Engineer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to arrange the apparatus for burning liquid fuel
in such a manner that the combustion may be more perfect and so accomplish a
more economical use of liquid fuel. The way in which I accomplish this is as
follows I have an injector or valve of a cylindrical or other suitable form, in the
outer case of which I have an opening and branch pipe for the admission of
the steam and another opening & branch pipe for the admission of the liquid fuel.
These are connected with the steam boiler and with the liquid fuel reservoir or
tank with suitable pipes and cocks to regulate or cut off the supply of liquid fuel
or steam.
.
Inside of the outer case I have a hollow plug with apertures to allow the
entrance of fuel from one of the branches. Towards the end of the hollow plug
I have a mitre which closes on a corresponding mitre on the case. By a sufficient
opening this allows the steam to flow through its branch around the outside of the
hollow plug through the mitre valve. Near the same place there is a mitre within
the hollow plug which is opened or closed by a mitre on a rod passing down the
axis of the plug. On the hollow plug there is a screw which works into a corre-
sponding screw in the outer case & by turning a handwheel on the end of the
bollow plug it is moved to open or close the valve on the end thereof and thus
regulating the amount of steam supplied. In the same way there is a handwheel
on the end of the internal rod which rod having also a screw working into a
corresponding screw in hollow plug. When this handwheel is turned the mitre
valve on end thereof is opened to the necessary amount to give sufficient flow to
the liquid fuel as may be desired. The conical or mitre surface at the end of the
rod is continued outwards to give direction and to spread the flowing liquid, &
corresponding to this conical surface there is a hollow cone at the end of the outer
case so that the liquid fuel & the steam flow outwards in an expanding conical
sheet Outside of this there are also hollow concentric cones for the admission of

page_text: air so as to facilitate the flow of air by thus inducing a current so as to thoroughly
comingle and incorporate the air with the outflowing liquid fuel and steam. The
cones for the flow of the air are adjustable to the requirements of the fuel supplied,
or the air may be brought into contact with the fuel in any other way that may be
preferred. The outer case is divided into two parts by a stuffing box which is
between the steam branch and the liquid fuel branch. This is to prevent the
steam forcing its way back into the liquid fuel supply.
The branch for the liquid fuel supply and the branch for the steam supply may
be reversed from fuel to steam & from steam to fuel supply.
There may be a small pipe leading from the steam to the fuel supply so as to
convey away any deposit from the liquid fuel when necessary.

I THOMAS SMITH of 23 Huddleston St Cullercoats Northumberland Marine
Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS FOR BURNING LIQUID FUEL FOR STEAM BOILERS AND OTHER
PURPOSES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to arrange the apparatus for burning liquid fuel
in such a manner that the combustion may be more perfect and so accomplish a
more economical use of the liquid fuel. The way in which I accomplish this is as
follows. I have an injector or valve of a cylindrical or other suitable form. In
the outer case of which I have an opening and branch pipe for the admission of
the steam and another opening and branch pipe for the admission of the liquid
fuel. One is connected with the steam boiler and the other with the liquid fuel
reservoir or tank with suitable pipes and cocks to regulate or cut off the supply
of liquid fuel or steam.
Inside of the outer case I have a hollow plug with apertures to allow the
entrance of fuel from one of the branches. Towards the end of the hollow plug
I have a mitre which closes on a corresponding mitre on the case. By a sufficient
opening this allows the steam to flow through its branch around the outside of the
hollow plug through the mitre valve. Near the same place there is a mitre within
the hollow plug which is opened or closed by a mitre on a rod passing down the
axis of the plug. On the hollow plug there is a screw which works into a corre-
sponding screw in the outer case and by turning a handle on the end of the hollow
plug it is moved to open or close the valve on the end therof and thus regulating
the amount of steam supplied. In the same way there is a handle on the end of
the internal rod, which rod having also a screw working into a corresponding
screw in the hollow plug. When the handle is turned, the mitre valve on end
therof is opened to the necessary amount to give sufficient flow to the liquid fuel
as may be desired. The conical or mitre surface at the end of the rod is continued
outwards to give direction and to spread the flowing liquid, and corresponding to
this conical surface there is a hollow cone at the end of the outer case so that the
liquid fuel and the steam flow outwards in one or more expanding conical sheets.
Outside of this there are also one or more hollow concentric cones for the admission
of air so as to facilitate the flow of air by thus inducing a current so as to
thoroughly pulverize the oil & thus comingle and incorporate the air with the
outflowing liquid fuel and steam. The cones for the flow of the air are adjustable
to the requirements of the fuel supplied, or the air may be brought into contact
with the fuel in any other way that may be preferred.
The outer case is divided into two parts by a stuffing box which is between the
steam branch and the liquid fuel branch. This is to prevent the steam forcing its
way back into the liquid fuel supply.

page_text: The branch for the liquid fuel supply and the branch for the steam supply may
be reversed from fuel to steam and from steam to fuel supply.
There may be a small pipe leading from the steam to the fuel supply so as to
carry away any deposit from the liquid fuel when necessary.
Fig. 1 of the accompanying drawing is a longitudinal section of the burner valve
or injector a, is the branch or opening for the supply of the liquid fuel in the part
of the outer casing 6 The liquid fuel flows into this outer casing from its reservoir
and thence through the orifices or slots c c c in the hollow plug d towards the end
of which it passes outwards through the mitre valve e where it is met and carried
forward and outward by the steam issuing from the mitre valve f. The steam is
supplied through a branch 61 of the outer casing and passing outside of the hollow
plug d and inside of the outer casing b¹ passes through the mitre valve falready
mentioned, where, meeting with the liquid fuel carries it outward to the furnace.
The shape of the valve on the end of spindle g deflecting the current outwards,
spreads it in an attenuated sheet when it is met by the inflowing induced current
of inflowing air through the conical ring h which ring is adjustable to the require-
ments of the burner by studs and slots h¹ or other means.
The mitre valve e for the supply of the fuel is regulated by spindle g which is
moved out or in by the handle g¹ being turned causing the screwed part of the
spindle g to move in the corresponding screwed part in hollow plug d.
is the gland and stuffing box to prevent leakage of fuel or steam.
The mitre valve f for the supply of steam is similarly regulated by the hollow
plug d being moved by causing its screwed parts to turn in the corresponding
screwed part in the outer casing b by means of handle d. j is the stuffing box and
gland for preventing the leakage of fuel or steam k is a gland and stuffing box for
preventing the steam driving back the liquid fuel into its reservoir and connects
the outer casing b with the outer casing 61. n is an opening if required for the
admission of air which would be drawn in along with the inflowing oil or
liquid fuel.
.
The steam supply is so arranged that there is no wire drawing so the full
pressure of steam can be maintained up to the mitre valve f. Atmospheric air for
combustion may be admitted to the furnace in any way that may be desired and
may be regulated by suitable valves.
Fig. 2 is a section at x x in fig. 1 shewing spindle g at that part with projecting
wings or guides so as to guide the valve on end of spindle to a true seat on
mitré e.
Spindle g may be in two parts and connected together with a pin m fig. 1
loosely fitting so as to give freedom of action.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st. The method of regulating and adjusting the various parts of the apparatus
for the effective pulverizing of the liquid fuel at the point of discharge.
2nd. The whole combination as substantially described.
