PROVISIONAL SPECIFICATION.
An Improved Vent, Peg or Appliance to Admit Air into Barrels or
other Closed Vessels.
I, EDWARD JOHN BRIGGS, of The Bricklayers Arms, Burnham, in the County
of Buckingham, Builder, Decorator, and Beerseller, do hereby declare the nature
of the said invention to be as follows:-
This invention has for its object "an improved vent peg or appliance to admit
air into barrels or other closed vessels" containing beer, wine, oils, and other
gaseous liquids which have to be drawn off from such vessels or barrels by
means of a cock or tap.
The appliance is simple in construction, efficient and automatic in its action.
The invention consists in the construction of a vent peg n shape in form,
of a piece of tubing or barrel of suitable material and diameter one end of this
tubing or barrel is threaded either parallel or tapered so as to screw into an
opening in the barrel or other vessel.
The other end of the tubing or barrel has a valve formed therein consisting of
a chamber having a plug or cap which screws therein, the inner end of this plug
or cap forms the valve seat, and such plug or cap has a central opening passing
therethrough which is kept closed by the pressure of the gases, generated therein,
on a metallic or other ball which keeps it on the valve seat above mentioned.
It will thus be seen that the gases generated inside the barrel will keep the ball
to its seat and that so soon as the tap or cock is opened the ball will be displaced
by the suction caused and the inlet of air ensured, thereby allowing the contents
of the barrel or other vessel to be easily drawn off.

An Improved Vent, Peg or Appliance to Admit Air into Barrels or
other Closed Vessels.
I, EDWARD JOHN BRIGGS, of The "Bricklayers Arms," Burnham, in the County
of Buckingham, Builder and Decorator, and Beer-seller, 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 improved vent peg or appliance to admit air into
barrels or other closed vessels containing beer, wine or other gaseous or aerated

page_text: liquid or liquids under pressure or otherwise which have to be drawn off from such
vessels or barrels by means of a cock or tap.
The appliance is simple in construction, efficient and automatic in its action.
The invention is illustrated in the accompanying drawings wherein Figs. 1
and 2 are vertical sections of two slightly different forms, Fig. 3 is a section of
part of a barrel with my invention fitted thereto and Fig. 4 is a detail view of a
modification. The same parts are lettered to correspond in all four figures of
the drawings.
The vent peg or appliance is constructed of a piece of tubing A preferably in
the shape of an inverted U as shown, and with one end externally screw threaded
as shown at a, and either parallel as in Fig. 1 or tapered as in Figs. 2 and 3.
This end a is screwed into a correspondingly threaded aperture in the upper part
of the cask, barrel or other vessel B..
The other end of the piece of tubing A has a valve formed therein consisting
of a valve casing C internally or externally screw threaded at the lower end into
or on to which screws a plug or cap D having a central aperture d and at its
inner end a valve seating d' on which rests a loose ball E.
It will be seen that the ball valve E will gravitate to its seat and that it will be held
tightly thereon by the gaseous pressure inside the cask, barrel or other vessel,
and that so soon as the tap or cock is opened to draw off the contents from the
barrel or vessel, the ball E will be displaced by the suction caused thereby and
air will be admitted through the valve to the interior of the cask, barrel or other
vessel thereby allowing the contents to be easily drawn off. This is the position
shown in Fig. 3, the arrow indicating that the air enters the valve through
the aperture therein and passes thence over the valve seat d¹ and around the
ball E and through the tube A to the interior of the cask, barrel or vessel B.
As a modification the casing C and plug D may be made as one piece the casing C
screwing into the interior or on to the exterior of the end of the tube A, or the
casing C may be made in one piece with the tube A and the plug D screwed
thereinto or thereonto as before described.. Or as a further modification the
casing C may be dispensed with, in which ease the end of the tube A would be
internally or externally threaded and the plug D screwed thereiuto, or thereonto,
as shown in Fig. 4, the ball E being of course made small enough to allow the
passage of air around it when displaced from its seating.
Having now particularly described and ascertained the nature of my said a
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
A vent peg or appliance to admit air into casks, barrels or other vessels con-
sisting of a length of tubing externally screw threaded at one end and having
at the other end a valve with a throughway aperture therein, a seating around 4
the upper end of said aperture and a ball or other loose valve resting on said
seating substantially as described and for the purpose stated.
