PROVISIONAL SPECIFICATION.
An Automatic Extinguisher for Candles.
I, EDMUND SZANDTNER of Pressburg, Hungary, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is a device for automatically extinguishing burning
candles after a certain time. The improved device essentially consists of a tube
adapted to be shifted on the candle and carrying a spring which lays itself onto
the circumference of the candle. To said tube which is widened above is hinged
a lid or cap.
A spiral spring is so provided at the lid and hinge arm of the tube
that the lid tends to close the tube. The lid has a pin, by means of which, when
it is turned out sufficiently, the lid is held open by the spring which is in contact
with the candle laying itself against the pin and the nose thereof.
When the candle is burnt down so as to release the spring, the latter moves
away from the nose and the lid closes by the action of the spiral spring. By the
air pressure caused thereby the flame is instantaneously extinguished.
The lid may also be arranged to close horizontally so that the flame is extinguished
by being deprived of oxygen.

COMPLETE SPECIFICATION.
An Automatic Extinguisher for Candles.
I, EDMUND SZANDTNER, Manufacturer, of Pressburg, Hungary, 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 a device for automatically extinguishing burning
candles after a certain time, or after a given length has been consumed.
In the accompanying drawings,
Fig. 1 is a side elevation and Fig. 2 a plan of a candle and extinguisher
embodying my invention;
Figs. 3 and 4 are back elevations in different positions or conditions of the
extinguisher.
Fig. 5 is a plan of Fig. 4, and
Fig. 6 shows a modification.
The improved device chiefly comprises a tube a adapted to be shifted on the
candle and carrying a main spring which lays itself on to the circumference of
the candle (Fig. 2). To said tube, which is widened above, is hinged a lid or cap c.
A helical spring d is so applied to the lid and hinge arm of the tube, that the lid
tends to close the tube. The lid has a pin f and catch e by means of which, when
it is turned out sufficiently, the lid is held open by the spring which is in contact
with the candle, said spring laying itself against the pin and the catch e thereof.
(Fig. 3.)
When the candle has burned down to such an extent, as to release the spring b,
the latter moves away from the catch e, and the lid closes by the motion of the
spiral spring d. The air pressure caused thereby serves to extinguish the flame.
This position is shown by Figs. 4 and 5.

page_text: The lid may also be arranged to close horizontally, instead of vertically, so that
the flame is extinguished by being deprived of oxygen.
This modification is shown by Fig. 6, in which the lid is pivoted on a vertical
hinge and therefore turns in a horizontal plane.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
An automatic candle extinguisher comprising in its construction a main spring b
and an automatically closing lid c, the said spring being adapted to retain the
lid in its open position, until the candle has burned down a given distance, after
which the lid is set in action under the influence of a spring d, so as to extinguish
the flame either by air pressure or by the exclusion of air, substantially as
described.
