PROVISIONAL SPECIFICATION.
Improvements in Argand or similar Oil Lamp Extinguishing
Mechanism.
We JOHN DENNIS YOUNG, of Taw Vale Parade, Barnstaple, Devonshire, Metal
Merchant, and HENRY BURGESS YOUNG, of 36 Dudley Street, in the City of
Birmingham, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in mechanism for the extinguishing of
Argand or cylindrical wick lamps automatically or by hand.
It consists as follows:- -We locate the operating parts of the mechanism below
the oil reservoir, contiguous thereto or at any other point therefrom, to the base.
Also we provide within the inner wick tube, a further tube which is capable of a
free sliding motion. At the upper end of this sliding tube is a cross or bridge
piece, to the centre of which is secured a vertical stem which extends upwards
through the burner, and terminates with a disc or spreader, whose outer diameter is
equal to or greater than that of the outer wick tube. The sectional shape of this
disc may be varied, but preferably it has an outer and inner downhanging flange, so
that when lowered on to the wick tubes, such flanges shall overhang the outer and
inner tubes.
At the lower end of the aforesaid sliding tube is the following mechanism :-At
the one side of the lamp stand, a fulcrum joint is made to receive a frame lever.
This lever extends along each side and beyond the aforesaid sliding tube, and
terminates with a cross wire rivetted or soldered thereto.
Upon the outer part of each of the sides of this lever is carried a weight for the
purpose hereinafter described. One of such sides is also extended beyond the
fulcrum to the exterior, so as to form a handle for manipulation at will. Beneath
the said lever (and as far from its fulcrum as convenient) is placed a lamina or
other spring suitably supported from the stand, whose tendency is always to lift the
said lever. Within this lever is a second frame lever, which extends from the inner
end of the first named lever also along each side of the sliding tube, and is carried
or fulcrumed in a bracket suitably carried upon the stand, such fulcrum lies about
midway in its length. The rear ends of the sides of this second lever are made
open slotted so as to take on to the wire cross piece of the first lever, while its other
end is connected to the sliding tube thus -to the side of the said tube is secured a
cross (collared) pin, and the ends of the sides of the lever being open slotted, such
slots take on to the ends of this pin.
Thus when the inner end of the first lever is raised, the farther end of the second
lever, with the tube is lowered, and vice versa.
Its action will now be understood to be as follows:-In the upright position of
the lanp, the weights on the first lever preponderate the power of the spring, and
the lever is thus kept in its lowest position, and in so doing of course the second
lever is subjected to the reverse action, that is, it is raised, and with it the sliding
tube together with the spreader or disc, to the usual working position. In case
however that the lamp is overturned, the action of the weight upon the spring is
neutralized and the latter is immediately free to raise the first lever and thereby
lower the second, which brings down the tube and with it the disc or spreader on to
the top of the wick, and thus put out the light. Upon the lamp being again set
upright, the parts fall back again into their working position and the lamp is ready
for relighting.
To extinguish by hand it is only necessary to depress the outstanding exterior
portion of the frame lever when the light will be extinguished in a similar manner.
This arrangement is suitable to most if not all the usual burners other than flat

page_text: wicks where a spreader or disc or its equivalent extinguisher may be operated from
below the oil vessel. It may also be placed' in the lower part of the burner or
between the burner and the vessel, but neither of these positions are so convenient
as that described.

