RICHARD NEWBERY 25 Church Street, Greenwich Wine Merchant, do hereby
declare the nature of this invention to be as follows:-
An Improved Cistern Ball Cock Valve composed of Metal with Inlet and Outlet
and pressure piston acted upon by Lever, regulated by Water, the mechanical Con-
struction of Interior being an India rubber or composition Ball, acting as Stop Valve
between Cups or Sockets, kept in position by guiding Rods.
An improved Cistern Ball Cock valve.

I RICHARD NEWBERY 25 Church Street Greenwich Kent, Wine Merchant, 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 :-
The object of this invention is to prevent the possibility of the Valve getting choked
with
any
substance and so prevent the Valve from closing and shutting off the supply
of liquid in answer to the action of a rising lever.

page_text: To accomplish this I construct my Valve in the following manner, viz.:
I construct a chamber with an inlet and an outlet, the sectional area of the inlet
never being larger than that of the outlet. In this chamber is placed a Ball which
when pushed against the inlet closes this aperture and makes a water tight joint,
opposite to this inlet a pressure piston is placed in a line with the Centre of the Ball
and the inlet. One end of this piston is outside the chamber and is acted upon by a
lever, on the other end of this piston which is inside the chamber is formed as a cup
or socket and acts upon the Ball, this Ball is guided towards the inlet by means of
ribs or guides placed lengthwise along the interior walls of chamber and these ribs or
guides also prevent the Ball from falling into and blocking up the outlet. When the
lever which regulates the supply of the liquid that may pass through the Valve, falls
down, the Ball in the chamber is free to move away from the inlet and allow the liquid
to pass through the Valve and out at the outlet, when the lever rises, it pushes forward
the pressure piston which in turn pushes forward the Ball into the inlet-space, closing
the opening and hermetically sealing the aperture thus shutting off the supply of
liquid.
In order that the nature of my said improvements may be more fully understood,
I will proceed to describe the several figures on the sheet of Drawings hereunto
annexed, all of which figures are marked with the like letters of reference throughout.
Fig. 1 is a geometrical elevation of the Valve according to my said improvements,
A is the chamber, B is the inlet, () is the outlet, D is the pressure piston projecting
through the chamber, E is the lever which acts upon the end of pressure piston D.
Fig. 2 is a transverse section of the Valve showing position of Ball, A is the
chamber, C is the outlet, F is the Ball, G G G are the ribs or guides for the Ball F.
Fig. 3 is a longitudinal section of the Valve.
As my said improvements are capable of various modifications without departing
from the principle thereof, I do not restrict myself to material, dimensions or the
precise form or placement of the several parts thereof.
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:
A Ball placed in the interior of a chamber, which is acted upon by a pressure piston
in one direction and by a force of liquid in the opposite direction, these two mediums
being the means of opening and closing the Valve.
