"
PROVISIONAL SPECIFICATION left by the said William Wright at the
Office of the Commissioners of Patents, with his Petition, on the
5th April 1872.
I, WILLIAM WRIGHT, of Sheffield, in the County of York, Plumber,
3 do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN VALVES AND APPARATUS FOR FLUSHING WATERCLOSETS, AND OTHER PURPOSES,"
to be as follows:
In one arrangement I have two valves on one spindle, one to shut
upwards and the other downwards on a tube connected with a boot or
vessel to contain the necessary quantity of water. When the closet is
being used the top valve is opened and the bottom valve closed by the
action of the seat so as to admit of the water passing into the receiving"

page_text: vessel or boot. On the removal of pressure from the seat the valves fall
into their normal position, shutting off the water in the cistern and
allowing the water to flow from the boot into the closet.
The alternative arrangement I adopt is to substitute for valves a double
piston on a spindle, to act in a bored tube above and below the mouth
or inlet to the boot, in such a manner as to allow the water to flow into
the boot when the seat is depressed, and on the pressure being removed
to shut it off and allow the water from the boot to. flush the closet.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Wright in the Great Seal Patent Office on
the 3rd October 1872.
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 Fifth day of April, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
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 VALVES AND APPARATUS
FOR FLUSHING 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 be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.

page_text: 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 Valves and Apparatus for Flushing
Waterclosets and other Purposes" consists in the arrangements of valves
and pistons, herein-after described, for regulating the supply of water
from the cistern to the closet.
When the closet is
In one arrangement there are two valves on one spindle, one to shut
upwards and the other downwards in a tube connected with a
"boot" or
vessel to contain the necessary quantity of water.
being used, the top valve is opened and the bottom valve closed by the
action of the seat, so as to admit of the water passing into the receiving
vessel or "boot." On the removal of pressure from the seat the valves
fall into their normal position, shutting off the water in the cistern, and
allowing the water to flow from the "boot" into the closet.
In another arrangement, instead of the valves there is a double or
single piston on a spindle (which spindle consists of a tube acting as an
air pipe when the piston is at the bottom), to act in a bored tube above
and below the mouth or inlet of the "boot" in such a manner as to
allow the water to flow into the "boot" when the seat is depressed, and
on the pressure being removed therefrom to shut it off, and allow the
water from the "boot" to flush the closet.
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 the
arrangements of apparatus above referred to.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a section showing the arrangement of two valves on one
spindle; Fig. 2 shews the arrangement with a double piston; and Fig. 3
shews a single pistion for the same purpose. In these several Figures
the same letters of reference indicate corresponding parts.
In Fig. 1, A is the spindle on which are fitted two valves, the one of
which B shutting downwards on the top of the tube C, and the other

page_text: valve D shutting upwards a little below the mouth or inlet to the "boot"
through the pipe E. In this Figure the valves are shewn in such
positions as to allow of the water passing from the cistern to the " boot."
At this time the pressure on the seat has raised the spindle A, and with
it the two valves B and D, thereby closing the valve D by bringing it
upwards against its seat at F, and opening the valve B by raising it off
its seat at the top of the tube C, thereby allowing water to pass from
the cistern down the tube C and through the pipe E into the receiving
vessel or "boot."
When the pressure on the seat is removed, the spindle and valves
return into their normal positions, thereby lowering the spindle A. and
bringing the valve B down on to the top of the tube C, which it closes,
and carrying the valve D down below its seat F, thereby opening the
valve D and allowing the water contained in the "boot" to pass down
through the pipes E and G, and flush the closet.
In Fig. 2, H¹, H², is a double piston fitted on the spindle A, the
part H³ extending above the mouth or inlet to the "boot,” and the
part H being below the same. The part H' has an aperture I formed
in it, which leads into the said mouth or inlet, and through which water
passing from the cistern down the tube C can enter the "boot" through
the pipe E when the parts are in the positions shewn in the Figure, that
is to say, when the closet is in use and the seat depressed. But when
the pressure is removed from the seat the spindle A is raised, thereby
carrying the double piston upwards and closing the communication of
the tube C with the pipe E, and opening that between the pipes E and G,
through which the water will pass from the "boot" and flush the closet.
The spindle A being hollow acts as an air pipe when the piston is at
the bottom.
In Fig. 3 is represented a single piston valve H, elongated so as to
admit of its being caused to open and close the communications between
the cistern and the "boot," and the latter with the closet as required,
in the same manner as above described, by means of the double piston.
In the Figure the valve piston H is shown, with the communication
open from the cistern to the "boot" through the valve mouth I, but
when the spindle A is raised the valve piston is carried up so as to close
the pipe C and open the communication from the "boot" to the closet.

page_text: 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,
First. The arrangement of valves, represented in Fig: 1, and described.
And, secondly, the arrangement of double and single pistons, repre-
sented in Figures 2 and 3, and described.
In witness whereof, I, the said William Wright, have hereunto
set my hand and seal, the Twenty-seventh day of September,
in the year of our Lord One thousand eight hundred and seventy
two.
