I DAVID GILL of High Street in the Town of Weston-super-Mare, in the
County of Somerset, Sanitary Plumber, do hereby declare the nature of this
invention to be as follows:-

These
My invention consists of a ball-tap with two valves as follows. First: A hollow
spindle with a slet near one end of same into which is fixed the stem of the ball..
Second: Two workable valves are mounted on the other end of the same, one
above the other, the upper one being less in size than the lower one.
valves are mounted in such a manner as to allow free play on the said spindle
whilst in work, between screw-nuts or pins; and under each valve there is a raised
metal ring on which the valves are pressed by the downward action of the ball
lever and the pressure of the water above. Third: The spindle may be made to
serve as the water way of the upper valve by making a hole or holes in the same
near the seating. Fourth: The said spindle and valves are mounted in a metal
cylinder with guides for working the same; the cylinder being provided with a
screw end for screwing the same into the barrel of the tap to serve as the water
outlet, and the stem of the ball is attached for working the same. Fifth, and
lastly: A metal screw with a graduated groove is screwed into the inlet end of
the tap by which means the water supply can be regulated.
These improvements are applicable to other water taps.

COMPLETE SPECIFICATION.
Improvements in Ball-valves and other Water-taps.
I, DAVID GILL, of High Street in the Town of Weston-super-Mare in the
County of Somerset, Sanitary Plumber, 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:-
as
My invention consists of a ball-tap with two valves and a graduated screw,
follows. First: A hollow spindle with a slot near one end of same into which is
fixed the stem of the ball. Second: Two workable valves are mounted on the
other end of the same, one above the other, the upper one being less in size than
the lower one. These valves are mounted in such a manner as to allow free play
on the said spindle whilst in work, between screw nuts or pins, and under each
valve there is a raised metal rim on which the valves are pressed by the down-
ward action of the ball lever and the pressure of the water above. Third: The
spindle is made to serve as the water-way of the upper valve by making a hole
or holes in the same near the seating. Fourth: The said spindle and valves are
mounted in a metal cylinder with guides for working the same. The cylinder
being provided with a screw end for screwing the same into the barrel of the tap
to serve as the water-outlet, and the stem of the ball is attached for working the
same. Fifth, and lastly: A solid metal screw with a tapered groove on the side
thereof is screwed into the inlet end of the tap, movable in and out, by which
means the amount of water supply can be regulated. These improvements are
applicable to other water taps.

page_text: The principal parts are-A: the barrel of the tap. B the cylinder. C: the
ball. The other parts are, a² the hollow spindle, the slot, c² the stem of the ball
d, d are the workable valves, e, e, are raised metal rims, f,f: are holes in the
upper valve, gg: are metal guides, h, the screw end for screwing the cylinder into
barrel. is the screw with tapered groove on the side to regulate the supply of
water.
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 A water tap having a basin shaped head with female screw therein which I
name the valve chamber.
2 A moveable nozzle with screw end and workable valves mounted therein.
3 A workable screw piece in the inlet of the said tap, having a tapered groove
thereon to regulate the supply of water all substantially as described.
