PROVISIONAL SPECIFICATION.
Improvements in the Construction of Water-filters.
I PICKLES PARKER of 29 North Parade Bradford in the County of York,
Filter Manufacturer do hereby declare. the nature of this invention to be as
follows, that is to say :-
It relates to improvements in the construction of water-filters and consists of
forming these said filters in such a manner that the filtering medium may be
readily removed therefrom, while all the parts are accessible for cleansing
purposes.
I attain the object of this invention by attaching to the walls of the filter's
cistern at an appropriate distance from the bottom thereof a flange that I arrange
to project inwardly at a suitable angle to said walls, but preferably so that same
slightly falls towards the central part. A central opening is left in this flange, and
the edge of same surrounding this opening, is made to receive a loose partitioning
plate as well as an annular piece of cork both of which are made to fit tightly into
so as to cover said opening in the flange.
Axially in the partitioning plate is formed a small pipe, or projection having an
opening made longitudinally through it, and said pipe may be arranged to project
downwardly as well as upwardly from said plate, although in most cases the latter
part only need be employed.
.
A bell-shaped cover is made to fit loosely over the upwardly projecting part of
this pipe above and around which the filtering material (as animal charcoal etc.).is
placed so that any water that passes through said filtering material is made to pass
beneath the lower edge of the bell-shaped cover and the plate upon which it rests
from which, said water, passes through the opening in the vertical pipe, into the
cavity beneath. By the cover resting upon the plate as above described any
particles of the filtering material that may be washed or caused to move by said
water, are arrested and prevented from passing this joining place.

COMPLETE SPECIFICATION.
Improvements in the Construction of Water-filters.
I PICKLES PARKER of 29 North Parade Bradford in the County of York,
Filter 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, that is to say:
:-
It relates to improvements in the construction of water-filters and consists of
forming these said filters in such a manner that the filtering medium or materials
may be readily removed therefrom leaving all the parts accessible for cleansing
purposes.
In the accompanying sheet of drawings Fig. 1. represents a section side view of
a water filter made in accordance with my invention, and Fig. 2 is a view in detail
enlarged scale, shewing certain of the parts.
I attain the object of my invention by attaching to the walls a of the filter, at an
appropriate distance from the bottom thereof, a flange b, which I arrange to project
inwardly at a suitable angle to said walls a, but preferable so that the upper surface
thereof will slightly fall towards the central part.

page_text: A central opening is made in this flange band its edge surrounding this
opening is made to receive a loose partitioning plate e as well as an annular piece
of cork d both of which are made to fit tightly into so as to cover said opening in
the flange, or in place of the cork d a piece of asbestos cloth entirely covering the
under surface of the plate e as also the peripheral rim thereof in order that when
the said plate c, having this cloth thus covering, it is tightly pressed or fitted into
the opening it is perfectly water tight all round.
Axially in the partitioning plate e is formed a small pipe e or projection having
an opening made lengthwise through it, and said pipe e may be arranged to project
downwardly as shewn in broken lines (in order to assist the siphoning action for
drawing the water into the part ¹) as well as upwardly from said plate e although
in most cases the latter part only need be employed.
A bell-shaped cover fis made to fit loosely over the upwardly projecting part of
this pipe e, above and around which the filtering material (as animal charcoal etc.) g
is placed, so that any water that passes from the part / through the material g into
the part is made to pass beneath the lower edge of the said cover f, as indicated
by the arrows. By the cover resting upon the plate c as above described any
particles of the filtering material that may be washed or caused to move by the
percolation of said water are arrested and prevented from passing this joining
place.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. In a water-filter the combination of a partitioning plate with a vertical pipe
and a bell-shaped cover to fit over same together with a flange formed in said filter
for holding said plate as described, all these parts being formed and arranged to
attain the object desired substantially as herein specified.
