A New or Improved Means or Apparatus for Preventing Air getting
to Beer, Wines, Spirits and other Liquids when being Drawn from
Casks, Barrels and the like.
I, MAX GIESSMANN, of 46, Broomhouse Road, Fulham, S.W., Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a new or improved means or apparatus for the pre-
vention of air getting to beer, wines, spirits and other liquids when being drawn
from casks, barrels and the like.
It is well known that when beer or other liquid has to be drawn that the spile
of the barrel has to be withdrawn to allow of the liquid freely passing through
the tap which causes the beer or other liquid to become flat or sour as the case may
be and a certain quantity to be wasted.
In carrying my invention into practice, I have an air chamber or bag of any
suitable shape form or size which I construct preferably of canvas or other suit-
able material or substance. Such air chamber or bag is provided with a suitable
nozzle opening of the same material. The bag or air chamber placed in the barrel
is deflated when the spile of the barrel is in its proper position and the cask is
full, but when the spile is withdrawn the air passing through the aperture into
the bag or air chamber causes it to become inflated and occupy the space left vacant
by the liquid drawn off.

A New or Improved Means or Apparatus for Preventing Air getting
to Beer, Wines, Spirits and other Liquids when being Drawn from
Casks, Barrels and the like.
I, MAX GIESSMANN, of 46, Broomhouse Road, Fulham, S.W., Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
ment:.
This invention relates to a new or improved means or apparatus for the pre-
vention of air getting to beer, wines, spirits and other liquids when being drawn
from casks, barrels and the like.

page_text: It is well known that when beer or other liquid has to be drawn that the spile
of the barrel has to be withdrawn to allow of the liquid freely passing through
the tap which causes the beer or other liquid to become flat or sour as the case may
be and a certain quantity to be wasted.
In carrying my invention into practice I have an air chamber or bag of any
suitable shape form or size which I construct preferably of canvas or other suit-
able material or substance. Such air chamber or bag is provided with a suitable
nozzle or tube opening into the same.
The bag or air chamber placed in the barrel is deflated when the spile of the
barrel is in its proper position in a tube and the cask is full, but when the spile
is withdrawn the air passing through the aperture in said tube into the bag or air
chamber causes it to become inflated and occupy the space left vacant by the liquid
drawn off.
My invention is clearly represented in the annexed drawings.
Figure 1 part sectional elevation of a cask A with my air pressure inflatable
bag B pushed down to about level with the bottom by a tube C by which through
perforations D the air has inlet to the bag for inflating and expanding it the
greater portion of the bag B being at the upper part of the cask A as represented
more particularly at the sectioned elevation (reduced) at Figure 2, the inflation of
the bag being in proportion to the quantity of liquid drawn off by the tap E
To prevent the bag B being torn or injured by the pipe C I secure a knob F of
cork or other material as a guard on its lower end, the upper end G being free to
slide in the stopper H to adjust itself to the different sizes of casks to which my
inflatable bag and appliances are applicable, .e. If the cask be a large one, the
upper end of the tube C may be as represented but if applied to a small cask its
upper end could by sliding in the stopper H stand up and project above, so that
it is not limited for use with one size of cask. The bag B as will be seen has its
mouth drawn into an annular groove or channel in the neck of the stopper H so
that air entering the bag must pass through the tube C.
I have shown in dotted lines a spile or spigot I as fitted in the upper end of the
tube C to be removed each time a quantity of liquid is drawn off but this is not
essential as any dust getting into the open ended tube could not get into contact
with the liquid.
The apparatus is applicable for jars, tanks and other vessels.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
-
Apparatus as shown on the annexed drawings consisting of bag B suspended
from stopper H within a liquid container such as a cask and having part held down
by perforated tube C provided with guard knob at lower end and with upper end
free to slide in stopper H as set forth.
