Improvements in or relating to Apparatus for Supplying Filtered
Liquids.
I, JOHN ANDERSON MCNAUGHTON 18 Stanley Street Cheetham Manchester
in the County of Lancashire Mechanical Appliance Maker do hereby declare the
nature of this invention to be as follows:-
The object of the present invention is the production of an apparatus (working
under pressure) for the instant and handy supply of water or other liquid in a
filtered condition and a characteristic feature of my invention is the novel manner
and means by which the operating of the apparatus is brought about.
The apparatus (with respect to exterior appearance) I prefer constructing in the
form of a jug. But I wish it understood that I do not confine myself to one form
or shape of vessel as for instance (to outward appearance) the apparatus may take
the form of a decanter or water bottle, and the same may be either plain, engraved,
or otherwise ornamented.
A water-fount for the convenient supply of filtered water, and which we will for
present purposes assume to be constructed in the form of a jug, comprises a base,
and body part with spout and handle, to the top of the said body part is screwed
a cover or lid having studs situate at the sides thereof in order that by unscrewing
the lid easy access may be had to the hereinafter mentioned filtering arrangement,
to the inside of the aforesaid body part and situated near the top thereof is a
contracted part the upper side of which is flat and the inside screwed and adapted
to receive a cylindrical case which contains the filtering medium which is in turn
secured to the inside of the cover of the aforesaid cylindrical case at the outside
and on the top of the cylindrical case cover is situated flat wing studs a few
turns of which (unscrewing the case) affords immediate access to the interior
filtering arrangement for cleaning purposes. Situated at the bottom of the afore-
said body part is the base of the apparatus & located at the lower and inner side
of the base are the screw bolts by which the entire apparatus is secured in position
while in use.
To the upper surface of the aforesaid base is secured the body
portion of a watertight joint and to the bottom of the aforesaid body part of the
jug is secured the conical plug of the aforesaid watertight joint screwed to the
bottom of the body part of the aforesaid joint is the pipe conveying water from
the main. According to my improved and simple method of operating the
apparatus herein referred to, an instant supply of filtered water can be had by
simply placing the hand on the handle of the jug and tipping it in a manner
similar to the ordinary way of pouring water from a jug, and which point is
brought about by the coincidence of the ports in the aforesaid watertight joint.
On the jug being turned back to its perpendicular position the aforesaid ports
are closed. With reference to the aforesaid joint which also performs the part
of a hinge upon which the apparatus works. Instead of the joint being com-
posed of a conical plug fitted into a body portion forming a joint or hinge as
aforesaid.
According to an alternative mode of effecting the same object I may use a disc
valve having two discs with alternating ports, by which method on the jug or
apparatus being tipped partly over for the purpose of drawing a supply of water
or other liquid as the case may be, the aforementioned ports would be brought in
a line with each other, and on the jug being turned back to its perpendicular

apparatus being thereby kept watertight by back pressure from main supply pipe.
With a view to further simplifying description, the apparatus herein referred

by the cylinder containing the filtering medium, passing in through perforations
situated at the side of the cylinder, the liquid is again arrested by the filtering
medium through which it percolates and ascends through openings in the top of the
cylinder case, hence issuing by way of the spout or orifice of the jug or apparatus.
I prefer having the apparatus (with the exception of the filtering medium) com-
posed of metal, but the body or central part may be composed of glass or other
like material, while the remaining parts may be composed of brass or other suitable
metal. I am aware, with respect to domestic and other filtering arrangements
generally, the water or other liquid is made to descend and consequently must
pass through the residue of filtration. But a noticeable feature in my present
invention is that the water is made to ascend from bottom to top of the apparatus,
and to pass through the filtering medium in such a manner that the residue of
filtration falls back into a compartment provided for that purpose & situated at
the inner and lower end of the beforementioned filter cylinder.

Improvements in or relating to Apparatus for Supplying Filtered
Liquids.
JOHN ANDERSON MCNAUGHTON 18 Stauley Street Cheetham Manchester in
the County of Lancaster Mechanical Appliance Maker 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 the present invention the production of an apparatus (working
under pressure) for the instant and handy supply of water or other liquid in a
filtered condition, and a characteristic feature of my invention is the novel manner
and means by which the operating of the apparatus is brought about.
respect to exterior appearance I prefer constructing the apparatus in the form of
With
a jug, but I wish it understood that I do not confine myself to one form or shape
of vessel, as for instance (to outward appearance) the apparatus may take the form
of a decanter or water bottle and the same may be either plain, or engraved, or
otherwise ornamented. An apparatus for the convenient supply of filtered water
and which we shall for present purposes assume to be constructed in the form of a
jug represented in the accompanying drawings whereof Fig. 1 is an elevation,
Figure 2 a section, Figure 3 a sectional elevation of herein described watertight
joint and hinge, and Figure 4 a section of the herein referred to conical plug at
the central or cam portion thereof.
In order that my invention may be readily understood I will proceed to describe
the same with reference to the drawings.
The apparatus herein described comprises a base D' Fig. 2, and body part A*
Fig. 2, with spout C2 Fig. 2, and handle. To the top of the said body part is
screwed a cover or lid Figure 2, having studs N, situated near the top thereof,
in order that by unscrewing the lid easy access may be had to the hereinafter
mentioned filtering arrangement. At the inside of the aforesaid body part and
situated near the top thereof is a contracted part M Fig. 2 the upper side of which
is flat and the inside screwed and adapted to receive a cylindrical case U which
contains the filtering medium P, and which is in turn screwed to the inside of the
cover of the aforesaid cylindrical case. At the outside and on the top of the

