COMPLETE SPECIFICATION.
Improvements in or relating to Valves or Tons.
I, JOSEPH BOOTH BUTTERFIELD, of Ivy House, Thornton Road, Bradford, in
the County of York, Engineer, 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 :-
This invention relates to improvements in valves or taps such as are employed
for regulating or controlling the supply or distribution of water, oil, steam or other
fluids, liquids, or gases, and its object is to construct a simple valve or tap, the plug
of which may be readily ground to its seat, thus dispensing with the use of internal
packings for making a tight joint.
IL 1.
I, JOSEPH BOOTH BUTTERFIELD, of Ivy House, Thornton Road, Bradford, in
the County of York, Engineer, 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 :-
This invention relates to improvements in valves or taps such as are employed
for regulating or controlling the supply or distribution of water, oil, steam or other
fluids, liquids, or gases, and its object is to construct a simple valve or tap, the plug
of which may be readily ground to its seat, thus dispensing with the use of internal
packings for making a tight joint.
the drawings.
Fig. 1 is a sectional elevation,
Fig. 2 a plan looking at the top,
Fig. 3 a sectional plan on line
y Fig. 1, and
Figs. 4 and 5 are part end elevations of a valve or tap constructed according to
invention.
A is the outer casing of the valve or tap provided with any desired number of
inlets a, a, a² and an outlet a³ which are arranged to communicate with the interior
of the valve as shown. In the drawings I have shown three inlets, but when
preferred they may be increased or decreased as circumstances may require, and
the inlet and outlet may be provided either with internal screw threads or flanges
for the attachment of suitable connecting pipes. In some cases and when preferred
instead of providing the outlet as at the side of the casing as shown it may be
arranged in the bottom cover a'. Instead of arranging the passage a³ to communicate
with the interior of the casing directly opposite to or in a line with the opening a³
it is deflected downwards to permit of its orifice being arranged below the lowest
portion of the plug B.
B is the hollow self fitting plug which may be with one or more openings 64 65
and tapered as shown and armed with a square (or hexagon) head 6' for the reception
of a key or handle for turning the same. The plug is retained in the working
position shown by a nut b² to aid in forming a tight joint. The plug is perforated
at (and b) to permit of a communication being formed with its interior b.
When steam, water, gas, or other fluid is admitted say at one or more of the
openings a (and a¹); one or more of the other inlets may then be closed by the
plug, and the water or its equivalent after entering the interior of the plug (through
one or both of the openings 646°) is passed down the plug and enters the orifice
(below the plug) of the passage a' by which it is conducted to the outlet a³. By
this means water or its equivalent may be admitted simultaneously at one or more
of the inlets a, a', a² and conducted to the outlet a³, or when preferred a³ may be
used as an inlet and a, a', a² as outlets for distribution purposes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The improvements in or relating to valves or taps consisting essentially in
arranging any desired number of inlets (or outlets) to communicate, one or more
at a time, with an outlet (or vice versa) through the interior of a self fitting hollow
plug and a passage arranged with its inner orifice below the lowest point of the plug
substantially as herein set forth and illustrated in the accompanying drawings.
2. A valve or tap having inlets (or outlets) a, a¹ a² communicating with casing A,

municating with the interior of the casing below the lowest portion of the plug
by means of a passage a³, all arranged and combined substantially as herein set
forth and illustrated.
