1, 18AAC DARNSLEY Of Charles Street, in the City of Shetheld Manufacturer
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 :-
My invention relates to the improved and novel construction of ball or float taps,
which I have clearly illustrated in the annexed sheet of drawings.
Fig. 1, front elevation of the tap.
Fig. 2, interior construction of body.
Fig. 3, side elevation.
Fig. 4, front and side views of nut.
Fig. 5, screw valve.
Fig. 6, valve frame, half in section.
Fig. 7, adjusting cap, half in section.
In the construction of a ball or float tap such as shown in the drawings, I cast
the body A, as shown in Fig. 2, having a horizontal water way B, terminating in
a central port or opening B', surrounded by a raised seat B2, which opens into a
large chamber C, from which another opening D, communicates with the outlet E.
The chamber C, is closed by a circular and elastic diaphragm or disc F, which
is held between the circular facing of the body and a corresponding facing G, on
the valve frame H, Fig. 3, the two being held together by the screws I.
The valve frame H, has a central opening J, to receive a nut K, and is bored
out to receive an adjusting cap N, and a valve P.
The nut K, is provided with projecting lugs L, and M, the lug L, to receive
the rod V, carrying the ball or float, and M, to carry a short rod W, with a weight
to counterbalance the float or thereabouts; it has also two collars K¹ and K³, upon
which it turns, and which fit in recesses J Fig. 6, and N2, Fig. 7.
The centre hole is screw-threaded to receive the screwed valve Fig. 5.
The valve is provided with a flat head for pressing the diaphragm F, against the
raised seat B to close the tap, and also a tail piece Q, of any suitable cross sectional
form that will prevent the valve turning round when the said tail-piece is passed
through a correspondingly shaped hole S, made through the cap N, that in the
drawing is shown round with a flat upon it.
The cap by means of which the position of the valve is adjusted fits into the
end of the frame H, see Fig. 3, and is secured in the desired position by means of
the screw u, which is screwed down against the bottom of the groove T.
When the various parts of the tap are put together as shown in Figs. 1, and 3,
if the cap N, is turned round with the fingers it will also turn the screwed valve in
the nut K, and cause it to alter its position with relation to the diaphragm, nearer
to or farther from it as the case may be, and when the proper position is found,
the cap is fixed there by the screw U..
Supposing the tap adjusted and fixed to a cistern, when the water is drawn off,
the float lever V, will drop to the position indicated by the dotted lines in Fig. 1,
where it is stopped by the lug L, coming in contact with the bar X, see Fig. 3.
This movement of the rod V, and consequent partial revolution of the nut K,
causes the valve to travel away from the diaphragm, and enables the water to
escape past it through the port D, to the outlet E. The reverse action is caused
by the rising of the ball or float, and the valve presses the diaphragm against the
annular seat B* and closes the tap.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is :-
=
1. A ball or float tap having its constituent parts constructed and arranged as
herein before described and substantially as illustrated in the annexed drawings.
2. In a ball or float tap the arrangement and combination of the frame H,
nut K, cap N, and horizontally moving valve P, for the purpose specified, and
substantially as shown.
3. In a ball or float tap, a valve rod provided with a quick screw thread, fitting
into a corresponding quick threaded nut to which the float lever is attached, in
combination with a movable cap or its equivalent, for adjusting the position of the
valve rod, substantially as hereinbefore described and for the purpose specified.
