Chester, for the Invention of "IMPROVEMENTS IN JUGS FOR FILTERING
AND COOLING LIQUIDS."
Sealed the 5th November 1872, and dated the 10th May 1872.
PROVISIONAL SPECIFICATION left by the said Howard Busby Fox.
at the Office of the Commissioners of Patents, with his Petition,
on the 10th May 1872.
•
I, HOWARD BUSBY Fox, of Oxton, in the County of Ohester, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
JUGS FOR FILTERING AND COOLING LIQUIs," to be as follows:-
My Invention for improvements in jugs for filtering and cooling
liquids consists, first, of an addition of a filtering medium to jugs
manufactured under Letters Patent granted to me, bearing date the
30th day of May 1871, and numbered 1435; secondly, of an addition
of a cooling medium to jugs manufactured under the same Patent; and
thirdly, in applying these filtering and cooling mediums to jugs of
ordinary manufacture.

page_text: The Invention enumerated (No. 1435/") consists of forming a jug
with the top partly covered over and has a nozzle or spout down the
side of the jug, which nozzle or spout opens into the said jug through
the side and close to the bottom thereof, allowing the bottom of the
contents to be poured off first. Now in adapting a filtering medium 5

as to fit inside the jug, and be hermetically sealed round the top by a
suitable packing ring, the filtered liquid in this case being poured from 25
the ordinary spout of the jug.
In the case of applying a cooling medium to jugs I use the inner case

being filled with ice and hermetically sealed the ice will last longer
than if the air had access to it, also the ice being distinct from the
liquid in the jug will not mix with it as it dissolves. These cooling
cases or pans can be made to fit any jug, but are especially applicable
to those manufactured under Letters Patent as before enumerated. A 35
cooling medium is also obtained by using the filtering case or pan first
described to contain the ice, which as it melts filters through the carbon
Llock and mixes with the water below.

my Invention may be manufactured of any suitable kind of carthen-
ware, glass, metal, gutta percha, wood, or other substance suitable for
the manufacture of jugs.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Howard Busby Fox in the Great Scal Patent Office
on the 7th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HOWARD
BUSBY Fox, of Oxton, in the County of Chester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of May, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Howard Busby Fox, Her special licence that
I, the said Howard Busby Fox, my executors, administrators, and
assigns, or such others as I, the said Howard Busby Fox, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
JUGS FOR FILTERING AND COOLING LIQUIDS," upon the condition (amongst
others) that I, the said Howard Busby Fox, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Howard Busby Fox, 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 :—
My Invention for improvements in jugs for filtering and cooling
liquids consists, first, of an addition of a filtering medium to jugs manu-

page_text: factured under Letters Patent granted to me, bearing date 30th May
,1871, and numbered 1435; secondly, of an addition of a cooling medium
to jugs manufactured under the same Patent; and thirdly, in applying
these filtering and cooling mediums to jugs of ordinary manufacture.
The Invention enumerated (No. 1485, A.D. 1871) consists of forming
a jug with the top partly covered over and has a nozzle or spout down
the side of the jug, which nozzle or spout opens into the said jug through
the side and close to the bottom thereof, allowing the bottom of the
contents to be poured off first. Now in adapting a filtering medium
to the jug I dispense with the half cover on the top of the jug, and in
lieu thereof I insert into the jug an inner case or pan which extends
half way or suitable distance down the jug. This case or pan fits on
the top of the jug and is made air-tight by means of an india-rubber
ring or other suitable packing. This case or pan is fitted with a partial
cover which extends across the top next to the spout of the jug. This
semi-cover is similar to that on the jugs in the Patent before enumerated
and virtually takes the place thereof. The rest of the case or pan may
be covered over with a hinged lid. Inside the case or pan and at the
bottom thereof there is an orifice connecting the case or pan to the
interior of the jug. In this orifice I insert or place a block of carbon or
animal charcoal, similar to those used in ordinary filters, or layers of
charcoal, flannel, felt, or other suitable filtering medium may be used.
To give air and allow the contents of the jug to be poured away I
mould or attach a small tube down the side of the case or pan opening
into the under part of the jug. This filtering case or pan can be made
suitable for application to ordinary jugs being in this case of such size
as to fit inside the jug and be hermetically sealed round the top by a
suitable packing ring, the filtered liquid in this case being poured from
the ordinary spout of the jug.
In the case of applying a cooling medium to jugs I use the inner &
case or pan, but in this instance I hermetically cover the top by means
of an india-rubber band or washer, and dispense with the orifice in the
bottom, also the carbon block or filtering medium. The case or pan
being filled with ice and hermetically sealed, the ice will last longer
than if the air has access to it, also the ice being distinct from the 3
liquid in the jug will not mix with it as it dissolves. These cooling
cases or pans can be made to fit any jug, but are especially applicable

page_text: to those manufactured under Letters Patent as before enumerated. A
cooling medium is also obtained by using the filtering case or pan first
described to contain the ice, which as it melts filters through the carbon
block and mixes with the water below.
Filtering or cooling jugs with their inner cases or pans according to
my Invention may be manufactured of any suitable kind of earthenware,
glass, metal, gutta percha, wood or other substance suitable for the
manufacture of jugs.
The before-going being the nature and object of my Invention, I will
now proceed to describe more in detail how the same may be carried out
into practical effect, and for that purpose I have hercunto attached a
Sheet of Drawings illustrative of my Invention as will enable the same
to be manufactured. Like letters and figures marked on the Drawings
are used to denote similar parts throughout the various views.
Figures 1 and 2 illustrate sectional elevations of filtering jugs con-

page_text: or pan is fitted to the jug with a packing ring in a similar manner to
the filtering case or pan before described. In Figure 7 the filtering case
or pan has a loose bottom N which is perforated. The bottom N screws
into the filtering case C, and may be filled with animal charcoal, flannel,
felt, sponge, or other suitable filtering medium, the screw O being used
for tightening down the perforated cover P, as will be well understood.
The water upon being poured into the case or pan perculates or filters
through the carbon block in manner similar to ordinary filters. The semi-
cover E prevents the water being spilled from the filtering can or case,
but at the same time allows the water to be poured from the jug.
Having now described and ascertained the nature, object, and pur-
poses of this my Invention, and how the same may be carried into
practical effect, I would have it understood that I do not confine
myself to the precise details as shown in the Drawings, as the same may
be considerably varied without departing from my Invention; but what I
claim as new and desire to secure by Letters Patent as aforesaid is,—
Firstly. The filtering pan or case C fitted with carbon block or
filtering medium adaptable for use in any kind of jugs as now manu-
factured, substantially in the manner and for the purposes herein-before
described and set forth.
Secondly. The cooling pan or case K hermetically closed adaptable
for use in any kind of jug as now manufactured, substantially in the
manner and for the purposes herein-before described and set forth.
In witness whereof, I, the said Howard Busby Fox, have here-
unto set my hand and seal, this Fifth day of November, in the
year of our Lord One thousand eight hundred and seventy-two.
HOWARD BUSBY (L.s.) FOX.
