page_text: LETTERS PATENT to Henry Kinsey, of Robin Hood Works, Notting
ham, Engineer, for the Invention of "IMPROVEMENTS
THE MANU-
FACTURE OF SURFACE CONDENSERS, HOT WATER APPARATUS, AND IN STEAM
BOILERS AND WATER HEATERS FOR THE SAME."
Sealed the 7th June 1870, and dated the 18th December 1869.
PROVISIONAL SPECIFICATION left by the said Henry Kinsey at the
Office of the Commissioners of Patents, with his Petition, on the
18th December 1869.
I HENRY KINSEY, of Robin Hood Works, Nottingham, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE, OF SURFACE CONDENSERS, HOT WATER APPARATUS, AND IN STEAM
BOILERS AND WATER HEATERS FOR THE SAME," to be as follows:-
In constructing that class of steam boilers where the boiler is made
up of several units or separate chambers, each formed with corrugated
sides, I form each of such chambers with a tube running along its lower
end..and this tube I form in one piece of metal with the two corrugated

page_text: sides of the chamber. The tube I form to project at each of its ends
beyond the corrugated sides, and the tubes may have flanges formed
upon them, to which covers may be affixed, or to enable two or more
such chambers to be connected to one another the upper end of each
chamber may similarly be formed with a tube running along and pro-
jecting beyond it, or the upper ends of the sides may terminate in flat
plates to enable covers or ends to be fixed into them. Chambers thus
formed with corrugated sides and with a tube along their lower end
formed in one piece with the sides may be formed by first corrugating
a sheet of metal with longitudinal corrugations, and subsequently
hammering or pressing out the corrugations across a portion of the
centre of the plate and all around its edges. The plate is then doubled
over at the central flattened portion to bring the corrugated parts of
the plate on each side of it opposite to and parallel with one another.
The central part of the plate where it is thus doubled over is made
broader than the other parts, and as the plate is bent such projecting
parts of the plate are bent likewise, and are subsequently shaped into
tubes and welded, brazed, or rivetted up. The ends of such tubes may
then have flanges welded, brazed, or rivetted on to them. The flattened
ends of the plate may have flanges formed on or affixed to them, and
the flat side edges may be rivetted, brazed, or welded up to close them;
or in place of first corrugating the whole length of the plate the corru-
gations may only be formed in such parts of the plate as are required
to be corrugated, or the corrugations may be formed in the sides after
the plate has been doubled over by pressing the two sides on to a mould
or form placed between them. The two corrugated sides of each
chamber may be subsequently tied together with stays, as described in
the Specification of a former Patent granted to me on the Third day of
December 1868 (No. 3684), or if the several chambers are to be enclosed
by a strong casing such stays may be omitted. The compartments or
cells of surface condensers may also be formed in a similar manner to
that above described. In place of forming the chambers or parts of
boilers from plates corrugated longitudinally, as above described, the
corrugations may be made transversely of the plates, and the plates
when doubled over may be rivetted, welded, or brazed together at the
edges, which are brought together.

