page_text: LETTERS PATENT to Samuel Norton, of the Firm of Norton and
Company, of Stockport, in the County of Chester, Patentees'
Manufacturers, for the Invention of "AN IMPROVED AND COMBINED
"
Sealed the 15th September 1870, and dated the 29th June 1870.
PROVISIONAL SPECIFICATION left by the said Samuel Norton at
the Office of the Commissioners of Patents, with his Petition, on the
29th June 1870.
I, SAMUEL NORTON, of the Firm of Norton and Company, of
Stockport, in the County of Chester, Patentees' Manufacturers, do hereby
declare the nature of the said Invention for "AN IMPROVED AND COMBINED
HYDRAULIC FILTER AND DOUBLE VALVE TAP," to be as follows:-
The object of this Invention is to construct a double valve tap from
which water or other liquid may be drawn off direct in a filtered or
unfiltered state, and consists of a tap or cock having two compartments
each fitted with a valve and ordinary screwed spindle and handle, one of
such compartments opening into an ordinary bib or pipe, and the other
leading to a filter of peculiar construction, herein-after described, through

page_text: which the water or other liquid is drawn and thereby filtered. This
filter consists of a vessel, by preference of a cylindrical form, constructed
of sheet copper, or any other suitable cast or sheet metal, glass, or
earthenware, inside which and between perforated diaphragms filtering
material is placed, such filtering material consisting of layers of sponge,
charcoal, sand, or other suitable filtering substance or compound, the
thickness of such layers depending upon the pressure of the water or
other liquid requiring to be filtered. This filtering vessel may also be
connected to any ordinary pipc, cock, or valve.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Norton in the Great Seal Patent Office on
the 29th December 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
NORTON, of the Firm of Norton and Company, of Stockport, in the
County of Chester, Patentees' Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of June, in the year

calendar months next and immediately after the date of the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said Samuel Norton, do hereby declare
the nature of my said 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 this Invention is. to construct a double or treble valve
tap from which water or other liquid may be drawn off direct in a
filtered or unfiltered state, and consists of a tap or cock having two or
more compartments each. fitted with a valve and ordinary screwed spindle
and handle, one of such compartments opening into an ordinary bib or
pipe, and the other leading to a filter of peculiar construction, herein.
after described, through which the water or other liquid is drawn and
thereby filtered. This. filter consists of a vessel, by preference of a
cylindrical form, constructed of sheet copper, or any other suitable cast
or sheet metal, glass, or earthenware, inside which and between, per-.
forated diaphragms filtering material is placed, such filtering material
consisting of layers of sponge, charcoal, sand, or other suitable filtering
substance or compound, the thickness of such layers depending upon the
pressure of the water or other liquid requiring to be filtered. This
filtering vessel may also be connected to any ordinary pipe, cock, or,
valve..
In order that the nature and object of my said Invention may be the
more readily seen and understood, I have hereunto annexed a Drawing,
illustrating two modifications of the same, drawn to a scale of about.
half size.
Fig. 1 is a front exterior view of a combined hydraulic filter and
double valve tap, constructed according to this Invention; Fig. 2 is a
side view of Fig. 1, shewing the filtering vessel in section, and Fig. 3
is a sectional plan of Figs. 1 and 2, showing the disposition and internal
arrangement of the valves in the double valve tap; Fig. 4 is. a front
view; Fig. 5, a side view; and Fig. 6, a plan (all partly in section) of
another modification of valve tap to be used in conjunction, with a
filtering vessel in accordance with this Invention.. Similar letters refer
to similar parts throughout the several views.
In Figs. 1, 2, and 3, A is the body of the tap or cock, which is of a
construction peculiar to this. Invention being internally divided into two
compartments B and C (seen in Figs. 3) both communicating through
their respective apertures D and E with the one common tail or supply
pipe F. The apertures D and E are opened and closed at pleasure by

