IMPROVEMENTS IN VALVES FOR REGULATING OR CONTROLLING THE SUPPLY OF WATER FOR DOMESTIC OR OTHER PURPOSES
Year: 1884

page_text: I EBENEZER Pocock of Southwark Bridge Road in the County of Surrey do
hereby declare the nature of said invention for "IMPROVEMENTS IN VALVES FOR
REGULATING OR CONTROLLING THE SUPPLY OF WATER FOR DOMESTIC OR OTHER
PURPOSES" to be as follows:-
My invention relates to that class of valves known as ball-valves and comprises
the novel construction and arrangement of parts as hereinafter described.
In carrying my said invention into practice I provide a metal shell of suitable
construction having an inlet and an outlet.
To the upper part of the shell is pivoted the lever which carries the ball for
regulating or controlling the movement of the valve proper, and consequently the
quantity of water supplied. To the said lever is jointed a rod which passes down
by the side of the shell and through a guide attached to the latter. The lower end
of this rod is bent under the outlet in the shell and carries on its end a valve
proper which is preferably covered with India rubber. The said valve is adapted,
when the rod carrying it is raised by the ball and lever, to impinge against the face
of the outlet in the shell and close the said opening.
The size of the outlet must be so proportioned with relation to the floating ball
that the pressure of water in the pipes with which the valve is connected will not
cause the latter to leak.
The said rod instead of being jointed to the lever may be enlarged at its upper
end and have a slot formed therein through which the lever passes.
jointing the lever to the rod is thus dispensed with.
Dated this 7th day of January 1884.

COMPLETE SPECIFICATION.
I, EBENEZER Pocock, of Southwark Bridge Road, in the County of Surrey, do
hereby declare the nature of my invention for "IMPROVEMENTS IN VALVES FOR
REGULATING OR CONTROLLING THE SUPPLY OF WATER FOR DOMESTIC OR OTHER
PURPOSES " and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to that class of valves commonly known as ball-valves, and
comprises the novel construction and arrangement of parts as hereinafter described.
My improved ball-valve is illustrated in the accompanying drawing, in which
Figure 1 is a plan, and
Triungo vartioal longitudinal section

page_text: a is the shell or casing, which inay be of brass or other suitable metal, and which
has an inlet a¹ and an outlet a, b is the lever, which carries the ball or float for
regulating or controlling the movement of the valve proper, and which is pivotted
to the said shell or casing at b, c is a rod having a slot c', through which the said
lever is passed, and extending downward on one side of the shell or casing a
between guides d attached thereto, or formed integrally therewith. This rod is
bent or curved so that its lower end extends upward a short distance within the
shell or casing a, and the said rod carries at this end a valve e, which is covered
with india-rubber or is provided with a ring or disc of leather or other suitable
material, so that, when pressed against its seat, it will make a tight joint therewith.
I prefer to make the valve e in the form of an inverted truncated cone as shown,
and to place thereon an envelope, bonnet or covering f of india-rubber.
The rod c is flattened or cut away at c to enable it to be readily inserted, or
removed from, between the guides d.
The size of the outlet a must be so proportioned relatively to the buoyancy of
the ball or float that the maximum pressure of water in the pipe with which the
casing a is connected will not exert upon the valve sufficient force to overcome such
buoyancy and thus open the valve or prevent its closing.
The rod c may, if desired, be coupled to the lever b, but I prefer the construction
shewn as it enables me to dispense with a pin or bolt for coupling the said lever
and rod.
The operation of this valve is as follows, that is to say, when the ball or float
attached to the lever b is not supported by the liquid in the tank or other vessel to
which the said valve is applied, the pressure of the liquid in the supply pipe opens
the valve e; the liquid then enters the said tank or vessel and rises therein until
it lifts the said ball or float and closes the valve e thus shutting off the supply of
liquid to the said tank or vessel, as will be readily understood.
My ball-valve is applicable for regulating or controlling the supply of water to
houses or other buildings, or for similar purposes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. The improved ball-valve consisting of the parts constructed and combined
substantially as described with reference to the accompanying drawing and operating
as above specified.
Second. In a ball-valve, the employment, in combination with the valve proper,
of an envelope, bonnet or covering of india-rubber, substantially as, and for the
purpose, set forth.
