IMPROVEMENT IN WATER FILTERS
Year: 1885

page_text: We RICHARD ROPER KELLY Chemical Agent and Manufacturer of 3 Pall Mall
East in the County of Middlesex and AGATHA COLUMBA LAURA WEIGEL, Gentle-
woman, married of 43 Brunswick Terrace, Hove, in the County of Sussex do
hereby declare the nature of our invention for AN IMPROVEMENT IN WATER
FILTERS to be as follows:-
Our Invention relates to an improvement in Water Filters for which letters
Patent were granted to us dated 28th May 1885, N° 6505.
Our present invention is an improvement of the apparatus therein described.
The filter is composed of a vessel in the form of an acorn with a nozzle at the
bottom so arranged as to screw into a corresponding nozzle on the top of a supply
clock provided with two taps which latter are so arranged that if both are opened
simultaneously the water from the supply pipe will flow out direct without passing
through the filter and if only the first tap is opened the water will rise upwards
through the said nozzle into the filtering vessel, passing through the various
filter-beds and flow out through a spout at the top.
This acorn shaped filtering vessel is made in two parts, viz: a flat top com-
partment so arranged as to screw on to the top of a lower compartment of 6, 8 or
more times the depth of the upper one.
The filtering beds are arranged as follows i
A body of Charcoal fills the lower compartment up to a perforated metal-plate
resting on a ledge running around the inside of the vessel.-A disc of Carbon paper
or of ordinary filtering paper may be placed underneath the perforated metal-plate
and another one upon it.-An India-rubber washer is next placed on the paper disc
and upon the washer a metal or other ring about or inch, more or less, high
for the purpose of serving as a support for a second perforated metal plate resting
on the top of the ring.
The room between the two perforated metal-plates is filled with Silver-sand or
any other suitable material and on the top of the last metal-plate a layer of
asbestos-fibre is deposited or any other suitable material may be used in accordance
with the Specification of our Patent No 6505 A D 1885.
The top compartment is now screwed on to the lower one and as the former is
provided with a further perforated metal plate near to its open side this latter will
come down closely upon the Asbestos-fibre deposit above described which will thus
be securely supported between two perforated metal-plates.

page_text: We RICHARD ROPER KELLY Chemical Agent and Manufacturer of 26 Suffolk
Street Middlesex and AGATHA COLUMBA LAURA WEIGEL Gentlewoman, married
of 43 Brunswick Terrace, Hove in the County of Sussex do hereby declare the
nature of our invention for AN IMPROVEMENT IN WATER-FILTERS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our invention relates to an improvement in water filters for which letters
patent have been granted to us under date of the 28th May 1885, N° 6505.
Our present invention is an improvement of the apparatus therein described.
A filtering vessel in the form of an acorn as shown in the accompanying
drawing, or of any other suitable form, provided with a nozzle at the bottom is so
arranged as to screw into a corresponding nozzle on the top of a supply water cock
fitted to the supply-pipe.
This cock is provided with two taps so arranged that if both are opened
simultaneously the water will flow out from the supply pipe without entering the
filter and if only the first tap (B in the drawing) is opened, the water will rise
upwards through the filtering beds and flow out by a spout (C) at the top of the
filtering vessel.
This arrangement of taps may be varied by placing tap B on the nozzle of the
supply cock in which case only tap A need be opened if it is desired to draw water
direct from the supply-pipe and only B (on the nozzle) if it is desired to pass the
water through the filter.
:
The filtering vessel is made in two parts, a flat top one to screw on to the lower
compartment containing the different filtering beds.
These beds are arranged as follows 1
The bulk of the lower compartment is filled with granulated Charcoal (I) up to
a perforated metal plate (D) resting on a ledge running round the inside of the
filtering vessel. Underneath this perforated disc, a disc of Carbon paper or of
ordinary filtering paper is placed and a second one on the top of the perforated
plate D. An India-rubber washer is next placed on the latter and upon this a
metal or other ring which serves for the purpose of supporting a second perforated
metal plate E-The room between these two perforated plates is filled with fine
silver sand or other silicious or other suitable material (III in drawing).
On the top of this bed of sand another India rubber washer is placed before
inserting the perforated plate E so as to secure a perfect sealing all round the walls
of the filter.
After the metal plate E has been put in position a layer of fine Asbestos fibre is
deposited thereon or any other suitable material in accordance with the Specifi-
cation of our Patent N° 6505.-The top is now screwed on and as it contains a
further perforated metal plate F firmly fastened to the lower portion of the top-
compartment, this plate F will come down closely to the Asbestos-fibre or other
deposit on the plate E and thus be firmly secured between the two perforated
plates E and F.

page_text: The water entering the filter through the nozzle on the supply cock is driven
upwards by its pressure through the different filtering beds into the open space
over the perforated plate F, whence it is discharged through the spout C.
For the purpose of filtering water without pressure or so called Drip-Filters we
arrange a filter consisting of the same system of filtering-beds as shown above,
fitted to a tank or vessel, containing the water to be filtered, in any convenient
manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
The particular construction of filters shown in the drawing substantially as
shown and described.
