PROVISIONAL SPECIFICATION.
Improvements applicable to Stoppers for Bottles, Jars, and the like.
I, GERARD COLLINGWOOD CLARK, of 4, Ashland Place, in the County of
London, Manufacturer, do hereby declare the nature of this invention to be as
follows:--
My invention relates to that class of stoppers described in my former Letters
Patent No. 10762 dated the 3rd of July 1889 and to the means for withdrawing
such stoppers from bottles or jars forming the subject of my former Letters
Patent No. 16592 of the 21st October 1889.
I have found in practice that in order to make my stoppers having a screw
threaded stem or body suitable for application by an ordinary corking machine it is
necessary to make the screw-threaded part of the stem or body of smaller diameter
than that of the cork, ring or cylinder, but in this case the screwed ring or cap as
described and shewn in the Specification of my said former Patent No. 16592
of 1889 is not suitable for withdrawing the stopper from the bottle or jar, as the
said ring when turned would bear upon the cork ring or cylinder and prevent its
withdrawal.
To overcome this difficulty I provide a cap or cylinder having interior and
exterior screw threads, the interior thread being adapted to receive the screw
threaded stem of the stopper and the exterior thread to receive an internally
threaded ring adapted to screw over the said cap or cylinder and to bear upon the
mouth of the bottle.
To withdraw a stopper from a bottle or jar the cap or cylinder with the ring
therein is screwed over the threaded stem of the stopper; by then turning the ring
the latter will be caused to bear upon the mouth of the bottle and will raise the cap
or cylinder with the stopper.
It will be obvious that in some cases the device can be attached to a counter or
other suitable support and be operated by hand or by gearing.

COMPLETE SPECIFICATION..
Improvements applicable to Stoppers for Bottles, Jars, and the like.
I, GERARD COLLINGWOOD CLARK, of 4, Ashland Place, in the County of
London, Manufacturer, 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 that class of stoppers described in the Specification of my
former Letters Patent No. 10762 dated the 3rd of July 1889 and to the means for
withdrawing such stoppers from bottles or jars forming the subject of my former
Letters Patent No. 16592 of the 21st October 1889.
I have found in practice that in order to make my stoppers having a screw-
threaded stem or body suitable for application by an ordinary corking machine it
is necessary to make the screw-threaded part of the stem or body of smaller diameter
than that of the cork ring or cylinder, but in this case the screwed ring or cap as
described and shewn in the Specification of my said former Patent No. 16592
of 1889 is not suitable for withdrawing the stopper from the bottle or jar, as

page_text: the said ring when turned would bear upon the cork ring or cylinder and prevent
its withdrawal.
To overcome this difficulty I provide a cap or cylinder having interior and
exterior screw-threads, the interior thread being adapted to receive the screw-
threaded stem of the stopper and the exterior thread to carry an internally
threaded ring or collar adapted to screw over the said, cap, or cylinder and to bear
upon the mouth of the bottle.
It will be obvious that in some cases the device can be attached to a counter or
other suitable support and be operated by hand or by gearing.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :--
Figure 1 is a sectional view shewing a bottle-neck having my stopper therein
and provided with means for withdrawing the same in accordance with my
invention:
Figure 2 is a view similar to Figure 1 shewing the stopper withdrawn from the
bottle-neck:
Figures 3 and 4 are a plan and vertical section respectively of the withdrawing
device; and
Figure 5 is a view illustrating a modification.
a indicates the bottle-neck, and the stopper provided with a screw c as described
in the Specification of the Patent before referred to, except that the said screw is
of smaller diameter than the cork.
d is the cork-withdrawing-device, e being the cap or cylinder thereof having
interior and exterior screw-threads, and the internally threaded ring or collar, the
exterior threads of the said cap or cylinder being designed to fit the thread in the
ring or collar, and the interior thread of the cap to fit the screw of the cork. g is
a: flange which serves to prevent the cap or cylinder from coming out of the ring or
collar at one end, and is a ring serving the same purpose at the other end of
the collar.
The operation of this withdrawing device is as follows:-that is to say,-The
cap or cylinder being at one end of the ring or collar, as shewn in Figure 4, the
device is applied to the screw of the stopper, as shewn in Figure 1, by turning
the collar and, as the turning is continued, the cap or cylinder is gradually raised
within the collar, as shewn in Figure 2, thereby withdrawing the cork. The
unscrewing of the cork from the withdrawing device causes the return of the cap
or cylinder to its original position, so that the said withdrawing device is again
ready for use when required.
If it is desired to withdraw a cork from a bottle by a direct pull I advantageously
employ the hand-nut shewn in Figure 5 which is simply screwed onto the screw of
the cork.
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.
-
The improvements in and applicable to stoppers for bottles, jars and like vessels
substantially as described and illustrated in the several figures of the accompanying
drawing.
