PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Water and Condensing
Steam.
I, JOHN IRELAND BOOKER, of Tong Road, New Wortley, Leeds, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to improvements in apparatus for heating water
and condensing steam and has for its object the construction of an efficient appar-
atus combining the several features and fulfilling the respective or suitably
combined duties of surface and jet heater and surface and jet condenser and is
particularly applicable for heating the feed-water of steam boilers by exhaust
steam and also for the condensation of exhaust steam.
Now in accordance with this my said invention I construct within a cylindrical
or other suitably shaped casing a convenient number say four of chambers or
divisions within the first or uppermost of which I form a series of annular com-
partments connected by means of tubes which pass through a second compara-
tively large or main chamber to a corresponding series of annular compartments
within a third or lower chamber in such wise that a continuous passage to and
fro between all the said annular compartments is formed. I form the said con-
tinuous passage by making the annular compartments in the uppermost chamber
of varying diameters in their relation to the annular compartments in the lower
chamber which latter may be opened to each other or separated the one from the
other by means of a water seal as may be desired. The main chamber through
which the tubes connecting the said annular compartments pass contains the
water to be heated say for the boiler-feed whilst a fourth or lowermost chamber
is or may be used for the deposit of dirt grease and other waste matter.
The exhaust steam inlet to the said annular compartments controlls a valve
operating a water-jet or jets which plays or play within the main chamber so
that as the supply of exhaust steam ceases the water-jet or jets is or are auto-
matically cut off." The passage or passages of the exhaust steam into the main
chamber and the escape of such steam into the atmosphere and also the outlet
or outlets of the boiler-feed or other water or the overflow are respectively con-
trolled by valves which may be arranged so as to work automatically or be set
by hand and so work independently.
It will be understood that the function of the apparatus is altered by arranging
the different valves to such positions as may be required by the nature of the
particular work desired.
The apparatus is or may be provided with cocks and guages and other
accessories.

Improvements in Apparatus for Heating Water and Condensing
Steam.
I, JOHN IRELAND BOOKER, of Tong Road, New Wortley, Leeds, in the County
of York, 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:―
This invention has reference to improvements in apparatus for heating water
and condensing steam and has for its object the construction of an efficient appar-
atus combining the several features and fulfilling the respective or suitably
combined duties of surface and jet heater and surface and jet condenser and is
particularly applicable for heating the feed-water of steam boilers by exhaust
steam and also for the condensation of exhaust steam.

or other suitably shaped casing a convenient number say four of chambers or
divisions within the first or uppermost of which I form a series of annular com-
partments connected by means of tubes which pass through a second compara-

tinuous passage by making the annular compartments in the uppermost chamber
of varying diameters in their relation to the annular compartments in the lower

which the tubes connecting the said annular compartments pass contains the
water to be heated say for the boiler-feed, whilst a fourth or lowermost chamber
is or may be used for the deposit of dirt grease or other waste matter.
The exhaust steam inlet to the said annular compartments controlls a valve
operating a water-jet or jets which plays or play within the main chamber so
that as the supply of exhaust steam ceases the water-jet or jets is or are auto-
matically cut off. The passage or passages of the exhaust steam into the main
chamber and the escape of such steam into the atmosphere and also the outlet
or outlets of the boiler-feed or other water or the overflow are respectively con-
trolled by valves preferably arranged to be set by hand as may be desired for the
particular work to be performed.
The accompanying illustrative sheet of drawing shews an apparatus for heating
water and condensing steam made substantially in accordance with this my
present invention.
The outer cylindrical casing 1 is divided by means of flanged plates 23 and 4
into chambers 5 6 and 7. The upper chamber 5 is divided by plates 8 into
compartments 9 10 11 and 12 whilst the lower chamber 7 is divided into com-
partments 13 14 and 15 by means of the plates 16 and water-seal 17. Tubes 18
passing through the main chamber 6 connect the respective compartments of the
chambers 5 and 7 in such wise as to form a continuous passage or way from the
outer compartment 9 to the centre compartment 12 as indicated by arrows in the
drawing. The outer casing 1 may be supported on a stand 19 resting in a grease
or waste pan 20 as shewn or if desired the waste pan may be made contiguous
with the outer casing. The inlet 21 to all the compartments of the chambers 5
and 7 is controlled by a valve 22 having a vertical spindle 23 the upper end of
which works within a guide or stuffing-box 24 whilst its lower end is connected

