San Joaquin County, California, United States of America, Fariner, MONROE
DAVIS EATON, of Stockton, San Joaquin County, California, United States of
America, Insurance Agent, and JAMES SKIFF DUNHAM, of Stockton, San Joaquin

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign Patent
Solicitors, 6 Lord Street Liverpool, and 6 Bank Street, Manchester both in the
County of Lancaster, and 323 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:--
The invention relates to certain improvements in cork screws, which may be
attached to a table, and operated by turning a handle.
It consists of a tube, with a safety cap at the lower end, containing a spiral
spring encircling the stem of the screw rod, a window showing the position of the
cork, a gauge showing the pressure required to pull the cork, a wire puller, also of
such other devices as will be hereinafter described.

A, represents the top of a counter or table, to which the arm I of the tube B is
attached by screws or otherwise. The tube B contains a rod C, having a handle C¹
and a screw end C2. The head of the rod Crests upon a collar E within the tube,
which collar E is secured in position by pins E', inserted through slots in the tube B
and screwed into the collar E. A spiral spring F encircles the stem of the rod C,
its upper end impinging upon the collar E and its lower end upon a seat in the
tube B. There is a window H in the tube B, opposite the screw C2, which enables
the operator to see the position of the cork. Gauge figures E2, at the top of the
tube B, near one of its slots, show the amount of pressure required to extract a
cork. Tapering lugs B¹, near the lower end of the tube B, prevent the cork from
turning. A wire puller D is attached to the surface of the tube B, by a pin at a
seat B. This feature is shown at rest in Figure 1. A safety cap G is screwed to
the lower end of the tube B.
To operate the machine, the wire puller D is reversed so as to allow its hook
end to extract the wire from the neck of the bottle. The cork is inserted within
the cap G. The rod C, with its screw end (2, is turned by the handle C¹, the
pressure or force of the spring F drawing the cork from the bottle. Then by turning
the rod C the reverse way, the cork is ejected from the tube B.
The rod C and its handle C¹ and screw end C2 may be easily removed from the
tube D, for the purpose of repairs, cleaning, etcetera.

Improvements in Cork-screws.
A communication from abroad by ELLSWORTH DOUGLASS MIDDLEKAUFF, Farmer,
MONROE DAVIS EATON, Insurance Agent, and JAMES SKIFF DUNHAM, Farmer,
all of Stockton, San Joaquin County, California, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.(.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex,
Civil 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 :-
The invention relates to certain improvements in cork screws, which may be
attached to a table, and operated by turning a handle.
It consists of a tube, with a safety cap at the lower end, containing a spiral spring
encircling the stem of the screw rod; a window showing the position of the cork; a
gauge showing the pressure required to pull the cork; a wire puller; also of such
other devices as will be hereinafter described, and pointed out in the claims.
Referring to the drawing accompanying the Provisional Specification :-
Figure 1 is a side elevation in position for use, as attached to the counter or
table.
Figure 2 is a section of the same through line XX, Figure 1.
Figure 3 is a detached view of the collar E and its pins E¹.
Figure 4 is a section of the tube B through the line X X, Figure 2.
A, represents the top of a counter or table, to which the arm I of the tube B is
attached by screws or otherwise. The tube B contains a rod C, having a handle ("¹
and a screw end C. The head of the rod C rests upon a collar E within the tube,
which collar E is secured in position by pins E¹, inserted through slots in the tube B
and screwed into the collar E. A spiral spring F encircles the stem of the rod C,
its upper end impinging upon the collar E and its lower end upon a seat in the
tube B. There is a window H in the tube B, opposite the screw C², which enables
the operator to see the position of the cork. Gauge figures E2, at the top of the
tube B, near one of its slots, show the amount of pressure required to extract a cork.
Tapering lugs B', near the lower end of the tube B, prevent the cork from turning.
A wire puller D is attached to the surface of the tube B, by a pin at a seat B². This
feature is shown at rest in Figure 1. A safety cap G is screwed to the lower end of
the tube B.
To operate the machine, the wire puller D is reversed so as to allow its hook end
to extract the wire from the neck of the bottle. The cork is inserted within the
cap G. The rod C, with its screw end C2, is turned by the händle C', the pressure or
force of the spring F drawing the cork from the bottle. Then by turning the rod C
the reverse way, the cork is ejected from the tube B.
The rod C and its handle C¹ and screw end (2 may be easily removed from the
tube D, for the purpose of repairs, cleaning, etcetera.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. The combination substantially as described of the arm I, the tube B containing
the rod C, provided with the handle C and with the screw end C³, the collar E attached
to the tube B by the screw pins E', the spiral spring F encircling the stem of the
rod C and the safety cap G attached to the lower end of the tube B.
2. The combination substantially as described of the tube B, the tapering lugs B¹
and the cap G, the tube B containing a suitable rod with screw end and spiral
spring.

page_text: 3. The combination, with the tube B containing a suitable cork extracting
mechanism, of the window H and the gauge E³, substantially as described.
4. The combination substantially as described, with the tube or body of a cork
screw, of the wire puller D) and its seat B.
5. As a new article of manufacture, a cork screw consisting of the tube B and
arm I, the tube B containing a suitable cork extracting mechanism, the window H
opposite the screw, a wire puller attached to the tube B, all operating as and for the
purpose described.
6. The combination substantially as described, within a tube forming the body of a
cork screw, of the collar E, the pins E¹, a suitable stem, handle and screw and the
spiral spring F encircling such stem.
