at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 20th January 1873, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE FRESENTS SHALL COME, I, JAMES
GEORGE STIDDER, of 50, Southwark Bridge Road, Borough, in the
County of Surrey, Sanitary Engineer, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS `IN
APPARATUS FOR DRAWING AND PREVENTING WASTE OF WATER FROM Pipes, Mains,
CISTERNS, AND OTHER SOURCES, ALSO BALL AND SUPPLY VALVES FOR DOMESTIC AND

page_text: OTHER PURPOSES," and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that I am the truc
and first Inventor thereof.
NOW KNOW YE, that I, the said James George Stidder, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed in and by the following
statement and accompanying Drawings, that is to say :-
Sheet No. 1, Fig. 1, is a vertical section of a water waste preventer
for flushing water closets, urinals, &c. The external box (or case)
marked A, A, A, is a receptacle for water. The water is admitted
through the valve B, B, and escapes through the valve C and down the
pipe D at the same time filling the chamber E through the aperture
F, F, this chamber then dribbles out the water through the small hole G
and down the pipe D into the closet, thus allowing a certain quantity of
water to remain in the closet after its discharge. The division plate H
is laid in from the top and rests on an internal flange I, I, it is bedded
down with cement and kept secure by the keys J on the one end and
the valve C at the other end. The chamber X being now charged with
water the valves B and C are shut off by pulling down the lever K
working on a fulcrum Kº, the weight L rises and causes the cam
working on joint L^ to throw back the other end of the lever N on to
the ball valve lever O working from joint OB, the spindle P working from
the joint P rises up from → before the valve C is allowed to open.
By continuing to pull the lever K the valve C rises and the roller Q
rolls up the cam R", and by this motion the water is discharged out of
the large chamber X through the valve C into the closet or urinal, as
the case may be on the return motion the valve C falls into its place,
thus stopping any water from flowing out, the roller Q falls into the
bottom of cam M which raises the other end N, the float P drops down,
the valve T then rises, the water rushes down as shown by the arrows
into the chamber X, as the water raises the float S the valve closes on
its seat and shuts off the water from the chamber X and then remains
ready for the next discharge, as in no case can more than one valve be
opened at the same time; the regulating screw V is for tightening or
slackening the closet wires which are under the control of the person
fixing the work; the dotted lines W shew a small air pipe to carry off
the air from chamber E to facilitate the rush of water into the closet, &c.

valve.
The action is as follows:-The valve is now shut off, by pressing down
the knob A working through the stuffing box A* opens the valve B
from the seat C, the water then rushes out through the nose of valve
as shewn by the arrows; the double chamber D, D, is fixed into the
bottom of the valve E, E, the water passes through the small holes F, F,
as indicated by the arrows; on the bottom of spindle H is fixed a bucket
leather I (or a packed piston); when the valve B is open the pressure
of water acts against the bucket or piston allowing the valve B to go
gradually up to its seat C, stopping all concussion in the pipes; it works
freely under any pressure. J, J, is a flexible tube placed over the
spindle H, so that the water can pass out of the vacuum chamber at
back of bucket leather through the small hole dotted in centre of spindle
and into the chamber G whilst the valve is in action; K, K, shews a
spring for closing the valve when the pressure is taken off the knob A.
Fig. 3 is a vertical section of a high pressure lavatory or urinal water
valve, the internal arrangement is precisely the same as Fig. 2 with the
exception of the inner case A, A, coming away from the front and
bringing with it the interior part of the valve to facilitate repairs, the
valvo works horizontally instead of perpendicular, the socket A, A, is
to fit over the supply arm of an urinal, the pipe B passes on the inside
of the same arm, so as to make a complete cement joint, the dotted
lines C, C, shew a bib nose leading to a lavatory basin.
Fig. 4 is a vertical section, and Fig. 5 the plan of a treble lever
compound hall valve, the valve is now shut off. A, A, is the first lever
with ball connected at one end, the other end is fastened with a pin to
the two lugs on B, B, B, the second lever is C, C, C, working in a double
joint D, D, D, the third lever E, E, working in the two lugs F, F, F, the
end of lever E presses against the valve G, and shuts off the water at the
seat H, H, the inlet for water will be as the arrows denote, J, J, J, are
the cross lugs for working the other two levers C and E and valve G.
•
Fig. 6 is a vertical section of a double union connection, A the inlet, the
bent union B works in a stuffing box C with a flange D on the face side,
and a jamb nut E on the back side, the socket F, F, is made to fit the
outside of supply arm of the urinal, the internal piece G is made to
pass down the inside of supply arm so as to ensure a good sound coment-

position.
Having now particularly described and ascertained the nature of the
said Invention, and in what manner the same is to be performed, I
hereby declare that I claim the Invention of improvements in apparatus
for drawing and preventing waste of water from pipos, mains, cisterns,
and other sources, also ball and supply valves for domestic and other
purposes, as herein-before set forth and described and illustrated by the
Drawings hereto annexed, it being understood that I do not claim the
constituent parts herein referred to when taken per se and apart from
the purposes of my said Invention, and I have to remark that the
following are important parts of the several arrangements described in
these Presents.
Sheet 1, Fig. 1; is a water waste preventer for supplying closets,
urinals, lavatorics, &c., it will only give the quantity of water required
for each time using. By pulling down the lever the cam acts upon
the end of the ball valve so that no water can flow into the cistern
during the time the discharge valve is out of its seat, and the discharge.
valve doos not rise until the slack wire (or pin) reaches the under
side of the seat of valve weight, on the return motion the lower
discharge valve comes home before the cam leaves the end of ball lever,
after this the ball is left perfectly free and shuts off the valve as the
water raises the ball, the discharge valve seat passes through from the
partition out at the bottom, and forms a receptacle for the after charge.
I do not claim the weeping hole, or the air pipe leading from the after
charge, as this dribble hole was used many years back in the old-
fashioned service boxes for supplying closets.
Fig. 2 is a high pressure supply valve for lavatories, urinals, &c.,
it will work under any pressure, the water passes in from the bottom
through the holes in side of plunger box (or case) and into the large
chamber, and surrounds the bucket leather and under side of valve seat,
by pressing on the knob the water flows out of the hib, and the pressure
on the plunger below causes the valve to shut gontly, and stops the
concussion in the pipes, there is a small hole in the bottom of lower end
of spindle to allow the water to pass out of the vacuum chamber and
the piece of flexible tube stops more water from flowing in, the top
spindle passes through a stuffing box and is surrounded with a coil
spring.

page_text: Fig. 3 is a valve made upon the same principle for urinals, &c., only
the interior front chamber and scat all pull away from the front when
the nut is unscrewed, as seen in Drawing; this arrangement prevents
any breaking of joints. The dotted lines show another form of valve
suitable for lavatorics.
Figs. 4 and 5 are a treble compound ball valve working with three
levers, the last lever working against the shutting-off valve, the water
passes in as shewn on Drawing by the arrows, when the cistern is empty
the ball drops down and allows the valve to open, and then the rush of
water passes into the cistern, I do not confine myself to the shape or
working of the levers so long as I maintain the principle of the treble
compound action.
Fig. 6 is a double union connection for urinals, &c. with stuffing box
and socket, it will be readily seen that the urinals can be taken down for
repairs without disturbing any of the slate work to get at the back
joints, this I claim as an advantage over all other urinal joints.
In witness whercof, I, the said James George Stidder, have here-
unto set my hand and scal, this Twentieth day of January,
in the year of our Lord One thousand eight hundred and seventy-
thirec.
