of sharp tempered steel blades fixed on a handle.
is now over with the “pig tail” or the “Archimedean
worm” and the damages caused to the cork.
first prong puller was patented in 1879, and its functioning principle
is quite simple: The two blades (beginning with the longest one) have
to be inserted between the cork and the bottleneck. A rotating movement
has then to be applied to unstuck the cork from the bottleneck and then
remove it. The whole operation is done smoothly in order not to spill
the liquid. Another advantage of the prong puller is that the cork can
be placed back into the bottleneck without any effort.
The model created
in 1899 by Mashil Converse is the simplified model (see picture) of
the Mumford model named “Magic Cork Extractor” which was
patented in 1892. Another very rare and ingenious specimen was studied
and manufactured by Benjamin Lew (Germany, March 1878). This corkscrew
has the particularity to have adjustable steel blades in width so that
the corkscrew could be adapted to any kind of bottlenecks. In addition
of that, the blades could be folded into the handle that was acting
as a protecting sleeve. Thirty years later, L. Maussion patented a very
simple corkscrew based on the Lew’s model: A small wooden piece
acting as a handle is inserted into the rings fixed on top of the two
blades (9th December 1903).
