PROVISIONAL SPECIFICATION.
An Improved Automatic Valve for Liquid Delivery Nozzles.
I, FREDERICK ABRAHAM POUPARD of Cambrian House, West Norwood, in
the County of Surrey, Gentleman, do hereby declare the nature of this invention
to be as follows :—
My invention relates to liquid delivery nozzles such as the nozzles for beer pull
engines, the delivery pipes or nozzles of spirit casks or containing vessels, or the
nozzles of other vessels from which a constant recurrent delivery of certain portions
of liquid is required, and consists of the adaptation to such delivery nozzles of an
automatic valve, which shall be opened by the application thereto of the glass or
vessel into which the liquid is to be delivered, and which automatically closes
liquid-tight on the removal of the said glass or vessel, thus saving any drip or
waste.
The proportion of waste beers or spirits that takes place in bars by the drip of
the liquid remaining in the delivery nozzle between the tap or plunger and the end
of the nozzle is very considerable, and it is this waste that I seek to avoid by my
improved appliance; and further, by dispensing with an ordinary tap, to save the
time for delivery of spirits or other liquids by obviating the necessity for the
constant use of such tap.
To carry my invention into effect I apply to a beer or spirit delivery nozzle an
additional chamber containing a valve of any suitable description, which lies by its
weight upon a seating, and thus automatically closes the outlet. The weight or
pressure of the liquid behind the valve only serves to press the valve more firmly
on its seat.
To the end of this valve chamber I apply a loose sleeve, provided with an
external horn or flange, against which the glass or vessel to receive the discharge
of liquid is pressed upwards.
The loose sleeve is provided with a spindle entering the valve chamber through
the seating, and under the valve, thus raising the valve from the seating and
opening the delivery nozzle, when the glass or vessel is pressed under the sleeve
flange or lug.
The spindle of the sliding sleeve may be attached to the valve, and continue
through it as a guiding spindle, or the valve may be a ball, or of other convenient
shape, and be merely lifted from its seat, by the lifting spindle of the sliding sleeve.

COMPLETE SPECIFICATION.
An Improved Automatic Valve for Liquid Delivery Nozzles.
I, FREDERICK ABRAHAM POUPARD, of Cambrian House, West Norwood, in
the County of Surrey, Gentleman, 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:-
My invention relates to liquid delivery nozzles, such as the nozzles for beer
pull engines, the delivery pipes or nozzles of spirit casks, or containing vessels,

page_text: or the nozzles of other vessels from which a constant recurrent delivery of
certain portions of liquid is required; and consists of the adaptation to such
delivery nozzles of an automatic valve, which shall be opened by the application
thereto of the glass or vessel into which the liquid is to be delivered, and which
automatically closes liquid-tight, on the removal of the said glass or vessel, thus
saving any drip or waste.
The proportion of waste beers or spirits that takes place in bars by the drip
of the liquid remaining in the delivery nozzle between the tap or plunger, and
the end of the nozzle, is very considerable, and it is this waste that I seek to
avoid by my improved appliance, and further, by dispensing with an ordinary
tap, to save the time for delivery of spirits or other liquids by obviating the
necessity for the constant use of such tap.
To carry my invention into effect I apply to a beer or spirit delivery nozzle
an additional chamber, containing a valve of any suitable description, which lies
by its weight upon a seating, and thus automatically closes the outlet. The
weight or pressure of the liquid behind the valve only serves to press the valve
more firmly on its seat.
To the end of this valve chamber, I apply a loose sleeve, provided with an
external horn or flange, against which the glass or vessel to receive the discharge
of liquid is pressed upwards.
The loose sleeve may be provided with a spindle entering the valve chamber
through the seating and under the valve, thus raising the valve from the seating,
and opening the delivery nozzle, when the glass or vessel is pressed under the
sleeve, flange, or lug.
Or, the spindle of the sliding sleeve may be attached to the valve, and
continue through it, as a guiding spindle, or the valve may be a ball, or of other
convenient shape, and be merely lifted from its seat by the lifting spindle of
the sliding sleeve.
And in order that my invention may be the better understood, I now proceed
to describe the same in relation to the drawings hereto annexed, and to the letters
and figures marked thereon.
Figure 1 is a sectional elevation of a beer tap or nozzle fitted with my improved
valve.
Figure 2 is an end view of the same.
Figure 3 is a view, showing means for keeping the valve open, when a con-
tinuous flow of liquid is required.
Figure 4 is a modified form of the same.
Though a beer nozzle is shown above for convenience, fitted with my valve,
it is obvious that the valve may be fitted to any tap or nozzle for beer, wines,
or spirits, or any liquid, from which recurrent deliveries are required.
To the end of the nozzle A. I fit an additional chamber B, containing a valvę C,
which lies by its weight upon the seating D.
This valve may be of any suitable form such as a mushroom, ball, or flap
valve.
To the exterior of the valve chamber B I apply a loose sleeve E, provided with
external horns F, preferably covered with india-rubber, or an equivalent flange,
against which the glass or vessel to receive the discharge of liquid is pressed
upwards, and a back rest H.
This loose sleeve is connected by a pin G to the spindle of the valve C, or is
provided with a spindle which may enter upwards through the seating D to lift the
valve, when the latter is in the form of a ball, or flap, and has no spindle.
When the glass or receiving vessel is pressed upwards towards the tap, so that
the rim of the glass or vessel presses upwards upon the horns F or equivalent
flange, the valve is lifted from its seat against the liquid pressure, and the liquid
flows into the glass or vessel, and upon removal of the glass or vessel the valve
drops automatically upon its seating, and stops the flow of liquid instantaneously,
without the use of any other tap.

