WC, ALEXANDER NEILSON, of Inkermann, near Paisley, in the County of Renfrew,
North Britain, Oil-Works Manager, and JAMES TAYLOR, of Linlithgow Oil Works, in
the County of Linlithgow, North Britain, Engineer, do hereby declare the nature of
this Invention to be as follows, that is to say :-
Our said Invention has for its object to simplify and improve the construction and
action of oil spray or vapor -lamps or burnors of the kind described in the specification
of Patent No. 7939 of 1886, and which are designed for being worked with steam
or compressed air so as to produce oil spray or vapor which is burned for illuminating
or heating purposes.
In carrying out our present Invention we employ a vertical burner body or main jet
tube made with a central bore having a small hole at its bottom end for the admission
of steam or compressed air the bore widening towards the top orifice. The oil supply
pipe is connected to the side of the burner body to the interior of which the oil passes,
through a small hole in a groove in the side of the burner body, its passage
being regulated by a conical valve formed on the end of an adjustable screw
spindle. A horizontal flange or disk is fixed or formed at the top of the burner body
and abovo this disk is a combustion chamber which may be formed or encompassed by
two metal shells of a dome-shaped or other convenient form the outer shell being
fixed to the disk and the inner one either to the slightly projecting nozzle of the
burner body or to the disk.
The steam or compressed air for forcing the oil into spray or vapor is superheated
by passing it through a coil of tubing which may be placed between the two shells
forming the combustion chamber or round the top outlet of these shells, after which it
is led to the small central hole in the bottom end of the burner body up the bore of
which it ascends carrying with it the oil entering at the orifice nearer the top of
burner body. The admission of the steam or compressed air to the bore of the burner
body is also regulated by a conical valve formed on the end of an adjustable screw

page_text: spindle. Additional air to assist the combustion may be admitted through holes made
near the top of the burner body or it may be admitted at the bottom of the inner
shell of the combustion chamber passing in this case through the space between the
two shells. Or the additional air may be admitted through holes in the outer
shell of the combustion chamber and passing up between the two shells may mix with
the burning spray as it issues from the top of the combustion chamber.
The oil and compressed air or steam, may, together or separately be led through
superheating tubing instead of only the compressed air or steam as hereinbefore
described, the heated mixture thus formed being subsequently led to the jet orifice at
the top of the burner body.

Improvements in Oil Spray or Vapor Lamps or Burners for Lighting
and Heating.
We, ALEXANDER NEILSON of Inkermann near Paisley, in the County of Renfrew
North Britain, Oil-Works Manager, and JAMES TAYLOR, of Linlithgow Oil Works, in
the County of Linlithgow, North Britain, Engineer, 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 :-
Our said Invention has for its object to simplify and improve the construction and
action of oil spray or vapor lamps or burners of the kind described in the specification
of Patent No. 7939 of 1886, and which are designed for being worked with steam or
compressed air so as to produce oil spray or vapor which is burned for illuminating or
heating purposes.
And in order that our said Invention and the manner of performing the same may
be properly understood we hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing three modifications of our improved lamps.
Figure, 1, on the accompanying sheet of drawings is an elevation of one
modification of our improved oil spray or vapor lamp; and figure, 2, is a
corresponding vertical section. Figures, 3, and 4, are vertical sections of the other
two modifications. In these drawings the same reference numerals are used to mark
the same or like parts wherever they are repeated.
it an
In carrying out our present Invention according to the modification shown in
figures, 1, and 2, we employ a vertical burner body consisting of three parts, a bottom
part, 3, into the top of which is screwed a main jet tube, 4, having screwed
upon
made with a central bore having a
upper outer body piece, 5. The jet tube, 4,
small hole at its bottom end for the admission of steam or compressed air, the bore
widening towards the top orifice, 6. The oil supply pipe, 7, which extends up from a
tank or receiver, 8, is connected to the upper body piece, 5, at one side the oil passing
to the interior of the jet tube, 4, through a small hole made through from a groove
formed round the jet tube and which forms a communication between the oil supply
pipe, 7, and the hole. The admission of the oil is regulated by a conical valve formed
on the inner end of a spindle, 9, which entering through a stuffing box is screwed into
a part formed on the body piece, 5. The valve spindle, 9, is turned by means of a hand
wheel, 10, fixed on it. A similar screw spindle, 11, with a hand wheel, 12, and which
enters through a stuffing box into the lower body piece, 3, has a conical valve
point on its inner end for regulating the passage of the steam or compressed air into
the bottom end of the jet tube, 4.
A horizontal or slightly dished flange or disk, 13, is screwed upon the upper end of
the jet tube, 4, and above this disk there is a combustion chamber, 14, formed or

