We DRUITT HALPIN of 9 Victoria Chambers Westminster, in the County of
Middlesex Engineer and JAMES GRESHAM of the firm of Gresham and Craven of
Salford in the County of Lancaster Engineers and Machinists do hereby declare the
nature of said invention for "IMPROVEMENTS IN ARRANGEMENTS AND APPARATUS
FOR REMOVING THE WATER OF CONDENSED STEAM FROM THE JACKETS" OF
STEAM ENGINES AND OTHER VESSELS, PIPES OR CHAMBERS SUPPLIED WITH
STEAM,"
"-to be as follows:-
"
Our invention relates to and consists in arrangements and apparatus acting as
hereinafter described-The water of condensed steam flows to the lowest part of
the chamber or vessel in which it condenses and it is or may be conveyed by a pipe
from such vessel into a chamber having a "glass water guage" or other arrange-
ment to show the quantity therein and from thence, it is taken to the overflow
orifice of an injector which is or may be the one used to feed water to the boiler
which is supplying the steam that is being condensed, or to any other boiler
working at the same or a different pressure.
"
A cock or valve is or may be arranged on the pipe or passage leading to the
overflow orifice of the injector so that the communication may be opened or closed
as desired, and the outlet from the overflow orifice is or may be provided with a
selfacting valve that will open to allow the escape of overflow when starting the
injector and at other times, or the before mentioned cock may have as many
ways" as are required to shut and open the communication between the water
from the condensed steam and the Injector, and to shut and open the outlet froin
the overflow of the injector, to the atmosphere by this mode of action the water
from the condensed steam will be withdrawn from the vessel and carried along
with and by the current passing through the Injector into the boiler the ordinary
current of the injector producing by its friction what is termed an
" induced
current" in the pipes conveying the water of the condensed steam. When the
boiler is fed with water by a pump or pumps or from a main under sufficient

page_text: pressure, or in cases where the injector cannot be conveniently made use of as
herein before described, then our invention consists in causing the water from the
pump or pumps or main under sufficient pressure, or injector, to pass at the
required velocity through cones or nozzles similar to those of an injector having an
opening corresponding to the overflow orifice of an injector round which a cavity is
formed into which the water from the condensed steam is brought which is thus
drawn in by the current induced by the rapid passage of the water through the
apparatus and goes along with it to feed the boiler.
There is a selfacting valve to close against the return of the water from the
boiler.
When the water is pumped an air vessel is or may be used between the pump or
pumps and the nozzles of the apparatus to reduce the pulsation and make the flow
of the current more readily uniform..

Middlesex, Engineer, and JAMES GRESHAM, of the firm of Gresham and Craven of

the nature of said invention for IMPROVEMENTS IN ARRANGEMENTS AND APPARATUS
FOR REMOVING THE WATER OF CONDENSED STEAM FROM THE JACKETS OF STEAM
ENGINES AND OTHER VESSELS, PIPES OR CHAMBERS SUPPLIED WITH STEAM; and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
Our invention relates to and consists in arrangements and apparatus acting as
hereinafter described-The water of condensed steam flows to the lowest part of the
chamber or vessel in which it condenses and it is or may be conveyed by a pipe
or other arrange-
from such vessel into a chamber having a "glass water guage
ment to show the quantity therein and from thence, it is taken to the overflow
orifice of an injector which is or may be the one used to feed water to the boiler
which is supplying the steam that is being condensed or to any other boiler
working at the same or a different pressure.

A cock or valve is or may be arranged on the pipe or passage leading to the
overflow orifice of the injector so that the communication may be opened or closed
as desired, and the outlet from the overflow orifice is or may be provided with a
selfacting valve that will open to allow the escape of overflow when starting the
injector and at other times, or the before mentioned cock may have as many
" ways as are required to shut and open the communication between the water
from the condensed steam and the Injector, and to shut and open the outlet from
the overflow of the injector to the atmosphere-By this mode of action the water
from the condensed steam will be withdrawn from the vessel and carried along with
and by the currant passing through the Injector into the boiler the ordinary current
of the injector producing by its friction what is termed an induced current in the
pipes conveying the water of the condensed steam; When the boiler is fed with
water by a pump or pumps or from a main under sufficient pressure or in cases
where the injector cannot be conveniently made use of as, herein before described
then our invention consists in causing the water from the pump or pumps or main
under sufficient pressure or from an injector to pass at the required velocity
through cones or nozzles similar to those of an injector having an opening corre-
sponding to the water supply orifice of an injector round which a cavity is formed
into which the water from the condensed steam is brought which is thus drawn in
by the current induced by the rapid passage of the water through the apparatus
and goes along with it to feed the boiler. There is a selfacting valve to close
against the return of the water from the boiler.
When the water is pumped an air vessel is or may be used between the pump or
pumps and the nozzles of the apparatus to reduce the pulsation and make the How
of the current more nearly uniform.
Fig 1 is a sectional elevation of an arrangement of apparatus according to our
invention suitable for feeding the water of condensed steam of about atmospheric
pressure.
Fig 2 is a sectional elevation of an alternative arrangement which may be used
in place of part of the modification shown by fig 1.
Fig 3 is a longitudinal section of apparatus for carrying out the object of our
invention when the water of condensed steam is to be taken along with a jet or

