PROVISIONAL SPECIFICATION.
Improvements in and connected with Lamps for Vaporising and
Burning Oil.
We, JAMES HAIG, of 2 Scott's Lane, Port Glasgow, in the County of Renfrew,
North Britain, Mechanic, and WILLIAM SHARP, of 5 Carwood Street, Greenock, in the
same County, Brassfounder, do hereby declare the nature of this invention to be as
follows, that is to say :-
This invention has for its object to construct improved fixed or portable lighting or
illuminating apparatus specially suitable for use out of doors or in workshops, halls, or
other large interiors.
The improved apparatus comprises a bottom plate or dish made with a raised rim,
within which rim there fits easily a cylindrical or slightly coned shell. In the bottom
of the dish and within the shell there are fixed a number of tubes projecting upwards
and serving to admit air through the bottom. Just above the tops of the air-inlet
tubes there are two or more short horizontal burner pipes with closed ends and with
small jet perforations on their upper sides for the issue of the oil vapor, which is
ignited at these burner perforations the flame or flames passing upwards and out at the
top of the shell. The horizontal burner tubes are formed in one piece with or fixed
to a central vertical tube which extends upwards inside of a vertical vaporising
cylinder which is heated by the flame or flames passing up round it. The upper end
of the central tube is open and the oil is led by an inlet pipe into the space between
the central tube and the cylinder and being vaporised by the heat the vapor passes
down the central tube to the burner pipes.
The oil is by preference supplied from a tank or holder placed sufficiently high to
give the requisite pressure to the oil; but any suitable known arrangement may be
used which will cause the oil to be supplied with suitable pressure. The oil supply
pipe is fitted with a main supply cock for shutting off the supply completely, whilst a
finely adjustable needle valve is provided for regulating the passage of the oil into the
vaporiser.
For starting the lamp a little inflammable oil is put into the dish and ignited, and
its flame heats the vaporising cylinder and starts the vaporisation of the oil supplied to
that cylinder.

COMPLETE SPECIFICATION.
Improvements in and connected with Lamps for Vaporising and
Burning Oil.
We, JAMES HAIG, of 2, Scott's Lane, Port Glasgow in the County of Renfrew,
North Britain, Mechanic, and WILLIAM SHARP of 5 Carwood Street, Greenock, in the
same County, Brassfounder 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, that is to say :-
This invention has for its object to construct improved fixed or portable lighting or
illuminating apparatus specially suitable for use out of doors or in workshops, balls, or
other large interiors.
The improved apparatus is shown upon an accompanying sheet of explanatory
drawings, Figure, 1, being a sectional elevation of the principal parts, and Figure, 2,
being a general view drawn to a smaller scale.

page_text: The improved apparatus comprises a bottom plate or dish, A, made with a raised
rim, A 1, within which there fits easily a shell, B, which is shown as narrowing
towards its upper end, but which may be as wide at the top as at the bottom, and of a
circular, or square, or other simple form in horizontal section. Provision is made for
admitting some air at the lower part of the space within the shell, B, the provision
for this purpose shown in the drawing consisting simply of openings, Bi, at the
bottom of the shell, and slits, B2, at a higher level in the sides or corners. Or air
might be admitted from below through tubes fixed in the dish, A, and projecting a
short distance upwards. A little above the air inlets, B 1, there are two (or it might
be more) short horizontal burner pipes, C, with closed outer ends, and with small jet
perforations C1, on their upper sides for the issue of the oil vapor which is ignited at
these burner perforations, the flame or flames passing upwards and out at the top of
the shell, B.
'
.
The horizontal burner tubes, C, are formed in one piece with, or fixed to, a central
vertical tube, D, to the bottom end of which the dish A, is fixed, and which extends
upwards centrally inside of a vertical vaporising cylinder, E, which is heated by the
flame or flames passing up round it. The upper end of the central tube, D, is open,
and the oil is led by an inlet pipe, F, into the space between the central tube, D, and
the cylinder, E, which is otherwise entirely closed, and the oil being vaporised by the
heat the vapor passes down the central tube, D, to the burner pipes, C.
The oil is, by preference, supplied from a tank or holder, G, Figure, 2, placed
sufficiently high to give the requisite pressure to the oil; but any suitable known
arrangement may be used which will cause the oil to be supplied with suitable
pressure. The oil supply pipe, H, is fitted with a regulating stopcock, J, after passing
which stopcock the oil finds its way into the pipe, F, connected to the vaporising
cylinder, E, through a small orifice, K. A needle or wire, L, on the inner end of a
screw spindle, L1, passing through a stuffing box, is arranged so that it can be pushed
into or withdrawn from the perforation, K, to assist in controlling the passage of the
oil, but serving principally for clearing the perforation K, when required. A short
length of tube, M, with a closed bottom end is connected below the part com-
municating with the pipe, F, to serve as a receptacle for any sediment in the oil. The
various parts of the apparatus are screwed together and can be easily separated for
cleaning the internal parts.
For starting the lamp a little inflammable oil is put into the dish, A, and ignited,
and its flame heats the vaporising cylinder, E, and starts the vaporization of the oil
supplied to that cylinder.
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 :-
The combination of parts constituting the improved apparatus for vaporising and
burning oil, substantially as hereinbefore described, and shown in the accompanying.
drawings.
