MENTS IN THE MEANS AND APPLIANCES FOR STOPPERING BOTTLES, JARS, AND OTHER
RECEPTACLES."
This Invention relates to improvements in means and appliances for stoppering
bottles, jars, and other receptacles for liquids, fluids, and the like; or any substances
wherein an elastic medium (such as india-rubber) is employed to tighten the
stopper in or on the bottle and thus make an air-tight joint.
This Invention can be carried into effect in stoppering bottles which are-and
which are not-subjected to internal pressure by their contents.
This Invention can be carried into effect by constructing a stoppering apparatus
of the following description, and by forming the neck of the bottle to suit it:-The
stopper consists of a tee headed bolt, pinned or otherwise secured to a head, on the
stem of the said bolt, next to the head, being an irregularly shaped collar of
varying thickness, and above this an india-rubber washer, or a washer of any
suitable substance which has the expanding and contracting properties of india-
rubber, and above it a plain washer. The inside of the bottle neck is formed with
a projection upon which the collar of varying thickness will rest, and it is also so
formed that the irregularly shaped collar will not turn round therein. The inside
of the bottle neck is also made taper, the smaller diameter being uppermost, or the
inside of the bottle neck will have an internal flange or groove at or near its mouth
or it will be otherwise so formed as to retain the improved stopper in the bottle and
form a bearing against which the india-rubber washer will press when the stopper is
tightened in the bottle neck.
Another method of carrying into effect my Invention consists in the construction
of stoppering apparatus of the following description :-A bolt is employed which
has a head and screwed stem or shank; upon the stem is placed a washer of india-
rubber and above this a flanged collar which will rest on the mouth of the bottle;
upon the upper portion of the screwed stem and above the collar is a nut which acts

rubber washer and enlarge it in diameter so as to cause it to press tightly against
the interior of the bottle neck and under the internal flange at or near the mouth
of the bottle neck.
Another method of carrying into effect my Invention consists in the construction of
stoppering apparatus of the following description:
A screwed bolt is employed which has a head; upon this bolt is an internally
screwed collar of irregular shape and an india-rubber washer. The interior of the
bottle neck is so formed as to prevent the irregularly shaped collar from turning
round therein. In using this stopper the bolt would simply be screwed through
the irregularly shaped collar, by which the india-rubber washer would he
expanded and enlarged in diameter and thus forced against the interior of the bottle
neck.
Another method of carrying into effect my Invention consists in the construction
of stoppering apparatus of the following description:-A plain bolt is employed
having a projection at its lower end, the plain stem projecting above the mouth of
the bottle; on the stem of the bolt, immediately above the projection, is an india-
rubber washer and above this a flanged collar, the underside of the flange thereof
resting on the exterior of the mouth of the bottle neck; at or through the extremity
of the stem of the bolt (above the flanged collar) is a horizontal pin or projection to
which is connected an eccentric lever or cam with a handle or ring. In using this
stoppering apparatus the eccentric lever or cam will act on the collar and head of
the bolt, so as to bring them closer together and thus compress the india-rubber
washer and by enlarging its diameter will force it against the interior of the neck
of the bottle.
Another method of carrying into effect my Invention (applicable to bottles
which have external projections at the mouths thereof) consists in the construction
of a stoppering apparatus of the following description:-A cap will be employed
which will be inverted over the mouth of the bottle and under the flange of the cap;
outside the neck of the bottle is an india-rubber washer which will be pressed under
the flange or projection on the exterior of the bottle by a ring with a bridle ex-
tending over the inverted cap; the bridle will be fitted with a set screw or lever
which acting on the inverted cap compresses the india-rubber washer which is
between it and the ring with a bridle.
