Year: 1872

page_text: LETTERS. PATENT to William Wright, of Sheffield, in the County of
York, Plumber, for the Invention of “IMPROVEMENTS IN APparatus
FOR PREVENTING THE WASTE OF WATER, APPLICABLE TO WATERCLOSETS AND
OTHER PURPOSES."
Sealed the 21st January 1873, and dated the 23rd November 1872.
PROVISIONAL SPECIFICATION left by the said William Wright at the
Office of the Commissioners of Patents, with his Petition, on the
23rd November 1872.
I, WILLIAM WRIGHT, of Sheffield, in the County of York, Plumber,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN APPARATUS FOR PREVENTING THE WASTE OF WATER, APPLICABLE TO WATER-
CLOSETS AND OTHER PURPOSES," to be as follows :—
My Invention consists of a moveable cistern working within another
cistern, the inner cistern having a valve at the bottom, the outer cistern
also having a valve at the bottom. When the apparatus is at rest the
inner cistern is filled with water by means of a ball tap, and the valve in
the said cistern is open while that in the outer cistern is closed. By
raising the inner cistern the valve at the bottom of it is closed before the

page_text: valve in the outer cistern is opened, and this valve in the outer cistern is
opened by the rising of the inner cistern, thereby allowing the water
contained in the outer cistern to pass through its valve and flush the
closet, at the same time closing the valve in the inner cistern. The
valves in both cisterns are opened and closed as required by the action
or movement of the inner cistern. The said valves are not connected
with any rod, wire, or chain, and are closed by their own gravity.
A
The above described apparatus may be applied to other purposes in
which it is desirable to prevent the waste of water or to measure the
quantities of liquids by duly regulating the size and capacity of the
outer cistern.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Wright in the Great Seal Patent Office on
the 21st May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WRIGHT, of Sheffield, in the County of York, Plumber, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of November, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Wright, Her special licence
that I, the said William Wright, my executors, administrators, and
assigns, or such others as I, the said William Wright, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR PREVENTING THE-WASTE OF WATER, APPLICABLE TO WATERCLOSETS
AND OTHER PURPOSES," upon the condition (amongst others) that I, the
'said William Wright, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to

page_text: be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Wright, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to
say) :-
My Invention of "Improvements in Apparatus for Preventing the
Waste of Water, Applicable to Waterclosets and other Purposes,"
consists of a moveable cistern working within another cistern, the inner
cistern having a valve at the bottom, the outer cistern also having a
valve at the bottom. When the apparatus is at rest the inner cistern is
filled with water by means of a ball tap, and the valve in the said cistern
is open, while that in the outer cistern is closed. By raising the inner
cistern the valve at the bottom of it is closed before the valve in the
outer cistern is opened, and this valve in the outer cistern is opened by
the rising of the inner cistern, thereby allowing the water contained in
the outer cistern to pass through its valve and flush the closet, at the
same time closing the valve in the inner cistern. The valves in both
cisterns are opened and closed as required by the action or movement of
the inner cistern. The said valves are not connected with any rod,
wire, or chain, and are closed by their own gravity.
The above described apparatus may be applied to other purposes in
which it is desirable to prevent the waste of water or to measure the
quantities of liquids by duly regulating the size and capacity of the
outer cistern.
Having thus stated the nature of the said Invention I will proceed to
describe more particularly in what manner the same is to be performed
by the aid of the accompanying Drawings in which are represented two
different forms of valves for working the apparatus referred to.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are a vertical section and plan or horizontal view

page_text: A is the outer cistern or "boot" which is adapted to contain any
required quantity of water to flush the closet; B is the valve at the
bottom of this cistern through which the water escapes to the closet
when the valve is opened. This valve as shewn at Fig. 1 is raised in
order to open it by the rising of the cistern D through its connection 5
with the air pipe C, and is allowed to become closed by its own gravity
on the descent of the cistern D. The cistern D is suspended at one end
on a cross shaft E mounted in bearings at the top of the cistern A by
means of a jointed arm F, and at the opposite end by two pivots G, G,
fixed to the interior of the outer cistern. The inner cistern D is raised 1
as required by pressure being applied to the lever H through its con-
nection with the seat or otherwise. I is the ball tap by means of which
water is admitted to the cistern D. In the bottom of this cistern is
fitted a valve K which is closed by its own gravity on the rising of the
cistern D, and opened by the descent of the same causing its stem to 1
come in contact with a step L on the bottom of the cistern A, the
further descent of the cistern D then lowers the seat from the valve K'and
opens the valve.
In Fig. 3 the valves B and K are shown as being on the same stem,
on which slides a collar M fixed into the bottom of the cistern D. By 2
this arrangement the raising and lowering of the cistern D opens and
closes the two valves B and K. as required.
The action of the apparatus is as follows:-When the apparatus is at
rest the inner cistern D is filled with water by means of the ball tap I,
and the valve K is open while the valve B is closed, the cistern D being a
lowered. On pressure being applied to the lever H the cistern D is
raised, and the valve K is closed before the valve B is opened, but the
valve B is opened by the further rising of the cistern D (as shewn in
Fig. 1), thereby allowing the water contained in the outer cistern A to pass
through the open valve B and flush the closet. On the pressure being a
removed from the lever H the cistern D is allowed to descend, thereby
closing the valve B and opening the valve K, when the water admitted
into the cistern D will pass into the cistern A and remain there until it
is again discharged through the valve B on the raising of the cistern D.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that what I claim
as of my Invention is, the combination of a moveable cistern working

page_text: in the manner described within an outer cistern of suitably capacity to
contain the quantity of water to be discharged or measured at each
action of the apparatus, with valves adapted to be opened and closed by
the action of the movable cistern, and by their own gravity in the
manner described.
In witness whereof, I, the said William Wright, have hereunto set
my hand and seal, the Twentieth day of May, in the year of our
Lord One thousand eight hundred and seventy-three.
