Certain Improvements in Cork Drawing Machines.
I THOMAS JOSEPH HASLAM of 105 Middle Abbey Street, Dublin Brass
Founder and 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 a cork and consists firstly in
improvements in the mechanism for communicating the motion by the hand lever
to the corkscrew and cork extractor. Secondly, in improvements in the mechanism
for extracting the cork from the bottle and the said invention consists of further
improvements in certain other parts of the machine as hereinafter described.
In carrying out this invention prefer to make the hand lever and lever which
conveys the motion to the corkscrew in one piece the hand lever being free to move
up and down on one side of the machine. After the screw has entered the cork the
hand lever is so formed that it comes in contact with a roller fixed to the top of a
rod which carries at the other end an arrangement preferably a fork to take the
neck of the bottle this rod being free to move up and down in a groove on one side
of the machine and the fork can be adjusted on the rod to draw any desired length
of cork.
Fig. 1. in the accompanying drawings represents a sectional view of the cork
drawing machine showing my improvements applied.
Fig. 2, is a sectional view of the piston, d, showing the roller c, and the
projection, n.
Fig. 3, is a front view of the hand lever, a, and lever b, showing the crank r.
Fig. 4, represents the fork /, secured to the rod k by the binding screw t.
Referring to Fig. 1, the hand lever, a, may be made continuous in one piece with
the lever b, and cranked at r so as to allow the hand lever to move up and down
on one side of the machine the hand lever being pivotted at p.
c, is a wheel free
to revolve on an axle inside the piston, d, and is provided to reduce as far as
possible the friction caused by the lever when forcing the piston d downwards and
so causing the screw g to enter the cork. The leading screw e imparts the rotating
motion to the corkscrew, g, by means of the nut, f, which in this machine is fixed.
The rod, k, is free to move up and down in the groove, s, the fork, l, which takes
the neck of the bottle is adjustable on the rod, k, which is held in its position by the
spring, m. The projection, n, on the piston, d, works in a longitudinal slot in the
under side of the barrel of the machine and prevents the piston, d, from turning,
round and is also used for the purpose of raising the piston in the barrel when
operated upon by the lever, 4, on the return stroke of the hand lever, a.
In this machine the screw is driven into the cork by pulling the hand lever, a,
Fig. 1, forward, this causes the lever, b, to press upon the roller, c, and forces the
When the screw has
piston, d, to descend and drive the screw, y, into the cork.
thus been driven home the lever, h, is free to turn out of the barrel of the machine.
Continuing the downward pull of the hand lever, a, the rounded part, h, now comes
in contact with the roller, j, on the top of the sliding rod, k, causing it to descend
when the bottle is drawn off the cork by reason of the fork, l, pressing downwards
against the neck of the bottle, the cork being left hanging on the screw, g. On
returning the hand lever, a, to its former position the lever, b, enters the slot in
the underside of the barrel and coming in contact with the projection, n, on the
piston, d, raises it, thus causing the screw, g, to be withdrawn from the cork which
falls away. The spring, m, at the same time lifts the sliding rod, k, up to its former
› position.

Having now particularly described and ascertained the nature of
tion and in what manner the same is to be performed I declare that what I
claim is :-
:―
1
1st. In a cork drawing machine the hand lever, a, and lever, b, free to work clear
of the piston, d, substantially as and for the purposes set forth.
2nd. In a cork drawing machine and in combination with the piston, d, the
roller, c, and projection, u, substantially as and for the purposes set forth.
3rd. In a cork drawing machine the sliding rod, k, having the roller, j, attached
at one end and the fork, l, attached at the other end substantially as and for the
purposes set forth and hereinbefore described and illustrated by Figs. 1, 2, 3 and 4
of the accompanying drawings.
4th. In a cork drawing machine of this construction Fig. 1, corks of any length
can be extracted and discharged with ease and owing to the cork being extracted
in the downward pull of the hand lever great rapidity is obtained, the absence of
links or other connections between the lever and piston allows greater freedom of
access to all parts of the machine and the thrust being direct on to the roller in the
piston great power is gained and friction minimised.
