Improvements in Flushing Valves or Apparatus for Discharging
Limited Quantities of Water from Supply Pipes.
I, JASPER WETTER, Patent Agent, of 433, Strand, London, do hereby declare
the nature of this invention to be as follows:---
This invention relates primarily to water waste preventers or apparatus for
delivering a limited quantity of flushing water to water closets, at the required
pressure without the use of a cistern or ball valve, but it is applicable also for
other analogous purposes.
In the following description reference will be made to the accompanying drawings,
in which
Fig. 1 is a longitudinal vertical section and Fig. 2 a plan of an apparatus
embodying the invention, while
Figs. 3 and 4 show certain details on a larger scale.
The apparatus chiefly comprises a vertical cylinder A. containing an inlet valve B,
a horizontal cylinder C containing a discharge valve D, and an intermediate chamber
or casing E containing a flexible diaphragm e.
The cylinder A communicates at the side with the water supply pipe G, it is
screwed at the bottom into a socket of the casing E and closed at the top by a screw
cap F containing a flexible washer. The valve B has the shape of a short vertical
tube provided at the top with a sharp annular edge or mouth, as shown by Fig. 3,
and at the bottom with a tubular extension which passes through the diaphragm E
and is attached to the same by a nut e¹ and washer 2. The diaphragm casing E is
screwed upon an upward extension of the cylinder C and contains a sleeve H which
surrounds a part of the tube and is connected with the valve B by a flexible
waterproof envelope h. The flexible waterproof diaphragm e, if made of leather,
is pressed downward by a helical spring shown in Fig. 3, but if made of metal, it
is simply bulged downward and resumes this position by its own elasticity, after
it has been flattened or bulged upward.
The cylinder C has in front an annular enlargement c which communicates at cl
with an upright vessel or tubular reservoir not shown in the drawing, while the
open front end of the cylinder is provided with a screw socket for the discharge
pipe J which has at its inner face an annular packing ring placed opposite the face
of the valve D. This valve has in front a sharp circular edge and at the back an
axial extension or rod d guided at its rear end in a socket piece k. The latter is
screwed into the base plate or frame K which supports in front the cylinder C.
The valve rod d is surrounded by a helical spring enclosed in the casing k and
serving to press the valve forward against the annular packing ring j. For with-
drawing the valve and therefore opening the outlet J, I employ a lever, not
shown in the drawing, which passes vertically through the frame K and through
the rectangular opening d¹ of the valve rod and is capable of oscillating in a
vertical plane.
Between the casing K and the cylinder C is held the flange of a short sleeve
which surrounds a part of the valve rod and is connected with the valve D by a
flexible waterproof tube which closes tight at both ends and is capable of com-
pression and expansion, thus performing the function of a stuffing box, like the
compressible tube / described above.
The apparatus works as follows
:-
In the starting position, the valve D is closed and the valve A open, pressure

page_text: water enters the cylinder through the pipe G, and rises to the mouth of the valve B;
subsequently it descends through the valve B aud tube 6 into the cylinder C, and
after having filled the same, it passes through the lateral outlet e' into the vertical
storage pipe or intermediate reservoir connected with the same, as mentioned
above. When the water in the latter has reached the desired level, its pressure
is sufficient to overcome the clasticity of the downward bulged diaphragm
the pressure of the spring e², thereby lifting the tube and valve B and pressing
the latter against the washer f, so as to prevent the further flow of water into the
valve, (see Fig. 3).
e or of
The apparatus is now ready for use, and is set in action, when desired, by with-
drawing the valve D, by means of the hand lever passing through the slot d¹ of the
rod. d. The valve D is now in the position shown by Fig. 1 and allows the water
contained in the vertical storage pipe or reservoir to escape through the space c
into the discharge pipe J, which leads to the flushing pan or other receptacle.
After the water has passed out, and thereby the pressure on the bottom of the
diaphragm e has been reduced, the diaphragm descends again and thereby opens
the valve B again at the top, so as to allow water to enter.

