Improvements in Float-ball Cocks.
I HENRY PARKIN of Carver Street, Birmingham, in the county of Warwick,
Mechanical Engineer, and WILLIAM CLARKE, of 15 Pittsford Street Birmingham in
the county of Warwick Jeweller do hereby declare the nature of this invention to be
as follows:-
This cock is used to regulate the supply (in tanks or otherwise) of water or liquids
in general. B (see drawing) is a ball attached to an eccentric camn-ended lever L
with camn C acting directly against valve V with either leather, rubber, or metallic
seating. The novelty in this improvement consists of:-firmly wedging the valve V
on to its seat; thereby preventing the valve (on any sudden accession or diminution
of pressure upon it) from causing the lever to rebound, and so preventing the wear of
valve and seat, which is a serious defect in all existing ball cocks. The eccentric
camn C is so graduated to form an acute wedge against valve V.

Improvements in Float Ball Cocks.
We HENRY PARKIN of Carver Street Birmingham in the County of Warwick
Engineer, and WILLIAM CLARKE 15 Pitsford Street in the County of Warwick
Jeweller 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
No alteration is made as concerns the drawing furnished with provisional Specification.
The valve is acted upon by an eccentric cam-ended lever, with the float ball
attached to it, and so graduated to form an acute wedge against the valve, thereby
preventing the rebounding of the valve or lever, upon any sudden accession or
diminution of pressure; which greatly injures the valves or valve seats in all other
float ball cocks. The valves and seats can be made of leather, india rubber or metal.
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
1 claim is
.
The locking of the valve on the seat with the cam, so as to prevent the valve being
acted upon save by the lever with ball attached.
