IMPROVEMENTS IN CORKSCREWS
Year: 1884

page_text: I, STEPHEN PLANT, of the firm of W, and J, Plant, of 105, Poole Street,
Wolverhampton, in the County of Stafford, Corkscrew and Steel Toy Manufacturers,
do hereby declare the nature of my invention for, IMPROVEMENTS IN CORKSCREWS,
to be as follows:-
This invention relates to the type of corkscrew in which the cork is drawn (after
the screw proper is screwed therein) by means of a handle screwed upon the shank
of the corkscrew.
In this type of corkscrew the screwed shank passes easily through the top of a
frame which rests upon the neck of the bottle from which a cork is to be drawn.
The handle by which the screw proper is screwed into the cork is prevented from
turning whilst being used for this purpose, and is then screwed on the shank so as
to raise such shank through the frame and consequently draw the cork.
Now the object of this invention is to provide more simple and efficient means,
than those hitherto employed, for preventing the handle from turning upon the
shank as the screw proper is screwed into the cork and for afterwards releasing
such handle so that it may be used to screw up the shank to draw the cork.
This object is effected by inserting a sliding plate within the upper part of the
handle, so as to be capable of sliding endways therein, to cover the end of the
screwed shank when desired, and connecting a stud to the upper side of such plate
by which it may be slid inwards over the end of the shank and outwards so as to
be clear of the shank. A slot is formed through the metal of the handle
immediately above the plate, for the necessary distance from the central hole
outwards, to receive the stud when the sliding plate is pushed back clear of the
shank. The sliding plate is slit down, for a part of its length, near one side, from
its inner end, to form a strip of metal to act as a side spring and produce sufficient
friction to prevent the sliding plate from being shaken or too easily moved from
any desired position.
When the plate is slid over the end of the shank the handle cannot of course be
screwed up thereon; but when it is slid back therefrom the handle is free for this
purpose.

page_text: I, STEPHEN PLANT, of the firm of W. and J Plant, of 105, Pool Street,
Wolverhampton in the County of Stafford, corkscrew and steel toy manufacturers
do hereby declare the nature of my invention for IMPROVEMENTS IN CORKSCREWS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being bad to the accom-
panying drawings and the letters of reference marked thereon :—
This invention relates to the type of corkscrew in which the cork is drawn (after
the scrow proper is screwed therein) by means of a handle screwed upon the shank
of the corkscrew.
In this type of corkscrew the screwed shank passes easily through the top of a
frame which rests upon the neck of the bottle from which a cork is to be drawn. The
bandle by which the screw proper is screwed into the cork is prevented from
turning upon the shank whilst being used for this purpose, and is then screwed on
the shank so as to raise such shank through the frame and consequently draw
the cork.
Now, the object of this invention is to provide more simple and efficient means,
than those hitherto employed, for preventing the handle from turning upon the
shank as the screw proper is screwed into the cork, and for afterwards releasing
such handle so that it may be used to screw up the shank to draw the cork.
This object is effected by inserting a sliding-plate within the upper part of the
handle (or carrying it in a slide upon such handle), so as to be capable of sliding
endways therein to cover the end of the screwed shank, when desired, and also to
uncover such end, and connecting a stud to the upper side of such plate by which it
may be slid inwards over the end of the shank and outwards so as to be clear of
the shank, or providing other convenient means for moving such sliding-plate
endways. A slot is formed through the metal of the handle immediately above the
plate, for the necessary distance from the central hole outwards, to receive the stud
when the sliding-plate is pushed back clear of the shank. The sliding-plato is slit
down, for a part of its length, near one side, from its inner end, to form a strip of
metal to act as a side spring and produce sufficient friction to prevent the sliding-
plate from being shaken or too easily moved from its desired position.
When the plate is slid over the end of the shank, the handle cannot of course be
screwed up thereon; but when it is slid back therefrom the handle is free for this
purpose.
My invention will be very clearly understood by reference to the accompaning
drawings, of which figure 1 is an elevation, and figure 2 a plan of a corkscrew
having my invention applied thereto. A is the frame which. rests upon the neck
of the bottle from which a cork is to be drawn. B is the screw proper which enters
the cork, C is the screwed shank of the screw proper B, and D is the handle. The
screwed shank C passes through a plain cylindrical hole in the boss E at the top of the
frame A, and is screwed through the handle D. F is a sliding-plate fitted to slide in
an opening or guide formed therefor in the upper part of the handle D, and G. is a
stud screwed into such sliding-plate, and by which it is moved endways as desired.
A detached plan of the plate F is shewn at figure 3, in which H is a narrow strip
of metal slit down and set out somewhat, as shewn, so as to form a side spring to
bear against one side of the opening or slide in the handle and maintain the plato
in its desired position.
When it is desired to screw the screw proper B into a cork to be drawn, the
handle D is screwed back along the shank C sufficiently to enable the sliding-

page_text: plate F to be slid inwards over the end of the shank C. By this means the
handle D is prevented from being screwed along the shank C, as the sliding-plato F
forms a stop thereagainst; and the screw proper B may thus be turned by the
handle D. After the screw proper B has been screwed sufficiently into the cork,
the sliding-plate F is slid back into the position shewn by figures 1 and 2, when
the handle may be screwed upon the shank C so as to raise it up through tho
boss E and thus draw the cork. a is a slot running back from the central hole
through the handle D, into which the stud G is pulled to bring the plate F into its
outward position, as shewn by figures 1 and 2. This slot does not run out to tho
exterior of the boss of the handle, but forms a stop at its outward end to the
backward movement of the stud G and consequently of the plate F.
I am aware that the closing of the opening through the outer or upper face of the
handle of a corkscrew, of the type herein described, in order to prevent the handle
from turning on the screwed shank, has been effected before, but in a different
manner to that herein described, and I do not therefor make a general claim for this
purpose.
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 :-
1. In the type of corkscrew herein described and illustrated by the drawings, &
sliding plate capable of an endway movement in a slide or guide in or upon the
handle, substantially as and for the purpose herein described and shewn by the
accompanying drawings.
2. In the type of corkscrew herein described and illustrated by the drawings, a
sliding-plate carried within the metal of the handle in combination with a stud
projecting therefrom and a slot in the handle to receive such stud, substantially as
and for the purpose herein described and shewn by the accompanying drawings.
3. The sido spring H slit along the plate F, substantially as and for the purpose
herein described and shown by figure 3 of the accompanying drawings.
Dated this nineteenth day of December 1884.
