page_text: We, THOMAS CLARKSON of Grove Villa, Carshalton Grove, Sutton, in the County
of Surrey, Engineer and HERBERT CHURCHILI. CAPEL of 168 Dalston Lane, in the
County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to burners for oil to be vapourized and burnt as a vapour;
it is particularly adapted for heating purposes, but may be used for lighting
purposes also.
In carrying out the invention we provide the necessary number of nozzles which
may be made of any suitable material-steel for example and each is by preference
carried upon a tubular or other support, upon which it is clipped, so that it
may be adjusted. Each nozzle is connected with a vapourizer consisting pre-
ferably of a flattened tube, upon which the jet of vapour from the nozzle impinges.
Each vapourizer is carried substantially in the manner described with reference
to the nozzles, so that the plane in which it lies may be varied; each vapourizer
is connected with the supply of oil which reaches it by gravity. In the tube
supplying the oil to the vapourizer, we employ an anti-fluctuator consisting of a
bunch of wires in the tube or an enlargement thereof, so as to regulate the supply.
of oil. To accommodate the variation due to expansion and contraction or to
other circumstances, we prefer to zig-zag the pipe or a portion of it.
To prevent accumulation of air in the supply pipe, which would have the effect
of stopping the supply of oil we provide a tap or equivalent, by which a rush
of oil through the pipe may be obtained when necessary; the oil from the tap may
be returned to the reservoir in any convenient manner. We also prefer to connect
the lowest level of the supply pipe with the upper portion of the oil reservoir by
an intermediate pipe.
In order to regulate the escape of vapour each nozzle is provided with a plug,
needle or equivalent, which serves two purposes: first, to regulate the size of
the orifice through which the vapour escapes, and second, to scrape or clean out
the orifice in the nozzle, so as to remove deposits. The shape of these plugs,
which for convenience we will term needles, may be varied, but we find they
work well when they are circular in cross section, the extreme end being parallel,
the next portion tapered and beyond that parallel again, but of a larger diameter,
approximately equal to the orifice of the nozzle, so that when forced in, it will
remove any deposit, but without jamming in the nozzle.
Each needle is carried upon an arm clipped upon a tubular or other rocking
shaft, so that a reciprocating motion can be imparted to all the needles simul
taneously or separately if preferred. Each needle is quite loosely attached to its
arm, so that it may easily accommodate itself to any variations in the positions or

page_text: angles of the nozzles etc.; for this purpose any suitable joint-ball and socket
or other may be employed, but we have obtained satisfactory results by merely
bending the end of the needle into a hook or loop, which would pass through a
hole on the end of the arm.
The vapourizers are arranged with sufficient space between them, through which
the flame after impinging upon the vapourizer passes to heat the boiler or furnace.
The adjustment of the part of the vapourizer is useful in conjunction with the
angle at which the vapour impinges upon it to regulate the flame produced, so
that it shall rise up between the vapourizers in the required position, and not,
as might otherwise happen, be driven chiefly to one part.
Special deflectors or equivalent may, however, be employed to regulate the flame
if required.
The application of the needles for the purpose of regulating the amount of
vapour escaping from the nozzles, and consequently the heat of the furnace, may
be effected by hand or automatically; for the purposes of hand regulation, any
convenient mechanism for example wedge screw or the like-may be employed.
Where the application of the burner is such that steam or other pressure is
available, the automatic regulation is effected by that pressure operating upon
the following mechanism: A tube is blocked at one end by a diaphragm, outside
which is a cap forming a chamber open to the pressure, say that of the steam
boiler; inside the tube is a spring bar preferably of metal, and of suitable shape,
conveniently flat, supported inside the tube at the end remote from the diaphragm,
by an adjustable stop, preferably screw-controlled; the other end of the bar is
supported either directly or indirectly by the diaphragm, preferably in order to
obtain the movement of the whole surface of the diaphragm by a block, which is,
in effect, a piston, loosely-fitting-in-the-tube.-The-ends_of_the_rod are preferably
flattened to approximately knife edges, which are placed out of the centre in
order to make the rod always bend to the same side. The knife edges; engage
with V-grooves or equivalent in the piston, and the end of the screw or piston
or plate appertaining thereto. The movement of the rod is taken off from the
centre or thereabouts by a rod or equivalent passing through the wall of the
tube, which is connected by any suitable mechanism with the rocking shaft before
mentioned. For cleaning purposes, a greater amount of movement may be
temporarily imparted to the rocking shaft by hand apparatus.
To prevent back-lash and generally to return the spring rod to its normal
position, we may employ a weighted arm or lever, preferably provided with a
stop so as to regulate the amount of possible movement, while another stop may
be placed inside the tubular casing, upon which the spring rod will rest when not
subjected to the pressure. This second stop may be used instead of or in addition
to the placing of the knife edge bearings out of the centre, in order to make
the rod bowed to the proper side.
We find that when the flame is turned down low it is difficult to obtain the
necessary regularity, and for this purpose we prefer to form a notch or channel
either in the needle, or in the nozzle, or in both.
If desired the vapourizer instead of being a single flat tube, as previously
mentioned, may be divided into two limbs, between which the flame when reduced
would. pass, so as not to impart so great a heat to the vapourizer when a low
flame only was required. When the flame is turned up it would cover both limbs
of the vapourizer.
To prevent the oil being turned on from the reservoir until the vapourizers
were properly heated, the following device may if desired be employed: The tap
or equivalent by which the oil is supplied to the vapourizers may be connected
with a vessel containing metal fusible at a low temperature; until this metal
is fused the tap could not be turned, but as soon as sufficient heat was obtained
in the vapourizers the metal would melt and the tap be operated.
Instead of separate vapourizers a single vapourizer may be employed supplied
with oil as before, and operating one, or if. preferred more than one jet nozzle,

