PROVISIONAL SPECIFICATION.
An Extinguisher for Paraffin Oil Lamps with Central Air Passage
and Flame Spreader.
EDWIN COMPTON Artist 46 Chapel Road Worthing Sussex do hereby declare
the nature of this invention to be as follows:-
This invention relates to extinguishers for paraffin oil lamps of the Carolus
and similar types having circular wicks and central air passage with flame
spreader.
The above invention consists of a circular disc made of brass or other convenient
material, as shown at A Figs. 1. 2. 3. of accompanying drawings which disc when
the lamp is in use is close under the flame spreader B. as shown in Fig. 2. When it
is desired to extinguish: the lamp this disc is drawn down on to the top of the wick
tube as shown in Fig. 3.
For application to existing lamps the invention would be constructed as follows.
The disc E. Fig. 4. is made in halves with projections on the under sides for
fastening them together around the stem C. of the flame spreader by means of two
screws which go into and attach the two ends of the wire which passes down the
central tube of the lamp and is the means for operating the disc as shown in
Figs. 1. 2. 3. 4. The disc is fastened in its top position by means of two pins D.
Fig. 1. projecting from the stern C. The disc having two slots on its inner edge
which allows the disc to pass the pins and the disc being partly turned by means
of the wire attached thereto, is now prevented from returning, Fig. 2. B. For
new lamps the disc may be made to act as both flame spreader and extinguisher,
being made in one piece as shown in Fig. 5.

COMPLETE SPECIFICATION.
An Extinguisher for Paraffin Oil Lamps with Central Air Passage
and Flame Spreader.
I EDWIN COMPTON Artist 46 Chapel Road Worthing Sussex 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 an extinguisher for paraffin oil lamps with central air
passage and flame spreader and it consists particularly in the application of a
circular disc of brass or other suitable material, immediately under the flame
spreader, which disc is pulled down upon the wick tube to extinguish the light
and may be returned to its normal position beneath the flame spreader by a spring
or otherwise; also in the adaptation of this disc to form both extinguisher and
flame spreader the ordinary flame spreader being dispensed with.
On the accompanying drawing :-
Figure 1 is a plan view of my extinguishing disc made in one piece ;
Figure 2 a similar plan view of my extinguishing disc, made in two parts;
Figure 3 is a section through the centre of disc as shown at Figure 2 ;
Figure 4 shows wires for operating the extinguishing disc;
Figure 5 shows the disc with operating wire attached;
Figure 6 is a section through a lamp showing extinguishing disc in its normal
position when not acting as extinguisher;

page_text: Figure 7 a similar section showing the disc in the act of extinguishing the
light.
A indicates the extinguisher or disc having a central opening a to give passage
to the stem C of the flame spreader B. For existing lamps I may make the disc A
in two halves as shown at Figures 2 and 3 with projections a¹ on the under side for
fastening them together around the stem C of the flame spreader by means of two
screws which also serve for attaching to the disc the two ends of the operating
wires F passing down the central tube of the lamp, see Figures 6 and 7.
Upon referring to the drawing left with my Provisional Specification it will be
seen that no spring is used for operating the disc but that the disc is secured in its
top position under the flame spreader by means of two pins D projecting from the
stem C, the disc A being provided with two slots (a³, a Figure 1 of the accom-
panying drawing) to permit it to pass these pins in being pulled down or pushed
up; when above these pins a slight turn given to the disc by the wires will prevent
its returning. I however now prefer to operate the extinguishing disc as shown
Figures 5, 6 and 7 of the accompanying drawing, where a spring E, is shown
attached at to the wires F and at g to wires G attached to the lamp at g'. The
extinguishing disc A being in its normal position as at Figure 6, on pulling the
ring H the disc A may be drawn down on to the wick tube as shown Figure 7
covering and extinguishing the light; on releasing the ring the spring E, which
has been clongated in the pull again contracts and returns the disc to its original
position under the flame spreader B as at Figure 6.
In the construction of new lamps I prefer to make the disc A in one piece as
shown at Figure 1 and it may if desired act both as flame spreader and extinguisher,
the ordinary flame spreader B being dispensed with.
Instead of a pull I may use a lever at the side to operate the raising and lowering
of the extinguishing disc and I may use any kind of slide or catch in lieu of the
returning spring and connection as above described and shown.
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. An extinguisher for paraffin oil lamps with central air passage and flame
spreader, consisting of a disc or plate arranged to work up and down upon the
stem of the flame spreader, substantially as described for the purpose specified.
2. An extinguisher for paraffin oil lamps with flame spreader having the
extinguishing disc or plate A operated by the wires F in combination with the
spring E and attachment G substantially as described and illustrated Figures 5, 6
and 7 of the accompanying drawing.
3. An extinguisher for paraffin oil lamps with flame spreader having an
extinguishing disc or plate A. operated to work up and down upon the stem C
without the aid of a spring substantially as described and shown on the drawing
left with my Provisional Specification.
4. An extinguisher for paraffin oil lamps with central air passage consisting of
an extinguishing disc or plate working up and down upon a central stem or
air tube and acting both as flame spreader and extinguisher substantially as set
forth.
