Improvements in Extinguishers for Lamps, Stoves, and the like.
I, MARIE ANGEL ALPHONSE REVEILHAC, of 31, Boulevard Henri IV., Paris,
in the Republic of France, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
.
This invention relates to improvements in extinguishers for lamps, stoves and
the like applicable to all kinds of lamp burners and stoves including hollow wick
lamps, disc burners, whatever may be the tubular form of the wick tube or
burner whether cylindrical, conical, truncated-conical etc. or the improvement
may comprise the combination of each of these shapes whether these lamps or
stoves burn mineral oils such as schist, petroleum, volatile oils, etc., or even
vegetable oil whatever may be the size of the burner.
The improved extinguisher is constructed of two tubes one of such tubes being
placed within and the other outside the burner. By means of a lever these two
tubes can be caused to suddenly rise around the wick and thus extinguish the
flame.
In order to enable the invention to be fully understood I will describe the same
by reference to the several figures of the accompanying drawing.
In the arrangement shewn in Figures 1 and 2 the outer tube C of the burner
is enclosed within a tube formed in two parts D D' connected to an inner tube m
by a rod T to which is fixed a small transverse rod t, passing freely through two
eyes formed in the parts D, D. The bent rod T is connected to the base of
the inner tube m.
Each of the parts D, D' is provided with a slot U in which pass guides G
which maintain each of these parts D, D¹ against the tubes C whatever position they
may occupy.
The upward and downward movements of the extinguisher comprising the
tubes D, D and m are effected by a lever A. having a fork B movable around a
pivot a. The ends of the fork pass through cars or lugs f on the tube D, D¹.
The part D carries a luge into which freely passes a finger on the part D¹.
The lamp being lighted and the extinguisher in the position shewn in Figure 1
if the lever A. be depressed it will turn on the pivot a, and by means of the fork B
raise the tubes D D¹ and m, and extinguish the flame of the burner C. The
pivot a of the lever A is fixed to the basket of the burner.
The arrangement shown in Figures 3 and 4 differs from that just described in
that the two parts D D' forming the outer tube of the extinguisher are not
separated at both sides when the extinguisher is in its normal position but at one
side only, the parts being in contact on the opposite side. These two parts D D¹
are connected by means of a spring i soldered or otherwise suitably connected at
each end to the parts D D₁ and which by reason of its curved form when the
extinguisher is raised causes the parts D D opposite this spring to come together.
The operation of this extinguisher is the same as that described with reference
to the arrangement shewn in Figures 1 and 2; its extent of movement is limited
by a stop fixed to the burner and moving in a guide formed between the
parts D D beneath the spring i.
In some cases this spring may be replaced by a hinge but in this case in order
to effect the bringing together of the two parts Ď D' the two arms of the lever A
should form a spring of suitable curvature whereby a two-fold result would be
obtained, videlicet, (1) the raising of the extinguisher, and (2) the bringing together
of the two parts D, D'.
This outer tube 'may also be made of a single piece of metal sufficiently flexible
to form a spring. In this case the tube would be cut at one side only which

page_text: would allow of it opening when returned to its normal position on a truncated-
conical tube.
The arrangement shewn in Figures 5 and 6 differs from those already described
and possesses the further advantage of being removable thus rendering the cleaning
of the lamp or sto more easy. This extinguisher is especially applicable to
cylindrical truncated-conical burners and is constructed of two cylindrical tubes
each made in one piece, one tube m enclosing the other tube n. The tube m
carries at its base four arms, two of which receive movement from the arms
of the lever A. A third arm m² serves to limit the extent of movement of the
extinguisher and the fourth arm m³ renders the tube m of the inner tube n firm
by means of the curved rod I fixed to the inner tube. The outer tube m is made
removable by means of bayonet joints formed on the lower ends of the arms m², m³.
In some cases only the cylindrical part is made removable as shewn in Figure &
in which case the tube is provided with two, three or four catches which take into
as many bayonet slots. In some cases the tube could be firmly fixed to the arms
by a screw thread. The gallery may be connected to the basket of the burner
by a screw thread or it may fit on the same like the cover of a box as shewn in
Figure 7.
Figures 9, 10 and 11 illustrate the application of the improved extinguisher to
cylindrical burners of the kind shown. In this arrangement the extinguisher is
constructed of two superposed cylindrical tubes E and F and connected to each
other. by bayonet fastenings. As above explained, in Figure 9 the upper tube is
provided with a bayonet fastening to allow of the wick being replaced when
desired. The operation of this extinguisher is similar to that shewn in Figures 5
and 6. Figure 9 shews the lamp burner arranged in a removable gallery but the
basket of which has likewise been rendered removable by means of a bayonet
fastenings. This improvement is necessitated by the suppression of the screw
thread which interferes with the movement of the gallery.
In cases where the extinguishing of the flame can be effected without the
necessity of employing the inner tube or when the burner is deprived of an internal
current traversing the centre of the flame I dispense with the inner tube and
employ only the outer tube.
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 cylindrical or truncated-conical burners comprising an
external tube formed in two or several parts D D which is normally beneath the
level of the burner, in combination with a lever for quickly raising, such tube for
the purpose of extinguishing the flame substantially as hereinbefore described.
(2.) In an extinguisher to be used with truncated-conical and other burners,
the combination of an outer tube in two or more parts D, D₁ provided with slots U
to receive guides G with an inner tube m, by the intervention of rods and T in
the manner and for the purpose above described.
with a forked
(3.) In an extinguisher for truncated-conical and other burners the combination
of an outer tube in two or more parts D D¹ and an inner tube
lever A substantially as hereinbefore described.

(4.) The various arrangements for extinguishing lamps and stoves hereinbefore
described and illustrated in the several figures of the accompanying drawings.
(5.) The application of the arrangement of lever to tubular extinguishers having
two tubes or to a single outer tube whether such tube be in one or more parts
substantially as hereinbefore described.
