I, FREDERICK TROTMAN of Pall Mall, London S.W. Refreshment Contractor do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in bottle-stoppers.
In carrying my invention into practice I proceed as follows that is to say :-I employ
as a central core or stein to the said stopper a piece of wood, vulcanite, glass, earthen-
ware or other suitable material. This central core or stem is provided with a head or
cap that extends over the neck of the bottle when the stopper is inserted therein such
cap being preferably serrated, roughened or corrugated on its periphery to enable a
person to obtain a firm hold of the same. In some cases morcover the said cap is
provided with one or more grooves in it to receive wire or string when such is used to
hold the said stopper in place. Directly below such cap and forming part of the afore-
said stem is an annular shoulder or enlargement of such stem. Upon this shoulder I
fit a ring of india-rubber or other flexible material which when the stopper is inserted
in the bottle-neck is designed to make a perfect joint between the lip of the stopper
and the bottle. Below this shoulder is the stem proper covered with an annular plug
or ring of cork or other substance which is not deleterious to the contents of the
bottle and which makes the stopper fit tight within the bottle whilst at the same
time it prevents the liquor therein coming in contact with the ring of india-rubber
or other flexible material above referred to. In order to secure such cork ring
or plug firmly upon the stein or core I coat such stem with gum, shellac or other
suitable adhesive material before placing the ring thereon. Or instead of this I
in some cases form such stem with a roughened, corrugated, grooved or screwed
exterior so that the cork when forced thereon will rigidly adhere thereto. I prefer to
form the stem and enlargement thereon tapering inwards so that the flexible ring and
cork plug or ferrule may be more readily pushed into the bottle-neck to hermetically
seal the same.

page_text: 1, FREDERICK TROTMAN of Pall Mall London, S.W. Refreshment Contractor 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 improvements in bottle-stoppers.
In the accompanying drawing I have illustrated two forms of stoppers constructed
in accordance with my invention.
Figure 1 is an exterior view and Figure 2 a plan of one of the said stoppers
and
Figure 3 is a central section of the same.
Figure 4 is a central section shewing a modification of the arrangements shewn in
Figures 1 to 3.
Like letters indicate the same parts in the several Figures.
In carrying my invention into practice I proceed as follows that is to say :-I employ
as a central core or stem to the said stopper a piece a of wood, vulcanite, glass,
earthenware or other suitable material. This central core or stem is provided with a
head or cap 6 that extends over the neck of the bottle when the stopper is inserted
therein such cap being preferably serrated roughened or corrugated on its periphery
to enable a person to obtain a firm hold of the same. In some cases moreover
the said cap is provided with one or more grooves as at c to receive wire or string
when such is used to hold the said stopper in place. Directly below the cap
and forming part of the stem a is an annular shoulder or enlargement d. Upon this
shoulder I fit a ring e of india-rubber or other flexible material which when the stopper
is inserted in the bottle-neck is designed to make a perfect joint between the lip of the
stopper and the bottle. Below this shoulder d is the stem f covered with an annular
plug or ring g of cork or other substance which is not deleterious to the contents of
the bottle and which makes the stopper fit tight within the said bottle whilst at the
same time it prevents the liquor therein coming in contact with the ring e. In order
to secure the cork ring or plug 9 firmly upon the stem or core fI in some cases coat
such stem with gum, shellac or other suitable adhesive material before placing the
ring g thereon. Or instead of this I in some cases form such stem with a roughened,
corrugated, grooved or screwed exterior so that the cork when forced thereon will
rigidly adhere thereto and be prevented from turning. For instance in Figures 1
and 2 I have shewn the stem provided with a series of projections which hold the
cork g in position and prevent its turning upon the said stem. In Figure 4 I have
shewn the stem as screw-threaded to retain the cork g in position.
I prefer to form the stem and enlargement d thereon tapering so that the flexible
ringe and cork plug or ferrule g may be more readily pushed into the bottle-neck to
hermetically seal the same.

page_text: My improved stoppers can be used in ordinary bottles even if the mouths are
chipped.
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 :-
A bottle-stopper consisting of a core having the shoulder d and stem ƒ upon which
are fitted the ring e and plug 9 substantially as set forth and for the purposes
specified.
