According to this Invention the cork is drawn without making a hole therein or
through it, and it may thus be used again. The stem of the instrument is made
with a crutch or handle of ordinary form; the stem terminates below in a thin
blade with sharp bottom edge; on the stem is made to slide a sleeve fitted or formed
with another similar blade. The sleeve may be held in place by a spring, and is
preferably forined with a projecting rim, or a couple of projecting horns for facili-
tating the pushing down of the sleeve. The two blades may be pressed together by
means of a staple and lever.
The instrument is used in the following manner-Insert the blade point of the
stem at one side between the cork and the interior of the bottle neck until a stop
on the blade abuts against the bottle neck; theu push down the movable blade,
inserting it in a similar manner opposite to the stein blade. Then by means of the
aforesaid lever press the two blades together (thus nipping the cork between them),
and withdraw the cork, at the same time turning it in the neck.

"IMPROVEMENTS IN CORKSCREWS." (A communication from Benjamin Loen, of
Tilsit, in the German Empire.)
According to this Invention the cork is drawn without making a hole therein or
therethrough, and it may thus be used again. The stem of the instrument is made
with a crutch or handle of ordinary form; the stem terminates below in a thin blade
with sharp bottom edge; on the stem is made to slide a sleeve fitted or formed with
another similar blade. The slceve may be held in place by a spring, and is preferably
formed with a projecting rim or a couple of projecting horns for facilitating the
pushing down of the sleeve. The two blades may be pressed together by means of
a staple and lever.
The accompanying Drawings represent a "corkscrew" constructed according to this
Invention, Figure 1 being a side elevation;. Figure 2, vertical_section; Figure 3,
end elevation; Figure 4, cross section on line A, B, Figure 2; Figure 5, plan; and
Figure 6, cross section on line C, D, Figure 1.
A is the stem, and B the crutch or handle thereon; the stem A is continued
down into a thin blade c, with sharp bottom edge; e is a sleeve which can slide on
the slide A, and is provided with a piece f continued down into a thin blade formed
with a sharp bottom edge; d is a spring for holding the sleeve e in place. The latter
is formed with two horns for taking hold thereof with the fingers; his a lever or
cam held by the staple g; m is a stop on the stem a for the sleeve 6.
The instrument is used in the following manner :-Insert the blade point c of the
stem at one side between the cork and the interior of the bottle neck until a stop
on the blade abuts against the bottle neck, as shewn at Figure 1; then push down
the movable blade f, inserting it in a similar manner opposite to the stem blade c,
as shewn in Figure 2. Then by means of the aforesaid lever h press the two blades
e and f together (thus nipping the cork between them), and withdraw the cork, at
the same time turning it in the neck.
.
And having thus described and ascertained the nature of this Invention I declare
that I claim, a "corkscrew" consisting mainly of a stem with blade part or parts c for
insertion between cork and inside of neck, in .combination with a sliding blade
or blades for insertion between cork and inside of neck, and with lever, cam, or
equivalent means for pressing together said blades, all substantially as set forth.
In witness whereof, I, the said Gorard Wenzeslaus von Nawrocki, have here-
unto set my hand and seal, this Eighth day of December, in the year of
our Lord One thousand eight hundred and seventy-seven. -
