COMPLETE SPECIFICATION.
A New or Improved Vent Peg or Valve for Casks and the like.
I, OMAR COOк, of No. 1, Field Street, Landore, near Swansea, Glamorgan-
shire, Engine Driver 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 spigot or valve for casks and barrels, and
has for its object to provide a simple arrangement which will automatically supply
air to the cask as the beer or other liquid is withdrawn.
In carrying out my invention I propose to employ a small metal case or cylinder
having a long narrow tube or spigot preferably of slightly tapering form projecting
from the bottom. Within the casing a second tube extends from the bottom
through which it opens almost to the top both ends being open.
The perforation in the bottom of the cylinder is slightly smaller than the tube so
as to form a valve seating, and a small steel or other ball is placed inside the tube
adapted to close the aperture when it drops into the lowest position. The cylinder
is closed at the top by an air-tight cap which can be easily removed when required,
or the casing may be closed in completely.
The narrow projecting tube is forced through the side of the cask extending into
it a suitable distance the cylinder remaining outside.
Air can thus penetrate to the interior of the cask only through the tube in the
cylinder, so that when the ball is in its lowest position the entrance is closed
cutting off any communication between the atmosphere and the interior of the
cask.
On drawing however, the valve will be raised by the displacement and air will
at once pass through the valve into the cask.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings in which Fig. 1 is an elevation of the device
applied to the cask, and Fig. 2 is a section.
A is the cylinder or casing furnished in the arrangement shown with the
removeable cap a. From the lower end of this cylinder the tube or spigot B
projects slightly tapering towards the lower end and adapted to pass through the
side of the cask. The bottom of the cylinder is formed with the small perfora-
tion a' and the tube C extends from this perforation towards the upper end of the
cylinder.
The edge of the perforation forms a seating for the small ball or valve D.
The distance from the top or cap to the upper end of the tube C is not sufficient
to enable the ball to fall out of the tube. Immediately the pressure in the cask
is lowered on drawing the liquid, the ball will be raised from its seat allowing
the air to pass through the tube C into the cylinder and thence through the
tube B.
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) An improved spigot or valve for casks having a small cylinder or casing, a
tube adapted to extend into the cask, and a valve in the said casing admitting air
to the cask substantially as and for the purposes specified.

page_text: (2) In an improved spigot or valve for casks the combination with a cylinder
or casing, and a.tube for insertion in the cask, of a second tube in the cylinder,
carrying a valve, admitting air to the cask, substantially as and for the purposes
specified.
(3) The improved spigot or valve for casks, constructed and operating
substantially as described and shown in the accompanying drawings and for the
purposes specified.
