Improvements in Cork Pullers.
I, JOHN BLACKER BAILY, of Lake Geneva, in the County of Walworth and
State of Wisconsin, United States of America, Gentleman, 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 has relation to an automatic cork puller and the novelty will be
fully understood from the following description and claims when taken in connection
with the annexed drawings in which :
Fig. 1 is a side view of my improved machine showing the same attached to
the top of a bar or other support and in a position ready to draw a cork from a
bottle, and
Fig. 2 is a vertical sectional view of the barrel or cylinder of the device
with the parts in their proper relative position when a cork has been drawn.
Referring by letter to said drawing, A indicates the barrel or cylindrical portion
of my device which normally assumes an oblique position and has formed integral
with it at a suitable point a leg or bracket a, which is suitably provided with screw
holes or the like whereby the whole may be firmly secured to the top of the bar B
or other suitable support.
This cylinder or barrel portion A is provided with an internal seat b, designed to
receive and support a toothed pinion c, which pinion has a central angular hole
or aperture and receives through it the square or flat sided shank d, of the
screw C.
The barrel at this point where the pinion is seated has a lateral slot or opening e,
so that the pinion may project out of the barrel or this lateral slot therein and
receive a reversible rotative movement when engaged by a rack as will be presently
explained.
This barrel is also provided in one of its sides with a longitudinal slot f, for the
play of a plunger g which has swivelled to it the upper end of the screw shaft or
shank as shown at h. By this construction it will be seen that while the screw is
working into the cork it has both a vertical and rotative movement imparted to it,
the rotary motion being given to it through the medium of the pinion c,. while the
vertical movement is received from the plunger.
The pinion may be of the ordinary construction and seated in the banel
in any suitable manner although I prefer to screw-tap the barrel as shown at !,
and employ a threaded nut k, as a bearing for the pinion and means for, keeping it
in position.
Dindicates the operating handle or lever. This handle is pivoted at one end wo
the upper end of the barrel by a. stud or bolt E and a screw 1,.and a plate m,
although it is obvious that the lever may be pivoted or fulcrumed in any, suitable
manner so as to be allowed a rotative movement.
This lever has fixed to it a plate F which carries a heart-shaped wheel or cam
and also a segmental or semi-circular rack and a wire or cord cutter. The lever is
fixed to the upper perpendicular centre of the cam G, and the rack H which is
laterally disposed to engage and rotate the pinion c, describes an arc of a circle the
centre of which is taken from the pivoted or fulcrum point of the lever and the
groove or way n, which surrounds the cam G, receives a friction roller. or lug p,
secured to that portion of the plunger which is disposed through the slot in the
barrel.
On the outer curved face or peripheral portion of the rack H is a cutter I which
is designed to sever the wire which is usually employed in securing corks in bottles.
The barrel is provided with a lug or support K suitably shaped as shown to rest

page_text: upon it the neck of a bottle and this bearing is arranged at a point so that when
the mouth of a bottle has been placed upon it the wire may be severed by the
cutter I from an upward thrust of the lever..
From the construction described it will be observed that the friction roller or
stud on the plunger bears at different times upon opposite sides of the cam groove
or way and as said roller or stud leaves the rack it moves towards the centre or
pivotal point of the cam plate and in.this, latter motion the screw has a straight
lifting movement without rotating.
I prefer to provide the cutter with a file edge although it is obvious that other
forms of cutters may be employed.
In operation, after the bracket a, has been suitably secured to a bar or other
support and it is desired to extract a cork from a bottle having a wire fastening,
the neck of the bottle should first be placed across the lug or bearing A so as to
bring the securing wire in the path of the cutter when the lever is moved so as to
bring the cutter against the wire when the latter will be severed or broken. The
mouth of the bottle is then placed with its cork in the lower end of the barrel or
cylinder, when by an upward thrust of the lever the screw will be forced down and
simultaneously rotated into the cork until the end of the rack has been reached
after which by continuing the throw of the lever the screw and cork thereon will
be given a straight lift out of the bottle. Now by reversing the motion of the
lever the first movement of the plunger and screw will be downward until the rack
strikes engagement with the pinion when both the bottle and cork will be pushed
away from the mouth of the barrel and by continuing the downward movement of
the lever the screw will be rotated and moved upwardly so as to free itself from
the cork.
The barrel may have a flange or lug r, to serve in preventing any lateral
displacement of the rack, and it may also have a grooves, to receive the file or
cutter I.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a cork puller, the combination with a barrel or cylinder of a rotative
reciprocating screw arranged therein having its shank provided with a stud or
friction roller, a pinion on the shank, the hand lever pivoted to said barrel, and a
plate having a heart-shaped cam adapted to reciprocate the screw and also having a
rack adapted to rotate the screw, substantially as specified.
2. In a cork puller the combination with a reversibly rotative and reciprocating
screw provided with a lateral projection, of a plate having a heart-shaped cam
acting on the projection of the screw so as to reciprocate the same and also having
a rack to impart the rotative movements to said screw, substantially as specified.
3. In a cork puller the combination with a barrel or cylinder having a support
above its mouth to receive a bottle neck, of a reciprocating plate pivoted to said
barrel and having a file or cutter on its edge to sever the securing wire of the cork,
substantially as specified.
4. In a cork puller, the combination with a barrel or cylinder having the longi-
tudinal slot therein and the lateral slot at the base of said longitudinal slot, of the
pinion having an angular aperture seated in the barrel so as to be disposed through
the lateral slot, the screw having the angular or flat sided shank and passing
through the pinion, the plunger movable in the longitudinal slot of the barrel and
carrying a laterally disposed stud or friction roller a hand lever pivoted to the
upper end of the barrel, a plate fixed to the lever and having a heart-shaped cam
way receiving the roller of the plunger and also having a curvilinear rack to engage
the pinion and a file or cutter to sever the securing wire of the cork substantially
as specified.
5. The combination with a barrel or cylinder, of the lug K thereon, the pivoted
plute F, and the file 1 on said plate, substantially as specified.

page_text: 6. In a cork puller, the combination with a barrel or cylinder, of a screw
arranged therein and a pivoted plate adapted to impart a rotary and reciprocating
motion to said screw, which motion will be rotary and reciprocative while turning
into and out of the cork, and reciprocative only while raising and lowering the cork,
substantially as specified.
7. In a cork puller, the combination with a supporting frame, of a shaft arranged
therein and carrying a screw, and a pivoted plate having a heart-shaped cam
and adapted to impart alternately to said shaft a rotary and a longitudinally
reciprocating motion, and a non-rotary and longitudinally reciprocating motion,
substantially as specified.
