Improvements in or connected with Filters.
I, BENJAMIN MACKAY, of Windmill Lodge, Minchinhampton, Stroud,
Gloucestershire, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means and apparatus for the clarification and filtration
of liquids.
For the purpose of this invention, I prepare a pail or vessel of a flexible
material which is capable of expansion and collapsing, and use it for the impure
or dirty liquid. This vessel has a cover, and the bottom of rigid material has a
cup like appliance in which cotton wool or other fibrous material is placed and
enclosed by a perforated lid.
The lower part of said cup terminates as a nozzle to which a flexible tube is
affixed for the free flow of the liquid now partially clarified. The opposite end
of the flexible tube is attached to the nozzle of a cylinder, the base of which
is provided with a tap for regulating the flow.
The cylinder is charged with cottonwool or other material and is located
beneath a perforated diaphragm which supports carbon, or other purifying
agent through between the particles or blocks of which the liquid has to percolate
and rise to an outlet or draw off, the liquid being at this stage perfectly clear and
wholesome.
The cylinder is preferably of waterproof canvas, or of closely woven hempen
hose and to facilitate a regular flow of liquid through the apparatus, the height
of the cylinder and outlet to that of the first named vessel can be regulated as
desired, the flow of the liquid being by gravity.

I, BENJAMIN MACKAY, of Windmill Lodge, Minchinhampton, Stroud,
Gloucestershire, Commercial Traveller, 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:-
This invention relates to means and apparatus for the clarification and filtration

page_text: My invention will be understood from the following description aided by the
accompanying drawings which show the apparatus in section.
For the purpose of this invention, I prepare a pail or vessel of a flexible
material A which is capable of expansion and collapsing, and use it for the
impure or dirty liquid. This vessel has a cover B and the bottom of rigid
material has a cup like appliance D in which cotton wool or other fibrous
material E is placed and enclosed by a perforated lid F.
The lower part of said cup D terminates as a union G to which is attached a
tap socket H carrying a flexible tube I for the free flow of the liquid now partially
clarified. The opposite end of the flexible tube is attached to a tap nozzle J
of a cylinder K, which cylinder K has cotton wool or other material L located
beneath a perforated diaphragm M which supports carbon or other purifying
agent N through between the particles or blocks of which the liquid has to
percolate and rise to an outlet or draw-off P, the liquid being at this stage per-
fectly clear and wholesome.
The cylinder K is preferably of waterproof canvas or of closely woven hempen
hose, and to facilitate a regular flow of liquid through the apparatus, the position
of the cylinder K and outlet P is below that of the first named vessel the flow of
the liquid being by gravity.
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 improvements in or connected with filters consisting of a collapsable
bucket carrying a filtering cup having a depending flexible pipe in communica-
tion with a hempen or other cylinder carrying a filtering medium, substantially
as set forth.
2. In filters, providing a collapsable bucket with a cup shaped exit, said cup
containing a filtering medium protected by a perforated cover and communicating
by a flexible tube with a hempen or like cylinder containing a series of filtering
material, the water issuing at the upper part of the second vessel, all substantially
as set forth.
