PROVISIONAL SPECIFICATION.
Improvements in Means and Apparatus for Periodically Discharging
a Given Quantity of Fluid.
I ALFRED CUTLACK FLANDERS, of 6 Lugard Road, Peckham, in the county of
Surrey, Marine Superintendent, do hereby declare the nature of this invention to be
as follows:-
In some trades and for domestic purposes it is often required to add a certain
quantity of fluid to another or larger body at certain periods, for example, it is
customary to introduce a small quantity of a disinfecting or sanitary fluid into the
flushing cistern of a water closet prior to each flush and it is desirable to do this
automatically.
Apparatus hitherto employed for this purpose has been apt to fail owing to the
effects of the corrosive viscous and sticky nature of the fluids generally required to be
introduced.
This invention relates to improved means for effecting the purpose consisting in a
self acting apparatus at once simple cheap and not liable to derangement from any
and which is applicable for periodically discharging any given volume of fluid
when the fluid level in a separate tank reaches any predetermined point.
cause,
To this end I use a receiver for the fluid to be added of suitable size constructed
on the principle of the "bird fountain" wherein a constant supply of fluid is supplied
to a dip cup from an elevated fountain.
The receiver is affixed to the tank at any required level which may be capable of
adjustment.
I make the dip cup to contain more fluid than is required for the actual discharge,
and I provide a displacing block capable of passing into the dip cup of the dimensions
adapted to displace and discharge therefrom the required volume.
This displacer is connected by a lever or otherwise to a float and so arranged
that as the liquid in the tank reaches a certain level the float is raised and causes
the displacer to descend into the dip cup and discharge the volume of fluid
required.
When the level in the tank falls the displacer is raised out of the dip cup and
more fluid takes its place ready for the next operation.

Improvements in Means and Apparatus for Periodically Discharging
a Given Quantity of Fluid.
I ALFRED CUTLACK FLANDERS, of 6 Lugard Road, Peckham in the county of
Surrey, Marine Superintendent, 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 :-
In some trades and for domestic purposes it is often required to add a certain quantity
of fluid to another and frequently larger body at certain periods, for example, it is
customary to introduce a small quantity of a disinfecting or sanitary fluid into the
flushing cistern of a water closet prior to each flush, and it is desirable to do this
automatically.

be introduced.
This invention relates to improved means for effecting the purpose consisting in
self acting apparatus at once simple cheap and not liable to derangement from any
cause, and which is applicable for periodically discharging any given volume of fluid
when the fluid level in a separate tank reaches any predetermined point.
I will fully describe my invention in reference to the accompanying figures which
represent two apparatus by which the principle may be carried into effect, but I wish
it to be understood I do not confine myself to the arrangements of apparatus
illustrated since the simple mechanical motions required may be produced in a variety
of ways.
Figure 1 is a sectional elevation of one form of apparatus_shown fixed to the side
of a tank or other vessel, and Figure 2 is a plan thereof. Figure 3 is an elevation
partly in section of a modified form, and Figure 4 a plan thereof. Like letters
indicate like parts in all of these figures.
A is a receiver for the fluid to be discharged and added to the main volume in
the tank T. a is the dip cup thereof and a¹ the filling aperture with screw plug for
hermetic closure. The above is constructed on the principle of the well known
"bird fountain" or "fountain inkstand" wherein a constant supply of liquid is supplied
to the dip cup from an elevated reservoir of liquid contained in the closed receiver A.
The receiver may be of any required capacity and it is or may conveniently be
furnished with an adjustable band and clip device such as is illustrated at D so that it
can be set at the proper level inside the tank T.
The dip cup a may be of any convenient shape and may be knife edged along its
upper or discharging edge; it is made to contain rather more liquid than is required
for each actual discharge, so as to give freedom of action to the displacer B which is
capable of passing into the dip cup. The displacer is of any convenient shape but
its cube dimensions are made proportionate to the full volume of required discharge so
that when it is fully submerged in the dip cup a the displacement equals the required
discharge.
Referring to Figures 1 and 2 the displacer B is pivotted at b on the dip cup a and
is directly connected by a lever L with the float F: Figures 3 and 4 represent an
arrangement taking less space such as would be applicable to a small cistern. In this
case the displacer B is fixed to a shafts capable of a part rotation in bearings s¹ sl
and cranked round the receiver A or fixed to a lever the free end of which engages
with a vertical lever L working freely in guides 9 g and carrying the float F which is
thus brought below the receiver A. In either case when the liquid level in tank T
falls the float displacer and connections take the position shown dotted and the dip
cup is at once filled with liquid from A-as the liquid in T rises the rising float
gradually depresses displacer B into the dip cup and a volume is discharged by dis-
placement just proportionate to the depth the displacer becomes submerged, and no
more; by this means any exact required amount, volume for volume, will be discharged
and no undue addition or waste takes place by a full discharge before it is required―
when however the water in T arrives at normal level as illustrated the displacer
occupies the cup a and the full intended discharge therefrom is complete.
In some cases especially with a large apparatus I apply a valve V to the flow
aperture from the receiver A to regulate the area thereof which may be operated and
adjusted by a screw and thumb piece as shown in figure 3.
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 hereinbefore described means for periodically discharging a given quantity
of fluid consisting in the displacing device substantially as set forth.
2. The combination with an apparatus known as a "bird fountain" such as is above
described of a displacer arranged and operated substantially as and for the purpose
specified

specified substantially as described and illustrated in the accompanying figures.
