We, JOHN FYFE, Managing Director of Young's Paraffin Light and Mineral Oil
Company, Limited, of Glasgow, in the County of Lanark, North Britain, and
WILLIAM MCCUTCHON, Manager of the Addiewell Works, West Calder, in the
County of Mid Lothian, North Britain, do hereby declare the nature of this Invention
to be as follows, that is say :-
This Invention has for its object to improve the construction of holders or lamps
for burning paraffin wax or similar materials to serve as night lights or for other
illuminating purposes.
In carrying out the Invention a cup-like holder of tinned iron or other suitable
metal is provided and can be refilled and used over again repeatedly. The holder is
by preference placed in an outer case or stand when in use, which outer case may be
part of a lamp base, with or without a handle, and be made with a flange or gallery
to support a glass shade or globe, and with passages for admitting a limited supply of
air to the interior of the shade or globe. The globe or shade is by preference made
with a contracted chimney-like top. The shade or globe may be obscured or colored
when it is wished to diminish or modify the light; or a like effect may be obtained
by using a colored or other shade of paper or other suitable material with or without
a glass shade or globe. The holder and outer case are made so as to enclose air to
serve as a non-conducting jacket so that the liquefying of the paraffin may not be
prevented by the cooling of the holder.
The wick is held in a small metal tube which is connected by radial strips at its
bottom to an encircling conducting tube of metal of about inch diameter, made
with notches or holes at its bottom end to allow the liquefied paraffin to pass to the
inside of the tube. The conducting tube projects slightly above the level of the top
of the holder and wick tube, and serves for conducting heat down from the flame to
melt the paraffin or other burning material, With this improved construction the
flame is maintained at one level at the top of the wick tube and the light is not
obscured by descending in proportion as the burning material is consumed and so
getting lower than the sides of the holder.
The paraffin or other burning material may have combined with it any suitable in-
gredient which when burned or heated will evolve disinfecting, hygienic, or fragrant
vapors or odors.

or Wax-like Substances or Compounds.
We, JOHN FYFE, Managing Director of Young's Paraffin Light and Mineral Oil
Company, Limited, of Glasgow, in the County of Lanark, North Britain, and
WILLIAM MCCUTCHON, Manager of the Addiewell Works, West Calder, in the County of
Mid Lothian, North Britain, do hereby declare the nature of this invention and in
what manner the samo is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say :-
This Invention has for its object to improve the construction of holders or lamps for
burning paraffin wax or similar materials to serve as night lights or for other
illuminating purposes.
In carrying out the Invention a cup-like holder of tinned iron or other suitable
metal is provided and can be refilled and used over again repeatedly. The holder
is by preference placed in an outer case or stand when in use, which outer case may
be part of a lamp base with or without a handle, and be made with a flange or gallery
to support a glass shade or globe and with passages for admitting a limited supply of
air to the interior of the shade or globe.
And in order that the said Invention and the manner of performing the same may
he properly understood we hereunto append a sheet of explanatory drawings to be
hereinafter referred to and representing examples of our improved apparatus.
Figure. 1, is a vertical section of a night-light lamp as provided with one modifica-
tion of our improved paraffin holder, shown as unfilled with paraffin the better to
exhibit its constructive details. Figure, 2, is a plan and figure, 3, is a vertical
section of a slightly modified paraffin holder; and figures, 4, and 5, are similar views
of a third modification. In these drawings the same reference letters are used to mark
the same or like parts wherever they are repeated.
The metal base, B, of the lamp figure. I, is made with a gallery, G, to retain the
glass shale, S, and with a cylindrical receptacle, R, into which to put the paraffin
holler. The paraffin holder is in the form of a cup, (, made of tinned iron or other
suitable thin metal. The wick is held in a small central tube, W, which is con-
nected by radial strips, X, at its bottom to an encircling conducting tube, T. of metal
of about inch diameter, made with notches or holes at its bottom ends, and if
necessary at other parts to allow the liquefied paraffin to pass to the inside of the
rube after the paraffin within the tube has been consumed. The conducting tube, T,
extends up to or slightly above the level of the top of the holder, C; and the wick
tube, W, is shorter and does not reach up to that level. With this improved con-
struction the flame is maintained at one level at the top of the wick tube, W, and the a
light is not obscured by descending in proportion as the hurning material is consumed
and so getting lower than the sides of the holder.

page_text: The wick tube, W, may be made by bending a strip of metal so that its longitu-
dinal edges may meet, or so that the edges may be slightly apart from top to bottom
as indicated in figure, 1. Or the wick tube, W, may have the slit between its edges
more or less closed as indicated in figures, 2, to 5, sufficient space being in all cases
left at the bottom of the wick tube to give the liquefied paraffin access to the wick.
The wick tube, W, may be connected to the conducting tube, T, by turning up the
ends of the radial strips, X, as shown in figures, 2, and 3, or by applying solder
to the end of the radial strips, X, left projecting as shown in figures, 4, and 5.
The lamp shade, S, encloses some air round the receptacle, R, to serve as a non-
conducting jacket so that the liquefying of the paraffin may not be prevented by the
external cooling of the holder, C. The air for combination is admitted through
holes, H, in the gallery, or it might be through notches made in the bottom edge of
the shade, S; but these air inlets are made small and fow so that there may not be
so rapid a change of air within the shade as to have a cooling effect on the
holder, C.
The shade, S, is by preference made with a contracted top; and it may be obscured
or colored when it is wished to diminish or modify the light; or a like effect may be
obtained by using a colored or other shade of paper or other suitable material with or
without a glass shade or globe.
The paraffin or other burning material may have combined with it any suitable
ingredient which when burned or heated will evolve disinfecting, hygienic, or fragrant
vapors or odors.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The combination of parts constituting the improved night-light or lamp for
burning solid paraffin or wax-like substances or compounds, substantially as herein-
before described with reference to figure, 1, of the accompanying drawings.
2. An improved holder for solid paraffin or wax-like substances or compounds to
be used as a night-light or for other illuminating purposes, such holder being
provided with a wick tube and a conducting tube substantially as herein before.
