FREDK. ROGERS LIPSCOMBE 233 Strand London, Water Filter Manufacturer I do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improved apparatus for precipitating by means of
reagents in a wet or dry condition as may be found convenient the inorganic and organic
matter held in solution or suspension in liquids- & for purifying & clarifying the
liquid afterwards-the invention is comprised-
1st. In an apparatus for mixing automatically or otherwise the liquid to be treated
with the reagent employed for precipitating-and in which apparatus may also be an
arrangement for automatically opening a valve for the admission of reagent―—when used
in a state of solution-to liquid to be treated-or there may be an automatic
arrangement for turning a screw of a suitable shape-which may have a regulator
attached to it-to admit reagent when used in a dry state.
2nd. In an apparatus for mixing automatically or otherwise the crude reagent with
water or other solvent to bring it to a suitable strength for mixing with liquid to be
treated.
3rd. In an improved filter for purifying & clarifying the turbid liquid as it is
delivered from the mixing vessel or settling tank- -or the filter may be used for other
purposes.
"
At
4th. In an apparatus for treating the precipitate.
The vessel in which the automatic mixing of liquid & reagent takes place-which I
prefer to be cylindrical-is provided with a pipe made to the shape of inside of bottom of
vessel & this pipe is connected with that delivering liquid to be treated.
convenient intervals in pipe lying round bottom of vessel are pierced holes from which
liquid can impinge upon a revolving water wheel pivoted upon the top of a central
waste pipe-& so causes it to revolve-The reagent may be admitted by a separate
pipe-the revolution of the water wheel will mix reagent & liquid to be treated."

page_text: The apparatus for mixing crude reagent with water or other solvent consists of a
vessel in which reagent in solution is placed & kept stirred by steam or other power.
Connected with above by means of a pipe is another vessel supplied independently by a
solvent of reagent used-The concentrated solution of reagent being admitted to the
second vessel & regulated supplies of solvent meeting it-the reagent can automatically
be kept at a suitable & given strength.
-
The filter consists of a perforated cage within which is a smaller perforated cage
covering hole of delivery pipe-both or either of these cages may be covered with a
suitable filtering cloth & the intermediate space may be filled with approved
filtering media The apparatus for treating the precipitate consists of an endless band
of perforated metal stretched upon rollers at suitable distances & which rollers are
caused to revolve by steam or other power so that precipitate being delivered upon
the perforated metal at one end-parts with its liquid through perforations & is so
carried on to other end where it may be received between rollers & pressed dry-
the perforated metal as it passes to underside of rollers may go through a tank
supplied with water or other cleansing liquid.

FREDERICK ROGERS LIPSCOMBE Water Filter Manufacturer 45 Queen Victoria
Street (formerly of 233 Strand), London do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described.
and ascertained in and by the following statement:-
My invention relates to an improved apparatus for precipitating by means of reagents
in solution or in a dry condition as may be found convenient the inorganic and
organic matter held in solution or suspension in liquids and for purifying and clarifying
the liquid afterwards, and for treating the precipitate.
The invention is comprised-
First-In an apparatus for mixing automatically or otherwise the liquid to be treated
with the reagent employed for precipitating-in which apparatus may also be an
arrangement for automatically opening a valve for the admission of reagent when it
is used in solution.
A reference to the drawing Fig. 1 will explain my apparatus-A is the pipe
admitting liquid to be treated-which issuing from arms a. a. or it may be made to
issue from holes in pipe a² laid round bottom of vessel-impinges upon a revolving
water wheel C-which may be provided with arms D D D fixed to it for the purpose
of mixing together the liquid to be treated and reagent admitted from a separate
vessel M. M. is the automatic valve-which is raised to admit reagent upon the
liquid to be treated forcing its way up pipe A to arms a. a. and holes in a³.
When the reagent is used dry-my apparatus consists of a vessel-cylindrical
preferably to which liquid to be treated is admitted by a pipe and similar arrange-
ment to that described above-and made to impinge upon a revolving water wheel'
fixed to a rod passing through its centre-this rod is pointed at its lower end and
takes a bearing on a convenient spot-preferably in the centre of vessel-the upper
end of rod is screwed-for the purpose of drawing down reagent-as it revolves-
from receptacle above-the screw may have a regulator for delivering reagent
attached to it-The regulator I prefer is a spiral of thin metal following the worm of
screw and choking the hole at bottom of receptacle containing reagent-when required
-fixed to the upper end of spiral or upon the screw may be a disc preferably oval in
form-which in revolving with screw comes in contact with weighted governors
pivoted from above. The action of the governor regulates the speed of the disc
fastened to screw and thus the delivery of dry reagent-from hopper is also regulated.
Connected with rod and with outer rim of water wheel is an inverted funnel over
which reagent is distributed by the action of the revolving screw above-and thence

