Improvements in and relating to Oil Spray Lamps.
We, WILLIAM HENRI LUTHER, and EDGAR MANSFIELD BAYLEY, both of
the firm of Frederick Braby and Company, Manufacturers, of Petershill Road,
Glasgow, Lanarkshire, and JAMES COCKBURN, Engineer to said firm, do hereby
declare the nature of our invention to be as follows:-
This invention has reference to and comprises improvements in and relating
to portable oil spray steam lamps in which water and oil are forced or taken
from separate vessels or separate compartments of vessels to a steam generating
and flame combustion chamber and sprayed there through burners or nozzles.
In carrying the improvements into practice one vessel or close chamber of a
vessel is used for the oil, which does not require much pressure, and another
strong vessel or chamber for containing the water to sustain very considerable
pressure as from 40 to 100 pounds for producing the steam to spray the oil all
as hereinafter described. Oue improvement consists in using two, three or more
separate lights or lamps with their combustion chambers and fittings and separate
oil and water pipes and steam spray pipes and nozzles, cach controlled by
separate cocks or valves from one oil and water tank. One arrangement of
these multiple spray lights consists in fitting two lights on opposite sides of the
portable water and oil vessels, either carried on brackets or on the pipes con-
necting them with the vessels. Each light would be formed or fitted with an
oil supply and steam nozzle burner for spraying the oil. The oil nozzle may
be of the inverted hollow conoidal shape for the oil to pass into it, towards the
centre steam jet nozzle, which would spray the oil up into a combustion chamber
with annular steam generating and superheating chamber to the lower part of
which the water would be led from the water chamber where it would be con-
verted into steam and led from the upper part down to the steam spraying
nozzle. While another branch of this pipe would lead into the upper part of
the water vessel and produce pressure with the steam on the surface of the
water, and force it up into the steam generating chamber so as to produce an
automatic working light when once started. A jet of the said steam would be
taken from the upper part of the water vessel by a tube conducted through the
other light or lights to the spray nozzle and so be superheated on its way to
this second or other lamp, which would thus not require a steam generating
chamber for spraying the oil up into its combustion chamber, but when three
or four lights were wanted, two of them would preferably have steam generating
and superheating vessels, and these lights might all take their spraying steam
from the water vessel led by separate pipes through the flames to the spraying
nozzles of the burners the steam being supplied to the water vessel by the lights
which have steam generating chambers. The oil might be supplied to the oil
burner of each light cither by gravitation from the oil vessel, or be raised up
to the burner by a steam injector nozzle when the light is placed above the oil
vessel. The spray burner nozzle itself might be made such an oil injecting
nozzle, or a special nozzle might be fitted to each tube to raise the oil from
the oil supply chamber to the inverted conoidal spraying nozzle before mentioned;
or otherwise the pressure of the steam in the water vessel may be made to act
on the top of the oil by a separate pipe and cock to raise the oil to the steam
spraying burner, and a tray or other floating cover may be placed above the
oil to prevent condensed steam acting on and mixing with the oil in the vessel.
This light is or may be started by the insertion of a small tray of naptha
kerosene or other inflammable oil or spirits or cotton waste saturated with saine

COMPLETE SPECIFICATION.
Improvements in and relating to Oil Spray Lamps.
We, WILLIAM HENRI LUTHER, and EDGAR MANSFIELD BAYLEY, both of the
firm of Frederick Braby and Company, Manufacturers, of Petershill Road,
Glasgow, Lanarkshire, and JAMES COCKBURN, Engineer, to said firm, do hereby
declare the nature of our said invention, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement in writing, that is to say :-
This invention has reference to and comprises improvements in and relating
to portable oil spray steam lamps in which water and oil are forced or taken
from separate vessels or separate compartiments of vessels to a steam generating
and flame combustion chamber and sprayed there through burners or nozzles.
And in order that our said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, we have hereunto
appended an explanatory sheet of drawings, in which
Figure 1 is an elevation mostly in section, and Figure 2 a plan view of one
arrangement of our new or improved oil spray lamps complete.
