City Patent Office, 23, Rood Lane, Fenchurch Street, in the City of London,
Patent Agents, for an Invention of "AN IMPROVED COMPOUND APPLICABLE
TO THE CAPSULING OF BOTTLES, THE FORMATION OF AIR-TIGHT ENVELOPES
FOR THE PRESERVATION OF MEAT, AND OTHER SIMILAR PURPOSES." A com-
munication from abroad by Auguste Pierre Potel, of the City of Paris, in the
Republic of France, Engineer.
PROVISIONAL SPECIFICATION left by the said Samuel Pearco Wilding at
the Office of the Commissioners of Patents on the 9th April 1880.

AN IMPROVED COMPOUND APPLICABLE TO THE CAPSULING OF BOTTLES, THE
FORMATION OF AIR-TIGHT ENVELOPES FOR THE PRESERVATION OF MEAT, AND
OTHER SIMILAR PURPOSES." A communication from abroad by Auguste Pierre
Potel, of the City of Paris, in the Republic of France, Engineer,
This Invention consists of a novel and improved compound applicable to the
capsuling or covering of bottles, jars, &c., to the formation of an air-tight envelope
for the preservation of meat, &c., and generally to similar purposes where an air-
tight covering is convenient.
The compound is composed of gelatine or other analogous glue or gum, glycerine or
linseed oil, or other analogous fatty body, and solution of tannin in varying
proportions according to the use to which it is intended to be applied.
For the capsuling of ordinary bottles, &c., about three parts of gelatine to one of
glycerine is a suitable proportion, and in order to prevent decay there is added a
solution of about forty grammes of tannin to cach hundred kilogrammes of the other
components. Where the capsule is required to be dry and hard, as is the case where
used on champagne bottles, about one half part of glycerine need only be employed,
one half part of water being added. For the purpose of enveloping meat, fish, fruit,
or other matter from which it is desired to exclude the action of the atmosphere,
two and one half of gelatine, and one and one half of glycerine is convenient, no
water being added, and the solution of tannin being applied to the envelope before
its solidification.

page_text: The compound is prepared in a vessel, to which is applied a gentle heat, con-
veniently a jacket pan or an inner vessel suspended in an outer one containing
water, the latter of which is exposed to the direct heat of the fire.
The glycerine or oil is placed in the bottom and over it the gelatine or gluo.
During the liquefaction, and until it is complete, they are from time to time stirred.
The liquefaction being complete, where it is intended to apply the compound as a
capsule for bottles, jars, &c., the solution of tannin is now added to and intimately
mixed with it, and it may then be either cast into bars or in pots for future
re-liquefaction and use, or the necks or mouths of bottles may be plunged into it at
ouce; and where it is to be used as a preservative envelope for meat, &c., the
material to be enveloped is plunged into it before the addition of the tannin solution,
and this done, is afterwards plunged into the solution of tannin before the solidifica-
tion-of-the-envelope. __
Any suitable colouring matter may be mixed with the composition while in the
stato of liquefaction, or where a metallic appearance is desired, as when used for
bottles, &c., the bottles inay be plunged into metallic powder before the setting of
the capsule, or the powder may be applied to its surface in any convenient manner,
and the whole subsequently varnished.
In some cases I may employ my composition as a capsule without any cork or
stopper, a sheet of paper or similar material being placed over the aperture to be
closed before dipping into the composition.

SAMUEL PIERCE WILDING, of the Firm of Fell & Wilding, of the City Patent
Office, of 23, Rood Lane, Fenchurch St., in the City of London, Patent Agents.
AN IMPROVED COMPOUND APPLICABLE TO THE CAPSULING OF BOTTLES, THE
FORMATION OF AIR-TIGHT ENVELOPES FOR THE PRESERVATION OF MEAT, AND
OTHER SIMILAR PURPOSES." A communication from abroad by Auguste Pierre
Potel, of Paris, in the Republic of France, Engineer.
This Invention consists of a novel and improved compound applicable to the
capsuling or covering of bottles, jars, &c., to the forination of an air-tight envelope
for the preservation of meat, &c., and generally to similar purposes where an air-
tight covering is convenient.
The compound is composed of gelatine or other analogous glue or gum, glycerine,
or linseed oil, or other analogous fatty body and solution of tannin in varying
proportions according to the use to wich it is intended to be applied.
For the capsuling of ordinary bottles, &c., about three parts of gelatine to one of
glycerine is a suitable proportion, and in order to prevent decay there is added a
solution of about forty grammes of tannin to each hundred kilogrammes of the
other components. Where the capsule is required to be dry and hard, as is the
case where used on champagne bottles, about one half part of glycerine need only to be
employed, one half part of water being added. For the purpose of enveloping meat,
fish, fruit, or other matter from which it is desired to exclude the action of the
atmosphere two and one half of gelatine and one and one half of glycerine is
convenient, no water being added, and the solution of tannin being applied to the
envelope before its solidification.
The compound is prepared in a vessel, to which is applied a gentle heat, con-
veniently a jacket pan, or an inner vessel suspended in an outer one containing
water, the latter of which is exposed to the direct heat of the fire.
The glycerine or oil is placed in the bottom, and over it the gelatine or glue.
During the liquefaction, and until it is complete, they are from time to time
stirred.
-
The liquefaction being complete, where it is intended to apply the compound as
a capsule for bottles, jars, &c., the solution of tannin is now added to and intimately
mixed with it, and it may then be either cast into bars or in pots for future
reliquefaction and use, or the necks or mouths of bottles may be plunged into it at
once; and where it is to be used as a preservative envelope for meat, &c., the
inaterial to be enveloped is plunged into it before the addition of the tannin
solution, and this done is afterwards plunged into the solution of tannin before the
solidification of the envelope.
Any suitable colouring matter may be mixed with the composition while in the
state of liquefaction, or where a metallic appearance is desired, as when used for
bottles, &c., the bottles may be plunged into metallic powder before the setting of
the capsule, or the powder may be applied to its surfaco in any convenient manner,
and the whole subsequently varnished.
In some cases I may employ my composition as a capsule without any cork or
stopper, a sheet of paper or similar material being placed over the aperture to be
closed before dipping into the composition.
And having now fully described and ascertained the nature of the Invention
communicated to me by my foreign correspondent, and the manner in which the
same is to be performed, bo it known that what I claim as novel, and desire to
protect by the aforesaid Letters Patent is,-
An improved compound composed of gelatine or other analogous glue or gum

page_text: with glycerine or linseed oil or other analogous fatty body, and with solution of
tannin, in varying proportions according to the use to which it is intended to be
applied, as and for the purposes hereinbefore substantially described and indicated.
In witness whereof, I, the said Samuel Pearce Wilding, have hereunto set my
hand and seal, this Eigth day of October, in the year of our Lord One &
thousand eight hundred and eighty.
