COMPLETE SPECIFICATION.
An Improved Vent-peg or Device for Admitting Air to Casks or
other Liquid Receptacles while the Liquid is being Drawn Off.
We, AUGUST WEBER, and ANTON SCHÜTZ, Manufacturers, of Solingen, Germany,
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:
Our invention has for its object to provide a simple and reliable vent peg, which
will not allow air to enter the cask as long as the tap remains closed, and which will
prevent the contact of the atmospheric impurities with the liquid in the cask while
the liquid is being drawn off.
In the accompanying drawings, Fig. 1 is a side view and Fig. 2 a section of a
vent-peg embodying our invention, and serving to illustrate the same. Figs. 3, 4
and 5 represent modifications.
The device chiefly comprises a main receptacle a, into which water or other suitable
liquid is introduced through an aperture d, provided with a plug, as shown by Figs. 1,
2 and 5.
To this receptacle is fixed at the bottom, a tube b, b', which extends with its upper
part above the level of the liquid (Figs. 1, 2, 3 and 4) and at the top a tube c, the
upper end of which communicates with the atmosphere, while the lower end dips
into the liquid.
The apparatus is applied to the cask by introducing the lower part b¹ of the central
tube into the bung-hole or between the staves of the cask for which purpose the tube b¹
may be provided with a screw thread.
As long as the drawing off tap remains closed, the cask is hermetically closed
towards the atmosphere, because the liquid contained in the receptacle a will prevent
any access of air.
If now the tap is opened, the air flowing into the cask must pass through the liquid
in the vessel a, on its way from the tube c to the tube b.
The receptacle a may be modified in the manner illustrated by Fig. 5. In this
case the air enters the receptacle from the bottom through one or more small
perforations e, which will not allow liquid to escape, as long as the receptacle is
hermetically closed.
To prevent the liquid in the cask from rising into the receptacle a, if the cask contains
an effervescent liquid, a ball-valve, k is placed in the tube b, b, as is illustrated by
Fig. 4. If the liquid rises, it lifts the light ball-valve, so as to rest against its upper
seat, and close the tube b.
The lower valve seat is provided with slots, so as to allow the air to pass down at
the side of the ball.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A vent-peg, or device for admitting air to a cask, while the liquid is drawn off,
the said vent-peg comprising in its construction a vessel containing liquid; a tube
fixed to the receptacle and adapted to be introduced with its lower end into the cask,
while the upper end extends above the liquid in the vessel; and means for admitting
air to the interior of the same, consisting either of one or more tubes which
communicate at one end with the atmosphere, while the other end dips into the
liquid; or of small openings formed in the bottom of the vessel; substantially as
described.

page_text: 2. A vent-peg constructed substantially as specified in claim 1, and provided
with a check-valve k in the tube b, b' to prevent effervescent liquids from rising into
the vessel a.
