I JOHN HENRY JACOBS trading as J. H. Graham and Co 69 Great Eastern
Street, Middlesex, Filter Manufacturer, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN FILTERS," to be as follows:-
In the usual method of constructing filters a partition is cemented within an
outer vessel to form a lower receptacle for containing the filtered water the upper
chamber above the partition having the filtering medium resting thereon but
communicating with the lower chamber by a tube.
This known method of construction prevents the lower chamber being examined
for cleansing or other purpose.
Now according to my invention I dispense with the partition as a fixed article
and in lieu therefore I construct or make a pan preferably of enamelled iron, to
drop into the outer vessel and rest upon an upper flange.
This enamelled pan contains the filtering block or medium and the tube which
goes into the outer case projects beyond the bottom of the pan and has a tap so
that should the pan be lifted, it can be used without the vessel, said pan can be
provided with handles, rings, or apertures to enable it to be suspended, or it may
be fitted on a tripod or other shape of stand.
A
The carbon block may be set at a distance above the bottom of the pan and a
perforated porcelain ring or disc be fitted therein, to increase the area of the block
exposed to the water.

I JOHN HENRY JACOBS trading as J. H. Graham and Co, 69 Great Eastern
Street, Middlesex Filter Manufacturer, 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:-
:-
In the usual method of constructing filters a partition is cemented and fixed
within a vessel to divide it into an upper and a lower compartment, the upper
chamber above the partition has the filtering medium or block fitted in and resting
on said partition the block being in communication with the lower chamber for
the filtered water by a tube.
This known method of construction prevents the lower chamber being examined
for cleansing or other purpose.
a
Now according to my invention which is represented in the annexed drawings
I dispense with the partition as a fixed article and in lieu thereof I employ
pan A preferably of enamelled iron with a flange or lip B at the top edge so that
the pan may be dropped into the outer vessel C and the lip rests upon the upper
part of said outer vessel as shown at Figure 1.
This enamelled pan contains the filtering block or medium D and the tube E
fitting into the block D projects beyond the bottom of the pan A. and has a tap F
so that should the pan A be lifted, it can be used without the vessel C said pan
can be provided with a handle or rings or apertures G may be arranged to the
pan A to enable it to be suspended or it may be set on a tripod or other shape of
stand as at Figure 2.
H is the tap for drawing off the filtered water.
The carbon block may be set at a distance above the bottom of the pan and a
perforated porcelain ring or disc I be fitted between as at Figure 2 to increase the
area of the block exposed to the water.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The improvements in filters herein before described in which the novel and
essential feature is, dispensing with the usual fixed partition and fitting a removable
pan containing the filtering medium in same as represented in the annexed drawings
for the purpose set forth.