page_text: I fix a pin J upon the valve chamber B projecting laterally outwards, which can
engage with a slot K in the loose sleeve E to prevent the rotation of the loose
sleeve E to which the horns F and back rest H are attached, so that they are
always in the proper position to receive the glass or vessel.
In Figure 3 I show an arrangement whereby the valve may be kept in its opened
position to allow a continuous flow of liquid. To effect this I arrange a slot L
extending laterally from the slot K and in the slot L I provide a recess M.
By
turning the loose sleeve E round a small amount, when in its upper position, the pin J
travels along the slot L and can engage in the recess M and thus maintain the
valve in the open position.
I provide a spring N or other equivalent device which normally stands over the
open end of the slot L to prevent the entry of the pin J into it, when intermittent
discharge of liquid- is being effected. When the valve is to be maintained in the
open position, the sleeve E is turned, so that the pin J presses the spring N back-
ward, and allows of the engagement of the pin J in the recess M.
In Figure 41 show a modification of this arrangement, doing away with the
spring, and arranging an inclined surface at the mouth of the slot L, so that, should
the sleeve E be moved about its axis, and the pin J not be exactly under the
slot K, the inclined plane will, on the sleeve dropping, guide the pin J in the
slot K..
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1st. An automatic valve in combination with any wine, beer, spirit or other
delivery nozzles or tap, and provided with a projecting horn, horns, or equivalent
flange, so that it may be lifted from its seat in said nozzle by application of a
receiving glass or vessel thereto, and close the nozzle automatically upon the
removal of said glass or vessel.
2nd. The combination with a nozzle or tap for the delivery of a liquid, of an
auxiliary chamber, containing a valve and seating, and provided with an external
sliding sleeve, fitted with a horn, horns, or flange, and connected to the spindle of.
said valve, or provided with an axial spindle to operate the said valve upon the
approach of a receiving glass or vessel.
3rd. In an automatic valve for controlling delivery of a liquid from a nozzle, a
sliding sleeve upon the valve chamber striking and lifting the said valve, having a
bayonet slot joint, with or without a spring, in combination with a fixed pin on the
valve chamber to enable the said sleeve and valve to be permanently held up from
the seating when required, substantially as described.
4th. The arrangement and construction of an automatic valve and containing
chamber, fitted to a nozzle or tap for the delivery of a liquid, and provided with
means for operation by the approach to the nozzle of a receiving glass or vessel,
substantially as described and illustrated herein.
Dated this 8th day of December 1893.
