PROVISIONAL SPECIFICATION.
Improvements connected with Cistern and like Ball Taps.
I, OTHO HENRY STEED, Junior, of 17 St. Pauls Road, Tottenham, Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain detail construction or arrangement of Ball Taps
for Cisterns and like vessels.
For the purpose of my said invention, I make the barrel part next the valve with
an annular groove preferably by a swelling from which the nozzle depends for the
collection of, water, it has preferably a metallic seating but an adjustable washer or
end piece can be fitted as desired, so that the water after passing the valve has a free
exit. The stem of the barrel is screw threaded and the valve stem also to work
round therein when the ball lifts to remove the valve from its seating, the valve being
on the inner end to fit against a seating of the barrel opposite the end which is
secured to the supply or service pipe.
The screwed portions are very short yet of sufficient length to prevent the valve
jumping if the valve be suddenly acted on from any cause.
The valve opens against water pressure, so that when the ball is up a tight
joint or water seam is ensured, said valve and its seating may be slightly cone
shaped or flat.

I OTHO HENRY STEED, Junior, of 17 St. Pauls Road, Tottenham, Middlesex,
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 certain detail construction or arrangement of Ball Taps
for Cisterns and like vessels.
My invention will be clearly understood from the following description aided by
the accompanying drawings in which
Figure 1 is a sectional plan with valve closed.
Figure 2, side elevation.
Figure 3, section through the line a, a of Figure 1.

page_text: Figure 5, side view in section with the valve open.
For the purpose of my invention I make the barrel part A with an annular groove
or grooves for containing the valve seating B (preferably leather) and on which the
valve C rests when the tap is closed.
The interior lower part of the barrel A is formed with a single or double screw
thread into which the screw thread D of the valve stem E engages when in
position.
Fare grooves cut in the side of the valve stem to establish communication between
the inlet G which is screwed to the service pipe and the delivery nozzle H.
The outer end I of the valve stem is shaped to hold, by a screw or otherwise, the
arm J of the ball K so that the valve C can be opened or closed according to the
movement of the ball K.
L is a stop or projecting lug from the end of the barrel A to limit the drop of
the ball K and lever J.
The screwed portions are of sufficient length to prevent the valve jumping if the
valve be suddenly acted on from any cause.
M is a cap to close the end of the barrel A and its removal permits of a new valve
seating being placed in position should a leak occur, without removing the tap from
the service pipe or to enable the valve to be placed in position or removed in case of
repairs.
The valve C opens on the lowering of the ball and against water pressure and the
water passes through the grooves F in the valve stem E and when the ball K is up a
tight joint or water seam is ensured, said valve and its seating may be slightly cone
shaped or flat.
The valve stem E is reduced in size between the grooves F and the screw threaded
portion D for easy passage of water to the outlet H but a swelling or enlargement of
the barrel A at the outlet part may be provided for the same purpose.
It will be understood that by the screw giving the valve a reciprocating circular
motion a firm and watertight seating is ensured to the valve when the ball has risen
sufficiently without fear of being fixed so tight as to prevent the valve opening when
the water is lowered in the cistern.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is
A ball tap constructed of barrel A internally screw threaded at its lower part, screw
threaded valve stem E for rotation therein, reciprocating valve C, grooves Fon said
stem E, seating B recessed into barrel A, stop L and nozzle H depending from the
barrel A, the moving parts being operable from and by the ball K all as herein
described and as represented on the annexed drawings.
