COMPLETE SPECIFICATION.
An Improved Water Filter.
We, JAMES HENRY SOUTHCOTT, ОWEN PHILLIP PAYNE, both of Currie
Street Adelaide, in the Province of South Australia, Mechanics, and JAMES
CLARKSON SUNTER, of Harrow Road, St. Peters, also in the said province,
Salesman, 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 apparatus for obtaining the filtration or purification of
water, commonly termed water filters. It is designed more particularly for use in
combination with water bags, in which application it is for convenience more
particularly herein described, but may be applied to all classes of water filters.
The object of its construction is to provide a cheap inexpensive and effective
filter, which can--first, be itself easily taken to pieces for cleansing purposes, and
secondly, be readily removable from the water bag for the purpose of cleansing.
the bag.
We accomplish these purposes by the construction hereinafter described, and in
order that it may be well understood will proceed with the same by the aid of the
accompanying drawings, in which :-
Fig. 1. is a longitudinal sectional elevation of our improved water filter
complete.
Fig. II. a side view of the same.
Fig. III. a plan of the casing with cover removed.
Fig. 1V. a top view of the filter in position.
Like letters of reference indicate corresponding parts in the several views.
It will be seen that our improved filter consists of a hollow casing A which may
be constructed of metal or any other suitable material and of any shape or size,
but preferably circular. This casing is provided with internal partitions B B¹ also
of metal (but the inner one of which is perforated for the purpose hereinafter
mentioned), so as to form chambers C and D, which are filled with charcoal or any
other suitable filtering material, and has a portion of its base as at B also.
perforated to allow of the exit of the water from the outer chamber C into the bag-
or receptacle beneath. It is further provided with a movable cover E, having a
projecting flange or rim F, and a circular partition or central tube Ġ of such
diameter and shape as will closely fit into the inner or perforated partition B' of
the casing, the upper portion or opening of which is filled with a sponge. Into the
base of the casing and in the central tube G is soldered or otherwise fixed one end
of a short bar H, the other end of which is bent, to form a hook as at H', and to.
pass over the edge of the cover and tube G containing the sponge, by which
arrangement the filter or casing is held to the cover when in use.
The filter or casing complete is passed into position from above through an
opening made for the purpose in a partition J of the canvas water bag, and is
firmly held by the flange of the cover E, by which construction it may both be
quickly disengaged from the bag and readily taken to pieces for the cleansing
operation.
The direction of the water through the filter from the upper to the lower
chamber is shewn by the arrows. The water entering the filter casing through
the opening or tube G which is filled with sponge passes through the perforations
in the internal partition or tube B' near the bottom of the chamber D and rises.

page_text: through the charcoal or other filtering medium contained in this chamber until it
overflows over the partition B into the chamber C, whence after passing through
the charcoal or other filtering medium contained therein, it escapes through the
perforated openings B into the chamber or receptacle below.
To remove the filter for the purposes of cleansing, it is only necessary to press
the casing A upwards from its base when the flange F of the cover quickly
becomes freed from the partition J of the bag and allows the filter to be lifted out
bodily. The lower chamber of the bag or other receptacle can then be easily
cleansed through the opening in the partition J in which the filter was formerly
suspended. On the sponge being removed from the opening or tube G the
hooked end H' of the bar H can be pressed free of the cover into the central
.tube G, the cover lifted from the casing by the flange F, and the filter thus taken
to pieces for cleansing or renewal of the charcoal or other filtering medium
employed, when after being put together the filter can be readily replaced for use
as before.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First. In removable filters, the combination with a casing (such as A), of a
removable cover (such as E) provided with a flauged rim (such as F) and tube
(such as G), substantially as herein described.
Secondly. In removable filters, the combination with a casing (such as A)
having a tube (such as B¹) of a removable cover (such as E) provided with a
flanged rim (such as F), substantially as herein described.
Thirdly. In water filters, the combination with a casing (such as A) having a
tube (such as B') for a removable cover, of a bar or hook (such as H), substan-
tially as herein described and for the purpose indicated.
Fourthly. The herein described water filter, consisting essentially of a casing
(such as A) internal partitions (such as B B¹) removable cover (such as E) having
a flanged rim (such as F), and an opening or tube (such as G), a bar or hook (such
as H), all as a combination of parts, substantially as herein described and explained
and illustrated in the accompanying drawings.
Dated this 1st day of May 1896.
