IMPROVEMENTS IN CORK-SCREWS.
Year: 1882

page_text: LETTERS PATENT to Gerard Wenzeslaus von Nawrocki Proprietor of the
Firm of J. Brandt and G. W. v. Nawrocki Patent Solicitor and Civil
Engeer of 124 Leipzigerstrasse Berlin Germany for an Invention of
IMPROVEMENTS IN CORK-SCREWS. A communication from Richard Hessel
at Berlin Germany
PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus von
Nawrocki at the Office of the Commissioners of Patents on the 11th March
1882.

GERARD WENZESLAUS VON NAWROCKI Proprietor of the Firm of J. Brandt
and G. W. v. Nawrocki, Patent Solicitor and Civil Engineer of 124 Leipziger-
strasse Berlin Germany "IMPROVEMENTS IN CORK-SCREWS."
This Invention relates to an improved construction of corkscrews whereby the
cork is automatically removed therefrom so as to avoid soiling the fingers as also
to save the time required for removing the cork by hand. For this purpose there
is provided on the stem of the corkscrew, above the screw a conical or tapering
enlargement with or without angular projections or ribs. A cork having been
drawn from a bottle, it is left on the stem so that on screwing the corkscrew into
the cork of another bottle the conical enlargement is forced down through the cork
previously drawn and is thus made to split it open and cause it to fall off the
stem of itself.

GERARD WENZESLAUS VON NAWROCKI Proprietor of the Firm of J. Brandt
& G. W. v. Nawrocki Patent Solicitor and Civil Engineer of 124 Leipziger-
strasse Berlin Germany "IMPROVEMENTS IN CORKSCREWS." A communication
from Richard Hessel at Berlin Germany
This Invention relates to an improved construction of corkscrews whereby the
cork is automatically removed therefrom so as to avoid soiling the fingers as also
to save the time required for removing the cork by hand. For this purpose there
is provided on the stem of the corkscrew above the screw a conical or tapering
enlargement with or without angular projections or ribs. A cork having been
drawn from a bottle, it is left on the stem so that on screwing the corkscrew into
the cork of another bottle the conical enlargement is forced down through the cork
previously drawn and is thus made to split it open and cause it to fall off the
stem of itself.
Figs 1 and 2 of the accompanying Drawings shew two views of a corkscrew
constructed according to this Invention. Immediately above the screw a, a conical
enlargement d is formed on the stem b, which may either be straight or curved.
The cork A being left on the corkscrew it will, on screwing the latter into the
cork B, be held stationary by the friction between it and the other cork, so that
the screw in descending through it will cause the cone d to be forced into it so as
to split it open. Fig. 3 shews the improved corkscrew combined with a holder f.
It will be seen that when corks require to be drawn in rapid succession from a
number of bottles, this Invention will effect a considerable saving of time as it
dispenses with the screwing off of each cork before drawing the next one.
Having thus described the nature of this Invention and in what manner the
same is to be performed as communicated to me by my correspondent, I claim :-
Constructing corkscrews with a conical or other shaped enlargement d above
the screw for the purpose set forth.
In witness whereof I the said Gerard Wenzeslaus von Nawrocki have
hereunto set my hand and seal this First day of August in the year of
our Lord One thousand eight hundred and eighty two.
