PROVISIONAL SPECIFICATION.
Ball Valves.
I HARRY JOHN BURGESS, 42 New England Road Preston, Brighton, Sussex Sign
Writer do hereby declare the nature of this invention to be as follows:-
A half ball being acted upon by the pressure of water or other liquid to the extent
that the valve is closed and on the lever ball or float falling by reason of the lowering
of the level of the water or other liquid the lever lifts the pin to which the half ball is
attached thereby opening the valve.
The advantages claimed being that the force employed to ensure a supply is hereby
in this invention used to prevent leakage and the action of the valve generally is
extremely easy.
The half hall forms the wolve

Ball Valves.
HARRY JOHN BURGESS 42 New England Road Preston Brighton Sussex 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 a certain novel construction or arrangement of ball valve
in which the pressure associated with the supply is utilized to materially assist in the
closing of the valve.
The manner of constructing my improved valve is shown in the annexed drawings
in which at Figure 1 the lever of the float or ball is placed as when the water or
other liquid is at the level desired the valve in other words being closed. The details
of the action of the valve is shown in Figure 2 the piston A working in a chamber of
sufficient length to ensure a perfectly true movement up and down the said piston
being slightly reduced in the upper portion and having at the top a valve B so arranged
as to fit (when the valve is closed) against an india rubber, leather or other washer C.
As here indicated the piston A acted upon by the lever of the float or bail the
valve B being removed from the washer C a free course is thereby opened for the
water or other liquid.
The action of the float or ball in this valve is the same as in ordinary ball valves in
so far as the incoming of the water or other liquid is concerned but in the opening of
the valve in this invention there is this difference that the valve is opened in opposition
to the supply pressure on the back of the valve B when by reason of the float or ball
falling the piston A with the valve B is levered off the washer C.
The rising of the float or ball is also as in other valves the cause of the stoppage of
the water or other liquid but in this invention the pressure on the back of the
valve B becomes an agent for the prevention of leakage by assisting to effectually
close the valve.
In place of rubber, leather or other washer C a metal washer may be employed for
a rubber or other valve to impinge against.

page_text: 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 I
claim is :-
:-
In ball valves that by the use of the principles as herein specified by drawings and
description a most reliable valve is obtained.
