Improvements in Water Closets, and in Apparatus suitable for
Flushing the same.
We, SIDNEY JENNINGS and JOHN MORLEY. both of Palace Wharf, Stangate,
Lambeth in the County of Surrey, Sanitary Engineers, do hereby declare the
Dature of this invention to be as follows:-
any suitable way
Water is slowly admitted into an automatic flushing tank in
preferably through a small hole in the supply pipe the size of which is regulated
by a screw. There is a ball valve preferably a balanced valve on the supply pipe
which admits water not to the tank but to the upper end of the long leg of the
syphon leading from it whose lower end is trapped. The ball or float is in a

is emptied by a small syphon whose long leg leads into the main tank. Should an
after flush be required the short leg of the main syphon does not reach to the
bottom of the main tank so that the latter is not completely emptied by it the
remaining water being used as an after flush and being delivered by a small syphon
whose long leg passes a short way down the delivery pipe.
The Specification of a Patent No. 5940 of 1883 describes starting the syphonic
action to empty the closet pan by causing the descent of the water to the pan to
suck out the air from the closet trap. According to this invention the arrange-
ment is simplified the top of the air pipe from the closet trap being simply bent
over and led a ehort way down the delivery pipe from the flushing tank.
In closets which are also intended to be used as urinals we provide a back of
earthenware rising up from the pan and preferably made in one piece with it. The
seat turns up against this back and in place of being made in the form of a
complete ring is U shaped the pivots being at the ends of the sides of the U.
The closet therefore forms a complete urinal with a back and there is little chance
of the floor or seat being wetted.

, COMPLETE SPECIFICATION.
Improvements in Water Closets, and in Apparatus suitable for
Flushing the same.
We, SIDNEY JENNINGS, and JOHN MORLEY, both of Palace Wharf, Stangate,
Lambeth, in the County of Surrey, Sanitary Engineers, do hereby declare the
nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
Figure 1 is a vertical section of a closet and flushing tank constructed according

page_text: to this invention and Figure 2 is a vertical section of the flushing tank to a
larger scale.
e
Water is slowly admitted into an automatic flushing tank a in any suitable way
preferably through a small hole.b (Figure 2) in the supply pipe the size of which
is regulated by a screw c. There is a ball valve preferably a double seated
balanced valve d with two outlets on the supply pipe actuated by the lever e¹ and
ball which admits water to the tank a and also to the pipe leading to the upper
end of the long leg g of the syphon leading from it whose lower end is trapped
at h. The ball or float e is in a separate compartment a' inside the main tank a..
When the main tank has been filled by the small hole the water flows over the
edge a² of the ball compartment and slightly raising the ball partially opens the
ball valve d admitting an increasing flow of water into the tank a which over-
flowing into the compartment a rapidly fills it raising the ball its full height and
completely opening the valve d. This causes a jet of water to flow down the
syphon thus starting it and emptying the tank. The ball compartment is emptied
by a small syphon whose long leg leads into the inain tank. Should an after flush
be required the short leg g' of the main syphon does not reach to the bottom of the
main tank a so that the latter is not completely emptied by it the remaining water
being used as an after flush and being delivered by a small syphon k whose long
leg passes a short way down the delivery pipe l.
The Specification of a Patent No. 5940 of 1883 describes starting the syphonic
action to empty the closet pan by causing the descent of the water to the pan to
suck out the air from the closet trap. According to this invention the arrangement
is simplified the top of the air pipe m from the closet trap n being simply bent over
and led a short way down the delivery pipe 1 from the flushing tank a.
In closets which are also intended to be used as urinals we provide a back.o of
earthenware rising up from the pan and preferably made in one piece with it. The
seat p turns up against this back and in place of being made in the form of a
complete ring is Ŭ shaped the pivots being at the ends of the sides of the U. The
closet therefore forms a complete urinal with a back and there is little chance of
the floor or seat being wetted.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:―
1. An automatic flushing tank which is gradually filled and then emptied by a
syphon started by a jet of water turned on by the motion of a float in a com-
partment separate from the main tank and filled by the overflow from it.
2. An automatic flushing tank (with or without the parts k and m) substantially
as described and shown in the drawings.
3. Leading the air pipe from the closet trap into the top of the delivery pipe
from the flushing tank.
4. The combination of an earthenware back rising up from the pan with a
U shaped seat.
