PROVISIONAL SPECIFICATION.
A Silent Action Water Valve with Independent Float.
I, ALFRED PLATFORD, 7, Boston Road, Hanwell, Middlesex, Builder, do hereby
declare the nature of this invention to be as follows:-
A silent action water valve to be fixed under water line of cistern, with rubber
button attatched to lever, closeing against a rubber ring, secured to water inlet
with brass screwed cap, with independent float attatched to lever with chain or
other loose connections, with guide arm to support float fixed near top of cistern,
applicable to all kinds of water cisterns, flushing tanks & the like.

A Silent Action Water Valve with Independent Float.
I, ALFRED PLATFORD, 7, Boston Road, Hanwell, Middlesex, Builder, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
A water valve so arranged as to be silent in action & to give full waterway
when open applicable to all kinds of water cisterns, flushing tanks & the like
consisting of an inlet pipe having a valve at its lower end, actuated by a lever
similar so far to an ordinary ball valve, but differing from previous forms in
the following devices & arrangements which secure a full waterway & silent
action when open, allow a free escape, for dirt lead shavings & the like that
might prevent the proper closeing of the valve & make it more durable, & less
liable to get out of order, the lever is provided with a button (a) with a rounder
upper surface, preferably, of rubber or other elastic substance, closeing against
a seating (b) on the extremity of the pipe said seating as well as the button
aforesaid being preferably of rubber or other elastic material, though it may
be made with only one of the said surfaces of such elastic material. When
the seating at the end of the pipe is of rubber or the like, it is formed of a
rubber washer secured to end of pipe by a screwed cap (c). The lever is operated
by a float or other convenient device the fixed end of the lever is hinged to a
lug (d) near the end or mouth of the pipe & the free end is passed through a
guide (e) consisting of a vertical slot in an arm projecting downwards at an
angle from the bend of the pipe. The valve is fixed preferably near the bottom

page_text: of the cistern or tank & if a float is used in it is attached to the free end of
the lever by a chain (f) or other flexible connection & is kept in position by
a guide or arm (9), projecting from the side of the cistern or tank near the top,
the valve being placed thus under water renders it silent but if it is preferable
to have it above water the float may be attached to the lever in the ordinary
way & the other advantages of the invention retained namely the single or
double elastic seating & having the opening at the extremity of the pipe whereby
durability & a full waterway are secured, but in this case the screw cap securing
the rubber or other seating should be provided with a small continuation about
half an inch in length, forming a short pipe surrounding the button, to prevent
the escaping water spurting over at the sides.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is: :—
1. A valve having it seating at the extremity of the pipe whereby a full
waterway is given substantially as set forth.
2. A rounded button on the valve lever closeing against seating on, the mouth
of the pipe, either the button or seating or both, being of rubber or like elastic
material substantially as set forth.
3. Having both the button & seating of the valve of rubber or like elastic
material whereby the valve is made more durable, than when a rubber plug as
in ordinary cock closes against a metal seating.
4. A slotted arm attached to bend of pipe through which the lever passes,
& by which it is kept in accurate position substantially as set forth.
5. Attachment of float actuating lever to said lever by a chain or like flexible
connection so as to allow of the valve being placed below water & thereby making
it silent in action substantially as set forth.
Dated this 12th day of September 1898.
