An Improved Automatic Candle Extinguisher.
A communication from GEORGE MCNEILL ROBB, of Sydney, in the Colony of
New South Wales, Pattern Maker.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 has been specially devised for the purpose of allowing a candle
to burn for a given time and shall then be automatically extinguished. For
instance, a person might desire to read in bed for a space of time equal to the
consumption of one inch of candle, in which case the extinguisher would be set
so as to allow one inch of the candle to be burnt before being automatically
extinguished.
The invention consists of a metallic collar that is provided with two bent spring
arms that meet together overhead. When the candle is fixed in position the collar
will be slipped on to the candle and the topmost points of the spring arms will be
fixed at the point in the candle where the extinction is to take place.
In the accompanying drawings
Figure 1 shews a piece of metal stamped out so as to form a blank from which
the extinguisher is to be shaped.
Figure 2 is a side elevation of the blank shaped.
Figure 3 shews the shaped appliance fixed in position on the candle.
Figure 4 shews another form of blank.
Figure 5 shews the same blank shaped.
Figure 6 shews in plan the same blank shaped.
Figure 7 shews the same shape of blank fixed on the candle which it has just
extinguished.
In Figure 1, a is a central enlargement that forms the collar that fits over the
stem of the candle. The central portion of this enlargement is starred or cut into
segments b that may be turned up so as to give a loose grip on to the body of the
candle as shewn in Figures 2 and 3. The arms c are bent over in a curve, while
the extremities d are bent upwards as shewn in Figure 2 for a
hereafter explained.
reason to be
Figures 4 to 7 show a somewhat different form of blank, but which, when bent
into shape, will form a similar article to that shown in Figs. 1 to 3 except that
the collar e will be cylindrical in form and flanged at the bottom. When it is
desired to use the extinguisher it will be fixed on the candle as shown in Fig. 3,
the points d being placed at the point on the candle where the extinction is to
take place. On the candle burning down to the point where the points d loosely
grip the stem of the candle the spring arms c will force the points d inwards so
that they shall grip the wick and thus extinguish the candle, as shown in Fig. 7.
The points d are turned upwards so that they shall not scoop up any of the melted
tallow or wax, that lies on the top of the candle, but, passing clear of such melted
tallow or wax, shall grip the wick between their edges and thus extinguish the
light. Although two forms of blanks are shown, my correspondent wishes it to be
understood that he does not confine himself to any particular form of blank.

page_text: Having now particularly described and illustrated the nature of this invention,
as communicated to me by my foreign correspondent, and in what manner the same
is to be performed, I declare that what I claim is ;-
1. A collar that shall be made to fit and loosely grip the stem of a candle the
said collar being provided with lateral springy curved extensions or arms that meet
together overhead as herein described.
2. In combination a collar that shall approximately fit or be made to loosely
grip the stem of a candle two or more laterally projecting curved springy arms,
that shall meet at one point overhead the topmost extremities or gripping
parts of such springy arms bending upwards all as and for the purposes herein
set forth.
