Improvements in Spray Lamps.
We, THE LUCIGEN LIGHT COMPANY Limited, of Pago Street, Westminster, in the
County of Middlesex, and GEORGE GERRARD, of The Lucigen Light Company Limited,
aforesaid, Foreman Engineer, do hereby declare the nature of this invention to be as
follows
In what is known as the Lucigen lamp and other lamps of spray kind, oil under
pressure is discharged from a small orifice at the apex of a cone situated within a
hollow conical nozzle which is supplied with air under pressure; the issuing stream.
of oil becomes subdivided into spray by the current of air and mingles therewith.
The mixture issues from the nozzle into a cylindrical casing or combustion chamber,
and being ignited gives a powerful flame.
This invention relates to the construction of such a burner in a simple and substantial
manner, with means of adjusting the nozzle. The body of the burner is a cylindrical
socket which is screwed on the oil supply pipe and which has the inner or oil cone
screwed into a horizontal partition that crosses the socket about midway. The air
supply pipe is screwed into the side of the socket above this partition delivering the
air into the annular space within the socket surrounding the inner cone. The outer
cone or nozzle is screwed into the mouth of the socket; by screwing it more or less
in, the space between the two cones can be delicately adjusted, and the nozzle can be
secured in position by a lock nut or otherwise.
The nozzle projects up into the combustion chamber through its base which has a
central circular opening larger than the nozzle, so that there is an annular passage
through the base, freely admitting air to the combustion chamber, rendering the
combustion inore complete, and enhancing the power of the flame.

COMPLETE SPECIFICATION.
Improvements in Spray Lamps,
We, THE LUCIGEN LIGHT COMPANY Limited of Page Street Westminster in the
County of London and GEORGE GERRARD of The Lucigen Light Company Limited
aforesaid 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:
In what is known as the Lucigen lamp and other lamps of spray kind, oil under
pressure is discharged from a small orifice at the apex of a cone situated within
a hollow conical nozzle which is supplied with air under pressure; the issuing stream
of oil becomes subdivided into spray by the current of air and mingles therewith.
The mixture issues from the nozzle into a cylindrical casing or combustion chamber
and being ignited gives a powerful flame.
This invention relates to the construction of such a burner in a simple and substantial
manner, with means of adjusting the nozzle, as will be described with reference to
the accompanying drawing which is a vertical section. The body of the burner is
a cylindrical socket B which is screwed on the oil supply pipe O and which has
the inner or oil cone D screwed into a horizontal partition that crosses the socket
about midway. The air supply pipe is screwed into the side of the socket B above
this partition, delivering the air into the annular space within the socket B
surrounding the inner cone D. The outer cone or nozzle E is screwed into the

page_text: mouth of the socket B; by screwing it more or less in, the space between the two
cones can be delicately adjusted, and the nozzle can be secured in position by a lock
nute or otherwise.
The nozzle L projects up into the combustion chamber F through its base which
has a central circular opening larger than the nozzle, so that there is an annular
passage G through the base freely admitting air to the combustion chamber, rendering
the combustion more complete, and enhancing the power of the flame. When it is
desired to heat the air supplied at A, the air pipe is formed into a coil K
surrounding the upper part of the cylinder F and has a descending branch M to
the socket B.
When the lamp is in action, the air under pressure which may be heated by the
contact of the coil K with the hot cylinder F, enters the annular space C within the
socket B and issues as an annular jet around the cone D. Oil being also supplied
under pressure issues through the orifice of D and becomes subdivided into spray by
the action of the surrounding air jet.
The mixed air and oil spray issuing through the orifice L at the top of the nipple E
and receiving a farther supply of air entering by the openings G and deflected towards
it by the lip H, is ignited and heats the cylinder F from the top of which there
issues a high and luminous flame. The lip H is so formed as to furnish behind a
trough or gutter which receives such oil of condensation as may trickle down the
interior of F.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is
In a spray lamp, the combination of the socket B, the externally coned oil nozzle, D,
the internally coned adjustable nipple E the combustion cylinder F with its air
inlets G and deflecting lip H, and the pipes A and O supplying respectively air
and oil under pressure, with or without the air heating coil K, substantially as
described.
