COMPLETE SPECIFICATION.
Improvements in Vent Pegs.
I, EDWIN BENNETT, of Winterdyne, Selly Park, near the City of Birmingham,
Gentleman 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 means for admitting or excluding atmospheric air from
beer and other like barrels and casks, and which said means, as hereinafter described,
are in commerce known as "vent pegs.'
,,
Figure 1 of the accompanying drawing represents a barrel, provided with a vent
peg, constructed, fitted and provided with improvements made according to my
invention. The said barrel or portion of it is shown in section, whilst the vent peg
is shown in elevation.
Figure 2 represents a vertical section of the said vent peg Figure 1, and with
the valve forced home upon its seat.
Figure 3 represents a like sectional view as Figure 2, but with the valve off its
Beat.
Figure 4 represents a top-side view of the vent peg Figure 1.
Figure 5 represents a transverse section upon the dotted lines A. B Figure 3.
a is the body part of the peg, consisting of a hollow and screwed stem lower
part a', an upper box or chambered part a³, a depending hood part a', with scolloped
edges or outlets a°. Directed from two of the opposite sides of the said chambered
part, are arms, or capstan arms a, whilst screwing upon the open top a', is a
cover a, through the middle of which the stem 6, of a lever or thumb screw b,
takes. This said screw is fitted with a disc or pressure plate 63, and a stalk 6, with
a headed end b, and upon the said stalk, a conical plug or valve c, preferably of
wood, vulcanite or such like material, is loosely fitted, and is capable of sliding upon
the said stalk, which is longer than the plug or valve.
The chambered body part a³, has at its inside lower end, outlet passages a³,
lead to the hood or cowl a*.
which
The object of the said hood or cowl is to prevent the liquid contained within a
barrel, spurting, on the introduction or opening of the vent peg. Thus, should any
liquid be forced past the valve, and into the body of the vent peg, then the samé
escapes through the outlet holes a³, into the overhanging hood or cowl a', and is
then allowed to run or be projected only upon the top of the barrel d, instead of the
same spurting upwards, as is common with ordinary vent pegs.
The gimlet pointed stem a³, has holes or passages a¹, through which the air
supplied by the vent is admitted to the barrel.
Assuming that the valve is upon its seat, as in Figure 2 no air can be admitted
to the barrel, but by turning the cross end of the screw b, the valve is taken from
its seat, usually by the inside pressure in the barrel, but should the said pressure be
insufficient to raise the valve, by rotating backwards the said screw further, the
head 6, of the stalk 6, is brought under the valve, hence the lifting of it.
The valve is taken to its seat by the pressure plate 63, coming upon the top side
of the said valve on the screwing home of the screw.
Assuming that the valve is from its seat, as in Figure 3, and that the pressure
within the barrel is sufficient to slightly lift the same to that position, then by the
valve being thus opened, an equilibrium of pressures is established, and the valve
automatically falls to its seat, and prevents the further ingress of air until liquid is
required to be drawn from the barrel or cask, when the valve is again slightly lifted
to admit only the air necessary for allowing a free flow of liquid.

page_text: Immediately an equilibrium is restored, the valve falls and may be made to have
an automatic action, or to be kept to its seat by the turning of its screw.
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 :-
:-
First In a vent peg, providing the hollow or upper stem part of the same with
a box or chambered part, fitted with outlet holes, leading to a hooded or cowled
outlet, as set forth.
Secondly-In a vent peg, the combination with the body part, of a pierced
hood or cowl a', whereby escaping liquid is directed downwards upon the top side
of the barrel, instead of spurting upwards, as set forth.
Thirdly-In a vent peg, providing the said body part with a loosely fitted and
sliding valve, carried upon a stalk, having upper and lower abutments, and being
carried by a propelling and repelling screw, as set forth.
Fourthly In a vent peg, the combination with an outside screwed and hollow
stem, of a box or chambered valve body part, as set forth.
Fifthly-In a vent peg, the general construction, arrangement and combination
of the parts, as described and set forth.
