Improvements in Filters.
1, GEORGES FOUCHARD, of 51, Avenue de l'Observatoire, Paris, in the Republic
of France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a filter so constructed and arranged as
to be capable of being reversed or inverted, and allow of its being readily cleansed.
Filters according thereto may be mounted in such a manner as to be capable of
being turned about any desired axis. When required, however, they may be fixed
in position.
In the accompanying illustrative drawings,
Figs. 1 & 2 are elevations of a filter according to this invention showing two
positions thereof, one being the inverse of the other; and
Figs. 3 to 6 inclusive illustrate other arrangements hereinafter more fully
referred to.
Referring to Figs. 1 & 2, A B C D is a chamber or vessel which may be of any
suitable form and dimensions and in the interior of which there is arranged a
filtering partition E F G which divides the filter into two compartments.
The outer casing of the filter is formed with two tubular openings H and I, and
is provided with glazed sight-holes J & K, to enable the interior to be inspected;
and with other desired accessories. The filter may be quickly connected with
any suitable tap or cock by means of a union L or other suitable means.
the lower part, a tubular attachment M permits of the proper discharge of the
liquid.
At
The filtering partition E F G, which may consist of any suitable material, such
as stone-ware, charcoal or carbon, porcelain, pipe clay, and felt, is firmly fixed
between the two parts of the vessel A B C D in such a manner as to divide the
latter into two compartments which do not otherwise communicate with each other.
As will be seen from Fig. 1, the liquid to be filtered passes through the tubular
opening H, into the upper compartment, then filters through the partition E F G,
and finally passes off through the attachment M.
When the filter has been in use for some time, impurities will have been..
deposited upon the filtering partition E F G, and perhaps have permeated the
material of which the partition is formed. In order to cleanse the filter, the-1
union Lis disconnected, which is very easily done, and the filter is turned upside
down, into the position shown in Fig. 2. If the water be now allowed to flow, it
will first carry off the impurities that bave been deposited upon the filtering
partition E F G. The water is not collected during this cleansing-operation but
is allowed to flow away by removing a waste-plug Z. For this plug may be
substituted if desired a cock or tap serving both as a filtered water tap and as a
flushing-tap. After the lapse of a very short time, the filtering partition will be
perfectly cleansed, and the water passing off at the bottom will be quite pure.
In the operation just described, not only is the exterior of the filtering partition
cleansed, but also all impurities and foreign matters which may have penetrated
into the body of the filtering medium.
When the filtering partition again becomes encrusted with impurities the filter
will be turned back again into the position shown in Fig. 1, and the above described
operation will be repeated.

page_text: From the preceding description it will be seen that in my arrangement of filter,
the cleansing operation is extremely easily and quickly effected; it can therefore
be performed very frequently, consequently perfectly filtered water can almost
always be had.
As above stated, the vessel A B C D which may be of metal or other suitable
material, may be of any desired form. The filtering partition E F G may also be
of any desired form, the only essential condition being that it shall divide the
interior of the filter into two partitions which shall have otherwise no communication
with each other. This filter is applicable to all kinds of taps.
In the arrangement shown in Fig. 3, the water to be filtered enters the filter
through the union N, passes through the filtering partition indicated by dotted
lines, and then flows off through the tap O. A tap P mounted on the pipe to
which the union N is attached, allows unfiltered water to be obtained when desired.
The tap P is constructed internally as illustrated in Fig. 4. In this arrangement,
the filter is capable of moving along in a slot Q and, it may be, turned or
rotated about the trunnions R. This arrangement of filtering fountain may either
be fixed in position or be capable of being inverted. In the arrangement shown
in Fig. 4 also the filter is mounted on the pipe which conveys water to the tap S
that is opened when unfiltered water is required. To put the filter out of operation,
it is necessary merely to close the valve T.
In the arrangement illustrated in Fig. 5, the water to be filtered may be admitted
into the upper or into the lower portion of the filter at will. In this case, the
filtering partition is not constructed as hereinbefore described but is composed of
porous vessels as shown in plan in Fig. 6. The water to be filtered is admitted at
the bottom, passes through the filtering medium, and flows off through the tap V.
U is a flushing tap. When the apparatus is inverted the water flows off at the
plug-hole X into which the tap V is inserted, whilst the hole otherwise occupied
by the tap V is stopped by a plug.

