FREDERICK ROGERS LIPSCOMBE 45 Queen Victoria Street London E.C.
Water Filter Manufacturer, do hereby declare the nature of this invention to be
as follows:-
1. A filter made according to my invention consists of a perforated cylinder or
series of cylinders or other suitable shape vessel-covered or not with filtering
cloth—with a water tight vessel attached for the purpose of keeping the whole at
or near surface of liquid to be treated.
2. Or I use a perforated tray to which water tight vessel is attached-and upon
such tray fix my filter or filters.
3. Or I use the cylinder or series of cylinders or other shape vessel with floating
arrangement attached-and filled with the matter from which a decoction is desired―
and placed in vessel containing diluting liquid-or diluting liquid may be passed
into it from interior.
With reference to case No. 1. The water to be purified passes through outside
of cylinders or other shaped vessel into an interior receptacle from whence it can be
drawn or pumped.
In case No. 2.
The water first passes through perforations in floating tray and
then through outside of cylinders or other shaped vessel into interior receptacle
from whence it is drawn or pumped.
In case No. 3. The cylinder or other shaped vessel is filled with the matter
from which a decoction is to be made & the diluting liquid poured into it-(the
floating arrangement being provided with a tube through it for that purpose)-and
then when receptacle of the decoction is sufficiently filled the floating filter is allowed
to rest upon surface of liquid-so extracting all the remaining strength in matter
from which decoction is desired to be made.

A Floating Filter to Purify and Clarify Water and other Liquids,
and to Assist in the Decoction of Animal, Vegetable, and Mineral
Matter when Mixed with Liquids.
FREDK. 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 :—
A filter made according to my invention consists of a perforated cylinder or
series of cylinders one within the other with space between-or other suitably
shaped vessel-covered or not with filtering cloth and with suitable filtering media
within attached at the upper end to a water tight vessel for the purpose of keeping
the whole at or near the surface of liquid to be treated-while the lower end of
vessel has a flexible tube attached to the delivery pipe for the purpose of allowing
the filter to rise & fall on liquid on which it floats.
Or I use a perforated cylinder or series of such cylinders or other suitably
shaped vessel with floating arrangement attached and filled with the matter from

page_text: which a decoction is desired—and which may be placed in vessel containing diluting
liquid, or the diluting liquid may be poured through the filter before placing it
for further decoction from matter in the vessel named above.
upon
Or I use a perforated tray to which water tight vessel is attached and such
tray construct my filter or filters.
A reference to the drawings attached will explain-where
Fig 1. A. is the air tight vessel B. outer perforated cylinder D the inner per-
forated cylinder C space between filled with filtering media. E air tube F draw off
pipe for purified liquid-and which is attached to flexible tube delivering into draw
off pipe the flexible tube having for object the rise & fall of filter with liquid in
containing vessel-be it tank pond or reservoir of any description.
Fig. 2. A perforated tray on which a number of filters may be constructed B air
tight vessel attached to the perforated tray to float it. CCC the filters DDD draw
off pipes E E E the flexible tubes all delivering into one large pipe F. Or they
might deliver into several smaller ones or into other tanks or reservoirs.
Fig. 3. A air tight floating vessel B perforated cylinder attached to A. filled
with matter from which decoction is to be made D funnel through which diluting
liquid may be poured.
Fig. 4. E vessel into which the floating filter may be dropped after diluting
liquid has been poured through funnel D.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed what I claim is.
That a floating filter made according to my invention as shewed in Fig. I can
be used in any resevoir pond or tank into which liquid impregnated with matter
in suspension is admitted without the liability of filter soon being choked up
by such matter as would be the case with any filter fixed at the bottom of
resevoir.
Secondly. My floating filter obviates the necessity of a secondary settling tank
in which it is usual to fix filters in order to protect them from the matter in
suspension received into the first tank or resevoir.
Thirdly. My floating filter taking only the best of the liquid from the surface
the chemical action of the filtering media is not interfered with by the matter in
suspension which has plenty of space to subside to the bottom of tank, and thus
greater efficiency of purification as well as durability is obtained.
Fourthly. In the floating filter constructed according to drawings Figs. 3 & 4
I claim that a decoction made by means of such apparatus ensures no waste of the
material and also the utmost is extracted from the matter used as the diluting
liquid has access to both inside & outside-and the mass being allowed to float
in the diluting liquid ensures the abstraction of all the diluting liquid can dissolve
or take up.
