Containing Liquids.
I GEORGE HENRY WHITE of Regent Street Dunstable in the county of Bedford
builder do hereby declare the nature of my invention for A NEW OR IMPROVED
VENT PLUG FOR CASKS, BARRELS OR OTHER VESSELS CONTAINING LIQUIDS to be
as follows:-
This invention relates to a new or improved self closing Vent Plug which may be
constructed of Brass or any other metal and screwed into the Cask or Barrel as shewn
in Section on plan, the plug is bored out the required depth to receive a spiral spring
(marked D in Section) and a smaller hole is continued through the bottom and
counter sunk on the underside to receive a India-rubber washer which is fixed on the
Stem which passes through the spiral spring, the stem is formed as shewn on plan E.
The object of this invention is to facilitate the drawing off of any portion of the
said liquids and also avoid any deterioration of the liquids remaining in the Casks or
Barrels etc when the required amount is drawn off.
By the pressure of the finger on the top of the before mention Stem a precise
amount of air can be admitted into the Cask or Barrel and on releasing the same it
becomes self closing and airtight.
The subject of this Invention is simple in construction, easily fixed and not liable to
get out of order by either the washing, filling, rolling or loading the Casks, Barrels etc.

I, GEORGE HENRY WHITE, of Regent Street, Dunstable, in the county of Bedford,
builder, 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 and accompanying drawing (that is to say) :-
My present invention relates to vent plugs as ordinarily used for casks, barrels, or
other vessels containing liquids, and it has for its object a novel method of making
such vent plugs so that they are self-closing, simple in construction, easily fixed and
not liable to be injured or get out of order during the washing, filling, rolling, or
loading the casks, barrels, or other liquids.
The accompanying drawing is in illustration of my invention, figure 1 being a trans-
verse section through part of a cask or barrel having the improved vent plug fitted to it.
a is the plug itself of brass or any other suitable metal or material, and having an
external thread, as shewn in figure 2, by which it is screwed into the cask b. This
plug a is preferably formed with a flange at its upper end fitting into a recess in the
cask as shewn, and the flange may be flattened at its sides (as shewn in figure 3) to
facilitate fixing it in its place.
The plug a is bored out to receive spring d, a smaller hole being continued
through the bottom and recessed or countersunk on its lower side to form the seat for
a washer e (shewn from below in figure 5) of india rubber or other suitable material
which is fitted upon the stem and drawn against the seat by the spring d. The stem f
passes through the spring and is formed as shewn in figures 1 and 4, the upper end
serving as a button by which it can be pressed down and the washer or valve e opened.
By the pressure of the finger upon this button or top of the stem f, the drawing off of
any desired quantity of liquid from the cask is facilitated, and the deterioration of the
liquid remaining in the cask or barrel when the required quantity has been drawn off
is prevented. By the pressure of the finger as described the precise amount of air
necessary can be admitted into the vessel, and on withdrawing the pressure, the valve
or washer is instantly and automatically closed airtight. As the device does not pro-
ject from the cask it is not liable to injury.
The size and proportions of the parts of the improved vent plug may be varied more
or less as desired.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :--
The combination of the plug. a washer e, stem f and spring d, arranged and
operating substantially as and for the purpose described and shewn.