Improvements in Filters.
I, GEORGES FOUCHARD, of 51, Avenue de l'Observatoire, Paris, in the Republic
of France, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to provide a filter so constructed and arranged as
to be capable of being reversed or inverted and allow of its being readily cleansed.
Filters according thereto may be mounted in such a manner as to be capable of
being turned about any desired axis. When required, however, they may be fixed
in position.
In the illustrative drawings filed with my Provisional Specification,
Figs. 1 and 2 are elevations of a filter according to this invention showing two
positions thereof, one being the inverse of the other; and
Figs. 3 to 6 inclusive illustrate other arrangements hereinafter more fully
referred to.
Referring to Figs. 1 and 2 A B C D is a chamber or vessel which may be of any
suitable form and dimensions and in the interior of which there is arranged a
filtering partition E F G which divides the filter into two compartments.

page_text: The outer casing of the filter is formed with two tubular brauches or openings H
and I, and is provided with glazed sight-holes J & K, to enable the interior to be
inspected; and with other desired accessories.
The filter is adapted to be quickly connected with any suitable water supply
tap or cock by means of a union L or other suitable means.
At the lower part,
a tubular attachment M permits of the proper discharge of the liquid.
The filtering partition E F G consists of any suitable porous material, such as
stone-ware, charcoal or carbon, porcelain, pipe-clay, or felt, and is firmly fixed
between the two parts of the vessel ABCD in such a manner as to divide
the latter into two compartments which do not otherwise communicate with each
other: As will be seen from Fig. 1, the liquid to be filtered passes through
the tubular branch H into the upper compartment, then filters through the
partition E FG, and finally passes off through the attachment M.
When the filter has been in use for some time, impurities will have been deposited
upon the filtering partition EFG and perhaps have permeated the material of
which the partition is formed. In order to cleanse the filter, the union Lis
disconnected from the branch H, which is very easily done, and the filter is turned
upside down into the position shown in Fig. 2, the branch I being connected by the
union L to the water supply tap or cock. If water be now allowed to flow into the
inverted filter, it will first carry off the impurities that have been deposited upon
the filtering partition EFG. The water is not collected during this cleansing-
operation, but is allowed to flow away by removing a waste-plug Z.
For this plug
may be substituted if desired a cock or tap serving both as a filtered-water tap and
as a flushing-tap. After the lapse of a very short time, the filtering partition will be
perfectly cleansed, and the water passing off at the bottom will be quite clear.
In the operation just described, not only is the exterior of the filtering partition
cleansed, but also all impurities and foreign matters which may have penetrated
into the body of the filtering medium, will be removed.
When the filtering partition again becomes encrusted with impurities the filter
can be turned back again into the position shown in Fig. 1, and the above described
operation repeated.
From the preceding description it will be seen that in my arrangement of filter,
the cleansing operation is extremely easily and quickly effected; it can therefore
be performed very frequently, consequently perfectly filtered water can almost
always be had.
As above stated, the vessel A B C D, which may be of metal or other suitable
material, may be of any desired form. The filtering partition EFG may also be
of any desired forin, the only essential condition being that it shall divide the
interior of the filter into two portions which shall have no communication with each
other, except through the interstices of the filtering partition. This filter is
applicable for use with all kinds of taps.
In the arrangement shown in Fig. 3, the water to be filtered enters the filter
through the union N, passes through the filtering partition indicated by dotted
lines, and then flows off through the tap O. A tap P mounted on the pipe to
which the union N is attached, allows unfiltered water to be obtained when desired.
The tap P is constructed internally similarly to the tap S illustrated in Fig. 4.
In this arrangement, the filter is capable of moving along in a slot Q and, it may
be, turned or rotated about the trunnions R. This arrangement of filtering
fountain may either be fixed in position or be capable of being inverted.
In the arrangement shown in Fig. 4 also, the filter is mounted on the pipe which
conveys water to the tap S, which is opened when unfiltered water is required.
Το
o put the filter out of operation, it is necessary merely to close the valve T.
In the arrangement illustrated in Fig. 5, the water to be filtered may be admitted
into the upper or into the lower portion of the filter at will. In this case, the
filtering partition is not constructed as berein before described but is compused of
porous vessels as shown in plan in Fig. 6. The water to be filtered is admitted at
the bottour, passes through the filtering medium, and flows off through the tap V.

page_text: U is a flushing tap. When the apparatus is inverted the water flows off at the
plug-hole X into which the tap V is inserted, whilst the hole otherwise occupied
by the tap V is stopped by a plug.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
1. A filter comprising a casing divided into two parts by a filtering partition
composed of suitable porous material, the construction and arrangement being such
that the filter can be readily turned upside down, (or of being rotated about an
axis), so as to permit of its being used in either position, and thereby enable it to
be readily cleaned, the said filter being capable of being adapted or fitted to any
construction of tap, according to requirements, substantially as herein described.
2. My improved filter constructed substantially as hereinbefore described and
illustrated in the drawings referred to.
