PROVISIONAL SPECIFICATION.
Improvements in or relating to Filters.
I, WILLIAM EDWARD CADDELL, of 70, Mark Lane, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to the cooling of the water while it is being filtered and
may be conveniently carried into effect in the following manner :-
As applied to an apparatus to be placed upon the counter of a restaurant or
similar place I may provide the outer cylinder or casing carried upon a suitable
foot or stand and adapted to receive the cooling medium such as ice or a refrigerating
mixture, or the cooling may be effected by the expansion of gas. This cylinder
may have a tap for drawing off the waste the tap discharging over a funnel or
equivalent provided with a waste pipe.
The filtering medium preferably a Kieselguhr cylinder or block may be contained
within a smaller and concentric cylinder arranged within the outer casing; the water
may be conveyed from below the counter through the stand and into this casing
when it would percolate through the filtering body from the interior of which it
may be drawn off by means of a suitable pipe preferably provided with a stop tap
or equivalent, the discharge nozzle being with advantage situated vertically above
the previously described waste funnel.
A similar arrangement may be adopted for other applications of this invention,
the necessary modifications being made according to circumstances.

COMPLETE SPECIFICATION.
Improvements in or relating to Filters.
I, WILLIAM EDWARD CADDELL of 70 Mark Lane, in the City of London,
Merchant, 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 to the cooling of the water while it is being filtered and
may be conveniently carried into effect in the following manner :-
As applied to an apparatus to be placed upon the counter of a restaurant or
similar place I may provide the outer cylinder or casing carried upon a suitable
foot or stand and adapted to receive the cooling medium such as ice or a refrigerating
mixture, or the cooling may be effected by the expansion of gas. This cylinder
may have a tap for drawing off the waste the tap discharging over a funnel or
equivalent provided with a waste pipe.
The filtering medium preferably a Kieselguhr cylinder or block may be contained
within a smaller and concentric cylinder arranged within the outer casing; the
water may be conveyed from below the counter through the stand and into this
casing when it would percolate through the filtering body from the interior of
which it may be drawn off by means of a suitable pipe preferably provided with a
stop tap or equivalent, the discharge nozzle being with advantage situated vertically
above the previously described waste funnel.
A similar arrangement may be adopted for other applications of this invention,
the necessary modifications being made according to circumstances.

page_text: The accompanying drawing is a vertical section through a filter constructed
according to my invention.
A is the outer cylinder or casing carried upon a suitable foot or stand A¹ and
adapted to receive the cooling medium such as ice or a refrigerating mixture, or the
cooling may be effected by the expansion of gas. A is the tap for drawing off the
waste from A, and B is the funnel bowl or equivalent over which A' is located and
which may be provided with a waste pipe B₁ passing through the counter top C to
which the stand A' and funnel B may both be secured.
D is the filtering medium, preferably a Kieselguhr cylinder or block (but which
may be of other suitable material or shape) and which may be contained within the
smaller cylinder E arranged concentrically within the cylinder or casing A.
F is the water supply pipe which may pass through the counter top C and stand A¹
and be tightly secured to the lower end of the inner cylinder E to convey water
thereto...
At its upper end the inner cylinder E is tightly closed by a cover E' to which are
tightly connected the tube D' leading from the filtering medium D and delivery
pipe D which forms a continuation of D¹ and passes loosely through the cover A³
which is fitted loosely to the upper end of A.
The delivery pipe D' is preferably fitted with a cock or valve D³ for regulating
or controlling the delivery of the cooled and filtered water and it or another pipe
connected with D' is advantageously bent over as shown so that its delivery outlet
or end may be directly above the funnel B.
The cover A³ may be raised off the upper end of A when ice or equivalent is to
be placed in A around E.
The outer cylinder A. is preferably provided with a floor A.
It will be understood that when the water is to be cooled by the expansion of
gas the outer cylinder A will be gas tight and need not be provided with a
tap A*.
The before, described apparatus, may be modified without departing from the
spirit of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. A combined filtering and cooling device substantially as described.
2. The combination with a casing containing a filtering medium of another
casing surrounding it containing a cooling medium substantially as described.
3. The combination with a casing such as E containing a filtering medium and
having an inlet F and outlet D2 of a casing such as A surrounding it and adapted
to contain a cooling medium substantially as described and illustrated in the accom-
panying drawing.
4. The combination and arrangement of parts constituting the complete combined
filtering and cooling apparatus substantially as described and illustrated in the
accompanying drawings.
