Improvements in Apparatus for the Lateral Action or Induction
of Fluids.
We, ALEXANDER MORTON, Engineer, of 241, West George Street, Glasgow, Lanark
shire, and WILLIAM RICHARD MIDDLEMORE Tuoмson, Engineer, of 96, Buchanan
Street, Glasgow, aforesaid, do hereby declare the nature of our invention to be as
follows:
"
This Invention relates to improvements in and connected with apparatus of the
character known as Ejector Condensers," and Injectors and Water Lifters" for
which Letters Patent were granted to the present first named applicant No. 21067,
and No. 456. The present improvements consist chiefly in so arranging and com-
bining the nozzles that a less quantity of water is required to efficiently condense
a given weight of steam, or that water at a higher temperature may be used with
like results; and this invention has for its object to make these apparatus work
satisfactorily where the inlet cold water is limited, or where it may be of too high a
temperature for existing apparatus, and in arrangements for governing the engine,
or the admission of steam to the cylinders driving the pumps for these apparatus.
The improvements consist first in constructing the lateral action nozzle apparatus
of the Ejector Condensers, or Injectors and Water Lifters with a series of jets or
Dozzles which may be parallel with each other within a single outer case, the inlet
nozzles and their respective induction nozzles or tubes of each set being concentric
or in line with each other. These nozzles and induction delivery tubes may be
fitted into two fube plates secured within the outer case and bored exactly con-
centric, the former into the first or inlet tube plate, and the latter into the second
or delivery tube plate. The chamber above the first tube plate forms the inlet
water branch and chamber, and the chamber between the tube plates forms the
steam inlet and vacuum chamber. And within this chamber. between the inlet
nozzles and the throat of the induction tubes, one, two, or more guide nozzles may be
fitted for each jet, and the whole may be enclosed within the fluid tight outer casing
with the necessary inlet and outlet branches formed thereon.
The lower chamber
below the induction delivery tubes, forms the delivery water chamber with discharge
branch. In cases where centrifugal, screw, or other revolving pumps may be used to
impel the water through the apparatus, they are connected with the inlet water
branch or chamber above the first nozzle plate, so that the greater the speed at which
they may be driven the greater proportional pressure in that chamber, consequently,
if a small cylinder and piston diaphragm, or other equivalent, be connected with that
chamber and the throttle or other steam valve of the main engine, the former may
govern the latter so as to act against a re-acting spring or equivalent weight and
maintain a nearly constant speed of the engine driving the pump, and so regulate any
desired uniform pressure and quantity of water supplied to the condenser.
improvements in the Injectors consist in so carrying and combining the nozzles in
one straight line through the centre of the apparatus that they may form a complete
apparatus having two or more distinct converging combining nozzles with a separate
overflow chamber and passage behind each, and so that two or more distinct steam
branches may be governed by fixed and loose valves preferably on the same spindle
the one opening after the other as required.
The
It will be understood that either live or exhaust steam may be used and that the
first steam nozzle may be either a central steam jet within an annular water jet or
rice rere, in either Ejector Condensers," "Injectors," or other lateral action
induction fluid apparatus.

Improvements in Apparatus for the Lateral Action or Induction
of Fluids.
We, ALEXANDER MORTON, Engineer, of 241, West George Street, Glasgow, Lanark-
shire, and WILLIAM RICHARD MIDDLEMORE, THOMSON, Engineer, of 96, Buchanan
Street, Glasgow, aforesaid, do hereby declare the nature of our said Invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement in writing, reference being had to the accompanying
Five Sheets of Drawings, and to the letters and figures marked thereon, that is
to say:
Our said Invention relates to and comprises improvements in and connected with
apparatus of the character known as Ejector Condensers" and "
Injectors and
"Water Lifters" of the jet nozzle construction for the lateral action or induction and
eduction of the fluids employed, for which Letters Patent were granted to one of the
present applicants No. 2106 July 18 1867 and No. 456 Feb. 15 1869.
The present
improvements consist chiefly in so arranging and combining the nozzles that a less
quantity of water is required to efficiently condense a given weight of steam, or that
water at a higher temperature may be used with like results; and the invention has
for its object to make these apparatus work satisfactorily where the inlet water is
limited, or where it may be of too high a temperature for existing apparatus; and
comprises also improved arrangements for governing the engine, or the admission of
steam or other pressure fluid to the cylinders driving the pumps for supplying these
apparatus with water.
