A Split Spray Liquid Fuel Injector, for the Purpose of Injecting
and Burning Liquid Fuel in the Furnaces of Boilers or other
Furnaces or Fire Boxes.
I, HARRY VAUGHAN RUDSTON READ, of Broad Street Avenue, Blomfield
Street, in the City of London, Engineer, do hereby declare the nature of this
invention (a communication to me from John J. Impett, of Lima, Peru, Engineer,)
to be as follows :-
The invention has for its object a simple, cheap and efficient construction of split
spray liquid fuel injector for the purpose of injecting and burning liquid fuel in
the furnaces of boilers or other furnaces or fire boxes.
The body of the injector is of cast metal and is formed with two superposed
passages extending from the rear end to the head thereof, the upper passage is for
oil, the lower for steam; these passages are provided with screw nozzles or other
means of connection with the steam and oil supplies. The head of the injector is
preferably of circular form and it is made with an inclined or conical seat and
central block or solid portion to receive a cap which is held down to the body of
the injector by a central screw. The oil and steam passages in the head are of
segmental annular form and are located on opposite sides of the centre thereof.
The oil space which is around the rear portion of the head communicates with a
like shaped space formed in the cap, and the oil issues through an outlet or mouth
in the front of the cap. The segmental annular steam space in the head of the
injector body communicates with an upwardly directed segmentally conical emission
slit formed partly by the front portion of the cap seat and partly by the lower front
portion of the underside of the cup. A lip or guard is formed around the cap a
short distance above the steam emission slit.

A Split Spray Liquid Fuel Injector, for the Purpose of Injecting
and Burning Liquid Fuel in the Furnaces of Boilers or other
Furnaces or Fire Boxes.
I, HARRY VAUGHAN RUDSTON READ, of Broad Street Avenue, Blomfield
Street, in the City of London, Engineer, do hereby declare the nature of this
invention, a communication to me from John J. Impett of Lima, Peru, Engineer,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The invention has for its object a simple, cheap and efficient construction of
split spray liquid fuel injector for the purpose of injecting and burning liquid fuel
in the furnaces of boilers or other furnaces or fire boxes.

page_text: The invention is illustrated in the accompanying drawings in which Fig. 1 is a
longitudinal section, Fig. 2 a plan with the cap removed, Figures 3 and 4 opposite
end views and Fig. 5 a cross section of the improved liquid fuel injector and Fig. 6
is an underside view of the cap of same separately.
The body A of the injector is of cast metal and is formed with two superposed
passages ab extending from the rear end to the head c thereof, the upper passage a
is for oil, the lower b for steam; these passages are provided with screw nozzles a¹ b¹
or other means of connection with the steam and oil supplies. The head c of the
injector is preferably of circular form and it is made with an inclined or conical
seat and central block or solid portion c³ to receive a cap c3 which is held down
to the body of the injector by a central screw d. The oil and steam passages a³ b
in the head c are of segmental annular form and are located on opposite sides of
the centre thereof. The oil space a' which is around the rear portion of the head c
communicates with a like shaped space a' formed in the cap c and the oil issues
through an outlet or mouth a in the front of the cap c. The segmental annular
steam space in the head of the injector body communicates with an upwardly
directed segmentally conical emission slit e formed partly by the front portion of
the cap seat and partly by the lower front portion of the underside of the cap c³.
A lip or guard f is formed around the cap a short distance above the steam emission
glit e.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim 1s
1. In a split spray liquid fuel injector a space a for liquid fuel above a space
for steam, which join with and pass through other spaces in the cap c substantially
as shown and described.
2. In a split spray liquid fuel injector a slit e for steam formed by the joint of
the cap with the head c underneath an oil outlet or mouth at formed in the cap c'
substantially as shown and described.
3. In a split spray liquid fuel injector, a cap c³ secured to the head c of the
body A which cap has an oil space as joining with and corresponding to the oil
space a² of the head c of the body A making with a part of the joint on the head c
of the body A, the steam slit e also a lip above the slit e substantially as shown
and described.
4. In a split spray liquid fuel injector the arrangement of the oil and steam
spaces a. b. a 63 in connection with the cap substantially as shown and described
and for the purposes set forth.
5. A split spray liquid fuel injector constructed substantially as herein shown and
described.
