Certain Improvements in Cork-drawing Machines.
1, CORNELIUS CHAMBERS, of 13, Great Charles Street, Birmingham, Warwickshire,
Beer Machine Manufacturer, do hereby declare the nature of this invention to bo
as follows:-
:-
This invention has reference to that class of cork-drawing machines in which a
corkscrew is caused to enter, extract and throw off the cork through the back ward
and forward motion of a hand lever, the rotary motion of the corkscrew being obtained
by the upper part of the corkscrew being screw threaded and working in a non-
rotating nut which is free to slide between stops; and this invention consists firstly
in improvements in the arrangement of the hand lever and its connections for
communicating motion to the corkscrew, and secondly in an improved thrust bearing
and connections at the upper end of the rotating corkscrew where it is attached to the
sliding piece. The first part of my said invention is carried out as follows:-The
hand lever is hinged at one end below the barrel containing the corkscrew and the
sliding piece to which the corkscrew is pivotted, the handle end being free to move.
up or down in front of the machine. The hand lever is forked so as to embrace the
said barrel and is preferably hinged to the stand or pillar by which the barrel is
supported. Motion is transmitted from the hand lever to the sliding piece to which
the corkscrew is pivotted by a link or connecting rod which is jointed to the hand
lever and to the sliding piece, an upper projecting part being provided on the sliding
piece which works through a longitudinal slot in the upper side of the barrel; or the
said link may be jointed to a lower projecting part on the sliding piece and to the
hand lever between the barrel and the fulcrum of the hand lever, a longitudinal slot
being provided in the underside of the barrel for the said lower projecting part to
work in.
In order to reduce as far as possible the friction between the upper end of the
revolving corkscrew and the sliding piece to which it is pivotted I provide a hard
metal ball (preferably of hardened steel) between the upper end of the corkscrew and
the lower end of the sliding piece these parts being cupped out to receive the said
ball. The upper end of the corkscrew is by preference reduced in diameter to about
D

page_text: the diameter of the ball and a short distance from this reduced part is a collar, these
parts fitting in corresponding recesses in the lower end of the sliding piece where
they are retained but allowed to revolve by a cap which is threaded on the corkscrew
and screwed on to the lower end of the sliding piece. This method of construction
enables the corkscrew to turn very easily and considerably reduces the wear on these 5
parts.
I, CORNELIUS CHAMBERS, of 13, Great Charles Street, Birmingham, Warwickshire,
Beer Machine Manufacturer, 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 reference to that class of cork drawing machines in which a
corkscrew is caused to enter, extract and throw off the cork through the backward
and forward motion of a hand lever, the rotary motion of the corkscrew being
obtained by the upper part of the corkscrew being screw threaded and working in a
non-rotating nut which is free to slide between stops; and this invention consists
firstly in improvements in the arrangement of the hand lever and its connections for
communicating motion to the corkscrew, and secondly in an improved thrust bearing
and connections at the upper end of the rotating corkscrew where it is attached to
the sliding piece. The first part of my said invention is carried out as follows:-The
hand lever is hinged at one end above the barrel containing the corkscrew and the
sliding piece to which the corkscrew is pivotted, the handle end being free to move up
or down in front of the machine. The hand lever is forked so as to embrace the said
barrel and is preferably hinged to the stand or pillar by which the barrel is supported.
Motion is transmitted from the hand lever to the sliding piece to which the corkscrew
is pivotted by a link or connecting rod which is jointed to the hand lever and to the
sliding piece, an upper projecting part being provided on the sliding piece which
works through a longitudinal slot in the upper side of the barrel; or the said link
may be jointed to a lower projecting part on the sliding piece and to the hand lever
between the barrel and the fulcrum of the hand lever, a longitudinal slot being
provided in the underside of the barrel for the said lower projecting part to
work in.

