IMPROVEMENTS IN CORKSCREWS
Year: 1884

page_text: HENRY JAMES PERRY Cutler &° 156 North St Brighton Sussex do hereby
declare the nature of my invention for. IMPROVEMENTS IN CORKSCREWS to be as
follows:-
Fig 1. represents the screw whilst being driven into the Cork, Fig 2, section of
same whilst extracting the Cork, the screw is driven into the Cork in the usual
way by turning the handle from left to right and the Cork is extracted by turning
the handle from right to left, in fig 2. there are two flanges shown on Box A, these
are pull'd into slots in Plate B. by a spiral spring whilst being screw'd into the
Cork, but immediately the handle is reversed these flanges are withdrawn allowing
the handle & stem C. to revolve independently of the screw D. which remains
firmly in the Cork ensuring a direct steady pull.

page_text: I HENRY JAMES PERRY trading as English & Sons Cutlers &, 156 North Street,
Brighton Sussex do hereby declare the nature of my said Invention for "IMPROVE-
MENTS IN CORK SCREWS," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of my invention is to manufacture an improved cork screw. for
extracting corks from bottles.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
.similar letters of reference indicate corresponding parts.
Fig. 1 is an external elevation, and Fig. 2 is an elevation, partly in section.
a, a is an open frame, of the. usual form, the lower end a' of which is formed to
encircle the upper end of the neck of the bottle as shewn in Fig. 4. b is a screw
with a coarse pitch (usually a four-threaded screw) the head of which is fitted
with an ordinary handle f for turning the same. The external screw on b fits an
internal screw cut in the upper part or collar of a at a².
The lower end of 'b is bored out and is fitted with a short cylinder c, (shewn in
section in Fig. 2) which rotates therewith. The lower end of this cylinder is fitted
with two ratchet teeth at c which come in contact with and drive two corresponding
teeth d attached to the screw d¹. A spindle is also formed in one with the
screw d¹, as shewn in Fig. 2. A spring e surrounds the spindle d², which tends to
keep the clutch in gear, except when the cork is being withdrawn.
When the screw d¹ is inserted into the cork, the handle is simply tarned "right
-handed," the descent of band d¹ being simultaneous, and the clutch being in gear
during such descent of the screws. On reversing the motion of the handle, the
screw b begins to draw the cork, and the spring e yields to the draught; by which
action the clutch is released as shewn in Fig. 2, and the screw b revolves in a left
handed direction without turning the screw d³, which is simply drawn upwards
with the cork.
In some cases I fit a loose nut a³ which is tapped to fit the screw b;
in this case, being left banded.
the screw,
When the nut is raised on the screw b, as shewn in Fig. 3, the screw b is free to
revolve and slide in the collar a²; but when the nut is lowered to the position
shewn in Fig. 4, the continued turning of the screw (right handed) draws up the
screw d¹, and with it the cork g from the bottle (Fig. 4) the two teeth or
ratchets i coming in contact. with the corresponding ratchets k on the collar a² to
prevent the nut a³ from turning.
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
The construction of cork screws, consisting of a main screw b, driven by the
handle f, working in the collar a³ or loose uut a³, and operating the screw d¹ by

one direction only; the screw d¹ becoming automatically disengaged from the
clutch when withdrawing the cork; substantially as described and shewn on the
drawings.
