I, HENRY NICOLL of 45 Warwick St. Golden Sq. London Outfitter do hereby
declare the nature of my invention for A SAFETY AUTOMATIC EXTINGUISHER FOR
LAMPS BURNING MINERAL OILS to be as follows:-
I place in the lamp below the burners a lever, having at the projecting end a cup
or socket to receive a round or other shaped weight. The lever works upon a pivot
and raises and lowers the extinguisher in such a way that when the weight is in
the cup or socket the Extinguisher is down but in the event of the lamp being
upset or tilted beyond a certain angle the weight falls out of the cup or socket and
a spring causes the extinguisher to rise and instantly puts out the lamp.
The Extinguisher I make in two ways suitable to different burners. Fig.
shows the Automatic Extinguisher applied to an ordinary duplex burner (one
burner being removed to show the working parts) A is the burner. B the sliding
extinguisher. O is the lever having at the projecting end the loose weight D. at
the other end of the lever is the spring E which raises the extinguisher and puts
out the lamp as soon as the weight falls out of the cup or socket. The pivot or
fulcrum for the lever to work on is shown at F. The spring to raise the
extinguisher is either a coiled spring as shown at E or a steel spring pushing
upwards and placed between the pivot and the weight.
Fig. 2. shows one form of Extinguisher, being a sliding tube A with one side
higher than the other, to the lower side I hinge a piece of metal B with a projecting
arm at one side, this projecting arm strikes against a peg C in the burner when
the sliding tube rises and causes the piece of metal to shut down and extinguish
the flame.
Fig. 3 is another form of Extinguisher. A piece of metal forming a hood A is
pivotted into the sides of the burner B when the sliding tube C rises a projecting
piece of metal D pushes up the hood A and together they form the extinguisher.
Both the extinguishers are worked in the same way by the lever acted on by the
spring and loose weight as shown in Fig. 1. and one or other can be used with
round, flat or oval burners, single or duplex.

I HENRY NICOLL of 45 Warwick Street Golden Square London W Outfitter do
hereby declare the nature of my invention for A SAFETY AUTOMATIC EXTINGUISHER
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
$
I place in the Lamp below the burner or burners a lever having at the projecting
end a cup or socket to receive a round or other shaped metal weight. This lever
is hinged to one side of the lamp frame and has beneath it a steel spring. The
lever is connected with the Extinguisher in such a way that when the weight is in
the cup or socket the Extinguisher is down and out of action, but in the event of
the lamp being upset or tilted beyond a certain angle (this angle can be regulated
by the depth of the socket) the weight falls out of the cup or socket and the
spring causes the lever and extinguisher to rise up instantly putting out the Lamp.
The Extinguisher I make in two ways suitable to different burners, one being a
hood pivotted into the burner tube and brought into action by a projection on
a sliding tube which with the hood forms the extinguisher. The other is a sliding
tube with one side higher than the other, to the lower side I hinge a piece of metal
with a projecting arm at the side, this projecting arm strikes against a peg in the
burner when the sliding tube rises and causes the piece of metal to shut down and
extinguish the flame. Both extinguishers are put into action in the same way by
the lever acted on by the spring when the weight has fallen out of the socket.
Fig. 1 shows the Automatic Extinguisher applied to an ordinary single burner
lamp A is the burner, B the sliding extinguisher, C. is the lever having at its
extremity the cup or socket to receive the weight D. E is the spring which forces
up the lever and puts the Extinguisher into action when the weight D is out of the
socket.

Fig. 2 shows one form of extinguisher being a sliding tube A with one side
higher than the other. To the lower side I hinge a piece of metal B with a
projecting arm at one or both sides, this projecting arm strikes a peg C (or pegs,
one on each side) at the top of the burner tube when the sliding tube rises causing
the piece of metal B to shut down and extinguish the flame.
Fig. 3 is another form of extinguisher, a metal hood A. is pivotted into the sides
of the burner B. When the sliding tube Crises a projection on it Depushes up the
hood A and together they form the extinguisher.
Both forms of extinguisher are worked in the same way by the lever acted on
by a spring and loose weight and one or other can be used with any shaped burner
either single or duplex.

page_text: 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
1st The forms of Extinguishers as shown in Figures 2 and 3 are novel.
2nd The automatic action of the loose weight socket and spring as shown in
Fig. 1 in working the lever and extinguisher is novel.,
