IMPROVEMENTS IN NIGHT LIGHTS

"IMPROVEMENTS IN NIGHT LIGHTS

This invention has for its object improvements in night lights.
ว
In the manufacture of night lights it is common to mould the fatty material into
a block with a suitable wick in the centre then to form a paper case around the
moulded block and to supply a bottom by filling up the case with plaster of Paris.
My Patent Pyramid Night lights have been manufactured in this manner for
many years past.
According to my present invention I mould the block at that part where the
paper is wrapped around it of two diameters so that the paper may not fit closely
to the sides of the block at the end adjoining, the base. The paper case having
been applied the plaster is filled in and it then forms not only a base as heretofore
but also and in connection there with a thin casing around the sides of the block.
This casing of plaster is sufficiently transparent and it serves to ensure that the
whole of the fatty matter shall be melted and consumed which sometimes does not
take place when a paper case only is employed. The plaster bottom is made
concave so that the melted fat may gravitate towards the wick.
I can also make night lights with plaster of Paris cases by first casting the case
in a suitable mould and afterwards introducing the fatty material--but the method
of manufacture which I have previously described is that which I prefer.

This Invention has for its object improvements in night lights.
In the manufacture of night lights it is common to mould the fatty material
into a block with a suitable wick in the centre then to form a paper case around
the moulded block and to supply a bottom by filling up the case with plaster of
Paris.
My Patent Pyramid Night Lights have been manufactured in this manner for
many years past.
According to my present invention I mould the block at that part where the
paper is wound around it of two diameters so that the paper may not fit closely to
the sides of the block at the end adjoining the base. The paper case having been
applied the plaster is filled in and it then forms not only a base as heretofore but
also and in connection therewith a thin casing around the sides of the block. This
casing of plaster is sufficiently transparent and it serves to ensure that the whole
of the fatty matter shall be melted and consumed which sometimes does not take
place when a paper case only is employed.
The plaster bottom is made concave so that the melted fat may gravitate towards
the wick.
I can also make night lights with plaster of Paris cases by first casting the case
in a suitable mould and afterwards introducing in the fatty material but the
method of manufacture which I have previously described is that which I prefer.
In order that my said Invention may be most fully understood and readily
carried into effect I will proceed to describe the Drawings hereunto annexed

nearly to the top.
I claim:-
First As a new manufactured article a night light with a plaster case extending
more or less up the side of the block of fatty material and enveloped or not with
paper substantially as described.
Second-The process of manufacturing night lights consisting in moulding a
block of fatty material with an enlargement at the end remote from the base then
applying a wrapper around this block and pouring plaster therein thereby forming
a plaster case extending more or less up the side of the block of fatty material
substantially as described.
In witness whereof I the said Samuel Clarke have hereunto set my hand and
seal this fourth day of June in the year of our Lord One thousand eight hundred
and eighty four.
