I, JAMES HENRY AUSTIN of 48, Gutter Lane, in the City and County of London,
Manufacturers' Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved water tap or valve and it consists
essentially of a double valve adapted to be opened by a simple lifting action and
to be closed by the pressure of the water without the use of springs or other
equivalent devices, the object being to obtain a tap which has a minimum number
of wearing parts and which will not readily get out of order by constant use.
According to my invention I mount in the delivery part of the tap a simple
disc valve carried by a spindle which passes out of the casing of the tap through
a suitable stuffing box and which is provided with a knob or its equivalent whereby
it may be lifted direct or with a lever whereby it may be lifted by leverage.
Above this valve in an independent chamber preferably located at right angles
to the delivery part of the tap is another valve chamber having a seating adapted
to be closed by a hinged flap valve. This flap valve is connected to the disc valve
by a suitable connection so that both are lifted from their seats at the same time,
sufficient play being allowed in the connection to allow of both valves obtaining
an independent seating on their seats.
The chamber of the flap valve is of such a size that when the valve is open
there is sufficient space around it for the water to flow past it, but the area of
the valve with respect to the area of the passage surrounding it is such that when
the lifting spindle is released the pressure of water acting on the said valve closes
it tightly on its seating and allows the disc valve to also drop on its seating and
so provide a secondary valve which prevents the escape of any water which may
leak past the flap valve.
Instead of using a stuffing box for the passage of the spindle carrying the
disc valve out of the casing a small disc valve may be mounted on the spindle
outside the casing for the purpose of sealing the hole through which the said
spindle passes. This auxiliary disc valve is preferably enclosed by means of a
suitable cap.

page_text: I, JAMES HENRY AUSTIN, of 48, Gutter Lane, in the County of London,
Manufacturer's Agent, 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 make a tap or cock for steam, water or other
liquids which will be self closing when not in use and which will not leak.
The invention consists in making a tap or cock with valves which close by
the pressure of the water or steam and so prevent the waste frequently caused
by the tap not being turned off, or insufficiently turned off. The tap is opened by
means of a suitable lever or other similar arrangement. as shown further on.
The tap is constructed with a chamber at the inrush side and is provided with
a valve at the outlet side of this chamber.
To this valve is connected by a short rod, or rods, a second and lower valve placed
at the bottom of a lower chamber near to the outlet of the tap.
These valves may be of any suitable size, shape, or kind, preferably the valve
in the first chamber is flat, with india rubber, leather or other kind of washer,
and works on a hinge, and that in he lower one is a drop bevelled valve. In
the case of the drop valve suitable slides or guides are fitted to the valve to ensure
its dropping accurately upon its seating.
To open the tap, a lever is fitted near the outlet of the tap, and preferably with
its fulcrum at the back of the outlet.
To this lever is fitted a tube made to telescope in the outlet of the tap, this tube
is sufficiently long to reach the lower valve in the tap, or to reach short legs or
struts with which the lower valve may be provided and to raise this valve to allow
the passage of the water.
The tube may be a single tube, or of a double, or U section and may be perforated
if desired.
The action of raising the lower valve also opens the upper valve by means of a
short rod thus allowing a passage for the water through the tap.
When the lever is released both the valves close owing to the pressure of the
water behind them. The end of the lever may be weighted if desired.
I will now describe my invention with reference to the accompanying drawings.
Fig. 1 shows a section of my improved tap or cock a portion of the lever being
shown in dotted lines. Fig. 2 is a separate drawing of the lever of the tap.
In Fig. 1a represents the chamber at the inrush side of the tap, and b, the
second or lower chamber; c is the upper valve hinged at d; e is the lower valve
fitted with slide e', and the legs or struts e, f is the rod connecting the two valves,
g is the lever (see also Fig. 2), fulcrumed at h, behind the outlet of the tap; j is
a double telescopic tube perforated at the bottom, and fitted to the lever g, by
means of the pins A, working in the slots (see also Fig. 2), l is a leather or india
rubber ring which may be used if found necessary.
It will be seen that both valves are so placed as to close by gravitation even if
there be no water to press them down, and also that they are so guided and directed
by hinges, rods, legs or other devices as to ensure their falling accurately into their
seats.
It is believed that this arrangement and combination of valves is absolutely
novel, and that the method of opening the tap by means of the lever and telescopic
tube from below is new in principle and effectually prevents splashing and
waste.

page_text: 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 tap or cock for steam, water and other liquids the combination of two
successive chambers each containing similar or dis-similar valves, said valves
being connected to each other by means of a rod or link so fitted and adjusted as
to cause the valves to work together, and to open by lifting a hinged lever operated
from below, and to close by gravity or by the pressure of the fluid when the lever
is no longer lifted, and with or without a tubular sliding piece, or equivalent
device, as herein described and set forth.