page_text: the leather covered valves G and H which are each actuated in the
ordinary manner by their respective screwed spindles I and J worked by
the handles K and L, the valve H being illustrated on Fig. 3 as closed,
whilst the valve G is shewn open. The compartments B is open to the
spout or nozzle M as seen in Fig. 3, and the compartment C commu-
nicates with the interior of the filtering vessel N through the branch
pipe O. The filtering vessel N is screwed upon the branch pipe O, and is
constructed of sheet or cast metal in two parts screwed together, as
illustrated at P, in order to afford ready access to the interior, and thus
to enable the filtering material contained within it to be cleansed or
changed as occasion requires. In this filtering vessel layers of filtering
material are placed separated by the loose perforated diaphragms Q, the
top and bottom layers consisting by preference of sponge marked R, and
the intermediate layers being formed of sand S, and powdered charcoal T,
or other suitable filtering material. The filtered water or other liquid is
drawn off from this filtering vessel through the perforations U formed
through its lowest extremity.
The method of using this combined hydraulic filter and valve tap
may be thus described :-The supply pipe F being connected to the
water supply and the water being required to be drawn off unfiltered, all
that is necessary is to turn the handle L, when the valve H will be raised
off its seating and thus allow the water to enter the compartment C
through the aperture E, from whence it will escape and flow through
the spout or nozzle M. If on the other hand it is required to draw off
the water in a filtered state, the handle K must be turned, when the
valve G will open and allow the water from the common supply pipe F
to enter the compartment B through the aperture D, and thence it will
the
pass through the branch pipe O into the filtering vessel N, pressure
upon the water will then cause it to pass speedily through the filtering
material, whereby it will be seperated from all impurities and escapes
in a filtered state through the perforations U formed through the lower
extremity of the filtering vessel N. The speed at which the filtered
water may be drawn off will depend upon the pressure of the supply and
also upon the thickness of the layers of filtering material, through which
it has to pass. In Figs. 4, 5, and 6, a is the body of the tap or cock,
which is also of a construction peculiar to this Invention, being internally
divided into two compartments b and c (the latter shewn dotted in Fig. 4),
communicating through their respective apertures d and e (the latter

page_text: shewn dotted in Fig. 4) with a common central or third compartment ƒ,
which is open to the one common spout or nozzle g, and is provided with
a valve worked in the usual manner by the handle i and screwed
spindle j, such valve being arranged to cover the aperture k, which
communicates with the tail pipe 1. The two other compartments b and c
open respectively into the tail pipes m and n, which tail pipes are
arranged with union joints as illustrated, in order to facilitate their
connection with the supply pipes to which they are joined, and such
compartments communicate with the central compartment ƒ through
their respective apertures d and e, covered by the ordinary leather valves,
o being the handle for actuating the valve which covers the aperture in
compartment b, and p the handle for actuating the valve covering the
aperture in compartment c.
The method of fixing and using this construction of tap or valve is as
follows:-Either of the tail pipes may be connected to the perforated
extremity of the filtering vessel, herein-before described in reference to
Figs. 1, 2, and 3, by means of an union joint, or in any other convenient
manner, the other end of the filtering vessel being attached to the water
supply.
Now for the sake of illustration we will suppose that the tail pipe m is
thus connected to the filtering vessel, the central tail pipe / may then be
connected to an ordinary cold water supply, and the other tail pipe n to a
hot water supply. If it is then required to draw off filtered water, the
handle o will be turned, thus raising the valve off the aperture & which
opens a communication with the central compartment f and allows the
filtered water to flow through the common spout or nozzle g. If hot
water is required the handle p should be turned, thus opening the valve
in compartment c and allowing the hot water from the tail pipe n to flow
into the central compartment f, from whence it will escape through the
common spout or nozzle g. Again, if ordinary cold water is needed, the
handle is to be turned, when the cold will enter the central com-
partment through the aperture k, and then find its way through the
same common spout or nozzle g. It will be readily apparent that the
filtering vessel might be connected to this description of tap or cock in
various ways, so as to dispense with one of the tail or supply pipes, and
thus draw of the filtered water direct from the filtering vessel, the same
as in Figs. 1, 2, and 3. This is accomplished by altering the internal
arrangement of one of the side compartments by making it communicate

page_text: with the central tail pipe instead of the central compartment f; and
fixing the filtering vessel in the place of the tail pipe. which has thus
been dispensed with.
A modification of this Invention is useful for supplying baths, wash-
basins, or similar receptacles with hot and cold water, or for supplying
various liquids through one common spout.
What I claim as my Invention and desire to secure by Letters. Patent
is, the combination and arrangement of a filtering vessel and valve tap,
fitted with two or more valves as and for the purposes described.
2nd. The arrangement and construction of treble valve tap, herein- 1
before described in reference to and illustrated by Figs. 4, 5, and 6, as
and for the purposes described.
In witness whereof, I, the said Samuel Norton, have hereunto set
my hand and seal, this Twenty-seventh day of December, in
the year of our Lord One thousand eight hundred and seventy.
