I, CORNELIUS CHAMBERS, of 13, Great Charles Street, Birmingham, Warwickshire,
Beer Machine Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention as 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 lover, 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 chiefly in
improvements in the mechanism for communicating motion from the hand lever to the
corkscrew and the said invention further consists in the construction of certain other
of the parts of the said machines as herein described.
In carrying out this invention the upper end of the corkscrew is pivotted to a
sliding piece which can work to and fro in a suitable guide preferably forming a con-
tinuation of the barrel in which the sliding nut works. The hand lever is jointed
at one end behind the corkscrew, the free or handle end of the hand lever being free
to move up or down in front of the machine. The hand lever is by preference forked
so as to embrace the guide in which the sliding piece works. Two side links are
jointed to the hand lever and to the sliding piece so as to communicate the
motion of the former to the latter, projecting side pins being provided on the
sliding piece and projecting through longitudinal slots in the guides for the links
to joint on to.
prefer to make the barrel part of the machine in which the corkscrew and sliding
piece work, separate from the foot or base of the machine and to make the foot or
base round and formed with a round pillar to the top of which the said barrel part is
connected in an inclined direction as by so doing the barrel part and the base
and pillar can each be finished by turning which enables the machine to be produced
at a low cost. The said back end of the hand lever is by preference jointed to
the said pillar.

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 corkscrow being screw threaded and working in a non-
rotating nut which is free to slide between stops; and this invention consists chiefly
in improvements in the mechanism for communicating motion from the hand lever to
the corkscrew and the said invention further consists in the construction of certain
other of the parts of the said machines as herein described.
In carrying out this invention the upper end of the corkscrew is pivotted to a
sliding piece which can work to and fro in a suitable guide preferably forming a
continuation of the barrel in which the sliding nut works. The hand lever is
jointed at one end behind the corkscrew, the free or handle end of the hand lever
being free to move up or down in front of the machine. The hand lever is by
preference forked so as to embrace the guide in which the sliding piece works. Two
side links are jointed to the band lever and to the sliding piece so as to communicate
the motion of the former to the latter, projecting side pins being provided on the
sliding piece and projecting through longitudinal slots in the guides for the links
to joint on to.
I prefer to make the barrel part of the machine in which the corkscrew and sliding
piece work, separate from the foot or base of the machine and to make the foot or
base round and formed with a round pillar to the top of which the said barrel part is
connected in an inclined direction as by so doing the barrel part and the base and
pillar can each be finished by turning which enables the machine to be produced at a
low cost.
On the accompanying drawings Fig. 1 is a side elevation of a cork drawing machine
with my invention applied and Fig. 2 is a front elevation of the same; Fig. 3 is a
side elevation of the same in section shewing the parts in the positions which they
occupy when the corkscrew has been screwed into a cork and Fig. 4 shews the same
parts as Fig. 3 in the positions which they occupy when the cork has been withdrawn ;
Fig. 5 represents in side elevation and Fig. 6 in plan the lower part of a similar
machine to that illustrated by the preceeding figures except that it is provided with a
cramp for embracing the edge of a counter or other support, instead of a base for
fixing to the top thereof.
The same letters of reference indicate the same parts in all the figures.
a
is the inclined barrel of the machine supported by the foot b which is fixed to the
counter or other support c. The foot bis by preference circular in plan and is made
separate from the barrel part a and is provided with a round pillar in the top. of
which the projection a¹ on the barrel part fits, a bolt & passing up from the underside
of the foot b and screwed into the projecting part a' secures the base b and the

page_text: barrel a together. e is the sliding piece which is free to slide to and fro in the barrel a
and having pivotted to its lower end the corkscrew f,. The upper part 1 of the
corkscrew is screw threaded of a quick pitch as usual and sliding on the screw threaded
part is the usual non-rotating nut g the motion of which is limited in the usual way
by coming into contact either with the nose h or the reduced part a² of the harrel.
The nut is prevented from turning by the side feathers g' engaging in corresponding
longitudinal slots a³ in the barrel. is the usual removable nose against which the
neck of the bottle is held while the corkscrew is being inserted in the cork and the
cork withdrawn this nose being screwed into the lower end of the barrel a. i is
the forked lever handle by which the corkscrew is operated and which embraces the
barrel a and is jointed at its lower end to a lug j cast at the back of the barrel a.
,, are the two side links which are jointed to the hand lever i and to the sliding
piece e one on either side of the barrel a so as to communicate the motion of the
handle i to the sliding piece e. The screws connect the links to the hand
lever and the links are connected to the sliding piece by the pin m passing
therethrough. The barrel a is slotted at cach side at n n to allow the pin m to
move up or down.
The cork drawing machine above described and illustrated operates in a similar
manner to other cork drawing machines of the same class that is to say upon the
hand lever being pulled downwardly to the position shewn by Fig. 3 the nut g on
coming into contact with the stop h causes the corkscrew to revolve and enter the
cork; on the hand lever heing turned backwardly to the position shewn by Fig. 4
the cork is withdrawn from the bottle and on the nut g coming into contact with the
upper stop in the barrel as shewn the corkscrew is caused to revolve in the opposite
direction and is wormed out of the cork which then falls away through the side opening
in the nose h.
I am aware that prior to my invention cork drawing machines have been made with
a hand lever operating in connection with a corkscrew which is caused to enter extract
and throw off the cork through the forward and backward motion of the said hand
lever I 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 forked lever
handle jointed to the barrel and connected to the said sliding piece by side links
substantially as and for the purposes set forth.
2nd. In a cork drawing machine and in combination with the sliding piece e
rotating corkscrew ff pivotted to the sliding piece e and non-rotating nut g sliding
on the said corkscrew, the forked lever handle jointed to the back of the barrel a
and connected to the sliding piece e by the side links substantially as and for
the purposes herein before described and illustrated by the accompanying drawings.
3rd. In a cork drawing machine and in combination with the barrel having a lever
handle operating an internal sliding piece to which a rotating corkscrew carrying a
non-rotating nut is pivotted, a circular base band pillar secured to a projection a
on the barrel by the bolt & substantially as hereinbefore described and illustrated by
the accompanying drawings.
