Improved Means for Automatically Extinguishing the Flame
of a Candle.
I STEPHEN TIMOTHY HARRINGTON, of Barnabely, Ringaskiddy, Cork, Ireland,
Farmer, 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 :-
My invention relates to improved means for automatically extinguishing the
flame of a candle, and has for its object an effectual means for automatically putting
out or extinguishing the flame of a candle when same has burned down to, or
reached a predetermined point.
And in order that my invention may be more readily understood, I have annexed
hereto a sheet of illustrative drawings, in which:-
Fig. 1 represents the extinguishing device in its earliest stage of construction,
or as it appears after being stamped or cut out of a single strip or sheet of metal.
Fig. 2 shows the extinguishing device bent into the requisite form and adjusted
upon a candle ready for action while
Fig. 3 represents the position the upper part of the appliance assumes, when it
has extinguished the flame of the candle.
The extinguishing device consists of a band or loop of thin steel or other metal a
possessing sufficiently resiliency to form a spring to enable same to press firmly
around the candle e and maintain itself at the desired altitude.
When the extinguishing device is cut or stamped out of the strip or sheet of
metal, two slits at a² are cut or stamped therein as shewn in Fig. 1, and near the
extremity of the branch or arm formed thereby, projects a dome-shaped disc
or cap, formed integrally with the whole, or joined thereto in any suitable
manner.
When the band or loop a is adjusted upon the candle, the edge of the dome-shaped
disc or cap presses against same forcing the said disc or cap to assume the
position shewn in Fig. 2.
The small strip or arm 62 is bent under across the underneath of the dome-shaped
disc or cap as shewn in Fig. 2, and serves to prevent the said dome-shaped disc
or cap (which forms the extinguisher proper) from pressing too directly upon
the heated and softened portion of the candle surrounding the wick, and by so doing,
protects the wick and softened portion of the candle from being flattened, and at
the same time prevents the extinguishing cap from getting clogged.
The periphery of the dome-shaped disc or cap which presses against the side
of the candle, will preferably be given a bevilled, or rounded form, so that it can
more easily slide upon the candle.
The action of the extinguishing device is as follows:-
The part a is passed around the candle e, being securely maintained at the
desired point by the resiliency of the metal, and the branch or arm b on which is
the dome-shaped dise or cap, and the small protecting or guide arm 62 is caused
to assume the position shewn in Fig. 2.
When the candle has burned down to the predetermined point the resistance
hitherto set up by the solid candle is removed and the resiliency of the metal
composing the branch or arm , causes same to spring inward, and so bring the
cap b' directly over the flaming wick, immediately extinguishing same, as shewn.
A handle e is provided for convenience in adjusting and handling the device,
and will be fixed to the body of the extinguisher by rivetting or other suitable
means.

page_text: A chain may also be provided for attaching the extinguishing device to the
candle-stick.
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:
A device for automatically extinguishing the flame of a candle consisting
essentially of the clip a and spring arm b provided with the extinguishing cap
and protecting arm 62 substantially as described, and illustrated in the accompanying
drawings.
Dated this 5th day of February 1892.
