CERTAIN IMPROVEMENTS IN STEAM BOILERS
Year: 1853

page_text: LETTERS PATENT to Peter Armand Le Comte de Fontaine Moreau,
of the English and Foreign Patent Office, 4. South Street, Finsbury,
London, and 39, Rue de l'Echiquier, Paris, for the Invention of
CODMAN TO THE CODAY BATTERS " A communication
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 14th May 1853.
I, PETER ARMAND LE COMTE DE FONTAINE MOREAU, of the English
and Foreign Patent Office, 4, South Street, Finsbury, London, and
39, Rue de l'Echiquier, Paris, do hereby declare that the nature of the
Invention for "CERTAIN IMPROVEMENTS IN STEAM BOILERS" to be as
follows:-
The Invention consists in employing a series of iron tubes for
generating steam, and afterwards transmitting the same to the boiler,
by which I obtain a larger. amount of heating surface and an economy
of combustible.
The heating apparatus is composed of an optional number of tubes

page_text: fixed at their extremities to two boxes, which allow communication
between them, one of the tubes traverses the box in front of the
apparatus, and communicates with the boiler so as to allow the passage
of the steam from the apparatus to the boiler.
This communication can be cut off by a cock 2, which is placed at
one of its extremities, the other end being fixed to the boiler. Another
cock 3, is placed on a tube having one end in the box in front of the
apparatus and the other in the boiler; this cock allows water to enter
from the boiler into the apparatus. 5, is a guage cock to indicate that
there is water in the apparatus. An atmospherical valve 4, is also
adapted.
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 14th November 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
PETER ARMAND LE COMTE DE FONTAINE MOREAU, of the English and
Foreign Patent Office, 4, South Street, Finsbury, London, and 39,
Rue de l'Echiquier, Paris, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of May, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth 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 licence that 1, the said Peter Armand Le Comte
de Fontaine Moreau, my executors, administrators, 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 tinic 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 Inven-
tion for "CERTAIN IMPROVEMENTS IN 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,

page_text: by an instrument in writing under my hand and seal, should particularly
lescribe 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 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 ascertained in and by the following statement thereof,
reference being had to the figures of the annexed Drawings, in which
the same letters of reference indicate parts which are similar, that is
to say:
The Invention communicated to me consists in applying to boilers
of steam engines an evaporating apparatus varying in form and dinien-
sions, and susceptible of being removed without stopping the working
of the engine.
Figure 1, of Drawing I. represents a longitudinal section of the
boiler and of a furnace one hundred and sixty horse power steam
engine, with the improved apparatus applied, shewing the orifice
through which the apparatus communicates with the boiler.
Figure 2, Drawing II., represents a front elevation of the same;
Figure 3, a plan; and Figures 4, and 5, sections of the apparatus.
The apparatus A, is composed of iron or other metal tubes a, a, a",
the number of which is variable. They are fixed at their extremities
to two boxes or chambers , by which they communicate with each
other. One of the tubes, a', only communicates with the boiler for the
passage of steam generated in the tubes of the apparatus. This com-
munication can be intercepted by means of the stopper B, which is
fixed at one of the extremities of the tube a', the other end of the
stopper being fixed to the boiler.
A stopper C, is also placed on one of the extremities of the pipe a",
on the fore part of the apparatus; the other end of the stopper being
fixed to the boiler. The cock C, regulates the supply of water to the
apparatus. A guage cock E, Figure 2, is fixed on the fore part of the
apparatus to indicate the height of water in it. An air valve D, is also
employed.

page_text: The tubular apparatus herein-before described is set on each of the
furnaces h, h, Figure 2, and is fixed to them by means of screw bolts;
they are independent of each other, and offer the advantage of allowing
one of the apparatuses to be taken down when necessary without stop-
ping the other. For this purpose I have only to push the fire under the
apparatus to be taken down to the bottom of the furnace, to shut the
cocks B, and C, and unscrew the two bolts G, and take off the braces
which maintain the two cocks on the fore part of the apparatus. The
apparatus can then be withdrawn from its place without stopping the
working of the engine. Care has to be taken to close by means of
an iron plate the vacant space left by the apparatus withdrawn.
The part which is placed at the bottom of the furnace not being
fixed allows dilatation to take place without causing any damage either
to the tubes or to the boxes of the apparatus.
And having now described the nature of the Invention communicated
to me, and the best manner I am acquainted with of putting the same
into exccution, I wish it to be understood that I do not claim any of
the several organs taken separately. But what I claim as new and
intended to be protected by the herein-before in part recited Letters
Patent, is,
The applying to furnaces of steam engines a tubular apparatus for
heating the water before it is supplied to the main boiler, as herein-
before described, reference being had to the figures of the Drawings.
In witness whereof. I, the said Peter Armand Le Comte de
Fontaine Moreau, have hereto set my hand and seal, this
Twelfth day of November, in the year of our Lord One thousand
eight hundred and fifty-three.
Witness,
A: H. PATTISON.