page_text: current of water having sufficient velocity produced. by a pump injector, or by
water from a main or other vessel under sufficient pressure.
a is an ordinary injector in which steam is admitted at a¹, the water at a², and
the combined water and steam is discharged at a³.
a', represents the ordinary overflow orifice, and a³ the ordinary annular cavity
around the exterior of the cones.
The overflow outlet branch a has a junction for a valve casing b.
The casing b has a seating for a large valve c the outer end of which has the
centre part of a diaphragm c' secured to it by a screw and washer, the outer margin
of the diaphragm c³ being secured to a flange on the casing b, by a cap b', and
bolts, the cap b¹ having a hole to admit the atmosphere to the outer side of the
diaphragm.
Into the casing b another casing 62 is screwed fluid tight, in which the seating is
formed for a valve d opening outwards, and the stem of this valve (d) is guided in
a cap b³ screwing into the casing b². This casing b has a junction 6 for a pipe 65
leading to the chamber or source of supply of the water of condensed steam.
The apparatus acts as follows.
When the Injector is started or when their is an escape or overflow from the
injector its pressure in the passage a will cause the large valve c'to close-and
prevent the fluid passing to the pipe 6, and the small valve d will open and allow
the fluid to escape at 66, but when the Injector has started and is properly working
a partial vacuum is formed in the passage a', the small valve & will then be closed
by the pressure of the atmosphere acting on its exterior which will also act upon
the diaphragm c¹ and open and keep open the large valve c as long as there is a
partial vacuum in the passage a The water of condensed steam in such case then
passes from the chamber in which it condenses through the pipe 60 and through the
large valve c to the overflow orifice a' and is taken in by the passing jet.
Fig 2 is a modification which may be substituted for the parts having similar
letters of reference in fig 1-The parts in fig 2 are the same as those in fig 1-
except that the diaphragm c¹ is dispensed with and the outer end of the large
valve c is formed as a piston and made to fit the casing b.
In fig 3; e is the inlet pipe for the fluid from the pump or pumps or injector or
main or other source of pressure-It passes through a cone e¹ which discharges into
a contracting and expanding cone e² and then passes to the boiler.
There is an annular chamber e³ round the cone e' communicating with a branch 61
to which the pipe 65 is connected that brings the water of condensed steam from
the chamber or vessel from which it is to be removed.
In the passage et or pipe b there may be a valve that will open to allow fluid to
pass from the pipe 6s to the exterior of the cone e¹ but which will close against the
passage of fluid in the opposite direction.
When the apparatus shown by fig 3 is supplied by a pump or pumps, the jet
passing from the pumps through the apparatus, may be made uniform to a great
extent by an air vessel arranged similar to those used in fire Engines and other
pumps placed between the pump or pumps and the apparatus.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed:-We declare that
what we claim is,―
1. The withdrawing of the water of condensed steam from the chamber in which
it is formed or from a chamber connected therewith, and passing the same to a
steam boiler by conveying such water of condensed steam to the overflow orifice of
an injector to be drawn in and pass along with the current passing through the
Injector substantially as hereinbefore described.
2. The combination and arrangement of an injector and valve apparatus for
passing the water of condensed steam to a boiler substantially as hereinbefore
described and illustrated by figs 1 and 2 of the drawings.

page_text: 3. The withdrawing of the water of condensed steam from the chamber or
chambers in which it condenses and conveying it to an orifice in suitable apparatus
surrounding a jet of fluid passing at sufficient velocity from a pump or pumps,
injector or other source of pressure where the said water of condensed steam will he
drawn in and carried along with the current of fluid into the boiler substantially as
hereinbefore described.
4. The combination and arrangement of apparatus for withdrawing the water of
condensed steam and passing it into a boiler substantially as hereinbefore described
and illustrated by fig 3 of the drawings.
