Abstract

A water saving device/dual flush attachment for use in a siphon-discharge w.c. cistern comprises a small tank (3) fitted beneath the ball float and connected to the syphon by adjustable non-corrosive spring clips. The tank serves to delay the water supply at the end of the syphon action. <IMAGE>

Description

CISTERN CONTROL WATER SAVER Background and Description This device relates to w.c. cisterns which are now regarded as gross uncontrollable water wasters. As they are largely used for urinal purpose at least 6 times per day and 21 pints of water is used to flush a w.c., the tremendous waste becomes apparent. This device, made with 4 elements in brass, copper, stainless steel, pvc alloy or non corrosive materials, made for DIY fitting, is a possible answer to the problem. The device is particularly designed for insitu w.c. cisterns, both domestic and commercial, which are largely contributing to the problem. The original cistern does not employ any measures of control, and a very large number are in use today both domestic and commercial.In later years adjustable valves which control the level of water have been introduced, but whatever the level of water the supply valve continues to run from the moment the w.c.

is flushed, thereby adding a considerable amount of water to the measured quantity leaving the cistern. This device affords a measure of control to the user not previously available with any cistern. It also complies with the Water By Laws 1/1/93 when it is installed at the high level water mark, the discharge being 7 litres 0.125 ml. The device is also capable of a medium and low setting. With the upward pressure of the lever handle a measure of control on the inlet valve is possible and so introducing additional water when required.

Description of Use A drawing showing a through section of a common w.c. cistern is shown, marked 1, showing the normal components. The delayed action inner tank, marked 3, is attached to the syphon at a level which coincides with the high level water mark. The universal adjustment no. 6 fitted to the valve stem and float is then adjusted with the float in the container and suspended by the water level to keep the inlet valve closed. When the lever handle is depressed the cistern will dischargeiteload into the w.c. pan (6 seconds approx). The water escaping from the delayed action tank will then open the inlet valve to commence filling to the predetermined level. The components items no. 4, welded brass chain, will allow upward movement of the lever handle to bring item no. 5 (shown in drawing no. 2), the double angled brass arm connected to the lever arm to apply downward pressure on the inlet valve arm to provide additional water when necessary.

This latter action will follow immediately after flushing to ensure sufficient water to clear solids from w.c. pan. The 118" orifice contained in the inlet valve can be changed to 3/16" or 1/4", depending on the water pressure mains supply. The device will be made in stainless steel, brass, copper, nylon, pvc or any other non-corrosive material, to adapt to all known w.c. syphonic cisterns high or low level.

Claims

CISTERN CONTROL WATER SAVER

CLAIMS 1. A w.c. cistern, high or low level, employing a lever handle capable of upward pressure and automatically transferring downward pressure on the float arm, and restoring water supply.
2. A lever handle as described in claim 1, having the ability of upward pressure by the removal of the rigid syphon hook, and replacing with a welded link brass chain.
3. A lever handle, as described in claims 1 and 2, when held in the upward position for 15 seconds prior to flushing, will restore the normal water level (prior to use if required).
4. Employing a universal adjustment, fitting onto the end of the float arm, to which the float is then attached and can be adapted to all float valves, and working in conjunction with claims 1, 2 and 3.
5. Also employs an inner tank fitted to the syphon with s/steel clips which holds the float ball in suspension for 6 seconds, and so shutting off the water supply while the contents of the cistern are being flushed out. After 6 seconds water supply will automatically be restored, and works with claims 1, 2, 3, 4 and 5.
6. A lever handle, as described in claims 1, 2 and 3, fitted to welded brass chain, enabling upward movement of the lever handle.
7. Larger orifice (optional requirement) can be fitted in inlet valve if necessary.
8. A cistern capable of restoring normal supply by a spontaneous down/upward and hold until flushing action is complete, 6 to 7 seconds approx., as described in claims 1, 2 and 5, which action will also bypass the 6 second delay mechanism.
9. A water saving device, adaptable to almost any insitu w.c; cistern high or low level.
10. a device capable of saving 7.1/2 pints of water approx each time the lever handle is depressed. Savings can be increased by an additional 3.1/2 pints by siting the delayed action vessel lower in the cistern.
11. To be made n brass, s/steel, copper, p-/c, nylon or an non-corrosive mar

11. This device provides a much greater range of control not previously available with w.c. cisterns.

CISTERN CONTROL WATER SOWER Amendments to the claims have been filed as follows CLAIMS 1. DIY internal mechanism adaptable to any w.c. cistern, high or low level, employing a lever handle capable of upward and downward pressure and automatically transferring downward pressure on to an angle shaped arm (5), the float arm, and supplying additional water when the lever handle is raised.

2. A lever handle as described in claim I, having the ability of upward pressure by the removal of the rigid syphon hook, and replacing with a welded link brass chain which removes the stopping action in the upward movement.

3. A lever handle, as described in c'airns, and 2, when held in the upward position for 15 seconds prior to flushing, will restore the normal water level (prior to use if required), or raised immediately after the downward movement causing additional supply while the cistern is actually flushing. When the flushing action has ended, upward pressure is not required.

4. Employing a universal adjustment (6), fitting on to the end of the float arm, to which the float is then attached and can be adapted to ail float valves and working n conjunction with claims 1, 2 and 3 and allows fitting the float into the inner tank (3).

5. Also employs an inner tank (3), fitted to the syphon C with s/steel clips, which holds the float ball in suspension for 6 seconds in slowly escaping water and so shutting off the water supply while the contents of the cistern are being flushed out. After 6 seconds water supply will automatically be restored, and works with claims 1, 2, 3, 4 and 5.

5. A lever handle, as described in claims 1, 2 and 3, fitted to welded brass chain, enabiing upward movement of the lever handle.

7. A cistern capable of restoring normal supply by a spontaneous down/upward and hold until flushing action is complete, 6 to 7 seconds approx., as described in claims 1, 2 and 5, which action will also bypass the 5 second delay mechanism provided by the inner ,k (3).

8. A water saving device, adaptable to any insitu w.c. cisrnrn high cr low level.

9. A device capable of saving considerable quantities of water each time the lever handle (A) is depressed. Savings can be increased considerably by s;t:-ng the delayed action vessel 3 lower in the cistern.

-!0 This device provoc a much greater range of control not previously available with w.c. cisterns by DlY means. It can be used without items 5 and 4 With some modern inlet valves it can be lused with item 3 only.
