MENTS IN FLOATING NIGHT LIGHTS"
E
IMPROVE
This Invention has reference to that class of night lights in which the flame is
produced by means of a small cork disk through which a small wick passes and
which floats on the surface of the oil This method has many drawbacks, especially
that of the necessity of constantly renewing the wick, which latter is continually
subject to extinction from various uncontrolable causes
The object of this Invention is to remedy these defects by the abolition of the
usual wick and substituting therefore an everlasting one which is permanently
fixed and composed of durable substance
My improved night light consists of a metal bell in whose centre is a hollow
metal tube solidly fixed to the bell at the point indicated, in the centre of this
tube a second and glass tube is permanently fixed and adhering closely to the first,
this combination of the two tubes in conjunction with the bell forms the main
feature of the Invention The bell is made of a sufficient weight that when Hoating
on the oil this latter rises up the central glass tube and is there ignited, by this
means the employment of wicks is obviated, the tube taking its place, and is
practically everlasting
The bell, although here described as of metal, may be inade of any other durable
substance.

"IMPROVE-
The improvements in floating night lights here referied to relate to that class of
light where a floating wick is employed, such, for example, as a wax or other wick
inscited in a cork wheel or disk which floats on the oil contained in the lamp
There are drawbacks to the use of such lights on account of the necessity of constant
attention and renewal of the wick and want of cleanliness and liability of the wick
to upset in the oil and consequent extinction of the light
My Invention is intended to remedy these defects by so constructing the burner
as to obviate the necessity of employing a wick, the burner being rendered a per-
imanent and ever lasting one, wanting little attention, and being perfectly clean in
use These are the main features of advantage over those in present use
The apparatus consists of a small saucer or bell-shaped vessel made of either
metal, porcelain, or other substance, in the centre of this vessel is a tube, and
within this another glass one forming the burner, this vessel is made sufficiently
heavy to sink a little into the oil on which it is floated, in order that the oil may
be forced up the centre of the tube, there to be burned By this sunple method a
light may be kept burning any length of time by the use of a certain quantity of
oil, the weight of the saucer being sufhcient to keep the wick well and regularly
supplied, as the oil burns so the saucer descends, the oil being always maintained
at a level with the top of the central glass tube or buiner, thus superseding the
wick as employed in the class of lights above referred to
In the accompanying Diawings, Fig 1 represents a sectional elevation of the
saucer or vessel and central tube and burne, Fig 2 is a vertical elevation, and
Fig 3, a plan A is the floating vessel, B, the central metallic tube, and C, the
glass tubo or buiner
What I claim is the floating vessel A. in combination with the central tube B and
glass burner C, as and for the purposes herem-before mentioned
In witness whereof, I, the said Charles Bonnes, have hereunto set my hand
and seal, this Twenty-thnd day of July, in the year of our Lord One
