Improvements in and connected with Lamps for Burning Mineral
or other Oil in the form of Spray, for Lighting, Heating, and
Signalling Purposes.
I, GEORGE ROSE of 70, Wellington Street Glasgow, Lanarkshire, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to that class of spray lamps for heating, lighting and
signalling purposes, wherein compressed air or steam is used to spray the oil; and it
has for its object to simplify and improve the construction and arrangement of the
parts, of lamps of this class.
In spray lamps for lighting, heating and signalling purposes, as constructed under
this invention, the oil from the oil tank or reservoir is led up, or to, a burner of novel
construction, which consists of a hollow body or chamber, in the top of which, is
screwed or otherwise secured, a piece, constituting a spraying nipple, and hollowed
out by preference to a cup or inverted conic shape, for the purpose of preventing any
carbon or other matter, which may be sucked into the vacuum at the spray orifice,
from accumulating and choking said orifice. Through the top or cover of the hollow
chamber a hole is bored for the passage of the compressed air or steam, which enters
the hollow chamber through a lateral branch. To filter the air or steam from scale
or grit, before passing to said outlet hole, 1 may affix thereto, or therein, a small
cylinder or piece of perforated metal, wiro gauze, or equivalent. The oil to be
sprayed and burned is also led through a lateral passage preferably bored through the
top or cover of the hollow chamber, although the oil passage may be bored vertically
up through one side of the hollow chamber. The floor of the hollow chamber may
either be cast solid with the chamber, or it may be constituted by a screw plug or
piece, or its equivalent.
Under a modified construction instead of the burner being made as herein before
described, it may consist of a solid cylindrical or partly cylindrical and partly conical
piece of metal, in which is bored, or formed, in the direction of its length, a channel
or way inceling this channel, preferably at a point near to the outer end of the
burner, is another channel or way bored through the solid metal, preferably at right-
angles to the first or longitudinal channel.
The longitudinal channel, which is for the steam or air, is, by preference, made or
bored from the point of junction between it and the cross, or oil, channel, to the outer
end of the burner, of a slightly larger diameter. The outer end of this burner is also
preferably hollowed out into a cup, or inverted conic, shape.
Surmounting the burner is a combustion box, which is somewhat of the saine con-
struction as that described under my prior patent No. 359 of 1888, and consists of an
outer casing or cylinder, in which is supported concentrically by hangers or equi-
valent, another preferably shorter cylinder. In the annular space formed between
these two cylinders, 1 insert a superbeating coil pipe, one end of which communicates
with the air or steam supply whilst the other end communicates with the burner. In
some cases and especially when the lower end of the onter cylinder of the combustion
box is made tapered so as to be easily fitted on the burner, instead of fitting the super-
heating coil pipe in the annular space between the concentric cylinders, it may occupy
the space between the lower end of the inner cylinder and the top of the burner. At
the point where the superheating coil pipe joins the burner, a small drip tube or
chamber may be fitted, for collecting any condensed water or dirt, this drip chamber
would by preference be provided with a small draw off cock or tap at its lower end.
The oil to support combustion, and the air or steam, as the case may be, to spray
the oil, are each conducted, from their respective sources of supply, to a regulating

page_text: valve or cock of novel construction, this valve or cock consists preferably of a hollow
barrel of cylindrical or other shape, having four openings or ways formed in it, two
on each side; the two on one side constituting respectively the steam or air inlet and
outlet, and the two on the other side, the oil inlet and outlet. In this barrel is fitted
a plug or key, capable of being easily turned by a handle or wheel and which has
bored in it, two elbow shaped channels or ways, which, when the cock or valve is
turned slightly round, opens communication between the oil inlet and outlet and the
air or steam inlet or outlet simultaneously; likewise, when the plug is turned back
or reversed, the air or steam and the oil are both shut off synchronously. For the
nico adjustment of the oil and air or steam supply, I, by preference, fit on the valve or
cock a dial plate, finger or pointer fitted to the key or plug of the valve or cock
indicating thereon the degree to which the valve has been opened or closed. The
ways or channels in the key or plug instead of being elbow shaped, as herein before
described, may be straight and the valve or cock may be otherwise slightly altered to
meet different circumstances which may arise.
The oil and the air or steam from the two way valve or cock, is led by two separate
tubes to the burner, these tubes are, for the sake of compactness, either both enclosed
in a third tube which may constitute the stand pipe, supporting the burner and com-
bustion box, or they may be enclosed the one within the other.
