Improvements in Ball Valves.
I, WILLIAM FREDERICK KING, of 3 Vauxhall Bridge Road, in the County of
Middlesex, Builder, do hereby declare the nature of this invention to be as
follows:-
My invention relates to ball valves such as are used in cisterns to automatically
stop the supply when a certain level has been reached; and it is designed to effect
this in a simple and efficacious manner, and by means of a device which shall bo
durable and simple.
I pivot the lever of the valve to any convenient part of the pipe or cock, and upon
this, either solid therewith or rigidly attached thereto, I form a plug with a circular
or approximately similarly shaped head, covered with india rubber or other suitable
material, forming a flexible envelope, which compensates itself to any irregularity in
the seating formed in the mouth of the valve. This seat is either formed suitably of a
cup so as to give as extended a surface of contact as possible, or with a lip shaped
orifice. The lever is prolonged to any suitable distance and carries a ball in the usual
manner, the flotation of which raises the plug into the seating, and stops the flow upon
any desired level being reached.

I, WILLIAM FREDERICK KING, of 3 Vauxhall Bridge Road, in the County of
Middlesex, Builder, 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:-
My invention relates to ball valves such as are used in cisterns to automatically
stop the supply when a certain lovel has been reached; and it is designed to effect this
in a simplo and efficacious manner, and by means of a device which shall be durable
and simplo.
In order that my invention may be the better understood I now proceed to describe
the same in respect of the drawings hereunto annexed, reference being had to the
letters and figures marked thereon. Like letters refer to like parts in both figures.
I pivot the lever A of the valve to any convenient part B of the pipe or cock; and
upon this, either boid therewith or rigidly attached thereto, I form a plug C with a
circular or approximately similarly shaped head D covered with india rubber or other
suitable material E, forming a Hexible envelope, which compensates itself to any
irregularity in the seating F formed in the mouth of the valve. This seat F is either
formed suitably of a cup (figure 2) so as to give as extended a surface of contact as
possible, or with a lip shaped orifice (figure 1). The lever A is prolonged to any
suitable distance and carries a ball in the usual manner, the flotation of which raises
the plug C into the seating F, and stops the flow upon any desired level being
reached.
In figure 1, I show the plug C affixed to the pivoted lover, fitted with a head E of
india-rubber, gutta-percha, leather or other suitable flexible or clastic material
dovetailed into the top D of the plug stem.
In figure 2, I show the plug stem C with a spherical head D covered with an elastic
envelope E, of india rubber, gutta-percha or similar material, which is retained
thereon by the shape of the head D of the plug.
It is obvious that I may use or apply this valve in a variety of different applications
and mechanisms without departing from the nature of my invention.
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 :-
1st. In a ball cock a plug fixed upon the pivotted ball lover and covered and
terminated with an envelope or head of india rubber or other flexible or elastic
material in combination with a cupped or circular seating.
2nd. The construction of the ball cock plug and seating substantially as described.
