I, HENRY DARBY, of 123, Caledonian Road, London, in the County of Middlesex,
Stove Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in apparatus or machines for generating
and burning gases or vapours from hydrocarbon oil (.e. liquid hydrocarbon) and
water fed to the apparatus as required and is designed to produce a more perfect
ajparatus than hitherto and also otherwise improve the construction thereof.
My present improvements relate to apparatus of the character described in the
specifications of an application for Patent by Samuel M. Biddison dated. the
80th August 1888 No. 12.467 and consists firstly in replacing the cast iron steam's
generator described and shown by the said Biddison with a wrought iron or other
suitable metal (such as copper) pipe or chamber into which the water (controlled by
a suitable valve-or cock which is advantageously situated both as to the oil and water
supply between the regulator and the apparatus) is fed direct from a regulator such
as hereinafter described which allows the required amount of water to flow into the
aforesaid pipe or steam generator. In Biddison's and other like machines when very
great heal is obtained such boilers have been liable to crack thus injuring such
apparatus: whereas by my modifications such injury is noi so likely to take place
whatever the heat.
In apparatus of a large size or to keep up continuously very great heat it has been
found very difficult to keep an even flow of water into the steam generator chamber
and for the purpose of regulating both the water and the oil feed supply I have.
found that a very efficient regulator may be made by forming a cistern or reservoir
to hold the water (or oil) from which it is fed to the apparatus by means of syphon
action, if desired a well being formed in the bottom of the reservoir into which the.
lower end of the syphon inlet pipe enters and having a grating or strainer over this.
well to prevent dirt or other solid matter entering the pipe.
A further addition and improvement consists in arranging an extra series of pipes
(for drying and superheating the steam before it is mingled with the oil) above the.
chamber or pipes for superheating the combined oil and water vapours and this.
addition is of the utmost importance when an intense heat is required as it not
only assists to keep the steam pressure more even but greatly increases the heat,
producing power of the apparatus.
I wish it to be clearly understood that my said improvements may be applied to,
the said Biddison apparatus (or to other similar apparatus to which such improve-
ments are or may be found applicable) either collectively or separately as desired
thus in some cases where very great heat is not required the improved steam
generator and syphon regulator may be used alone without the addition of the
extra series of steam superheating pipes or passages.

Improvements in Apparatus for Generating and Burning Gases
from Hydrocarbon Oil and Water.
T, HENRY DARBY, of 123, Caledonian Road, London, in the County of Middlesex,
Stove Maker, 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 improvements in and in connection with apparatus or
machines for generating and burning gases or vapours from hydrocarbon oil (i.c.
liquid hydrocarbons) and water fed to the apparatus as required and is designed to
produce a more perfeci acting apparatus than hitherto and also otherwise improve
same.
My present improvements relate to apparatus of the character described in the
Specification of an invention for which Samuel M. Biddison has received Letters
Patent dated the 30th August 1888 No. 12.467 and cousists firstly in replacing the
cast iron steam generator described and shown by the said Biddison with a wrought
iron or other suitable metal (such as malleable iron or copper) pipe or chamber
into which the water (controlled by a suitable valve or cock which is advantageously
situated both as to the oil and water supply between the regulator and the apparatus)
is fed direct from a regulator such as hereinafter described, which regulator allows
the required amount of water to flow into the aforesaid pipe or steam generator
chamber. In Biddison's and other like machines when very great heat is obtained
such boilers have been liable to crack thus injuring such apparatus: whereas by
my modifications such injury is not so likely to take place whatever the heat.
In apparatus of a large size or to keep up continuously very great heat it has been
found very difficult to keep an even flow of water into the steam generator chamber and
for the purpose of regulating both the water and oil feed supply I have found that a
very efficient regulator may be made by forming a cistern or reservoir to hold the
water (or oil) from which it is fed in the apparatus by means of siphon action-if
desired a well being formed in the bottom of the reservoir into which the lower end
of the siphon inlet pipe enters and having a grating or strainer over this well to
prevent dirt or other solid matter entering the pipe and this siphon feed regulator
(adjusted as to its position with regard to the burner as hereinafter explained) forms
a very important part of my present invention.
A further addition and improvement consists in arranging an extra series of pipes
(for drying and superheating the steam before it is mingled with the oil) and this
addition is of great importance when an intense heat is required as it not only assists
to keep the steam pressure more even but greatly increases the heat producing power
of the apparatus.
I wish it to be clearly understood that my said improvements may be applied to the
said Biddison apparatus (or in other similar apparatus to which such improvements
are or may be found applicable) either collectively or separately as desired-thus in
some cases where very great heat is not required the addition of the extra series of
steam superheating pipes or passages may be dispensed with.
And in order that my present invention may be easily understood and readily
carried into practice I will proceed to further describe same with reference to the
accompanying drawings.
DESCRIPTION OF THE DRAWINGS,
Fig. is a perspective view part being broken away to shew the interior of a
regulator in accordance with my invention for the oil and water feed of liquid hydro-
carbon and water burners generally to which it is or may be applicable.
Fig. 2 is a perspective view of the apparatus (for generating and burning liquid
hydrocarbon and water gases or vapours) having the extra series of steam superheating
pipes arranged thereon."

