I GEORGE FREDERICK REDFERN of the General Patent Office, No 4 South
Street, Finsbury, in the county of Middlesex Patent Agent do hereby declare
the nature of this invention (a communication from abroad by Auguste Lanart of
Beaumetz-les-loges, in the republic of France, Gentleman) to be as follows:-
This invention relates to an improved means or apparatus for automatically
allowing the escape of gases, liquids or fluids under pressure in vessels or the like
when the pressure exceeds a certain degree.
For this purpose I employ a tube of suitable material communicating at one end
with the liquid, gas, or fluid which is required to escape only at a given degree of
pressure; the other end of the said tube is either closed or in coinmunication with
a valve or with any other suitable vessel or apparatus or the like. I form around
this tube one or more holes and I surround the tube over the hole or holes with
a tube or jacket of india rubber or other suitable elastic material-When the
pressure within the tube has exceeded the limit determined by the tension of the
india rubber the liquid, gas, or fluid escapes through the space produced by means
of such pressure between the tube and the jacket of india rubber or other suitable
elastic material.

I GEORGE FREDERICK REDFERN, of the General Patent Office N° 4, South
Street, Finsbury, in the county of Middlesex, Patent Agent do hereby declare
the nature of this invention (a communication from abroad by Auguste Lamart
of Beaumetz-les-loges in the republic of France, Gentleman) 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 means or apparatus for automatically
allowing the escape of gases, liquids or fluids under pressure in vessels or the like
when the pressure exceeds a certain degree.
The improved apparatus is represented in the accompanying drawing in which
Figure 1, represents an elevation and figure 2 a vertical section of the same.
Similar letters in all the figures represent similar parts.
A is a chamber containing a valve B, opening inwards; C, D is the main tube
which is screwed at D into the cask or other vessel containing fermentable liquid
which produces a varying pressure. This tube is perforated with a hole (or several
holes) F and on the outer part of the tube is fitted a tube or jacket of india rubber
or other suitable elastic material which is of such a size as to exert a certain
pressure on the sides of the tube C, D. If the liquid contained in the cask gives
off carbonic acid or other gas too freely the pressure will increase and the india
rubber tube or jacket E will be stretched or widened and will allow the super-
abundant quantity of gas to pass through the hole F between the tube C, D and
the tube or jacket E.
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
A tube adapted to be applied to a cask or other vessel containing a fermentable
liquid the said tube being closed at the end opposite to that inserted in the vessel
(or provided with a valve opening inwards) and provided with one or several
holes covered by the inner surface of a jacket of india rubber surrounding the tube
and exerting a certain pressure on the said tube so as to allow the gas within the
vessel to escape only when the pressure thereof exceeds a given degree substantially
as hereinbefore described.
