Improvements in Self-closing, Waste and Drip Preventing Valves
for Drawing Off Beer or other Liquids.
I, GEORGE ADIE, of Bewick Road, Gateshead, in the County of Durham,
Manager, do hereby declare the nature of this invention to be as follows:-
My invention relates to a valve to be connected to the nozzle of a beer pump
or of a cock or branch of any barrel or other vessel from which the liquid is
required to be drawn without waste or drip.
The valve (preferably of deep mitre shape) enclosed in a case, closes and is kept
closed by the pressure of the liquid above it assisted it may be by being weighted
or having a spring so arranged as to operate to close it. The valve is guided into
and out of its seat by suitable guide spindles or bars working freely but accurately
in guides internal or external to the valve case and the lower spindle or bar will
have formed on or attached to its projecting end such a rim or portion of a rim as
will readily receive the rim of a glass or other vessel into which the liquid is
to be drawn. The upper spindle may be weighted or may have a spring inside or
outside the casing to ensure the valve closing instantly and perfectly in its seat
when the glass or other vessel is withdrawn. The valve case, valve and its
fittings may be made in metal or any alloy of metals or of any suitable substance
such as hard wood, ebonite, celluloid or any artificial composition which is cleanly
and will not be chemically affected by the liquid to be dealt with.
The operation is very simple, the barman or attendant pressing the glass or
other receptacle upward against the rim on the valve guide spindle or bar thereby
raises the valve when the liquid issues until the glass is withdrawn when the
valve instantly closes by the pressure of the liquid above it assisted or not by a
weight or by a spring and being preferably of a plug shape with moderate taper
will prevent waste by drip but I may use any other suitable form of valve. When
bottles are to be filled a funnel may be fitted in the bottle neck which will operate
io raise the valve by means of the rim on its lower spindle.

page_text: same is to be performed to be particularly described and ascertained in and by the
following statement:-
My invention relates to a valve to be connected to the "nozzle" of a beer
pump or of a cock or branch of any barrel or other vessel from which liquid is
required to be drawn without waste or drip.
The valve, preferably of deep "mitre" shape, enclosed in a case, closes and is
kept closed by the pressure of the liquid above it, assisted it may be by being
weighted or having a spring so arranged as to assist to close it. The valve is
guided into and out of its seat by an upper spindle working freely but accurately
in such guide in the valve case, and the lower spindle has formed on or attached
to its projecting end such a rim, or portion of a rim or crosspiece, as will readily
receive the rim of a glass or other vessel into which the liquid is to be drawn.
The upper spindle may be weighted or may have a spring inside or outside the
casing to ensure the valve closing instantly and perfectly in its seat when the
glass or other vessel is withdrawn. The valve case, valve, and its fittings may, be
made in metal or any alloy of metals or of any suitable substance such as hard
wood, ebonite, celluloid, or any artificial composition which is cleanly and will
not be chemically affected by the liquid to be dealt with.
The operation is very simple, the barman or attendant pressing the glass or
other receptacle upward against the projecting lower end of the valve spindle,
which raises the valve, when the liquor issues until the glass is withdrawn, when
the valve instantly closes by the pressure of the liquid above it, assisted or not by
a weight or by a spring, and, being of a mitre" plug shape with moderate taper,
will prevent waste by drip. Thus three, four, or more glasses held by the barman
in his hand are rapidly filled.
When bottles are to be filled a funnel may be fitted in the bottle neck which may
operate to raise the valve by pressing up the rim or crosspiece on its lower spindle.
In some cases, as for spirit or wine taps subject to corrosion by chemical
action of the liquor, I may supplement the tightness of the main valve by fitting
above it in a separate seat a check valve, opening when the main valve is raised
and closing independently of it after it has closed, thus preventing any drip
should the main valve not be quite tight.
DESCRIPTION OF DRAWINGS.
On the accompanying Sheet of Drawings, Fig. 1 shews a tap of full size for
beer or similar liquors, and Fig. 2 a tap also of full size adapted for spirits and
wines or the like, which may be fitted as shewn with a supplementary ball
valve, if required, or without which it is simply the same, of smaller size, as that
shewn by Fig. 1. The same letters indicate the same parts on both figs. where
such parts form the tap.
A is the case fitted with a screwed cover A¹ the horizontal branch A2, screwing
into the beer pump nozzle or direct to the cask as the case may be. In the case
is formed the seat A3 for the mitre" valve B, ground in so as to be an accurate
fit, and on the upper end of this valve is a spindle B' working freely in a guide on
the screwed cover. Below the valve is a spindle B2 projecting from the mouth of
the tap, the end of which B3 is bent to about a right angle, and with cross grooves
on its underside as shewn, or the end of 13 may be curved and covered with an
india rubber tube.
The barman having three, four, or more glasses in one hand, while he works
the pump with the other, places each glass in succession under the bar B3 and
presses upward opening the valve until the glass is filled, when he withdraws it
and the valve instantly closes until again opened by another glass. No weight.
nor spring, above the valve is here shewn, but if required, which I do not
anticipate the weight, or spring, may be either inside or outside the case as
will be readily understood.
Referring to the spirit tap, Fig. 2, A, is the case, A¹ the screwed cover, A³

page_text: the branch to the spirit cask, A3 the seat for the mitre valve B, and A' a nozzle
screwed on to the mouth of the tap for ready access to the interior; B¹ is a short
spindle projecting upward which may form a three winged guide (see plan below
Fig. 2 for the valve B, in the seat C, of the ball valve C. The check valve C¹
(in this case shewn as a ball valve) rolls about freely in its concave seat C, in
which it rests when closed as shewn, the dotted lines shewing both valves raised
and open.
In certain spirits and wines, for instance rum and port wine, corrosion is liable
to take place slowly of nearly all metals as copper, tin, or alloys of metals as gun
metal, and the main valve B, may get a little untight and it is in such a case
that I fit the supplementary check valve C¹ having the following actions.
When the barman opens the main valve B by pressing the glass or measure
against the end B3 of the lower spindle, the end of the upper spindle at the same
time pushes aside the ball valve from its seat, and the liquor flows from the cask
into the measure until it is removed, when the main valve instantly closes and the
ball valve rolls into its seat. If now the main valve should not be quite tight
against drip the ball valve in its seat shuts off the liquor when no drip can pass
the main valve, because a vacuum would be formed in the space * between the
two valves then filled with the liquor. When the supplementary check valve is
not required the construction of the spirit tap is the same as the beer tap,
provided that some material or substance may be found which will resist corrosion
by spirits or wines and sufficiently hard and otherwise suitable. Although a ball
valve is very simple in its action I may fit another form of check valve as a
mitre or flat faced closing by a spring and opened by pressing down the spring
with the thumb.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:--
1st. The improvements in self closing waste and drip preventing valves,
beer or ordinary liquors, consisting of a valve, preferably of mitre form, working
and accurately guided in a seat formed with or fitted in the valve casing opened
by the glass or other vessel being pressed upward against the valve and closing
automatically by pressure of the liquid above it, assisted or not by springs or
weights; substantially as described and shewn by Fig. 1.
2nd. The improvements in self closing waste and drip preventing valves,
opened by the glass or other vessel being pressed upward against the valve and
closed automatically by pressure of the liquid above it, for spirits, wines, or
other liquors, having corroding action, consisting in fitting above the main valve
a supplementary check valve in such manner that should any leakage take place
in the main valve the check valve will take it up; substantially as described and
shewn by Fig. 2.
