page_text: the
LETTERS PATENT to Henry Charles Attwater, of Horsham, in
County of Sussex, for the Invention of "AN IMPROVED SUPPLY AND
STOP VALVE.”
PROVISIONAL SPECIFICATION left by the said Henry Charles
Attwater at the Office of the Commissioners of Patents, with his
Petition, on the 15th February 1878.
I, HENRY CHARLES ATTWATER, of Horsham, in the County of Sussex,
do hereby declare the nature of the said Invention for "AN IMPROVED
SUPPLY. AND STOP VALVE," to be as follows:-
According to my Invention I construct my improved supply and stop
valve with an upper and lower chamber, each containing a valve, the
object of the upper valve being to close and shut off the water when-
ever the lower one is removed in order to renew the leather or other
facing for repairs or other purposes, thus preventing any waste of water
or trouble in stopping it; and the object of the lower valve being. to

page_text: close and shut off the water when the cistern it is intended. to supply is
full.
The upper chamber contains near its lower extremity an annular valve
seat, upon which a ball forming the upper valve falls, to close the
passage when the spindle of the lower valve is withdrawn, and from the
upper part of this chamber proceeds a short horizontal pipe to screw into
and connect it with the service pipe.
The lower chamber, part of which forms the outlet or nozle, screws on
to the lower part of the upper chamber and contains the lower valve,
which closes against an appropriate annular seat and is fixed on a
spindle which passes through its centre, and extending upwards holds
the upper valve open as long as the lower one is in its place, and extends
downwards through the nozle at the bottom of the lower chamber, under
the centre of which it is jointed to a horizontal vibrating lever which is
attached by a joint to one side of the nozle, the other end carrying the
usual hollow metal ball, operated upon by the water in the cistern.
The lever passes through and works in a guide attached to the nozle on
the side opposite to that on which the lever is attached, and a pin passed
horizontally through the guide supports the lever when the water in the
cistern is low, and thus prevents the ball falling below a certain point.
By using a washer of the right thickness in the screw joint between the
upper and lower chambers, the ball may be set in whatever direction is
most convenient.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Charles Attwater in the Great Seal Patent 2
Office on the 14th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
CHARLES ATTWATER, of Horsham, in the County of Sussex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Fifteenth day of February, in the .year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Charles Attwater, Her special

page_text: licence that I, the said Henry Charles Attwater, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Charles Attwater,
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
"AN IMPROVED SUPPLY AND STOP VALVE," upon the condition (amongst
others) that I, the said Henry Charles Attwater, 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 dato
of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Charles Attwater, 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 thereof, reference being had to the accom-
panying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say :-
According to my Invention I construct my improved supply and stop
valve with an upper and lower chamber, each containing a valve, the
object of the upper valve being to close and shut off the water whenever
the lower one is removed in order to renew the leather or other facing
for repairs or other purposes, thus preventing any waste of water or
trouble in stopping it, and the object of the lower valve being to close
and shut off the water when the cistern it is intended to supply is full.
The upper chamber contains near its lower extremity an annular valve
scat, upon which a ball forming the upper valve falls to close the
passage when the rod or stem carrying the lower valve is withdrawn,
and from the upper part of this chamber proceeds a short horizontal pipe
to screw into and connect it with the service pipe.
The lower chamber, part of which forms the outlet or nozle, screws on
to the lower part of the upper chamber and contains the lower valve,
which closes against an appropriate annular seat and is fixed on a rod or
stem which passes through its centre, and extending upwards holds the

page_text: upper valve open as long as the lower one is in its place, and extends
downwards through the nozle at the bottom of the lower chamber, under
the centre of which it is jointed to a horizontal vibrating lever which is
attached by a joint to one side of the noźle, the other end carrying the
usual hollow metal ball float operated upon by the water in the cistern.
The lever works in a guide attached to the nozle at the side opposite to
that on which the lever is attached, and a pin passed horizontally
through the guide supports the lever when the water in the cistern is
low, and thus prevents the ball falling below a certain point. By using
a washer of appropriate thickness in the screw joint between the upper 1
and lower chambers the ball may be set in whatever direction is most
convenient.
And in order that the said Invention may be fully understood, I
shall now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the Sheet of Drawings 1
hereunto annexed. The same letters of reference indicate corresponding
parts throughout all the Figures.
Figures 1 and 2 of the Drawings represent valves constructed accord-
ing to my said Invention; Figures 3 and 4 represent longitudinal
vertical sections of 1 and 2 respectively.
A is a horizontal pipe and screw for connection with the service
pipe; B is the upper chamber with the annular valve seat O and the
ball valve D; E is a small bar with an eye in its centre, which acts
as a guide for the rod or stem F; G is the lower chamber attached
by the screw H to the upper chamber; I is a disk valve with facing
of vulcanized india-rubber or other suitable material, which is retained
in its place by the disk of metal screwed down on it on the rod or
stem F, which extends upwards into the upper chamber, and down-
wards to form the joint K, with the vibrating lever or arm L imme-
diately under the nozle. The arm L is jointed to one side of the nozle
at M and at the free extremity carries the usual hollow metal ball
float. O is a guide in which the arm or lever L works, and by a pin
through which the said lever carrying the ball float is prevented from
falling below the point shown in the Drawings. A small bar across the
upper part of the upper chamber prevents the escape of the ball forming
the upper valve into the service pipe. The valve I is opened and closed
by the falling or rising of the water in the cistern acting on the float

page_text: ball. The valve D is held open by the rod or stem F so long as the
lower valve remains in its place, but when that is removed for repairs or
otherwise the rod or stem F being withdrawn the valve D closes on to
the seat C.
Having now fully described and set forth the nature of my said
Invention together with the best means I am acquainted with of
carrying the same into practical effect, I would observe that what I
consider novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the general
construction and arrangement, substantially as herein described and
shewn in the Drawing annexed.
In witness whereof, I, the said Henry Charles Attwater, have
hereunto set my hand and seal, this Thirteenth day of August,
in the year of our Lord One thousand eight hundred and seventy-
three.
