PROVISIONAL SPECIFICATION.
Improvements in Flushing Apparatus.
I, FREDERIC PESCETTO, Major of Military Engineers commanding the district
of the Island of Maddalena, Sassari, Italy, do hereby declare the nature of this
invention to be as follows:-
This invention relates to that class of flushing apparatus known as water waste
preventers in which a valve is employed.
Hitherto with apparatus of this kind it has been necessary to keep the valve
raised until the water waste preventer is empty.
According to my invention I avoid this necessity by employing a valve the size
and shape of which is such that the volume of water displaced has a weight greater
than the weight of the valve so that when the valve is raised from its seat it tends
to float and the discharge opening for the water is not closed until the waste
preventer is emptied.
In carrying out the invention I provide a waste preventer provided with a cock
having a float; at the bottom of the waste preventer, is a circular opening to which
a discharge pipe is connected; the opening is so arranged as to form a seating for
the valve which may consist of a hollow india rubber ball.
When the waste preventer is empty the valve falls to its seat by its own weight
and as the waste preventer fills the pressure of the water facilitates the action of
the valve if the weight and size of the valve have been suitably determined.
To prevent the valve rising to the surface of the water, whereby the chain to
which it is connected might become entangled with the float rod I provide the
valve with a kind of cage.
When it is desired to discharge the water from the waste preventer, even when
it is not full, by pulling down the chain for an instant the valve is slightly raised
and will not fall to its seat until the waste preventer is completely emptied.
For flushing water closets, urinals, &c., the waste preventer is placed above on a
suitable support and the discharge pipe is in direct communication with the basin
or pan to be flushed.

COMPLETE SPECIFICATION.
Improvements in Flushing Apparatus.
I, FREDERIC PESCETTO, Major of Military Engineers, commanding the district
of the Island of Maddalena, Sassari, Italy, 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 :-
This invention relates to that class of flushing apparatus or cistern in which
a valve has to be lifted for discharging the contents of the cistern.
Hitherto with apparatus of this kind it has been necessary to keep the valve
raised until the cistern is empty..
According to any invention I avoid this necessity by employing a valve the
volume of water displaced by which has a weight greater than the weight of the
valve so that when the valve is raised from its seat it tends to float and the discharge
opening for the water is not closed until the cistern is emptied.

page_text: To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing which represents a
section of a flushing apparatus having a valve arranged according to my invention.
In carrying out the invention I provide a cistern a having a ball cock b. At
the bottom of the cistern a is a circular opening to which a discharge pipe c
is connected; the opening is so arranged as to form a seating for the valve
which may consist of a hollow balle attached to a cord or chain f carried by
one end of an oscillating lever pivotted at to the edge of the cistern a, the
other end of the lever 9 having attached thereto a cord or chain whereby the
valve is lifted.
When the cistern a is empty the valve e falls to its seat by its own weight and as
the cistern fills, the pressure of the water facilitates the action of the valve if the
weight and size of the valve have been suitably determined.
To prevent the valve e rising to the surface of the water, whereby the chain
to which it is connected might become entangled with the rod of the float j. I
provide the valve e with a kind of cage k.
When it is desired to discharge the water from the cistern «, even when it is not
full, by pulling down the chain i for an instant the valve e will be slightly raised
and will not fall to its seat until the cistern a is completely emptied.
For flushing water closets, urinals &c. the cistern a is placed above on a suitable
support and the discharge pipe c is in direct communication with the basin or pan
to be flushed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The combination with flushing apparatus of a valve, the volume of water
displaced by which is of greater weight than the valve so that when the valve
is raised from its seat it tends to float and the discharge opening for the water
is not closed unti the cistern is emptied substantially as hereinbefore described.
2. The improved flushing apparatus having a valve arranged and operating in
the manner set forth and illustrated in the accompanying drawing.
