BUYISIONAL DIMITTUATION.
Improvements in and Connected with Oil Spray Lamps for Lighting
and Heating Purposes.
I, GEORGE ROSE of 3 Avenue Place Springburn Glasgow, Lanarkshire, Engineer,
do hereby declare the nature of this invention to be as follows:-
My said invention has for its object to improve the construction and arrangement
of the parts of spray lamps for burning oil in the form of spray for lighting and
heating purposes.
My improvements are applicable to that class of spray lamps wherein steam or air
under pressure is used to spray the oil. Under this invention the lamp may consist
of a base tank or reservoir for containing the oil to be burned the oil being forced
to the burner by the action of compressed air in any well known manner or the
oil may be supplied to the lamp by gravitation or otherwise. For the support of the
burner I erect a stand tube or pipe of novel construction, this stand tube which is
or may be screwed or otherwise fixed into the oil tank has inserted in its lower end
a stuffing or solid piece and likewise at its upper end another stuffing or solid piece,
through these stuffing pieces holes are bored, the oil entering into and filling up the
stand tube through the hole at its lower end and passing out to the burner through
the hole or passage at its upper end. Inserted in the inside of the stand tube is
another tube of smaller diameter into which the steam or compressed air is led, this
tube is screwed into the aforesaid stuffing pieces at each end of the stand tube and
communicates by channels bored therein with the steam or compressed air supply
pipe on the one hand and the pipe passing to the burner on the other hand. In
some cases with steam lamps having the oil forced up to the burner when instantaneous
lighting is required I insert a second tube in the inside of the stand tube this tube
being for the passage of some of the compressed air from the upper part of the
oil tank to the burner. Instead of making the stand tube proper to serve as an oil
tube I may insert a separate pipe within the stand tube for the oil.
By this improved construction of stand tube compactness is obtained with the
further advantage of heating the oil on its passage to the burner.
A further improvement consists in a novel construction of burner and of steam or
compressed air superheating chamber. The burner as constructed under this
invention consists under one arrangement of a hollow chamber divided into two
compartments by a partition, into the lower compartment the steam or compressed
air is led, from thence it passes by a branch into a hollow cylindrical, conical or
other, shaped annular vessel which is preferably tapered conewise at top and which
surrounds and encloses the burner nipple. In this annular chamber which may have
screw plugs for cleaning the steam or air is superheated by the heat of the flame,
the superheated steam or air passing therefrom by a branch, provided with a blow off
cock and a gauze filter to prevent grit or scale passing to the burner, down to the
top compartment of the hollow chamber from whence it passes up through the
burner nipple. This burner nipple which is of cone shape at top is screwed into
the top of or may be so formed as to constitute the cover of the hollow steam or
air chamber. On the outside of the cone shaped nipple a cap preferably of nozzle
shape is or may be screwed, this cap is or may be provided with a hole or series of
holes preferably round its base part through which oil passes to the burner nipple,
the oil which may be supplied by gravitation or otherwise is led or forced into the
inside of the annular superheating vessel at the bottom of which it lies, being thence
drawn or sucked up through said hole or holes in the cap and sprayed by the jet of
steam or air. A draw off cock may be provided at the bottom of the annular
superheating vessel to draw off any, superfluous oil-In some cases another hole or

page_text: series of holes is made in the cap at a little distance above the first hole or series of
holes for the purpose of allowing air to pass inside.
Air to support combustion is supplied through air induction tubes passing up
through the bottom or through the sides of the annular superheating vessel or
through both.
