improvements in Apparatus com
Water.
I, CECIL HENRY FITZMAURICE, of Southsea House, Threadneedle Street,
City of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus connected with softening
and purifying water.
According to this invention, the water to be treated flows into a small tank, and
is automatically flushed out when it has reached the necessary height.
When the tank is nearly full, a stop, or float rises, and when the water has
reached the proper height, the float raises a lever and opens a valve in another
tank containing the reagent, such as soda and lime in concentrated form, this joins
the rush of water from the supply tank previous to entering the precipitating tank
which is at a low level and in communication by pipes. This tank is of sufficient
capacity to allow time for precipitation, and then to flow up other pipes to a
receiver, or through a clarifying tank and then to the receiver previous to
withdrawal.
On the lowering of the water in the supply tank by the flush created, the float
is released from contact with the lever, and allows the valve in the reagent tank
to close, so that only sufficient reagent is released to treat the water.
The precipitating tank is divided by a partition into two parts, or two tanks
may be provided, in one of which, or in the receiver, is a grating near the top.
Pieces of cork, or floating substances coated with charcoal, "polarite," sand, or
other comparatively rough material by means of cement, or otherwise, float in the
water beneath the grating, and serve as a filtering medium which collects the
precipitated matter.
As the collected matter accumulates on the cork, the latter falls to the bottom
of the tank by gravity, where it may be stirred up and cleansed by an agitator
In
arranged for the purpose, the cork rising again in the water after cleansing.
lieu of cork, I may employ matting of cocoanut fibre, or other material.
Above the grating, pieces of pottery, felt, or the like, may be arranged for
further filtration of the water before its exit from the tank.
Improvements in Apparatus connected with Softening and Purifying
Water.
I, CECIL HENRY FITZMAURICE, of Southsea House, Threadneedle Street,
City of London, Engineer, 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 apparatus connected with softening
moton

page_text: According to this invention, the water to be treated flows into a small tank A,
as in the annexed drawing, and is automatically flushed out when it has reached the
necessary height, such as indicated by the dotted line a. The float C in rising
by its arm D raises a lever E and opens a valve F in another tank G containing
the reagent, such as soda and lime which then flows therefrom, this joins the rush
of water from the supply tank A in the box H previous to entering the precipitating
tank J on one side of a partition K and in communication by a pipe L with the
filtering vessel or receiver M.
The compartment of the tank J is of sufficient capacity to allow time for
precipitation, and then for the water to flow into a receiver. M and through a
clarifying medium N previous to withdrawal by the tap P...
On the lowering of the water in the supply tank A by the flush created in the
siphon Q, the float arm D is released from contact with the lever E, and allows
the valve F in the reagent tank to close. Only sufficient reagent is released to
treat the quantity of water from A at each flush.

The tank M, contains pieces of cork or floating substances coated with charcoal,
'polarite," sand, or other comparatively rough material by means of cement, or
otherwise, which may float in the water beneath the filtering medium N to collect
the flocculent matter.
As the flocculent matter accumulates on the cork, it becomes weighted and falls
to the bottom of the tank by gravity, where it may by a stirring be cleansed, the
cork then rising again in the water to collect a fresh quantity.
A matting of cocoanut fibre or other material will filter the outgoing liquid.
Between the gratings N₁, pieces of pottery, felt, or the like may be arranged
for further filtration of the water before its exit from the tank.
The lower part of the cistern R is provided with a ball tap at S, and this is
opened by the lowering of the ball T in the tank G by the escape of the agent
into H, so that the level of liquid in the agent tank G is nearly always
maintained.
The cistern R is supplied from time to time by the tap U being opened, said tap
being on a branch V of the main supply W also provided with a tap ✗ for
intermittent flow into tank A under the action of the ball Y arranged in the
precipitating tank J.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improvements in apparatus comprised of the several tanks A, G, J, M,
and a mixing box H so arranged that a determined quantity of water can be
softened and purified by a reagent then clarified by precipitation and filtration, as
and in the manner set forth and shown.
2. In connection with a water softening and purifying apparatus, the arrange-
ment of the automatic acting flush tank A with reagent tank G also operated
(automatically) from a single ball G and arm D, the contents or portions
thereof being simultaneously discharged for commingling or mixing in box H for
the purpose set forth.
