Year: 1880

page_text: LETTERS PATENT to Severin Borland, of the City of Manchester, in the County
of Lancaster, Mechanical Engineer, for an Invention of "IMPROVEMENTS IN
INJECTORS, OR APPARATUS FOR RAISING AND FORCING FLUIDS AND FEEDING
STEAM BOILERS."
PROVISIONAL SPECIFICATION left by the said Severin Borland at the Office
of the Commissioners of Patents on the 21st June 1880.
SEVERIN BORLAND, of the City of Manchester, in the County of Lancaster,
Mechanical Engineer. "IMPROVEMENTS IN INJECTORS, OR APPARATUS FOR RAISING
AND FORCING FLUIDS AND FEEDING STEAM BOILERS,"
The object of my Invention is to so construct an injector that the branches for
pipes bringing steam and water to and taking it from the injector need not be
disturbed when it is necessary to examine or clean out obstructions in the nozzles
or internal parts, and further, to so construct these internal parts that they may
be readily removed and replaced; and my Invention consists in an improved
combination, arrangement, and construction of the parts, formed by a hollow block
or casting, which has two junctions for union or flange joints in the same line, one
on one side, the other on the opposite block or casting; one junction is for the pipe
to bring water to the injector, the other to take the combined water and steam
away or to the boiler. This block or casting has also two other junctions on
opposite sides, one to bring the steam to the apparatus, the other for the casing or
cap, hereinafter described.
The block or casting is prepared to receive the steam nozzle, and in its interior
there is a division which separates the water coming to the steam cone or nozzle
from the combined steam and water (when it has passed through the nozzles) which
is passing to the branch connected with the boiler.
The division in the block or casting is also bored out to receive the large end of
the combining cone, which is formed with a shoulder to fit water tight in the hole.
The smaller end of the combining cone is prepared with a shoulder to fit a part
in which the receiving and discharging cone and overflow orifice is formed in one
piece, the receiving and discharging cone terminating and branching into two

cone or nozzle. The cavity for the overflow has a junction with one or two side
passages which unito together below the passages from the receiving cone, and at
this point there is or may be a valve opening outwards, or this valve may be in
the casing or cap, referred to hereinafter.
The outer end of the combined part, in which the receiving and discharging cone
and overflow orifice is formed, is bevelled to form a joint with a cap or casing,
which screws on to the branch of the block or casting hereinbefore mentioned, and
makes a joint with it, and, when so screwed up, it keeps the nozzles or cones in
their correct position. There is an annular space left between the cap or casing 1
and the exterior of the nozzles or cones, into which the combined steam and water
comes from the cross passages of the receiving and discharging cone, this annular
passage being thus brought in connection with the outlet branch of the block or
casting conveying the combined steam and water away or to the boiler.
The outlet for the overflow is in the end of the cap or casing in an axial line 1
with the cones or nozzles.