page_text: -
The gratings or fire-bars of steam boiler furnaces I form of rods or
thick wire carried by a rectangular frame; the wires or rods are bent
around one side of the frame, and are led across and bent around the
opposite side, the wire or rod being bent for rather more than a
complete: circle around each of the two sides, so that the end of each
wire or rod so bent round shall come between the adjacent wires and
form distance pieces to keep the several wires or rods at the desired
distance apart from one another. If a strengthening rod is carried
across the centre of the grating, then the wires or rods as they are led
across this rod may each be coiled once around it.
In order to heat the water to be supplied to steam boilers such as
above described, and to other steam boilers, I cause the feed water
before it is forced into the boiler to pass over a number of shelves or
plates placed one below the other and enclosed in a casing, through
which a portion of the exhaust steam from the engine may be led, the
steam being compelled to circulate over the surface of the several plates.
The feed water is supplied at the top of the casing and trickles down
from shelf to shelf, dropping from the end of one shelf on to the shelf
below, and after running over the surface of this shelf dropping down
on to the next, and so on.
i
Feed water heaters such as above described have before been proposed,
but according to my Invention I form such apparatus with a moveable
cover, and I carry the several shelves on a vertical rod or rods, so that
all of the shelves may simultaneously be lifted out from the casing of
the heating apparatus to be cleaned. At the bottom of the casing is a
small well, from which the water is led through a filter to the force
pump, by which it is to be forced into the boiler. The ordinary exhaust
pipe is led up by the side of the heating apparatus, and a valve is
provided, by which any desired amount of the exhaust steam can be
passed through the apparatus. This valve may be acted on by the
force pump in such manner as to admit the exhaust steam or part of
it to the apparatus whenever the feed pump is set to work. When this
small well at the bottom of the feed water heating apparatus is full
of heated water a float contained in it may be caused to open a valve
at the end of an outlet passage to allow any excess of water to flow
away

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Kinsey in the Great Seal Patent Office on
the 18th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
KINSEY, of Robin Hood Works, Nottingham, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of December, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Kinsey, Her special licence that
I, the said Henry Kinsey, my executors, administrators, and assigns, or
such others as 1, the said Henry Kinsey, 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 "IMPROVEMENTS IN THE MANUFACTURE
OF SURFACE CONDENSERS, HOT WATER APPARATUS, AND IN STEAM BOILERS AND
WATER HEATERS FOR THE SAME," upon the condition (amongst others) that
I, the said Henry Kinsey, 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 Henry Kinsey, do hereby declare
the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:-
In constructing that class of steam boilers where the boiler is made
up of several units or separate chambers, each formed with corrugated
sides, I form each of such chambers with a tube running along its lower
end, and this tube I form in one piece of metal with the two corrugated
sides of the chamber. The tube I form to project at each of its ends
beyond the corrugated sides, and the tubes may have flanges formed
upon them, to which covers may be affixed, or to enable two or more

page_text: such chambers to be connected to one another. The upper end of each
chamber may similarly be formed with a tube running along and
projecting beyond it, or the upper ends of the sides may be fitted with
covers or ends in any suitable manner. Chambers thus formed with
corrugated sides and with a tube along their lower end formed in
one piece with the sides may be formed by first corrugating a sheet of
metal with longitudinal corrugations, and subsequently hammering or
pressing out the corrugations across a portion of the centre of the plate
and all around its edges. The plate is then doubled over at the central
flattened portion to bring the corrugated parts of the plate on each side
of it opposite to and parallel with one another. The central part of the
plate where it is thus doubled over is made broader than the other parts,
and as the plate is bent such projecting parts of the plate are bent like-
wise, and are subsequently shaped into tubes, and welded, brazed, or
rivetted up.
The ends of such tubes may then have flanges welded,
brazed, or rivetted on to them. The flattened ends of the plate may have
flanges formed on or affixed to them, and the flat side edges may be
rivetted, brazed, or welded up to close them; or in place of first
corrugating the whole length of the plate the corrugations may only be
formed in such parts of the plate as are required to be corrugated, or
the corrugations may be formed in the sides after the plate has been
doubled over by pressing the two sides on to a mould or form placed
between them. The two corrugated sides of each chamber may be
subsequently tied together with stays, as described in the Specification
of a former Patent granted to me on the 3rd day of December 1868
(No. 3684), or if the several chambers are to be enclosed by a strong
casing, such stays may be omitted. The compartments or cells of sur-
face condensers may also be formed in a similar manner to that above
described. In place of forming the chambers or parts of boilers from
plates corrugated longitudinally as above described, the corrugations
may be made transversely of the plates, and the plates when doubled
over may be rivetted, welded, or brazed together at the edges, which
are brought together. Hot water apparatus may similarly be formed of
chambers with corrugated sides, and with tubes at top and bottom.
A side view of one unit or chamber of a steam boiler constructed
as above described is shewn at Figure 1 of the Drawings hereunto
annexed; a vertical section of the unit or chamber is shewn at Figure 2,
and a plan view at Figure 3.