Improvements in Flushing Valves or Apparatus for Discharging
Limited Quantities of Water from Supply Pipes.
1, JASPER WETTER, Patent Agent, of 433, Strand, London, do hereby declare
the nature of my 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 primarily to water waste preventers or apparatus for
delivering a quantity of flushing water to water closets, at the required pressure,
without the use of a cistern or ball valve, but it is applicable also for other
analogous purposes.
In the following description reference will be made to the drawings filed with
the Provisional Specification, in which
Fig. 1 is a longitudinal vertical section and Fig. 2 a plan of an apparatus
embodying the invention, while
Figs. 3 and 4 show certain details on a larger scale.
The apparatus chiefly comprises a vertical cylinder A containing an inlet valve B,
a horizontal cylinder C containing a discharge valve D, and an intermediate
chamber or casing E containing a flexible diaphragmn e.
The cylinder A communicates at the side with the water supply pipe G, it is
screwed at the bottom into a socket of the casing E and closed at the top by a screw
cap F containing a flexible washer f. The valve B has the shape of a short
vertical tube provided at the top with a sharp annular edge or mouth, as shown by
Fig. 3, and at the bottom with a tubular extension which passes through the
diaphragm e and is attached to the same by a nut e¹ and washer e². The diaphragm
casing E is screwed upon an upward extension of the cylinder C and contains a
sleeve H which surrounds a part of the tube band is connected with the valve B
by a flexible waterproof envelope h. The flexible waterproof diaphragm e, if made
of leather, is pressed downward by a helical spring shown in Fig. 3, but if made of
metal, it is simply bulged downward and resumes this position by its own elasticity,
after it has been flattened or bulged upward.
The cylinder C has in front an annular enlargement c, which communicates at c¹
with an upright vessel or tubular reservoir not shown in the drawing, while the
open front of the cylinder is provided with a screw socket for the discharge pipe J
which has at its inner face an annular packing ring placed opposite the face of the

page_text: valve D. This valve has in front a sharp circular edge, and at the back an axial
extension or rod d guided at its rear end in a socket piece k. The latter is screwed
into the base plate or frame K which supports in front the cylinder C. The valve
rod d is surrounded by a helical spring enclosed in the casing k and serving to
press the valve forward against the annular packing ring j. For withdrawing the
valve and therefore opening the outlet J, I employ a lever, not shown in the
drawing, which passes vertically through the frame K and through the rectangular
opening of the valve rod and is capable of oscillating in a vertical plane.
Between the casing K and the cylinder C is held the flange of a short sleeve
which surrounds a part of the valve rod and is connected with the valve D by a
flexible waterproof tube which closes tightly at both ends and is capable of com-
pression and expansion, thus performing the function of a stuffing box like the
compressible tube / deseribed above.
The apparatus works as follows:-
In the starting position, the valve D is closed and the valve A open, pressure
water enters the cylinder through the pipe G, and rises to the mouth of the
valve B subsequently it descends through the valve B and tube b into the
cylinder C, and after having filled the same, it passes through the lateral outlet e¹
into the vertical storage pipe or intermediate reservoir connected with the same,
as mentioned above. When the water in the latter has reached the desired level,
its pressure is sufficient to overcome the elasticity of the downward bulged
diaphragm e or of the pressure spring e², thereby lifting the tube 6 and valve B
and pressing the latter against the washer f, so as to prevent the further flow of
water into the valve, (see Fig. 3).
The apparatus is now ready for use, and is set in action, when desired, by with-
drawing the valve D by means of the hand lever passing through the slot d' of the
rod d. The valve D is now in the position shown by Fig. 1 and allows the water
contained in the vertical storage pipe or reservoir to escape through the space c
into the discharge pipe J, which leads to the flushing pan or other receptacle.
After the water has passed out and thereby the pressure on the bottom of the
diaphragm e has been reduced, the diaphragm descends again and thereby opens
the valve B again at the top, so as to allow water to enter.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A flushing apparatus having the characteristic feature, that when the water
reservoir is full, the pressure of the water in the same acts on one side of a flexible
plate connected with the inlet valve, and thereby cuts off the supply of pressure
water to the apparatus, substantially as described.
2. The means for regulating the supply of feed water, chiefly comprising a
flexible plate e exposed to the pressure of water in the reservoir, and a tubular
valve B situated in the pressure cylinder A and open at both ends, said valve,
when in its closing position, being pressed upon the valve seat by the plate e
3. The means for closing the discharge pipe, chiefly comprising an equilibrated
horizontally moveable valve D, a spring 1 for pressing on the spindle of the said
valve, a flexible connecting tube m for keeping off the water, and a reversing or
operating lever, substantially as described.
4. The use of a flexible connecting tube has a packing between the valve body B
and the lower end of the valve chamber, substantially as described.
