Improvements in Vent Pegs for Beer Casks and other Vessels
Containing Liquid.
We, WILLIAM SMETHURST, of 17, Castle Street, Barber, and EDWARD KNOWLES,
of 45, Hardcastle Road, Agent, both of Stockport, in the County of Chester, do
hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide an improved form of vent peg for
beer casks and other vessels containing liquid, which is of an exceedingly simple
and cheap construction and keeps beer, stout or the like always in proper
condition.
To this end we use an ordinary conical peg, say of wood, which we form
centrally with a hole extending from the bottom to near the head thereof. In
connection with this hole, we form in the side or through the upper end, a
much larger hole adapted to receive a plug preferably of cork, having a hole
through its centre corresponding in size some what with that in the said peg.
Over the inner end of the hole in the said plug we stretch or secure a thin elastic
or rubber band or the like adapted to act as a valve, so that when drawing liquid
from the cask or vessel, the said valve opens and allows atmospheric air to enter
the cask or vessel whilst otherwise the internal pressure causes the said valve to
close and thus cut off communication with the atmosphere.

Improvements in Vent Pegs for Beer Casks and other Vessels
Containing Liquid.
We, WILLIAM SMETHURST, of 17, Castle Street, Barber, and EDWARD KNOWLES,
of 45, Hardcastle Road, Agent, both of Stockport in the County of Chester, 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:―
This invention has for its object to provide an improved form of automatic
vent or vent peg for beer and stout casks and other vessels containing liquid,
which automatic vent or vent peg is of an exceedingly simple and cheap con-
struction and keeps beer, stout or the like always in proper condition.
And in order that our invention may be more fully understood we have caused

page_text: to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is an elevation, Fig. 2 a longitudinal section and Fig. 3 a sectional
plan of one form in which our invention may be carried out, Figs. 4 & 5 a
longitudinal and a cross section respectively of two other forms, Fig. 6 a plan of
Fig. 5, and Figs. 7 & 8 an elevation and a plan respectively of the automatic
valve detached.
In carrying out our invention and referring to Figs. 1, 2 & 3, according to one
form of our invention, we use an ordinary conical peg a, say of wood, which we
form centrally with a hole b extending from the bottom to near the head thereof.
In connection with this hole, we form in the side of the peg a much larger hole c
adapted to receive a plug d preferably of cork, shown detached in Figs. 7 & 8
and having
a hole e through its centre corresponding in size somewhat with the
hole in the peg a. Over the inner end of the hole e we stretch or secure to the
plug a thin elastic, rubber or the like band f, adapted to act as a valve, so
that when drawing liquid from the cask or vessel, the said valve opens inwardly,
see dotted lines Fig. 2, and allows atmospheric air to enter the cask or vessel
whilst otherwise the internal pressure.causes the said valve to close, see full lines,
and thus cut off communication with the atmosphere and act entirely auto-
matically.
In lieu of employing the valve-plugad in the side of the peg a it may be
employed in the head of the plug a, as shown in Fig. 4, the former method being
however preferable.
Again instead of employing our automatic valve in the said peg, it may be
employed in the bung itself, as shown in Figs. 5 & 6, or at any suitable part
of the cask or vessel as will be readily understood.
I
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1st. In vent pegs for beer or stout casks and other vessels containing liquid, an
automatic valve consisting of a plug having an air hole e and over the inner
orifice thereof secured a thin elastic rubber or the like band f, all substantially
as and for the purpose set forth.
2nd. The automatic valve specified in the preceding claim, inserted into the
vent peg, the bung or any other suitable part of a cask or vessel requiring venting,
all substantially as and for the purpose set forth.
