PROVISIONAL SPECIFICATION.
Improvements in Corkscrews.
I, JOHN MERCER, of 16 Ann Street, Glasgow, Lanarkshire, North Britain,
Commission and Cigar Merchant, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in corkscrews, and is more especially
applicable for extracting the corks from bottles containing aërated waters and
other liquors which necessitate the cork being held down by means of a wire.
The invention consists in fixing to the screw at a convenient distance from the
point thereof a sort of cup having serrated edges so that when the screw enters the
cork a certain distance the serrated edges come in contact with the wire, and
the screw being still turned, the wire is nipped or broken and the cork is then
easily extracted.
Dated this 9th day of December 1891.

COMPLETE SPECIFICATION.
Improvements in Corkscrews.
I, JOHN MERCER, of 16 Ann Street Glasgow, in the County of Lanark, North
Britain, Commission and Cigar Merchant, 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 :-
My invention relates to improvements in corkscrews, and is more especially
applicable for extracting the corks from bottles containing aërated waters and
other liquors which necessitate the cork being held down by means of a wire.
My invention consists in fixing to the screw at a convenient distance from the
point thereof a sort of cup having serrated edges so that when the screw enters the
cork a certain distance the serrated edges engage with the wire, and the screw
being still turned, the wire is nipped or broken or displaced whereby the cork is
easily extracted.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings, in the several
figures of which corresponding parts are marked with the same letters of reference.
Figure 1 is a front elevation showing my improvements.
Figure 2 is an inverted plan.
Figure 3 is a view showing a person in the act of withdrawing a cork from a
bottle with my improved corkscrew.
Figure 4 is a broken view of a bottle showing the wire cut after the cork has
been withdrawn.
A is the corkscrew, B is the butt, and C is the handle. D is the cup having
serrated edges e, which cup is fixed to or forms part of the butt B.
When it is desired to extract a cork from a bottle the bottle is held in the hand
and the point f of the screw F which is made almost straight in order to more
readily break or split the wooden top sometimes placed over the cork, is inserted
into the cork E and then the screw is turned. When it has entered the cork a
certain distance the serrated edges e of the cup D engage with the wire g, and the
screw F being still turned the wires are nipped or broken or displaced, thus enabling

page_text: the cork to be easily withdrawn as seen more particularly in Figures 3 and 4, with-
out wasting the time usually consumed in undoing the wire and taking off top.
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 :-
1
In corkscrews a cup having serrated edges fixed to or forming part of the butt of
the screw, substantially as and for the purposes hereinbefore described and shown
on the accompanying sheet of drawings.
Dated this 6th day of April 1892.