The oil before passing to the burner to be sprayed would preferably have its supply
regulated and controlled by a regulating apparatus, consisting of a hollow box or casing
surmounted by a suitable lid or cover, which latter may, if desired, he provided with
an air valve at top and a draw off cock at bottom. Into the box or casing is led the
oil supply pipe which has at its end an outlet valve or cock of any suitable construc-
tion. The outflow of the oil, through the valve, is regulated and controlled by a float
or ball, which, as it rises and sinks on the surface of the oil contained in the box or
casing, works a lever, rod, arm or equivalent device to open and close the valve or
cock and so regulates and controls the outflow. The oil issuing from this regulating
box or casing is made to pass for the purpose of preventing as far as possible any grit
or dirt passing along with the oil to the burner, by preference, through a small cone
having a hole at its apex, situated in the pipe leading to the burner. A tap or valve
for opening up and cutting off the oil supply is also provided on this pipe.
The oil supply pipe is by preference connected to the burner by a ።
piece; the head of the tee, or one of the branches of the cross piece, being in line with
the oil passage in the burner; the outer branch of the "tea" or "cross" piece is either
left open, or it may be closed by an easily removable screw plug. With this arrange-
ment, the oil passage in the burner can be easily cleaned by passing a wire or rod
down the head of the "tee," or the branch of the cross piece, and into the oil
passage.

From
When my improved lamp is to be used for signalling purposes, I, by preference,
use a hollow cup shaped burner, in which the air or steam nipple is centrally secured,
and communicates with a bollow air or steam chamber forming the base of the burner,
into which the steam or air supply is led by a lateral branch. In this form of burner
the oil is led, from the source of supply, or from the oil regulating apparatus, into an
annular space formed between the lower end of the combustion box and the wall
of the burner cup, either through a channel bored through the side of, or a pipe
secured in, the hollow steam or air chamber, or by a separate branch pipe.
the said annular space the oil trickles through holes formed in the wail, or otherwise,
into the cup and so to the point of the burner nipple. For the purpose of keeping a
light continually burning in the combustion box, during the periods when the oil and
air or steam supply to the burner is cut off, I, by preference, insert in the annular
space, between the wall of the cup and the combustion box, an asbestos or other wick
which will keep alight during the periods, between the flashes, and will on the oil
spray being again turned on instantly relight it. Instead of the burner hereinbefore
described may use a burner similar in construction to that described under. my
prior patent No. 359 of 1888, which consists of a chamber in the centre of which the
oil nipple is secured; the chamber has a small hole at top through which the oil

page_text: nipple projects leaving an annular orifice or opening for the steam or air jet. Under
this invention I cast on or attach to the top of the chamber, a cylindrical piece which
forins between it and the chamber an annular space into which I place an asbestos or
other wick for relighting the spray jet when desired.
When it is desired to turn off the oil and air or steam, or the oil only, so as to put
out or lower the flame when signalling, I prefer, in all cases where the controlling
valve or cock is situated some distance above the ground, or in the case of a vessel,
above the deck, to affix a quadrant or a bell-crank lever or equivalent device to the
handle, key, or spindle of the valve or cock, which can be actuated by chains, wires,
or cords so as to turn the oil or air or steam, as the case may be, on or off, at will. In
some cases, where a hell-crank lever or a quadrant is used, a spring may be so fitted
to one arm or end, as to keep the valve opened or closed whilst a cord, wire, rod or
equivalent is attached to the other end and on being pulled from below closes or opens
the valve.
In some cases for signalling or other purposes a cylindrical casing may be fitted so
as to enclose the combustion box, this casing on being raised, by means of a wire,
rod, chain, cord or equivalent acting on a lever or its equivalent which would catch
on the underside of the casing and lift it up, encloses the light and hides it from view.
When it would be desired to show the light, the pressure would be taken off the
cord, rod, chain, or equivalent and the casing would then fall by its own weight.
The casing, when the light is not far above the ground may, if desired, be lifted up,
to obscure the light, by means of handles secured to it or to rods or their equivalent
attached to its underside.
A wind guard may be fitted to the lamp, being secured in position by a ring
passing round the stand pipe or lower end of the combustion box and being free to
move thereon, and by another ring or equivalent secured to the upper end of the
combustion box and moving freely thereon. From these rings rods or stays, or equivalent,
to hold the guard in position, may project, or the guard may be secured directly to
the rings themselves. A vane may, if desired, be secured to the guard or to the rods
attached to it, to keep the guard always with its back to the wind and so shield the
light.
