Improved Filter.
WILLIAM DALTON Tin and Copper Smith 9 Dickson Road Blackpool Lancashire
do hereby declare the nature of this invention to be as follows:→
A filter constructed in such a manner as to insure the perfect filtration of water
or any liquids, and at the same time to make provision for carrying away the
excreta, or deposit left by the water or liquids filtered.
The filter consists of one or more shells, of any size, shape or dimension the
water or liquids being fed into the inner shell or otherwise by means of a pipe
(marked A) which is wholly or partly perforated, and thence through filtering
layers of gauze, asbestos, charcoal, limestone or any other materials (marked F. E. D)
which may be considered or deemed effective, and thence through a perforated or
gauze cover (marked C) of any material' which may be considered to answer the
purpose, whence it comes between the inner shell and outer shell into the bottom
of the outer shell and so passes out of the filter in a pure state.
The provision for carrying away the excreta or deposit left by the water or
liquid filtered is by a simple arrangement consisting of a tube (marked G) from
the inner shell, which passes through the space between the two shells to a tap or
other outlet on the outside of the filter and so carries away any deposit or excreta
which may have been brought by the water or liquid into the filter, and which has
been separated from it by the action of filtration. Provision is also made for
recharging the filter by a tube (marked S).

Improved Filter.
I, WILLIAM DALTON of 9 Dickson Road Blackpool in the County of
Lancaster Tin and Copper Smith 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 :—
My invention relates to a new or improved filter and consists in constructing a
filter in such a manner as to ensure perfect filtration of the water or other liquids
and to provide a means for easily cleaning or carrying away the impurities or
deposit left in the filter by the water or other liquid.
I will now particularly describe my invention making reference to the drawing
filed with the Provisional Specification, which represents a view in front
elevation-partly in section of one form of filter constructed according to my
invention.
A vessel or container X of any suitable shape and material is closed at its upper
end by means of a cover and may be open or provided with a tap at its lower
end H. Within this vessel or container is placed a second vessel or container Y
closed at both ends, and preferably suspended from the top or cover of the vessel
or container X as shown. Passing through to the bottom of the container Y is a

page_text: tube or pipe B, its upper end A being adapted to receive the pipe delivering the
water or other liquid to be filtered. This tube B at or near the bottom end is
perforated and around or inside these perforations is placed a series of layers of
wire gauze or perforated metallic sheets F having one or more thicknesses of cloth,
asbestos or the like between each layer. Above this and encircling the tube B is a
mass D of charcoal, limestone or other suitable filtering material, and around the
upper portion of the container Y which is perforated is a second series of layers C
of wire gauze or the like, which may also have one or more thicknesses of cloth,
asbestos or the like between each layer. The water or other liquid to be filtered
enters by the tube or pipe B passes through the wire gauze and cloth F or the like
contained in or around the bottom of the tube, thence upward through the filtering
material D' and finally through the wire gauze and cloth or the like C into the
container X from which it may flow or be drawn off as required.
A suitable tube S may be provided for recharging the container Y with filtering
material.
On the bottom of the container Y in communication with the tube or pipe B is a
pipe G passing out through the side of the vessel X and furnished with a tap or
stop-cock g to allow of the impurities-contained in the pipe B-being drawn or
ed off. To assist in this operation the supply is turned on, also the tap or stop-cock g
so that as the water passes through the tube B the impurities are carried off
with it through the pipe G.
It will be understood that the filter may be constructed in many different forms
without departing from the principle of my invention.
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.) A filter constructed substantially as hereinbefore described and shown by the
accompanying drawing.
(2.) A filter so constructed that the water or other liquid is caused to flow upwards
through the filtering material, instead of percolating downwards through the filtering
material as heretofore, as set forth.
(3.) In a filter, of the type claimed by Claim 2, the use of means such as the
pipe G for allowing the impurities to be led or drawn off, as set forth.
