PROVISIONAL SPECIFICATION.
Improvements in or Connected with Extinguishers for Wick Oil
Lamps.
1, WILLIAM TAYLOB of City Buildings Old Hall Street Liverpool Commission
Agent do hereby declare the nature of my said invention to be as follows
--
The object of my invention is to provide a means by which the flame of petroleum
or paraffin oil lamps having round or annular wicks shall be extinguished auto-
matically in case they should become upset.
According to this invention I provide a body within the wick tube which is capable
of moving up and down therein. The body may be of considerable weight so as to
cause it to move with certainty when the lamp becomes upset. The body is so arranged
that when it comes into action it will fill the aperture through which the air for sup-
porting combustion of the flame internally passes: the said air supply would be
thus stopped. The body may be arranged to slide on a stem or guide or within
same; and its travel would be limited by a stop provided either on its guides or the
wick tube, or by any other suitable means.
In cases in which the extinguisher is or is to be applied to existing forms of
lamps a suitable socket, pedestal or other equivalent or suitable device may be used to
support or hold the guide in position if such guide be necessary.
In connection with the internal extinguishing body I may use a sleeve on the
exterior of the wick tube, such sleeve being adapted to slide up and down on the tube
in such a manner that the air will be excluded from the wick and flame when the
lamp is upset and the sleeve has slid over the end of the wick tube. The travel of
this sleeve would also be limited.

COMPLETE SPECIFICATION.
Improvements in or Connected with Extinguishers for Wick Oil
Lamps.
I, WILLIAM TAYLOR, of the City Buildings, Old Hall Street, Liverpool, in the
County of Lancaster, Commission Agent, do hereby declare the nature of my 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 provide a means by which the flame of petroleum
or paraffin oil lamps having round or annular wicks shall be extinguished automatically
in case they should become upset.
According to this invention I provide a body within the wick tube, which is capable
of moving up and down therein. The body may be of considerable weight so as to
cause it to move with certainty when the lamp becomes upset. The body is so arranged
that when it comes into action it will fill the aperture through which the air for sup-
porting combustion of the flame internally passes, and the said air supply would be
stopped. The body may be arranged to slide on a stem or guide or within the wick
tube, and its travel would be limited by a stop provided either on its guide or the
wick tube, or by any other suitable means.
In cases in which the extinguisher is or is to be applied to existing forms of lamps,
a suitable socket, pedestal, or other equivalent, or suitable device, may be used to
support or hold the guide in position, if such guide be necessary.

page_text: In connection with this internal extinguishing body I may use a sleeve on the
exterior of the wick tubes, such sleeve-being adapted to slide up and down on the
tube in such a manner that the air will be excluded from the wick and flame when
the lamp is upset and the sleeve has slid over the end of the wick tube. The travel
of this sleeve would also be limited.
The nature of my Invention will be more fully understood on reference to the
accompanying sheet of Drawings. (making a part of this Specification) which are
marked with letters and figures of reference corresponding with those used in the
following explanation, like letters and figures being used to denote like parts through-
out the Drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation and Figure 2 a plan of an extinguisher, according to my
Invention, to be applied to oil lamps having round or annular burners.
Figure 3 is a front sectional elevation of a round or annular burner of an oil lamp,
provided with an extinguisher according to my Invention.
Figure 4 is a side view, and
Figure 5 is a sectional pian of the burner and extinguisher.
Figure 6 shows the burner in a turned-over position and illustrates the action of the
extinguisher.
a is the wick tube of the burner which is of a well known kind; within this wick
tube a,
I insert the device shown at Figures 1 and 2, which consists of a body b,
which may be of the form shown in the drawings or other suitable form.
This
body is carried by and slides on a vertical rod c held to the lower part of the wick
tube a by the plate d, the body b, rod c, and plate d being inserted into the wick
tube a through the triangular air opening e. The body b is capable of moving up
and down in the tube a and is of considerable weight so as to cause it to move with
certainty when the lamp becomes upset. The body b is of size to fill the aperture at
top of the tube a, through which the air for supporting the combustion of the flame
is supplied, and by stopping the supply of air the flame is extinguished. The action
being that when the lamp is upset the body b automatically slides down the tube a
and stops the mouth of the tube as shown in Figure 6 the travel being limited by the
stop on the rod c. In cases where the rod c is not used, the body b must be
of form and size to guide itself and close the mouth of the tube a when the lamp is
upset.
*In connection with the body b, and as an additional means for extinguishing the
flame, I may use a sleeve on the exterior of the wick tube a, the sleeve being weighted
and made to slide on the tube a, and over the end thereof, so that when the lamp
turned over or upset, the air is shut off from both the inside and outside of the wick,
a stop being provided on or in connection with the sleeve to prevent it falling off the
end of the tube a.
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 :-
1
1. In extinguishers for oil lamps in which round or annular wicks are used, the
.employment of a body within the wick tube, capable of moving automatically up and
down therein; for the purposes set.forth.
2. In extinguishers for oil lamps in which round or annular wicks are used, a
body within the wick tube, capable of moving automatically up and down therein
and guided in its movements.
3. In extinguishers for oil lamps in which round or annular wicks are used, the
construction of the extinguisher body herein specified, or the wick tube, or the body
and wick tube in combination, in such a manner that said body is prevented.from
falling out of the mouth of the wick tabe when in operation; substantially as herein
above specified.

page_text: 4. As an article for use as an extinguisher in oil lamps in which round or annular
wicks are used, a body constructed and adapted to fit and move within the wick tube
of such lamp; as or substantially as herein described.
5. As an article for use as an extinguisher in oil lamps in which round or annular
wicks are used, a body and a stem or slide adapted to guide said body when moved
up and down on or in connection with same, said body and stem or slide being
constructed and adapted to fit and operate within the wick tube of such lamps; as or
substantially as herein described.
6. In extinguishers for oil lamps in which round or annular wicks are used, the
combination of a body, adapted to move up and down within the wick tube of the
lamp, and a sleeve or aunular body adapted to move up and down on the outside of
said wick tube; substantially as and for the purposes set forth.
7. The construction and arrangement of oil lamp extinguisher set forth with
reference to the drawings.
8. The combination of extinguisher and wick tube of the type illustrated, as set
forth with reference to the drawings.