And in order that our said Invention and the manner of performing or carrying the
same into effect or practice may be properly understood, we have hereunto appended
five explanatory Sheets of Drawings, in which the same reference letters are used to
indicate corresponding parts in all the Figures where shown.
..
"
Figures and 2 on Sheet 1 are a sectional elevation and a plan, respectively, both
partly in section, as taken on the irregular lines 1-1 and 2-2 ou the opposite
Figures, of one construction or combination of the parts of an Ejector-Condenser
or nozzle lateral-action water-jet steam condenser, for producing a vacuum in and flow
of the steam or other fluids from the cylinders of steam engines or other vessels, all
in accordance with the improvements of our invention, with a number of sets of water
nozzles a ranged over sets of combining steam and water nozzles b, c, and discharge
lateral acting trumpet tubes d, d, each set of these nozzles and tubes a, b, c, d, being
ranged concentrically or in line over each other, showing also one arrangement for
regulating the admission of steam to the cylinder of the engine, and governing the
speed of the engine or pump supplying the water to the apparatus. Figures 3 and 4
on Sheet 2, show a vertical section and a horizontal section taken on the lines 3–3
in the opposite Figures respectively, of another modification or arrangement and
combination of the parts of our Ejector-Condenser." slightly different from that
shown in Figures 1 and 2, in which regulating spindles e are fitted for the admission
of the water through the water nozzles, but no intermediate combining nozzles bare
fitted or shown. Figure 5 on Sheet 3 is a sectional elevation of an arrangement of
Ejector-Condenser" very similar to that shown in Figures 3 and 4. but shown
with hollow regulating nozzle spindles e, fitted through the water nozzles a and with
intermediate combining nozzles b. Figure 6 on Sheet 4 is a sectional elevation, and
Figure an inverted horizontal view, and Figure S a horizontal section as taken on
the lines 4 and 5-5 Figure 6, of an arrangement of our“ Ejector-Condenser
with a single concentric set of water and combining nozzles. two intermediate com-
bining water and steam nozzles b. b', in this case being shown as fitted between the
water nozzle a and the lower combining delivery nozzle e leading to the trumpet d, dễ.
This arrangement is also suitable as a water lifter. Figure on Sheet 5 shows a
sectional elevation of one construction or arrangement and combination of the parts
our

page_text: of steam nozzle Injectors, for feeding water into steam boilers, and Figure 10 is a plan
of the same, and Figures 11 and 12 horizontal sertions as taken on the lines G-G
and -7 in Figure 9, all in accordance with our improvements as applied to
Injectors.
Referring to Figures 1 and 2 of these Drawings:-The improvements of our
invention consist, first, in constructing the lateral-action nozzle apparatus of the
Ejector-Condensers," with a number or series of sets of water jets or streams and
their inlet and induction or combining delivery nozzles a, b, c, and tubes d, all fitted
parallel with each other (whatever number of these jets and sets of nozzles are used)
within a single outer case E, E, the inlet nozzles, and their respective induction
combining nozzles b, c, and delivery tubes of each set being always fitted concentric
or in line with each other. The inlet water nozzles, and induction delivery tubes c, d,
are or may be fitted into two tube plates or webs A, B respectively, secured within
the outer case E E', and bored exactly concentrically, dividing the case into a close
vacuum or induction steam chamber E, and an eduction or discharge pressure close
chamber E, the former inlet nozzles a being fitted into the first or inlet tube plate A
at a', and the latter delivery tubes into the second or delivery tube plates B at ".
The chamber A', preferably formed in the top or cover A, A', of the case E, E, above
the first tube plate A, forms the inlet water branch A2 and chamber A' of the apparatus,
and the chamber E between the tube plates A, B, forms the steam inlet and combining
condensing and vacuum chamber, with steam inlet branch E². The inlet water
branch A, or pipe leading to it, would be fitted with a stop valve or other equivalent
to shut off and put on the water to the chamber A¹; and when desired inlet check or
self-acting valves might be fitted in the inlet steam branch or branches E. And
within this chamber E between the inlet nozzles a, and the throat nozzle e, of the
induction or eduction delivery tubes d, one, two, or more intermediate guide nozzles b
(or b, b) are fitted and screwed at for each water jet and its nozzles a; and the
whole are enclosed within the fluid-fight outer casing E, E', with the necessary inlet
and outlet branches E², E³, respectively formed thereon. The arrows show the
direction of the flow of the water and steam through the apparatus. The lower
chamber E below the induction or eduction delivery tubes & forms the delivery water
chamber with its discharge branch E3, which would be connected by pipes to lead the
water to the lowest delivery level possible. In this arrangement, each water nozzle w
is shown as screw jointed at a into the disc or plate A of the cover water chamber A.A
and the combining water and steam nozzle b is shown as screwed to a ring and
feathers at ², on the lower part of the water nozzle a, and each combining discharge
nozzle e is here shown as formed on the inner throat end of its discharge trumpet d.
