ARTHUR EDMUND WEATHERHEAD 'Cranmer Villa, Granville Road Wigston
Fields Wigston Leicestershire, Accountant JOSEPH WYATT HANCOCK Montague
Road Clarendon Park Knighton Leicestershire Gas Fitter do hereby declare the
nature of this invention to be as follows:-
An automatic vent peg which can be turned or moulded in wood or metal to any
shape to suit the manufacturer, a hole is drilled from top to bottom. The body.of
the vent peg has a circular cavity with a flat bottom on which rests a round disk
with two holes drilled through it and having a pivot in the centre vertical which
acts as a guide to a cone which covers it. The lid is provided with a collar which
fits tightly inside the body of the vent peg, at the same time goes far enough down
the inside to keep the disk from getting out of place and also allows a slight
movement to the cone up or down. Its action presuming it is already fixed will be
thus. The force which is generated by the beer etc. contained in the barrel forces
the loose cone up into the conical cavity, completely making it vent proof, upon
opening the tap for drawing beer, the inside pressure being reduced and the external
atmosphere being greater it forces down the cone on to the disk. The said cone
having little nicks made in its base. The air passes through these nicks, thence
passes through the two holes underneath it in the middle of the disk and finally
reaches the inside of the barrel by the taper portion inserted in it.
The wood lid contains a metal lining in the conical cavity in which the inner
cone fits making an air tight joint.

COMPLETE SPECIFICATION.
An Improvement in Vent Pegs for Beer Barrels and the like.
We, ARTHUR EDMUND WEATHERHEAD, Wigston Fields, near Leicester,
Accountant, and JOSEPH WYATT HANCOCK, 49 Montague Road, Clarendon Park,
Leicester, Gas Fitter, 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 construction of vent pegs for beer barrels
and the like.
The invention will be understood from the following description in reference to
the accompanying drawing in which
Figure 1 is a central vertical section of a vent peg constructed in accordance
with this invention.
Figure 2 is a similar view of a modification.
Each of the above figures is drawn to an enlarged scale in order to more readily
assist to a clear understanding of the invention.
The lower part A of the vent peg is tapered and threaded so as to admit of being
screwed into the barrel.
It is provided with a central passage B communicating by two branch
openings B with a cavity C formed in the upper end of the part A.
The wall A of the cavity C is internally threaded to receive and into which is
screwed the lower threaded end of the detachable head or upper part D which is
also provided with a central passage D¹.

page_text: The central part of the cavity C has secured thereto or formed integrally there-
with a fixed cone E or equivalent projection, upon which rests loosely and so as to
be capable of a certain amount of play, a shell cone F or equivalent.
The admission of air takes place down the passage D', under the bottom of the
loose cone F and through the passages B' and B into the barrel but the escape of
air or gas is prevented by the force or upward current of same getting inside the
loose cone F and forcing it into the passage D' thereby forming an air-tight joint.
The length of the screwed lower portion of the head D is regulated so that when
tightened within A¹ sufficient room is allowed for a slight up and down and lateral
movement of the loose cone F.
If preferred the loose cone F may be constructed in relation to the 'fixed cone E
so as to fit the latter and allow the base of the former to rest level upon the floor of
the cavity C.
In such case small openings or apertures may be made in the lower circum-
ferential edge of the base of the loose cone F to allow the air to pass into the
passage B and B.
In the modification shewn in Figure 2 the loose cone F is maintained in its
higher position to form an air-tight joint under the influence of a spiral spring G,
but upon the barrel tap being turned on the atmospheric pressure depresses
the loose cone and allows the admission of air into the barrel as hereinbefore
described.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A vent peg for beer barrels and the like consisting of a lower portion A
provided with air passages B, B1, cavity such as C, fixed cone such as E,-loose
cone such as F, upper part such as D with passage D' substantially as described
and illustrated in the accompanying drawing.
2. A vent peg for beer barrels and the like constructed and operating
substantially in the manner described and illustrated in Figures 1 and 2 of the
accompanying drawing.
