ALBERT WILLIAM KING 2 Cornfield Terrace Eastbourne Sussex do hereby
declare the nature of this invention to be as follows:-
I use the pressure of water to assist in closing valve which prevents leakage.
This invention has for its object improvements in ball bib and other cocks and
I will now proceed to describe my invention with reference to the accom-
valves.

COMPLETE SPECIFICATION.
Improved High-pressure Valve-tap.
I ALBERT WILLIAM KING of 2 Cornfield Terrace, Eastbourne Sussex 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 improvements in ball, bib and other valve cocks in
which the pressure of fluid assists in closing the valve.
In the accompanying drawings
Figure 1 is an elevation of a bib valve cock.
Figure 2 is a sectional elevation of Figure 1.
Figure 3 is a sectional elevation of part of Figure 2 showing a modified form of
valve.
Figure 4 is a sectional elevation, the same as Figure 3 the valve being open
instead of closed.
Figure 5 is a sectional elevation of a bib valve cock the valve of which is
operated by a ring lever.
Figure 6 is a sectional elevation of the upper part of Figure 5 taken at right
angles.
A is the body of the valve cock. B is the valve, and C the seating upon
which the valve rests to close the outlet D and in contact with which it is urged by
Price 6d. A

page_text: the fluid pressure admitted at the inlet E. The valve is driven from its seating by
means of a handle F, a quarter revolution of which causes the valve to be suffi-
ciently lifted or dropped according to the direction in which the handle moves in
the inclined slot G shown in Figure 1.. When the valve B is open the fluid
passes from above the valve seating C by way of lateral openings a a¹ all
admitting the fluid to the central tubular part of the valve which constitutes
the outlet D. As the valve becomes worn in its tubular guide the fluid may in
appreciable quantity pass down outside instead of inside the tubular part of the
valve and so escape at the inclined slot G. In order to avoid this I provide a
spring clip H which rotates together with the handle F and so outwardly
covers the inclined slot G so as to avoid any escape of fluid in the manner
referred to.
In Figures 3 and 4 the modified form of the valve B is designed with the
object of rendering the spring clip H, which covers the inclined slot G externally,
unnecessary.
A
The valve seat C is formed with a depending tubular part M to telescope into the
central tubular part of the valve B. Thus a shield is formed internally which
prevents the escape of liquid at the inclined slot G when the valve is open.
In all the figures I have shown a conical valve-seating, closed by a conical valve
but the valve may be of globular form, or a valve of elastic material closing
upon a flat seating may also in some cases be substituted for the conical or globular
valve.
In order to avoid concussion in the pipes by suddenly closing the valve BI pro-
vide a cavity in the body of the cock A in which an india rubber ball J may be
retained forming an air cushion combining the elasticity of the india rubber ball
with the elasticity of the air confined therein and ensuring the non absorption of
the air by the fluid passing in contact therewith.
If the valve is to be operated by means of a ring lever K as shown in Figures 5
and 6 provide a diaphragm L to separate the waterway from the spring box and
I mount the chamber to receive the india rubber ball J upon the valve stem B
through which I make a channel to establish a communication between the fluid
behind the closed valve and the chamber which contains the india rubber ball J
to constitute a permanent air and india rubber cushion as herein before described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In a valve cock, an inclined slot in the outer casing of the valve to impart a
vertical movement to the valve by rotating a handle connected with the valve and
projecting through the slot substantially as described by reference to Figures 1, 2, 3
and 4 of the accompanying drawings.
2. In combination with a valve cock a cushion consisting of an india rubber ball
containing air confined therein, the ball being situated in the waterway or in a
chamber communicating with the waterway as and for the purpose described with
reference to Figures 2, 5, and 6 of the accompanying drawings.
Dated this 25th day of November 1890.