where it is screwed at into the plate B, which is jointed and screwed at 13 to an
annular flange formed in the inside of the case E E all these parts being turned
and faced, and the nozzles of each set bored and fitted so as to be concentric or in
line with each other: and all of a curved conoidal form contracting towards the point
in the direction of the flow of the fluids in the apparatus, the points of the nozzles
generally entering the nozzle in front, so as to make the outer surrounding nozzle an
annular nozzle in the condensers and water lifters, and in all cases the one fluid
assists by its lateral action to impel the other forward through the nozzles a, b, c,
into and through the discharge trumpet or expanding pressure tube, each with a
slightly increasing size of nozzle in the direction of the current. The action of
the apparatus is as follows:-The water being admitted to the chamber A flows
through all the nozzles a in solid central jets, and through their combining nozzles b. r.
and trumpets d d respectively: and the exhaust steam from the engine or other
vessel entering by the branch Emeets the jet of water in the combining nozzles b, c.
and is condensed, producing a vacuum in the chamber E and cylinders of the engines
connected therewith, the speed of the jet of water falling into the vacuum with
sufficient force from each nozzle a as to force the condensed steam or air or gas along
with it through the nozzles b, c, and delivery trumpet tubes d, e, into the chamber Ei,
all as indicated by the arrows in Figure 1. In cases when centrifugal, screw, or other
force pumps are to be used to impel the water through the apparatus, they are

page_text: connected with the inlet water branch A and chamber A above the first nozzle plate A,
so that the greater the speed at which they are driven, the greater would be the
proportional pressure of the water in the chamber A', consequently, if a small cylinder
and plunger or piston be fitted to this chamber A', or pipes leading thereto, as shown
at A, A, (or it might be a diaphragm or other equivalent), and have the throttle or
other inlet steam valve of the steam engine driving the pump connected by a rod to
this piston A, acting against the power of a re-acting spring or equivalent weighted
lever, so as to regulate the opening or closing of the throttle or other equivalent inlet
steam valve, and thus maintain a nearly constant speed of the engine driving the
pump, and so also regulate any desired uniform pressure and quantity of water
supply to the condenser, and preferably fitted with a stand pipe or air vessel to give
this uniform pressure.
an annular
Referring to the arrangement of this new multiple nozzle Ejector-Condenser "
shown in Figures 3 and 4, each water nozzle a is shown as fitted by flanges and serew
pins or studs at a', to the furned and bored top plate A of the water chamber A', and
have each a regulating centre spindle e fitted in them, secured to arms c¹ above,
projecting from a boss cottered or otherwise secured at el to the central spindle * of
the set. This central spindle is passed up through a stuffing-box at A" in the upper
end of the water chamber A', and shown as actuated by a hand screw and wheel
outside at A, which according as turned raises or lowers the central spindle, to
raise or lower the star armed crosshead e', c", and all the outer spindles e in their
respective water nozzles to regulate the emission of the jet of water at the point a
of the nozzles and spindle c. The regulating point of each spindle e is preferably
guided at its lower end concentrically to the nozzle point through
ring with vanes at a³ in each nozzle a, which vanes prevent the twisting or swirling
of the jet of water within the nozzles «, «². In this arrangement there are no inter-
mediate combining nozzles b, the jet of water being delivered direct from the water
nozzle a, a, of each set, into its throat nozzle c, which in this case is shown as
formed separate from the throat of its delivery trumpet d, d', and each jointed by
screw pins at el to a separate plate B₁ above the plate B to which the trumpets & are
shown as jointed by screw bolts at ", leaving a separate vacuum chamber E' below
the vacuum chamber E and above the discharge chamber E, and to which the tube
of the vacuum gange is generally attached at E. As shown in Figure 3, the case E E¹
may be formed in two parts jointed together by flanges and screw bolts at E" to
embrace the plate B to which the delivery trumpet tubes d are secured; or when the
case is formed in one piece this plate B may be bolted to the underside of an inner
flange at B similar to the upper plate B", and in some cases screw valves & might
be fitted through the lower cover E of the lower chamber E' opposite the lower
open end of each trumpet d, so as to be able to shut off any of these when desired,
and also shut off the water nozzle of the same trumpet by its spindle c. The action
and direction of the fluids through this apparatus is as indicated by the arrows, and
the water is admitted by the branch A³ to the upper chamber A', and the exhaust
steam is admitted by the branch E to the vacuum chamber E, which meeting the
water in the combining nozzle is condensed and forms a vacuum behind it in the
chamber E, and the cylinders of the engine connected to it, the water of condensation
and air or gases being forced out through each set of nozzles e and its lateral action
discharge trumpet d, d¹.
