COMPLETE SPECIFICATION.
An Automatic Candle-extinguisher.
I, JOSEPH COLLIS BAYLEE of Church Road, North, Portishead, Somerset,
Gentleman, 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:-
The appliance for automatically extinguishing the flames of burning candles
which constitutes this invention consists of a sleeve designed to encircle the candle,
to which sleeve is connected, by a spring hinge, an extinguishing hood or cap.
The hood is furnished with a pawl by means of which the hood is held out of
action on the candle and by means of which also the sleeve may be set
on the candle at any point in its length, thereby determining when the hood shall
come into operation to extinguish the flame; this action resulting from rebound of
the hood following on the softening of the candle and consequent release of the
pawl.
Referring to the accompanying drawings,
Fig. 1 represents a view of the candle-flame extinguishing appliance which
constitutes this invention.
In this view the extinguishing hood or cap is shown tilted down.
Fig. 2 shows the hood closed on the sleeve, that is to say, in the extinguishing
position.
Fig. 3 is a view at right angles to Fig. 2.
The appliance which is made of sheet iron, steel, brass or other suitable metal,
consists of a sleeve a for encircling the candle C. To the sleeve a is hinged the
hood or hollow cap b furnished with a pawl c. A spring is coiled around the hinge
pin d of the hood b, one end of the spring being secured to the said hinge pin d
and the other to the pawl, which latter is looped about the hinge pin d to constitute
the hinge of the hood or cap b. In practically using the appliance, the hood or
cap b is first tilted downwards and the sleeve a is then put on the candle. The act
of tilting the hood tightens the coiled spring aforesaid. When the sleeve has been
adjusted to the desired position on the candle, it is held in that position by the tail
of the pawl c which bears, under the influence of the coiled spring aforesaid,
(indicated in dotted lines at Fig. 1) against the candle, as seen at Fig. 1. When
the candle has burnt down to a point sufficiently near the tail of the pawl c so as
to soften the material of which the candle is made to an extent which enables the
spring of the pawl to rebound, this action takes place, the pawl being no longer
restrained by the candle. Rebound of the spring causes the hood or cap 6 to
rise and close, as seen at Figs. 2 and 3, over the candle flame which is thus
extinguished.
A clamping screw may be fitted to the sleeve so as to enable it to be clamped
on candles of diameter so much smaller than the sleeve as to require such a device
to hold the pawl tail up to the candle.
The sleeve may be divided vertically so as to form a spring clip, or a screw or
locking clip for binding on the candle.
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
An appliance for extinguishing candles, cousisting of a sleeve such as a, or its
equivalent, connected by a spring hinge to a hood or cap such as 6 furnished with

page_text: a pawl such as c to which is connected one end of a spring coiled round the hinge
pin to which the other end of the spring is connected; the arrangement being such
that by the melting or softening of the candle, the extinguisher is brought into
action to extinguish the flame, substantially as hereinabove described with reference
to the accompanying sheet of drawings.
Dated this 3rd day of September 1896.
