PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Purification and Softening
of Water.
We, ANDREW JAMES BELL and PETER ADAM GARDNER BELL, both of 41, Cor-
poration Street, Manchester, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:
This invention relates to improved apparatus for the purification and softening
of water by which all classes of water delivered under pressure either by pumping
or other forces may be treated chemically.
In this invention we construct duplicate tanks in which we place chemical
solutions which are or may be suitable for purifying and softening the water that
is required to be treated. The aforesaid chemicals are thoroughly mixed by
paddles or agitators that are fitted in either or both tanks, and actuated by suit-
able gearing.
An arrangement of pipes conveys the chemical solution from said tanks to a
smaller tank in which an agitator is also fitted, the supply from the larger tanks
being regulated by a ball tap or an equivalent. A connection is formed between
the herein last named tank and a small pump or measuring cylinder whose size
is regulated in proportion to the size of a force pump that is placed preferably
in a line therewith for pumping the water that is to be purified and softened,
and worked by any ordinary power, the aforesaid measuring cylinder and force
pump being so connected as to work always in ratio. The water supply pipe to
the force pump is placed in a position convenient for connecting a pipe thereto
from the aforesaid measuring cylinder, and a connection is formed between the
force pump and a pressure settling tank which may be constructed of any pre-
ferred shape, and the bottom of said tank may be dished. Suitable scrapers
arranged so that they can be revolved by gearing, are placed within the tank and
blow out cocks are fitted in or near the bottom of the tank for the removal of
dirt or sediment at intervals. A series of mechanical filters such as are described
in the Specification of the Patents Nos. 2384 of 1897 and 23178 of 1897 or other
class of suitable filters are placed contiguous to and in connection with the afore-
said pressure settling tank outlet pipes are fitted to said mechanical filters and
provided with an arrangement of valves by which water from the filters may be
forced through a bye pass to which a box or cylinder is attached for the reception
of suitable chemicals for neutralizing purposes.
In the application of our invention the chemical solution that is intended to
be used for purifying and softening the water to be treated is drawn into the
small pump or measuring cylinder hereinbefore named by its piston or buckets
which is worked in ratio with the force pump, and on the return stroke the solu-
tion that has been thus drawn into the cylinder is forced into the supply pipe
at the period when the water is being drawn in by the pump. The chemical
solution and the water being thus mixed in the proper proportions are then forced
into the settling tank, passing upward through the said tank and through a

page_text: collecting dome at the top of said tank and thence through a series of mechanical
filters as herein before named; the water from these is collected by cone strainers
and forced through a bye pass when a supply of neutralizing mixture regulated
by suitable valves is mixed with the water from the aforesaid filters.

Improvements in Apparatus for the Purification and Softening
of Water.
We, ANDREW. JAMES BELL and PETER ADAM GARDNER BELL, both of 41, Cor-
poration Street, Manchester, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
This invention relates to improved apparatus for the purification and softening
of water by which all classes of water delivered under pressure may be treated
chemically.
In the accompanying drawing Fig. 1 is a side elevation, Fig. 2 an end cleva-
tion, and Fig. 3 a plan of our improved apparatus. In the several views shown
similar letters refer to similar parts.
For the purpose of this invention we construct duplicate tanks as a in which
we place chemical solutions such as may be suitable for purifying and softening
the water that is required to be treated. Said chemical solutions are thoroughly
mixed by paddles or agitators & that are fitted in either or both tanks, and actu-
ated by suitable mechanism such as bevel gearing c, shaft d, and pulleys e sup-
ported on the upper edges of the tanks and by the cross bars f..
An arrangement of pipes conveys the chemical solution from said tanks to a
smaller tank in which an agitator b is fitted that may be worked by a connec-
tion being formed with the aforesaid shaft & through bevel gearing j and shaft k.
The supply from the large to the small tanks is regulated by a ball tap
equivalent.
or
A connection as p is formed between the herein last named tank and a small
pump or measuring cylinder m whose size is regulated in proportion to the size
of a force pump q that is placed preferably in a line therewith for pumping the
water that is to be purified and softened, and worked by any ordinary power,
the aforesaid measuring cylinder and force pump being so connected as to work
always in ratio.
The water supply pipe to the-force pump is placed in a position convenient for
connecting a pipe thereto from the aforesaid measuring cylinder and a connec-
tion is formed between the force pump 7 and the pressure settling tank n
which may be constructed of any preferred shape, and the bottom of said tank
may be dished. Suitable scrapers arranged so that they can be revolved by gear-
ing from the top of the tank are placed within the tank, and blow out cocks are
fitted in or near the bottom of the tank for the removal of dirt or sediment at
intervals. A series of mechanical filters such as are described in the Specifica-
tion of the Patents Nos. 2384 of 1897 and 23178 of 1897, or other class of suit-
able filters, are placed contiguous to the aforesaid pressure settling tank and
connected thereto by a pipe as s. Outlet pipes h are fitted to said mechanical
filters and provided with an arrangement of valves by which water from the

page_text: filters may be forced through a bye pass v to which a box or cylinder is attached
for the reception of suitable chemicals for neutralizing purposes. In the appli-
cation of our invention the chemical solution that is intended to be used for
purifying and softening the water to be treated is drawn into the small pump
or measuring cylinder m the piston or bucket of which is worked in ratio with
the force pump by means of the bolt and pulleys m³, and on the return stroke
and at the period when the water is being drawn into the pump from the source
of supply the solution that has been drawn into the cylinder from the tank
is forced into the water supply pipe through a pipe that connects the measuring
cylinder m with the said supply pipe. The chemical solution and the water
being thus mixed in the proper proportions are then forced into the settling
tank n passing upward through the tank and through a collecting dome at the
top of said tank and thence through a series of mechanical filters as herein-
before named.
The water from these is collected by cone strainers and forced through a bye
pass when a supply of neutralizing mixture regulated by suitable valves is mixed
with the water from the aforesaid filters; 1 is the wash out pipe yy are handles
for operating the gearing for revolving the scrapers within the filters. We do
not confine ourselves to the precise relative positions of the several parts con-
stituting our invention as these may be arranged to suit space and convenience,
and in some cases as when it is not necessary that the water should be of such a
high quality or when space is an object we may dispense either with the filters
or the bye pass or both.
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 :-
1. Improved apparatus for the purification and softening of water consisting
of a combination of suitable tanks for containing chemical solutions that are con-
nected with a measuring cylinder arranged so as to work in ratio with a force
pump by which chemical solution is mixed with water in proper proportions, a
settling tank into which said mixture is forced, one or more mechanical filters
in connection therewith and an outlet pipe with a bye pass regulated by suitable
valves for containing a neutralizing chemical and mixing with the water from
the filters all substantially as herein before described and shown on the drawings.
2. Apparatus for the purification and softening of water consisting of a com-
bination with chemical tanks of a measuring cylinder, force pump, settling tank
and a filter or filters substantially as described.
3. Apparatus for the purification and softening of water consisting of a com-
bination with chemical tanks of a measuring cylinder, force pump, settling tank
and a bye pass substantially as described.
4. In apparatus that is employed for the purification or softening of water,
