Improvements in Cork Extractors.
I, ERNEST SYDNEY RUNDLE, of 14, Macleay Street, Potts Point, Sydney, New
South Wales, Civil Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to an improved cork extractor for bottles containing
beer, wine, or other liquids, and it has for its object to construct a device which
will readily and quickly remove corks from the bottles as aforesaid and also eject
the said corks from the extractor after they have been drawn.
In carrying the invention into effect I provide a tube of suitable material
having at its lower end a bell shaped mouth or guard in which the top of the
bottle is retained whilst the cork is being withdrawn.
Inside the tube is located a corkscrew which may be of the usual spiral form
but having the shank extended and the upper end fixed to one of a train of
spring actuated wheels for which a case is provided, the said wheels being idle
until the insertion of the neck of the bottle into the bell guard aforesaid. Sur-
rounding the corkscrew at a suitable distance from the end thereof is a thin
circular metal tube which tube is connected at its upper end to a spiral spring,
having at its lower end a circular plate working within the outer tube or case,
and which plate is provided with a central opening of sufficient diameter to
permit of the passage therethrough of the tube upon the cork-screw, the tube
being free to slide longitudinally upon the shank of the screw but rotate with it.
The mechanism for rotating the screw may either be put into action by a rod
secured to a suitable clutch, the lower end of the rod coming into contact with
the neck of the bottle when it is introduced into the bell mouth and so releasing
the wheels, or, the spring surrounding the corkscrew may be caused to act upon
a short pin or stud in contact with the end thereof and which stud may be
attached to the clutch aforesaid. The bottle when introduced into the mouth
of the guard first of all comes into contact with the end of the corkscrew and is
pressed thereon, the screw entering a short distance into the cork which next
bears against the plate at the end of the spring releasing the driving mechanism
which thereon causes the screw to rotate, pulling the cork from the bottle, the
neck of which abuts against a suitable projection or ledge in the guard. When
the corkscrew is well into the cork the tube upon the screw comes into contact
with it and rotating with the said screw penetrates the cork, leaving it, when
withdrawn, free to be thrust therefrom by the action of the compressed spring,
the plate secured to the end of which bears upon the cork as aforesaid. When
the cork has been removed from the tube the mechanism stops until a fresh
bottle is inserted and the cycle of operations repeated.

I, ERNEST SYDNEY RUNDLE, of 14, Macleay Street, Potts Point, Sydney, New
South Wales, 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:-
This invention relates to an improved cork extractor for bottles containing
beer, wine, or other liquids, and it has for its object to construct a device which
will readily and quickly remove corks from the bottles as aforesaid and also eject
the said corks from the extractor after they have been drawn.
In order that the invention may be the better understood, drawings are
appended in which:
Fig. 1, is an external view of the cork extractor.
Fig. 2, is a vertical section.
Fig. 3, is a plan with the cover removed, from the case containing the gear
for actuating the corkscrew.
Fig. 4, is a sectional view of part of the gearing for actuating the corkscrew.
Fig. 5, is a plan of Fig. 4.
Fig. 6, is a plan of a clutch.
Fig. 7, is a plan of another portion of the gearing for actuating the corkscrew.
Figs. 8 and 9, are respectively a plan and vertical section of the corkscrew and
the cork cutting device.
I', is a tube of suitable length and diameter and having at its lower end a
bell shaped mouth 2, into which the neck of the bottle is inserted when the cork
is to be removed therefrom, and which mouth is lined with rubber or other
resilient material 3, to prevent damage to the bottles, either when inserted, or
from the pull upon the bottle whilst the cork is being withdrawn.
Inside the tube is a corkscrew 4, of the usual spiral form but having an
extended shank 5, preferably square in section as shown in Fig. 8. The shank
of the screw 4, is provided with a collar 6, which bears against the lower face of
the bottom of the case 7, within which case is situated a train of spring actuated
wheels 8, 9, 10, 11. The wheel 8, is mounted directly upon the shank of the
corkscrew and as shown in the drawings is provided upon its lower face with a
boss 12, in which are cut or otherwise formed recesses 13, designed to be engaged
by dogs or teeth 14, formed upon the upper face of the collar 15, which collar
is mounted upon and free to move vertically of the square sleeve 16, rigidly
secured to the lower plate of the case 7. The collar is bored to permit of the
passage therethrough of the shank 5, which is of circular section above the
collar 6. The collar 15, is normally held in contact with the boss 12 by means
of the light spiral spring 17, Fig. 2, until released either by means of the
button 18, actuated by the finger or by the stud 19, actuated by means of a
spring 20, the purpose of which will be hereafter fully described, in either case
the upward pressure of the button and stud acts in the one case directly upon
the end of the lever 21, pivotted at 22, and in the other the movement of the
stud is transmitted by the arm 23, secured thereto, to the end of the lever 21,
with which the said arm is in contact. The lever 21, is provided at its end with
a small projection 24, which engages with a recess formed in the collar 15, see
Fig. 2. In gear with the wheel 8, is the wheel 9, fixed to the spindle 25, to
which is also secured the larger wheel 10, in gear with the wheel 11, mounted
upon the sleeve 26, secured in any suitable manner to the upper plate of the
case 7. Forming part of or secured in any suitable manner to the wheel 11,

page_text: is a circular case 27, see Figs. 2 and 4, within which is situated the coiled
spring 28, one end of the spring being attached to the sleeve 26, and the other
being attached to the case 27. It will be seen from the foregoing description
that the spring 28, being coiled up that when the clutch is withdrawn from
engagement with the recesses in the wheel 8, that the tendency of the spring
will be to uncoil itself, turning the case 27 and with it the wheel 11, thereby
actuating the wheels 10 and 9, the last of which wheels transmitting motion to
the shank of the corkscrew which will thereupon be caused to rotate. Encircling
the corkscrew is the spiral spring 20, before referred to, the upper end bearing
against the stud 19, and its lower carrying the plate 29, which plate is slightly
smaller than the bore of the tube 1, having upon its lower face a disc of rubber
or the like 30, both plate and disc having an opening for the corkscrew and
having pins 31, which engage with slots 32, forined in the tube 1, as shown in
Figs. 1 and 2. Inside the spring 20, and surrounding the corkscrew is a sleeve 33,
of steel or other suitable material which has formed at its upper end a collar 34,
and also a square hole for the shank of the screw, see Figs. 8 and 9. Com-
pressed between the collar 34, and the collar 6, is a spring 35 of such strength
to allow of the sleeve 33, being forced up as the screw enters the cork and at the
same time give sufficient pressure for the teeth or serrations formed at the end
of the sleeve to gradually cut or bore the cork so that by the time the screw is
well through the cork and has withdrawn it from the bottle, the sleeve has cut
its way through the cork, leaving it free when the bottle is withdrawn to be
ejected from the tube by the spring 20. The train of wheels herein described
may be arranged either in the manner shown, or it may vary either in the
number of wheels employed or the method of their arrangement according as
it will in practice be found most effective for the purpose.
For the purpose of attaching the device to a bar or other convenient place, I
provide lugs 36, Fig. 1, through which screws or the like may be passed.
The winding of the device is effected by means of the fly nut 37, the button 18
being pressed by the finger thereby freeing the wheels and allowing the spring
to be wound up.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:
The combination and arrangement of parts forming a cork extracting device
constructed and operating substantially as herein set forth and illustrated by
the appended drawings.
