PROVISIONAL SPECIFICATION.
An Improved Means and Method of Closure for the Regulation of
Gaseous Pressures.
EDMUND JAMES MILLS, 60 John Street, Glasgow, Professor of Technical
Chemistry, and CHARLES JAMES ELLIS, 4 Woodlands Road, Glasgow, Technical
Chemist, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the automatic relief of gaseous pressure, as in
the case of bottled beer, effervescing wines, peroxide of hydrogen, hypochlorites,
and their admixtures, aerated waters and the like; especially where owing to
spontaneous decomposition or other causes the internal pressure may alter beyond
a certain desirable amount We carry out our invention by fixing on an aperture
in the vessel which contains the substance under, or to be under, gaseous pressure, a
piece of elastic material punctured with one or more holes or slits. The thickness
and effective diameter of the piece mainly determine the pressure under which the
punctures will give way, and so relieve to any desired extent the gascous pressure.
It is desirable in some cases to lubricate the punctures with a dry lubricant, such
as powdered mica or plumbago, to prevent their adhesion at their own surfaces.
The elastic material may form part of a stopper or other attachment to a bottle,
cask, or vessel.
Our invention may obviously be also applied to the regulation of vacua, as for
instance of air pumps.

EDMUND JAMES MILLS, 60 John Street, Glasgow, Professor of Technical
Chemistry, and CHARLES JAMES ELLIS 4 Woodlands Road, Glasgow, Technical
Chemist 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:-
C
This invention has for its object the automatic relief of gaseous pressure, as in
the cas of bottled beer, effervescing wines, peroxide of hydrogen, hypochlorites,
and admixtures, aerated waters, and the like; especially where, owing to
spontan decomposition or other cause, the internal pressure may alter beyond a
certain: irable amount.
We cry out our invention by fixing, on an aperture A in the vessel or
stopper of the vessel which contains the substance under or to be under gaseous
press piece of elastic material B punctured with one or more holes or slits C.
The thickness and effective width of the piece mainly determine the pressure under
which the punctures will give way; and so relieve to any desired extent the
gaseous pressure.
It is advisable in some cases to lubricate the punctures with a
dry lubricant such as powdered mica or plumbago, to prevent any adhesion at their
own surfaces. The elastic material may form part of a stopper or other attachment
to a bottle cask or vessel. Our invention may obviously be applied also to the
regulation of vacua, as for instance of air-pumps.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
1
(1) Closing bottles casks or vessels with an elastic material punctured with one
or more holes or slits; the said material being of such a width and thickness as to
permit the passage of gas at a specified pressure;
(2) The lubricating of such puncture or slit with a dry powdered lubricant;
(3) The combination of a puncture, dry lubricated, in an elastic material, with
a stopper or other fitting of a bottle cask or vessel: all substantially as herein-
before described.