page_text: On the accompanying drawings Fig. 1 represents in sectional side elevation a cork
drawing machine embodying my improvements; Fig. 2 is a longitudinal section of
the barrel part of the same looking from the front of the machine; Fig. 3 is a modi-
fication of the same; Fig. 4 represents in side elevation and Fig. 5 in longitudinal
section a further modification of the same; Figs. 6 and 7 illustrate how I form the
ball bearing at the top of the corkscrew, and Fig. 8 shews the nut for the corkscrew
separately.
The same letters of reference indicate corresponding parts in all the figures of the
drawing.
Referring firstly more particularly to Figs. 1, 2, 3 and 8, a is the hand lever hinged
at one end to the bracket b formed with the barrel and the stand or screw cramp f
by which the machine is fixed to the counter or other support g.
This bracket may
either be formed at the front of the machine as shewn by Fig. 1 or at the back of
the machine as shewn by Fig. 3. In the barrel c is the sliding piece to which the
corkscrew e is pivotted. is the link which is jointed to the lever a and to the
sliding piece d'so as to communicate motion from the former to the latter. d¹ is
the upper projecting part of the sliding piece d which works in a longitudinal slot i in
the upper side of the barrel so as the better to prevent the sliding piece d having
any tendency to turn round but if preferred this projecting part d' and slot i may be
dispensed with. The nosej, corkscrew e and sliding nut & are of the usual well known
form the nut being prevented from turning by the side feathers ¹ engaging in
corresponding longitudinal slots in the barrel the upper part of the slots forming
stops for preventing the nut rising too high.
In the modification illustrated by Figs. 4 and 5 the link his jointed to a lower
projecting part d² on the sliding piece d and to the hand lever a between the barrel c
and the fulcrum a¹ of the hand lever, a longitudinal slot being provided in the
barrel for the lower projecting part d² to work in.
In the example illustrated by Fig. 1 the corkscrew is wormed into the cork by
pushing the handle and the cork is withdrawn from the bottle and the cork thrown
off the corkscrew by pulling the handle; in the examples illustrated by Figs. 3 and 4
the operation of the handle is the reverse of this, that is to say, the handle is
pulled to rotate the corkscrew into the cork and pushed to withdraw the cork from
the bottle and throw off the cork from the corkscrew.
In order to reduce as far as possible the friction between the upper end e¹ of the
corkscrew and the sliding piece d I provide a hard metal ballo (preferably of
hardened steel) which is placed between the upper end of the corkscrew and the
lower end of the sliding piece (see Figs. 6 and 7) these parts being cupped out to
receive the ball o. The upper end e¹ of the corkscrew is by preference reduced in
diameter to a little larger than the ball o and a short distance from this reduced
part is formed a collare these parts fitting in corresponding recesses in the lower
end of the sliding piece d where they are retained (but allowed to revolve) by the
cap p which is threaded on to the corkscrew e and screwed on to the lower end of
the sliding piece. This method of construction enables the corkscrew to turn very
easily and considerably reduces the wear of these parts.
I am aware that prior to my invention cork drawing machines have been made
with a hand lever operating in connection with the corkscrew which is caused to
enter extract and throw off the cork by the forward and backward motion of the
said hand lever, 1 therefore do not claim such a combination broadly but,
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 :-
1st. In a cork drawing machine and in combination with the sliding piece to which
a rotating corkscrew carrying a non-rotating nut is pivotted, the lever handle jointed
to the barrel and connected to the said sliding piece by a link working in the
open top of the barrel substantially as and for the purposes set forth.
2nd. In a cork drawing machine and in combination with the sliding piece d

page_text: rotating corkscrew e pivotted to the sliding piece d and non-rotating nut k sliding

as hereinbefore described and illustrated by Figs. 4 and 5 of the accompanying
drawings.
4th. In a cork drawing machine and in combination with the sliding piece and
the rotating corkscrew, the ball o fitting between the sliding piece and the rotating
corkscrew these parts being adapted to receive the same substantially as set forth.
5th. In a cork drawing machine and in combination with the sliding piece d and
the rotating corkscrew e, the ball o fitting between the sliding pieced and the rotating
corkscrew these parts being adapted to receive the same and secured together by
the cap p substantially as hereinbefore described and illustrated by Figs. 1, 6 and 7 of
the accompanying drawings.