conveyed by a tube, and burnt in jets in any desired form.

Improvements in or relating to Oil and similar Burners.
We, THOMAS CLARKSON of Grove Villa Carshalton Grove, Sutton in the County
of Surrey, Engineer and HERBERT CHURCHILL CAPEL of 168 Dalston Lane, in the
County of Middlesex, 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:-

vapourizers the metal would melt and the tap be operated.
Instead of separate vapourizers a single vapourizer may be employed supplied
with oil as before, and operating one, or if preferred more than one jet nozzle, the
vapour from which mixed with air somewhat like a Bunsen burner, may be
conveyed by a tube, and burnt in jets in any desired form.

Like letters indicate like parts throughout the drawings.
From the fuel supply tank A leads a pipe B provided with a cock B¹ and
zigzagged as shown to allow of expansion and contraction and elastic connection
between the burner and supply tank. On the lowest point of this pipe is situated
a second cock B2, by opening which any air which may have accumulated in
the pipe B can be got rid of in order to enable the oil to flow freely to the
vapourizer. Between the tube B and the vapourizer is introduced an anti-fluctua-
tor in the form of a tubular casing C which is packed with fiue wires C. The
oil in passing through this casing is broken up into a series of very fine streams
which control its movement and cause it to pass into the vapourizer D) in a steady
stream. The vapourizer may consist of a Hattened tube as shown in Fig. 4 in
which D¹ is the end of the tube through which the oil issues on its way from
the anti-fluctuator C³.
The vapourizer is preferably set in an inclined position, as clearly shown in
Figs. 1 and 2 and in a tube which passes to a nozzle F which is so arranged
that the flame from the vapour issuing from it impinges upon the vapourizer D.
The nozzle comprises a cylindrical casing with a conical end F, which has a
parallel hole F2. Into the opposite end of the nozzle is screwed a plug G which
carries an extension G¹ by means of which the whole nozzle and the end of the
vapourizer are supported.
A tubular rod H suitably supported carries a clip J which may be clamped by
the bolt J at any point and angle that may be desired. The clip J carries a
projection J2 which is formed conical, externally screw-threaded, bored to receive
the extension G¹ of the plug G, slit longitudinally and provided with a nut J³.
This arrangement enables the extension G to be firmly held in the socket Ja
while being capable of adjustment. The position and angle of the nozzle and
vapourizer is also adjustable by moving the clip J upon the supporting shaft H,
such adjustment causing the flame to impinge upon any desired part of the
vapourizer. The flow of vapour from the nozzle is regulated by the suitable
movement of a needle K whose tapered end projects into the opening F of the
nozzle. The needle is tapered as at K¹ the extra point K2 being formed parallel
in order to prevent the end of the needle from falling out of the opening 12 when
the tapered portion is withdrawn to its fullest extent.
The main part or shank of the needle is formed of such a diameter that when
desired it can be passed right through the opening F in order to clear the latter
of any deposit, the needle thus fulfilling the double purpose of regulator and
cleaner. A channel, flat, or groove K³ is cut on one side of the tapered portion
of the needle in order to obtain regularity of flame when the vapour is turned
low. If preferred the channel may be cut in the nozzle in place of in the needle.
In order to adjust the needle K it is loosely carried on the end of a rod L.
The connection being preferably in the form of a hook upon the end of the
needle engaging with an eye upon the flattened end of the rod, this connection
being arranged to be a loose fit in order to allow of the free movement of the parts
.after expansion.

