An Improved Sanitary Flushing Apparatus.
1, ALEXANDRE RICILARDY, of 7, Port de l'Ecu, Vienne (Isère), in the Republic
of France, Plumber, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to replace with advantage the ordinary flush-
ing apparatuses of rectangular form operated by a pull and float which in addition
to the space which they require, and their inartistic appearance have also numerous
drawbacks, such as accidents caused by flooding of rooms, capricious working
and the like.
The apparatus which will now be described, however, avoids all these draw-
backs and is further of absolute security, by reason that the water is only
admitted automatically to its flushing reservoir during the time that, the seat is
occupied.
The said apparatus is composed simply of a three-way tap, the first port of
which is in communication with the water supply pipe, and the second alter-
nately with the water coming from said pipe and passing into the flushing reser-
voir proper and with the neck or connection of the basin by means of the third
port, the area of which is equal to that of the second port.
In order that the pressure of the main pipe may be imparted to the water of
the reservoir the latter has in its interior a pipe open at the upper end and carrying
at the top, a valve capable of automatically closing the upper part of the said
reservoir.
When the flushing apparatus is operated, the water rises in the reservoir
communication pipe gradually filling the pipe of the valve, and simultaneously
lifts the latter, until it is pressed against the opening of the reservoir and produces
a complete closing. The air contained in the upper part of the pipe is in con-
sequence under the same pressure as the pipe, plus the pressure of the body of
air imprisoned between the level of the water and the upper part of the reservoir.
In this way the advantage is obtained that the said reservoir may be fixed at
any suitable height, according to the arrangement desired whilst still ensuring
the desired pressure for the water flush.
The apparatus proper is fixed behind the neck or connection of the pan or
basin and below the fixed part of the lid of the closet by means of horizontal lugs.
or brackets. Under these conditions the water supply pipe is placed at the rear
art of the said pan or basin. The hollow plug of the three-way tap is connected
t its ends to two levers corresponding with the movable part of the closet lid.
When it is desired to produce a flush it is sufficient to raise the lid in order to
urn the plug of the tap by means of the levers and allow of the filling of the
eservoir which requires about one minute. By then lowering the lid, the plug
f the tap is turned, thus uncovering the opening into the pan, and allowing
he flush to take place, and a perfect cleansing to result.
Where the seat or lid is simply arranged, slightly held up by means of springs,

page_text: it is sufficient to sit down on the seat in order to produce the same result, that is
to say, to cause the plug to turn and to consequently produce the flush.
In order always to have a tight closing of the plug of the tap, the latter is
provided at its largest end with an arrangement having for its object to push
the conical plug to the end of its casing with the sole object of obtaining auto-
matically a perfect fit. This result is obtained by means of a spiral spring
located at the front part of the tap, between the end of the plug and a recessed
cover. At the opposite end, a grooved or recessed washer mounted on the squared
end of the plug, engages a stop pin to limit the extent of turning of said plug,
and thus always to cause the openings for the passage of the water to exactly
register.
The tap is connected with the water supply pipe by an ordinary union in
three pieces, and to the neck or connection of the pan or basin by a connection
of india-rubber.

I, ALEXANDRE RICHARDY, of 7, Port de l'Ecu, Vienne (Isère), in the Republic
of France, Plumber, 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 has for its object to replace with advantage the ordinary flush-
ing apparatuses of rectangular form operated by a pull and float which in addition
to the space which they require, and their inartistic appearance have also numerous
drawbacks, such as accidents caused by flooding of rooms, capricious working
and the like.
The apparatus which will now be described, however, avoids all these draw-
backs and is further of absolute security, by reason that the water is only
admitted automatically to its flushing reservoir during the time that the seat is
occupied.
The said apparatus which is shown in the accompanying drawings in which,
Figure 1 is a vertical longitudinal section,
Figure 2 a transverse section, and
Figure 3 a plan view
is composed simply of a three way tap, the first port A of which is in com-
munication with the water supply pipe D, and the second B alternately with the
water coming from said pipe and passing into the flushing reservoir E proper
and with the neck or connection of the basin by means of the third port C, the
area of which is equal to that of the second port B.
In order that the pressure of the main pipe may be imparted to the water of
the reservoir, the latter has in its interior a pipe open at the upper end and
carrying at the top, a valve capable of automatically closing the upper part of
the said reservoir.
When the flushing apparatus is operated, the water rises in the reservoir com-
munication pipe F gradually filling the pipe of the valve, and simultaneously
lifts the latter, until it is pressed against the opening of the reservoir and produces
a complete closing. The water contained in the upper part of the pipe is in
consequence under the same pressure as the pipe, plus the pressure of the body

page_text: of air, imprisoned between the level of the water and the upper part of the
reservoir.
In this way the advantage is obtained that the said reservoir may be
fixed at any suitable height, according to the arrangement desired whilst still
ensuring the desired pressure for the water flush.
The apparatus proper is fixed behind the neck or connection of the pan or
basin and below the fixed part of the lid of the closet by means of horizontal
lugs or brackets P. Under these conditions the water supply pipe D, is placed
at the rear part of the said pan or basin. The hollow plug S of the three-way
tap is connected at its ends to two levers G and H corresponding with the
movable part of the closet lid. This is an ordinary arrangement. When it is
desired to produce a flush it is sufficient to raise the lid in order to turn the plug
of the tap by means of the levers G and H and allow of the filling of the reservoir
(position shown in Figure 2) which requires about one minute. By then lower-
ing the lid, the plug of the tap is turned, by the levers G & H thus uncovering
the opening into the pan, and allowing the flush to take place, and a perfect
cleansing to result.
Where the seat is simply arranged, slightly held up by means of springs, it is
sufficient to sit down on the seat in order to produce by the weight of the person
the same result, that is to say, to cause the plug to turn and to consequently
produce the flush.
In order always to have a tight closing of the plug of the tap, the latter is provided
at its largest end with an arrangement having for its object to push the conical
plug to the end of its casing with the sole object of obtaining automatically a
perfect fit. This result is obtained by means of a spiral spring located at the
front part of the tap, between the end of the plug S and a recessed cover T. At
the opposite end, a grooved or recessed washer R mounted on the squared end of
the plug, engages a stop pin L to limit the extent of turning of said plug, and
thus always to cause the openings for the passage of the water to exactly register.
The tap is connected with the water supply pipe by an ordinary union Zin
three pieces, and to the neck or connection of the pan or basin by a connection
of india-rubber.
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:-
An improved flushing apparatus characterized by the arrangement of a three
way tap, the plug of which is adapted to be actuated automatically by the lid of
the closet pan, said tap communicating with an upper reservoir of any suitable
form, the whole substantially as hereinbefore described and shown in the accom-
panying drawings.
