IMPROVEMENTS IN CONDENSING STEAM ENGINES."
Year: 1858

page_text: LETTERS PATENT to Richard Glanville, of Bermondsey, in the County of
Surrey, Engineer, for the Invention of "IMPROVEMENTS IN CONDENSING
STEAM ENGINES.""
Sealed the 10th September 1858, and dated the 18th March 1858.
PROVISIONAL SPECIFICATION left by the said Richard Glanville at
the Office of the Commissioners of Patents, with his Petition, on the
18th March 1858.
I, RICHARD GLANVILLE, of Bermondsey, in the County of Surrey, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CONDENSING STEAM ENGINES," to be as follows:-
The improvements relate to making use of the exhaust steam from con-
densing engines as it passes to the condenser as a means of giving increased
heat to the feed water in its passage to the boiler, and which also tends to
facilitate the operation of condensation.
For this purpose I cause the exhaust steam in its passage to the condenser
to pass through a series of tubes, chambers, or other passages amongst or
around which the feed water from the hot well or other supply passes to the
boiler.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
GLANVILLE, of Bermondsey, in the County of Surrey, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of March, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Richard Glanville, Her special licence that I, the
said Richard Glanville, my executors, administrators, and assigns, or such
others as I, the said Richard Glanville, 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 CONDENSING STEAM ENGINES," upon the condition (amongst
others) that I, the said Richard Glanville, 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 Richard Glanville, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
The improvements relate to making use of the exhaust steam from con-
densing engines as it passes to 'the condenser as a means of giving increased
heat to the feed water in 'its passage to the boiler, and which also tends to
facilitate the operation of condensation.
For this purpose I cause the exhaust steam in its passage to the condenser
to pass through a series of tubes, chambers, or other passages, amongst or
around which the feed water from the hot well or other supply passes to the
boiler; apparatus thus arranged I denominate a "supplemental condenser and
feed water heater."
But that the nature of these my improvements may be better understood,
I will proceed to describe the Drawings annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 represent vertical and transverse sections of apparatus
arranged according to my Invention; Figures 3 and 4 represent a plan and
side view of the same. a, a, is a pipe or way for conducting the steam after
it has been used in the cylinder to the condenser; b is the feed pump for
forcing, as is well understood, the water from the condenser to the boiler;
c and d are the feed passages to the boiler. But it will be seen that the feed
water in passing from the pipe c to the pipe d passes through a chamber e,
formed with a series of tubes or passages e¹, between or around which the
water freely passes from the pipe c to the pipe d, whilst the steam in passing
through the parts of the pipe a is caused to pass through the tubes e', whereby
such steam will be considerably reduced in temperature by contact with the
cooler surface of these tubes e¹ before it enters the condenser, and the feed
water will at the same time have its temperature increased.
Having thus described the nature of my said Invention, and an arrange-
ment of means by which the same may be carried into effect, I would have it
understood that I do not confine myself to the precise details or to the form
and arrangement of parts shewn and described, as these may be varied with-
out departing from my Invention; but what I do claim is, the so arranging
and combining parts of condensing steam engines, that the steam in its passage
to the condenser may pass through a scries of tubes, chambers, or passages
amongst or around which the feed water is forced in its passage to the
boiler.
In witness whereof, I, the said Richard Glanville, have hereunto set my
hand and seal, this Thirtieth day of August, in the year of our Lord
One thousand eight hundred and fifty-eight.
Witness,
