An Improved Cork Stopper for Bottles and other Vessels.
We, WILLIAM FRANOIS ANDERSON of 59 Norfolk Road Dalston in the County of
Middlesex, and HENRY DAVIDSON of 86 Mayfield Road Dalston in the County of
Middlesex, both Engineers do hereby declare the nature of this invention to be as
follows :-
With
We bore a hole in the cork partly down from the top, and we insert a plug of wood,
composition, earthenware, metal, or other suitable material; of a square, circular, or
polygonal section; and surmounted with a head or cap this plug is secured to the
cork with shell-lac or other suitable cement. We now cut a screw on the outside of
the cork, taking care that the top of the cork shall be larger than the bottom.
a cork thus strengthened by the plug and made to fit a bottle having a female screw
formed in the neck or mouth, we make a tight joint without the interposition of a
washer, or any other medium. In some cases, we use a hollow metal plug, square or
polygonal in section, cemented into the cork, the latter having a screw cut on the
outside as before described by means of a key, the shank of which is made to fit the
hollow plug, the cork can be inserted in, and removed from the bottle. For large
corks or "bungs" we use a metallic bush with a female screw; this bush we secure
to the cask, and we insert, and remove the screwed bung, by means of a key made to
fit a hollow metal plug sunk into the bung, as before described. Sometimes we use
in the same bung, two or more hollow plugs, and we make the key with prongs to fit
the same.

We WILLIAM FRANCIS ANDERSON of 43 Norfolk Road Dalston in the County of
Middlesex and HENRY DAVIDSON of 86 Mayfield Road Dalston in the County of
Middlesex both Engineers do hereby declare the nature of this invention and in what
manner the same is to be performed, to he particularly described and ascertained in and
by the following statement :-
We bore a hole in a cork partly down from the top, and we insert a plug of wood
composition earthenware, metal, or other suitable material, of a square, circular or
polygonal section; and surmounted with a head or cap. This plug is secured to the
cork with shell-lac or other suitable cement. We now cut a screw on the outside of
the cork taking care that the top of the cork shall be larger than the bottom. With a
cork thus strengthened by the plug and made to fit a bottle having a female screw
formed in the neck or mouth, we make a tight joint without the interposition of.,a
washer or any other medium. In some cases we use a hollow metal, plug, square or
polygonal in section cemented into the cork, the latter having a screw cut on the
outside as before described. By means of a key, the shank of which is made to fit
the hollow plug, the cork can be inserted and removed from the bottle.

For larger corks or bungs we use a metallic bush with a female screw. This
bush we secure to the cask, and we insert and remove the screwed bung by means of a
key made to fit a hollow metal plug sunk into the bung as before described. Some-
times we use in the same bung two or more hollow plugs, and we make the key with
prongs to fit the same.
We now describe the drawing attached to our specification. Fig. 1 shows a bottle
having a screw formed in the neck and furnished with a cork " a" having a corre-
sponding screw cut on the outside of it and strengthened with the plug "6" a hole is
shown is shown through the cap, to facilitate wireing if necessary.
Fig. 2 shows a similar bottle and screwed cork", a "fitted with a hollow metal
liner square in section as shown at "c."
Fig. 3 shows the key used for inserting and removing the cork.
Fig. 4 is the plan of a bung with a square metal plug sunk in, to be removed by a
key with a square end.
Fig. 5 is a section showing a portion of a stave of a cask "e" with the bush "ƒ”
inserted, and the screwed bung "with the square metal plug "h."
Fig. 6 is the plan of a similar bung with three circular hollow plugs "iii”
which in this case are screwed into the bung.
Fig. 7 is a section through the stave of a cask showing the bush, screwed bung, and
hollow plugs, for the removal of the bung by a three-pronged key.
Fig. 8 shows the screwed cork applied to an ordinary chemical bottle. In this case
the cork is shown sunk into the cap "1" and a separate plug "m" is inserted through
the cap into the cork and fixed with cement.

Fig. 9 is a plan showing the oblong shape of the plug "m."
Similar corks can be used for Jars, Pickle-bottles and the like.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1st. Making a tight joint by means of a cork with a screw cut thereon, with a
screwed bottle or vessel, without the interposition of any washer, or other medium.
2nd. The combination of a plug secured in the body of the cork (to strengthen the
same) with a screw cut on the cork.
3rd. The combination of a hollow plug or liner with a screw cut on the cork fitting
a corresponding screw in the vessel, bottle or cask so that the cork may be removed
by a key.
