Improved Valve Action for Bib, Ball and other Valves for Liquids.
I, ALFRED PRIEST, Sanitary Inspector, of 22, Batsford Road, St. John's, London,
S.E., do hereby declare the nature of this invention to be as follows:-
The object of this invention is to apply to bib, ball and other valves for liquids
an action which will dispense with the necessity for the use of seatings and washers,
thus obviating the crushing and tearing action consequent upon the washers
impinging upon their seatings, and incidentally lessening the strain upon the
other working parts. The invention consists in the following arrangement:-
A chamber having two sections, one section being plain and circular, the other
section being circular, with slots, or recesses running longitudinally. In this
chamber is fitted a cup shaped collar which may be made of leather or other
suitable material. This collar is attached to a spindle in such a manner that it
can be moved backwards or forwards in the chamber.
The action is as follows:-
When the valve is closed, the cup shaped collar is made to rest in the plain
circular portion of the chamber, the rim of the cup being placed to face the pressure
of the liquid expands, making a perfect seal through which no liquid can pass.
When the valve is to be opened the collar is moved into that portion of the
chamber provided with slots or recesses the liquid can then flow through the
slots, or recesses past the cup shaped collar.
Improved Valve Action for Bib, Ball and other Valves for Liquids.
I, ALFRED PRIEST, of 22, Batsford Road, St. John's, S.E., Sanitary Inspector,
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:-
'
The object of this invention, is to apply a new device to bib, ball and other
valves for liquids; which will dispense with seatings and washers, thus obviating
the crushing and tearing action consequent upon the washers being forced upon
their seatings, and incidentally lessening the strain upon other working parts
of the valves.
This valve action by reason of being self closing will in the case of the screw
slipping in the bib valve, or the ball being broken from the ball lever in the
ball valve, instantly close, stopping the flow of the liquid.

page_text: Referring to the accompanying figures:
Figure 1 is a section of the new device applied to a bib valve. Figure 2 is a
section of the new device applied to a ball valve. Figure 3 is a section of the
chamber with slots or recesses. Figure 4 shews the cup shaped collar attached to
portion of valve spindle.
A is a plain circular chamber.
B is a circular chamber, having slots or recesses running longitudinally.
C is a cup shaped collar.
D) is the valve spindle.
E are the longitudinal slots or recesses.
F is a metal rim to prevent the cup shaped collar C from being cut. This
rim may in some cases be dispensed with.
G is the screw spindle, and G¹ ball lever.
The action as follows:-
When the cup shaped collar rests in the plain circular chamber A as shewn in
Figure 2 the pressure of water causes the collar C to expand making a perfect seal.
When the valve is required to be opened, the valve spindle D is by means of
the screw spindle G or the ball lever G¹ thrust forward causing the cup shaped
collar C to rest in the chamber B provided with slots or recesses, as shewn in
Figure 1. The liquid can now flow through the slots or recesses E by the side
of the cup shaped collar C to the outlet of valve.
This device may be applied to other kinds of valves, by adapting the means of
moving the valve spindle to the exingences of the cases.
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. A cup shaped collar fitted to valve spindle so constructed and arranged as to
rest in a plain circular chamber when valve is closed.
2. A chamber provided with longitudinal slots in which a cup shaped collar is
so constructed and arranged to rest when valve is open.
3. A valve action consisting of two chambers, one circular and plain the other
circular, but having slots or recesses running longitudinally. A valve spindle with
cup shaped collar attached, arranged in such a manner that it can be moved
backwards and forwards, causing the cup shaped collar to rest in either of the
above-mentioned chambers as described and set forth.