In many instances, the arrangements which have been described for the steam or
air supply, may be used for the oil supply, and vice versa the oil supply arrangements
be used for the steam or air.
My improved lamp may be used for heating as well as illuminating and signalling
purposes, and when so used in connection with any furnace or arrangement for heating
metals or ores, melting, and other purposes, the flame would by preference be
directed horizontally into the furnace or chamber to bo heated.

COMPLETE SPECIFICATION.
Improvements in and connected with Lamps for Burning Mineral
or other Oil in the form of Spray, for Lighting, Heating, and
Signalling Purposes.
I, GEORGE ROSE of 70 Wellington Street, Glasgow, Lanarkshire, 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:
This invention relates to that class of spray lamps for heating, lighting and signalling
purposes, wherein compressed air or sleam is used to spray the oil; and it has for its
object to simplify and improve the construction and arrangement of the parts of lamps
of this class

page_text: And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon-
Fig. 1 is a sile elevation and fig. 2 a section of a burner for use with the lamp.
Fig. 3 is a vertical section of a slightly different arrangement of the burner. Fig. 4
is a side view partly in section of the head of the lamp with a signalling arrangement
attached. Figs. 5 and 6 are sectional views of lamp burners and combustion boxes.
Figs. 7, 8 and 9 represent in side elevation, plan, and tranverse section, respectively,
a four way cock. Fig. 10 shows a signalling arrangement whilst fig. 11 shows a wind
guard arrangement. Figs. 12 and 13 are detail views.
On the drawings wherever the letters of reference are repeated, similar or like parts
are indicated.
Figures 1 and 2 show a spray burner of novel construction and which consists of a
bollow body or chamber A, having the top part hollowed out by preference to a cup
shape as shown at figs. 2 and 3 or inverted conic shape as shown at fig. 12 for the
purpose of preventing any carbon or other matter which may be sucked into the
vacuum at the spray orifice from accumulating and choking said orifice. The cup
shaped top part may be a separate piece and be screwed into the top of the hollow
chamber A if desired. Through the top or cover of the hollow chamber a hole or
channel B is bored for the passage of the compressed air or steam which enters the
hollow chamber A through a lateral branch C. To filter the air or steam from sealo
or grit, before passing to sail outlet hole B, I may affix thereto or therein a small
cylinder or piece of perforated metal D (or wire gauze or equivalent may be used)
through which the air or steam passes and is filtered in its passage. The oil to be sprayed
and burned is also led through a lateral passage E, preferably, bored through the top
or cover of the hollow chamber A, as shown, although the burner may be made thicker
on one side and the oil passage be bored vertically up through that side if so desired.
The floor of the hollow chamber may either be cast in one piece with the chamber or
may be constituted by a screw plug F or its equivalent. When a screw plug is
used it enables the channel B and chamber A to be easily cleaned out.
it
Under a modified construction instead of the burner A being made as hereinbofore
described, it may consist of a solid cylindrical piece of metal, as shown at fig. 3, in
which is bored or formed in the direction of its length the air or steam channel or
way B; meeting this channel, preferably at a point near to the outer and of the
burner, as shown, is the oil channel or way E bored through the solid metal, and
preferably made, at its upper end, at right-angles to the air or stream channel. The
longitudinal air or steam channel B is, by preference, made or bored, from the point
of junction between it and the oil channel, E, to the outer end of the burner, of a
slightly larger diameter, and is, preferably, slightly tapered as shown. The outer end
of this burner is also, preferably, hollowed out into a cup or inverted conic shape.
As will be seen in this arrangement the burner, is screwed on to the top of the stand
pipe G of the lamp. The oil from the oil tank passes up the pipe G whilst the air or
steam passes up the small pipe H from the source of supply in the same or similar
manner to that described in my prior patent No. 1649788.
Either the burner A, or the burner W figs. 5 and 6, is or may be surmounted by
a combustion box I which is somewhat of the same construction as that describer
under my prior patent No. 359 of 1888, and consists of an outer casing or cylinder J
in which is supported concentrically by hangers J¹ or equivalent, another preferably
shorter cylinder J². In the annular space formed between these two cylinders, I
insert a superheating coil pipe K, one end of which communicates by the passage K
(in the solid pieco a) and pipe H in the stand tube G with the air or steam supply
In some
whilst the other end communicates with the chamber W2 of the burner.
cases and especially when the lower end of the outer cylinder of the combustion box
is made tapered as shown at fig. 5 so as to be easily fitted on the burner, instead o
fitting the superheating coil pipe K in the annular space between the concentri
cylinders J, J it may occupy the space between the lower end of the inner cylinder J
and the top of the burner W. At the point where the superheating coil pipe K join

page_text: the burner, a small drip tube or chamber L (fig. 5) may be fitted, for collecting any
condensed water or dirt, this drip chamber would by preference be provided with a
small draw off cock or tap M at its lower end.
