PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Softening and Purification
of Water.
We, ANDREW HOWATSON, and WILLIAM EDWARD LAWRENCE, both of 4 West-
minster Chambers, Victoria Street, Westminster, Middlesex, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a novel combination of apparatus, in 'or by which, hard
water can be softened and said water filtered.
The apparatus is specially designed for use in Dwelling Houses and consists
essentially of three vessels. First a receiver containing a box with tapered sides and
charged with soda crystals, or other water softening agent and with a passage through
it for a flow of water which becomes impregnated.
Below the box is a chamber by which water may flow from the water receiving
portion of the tank to commingle with the impregnated water which flow together
through a chamber provided with baffle plates. The water then passes down a pipe to
near the bottom of a second tank, up which the water rises slowly from the bulk
which the tank contains and within which tank a precipitation of solid or flocculent
matter takes place, if an agent be used which produces flocculent bodies.
The upper part of this second tank has a filter preferably of coker-nut fibre, by
which the water is clarified and it flows, after leaving the filter, into a third tank or
receiver, from which the supply for domestic purposes is taken.
This last tank has a ball floating in it in connection with the ball cock of the first
tank, so that the inflow of the service or supply to the first tank is regulated by the
level of the water in the third tank.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Softening and Purification
of Water.
We ANDREW HOWATSON, and WILLIAM EDWARD LAWRENCE both of 4 West-
minster Chambers, Victoria Street, Westminster, Middlesex, Engineers do hereby
declare the nature of our said 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 a novel combination of apparatus by which hard water
can be softened and said water filtered.
The apparatus is specially designed for use in Dwelling Houses and consists
essentially of three vessels A. B. O, as shown on the annexed drawings Figures 1.
and 2. First a receiver A containing a box D with tapered sides and charged with
soda crystals or other water softening agent, and with a passage E through it for a
flow of water which becomes impregnated. Below the box D is a chamber F by
which water may flow from the water receiving portion G of the tank A to commingle
with the impregnated water which flow together through a chamber provided with
baffle plates H, H, or in a zigzag manner. The water then passes down a pipe I to
near the bottom of the second tank B up which the water rises slowly from the bulk
which the tank contains and within which tank B a precipitation of solid or flocculent
matter takes place, if an agent be used which produces flocculent bodies.

page_text: The upper part of this second tank B has a filter J preferably of coker nut fibre
by which the water is clarified and it flows, after leaving the filter through an
outlet K into the third tank or receiver C from which the supply for domestic purposes
is taken.
This last tank C has a ball L floating in it in connection with the ball cock
or valve M of the inflowing pipe N, said ball cock being in the first tank A so
that the inflow of the service or supply to the first tank A is regulated by the
level of the water in a third tank C.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
The arrangement of the three tanks, the tank A having the soda crystals or other
agent container and also the baffle plates as hereinbefore described and shewn in the
drawings for the purpose set forth.
