PROVISIONAL SPECIFICATION.
Improvements in the Construction of Ball Valves.
We, ANDREW GIFFORD SOUTTER of 9, Bury Street, E.C. and WILLIAM
COTTRELL, 9, Bury Street, E.C., Sanitary Engineers, do hereby declare that we
are in possession of an invention for IMPROVEMENTS IN THE CONSTRUCTION
OF BALL VALVES, and that we are the true and first inventors thereof, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improvement in the construction of ball valves, and
the object sought to be attained is, that, first, the cistern, waste preventer, or other
receptacle can be filled noiselessly. Secondly, that one or more cisterns, waste
preventer or other receptacle can be filled by the one and same valve, and thirdly,
the one and same valve can be used both for filling the cistern, waste preventer or
other receptacle, and giving an afterflush to the water closet or other apparatus.
The valve consists of a piston preferably of brass, working vertically in a cylinder,
thus minimising the risk of corrosion so prevalent in those with pistons working
horizontally. The outlets of the valve are formed by casting or fixing one, two or
more short tubes on the body of the cylinder at A. Fig. 1., in the centre of
the water way B. Fig. 2. To these short tubes are attached brass, copper,
or other tubes which are carried to the bottom of the cistern or other receptacle
to be filled.
C. Fig. 2. is the piston closely fitted to the cylinder D and which for high
pressures is kept sound by means of a leather or india rubber ring E, or by a cup
leather fitted in the same groove or recess cut in the piston and held in position by
the cap F., which holds the seating washer G, or the cup leather or other packing
may be fitted in the cylinder H. For low pressures it is not necessary to employ
any packing whatever."
J. Fig. 2. is a throttle tube of brass or other material which is held in position
by a disc or plate screwed or soldered into the inlet of valve and preferably termi-
nating at the back edge of the seating of valve. This effectually prevents the
hissing noise when fixed on high pressures. The same effect is produced by casting
the body of valve with a water way equal to the bore of the tube, or by casting the
body solid and drilling the waterway to size required. But for economy the tube
is preferable. The throttle tube and disc arrangement can be made separately,
and fitted to any other kind of valve to prevent noise, or to check the pressure.
Either of the tubes A. Fig. 1. may be carried into the down pipe supplying the
closet or other apparatus at the most convenient point. To supply the afterflush
and the other retained for filling the cistern or waste preventer, the action is as
follows: When the valve is in action the water is flowing through both tubes, one of
which is filling the cistern, and the other supplying the afterflush to the closet or
other apparatus. When the cistern is full both supplies are shut off. The quantity
of afterflush may be regulated either by the size of the tube or by inserting a
regulating valve in the tube. To ensure the certain working of this arrangement
the tube supplying the cistern is connected to the body of the valve at a lower point
than the one supplying the afterflush, this ensures the cistern filling at every action,
as in case of a leak the water would flow through the lower tube, but could
only flow through the upper one when the valve is running at full bore. The
same arrangement can be fitted to those valves which have their pistons working
horizontally.

Improvements in the Construction of Ball Valves.
We ANDREW GIFFORD SOUTTER of 9 Bury Street, E.C., and WILLIAM
COTTRELL, 9 Bury Street, E.C. Sanitary Engineers, 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 :-
This invention relates to an improvement in the construction of ball valves, and
the object sought to be attained is, that first, the cistern, waste preventer, or other
receptacle can be filled noiselessly, secondly, that one or more cisterns, waste
preventers, or other receptacles can be filled by the one and same valve, and
thirdly, the one and same valve can be used both for filling the cistern, waste
preventer, or other receptacle, and giving an afterflush to the water closet or
other apparatus.
Referring to the drawings filed with the Provisional Specification, the valve
consists of a piston preferably of brass, working vertically in a cylinder, thus
minimising the risk of corrosion so prevalent in those with pistons working
horizontally. The outlets of the valve are formed by casting or fixing one, two,
or more short tubes on the body of the cylinder at A. Fig. 1, in the centre of the
water way B. Fig. 2. To these short tubes are attached brass, copper, or
other tubes which are carried to the bottom of the cistern or other receptacle
to be filled.
C Fig. 2 is the piston closely fitted to the cylinder D and which for high pressure
is kept sound by means of a leather or india rubber ring E, or by a cup leather
fitted in the same groove or recess cut in the piston and held in position by the
cap F., which holds the seating washer G, or the cup leather or other packing
may be fitted in the cylinder D. For low pressures it is not necessary to employ
any packing whatever.
J. Fig. 2 is a throttle tube or waterway of brass or other material which is open
at both ends and held in position by a disc or plate screwed or soldered into the
inlet of valve and preferably terminating at the back edge of the seating of valve.
This effectually prevents the hissing noise when fixed on high pressures. The same
effect is produced by casting the body of valve with a waterway equal to the bore
of the tube, or by casting the body solid and drilling the waterway to size required,
but for economy the tube is preferable. The throttle tube and disc arrangement can
be made separately and fitted to any other kind of valve to prevent noise, or to
check the pressure.
Either of the tubes A Fig. 1 may be carried into the down pipe supplying the
closet or other apparatus at the most convenient point to supply the afterflush and
the other retained for filling the cistern or waste preventer. The action is as
follows: When the valve is in action the water is flowing through both tubes, one
of which is filling the cistern and the other supplying the afterflush to the closet or
other apparatus, when the cistern is full both supplies are shut off.
The quantity of afterflush may be regulated either by the size of tube or by
inserting a regulating valve in the tube. To ensure the certain working of this
arrangement the tube supplying the cistern is connected to the body of the valve
at a lower point than the one supplying the afterflush, this ensures the cistern filling
at every action, and in the case of a leak the water would flow through the lower
tube, but could only flow through the upper one when the valve is running at full
bore. The same arrangement can be fitted to those valves which have their pistons
working horizontally.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a ball valve with its piston working vertically and having its outlets at the

page_text: top instead of the bottom and those outlets extended to the bottom of cistern, and
in conjunction with the throttle tube as before described, the noise in filling the
cistern is thus overcome.
2. That the ball valve having more than one outlet the filling of a great number
of cisterns or other receptacles can be controlled by the one and same valve.
3. That either of the pipes as before described can be used for giving a supply of
afterflush water to water closets or other apparatus substantially as described and
illustrated in the accompanying drawings.
