Year: 1861

page_text: LETTERS PATENT to Alphonse René Le Mire do Normandy, of Odin
Lodge, King's Road, Clapham Park, Surrey, Analytical Chemist, for the
Invention of "IMPROVEMENTS IN REFRIGERATING THE FRESH WATER
PRODUCED BY CONDENSING STEAM."
Sealed the 28th November 1861, and dated the 18th June 1861.
PROVISIONAL SPECIFICATION left by the said Alphonse René Le Miro
de Normandy at the Office of the Commissioners of Patents, with his
Petition, on the 18th June 1861.
I, ALPHONSE RENÉ LE MIRE DE NORMANDY, of Odin Lodge, King's Road,
Clapham Park, Surrey, Analytical Chemist, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN REFRIGERATING THE FRESH WATER
PRODUCED BY CONDENSING STEAM," to be as follows:-
My improvements consist in making the condenser in such a way that the
condensing tubes, instead of occupying the whole length of the cylinder or
vessel used for condensation (as in the apparatus known as Normandy's marine
aërated fresh water apparatus), occupy only a certain portion of the upper
part thereof, and that the lower part of the said cylinder or vessel used for
condensation is traversed by a tube into which the fresh water condensed in
the tubes of the condenser falls, and if the apparatus be that known as a
double or multiple distillation, mixes with the fresh water coming from the
evaporator, so that the fresh water from both sources (the evaporator and
the condenser, if the apparatus be a double or multiple distillation one, or
from the condenser only if the apparatus be a single distillation one) com-
municates by one of the extremities of a metallic coil placed in the lower part

page_text: of the condenser, in which coil the fresh water produced is refrigerated by the
condensing water which is running through the apparatus, and by which the
coil is surrounded, and issues at the other extremity of the coil in a cool state,
whence it is made to traverse a charcoal filter; or else the condensing tubes
may be made to occupy the whole length of the condenser, and the metallic
pipe into which the fresh water is to be refrigerated is coiled round the con-
lensing tubes of the condenser, so that the condensed water produced by the
apparatus is refrigerated, as has been just described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alphonse René Le Mire de Normandy in the Great Seal
Patent Office on the 13th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALPHONSE
RENÉ LE MIRE DE NORMANDY, of Odin Lodge, King's Road, Clapham Park,
in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteen day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-four year of
Her reign, did, for Ierself, Her heirs and successors, give and grant unto
me, the said Alphonse René Le Mire de Normandy, Her special licence
that I, the said Alphonse René Le Miro de Normandy, my executors,
administrators, and assigns, or such others as I, the said Alphonse René
Le Mire de Normandy, 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 REFRIGERATING THE FRESH WATER PRODUCED BY CONDENSING
STEAM, upon the condition (amongst others) that I, the said Alphonse René
Le Mire de Normandy, my executors or adininistrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Alphonse René Le Mire de Normandy,
do hereby declare the nature of my said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Drawings, and to the letters and figures marked thereon, that
is to say:
My improvements in refrigerating the fresh water produced by condensing
steam consist in arranging the apparatus in such a way that the condensing
tubes, instead of occupying the whole length of the cylinder or vessel used for
condensation (as in the apparatus known as Normandy's marine aërated fresh
water apparatus) occupy only a certain portion of the upper part thereof, and
the lower part is provided with a tube or tubes, or suitable refrigerating
apparatus, so constructed and placed that the water condensed in the upper
portion of the cylinder is refrigerated in the passing through the lower part of
the condenser.
The accompanying Drawings will clearly explain the arrangements by
which this is effected.
Figures 1 and 2 are vertical sections of apparatus adapted for effecting the
object in view; the same letters represent the same organs.
In Figure 1, A, A, A, A, A, are condensing tubes fixed as usual in the con-
denser A', A¹, of my apparatus, known as Normandy's marine aerated fresh
water apparatus; A', A¹, cylinder containing the sheaf of pipes A, A, A, A, A,
as in the ordinary condenser; B, B', low cap and central tube, into which
the steam condensed in the tubes A, A, A, A, A, falls, and is led through the
elbow pipo C into a T-piece D, where it mixes (if the apparatus be a double
or multiple distillation one) with the water coming from the steam trap E, in
communication with the evaporator of the Normandy's double distillation
apparatus, which evaporator not being necessary to the understanding of the
plan under consideration, and being otherwise well known, need not be repre-
sented here; C, elbow pipe, through which the fresh water from the condenser
is led into pipe D, which is the beginning of a coiled pipe or tube, and into
which the fresh water coming from the steam trap E, mixes with the con-
densed fresh water coming from the condensing tubes A, A, A, A, A;
D, T-piece, through which (if the apparatus be a double distillation one) tho
fresh water from the steam trap E passes along with the fresh water coming
from the elbow C; E, steam trap in communication with the evaporator of
apparatus known as my double distillation apparatus, which steam trap and
evaporator being well known, and having been described fully in Patent of
the Twenty-sixth May One thousand eight hundred and fifty-six, and not being
necessary to the intelligence of the plan under contemplation, need not be
otherwise mentioned here.
my

page_text: If the apparatus be a single distillation one the steam trap E and its pipe E
being dispensed with, the condensed fresh water at once passes from C to D,
and thence into the coil F, from which it issues at G into a cooled state, the
coil F being immersed, of course, in the water contained in the condenser A', A¹;
G', diaphragm reparating the condensing from the refrigerating tube or tubes;
this diaphragm is provided with an opening or free passage, so that the con-
densing water may be enabled readily to pass from the lower or refrigerating
part to the upper or condensing part of the cylinder.
In Figure 2, A, A, A, are condensing pipes, as before; H is the pipe leading
the fresh water of the condensing tubes A from the lower cap B into a lower
cap I, which lower cap I receives also (if the apparatus be a double distillation
one) the fresh water coming from the steam trap E, in communication with
the evaporator already already alluded to in Figure 1. J, J, J, J, J, J, J, J, are
pipes into which the fresh water ascends from the lower cap I into the cap K,
into which it is refrigerated by the condensing and refrigerating water, which fills
the condenser A', A¹, whence it issues through pipe L at M in a cooled state.
This pipe L may, if necessary, be coiled round and round the pipes J, so that
the fresh water may thus be further refrigerated before its final exit.
If the apparatus be a single distillation one, the steam trap E may of courso
be dispensed with, since in that case there is no evaporator, and the fresh water
passes simply from H to J, K, and L, and finally at M.
Having thus described my said improvements, I wish it to be understood
that I do not claim as of my Invention, or the exclusive use of pipes or
apparatus for condensing or refrigerating fresh water from steam, except when
employed in the manner and for the purpose above described; but what I
claim as the Invention intended to be secured by the said Letters Patent is,
the dividing the condenser into two parts, for the purpose of enabling the fresh
water previously condensed in the upper to be refrigerated in the lower part,
as herein-before described.
In witness whereof, I, the said Alphonse René le Mire de Normandy,
have hereunto set my hand and seal, this Thirteenth day of
December, in the year of our Lord One thousand eight hundred and
sixty-one.
