page_text: LETTERS PATENT to Josiah Hampton, of Loughborough, in the
County of Leicester, Engineer, for the Invention of "IMPROVED
APPARATUS FOR CONDENSING STEAM AND PURIFYING AND HEATING WATER
FOR GENERATING STEAM OR OTHER PURPOSES.”
PROVISIONAL SPECIFICATION left by the said Josiah Hampton at the
Office of the Commissioners of Patents, with his Petition, on the
15th August 1878.
I, JOSIAH HAMPTON, of Loughborough, in the County of Leicester,
Engineer, do hereby declare the nature of the said Invention for "Im-
PROVED APPARATUS FOR. CONDENSING STEAM AND PURIFYING AND HEATING WATER
FOR GENERATING STEAM OR OTHER PURPOSES," to be as follows:-
My improved apparatus consists of two or more conical cases closed
at their upper and open at their lower ends, which lower ends are
bolted to the flange of a funnel connected to a atime escape pipe,
which is provided with a stop-cock. The innermost case has an open
space all round, except where there are tabs by which it is bolted

page_text: "
to the flange above named, the other cases have a flange all round,
and have a steam-tight joint where they are bolted to the funnel
flange; a pipe is attached to the outer case to convey the steam to
be condensed into the space between the outer and second cases; the
outer case is also provided with a pipe and stop-cock by which to
regulate the escape of the water formed by the condensed steam. An
injection pipe connected to a force pump is passed through the outer
and second cases to convey the water to be purified into the space
between the second and innermost cases, from which space it passes
under the bottom of the innermost case, and rises up into it until
full, from whence it passes to where it is required, the slime and other
impurities falling to the bottom into the funnel before named, from
which it may be ejected at pleasure. The top of the innermost case
is provided with a pipe which conveys the purified water to a boiler or
other recepticle.
The above constitutes one modification of my improved apparatus,
and a second modification consists in dispensing with the second case,
and instead of it I coil a pipe round the innermost case, and supply
such pipe with the steam to be condensed, the water formed by the
condensed steam escaping as before described. The water to be purifyed
is admitted from a force pump into the outer case, and passes along the
coil of pipe until it escapes under the lower edge of the innermost case
into it, depositing the slime and other impurities in the funnel, the
purifyed water being conveyed by a pipe into a boiler or other re-
cepticle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Josiah Hampton in the Great Seal Patent Office
on the 2nd February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
HAMPTON, of Loughborough, in the County of Leicester, Engineer, send
greeting.

Patent, bearing date the Fifteenth day of August, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Josiah Hampton, Her special licence that I, the

page_text: the said Josiah Hampton, my executors, administrators, and assigns, or
such other's as I, the said Josiah Hampton, my executors, administrators,
and assigns, should at any time agree with and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVED APPARATUS FOR CONDENSING
STEAM AND PURIFYING AND. HEATING WATER FOR GENERATING STEAM OR OTHER
PURPOSES," upon the condition (amongst others) that I, the said Josiah
Hampton, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals; should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW-KNOW YE, that I, the said Josiah Hampton, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings
forming a part of this Specification.
My improved apparatus consists of two or more conical cases closed
at their upper and open at their lower ends, which lower ends are
bolted to the flange of a funnel connected to a slime escape pipe,
which is provided with a stop-cock. The innermost case has an open
space all round except where there are tabs by which it is bolted
to the flange above named, the other cases have a flange, and
have a steam-tight joint where they are bolted to the funnel flange;
a pipe is attached to the outer case to convey the steam to be
condensed into the space between the outer and second cases; the
outer case is also provided with-a-pipe and stop-cock by which to
regulate-the-escape of the-water-formed--by the condensed steam. An
injection pipe connected to a force pump is passed through the outer
and second cases to convey the water to be purified into the space
between the second and innermost cases, from which space it passes
under the bottom of the innermost case, and rises up into it until
full, from whence it passes to where it is required, the slime and other
impurities falling to the bottom into the funnel before named, from
which it may be ejected at pleasure; the top of the innermost case
-O
-

page_text: is provided with a pipe which conveys the purified water to a boiler or
other receptacle.
The above constitutes one modification of my improved apparatus,
and a second modification consists in dispensing with the second case,
and instead of it I coil a pipe round the innermost case, and supply t
such pipe with the steam to be condensed, the water formed by the
condensed steam escaping as before described. The water to be purified
´is admitted from a force pump into the outer case, and passes along the
coil of pipe until it escapes under the lower edge of the innermost case
into it, depositing the slime and other impurities in the funnel, the 1
purified water being conveyed by a pipe into a boiler or other re-
ceptacle.
In carrying out my-Invention I employ several arrangements of
apparatus.
The first, seen in section at Figure 1, consists of three conical 1
cases A, B, C, bolted to the flange of a funnel E, which is provided
with a valve or stop-cock E¹, the central base B instead of being
bolted to the flange of the funnel may be bolted on to a flange
formed on the outside of the inner case C, the bottom of which case
has an open space all round except where there are tabs, by which:
it is bolted to the flange of the funnel, but in either arrangement
the cases A and B are made with a steam-tight joint at the bottom.
The case A. has perforated facing near the bottom to which is bolted
a short connecting pipe A¹, which may be bolted to the exhaust
steam pipe of the boiler to which the apparatus is applied, the exhaust
steam passes into the space between the cases A and B, and the un-
condensed portion out through the pipe A³, the water formed by the
condensed steam is drawn out through the pipe and stop-cock A³ into
the tank of the feed pump or other receptacle. The water to be
purified and heated passes from the force pump through the pipe F
into the space between the cases B and C, passing under the bottom
of the case O into the interior thereof, where the impurities fall into
the funnel E, and are let out when requisite through the valve E¹.
The water in its passage between the two inner cases derives a con-
siderable degree of heat from the steam between the two outer cases,
and in such heated state it escapes through the top of the case C
by means of the pipe G which passes through the whole of the cases,
from whence it may be conducted to a boiler or other receptac.e

