Improvements in Filter Water Bottles.
I PERCY HADDAN of the firm of Herbert & Co., Patent Agents of 18 Buckingham
Street, Strand W.C. in the County of Middlesex, Civil Engineer do hereby declare the
nature of this invention, a communication from abroad by Patrick Lewis of the City
of Quebec in the Province of Quebec, Canada, Inventor to be as follows:-
The object of this invention is a filtering water bottle principally for field use, that
is to say a bottle or flask into which water may be poured and which shall filter and
store said water in a filtered and pure condition ready for use.
A mouth is
To this end a bottle or case is made being divided into two chambers.
provided through which water may be poured into one of the chambers whence it
passes through a filter into the other chamber where it is stored until required to be
drawn off for which purpose a mouth is provided to the latter chamber.
.
The bottle may be made of tin, vulcanized rubber, glass, enamelled ware or any
other suitable material and of a convenient shape preferably flat and circular.
The invention may be carried out in the following manner. Across the bottle is a
partition dividing the bottle into an upper and lower compartment. In said partition
is an opening fitted with a collar into which a movable filter may be adjusted in such
a manner as to render the opening watertight so that the water cannot pass from one
compartment into the other except through the filter. The filter is a movable cylinder
packed with filtering material having the lower end capped with finely perforated tin
or other material and the upper end fitted with a similar perforated but movable
stopper..
To the cylinder is attached a long loop handle extending upward to the mouth of
the bottle when the filter is in place so that the filter may be removed or inserted by
means of said handle, it being passed into the bottle through the mouth.
The perforated stopper beforementioned is made to slide upon the loop handlō for
The inlet and outlet mouths are

respectively closed by screw stoppers and the loop handle is of such length as to come
in contact with the stopper of the inlet mouth when screwed down so that the filter is
securely fixed in position.
A tube of tin or other material may be screwed in the partition and extend upward
to the upper part of the upper chamber so that as the filtered water enters the lower
chamber the foul air if any therein escapes into the upper chamber through said
pipe.

I PERCY HADDAN of the firm of Herbert & Co. Patent Agents of 18 Buckingham
Street Strand W.C. London in the County of Middlesex, Civil Engineer do hereby
declare the nature of this invention, a communication to me from abroad by Patrick
Lewis of the City of Quebec in the Province of Ontario, Canada, Inventor 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 a filtering water bottle principally for field use that is
to say a bottle or flask into which water may be poured and which shall filter and
store said water in a filtered and pure condition ready for use.

page_text: In the accompanying drawing,
Fig. 1. is a sectional elevation of a water bottle constructed of tin, vulcanized rubber,
glass, enamel agate ware or other material embodying this invention.
Fig. 2 is a transverse sectional view of the same.
Fig. 3 is an outside view of the same.
Fig. 4 is a sectional elevation showing the filter D represented in Fig. 1.
A is the mouth of the bottle having screw stopper B through which water is supplied
to the water chamber C from whence it passes through the movable filter D into the
compartment E in a filtered and pure condition from whence it may be drawn off at
will through the mouth or opening F in the bottle which is also supplied with a screw
stopper.
G is a partition which divides the compartment C from the compartment E
having an opening in the centre fitted with a collar H into which the movable
filter D is adjusted in such a manner as to render the opening water tight, except
through the filter but so that the filter may be removed at will.
D is the filter being a movable cylinder packed with filtering material and set
into the water tight collar H having its end capped with finely perforated tin or
other material and the upper end fitted with a finely perforated stopper of the
same material which stopper is grooved at the sides to permit of its being drawn
up and down on the loop handle K which latter is permanently secured to the
filter D for the purpose of enabling the same to be withdrawn through the mouth
of the bottle A for cleaning and having the filtering material renewed. The loop
handle K is adjusted so as to come in contact with the stopper B when screwed
down, by which means the filter D is kept securely fixed in the collar H.
I is a tube of tin or other material secured to the partition G and opening
into the compartment E by means of which, as the filtered water enters the
compartment E, the foul air, if any escapes into the upper compartment through
the opening J in the tube I at the top of the said compartment C.
I make no claim to the shape of the bottle, nor to the material of which it is
made nor to the screw stoppers employed for I am aware that these are not new
but,
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The combination of the water chamber C with the filtering compartment D
substantially as and for the purpose hereinbefore set forth.
2. The combination of the filtering compartment D set in the collar H of the
partition G substantially as and for the purpose hereinbefore set forth.
3. The combination of the filtering compartiment D with the filtered water
chamber E substantially as and for the purpose hereinbefore set forth.
4. The combination of the filter D with the loop handle K and the stopper B
substantially as and for the purpose herein before set forth.
5. The combination of the tube I opening into the compartment E through the
partition G into the compartment C substantially as and for the purpose herein-
before set forth.
6. The combination of the filtered water chamber E with the lower mouth or
opening F substantially as and for the purpose hereinbefore set forth..