Under another arrangement the hollow chamber constituting the base of the burner
instead of being divided into two compartments as aforesaid may consist of a single
compartment the lower end being made solid and screwed into the top of the stand
tube of the lamp or being made to form the, or a part of the stuffing piece herein-
before described as being inserted into the top of said stand tube. In this case the
steam or air passes up through the tube in the inside of the stand tube and if desired
through a channel formed in the lower solid end of said hollow chamber from thence
it passes by a branch up into a superheating chamber placed above the burner, this
superheating chamber is preferably made of annular cylindrical shape being formed
of a short inner pipe fixed at its upper and under ends into contracted parts of an
outer enclosing pipe. This chamber which may be provided with cleaning screws
has or may have a coil tube for further superheating the air or steam placed above
and in connection with its upper end. Instead of forming the chamber of annular
form as described the chamber may consist of one or a series of rings of a
rectangular shape in plan having or not screw plugs at the elbows or joints, the rings
if two or more be used being connected together by straight vertical pipes or tubes.
Sometimes the rings instead of being rectangular in plan as described may be circular
and formed in two halves bolted together or they may be split rings of C shape in
plan. From the superheating chamber or from the coil which may surmount it, the
steam or air passes downwards to the hollow chamber constituting the base of the
burner and thence to the burner nipple in the same manner as described under my
prior modification. Instead of having a cap to surround the burner nipple under this
arrangement the cap may be dispensed with, the oil being led up the stand tube,
preferably through a channel in the stuffing piece at its upper end, into and filling a
circular or other shaped cup surrounding the nipple from whence it is sucked up by
the inductive action of the air or steain jet. As a provision against extinguishing
of the flame from the presence of water in the oil or from other cause I may
arrango in the inside of this cup a piece of asbestos or other suitable substance or
an asbestos or other wick of a shape similar to that of the cup. By this means in
case of the main flame being extinguished it is immediately relighted by the
permament flame of the wick. The wick is further by this arrangement kept always
supplied with oil.
.
Under a further modification the hollow chamber may have its under side formed
by a screw plug and through this screw plug a small hole is drilled or bored or other-
wise formed a blow off cock being screw fitted into the end of the hole. In this
arrangement the burner nipple is or may be screwed into or form the top or cover
of the hollow chamber. Screwed on the upper end of the chamber or on a collar on
the burner is a combustion box which may be of the cylindrical form described
under my prior application No. 359 of 1888. The oil is admitted to the bottom of
this combustion box and there lies, it being sucked up by the inductive action of the
air or steam jet issuing from the burner nipple. An asbestos wick as hereinbefore
described may be also used under this arrangement it being placed in the bottom of
the combustion box or within a little cup or recess formed around the top of the
hollow chamber and upon which the oil drops. Small holes are or may be inale in
the sides of the hollow chamber for the oil to trickle through, by this means the wick
is kept constantly saturated. The steam or air is superheated by being made to pass
through a coil surrounding or placed above the top of the combustion box.
heavy hydrocarbons are burned with my improved arrangements of lanip such
When
heavy hydro-carbons would be preferably first heated by being made to pass through
a coil surrounding the combustion box or annular steam superheating chamber.
In applying the lamp or burner for heating purposes I so arrange it that the
flame is projected into the furnace or heating chamber in a horizontal or inclined

page_text: direction above the bottom or hearth. When so arranged the oil may be led into
the cap surrounding the burner nipple.
The burner and superheating chamber is or may be surrounded by a casing to
prevent chilling by cold air.
Although I have described my arrangements of superheating chamber as being
used for superheating steam or air it is to be understood that the said superheating
chamber can be used for converting water into steam to spray the oil and thus
constitute a self generating steam lamp. When the chamber is used for this
purpose the water to supply said chamber is or may be contained within a jacket.
surrounding the oil tank or two separate semicircular tanks can be made to contain
oil and water respectively these tanks being bolted together, in either case the oil
and the water would be forced to the burner & steam generating chamber by air
pumped into the tank or tanks as the case may be from a small force pump suitably
connected or by other means. The water may be supplied from the main or by
gravitation if so desired.
In some cases I may introduce a jet of air from the compressed air pipe into the
superheating vessel or coil and pass the same along with the superheated steam to
the burner.

COMPLETE SPECIFICATION.
