Improvements in and relating to Water Filters and Taps.
I, GUILLAUME STECKEN, of 6, Rue de Vienne, Ostend, Belgium, 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:
1
The present invention concerns a water-filter which can be applied to the spout
of a pump or to any water-cock, giving a very pure water, allowing the use of
filtering matters which cost almost nothing and which can easily be substituted,
and finally, supplied with obstructing apparatuses allowing the water to flow noise-
lessly and without splashing into the recipient destined to hold it.
In the annexed drawing given as an example:
Fig. 1 represents a vertical longitudinal section of the filter.
Fig. 2 shows a vertical section of the obstructing apparatus.
Fig. 3 is a vertical section of a different construction of the obstructor.
The apparatus is essentially composed:
1. Of an elbowed tube A which can be hermetically applied to a cock or a pump,
by means of a rubber washer B fixed on the inside upper part of the tube.
2. Of the filter properly-so-called this being composed of three tubes E E¹ E"
made in such a way as to be able to join one another to form a tube of the same
diameter along its whole length. The tube E has at each end a small sieve M
in very fine wire gauze, or in animal hair. The third tube E has at its mouth
a small disk N to the centre of which a tube T is fixed longitudinally in the middle
of the tube E and extending as far as the end of the tube E", which is closed.
with a lid K screwed to it. The tubes E" and T have their cylindrical surfaces
perforated with holes.
The first tube E is filled with bits of sponge and washed sand; the second E¹
contains washed sand; whereas the annular cylindrical space comprised between
the tube E and the central tube T is filled with pounded charcoal.
The arrangement of the three connected tubes allows the unfitting and easy
cleaning of the filter as well as the easy substitution of the filtering matters.
At the joining parts of the three tubes E, E¹, E two rubber rings S, S¹ are
fixed assuring the water tightness of the joints. On the cyindrical surface of these
rings are helicoidal necks. A rubber ring C is placed at the front extremity of
the tube E. The filter thus constructed is placed in an envelope tube D closed by
a screw threaded lid L, the ring C fixed at the opening of this latter tube ensures
its water tightness; to complete the fitting of the apparatus the horizontal part
of the elbowed tube A is fitted into the ring C.
This being applied to the water flow and the water being admitted into the
filter, it passes first through the first sieve M, then through the bits of sponge O
afterwards through the second sieve M and the sand P and continues into the
tube T after having passed through a third sieve fixed to the centre of the disk N.
From the tube T, the water passes through the charcoal in the tube E" through
the holes in this tube and enters the annular space comprised between the
CD..

page_text: filter E E¹ E" and the envelope tube D, passing along the helicoidal canals of the
coupling rings S, S¹.
A certain number of cocks R¹ R" Ru which may be increased, at libitum,
according to the length of the filter serve to collect the filtered water. The tube D
is provided with hinged feet p.
If we wish to have unfiltered water, avoiding its passing from the water supply
through the filter, the elbowed tube A is supplied with a cock R allowing the water
to flow directly outside of the apparatus. This cock, as well as R1 R R are
provided with an obstructing apparatus. This is composed (Fig. 2) of a metal
tube plated or enamelled, having a shoulder upon which is fixed a wire-gauze
very closely woven also plated and folded several times, or a hair-sieve M¹; on the
tissue a rubber-ring V is placed, allowing the tube F to be hermetically ap lied
to the cock we wish to turn on; the water, coming with a pressure upon the sieve
falls without force and splash, like oil, into the recipient intended to hold it.
A different construction of this obstructor consists (Fig. 3) of a simple rubber
tube of a truncated from, in which the sieve is fixed, as shown in the drawing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A water filter distinguished by three tubes connected so as to form one tube
of the same exterior diameter along its whole length, the first containing bits of
sponge and washed sand, the second washed sand, the third having a central tube
perforated, and around this tube, pounded charcoal through which, after having
passed through the different compartments separated from one another by wire-
gauze or hair sieves, the water passes and escapes by holes made in the cylindrical
side of the third tube forming the filter, to be stored in the annular space comprised
between the filter and its enveloping tube, passing through the helicoidal necks
made in two cuplings S, S' which serve as the water-tight connection of the three
tubes forming the filter, and is collected by several cocks R¹ R R which are
provided with the obstructing apparatus, the filter being joined to an elbowed tube
which is hermetically applied to the supply cock, and also provided with a cock
for supplying non-filtered water.
2. In a water filter claimed in 1) an obstructing apparatus allowing the water
to drop without noise and without splashing however great the pressure may be
upon it when entering the apparatus, distinguished by a tube containing a wire-
gauze or hair sieve and which can be used alone or applied to any cock or pump-
spout.
