Improvements in Bottle Stoppers.
I, FRANK HILLS MOYER, Real Estate Agent, of 16, East Eagle Street, in the City
of Buffalo, in the County of Erie, and State of New York, United States of America,
lo hereby declare the nature of my invention for "IMPROVEMENTS IN BOTTLE
STOPPERS," 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 hottles 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 hermetic seal making the bottle on this account
particularly suitable for holding aerated waters, beer and other liquids, as a portion of
the contents may be drawn off and the rest kept for future use without injury.
My invention consists of certain improvements in existing forms of bottles, and I
will now proceed to definitely describe the manner in which I propose to carry out my
invention.
In the drawings,
Figure 1 is an elevation of my improved bottle.
Figure 2 is a central vertical section of the upper portion of my improved
bottle.
Figure 3 is a partial vertical section taken on the lineæ, æ, of figure 1.
Figure 4 is a top plan view of the neck of the bottle with the stopper removed.
Figure 5 is a partial vertical section taken on the line y, y, of figure 2, with the
stopper in position, and,
Figures 6, 7, and 8 are different views of the stopper.
Referring to the drawings:
The stopper, 1, 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
disk, 2; the stem or shank projecting downwardly from it and carrying at its lower
end two lugs or projections, 4, 4.
A washer, 5, is fitted into the stem of the stopper against tho-under face of the
finger disk, 2. The bottle consists of the hody portion, 6, and the neck, 7. Upon
the inner wall of the neck, and placed oppositely, are the inwardly-projecting
ledges, 8, 8. After the stopper is introduced into the neck of the bottle by turning
the stopper one quarter way round the lugs, 4, 4, of the stopper engage with the
ledges, 8, 8, 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, forming, as hereinafter
described, a hermetic seal.
In the form thus far described owing to the construction the stopper is liable to
slip and become detached from unavoidable jolting in transportation or handling, for
if once started the pressure of the gas within the bottle would invariably complete the
detachment.
For this reason I have formed a central recess or indenture, 9, on the under side of
each of the ledges, 8, in the neck of the bottle so that when the lugs, 4, 4, on the
stopper are turned a quarter revolution they 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 disengagement of the lugs from the
recesses.
10 is an annular shoulder around the top of the neck of the bottle upon and over
which the elastic washer. 5, extends when the stopper is in position; a circumferential
groove, 11, being formed in the under face of said washer within which said annular
shoulder, 10, fits, or is received; the edge or rim, 12, of said washer depending, as
shown, over the outer circumference of said shoulder.

page_text: Where my, shoulder, 10, and a washer, 5, adapted to engage therewith as herein
explained are not employed it has sometimes been found that upon the stopper being
turned to locking position, its lower portion will spring, up to a certain degree within
the recess, 9, in the bottle neck which act causes the stopper head to rise a sufficient
distance above the top of the bottle neck to admit of the scape of a portion of the gas
within the bottle the sealing of the bottle not being effective where the shoulder. 10.
and washer, 5, herein shown and described are absent. "But by providing the rim of
the bottle neck with an upwardly-extending shoulder, 10, and forming the elastic
washer, 5, with a depending circumferential, flange or, rim which, when the stopper is
in position, will depend over and grip the outer circumference of said shoulder as
shown, a perfect sealing of the bottle is secured for the reason that even, though the
stopper in its locking movement should spring up so as to raise the horizontal portion
of the washer slightly above the rim of the bottle neck the flange, 12, on said
washer will still cover the space intervening between said rim and washer and,
gripping the outer circumference of said. shoulder, hermetically close the bottle neck
opening.
It is obvious that my invention is equally applicable to fruit-jars and other
vessels.

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:
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,
and a circumferential shoulder extending upwardly from the rim of the bottle neck,
of a stopper having a shank and projecting lugs to engage the recessed ledges, and an
elastic washer to engage the shoulder on the rim, substantially as and for the purposes
set forth.