page_text: To insure the circulation of the water in each unit or chamber of the
boiler I prefer to place in each a water circulator, such as described in
the Specification of a former Patent granted to me on the Fifth day of
June 1869, No. 1747. One of these tubes is shewn at Figure 2, set in
its place in the unit or chamber.
What I claim as respects this part of my Invention is, the constructing
the units or chambers of steam boilers, surface condensers, and hot
water apparatus, substantially in the manner herein described.
The gratings or fire-bars of steam boiler furnaces I form of rods or
thick wire carried by a rectangular frame; the wires or rods are bent
around one side of the frame, and are led across and bent round the
opposite side, the wire or rod being bent for rather more than a
complete circle around each of the two sides, so that the end of each
wire or rod so bent round shall come between the adjacent wires and
form distance pieces, and keep the several wires or rods at the desired
distance apart from one another. If a strengthening rod is carried
across the centre of the grating, then the wires or rods as they are led
across this rod may each be coiled once around it. A grating so
constructed is shown at Figures 4 and 5 of the Drawings annexed.
What I claim as respects this part of my Invention is, the constructing
gratings to be used in place of the ordinary fire-bars of a furnace,
substantially in the manner herein described.
In order to heat the water to be supplied to steam boilers, such as
above described, and to other steam boilers, I cause the feed water
before it is forced into the boiler to pass over a number of shelves or
plates placed one below the other and enclosed in a casing, through
which a portion of the exhaust steam from the engine may be led, the
steam being compelled to circulate over the surface of the several plates.
The feed water is supplied at the top of the casing, and trickles down
from shelf to shelf, dropping from the end of one shelf on to the shelf
below, and after running over the surface of this shelf dropping down on
to the next, and so on.
Feed water heaters such as above described have before been pro-
posed, but according to my Invention I form such apparatus with
a moveable cover, and I carry the several shelves on a vertical rod or
rods so that all of the shelves may simultaneously be lifted out from
the casing of the heating apparatus to be cleaned. At the bottom of
the casing is a small well from which the water is led through a

page_text: filter to the force pump, by which it is forced into the boiler. The
ordinary exhaust pipe is led up by the side of the heating appa-
ratus, and a valve is provided by which any desired amount of the
exhaust steam can be passed through the apparatus. This valve may be
acted on by the force pump in such manner as to admit the exhaust
steam or part of it to the apparatus whenever the feed pump is set to
work. When the small well at the bottom of the feed water heating
apparatus is full of heated water a float contained in it may be caused to
open a valve at the end of an outlet passage to allow any excess of water
to flow away.
Figure 6 shews a vertical section of a feed water heater constructed
as above described. a is the outer casing of the apparatus, which is by
preference cylindrical; b, b, are the shelves carried on the vertical
rods o; d is a cover at the top of the casing, which can readily be taken
off to allow the rod.c and shelves carried by it to be lifted out. The
way in which I prefer to form the shelves is shown in plan view at
Figure 7. e is a water inlet at the top of the case a; f is the exhaust
pipe from the engine, and g a valve by which the steam can either be
caused to pass away through the pipe h, or any desired portion of it can
be directed through the case a of the feed water heater; k is a well at
the bottom of the case a. The water accumulating in this well is drawn
through the pipe into the filter m, and is drawn off from the bottom
of the filter through the pipe n.
I claim the constructing feed water heaters, substantially in the
manner herein described.
In witness whereof, I, the said Henry Kinsey, have hereunto set my
hand and seal, this Eighteenth day of June, in the year of our
Lord One thousand eight hundred and seventy.
Signed in presence of
THOMAS BALL,
Justice of the Peace for
the Town & County of the
Town of Nottingham.
