Improvements in or connected with Taps for Drawing off Liquids.
I, EDWARD GEORGE WHITEHEAD, of Mosterton, 15, Brunswick Road, Kingston
Hill, Surrey, Company Director, do hereby declare the nature of this invention
to be as follows:-
--
The object of this invention is to fit an appliance to the nozzle of a tap that by
the upward pressure of, say, the mouth of a bottle, a valve can be lifted or dis-
placed and the liquid allowed to flow freely until the pressure of the bottle mouth
is removed, when the valve will close again and effectually stop the flow withoui
any drip or waste.
For the purpose of my invention, I attach to the nozzle of a tap, by screwing or
otherwise, an extension consisting of a valve chamber and a short tube, another tube
is loosely fitted within the extension tube in such manner that on pressure of, say,
a bottle mouth being applied against a flange on a turned up or return portion of
the loose tube outside the extension, a valve (ball or other) will be lifted or
removed by the upper end of the inner loose tube and the liquid be allowed to
flow into the bottle or other receptacle, the normal pressure of the liquid being
sufficient to close the valve again on removal or withdrawal of the bottle mouth.
The loose fitting tube may be secured from falling out of the extension by a
sliding or other clip, or by enlarging flaring" its upper inner portion within
the valve chamber.

I, EDWARD GEORGE WHITEHEAD, of Mosterton, 15, Brunswick Road, Kingston
Hill, Surrey, Company Director, 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 fit an appliance to the nozzle of a tap that by

page_text: the upward pressure of, say, the mouth of a bottle, a valve can be lifted or dis-
placed and the liquid allowed to flow freely until the pressure of the bottle mouth
is removed, when the valve will close again and effectually stop the flow without
any drip or waste.
For the purpose of my invention, I attach to the nozzle of a tap, by screwing or
otherwise, an extension consisting of a valve chamber and a short tube, another tube
is loosely fitted within the extension tube in such manner that on pressure of, say,
a bottle mouth being applied against a flange on a turned up or return portion of
the loose tube outside the extension, a valve (ball or other) will be lifted or
removed by the upper end of the inner loose tube and the liquid be allowed to
flow into the bottle or other receptacle the normal pressure of the liquid being
sufficient to close the valve again on removal or withdrawal of the bottle mouth.
The loose fitting tube may be secured from falling out of the extension by a
sliding or other clip, or by enlarging or "flaring" its upper inner portion within
the valve chamber.
My invention is clearly represented on the annexed sheet of drawings.
Figure 1 sectional view of the apparatus herein before referred to.
Figure 1 clevation of screw down draw off tap of the ordinary kind with its
outlet nozzle screw threaded and having, as shown in section, my valve appliance
screwed thereto, the valve being on its seating and the liquid from the tap shut
off by my valve of globular shape.
Figure 2 is a similar elevation of an ordinary plug tap and having my new
valve appliance affixed to the outlet nozzle indicated in section, the valve in this
instance being of conical shape to fit a conical ground seating, the passage of the
liquid being shut off by my new valve appliance.
Figure 3 shows the outlet nozzle of an ordinary tap with my valve appliance
affixed and in section, the valve being lifted off its seat by a bottle neck bearing
upwardly against the prongs which project from my valve.
It will be clearly understood although I have shown screw thread attachments
of my valve appliance to screw down in those figures, there are other ways of
effecting the connection, such as by a rubber washer, a short length of rubber
tubing, a sliding ferrule, a clip ring, or any other means and such as an ordinary
mechanic would adopt for the purpose of permanently or temporarily connecting
my valve appliance to the outlet nozzle of a tap.
Figure 4 is a front elevation of a series of my valve appliances fitted to nozzles
of a branch pipe in order that a number of bottles can be filled at the same time
or otherwise as desired, such as in a factory where bottles are charged with
liquids for trade distribution to the public, such as liquid or fluid sauces, extracts
of coffee, extracts of meats, bottled wines, beers, and other liquids, such as liquid
scents and perfumes where exact quantities are of importance, there being as a
rule no after drip from my valve appliance because of the shutting off being equal
and simultaneously all over the face of the valve and not by gradual closing, as
with screw down and plug taps in general use and to which my invention is
applicable, the pressure of the head of water being sufficient to keep the valve
tight.
The valve may be packed or have a washer or other closing media but as a rule
I have found a well ground valve and a well ground seating perfectly watertight
when in contact.
Referring to Figure 1, the outlet nozzle A. of the tap B is screwed on the
outside for the reception of thimble or sleeve C which is screw threaded inwardly
down to a shoulder D just below which a neck E is formed of smaller diameter
with an edge seating for the sphere F to rest upon as the closing medium.
The neck E contains for a greater part of its length, a tube G which is arranged
by the pins and slots H to have a limited movement. The lower end of the tube G
has a ring shaped base I extending outwardly and an uprising wall J from which
is a flange K for the neck L of a bottle M to be pressed against when the valve F
has to be lifted for the bottle to be charged.

page_text: The act of lifting the bottle when in contact with the flange K opens the passage
and the downward movement of the bottle permits of the self closing.
According to Figures 2 and 3 which is a modification, the tube G is dispensed
with and the neck E of the ferrule sleeve or socket C contains a valve F on wings P
which serve as guides for the vertical action of the valve F which is here shown of
cone shape.
The sphere and the cone shaped valves are preferable for my purpose but other
shape of valves for certain uses may be made available and as part of my said
invention.
At Figure 2, appliance valve closed, and Figure 3, appliance valve open, the
wings P, P, have a depending wire Q from which a cross bar R extends with
uprising portions S and arms T, which latter correspond for action to the parts
of Figure 1 marked I, J, K, and give more vent while the bottle M is being
charged.
It will be observed, a slight difference is shown in the method of securing the
sleeve E to the tap nozzle A. At Figure 2, the tap nozzle has a collar or ring U
brazed or soldered on it and screw threaded on the inside for engaging an outside
screw threaded sleeve or ferrule E, while at Figure 3, the tap nozzle is screw
threaded on the inside for the reception of the outer screw thread of the ferrule.
Figure 4 is an example of a series of my last named valve appliances in con-
nection with nozzles V of a branch W from a supply X connected to all the outlets
and need no further description for it to be understood.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
1. An internal valved appliance affixable to an ordinary liquid draw off tap,
the appliance being constructed and arranged in the manner and for the purposes
herein before explained and substantially as represented in the annexed drawings.
2. The particular arrangement and combination of apparatus affixable by screw
or other connection to an ordinary draw off tap, as represented at Figure 1^ of the_
annexed drawings.
3. The particular arrangement and combination of apparatus affixable to the
nozzle of an ordinary draw off tap, as represented at Figures 2 and 3 of the
annexed drawings and in which the tube G of Figure 1 is dispensed with, as
set forth.
