I, JOSEPH WRIGHT of 16 Great George Street in the City of Westminster, Engineer
do hereby declare the nature of this 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 relates more especially to the kind of water heater known as the
"Berryman heater" and has for its object to make the said heaters so that a
very efficient separation of grease or floating impurities from the water of condensation
is effected and so that the condensed steam purifier or grease separator forms a part
of the heater itself (instead of being a separate vessel as hitherto) and consequently
economy in first cost and in the space occupied by the apparatus is effected. I
moreover do away with the necessity for a girder support or syphon bottom under
the bottom rib of the tube plate and also with the bottom strengthening lid or cover
hitherto used and I can collect all the grease and impurities and mud from the whole
apparatus into one vessel from which they can be drawn off or allowed to run off.
According to my Invention I provide under the heater proper a receptacle for the
water of condensation of the steam used in the apparatus which receptacle is, near
the upper part thereof in communication by means of overflow openings with a
second chamber or vessel constituting the condensed steam water purifier (into
which chamber the additional supply of water if needed is drawn) by which openings
grease or floating impurities pass off from the surface of the condensed steam water
in the receptacle under the heater, the said grease or other impurities thence passing
off by a syphon pipe into a third vessel into which also opens the mud cock for
clearing the heater proper. The lower part or body casting of the heater into which
the steam enters and from which any uncondensed steam escapes, I make of
considerable depth to accommodate inlet and outlet pipes of any desired diameter and
I make the lower part of the heater proper (that is the top of the said body casting)
of a deep angular form and I provide the lower part of the said casting with a flange

page_text: or depending web preferably inwardly inclined which constitutes a division between
the part wherein the water of the condensed steam is deposited and the part at
which the grease or floating impurity escapes through the openings aforesaid.
I provide the aforesaid second chamber or condensed steam water purifier with
diaphragm plates or divisions one to prevent any uncondensed steam or greasy
impurities in the steam water from passing into the part containing the ball-valve
which admits fresh water under the said diaphragm or division to the aforesaid second
chamber for the purpose of mixing with the condensed stean water to liberate the
grease from it by reducing its temperature quickly and another diaphragm at the
opposite end of the said second chamber to prevent any grease or like impurity from
being drawn off or pumped out of this chamber with the purified condensed steam
water.
The
I provide also an overflow syphon pipe in this said second chamber for the purpose
of drawing off the grease and other impurities at the surface of the water.
receiving end of this syphon pipe should be longer than the delivery end and be
provided with a funnel mouth at the top so that as the water rises in the said second
chamber the grease or other floating impurities may pass from the water surface
freely into the aforesaid third chamber into which the mud from the mud cock and
hand hole g can also run so that all the impurities from the whole apparatus can be
drawn into this third chamber which said chamber has its outlet or drain pipe for
the grense or like impurities projecting into it to such a distance as to maintain a
sufficient quantity of liquid in it to prevent splashing when the mud cock is opened
the said mud cock controlling a passage from the heater proper to the said third
named chamber.
The accompanying drawings illustrate a water heater and its adjuncts constructed
according to my Invention Figure 1 being a vertical section Figure 2 a front
elevation Figure 3 a horizontal section on the line 1, 2 Figure 1 and Figure 4 a plan.
A is the heater proper into which the water to be heated is passed it entering at a
and passing off at a². B are the tubes through which steam is passed 6 being the
inlet and the outlet for the heating fluid as in the Berryman heater. The lower
part of the heater A (that is the top of the body casting A³) I prefer to make angular
as shewn at 68 and underneath this is the chamber in which the water of
condensation from the steam is received. The bottom end of the said body casting B
is provided with a termination or dipping web b preferably conical as shown.
At the side of the chamber C is the chamber D provided with the supply cock and
float at d for the admission of additional water supply when required. This chamber D
communicates with the chambers D2 and D but between D and D2 at ‹ there is a
diaphragm or partition which should extend from the top down to within a short
distance of the bottom of the chambers. In the chamber D³ is fixed a diaphragm d
extending from near the top down to within a short distance from the bottoin so as to
leave a space at the top and another space at the bottom of the chamber through
which lattor space the water is drawn off by any suitable drawing off or pumping
device which passes the water up by the pipe into the heater A the said device
being in communication with the spaco at d. Projecting to above the normal water
level is the long leg (with a funnel mouth) of the outlet syphon pipe E the shorter
leg e terminating in the chamber 1. Through this syphon pipe grease and floating
impurities pass from the chamber D' into the chamber 1. % is a drain pipe
projecting into the chamber I to a distance to maintain a layer of water in the said
chamber so that when the mud cock J is opened to clear out the heater or the hand
hole is uncovered in washing out the apparatus, splashing is prevented. There
may be man-holes or hand-holes at any suitable positions. I have shewn thom
at g 9 g for giving access to the chambers C and D and to the interior of the
heater.
Communication between the chambers C and D³ is established by perforations in
the side of the top of the inner chamber Cat x and a water way from the chamber D
to the chamber D³ may be made either by a continuation of the chambers as at D¹
(Figure 3) or by a tube or tubes as at Dª (Figure 1) or by both.

page_text: 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.
1st. The arrangement and combination of parts constituting a water heater with
grease or floating imparity separator or condensed steam purifier combined in one
apparatus substantially as herein before described and illustrated in the accompanying
drawings.
2nd. In combination with a water heater the vessels Cand D³ with means for drawing
or passing off grease or floating impurities and for drawing or pumping off water
from below the surface substantially as herein before described.
3rd. In combination with a water heater the conical termination 6*, or dipping web,
dipping into the chamber provided with outlets for grease and floating impurities
at its upper part, substantially as hereinbefore described and illustrated in the
accompanying drawings.
4th. In combination with a water heater an inner and outer chamber beneath the
water heater proper which is provided with the dipping web and a passage or
passages for grease or floating impurities from one chamber to the other and therefrom
to an outlet and with a diaphragin or division extending above the water level and
with a passage or space beneath it and means for drawing off water which passes
through this space substantially as herein before described and illustrated in the
accompanying drawings.
5th. In connection with feed water heaters and condensed steam water purifiers
the chamber I with which the grease outlet e and the mud cock J communicate (and
into which also if desired the washing out water from the hand-hole g³ can enter)
the said chamber being arranged substantially as and for the purpose hereinbefore
described.
