do hereby declare the nature of said Invention to be as follows:-
My Invention has for its object to provide apparatus by which the condensing
of exhaust steam can be very perfectly effected and it relates more especially
to the class of apparatus known as the Berryman water heater or analogous
apparatus According to my Invention I provide underneath the ordinary tube
plate and tubes a vessel through which cold condensing water is passed-Between
the top of this vessel and the ordinary tube plate is the double chamber into one
part of which the steam to be coudensed is admitted to pass through the ordinary
tubes into the second compartment and therefrom to the air pump-In front of the
inlet to and outlet from the cold water vessel aforesaid deflecting plates or surfaces
are arranged and tubes or passages pass through the said vessel the said tubes or
passages opening at one end into the one compartment into which the exhaust
steam enters and at the other end into the other or second compartment into which
the uncondensed steam passes on its road to the air pump-Water of condensation
passes down into these tubes or passages and is cooled therein and then passes up
into the said second compartment (draining off by the air pump) and presenting
a very efficient cooling surface for any uncondensed steam passing out from the
ordinary tubes-In order to create a positive up current of circulating condensing
water in the ordinary or upper part of the apparatus surrounding the ordinary
tubes I may make passages or holes for air and water from the water chainber
beneath through casings or channels past the steam inlet and outlet space thence
communicating by passages holes or pipes with outlets into the aforesaid upper or
ordinary part of the apparatus the said outlets being directed so as to discharge
the air and water in an upward direction.
The water of condensation will be comparatively cold when it leaves the
apparatus but if required as feed water it can be heated up again and grease
may be separated by the use of an ordinary Berryman or other heater working in
conjunction with the apparatus described.

J, JOSEPH WRIGHT of Tipton in the County of Stafford do hereby declare the
nature of said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
My Invention has for its object to provide apparatus by which the condensing
of Exhaust Steam can be very perfectly effected and it relates more especially to
the class of apparatus known as the Berryman water heater or analogous apparatus.
According to my Invention I provide in combination with such a heater or
analogous apparatus an arrangement whereby the water heater is rendered capable
of acting as a very efficient condenser of exhaust steam for vacuum as hereinafter
fully described with reference to the accompanying Drawings, Figure 1 of which
represents a front elevation, Figure 2 a side elevation, Figure 3 a plan, Figure 4 a
sectional elevation (on the line 1-2 Figure 3,) Figure 5 a sectional elevation (on
the line 3-4 Figure 3,) Figure 6 a sectional plan (on the line 7-8, Figure 4,)
Figure 7 a sectional elevation (on the line 5-6, Figure 3,) and Figure 8 a sectional
plan (corresponding to Figure 7,) of an apparatus constructed according to my
Invention.
The following is a description of the best means with which I am acquainted for
carrying my invention into effect but I wish it to be understood that the details
of construction and arrangement may be varied without departing from the nature
of my Invention.
A is the chamber and B are the tubes of an ordinary Berryman heater and
C. D. are the chambers beneath, the exhaust steam being passed into the chamber C
by the inlet c and after passing through the tubes B and into the chamber D
escaping by the outlet d and thence to the air pump.
Beneath the ordinary tube plate E and tubes B I provide a vessel F which is
covered with a tube_plate F³ forming the bottom of the chambers C and D and
through this vessel F condensing water is passed.-Between the top of the tube
plate F and the ordinary tube plate E are the aforesaid chambers C. D. g is the
inlet and h is the outlet for the condensing water which is passed through the
vessel F.
In front of the inlet g or the outlet h (or in front of both of them) a deflecting
plate or surface is arranged as shewn with regard to both at g² h' and the tubes or
passages as at i are immersed in the condensing water contained in the said
vessel F the said tubes or passages i opening at one end into the compartment C
into which the exhaust steam enters and at the other end into the other or second
compartment D into which any uncondensed steam may pass on its road to the air
pump. Water of condensation of the steam in the chamber C and tubes B passes
down into these tubes or passages i which are of such a capacity and length as to
retain the water for such a time as will enable the cold condensing water in the
vessel F to effectually cool it in its passage through the tubes and before it passes

page_text: up into the said second compartment D to be there employed as cold condensing or
injection water before being drawn off by the air pump the said water when it
arrives in the chamber D presenting a very efficient cooling surface of cold
injection condensing water for any uncondensed steam which may pass out from
the ordinary tubes B into the chamber D-The pressure in the vessel F should be
greater than that in the chamber A. This is provided for by supplying the
condensing water to the said vessel F by a suitable head or pressure the outlet
for the water from the said vessel F to the ordinary chamber A being through a
pipe provided with a regulating valve -There is an escape valve on the pipe j
at for safety as it relieves any excess of pressure in either the chamber A or
vessel F-There is a partition f in the centre of the vessel F (but with a way for
the water past it) dividing the vessel into two spaces to properly distribute the
condensing water and to support the tube plate F above it. The discharge ends
of the water tubes i into the chamber D should be elevated to a short distance
above the level of the plate F2 through which the said tubes i pass and in which
they are secured at both ends and these discharge ends should have perforations or
slots extending some distance down their sides so as to cause a slow or properly
regulated discharge of the re-injected water of condensation and thus cause the
said water to enter and pass equally through all the tubes i K is the escape pipe
for the water from the part A. In order to create a positive up current of
circulating condensing water around the upper tubes B in the ordinary or upper
part A of the apparatus I prefer to make passages or holes for air and water from
the vessel F through casings or channels m past the chambers C and D and thence
communicating by passages or holes n and pipes p with outlets projecting at
different distances into the upper chamber A of the apparatus the said outlets
being directed so as to discharge air and water from the vessel F into the upper
chamber A in an upward direction The water of condensation will be comparatively
cold when it leaves the apparatus at d and if required as feed water it can be
heated up again and the grease may be separated from it by the use of an
additional ordinary Berryman or other heater working in conjunction with the
apparatus described.
I have described and illustrated the Invention as applied to a Berryman heater
and with water as the cooling medium circulating round the tubes and from this
it will be understood that the Invention can be similarly applied to analogous
heaters or condensers and with the employment of any other suitable cooling
medium.
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:
First: The combination with a Berryman water heater or analogous apparatus
of a vessel through which cold condensing medium is passed and having tubes or
passages for receiving water of condensation from the said water heater or the like
so that the said water of condensation is cooled and utilized to further condense
the exhaust steam passed into the heater or the like substantially as described.
Second: In an apparatus of the kind claimed by the preceding claiming clause
the means for creating a positive upward current in the upper chamber A by
discharging water through pipes or passages from the vessel F. substantially as
herein before described with reference to the passages l m n and p.
Third The combination with the chamber A, tubes B and chambers C. D. of
a vessel F communicating with the chamber A and tubes i communicating with
the chambers C and D all being arranged substantially as and for the purpose
bereinbefore described.
Fourth-The combination with the chamber A tubes B and chambers C, D, of
a vessel F communicating with the chamber A. and tubes i fixed in a tube plate F²
and communicating with the chambers C and D the discharge ends of the tubes i

page_text: being arranged to project above the plate in which they are fixed so as to regulate
the passage of water thereinto there through and therefrom and present a surface
of cooled condensing water in the chamber D substantially as hereinbefore
described.
Fifth The arrangement and combination of parts constituting the apparatus
for condensing exhaust steam substantially as hereinbefore described and illustrated
in the accompanying drawings.