Referring to these drawings. In carrying the improvements into practice one
vessel or close chamber of a vessel A is used for the oil, which does not require
much pressure, and another strong vessel or chamber B for containing the water
to sustain very considerable pressure as from 40 to 100 pounds for producing
the steam to spray the oil as hereinafter described. The improvements
essentially consist in using two, three, or more separate lights or lamps with
their combustion chambers and fittings and separate oil and water pipes and
steam spray pipes and nozzles, each controlled by separate cocks or valves from
one oil and water tank. One arrangement of these multiple spray lights as
shown in these drawings, consists in fitting two lights C, C, D, on opposite
sides of the portable water and oil vessels B, A, either carried on the pipes
connecting them with the vessels B, A, or on brackets. Each light would be
formed or fitted with an oil supply and steam supply nozzle burner C C¹ for
spraying the oil, preferably fitted with a cleaning cock C". The oil nozzle may
be of the inverted hollow conoidal annular shape with a series of holes for the
oil to pass into it, towards the centre steam jet nozzle as described in the
Specification of former Patent No. 1172 22 Jany. 1890 which would spray
the oil up into a combustion chamber D with annular steam generating and
superheating chamber D' fitted with drain cock D" shown on the left hand side
of these drawings, to the lower part of which the water would be led from the
water chamber B by a pipe B3' fitted with a cock or valve B", where it would
be converted into steam and led from the upper part of this chamber D' by a
pipe b and branch coupled to it at 6 down to the steam spraying nozzle
at C and would get superheated in passing through the combustion D.
While
another branch also coupled at 61 to this pipe would lead into the upper
part of the water vessel B and produce pressure with the steam on the surface
of the water, and force it through the pipe B up into the steam generating
chamber D' so as to produce an automatic working light when once started. A
pressure gauge and safety valve would be fitted at B on the top of the vessel B
to indicate the steam pressure within and relieve it should it get too high. A
jet of the said steam would be taken from the upper part of the water vessel B
by a tube c, controlled by a cock or valve c' conducted through the combustion

page_text: chamber D and so be superheated on its way to the burner C' of this second
or other lamp, which would thus not require a steam generating chamber D¹ for
spraying the oil up into its combustion chamber; but when three or four lights
were wanted, two of them would preferably have steam generating vessels D',
and these lights might all take their spraying steam from the upper part of the
water vessel B, led by separate pipes through the flames to the spraying nozzles
of the burners the steam being supplied to the water vessel by the lights which
have steam generating chambers D. The oil would or may be supplied to the
oil burners or C₁ of each light either by gravitation from the oil vessel A
led by pipes a controlled by cocks or valves a' as shown in these drawings; or
be raised up to the burner by a steam injector nozzle when the light is placed
above the oil vessel. The spray burner nozzle itself might be made such an
oil injecting nozzle, or a special nozzle might be fitted to each tube to raise
the oil from the oil supply chamber to the inverted conoidal spraying nozzle
before mentioned; or otherwise the pressure of the steam in the water vessel B
may be made to act on the top of the oil in the vessel A by a separate pipe
and cock to raise the oil to the steam spraying burner, and a tray or other
floating cover may be placed above the oil to prevent condensed steam acting
on and mixing with the oil in the vessel. This light is or may be started by
the insertion of a small tray of naphtha, kerosene, or other inflammable oil or
spirits, or cotton waste saturated with same above the burner C or C¹ and below
or within the combustion chamber D until the steam is generated.
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 :-
First. The construction, or arrangement and combination of the parts of an
oil spray lamp, with oil and water chambers, and steam water and oil pipes and
valves and connecting fittings, substantially as herein described in reference to
and by way of application shown in the accompanying drawings.
Second. In oil spray lamps, the fitting and use of two or more lights or lamps
round the liquid supply tanks, substantially as herein described, in reference to
and by way of application shown in the accompanying drawings.
Third. In oil spray lamps the combination comprising two or more lights or
lamps with combustion chambers and burners, oil and water chambers or tanks,
and connecting pipes and valves, steam generating chamber or chambers and
pressure distributing pipes, substantially as herein described, in reference to and
shown in the accompanying drawings.
Fourth. In oil spray lamps, the combination comprising two or more burners
and combustion chambers to which the steam is supplied from one steam
generating chamber, substantially as herein described, in reference to and by
way of application shown in the accompanying drawings.