The oil to support combustion, and the air or steam, as the case may be, to spray
the oil, are each conducted from their respective sources of supply to a regulating
valve or cock N of novel construction, see figs. 7, 8 & 9. This valve or cock N which
may be fitted on top of the stand tube of the lamp or on top of the basement tank
or reservoir or in other convenient situation consists, preferably, of a hollow
barrel of cylindrical or other shape having four openings or ways formed in it, two on
each side; the two (N1 N2) on one side constituting, respectively, the steam or air inlet
and outlet and the two (NN) on the other side constituting respectively the oil inlet or
outlet. In the barrel of the cock is fitted a plug or key P, capable of being easily turned
by a handle or wheel as usual and which has bored in it two elbow shaped channels
or ways as shown, which, when the cock or valve is turned slightly round, opens
communication between the oil inlet N and outlet N and the air or steam inlet N'
and outlet N simultaneously; likewise, when the plug is turned back or reversed, the
air or steam and the oil are both shut off synchronously. For the nice adjustment of
the oil and air or steam supply. I, by preference, fit on the valve or cock a dial
plate O; a finger or pointer P fitted to the key or ping P of the valve or cock
indicating thereon the degree to which the valve has been opened or closed. The
ways or channels in the key or plug instead of being elbow shaped, as herein before
described, may be straight and the valve or cock may be otherwise slightly altered to
meet varying circumstances.
The oil and the air or steam from the four way valve or cock may be led by two
separate tubes G, H to the burner, these tubes may be for the sake of compactness,
either both enclosed in a third tube which may constitute the stand pipe supporting
the burner and combustion box in the same manner as described under my prior patent
No. 164978 or they may be enclosed the one within the other as shown at figs. 3, 4,
5 and 6, the tube G being for oil and the tube H for air or steam.
The oil before passing to the burner to be sprayed would, preferably, have its supply
regulated and controlled by a regulating apparatus, as shown at fig. 4, consisting of a
hollow box or casing Q surmounted by a suitable lid or cover Q which may, if
desired, be provided with an air valve at top. A draw off cock may be fitted at the
bottom of the casing if required. Into the box or casing Q is led the oil supply
pipe R which has, at its end, an outlet valve S which is preferably constructed of a
solid piece S forming the valve seat and having a plug S screwed into it; through
the plug works the valve spindle which is surmounted by the valve S³. A small
spring S is also provided for counter balancing the woight of the float T. Any other
suitable arrangement of valve may however be used. The outflow of the oil through
the valve S, is regulated and controlled by the cylindrical float T. A ball or
equivalent float may, however, be used instead of a cylindrical one. The spindle of
the valve S is connected to the float so that when the oil in the casing rises above a
certain level the float rises and in so rising shuts the valve S3 and cuts off the supply,
when the oil level falls, the float also sinks and so opens the valve S. The oil issuing
from the regulating box or casing Q is made to pass, for the purpose of preventing,
as far as possible, any grit or dirt passing along with the oil to the burner, by
preference, through a small cone U having a hole at its apex, situated in the pipe U
leading to the burner. In the view fig. 4 the valve or cock N is shown as fitted in
the oil supply pipe U. In the arrangement shown in this fig. the oil from the source
of supply passes from the pipe G through a tee-piece c. pipe R and syphon R to the
oil regulator Q from whence it passes through the cono U into the valve N and thence
to the burner by the pipe b. The air or steam likewise passes from the supply up the
pipe H shown partly in dotted lines through the channel H' (shown dotted) in tho
solid piece d and pipe connection e to the valve N from whence it passes by the pipe f
to the burner. When, however, the four way valve is not used, the pipe U com-
municates direct with the burner and a tap or valve is provided on it for opening and
cutting off the oil supply.

page_text: When the lamp is used for heating purposes and the burner is placed on its side;
the oil supply pipe may be connected direct to the burner by a tee or cross piece V
as shown at fig. 12; the head of the tee or one of the branches of the cross piece
being in line with the oil passage in the burner. When a burner such as shown
at figs. 1 and 2 is used, the outer branch of the tee or cross piece is oither left open
or it may be closed by an easily removable screw plug. With this arrangement the
oil passage in the burner, as will be seen, can be easily cleaned by passing a wire
or rod down the head of the
or the branch of the cross piece and into the
88
tev
23
oil passage.