COMPLETE SPECIFICATION.
Improvements in Argand or similar Oil Lamp Extinguishing
Mechanism.
We JOHN DENNIS YOUNG, of Taw Vale Parade, Barnstaple, Devonshire,
Metal Merchant, and HENRY BURGESS YOUNG, now of 40 Dudley Street, in
the City of Birmingham, Engineer, 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 improvements in mechanism for the extinguishing of
Argand or cylindrical wick lamps, automatically or by hand.
In order to explain this our invention, we have appended hereunto an illustrative
sheet of drawings upon which are figures and numbers of reference, similar numbers
referring throughout the several views to the same thing or part.
Fig. 1, is a sectional elevation of this our invention.
Fig. 2, is a part sectional plan view of this our invention on line A-B (Fig. 1).
Figs. 3 to 10 inclusive are detailed views of parts of the mechanism.
It consists as follows:-We preferably locate the operating parts of the
mechanism below the oil reservoir 1, in the basal portion of the lamp. Also we
provide within the inner wick tube 2, a further tube 3, which is capable of a free
vertical sliding motion. At the upper end of this sliding tube 3, is a cross or
bridge piece 4, to the centre of which is secured a vertical stem 5, which extends
upwards through the burner 6, and terminates with a disc or spreader 7, whose
outer diameter is equal to or greater than that of the outer wick tube 8. The
sectional shape of this disc 7 may be varied, but preferably it has an outer
downhanging flange 9, and an inner downhanging flange 10, so that when lowered
on to the wick tubes, as seen in Fig. 1, such flanges shall overhang the outer and
inner tubes 2 and 8.
At the lower end of the aforesaid sliding tube 3, is the following mechanism :-
At the one side of the lamp stand, a fulcrum joint is made to receive the pin 11,
of the frame lever 12. This lever extends along each side and beyond the
aforesaid sliding tube 3, and terminates with a cross wire 13, which is rivettedior
soldered thereto. Upon the outer part of each of the sides of this lever are
carried weights 14, 14, for the purpose hereinafter described. One of such sides
is also extended beyond the fulcrum 11, to the exterior, so as to form a handle 15,
for manipulation at will. Beneath the said lever (and as far from its fulcrum as
convenient) is placed a lamina or other spring 16 (suitably supported from the
stand) whose tendency is always to lift the lever 12. Within this lever is a second
frame levér 17, which extends from the inner end of the lever 12, along each side
of the sliding tube 3, and is carried or fulcrummed at 18, in a bracket 19, suitably
carried upon the lamp. The rear ends of the sides of this second lever 17, are
made open slotted at 20, 20, so as to take on to, and work upon, the wire cross
piece 13, of the first lever 12, while its other end is connected to the sliding tube.3,
thus-To tlie side of the said tube 3, is secured a cross pin 21, and the ends of
the sides of the lever being open slotted at 22, 22, such slots take on to the ends
of this pin 21. Thus when the inner end 13, of the first lever 12, is raised,
the end 22, of the second lever 17, together with the tube 3 is lowered, and
vice versa.

page_text: Its action will now be understood to be as follows In the upright position of
the lamp, the weights 14, 14, on the first lever 12, preponderate the power of the
spring 16, and the end 13, of the said lever is thus kept in its lowest position, and
thereby of course the second lever 17, is subjected to the reverse action, that is,
its end 22 is raised, and with it the sliding tube 3, together with the spreader or
disc 7, to the usual working position, as shown in dotted lines in Fig. 1.
In case
however that the lamp is overturned, the gravitating action of the weights 14, 14,
upon the spring 16, is neutralized and the latter is immediately free to raise the first
lever 12, and thereby lower the end 22, of the second lever 17, which brings down
the tube 3, and with it the disc or spreader 7, on to the top of the wick 23, as
shown in Fig. 1, and thus puts out the light. Upon the lamp being set
upright, the parts fall back again into their respective working positions, and the
lamp is ready for relighting. To extinguish by hand it is only necessary to depress
the outstanding exterior portion 15 of the frame lever 12, when the light will be
extinguished in a similar manner.
This arrangement is suitable to most if not all the usual burners other than flat
wicks where a spreader or disc or its equivalent extinguisher may be operated
from below the oil vessel, by means of a tube 3, or a rod performing the same
function. It may also be placed in the lower part of the burner or between the
burner and the vessel, but neither of these positions are so convenient as that
described.
The mounting of the wicks, and the winding mechanism for the same, also the
charging of the oil into the reservoir is effected in the ordinary manner, and forms
no part of this our invention.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:
In extinguishing mechanism for Argand or similar oil lamps, the combination
with the burner 6, wick tubes 2 and 8, and the spreader 7, having connected
thereto the sliding tube 3, of the levers 12 and 17, weights 14, 14, and spring 16,
constructed and operating substantially as described and shown upon the
drawings.
Dated this 20th day of April 1893.
