1, HOLDSWORTH ÅKEROYD, of 18, Marshfield Terrace, West Bowling,
Bradford, in the County of York, Contractor, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in water closets, and its object is to
prevent the basin, the cistern and the service pipe from being frozen and damaged
in frosty weather and also to economise water.
For this purpose the basin, cistern and service pipe are normally kept empty
and I introduce a valve in the supply pipe which is arranged to be automatically
opened by pressure upon the water closet seat so that as soon as pressure is applied
thereto by a person using the closet the said valve is opened and the flushing
cistern is more or less filled. The seat may be connected to the flushing valve or
its equivalent in such a manner that the flushing valve is opened and the basin is
automatically flushed and the cistern emptied as soon as the pressure is removed
from the seat and the supply valve in the service pipe is closed preferably by a
spring or weight. The parts may be operated automatically from a foot piece
arranged to be depressed when the closet is used or in any other convenient manner.
The trap for the basin is preferably not arranged immediately beneath the basin
but a suitable pipe or extension connects the bottom of the basin to a trap placed
sufficiently in the ground to prevent it being frozen in frosty weather.
To empty the supply pipe between the said valve and the cistern a second valve
may be introduced therein which is normally open and connects the supply pipe
with the pipe leading from the basin to the trap. This valve is arranged to be
automatically closed when the other valve is opened.
A two-way valve of suitable form may be used instead of two separate valves
and it is preferably fitted below the level of the ground to prevent it freezing.
Dated this 8th day of June 1895.

I, HOLDSWORTH A KEROYD, of 31, Greaves Street, Park Lane, Bradford, in the
County of York, late of 18, Marshfield Terrace, West Bowling, Bradford, aforesaid,
Contractor, 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 :--
This invention relates to improvements in water closets, and its object is to
prevent the basin, the cistern and the service pipe from being frozen and damaged
in frosty weather and also to economise water.
For this purpose the basin, cistern and service pipe are normally kept empty and
I introduce a valve or tap in the supply pipe which is arranged to be automatically
opened by pressure upon the water closet seat so that as soon as pressure is applied

page_text: thereto by a person using the closet the said valve is opened and the flushing cistern
is more or less filled. The seat may be connected to the flushing valve or its
equivalent in such a manner that the flushing valve is opened and the basin is
automatically flushed and the cistern emptied as soon as the pressure is removed
from the seat and the supply valve in the service pipe is closed preferably by a
spring or weight.
The trap for the basin is not arranged immediately beneath the basin but a
suitable pipe or extension connects the bottom of the basin to a trap placed
sufficiently in the ground to prevent it being frozen in frosty weather.
To empty the supply pipe between the said valve and the cistern a second valve
or tap may be introduced therein which is normally opened and connects the supply
pipe with the pipe leading from the basin to the trap. This valve is arranged to
be automatically closed when the other valve is opened.
A two-way valve or tap of suitable form is preferably used instead of two
separate valves and it is fitted below the level of the ground to prevent it freezing.
Reference is to be had to the accompanying sheet of drawings forming a part of
this specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents an elevation with the flushing cistern in section of a water
closet fitted with my improvements.
Figure 2, represents a side view of the same.
Figure 3, represents a sectional view on a larger scale of the two-way valve
I prefer to use.
The basin A and seat B are of any ordinary type excepting that the seat is
normally slightly raised by the weight C fixed to the rear end of the lever C 2
which is pivoted by the stud C 3 to one of the seat brackets B 2. The front end
of the lever 2 is connected to the fixing B 3 which bears against the underside of
the seat B and is connected by the rod C 5 to the valve spindle D of the two-way
valve E. The valve E has two valve seats E2 and E 3 fitted with valves E4
and E 5 both secured on the spindle D. The water supply pipe F is coupled to
the passage E 6 of the valve and the pipe G is coupled to the passage E7 of the
valve and connects the said valve with the flushing cistern J and it may be fitted
with a ball cock H. The flushing pipe J 2 connects the cistern J with the basin A
in the usual way excepting that the flushing valve J 3 is held normally open and is
suspended by the chain or its equivalent J 4 to the inner end of the lever J5
pivoted in bearings J 6, J 6 on the sides of the cistern; and the outer end of the
lever J 5 is connected by the chain J 7 to the rear end of the lever C2. The
bridge J 9 fixed across the cistern limits the motion of the lever J 5 and valve J 3.
When pressure is applied to the seat B it is depressed thereby lowering the front
end of the lever C 2 and at the same time presses down the valve spindle D so as
to open the valve E 4 and close the valve E 5 and allow the water to flow through
the passage E 7 up the pipe G and through the ball cock H into the cistern J until
the pressure on the seat B is removed or the cistern becoming full the ball cock
closes in the ordinary way. At the same time as the valve E4 is opened the rear
end of the lever C 2 is lifted which relieves the tension on the chain J 7 and allows
the valve J 3 to drop on to its seat and close the flushing pipe. But as soon as the
pressure is removed from the seat B the weight C again falls thereby closing the
valve E4 and also opening the flushing valve J 3 automatically flushes the basin..
In order to leave the cistern perfectly empty after the basin is flushed the
bottom J 8 of the cistern is inclined on all sides to the valve seat which is sunk.a
little way below the bottom J 8. And to avoid the usual raised seat it is formed of
a ring or washer O of india-rubber or other suitable material let into the metal
union 2 connected to the flush pipe J2. The under face of the valve J 3 is
recessed so as to leave an annular rim 03 to bear upon O and form a water tight
joint.
A plate P is secured to the union piece P 2 of the pipe F between the nuts P 3, P 3
secured upon said union piece. This plate is made to rest upon and is fixed to the

page_text: brick-work or bottom of the chamber K in which the valve is placed and which is
made sufficiently deep to prevent the water in the valve from being frozen. This
chamber is fitted with a lid through which the rod C 5 may pass.
When the valve E 4 is closed the valve E 5 is opened which allows the water to
escape from the pipe G through the passage e into the waste pipe e 2 coupled to the
pipe or extension piece A 2.
The trap A 3 is placed sufficiently below the surface of the ground to prevent
the frost reaching it in frosty weather and is connected to the basin A by the pipe
or extension piece A 2.
Other means may be employed to automatically operate the valves E4, E5
and J 3 instead of the arrangement shown.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performied, I declare that what
I claim is:
1. A water closet having a flushing cistern and a flushing valve of the form
shown which cistern and also the pipe supplying it are normally empty and are
arranged to be automatically filled by the user of the closet, substantially as herein
shown and described.
2. A water closet in which the flushing cistern and pipe supplying it are normally
empty and are arranged to be automatically filled by the user of the closet, in
combination with a basin the trap of which is below the reach of frost and a valve
or valves for automatically supplying the flushing cistern and for discharging the
contents of the pipe supplying the flushing cistern, substantially as herein shown
and described and illustrated in the accompanying drawings.
