Supplied to Cisterns or Tanks.
I, CHARLES EDWARD GITTINS of 100 Fenchurch Street in the City of London,
Filter Manufacturer, do hereby declare the nature of this invention to be as
follows:-
At the present time lime water or other solution is commonly added to hard waters
to soften them, but to do this in the cisterns used for supplying dwelling houses
requires care and attention and is frequently neglected.
The object of the invention is to effect by automatic apparatus the softening of
water as it is supplied to a cistern. For this purpose I cause the water as it issues in
a stream from a ball supply cock to draw along with it a much smaller stream of
whatever solution is being used for effecting the softening.
The stream of mixed water and solution I cause to be received into a settling cistern
or cisterns at one side of the water supply cistern in which it is allowed to settle and
only to pass of into the main cistern through an overflow outlet. This settling cistern
I divide into two compartments by a vertical partition-the supply enters into one
compartment and passes off from the top of the other-there being a small opening at
the bottom of the vertical partition to allow water to pass from one compartment to
the other.
The ball which controls the supply cock floats in the main cistern. A tumbling
weight or like appliance may be used to cause the ball cock to be always either full on
or closed.
To cause the stream of water as it flows along the outlet from a bail cock to draw
along with it a small stream of solution I place centrally within the ball cock outlet a
small tapering nozzle, the smaller end of the nozzle is towards the outlet orifice, the
arger end I carry through the outlet pipe and lead a pipe downwards from it into a

page_text: receptacle containing a supply of the solution. When the cock is open the stream of
water passing along the outlet pipe draws along with it from the tapering nozzle a
small stream of the solution and both streams pass together to the outlet orifice, or the
solution might be supplied in a thin annular stream around a central stream of water.
Preferably I close the end of the outlet pipe and form the outlet orifice on one side so
that the two streams may the better be made to mix together as they issue into the
settling cistern.
By making the outlet end of the tapering nozzle smaller or larger the proportion of
solution added to the water may be varied as may be required.

I CHARLES EDWARD GITTINS of 100 Fenchurch Street in the city of London
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 :-
At the present time lime water or other solution is commonly added to hard waters
to soften them, but to do this in the cisterns used for supplying dwelling houses
requires care and attention and is frequently neglected.
The object of this invention is to effect by automatic apparatus the softening of
water as it is supplied to a cistern. For this purpose I cause the water as it issues in
a stream from a ball supply cock to draw along with it a much smaller stream of
whatever solution being used, in the proper proportion for effecting the softening.
The apparatus for effecting this object is shown in two forms at Figs. 1 and 2
Sheet 1 of the accompanying drawings.
Fig. 1 a is the pipe through which comes the supply of water and to the end of this
pipe is screwed the outlet pipe b, centrally within this pipe 6 I fix the tapering
nozzle c the smaller end being towards the outlet orifice 61; the larger end being
carried through the outlet pipe and provided with a screw thread for the purpose of
connecting to it the pipe d which leads downwards into a receptacle containing a
supply of the solution. Thus when the cock is open the stream of water in passing
through the outlet b sucks or draws along with it from the tapering nozzle c a small
stream of the solution and both streams pass along together to the outlet orifice 6'.
By making the outlet end of the nozzle c smaller or larger the proportion of solution
may be varied as required.
According to the construction shown in Fig. 2 the water passes through the
tapering nozzle c and the pipe d leading from the solution enters at the side of the
outlet pipe 6 as shown; and in this case the solution will be supplied in a thin
annular stream around the central stream of water-The proportion of solution drawn
in will be varied (in this construction) by closing or opening the annular orifice by
raising or lowering the tapering nozzle c.
In cases where the pressure of the water is insufficient to draw in the solution a
second nozzle may be made within nozzle c and through one of these nozzles steam
will be passed to assist in the drawing in of the solution.
Preferably I close the end of the outlet pipe band form the outlet orifice on one
side so that the two streams may the better be made to mix together as they issue into
the settling tank.
In sheet 2 of the drawings is illustrated a water softening plant according to this
invention Fig. 1 being a plan and Fig. 2 a sectional elevation.
The softening solution will be contained in the receptacle or tank S in which may

page_text: also be placed an agitator worked by any convenient means to keep the solution
properly mixed.
The stream of mixed water and solution pass from the outlet pipe b b' into the
settling cistern or cisterns A in which it is allowed to settle and only to pass off into
the main cistern B through the overflow outlet C. This settling cistern I divide into
two or more compartments by a vertical partition or partitions D-the supply enters
into the first compartment and thence through each successively until the cistern B is
reached. Openings are made at the bottoms of the partitions to allow the water to
pass from one compartment to the other, but in the case as shown in the drawings
where more than two partitions are used I prefer to make these openings alternately
at the bottom and top.
The ball E floating in cistern B controls the supply cock and if necessary a tumbling
weight or like appliance may be used to cause the ball cock to be always full on or
closed.
For convenience of cleansing the settling tanks of the precipitated lime and other
impurities I form the bottom of the tank sloping and make an outlet hole leading to
a trough y underneath the tank. The hole is kept closed by the valve z which can
be raised or lowered by the hand wheel o as desired.
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 :-
Firstly. In water softening apparatus, the means employed for automatically
supplying and mixing the softening solution in proper proportions with the water as
it flows into the tank or cistern as herein described with reference to the drawings.
Secondly. The combination of the various parts forming my improved apparatus for
effecting the softening of water as herein described and shown in the annexed
drawings.
