I NATHAN GOLD KIMBERLEY Engineer Springfield Road New Southgate
Middlesex do hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to that class of filtering apparatus
wherein the liquid passes under pressure through the filtering medium into a receiver
and from which it is drawn as required.
The apparatus consists of a chamber preferably cylindrical inside containing
the filtering medium which may be compressed between perforated plates by means
of a screw passing through one or both of the perforated plates provided with a
mut or by a screw passing up the centre of the base of the chamber operated an.
locked from the outside of the chamber or by other suitable means.
A. block of carbon or other porous substance forming the whole or a portion of
the filtering medium may be placed in the chamber, or, the filtering medium may
be contained in a separate case and placed inside the chamber and attached to the
outlet in a suitable manner to ensure the liquids passing through the filtering
medium on its way to the receiver.
This filtering chamber is supported by a base or bracket or other connection
suiting the position in which the apparatus may be placed and is provided with
an opening at its lower part to connect to the pipe conveying the liquid to be
filtered and another opening at top where it is connected to a receiver into which
the filtered liquid passes and from which it is drawn off as required through a pipe
fixed at base of receiver or to the connecting passage between the filtering
chamber and receiver or by other suitable means; the passage of the liquid from
the body of the filter into and out of the receiver may be controlled by a cock or
valve fixed in the connector or the drawing off tube or both.
When it is desired to utilise the apparatus for the delivery of a measured quantity
of liquid the receiver can be made of transparent glass graduated to indicate any
quantity of liquid contained in the receiver, or, the receiver may be made of metal
or other opaque material having a separate gauge glass or measuring vessel fixed
to the side or otherwise connected to show the level of the liquid in the receiver
and enable any desired quantity of the liquid to be drawn off.
The quantity of liquid contained between the cock or valve in the connector and
the first division of the graduated scale of the receiver or measuring vessel may be
regulated by a plug screwing into a chamber formed in or on the connector or by
other suitable means.
The receiver and measuring vessel may be provided with a valve for the entrance
or escape of air.

I NATHAN GOLD KIMBERLEY Springfield Road, New Southgate in the County
of Middlesex Engineer, 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 more particularly to that class of filtering apparatus
wherein the liquid passes under pressure through the filtering medium into a
receiver and from which it can be drawn as required.
In order to more clearly explain and illustrate the manner in which my invention
is carried into effect I annex hereto a sheet of drawings in which Fig. 1 represents
a vertical section of my improved filtering apparatus suitable for fixing on
counter or other support.
a
Fig. 2 shows my improved combined filtering and measuring apparatus with
bracket for fixing to a wall or other support.
The apparatus consists of a chamber A preferably cylindrical inside to contain
the filtering medium which may be compressed between perforated plates by means
of a screw passing through one or both of the perforated plates provided with a
nut on turning which the perforated plates will be drawn nearer to each other or by
a screw B passing up through the centre of the base C of the chamber A acting
against the underside of the perforated plate D operated from the outside of the
chamber and provided with lock nut E to hold the screw B in position as well as
to provide against leakage or by other suitable means.
A block of carbon or other porous substance forming the whole or a portion
of the filtering medium may be placed in the chamber A (see Fig. 1) any space
remaining between the block F and perforated plate D will be filled with loose
filtering materials or the filtering block may be entirely dispensed with as shown
in Fig. 2 when the whole space between the perforated plates D. G. will be filled
with suitable filtering materials or the filtering medium may be contained in a separate
case fixed inside the chamber A in a suitable manner to ensure the liquid passing
through the filtering medium on its way to the receiver.
This filtering chamber A is supported either on a stand as at C Fig. 1 or by a
bracket as at H Fig. 2 or other connection suiting the position in which the
apparatus may be placed and is provided with an opening I at its base to connect
to the pipe conveying the liquid to be filtered and another opening J at top where
it is connected to the receiver K into which the filtered liquid passes and from
which it can be drawn off as required through the pipe L fixed at base of receiver
or to the connecting passage between the filtering chamber and receiver or by other
suitable means. The passage of the liquid from the body of the filter into and out
of the receiver may be controlled by a cock or valve M fixed in the connector N
or the drawing off tube L or both.
When it is desired to utilise the apparatus for the delivery of a measured
quantity of liquid the receiver K can be made of transparent glass graduated to
indicate any quantity of liquid contained in the receiver or the receiver may be
made of metal or other opaque material having a separate gauge glass or
measuring vessel fixed to the side or otherwise connected to show the level of
the liquid in the receiver and enable any desired quantity of the liquid to be 4
drawn off.
The quantity of liquid contained between the cock or valve M in the connector
and the first division of the graduated scale of the receiver or measuring vessel K
may be regulated by a plug screwing into a chamber formed in or on the connector
or by other suitable means.

page_text: The receiver and measuring vessel K will be provided with a valve for the
entrance or escape of air.
Two forms of valves suitable for this purpose are
shown.
The valve shown in Fig. 1 is actuated by pressing down the knob O until the
valve P is moved off its seat when the air passages through the body of the valve
will be opened and any variation of pressure of the air inside and outside the
receiver will pass into equilibrium and on the pressure being removed off the knob ()
the valve under the action of the spiral spring Q will close itself.
The air passage through the body of the valve shown in Fig. 2 is opened to the
atinosphere by unscrewing the cap R and by screwing the cap R on to its scat the
air passages through the body of the valve and cap are closed.
Having now described the nature of my invention and shown how the same may
be carried into effect I declare that what I claim is
1st. The filtering apparatus consisting of a chamber to contain the filtering
medium through which the liquid passes under pressure on its way to the connector
and the receiver from which it can be drawn as required the receiver being provided
with an air valve substantially as herein described and illustrated at Fig. 1.
2nd. The filtering and measuring apparatus consisting of a chamber to contain
the filtering medium through which the liquid passes under pressure on its way to
the graduated receiver from which it can be drawn in the quantity required. The
passages in the connector between the filtering chamber and the graduated receiver
and in the drawing off tube being controlled by a cock or valve and the graduated
receiver being provided with an air valve substantially as herein described and
illustrated at Fig. 2.
3rd. The combination in a filtering apparatus wherein the liquid under treatment
passes through the filtering medium under pressure of a chamber to contain the
filtering materials and a receiver of glass or other transparent substance provided
with an air valve the whole connected together substantially in the manner herein
described and illustrated.
4th. The combination of a filtering chamber with a graduated transparent receiver
for the purpose of filtering liquids under pressure and delivering the same in
measured quantities substantially in the manner herein described and illustrated.
Dated this 28th day of March 1895.