Referring to Figure 5 on Sheet 3, th's shows an arrangement of our multiple nozzle
condenser, analogous to that shown in Figures 3 and 4, but fitted with intermediate
combining nozzles b, secured concentrically by screw pins or studs to a ring and
feathers at on the lower end of each water nozzle . and having the spindles e
of the outer ring of nozzles « formed hollow, open at their upper and lower
ends, and actuated by the star armed crosshead secured to a solid central
spindle The upper ends of the hollow spindles work up through stuffing-
boxes in a plate A jointed between the top of the water chamber A', and
a second top chamber G, which may either have exhaust steam admitted to it by the
branch G', or live steam by the branch pipe ", or water by the branch of a higher

page_text: pressure than the water admitted by the branch A² of the water chamber A'. Each
of the branches G', G", and G, or the pipes leading to them, would have cocks or
screw valves on them, to admit either the steam or water to the chamber G as found
convenient or desired. The spindle is fitted to work up through stuffing boxes e","
in the lower and upper ends of the chest G, so as to be actuated outside at top, by a
hand screw and screw wheel at working up through a crosshead secured to
standards on the top of the chest G, so as to raise and lower the whole of the hollow
spindles e, and regulate an annular flow of water through each water nozzle a, and
combining nozzle 6, while admitting either a central jet of live or exhaust steam, or
it might be water of a high pressure through the lower end e*, of the central spindle
to increase the velocity of the water jet through the water nozzles a and combining
nozzles b and c, to inject this and the condensed steam from the engine and chamber E
through the lateral action delivery trumpets d into the vessel E', and out through the
discharge branch or E, against the pressure of the atmosphere, all as indicated
by the arrows, and otherwise substantially as described in reference to Figures 1
to 4.

The
Referring to the condenser or lateral action nozzle apparatus shown in Figures G
to 8 on Sheet 4 of the Drawings, this shows an arrangement either suited for a condenser
with 21 hollow central spindle e above, working up through a stuffing-box A" by a
hand screw and screw wheel A, for admitting either live steam or exhaust steam,
or a current of high pressure water from the chamber and branch g, g', (according
as these were admitted through taps and pipes to these) down through the point e
of the hollow spindle, to assist the force of the jet of water through the water
nozzle, admitted to the top water chamber by the branch A².
exhaust steam is admitted by the branches E, E", to the vacuum chamber E, so
as to meet the jet of water and be condensed in a set of three combining concentric
nozzles b, b, c, the last forcing the condensed air and water through the throat d' and
trumpet & into the discharge chamber E' of the apparatus, against the pressure of the
atmosphere, all as indicated by the arrows, producing the vacuum back in the pipes
and cylinders connected to the branches 2, the intermediate combining
nozzles, in this case being shown as fitted concentrically over the lower discharge
nozzle e, by rings and webs in a bored upper part at Ex of the outer case E. E',
secured either by radial feathers on the lower part of the nozzle #, or otherwise by
screws at from the outside of the case E, all so that these nozzles & b', may be raised
or lowered by the insertion or removal of rings at b to lengthen or shorten the jets
of water between the combining nozzles b, b, c, with little alteration or fitting, when
that is desired. For using this arrangement as a water-lifter, it would be inverted,
and the top g, g², and A", AI, and spindle, would be dispensed with, and have the
branch pipe from the water to be lifted directly attached to the top of the chamber A',
or to the lateral branch A², leading direct to the first central nozzle a, and in this case -
the water and combining nozzles a, b, b', would be lengthened, as indicated in dotte I
lines at in Figure 6, to admit only an annular jet of steam proportionate to the
pressure, high pressures requiring longer nozzles and a small entrance, compared
with that required for exhaust steam for producing a vacuum, the steam in th's.
case generally being the inducing fluid to draw the water through the apparatus.
