Improvements in or relating to the Eurning of Inflammable Gas or
Vapour and in Apparatus therefor.
We, THOMAS CLARKSON, Engineer, and THE CLARKSON & CAPEL STEAM CAR
SYNDICATE LIMITED, both of Deverell Street, Great Dover Street, in the County of
Surrey, do hereby declare the nature of this invention to be as follows:
This invention relates to the burning of inflammable gas or vapour and in
apparatus therefor, and although otherwise applicabie, is particularly suitable for
burners in which a wide range of adjustment is required, and it will be hereinafter
described as applied to a burner suitable for burning oil vapour for heating
purposes.
A common form of such a burner comprises the burner proper which may be
of varied construction, and a vapouriser in which the oil is subjected to the action
of heat and the vapour led to the burner where, or before it reaches the burner,
it is mixed with air. Preferably the vapour is discharged through a nozzle into
an inducing tube, where it acts on the principle of an injector, by sucking in
air into a closed box forming part of the burner, the burner proper being composed
of openings of some description through which the inflaminable vapour mixture
passes to be burnt.
According to this invention the burner box comprises an inducing tube into
which the vapour is discharged, the tube opening into a chamber which forms
the under portion of the burner.
Upon the top of this chamber fits a cap, composed of a flanged plate with the
flange directed downwards, and portions cut out of the flange so that the cap
has the appearance of a circular plate with a series of fingers directed downwards
from its edge. These fingers divide up the inflammable vapour mixture issuing
from the burner into a series of radiating streams, the arrangement being such
that the quantity of inflammable mixture issuing from the burner can be varied
or completely stopped by raising or lowering the cap.
Above the burner and supported in some convenient manner is arranged a
vapouriser, which in one construction may be a simple coil of pipe arranged pre-
ferably conically so that the lowest coil is of smaller diameter than those above >
it. The fuel to be vapourised is led in at the lowest coil and the vapour conducted
from the uppermost coil to the inducing nozzle of the burner. In another con- .
struction the vapouriser may comprise a hollow body preferably of approximately
spherical form, having conducting ribs or projections formed upon its exterior.
This vapouriser is carried upon a suitable support which may be composed: of:
tubular members, or of one or more tubular members combined with one or more
solid members. The fuel to be vapourised is led through one or more of the
tubular members of the support to the vapouriser, the vapour being conducted by
a suitable pipe leading from the top of the vapouriser to the burner nozzle.
Around the top of the burner and carried on suitable supports are arranged one
or more preferably conical funnels or plates so situated that the flame from the

page_text: burner will impinge against their inner surfaces and be directed upwards. These
funnels become incandescent and act as a director, a radiator, a promoter of com-
bustion and an igniter in the event of the flame being momentarily extinguished.
The metal of which the funnels are composed is preferably perforated.
Where the vapouriser is formed of the conical coil of tube above described,
its dimensions are such and it is preferably so placed that the flame when deflected
from the funnels will not strike directly upon the vapouriser coil, but will rise
up around it. Where the spherical vapouriser is employed, it may if desired
also be arranged so that the flame does not directly strike against it.
The nozzle from which the vapour to be burnt issues into the burner box is
provided with a needle of some convenient construction, the end of which enters
the orifice of the nozzle and enables the flow of vapour therefrom to be controlled
by suitable movement of the needle. Conveniently the orifice of the nozzle is
formed rectangular, the extremity of the needle lying therein being chisel shaped.
With such an arrangement it is advisable to have the needle spring-controlled
so that the portion which lies in the nozzle is constantly pressed upwards or
downwards, as the case may be.. It has been found that by placing this controlling
spring so that it acts directly upon the needle when the latter is situated in the
inducing tube, owing to the heat developed by the burner the spring gradually
loses its temper; in order to obviate this a lever may be arranged within the
inducing tube, one end of this lever acting upon the needle while the other end
which lies near the open end of the inducing tube is acted upon by some con-
venient construction of spring. With this arrangement, the air which is con-
stantly entering the open end of the inducing tube, keeps the spring cool and
prevents its deterioration.

