Improvements in Water Closet Apparatus.
I JOHN BENNETT COOK of 136 Horseferry Road Westminster in the County of
Middlesex Brass finisher do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide water closets with apparatus whereby the
usual bellows regulator and the weight on the water supply valve lever can be
dispensed with and thus the water closets are simplified and cheapened in
construction.
To carry out this object I use the ordinary valve to govern the supply of water the
spindle of which valve is raised by the usual lever but on the top of this valve casing
a corresponding casing is secured or formed wherein an ordinary recessed or bucket
valve stiffened if required by a plate is secured on the spindle and a passage governed
by a regulating tap passes up the walls of this casing one end of which passage
communicates with the water supply pipe while the other end opens into the casing
above the bucket valvo.
In its normal closed position therefore when the water supply valve is closed the
water has filled the bucket valve above through the passage whereby this condition is
maintained but when the water supply valve is lifted the water in the bucket valve is
forced back again through the passage and the flush is effected and when the lever of
the water supply valve released the water gradually fills the bucket valve until the
weight thereof closes the water supply valve.
On an arm secured on the spindle of the handle of the closet is mounted a disc by
a pivot passing therethrough near its periphery and a pin is secured near the periphery
of this disc preferably opposite to the aforesaid pivot or thereabouts. On the end of
the water supply valve lever is also a pin which passes through a concentric or
curved slot in another similar disc through which slot passes also the aforesaid pin
on the former disc.
The water supply valve lever the spindle of the handle the discs and the pins
passing through the slot in the one disc are all so arranged and formed that when the
handle has been raised to its full required extent the lever is also raised as the two
pins are at the opposite ends of the slot the pin connected with the spindle being
above the pin on the lever but when the handle is released and the spindle falls the
pin connected therewith is below the pin on the lever and this latter pin can therefore
allow the lever to descend by travelling along the slot until the two pins are close
together therein and the water supply valve is closed as before described.

Improvements in Water Closet Apparatus.
I JOHN BENNETT COOK of 136 Horseferry Road Westminster in the county of
Middlesex Brass finisher 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 :-
The object of this my invention is to provide water closets with apparatus by the
use of which the usual bellows regulator and the weight on the water supply valve
lever can be dispensed with and thus the water closets are simplified and cheapened
in construction and are not so liable to get out of order or become damaged by vermin
or insects or otherwise.

