IMPROVEMENTS IN THE MANUFACTURE OF CORKS, BUNGS AND OTHER STOPPERS
Year: 1885

page_text: I, HENRY GEORGE JACOBSEN of No. 6 John's Lane, Leith, in the County of
Midlothian, North Britain, Cork Merchant do hereby declare the nature of the said
invention for IMPROVEMENTS IN THE MANUFACTURE OF CORKS, BUNGS AND OTHER
STOPPERS to be as follows:-
This Invention, which relates to certain Improvements in the manufacture of
corks, bungs and other stoppers from thin corkwood, is a development or further
extension of the Invention described in the Provisional Specification of the said
Henry George Jacobsen Numbered 11178 A.D. 1884. In the Provisional Speci-
fication accompanying the aforesaid application there is described a means for
uniting together two or more pieces of cork wood so as to form a cork, bung, or
stopper, the means described being a cement varnish consisting of caoutchouc
dissolved in Bi-sulphide of carbon or other solvent of caoutchouc.
In practising the Invention since the date of filing the aforesaid Provisional
Specification it has been discovered that pieces of corkwood may be united or
caused to adhere together by means other than caoutchouc dissolved as aforesaid,
and the present Improvements consist in applying such other means for affecting
such adhesion of two or more pieces of cork. The substances so employed are
gutta percha, balata or others of a like nature in solution; or in place of using
them in solution, these substances as well as caoutchouc may be cut into thin
sheets and the pieces of corkwood united by being pressed closely on to the clean
surfaces of such thin sheets. There may also be used as an alternative, the
natural juices or milk obtained from the trees from which caoutchouc, gutta
percha and balata or other substances of a like nature are obtained, and as another
alternative there may be used as a cementing medium, gum-resins or other
adhesive substance of a kind which is not soluble in the liquid contained in the
bottles or other vessels, which the corks, bungs or stoppers constructed according
to this Invention, are used for closing.

Improvements in the Manufacture of Corks, Bungs, and other
Stoppers.
I, HENRY GEORGE JACOBSEN of N° 6 John's Lane, Leith in the County of
Midlothian, North Britain, Cork Merchant do hereby declare the nature of my said
invention for IMPROVEMENTS IN THE MANUFACTURE OF CORKS, BUNGS AND OTHER
STOPPERS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My Invention, which relates to certain Improvements in the manufacture of
corks, bungs and other stoppers from thin corkwood, is a development or further
extension of the Invention described in the Specification of my Patent No 11,178
A.D. 1884.
In the said Specification there is described a means for uniting together two or
more pieces of corkwood so as to form a cork, bung, or stopper, the means described
being a cement varnish consisting of caoutchouc dissolved in Bi-sulphide of carbon
or other solvent or solvents of caoutchouc.
In practising the Invention since the date of the aforesaid Patent it has been
discovered that pieces of corkwood may be united or caused to adhere together by
means other than caoutchouc dissolved as aforesaid, and the present Improvements
consist in applying such other means for effecting such adhesion of two or more
pieces of cork.-The substances so employed are gutta-percha, balata or other
substances of a like nature in solution. There may also be used as an alternative,
the natural juices or milk obtained from the trees from which caoutchouc, gutta-
percha and balata or other substances of a like nature are obtained, and as another
alternative there may be used as a cementing medium, gum-resins or other
adhesive substances of a kind which are not soluble in water or in the liquid
contained in the bottles or other vessels, which the corks, bungs or stoppers
constructed according to this Invention, are used for closing.
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
First. The uniting of two or more pieces of corkwood to form a cork or bung or
analogous article by gutta-percha or balata, or other substances of a like nature
in solution.
Second. The uniting of two or more pieces of corkwood to form a cork or bung
or analogous article, by the natural juices or milk of the trees from which
caoutchouc, gutta-percha, balata or other substances of a like nature are obtained.
Third. The uniting of two or more pieces of corkwood to form a cork or bung.
or analogous article by gum resins or other substances of a like nature insoluble in
water or in the liquid to be corked or stoppered.
Dated this thirteenth day of January 1886.
