Improved Means for Extinguishing Oil Lamps.
I, MICHEL RASSIAT of La Roche Hte. Savoie, France Waiter, 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 improved means for extinguishing oil lamps, and has for
its object to provide a safety or automatically extinguishing lamp should the latter
be accidentally overturned.
For this purpose I attach by small chains two balls or weights to a ring supported
by the gallery of the lump. These balls rest upon rings or supports outside the
gallery, carried by a ring or plate surrounding the central tube of the burner,
which ring or plate is attached by wires to two curved plates pivoted together and
forming a hood or extinguisher when raised above the level of the burner tubo.
The said hood is pivoted to two rods or wires passing through holes in the ring or
plate under which their ends are curved. These rods or wires are formed with
projections which bear against a projecting part of the gallery when the ring or
plate is raised by means of a coiled spring underneath it upon the balls or weights
falling off their supports when the lamp is inclined or upset, the raising of the said
ring or plate also raising and closing the hood above the top of the burner hood.
In the accompanying sheet of drawings,
Fig. 1 is an elevation, partly in section of the upper part or burner and gallery
of a lamp, having a round wick or "Argand" burner, according to my invention,
with the extinguisher in its lowered position and Fig. 2 is a similar view with the
extinguisher raised.
Fig. 3 is a separate view of the extinguisher and its connections at right angles
to Fig. 2.
a a are two balls attached by small chains a¹ a¹ to a wire ring 6 supported by the
gallery c. When the lamp is burning the balls rest upon rings or supports d d
carried by a ring or plate e surrounding the central tube or burner f. The ring e
is connected by wires g g to two curved plates h h forming a hood or extinguisher,
the said plates being pivoted at h¹ to two rods or wires ii passing down through
holes in the ring e underneath which they are curved upwards at 1, These rods
or wires are bent or formed with projections, and underneath the ring e is a
coiled spring & tending to force the said ring upwards.
The operation is as follows. The balls a being placed in position upon the
rings d the hood or extinguisher is kept in its lowered position just below the top
of the burnerf as shown in Fig. 1 but should the lamp be tilted over or upset the
balls roll off the rings d thus permitting the spring k to force up the ring or plate e
and with it the extinguisher and its connecting rods or wires g and i until the
projections hear against the shoulder c¹ of the gallery thus preventing the further
ascent of the rods which by the continued ascent of the ring e and wires a causes
the latter to tilt or turn on their pivots the plates & forming the hood until they
meet together and close over the burner as shewn in Fig. 2 theroby effectually
extinguishing the light. By simply removing the balls a from their supports d the
light may be extinguished without tilting the lamp.
It is evident my invention may be applied to flat wick burners as well as round
oues by substituting flat extinguisher plates for the curved ones hereinbefore
described.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is.
(1.) In oil lamp extinguishers the combination of the balls or weights a attached
to a ring b and 'the supports d extending outside the gallery c, the ring or plate e,
the wires g the pivoted plates & forming the extinguisher, the rods or wires i formed
with projections and the spring & substantially as described and for the purposes
specified.
(2.) The improved oil lamp extinguisher substantially as described and shown in
the accompanying sheet of drawings.
