IMPROVEMENTS IN THE CON- STRUCTION OF WATER FILTERS
Year: 1885

page_text: I, PICKLES PARKER, 9 Church Green, Keighley, Yorkshire, Filter Maker do
hereby declare the nature of my invention for IMPROVEMENTS IN THE CON-
STRUCTION OF WATER FILTERS, to be as follows:-
.
The object of my invention is to construct a water filter in such a manner that
the whole of its contents may easily be removed for the purpose of cleansing or
renewing them.
This I accomplish by forming on the inner surface of the filter's cistern a suitable
number of vertical ribs, which extend the required distance upwards from the
bottom and carry loosely a porous plate upon which rests, also loosely, the whole of
the filtering substances, such as granulated charcoal etc. And in order to prevent
the water from evading these filtering substances by flowing through the openings
that exist between the edge of the porous plate before named and the side of the
filter's cistern, I place around the upper edge of the said porous plate a thin strip of
cork, india-rubber, asbestos or other such material, which when pressed by the
weight of the filtering substances before named, into or to cover these openings,
makes them watertight and so accomplishes the object desired.
It will be readily understood that instead of forming vertical ribs, made to
extend from the bottom upwards so as not to form any corners for the accumu-
lation of dirt, small projections, tapering downwards but shouldered at the top,
placed at a suitable distance from the bottom of the filter's cistern, may be used.
To ensure better fitting of the internal plates in connection with my invention,
I place the vent tube of the filter outside the cistern.

I, PICKLES PARKER of 9 Church Green, Keighley in the County of York do
hereby declare the nature of my invention for IMPROVEMENTS IN THE CON-
STRUCTION OF WATER FILTERS, 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 my invention is to construct a water filter in such a manner that
the whole of its contents may easily be removed for the purpose of cleansing or
renewing them, and in order that my said invention may be clearly understood
I hereunto attach a sheet of drawings illustrative thereof, wherein fig. 1 is sectional
side elevation and fig. 2 sectional plan, while fig. 3. is a sectional side elevation
shewing a further modification of same. The said drawings bearing figures and
letters of reference of which use is made in the following description. On the
inner surface of the filter's cistern A are formed a suitable number of vertical
ribs a, which extend the required distance upwards from the bottom b of the filter
and carry loosely a porous plate c upon which rest, also loosely, the whole of the
filtering substances, such as granulated charcoal eto. d. And in order to prevent
the water from evading these filtering substances d by flowing through any
openings that may exist between the edge of the porous plate cand the side of
filter's cistern A, I place around the upper edge of the said porous plate ca thin
strip of cork, india rubber, asbestos or other such material f which when pressed by
the weight of the filtering substances d, into or to cover these openings, makes the
same watertight, and so accomplishes the object desired. It will readily be under-
stood that instead of formning vertical ribs as shown by fig. 1. a, made to extend
from the bottom upwards so as not to form any corners for the accumulation of
dirt; small projections g, (fig. 3) tapering downwards but shouldered at the top,
placed at a suitable distance from the bottom of the filter's cistern A, as shewn by
fig. 3; may be used..
To ensure better fitting of the internal plates in connection with my invention,
I place the vent tube h on the outside of 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. The construction of a water filter with vertical ribs a used in the manner and
for the purpose as herein described and illustrated.
2. The combination of a porous plate c and a strip of material f with vertical
ribs a used in the manner and for the purpose as herein set forth and described.
3. The construction of a water filter with projections g used in the manner and
for the purpose as herein described and illustrated.
4. The combination of a porous plate c and a strip of material f with pro-
jections used in the manner and for the purpose as herein described and
illustrated.