containing dry reagent-B rod-pointed at lower end and screwed at top-C revolving
water wheel attached to rod-and inverted funnel D. E pipe introducing liquid to
be treated. F pipe conducting liquid and reagent in a mixed state to other
vessels the pipe F may be situated at sides of vessel if found more convenient-
G eccentric disc attached to screw and which moves the weighted governors H. H.
Second In an apparatus for mixing automatically or otherwise the crude reagent
―or its concentrated solution with water or other solvent to bring it to a suitable
strength for mixing with liquid to be treated-A reference to Fig. 3 will explain
my apparatus A a cylindrical or other shaped vessel-B pipe admitting solvent for
reagent in regulated quantities by way of C or other like arrangement inside
vessel D pipe admitting crude reagent or its concentrated solution in regulated
quantities from vessel E. F pipe admitting the mixture of reagent at required
strength to vessel H. Whence it may be conducted by way of valve K to
arms L L and mixing vessel below.
Third In an improved filter and settling tank for purifying and clarifying the
turbid liquid as it is delivered from the mixing vessel.
My improved filter consists of a perforated cage made of galvanized iron-
copper or other suitable material--within which may be a smaller perforated
cage-both or either of these cages may be covered with a filtering cloth-and the
intermediate space may be filled with approved filtering media-The cage or cages as
described may be fitted to a delivery pipe-fitted to tank in which they are placed
-A reference to Fig. 4 will explain-A is the delivery pipe for purified liquid-
after its passage through cages-B. B. B the perforated outer cages-0 CC the
perforated inner cages-My improved settling tank is made by the particular arrangement
of partitions and perforated or corrugated plates in such tank. The plates forming parti-
tions reach alternately from within a short distance of top of tank to quite the bottom-
and from a short distance from bottom of tank to quite the top so as to cause liquid
admitted at one end of such tank to perform a prolonged course to outlet at other
end on every alternate partition-preferably at the bottom I fix a narrow shelf
upon which may be rested perforated or corrugated plates which lean at the top
against the next partition and so offer an additional impediment to the passage of
liquid and afford a lodging place for the particles of precipitate as liquid passes
through-and may cover the perforated plates with filtering cloth or may use
the perforated or corrugated plates without the ledges described and rest them upon
the bottom of tank-A reference to Fig. 5 will explain my improved settling tank-
A inlet for liquid-B B B partitions in tank-C. C. C. ledges or shelves on alternate
partitions. D D D perforated or corrugated plates-E outlet-F. air tight cover if
required.
Fourth In an improved apparatus for treating the precipitate-My apparatus
consists of an endless band of perforated metal or other suitable material-stretched
upon and working over rollers placed at suitable distances apart and which rollers
are caused to revolve by steam or other power-so that precipitate being delivered
either alone or with any other substance upon the perforated material at one end-
parts with most of its liquid through the perforations in transit to the other end-
where it may be received between rollers and pressed dry-the perforated material as
it passes to the underside of rollers may go through a tank supplied with water or
other cleansing agent-A reference to Fig. 6 will explain my improved apparatus-
A pipe delivering precipitate-B B B rollers worked by steam or other power C. C.
endless band of perforated material-D tank containing cleansing agent for endless
band E tray to catch liquid percolating through C. C. A reference to Fig. 7 will
explain a combination of parts forming a complete apparatus for precipitating
the organic and inorganic impurities in liquids and for clarifying it afterwards where
A is tank containing crude reagent-B mixing tank for crude reagent and its solvent
-C. receiving tank for reagent at proper strength for mixing with liquid to be
treated D receiving tank for turbid mixture of liquid treated and reagent E settling
tank F filters fixed in tank.

page_text: 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
First In the precipitating apparatus the means employed for automatically
supplying regulating and mixing the precipitating reagent in proper proportions
with the liquid to be treated-as it flows or is forced into the vessels or tanks as
herein described in reference to the drawings.
Second-In the construction of the filter and of the settling tank as herein described
in reference to the drawings.
Third The combination of the various parts forming my improved apparatus for
precipitating purifying and clarifying and for treating the precipitate as herein
described and shewn in the annexed drawings.
