PROVISIONAL SPECIFICATION.
An Improved Means for Extinguishing Argand Oil Lamps.
EDWIN COMPTON, Artist, 46 Chapel Road, Worthing, Sussex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improvement in the shape of the disc used in the
extinguisher for parrafin oil lamps. With circular wick & central air tube with
flame spreader which is more particularly refered to in the Specification filed
Oct. 28/91 No. 17838. The improvement consists of forming the disc with a
circular channel the outer edge of which is the same diameter as the outer wick
tube & its inner edge the same diameter as the inner wick tube.
The object of the channel around the disc is to allow its inner & outer edges
to touch the top edges of the inner & outer wick tubes, & so extinguishes the
flame, the channel forming a space for the wick, so that the wick need not be
lowered, when it is required to extinguish the flame.
Fig. 1. in the accompanying drawings represents a plan of the disc, the hole in the
centre A is to allow the disc to pass up & down the stem of the flame spreader.
The circle B. is the inner edge of channel.
Fig. 2. is a section of the disc through the centre C. C. being the channel.
Fig. 3. at E. shows one method of attaching the wires by hooking them over the
inner edge of the disc, the wires lying in the slots shown at D. D. Fig. 1.
Fig. 4. shows the wires separate.
Fig. 5. shows the disc in position as extinguishing the lamp.

COMPLETE SPECIFICATION.
An Improved Means for Extinguishing Argand Oil Lamps.
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 per-
formed to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improved means for extinguishing "Argand" oil
lamps, that is to say, lamps burning paraffin and other oils having a circular wick
and central air tube with flame spreader.
In the Specification left with my application for Letters Patent No. 17,838 of
1891, I described an extinguisher consisting of a movable disc, or plate applied
immediately under the flame spreader which disc might be pulled down upon the
wick tube to extinguish the light and be returned to its normal position beneath
the flame spreader by a spring or otherwise.
My present invention consists in forming the said extinguishing disc with a
circular channel the outer edge of which is of the same diameter as the outer wick
tube and the inner edge the same diameter as the inner wick tube, with the object
of allowing the inner and outer edges to touch the top edges of the inner and outer
wick tubes and so extinguish the flame, the channel forming a space for the wick,
so that the wick need not be lowered when it is required to extinguish the flame;
this invention also consists in a particular method of attaching the operating wires
to the disc and of actuating the same to lower and to return the disc.

page_text: Referring to the accompanying drawing :-
Figure 1 is a plan view of my extinguishing disc shown detached;
Figure 2 is a section through the centre of said disc;
Figure 3 shows wire support for carrying extinguishing disc;
Figure 4 shows same support attached to disc;
Figure 5 shows the normal position of the disc when it is not acting as ex-
tinguisher;
Figure 6 shows the disc in the act of extinguishing the light.
A indicates the extinguishing disc having a central opening a to give passage
to the stem b of the flame spreader B. C, C, (Figure 2) channel around the disc A
to allow its inner edge c and outer edge c¹ to touch the top edges of the inner and
outer wick tubes D, D' when lowered as at Figure 6. E, wires supporting disc A
to which their ends e, e are attached by being passed into the slots f, f Figure 1;
these wires E are twisted together at g and bent into a ring forming pull to
actuate the disc. F is a spiral spring attached to the wire E at i and to the stem b
of the flame spreader at k.
The extinguishing disc A being in its normal position as at Figure 5, on pulling
the ring this disc A may be drawn downward to the position shown Figure 6
where it entirely covers the wick and extinguishes the light, on releasing the ring
the spring F which has been elongated in the pull again contracts and returns the
disc to its original position under the flame spreader B as at Figure 5.
It will be seen that the channel C, C, forms a space in the disc A. to receive
the wick so that the wick need not be lowered when it is desired to extinguish
the flame.
My disc A having the channel C may if desired form both extinguisher and flame
spreader, the flame spreader B being dispensed with.
It will be found that the channel C not only secures the extinguishing of the
flame but also to a considerable extent trims the wick for relighting as it leaves it
with a perfectly uniform top edge.
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
1. An improved means for extinguishing Argand oil lamps consisting of the
disc A having the circular channel C so formed that when the disc is lowered
the inner and outer edges c, e¹, of the channel will come on to the top edges of the
inner and outer wick tubes D D' and thereby extinguish the flame all substantially
as described.
2. In an Argand oil lamp having the extinguishing disc A, the attachment of the
operating wires E E to the disc by passing their ends shaped as at e, e, into the
slots of the disc, also the combination of the spring F with the wires EE
and the air tube or stem 6 of the flame spreader, all constructed combined
and arranged to operate substantially as hereinbefore described for the purpose
specified.
