Bottle Stopper.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Karl Kiefer of Cincinnati, Ohio, United States of America,
Mechanic, to be as follows :-
This invention relates to the class of bottle stoppers which have their fastenings
on a rim of the bottle neck. No special form of bottle neck is necessary for this
device, nor is it necessary that the device should be permanently fastened to the
bottle.
The stopper can be used for any ordinary bottle, but it is specially adapted to
glass bottles charged with liquids of higher than atmospheric pressure, where the
common cork is apt to leak.
The stopper consists of the following parts -A cap which encloses a gasket,
and two frames each having a swallow-tailed piece hinged or pivotted thereto.
Each fraine is composed of two bars one end of which is riveted to the cylindrical
part of the cap and the other ends are connected to the swallow tailed piece by
long rivets forming hinges. Each pair of bars is fastened to one side of the
swallow tailed piece and is connected in the manner described, to the cap, so as to
act as levers on diametrically opposite sides of the bottle neck.
The stopper is put on in the following manner :-The cap is brought into the
right position and the two sides are put below the rim of the bottle neck.
Pressure is then exerted on the hinges causing the frames and swallow tailed
pieces to fold up inwards until the hinges come in contact with the bottle neck. In
this position they will remain by themselves.
The gasket can be manufactured either out of cork, wood, or rubber, or both
combined, according to the pressure in the bottle.
The swallow-tailed pieces are bent according to the form of the bottle neck.
In a modified form of the invention the cap has an aperture on its top, and a set
screw passing therethrough. On the projection of this screw a plate is loosely
riveted. The gasket is placed against this plate which can be lowered and raised
by means of the set screw to suit the height of the bottle neck.

COMPLETE SPECIFICATION.
Bottle Stopper.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of
London, Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, as communicated to me by Karl Kiefer,
of Cincinnati, Ohio, United States of America, to be particularly described and
ascertained in and by the following statement :-
This invention relates to the class of bottle stoppers which have their fastenings
on a rim of the bottle neck. No special form of bottle neck is necessary for the
Price 77

page_text: device which forms the subject of this invention, nor is it necessary that the device
should be permanently fastened to the bottle.
The stopper can be used for any ordinary bottle, but it is specially adapted to
glass bottles charged with liquids of higher than atmospheric pressure, where the
common cork is apt to leak.
In the drawing the device is shown in different positions. There is also one
construction shown adapted to be fitted to bottle necks of different sizes.
Fig. 1 shows the stopper pat on the bottle and ready to be closed;
Fig. 2 shows the stopper in closed condition;
Fig. 3 is a view from the top on the closed stopper;
Fig. 4 shows the diagram of the opened and closed stopper; and
Fig. 5 shows an adjustable bottle stopper, which can be fitted to most bottles
with rims.
Similar letters refer to similar parts throughout the several views.
The stopper consists of the following parts; (Figs. 1-3). A cap a, which
encloses a gasket b, and two frames c, each having a swallow-tailed piece d, hinged
or pivotted thereto.
Each frame C, is composed of two bars one end of each being riveted to the
cylindrical part of the cap a., and the other ends are connected to the swallow-tailed
pieces d by long rivets e, forming hinges. Each pair of bars c., is fastened to
one of the swallow-tailed pieces d. d., and is connected in the manner described
to the cap a, so
as to act as levers on diametrically opposite sides of the
bottle neck.
The stopper is put on in the following manner :-The cap a, is brought into the
right position, and the two swallow-tailed pieces d are put below the rim of the
bottle neck as shown in Fig. 1 in view and Fig. 4 in diagram.
Pressure is exerted on the hinges f, and f1, causing the knee levers composed of
the frames o., and the swallow-tailed pieces d to fold up until the parts cover each
other, at which moment the greatest pressure is exercised on the under side of the
tim on the bottle neck. In order to ensure the device remaining in the closed
position, it is necessary to let the levers go over the dead point until the
hinges,, come in contact with the bottle neck. In this position they remain by
themselves.
The gasket b, can be manufactured. either out of cork, wood or rubber, or both
combined, according to the pressure in the bottle.
The swallow-tailed pieces d, are bent according to the shape of the bottle neck
as shewn in Figs. 1 and 2.
in Fig. 5 the cap has an aperture on its top, and a set screw g. passing there-
through. On the projection i of this screw, a plate k is loosely riveted.
The gasket b, is placed against this plate k, which can be lowered and raised by
means of this set screw y, to shit the height of the bottle neck.
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:
1. In a bottle stopper the combination of a cap with two sets of levers pivotally
connected thereto, acting on opposite sides of the bottle neck substantially as
described.
2. A bottle stopper comprising a cap, two pairs of bars pivotally connected
thereto, and two side parts hinged to said bars substantially as and for the purpose
herein described.
3. The bottle stopper comprising a cap with two pairs of bars pivotally connected
thereon at diametrically opposite points and side parts pivotally connected to said
bars substantially as and for the purpose herein described.
4. The bottle stopper comprising a cap with two equal lever combinations, each
of which comprises a pair of bars, and one side part hinged to each other
substantially as and for the purpose herein described.

page_text: 5. The bottle stopper comprising the cap, with two distinct sets of lever com-
binations symmetrically arranged in regard to a vertical plane passing through a
diameter of the cap and the longitudinal axis of the attached bottle substantially as
described and for the purpose stated.
6. The bottle stopper comprising a cap part, two sets of levers, and means of
adjusting the combination to bottle necks of different heights substantially as
described with reference to Fig. 5 of the accompanying drawings.
