from explosion as it will be impossible in extinguishing the Lamp
either in blowing down the chimney or in any other of the usual methods of
extinguishing: all of which more or less are calculated to drive the igniting gas into
the Reservoir of the Lamp & as it will be impossible for the gas to pass
down any
other way except thro' the tube attached to the bottom of the burner, & which Tube is
impervious to any gas for altho' thro' the porous stone the oil can permeate the gas
cannot The same thing applies to any other of the numerous causes by which
explosions occur.
Also it is claimed, no matter how small or narrow a wick may be used either by
accident or design, no explosion can occur as soon would be the case in the ordinary
burners, because altho' thro' the vacuum not filled up by a too narrow wick in the
wick case or tube of the burner-the gas would readily pass down & cause an
explosion-whereas all burners with the tube attached with the porous stone as described
above-no matter how narrow the cotton wick was or how much vacuum in the wick
case or how much igniting gas passed down-all causes of explosion are at once
removed by reason of the inability of the igniting gas being unable to pervade the
porous stone in the tube attachment.
2nd. To doubly secure the safety of any Lamp burning hydro-carbon oil from

page_text: explosion either thro' careless extinguishing or by reason of the Lamp being upset or
partly upset, an automatic extinguisher is attached to the Top of the wick case imme-
diately beneath the Dome of the burner, which automatic action simply consists of two
discs or flaps closing automatically by Hinges over the wick case extinguishing the
light instantaneously, but which action instead of being worked by a Lever &
spring in the usual way-I place below the flaps or dises to slide over the wick case-
a perfectly smooth heavy metal Ring, which upon the slightest deflection of the
Lamp & of its own accord & automatically gravitates upwards & falling against the
flaps immediately closes them together which instantly & automatically extinguishes
the Lamp.

I, WILLIAM NOTLEY 27 Nutcroft Road Naylor Road Peckham London S.E.
Commercial Traveller, 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 a burner for lamps burning mineral oils the object of
which is to obviate all danger of ignition of the oil or the vapours in the reservoir
from the burner on the upsetting of the Lamp, or in the endeavour to extinguish the
light by blowing down the Chimney, or from other well known causes; and further,
to prevent the ignition of any oil flowing from the wick case on the upsetting of
the lamp.
The burner protects the oil in the reservoir from ignition therefrom by enclosing
the wick in a porous chamber formed of pumice stone, porous stone, or similar
substance encased at its sides in a metal tube, or at sides and at the base with wire
gauze say 29 meshes to the inch through which flame cannot pass to the oil or the
vapours in the reservoir, but which will permit this oil to permeate through it to feed
the wick; and the ignition of any oil contained in the wick case at the moment of the
overturning of the lamp is prevented by an automatic extinguisher, forming part of
the burner, which extinguishes the flame before the lamp can have passed so far from
the vertical as to permit this oil to reach the flame.
A Burner embodying my invention is shown upon the accompanying sheet of
Drawing upon which
Fig. 1 is a cross section through the burner and wick case.
Fig. 2. being a side view of saine also shewn in section.
Fig. 3 represents a similar view to the above, but with burner shown at an
inclination, the extinguisher being closed by the action of the sliding weight.
Fig. 4 is a plan of Fig. 2.
A indicates the burner.-B Metal tube.-b the wick case.-C porous substance.—
D space for wick.-E Cotton wick.-F bottom of tube B-G the oil-vessel or
reservoir. H The oil.-I The dome of the burner.-K flaps or discs.-L hinges for
same. M metal ring.-m slides for metal ring.
To the screw or bottom end of my petroleum burner (A) I attach by solder, or
otherwise, the metal tube (B) padded inside with a porous stone (C) or any similar
substance, but leaving sufficient space (D) for a cotton wick (E) to pass down. The
tube (B) being also plugged at the bottom (F) with similar material. Now when the
burner (A) with this attached tube (B) is fixed in the usual manner in the Oil
vessel (G) the oil (H) being contained therein as usual, the oil (H) will permeate in
sufficient quantity through the porous substance (C) to be sucked up by the
wick (E) which has been placed through the burner (A) in the usual way and
passed into the wick case. (b) where it takes up oil by the usual capillary
attraction exactly as if the oil had not passed through the porous substances;

page_text: nevertheless the lamp or reservoir (G) is now secure from explosion, as in
extinguishing the Lamp, either in blowing down the Chimney, or in any other
of the usual methods of extinguishing, (all of which are more or less calculated to
drive the flame into the reservoir (G) of the lamp) it will be impossible for the
flame to pass down any other way except through the tube (B) attached to the 5
bottom of the burner (A) which tube (B) is impervious to any flame for although
the oil can permeate through the porous stone (C) the flame cannot. This also

applies to any other of the numerous causes by which explosions occur.
matter how small or narrow a wick may be used, (either by accident or design)
1
no explosion of the oil in the reservoir can occur with my burner, as would soon
be the case in the ordinary burners, because, although by reason of the vacuum
not being filled up by a too narrow wick in the wick case (b) or tube (B) of the
burner the flame would readily pass down and cause an explosion, my porous
lining as described above will, no matter how narrow the wick or how much
vacuum in the wick case, or how much vapour in the reservoir, prevent the 1
explosion of the vapours in the reservoir, by reason of the inability of the flame
to pass through this porous material.
The tube (B) may be perforated or not and he closed at bottom with wire
gauze and porous lining or with porous substance only, as may be found most
desirable.
To doubly secure the safety of any lamp burning hydro-carbon oil from
explosion, either through careless extinguishing, or by reason of the lamp being
upset or partly upset, I attach an automatic Extinguisher to the top of the wick
case (b) immediately beneath the dome (I) of the burner (A), this automatic
extinguisher consisting of two discs or flaps (K K) pivoted or hinged over the
wick case (b) which upon closing extinguish the light instantaneously, but which
instead of being worked by a lever and spring in the usual way to pass over the
wick case (b) are operated by a smooth heavy metal ring or plate (M) or its
equivalent, which upon the slightest deflection of the lamp, and of its own accord
assisted by the slides m automatically gravitates upwards and falling against the
flaps immediately closes them together thus instantly and automatically extinguishing
the lamp.
I have shown the wick (E) see Fig. 2 and 3 not inclosed on all sides by porous
material but it may be surrounded thereby if found preferable.
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 :—
1°. A Burner for Lamps burning mineral oils having a wick holder fed with oil
from the reservoir only through a porous substance which at the same time prevents
the passage of flame to the reservoir substantially as described.
20. In a Burner for oil Lamps, an Extinguisher consisting of the two pivoting
discs or flaps (K K), or their equivalent in combination with the ring or plate (M),
or its equivalent, the whole arranged to operate substantially as described.
3°. The burner for oil Lamps hereinbefore described and illustrated in the
accompanying sheet of Drawings.
