PROVISIONAL SPECIFICATION.
Improved Means or Device in connection with Beer Engine Nozzles
or Liquid Taps for Preventing Waste.
ALFRED GEORGE THATCHER of 52 Abinger Road Deptford, London
Pewterer do hereby declare the nature of my invention to be as follows
-
The object of my invention is an appliance or valve to be fitted to, or form a
part of the delivery nozzle of a beer engine or a tap from which spirits or other
liquid is drawn in order to prevent waste.
'When beer or liquid is drawn from a beer engine on tap, there usually remains
a small quantity of liquid in the spout after the engine pull has been released or
the tap turned off, and this small quantity generally escapes and is wasted, unless
the person drawing the liquid stops a short while afterwards to receive it in the
glass or measure.
Various devices have been tried to obvinte this source of waste, those chiefly
depending upon the action of springs or other moving parts which were easily
liable to get out of order, and have consequently proved ineffective in practice.
The valve employ has no moving parts, and is fixed and constructed as
follows
I suspend a flanged disc or bell within the delivery nozzle or spout by means of
a threaded stem, screwed into the thickness of metal of the upper side of the nozzle,
which may be formed with a shoulder for its reception The flange of this disc
or bell dips into a cup with a raised central delivery office the two parts forming
a trap valve in such manner that after beer or other liquid is drawn off a seal of
the liquid is formed in the trap which stops the passage of air up into the nozzle
and prevents the escape of the liquid remaining in the spout.
The flanged disc or bell has a small central pin or post projecting downwards
into the raised central delivery orifice of the cup in order to prevent any spraying
of the liquid when passing through the trap valve.
The nozzle may be slightly enlarged or bulb shaped at the delivery end where
the valve is located and the cup portion of the trap with the lower end of the
nozzle is detachable by unscrewing for ready access, for cleaning.
It will be seen that in my waste preventer there are no springs or other moving
parts and it is consequently simple and practical in its working.

Improved Means or Device in connection with Beer Engine Nozzles
or Liquid Taps for Preventing Waste.
I, ALFRED GEORGE THATCHER of 52 Abinger Road Deptford London
Pewterer, do hereby declare the nature of my invention to be as follows:-
The object of my invention is an appliance or valve to be fitted to, or form a
[Price 8d 1

page_text: part of the delivery nozzle of a beer engine or a tap from which spurts or other
liquid is drawn in order to prevent waste
When been or liquid is drawn from a beer engine or tap there usually remains &
small quantity of liquid in the spout after the engine pull has been released or the
tap turned off, and this small quantity generally escapes and 18 wasted; unless the
person drawing the liquid stops a short while afterwards to receive it in the glass
or measure.
Various devices have been tried to obviate this source of waste, those chiefly
depending upon the motion of springs or other moving parts which were easily
liable to get out of order, and have consequently proved ineffective in practice.
The valve I employ and which is shown in the annexed drawing has no moving
parts, and is fixed and constructed as follows:-
Within the delivery nozzle oi spout A. I suspend a flanged dise or bell B. by
means of a threaded stem C screwed into the thickness of metal of the upper side
of the nozzle which may be formed with a shoulder D for its reception. The flange
of this disc or bell dips into a cup E. with a raised central delivery orifice F. the
two parts forming a trap valve, in such manner that after beer or other liquid is
drawn off, a seal of the liquid is formed in the trap (as shown) which stops the
passage of air up into the nozzle and prevents the escape of the liquid remaining in
the spout which would otherwise dup away or
$6 weep."
The flanged disc o bell B may have in some cases a small central pin or post
projecting downwards into the raised central delivery office of the cup in order
to prevent any spraying of the liquid when passing through the trap valve.
The nozzle is slightly enlarged or bulb shaped at the delivery end where the
valve is located, this bulb or iounded shape being a useful feature, as it avoids
the sharp edge common to the ordinary spout which often comes in contact with the
edge of a glass or a jug when being placed under it and causes it to be fractured
or chipped.
The rounded nose is also more convenient for bottles.
The cup portion of the tiap with the lower end of the nozzle is formed as a
separate piece and may be detachable by unscrewing (if desued) for ready access
foi cleaning.
It will be seen that in my waste preventer there are no springs or other moving
parts and it is consequently simple and practical in its working.
Ilaving 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
The improved means or device in connection with beer engine nozzles or liquid
taps as described and substantially as shown for the purpose set forth.
Dated this 22nd December 1894.