Improvements in and Connected with Oil Spray Lamps for Lighting
and Heating Purposes.
I, GEORGE ROSE formerly of No. 3 Avenue Place, Springburn now of 70 Wellington
Street, Glasgow, 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:
-
My said invention has for its object to improve the construction and arrangement
of the parts of lamps for burning oil in the form of spray for lighting and heating
purposes. My improvement whilst generally applicable to the class of lamps
wherein steam or air under pressure is used to spray the oil are especially
applicable to that class of self generating steam lamps described in my prior
Specification No. 1151788.
And in order that my said invention may be properly understood, I have hereunto
appended two explanatory sheets of drawings.
On the drawings the reference letters wherever repeated indicate similar or
like parts.
Fig. 1 of the drawings, represents, in side elevation, and fig. 2 in plan, one form
of my improved lamp. Fig. 3 is a sectional elevation and fig." a plan of the burner
of same. Figs. 5, 6, 7, 8, 9, 10, 11 and 12 represent in elevation and plan different
forins of steam generating or steam or air superheating coils and chambers. Figs. 13
and 18 represent, in vertical section, stand pipes for supporting the burner of the
lamp. Figs. 14 and 15 represent in side elevation and plan respectively a three way
cock arrangement for controlling the oil, water and air supply. Figs. 16, 17, 19,
20, 21, 22 and 23 represent in section, different forms of burner and steam
generating or superheating chamber. Fig. 24 represents in side elevation an oil and
water tank.
As shown at figs. 1 and 2, the lamp as constructed in accordance with this invention
consists of a base tank or reservoir A, for containing the oil to be burned, upon which
is mounted a stand pipe or tube B of novel construction. This stand pipe which is
screwed or fitted into the oil tank A, has at its lower end a stuffing or solid piece C
(see fig. 13) and also at its upper end another stuffing or solid piece D; through

page_text: .
the piece C, holes a, b are bored and through the piece D a hole or channel cis
bored. The stand pipe is preferably built up in the manner shown at fig. 13. The
oil to be burned passes from the tank A, up the tube and thence through the
channels e and a into the stand tube B which it fills; from the stand tube the oil
passes, under this method of construction, through the branch of a tee piece,
supporting the stuffing piece D, to the burner E (see fig. 1). Inserted in the inside
of the stand tube B is another tube F of smaller diameter into which the steam or
water to be converted into steam or compressed air is led: This tube is screwed
into the aforesaid stuffing pieces C, D, at each end of the stand tube and com-
municates by the channel b, on the one hand, with the steam, water or air supply,
and, on the otlier hand, by the channel c with the pipe passing to the burner. In the
lamp shown at figs. 1 and 2, water from a small tank G which is affixed to the oil
tank A and has a pressure gauge h and pump i on it, passes by the tube connection j
(figs. 1, 2, and 13) to the tube F and so to the steam generating coil or chamber,
which surmounts the burner, and wherein it is converted into steam to spray the oil
in the manner described in my prior Specification No. 1151788. In some cases 1 may
insert a second tube H within the stand tube B as shown at fig. 18 this tube is for
the passage to the burner, for a short period when starting the lamp, of some of the
compressed air from the upper part or air space of the oil tank A, or it may be the
water tank G when this is used, for the purpose of spraying the oil and so enabling
the lamp to be lit instantly, and thus, when the lamp is worked as a self generating
steam lamp, to generate sufficient steam to enable the flame to be maintained; or,
when the lamp is worked as a steam lamp, to superheat the steam. This method of
constructing the stand pipe shewn in this figure, as will be seen, is slightly different
from that at fig. 13. The air from the upper part of the oil tank A is led by the
pipe connection through the channel in the stuffing piece C to the tube H, from
thence it passes by the channel to the burner of the lamp. The oil in this case
instead of passing from the stand pipe B to the burner, through the branch g of a
tee piece, as shown at fig. 13, may pass directly up through the channel 7 and
thence to the burner-Instead of making the stand pipe, proper to serve as an oil
tube may insert another pipe within the stand tube for the oil. With the improved
constructions of stand tube compactness is obtained with the further advantage
that when the lamp is worked with steam the oil is heated on its passage to the
burner.
