You're welcome @nycet3.
It's a very niche subject I know, but of historical interest I guess.
Hopefully some light may be shed on the subject one day.

Just found this US patent, number 676562A, granted on 18th. June, 1901, to a Mr Jens Henri Langgaard of Liverpool, England.....

Sadly, close but no cigar!
The patent is for a segmented cork insert, but without the metal internal rod.

I've found another US patent, number 578134, granted on

March 2nd. 1897, to a Mr. J.A. Burton of Skaneatles, New York.
Again with segmented cork, but this time with a spring running through the segments.
This makes sense, as at least have a fighting chance of fitting them!
