PROVISIONAL SPECIFICATION.
Improvements in Ball Taps.
WILLIAM ROSs Junr... 78 Gregory Boulevard, Nottingham, in the County of
Nottingham, Engineer do hereby declare the nature of this invention to be as
follows:-
The tap herein described is an equilibrium ball tap.
The extremities of the barrel are bored out parallel, the lower part forming the
valve scat and outlet.
The middle part of the barrel, where it is joined by the inlet branch, is increased
in diameter to allow an annular space round the valve.
The lower part of the barrel may be made separate from the main body, to admit
of the valve seat being turned true.
The key or plug is made in sections, the upper section fitting easily into the
upper part of the barrel.
"The tail section is reduced in diameter and passes up through two flexible
washers, with a thimble or distance-piece between them, and is screwed into the
upper section; terminating in a conical tail which projects through the bottom end
of the barrel, thus enabling the washers to be tightened up without withdrawing
the key.
The upper washer above mentioned, forms the packing of the key, and works
within the upper part of the barrel.
The lower washer forms the valve, and works within the enlarged part of the
barrel, shutting off water when it rests on, or enters into, the lower part of the
barrel, which forms the valve seat.
The water, entering. by the inlet branch, between the washers; which are of
equal diameter; does not disturb the equilibrium of the valve, however great the
variation of pressure may be.
The tap is actuated by a lever and float. A spur or fulcrum is cast on the
barrel of the tap, and curving upwards passes through a slot in the lever, and is
fixed by a split pin.
The end of the lever enters a slot in the top of the key or plug, and forms a
lever of the first order.

COMPLETE SPECIFICATION.
Improvements in Ball Taps.
I WILLIAM Ross Junior of Seventy eight Gregory Boulevard Nottingham in
the County of Nottingham, 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 :-
The tap herein described is an equilibrium ball tap. The extremities of the
barrel Bare bored out parallel, the lower part O forming the valve seat and outlet.
The middle part of the barrel B, where it is joined by the inlet branch I is
increased in diameter to allow an annular space round the valve V. The lower
part of the barrel may be made separate from the main body B to admit of the
valve seat being bored true. The key or plug is made in sections, the upper
section K fitting easily into the upper part of the barrel B. The tail section T of
the key or plug is reduced in diameter and passes up through two flexible

into the upper section K terminating in a conical tail projecting through the bottom
end of the barrel O, thus enabling the washers P. V, to be tightened up without
withdrawing the key or plug, or the upper section K may have its lower extremity
reduced in diameter and screwed into the lower section T. The upper washer P
forms the packing of the key or plug, and works within the upper part of the
barrel B. The lower washer V forms the valve, and works within the enlarged
part of the barrel B, shutting off water when it rests on,, or enters into the lower
part of the barrel O, which forms the valve.seat. The water entering by the inlet
branch between the washers P and V which are of equal diameter, does not
disturb the equilibrium of the valve however great the variation of pressure may
be. The tap is actuated by a lever Land a float F. A spur or fulcrum S is cast
on the barrel B, and curving upwards passes through a slot in the lever L and is
fixed by a split.pin.. The end of the lever L enters a slot in the upper section of
the key K, and forms a lever of the first order.
I
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 1
'claim is
1st. The formation of an enlarged chamber in the barrel B into which the water
under pressure is admitted between the washers P and V which being of equal
area are in exact equilibrium in any position and under any pressure.
2nd. The formation of a conical tail T.on the lower section of the key or plug,
the base of the cone (which is inverted) fitting easily into the lower part of the
barrel O, forming a support for the flexible washer or valve V, and shutting off the
main flow of water.
3rd. The general construction of the tap substantially as herein described and
shewn in accompanying drawing, or any colourable imitation thereof.
Dated this 29th day of April 1891.
