PROVISIONAL SPECIFICATION.
Improvements in Filters.
FREDERICK ROGERS LIPSCOMBE, 45, Queen Victoria Street, London, Water
Filter Manufacturer, do hereby declare the nature of this invention to be as
follows:-
A filter according to my invention is constructed as follows-
I take a hollow vessel made of earthenware, metal, or other suitable material,
and divide it into three compartments; an upper, a centre, and a lower. The
upper and lower chambers are connected together by a number of tubes, open at
both ends, which are fastened into the plates forming the bottoms of top and
central chambers. All but one of these tubes are stopped with caps at their
upper ends, to prevent the passage downwards of any liquid poured into top
chamber through them. These capped tubes are perforated for an inch or so
immediately under the plate forming the bottom of top chamber. These tubes
are fitted with bottle brushes made of fibre, bristles or metal, or both interwoven,
attached to handles, accessible when the caps of tubes are removed; or I may
vary the fittings of tubes, to a worm of a screw, arranged so as to compel liquid
ascending, or descending, to do so in a circuitous mianner.
The action of my
filter is:
1. The pouring of the liquid to be purified, into the upper chamber.
2. The descent of liquid, by the tube open at both ends, into bottom chamber.
3. The ascent of liquid, through the bottle brushes, or worms of screw arrange-
ment, in the capped tubes, up to the perforations in these tubes immediately
under the top plate.
4. The descent of liquid into the central chamber, through the perforations.
5. The draw off of liquid by a convenient cock situate at bottom of central
chamber.
6. The draw off of sludge accumulated in bottom chamber by a convenient
cock.
I also provide an arrangement for making the tubes removable together with
the plates into which they are fixed.
I also provide an arrangement of battery to electrify the brushes fitted in tubes,
when desirable.

page_text: FREDERICK ROGERS LIPSCOMBE, 45, Queen Victoria Street, London, E.C., Water
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:-
An improved filter according to this my invention is constructed as follows.
I take a hollow vessel made of earthenware, or other suitable material, and
divide it into three compartments, an upper, a centre, and a lower. The upper
and lower chambers, I connect together by a number of tubes, open at both
ends, which are fastened into the plates forming the bottoms of top and central
chambers. All but one of these tubes I stop with caps at their upper end, to
prevent the passage downward through them, of any liquid, or steam, poured
into the top chamber. These capped tubes 1 perforate for an inch or so imme-
diately under the plate forming the bottom of top chamber. These tubes I fit
inside with a spiral brush, made of fibre, bristles, or metal, or of both inter-
woven, or of other suitable material, attached to handles, accessible when the
caps of tubes are removed, or I may vary the interior fittings of tubes, to a worm
of a screw or suitably formed battle plates or cones, so as to compel liquid, or
steam, ascending, or descending through them, to do so in a circuitous manner.
The action of my improved filter is.
1. The pouring of the liquid, or the admission of steam, to be purified into the
top chamber.
2. The descent of liquid, or steam, by the tube open at both ends, into the
bottom chamber.
3. The ascent of liquid, or steam, through the spiral brushes, or worm of
screw, or other suitable arrangement as described, fitted into the capped tubes
up to the perforations in these tubes situated immediately under the top plate.
4. The descent of liquid, or steam, into the central chamber through the per-
forations.
5. The draw off of the purified liquid, or steam, by a convenient cock, situated
preferably at the bottom of central chamber.
6. The draw off of the sludge, accumulated in bottom chamber, by a con-
venient cock.
I also may provide an arrangement for making the tubes removable, together
with the plates into which they are fixed.
I may also provide an arrangement of electric battery, to electrify the brushes
fitted into the tubes when desirable.
A reference to the drawings will shew the action of my filter, together with
some variations of the manner in which it may be used.
Fig. 1. A is the top chamber, and receptacle for the liquid, or steam, to be
purified. B the tube open at both ends, through which the liquid, or steam,
descends into the bottom chamber C, there to deposit any heavy matter in
suspension. D, D, are the tubes open at bottom, and capped at top ends, and
perforated immediately under the fixed top plate, and fitted inside, each with
its spiral brush, worm of screw, or other suitable arrangement, as described by
me. E is the body of filter, which may be filled with suitable filtering media,
into which the liquid, or steam, passes through the perforations in tubes D, D.
F is the draw off cock for purified liquid, or steam. G is the cleansing vent for
sludge accumulated in bottom chamber C.

page_text: Fig. 2 is constructed on precisely similar lines to Fig. 1, with the addition
of air tight pontoons H, H, to float it at the surface of a liquid to be treated,
when desirable.
Fig. 3 is also constructed as Fig. 1, with the prolongation of the tube B into
a funnel, into which is placed a concentric funnel, which may act as the top
chamber marked A in Fig. 1.
Fig. 4 is also constructed as Fig. 1, with the addition of cap H, to top cham-
ber, so that the filter may be worked under pressure.
Having now particularly described, and ascertained the nature of this my in-
vention, and the manner in which the same is to be performed, I declare that
what I claim is:-
First. The splitting up of the body of liquid, or steam, to be purified, into a
number of small streams, conveyed through hollow tubes, or frames, each tube,
or hollow frame, being provided with an interior fitting of a spiral brush, worm
of screw, or other suitable arrangement as described by me.
Secondly. The arrangement, and several combinations of parts, constituting
respectively the improved filter, as described under Figs. 1, 2, 3, 4, and shewn in
the drawings accompanying this specification.
Dated this 14th day of December 1899.
