page_text: PICKLES PARKER N° 3 Prospect Place Halifax Road Keighley Yorkshire I do
hereby declare the nature of my Invention for A WATER FILTER to be as
follows:-
The cistern tapers downwards and inwards from top to bottom and is quite
plain and smoothe throughout.
The vent tube is placed outside.
It may be made to any size by taking the diameter at the top at two thirds and
at the bottom at half the depth of the cistern.
It may be made in earthenware, stone, saltware, terra-cotta, porcelean, glass,
china, or from any substance or substances, from which such things are made or
may be made from time to time.
A perforated plate, made from the same material, or from any other material
from which filters are made, or may be made from time to time, or from any other
suitable substance either herein mentioned or otherwise is so sized as to closely fit
the sides of the cistern at about midway between the top and bottom.
On this plate is placed a layer of fine pebbles, about half an inch deep.
Over the pebbles and resting on them is placed a plate about from one and a
half to two inches thick, made from granulated animal charcoal.
On this plate is placed a layer of loose granulated animal charcoal about two
inches deep.
A plate simular to the bottom one but larger is placed on the loose charcoal.
All these plates have a small knob in the centre.
The edges of all the plates and the sides of the cistern are made watertite by
the plates being bordered with, cork, canvas, calico, tape, gutta-percha, indiarubber,
or other simular substance suitable for such a purpose.

page_text: I, PICKLES PARKER of 3 Prospect Place, South Street, Keighley, Yorkshire,
Labourer, Army Pensioner, do hereby declare the nature of my Invention for
A WATER FILTER and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, that
is to say :-
The cistern of the waterfilters to which my Invention is applicable tapers
downwards and inwards from top to bottom and is quite plain and smooth
throughout, but will be better understood by reference to the accompanying
Sheet of Drawings wherein Fig. 1 is a sectional elevation of A the cistern, which
may be of any suitable kind of material.
At a suitable distance from the bottom of the cistern A is made to fit a
perforated plate b which may be of any suitable perforated or porous material-
The edge of the said plate b is made to suit the tapering form of the cistern A in
such a manner as to be watertight; to facilitate which I may encircle the plate b
by any suitable material as cork, indiarubber etc. as shewn at k Fig. 1.
Above and resting on the plate b is a layer of pebbles c (or any other suitable
filtering material) which carries a plate of granulated charcoal & made an appropriate
thickness.
A plate e, similar in shape and for a similar purpose to the plate b, is placed over
the plate d.
All the plates b, d and e have each a small knob 6¹, d' and e' respectively, used
to facilitate the removal of the said plates.
From the foregoing description it will be seen that the plates b, d.and e together
with their intermediate layers can easily be removed for the purpose of cleaning
etc., also that, without departing from the principal part of my said Invention,
the bottom part f and the top part g of the cistern A may be made of any shape
provided that the part of the said cistern A. where the plates b, d and e are placed
is made of the required taper form as illustrated in Fig. 2 which is also a sectional
elevation in which the same letters of reference indicate the same parts; and also
that any number of plates may be used and interceded by any number of layers
of different substances provided that the said plates are made to fit tightly in
the cistern.
In connection with my Invention the vent tube is placed outside the
cistern A.
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. Waterfilters, having their inner sides taper used in the manner and for the
purpose as fully described.
2. The use of loose plates either plain or encircled with cork, indiarubber or
other material in combination with waterfilters having their insides taper in the
manner substantially as fully herein described and set forth.
Dated this 12th day of September 1884.
