Surrey, do hereby declare the nature of this invention to be as follows:-
The present invention, which may be employed in connection with closets of the
type known as valve closets, relates to means for delivering a regulated amount of
water for flushing purposes, and has for its main object the prevention of waste of

water, but it is also designed to ensure a proper flush of water while the
and an after flush when it is closed.
In closets hitherto constructed, small siphon tanks and other regulating arrange-
ments have been employed to prevent waste of water, but with most of these it is
possible, by propping up or fixing the operating handle, to keep open the water
supply valve and the pan valve, and thus create a continuous flow of water.
According to my invention, I dispense with regulating tanks, and fix the water
supply valve in the house water main or other pipe, and 1 prevent waste in the
following manner :-
The pan valve is actuated by a weighted lever in the ordinary way, so that the
raising of the lever opens the valve, and the falling closes the same.--Between this
weighted lever and the operating handle, I interpose mechanism which will raise the
lever to the required extent to open the valve, and then release it and allow it to fall,
notwithstanding the handle is still held up.-The lever is then locked by a suitably
placed pawl until the after flush is completed and the supply valve closed.

supply valve lever and the valve spindle, I place an additional weighted lever for
locking the valve by means of a pin upon the valve spindle working in a peculiarly
shaped slot in the lever head.
The locking lever is operated by the ordinary weighted lever through a link and
pin, but is so arranged that it cannot release the valve spindle until the pan valve

page_text: lever mechanism is about to release the lever and allow the pan valve to close.
The
flush of water is therefore delivered into an empty pan, which is closed before the
delivery ceases, and thus permits of an ample after flush.
The mechanism for lifting and releasing the pan valve lever consists of a long
slotted link having in the side of the slot, about the middle of its length a notch
wherein beds a pin fixed upon the pan valve lever. Pivotted upon the link near the
notch, is a cranked lever, which, its end being tripped as the handle reaches the
proper height, forces the notch of the link clear of the pin, and allows the pan
valve lever to fall and close the pan valve.
The handle can then be moved up and down without affecting the pan valve lever
as the notch is closed by the cranked lever, until the handle is put quite down, and
the end of the lever is again tripped in the opposite direction. When this takes place,
the handle is again in gear with the pan valve lever, and it is impossible to move it
until the pawl retaining such lever is forced out of action. This does not happen
until, the after flush being over, the lever actuating the supply valve descends, and
with a projecting arm forces back the retaining pawl, and thus puts the closet in a
condition for further use.

page_text: I WILLIAM HENRY STEIL, R.N., of 493 Battersea Park Road in the County of
Surrey, 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 present invention, which may be employed in connection with closets of the
type known as valve closets, relates to means for delivering a regulated amount of
water for flushing purposes, and has for its main object the prevention of waste, but
it is also designed to ensure a proper flush of water while the pan is open, and an
after flush when it is closed.
With closets as hitherto constructed, small syphon tanks and other regulating arrange-
ments have usually been employed to prevent waste, but with most of these it is
possible, by propping up or fixing the operating handle, to keep open the water
supply valve and the pan valve, and thus create a continuous flow of water.
According to my invention, I dispense with regulating tanks, and fix the water
supply valve in the house main or other pipe, and I prevent waste in the manner
hereinafter described.
The pan valve is actuated by a weighted lever in the ordinary way, so that the
raising of the lever opens the valve, and the falling closes the same. Instead, however,
of operating the water supply valve lever from the pan valve lever direct in the
ordinary manner, I introduce mechanism between them, which, after lifting the water
supply valve lever to the required height, becomes disconnected therefrom, and allows
it to fall, notwithstanding the operating handle is held up until the regulated quantity
of water has passed and the supply valve has again closed.
In the accompanying drawings,
Fig. 1 is a side view of a valve closet embodying my invention.
Fig. 2 is an end view thereof, and
Fig. 3 is a front view of the water supply valve detached.
A is the closet basin or pan supported on a suitable metal base, and provided with
a valve and discharge box in the usual manner. B is a weighted lever for opening
and closing the pan valve, being pivotted at its extremity furthest from the weight,
and operating the valve in a manner that is well understood.
The free end of the lever B passes between guides bb, in which slides the block b
attached to the end of the lifting handle B*, which is suitably mounted in the framing
of the closet. The block is connected to the lever B by the link 62 pivotted to both,
which enables the lever B to be raised or lowered, and the pan valve opened or closed
at pleasure.
Cis the water supply pipe in which is situated the water supply valve c.-D is a
weighted lever pivotted to the framing, and passing over and pressing upon the head
of the valve spindle c¹ of the valve c.- -E is a pneumatic contrivance or dashpot of
ordinary construction for retarding the descent of the lever D upon the head of the
valve spindle c¹.
The lever D is situated at right angles to the lever B before mentioned, and is
operated thereby through the weighted cranked lever a. The lever B is bifurcated
for part of its length, and within the divided part is pivotted the weighted cranked

page_text: lever
a,
the nose of which underlies the weighted lever D, and is so arranged that it
cannot tip forward as it strikes against it.-The tail of this lever a is supported by the
standard a passing thro' the bifurcated lever B.-The water supply valve is
opened by the water pressure to deliver its flush, but remains closed and locked until,
by the locking device shewn best in Fig. 3, a pin 63 upon the block of the handle B*
rises, and lifts a weighted lever F pivotted to a lug upon one of the guides b, and
linked to the locking device -The locking device consists of a pair of slotted
plates pivotted below to the valve casting, and connected together above by a rod or
bolt which is connected by a rod to the lever F.
The slots of the plates above mentioned are of peculiar form, being such as to
permit, when the plates are in one position, horizontal pins attached to either side of
the head of the valve spindle c¹ to rise with the valve spindle in a vertical direction,
and, when the said plates are in another position (drawn forward by the lever F), to
wedge down the pins, and force the spindle c¹ down upon its seat.
The action of the apparatus is as follows:
The handle B is raised, lifting the lever B to its dotted position, and opening the
pan valve. At the same time, the cranked lever a strikes against the underside of the
lever D, and lifts it to its dotted position (see Fig. 2).-This movement of the handle
opens the pan valve, and removes the weight of the lever D from the head of the
spindle c¹ of the water supply valve, hut the valve still remains closed until the
pin upon the block tips up the lever F, and throws the same and the locking
device into their dotted positions (see Fig. 2). This permits the valve c' to open;
the flush of water then follows, but meanwhile the nose of the lever a, moving in
an arc, has cleared the lever D, which commences to descend upon the valve
spindle, retarded in its downward course by the dash pot E. The nose of the lever a
being free of its load, the weighted tail falls, and lifts the nose out of the path
of the descending lever D, into which it cannot return until the stop a¹ comes in
contact again with the weighted tail. The lever D therefore continues to descend
until the water valve is closed, and the locking of the spindle is effected by the
locking device, operated by the weighted lever F.
It will thus be seen that only a predetermined amount of water, dependent upon
the speed of the descent of the lever D, which is regulated by the dash pot, can
be delivered each time the closet is used, and further, it will be noticed that as
the unlocking of the water supply valve is not effected until the pan valve lever
is raised to nearly its fullest height, the pan valve is opened, and the pan emptied
before the cleansing flush is delivered. This however can be readily adjusted according
to requirements by the position of the pin upon the block 61, or by the bend of
the unlocking lever F.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. For regulating the flush of water in closets, the employment of a disconnecting
device between the pan valve lever and the water supply valve, in the manner shewn
and described, for preventing the waste of water by retaining the supply valve
lever in a raised position.
2. The locking device for the water supply valve arranged and operating substan-
tially as shewn and described.
