Abstract

An overflow fitting for a siphon-discharge W.C. cistern comprises an outer pipe 10 and an inner pipe 9 smelted together to form a single pipe 5. When there is a malfunction in the cistern and the water level 7 rises above the holes 8, the overflow water runs between the outer pipe 10 and inner pipe 9 down into the toilet pan. When the flush system is operated, the flush water runs inside the inner pipe 9 down into the toilet pan. Both the overflow water and the flush water run into the toilet pan but they flow totally separate and do not interfere with each other. <IMAGE>

Description

COMBINED FLUSH A@@ OVERFLOW SYSTE@ This invention relates to @ overflow system.

An overflow system in a toilet is a simple system designed to carry water out of the building when there is a malfunction in the system of the toilet to stop flooding inside the building.

This product is designed to carry the overflow water directly into the toilet pan. It consists of a twin pipe system one smaller pipe inside a larger pipe which are smelted together to form a single pipe at the top but two seperate pipes where it enters into the toilet pan the inner pipe carries the water which flushes the toilet. The overflow water runs in the space between the internal and external pipes, both the overflow water and the flush water end up in the toilet pan bnt they flow totally seperete and do not interfear with each other.The overflow wnter enters four holes cut into the external pipe above the required water level.

Sheet 1-4 fig 1 shows an elevation of the overflow system combined with the flush system.

Sheet 2-4 fig 2 shows the internal pipe which carries the flush water shown in hidden detail on sheet 1-4.

Sheet 3-4 fig 3 shows a pLan of the combined overflow and flush system as seen through section A-A shown on sheet 1-4.

Sheet 4-4 fig 4 shows the conector required when the system is conected to the toilet pan via a pipe0 Referring to the drawing the overflow system comprises of an external pipe 10 and a smaller pine 9 which fits inside the larger pipe 10 which are smelted together to form a. single pipe 5 but there are two seperate pipes where it enters into the toilet pan 21. The inner pipe 9 carries the water which flushes tiie toilet.The overflow water runs in the space 11 between the internal pipe 9 and the external pipe 10. Both the overflow water and the flush water end up passing though the china section 14 and then entering the toilet pan 21 but they flow totaly seperate and do not interfear with each other The overflow water entars four holes 8 cut in the external pipe 10 above the required water level 7. An air trap 20 is fitted above the holes 8 pretruding below the water level 7 which stops any foul smels traveling from the toilet pan into the overflow system. A simple flush system 6 is also shown.

This system will fit 2 close couple toilet system but before it can be fited to the system where the cysten is connected to a toilet via a. pipe 19 an adapter sheet 4-4 fig. 4 is provided this consists of a nut head 17 smelted on to pipe 18. Pipe 19 is pushed and glued into pipe 18,

Claims

CLAIMS 1 This overflow system, comprises of a twin pipe system, one smaller pipe inside a larger pipe which are smelted together to forni a single pipe at the top, but two separate pipes where it enters into the toilet pan. The inner pipe carries the water which flushes the toilet The overflow water runs in the space between the internal and external pipes.

Both the overflow water STId the flush water end up in the toilet pan but they flow totally separate and do not interfear with each other.

The overflow water enters four holes cut into the external pipe above the required water level
2 The overflow system as claimed in claim 1 also comprises of a air trap to stop any foul smells travelling through the overflow system.
3 The overflow system as claimed in claim 1 and claim 2 can be operated in both a close couple system and a system where the toilet pan is atatched to a cysten via a pipe
