CERTAIN IMPROVEMENTS IN STEAM GENERA- TORS
Year: 1859

page_text: LETTERS PATENT to Marc Antoine François Mennons, of the British and
Foreign Patent Offices, 39, Rue de l'Echiquier, Paris, in the Empire of
France, for the. Invention of "CERTAIN IMPROVEMENTS IN STEAM GENERA-
TORS." A communication from Frédéric Simian, residing at Marseilles.
Sealed the 18th March 1859, and dated the 3rd January 1859.
COMPLETE SPECIFICATION filed by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his
Petition and Declaration, on the 3rd January 1859; pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent Offices,
39, Rue de l'Echiquier, Paris, in the Empire of France, send greeting.
WHEREAS I am in possession of an Invention for "CERTAIN IMPROVEMENTS
IN. STEAM GENERATORS," communicated to me from a foreigner residing abroad,
and have petitioned Her Majesty to grant unto me, my executors, adminis-
trators, and assigns, Her Royal Letters Patent for the same, and have made
solemn declaration that it is a communication.
NOW KNOW YE, that I, the said Marc Antoine François Menṇons, do
hereby declare that the following Complete Specification under my hand and
seal fully describes and ascertains the nature of the Invention, and the
manner in which the same is to be performed, reference being had to the
accompanying Drawing, and to the letters marked thereon, that is to say :-

page_text: The Invention communicated to me consists in the addition to boilers and
other steam recipients of an auxiliary feeding apparatus, for the introduction of
cleansing or protecting solutions, and in the arrangement for effecting this
introduction during the work of the boiler by the pressure of the steam
evolved. The accompanying Drawing represents. a section of the apparatus.
A is the upper reservoir; B, upper stop-cock; C, lower reservoir; D, lower
stop-cock; E, stop-cock of the steam tube J; F, escape cock; G, plunge
pipe H, level of the protecting or cleansing solution; I, top of the boiler;
J, steam tube.
When using this apparatus under pressure, the upper and lower stop-cocks
B and D are closed and the escape cock F opened, to let off the steam con-
tained in the recipient C; the upper stop-cock B being then opened, the
protecting composition is poured into the reservoir A until it reaches the level
of the dotted lines H; at this point the liquid flows from the escape cock F,
which should be immediately closed. The upper stop-cock B being also
closed, there remains between it and the level H a space acting as reservoir
to the steam passing from the boiler through the pipe J and its stop-cock E,
which is opened at the same moment as the lower stop-cock D. The pressure
of the steam at H on the surface of the protecting solution forces the latter
by the plunge pipe G to the bottom of the boiler, where it exercises its specific
action either on the water or on the metal, as the case may be.
Having thus described the nature of the said Invention and the manner of
carrying it into execution, I would have it understood that what I claim is,
the addition to steam boilers or generators of an auxiliary feeding apparatus,
substantially as above described, for the introduction of cleansing or protecting
solutions of all kinds, and the peculiar arrangement for effecting this intro-
duction by steam pressure without interrupting the work of the boiler.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereunto set my hand and seal, this First day of January, in the year
of our Lord One thousand eight hundred and fifty-nine.