page_text: Fig. 3 is a cross section on the line e, fig. 2 looking in the direction of the
arrow .
Fig. 4 is a cross section of such apparatus with these extra steam superheating
pipes or chambers arranged in a somewhat different manner.
Similar letters of reference indicate corresponding parts throughout.
u is the steam generator or boiler from which the steam passes to the first of the
extra series of superheating pipes or chambers 6 and thence by the bend b' to c.
thence round the bend to and through the bend into e where it meets and
mingles with the oil or oil vapours and the two vapours or gases (as it may be) then
pass round the rest of the pipes in the manner and for the purposes fully set forth
in Biddison's said specification-is: from they pass round bend e f f g gh and
bend to the outlet holes in i.
The steam passing around through the pipes or superheating chambers b, c, d,
which are intensely hot is thereby dried and superheated before reaching the pipe e
where it is mixed with the oil the result being a greatly increased heating power of
the burner or apparatus.
The series of pipes or superheating chambers b, c, d, may for compactness be
arranged over the pipes, as shewn in Figs. 2 and 3 or if desired may be arranged
and mounted about on a level with same as shewn in Fig. 4, this latter arrangement
thus making a wider apparatus and consequently spreading the heat produced by
the apparatus over a wider area.
Fig. shews a convenient form of double reservoir one compartment being for oil
(liquid hydrocarbons) and the other for water.
The syphon action is advantageously obtained by arranging the feed pipes m
(say for the water) and (say for the oil) as shewn so that the inner ends
thereof and respectively are at or near the bottom of the reservoir or in a
well formed in the bottom of the reservoir and having a grating or strainer p
arranged thereover to prevent as far as possible any solid matter entering the
pipes. 7
is lid or covering to opening for filling the vessel.
The syphon action is started by simply filling the reservoir above the level of
bend mor n of the pipes m or n-draw off cocks or laps being provided at about
the point
s or at any other convenient point to let out any air which may have got
into either pipe as otherwise such air would interfere with the syphon action
commencing.
The adjustment of the height of this reservoir at the proper level above the oil
inlet pipe
e of the apparatus is of the utmost importance to the proper working
of the burner and can be easily ascertained in each case according to the size of
the burner apparatus in the following manner which I give as an instance but it can
be determined in any other suitable and convenient manner.
With an apparatus 36 inches in length and superheating pipes of one inch internal
diameter or thereabouts I should first fix the reservoirs (which may be made separate
or may be combined in one case as shewn in Fig. 1) at a height of about 18 inches
above the level of the pipe of the burner apparatus.
At the same time I introduce a small temporary cistern with a piece of india
rubber or other flexible tubing on either side thereof between the water reservoir
and the steam generator of the burner and start the burner in action.
As soon as
it is fully in action I then find the exact adjustment required by raising or lowering
the above temporary cistern (the flexible tubing permits this to be done) until the
appearance of the burning gases or vapours shows the best position for the level of
the water that is I thus give greater or less pressure of water according to the height
from which same descends.
Having thus found the exact position required so as to give the best possible
result I then affix or mount the reservoir itself, in its permanent position at the
height determined the flexible tubing and the temporary cistern being entirely
removed and the proper feed pipes are then duly connected up-The apparatus is
then all ready for practical operation.

page_text: The correct adjustment as to the height (ie, the pressure) of the water is an
important factor to the successful working of apparatus for burning liquid hydro-
carbons and water of the character-or analogous to that—hereinbefore described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
elain is:-
1. A feed water regulator supplying water by syphon action from a reservoir to
the steam generator of an apparatus for generating and burning gases or vapours
from hydrocarbon oil and water.
2. A feed water regulator for supplying water to the steam generator of an
apparatus for generating and burning gases or vapours from hydrocarbon oil and
water arranged and acting substantially in the manner and for the purposes herein-
before set forth.
3. The improved feed water regulator supplying water by syphon action through
a pipe such as having a bend m and leading from the reservoir to the steam
generator of an apparatus for generating and burning gases or vapours from hydro-
carbon oil and water arranged and acting substantially in the manner and for the
purposes hereinhefore described and represented in Fig. 1 of the drawings hereunto
annexed.
4. In apparatus of the character hereinbefore set forth for generating and burning
gases or vapours from hydrocarbon oil and water I claim the series of steam super-
heating pipes b, c, d, arranged and acting substantially in the manner herein before
described and illustrated in the drawings hereunto annexed.
5. In apparatus of the character herein before set forth for generating and burning
gases or vapours from hydrocarbon oil and water I claim iwo or more superheating
pipes introduced between the steam generator and the point where the steam meets
the oil such pipes being arranged so that they will be intensely heated by the
burning gases or vapours substantially in the manner and for the purposes herein-
before set forth.
