PROVISIONAL SPECIFICATION.
New or Improved Means-for the Preservation of Hops.
We, MATTHEW ALGERNON ADAMS, Surgeon and Professional Chemist of
Ashford Road, and CHARLES STEPHEN MEACHAM, Brewer of 62 Earl Street both
of Maidstone in the County of Kent, do hereby declare the nature of this invention
to be as follows:-
The object of our invention is to provide means for the preservation of hops
against deterioration by age or keeping. The chief causes of such deterioration are
oxydation and fermentation, if the origin or elements of these causes were removed
and no longer existed deterioration could not occur, and to effect this removal is
the aim and principle of our invention.
To this end we pack the hops in the usual manner and by ordinary methods in a
suitable vessel which after the lapse of the proper time required for maturing is
closed up gas tight, the contained air is then exhausted and in its place is substituted
a suitable gas or vapour, such for example as carbonic acid. We may employ any
suitable kind of vessel but we prefer to use corrugated metal cylinders open at one
or both ends and provided with an attachment for the exhauster but adapted to be
completely and securely closed up gas tight.
The preservation of the hops is accomplished by the removal of the oxygen of
the air required for oxydation, and of the organisms of fermentation.

COMPLETE SPECIFICATION.
New or Improved Means for the Preservation of Hops.
We MATTHEW ALGERNON ADAMS Surgeon and Professional Chemist of
Trinity House, and CHARLES STEPHEN MEACHAM, Brewer of 62 Earl Street,
both of Maidstone in the County of Kent, do hereby declare the nature of this
invention and the manner in which the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The object of our invention is to provide means for the preservation of hops
against deterioration by age or keeping. The chief causes of such deterioration
are oxydation and fermentation; if the origin or clements of these causes were
removed and no longer existed deterioration could not occur, and to effect this
removal is the aim and principle of our invention.
To this end we pack the hops in the usual manner and by ordinary methods in a
suitable vessel.
Before or after the lapse of the proper time required for maturing, which will
vary with the condition and variety of the hops as is well known to those skilled in
their manipulation, the vessel is closed up gas tight; the contained air is then
exhausted and in its place is substituted a suitable gas or vapour, such for example
as carbonic acid, sulphurous acid simple or compound with another or other gas or
vapour, antiseptic or otherwise, according to circumstances.
We may employ any suitable kind of vessel but we prefer to use for the sake of
strength metal cylinders open at one or both ends to facilitate packing, and
provided with any ordinary attachment for the exhauster, but adapted to be
completely and securely closed up gas tight.
The preservation of the hops is accomplished by the removal of the oxygen of

page_text: the air which is essential to oxydation or chemical change or process of fermentation;
and which as has been stated, is the cause of deterioration of hops.
Having now particularly described and ascertained the nature of this inven-
tion and the manner in which the same is to be performed we declare that what we
claim is :-
The means hereinbefore described for the preservation of hops, consisting in
packing the hops in vessels adapted to be and being made gas tight, and then
exhausting all air from same and substituting therefor gas or vapour of suitable
nature such as is above indicated.