Improvements in or relating to the Burning of Inflammable Gas or
Vapour and in Apparatus therefor.
We, THOMAS CLARKSON, Engineer, and THE CLARKSON & CAPEL STEAM CAR
SYNDICATE LIMITED, both of Deverell Street, Great Dover Street, in the County of
Surrey, 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 the burning of inflammable gas or vapour and in
apparatus therefor, and although otherwise applicable, is particularly suitable for
burners in which a wide range of adjustment is required, and it will be hereinafter
described as applied to a burner suitable for burning oil vapour for heating
purposes.
A common form of such a burner comprises the burner proper which may be
of varied construction, and a vapouriser in which the oil is subjected to the action
of heat and the vapour led to the burner where, or before it reaches the burner,
it is mixed with air. Preferably the vapour is discharged through a nozzle into
an inducing tube, where it acts on the principle of an injector, by sucking in
air into a closed box forming part of the burner, the burner proper being composed
of openings of some description through which the inflammable vapour mixture
passes to be burnt,

page_text: Figure 5 is a plan of the same:
Like letters indicate like parts throughout the drawings.
A burner constructed in accordance with this invention comprises a burner box
or mixing chamber A, one end, of which A¹ is slightly flared and has situated
within it a jet nozzle B. The other end of the burner box is turned up as at A
preferably at right angles to the main part of the box and has fitting on its open
end a lid or cap. C. The latter may conveniently be slightly dished and has a
downwardly directed flange around its edge, this flange being cut away in places
so as to form fingers or projections C. These fingers C, when the cap C is in
place upon the burner, lie outside the wall of the burner box and serve to guide
the lid when it is raised or lowered for the purpose of regulating the amount of
rapour issuing from the orifices between the fingers. The lid is provided with
a covering of refractory material (2, and is carried on the end of a spindle 1),
the other end of which projects through the wall of the burner box A. A
pocket A is formed near the end A' of the burner box, and a rod E runs transversely
through this pocket being carried in a rotatable manner in bearings formed by the
side wall of the pocket. Upon the portion of this rod E which lies within the
pocket A³ is keyed a lever F while upon the part which projects from the pocket A
is keyed another lever G. The lever F carries pivotted to its upper end a regula-
ting bar or needle H of rectangular cross-section one end of which H¹ is bevelled
or chisel-shaped and adapted to lie within the rectangular orifice of the nozzle B.
A lever pivotted at J has one end suitably connected to the lower end of the
spindle D and the other end slotted as at J2 and in engagement with a pin G¹
carried upon the free end of the lever G. It will thus be seen that by means of
the levers E G J and the spindle D the lid C can be raised or lowered and the
regulating bar H moved in or out of the nozzle B simultaneously, some convenient.
form of automatic regulator being preferably used to effect this movement, though
it may be brought about by hand if desired."
In order to keep the end of the regulating bar H constantly pressed against
the lower side of the orifice of the nozzle B, spring pressure is exerted on the
tail H of the bar H, and in order to prevent the temper of the spring used from
being effected by the heat developed in the burner box a lever K is employed
pivotted at K one end K2 of this lever bearing against the end I of the regulating
har H, while the other end K³ is acted upon by a spring L which is situated outside
the burner box and acts so as to exert a pull upon a rod L₁ the end of which
engages within the burner box with the end K of the lever K. The end of the
burner box behind the nozzle B is provided with air inlets M, which are controlled
by a rotary perforated disc M¹ on the principle of a hit-and-miss ventilator.
Brackets Nattached to the part A2 of the burner box support one or more conical
funnels or plates 0, formed of suitable metal and perforated. The funnel 0.
shown in Figure 1, is provided with inwardly projecting ribs 0', notched or recessed
to receive and support the coils of a tube Q which constitutes the vapouriser.
The funnel O is so situated in relation to the burner orifices that the flame, will
he deflected upwards around the coil Q which is preferably formed conical. One
end of the pipe Q is connected to a fuel supply tank and the other end to the
nozzle B.
In the arrangement illustrated in Figure 3 the vapourising coil Q is replaced
by a vapouriser in the form of a spherical body Q', provided with ribs or gills Q
This vapouriser is supported at its lower end by and is in communication with
tubes P P which take the place of the brackets N, being secured in lugs A+ formed
on the part A2 of the burner box. The tubular supports P P carry in this case
iwo funnels of the kind previously described and arranged at an angle to each
other as shown in Figure 3. Conveniently the fuel is supplied to the vapouriser Q
through one or both of the tubular supports; a pipe P2 which forms a connection
with a supply tank is shown in the drawing as being connected to the lower end
of the pipe P¹. The vapour is led by a pipe Q³ to the nozzle B of the burner.

page_text: The supports P P1 may if desired be made solid instead of hollow, the fuel being
led to the vapouriser Q¹ by a separate pipe.
Figures 4 and 5 illustrate a modification of the radiating plates. In this
construction a funnel is built up of segmental plates 02, each provided on its
upper face with a series of projections 0³ disposed between perforations 0¹. Each
plate has a flange 05 by which it is attached to one of the brackets N by a
bolt 06.
It is obvious that the fingers C¹ for dividing up the flame and guiding the lid
when moved may equally well be formed on the burner box around the orifice,
the lid lying between them.
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

1. In an oil, vapour or similar burner the combination with the burner box or
its lid of dividing fingers such as C₁ whereby the sheet of flame issuing from
