We JOHN SYKES of Square Hill, Weaver, and THOMAS COOк of Field Terrace,
Clerk, both of Kirkheaton near Huddersfield in the County of York, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to an improved form of tap or valve, in which a ball fitting
into a seating is employed in place of the conical plug or valve and socket ordinarily
in use, and in which the plug or valve frequently requires refitting and grinding or
new leather washers are required to prevent leakage.
To carry out our invention we form upon or in connection with the tap a chamber
which has about twice the transverse sectional area of the ball to be employed, and
the diameter of the ball is regulated according to the area of the outlet of the tap.
At the outlet end of this chamber is formed a seating into which the ball hereinbefore
referred to, is forced by means of a screw, spring or lever, and partly by the pressure
of the water. The ball can be forced out of the seating back into the chamber
to allow the water to flow, the chamber being sufficiently large to allow the ball to be
forced back as far as may be required.
The rod or spindle which actuates and adjusts the ball may have a screw thread
formed upon it, and by preference passes through the front of the tap, and terminates
in a handle for convenience of operation.
A screw plug at the top of the chamber affords access to the ball and the inside of
the chamber.
The rod or spindle is screwed or fixed into the ball, and when the ball becomes
worn the rod or spindle is unscrewed and fixed in a fresh position, so as to present a
fresh and unworn surface of the ball to the seating or socket when in position to
close the outlet of the tap.
Dated this Twenty second day of March 1888.

page_text: We JOHN SYKES of Square Hill, Weaver, and THOMAS COOK of Field Terrace,
Clerk, both of Kirkheaton near Huddersfield, in; the County of York, 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
Our invention relates to an improved form of, tap or valve, in which a ball fitting
into a seat or shoulder is employed, in place of the conical plug or valve, fitting into
a tapering barrel or socket, ordinarily in use, and in which. the plug or valve,frequently
requires re-fitting and grinding, or re-covering with a new leather washer to
prevent leakage.
To carry out, our invention we form in the body of the tap or valve a chamber,
within which the ball operates, and towards the outlet of the chamber is formed
a shoulder or cupped seat, into which the ball fits closely when the tap or valve is
closed. The ball, is held in position, when the, tap or valve, is, closed,, partly, by
means of an adjusting screw fixed to the ball and, operated by means of a thumb. piece,
handle, or hand-wheel, and partly, by, the pressure of the water.
In order to open the tap or valve, the ball is forced back out of the cupped, seat by
means of the adjusting screw herein before referred to.
'
The ball is.by, preference, made of vulcanized indiarubber, and is secured to the end
of the adjusting screw, by means of a nut, to, which access, may be had, for putting on
a fresh, ball,, or for other, purposes, by removing a screw, cap.or plug..
In order to enable our invention to be fully understood,, we will proceed to, describe
the same with reference to the accompanying, drawings, in, which,
Figure 1 represents a,, sectional elevation of a domestic, water tap, to which our
improvements are applied.
Figure 2. represents a sectional, plan of a portion of Figure 1 at the line A. B.
Figure 3, represents a sectional elevation of a water,.,valve, to which our improve-
ments are applied. Similar letters refer to similar parts, in each figure.
The chainber in, which the ball, operates is represented at UC, and the shoulder or
seat against which the ball K presses, when the tap or valve is closed, at P P.
The ball K is, secured, upon the. spindle J, which is a continuation of the adjusting
screw H, by means of the nut L. The screw cap M is removed to afford access to the
..ball; K, or to the interior of the chamber.C..
The upper part of the adjusting screw H is connected by means of the spindle, G
with the thumb-piece or hand-wheel F. The screw gland N, with the packing O,
prevent leakage round the spindle G. The outlet. of the tap or-valve is represented
at D, and the inlet at E:
.
In Figures 1 and 3 the, ball K is represented as being in its seat P, and the tap or
valve thereby closed, and, in the same two figures the dotted lines represent the ball
forced out of its seat, the tap or valve being thereby opened.

page_text: In figure 2 grooves are indicated at bb, which are formed in the sides of the
chamber CC, which grooves allow water to escape from below the ball, when the tap
or valve is being opened.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what 'wo
claim is :
1. In a water tap or valve the general arrangement of the various parts, formed
and operating substantially in the manner described and represented in the accom-
panying drawings.
2. In a water tap or valve the combination of the adjusting scrow H, the ball K
fitting into the seat P P, the nut L, and the screw cap or plug M, all constructed and
operating in the manner, and for the purposes described, and as represented in the
accompanying drawings.
