Improvements in or relating to Bottle Stoppers.
A communication from STERLING GLOVER, of Buffalo, New York, United States of
America, Manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
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:-
This invention relates to that class of bottles which have stoppers that can be
easily placed in position in the neck of the bottle or removed, and which, when in
position, form with an interposed washer a hermetical seal, making the bottle on this
account particularly suitable for holding aerated water, beer, and other liquids, as a
portion of the contents may be drawn off and the rest kept for future use without
injury.
This invention consists in certain improvements in existing forms of bottles, and I
will now proceed to definitely describe the manner in which it is proposed to carry
out this invention.
In the drawings
:
Fig. 1 is an elevation of the improved bottle; Fig. 2 is a central vertical section
of the upper portion of the improved bottle; Fig. 3 is a partial vertical section
taken on the line - of figure 1; Fig. 4 is a top plan view of the neck of the
bottle with the stopper removed; Fig. 5 is a partial vertical section taken on the
line y-y of figure 2 with the stopper in position; and Figs. 6, and 8 are different
views of the stopper.
Referring to the drawings, the stopper a which can be made of glass, metal,
wood or other suitable material, is formed in one solid piece on the principle of a
locking button with the upper finger disc a' the stem or shank a³ projecting
down-
ward from it and carrying at its lower end two lugs or projections a³ a³.
A washer b is fitted into the stem of the stopper against the under face of the
finger disc a'.
The bottle consists of the body portion c and the neck c¹. Upon the inner wall
of the neck and placed oppositely are the inwardly-projecting ledges c² c².
After the stopper is introduced into the neck of the bottle by turning the stopper
one-quarter way round, the lugs a³ a³ of the stopper engage with the ledges c³ in
the neck of the bottle, the pressure of the parts upon the interposed washer which
may be of rubber, cork, leather, or the like, forms a hermetic seal.
The construction just outlined is substantially of an old form and to this is added
the important improvement which makes it at once a perfect bottle for the purposes
herein before mentioned. In the old form outlined in the construction the stopper was
liable to slip and become detached from unavoidable jolting transportation or
handling for if once started the pressure of the gas within the bottle would invariably
complete the detachment.
In order to avoid this serious difficulty and provide a perfect bottle, a central
recess has been formed on the under side of each of the ledges c in the neck of
the bottle so that when the lugs a a² on the stopper are turned a quarter revolution
these slip into these recesses and thus effectually prevent the accidental displacement
of the stopper, which can be easily removed when desired by applying pressure
enough to throw the stopper down against the elastic washer sufficiently to effect an
engagement of the ledges from the recess.
It is obvious that this invention is easily applicable to fruit jars, or other

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is;-
In a bottle the combination with the neck provided with inwardly projecting
ledges upon its inner wall such ledges being centrally recessed upon their under
surfaces of the stopper having a shank and projecting lugs all operating substantially
as shown and described.
