page_text: We JAMFS ARMSTRONG, of 11 Grange Street Rusholme, Cabinet Maker, and
WILLIAM HEYWOOD, of 1 Clowes Street West Gorton, Publican, both of Manches-
ter, in the County of Lancaster, do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to manufacture a combined filter and cooler (for
water or other liquids) in earthenware of a form which shall be portable and also
easy of manufacture and economical in cost.
For the purposes of our invention we make an earthenware vessel in the form
of two cylinders, one within the other, with a closed bottom and open at the top,
the top of the inner cylinder being lower than that of the outer one, and having
an aunular space between the two. For convenience of manufacture we prefer to
make the walls of the cylinders slightly conical, that is, thicker towards the bottom
so that they will draw out of the moulds or dies. Each cylinder is fitted with a
removable lid or cover.
In the inner cylinder at a convenient distance from the top we form or fit au
inner ring or flange or other projections for supporting the perforated metal discs
between which is placed the filtering medium in the usual manner.
At the bottom of the annular space we have at one place or at two opposite places
a solid lump of earthenware joining the two cylinders and through this lump we
hore a hole communicating from the outside with the inner cylinder or filter in
which we fix (by means of a cork or otherwise) a tap by means of which the filtered
water or other liquid can be drawn off.
The annular space round the filter is filled with broken ice well pressed down
together and forms a refrigerator to keep the filtered water or other liquid always
cool.
If it is required to use the vessel for cooling milk, wine, or other liquid uot
required to be filtered, the filtering material may be removed, in which case the
capacity of the inner vessel will be somewhat increased.
The vessel is intended to be placed on a convenient stand of such a height above
a table or counter as to allow of a tumbler or other drinking vessel being placed
beneath the tap or taps.

page_text: We JAMES ARMSTRONG, of 11 Grange Street, Rusholme, Cabinet Maker, and
WILLIAM HEYWOOD, of 1 Clowes. Street West Gorton, Publican, both of Manches-
ter, in the County of Lancaster, 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 this invention is to manufacture a combined filter and cooler (for
water or other liquids) in earthenware of a form which shall be portable and also
easy of manufacture and economical in cost. And in order that our invention may
be clearly understood we have annexed hereto a sheet of drawings referred to in
the following description.
Fig. 1 is a vertical section through a filter and cooler made according to our
invention. Fig. 2 is a plan thereof, with the cover removed; and Fig. 3 is a
detached section taken at A-A on Fig. 1.
For the purposes of our invention we make an earthenware vessel see Figs. 1
and 2, in the form of two cylinders a, b one (b) within the other (a), with a closed
bottom c, and open at the top, the top of the inner cylinder 6 being lower than that
of the outer one a as seen on Fig. 1, and leaving an annular space d between the
two.
For convenience of manufacture we may make the walls of the cylinders slightly
conical, that is, thicker towards the bottom so that they will draw out of the
moulds or dies. Each cylinder is fitted with a removable lid or cover, or one cover
as seen at e Fig. 1 may serve for both cylinders.
In the inner cylinder at a convenient distance from the top we may form or fit
an inner ring or flange or other projections for supporting perforated metal discs
between which is placed the filtering medium in the usual manner.
Or we may provide a suitable receptacle f having a perforated bottom and fitting
in the inner cylinder b and made with a flange fi resting upon the upper edge of
the cylinder b to support the receptacle f in which the filtering medium is placed.
At the bottom of the annular space d we have at one place, or at two opposite
places as seen on Fig. 1, a solid lump of earthenware joining the two cylinders,
and through this lump we bore a hole g g see also Fig. 3, communicating from
the outside with the inner cylinder or filter b in which we fix (by means of a cork
or otherwise) a tap not shewn by means of which the filtered water or other liquid
can be drawn off, an air hole or passager being provided say down one side of the
receptacle (see Fig. 2) to allow the contents of the vessel b to be so withdrawn.
The annular space d round the filter is filled with broken ice well pressed down
together and forms a refrigerator to keep the filtered water or other liquid always
cool..
If it is required to use e vessel for cooling milk, wine, or other liquid not
required to be filtered, the filtering material and the discs or the receptacle f
may be removed, in which case the capacity of the inner vessel b will be somewhat
increased.
The vessel is intended to be placed on a convenient stand of such a height above
a table or counter as to allow of a tumbler or other drinking vessel being placed
beneath the tap or taps.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is:-
A vessel in the form of two concentric chambers having a space outside the

page_text: inner chamber for ice, and so made and fitted that it can be used for filtering and
for cooling substantially as hereinbefore described and illustrated by the annexed
drawings.
