I WILLIAM WALTER ADAMS Brass Finisher of 38 Murray Street Hoxton in
the County of Middlesex do hereby declare the nature of my invention for
IMPROVEMENTS IN VALVES FOR BIB STOP AND BALL COCKS to be as follows:―
This Invention has for its object an improved ball valve which may be fitted
with equal advantage either to a bib or stop cock or to a ball tap or other high or
low pressure water fittings.
f
Such improved ball valve is so constructed and arranged that it is either raised
or drawn from its seating or depressed thereon by the action of the tap spindle or
lever as the case may be.
وا
To carry out my invention I proceed as follows-I fit the base of the spindle of
abib or stop cock with a metal frame consisting of two flat rings connected
laterally by suitable arms or their equivalents-The bottom ring serves to carry a
rubber ball valve which is kept in position by the connecting arms while the upper
ring forms a collar that fits round and works loosely on the base of the spindle
thus securely attaching the frame thereto.
+
In order to prevent friction and protect the rubber ball from being injured by
the up and down motion of the spindle I provide a shield plate of any convenient
shape against which the base of the spindle butts when the cock is closed-Such
shield plate is furnished with a pin or projection that lodges in a recess formed in
the centre of the base of the spindle Sufficient space is left between the screw
thread on the spindle and its base to allow of the easy play up and down of the
collar of the frame and also of the pin of the shield plate in its socket as the valve
is either opened or closed.
In applying my invention to ball taps for Cisterns and other similar purposes it
is only necessary to cast or otherwise form a suitable lug on the frame to which the
lever can be attached so that as such lever rises or falls the ball valve is drawn from
or pressed to its seating as the case may be.
My invention combines the essential advantages of simplicity efficiency and
durability as owing to the numerous and varying surfaces presented by the ball to
the action of the spindle or lever the constant wear upon one particular portion of
the valve which has hitherto been inevitable is totally obviated while the
infallibility of its action is secured owing to the ball being mounted in a frame
attached to the base of the spindle or to the lever in the manner already described.
Dated this 23rd day of September 1884.

declare the nature of my invention for IMPROVEMENTS IN VALVES FOR BIB, STOP,
AND BALL COCKS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This Invention has for its object an improved ball valve which may be fitted.
with equal advantage either to a bib or stop cock or to a bill tap or other high or
low pressure water fittings.
Such improved ball valve is so constructed and arranged that it is either raised
or drawn from its seating or depressed thereon by the action of the tap spindle or
lever as the case may be.

Fig of the accompanying drawings shews a view partly in section and partly
in elevation of a tap constructed according to my invention-The remaining
Figures show detail views of the various parts.
To carry out my invention I proceed as follows:-I fit the base of the spindle of
a bib or stop cock with a metal frame consisting of a flat ring a furnished with a
screw threaded collar b that takes into a cylindrical' socket c having a suitable alot
formed therein to allow of such socket being readily alipped on or off the tap
spindle or such frame may consist of two flat'rings connected by suitable connecting
arms or their equivalente placed either vertically or obliquely or otherwise as shown
at Figs 6, 7-The bottom ring a serves as a seating for a rubber ball d which is
kept in position by the connecting arms or by the cylindrical socket while either
the upper ring or the socket forms a collar that fits round and works loosely on the
base of the tap spindle thus securely attaching the frame thereto.
In order to prevent friction and protect the rubber ball from being injured by
the up and down motion of the spindle I provide a cap or shield plate e of a
circular or any other convenient shape against which the base of the tap spindle
butts when the cock is closed-Such shield plate is furnished with a pin 'or
projection that lodges in a recess formed in the centre of the base of the tap
spindle Sufficient space is left between the screw threaded collar on such spindle
and its base to allow of the easy play up and down of "the frame, and also of the
pin of the shield plate as the valve is either opened or closed.
In applying my invention to ball taps for cisterns and other similar purposes it
is only necessary to cast or otherwise form a suitable lug on the frame to which
the lever can be attached so that as such lever rises or falls the ball valve is drawn
from or pressed up to its seating as the case may be.

By this improved construction of ball valve I obtain a readily adjustable bearing
that ensures the ball being easily and effectually pressed liome to it thus thoroughly
obviating all leakage and waste.
It will be found that my invention combines the essential advantages of
simplicity efficiency and durability as owing to the numerous and varying surfaces
presented by the ball to the action of the spindle or lever the constant wear upon
one particular portion of the valve which has hitherto been inevitable is totally
obviated while the certainty of its action is secured owing to the ball being mounted
in a frame or cage attached to the base of the spindle or to the lever in the manner
already doonrihed

page_text: Another advantage of my invention is that it affords great facilities for effecting
repairs when necessary.
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
1° Fitting a bib or stop cock with a frame or cage, ball, and cap or shield plate
all constructed combined arranged and fitted substantially in the manner and for
the purposes herein before specified and shewn.
2° The application of my invention to ball taps for cisterns and other similar
purposes.
