Improvements in Flushing Cisterns.
I, GEREMIA GIORDANO, of 16, Via S. Dalmazzo, Turin, in the Kingdom of Italy,
Captain of Artillery, 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; -
My invention relates to an improvement in flushing cisterns, tanks, or receptacles
adapted for various uses where a body of liquid is required to be discharged there-
from when desired but particularly for use with water closets.
My invention is illustrated in the accompanying drawing in which:-
Fig. 1 is a section of an apparatus constructed according to my invention the
parts being in the position when the apparatus is not discharging or is at rest.
Fig. 2 is a similar view with the parts in the position when the apparatus is
discharging.
A is the cistern or receptacle having a discharge pipe B, and inlet pipe C, the
latter being provided with a valve E of some suitable form, that shewn being a
well known and convenient one.
To the movable part of the valve is connected a lever H pivoted at I and such
lever H carries a chain or handle F, and a closed box or float D.
In the arrangement shewn the float contains an open cylinder or bell G adapted
to cover the open end of pipe B which projects into the cistern.
In Fig. 1 the apparatus is at rest and the liquid is level with the top of pipe B,
the float D is partly submerged in the liquid and is held at an angle as shewn so
that the valve E is kept closed by means of lever H.
When the cistern is to be
discharged the chain is pulled down bringing with it the lever H and forcing
the float into the liquid which thus raises the level of same forces a portion down
the pipe B and starts a siphoning action in pipe B and bell G until the cistern is
empty or nearly empty when the valve E will be opened by lever H and the cistern
will begin to fill again from pipe C the float gradually rising again into the position
shewn in Fig. 1 when the valve E is shut off again.
It is evident that the bell G may be attached to the float outside of same or
that the floating gear may be guided vertically without the lever 1, the valve E
being then attached to the float in any convenient way, or that the chain may be
replaced by a rod which will also serve to raise the float positively so as to inter-
rupt the action of the siphon.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a flushing cistern the combination with a float, of a bell carried thereby,
an inlet pipe, a valve for same controlled by the float, and a discharge pipe entering
the bell and in which a siphoning action is set up by operating the float and bell,
substantially as described.
2. In a flushing cistern the combination with a float, of a bell formed inside

page_text: of same, a lever carrying such float and bell, an inlet pipe, a valve for same
controlled by said lever, and a discharge pipe entering the bell and in which a
siphoning action is set up by operating the float and bell, substantially as described.
