A NEW OR IMPROVED CORKSCREW
Year: 1884

page_text: I, MARSHALL ARTHUR WIER of 3 Palace Grove Upper Norwood in the County
of Surrey Engineer do hereby declare the nature of my invention for A NEW
OR IMPROVED CORKSCREW to be as follows:-
This instrument is designed to enable corks to be extracted from bottles with
but little effort. It consists of the ordinary screw in conjunction with a series of
compound levers arranged in criscross fashion. Several flat bars of suitable length
and size are placed across each other and rivetted or jointed to each other at their
central parts and also at their ends. To one end of this series of compound levers
a suitable handle is attached which may consist of projecting pins or studs with or
without small handles or a ring may be employed. To the other end of the series
of levers a suitable ring, made to fit onto the neck of an ordinary bottle, is attached
by rivets to the opposite sides of the ring. The lowest middle joint of the series
of levers has the screw attached by means of its rivet.. The boss or that part of
the screw which is hinged to the jointed levers is shaped so that when the series
of levers is closed up the screw will be stiff or incapable of being moved, this is
done by projections arranged upon the boss, the whole instrument will then have:
the appearance of an ordinary corkscrew with a cross handle. The two end levers
of the series also abut against the ring so that it may also be stiff when the instru-.
ment is closed up. To use the corkscrew, the screw is screwed into the cork in the
usual manner, until the ring encloses the top of the neck of the bottle, the series
of levers is then opened by pulling upon the top joint by the handles or ring,
when the compound levers will act upon the screw and extract the cork.

I, MARSHALL ARTHUR WIER of No 3 Palace Grove, Upper Norwood in the
County of Surrey Engineer do hereby declare the nature of my invention for
A NEW OR IMPROVED CORKSCREW and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
Referring to the drawings:
Fig. 1 is a side view shewing the corkscrew partly expanded.
Fig. 2 is a side view shewing the corkscrew closed up.
This instrument is constructed with the ordinary screw or worm A Fig. 1 & 2 in.
conjunction with a serios of compound levers B arranged in criscross manner..
Several flat bars of suitable length & size are placed across each other and riveted
or jointed to each other at their central parts C, and also at their ends D. To one
end of this series of levers a handle is attached, which may consist of projecting
pins or studs with or without small handles or a ring F may be employed. To the
other end of the series of levers a suitable ring G made to fit an ordinary bottle is
attached by the slotted wings G¹G' to each side of the ring G. The lowest middle
joint of the series of levers has the screw or worm A attached by means of its
rivet. The boss, or that part of the screw or worm A. which is jointed to the levers
is so shaped that when the series is closed up the screw or worm will be stiff or
incapable of being moved sideways. This is done by projections. I, I,'arranged
upon the boss or alternatively, by flattening the top part of the boss and by forking
it as shewn at K so that the slot of the fork shall fit or clasp the rivet immediately
above it. The whole instrument when closed up will have the appearance of a
corkscrow with a cross handle as shown at Fig. 2.
The two end levers L, L, of the series of lovers abut against the ring G so that it
may also be stiff when the instrument is closed up.
To use the corkscrew; the screw is screwed into the cork in the usual manner
until the ring G encloses the top of the neck of the bottle, the series of levers is
then opened by pulling upon the top joint by the handle or ring F, when, the force
applied will act through the compound levers and extracts the cork with ease.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
Claim. In the construction of corkscrews the employment of compound levers
arranged in criscross manner substantially as before described and illustrated in
the drawings.
