PROVISIONAL SPECIFICATION.
An Improved Feed Water Heater for use with Exhaust Steam.
We JOHN GEORGE WILLIAMS Builders Merchant and Contractor Richmond
House Poplar Avanue, Hagley Road, and JOHN PRINCE Engine Fitter of
12 Eyre Street Spring Hill, both of Birmingham in the County of Warwick do
hereby declare the nature of this invention to be as follows :-
This invention has for its object the utilization of exhaust steam from the
cylinders of steam engines and elsewhere to heat water, and so introduce into the
boiler, heated water instead of cold and thereby reduce the consumption of coal or
other fuel.
In carrying out our invention we provide a receiving chamber and such receiving
chamber would by preference be of a circular transverse section although we may
in some cases make the receiving chamber of an oval transverse section or of a
polygonal transverse section, or of any other suitable transverse section in accordance
with the volume of exhaust steam to be introduced and in accordance with the
quantity of cold water passing into the receiving chamber.
The inlet end of the receiving chamber is formed to taper into a neck of smaller
transverse section than that of the receiving chamber such reduced end terminates
with a connecting flange which may be round, oval, or of other suitable shape.
The outlet end of receiving chamber is formed by preference of a transverse
sectional area equal to or nearly equal to the transverse sectional area of the
receiving chamber although we can in some cases form a reduced neck at the
outlet end in a similar manner to that described in reference to the inlet end.
In either case the outlet end would terminate with a connecting flange which
may be round, oval, or of other suitable horizontal plan.
From the receiving chamber project one, two, or more branches, each branch
terminating with a connecting flange.
Our improved exhaust steam heater as hereinbefore described constitutes the
main portion of our invention.
We will now proceed to describe the manner in which our receiving chamber is
connected to exhaust steam and also to feed water.
The exhaust steam from the cylinders of an engine may be conducted into any
ordinary or suitable steam trap or steam chamber we should by preference provide
a steam trap or chamber on the lower part of which would be provided a well or
receptacle to receive the condensed steam or water to this steam trap we connect
two or more steam pipes and carry such steam pipes to the receiving chamber
and connect them to the flanges of the two or more branches of such receiving
chamber.
We next connect the inlet end of receiving chamber to any suitable water service
supply pipe and we then connect the outlet end of receiving chamber to a boiler
supply pipe or pipes or conduit.
At any suitable and convenient part of the exhaust steam supply pipes we
connect suitable cut off taps or cocks our improved heater is then ready for use.
-We turn
In using our improved heater we proceed in the following manner:-
on the cocks and introduce exhaust steam into the receiving chamber we then turn
on cold water supply at inlet end and such cold water becomes heated by means of
the exhaust steam and passes through the outlet end of receiver into the boiler
supply pipes or conduit, at a high temperature, thus the boiler supply pipes if
properly covered and protected from the cold air will convey to the boiler, water
already heated to a temperature of 190 degrees more or less.

page_text: The first introduction of exhaust steam into the receiver will produce a partial
vacum; the inlet water will flow in and as it becomes heated it will be driven out
by the continual pressure of the exhaust steam.
The supply of condensed steam will be regulated in accordance with the amount
of cold water entering the receiving chamber, a small boiler could be supplied
with one pipe of condensed steam, a twenty feet boiler may require two supply
pipes of condensed steam, a thirty feet boiler may require three supply pipes of
condensed steam and we vary the size of the inlet cold water supply pipes and the
outlet hot water supply pipes in accordance with the volume of exhaust steam
introduced into receiving chamber.
The principle underlying our invention consists in the inlet water passage to
receiver being of smaller area than the receiver so that the water entering from
the inlet pipe or passage flows along the bottom of receiver the remaining space
or area of receiver being continually filled with exhaust steam such exhaust steam
giving up its heat to the shallow stream of cold water condensing therein and
adding to the volume of water in the receiver, the pressure of the coloum or
coloums of exhaust steam continually entering the receiver forming the driving or
forcing power that forces the heated water out of the receiver, into the outlet
conduit, the outlet conduit being situated at a lower level than the cold water inlet
and being also of larger area so that the combined inlet water and condensed steam
water will readily flow out of the receiver.
The combination of the parts described in the first part of this Specification
being the means of carrying out the principal such combination of parts for the
purpose described constituting our invention.

