A FILTER- ING MACHINE, WHICH ACTS UNDER WATER, AND IS APPLICABLE TO THE FILTERING OF ALL LIQUIDS
Year: 1853

page_text: LETTERS PATENT to George Ferdinand de Fonvielle, of Marseilles,
No. 13, Rue de la Darce, France, for the Invention of "A FILTER-
ING MACHINE, WHICH ACTS UNDER WATER, AND IS APPLICABLE TO
THE FILTERING OF ALL LIQUIDS."
Sealed the 17th June 1853, and dated the 27th April 1853.
PROVISIONAL SPECIFICATION left by the said George Ferdinand
de Fonvielle at the Office of the Commissioners of Patents, with
his Petition, on the 27th April 1853.
I, GEORGE FERDINAND DE FONVIELLE, of Marseilles, No. 13, Rue de
la Darce, France, do hereby declare the nature of the said Invention
for "A FILTERING, MACHINE WHICH ACTS UNDER WATER, AND IS APPLICABLE
TO THE FILTERING OF ALL LIQUIDS," to be as follows:-
This apparatus consists of a vessel of metal, constructed by preference
of a cylindrical form, and perforated at its upper part with small holes,
through which the fluid enters after it has passed through a coarse
fabric, with which they covered, to prevent the larger impurities from
entering the apparatus. After entering this perforated cylinder, the
fluid passes through a stratum of wool or other fibre, sponge, or other

page_text: substance of a similar nature; then through a stratum composed of
pounded charcoal, mixed with small stones or grit; afterwards through
another stratum of wool or similar substance, when it arrives at a bed of
pebbles, from which it passes through a tube into another cylinder or
vessel, smaller than the first, to the bottom of which the tube of com-
munication passes, which tube is perforated with small holes in all that
part which is contained within this vessel. Round this tube, wool or
other matter is packed, so as to fill the vessel, and so that the fluid
which comes through the tube has to pass through the wool before it
can issue from the vessel through its side, which is perforated. The
fluid, which is now completely filtered, may be collected in any suitable
vessel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Ferdinand de Fonvielle, in the Great Seal
Patent Office, on the 25th October 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE FERDINAND DE FONVIELLE, of Marseilles, No. 13, Rue de la
Darce, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, hearing date the Twenty-seventh day of April, 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 George Ferdinand de Fonvielle, Her
special licence that I, the said George Ferdinand de Fonvielle, my
executors, administrators, and assigns, or such others as I, the said
George Ferdinand de Fonvielle, 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 "A FILTERING MACHINE, WHICH ACTS
UNDER WATER, AND IS APPLICABLE TO THE FILTERING OF ALL LIQUIDS," upon
the condition (amongst others) that I, the said George Ferdinand de

page_text: Fonvielle, 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 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 George Ferdinand de Fonvielle,
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 (that is to say):
This apparatus consists of a vessel of metal, constructed by preference
of a cylindrical form, and perforated at its upper part with small holes,
through which the fluid enters, after it has passed through a coarse
fabric, with which they are covered, to prevent the larger impurities
from entering the.apparatus. After entering the perforated cylinder, the
fluid passes through a stratum of wool or other fibre, sponge, or other
substance of a similar nature; then through a stratum composed of
pounded charcoal, mixed with small stones or grit; afterwards through
another stratum of wool or similar, substance, when it arrives at a bed
of pebbles, from which it passes through a tube into another cylinder
or vessel, smaller than the first, to the bottom of which the tube of
communication passes, which tube is perforated with small holes in all
that part which is contained within this vessel. Round this tube, wool
or other matter is packed so as to fill the vessel, and so that the fluid
which comes through the tube has to pass through the wool before it
can issue from the vessel through its side, which is perforated. The
fluid, which is now completely filtered, may be collected in any suitable
vessel.
And in order that my said Invention may be most fully under-
stood, and readily carried into effect, I will proceed to describe the
drawing hereunto annexed, which shows an elevation, Fig. 1, and a
vertical section, Fig. 2, of the filter. A, is a cylinder of metal, which is
placed inside the cistern or vessel in which the fluid is contained. The
upper part of this cylinder is perforated with small holes, which holes
are covered with a coarse porous fabric B, which is attached by the
hooks C, to the side of the cylinder A. The fluid having passed through

page_text: the fabric B, and being thus freed from its coarser impurities, enters
through the perforations of the cylinder A, where it is caused to pass pro-
gressively through a series of layers of filtering materials, the first of
which is composed of wool or similar substance, D; the second of a
mixture of charcoal and small stones or grit, E; the third of wool or
similar substance, F, like the first; and the last of gravel, G. After pass-
ing through all these layers, the fluid passes by the tube H, which passes
through the bottom of the cistern or vessel which contains the fluid, into
and to the bottom of another vessel K, the space between this vessel
and the tube being packed full of wool. The fluid passes through per-
forations in the tube H, through the wool, and escapes through per-
forations in the cylinder K, in a perfectly clear state, and may be
received in any suitable vessel.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I do not confine
myself to the precise details described; but what I claim is, the manner
of combining and arranging filtering materials above described.
In witness whereof, I, the said George Ferdinand de Fonvielle,
have hereunto set my hand and seal, this Eighteenth day of
October, in the year of our Lord One thousand eight hundred
and fifty-three..
