PROVISIONAL SPECIFICATION.
Improvements in Vent-pegs for Beer and other Casks.
I, JAMES WILDS of 5 D Block, Peabody's Buildings, Farringdon Road, Clerken-
well, London, Commissionaire, do hereby declare the nature of this Invention to be
as follows
This Invention relates to improvements in ventpegs for admitting air to casks
containing beer and other liquids.
The peg is made in the shape of a small cylinder terminating at one end in a
taper screwed plug through which is a passage communicating with the interior of
the cylinder. In the bottom of the cylinder immediately above the plug is a ledge
or shoulder upon which rests a spiral spring and on the upper end of this spring is
placed a valve which by the extension of the spring is pressed against an orifice in
the cap of the cylinder, the said cap being screw threaded so as to engage with a
similar screw thread formed either on the inside or outside of the said cylinder.
When the gaseous pressure within the cask combined with the pressure exerted by
the spring is equal to or greater than the external atmospheric pressure no air can
enter the cask, but when through a vacuum being created in the cask or in the
delivery pipe as will occur when drawing off the beer or other liquid by means of
a pump the spring will be compressed and the valve opened by suction from the
engine until sufficient air has entered the cask and the equilibrium between internal
and external pressure has been restored Amongst other advantages it will be observed
that this construction of ventpeg renders impossible the introduction of air into the
cask by blowing down the delivery pipe.
The ventpeg can also be worked in a barrel that is not connected with an
engine by inserting a small plug in the vent hole and pressing on the valve when air
is required to be admitted.

COMPLETE SPECIFICATION.
Improvements in Vent-pegs for Beer and other Casks.
I, JAMES WILDS of 5, D Block, Peabody's Buildings, Farringdon Road Clerken-
well, London Commissionaire 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 improvements in vent-pegs for admitting air to casks
containing beer and other liquids and will be readily understood on reference to
the accompanying sheet of drawings in which Fig. 1 represents an elevation of a
vent-peg constructed according to my invention and Fig. 2 a vertical section
thereof.
The peg is made in the shape of a small cylinder A terminating at one end in
a taper screwed plug B through which is a passage b communicating with the
interior of the cylinder-In the bottom of the cylinder immediately above the plug
15 a ledge or shoulder a upon which rests a spiral spring C and upon the upper
end of this spring rests a valve D which by the extension of the spring is pressed
against an orifice or valve seat formed in the cap A' of the cylinder the said cap
being screw threaded so as to engage with a similar screw thread formed either
on the inside or outside of the said cylinder.

page_text: When the gaseous pressure within the cask combined with the pressure exerted
by the spring is equal to or greater than the external atmospheric pressure no
air can enter the cask, but when through a vacuum being created in the cask or
in the delivery pipe as will occur when drawing off the beer or other liquid, by
means of a pump the spring C will be compressed and the valve D opened by
suction from the engine, until sufficient air has entered the cask and the equlibrium
between the internal,and the.external pressure has been restored.
This vent peg can also be applied to a barrel that is not connected with an
engine or pump by inserting the plug end thereof in the vent hole as before and
replacing the action of the pump" by pressing with the hand on the 'button (d of
the valve when air is required to be admitted.
Amongst other advantages it will be observed that this construction of vent-peg
renders impossible the introduction of air into the cask by blowing down the
delivery pipe.
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
clau 18-
The construction of a vent-peg consisting essentially of a cylinder A terminating
in a perforated plug B for the purpose of providing an inlet for air to the barrel,
such inlet being closed by means of a spiral spring C and valve D substantially
as herein described and illustrated in the accompanying drawings.