COMPLETE SPECIFICATION.
An Improved Feed Water Heater for use with Exhaust Steam.
We JOHN GEORGE WILLIAMS Builders Merchant and Contractor of Richmond
House, Poplar Avenue, Hagley Road and JOHN PRINCE Engine Fitter of
.12 Eyre Street, Spring Hill. both of Birmingham in the County of Warwick 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:
This invention has for its object the utilization of exhaust steam from the
cylinders of steam engines and elsewhere to heat water, and so introduce into the
boiler, heated water instead of cold, and thereby reduce the consumption of coal or
other fuel.
We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is constructed and used.
Figure 1. represents the receiving chamber and connections one portion being
shewn in section.
Figure 2. represents a plan of Figure 1. on the line A B.
Figure 3. represents a sectional end view of Figure 1. on the line C D.
Figure 4. represents an end view of Figure 1. viewed from the arrow.
In carrying out our invention we provide a receiving chamber a and such
receiving chamber would by preference be of a circular transverse section as shewn
at a Figures 1, 2, 3, and 4 although we may in some cases make it of an oval,
poligonal, or other suitable transverse section in accordance with the volume of
exhaust steam to be introduced and in accordance with the quantity of cold water
passing into such receiving chamber.

page_text: The inlet end of receiving chamber is formed into a neck 6 of smaller trans-
verse section than the main body such neck end terminating with a connecting
flange c which may be round, oval, or of other suitable shape.
The outlet end of receiving chamber is formed by preference of a transverse
sectional area equal to or nearly equal to the transverse sectional area of main
body of chamber although we can in some cases form a reduced neck at the outlet
end, in either case the outlet end would terminate with a connecting flange d
which may be round, oval, or of other suitable horizontal plan.
From the receiving chamber a project one, two, three or more branches e, each
branch terminating with a connecting flange f.
We will now describe the manner in which our receiving chamber is connected
to exhaust steam and also to feed water.
The exhaust steam from the cylinder of an engine may be conducted into any
ordinary or suitable trap or steam chamber: we should by preference provide a
steam trap or chamber on the lower part of which would be provided a well or
receptacle to receive the condensed steam or water, to this steam trap we connect
two or more steam-pipes m and carry such steam pipes to the receiving chamber
and connect them to the flanges of the two or more branches e of receiving
chamber.
We next connect the inlet end flange c to the flange of any suitable water
service pipe or connect the inlet end to the service pipe by any other suitable
mechanical means, we then connect the outlet end of receiving chamber to a boiler
supply pipe by means of the connecting flanges d and k or by any other suitable
mechanical means.
At any suitable and convenient part of the exhaust steam supply pipes m we
connect suitable cut off taps or cocks o our improved heater is then ready
for use.
In using our improved heater we proceed in the following manner :-We turn
on the cocks o and introduce exhaust steam into the receiving chamber a we then
turn on cold water supply at inlet end and such cold water becomes heated by
means of the exhaust steam and passes through the outlet end of receiver into
the boiler supply pipes or conduit j, at a high temperature, thus the boiler supply
pipes (if properly covered and protected from the cold air) will convey to the
boiler, water already heated to a temperature of 190 degrees more or less.
The first introduction of exhaust steam into the receiver will produce a partial
vacum; the inlet water will flow in and as it becomes heated it will be driven out
by the continual pressure of the exhaust steam in conjunction with the action of
the force pump of engine.
The supply of exhaust steam will be regulated in accordance with the amount
of cold water entering the receiving chamber a, a small boiler could be supplied
with one pipe m of exhaust steam, a twenty feet boiler may require two supply
pipes m of exhaust steam, a thirty feet boiler may require three supply pipes m of
exhaust steam and we vary the size of the inlet cold water supply pipes and the
outlet hot water supply pipes in accordance with the volume of exhaust steam
introduced into receiving chamber.
The principal underlying our invention consists in the inlet water passage to
receiver being of smaller area than the receiver so that the water entering from
the inlet pipe or passage flows along the bottom p of receiver a the remaining
space or area of receiver being continually filled with exhaust steam such exhaust
steam giving up its heat to the shallow stream of cold water condensing therein
and adding to the volume of water in the receiver, the pressure of the coloumn or
coloumns of exhaust steam continually entering the receiver in conjunction with
force pump of engine forming the driving or forcing power that forces the heated
water out of the receiver, into the outlet conduit, the outlet conduit ; being
situated at a lower level than the cold water inlet h and being also of larger area
so that the combined inlet water will readily flow out of the receiver.
The combination of the parts described in the first part of this Specification

page_text: being the means of carrying out the principal such combination of parts for the
purpose described constituting our invention.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is,
1st. The making of a feed-water heater in the manner described, for the purpose
of June 1892.
