Improvements in Cork Extractors.
I, ISAAC NEWTON MILLS of Clayton, Kent County in the State of Delaware, United
tates of America, Engineer, do hereby declare the nature of this invention and in
hat manner the same is to be performed, to be particularly described and ascertained
and by the following statement:-
My invention is a cork extractor constructed as fully described hereinafter so as to
cure a strong and positive hold upon the cork without perforating or wounding the
tter, and the necessity of using hinged tools for seizing the cork, and is especially
lapted for application to pen knives in which the blades are pivoted to, and fold into
e handle.

Improvements in Cork Extractors.
I, ISAAC NEWTON MILLS of Clayton, Kent County in the State of Delaware, United
States of America, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention is a cork extractor constructed as fully described hereinafter so as to
secure a strong and positive hold upon the cork without perforating or wounding the
latter, and the necessity of using hinged tools for seizing the cork, and is especially
a lapted for application to pen knives in which the blades are pivoted to, and fold into
the handle.
In the accompanying drawing-
Fig. 1, is a perspective view of my improved extractor.
Fig. 2, is a view showing the same applied to the handle of a clasp or pen knife.
Fig. 3, is an edge view of the blade detached from the knife.
Fig. 4, is a face view of the blade..
Fig. 5, is a perspective view of the blade, showing a modification.
Figs. 6, and 7, are views illustrating the operation of the implement.
The implement consists essentially of a blade 'A,' and a handle 'B.'
The blade 'A' is flat and long in proportion to its width and the handle 'B,' is
connected with one end either fixedly, as shown in Fig. 1, in which the bandle is in
the form of a ring, or pivoted as shown in Fig. 2, in which the handle is that of a
clasp knife.
The blade is provided with a series of transverse shoulders 1, the face of the blade
being beveled toward the point from each shoulder as shown so as to provide a series
of inclined or beveled faces e, along the whole or greater part of the blade, terminating
in a face extending to the end.
The implement thus constructed is used to extract a cork X from a bottle Y,
Figs. 6 and 7, by first inserting the blade as far as possible between the cork and
bottle as shown in Figs. 6, the ribbed side of the blade being toward the cork. The
blade is then canted or carried inward at one edge to press such edge into the cork as
shown in Fig. 7. This has two effects first it opens a passage 'w' for the inlet of air
or escape of gas, and second it compresses the cork so as to secure a bettor hold.
The blade is then withdrawn when the cork will move with it, being thus extracted
without perforation or other injury. It will be evident that by making the implement
in the form of a flat ribbed blade, as set forth, it may be as readily applied to the
handle of a clasp knife as the cutting blades and without any special construction or
alteration of the handle, while ordinary cork screws can only be applied to such
handles by cutting them away and pivoting, the implement to the centres of the handles,
requiring the latter to be made specially to support the blades.
In the construction shown in Fig. 5, there is a longitudinal groove 'v,' which
permits the passage of air or gas, when the blade is introduced between the cork and
bottle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
-
1. A cork extractor having a flat blade provided with transverse shoulders 1, and
beveled faces' substantially as described.
2. A cork extractor consisting of a flat blade provided with a series of trans-
verse shoulders and beveled faces, and a handle B, substantially as described.

page_text: 3. The blade having transverse shoulders and beveled faces, and a longitudinal
groove'' substantially as described.
4. The combination of the blade A, having transverse shoulders and beveled faces
and a case knife handle, the blade pivoted thereto in like manner as the cutting blade,
substantially as described.
