I, CHARLES WAYTE, of 7, Gladstone Cottages, Epsom, in the County of
Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an inexpensive automatic vent peg for casks and other
vessels.
The improved vent peg can be used in any kind of cask and does not offer
any obstacle to the cask being rolled about, and the peg having been once inserted
will last for months as the cask can be washed out without risk of injury to
the peg.
I construct my peg of a hollow metal cone the diameter and taper being about the
same as that of an ordinary vent peg but the cone is shorter and slit downwards from
the top in three or four places so that the upper part of the cone which projects
beyond the cask after the cone has been driven in can be laid over upon and level with
the cask; the portions of the cone formed by slitting the same can be used to extract
the peg by means of a pair of pliers or the like when required to be replaced by a new
one; over or in the smaller end of the cone I place a piece of elastic tube having five
or six incisions and made airtight at its end.
A piece of wire long enough to enter the small end of the cone is introduced into
the elastic tube thus forming a valve which will allow air to enter the cask when

required, and prevent the escape of the liquid when the cask is rolled.
pressure within the cask causes the incisions to close up round the wire inside
the tube.
It will be obvious that a similar result can be attained by inserting in the cone a
valve which is brought to its seat by means of an elastic substance such as india-rubber
fibre or thread.

page_text: I, CHARLES WAYTE, of Carville, College Road, Epsom, in the County of Surrey,
Engineer, 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 an inexpensive automatic vent peg for casks and other
vessels.
The improved vent peg can be used in any kind of cask and does not offer any
obstacle to the cask being rolled about, and the peg having been once inserted
will last for months as the cask can be washed out without risk of injury to
the pcg.
I construct my peg of a hollow metal cone the diameter and taper being about the
same as that of an ordinary vent peg but the cone is slit downwards from the top in
three or four places so that the upper part of the cone which projects beyond the cask
after the cone has been driven in can be laid over upon the cask; the portions of the
cone formed by slitting the same can be used to extract the peg by means of a pair of
pliers or the like when required to be replaced by a new one; over the smaller end of
the cone I place a piece of elastic tube having a number of slits or incisions and made
airtight at its end.
A piece of wire or an equivalent core long enough to enter the small end of the
cone is introduced into the elastic tube thus forming a valve which will allow air to
enter the cask when required, and prevent the escape of the liquid when the cask is
rolled. The pressure within the cask causes the incisions to close up round the core
inside the tube.
It will be obvious that a similar result can be attained by inserting in the cone a
valve which is brought to its seat by means of an elastic substance such as india rubber
fibre or thread.
In order to enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which
Figures 1 and 2 are elevations, and
Figure 3 is a section of an automatic vent peg constructed according to my invention
and shown inserted in the usual spile hole of a cask, a portion of one of the staves of
which is represented in section.
Figures 1 and 3 represent the valve of the vent peg in its normal or closed position
and figure 2 shows the valve open.
Figure 4 is a plan of figure 1.
Figure 5 is a horizontal section on line A B of figure 2.
Figure 6 is a similar view to figure 3 but illustrating a modified arrangement of my
improved vent peg, and
Figure 7 is an elevation of the vent peg before being fixed in the cask.
Similar letters in all the figures indicate similar parts.

page_text: a is the hollow metal cone, and b, b are the portions of the cone which are laid down
upon the cask Cafter the cone has been driven in, it being slit downwards from the
top in three or more places for that purpose. The portions 6,6 can be used for
extracting the peg in the manner hereinbefore referred to.
c is the piece of elastic tube which I fit over the smaller end of the cone; d, d are
the slits or incisions in the tube c which is closed up air-tight at its lower end by being
bound to a piece of wire or an equivalent core e introduced into the elastic tube which
thus forms a kind of valve.
From the foregoing description it will be easily understood that the cask can be
rolled about with the vent peg inserted therein as the peg will offer no impediment
thereto, and the valve will prevent the liquid from escaping through the vent peg.
Also when the liquid is withdrawn from the cask the air will enter through the slits or
incisions d, d in the clastic tube c which under the pressure of the said air will open
somewhat in the manner shown in figures 2 and 5.
Further the cask can be washed out without risk of injury to the peg which having
once been inserted in the cask will therefore serve repeatedly for a considerable time
and when eventually it is required to remove it this can easily be done by raising the
portions b, of the cone and gripping them with a pair of pliers.
C
The arrangement shown in figures 6 and 7 is similar to that already described by
reference to figures 1 to 5 with the exception that the conical portion of the peg is
dispensed with and the upper end of the clastic tube c of the valve is made of a
bulbous form, as shown at fin figure 7, with a hole g (figure 6) therein. The bulbous
portion of the tube serves to form a tight joint between the cask C and a fixing
plate h by being flattened and compressed between the two when the plate h is screwed
to the cask as will be seen by reference to figure 6. The plate his formed with a hole i
corresponding to the hole g in the top of the elastic tube.
The action is the same as that of the vent peg illustrated in figures 1 to 5.
It will be obvious that instead of forming the elastic tube with a bulbous hea. 23
shown in figure 7 it can be provided with a flange to serve as the seating between the
cask and the plate and also to keep the tube in the centre of the hole in the
cask.
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 comprising an india-rubber or other elastic tube having one or more
slits formed therein and containing a core internally in such a manner that air can
pass from the exterior of the cask between the core and the tube through the slits but
that the pressure within the cask or other vessel will press the said tube into close
contact with the core substantially in the manner described.
2. An automatic vent peg consisting essentially of a hollow metal cone, a slit elastic
tube, and a piece of wire or its equivalent arranged and operating substantially in the
manner and for the purposes setforth.
3. The modified arrangement of automatic vent peg in which the hollow metal cone
is dispensed with and the rubber tube is provided with a bulbous or a flanged head
substantially as set forth.
4. The manufacture and use of the improved automatic vent pegs hereinbefore
described and illustrated in the accompanying drawing