page_text: The end of the rod L is clamped to a pivotted shaft or tubular rod M by a
device which allows of both radial and angular adjustment, of the rod L upon
the shaft M. This clamp which is shown in Fig. 2 and also clearly in Fig. 6,
comprises a clip N which encircles the shaft M and is provided with a straight
portion N upon one side having a V-shaped groove cut in it in which lies the
end of the rod L. A strap N2 which embraces the two arms of the clip and also
the rod L is provided with a set screw N³ by means of which the rod is firmly
held and the clip caused to grip the shaft M. A single fastening thus serves
for the two adjustments.
If desired a clip such as J J J J may be employed to attach the end of the
rod L to the shaft M or this form of clip N N N N may be utilised for connecting
the nozzle F to the shaft H.
The shaft M is provided with reduced ends which rest in suitable bearings and
has at one end keyed or clamped to it a lever O, upon the free end of which is
an adjustable weight 0. The action of this weight on the lever O tends to turn
the rod M in its bearings, and forms an adjustment device for the purpose of
controlling the pressure at which the regulator hereinafter described is to come
into operation. This movement is arranged to be controlled by steam or other
pressure by means of the following device.
A casing P which may be conical or tapered as shown, is closed at one end by
a cover Q, and at the other by a plug R adjustably held by a screw cap R¹. The
cover Qis bolted to the flange Pi, after a thin metal diaphragm S has been laid
over the end of the casing P. In order to hold this diaphragm a small distance
away from the face of the cover Q, a packing ring S preferably of paper is inserted
as shown in Fig. 2 and the cover bolted on. Within the casing and against. the
diaphragm S is a plug Swhich acts as a piston-being-a-loose-fit-within-the-end.
of the casing P. The space between the diaphragm S and the face of the cover Q
is in communication through a pipe Q with some source of steam pressure. A
metal spring bar (T is provided at its ends with knife edges T placed slightly
out of the centre and carried in notches in the plug or piston S2 and the plug R.
About the centre of this bar T is situated a collar T provided with a screw-
threaded hole into which is screwed the end of a rod T3 is such a manner as to
clamp the collar T upon the bar T. The free end of the rod T is provided with
an eye T with which engages a stud 02 upon one side of the lever O.
The operation of the above described device is as follows:-
Assuming the burner to be supplying heat to a steam boiler, if the pressure in
the boiler exceeds a predetermined limit, to which the strength of the spring
bar T is adjusted the pressure of steam in the space between the diaphragm Sand
the face of the cover Q, which is in communication with the boiler through the
pipe Q', causes the diaphragm to move slightly away from the cover, in so doing
moving the plug S2 and bending the rod T in an upward direction. The latter
will impart a turning movement through the lever Ù to the rod M, which will
result in the needle K being forced into the nozzle and the flow of vapour and
consequently the flame reduced. As soon as the steam pressure in the boiler falls
sufliciently the parts return to their normal position and the flame increases.
pro-
In order to enable the movement of the needle K to be limited à bracket U,
which may form one of the bearings of the rod M is provided with arms U U
which lie above and below the lever O. The arms carry set screws U³ U
vided with lock nuts by means of which the amount of movement of the lever O
can be regulated. An additional set screw U is also provided in the lower
arm U¹, this screw having a milled head in order to enable it-to be readily turned
by the fingers, its object being to allow of the lever 0 being forced up so as to
push the needle into the nozzle when starting the burner in order to check the
initial rush of vapour.
If the lever O is arranged as it conveniently may be, to project on the other
side of the shaft M, the set screw Us is situated on the upper arm of the supporting
bracket U, in which case it is-preferably provided with a spring to prevent it from

