PROVISIONAL SPECIFICATION.
An Improved Vent Peg.
I, EDWIN BARRON, of 85, Fairfax Road, in the County of Middlesex, Com-
mission Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of an improved vent peg, that is to say,
a rent peg which not only allows the contents of a cask or other vessel to be drawn
off when the draw-off cock or tap is opened but which will also allow of the
escape from the cask of the gases generated from fermentation or the like.
In carrying out my invention employ a hollow vent peg made of suitable
material and adapted to be driven or screwed into a cask in the usual manner.
In the upper part or head of the vent peg I form a chamber adapted to receive
any suitable porous material, such for example as sponge, the said porous material
or packing being held in place and compressed to the required degree by means
of a perforated screw or other cap fitting into the said chamber.

COMPLETE SPECIFICATION.
An Improved Vent Peg.
I, EDWIN BARRON, of 85, Fairfax Road, in the County of Middlesex, Com-
mission Agent, do hereby declare the nature of this invention, and in what manner
the same is to be perfornied, to be particularly described and ascertained in and by
the following statement :-
This invention relates to the construction of an improved vent peg which not
only allows the contents of a cask or other vessel to be drawn off when the draw-off'
cock or tap is opened, but which also allows of the escape from the cask of the
gases generated by fermentation or the like.
In
In carrying out my invention I employ a hollow vent peg proper made of suitable
material and adapted to be driven or screwed into a cask in the usual manner.
the upper part or head of the vent peg 1 form a chamber adapted to receive a
suitable porous material or packing, such for example as sponge, the said porous
material or packing being held in place and compressed to the required degree by
means of a screw or other cap fitting into the said chamber.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is an elevation of a vent peg constructed according to my invention:
Figure 2 is a section on the line, Figure 1:
Figure 3 is a vent peg of slightly modified construction.
a indicates the vent peg proper having through it a passage b; c is the chamber
formed at the upper end of the vent peg, and d the packing material located in the
Baid chamber. e is the cap which, as shewn, is screwed into the upper part of the
chamber c and serves to press the packing therein. f,f indicate openings formed
around the head of the vent peg and communicating with the chamber therein, the
said openings serving to allow the admission of air or the escape of gas.
It is obvious that by screwing down the cap e more or less, the packing material
will be correspondingly compressed, the amount of compression being preferably
such that a certain proportion of the gas generated within the cask may be allowed
to escape.

page_text: The vent peg can be made of wood, vulcanite, metal or other suitable material
and as shewn it is provided with screw-threads g for fitting it into the hole in the
cask. It may, however, be left plain and driven into the cask.
I sometimes provide the vent peg with wings h, as shewn in Figure 3 for
facilitating its application.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. A vent peg provided with a chamber for containing a porous material and
with a screw for more or less compressing such material in the said chamber,
substantially as, and for the purpose described.
2. The manufacture and use of the improved vent peg hereinbefore described
and illustrated in the accompanying drawing.
