IMPROVEMENTS IN THE NECKS AND STOPPERS OF BOTTLES
Year: 1884

page_text: I, ROWLAND BATEMAN of No 1 Lower Essex Street Birmingham in the County.
of Warwick Billiard Table Maker do hereby declare the nature of my invention
for "IMPROVEMENTS IN THE NECKS AND STOPPERS OF BOTTLES " to be as follows,
that is to say :-
My Invention has for its object improvements in the. necks and stoppers of
bottles so as to render them more simple in action and secure besides allowing the
stoppers to be used an indefinite number of times.
My stoppers aro made from either glass, metal, wood or other suitable material.
with a parallel or nearly parallel piece to enter the neck of the bottle and an
enlarged head piece with a flat ground or level shoulder which would rest upon the
ground or level top of the neck of the bottle. At or near the bottom of the
parallel piece of the stopper which enters the neck of the bottle are two projecting
pieces one on each side. The neck of the bottle internally is formed with two
nearly semi-circular projections leaving on each sido a groove widened out at the
top and with rounded corners at the bottom. The bottom of these projections are
inclined and the locking action of the stopper is as follows:-
The two projections on the stopper slide down the two grooves in the neck of
the bottle until the shoulder of the stopper rests upon the top of the neck when a
slight turn of the stopper brings the projections against the inclined projecting
surfaces in the neck of the bottle which draws the stopper tightly down. An
india rubber or other ring may be introduced if desired between the stopper and
the top of the bottle to assist in forming a tight joint.

I, ROWLAND BATEMAN of N° 1 Lower Essex Street, Birmingham in the County
of Warwick, Billiard Table maker do hereby declare the nature of my invention
for "IMPROVEMENTS IN THE NECKS AND STOPPERS OF BOTTLES and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement to be as follows that is to say :-
My Invention has for its object improvements in the necks and stoppers-of-
bottles so as to render them more simple in action and secure besides allowing the
stoppers to be used an indefinite number of times.
My stoppers are made from either glass metal, wood or other suitable material
with a parallel or nearly parallel piece to enter the neck of the bottle and an
enlarged head piece with a flat ground or level shoulder which would rest upon the
ground or level top of the neck of the bottle. At or near the bottom of the
parallel piece of the stopper which enters the neck of the bottle are two projecting
pieces one on each side. The neck of the bottle internally is formed with two
nearly semi circular projections leaving on each side a groove widened out at the
top and with rounded corners at the bottom. The bottom of these projections are
inclined and the locking action of the stopper is as follows:-
The two projections on the stopper slide down the two grooves in the neck of
the bottle until the shoulder of the stopper rests upon the top of the neck when a
slight turn of the stopper brings the projections against the inclined projecting
surfaces in the neck of the bottle which draws the stopper tightly down. An
india rubber or other ring may be introduced if desired between the stopper and
the top of the bottle to assist in forming a tight joint.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings giving four views of my
invention applied to a bottle:
Figure 1 is a plan looking down upon the mouth of the bottle.
Figure. 2. is an inverted plan of the stopper which may be made from any
desired material.
Figure. 3. is a part sectional elevation on line C. D. showing the stopper locked
in position.
Figure. 4. is a part sectional elevation on line A. B. also showing the stopper
locked in position.
The stopper E is formed with the plug e¹ and the projections e³ and eª.
The inside of the neck of the bottle has also two projecting parts h and h¹ which
extend sufficiently far to leave the spaces and . The projections e¹ and e³ of
the stopper slide down the recesses & and k¹ of the neck of the bottle when the
stopper is turned round these projections ** and e³ are brought under the shoulders
formed by h and h¹.
When a soft rubber or other washer N is used little if any taper is required
under the shoulders h and h¹ Lut in the case of a ground surface joint more taper
would be required. The projections or shoulders ŉ may be made either shallower

page_text: or deeper according to the strength of bottle and the design and material of the
stopper.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The improvements in the necks and stoppers of bottles consisting of an internal
projection or projections upon the neck and an external shoulder or shoulders upon
the stopper for locking the same in position substantially as herein set forth.
