PROVISIONAL SPECIFICATION.
An Improved Feed Water Heater for the Utilization of Exhaust
Steam.
I, JOHN GEORGE Williams, Builders' Merchant and Contractor, Richmond
House, Poplar Avenue, Hagley Road, 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 to afterwards introduce
the heated water into a boiler or other place where it can be used to advantage.
In carrying out the first modification of my invention I provide a receiving
chamber the transverse section of which would be arched on the top surface and
parallelogramic on the bottom surface each end of the receiving chamber terminates
with a flange of suitable configuration to receive the end plate or cover, the end
flanges may project over the receiver passage any required distance or they may
project from the external face of receiving chamber only, so as to leave a clear
passage entrance to the internal surface of the receiving chamber.
I next provide two end plates or covers, one of the end plates would be pierced
with an outlet passage of suitable dimensions and from the outer surface of such
end plates would (by preference) project a short arm carrying a flange the surface
of such flange being by preference parallel with the outer surface of end plate the
end plates would be secured to the ends of receiving chamber by means of bolts and
nuts or by other equivalent mechanical means.
From the arched outer surface project a series of branches each branch terminating.
with a connecting flange.
I next provide a supply chamber which would by preference be of a circular
transverse section, from the supply chamber would project a series of branches, each
branch terminating with a connecting flange; the number of branches projecting
from the supply chamber would correspond with the number of branches projecting
from the receiving chamber.
I next connect to each branch flange of supply chamber a suitable cut-off tap or
cock, I next connect to each projecting flange or outlet face of each cut-off cock a
short branch pipe.
I next connect to each short branch pipe a diminishing T piece each lower branch
of each of such pieces is by preference diminished; I next connect to each lower
branch of each of such T pieces aforesaid a length of piping the bore of which will
be by preference less in diameter than the bore of the upper branch of T piece;
to the ends of each of this lower series of branch pipes would be attached faced
flanges, such series of faced flanges would then be connected to the branch flanges"
of receiving chamber; my new system of heater would be completed by inserting
connecting branches horizontally between each of the T pieces.
A vertical side elevation of the complete heater would present to view the
receiving chamber at the bottom and above the receiving chamber the cold water
supply chamber formed by connecting the T pieces together; above the cold water
supply chamber would be the row of cut-off taps and above such row of cut-off taps
would be the supply chamber the whole forming a frame formed of short pipes,
branches, T's, and cut-off taps.
The action of my improved water-heater is as follows:-
Exhaust steam would be conducted into the supply chamber from the cylinders
of engines, steam-hammers, or elsewhere by means of suitable conducting pipes, the
pressure of such exhaust steam would be exerted through the branches of supply

page_text: chamber, thence through the open cocks, thence through the pipes or branches
projecting therefrom into the † pieces; the exhaust steam so conducted would
strike against or impinge upon the stream of cold water flowing through the T pipe
cold water supply chamber, the steam would mingle with the cold water and assist
in driving such cold water through the diminished branches projecting from the
T pipes into the receiving chamber the water entering the receiving chamber heated
by the admixture of the condensed exhaust steam.
The continual pressure of the exhaust steam from the supply chamber would be
exerted on the water lying in or flowing through the receiving chamber.
The multitude of separate discharges into the receiver would tend to produce a
continuous pressure equivalent to or equal to the action of an injector.
The heated water in the receiving chamber would be conducted by suitable
conduits or supply pipes to the boiler or other place where it is desired to discharge
such heated water.
1
By a second modification I provide the receiving chamber, the exhaust steam
supply chamber, and the cut-off cocks, as described in first modification and connect
to each projecting flange or outlet face of each cut-off cock a short branch pipe or
a pipe made from several short branches reaching to and connecting with the
branch flanges of receiving chamber thus forming the framing of pipes without a
cold water conduit.
I next provide the cold water conduit from which projects short branches the
internal area of such short branches being less than the internal area of the main
conduit the difference in the area of the conduit passage and the area of the
passages of the branches varying in accordance with the number of such supply
branches, the cold water conduit would then be connected to the framing of pipes
either at the front or at the back, the branches connecting to faces, or spigots, or
faucets provided on the short pipes below the cut-off taps to receive them.
The action of the second modification would be similar to the action of the
first modification as the cold water would flow into the pipes below the cut-off
taps ready to receive the pressure of exhaust steam fully described in first
modification.

COMPLETE SPECIFICATION.
An Improved Feed Water Heater for the Utilization of Exhaust
Steam.
I JOHN GEORGE WILLIAMS, Builders' Merchant and Contractor, Richmond
House, Poplar Avenue, Hagley Road, 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 to afterwards
introduce the heated water into a boiler or other place where it can be used to
advantage.
In constructing my invention I use two modifications as hereinafter described.
The nature, scope, and general features of my invention will be more fully
understood from the following description taken in connection with the
accompanying drawings forming part thereof and in which
Figure 1 represents a front elevation of the first modification of heater.

