PROVISIONAL SPECIFICATION.
An Improvement in connection with the Extinguishing of
Oil Lamps.
JOHN WILLIAM POST of Gyffin Road Conway, Carnarvonshire, Poor Law
Clerk &c., and WILLIAM CARTY of Gyffin Road, Conway, Carnarvonshire,
Plumber &c., do hereby declare the nature of this invention to be as follows:-
An improvement in connection with the extinguishing of oil lamps. The
improvement consists of an article made of brass (or any other suitable material)
which will fit round the wick tube under the cap or dome of the lamp, and it
automatically extinguishes the light upon the wick being turned down, thus
rendering it unnecessary to blow the light out in any way whatever after turning
down the wick, which would do away altogether with the risk of explosion so often
caused by such blowing.
The said article as above stated fits round the wick tube & it (principally) consists
of two pieces of brass as broad as the wick tube, which are so made that when the
wick is lowered, they close by means of two slight springs over the top of the wick
and so put out the light.

An Improvement in connection with the Extinguishing of
Oil Lamps.
We, JOHN WILLIAM POST of Gyffin Road Conway, Carnarvonshire, Poor
Law Clerk &c. and WILLIAM CARTY of Gyffin Road, Conway Carnarvonshire,
Plumber &c. do hereby declare the nature of our 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
An improvement in connection with the extinguishing of oil lamps.
improvement consists of an article made of brass (or any other suitable material)
which will fit round the wick tube under the cap or dome of the lamp, and it
automatically extinguishes the light upon the wick being turned down, thus
rendering it unnecessary to blow the light out in any way whatever after turning
down the wick, which would do away altogether with the risk of explosion so often
caused by such blowing.
The said article as above stated fits round the wick tube and it (principally)
consists of two pieces of brass as broad as the wick tube or a little broader which
are so made that when the wick is lowered they close over the top of the wick by
the action of springs, and so put the light out.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a double sized sheet of drawings
upon which we bave illustrated an example of one of our extinguishing arrange-
ments as applied to an ordinary lamp but it must be clearly understood that it is
capable of very wide application as for instance to the lamps of oil stoves whether
.

page_text: for cooking or warming purposes as hitherto considerable difficulty has been
experienced in extinguishing these whereas with our inveution it is only necessary
to turn down the wick or wicks. The application to such like and similar objects
will be obvious.
Figure 1. is an elevation of a lamp burner having our extinguisher fitted thereto
with a piece of the front broken away so
to expose
extinguisher.
one side of our
Figure 2. is a sectional elevation of the lamp burner B at right angles to
Figure 1 and showing the wick W raised to a considerable height indeed higher
than when in use.
Figure 3. is a similar sectional elevation to Figure 2 but showing the wick W
screwed down low and the extinguisher A, A' closed over the wick W.
Figure 4. is a plan of the wick W and extinguisher A, A¹ open as it is when the
wick W is in position to light.
Figure 5. is a broken off sectional elevation of a portion of the lamp B but with
the extinguisher A, A' enlarged in scale and also showing a modified form of
fixing.
Figure 6. is a perspective view of the extinguisher and with case w¹.
Figure 7. is a broken off perspective view of the inside of the part A' of the
extinguisher.
For the purpose of illustrating our invention we have shown a portion of an
ordinary lamp burner B with our extinguisher applied thereto but the application
will be similar in all the essential parts to an ordinary lamp stove. B is the base
of a burner for a lamp having the ordinary wick case wi which is shorter than
usual and fitted with the wick W and the ordinary ventilating disc or grating b'.
Now our extinguisher consists of two main portions or sides A and A' which are
hinged or pivotted at a³ to a plate or base a³ or the grating 6' may form the base
for the hinges a³ as shown at the enlarged view Figure 5. One of the sides of the
extinguisher A is made with ends a' as seen at Figure 7 and as shown in other
figures as for instance Figures 4 and 6, and the other part A fits loosely inside these
ends. By means of the light spring a' or a similar spring or springs differently
placed the normal tendency of the two flaps A and A' is to close together as seen
at Figure 3 and therefore when the wick is up and lighted the flaps are open as
seen at Figures 1, 2, 4 and 5 and the flaps exert a slight pressure upon the wick.
The flaps are however formed with a hollow at a and flat for a short distance at a
which practically constitutes a continuation of the wick tube w¹ and is indeed for all
practical purpose the equivalent of a wick tube near the burning portion of the
wick w. It will therefore be understood that by screwing down the wick as seen at
Figure 3 or a much less distance than there shown that the extinguisher A, A¹
closes as there seen and the lamp is effectively extinguished. To relight the lamp
it is only necessary to screw up the wick by the screw K, when the wick may be at
once relighted. The formation of the tops a, a of A and A' is such that the
wick easily slides between and through them the wick being amply strong to make
the action effective and sure. By these means we dispense entirely with an extra
extinguisher with its lever and parts and yet effectively provide all that is necessary
for the purpose.
It will be obvious that our invention may be applied to any number of wicks
and that it may be any desired length and in any number of lengths with a spring
or springs connected to each as desired by the particular circumstances of each case.
An approximation to our extinguisher may be made without the ends a' and with
less or more bend than shown by a' but we have shown what we have found to
answer well in practice.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
The improvement in connection with the extinguishing of oil lamps or stoves or

page_text: similar burners consisting essentially of the parts A and A' mounted and operated
by a spring arrangement or springs substantially as and for the purpose herein set
forth and as shown upon the drawings by Figures 1 to 7 inclusive.
