quier, Paris, Patent Agent, for the Invention of "A NEW OR
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 12th March 1853.
T, PETER ARMAND LE COMTE DE FONTAINE MOREAU, of 4, South
Street, Finsbury, London, do hereby declare that the nature of the
Invention communicated to me for "A NEW OR IMPROVED APPARATUS
FOR FILTERING LIQUIDS" to be as follows:-
The Invention consists of a tube or vessel of felt or other flexible
filtering material or fabric, having an internal support to prevent it
from collapsing, the said internal support consisting either of a helical
or corkscrew-formed coil of wire, or a perforated tube of tin plate or
sheet metal, or of a support of any other form and material which will
prevent the said tube from collapsing, and which will not impede the
filtration. When the filtering tube is made of a material possessing
sufficient rigidity to resist the pressure to which it will be subjected an

page_text: internal support is unnecessary. The said filtering tube is closed at
one end, and furnished at the other with a tap, cock, or tube, and the
said filtering tube is put into the barrel or other reservoir containing
the liquid to be filtered, the said tap or cock being external to the said
barrel or reservoir and at its lower part; or the filtered liquid may be
drawn off from the interior of the said tube at the upper part of the
same, or it may be drawn off at both ends of the same, and the said
tube may be placed in the harrel or other reservoir either in a vertical,
horizontal, or intermediate position. The said tube or filtering vessel
is also made either round, square, flat, oval, or any other shape that
may be most suited to the vessel. the contents of which are to ho

filed by the said Peter Armand Le Comte de Fontaine Moreau,
in the Great Seal Patent Office, on the 9th September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
ARMAND LE COMTE DE FONTAISEMOREAU, of No. 4, South Street, Fins-
bury, in the County of Middlesex, and 89, Rue de l'Echiquier, Paris,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of March, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Fler reign, did, for Herself. Ller heirs and successors, give and
grant unto me, the said Peter Armand Le Comte de Fontainemoreau,
Her special licence, that I, the said Peter Armand Le Comte de Fon-
tainemorean, my executors. administrators, and assigns, or such others
as I, the said Peter Armand Le Comte de Fontainemoreau, my exe-
cutors. 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 NEW OR
IMPROVED APPARATUS FOR FILTERING LIQUIDS," being a communication

page_text: from abroad, upon the condition (amongst others) that I, the said Peter
Armand Le Comte de Fontainemoreau, 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 Peter Armand Le Comte de Fon-
tainemorcan, 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 (that is to say):
The said Invention consists of a tube or vessel of felt or other
flexible filtering material or fabric, having an internal support to pre-
vent it from collapsing, the said internal support consisting either of a
helical or corkscrew-formed coil of wire, or a perforated tube of tin
plate or other metal, or of a support of any other form and material
which will prevent the said tube from collapsing, and which will not
impede filtration. When the filtering tube is made of a material pos-
sessing sufficient rigidity to resist the pressure to which it will be
subjected, an internal support is unnecessary. The said tube or fil-
tering vessel is closed at one end, and furnished at the other with a
tap or other outlet; the said filtering tube or vessel being placed in
the liquid to be filtered, and the said tap or outlet passing to the
exterior of the vessel containing the liquid to be filtered. The said
liquid passes from the exterior to the interior of the said filtering-tube
or vessel, and runs from the said tap or outlet.
The drawing represents several modifications of the said Invention.
Figure 1, represents, in vertical section, one method of carrying the said
Invention into effect; a, is the reservoir or vessel containing the water or
other liquid to be filtered; b, is a cage or frame of wire, supported on the
plate c; d, is the filtering tube or vessel of felt, or other fabric, supported
on the wire cage b, and fastened at its open end to the plate c, by tying
or otherwise, at e; f, is a tube in the middle of the plate c, which said
tube opens into the interior of the filtering tube d, and through which
tubef, the filtered liquid passes. The filtering apparatus b, c, d, e, f, may
be fixed, as represented, on a partition g, which divides the vessel a, so