Another improvement consists in a novel construction of burner and of steam or
compressed air superheating chamber. The burner as constructed under this
invention consists under one arrangement as shown in vertical section at fig. 22
(sheet 2) of a hollow chamber I divided into two compartments 11, 12 by a partition 13
into the lower compartment the steam or compressed air or water, as the case may
be, is led, from thence it passes by a branch J into a hollow cylindrical, conical, or
other shaped annular vessel. In the drawings a conical vessel or chamber K is
shown. This chamber K which surrounds and encloses the burner nipple, L, has its
lower end bolted or rivetted to a base plate o screwed on top of the burner nipple as
shown. In this annular chamber which may have screw plugs fitted in it for
cleaning, the steam, or air is superheated or the water is evaporated as the case may
be by the beat of the flame; the superheated steam or air passes therefrom by a
branch K, provided with a blow off cock m down to the top compartment I¹ of the
hollow ‘chamber I from whence it passes up through the burner nipple L. This
burner nipple L which is of cone shape at top, as shewn, is screwed into the top
of or may be so formed as to constitute the cover of the hollow steam or air
chamber On the outside of the cone shaped nipple a cap M preferably of nozzle
shape as shown
screwed, this cap is or may be provided with a single hole or a
series of holes m¹ preferably round its base part, through which oil
passes to the
burner nipple; the oil, which may be supplied by gravitation or otherwise, is led, or
forced, through the pipe m² into the inside of the annular superheating vessel, at the
bottom of which it lies, being thence drawn or sucked up through the holes, m², in

page_text: the cap, m, and sprayed by the jet of steam or air.
If desired a draw-off cock may
be provided at the bottom of the annular superheating vessel to draw off any super-
fluous oil. In some cases another hole or a series of holes m³ may be made in the
cap at a little distance above the first hole or series of holes m' for the purpose of
allowing air to pass inside and become admixed with the oil jet. Air to support
combustion is supplied through two or more air induction tubes n passing up
through the bottom or base plate, O, of the chamber K, or through its sides, or
through both.
Under another arrangement the hollow chamber I, constituting the base of the
burner instead of being divided into two compartments I, I' as aforesaid, may consist
of a single compartment as shown in section at figs. 16, 17, and 21. In this case the
lower end of the chamber 1 may be made solid and be screwed into the top of the
stand tube of the lamp, as shown at fig. 21; or it may be made to form the or a part
of the solid piece D, herein before described with reference to figs. 13 & 18 as being
inserted into the top of the stand tube B. With this arrangement the steam air or
water as the case may be passes up through the tube, F, in the inside of the stand
tube B and through a channel e formed in the lower solid end of the hollow chamber I
from thence it passes, by the branch J, up into a superheating chamber, P, placed
above the burner, this chamber, P, is of somewhat similar construction to the
chamber, K, fig. 22, except that it is of cylindrical shape being formed of a short
inner pipe fixed at its upper and lower ends into contracted parts of an outer
enclosing pipe. This chamber which may be provided with cleaning screws P₁, has
or may have a coil tubo p for further superheating the air or steam, placed above and
in connection with its upper end. Instead of using the form of chamber P herein-
before described, that shown at fig. 23, may be employed, in this case the chamber P
is of ring shape and of oblong cross section. A small coil pipe or boiler P³, as
shown, may be fitted below the chamber P as well as the superheating coil, p, above.
