PROVISIONAL SPECIFICATION.
Improvements in or connected with Ball and Float Valves
I, JAMES WELLARD, of "Leynci oft," New Road, Grays, in the County of
Essex, Manager, do hereby declare the nature of this invention to be as follows
-
In ball cocks on valves as oıdımanly constructed the ball float is spherical in
form comprising two hemispherical cups secured together by a soldered joint and
having the valve lever soldered to the outside thereof. Owing to the constant
immeision the solder of the joint is subject to galvanic or other coniosive action,
the float being thereby rendered useless.
This invention has for its object to provide a float so formed that no joint
shall be exposed to the action of the liquid, thereby obviating prejudicial co110-
Bive action and consists in forming the float of a hollow vertical cylinder closed
at the bottom by a hemispherical or other curved end integral with the cylindrical
vertical part, the top end being closed by a flat cover plate secured to it by
solder in the ordinary manne It will thus be seen that the part of the float
subjected to immersion in the liquid is free from joints, col11osion of which
thereby avoided Suitable lugs are attached to the upper part of the float by
means of which it is secured to the end of the valve lever

Improvements in or connected with Ball and Float Valves
I, JAMES WELLARD, of "Leyncioft," New Road, Grays, in the County of
Essex, Manager, do hereby declare the nature of this invention and in what
manner the same 18 to be performed, to be particularly described and ascertained
in and by the following statement. —
In ball cocks or valves as ordinarily constructed the ball float 18 spherical in
form comprising two hemispherical cups secured together by a soldered joint and
having the valve lever soldered to the outside thereof Owing to the constant
immersion the solder of the joint is subject to galvanic or other coroave action,
the float being thereby rendered useless.
This invention has for its object to provide a float so formed that no joint
shall be exposed to the action of the liquid, thereby obviating prejudicial cono-
sive action, and consists in forming the float of a hollow vertical cylinder closed
at the bottom by a hemispherical or other curved end integral with the cylindrical

The accompanying drawing shows a side elevation of a ball cock on valve pio-
vided with a float constructed according to this invention
The float is formed of a hollow vertical cylinder closed at the bottom by a
hemispherical end integral with it, the top end being closed by a flat covei
plate secured by solder in the ordinary manner.
The valve level c is secured to the float by means of lugs d secured to the
upper part of the float and through which the end of the valve level is passed.
It will thus be seen that the part of the float subjected to immersion in the
liquid is free from joints, co110sion of which is thereby avoided Suitable lugs
are attached to the upper part of the float by means of which it is secured to
the end of the valve lever
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 18-
1 The combination with a ball cock or valve of a float formed of a hollow
cylinder having a bottom part formed integial with it and lugs for securing
it to the valve lever substantially as described
2. A float for ball valves or cocks constructed substantially as described with
1eference to the diawings
