Abstract

An overflow device for a bath, basin or sink comprises a tube (A) fitted to an overflow outlet, the bottom of said tube leading to a collecting vessel (B) which is connected by a pivoted arm (D) to the waste fitting (G) of said bath, basin or sink such that when the collecting vessel fills with overflow water, the arm pivots to release the waste filling. <IMAGE>

Description

ANTI-OVERFLOW This invention relates to the waste and overflow system of a bath, sink or basin. With present day systems the overflow relies on the water flow through a hole located near the top of a bath, sink or basin, then down a pipe and into the main waste pipe. The amount of flow is relativly slow, due to the fact, there is very little pressure behind the water, because the overflow outlet is at the waters higher level. As a result the water level fuelled by the fast running taps passes the overflow outlet and continues to rise until it reaches the top of bath, sink or basin when it starts flowing onto the floor.

This invention uses the water in the overflow to open the main plug of the bath, sink or basin. Thus allowing a far greater amount of water to leave the bath, sink or basin with a far greater pressure when a certain water level has been reached. This is done automaticaly and prevents the bath, sink or basin overflowing when using fast running taps in most cases.

This overflow system consists of an overflow pipe A, leading down to a collecting bucket B, which can slide up and down inside pipe C. The collecting bucket B has a small clearance inside pipe to allow a slow passage of water past the side. Underneath bucket B is the lever arm D which runs along the inside of the horizontal part of pipe C where it is pivoted at point E and continues along to point F. At point F the lever arm D comes into contact with the centre stem of the main bath, sink or basin plug When a bath, sink or basin is to be filled with water, the main Fug G will be inserted into it's respective hole. On pushing the plug G fitted with its centre stem down it will push the lever arm D downwards at point F.This action by use of pivot E will cause the other end to rise.

Consiquently lifting collecting B up the pipe .

The bath, sink or basin taps are then turned on, usually releasing a rapid flow of water into the bath, sink or basin.

If the taps are not turned off in time, the water level will rise, until it reaches the overflow outlet. Water will then start to flow down the overflow pipe A.

The flow of water down pipe A will be restricted by the collecting bucket B. If enough water is allowed to collect in pipe A the weight of water will cause collecting bucket B to push downwards. This will by means of lever arm D and pivot E push plug G upwards.

When plug G has been lifted, it will allow a fast flow of water out of the bath, sink, or basin, until the water level has fallen below the top of pipe A. When this has happened, no more water will run down pipe A. The water level in pipe A will then drop. When sufficiant weight of water has passed the collecting bucket B the weight of plug G will then be greater than that of bucket B, thus pushing bucket B upwards and closing the main outlet of the bath, sink or basin. This complete cycle will repeat until the taps are turned off.

Pipe C may be constructed of one or more parts to allow for access and cleaning, as may pipe A.

Letter H on drawing denotes sink, bath or basin.

Claims

1. An auto overflow comprising of an overflow tube, a collecting vessel to restrict the flow of water, a pivoted arm, a connecting rod to join arm to sanitary ware outlet sealer and water proof casing to house collecting vessel, pivoted arm and connecting rod.

2. An auto overflow as claimed in claim 1 where in an overflow tube has contained in it a moveable collecting vessel to restrict water flow passing down overflow tube.

Which is in contact by means to a pivoted arm.

3. An auto overflow as claimed in claim 1 and claim 2 where a pivoted arm is moved by a greater force being applied at one or other end is in contact by means to collecting vessel and connecting rod.

4. An auto overflow as claimed in claim 1 and claim 3 where in a moveable connecting rod is in contact by means with pivoted arm and sanitary ware outlet sealer.
