Engineer do hereby declare the nature of this invention to be as follows:-
A piece of mechanism to extinguish a candle at any point of its burning. This
is attained by a light apparatus fixed to the candle or candlestick, easily placed
and easily removed, it can be set so as to put out the candle at any desired time.
Reference to the drawings will make this clear. Figure 1 is a side elevation.
Figure 2 an end view. Figure 3 a top view. All the letters of reference are the
same for the same parts in the several figures. A is a clip which is fastened to the
candle or candlestick by means of a spring wire K which turns in the clip A and
is unfastened by moving the ends up or down. B is an extinguisher jointed by
means of an arm to the clip A at C. D is a wire or trigger jointed to the arm of
the extinguisher B at E. The trigger has a sharp point L on the side, which can
be pressed into the candle at the required distance from the top to burn the time
desired. The trigger has a weight F sufficiently heavy to tilt the trigger, when
the candle has burned down to the point where the trigger was inserted into the
candle. On the clip A, is formed a curved check G, on which a stop H, fastened
to the trigger, moves so that, while the trigger is free to rise, the extinguisher
cannot fall until the trigger has moved sufficient for the stop H to clear the fixed
curved check G. The curve of the check G is described from the centre of motion
of the trigger when the arm carrying the extinguisher is touching the stop J.
Upon the trigger rising sufficiently, the extinguisher descends by gravity and
extinguishes the candle.
To set the extinguisher for action, it is lifted until the arm touches the stop J in
which position the stop H on the trigger can be moved on to the curve G, and the
point L may be inserted into the candle at the point desired.

Engineer do hereby declare the nature of my invention for SELF-ACTING CANDLE
EXTINGUISHER and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention consists of mechanism to extinguish a candle at any period of its
burning. This is attained by a light apparatus fixed to the candle or candlestick
easily placed and easily removed, and can be set so as to put out the candle at
any desired time of its burning. Reference to the drawings accompanying my
Provisional Specification will make this clear. Figure 1 is a side elevation.
Figure 2 an end view. Figure 3 a top view. All the letters of reference are
the same for the same parts in the several figures.
A is a clip which is fastened to the candle or candlestick by means of a spring
wire K which turns in the clip A and is unfastened by moving the ends up or
down. B is an extinguisher jointed by means of an arın to the clip A at C. D is
a wire or trigger jointed to the arm of the extinguisher B at E. The trigger has a
sharp point L on the side, which can be pressed into the candle at the required
distance from the top to burn the time desired. The trigger has a weight F
sufficiently heavy to tilt the trigger, when the candle has burned down to the
point where the trigger was inserted into the candle. On the clip A, is formed a
curved check G, on which a stop H, fastened to the trigger, moves so that, while
the trigger is free to rise, the extinguisher cannot fall until the trigger has moved
sufficient for the stop H to clear the fixed curved check G. The curve of the
check G is described from the centre of motion of the trigger when the arm
carrying the extinguisher is touching the stop J. Upon the trigger rising
sufficiently, the extinguisher descends by gravity and extinguishes the candle.
To set the extinguisher for action, it is lifted until the arm touches the stop J in
which position the stop H on the trigger can be moved on to the curve G, and the
point L may be inserted into the candle at the point desired.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is,
1st. The general arrangement shewn, and any similar arrangement.
2nd. The trigger.
