PROVISIONAL SPECIFICATION.
Improvements in Lamps for Burning Mineral Wax or like Solid
Hydro-carbons.
DOUGALD BALLARDIE, 70, York Street, in the City and County of Glasgow,
Lamp Manufacturer, do hereby declare the nature of this invention to be as
follows:-
A rod or band of copper or other good conducting metal formed into a spiral to be
placed in the lamp container or vessel for holding the wax.
The upper end of the rod or spiral to be enclosed in a small tube, which projects
through and is attached to the cover or top of the container or vessel. The part
of tube projecting admits of a second rod or band being inserted in it, which
rod or band may be bent or shaped to project over the flame of the lamp while
burning. The heat from the flame being conducted through the second rod or
band to the first or spiral rod or band in the container or vessel, will melt the
wax surrounding the rod or band, and thereby supply the wick of the lamp with
liquid wax.

DOUGALD BALLARDIE, Lamp Maker, 70, York Street, Glasgow, 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:-
A rod or band of copper or other good conducting metal is formed into a spiral
to be placed in the lamp container or vessel for holding the wax.

The upper
and is attached to the cover or top of the container or vessel. The part of the
tube projecting admits of a second rod or band being inserted in it, which rod or
band may be bent or shaped to project over the flame of the lamp while burning.
The heat from the flame being conducted through the second rod or band to
the first or spiral rod or band in the container or vessel will melt the wax sur-
rounding the rod or band and thereby supply the wick of the lamp with liquid
wax.

page_text: And in order that the nature and novelty of my said invention, and the mode
and means of putting the same into effect or practice, may be properly under-
stood I shall now proceed to describe the several figures on the sheet of drawings
which I have hereunto appended for that purpose, the same reference letters
indicating the same or equivalent in all figures where shown.
Figure 1 is an elevation, and Figure 2 is a vertical section showing the posi-
tion of the spiral band or rod and the fittings connected therewith.
Letters A A A represent the spiral band or rod which at A¹ is bent upwards and
attached to the lower part of the small tube B. The second rod or band C may
be inserted in the tube until the lower end of it rests on the top of the rod or
band A thus forming a connection forconducting the heat which is gathered from
the flame of the lamp D, Fig. 1 into the container of vessel.
The small tube B is attached to the cover or top of the container or vessel at E.
The rod or band C where bent over the flame at C₁ may be formed into a ring
or helix, open so that the products of combustion may pass through.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
An arrangement for conveying the heat from the flame of a lamp into the con-
tainer or vessel holding the solid hydro-carbon or wax in such a manner that the
solid hydro-carbon or wax will all be liquefied and thereby supply the wick with
the wax that is at the greatest distance from the wick as well as with that which
is near it.