page_text: In order to explain my invention I refer to the accompanying drawing wherein I
have shewn my apparatus for carrying out the aforesaid object.
Figure 1 is a longitudinal vertical section of the water supply valve according to
this my invention.
An ordinary valve A is used to govern the supply of water to the closet the
spindle B whereof is raised as is customary by an ordinary lever C and the valve
casing D can be formed and made in the usual manner with the necessary seating for
the valve A which as is shewn is closed against the supply of water. On the top of
this valve casing D is secured or formed a corresponding casing E wherein on the
valve spindle B is secured an ordinary recessed or bucket valve F the bottom of which
can very conveniently be stiffened if desired by the plates G and G₁ above and below
the same and the lower plate can suitably be supported as is shewn by a shoulder
on the spindle B. A passage I is formed in the walls of these casings D and E one
end of which opens into the water supply pipe below the valve A while the other end
of this passage H opens into the casing above the bucket valve F and this passage H
is or may be governed by a suitable regulating tap or plug J.
All the parts of this compound valve are so proportioned and in particular the area
of the bucket valve F is so much larger than that of the valve A that in its normal
state the valve is in the position shewn in Figure 1 with the water supply closed as
the water bas filled the bucket valve F through the passage H whereby the valve A
is pressed and maintained tightly down on its seat. The valve A can be lifted from
its seat by the lever C through the spindle B when the water in and above the bucket
valve passes back again through the passage I into the water supply pipe being
assisted in such passage by the suction induced by the rush of water through this
supply pipe and the desired flush is effected and when the lever is released the
water again passes up the passage H into the bucket valve F and gradually fills the
same until the weight thereof closes the valve A and this compound valve is again in
its normal position shewn in Figure 1. The quantity of water allowed to pass up the
passage H and therefore the duration of the flush after the lever C has been released
is governed by the regulating tap or plug J if so fitted.
This compound valve so made as herein before described can conveniently be
supported by a standard K on the top whereof is formed a flange K through an
hole in which flange a screw bolt L formed with or secured to the bottom of the
valve casing D can pass and be secured in position by a nut.
Figures 2 and 3 are elevations of the apparatus by which this water supply valve
is actuated and through which the same is allowed to act.
An arm M is secured either on the ordinary spindle N of the handle N₁ of the
closet or as shewn on another spindle O jointed in a similar manner to the lever of
the valve of the closet on which arm M is mounted a disc Q by a pivot pin R passing
therethrough near its periphery and a stud S is secured on this disc Q also near its
periphery but preferably opposite to the pin R or thereabouts. On the end of the
water supply valve lever O is secured a stud T whereto is connected or whereon is
mounted another similar disc V in the following manner that is to say a concentric
or curved slot W is made in this disc V wherethrough the stud T loosely passes and
through this slot W also loosely passes the aforesaid stud S on the disc Q.
The water supply valve lever C the spindle N or O the arm M the discs and V
the slot W and the studs S and T are all so arranged and fitted and formed and
proportioned that when the handle N of the closet has been lifted to its full required
extent to open tho valve of the closet as is shown in Figure 2 the lever C is also
lifted the water supply valve is opened and the desired flush is effected as the two
studs S and T are at the opposite ends of the slot W the stud S on the disc con-
nected with the bandle being above the stud T on the lever C but when the
handle N' is released and allowed to fall to close the valve of the closet as is shewn in
Figure 3 the stud S on the disc Q connected therewith is below the stud T on the
lever C and it is sufficiently obvious that in this position no impediment will be offered
to the gradual closing of the water supply valve in manner as hereinbefore described
and the consequent descent of the lever as the stud T thereon plainly can travel along

page_text: the slot W or the slot W can travel on the stud S or both travels can be performed
together causing the discs Q and V to oscillate or move in manner as may be necessary
to permit such travel or travels.
I have hereinbefore described and I have shewn in the drawing this apparatus as
formed with discs to allow of the aforesaid actions which discs on the whole I consider
to be the most convenient and the best for many reasons but it is sufficiently obvious
and I would have it clearly understood that I do in no wise limit myself to the use of
discs for instead of either or both of the discs Q and V I may fit arms or links in a
similar manner that is to say if I fit a link in the place of the disc Q it would be
jointed to the arm M at one end while the other end would carry the stud S and
again if I fit a link in the place of the disc V it would be formed with the slot W
wherethrough both the studs S and T would loosely pass.
It is obvious also that this apparatus as hereinbefore described and shewn in
Figures 2 and 3 of the drawing can be used with any other similarly self-closing
water supply valve.
When desired also for the purpose of adapting this apparatus to water closets with
differing heights of lift of the handles thereof or of the water supply valves thereof
or with differing lengths of the water supply valve levers thereof or otherwise of
adapting the one pattern of this apparatus to different water closets the stud S as also
is necessary the pin R may be so secured in any usual or convenient manner in and
to the disc Q or the substituted link as to be adjustable whereby the distance
between the stud S and the pin R can bo varied as may be required in each
particular case.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a water supply valve the combination with a valve A on a spindle B and
actuated by a lever of a bucket valve F on the same spindle B and a passage H
leading from below the valve A to above the valve F and governed by a
tap or plug J substantially as and for the purpose hereinbefore described and
declared.
2. In a water supply valve the combination on a spindle B of the valves A and F
with a passage H leading from below the valve A to above the valve F substantially
as and for the purpose hereinbefore described and declared.
3. The combination in and between and with a water supply valve lever and a spindle
connected with and actuated by the handle of a closet of an arm M on this spindle a
link or disc Q connected to the arm M and having a stud S a stud T on the end of
this water supply valve lever and a link or disc V having a slot W wherethrough the
studs S and T loosely pass substantially as and for the purpose herein before described
and declared.
4. The water closet apparatus substantially as hereinbefore described and shewn in
