PROVISIONAL SPECIFICATION.
Improvements in Flushing Appliances for Urinals, Water Closets,
and the like.
We. THOMAS YORKE, Plumber, and WILLIAM PARE, Surveyor, both of Rushden,
in the County of Northampton, do hereby declare the nature of our said invention
to be as follows:-
The object of our invention is to effect improvements in flushing appliances
for urinals, water closets, lavatories and other places that require flushing, whereby
the usual hanging chain and pull and other moving fittings are dispensed with,
and the action of the flushing appliance rendered noiseless.
According to my invention we fit a bell-shaped vessel over the intake end of
an ordinary S or M shaped trap or syphon enclosed in the usual tank, the dis-
charge end of the trap being connected with the flush. pipe. The upper end of
the bell is connected with a tube, preferably of small bore, which passes a short
distance into the intake end of the trap or syphon and is carried down the wall
to a convenient position where a push valve (of a similar construction to the spring
push lavatory taps) is fitted. From the push valve the tube is carried to and
connected with the flush pipe or closet pan. The tube passes through the bottom
of the tank and a small hole is formed in the tube immediately above and close
to the bottom of the tank; Below the tank the tube is preferably bent round
to form a complete turn so as to ensure and maintain a water seal in the tube.
The water in rising in the cistern or tank, compresses the air in the bell, the
water in the tank and tube preventing the escape of the air from the hole in
the small bore tube. On pressing the push valve, a small quantity of water is
allowed to escape from the tube thus relieving the bell of the air pressure and
upsetting the equilibrium whereby the syphon is started.
It will thus be seen that should the push valve be held during the discharge
the continuity of the flush is not broken and the air is prevented from escaping
during the filling of the tank, the small hole in the tube serving to supply the
small bore tube with sufficient water to ensure its proper action.

Price 8d1

page_text: and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of our invention is to effect improvements in flushing appliances
for urinals, water closets, lavatories, and other places requiring to be flushed, whereby
the working parts are reduced to a minimum; the cistern is rendered silent in
action; the apparatus is neat and compact, and the cistern may be fixed at any
reasonable distance from the closet, if desired.
And in order that our said invention may be particularly described and ascer
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is an elevation partly in section showing our invention fitted with a
bell-shaped vessel over the intake end of the syphon, and Fig. 2 is a similar
elevation, in which the bell is dispenced with, and an extra leg is added, forming
an M shaped syphon.
a is the flushing cistern. 6 is an S syphon open to the bell at the intake
end, and to the flushing pipe d at the delivery end. e is a small pipe connected
with the bell at f and carried through the cistern to a spring push diaphragm g
(of a similar construction to the spring push lavatory taps). From the push
valve the tube e is carried to and connected with the flush pipe, as shown by
solid lines, or to the closet pan, as indicated by dotted lines. At e¹ the tube is
preferably bent round to form a complete turn so as to ensure and maintain
a water seal in the tube. At a small hole is formed in the pipe e. h is the
ordinary ball valve; supplying the cistern.
The water in rising in the cistern compresses the air in the bell c and in the
pipe e. Water enters the pipe e through the hole e. On pressing the push
valve g, a small quantity of water escapes from the tube e, thus relieving the
bell of the air pressure, and acting as an air syphon. The water in the cistern
being at a higher level than the crown of the bell, the syphonic action of the
water is started, emptying the contents of the cistern through the flush pipe d.
In the modification shown in Fig. 2 the additional leg c¹ performs a similar
function to that of the bell c.
. Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. The improvements in flushing appliances. for urinals, water closets, and the
like, substantially as and for the purposes described.
2. In flushing appliances as aforesaid, the combination of an S syphon b, a
bell cor pipe c', a pipe c communicating with the syphon at f and with a push
valve at 9, and a ball cock h, all fitted to a cisterna and flush pipe d, and severally
operating substantially as herein before described and illustrated by the drawings.
