PROVISIONAL SPECIFICATION.
An Improved Apparatus for Self-extinguishing Paraffin and other
Oil Lamps.
JOHN BROWN 504 Lord Street Liverpool, Accountant do hereby declare the nature
of this invention to be as follows:-
This invention serves the double purpose of extinguishing the light upon turning
down the wick; and, in the event of the lamp being overturned the extinguisher
falls over the lighted wick and at once puts out the light. It also improves the
light.
The apparatus or extinguisher is constructed in the following manner :-Two
metallic hoods (shaped somewhat like the two halves of a bell being much broader at
the base than at the top, or may be made somewhat in the form of a wedge) made to
fit loosely over wick tube, fastened together by means of two pins secured on the sides
of inner hood and allowed to play loosely in corresponding holes in outer hood, the
jaws of the hoods which meet closely are made with straight edges, or may be made
with toothed edges, are bent at an outer angle from the sides and fall when closed
just over top of wick tube.
The said hoods being wider at the base and resting on their extreme edges on the
boss at the base of wick tube act as levers and close by means of their own weight.
The two pins are placed about three fifths down from the top of the hood allowing
the hoods to close at a moderate angle in case the lamp upsets, in such case the
extinguisher falls over the lighted wick, closes and puts out the light.
The said hoods are perforated with a row of holes or slots near the base on either
side, also with another row of holes near the angle at the top of the straight edged
ones, (but in the case of the tooth edged ones the holes at the top are not required)
for the purpose of supplying air to flame to support combustion.
When the wick is turned up it forces open the hoods but when it is turned down
the hoods close over the wick instantaneously putting out the light.

COMPLETE SPECIFICATION.
An Improved Apparatus for Self-extinguishing Paraffin and other
Oil Lamps.
I, JOHN BROWN of 50 Lord Street Liverpool Accountant, 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 serves the double purpose of extinguishing the light upon turning
down the wick; and in the event of the lamp being overturned the extinguisher
falls over the lighted wick and at once puts out the light. It also improves tho
light.
The apparatus or extinguisher is constructed in the following manner: Two
metallic hoods (shaped somewhat like the two halves of a bell being much broader
at the base than at the top, or may be made somewhat in the form of a wedge)
made to fit loosely over wick tube, fastened together by means of two pins secured
on the sides of inner hood and allowed to play loosely in corresponding holes in
outer hood, the jaws of the hoods which meet closely are made with straight edges
(or may be made with toothed edges) are bent at an outer angle from the sides
and fall when closed just over top of wick tube. The said hoods, being wider at

page_text: the base, and resting on their extreme edges on the boss, at the base of wick tube
act as levers and close by means of their own weight.
The two pins are placed about three fifths down from the top of the hood allowing
the hoods to close at a moderate angle in case the lamp upsets, in such case the
extinguisher falls over the lighted wick, closes and puts out the light. The said hoods
are perforated with a row of holes or slots near the base on either side, also with
another row of holes near the angle at the top of the straight edged ones, (but in the
case of the tooth edged ones the holes at the top are not required) for the purpose
of supplying air to flame to support combustion.
When the wick is turned up it forces open the hoods but when it is turned down
the hoods close over the wick instantaneously putting out the light.
By means of extinguisher under my invention:
The light is improved (without extra consumption of oil).
The light is self-extinguished by turning down the wick.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a view part in section of a lamp burner showing my improved extinguisher
the wick being raised.
Fig. 2 is an elevation of a burner with the wick lowered and the extinguisher in
operation.
Fig. 3 is a perspective view of the extinguisher, and
Fig. 4 is a view of a burner showing the action of the extinguisher when a lamp is
upset.
a is the burner, b wick tube, c wick, d dome, e e¹ metallic hoods hinged at ƒ so as
to form an extinguisher, g g¹ rows of apertures to allow of access of air to the wick.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
First. Extinguishers for lamps consisting of two hoods pivotted together and fitting
freely over the wick tube substantially as set forth.
Second. Extinguishers for lamps consisting of two hoods pivotted together fitting
freely over the wick tube and provided with apertures substantially as and for the
purposes set forth.
