An Improved Automatic Vent Peg or Spile.
JOHN WILLIAM MEADOWS PEYTON of 34 Rose Bank Road, Leeds in the County
of York, Publican, do hereby declare the nature of this invention to be as
follows
This invention relates to certain improvements in vent pegs for beer and other
casks, and has for its object the arrangement of the apparatus so that air is admitted
into the interior of the cask, only when the liquid is drawn off, or when the pressure
inside the cask is less than the atmospheric pressure.
I accomplish my object by screwing into the cask by means of lateral arms, a metal
tube slightly taper, having therein a valve opening inwards, a portion of the side of
the tube being cut out for the purpose of fitting in the valve.
Into the top part of the tube I screw a hollow metal plug, the underside of which is
covered with some soft material such as india-rubber, and against this the valve
presses, owing to it being slightly overweighted on the outside, the fulcrum of the
valve being at the bottom of the slot in the side of the tube.
Thus, while air can readily pass into the cask as the liquid is drawn off, any internal
pressure arising from fermentation tends to keep the valve closed, and the various
parts can be taken from together. in order that they may be cleaned, without
unscrewing the vent peg from the cask.

page_text: I, JOHN WILLIAM MEADOWS PEYTON, of 34 Rose Bank Road, Leeds, in the County
of York, Publican, 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 relates to certain improvements in vent pegs for beer and other
casks, and has for its object the arrangement of the apparatus, so that air is admitted
into the interior of the cask only when the liquid is drawn off, or when the pressure
inside the cask is less than the atmospheric pressure.
I accomplish my object by screwing into the cask by means of lateral arms, a metal
tube having a valve therein which will only open inwards, thus allowing air to pass
into the cask only as the liquid is drawn off, while any internal pressure arising from
fermentation tends to keep the valve closed. I also arrange the various parts so that
they can easily be cleaned without removing the apparatus from the cask.
In order to give a more detailed description of my improved apparatus I append a
sheet of drawings in which Fig. 1 represents an elevation of my improved vent peg,
Fig. 2 a longitudinal section of the same, Fig. 3 a sectional plan showing the regu-
lating valve, and Fig. 4 a section on line a showing the means for preventing
particles of dirt passing into the cask.
I construct my improved vent peg in two main parts A and B both of which have
a holo H through the centre, and the lower portion A. I screw into the cask by means
of the lateral arms C, the portion that enters the cask being made conical or tapering
so as to ensure a tight joint. The two parts A and B screw together at D, and into
the upper portion B I screw the hollow metal plug E at the underside of which is a
piece of india-rubber For other soft material, and in contact with this is the valve G.
This latter extends to the exterior of the vent peg, and is fitted into its place by a
portion of the casing being cut away at G', while it is also weighted slightly at the
outside end, thus keeping the interior portion against the piece of india rubber F, and
the pressure inside the cask tends to keep the valve more firmly pressed against the
india rubber thereby preventing gas escaping out of the cask. When however the
pressure within the cask is less than the pressure of the atmosphere, the valve G is
then depressed, owing to the pressure being greatest on the top, and air is admitted
into the barrel.
In order that no particles of dirt may get into the barrel I cover the hole H with a
piece of india rubber K or other material which diverts the air through the channels
or holes L.
It will be easily seen how the various parts can be readily taken out and cleaned,
without removing the vent peg from the cask.
Having 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 :-
An automatic vent peg or spile the various parts of which can be readily cleaned
without removing the vent peg from the cask, all arranged substantially in the manner
as shown and described.