by the said Severin Borland in the Great Seal Patent Office on the 16th
December 1880..
SEVERIN BORLAND, of the City of Manchester, in the County of Lancaster,
Mechanical Engineer. "IMPROVEMENTS IN INJECTORS, OR APPARATUS FOR RAISING
AND FORCING FLUIDS AND FEEDING STEAM BOILERS.",
The object of my Invention is to 50 construct an injector that the branches for
pipes bringing steam and water to and taking it from the injector need not be
disturbed when it is necessary to examine or clean out obstructions in the nozzles
or internal parts, and further, to so construct these internal parts that they may be
readily removed and replaced; and my Invention consists in an improved
combination, arrangement, and construction of the parts, formed by a hollow block
or casting, which bas two junctions for union or flange joints in the same line, one
on one side, the other on the opposite side of the block or casting; one junction is
for the pipe to bring water to the injector, the other to take the combined water
and steam away or to the boiler. This block or casting has also two other
junctions on opposite sides, one to bring the steam to the apparatus, the other for.
the casing or cap, hereinafter described.
.
.
The block or casting is prepared to receive the steam nozzle, and in its interior
there is a division which separates the water coming to the steam cone or nozzle
from the combined steam and water (when it has passed through the nozzles) which
is passing to the branch connected with the boiler or other receiver.
The division in the block or casting is also bored out to receive the large end
of the combining cone, which is formed with a shoulder to fit water tight in the.
hole.
The smaller end of the combining cone is prepared with a shoulder, to fit a part
in which the receiving and discharging cone and overflow orifice is formed in one
piece, the receiving and discharging cone terminating and branching into two
passages or outlets at a right angle to the axis of the receiving and discharging
cone or nozzle..
The cavity for the overflow has a junction with one or two side passages, which
unite together below the passage from the receiving cone, and at this point there
is or may be a valve opening outwards, or this valve may be in the casing or cap,
referred to hereinafter.
The outer end of the combined part, in which the receiving and discharging cone
and overflow orifice is formed, is bevelled to form a joint with a cap or casing,
which screws on to the branch of the block or casting hereinbefore mentioned, and
makes a joint with it, and when so screwed up it keeps the nozzles or cones in their
correct position.
There is an annular space left between the cap or casing and the exterior of the
nozzles or cones, into which the combined steam and water comes from the cross
passages of the receiving and discharging conc, this annular passage being thus
brought in connection with the outlet branch of the block or casting conveying the
combined steam and water away or to the boiler.
The outlet for the overflow is in the end of the cap or casing in an axial line
with the cones or nozzles.
Fig. 1 is a longitudinal section; Fig. 2 is a view of the outside of the apparatus
taken at a right angle to section shown by Fig. 1, and with the screw and cone
spindle removed; Fig. 3 is a view of the outside at the steam cone end of the parts_
shown by Fig. 1, but with the cone screw spindle removed; Fig. 4 is a cross section
on the line A-B, Fig.-1; Fig-5-is a longitudinal section of the receiving cone part,
but taken at a right angle to the section shown in Fig. 1; and Fig. 6 is à cross
section taken at C-D. Fig. 1
.

page_text: The apparatus may be used with a cone screw spindle for regulating the steam
supply, or without it; in the latter case the steam is taken to the steam cone direct,
as illustrated by Fig. 2.
a is a part having four branches flanged or screwed, as shown; one branch a¹ is
bored out to receive the steam cone b, as shown, and there is a diaphragm or i
partition a³ in the middle of the part a, which is bored out to receive one end of
the combining cono c, as shown, the other end of which is turned to fit the end
of a part d, in which the receiving cone and overflow orifice and passages are
formed, and the lower end of this part is coned to fit a cone in a cap e screwed on
to one of the branches a³, as shown.
d' is the orifice for overflow which escapos along the passages (see Figs. 1 and
6), and can then pass out through a hole in the end of the cap e, which is or may be
closed against the admission of air by a valve f, having a short spindle f¹ to slide
in a hole formed in a part 2 screwed in the end of the cap e (as shown), the valve
being pressed against its seating by a spring surrounding the valve spindle f¹, the 1
escaping overflow passing away through passages formed in or small holes drilled
through the screwed part f³.
d³ is the receiving cone, which branches into two passages d' at a right angle to
it, and thus enters the space a (see Figs. 1 and 6) between the parts c and d and
the cap e, and passes away through the branch a to the pipe a³, conveying it?
away or to the boiler; as is the pipe, and a' the branch by which water is brought
to the apparatus.
When a cone screw regulating spindle is not used, as in Fig. 2, aª is the pipe, and
a the branch by which steam is brought to the apparatus, but when a screw cone
spindle is used, its casing his screwed on the branch a', as shown, and there is a
branch formed in this casing for the steam and the connecting pipo h³.

The cone spindle g is shown with a hole in its axis and a cross hole for steam,
as is well understood; h³ is the stuffing box, and h the hand wheel for turning
the cone spindle.
I have now particularly described the nature of my said Invention, and the 3
mode of carrying the same into effect, and claim as my Invention,-
Firstly. The combination, arrangement, and construction of apparatus for raising
and forcing fluids, substantially as hereinbefore described.
Secondly. The forming of the branches (a' and a') for water, and combined water
and steam, opposito and in a line with each other, substantially as bereinbefore
described and illustrated by the Drawings.
Thirdly. The construction and arrangement of the part forming the receiving
cone (d), so that the overflow is arranged to escape in a line with the longitudinal
axis of the receiving conc, substantially as herein before described and illustrated
by the Drawings.
Fourthly. The combination of a cap (e) with the cones or parts a and d,
substantially as hereinbefore described and illustrated by the Drawings.
In witness whereof, I, the said Severin Borland, have hereunto set my hand
and seal, this Fifteenth day of December, in the year of our Lord One
thousand eight hundred and eighty.
