PROVISIONAL SPECIFICATION.
[Communicated from abroad by JAMES HENRY SOUTHCOTT and OWEN PHILIP PAYNE,
of Adelaide, in the Colony of South Australia.]
An Improved Combination Collapsable Bucket and Refrigerating and
Filtering Device.
I, THOMAS BOWLEY, of No. 537, Battersea Park Road, in the County of Surrey,
Watchmaker and Jeweller; do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to an improvement upon my former patent No. 9352, A.D. 1886.
It is found that it becomes necessary to rip the canvas surrounding the filter
of the above mentioned patent open, for the purpose of gaining access to the
filter whenever the latter requires cleansing or renewing.
1 therefore make the filter easily detachable by inserting a stiff ring in the diaphragm.
The filter is small enough to drop easily into the ring. It is also provided with a
ring adapted to rest upon the ring in the diaphragm, and a water-tight fit is secured
by the insertion between the rings of an elastic packing which is compressed by the
weight of the filter.
The latter is a box having two internal tubes springing up from the bottom. The
inner one is perforated, and the outer one plain, and not so high as the inner one.
The annulus in the bottom between the outer ring and the filter side is perforated.
The cover has a central pendent tube adapted to fit tightly within the perforated tube,
and is provided with a sponge.
The ordinary tap is replaced by a pipe which may be hooked to the top of the
bucket. A cover for the latter may be used.
COMPLETE SPECIFICATION.
An Improved Combination Collapsable Bucket and Refrigerating and
Filtering Device.
I, THOMAS BOWLEY, of No. 537, Battersea Park Road, in the County of Surrey,
Watchmaker and Jeweller, 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 improvements in the construction of the collapsable
combination buckets and refrigerating filters described in the specification of my
former Letters Patent, No. 9352, A.D. 1886.
It has been found that with a bucket having the filter fixed to the diaphragm in
the way illustrated in Fig. 3 of the drawings forming part of the specification of the
above mentioned Letters Patent, it is necessary to rip the bucket open in order to gain
access to the filter whenever the latter requires cleansing or renewing; and the object
of my present invention is to attach the filter to the diaphragm in such a way that it
can be easily detached and replaced without either cutting the fabric of either the
bucket or the diaphragm or ripping any of the seams.
In order that my invention and the means by which it is to be carried into practical
effect may be thoroughly understood, I will now proceed to describe them in detail,
referring in so doing to the accompanying drawings which are to be taken as part of
this specification and read therewith.
Fig. 1 is a perspective view, and

page_text: .
A is the bucket made as described in my former specification, and a is a rimless
cover of the same material as the bucket, adapted to be held in position by the pressure
upon its edge of the suspension cords a¹. It may be loose or loosely hinged to the
bucket-top. B is the diaphragm the centre of which is cut away to receive a strong
ring C, preferably of metal. The ring and diaphragm are firmly joined together in
any convenient way, e.g., by making the ring flanged, and whipping the diaphragm to
it as shewn in Fig. 2.
This
D is the filter having a flange d formed upon its top, by which it is adapted to
hang from the ring C. Suitable provision is made for securing a water-tight joint
between the filter-body and the ring by interposing a ring of elastic packing e.
is shewn as lying in a seat formed in the face of the ring, into which it will, for the
purpose of my invention, be squeezed by the diameter of the filter. Or, the seat may
be formed in the top of the ring, when the weight of the filter will keep the flange d
down water-tight upon the packing.
"
Two perforated rings of different diameters stand up from the filter-bottom to which
they are connected water-tight. The larger one stands about two-thirds the height
of the filter, and the smaller one f is as high as the filter-top.
The annulus in the filter-bottom between the side and ring is perforated, but as
much of the bottom-surface as is comprised within the ring is either not perforated,
or is stopped off. The filter-cover has a central pendant tube h¹ adapted to stop off
the tube 9 to within a certain distance of the bottom, and to receive the well-known
filter-sponge i. The tube g and central part of the filter-bottom being stopped off as
described and illustrated, the course of the water through the filter will be as indicated
by the arrows.
In the specification of my said former patent I have shewn the draw-off device as
consisting of a tap.
Now, according to my present invention, I attach a pipe j made preferably of the
same material as the bucket, to the bottom a² of the reservoir provided for the filtered
water.
It may be attached to the reservoir-side just above the bottom, but I prefer the
position illustrated in the figures. The top of the pipe is gathered in round a ring, in
which a stopper is fitted.
A suitable suspension device, shewn in the drawings as consisting of a hook and
eye k, k is provided, by means of which the mouth of the 'pipe can be hung to the
bucket-top. Provided that the pipe be kept hooked up to this level it is clear that the
filtered water cannot escape, even if the stopper be lost.
The superiority of the pipe to the tap device consists in this, that the reservoir can
be emptied by the pipe much more rapidly than by a tap-device and more thoroughly
than by a draw off device fitted to the side.
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:
1. The combination of diaphragm, ring attached watertight thereto, removable
filter adapted to hang from the said ring, and a packing adapted to be squeezed
between the two, as and for the purpose set forth.
2. The combination with the collapsible reservoir, of a flexible draw off pipe of a
length sufficient to be hung from the bucket-top above the level of the filtered water
in the reservoir as set forth.
3. The combination with a collapsible combination bucket and refrigerating and
filtering device, of a rimless cover adapted to be held upon the bucket-top by the
pressure upon its edge of the suspension cords as set forth."
Dated this 8th day of May 1889.