page_text: Figure 1.
Figure 3 represents an elevation of indicator.
Figure 4 represents the end-plate short arm and connecting flange, combined in
one piece.
Figure 5 represents a front elevation of second modification.
Figure 6 represents an end view of Figure 5.
Figure 7 represents a section of Figure 5 on the line A. B.
Figure 8 represents in front elevation a branch-pipe suitable for use as a
substitute for the downtake pipe s, the fitting bb the downtake pipe and the
connecting flange w² of second modification.
Figure 9 represents a transverse section of Figure 8.
Figure 10 represents a plan of Figure 8.
In carrying out the first modification of my invention, I provide a receiving
chamber a the transverse section of which would be arched on the top surface 6 and
parallelogramic on the bottom surface d, each end of the receiving chamber
terminates with a flange e of suitable configuration to receive the end plate or
cover, the end flanges e may project over the receiver passage any required
distance, or they may project from the external face of receiving chamber only, so as
to leave a clear passage entrance to the internal surface of the receiving chamber.
I next provide the end plate or cover f pierced with an outlet passage of suitable
dimensions and from the outer surface of such end plate projects a short arm g
carrying a flange h, the end plate would be secured to the flange e of receiving
chamber by means of bolts and nuts; to the flange h I connect the flange; of
chambered branch k, such chambered branch k carrying a heat indicator /, the
flange m being provided for connecting to any required outlet conduit.
From the arched outer surface project a series of branches each branch n
terminating with a connecting flange a.
I next provide a supply chamber o which would by preference be of circular
transverse section, from the supply chamber would project a series of branches p
each branch terminating with a connecting flange g; the number of branches
projecting from the supply chamber would correspond with the number of branches
projecting from the receiving chamber.
Inext connect to each branch Hange of supply chamber, a suitable cut-off tap or
cock r, or in lieu of the series of cocks r I connect at each end of supply chamber o
or on any part of such supply chamber a suitable cut-off tap or cock; I next
connect to each projecting Hange or outlet face of each cut-off cock » a short
branch s.
I next connect to each short branch pipe a diminishing cross-piece t, eich lower
branch u of each of such cross pieces is by preference diminished; I next connect
to each lower branch of each of such cross pieces aforesaid a length of piping v,
the bore of which will by preference be less in diameter than the bore of the upper
branch of cross piece; to the ends of each of this lower series of branch pipes
would be attached faced flanges w (or in lieu of the separate parts I provide a
branch pipe as shewn at Figure 8) such series of faced flanges would then be
connected to branch flanges of receiving chamber; my new system of heater
would be completed by inserting connecting branches horizontally between each of
the cross pieces.
The vertical side elevation of the complete heater as shewn at Figure 1
presents to view the receiving chamber a at the bottom, and above the receiving
chamber the cold water supply chamber y formed by connecting the cross pieces
together.
Above the cold water supply chamber is the row of cut-off taps r and above
such row of cut-off taps is the steam supply chamber, the whole forming a frame
composed of short pipes, branches, cross-pieces and cut-off taps.
The action of my improved water-heater is as follows
Exhaust steam would be conducted into the supply chamber o from the cylinders

page_text: of engines, steam-hammers, or elsewhere by means of suitable conducting pipes,
of
the pressure of such exhaust steam would be exerted through the branches
supply chamber, thence through the open cocks », thence through the pipes or
branches s projecting therefrom, into the cross pieces; the exhaust steam so
conducted would strike against or impinge upon the stream of cold water flowing
through the cross-pipe cold-water supply chamber y, the steam would mingle
with the cold water and assist in driving such cold water through the diminished
branches n projecting from the cross-pipes into the receiving chamber a, the water
then entering the receiving chamber heated by the admixture of the condensed
exhaust steam.
'
The continual pressure of the exhaust steam from the supply chamber o would be
exerted on the water lying in or flowing through the receiving chamber a.
The heated water in the receiver a would be conducted by suitable pipes or
conduits connected to either end of the receiver, a blank flange f' would by
preference be secured over the flange e at one end of receiver a in lieu of the
flange ; the combined cover branch g and connecting-flange would be secured
to the other end of receiver; in some cases I can connect such combined parts
(shewn in detail at Figure 4) at both ends of receiver and dispense with the blank
flanges f¹.
ין
By a second modification of my invention I provide the receiving chamber ",
the exhaust steam supply chamber o and the cut-off cocks r as shewn and described
in relation to Figures 1, 2, 3, and 4 of first modification, such parts a, o and
being reproduced at Figures 5 and 6 of the drawings describing second modifica -
tion, I connect to each projecting flange or outlet face of each cut-off cock » a
short branch-pipe as shewn at s Figure 2 and also provide the downtake pipes
Figure 6 in connection with the receiver a of second modification as hereinbefore
described in relation to the receiver a shewn at Figures 1 and 2 of first modification,
but the cold water supply conduit of second modification is a distinct and separate
conduit placed in front or in rear of the framing of pipes as shewn at Figure 5,
such separate cold water conduit is marked, the internal passage extending from
the cold water supply cock connection past each downward pipe, the cold-water
supply pipe may be formed out of one continuous piece of piping on which would
be provided the required number of branches ready to connect to the T shaped
diminishing sockets cc or the sockets c c' of branch pipe shewn at Figure 9, the
connections may be made by screwed nipples ce² as shewn in the transverse section
Figure 7, such screwed nipple connection being suitable for moderate sized heaters,
but when the conduit z is four inches in diameter or over and the branches
one and half inches in diameter or over I prefer to make flanged connections.
In lieu of a separate cut-off cock for each downtake pipe, I in some cases prefer
to cut off the supply of steam at the point or points where it enters the steam-
supply-chamber o.
The cut-off cocks are shewn with upper flanges taking connection with the
flanges of supply chamber branches p, the branches n of receiving chamber are
also shewn with flanges taking connection with the face flanges of the downtake
pipes nevertheless I can where desired substitute spigot and faucet or nipple
connections in lieu of the faced flanges in both modifications of my invention, as
such connections can be varied to suit the dimensions of the pipes used, without
departing from the combination and arrangement of the several pipes and
parts, the combination of which produces the improved heater and constitutes my
invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is

page_text: 2nd. The making of a feed-water-heater by the combination and arrangement of
the parts illustrated and described in relation to the second modification.
3rd. In a feed-water-heater the utilization of an arched receiving-chamber, as
illustrated and described in relation to Figures 1 and 5.