page_text: to a pin 25 secured to a lever 20 fulcrumed on a rocking shaft 27 which latter
penetrates the inlet pipe 21. The slotted lever 28 is keyed on the outer end of
the rocking shaft 27; the connecting rod 29 as shewn in full lines being suitably
secured at its upper end to the slotted lever 28 whilst its lower end is attached to
the lever 30 controlling the water-valve 31. The connecting rod 29 may when
desired be moved along the slotted lever 28 and thereby regulate the flow of water
through the water-valve 31. The valves 32 and 33 operated by hand-wheels 34
and 35 and spindles 36 and 37 respectively are arranged within the centre com-
partment 12 of the upper chamber 5. The valve 32 controlls the way to the
exhaust pipe 38 which leads to the atmosphere whilst the valve 33 governs the
passage through the pipes 39 and 40 to the main chamber 6. The water-jet 41
plays within the pipe 40 and is controlled by means of a valve 42 actuated by a
float 43 operating through a lever 44 fulcrumed at 45 to the pipe 40. The ver-
tical waste pipe 46 is connected with the main chamber 6 by the open way 47
and is arranged to exhaust through the valve 48 operated by the hand-wheel 49
and spindle 50 into the exhaust pipe 38.
An arrangement of valves X and Y and pipe Z leading to an air-pump such as
is generally used with condensers for service with marine engines may with
advantage be applied to my improved apparatus when used as a jet and or sur-
face condenser.
I will now proceed to describe by way of example certain functions of the
apparatus substantially as herein before set forth: premising that the function
of the apparatus may be altered by arranging the different valves to such posi-
tions as may be required by the nature of the particular work desired. In case
it be desired to employ the apparatus as a combined jet and surface heater the
valve 32 is operated by the hand-wheel 34 and spindle 36 and lifted so as to
close the exit to the exhaust pipe 38 by way of the centre compartment 12 the
valve 33 being opened so as to allow a passage through the compartment 12 to
the main chamber 6. The connecting rod 29 is secured to the slotted lever 28
so that the water valve 31 and jet 41 will be in turn operated by the movement
of the valve 22. The exhaust steam as it enters the apparatus through the in-
let 21 lifts the valve 22 which in turn starts the water-jet 41. The exhaust
steam then passes through the several compartments by way of the tubes 18 (as
shewn by arrows on the drawing) thereby heating by surface contact the water
in the main chamber 6. When the exhaust steam reaches the centre compart-
ment 12 in the chamber 5 it passes down the pipes 39 and 40 and comes in con-
tact with and heats the spray from the water-jet 41 and afterwards travels into
the chamber 6 and thence through the open way 47 valve 48 and the exhaust
pipe 38 into the atmosphere (see arrows on drawing). The volume of water in
the main chamber 6 is shewn by a gauge glass 51. As the volume of water
reaches a predetermined level 52 (preferably corresponding to the open way 47)
the water-jet 41 is cut off by the valve 42 operated by the float 43. The heated
water within the main chamber 6 may be drawn off through a delivery pipe 53
one end of which is placed within the tube 54 secured by a tie-piece 55 to the
casing 1. The tube 54 reaches above the water level 52 in order to prevent float-
ing waste matter finding its way through the delivery pipe 53. It will be seen
that any waste matter floating at the water level 52 will be carried into the
vertical waste pipe 46 from whence it may be drawn off through a cock 56 or
in any other suitable way. Any sediment within the chamber 6 may be drawn
off through the pipe 57 leading to the waste pan 20 whilst any sediment within
the chamber may be led into the waste pan 20 through the pipe 58 or cock 59.
The volume of water in the chamber 7 is indicated by a gauge glass 60.
The apparatus may be employed as a jet and surface condenser by closing the
valves 32 and 48 thereby shutting off the outlets to the exhaust pipe 38. It will
be seen that the exhaust steam after passing through the series of tubes con-
necting the several compartments in the chambers 5 and 7 will be to some extent
condensed by surface contact and the surplus steam will afterwards pass from the

page_text: centre compartment 12 in the chamber 5 to the pipes 39 and 40 and there meet
and be condensed by the water-jet 41. In this case the water of condensation
may be delivered through the valves X and Y to the air-pump pipe Z or in any
other convenient manner.
To make the apparatus serve as a surface heater the valve 33 is closed thereby
preventing the entry of steam into the main chamber 6-the steam heating the
water fed into the chamber 6 through the water-jet 41 as it passes through the
respective tubes and compartments the heated water being drawn off through
the delivery pipe 53.
The apparatus may be used as a surface condenser by closing the outlet valves 32
and 48 and also closing the valve 33 controlling the entrance to the main cham-
ber 6 the water of condensation being drawn away through the valves X and Y
and air-pump pipe Z or in any other convenient manner.
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:
1. In apparatus for heating water and condensing steam apparatus consisting
of any convenient number of chambers some of which are divided into compart-
ments suitably connected so as to form a continuous passage or way the entry
of exhaust or other steam being through a valve operating suitable mechanism
for controlling a water-jet or jets and the general combination and arrangement
of valves for altering the function of the apparatus as may be desired all sub-
stantially as hereinbefore described and shewn.
2. The improved apparatus for heating water and condensing steam constructed
arranged and operating substantially as hereinbefore described and shewn in
the accompanying illustrative drawings.
