PROVISIONAL SPECIFICATION.
Improvements in or relating to Bottles and Stoppers for the same.
We, WILLIAM ROBERT MAUD, of The Market Place, Pontefract, in the
County of York, Chemist and Dentist, and WILLIAM WHARLDALL, of Southgate,
Pontefract aforesaid, Joiner, do hereby declare the nature of this invention to be
as follows:
Its
This invention relates to improvements in bottles and stoppers for the same.
object is to provide simple, cheap, self-fitting means capable of being easily applied
(and afterwards readily released) for closing the mouth or orifice of a bottle. The
invention may be used with any kind of bottle such as for instance, for aërated and
fermented liquors, sauces, jams, as well as for chemists' bottles and the like.
According to this invention the bottle is made with an enlarged neck in which is
cut or formed an internal screw groove, and also within the neck at a suitable
distance from the orifice is an internal flange or lip. A recess may also be formed
above the flange when preferred. On the flange and partially within the said
recess is a washer or ring of cork or other suitable material of any desired size.
The stopper is made of any non-porous (or practically so) material, such as lignum-
vitæ, glass, metal, or porcelain, and has a screw thread cut or formed upon a portion
of its periphery so as to fit into the screw groove in the bottle neck. The end of
the stopper below the screw thread may be slightly reduced (to form a shoulder)
and made somewhat after the shape of an acorn or tapered to admit of the end of
the stopper first entering the washer for forcing the latter out laterally, and then
when the shoulder has been screwed down upon the upper surface of the washer to
compress it tightly between the said shoulder and the internal flange, thereby
forming an impervious joint.
Or instead of forming a recess in the bottle neck and cutting or forming a screw
thread on the stopper as above described a suitable recess may be formed in the
plug portion of the stopper. When this is done the herein before mentioned
washer is placed within the bottle neck and the tapered plug portion of the stopper
driven through it thus forcing the washer tightly against the internal flange and
embedding its periphery in the screw groove of the bottle neck (to form a screw
thread for its withdrawal) and its inner portion in the recess in the plug; thereby
fastening the parts together and making an unmoveable stopper except by
unscrewing.
Each of the above described stoppers may be provided with an enlarged head or
with a hole for the insertion of a cross piece to act as a handle.

COMPLETE SPECIFICATION.
Improvements in or relating to Bottles and Stoppers for the same.
We WILLIAM ROBERT MAUD, of The Market Place Pontefract, in the County
of York, Chemist and Dentist, and WILLIAM WHARLDALL of Southgate,
Pontefract aforesaid, Joiner do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to improvements in bottles and stoppers for the same.
Its

page_text: object is to provide simple, cheap, self-fitting means capable of being easily applied
(and afterwards readily released) for closing the mouth or orifice of a bottle. The
invention may be used with any kind of bottle such as for instance for aerated and
fermented liquors, sauces, jams, as well as for chemists bottles and the like.
In the drawings :-
Fig. 1 is a part sectional elevation with a stopper constructed according to this
invention applied.
Fig. 2 a part sectional elevation of bottle showing screw thread and recess in its
neck for receiving the stopper.
Fig. 3 a sectional elevation of bottle neck and stopper.
Figs. 4, 5, 6, 7, 8 and 9, are respectively elevations and plans of portions of the
stopper.
Like parts in all the views are marked with the same letters of reference.
A, is the bottle neck in which is formed an internal screw thread or groove a
a socket a¹ and a flange a² as shown at Figs. 1 and 2. In the socket a' is placed so
as to rest upon the flange a a washer B made of cork or any other suitable material
for the purposes to be hereafter described. C is stopper which may be made in
one (as shown at Fig. 3) or more parts, preferably two, as shown at Fig. 1.-of
any non-porous (or practically so) material such as lignum-vitæ glass, porcelain, or
metal or combinations of them. In the drawings we have shown at Fig. 1 the
stopper made in two portions and of different materials, that is, the lower portion C
or stopper proper which comes in contact with the washer B is preferably made
(though not necessarily so) of glass or other non-porous material whilst the top or
upper portion C₁ may be made of wood such as beech or the like.
The stopper C is provided with a circumferential flange c (slightly smaller in
diameter than the washer B) which may or may be under cut as shown at c* to
form a shoulder, and the upper portion or shank e¹ of the stopper arranged to fit
into a hole e provided for its reception in the top C' as shown at Fig. 1 whilst its
lower end 2 is shaped somewhat like an acorn and made to pass within the hole >>
(slightly smaller in diameter than the orifice of the bottle at a) in the washer B.
The top C is preferably made square or nearly so with the corners slightly
rounded off, to allow for expansion and contraction without injury to glass bottle,
and in order to prevent it splitting it is made plank way of the wood, that is to say
with the grain running across the stopper head instead of vertically and on its sides
is cut a screw thread c to fit the internal screw thread a of the bottle neck.
the under surface of the top C' is formed a recess c³ for the reception of the shank c
of the stopper C, whilst in its upper surface is cut a groove or slit c³ for the
reception of a screw driver like tool for fastening and unfastening the stopper.
When it is preferred to make the stopper in the shape shown at Fig. 3 the end e²
may be formed either of glass porcelain lignum-vitæ or other porous material
attached to a top piece, or the stopper may be made in one piece.
In
The bottle having been filled with the required liquid or other material the
washer B is either then placed in the socket al so as to rest on the flange a² or is
placed on stopper C and all goes into the bottle together. The top C' to which the
stopper C has been previously attached is afterwards inserted in the bottle neck and
screwed down until the end has not only passed a sufficient distance through the
washer for expanding it laterally against the wall or vertical portion of the socket,
but the under surface bas tightly compressed the washer on to the internal
Hange a thereby forming an impervious joint.
When the above stopper is used for acrated and fermented liquors as soon as the
stopper is released provision is made (by forming the top C₁ square as described
and shown) for allowing the gases to escape from the bottle before the stopper is
completely withdrawn.
Or instead of forming a recess in the bottle neck and cutting or forming a screw
thread on the stopper as above described a suitable recess may be formed in the
plug portion of the stopper. When this is done the herein before mentioned washer
is placed within the bottle neck and the tapered plug portion of the stopper driven

page_text: through it thus forcing the washer tightly against the internal flange and embedding
its periphery in the screw groove of the bottle neck (to form a screwthread for its
withdrawal) and its inner portion in the recess in the plug thereby fastening the
parts together and making an immovable stopper except by unscrewing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved bottle stopper consisting essentially of a stopper made in one or
more parts and screwed into the neck of the bottle for compressing and laterally
expanding a washer against a flange and a socket formed for its reception within
the bottle neck as and for the purposes set forth.
2. The combination with a bottle neck or orifice such as A having an internal
screw thread, sockets and flange formed therein, of a stopper such as C formed in
one or more portions) provided with a screw to engage with the screw thread in the
bottle neck a cone such as c2 and a circumferential flange or shoulder for expanding
and compressing a washer within a socket against a flange formed in the bottle neck
as and for the purposes set forth.
3. In the stoppering of bottles and jars the combination of neck A having an
internal screw thread a socket a and flange a² stopper C screwed top Cand
washer B as and for the purposes set forth.