From the superheating coil p under, either, the arrangement at fig. 17 or that at
fig. 18 the superheated steam or air passes downwards to the hollow chamber I
constituting the base of the burner and thence to the burner nipple L, in the same
manner as described under my prior arrangement at fig. 22. Instead of having a
cap, however, to surround the burner nipple, under this arrangement, the cap may be
dispensed with the oil being led up the stand tube, B, through the channel into and
filling up a circular or other shaped cup or well, Q, surrounding the nipple L which
projects up through its centre. The cup or well, Q, may be screwed on to the top of
the nipple, I, as shown at fig. 17 or it may be screwed into and form the cover of
the hollow chamber, I, as shown at fig. 16. In the latter case the nipple L may be
screwed into the centre of the cup Q, as shown. The oil in the cup Q is sucked
up and sprayed by the inductive action of the air or steam jet issuing from the
nipple.
g
As a provision against the extinguishing of the flame from the presence of water
in the oil or from other cause, I may arrange in the inside of the cup Q an asbestos
or other wick Q¹ (see fig. 16) of a circular shape, similar to that of the cup. By
this arrangement should the main flame be extinguished from any cause it is
immediately relighted by the permanent flame of the wick. As the oil is continually
flowing into the cup through the inlet m² the wick is always saturated with oil.
Instead of having an asbestos wick as herein before described loose asbestos or other
suitable material may be placed in the cup to serve as a wick. To keep the wick in
place an inner concentric rim, Q, or equivalent may be cast in one piece with the
cup. This rim, Q', may have a number of holes, Q, in it through which the oil
passes to the burner nipple. In the arrangement shown at figs. 19 & 20 there is
screwed on the upper end of the chamber I or on a collar on the burner, I, a
combustion box S, S¹, of the cylindrical form described under my prior patent
No. 359 of 1888. The oil is admitted to the combustion box the bottom of which it
fills. The oil and oleaginous vapour is sucked up and sprayed by the inductive action
of the air or steam jet issuing from the burner nipple, L, in the same manner as
before. An asbestos wick, Q, (fig. 19) may be also used under this arrangement it

page_text: being placed in the bottom of the combustion box or within an annular recess or
trough formed around the top of the hollow chamber I and upon which the oil
drops. Small holes, s, are or may be made in the sides of the hollow chamber, I,
for the oil to trickle through to the burner nipple, L. By having the wick 50
arranged it is kept constantly saturated with oil. The steam or air is superheated by
being made to pass through a coil surrounding or placed above the top of the
combustion box in the same or similar manner to that described in my prior
Specification No. 35988.
When heavy hydro-carbons such as tar oil and the like, are burned with my
improved arrangement of lamp such heavy hydro-carbons would be preferably first.
heated by being passed through a coil such as T (fig. 20) surrounding the combustion
box or annular superheating chamber. The heavy tar oil becoming highly heated
runs down into the combustion box, S, and is there sucked up and sprayed.
The chamber or burner I may have as shown at figs. 3, 19 & 20 a screw plug R
screwed into its underside. Through the plug a small hole is drilled and a cock
fitted therein for blowing off water of condensation or any dirt which may
accumulate in the chamber.
Instead of using an annular chamber as hereinbefore described for superheating
the steam or air or for converting the water into steam, coil pipes of the forms
illustrated at figs. 5, 6, 7 & 8 may be used, or a plain coil, or the coil described in
my prior Specification No. 11517 of 1888 may be employed. The coil shown in
elevation at fig. 5 and in plan at fig. 6 is a double coil, that is to say, it is first
coiled to the top in the turns 1, 2, 3, 4, & 5 then passes down again by the straight
part 5 and is again coiled upwards in the alternate turns 6, 7, 89 & 10 and thence
passes to the straight part 10. The water, air, or steam, as the case may be passes
from the source of supply into the coil at, 1, and after being converted into steam
or superheated therein is led to the burner nipple by the pipe 10°.
In elevation at fig. 7 and in section, on the line - fig. 7, at fig. 8 a different
form of coil is shown, the pipe in this instance is bent in a serpentine form, the
water, air, or steam passing alternately up one bend and down the next until it
eventually escapes to the burner, being converted into steam or superheated, as the
case may be in its passage. Instead of using a bent or serpentine coil pipe, a
chamber cast with serpentine channels therein may be used.
