both of Inkermann in the County of Renfrew, North Britain, do hereby declare
the nature of this Invention to be as follows, that is to say :-
Our said Invention has for its object to improve the construction and action of
lamps of the kind in which oil is burned for illuminating purposes, in the form of
spray or vapor. Our improved lamps are designed for being worked with steam
but compressed air may be substituted for the steam if thought desirable in
any case.

In carrying out our Invention we employ a vertical burner body having the oil
supply pipe connected to the bottom of it. Above the oil inlet the burner body is
made with an enlargement to which is connected a pipe supplying the steam, and
at a higher point there is another enlargement into which air is admitted. The oil
inlet communicates with an internal tube formed with a conical nozzle at its upper
end the position of which is at the steam-inlet enlargement; and within this oil
nozzle there is an adjustable spindle with a conical end to serve for regulating the
passage this spindle being by preference made with a needle point passing through
the nozzle orifice. Above the oil nozzle there is an internal burner tube with its
bottom end made concave or conical and the steam enters between it and the oil
nozzle which is adjustable for regulating the size of the passage. At the part where
the internal burner tube passes through the air-inlet enlargement there are holes in
its sides for the entrance of the air into the tube. At the top of the internal burner
tube the burner body has formed or fixed on it a slightly dished or concave flange
or disk; and at a small distance above this disk there is a globe forming a combus-
tion chamber. This globe may consist of a single metal shell; but it is by preference
made with two shells or in the form of a globular coil of tubing, and the air passes
through it for the purpose of being heated, on its way to the air-inlet enlargement
of the burner body. The openings at the bottom and top of the globe require to
be suitably proportioned and the top opening should be of about double the area of
the bottom opening. In order to get the best results the steam employed is super-
heated, being led through a vessel fixed immediately over the globe and passing
thence to the steam-inlet of the burner body. The steam superheating vessel is by
preference made of a vertically elongated form, with its lower end conical; and the

page_text: main flame of the lamp envelopes it and is enlarged by it. The superheating vessel
may be made in the form of a coil of tubing; or when dry steam of high pressure
is available the superheating of it may be dispensed with.
The oil may be supplied with more or less of a head, the action of the steam if of
sufficient pressure will however draw it up from a lower level if required.

We, ALEXANDER NEILSON, Oil-Works Manager, and JAMES TAYLOR, Engineer,
both of Inkermann, in the County of Renfrew, North Britain, 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 improve the construction and action of
lamps of the kind in which oil is burned, for illuminating purposes, in the form of
spray.or vapor. Our improved lamps are designed for being worked with steam
but compressed air may be substituted for the steam if thought desirable in
any case.
In carrying out our Invention we employ a vertical burner body having the oil
supply pipe connected to the bottom of it. Above the oil inlet the burner body is
made with an enlargement to which is connected a pipe supplying the steam, and
at a higher point there is another enlargement by which air is admitted. At the
top of the burner body there is a slightly dished or concave flange or disk; and at
á small distance above this disk there is a globe forming a combustion chamber.
This globe may consist of a single metal shell; but it is by preference made with
two shells or in the form of a globular coil of tubing, and the air passes through it
for the purpose of being heated on its way to the air-inlet enlargement of the
burner body. In order to get the best results the steam employed is superheated,
being led through & vessel or through a coil of piping fixed immediately over the
globe and passing thence to the steam inlet of the burner body; but when dry
steam of high pressure is available the special superheating of it may be dispensed
with.

"
The oil may be supplied with more or less of a head, the action of the steam, if
of sufficient pressure, will however draw it, up from a lower level if required.
And in order that our said Invention and the manner of performing the
same may be properly understood we hereunto append two sheets of explanatory
drawings to be hereinafter referred to in particularly.describing our improvements.