When my improved lamp is to be used for signalling purposes, I, by préference,
use a hollow cup shaped burner W as shown at figs. 5 and 6, in which the air or
steam nipple is centrally secured and communicates with a hollow air or steam
chamber forming the base of the burner, into which the steam or air supply is led
by the pipe K. In this form of burner the oil is forced under pressure from the
oil tank of the lamp up the stand tube G through the channel a in the solid
piece a' and so by the pipe Y to the annular space a³ formed between the wall of
the burner cup and the inner rim a. From the annular space as the oil trickles
through holes formed in the rim or wall a or otherwise, into the cup and so to
the point of the burner nipple W. For the purpose of keeping a light continually
burning in the combustion box, during the periods when the oil and air or stenin
supply to the burner is cut off I, by preference, insert in the annular space ³ an
asbestos or other wick a similar to that described in my prior patent, No. 1649788
which will keep alight during the periods, hetween the flashes, and will, on the oil
spray being again turned on, instantly relight it. Instead of the burner hereinbefore
described, I may use a burner similar in construction to that described under my
prior patent No. 11517 of 1888 which consists of a chamber such as W, fig. 6, in the
centre of which the steam or air nipple is secured, the chamber has a small hole at
top through which the steam or air nipple projects. Under this invention I cast on
or screw into the top of the chamber W a cylindrical piece X which is raised up
conewise in the centro at X¹ so as to form an annular space into which an asbestos
or other wick as may be placed for relighting the spray jet when desired. The
coned part is so formed as to leave between it and the nipple W an annular
orifice for the oil. In fig. 5, the oil pipo Y is bent over as shown, and the oil trickles
on to the wick a. In fig. 6 the pipe Y communicates directly with the oil chamber
of the burner. A grit or dirt filter D is preferably provided as shown at fig. 6.
When it is desired to turn off the oil and air or steam, or the oil only, so as to put
out or lower the flame when signalling, I prefer, in all cases where the controlling
valve or cock is situated some distance above the ground, or in the case of a vessel,
above the deck to affix a quadrant Z (as shown attached to the cock N at fig. 4) or a
bell-crank lever as shown at fig. 18 or an equivalent device to the handle, key or
spindle of the valve or cock, which can be actuated by cords Z or wires or chains so
as to turn the key of the cock round and so turn the oil or air or steam, as the case
may be, on or off at will. In some cases, where a bell-crank lever or a quadrant is
used, a spring Z³ (fig. 4) may be so fitted to one arm or end, as to keep the valve
opened or closed whilst a cord Z wire, rod or equivalent is attached to the other end
and on being pulled from below closes or opens the valve.
When it
In some cases for signalling or other purposes a cylindrical casing g, see fig. 10,
may be fitted on the lamp so as to enclose the combustion box I this casing
on being raised, by means of a cord or a wire, rod chain or equivalent acting
on the lever j, or its equivalent fulcrumed at j and catching on the underside of
the casing so as to lift it up, encloses the light and hides it from view.
is desired to show the light, the pressure is taken off the cord, rod, chain or
equivalent and the casing then falls by its own weight. The casing, when the
light is not far above the ground, may, if desired, be lifted up to obscure the
light, by means of handles secured to it or to rods or their equivalent attached to
its underside.
A wind guard (fig. 11) may be fitted to the lamp being secured in position by a

page_text: ring in passing round the stand pipe G or round the lower end of the burner or the
combustion box I and being free to move thereon. The guard I may also be secured
by another ring or equivalent fitted round the upper end of the combustion box and
moving freely thereon if so desired. From these rings, rods or stays or equivalent
may be fitted so as to hold the guard in position or the guard may be secured directly
to the ring m as shown. A vane o may, if desired, he secured to the guard or to the
rods attached to it, to keep the guard always with its back to the wind and so shield
the flame.
In many instances, the arrangements which have been described for the steam or
air supply may be used for the oil supply, and, vice versa, the oil supply arrangements
be used for the steam or air. My improved lamp may be used for heating as well as
illuminating and signalling purposes and when so used in connection with any furnace
or arrangement for heating boilers, smelting, and for other purposes, the flame would
by preference be directed horizontally into the furnace or chamber to be heated. The
form of burner shown at figs. 1, 2 & 3 would he preferably used for heating
purposes.