page_text: encompassed by two metal shells, 15, 16, the inner one, 15, being of an approximately
globular form, and the outer one, 16, dome-shaped. The inner shell, 15, is supported
by legs with its bottom open end raised a little above the disk, 13, and with its upper
end extending up into an opening in the outer shell, 16. This outer shell, 16, rests
by the edge of its lower cylindrical part upon the disk, 13, and within a retaining flange
formed on that disk and holes are formed round the upper part of the shell, 16, to
admit air, which air being by the action of the burning jet of spray or vapor
drawn between the outer and inner shells, 16, 15, becomes heated on its way to the
flame.
The steam or compressed air for forcing the oil into spray or vapor is superheated by
passing it through a coil, 17, of tubing which is placed so as to encompass the flame
as it issues from the top of the shells, 16, 15. One end of the tubing, 17, is connected
to a supply pipe, 18, (which for convenience is connected by a blind coupling, 19,
to the lower body piece, 3,) and the other end is connected to the lower body
piece, 3. The steam or compressed air superheated by passing through the coil, 17,
entering the bottom of the jet tube, 4, with great velocity which increases with the
gradual widening of the tube acts on the oil which enters through the lateral hole in
the jet tube and very forcibly projects it in the form of spray or vapor outwards
through the combustion chamber, 14, so that it issues thence in the form of a large
and brilliantly illuminating flame.
In the modification shown in figure, 3, the inner shell, 15, is cylindrical and rests
by its bottom edge upon the disk, 13, and a space is left between its upper open end
and the opening in the outer shell, 16. Additional air to assist combustion is in this
modification admitted through holes, 20, in the lower cylindrical part of the outer
shell, 16, and passing up between the two shells, 15, 16, mixes with the burning spray
as it issues from the top of the inner shell, 15. A drip cock, 21, is attached to the
inlet end of the coil, 17, of tubing so as to permit of the removal of any water of
condensation which may gather in the coil.
In the modification shown in figure, 4, the inner shell, 15, is fixed to the upper end
of the main jet tube, 4, of the burner body which in this modification projects
slightly through the centre of the disk, 13. The air to assist combustion passes to
the combustion chamber, 14, through holes, 22, in the upper end of the jet tube, 4,
being admitted to these holes through slots the outer shell, 16. The coil, 17, for
superheating the steam is in this modification placed between the two shells, 16, 15,
forming the combustion chamber, 14.
The oil and compressed air or steam may, together or separately, be led through
superheating tubing instead of only the compressed air or steam as hereinbefore described,
the heated mixture thus formed being subsequently led to the jet orifice at the top of
the burner body.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. An oil spray or vapor lamp in which are combined a jet tube with a bore
gradually enlarging from its inner end to its outer orifice, a supply inlet and valve for
steam or compressed air at the bottom of the jet tube bore, a supply inlet and valve
for oil at the side and between the inner and outer ends of the jet tube bore, a
combustion chamber in the inner of two shells, with holes to admit air between the
shells and access for the air so admitted at the inner end of the inner shell into the
inner chamber, and a coil of tubing for superheating the steam or compressed air such
coil being placed in a position to encompass the flame issuing from the combustion
chamber, the said parts being arranged and combined together substantially as and for
the purposes herein before described.
2. The modification of oil spray or vapor lamp shown in figure, 3, of the
accompanying drawings having in combination with other parts a jet tube with a bore
gradually enlarging from its inner end to its outer orifice, a supply inlet and valve
for steam or compressed air at the bottom of the jet tube bore and a supply inlet and

page_text: valve for oil at the side and between the inner and outer ends of the jet tube bore,
substantially as hereinbefore described.
3. The modification of oil spray or vapor lamp shown in figure, 4, of the
accompanying drawings having in combination with other parts a jet tube with a bore
gradually enlarging from its inner end to its outer orifice, a supply inlet and valve
for steam or compressed air at the bottom of the jet tube bore and a supply inlet and
valve for oil at the side and between the inner and outer ends of the jet tube bore,
substantially as hereinbefore described.
