Burning Petroleum and the like.
I FRANCIS JOSEPH BATEMAN ALLEN of 44 Upper East Smithfield in the City. of
London, Merchant and Manufacturer, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN AUTOMATIC EXTINGUISHING DEVICES FOR LAMPS
BURNING PETROLEUM AND THE LIKE," to be as follows:-
-
This invention relates to that class of devices which serve to extinguish lamps
burning petroleum and the like, when such lamps are upset.
In fitting a lamp with this invention I place on the wick-tube an extinguisher so
arranged that when the same is operated it covers the top of the wick and extinguishes
the flame. This extinguisher is operated by a lever or rod which passes through the
body of the lamp into the foot of the same. In the foot of the lamp there are two
levers so connected with the rod hereinbefore mentioned that when the two levers
are pressed or pushed upwards against the foot of the lamp, the rod (and consequently
the extinguisher) are in that position in which it leaves the flame uncovered.
the levers in the foot of the lamp are set free they actuate the rod which, operating
the extinguisher, extinguishes the flame.
When
Springs are provided in such a manner that the extinguisher is kept clear of the
flame when the lamp is placed upon a table or other horizontal surface, the weight of
the lamp counteracting the tension of the springs. When the lamp is overturned
the pressure is removed, the extinguishing device at once becomes operative and
extinguishes the flame.
There is also provided an attachment on the outside of the lamp so connected with
the extinguishing device, that when the lamp is intentionally raised this attachment
may keep the extinguisher clear of the flame.
Dated this 15th day of March 1888.

Improvements in Automatic Extinguishing Devices for Lamps
Burning Petroleum and the like.
I FRANCIS JOSEPH BATEMAN ALLEN of 44 Upper East Smithfield in the City of
London, Merchant and Manufacturer do hereby declare the nature of my said
invention for "IMPROVEMENTS IN AUTOMATIC EXTINGUISHING DEVICES FOR LAMPS
BURNING PETROLEUM AND THE LIKE," 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 that class of devices which serve to extinguish lamps
burning petroleum and the like when such lamps are upset.
In fitting a lamp with this invention I place on the wick-tube an extinguisher so
arranged that when the same is operated it covers the top of the wick and
extinguishes the flame. This extinguisher is operated by a lever or rod which passes
through the body of the lamp into the foot of the same. In the foot of the lamp
there are two lovers so connected with the rod hereinbefore mentioned that, when the
levers are pressed or pushed upwards against the foot of the lamp the rod (and
consequently the extinguisher) is in that position in which it leaves the flame
uncovered. When the levers in the foot of the lamp are set free they actuate the
rod which operating the extinguisher extinguishes the flame.
Springs are provided in such a manner that the extinguisher is kept clear of tho
flame when the lamp is placed upon a table or other horizontal surface, the weight
of the lamp, counteracting the tonsions of the springs. When the lamp is over-turned
the pressure is removed, the extinguishing device at once becomes operative and
extinguishes the flame.
There is also an attachment on the outside of the lamp so connected with the
extinguishing device that when the lamp is intentionally raised this attachment may
keep the extinguisher clear of the flame.
The accompanying drawings show in fig. 1 a sectional elevation of a lamp with a
round-wick in fig. 2 a similar view of a lamp with a flat-wick in either form with my
invention applied thereto.
A is the body of the lamp B the wick tube C the foot of the lamp.
In the lamp fig. 1 the flame spreader c acts as the extinguisher when pulled down
upon the wick by the rod D). At its lower end the rod D is fitted with the links or
bars E connecting it with the levers F F pivotted in G and acted upon by
springs H H. A ring I slides on the outside of the foot of the lamp and is, by a
pin I connected with rod D.
When the lamp is placed on a horizontal surface, or when it is carried by the
ring the parts are in the position shown in full lines but when the lamp is upset
the springs H press upon the levers F and cause these to pull rod D downward
until the flame-spreader C covers the flame and extinguishes it.

page_text: The action for flat flame burners (fig. 2) is analogous. The rod D is in this case
connected with the extinguisher J of usual construction. The rod and extinguisher
are shown united by a screw K but any suitable catch, spring, or other connection
may be employed.
In figure 2 a modified arrangement of connecting the ring I and rod D is shown
but this is equally applicable to round wick lamps. This connection consists in two
arms 12 12 united with the ring I and brought together at their lower end at 1³ the
rod is attached, by a screw or otherwise to the part 13. The action will be readily
understood from what has been stated with reference to fig. 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that I claim :-
1.) In a lamp having a round wick the movable flame spreader c acting as an
extinguisher when operated by the rod D, the latter being actuated by the levers F F
connected therewith by links or bars E and fitted with springs H H substantially as
shown and described.
2.) In a flat wick lamp the combination consisting of the extinguisher Ja
screw Kor its equivalent, a rod D operated by the levers FF with which it is
connected in the manner shown in fig. 2 of the drawings and the ring 1 and
arms I 12 all as hereinabove specified.
