Improved Silent Flushing Apparatus for Water Closets and Urinals.
I, JOSEPH CHALLENDER, No. 12, Moss, Lane West, Moss Side, Manchester,
Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in flushing apparatus to water closets
an urinals acting silently to delivery without valves syphon's or levers inside
cistern and without pull and chain except from choice which invention may be
applied to other uses.
The system consists of a float in the cistern which acts automatically in con-
nection with a valve and catch contained in a metal box placed in a convenient
position between the cistern and water closet or urinal. The valve can be opened
and brought into use by a push or button hereinafter described by raising or
lowering the water closet seat the opening or closing of a door or other mechanical
contrivances. The valve box may be constructed any shape in one or more peices
but for the purposes of description in this case it shall be in two peices upper
& lower" which can be joined together by flange or otherwise and having an
inlet and outlet sufficiently large for the flushing water to pass freely. The lower
part contains an ordinary valve seating and also a valve attached to a bar or
swivel which turns easily and is kept in position with lug's or steps. The ends
of the bar or swivel are cranked or so made to receive a rod connected with the
button or push beforementioned which is attached to the valve box and works
through a stuffing box. This rod and button is not connected with but simply
opens the valve by being pushed and when released returning to its normal position
by the aid of a spring. In the upper part immediately over the valve but just
under the inlet is a catch or lever made at right angles or V shape of which one
side is weighted the other side being opened out like a spreader or fan. the apex
work's loosely on a spindle and when not in use the fan stands out horizontally
under the inlet of valve box. To use this arraingement you press the button
outside "inwards" which forces open the valve the water descending bear's the
fan down in front of and prevents the valve closing until the water closet or
urinal is flushed. The flushing over the weighted side falls lifting the fan to it
original position releasing the valve which closes automatically. In connection
with this valve and catch there is a float in the cistern large enough to cover
the end of flush pipe therein an air tube is fixed through and projects on both sides
of float and when the cistern is charged with water the float is buoyed over the
discharge pipe and is kept in position by the air tube and a guide when the valve
is opened the float descends with the water on a prepared seating closing the flush
pipe and preventing the "swirl" or sucking noise usually made by escaping
water from ordinary cisterns. The flushing pipe between valve and cistern fills
slowly through an aperture from the cistern and the float swims on the water
supplied thereto at the top of air tube near the underside body of float is an air
escape which prevents bubbling and noise. The cistern is constructed for the

Improved Silent Flushing Apparatus for Water Closets and Urinals.
I, JOSEPHI CHALLENDER, of 12, Moss Lane West, Moss Side, Manchester, in the
County of Lancaster, Sanitary Engineer, do hereby, declare the nature of this inven-
tion 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 improvements in flushing apparatus for water closets
and urinals, the object being to dispense with valves, syphons or levers inside
the cistern and the chain or pull, excepting from choice, thus rendering the
closet silent up to delivery.
My improved system or flushing water closets and the like consists of a float
in the water cistern which acts automatically in connection with a valve and catch
inside a metal box containing. said valve which is placed in a convenient position
between the water cistern and the closet (or urinal).
The said valve can be opened and brought into use by a push or button here-
inafter described, or if desired, by lowering or raising the closet seat or by the
opening or closing of a door or other mechanical contrivances.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings, showing my invention as applied
to a water closet, and marked with letters of reference indicating like parts in the
various figures, Fig. 1 being a longitudinal section of the water supply cistern, Fig. 2 a
vertical section, Figs. 3 & 4 sectional plans at lines A-A and B-B of Fig. 1
respectively, of the valve box inserted into the pipe which conveys the water from
the cistern to the water closet. Fig. 5 is a side view and Fig. 6 a plan of a
modification in the shape of the said valve box, and Fig. 7 at a reduced scale a
diagram of the whole flushing system.
In carrying out my invention and referring to Figs. 1, 2, 3, 4 & 7, A is the
box containing the said valve, which box may be constructed in any shape, in one
or more parts, say, in two parts, as shown in Figs. 2, 3 & 4, an upper one a and a
lower one a¹, which can be joined together by flanges or otherwise and having an
inlet 6 and outlet 61 sufficient large for the flushing water to pass freely; or the
said valve box may be formed, as shown in Figs. 5 & 6, round in front and straight
at the back and with a lid a³ screwed thereto...
The lower part a¹ contains an ordinary valve seating c and a valve d attached
to a bar or swivel e which turns easily and is kept in position by lugs or steps f.
The ends of the bar or swivel e are cranked upwards or, so made as to form pro-
jections e, el adapted to be acted upon by the forked ends g, g of a rod g¹ con-
nected with the button or push g2 which rod, is mounted in, a
formed on the valve box A. This rod and button are not connected with, but
stuffing box h
simply open the valve d when pushed against, the projections e¹, e¹ and when
released are returned to their normal position by a spring i.
In the upper part. a, immediately over the valve d but just under the inlet b,
is fulcrumed to a spindle k, a catch or lever l, one side of which, is weighted and
the other side opened out like a spreader or fan, and slightly turned, at its edge
which when at rest stands out horizontally under the inlet of the valve box A,
see full lines Fig. 2.
In connection with this valve and catch, a float m is employed in the water

page_text: cistern, see Fig. 1, large enough to cover the orifice of the flush pipe o secured
therein, which latter is formed with a seating o', whilst the said float carries an
air tube m¹ projecting on both sides and vertically guided by the bridge o².
When the cistern n is charged with water, the float is buoyed over the flush
pipe o and kept in this position whilst the column of water in the pipe rests
upon the valve d in the box.
Below the underside of the float m, air holes m² are formed in the air tube m¹,
which permit the air accumulated above the water in the flush pipe o when nearly
full, to escape through the air tube m¹ when the float is on its seating so as to
prevent bubbling and noise.
The operation of the system is as follows:-
When it is desired to flush the water closet p the button 9 outside the valve
box A is pressed in and immediately released, which action causes the valve d
in the box A to be lifted into the position shown in dotted lines Fig. 2.
The column of water in the flush pipe o being then allowed to descend, presses
the front or fan end of the catch lever down upon the end of the valve d and
retains same in its raised position until the closet is flushed.
As the water descends in the cistern the float m descends also and when the
cistern is nearly empty the float closes the orifice of the flush pipe whereby the
swirl and sucking noise usually created by the escape of water in ordinary cisterns
is obviated.
When the water has left the flush pipe o, the weighted catch is freed from its
pressure and the weight of the catch then raises its fan end off the valve d and
allows same to fall and close.
The water in the cistern m then flows slowly through the apertures
formed
in the upper end of the flush pipe o into the latter and when charged the float
rises off its seating o¹ again.
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:-
1st. In apparatus for flushing water closets, urinals and the like, in combination
with a water cistern n a float m having an air escape tube m¹ formed with side
holes m³, which float is adapted to close the inlet orifice of the flush pipe o as the
latter discharges its contents, all substantially as and for the purpose set forth.
2nd. The valve box A containing a valve d adapted to be raised by a push
rod g, g and retained in that position by weighted catch 1, pressed thereon by
the column of water descending the flush pipe o and releasing it when freed from
the pressure of the said column of water, all substantially as set forth.
3rd. In combination, the cistern n having a float m, the valve box A containing
a valve d, raised by a push rod g, g¹ and retained by a weighted catch / subjected
to the action of the column of water in the flush pipe o, which valve box is
inserted into the latter, all substantially as and for the purpose set forth.