In elevation in fig. 9 and in plan at fig. 10 the split ring arrangement for vapour
generation described under my prior Specification No. 3778 of 1888 is used for
converting water into steam or for superheating steam or air. In this arrangement
the split rings t which are C" shaped (see fig. 10) are placed one above the other
and connected together by short vertical pipe connections . The water or the steam
or air as the case may be, enters the lowermost ring at 2 circulates around it and
passes by the connection t' into the next higher ring, circulates round it and into the
one above and so on until the top one is reached. The superheated steam or air
from which passes out by the pipe 3 and is led downwards to the burner below
the rings.
Instead of having split rings of "C" shape, herein before described, rings formed
in two halves bolted together or cast in one piece, may be used. This arrangement
is illustrated in cross section and in plan at figs. 11 & 12. As will be seen the
rings are made in two halves secured together by studs u¹ or bolts passing right
through both halves may be used. Flanges u² are preferably cast on the halves for
the purpose of enabling them to be fitted more tightly together. The joints are
filled with asbestos or other suitable packing. When these chambers or rings are
used to superheat the steam or air or to generate steam the water in the steam or. air,
as the case may be, enters the ring at circulates right round it and escapes by
the outlet u. A division or partition u shown in dotted lines is preferably cast in
the ring. When employing this arrangement 3 or more rings connected together
in the same manner as the "C" rings fig. 9 are preferably used. Instead of using
rings, squares similar to those described in my prior Specification No. 11:17 of 1888
may be employed. In applying the lamp or burner for heating purposes I so arrange

page_text: it that the flame is projected into the furnace or heating chamber in a horizontal
or inclined direction above the bottom or hearth. When so arranged the oil may be
led into the cap surrounding the burner nipple in the manner shown at fig. 21 and a
burner of that construction is preferably used.
The burner and superheating coil or chamber may be surrounded by a casing, V,
(figs. 1 & 2) to prevent chilling by cold air.
:
When the lamp is being used as a self generating steam lamp, the water and
oil may he contained in two semi-circular tanks V, V, fig. 24, bolted together as
shown.
When it is found advantageous the water for the lamp may be supplied by
gravitation instead of being forced up to the burner by an air pump.
In working with the lamp figs. 1 & 2 oil is allowed to flow from the tank A
up the stand pipe B to the oil cup of the burner, a jet of air from the air space in
the water tank G is then turned on by the three way valve W, shown more
particularly at figs. 14 & 15, this air blast passes up the pipe F (fig. 13) through
the coil shown in dotted lines, fig. 1. to the steam chamber v of the burner I (see
fig. 3) and then to the burner nipple L. The air jet sucks up and sprays the oil
and oil vapour in the oil cup and so enables the lamp to be lit instantaneously.
After the self generating steam coil or chamber has been heated by the air spray
flame to such a temperature as shall convert the water into steam, the air blast
is turned off by the three way cock W and the water supply turned on, when the
lamp works continuously with a steam spray. In the three way cock hgs. 14 & 15,
Wis the water and air outlet, W the air inlet and W³ the water inlet.
In the arrangement shown at fig. 18, the three way cock is not used the air
supply being regulated by the valve K' whilst the water or steam is regulated by
the valve j'.
In some cases I may introduce a jet of compressed air from the pipe H (fig. 18)
into the superheating or steam generating vessel or coil pipe and pass the same
along with the superheated steam to the burner.
If desired the oil tank may be used for the water reservoir and the water tank
for oil and also the tube F of the stand pipe B fig. 13 may be used for oil instead
of water, air or steam, and the tube B may be used therefor.
The several structural details of my improved lamp may be slightly altered without
departing from my invention.
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-
1. In self generating steam spray lamps for lighting and heating purposes, a
stand pipe consisting of an outer tube B and an inner tube F, the one for the passage
