PROVISIONAL SPECIFICATION.
Improvements in Night Lights.
I, SAMUEL CLARKE, of the Pyramid Works, Childs Hill, in the County of
Middlesex, Night Light Manufacturer, do hereby declare the nature of this invention
to be as follows:-
Heretofore short candles known as night lights were made with a 'thin wick
running through from end to end-sometimes made with the wick cast in them or
with a hole through them for a wick to be placed in afterwards. With this method
it is very difficult to obtain a successful result when the night lights are made
of a material of high. illuminating power such as paraffin wax or other similar
material.
My invention is to make short candles to be used as night lights or for other
purposes with a short and comparatively thick wick passing only a short distance
down the candle and held in a float so that when the material melts the wick will
float on the top of the melted material. The wicks and floats may bo cast in the
candles or the candles may be made with an indentation at the top so that the wick
and float could be placed in afterwards.
Preferably I use a float formed of a ring of cork or other light material carrying
a disc of very thin sheet metal through the centre of which is a hole for the wick to
pass through and which has arms extending outwards. from it nearly to the sides of
the paper or other casing within which the block of paraffin or combustible material
is contained so as in this way to maintain the wick always near the centre of the
casing. The brightness of light given by the nightlights when burnt can be regulated
by the length of wick left above the top of the thin.metal. disc.

COMPLETE SPECIFICATION.
Improvements in Night Lights.
I, SAMUEL CLARKE of the Pyramid Works, Childs Hill in the County of Middlesex,
Night Light Manufacturer, 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 :—
Heretofore short candles known as night lights were made with a thin wick
running through from end to end-sometimes made with the wick cast in them or
with a hole through them for a wick to be placed in afterwards. With this method
it is very difficult to obtain a successful result when the night lights are made
of a material of high illuminating power, such as paraffin wax or other similar
material.
My Invention is to make short candles to be used as night lights or for other
purposes with a wick held in a float so that when the material melts the wick will
Boat on the top of the melted material and allow it to descend as the material melts
and thereby obviate the danger of the wick falling against the side which it is liable
to do when paraffin wax or other material that melts at a low temperature is used.
The wicks and floats may be cast in the candles or the candles may be made with an
indentation at the top, so that the wick and float could be placed in afterwards.
Figure 1 of the drawings annexed is a vertical section and
Figure 2 a plan view of a night light or short candle formed in the manner I prefer
for carrying out my Invention.

page_text: A is a disc of cork with a hole formed through its centre. B is a disc of very
thin sheet metal or foil with parts cut out from its outer circumference as shewn to
reduce its weight. Cisa cup also of thin sheet metal on the top of the disc B and
having an oblong hole formed through it. D is a wick passed through the holes in
the discs.
In making the night light, the several discs with the wick threaded through them
are dipped in melted material and fixed on to the bottom of a mould such as Figure 3
and the filling of the mould is subsequently completed in the ordinary way.
1"
The bottom of the mould may be shaped in the manner shewn.
In place of the float being formed with a cup C as shown at Figures 1 and 2 it
might simply be formed of a star-shaped piece of sheet cork covered with thin metal
foil as shewn at Figures 4 and 5.
The wick used, may either be a short wick as shewn in these figures or a longer
wick may he used as shewn in Figure 1.
The brightness of light given by the night lights when burnt can be regulated by
the length of wick left above the top of the thin metal disc which is on the top
of the float.
As' above stated the candles may be made separately with an indentation or hollow
at the top for a float carrying a wick to be dropped into when the candle is to be
lighted a candle so formed to receive a float and wick is shewn at Figure 6. The
small quantity of candle material contained within the cup C will when the wick is
lighted be sufficient to supply the wick until the material of which the candle is
formed itself commences to melt.
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
1. A night light or short candle having its wick sustained near its upper end by
a flat substantially as described.
2. A night light or short candle the wick of which is sustained by a float which
lies at the bottom of a hollow formed in the top of the candle.
..
3. The construction of night lights or candles substantially as hereinbefore
lescribed..