page_text: shaking down into an operative position when not required. The bracket U may
conveniently be bolted to the casing P as shown in Fig. 1.
In order to allow of the adjustment of the plug R the cap R¹ is provided exter-
nally with notches R2, with which engages a spring R³, so that the cap may be
readily moved and securely locked in the required position.
The bar T is preferably formed flat of rectangular cross section, but it is obvious
that other forms of bar may be employed if desired.
It is to be noted that by means of the above-described regulator a very slight
end movement is required in order to bend the bar T, a largely multiplied move-
ment being obtained from the deflection at the centre.
If desired a regulating device constructed on the same principle may be
employed to control the flow of oil to the vapourizer. Such a device is illustrated
in Fig. 5 in which P is a casing similar to that shown in Figs. 1 and 2 being
provided with a bar T, plugs R and S2 and diaphragm S the back of which is
exposed to steam or other pressure.
About the centre of the casing P are formed two bosses into which pass the
ends of tubes P3 P3, the oil entering the casing by the former and leaving it
by the latter to pass to the vapourizer. At the entrance of the tube P³ is formed
a valve seat P4 for the reception of a conical valve T3 which is carried upon a
short rod T attached to the collar T upon the bar T. The collar T2 may be
either fixed upon the bar or loose in which case suitable guides are provided
for the valve T
The valve T is normally held off its seating, the oil being allowed to pass
freely through the casing P on its way to the vapourizer, but if the pressure, say
in a steam boiler heated by the burner, exceeds a predetermined limit, to which
the bar T has been adjusted, the latter is deflected and the valve T brought
down on to its seating," whereby the flow of oil is checked. Upon the pressure
falling the valve is returned to its normal position and the oil once more allowed
to pass freely. Suitable stops may be arranged within the casing in order to
ensure the deflection of the bar T in the proper direction.
The above forms an efficient means of automatically controlling the oil supply
without necessitating the use of stuffing boxes glands or the like, as all the moving
parts are enclosed in the casing P.
If desired more than one of these regulators may be employed either for con-
trolling the needles of the nozzle or for checking the flow of oil to the vapourizers
where a series of burners are in operation. In this case each regulator may be
arranged to come into operation at a different pressure from another so that as the
pressure rises the burners may be shut off one after another or in sets as required.
In the form of burner illustrated in Fig. 6, the vapourizer tube D is arranged
almost horizontally, the nozzle F being situated so as to direct the stream of
vapour into the open end of a burner tube V of suitable cross section. One end
of the tube V is closed while the other end, into which the nozzle opens, is pre-
ferably slightly flared. Transverse saw-cuts VI are made upon the upper side of
the tube. The vapour issuing from the nozzle F passes into the tube V and
emerges through the saw-cuts VI where it is ignited, the sheet of flame passing
around the vapourizer D. The nozzle is provided with a needle K carried on a
rod L which is adjustable in the manner previously described. If desired the
tube V and the nozzle F may be arranged to be relatively adjustable, so as to
allow of more or less air being drawn in at the flared end of the former.
It has been found that in a burner of the above described type, if the oil supply
is turned on before the vapourizer is sufficiently heated, the fuel issues through
the nozzle in a liquid state instead of in the form of vapour. To prevent this the
device illustrated in Fig. 7 may conveniently be employed. A pocket W is formed
upon or arranged in immediate connection with the vapourizer. The pocket is
formed of larger diameter at the bottom than at its mouth and is filled with some
fusible material X. The cock which controls the supply of fuel is preferably of
a screw-down type, the valve spindle Y being extended with its end resting in a

page_text: bearing (not shown in the drawings) conveniently carried by the vapourizer D.
Keyed upon the valve spindle is a hand lever Y¹ and a lever Y³, the latter having
loosely attached to its free end a plunger Y which fits loosely within the pocket W.
The end of the plunger Y preferably carries circular grooves Y. It will thus
be seen that it is impossible to move the lever Y and open the cock, controlling
the supply of liquid fuel, until the vapourizer and consequently the pocket W has
been heated sufficiently to fuse the material X, and allow the plunger Y3 to be
withdrawn.
It is to be noted that in the burner shown in Figures 1 and 2 a single nozzle F
has been described as being carried on the tube H, but it is to be understood that
the latter may conveniently carry any number of these nozzles, the corresponding
needles being controlled by the movement of the regulating bar T operating upon
the shaft M in the manner above described. Similarly in the burner shown in
Fig. 6 several nozzles F and tubes V may be arranged side by side.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In an oil or similar burner a double-purpose needle such as K one portion
whereof is employed for regulating the flame and another portion for cleaning
out the nozzle opening.
2. In an oil or similar burner the combination with the nozzle of a needle such
