PROVISIONAL SPECIFICATION.
An Improved Ball Valve for Cisterns, Boilers, and other purposes.
I, WILLIAM ERRINGTON, 42, Hanover Park, Peckham, London, S.E., Com-
mission Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved ball valve for cisterns, boilers and other
purposes. In carrying out my invention I provide a ball which is carried in a
suitable chamber, this chamber being provided with a seating of india rubber
or such like suitable substance, providing a tight joint between the seat and
ball. The ball is raised from this seat when required by means of a lever, one
end of which engages upon the under side of the ball, the other end being
operated when required to raise the ball from the seating. This lever may pass
through the pipe or tube in which the case the joint may be rendered tight by
suitable packing. By this arrangement in the case of cisterns for use in closets
a supply of water is readily obtained, and upon releasing the lever is at once
stopped owing to the weight of the liquid above forcing the ball into its seating,
the weight of the ball also aiding this operation. The ball valve is placed in
any suitable position between the supply and outlet. If desired, the lever might
be formed of any suitable length and carry a float at one end so as to enable the
valve to be employed for the filling of cisterns as required.

I, WILLIAM ERRINGTON, 42, Hanover Park, Peckham, London, S.E., Com-
mission Agent, 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 improved ball valve for cisterns, boilers, and other
purposes. In carrying out my invention I provide a ball which is carried in a
suitable chamber, this chamber being provided with a seating of india rubber
or such like suitable substance, providing a tight joint between the seat and
ball. The ball is raised from this seat when required by means of a lever, one
end of which engages upon the under side of the ball, the other end being

page_text: suitable packing. By this arrangement in the case of cisterns for use in closets
a supply of water is readily obtained, and upon releasing the lever is at once
stopped owing to the weight of the liquid above forcing the ball into its seating,
the weight of the ball also aiding this operation. The ball valve is placed in
any suitable position between the supply and outlet. If desired, the lever might
be formed of any suitable length and carry a float at one end so as to enable the
valve to be employed for the filling of cisterns as required.
Referring to the annexed drawings,
Figure 1, is a sectional side elevation shewing my invention in position.
Figure 2, front view.
a is a lever which engages with the ball b which, when in its closed position,
rests upon the seating c. The end d of the lever e may be operated by any suit-
able means, such as by the hand. The plug f which carries the levers a and e is
secured upon suitable bearings g, h being a nut for the purpose of maintaining
the plug in close contact with the aperture in the pipe i which is shaped so as
to conform to the configuration of the plug. I find it convenient sometimes to
form this plug tapered in order to enable any wear to be taken up. If desired,
any suitable form of packing may be employed for the purpose of maintaining
a tight joint. When the end of the lever e is moved in the direction of the
arrow 1 the lever rod a will engage upon the bottom of the ball b and raise same
from the seating, thus allowing water to pass. Upon releasing the end of the
lever e, the weight of the ball and the action of the water will tend to bring the
ball back to the closed position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
claim is:
1. In valves of the class herein described the combined construction and
arrangement of the various parts substantially as described and illustrated herein
and for the purpose set forth.
2. In valves of the class herein described: a lever pivotally carried through
the medium of a plug or such like convenient means, for maintaining the joint
between the pipe and the plug, with or without packing: one end of a lever
carried by the plug operating a ball which closes the seating in the interior of
the pipe, the exterior end being operated by the hand or other convenient means
for the purpose of removing the ball from its seating when required, substantially
as described and illustrated and for the purpose herein set forth.
