Improvements in Filters and Taps, and the application of same to
Domestic and similar purposes.
I, HARRY BARRAND, of 18, Thrum Hall Lane, Halifax, in the County of York,
Plumber, 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 object of my invention is to construct filters for domestic and similar
purposes, whereby the filtration of the water is rendered more efficient, and all.
impurities contained therein removed. Also by my arrangement or construction
of tap, the said filter. may either be employed for drinking purposes, or, when
water is required for domestic purposes the same passes through an ordinary
adjustable elbow pipe screwed into the tap for this purpose, in drawing water for
domestic purposes the flow has a tendency to remove the impurities adhering to
the filtering material. When it is required to clean out the filter, and supply
new filtering material, the tap is closed and the filter removed for this purpose
without having to turn the water off at the main.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation in section of my improved filter and tap.
Fig. 2 is a side elevation of Fig. 1.
Fig. 3 is a back view in section of my improved filter.
Fig. 4 is a plan of Fig. 3, also in section.
I construct my filter in the form of two cylinders A, B, one within the other,
and having an open end, the inner cylinder B, being cast to or fitting against the
top of the outer cylinder, at the top of the outer cylinder and at one side, is the
outlet pipe or nozzle C, and at the top of the inner cylinder at the opposite side
to the outlet pipe in the outer cylinder, is an opening D, communicating with the
chamber formed between the two cylinders; this chamber is divided into two
compartments E, F, by means of midfeathers or partitions F1, which pass down
to within a short distance of the bottom of the filter, and so leave openings G
for the water to pass from compartment E to compartment F.
The open end of the filter rests upon a rubber or other. packing ring H, within
a suitable recessed flange J, this ring and flange form the bottom of the com-
partments E, F, the flange J is cast upon the body of the tap K, the spindle L
of which passes up through the body of the filter, at the top of which is also
formed a stuffing box M, this spindle is operated as desired by handle N, held
in position by nut P; at the other end of this valve spindle L is a screwed boss R,
working within a similar threaded bush S upon the body of the tap, below the
screwed boss is a conical rubber or other washer T, which, when the valve is
closed, rests upon the conical seating U.
By this construction of valve its durability is greatly increased, no leakage
is possible and a renewal of the washer is easily and quickly effected.
Below this valve I may also employ the ordinary bottom valve V.
At the back of the tap and cast upon same is a screwed stud W, upon which is

page_text: an internally threaded flanged collar W, working within this collar is another
flanged stud X, this flanged stud being attached to the wall for supporting
the filter in a fixed and rigid position, and may be adjusted by the aforesaid
studs W and X and collar W₁ according to the distance it is from the wall or
ceiling.
At the opposite side I form a plug Y which when water is required for domestic
purposes, is removed, and an elbow pipe or nozzle Z attached, the valve T having
been previously closed for this purpose, upon the opening of this valve the water
rushes through the pipe Z and creates a kind of vacuum within the filter, so
cleansing the filtering material from any impurities therein.
When requiring to renew the filtering material within the filter, the valve T
is closed, the bolts Z unscrewed, and handle N taken off, the filter may then be
removed, cleaned out, and replaced without any inconvenience, or having to
turn the water off at the main.
The action is as follows:-Upon the valve T being opened; water passes up
through the filtering material to the top of the inner or smaller cylinder B,
then through the opening 1) into compartment E, the water then passes down
and through the openings G before it enters compartment F', and it still has to
traverse the whole length of this compartment before it passes out through the
outlet pipe or nozzle C; by these means the passage of the water through the
filtering material is three times the length of the filter itself, and the advantages
will be instantly apparent. Also by this construction of tap and valve, the filter
is easily and quickly cleaned, and where desired, the filter may be used apart
from the tap or valve K, by having a nipple formed or attached to bottom of
such filter, which in this case is closed, and an ordinary rubber pipe employed
from the water tap to such nipple for the supply.
Having now particularly described and ascertained. the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
--
1. In filters and taps and the application of same to domestic or similar pur
poses, constructing the filter of two or more cylinders A, B, one within the
other, dividing the annular chamber between the said cylinders into compart-
ments E, F, by midfeathers or partitions F1, openings D, G, to allow of the
circulation of the water from one compartment to the other before passing to
the outlet pipe or nozzle, and attaching the said filter to a tap K whose valve
spindle L (to which is fixed a taper or conical plug T operating on a conical or
taper valve seat U) passes up through the filter, and is operated by handle N,
in the manner and for the purposes, substantially as shown and described.
2. In filters and taps and the application of same for domestic or similar
purposes, the construction of filters with two or more cylinders A, B, one within
the other, the space between which being divided into compartments E, F, and
the water circulating from one compartment to the other, such filter being
attached to a tap having a valve spindle L, conical plug or washer T, valve
seating S, adjustable plug Y and elbow pipe or nozzle Z, operating in the manner
and for the purposes, substantially as shown and described.
3. In filters for domestic and similar purposes, constructing such filters with
an inner and outer chamber or cylinder A, B, the space between which forms
an annular chamber which is divided into two compartments E F, by means
of midfeathers or partitions F, the water from the supply passes up the inner
cylinder or chamber B, through opening D into compartment E, and from
thence through openings G into compartment F, and up through the outlet pipe
or nozzle, in the manner and for the purposes, substantially as set forth.
4. In filters for domestic and similar purposes, constructing filters of any
number of cylinders, one of less or larger diameter than the other, placing such
cylinders one within the other and dividing the annular spaces, between each,

page_text: with suitable openings from one compartment to the other, in the manner and
for the purposes set forth.
5. In filters and taps and the application of same to domestic or similar pur-
poses, constructing such filters and taps so that the filter can be cleaned out and
the filtering material renewed if required, in the manner set forth.
