IMPROVEMENTS IN BOTTLES AND STOPPERS FOR THE SAME
Year: 1884

page_text: We, FREDERICK AUGUSTUS BID, of 100, Moor Street, Birmingham, in the .
County of Warwick, Ale and Porter Merchant, and JOSEPH BEVERLEY FENBY, of
Sutton Coldfield, in the said County, Civil Engineer do hereby declare the nature
of our invention for IMPROVEMENTS IN BOTTLES AND STOPPERS FOR THE SAME
to be as follows:-
Our present invention consists of improvements in a former invention which we
described in our provisional specification of the 18th of March, 1884, No. 5043.
The chief object of our present invention is to provide an improved construction
of stopper for use with bottles having screw threads or inclines within the necks of
the said bottles, such screw threads or inclines not being continuous for the whole
circumference, but each screw thread or incline having a separate start or lead.
We use two or more screw threads or inclines, and for convenience of description
we shall describe a bottle, and a stopper for the same, where we use two screw
threads or inclines in the neck of the bottle; though, for bottles having necks of
large diameter, we prefer to use more than two of the said screw threads or
inclines. The two screw threads or inclines within the neck of the bottle are parts
of a double threaded screw.
Each thread or incline is solid on the inside of the neck of the bottle, that is, we
use raised threads, not grooves.
Our improved stopper is constructed in the following manner.
The form of the stopper is that of a short bolt with a flanged head. The stem
of this bolt is small enough to pass freely into the neck of the bottle where the
screw threads or inclines lessen the bore of the said neck. In the said stem of the
stopper is a hole passing through it in the direction of its diameter, and level with
the under side of this hole through the stem are small lips or brackets formed on
the circumference of the stem close to the ends of the hole passing through the
stem, the upper surfaces of such lips or brackets being thus continuations of the
bottom surface of the hole. A plug or key of wood, vulcanite, horn or other
suitable material is driven through the hole in the stem of the stopper. This is of
such a length that its ends project beyond the circumference of the stem of the
stopper sufficiently to form studs to engage with the screw threads or inclines in

page_text: the neck of the bottle; and the lips or brackets formed on the stem of the stopper
act as supports to strengthen these projecting ends of the plug or key against the
strain caused by tightening the stopper in the neck of the bottle. The stopper is
made of glass, earthenware, cement or other hard material.
An airtight joint is secured by causing the stopper to tighten on to a ring or disc
of elastic material, such as rubber or cork.
Sometimes we form the lips or brackets spoken of so as to support the projecting
ends of the plug or key on both sides as well as underneath.
It will be readily understood that the stopper drops vertically into its place in
the neck of the bottle and is tightened by a turn through part of a revolution.
Doted this 98th day of October 1884.

page_text: We, FREDERICK AUGUSTUS BIRD, of 100, Moor Street, Birmingham, in the
County of Warwick, Ale and Porter Merchant, and JOSEPH BEVERLEY FENBY, of
Sutton Coldfield, in the said county, Civil Engineer, do hereby declare the nature
of our invention for IMPROVEMENTS IN STOPPERING BOTTLES and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:—
Our present invention consists of improvements in a former invention which we
described in the specification No. 5043, A.D. 1884.
The chief object of our present invention is to provide an improved construction
of stopper for use with bottles having screw threads or inclines within the necks
of the said bottles, such screw threads or inclines not being continuous for the
whole circumference, but each screw thread or incline having a separate start
or lead
Our improved stopper is constructed in the following manner. The form of the
stopper is that of a short bolt with a flanged head. The stem of this bolt is small
enough to pass freely into the neck of the bottle where the screw threads or
inclines lessen the bore of the said neck. In the said stem of the stopper is a hole,
passing through it in the direction of its diameter; and level with the under side
of this hole through the stem are small lips or brackets formed on the circumference
of the stem close to the ends of the hole passing through the stem, the upper
surfaces of such lips or brackets being thus continuations of the bottom surface of
the hole.
A plug of wood, vulcanite, horn, or other suitable material is driven through the
hole in the stem of the stopper, and this plug extends at each end to a sufficient
extent to engage with the screw threads or inclines in the bottle neck.
The lips or brackets formed on the stem of the stopper act as supports to
strengthen the projecting ends of the plug against the strain caused by tightening
the stopper in the neck of the bottle. The stopper is made of glass, earthenware,
cement, or other hard material.
The lips or brackets may be so formed as to support the projecting ends of the
plug on both sides as well as underneath.
In Figs. I and II of the drawings our improved stopper is shewn in elevation.
a a is the plug of wood, vulcanite, horn, or other suitable material, passing
through a hole in the stem of the stopper, and bb are the lips or brackets
supporting the projecting ends of the plug.
The stopper drops vertically into the neck of our improved bottle and is tightened
by a slight turn,

page_text: Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The special construction of stopper described and illustrated.
2. The use in combination therewith of our improved form of bottle having in
the neck screw threads or inclines not continuous for the whole circumference,
