A communication from JOSEPHI HENRY STANTON, of Sydney, in the Colony of
New South Wales, Commercial Manager,
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, 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 been specially devised for the purpose of doing away with
the spike attachment to the handles of corkscrews, such spike being used specially
for breaking the wire which is sometimes used to retain the cork in the bottle.
The invention consists in attaching to the shank of the corkscrew, immediately
above the worm, a steel disc the edge of which is tangentially slit, the slit or
segmental part being turned down so as to provide a cutting edge. When the
worm is screwed home into the cork, the handle is given another turn and the
edges of the turned down parts will cut or break the wire. The disc may be
screwed on to the shank, or the shank may be made square so as to fit into a
corresponding square hole in the disc.
In the accompanying drawings:
-
Fig. 1 is an elevation of a corkscrew fitted with the wire cutting appliance,
which in this case is screwed on to the shank.
Fig. 2 is an underneath plan of the disc separated from the corkscrew.
Fig. 3 is a similar view, but with the disc provided with a square hole to fit
on to a corresponding square on the shank of the corkscrew.
a is the handle, b the shank, which at the point c where it merges into the
worm may be provided with a thread as shewn in the drawing, on to which the
disc d may be screwed, or the part c may be made square so as to fit the square
hole e in the disc as shewn in Fig. 3. The disc d is tangentially slit as shewn
in Figs. 2 and 3 and the slit or segmental parts g are turned down so that the
cutting edges of these turned down or segmental parts g will be turned in the
direction of rotation of the corkscrew, and thus, when the worm is entirely embedded
in the cork another turn of the corkscrew will cause the cutting edges of the turned
down or segmental parts g to cut or break the wires which overlie the cork.
The disc may be made with one or several tangential slits. In the drawing,
three of such slits are shewn. The hole in the disc, which is threaded on to the
shank, may be re-inforced or strengthened by a boss as shewn at f which will give
it a better grip on the shank.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is:-
1. In corkscrews, a disc placed immediately above the worm of the corkscrew,
such disc being tangentially slit in one or more places and the segmental part
thus partially cut off, being turned down in order to provide an edge for cutting
or breaking the wire which sometimes overlies the cork, as specified.

page_text: 2. In combination a corkscrew and a disc which is tangentially slit in one or
more places and the slit off or segmental parts being turned down, such disc
being secured to the shank, as herein-set forth and for the purposes specified.