page_text: that the water which passes through the filtering tube d, may collect in
the compartment a', to be drawn ofl' as required at the stop-cock h.
Figures 2, and 3, represent the Invention as I prefer to apply it to large
cisterns or vessels. Figure 2, represents an external view of the filtering
apparatus; and Figure 3, represents the same in section. k, is the tube of
felt, or other fabric, in passing through which the liquid is filtered; the
said tube is closed at one end and open at the other, and is drawn
over and supported by the helical coil of wire l; m, is a pipe passing
through the side of the reservoir or vessel 1, and fixed in its place by
the screwed nut o; the filtering tube, is fastened, by tying or otherwise,
to the collar m', on the end of the pipe m, in the interior of the vessel
or reservoir; a tap or stop cock p, is affixed to that end of the pipe m,
which is external to the vessel n; the filtering tube k, may be of any
length, and may be placed vertically or horizontally in the reservoir
with which it is used, or it may be coiled up in the said vessel. On
opening the stop cock p, the water or liquid passes through the filtering
tube k, to its interior, and out at the said stop cock. Figure 4, repre-
sents in vertical section, and Figure 5, in plan, the said Invention
applied as a filterer for coffee or other infusions; 9, is the vessel con-
stituting the upper part of the coffee pot, and into which the materials
of which the infusion is to be made are put; this vessel q, communicates
by a piper, with the lower part of the coffee pot, or the reservoir for
the filtered infusion; 8, is the wire frame supported on the plate t.
The felt or filtering material is tied to the plate t, and frame s, round
the collar t'; a pipe u, in the middle of the platet, screws into the pipe r,
which communicates with the lower part of the coffee pot, and when
the filter is screwed in the said pipe, no liquid can pass from the vessel
% into the lower part of the coffee pot, excepting through the filter.
In making coffee or other infusions, the materials (previously mixed or
otherwise) are put into the vessel 9, and the liquid portion in passing
through the filter to the lower part of the coffee pot is deprived
of suspended particles and rendered clear. The last described appli-
ention of the said Invention is sometimes modified, as shown in
vertical section in Figure 6, that is to say, instead of screwing the
filter in its place, the tube we, at its bottom is made taper, so as to fit
tightly in the bottom of the vessel a, and a strong handle y, is fixed

page_text: on the top of the frame z, of the filter, to facilitate the removal
of the filter. The said Invention is sometimes modified in other
ways, which, however, I do not consider it necessary particularly
to describe; for example, the filtering tube, Figures 2, and 3, may
be open at both ends, and the said ends connected with taps at opposite
sides of the reservoir, in which it is placed, so that the water or liquid
may be drawn off at two places; and when, as in filtering water which
has a fetid odour, it is wished to cause the filtration of the same
through powdered charcoal or other powder, the said charcoal or other
powder is placed between two filtering tubes, one within the other; or,
where the height of the filtering vessel is less than its diameter, as in
the modifications, Figures 4, 5, and 6, a filtering tube or vessel of more
than twice the height of the framic may be used, and tied at its middle
on the collar, and the half of the tube or vessel below the said collar
turned up, and the charcoal or other powder placed between the double
walls or sides of the filtering tube or vessel.
Having now described the nature of the said Invention, and the
manner in which the same is to be performed, I wish it to be under-
stood that I do not limit myself to the precise manner of carrying the
said Invention into effect, herein described, and represented in the
accompanying drawing, as the same may be varied without departing
from the nature of the said Invention; but I claim the construction of
apparatus for filtering liquids by the use of tubes or vessels of felt or
other flexible filtering material or fabric, supported internally by coils
or frames of wire or other suitable material.
In witness whereof, I, the said Peter Armand Le Comte de
Fontainemorcau, have hereunto set my hand and seal, this
Sixteenth day of August, in the year of our Lord One thousand
eight hundred and fifty-throo
L' DE FONTAINEMOREAU. (L.S.)
