IMPROVEMENTS IN FEEDING STEAM BOILERS
Year: 1855

page_text: LETTERS PATENT to Peter Armand le Comte de Fontaine Moreau, of
4, South Street, Finsbury, London, and 39, Rue de l'Echiquier, Paris,
in the Empire of France, for the Invention of "IMPROVEMENTS IN FEEDING
STEAM BOILERS."-A communication.
Sealed the 19th October 1855, and dated the 9th August 1855.
PROVISIONAL SPECIFICATION left by the said Peter Armand le Comte
de Fontaine Moreau at the Office of the Commissioners of Patents, with
his Petition, on the 9th August 1855.
I, PETER ARMAND le Comte DE FONTAINE MOREAU, of 4, South Street,
Finsbury, London, & 39, Rue de l'Echiquier, Paris, in the Empire of France,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
FEEDING STEAM BOILERS" to be as follows, that is to say :-
The Invention communicated to me consists in condensing instantaneously
the whole or part of the steam at the moment that it escapes from the cylinder
and enters the waste pipe. This is effected by a direct injection of cold water,
which produces a partial vacuum under the piston, and thus assists its motive

a temperature of about 212° Fahrenheit, which is supplied to the boiler by
means of a pump suitably arranged for that purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Peter Armand le Comte de Fontaine Moreau in the Great
Seal Patent Office on the 9th February 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
ARMAND le Comte DE FONTAINE MOREAU, of 4, South Street, Finsbury,
London, and 39, Rue de l'Echiquier, Paris, in the Empire of France, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of August, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Peter Armand le Comte de Fontaine Moreau, Her special license that I, the
said Peter Armand le Comte de Fontaine Moreau, my executors, adminis-
trators, and assigns, or such others as I, the said Peter Armand le Comte
de Fontaine Moreau, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN FEEDING STEAM BOILERS," communicated to me from a foreigner
residing abroad, upon the condition (amongst others) that I, the said Peter
Armand le Comte de Fontaine Moreau, by an instrument in writing under
my hand and seal, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same is 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 Peter Armand le Comte de Fontaine
Moreau, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawing hereto annexed, and to the figures and letters marked thereon,
that is to say:-

page_text: This Invention consists in improved apparatus for condensing the waste
steam from high-pressure steam engines, and employing such condensed steam
(which is nearly at the heat of boiling water) for feeding steam boilers.
a
The Drawing represents an elevation of the apparatus. D is a pipe con-
veying the waste steam from the cylinder of a high-pressure engine into the
condenser I, the latter consisting of a copper vessel of a cylindrical shape.
The. steam entering this vessel is immediately condensed by means of cold
water, conveyed by the tube J and the branch tube K into the spreader C,
which vessel is of an hemispherical shape, and is provided with a cover per-
forated with small holes, which causes the cold water to enter the condenser in
finely divided state like that of rain, thus presenting a large cooling, surface
to the steam, which, becoming condensed, passes by the pipe E into the
receiver B, from which it is pumped to feed the boiler. Any condensed steam
in the condenser ascends through the pipe I. The receiver B is furnished
with a float F, which serves to indicate the level of the water. To the float is
secured a rod G, passing through a suitable stuffing box fixed to the cover of
the receiver. On the top of the rod is a small pin L, which enters the slot M
in the lever N. This lever is fixed to a stop-cock O on the pipe J. Thus,
the float, as it alternately rises and falls, regulates the injection of the cold
water into the condenser. The water which enters the pipe J is supplied by
a pump or from a reservoir, to which it is attached. P is another stop-cock
for carrying off the water left in the pipe J.
By the above arrangement of apparatus the following advantages are
obtained: First, by the sudden condensation of the steam in the condenser a
partial vacuum is formed in the condenser, thus increasing the effective power
of the engine. Secondly, the boiler being fed with condensed steam nearly at
a boiling point, produces a great economy in fuel, causes the incrustation of
boilers to be lessened, on account of the water being deprived of salts, and
earthy matters, and raises the evaporating power of the boiler. Thirdly, it can
be adapted to all kinds of stationary high-pressure steam engines and also to
locomotives.
Having now described the nature of the said Invention, and in what
manner the same is to be performed, I would have it understood that what I
claim is,--
First, the arrangement and construction of apparatus for condensing waste
steam from high-pressure steam engines in order to feed steam boilers with
water at nearly a boiling point, as herein-before described, and referred to in
the Drawing.

page_text: Secondly, the mechanical means for regulating the injection of cold water
into the condenser, as herein-before described, and referred to in the accom-
panying Drawing.
In witness whereof, I, the said Peter Armand le Comte de Fontaine
Moreau, have hereunto set my hand and seal, this Eighth day of 5
February, One thousand eight hundred and fifty-six.
