COMPLETE SPECIFICATION (AMENDED).
Improvements in Cork Extractors.
BEARDSLEY GILCHRIST, of 367 Cleveland Avenue, Chicago,
Illinois, United States of America, 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 relates to an improvement in the class of cork-extractors adapted
to be fastened in operative position on a stationary support and having its screw
provided with actuating means for first driving it into the cork of a bottle presented
to the device, then withdrawing the cork and finally stripping it from the screw.
The particular variety of cork-extractor to which my present improvement relates
involves a case containing a vertically reciprocating plunger operatively connected
with the actuating handio and carrying the rotatable screw which works in and is
turned by a non-rotatable nut.
The primary object of my invention is to enable the two contrary movements, or
the reciprocation, of the screw-carrying plunger to be produced by a continued
motion in one direction of the operating handle; and my further object is to provide
details of construction especially well adapted for causing the several operations of
cork penetrating, pulling and stripping to be produced by the plunger being caused
to reciprocate in the manner stated.
Referring to the accompanying drawing —
Figure 1 is a view showing my improved cork-extractor in sectional elevation, one
side of the case being removed to display the contained mechanism, the parts of
which are represented in their normally relative positions prior to the insertion of
the screw into a cork. Figure 2 is a view like that presented in Figure 1, but
showing the parts of the mechanism in their relative positions assumed on extracting
a cork.
A is a case, of metal and of any suitable form, though preferably that shown
and involving a tubular portion terminating at its lower end in a flaring socket y,
in which to seat the corked end of a bottle, and a crown p having flattened sides
and more or less oval in vertical section between the sides. At one side of the case
is provided a clamp-device for fastening the extractor in operative position, as to
the edge of a table or counter, and which I show as a bracket o having a clamp
screw n working in a nut in its arm m.
C is a nut fitting in the tubular extension of the case A and capable of being
moved back and forth therein, but confined against rotary movement, as by a stop
extending into a slot in the side of the case. Above the nut in the tubular part »
is a plunger D carrying the rotary cork-screw E which is shown as having a cone-
shaped head seated in a recess i formed with an opening in its base, so that the
cork-screw E can be inserted obliquely in the opening and may be turned obliquely
downward until the head k enters the chamber i when the cork-screw E drops into

page_text: Thus
a vertical position and is held against vertical movement independent of the
movement of the plunger with which it reciprocates, but is free to rotate.
the screw E is centered in the plunger and works in the screwed opening through
the nut C in the manner hereinafter described.
In the crown p and carried on a pivot or centre c is confined a head F, preferably of
disc-shape and of a diameter to extend at its circumference through a slot d about the
rounded edge of the crown-portion of the case. The operating handle H is connected,
in any suitable manner, with the head F and preferably by being cast therewith to
extend tangentially from it, and work in the slot d. From one side of the pivot c,
the head F is connected with the upper end of the plunger D by a link G or
connecting rod, pivoted at its opposite ends respectively to the head and plunger.
I is a stop-rod, fastened at one end to the nut C, and extending thence upward in
the casing (freely passing the plunger D through a longitudinal notch in one side)
into the crown between guide-lugs and projecting at its upper end into the path of
an arc-shaped cam K on one side of the disc F near its periphery.
The operation is as follows:
With the device operatively fastened in place and its parts in the relative
positions in which they are illustrated in Figure 1, the extractor is in condition to
work on a bottle forced at its corked end against the seat q. Then, by raising the
handle H to turn the disc F on its centre, the link G forces the plunger D downward
and with it the screw E which rotates when passing through the nut C and entering
into the cork. The plunger will reach its lowest position and the screw its fullest
depth of penetration into the cork when the head has been turned far enough to.
bring the link on a dead centre. By continuing the movement of the handle to the
position in which it is illustrated in Figure 2, the head will carry the link past
the centre and up to an elevated point at the side thereof opposite that from which
it started. The upward movement of the link draws up the plunger D and as the
cam K has left the top of stop rod I said rod and nut C are free to rise, and as
there is a certain amount of friction between screw E and the cork they rise with
the plunger, thereby pulling the cork with the nut and plunger into the case A.
For stripping the extracted cork from the screw the handle H is turned back and
lowers the plunger and the nut C and rod 1 to their lowest point in the tubular part r
of the case, (where the nut is arrested by the stop 1), at which point the link G is
again on a dead centre. Then the end of the cam K is in position over the upper
end of the rod and the nut is held against rising while the link passes beneath the
centre c on its way to the position in which it is shown in Figure 1. The nut C
being thus held stationary, the raising of the plunger D with reference to it pulls
the screw E through the nut and turns it in the direction to unscrew it from the
cork and thus strip the latter.
As will be seen, therefore, by turning the handle from one side to the other,
the plunger is reciprocated, causing the screw to first penetrato the cork and
then withdraw it from the bottle; and the same two motions are imparted to
the plunger by turning the handle back again, with the effect of first returning the
nut to and locking it in its normal lowered position and then turning the screw out
of the cork.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed [ declare that what I
claim is ;--
1. In a cork-extractor, a reciprocable plunger carrying a rotatable screw,
a reciprocable nut for the screw, a rotable head provided with an operating handle
and having an eccentric connection with the plunger, and stop mechanism engaging
the nut to lock it, substantially as and for the purpose set forth and illustrated in the
accompanying drawings.
2. In a cork-extractor, a reciprocable plunger carrying a rotatable screw, a
reciprocating nut for the screw, a rotable head provided with a cam and an operating
handle and having an eccentric connection with the plunger, and a nut-stop

page_text: extending into the path of the cam, substantially as and for the purpose set forth
and illustrated in the accompanying drawings.
3. In a cork-extractor, a reciprocable plunger carrying a rotatable screw, a
reciprocating nut for the screw, a disk-shaped head F rotably supported on a center e
and provided with a cam K, a link G connecting the plunger with the head to one
side of its center, an operating handle on the bead to rotate with it, and a stop-rod I
extending from the nut into the path of the cam, substantially as and for the purpose
set forth.
4. A cork-extractor comprising, in combination, a case A having a flat-sided
oval-shaped slotted crown p provided with a tubular extension having a slot l, a
head F rotatably supported in the crown and having a handle H, and a cam K, a
reciprocable plunger in the said tubular extension, a screw E having a conical head
rotably confined in a conical socket in the base of the plunger, a nut C reciprocably
confined in said extension and having a stop protruding into the slot 1, a link G
connecting the plunger eccentrically with the head, and a stop-rod I fastened
at one end to the nut and extending thence upward into the path of the cam,
the whole being constructed and arranged to operate substantially as described.
5. In a cork-extractor, the combination with a suitable case, of a plunger free
to slide longitudinally therein, means for reciprocating the plunger in the case and a
cork-screw adapted to be inserted in or removed from the plunger in a line oblique
with reference to the line of movement thereof and when inserted and brought into
the line of movement of the plunger to be secured against longitudinal movement
with reference thereto, substantially as described.
