IMPROVEMENTS IN BALL TAPS OR VALVES
Year: 1884

page_text: I, THOMAS GAMESON of Mount Street, Walsall, in the County of Stafford,
Malleable Iron founder, do hereby declare the nature of said invention for
"IMPROVEMENTS IN BALL TAPS OR VALVES," to be as follows:-
My invention consists of the improvements hereinafter described in what are
commonly known as ball taps or valves for shutting off the flow or supply of water
to cisterns and other chambers when the water has risen therein to a certain level,
and on the other hand, when the water falls to a lower level the supply valve is
opened by the falling of the ball.
By my improvements ball taps or valves are made much simpler in their con-
struction and more efficient in their action than those of the ordinary construction,
and moreover dispensing with the use of leather or rubber valve facings as are
commonly employed.
In constructing a tap or valve according to my invention, the body of the tap or
valve is preferably made angular or elbow-form; that is, the part in which the
valve stem or plug works is at right angles to the other part, and depends or hangs
downwards and forms the outlet passage-A fulcrum bracket is attached at the
lower end of the depending part of the body and has jointed to it, the ball stem
which passes through a slot or opening in the lower part of the valve stem, working
within the outlet passage and near the top of the said passage a conical seat is
formed out of the solid of the metal; and into this conical seat, a conical nose on
the extreme end of the plug or stem accurately fits. The plug or stem is also
coned near the conical nose which fits into a like coned part in the outlet passage
of the valve body--The lower part of the stem is made angular, so as to admit of
the passage of water when the ball stem is lowered, and the orifice of the
valve seat open. The said orifice is of small diameter, consequently there is a
diminished pressure of water upon the valve seat, thereby rendering the valve more
certain in its action, and little liable to leak, from the fact that no interposing
leather or rubber facings are used, and consequently little or no wearing away of
the parts which come in direct contact with each other, as there is only metal to
metal in the valve seating.

I, THOMAS GAMESON of Mount Street Walsall, in the County of Stafford,
Malleable Iron Founder, do hereby declare the nature of said invention for
"IMPROVEMENTS IN BALL TAPS OR VALVES," and in what manner the saine is to
be performed, to be particularly described and ascertained in and by the following
statement:
My invention consists of the improvements hereinafter described in what are
commonly known as ball taps or valves for shutting off the flow or supply of water
to cisterns and other chambers when the water has risen therein to a certain level,
and on the other hand, when the water falls to a lower level the supply valve is
opened by the falling of the ball.
By my improvements ball taps or valves are made much simpler in their con-
struction and more efficient in their action than those of the ordinary construction,
and moreover dispensing with the use of leather or rubber valve facings as are
commonly employed.
In constructing a tap or valve according to my invention, the body of the tap or
valve is preferably made angular or elbow form; that is, the part in which the
valve stem or plug works is at right angles to the other part, and depends or hangs
downwards and forms the outlet passage-A fulcrum bracket is attached at the
lower end of the depending part of the body and has jointed to it, the ball stem,
which passes through a slot or opening in the lower part of the valve stem working
within the outlet passage, and near the top of the said passage a conical seat is
formed out of the solid of the metal; and into this conical seat, a conical nose on
the extreme end of the plug or stem accurately fits-The plug or stem is also
coned near the conical nose which fits into a like coned part in the outlet passage
of the valve body-The lower part of the stem is made angular, so as to admit of
the passage of water when the ball stem is lowered, and the orifice of the valve
seat open-The said orifice is of small diameter, consequently there is a diminished
pressure of water upon the valve seat, thereby rendering the valve more certain in
its action, and little liable to leak, from the fact fact that no interposing leather or
rubber facings are used, and consequently little or wearing away of the parts which
come in direct contact with each other, as there is only metal to metal in the valve
seating.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which the same is to be performed.
Figure 1 represents in longitudinal vertical section a ball tap or valve constructed
according to my invention, the said cock or valve being closed-Figure represents
the same with the valve open-Figure 3 shows a transverse section of the said
valve on the dotted lines A B figure 1. Figure 4 is a transverse section of the
body or tap separately and figure 5 is an underside view of the same-Figure 6 is
a front and edge view of the valve stem showing the conical formation at its
summit, and the narrowed or cut away sides to permit of the passage of the water,
on the conical nose being removed from its equivalent conical seat in the body.

page_text: The same letters of reference indicate corresponding parts in the several figures
of the Drawing.
a is the body of a ball tap or valve which is elbow form; that is, the part a* in
which the valve stem or plug b'works, depends or hangs from the inlet part a³, and
the said depending part a forms the outlet passage, while the other part a³ which
is at right angles thereto forms the inlet passage-The outlet passage is provided
with a hanging bracket at, upon which the end of the ball stem c is jointed and
turns upon, as a fulcrum-c2 is the fulcrum pin or linch cotter, best seen in figure 3
-The ball stem c also passes through the hole or opening b² in the lower extremity
of the valve stem or plug, the upper end of which said plug or stem has a conical
nose b which fits into (when the valve is closed) a like conical seat a³, truly made
out of the solid of the metal formed by the junction of the inlet and outlet passages.
The stem or plug of the valve is also cut away on both sides and marked b b₁ so
as to admit of the passage of the water through the outlet on the valve being
opened. d is the ball float of the valve attached to the end of the stem c.
The action of the valve is as follows, on water being withdrawn from a cistern
provided with a valve as described, the float falls, turning the ball stem upon its
fulcrum centre, and thereby lowering the plug or stem b and withdrawing its
conical upper end 63 of the said stem, from the conical seat a' in the body of the
valve, and so allowing water to flow from the outlet passage a² as best seen in
figure 2. On the rising of the water in the cistern, the ball float d gradually rises
and shuts off the water by the ball stem, raising the valve stem, and pressing the
conical nose at its summit, into the like conical seat truly formed out of the solid
metal of the valve body, and thereby shutting off the supply of water, as best seen
at figures 1 and 3.
The orifice of the valve seat being of small diameter, there is consequently a
diminution of exerted pressure upon the conical end of the plug and upon the valve
seat;
and as there are no interposing leather or rubber facings, there is little or no
wear of the parts, which come into immediate contact with each other; from the
fact that there only bare metal to metal, in the valve seating; thereby rendering
the valve more certain in its action, and little liable to leak or get out of order.
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
The improvements in ball taps or valves hereinbefore described and illustrated
in the several figures of the Drawing; that is to say, dispensing with the use of
leather or rubber valve facings, and substituting therefor a plug or stem baving
upon its summit a plain conical end, which fits into a like accurately coned seat,
truly formed out of the metal of the tap or valve, so that there is only metal to
metal in the valve scating, or in the parts which come into immediate contact, for
the stopping off or closing of the valve orifice, the parts being arranged, combined
and acting in the way and for the purpose substantially as set forth.
