We POMFRET HIKELY of "The Baths," Manager and JOSEPH RADCLIFFE of
42 Taylor Street Assistant at Water Works, both of Rochdale in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
The improved filter is applicable to the ordinary supply or delivery pipe and is
intended for use either under high or low pressure, it can also be fixed on the suction
or delivery pipe of a pump.
It consists of four principal parts, namely, the body or case for holding the
filtering slide, the slide, the cover, and the arrangement for tightening the cover
when fixed on the top flange of the body above the slide.
The body or outer case is intended for holding the slide (containing the filtering
material) in position and is provided with two sets of grooves, either vertical or
nearly so, for the flanges of the slide to work in, and is contracted at each end to the
size of the pipe required and formed with flanges for attaching it thereto.
The slide is made of metal, the back and front being made of either perforated
metal or formed of rods or wires and having a sheet of asbestos cloth for holding the
filtering or purifying material in position.
It is fitted with flanges working in the grooves in the body.
The filtering material contained in the slide may be animal charcoal, block carbon,
spongy iron, or other suitable filtering or purifying medium.
The cover is provided with two grooves which (when the cover is fixed) form a
continuation of those in the body for holding the slide, and with a washer of india
rubber or other compressible material form a water tight joint, to prevent any liquid
from passing excepting through the slide.
The arrangement for fixing the cover is a kind of bridge-piece having a central
nut and four arms which are hooked and terminate beneath the flange of the top part
of the body.
Through the central nut passes a serew which is turned by a hand wheel, and the
lower end of such screw presses tightly upon the cover and holds it firmly in its
place.

page_text: We POMFRET HIKELY of "The Baths" Manager, and JOSEPH RADCLIFFE, of
42 Taylor Street, Assistant at Water Works, both of Rochdale in the County of
Lancaster 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 :-
The improved filter is applicable to the ordinary supply or delivery pipe and is
intended for use either under high or low pressure; it can also be fixed on the suction
or delivery pipe of a pump.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the two sheets of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on Sheet 1 is a vertical longitudinal section of our improved filter.
It consists of four principal parts namely the body or case for holding the filtering
slide, the slide, the cover and the arrangement for tightening the cover when fixed on
the top flange of the body above the slide.
The body or outer case a, a is intended for holding the slide b,b (containing the
filtering material c, c) in position and is provided with two sets of grooves not seen
at Fig. 1. but shown at d, d on Fig. 2. hereafter referred to either vertical or nearly
so, for the flanges b₁, of the slide b, b to work in, and is contracted at each end as
seen at a', a¹ to the size of the pipe required and formed with flanges e, e for attaching
it thereto.
The slide b, is made of metal, the back and front being made of either perforated
metal or formed of rods or wires and having a sheet of asbestos cloth f, ƒ for holding
the filtering or purifying material c, e in position.
It is fitted with flanges ; working in the grooves d, d in the body a, a.
The filtering material c, c contained in the slide b, may be animal charcoal, block
carbon spongy iron, or other suitable filtering or purifying medium.
The cover g, g is provided with two grooves which (when the cover is fixed) form a
continuation of those in the body for holding the slide b, band with a washer h, h of
india rubber or other compressible material form a water tight joint to prevent any
liquid from passing excepting through the slide b, b.
The arrangement for fixing the cover which we employ for small filters is a kind of
bridge-piece i, Fig. 1. having a central nut and four arms 1,1 (two of which only are
shown on the drawing) which are hooked and terminate beneath the flange of the top
part of the body a, a.
Through the central nut passes a screw mm which is turned by a hand wheel n, n
and the lower end of such screw-presses tightly upon the cover g, and holds it firmly
in its place.

page_text: On sheet 2 of the drawings Fig. 2. is a vertical section and Fig. 3. a plan view with
the cover removed of a modification of our improved filter which we consider to be
best adapted for filters of a larger size.
In this one at the top and the other at the bottom.
instead of forming the inlet as the previously described Fig. we form
two branches
Each pipe of which these are attached is provided with a valve or tap. In ordinary
use the upper one a" is open and is the inlet for the water to be filtered; the lower
one a being kept closed.
When it is required to flush or cleanse the inlet side of the slide, the tap or valve
of the lower pipe a is opened, and the water flushes through, thoroughly cleansing
the exterior of the slide without removing it or the cover. For smaller filters the
slide b, b is simply removed and washed.
For large covers we also find it better to have four hinged bolts o, o with lever
nuts P. P. for the purpose of fixing the same instead of the arrangement of hooked
bridge piece and screw, shown and described with reference to Fig. 1.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
The combination of the body, filtering slide, cover and means for fixing the same,
constructed arranged and operating substantially as hereinbefore described and
illustrated by the drawings annexed.