page_text: Figure, 1, on sheet, 1, of the accompanying drawings is an elevation of our oil
spray or vapor lamp. Figure, 2, on sheet, 2, is an enlarged vertical section of the
burner body with one modification of the globe. Figure, 3, is an elevation
showing a second modification of the globe with apparatus for superheating the
steam; and figure, 4, is a section of a third modification of the globe. In these
drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
In figure, 1, the lamp is shown as supported upon a closed tank or vessel, 5,
which contains the oil to be used in the lamp, and from which the oil is drawn up
through a pipe, 6, dipping down nearly to the bottom of the tank. The oil supply
pipe, 6, is connected to the burner body, 7, of the lamp close to the bottom of that
body which is fixed upon a plate, 8, resting by legs, 9, upon the top of the tank, 5.
The oil inlet into the burner body, 7, communicates with an internal tube, 10,
(figure 2) formed with a conical nozzle, 11, at its upper end the position of which
nozzle, 11, is at an enlargement, 12, formed in the body, 7, and having in it the
steam inlet, the steam entering by a lateral pipe, 13. Within the oil nozzle, 11,
there is an adjustable spindle, 14, by preference made as shown with a needle
point passing through the nozzle orifice, this spindle passing out through a stuffing
box and having a handwheel, 15, fixed at its bottom end. Above the oil nozzle, 11,
there is an internal burner tube, 16, with its bottom end made concave or conical
as shown; and the steam enters between it and the oil nozzle, 11, which is
adjustable for regulating the size of the annular passage from the enlargement, 12,
up between the nozzle and the conical mouth at the bottom of the inner burner
tube, 16. The various parts of the burner body, 7, and the internal tubes, 10,
and 16, are connected by a screw coupling, 17, and other screwed parts, the nozzle
tube, 10, being screwed into the lower body part, 7, and having the upper body
part, 7, connected to it by the coupling, 17, the adjusting of which determines the
position of the nozzle, 11, relatively to the bottom of the inner burner tube, 16.
This inner burner tube, 16, the bore of which is of gradually increasing size from
its bottom upwards, passes through an upper enlargement, 18, in the upper part,
of the burner body, 7, into which air enters by a side inlet, 19, and from this
enlargement the air enters the inner burner tube, 16, through several apertures, 20,
being drawn in by the upward current of steam through the tube. At the top of
the burner body, 7, and inner burner tube, 16, there is a disk, 21; and at a small
distance above this disk there is a globe, 22, forming a combustion chamber. This
globe, 22, as shown in figures, 1, and 2, is made of a coil of metal tubing and serves
for heating the air which is led into the upper enlargement, 18, of the burner body.
The bottom end, 23, of the coiled tubing forming the globe, 22, is fixed through
the disk, 21, and is open for the entrance of air; whilst the upper end is connected
by a continuation, 24, of the tubing at one side down to the inlet, 19, into the
burner body, 7, the globe being supported by the two ends, 23, 24, of the tubing
forming it. The openings at the bottom and top of the globe, 22, require to be
suitably proportioned, and the top opening should be of about double the area of
the bottom opening.
In the apparatus for superheating the steam shown in figure, 1, the steam
supplied by a pipe, 25, provided with a stop valve, passes up a pipe, 26, to a
vessel, 27, placed above the globe, 22. This vessel, 27, is of a vertically elongated
form with its lower end conical; and the main flame of the lamp envelops it and
is enlarged by it. The steam returns downwards from the superheating vessel, 27,
by a pipe, 28, at the bottom of which there is a small stopcock, 29, for blowing off
water of condensation when starting the lamp; and it proceeds thence by the
pipe, 13, into the lower enlargement, 12, of the burner body, 7. A blind pipe, 30,
symmetrical with the pipe, 13, connects the burner body, 7, to the bottom of the
pipe, 26, up which the steam passes to the superheating vessel, 27, and helps along
with the pipe, 13, to support the side pipes, 26, 28, and superheating vessel, 27.
In figure, 3, the superheating vessel is shown as in the form of a coiled pipe;
or it might 'e made in any other suitable form. In the same figure is also shown

page_text: •
a modification of the combined globe and air heater formed by two shells, an inner
globular one indicated by dotted lines and an outer shell, 31, having its lower part
cylindrical and resting upon the disk, 21, at the top of the burner body. In this
modification air enters at the top between the two shells and whilst a part of it
enters the bottom of the globe along with the jet of oil, vapor, or spray steam and
air, another part is led by the pipe, 24, into the upper enlargement, 18, in the
burner body, 7. The globular inner shell is supported and adjusted by pins, 32,
, screwed in through the outer shell, 31.
In figure, 4, another form of combined globe and air heater is shown in section.
It consists of an inner globular shell, 22, combined with an outer globular shell, 33,
an air inlet being at one side, whilst the air heated between the shells is led by a
pipe, 24, at the other side to the upper enlargement, 18, of the burner body, 7.
The shells, 22, 33, are supported at a little distance above the disk, 21, by screw
studs, 34, and air has access to the jet between the disk and the shells.
The globe, 22, of coiled tubing shown in figures, 1, and 2, may be used for
superheating the steam and a shell like the one; 31, shown in figure, 3, may be
placed round it to form an air-heating space. We prefer to have the air heated as
⚫herein before described, but this is not essential; and when the air is not heated
the globe (22) may consist of a single metal shell as herein before mentioned.
Our improved lamp may be used for heating as well as for illuminating
purposes.
•
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
:
1—The combination of parts constituting our improved lamp as shown in
figures, 1, and 2, or as modified by what is shown in figures, 3, and 4, of the
accompanying drawings, the several parts being arranged and operating sub-
stantially as herein before described.
2-The improved construction of burner for an oil spray or vapor lamp, such
burner comprising a body having in it a burner tube which at some distance
below the jet orifice at its upper end communicates with an enlargement in the
body into which steam is admitted and up through which a conical nozzle projects
from the oil inlet, the said burner tube also communicating by holes through its
sides with an upper enlargement in the body into which enlargement air is
admitted, all substantially as hereinbefore described.