page_text: A second arrangement is shewn in section at Figure 2. The apparatus
is placed in a chamber at the rear end of the flue of a boiler, which
may be provided with a smoke-consuming apparatus or not, in either
plan the hot air escaping from the flue before passing the chimney
shaft plays round the case B of the apparatus, and raises the water
to a high temperature; in this arrangement the water is admitted
between the cases A, B, by the pipe F from the force pump, it then
passes under the bottom of the case B, and out from the top of the
interior, through the pipe G into the boiler H, on its passage depositing
the impurities in the funnel E, from whence they are removed by the
pipe F. The pipe F is provided with a small cock to let the air
from between the cases. Figure 24 shews the relative positions of the
fire-bars and flue of a boiler with apparatus at the back thereof.
A third arrangement is shewn in section at Figure 8, and consists
of four cases A, B, C, D, the cases A, B, C, being each bolted to
the flange of the funnel E with a steam-tight joint, the case D may
have holes near the bottom, as shewn, or may be open all round
except where there are tabs by which to bolt it to funnel flange; this
arrangement allows the space filled with the exhaust steam to be
enclosed by spaces filled with the water required to be heated, the
exhaust steam passes through the pipe A¹ into the space between
the cases B and O, the condensed steam being let out through the
pipe A³, the water to be heated is admitted through the pipe F
filling the space between the cases A and B, and passes out through
the pipes F, F, into the space between the cases O and D, thence
out at the bottom of D, up to and through the pipe G into the
boiler H or other receptacle, the impurities being deposited in the
funnel, and as in the previous arrangements emptied through the .pipe.
Figure 8ª shows in plan the relative position of the pipes at the top of
the case A in the third arrangement.
A fourth arrangement is shown in section at Figure 4, where there
are two cases A and B, the case B being of considerable less height
than A to allow room for two perforated plates K and Ķ¹³ to be
placed above it, the inner case is open round the greater part of its
5 lower edge, and the outer case is bolted steam-tight to the flange
of the funnel E, the top of the case A in this instance is closed by
a plate through which pipes A³, A', and F are passed and secured
therein; the case A is provided with a gauge I to show the height

page_text: "
of the water within, the highest and lowest points thereof being shewn
by two series of horizontal lines. The exhaust steam is admitted
into the space between the cases A and B through the pipe A¹, which
. has perforations near its lower end which is open so that the steam
can escape into the interior when the water has risen to such height ||
as to close the open end; this pipe besides passing through the top
plate of the case also passed through the plates K and K³, each of
which are perforated with holes forming twice the area of the steam
inlet pipe A¹, the plate K is not perforated at those parts which are
immediately under the water inlet pipe F and steam exhaust escape
pipe A³, the unperforated space under the pipe F causing the water
as it enters to spread over the plate K and pass through it in drops
or thin streams, which meeting the exhaust steam condenses the
greater portion thereof, any remaining steam being forced to pass
up through the perforations before passing through the exhaust outlet
pipe A³, the injected water and condensed steam percolates through
the perforations in the lower plate K³, and passing under the bottom
of the case B deposits its impurities in the funnel L, from whence
they are removed through E¹, the purified and highly heated water
passing out through the pipe G into the boiler, or where required
the plate K above referred to is shown in plan partly perforated at
Figure 4^.
A fifth arrangement, shewn in section at Figure 5, and a plan of
the top plate at Figure 5ª, consists of two cases A and B between
which is coiled a pipe A³ through which the exhaust steam passes
from the pipe A³, any steam that may be condensed being drawn out
through the pipe A³, the heat given out from such exhaust steam
is absorbed by the water admitted through the pipe F, which passes
between the coils of the pipe A³ until it reaches the bottom of
the case B under which it passes, and depositing its impurities in
the funnel E passes out in a highly heated state through the pipe G
to the boiler, or where required, the impurities being let out through
the pipe F¹.
A sixth arrangement, shewn in section at Figure 6, consists of
three cases, the water from the force pump or other supply being
admitted into the outer case through a pipe in the cover of the case,
passes down the case, and under the bottoms of the central and inner
cases, on its passage depositing the impurities in the funnel, then out

page_text: through a pipe which passes through the covers of the three cases,
the exhaust steam being admitted into the space between the centre
and innermost cases by a pipe shewn at the left of the Figure, the
condensed steam being let out through a smaller pipe and stop-cock,
shown at the right of the Figure, and any uncondensed steam escaping
by a pipe passed through the covers of the central and outer cases;
by this arrangement the steam chamber is entirely surrounded by
water chambers, thereby condensing more steam and abstracting more
heat therefrom.
•
A seventh arrangement, shewn in vertical section at Figure 7, and
in plan at Figure 74, consists of one or more series of cases which
I place in a chamber or chambers constructed to receive them between
the boiler and the chimney flue. The water passes from the force
pump in the direction indicated by arrows, through the top of the
outer case of the first series, and under the bottom of the inner case,
leaving portion of the impurities in the funnel, then out by a pipe
passed through the tops of both cases into the next series of cases,
thence through each succeeding series, passing out through the last
to the boiler, or where required depositing portion of the impurities in
each of the funnels on its passage.
Having described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim, the employ- -|
ment of apparatus constructed substantially as herein-before described,
for condensing steam, and purifying and heating water for generating
steam or other purposes.
In witness whereof, I, the said Josiah Hampton, have hereunto
set my hand and seal, this Thirty-first day of January, in the
year of our Lord One thousand eight hundred and seventy-
Witness,
H. W. GOUGH, O. E.,
Nottingham.