This arrangement acts otherwise as indicated by the arrows and substantially as
described in reference to the former Figures 1 to 5.

male fluid-tight to prevent the admission of air with the fluids to the apparatus, which
might destroy the vacuum and the induction of the water through the apparatus:
and the water generally has been shown as passing through the centre of the first
nozzles in a central jet, and the steam admitted to it in an annular jet in the
ombining nozzles b, b, c, but it will be understood that the steam might be admitted
lown the central jet, and the water in a thin annular jet round it in the combining
ozzles. Or the exhaust or pressure steam might be made to enter through each
irst nozzle and pass into the water admitted in an annular jet through the second
ozzle, and the steam he also admitted in an annular jet through a third, or more

discharge pressure trumpets d.

Referring to the Injector shown in Figures 9 to 12 on Sheet 5, E, E', is the outer
case or shell, preferably made in two parts E, E, jointed by flanges at E, having
all the nozzles a, b, b, c, turned and screwed into these parts E, E, in line concentric
to each other, and with a closing-in screw plug E and E7 at the upper and lower
ends of the case E, E, for so fitting in the nozzles and discharge tube d. In this
arrangement of Injector, the steam is admitted by the branch to a double valve
seat chamber F', formed on one side of the upper part E of the case of the Injector.
with the valves f. f", fitted over each other and worked in line by one screw
spindle passed up through a stuffing-box F at top, worked by a hand wheel
outside, the lower valve f being so connected at to the upper valve f² or its
spindle, as to open slightly after the upper valve f. The valve thus admits
the steam to the upper chamber f and upper induction central nozzle, while the
lower valve admits the steam slightly after the upper valve f², to the lower
chamber f, and lower annular induction nozzle c. In this arrangement the water is
admitted by the upper branch E to the chamber Ex of the first combining nozzle b
fitted over a second induction nozzle b', having an overflow chamber B3 and outlet
branch B, formed between the nozzle and the nozzle . A second overflow
chamber 133 and outlet branch B is also formed between the second annular steam
induction nozzle e, and the throat d' of the delivery trumpet tube d, d¹, through
which the water is injected to pass through the discharge branch to the boiler or
other vessel into which the water is to be fed, an ordinary check or other valve
being fitted on the brauch, or the pipe leading from it to the boiler to prevent the
flowing back of the water through the apparatus, the direction of the steam and
water through the several valves, passages, and nozzles of the Injector being indicated
by the arrows in Figure 9. The improvements and action of the Injectors consist in
so carrying and combining the nozzles in one straight line through the centre of the
apparatus that they may form a complete apparatus having two or more distinct
converging combining steam and water nozzles a, b, b and c, with a separate overflow
chamber and branch or passage 133, 134, behind each open to the atmosphere and in
front of their delivery nozzles b, d, and so that two or more distinct steam branches
or chambers f. f, for each induction and combining nozzle a, b, and b', e, may be
governed by inlet steam valves f, f", preferably actuated by the same spindle or
handle f, each lower valve f", opening slightly after the other valve f above it as
required, and acting all as indicated by the arrows. Each overflow branch B', may
when desired be fitted with check valves opening outwards, and closing by their
own weight or otherwise, when a partial vacuum is formed in the overflow
chambers B³.
It will be understood that either live or exhaust steam may be used in these
Injectors, and that the first nozzle a shown as a steam nozzle may be a central water
nozzle to give a central water jet, while the steam might be admitted to the passage E
to give an annular jet in the first combining nozzle b, as indicated in the second
combining nozzle c. And although only one set of central and annular combining
nozzles have been shown in the outer cases E, E', of the Figures on Sheets 4 and 5,
described as for Water Lifters and Injectors, it is to be understood that two or more
sets of these nozzles and streams might be fitted in the outer cases each set fitte.l
concentrically in line with, and parallel to the others, receiving their steam from the
same chambers or valves, and also the water which would be delivered from
the several induction or delivery trumpets & into the same discharge chamber.
The main object and advantages of the multiple sets of nozzles of our invention in
one chest, and apparatus, are that the maximum length of each jet of water is
obtainable by adding one, two, or more of the intermediate combining nozzles bor b, b',
as shown in Figures 1, 5, 6, and 9 to suit the available head pressure or speed in the
particular circumstances, and so be able to shut off oe or more of the sets of
nozzles a and their trumpets d, to suit the weight of steam to be condensed, and open
them up when the engine is required to work to its maximum power,