page_text: cylindrical case cover are situated flat wing studs h Fig. 2, a few turns of which
(unscrewing the case) affords immediate access to the interior filtering arrangement
for cleaning purposes.
Situated at the bottom of the aforesaid body part is the aforementioned base of
the apparatus, and located at the lower and inner side of the base are the screw
bolts e Fig. 2 by which the entire apparatus is secured in position while in use.
To the upper surface of the aforesaid base is secured the body portion of a water-
tight joint K Fig. 2, and to the bottom of the aforesaid body part of the jug is
secured the conical plug R¹, Fig. 3, and R2 Figure 2. of the aforesaid watertight
joint, secured to the bottom part of the aforesaid joint is the pipe * conveying
water from the main. According to my improved and simple method of operating
the apparatus herein referred to, an instant supply of filtered water can be obtained
by simply placing the hand on the handle of the jug and tipping it in a manner
represented by dotted lines A³, and similar to the ordinary way of pouring water
from a jug, and which point is brought about by the coincidence of the ports in
the aforesaid watertight joint and the simultaneous opening of the valve W, Figure 3,
by engaging with the cam shaped portion L, Figure 4, of the aforesaid conical
plug. On the jug being put back to its perpendicular position the aforesaid ports
are closed and the valve W simultaneously returns to its seat.. With reference to
aforesaid watertight joint which also performs the part of a hinge upon which the
apparatus works. Instead of the joint being composed of a conical plug fitted
into a body portion Fig. 8 & 3, and forming a joint and hinge as aforesaid.
According to an alternative mode of effecting the same object I may use a disc
valve Fig. 5 having two discs W' & Figs. 6 & 7, with alternating ports by
which method on the jug or apparatus being tipped over for the purpose of
drawing a supply of water or other liquid (as the case may be) the aforementioned
ports would be brought in a line with each other as at Fig. 7, and on the jug
being turned back to its perpendicular position the said ports would be turned
out of line with each other as at Fig. 6, the apparatus being thereby kept water-
tight by back pressure from water main. With a view to further simplifying
description the apparatus herein referred to may for present purposes be regarded
as fixed and ready for supplying filtered water. The water passes by way of the
pipe and union secured to the fixed base of the jug, through the joint, then
through the bottom of the body part of the jug, and is then arrested by the
cylinder containing the filtering medium passing in through perforations J situated
at the side of the cylinder. The water is again arrested by the filtering medium
through which it is forced, and percolating ascends through openings I in the top
of the cylinder case in a filtered state, hence issuing by way of the spout or
orifice C Fig. 2 of the jug or apparatus.
With respect to domestic and other filtering arrangements generally, the water
or other liquid is made to descend and consequently must pass through the residue
of filtration, but a noticeable feature in my present invention is that the water
is made to ascend from bottom to top of the apparatus and to pass through the
filtering medium in such a manner, that the residue of filtration falls back into
the compartment T Fig. 2 provided for that purpose and situated at the inner
and lower end of the beforementioned filter cylinder. The water or other liquid
(as the case may be) entering the filtering medium above the aforesaid com-
partment passes upwards without disturbing the residue of previous filtration
which is kept from returning upwards by means of the lockneck arrangement f
Fig. 2 which leads into the lower compartment of the filter case. I prefer having
the apparatus (with the exception of the filtering medium) composed of metal.
But the body or central part may be composed of glass or other like material
while the remaining parts may be composed of brass or other suitable metal.
Having thus particularly described and ascertained the nature of this my inven-
tion and in what manner the same is to be performed, what I claim is :-
First. In an apparatus for supplying filtered liquids the improved means as

page_text: herein described for cleaning the filtering medium whereby the liquid is admitted
through apertures in the filter case as herein set forth.
Secondly. The improved construction of filtering arrangement by which the
liquid is conducted through the apertures referred to in the foregoing claiming
clause and is forced through the filtering medium in an ascending line and issues
through apertures in the cover of the filter case, substantially as and for the purposes
herein described.
Thirdly. The improved construction and arrangement of mechanism by which
a continuous supply of liquid can be obtained by an amount of exertion similar to
that required in pouring liquid from jug or other common vessel containing a non-
continuous supply, substantially as herein described.
Fourthly. In an apparatus for supplying filtered liquids, the improved con-
struction of valve mechanism for controlling the supply of liquid, the same com-
prising a watertight joint Figure 4, in the drawings, and so arranged that the
conical plug of the joint actuates a valve situated in the waterway or first passage
of the apparatus substantially as and for the purposes herein described.
Fifthly. The improved construction of valve mechanism whereby the same effects
the twofold purpose of a hinge upon which the apparatus works, and a valve for
turning off and on the water or other liquid.
Sixthly. The alternative means substantially as herein described for effecting a
similar object to that referred to in the preceding claiming clause, the same con-
sisting in the employment of a disc valve (or equivalent device) such valve having
ports in its discs opened and closed alternately by the tipping action of the
apparatus, and its spindle acting as a joint or hinge pin upon which the apparatus
operates.
