Year: 1872

page_text: LETTERS PATENT to Robert Sutcliffe, of Castle Mills, Idle, near
Leeds, in the County of York, Cotton Doubler, for the Invention
of "IMPROVEMENTS IN APPARATUS FOR UTILIZING EXHAUST STEAM FOR
HEATING FEED WATER FOR BOILERS AND OTHER PURPOSES."
Sealed the 10th October 1872, and dated the 10th August 1872.
PROVISIONAL SPECIFICATION left by the said Robert Sutcliffe at
the Office of the Commissioners of Patents, with his Petition, on
the 10th August 1872.
I, ROBERT SUTCLIFFE, of Castle Mills, Idle, near Leeds, in the County
5 of York, Cotton Doubler, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR UTILIZING EXHAUst Steam
FOR HEATING FEED WATER FOR BOILERS AND OTHER PURPOSES," to be as
follows, that is to say :—
My Invention relates to utilizing the steam in its passage from the
O cylinder to the condenser by abstracting the heat and transferring it

page_text: to the feed water for boilers, forming a compound condenser. For this
purpose I employ a box or chest fixed between the bottom part of the
cylinder and the condenser, into which is fixed a series of copper or other
metal pipes laid horizontally one above the other, and at sufficient
intervals to allow the exhaust steam to pass through; the steam in its
passage towards the condenser impinges at right angles on the copper
pipes filled with feed water which has been abstracted from the hot well.
The exhaust steam passes through the water heater in a blast at cach
stroke of the engine, and the water which it heats passes onwards to the
boiler or boilers (or may be used for other purposes) thus economizing
cold water for the condenser by abstracting heat from the steam. The
sides of the box or chest are made with inside flanges in which are
fitted two iron plates to receive the copper pipes, on these flanges are
also placed two lids firmly screwed or bolted down with nuts and bolts;
these lids are hollowed out, leaving a space between the iron plates
and the inside of the lids to receive the feed water in its passage from
the hot well to the boiler or boilers.
I can obtain the same result by passing the steam through the pipes
and the food water through the box or cliest.
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said Robert Sutcliffe in the Great Seal Patent Office
on the 9th January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
SUTCLIFEE, of Castle Mills, Idle, near Leeds, in the County of York,
Cotton Doubler, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of August, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Sutcliffe, Her special licence,
that I, the said Robert Sutcliffe, my executors, administrators, and
assigns, or such others as I, the said Robert Sutcliffe, 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

page_text: 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 APPARATUS FOR UTILIZING EXHAUST STEAM FOR HEATING FEED WATER FOR
BOILERS AND OTHER PURPOSES," upon the condition (amongst others) that
I, the said Robert Sutcliffe, 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 Robert Sutcliffe, 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 Drawing hereto
annexed, and to the figures and letters marked thereon, that is to say :-
My Invention relates to improvements in apparatus for utilizing
exhaust steam for heating feed water for boilers and other purposes, and
consists in utilizing the steam in its passage from the cylinder to the
condenser, by abstracting the heat and transferring it to the feed water
for boilers, thus forming a compound condenser. For this purpose I
employ a box or chest fixed between the bottom part of the cylinder
and the condenser, into which is fixed a series of copper or other metal
pipes laid horizontally one above the other, and at sufficient intervals
to allow the exhaust steam to pass through; the steam in its passage
towards the condenser impinges at right angles on the copper pipes,
the insides of which are filled with feed water which has been abstracted
from the hot well. The exhaust steam passes through the water heater
in a blast at cach stroke of the engine, and the water which it heats
passes onwards to the boiler or boilers, or may be used for other
purposes, thus economizing cold water for the condenser by abstracting
heat from the steam. The sides of the box or chest are made with
inside flanges in which are fitted two iron plates to receive the copper
pipes, on these flanges are also placed two lids firmly screwed or bolted
down with nuts and bolts; these lids are hollowed out, leaving a space
between the iron plates and the inside of the lids to receive the feed
water in its passage from the hot well to the boiler or boilers.

page_text: I can obtain a similar result by passing the steam through the pipes
and the feed water through the box or chest.
But in order to enable my improvements to be better understood, I
will proceed to describe the same by reference to the accompanying
Drawing, in which Figure 1 represents a front view with lid taken off
and shown partially in section; Figure 2 a sectional side view, and
Figure 3 a plan of the apparatus for utilizing steam. Similar lettors of
reference are used in the three views to represent similar parts.
A, box or chest fixed between the bottom part of the cylinder C and
condenser B, having inside flanges D cast on it to receive the two
wrought-iron plates E, in which a series of copper or other metal
pipes F are fixed horizontally, one above the other and at sufficient
intervals to allow the exhaust steam to pass through; upon the flanges D
are placed two lids G, firmly screwed or bolted down with bolts H, these
lids G are hollowed out, leaving a space I between the iron plates E
and the inside of the lids G. The lids G have also wrought-iron stays K
screwed in the metal of the lids and passing through the copper pipes F
taking the strain off the bolts H and resisting any extra pressure. The
exhaust steam passing through the opening M towards the condenser
through the opening N impinges at right angles on the copper or metal
pipes F, which are filled with feed water which has been abstracted
from the hot well through the pipe O. The exhaust steam passes
through the water heater in a blast at each stroke of the engine, and
the water which it heats passes onwards to the boiler or boilers (or it
may be used for other purposes) through the pipe P, thus economizing
cold water for the condenser by abstracting heat from the steam. In
proportion as the steam blast heats the water so does the water condense
the steam, thus forming a compound condenser.
A similar result can be obtained by passing the steam inside the
pipes and the feed water through the box or chest, or by reversing the
operation the apparatus may be used as a refrigerator.
Having thus described my Invention, and the best means I am
acquainted with for carrying the same into effect, I would have it under-
stood that I do not confine myself to the precise details shewn and described
as the same may be varied without departing from the peculiar character
of the Invention; but what I do claim is, the peculiar arrangement and
construction of apparatus for utilizing the exhaust steam to heat the

page_text: feed water for boilers and for other purposes, thereby economizing cold
water for the condenser as herein-before described and represented in
the accompanying Drawing.
In witness whereof, I, the said Robert Sutcliffe, have hereto set
my hand and scal, this Twenty-fourth day of December, in the
year of our Lord Qne thousand eight hundred and seventy-two.
