AN IMPROVED STOPPER FOR BOTTLES
Year: 1884

page_text: ANDREW MUIR Engineer, of 2 Walbrook London E.C. do hereby declare the
nature of my said invention for "AN IMPROVED STOPPER FOR BOTTLES," to be as
follows, that is to say :-
My Invention of an improved stopper for bottles is for the purpose of avoiding
any projections or impediments inside the necks of bottles which interfere with the
liquid flowing in a perfect free manner in combination with instantaneous action
and great simplicity.
Now according to my invention I make the inside of the neck of the bottle
plain and upon the outside I form a projection or projections with a vertical slot,
The lower part of this projection or projections is or are made inclined.
The stopper is made to drop over, the outside of the neck of the bottle and has
one or more internal projections which agree with the groove or grooves sliding
down the same and standing below the said projection or projections on the
outside of the bottle neck; Now by a slight movement of the stopper in a
circular direction the projection or projections are locked under the incline or
inclines and the top sealed.-Either a ground top or a joint may be used to seal it.

page_text: I ANDREW MUIR Engineer of 2 Walbrook London E.C. do hereby declare the
nature of my said Invention for "AN IMPROVED STOPPER FOR 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 of an improved stopper for bottles is for the purpose of avoiding
any projections or impediments inside the necks of bottles which interfere with
the liquid flowing in a perfect free manner in combination with instantaneous
action and great simplicity.
Now according to my invention I make the inside of the neck of the bottle plain
and upon the outside I form a projection or projections with a vertical slot. The
lower part of this projection or projections is or are made inclined..
The stopper is made to drop over the outside of the neck of the bottle and. has
one or more internal projections which agree with the groove or groves sliding
down the same and standing below the said projections or projection on the
outside of the bottle neck. Now by a slight movement of the stopper in a
circular direction the projection or projections are locked under the incline or
inclines and the top sealed.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings illustrating several
ways in which it may be carried into practice but I do not confine myself to these
particular modes as the details may be greatly varied without departure from the
principle of the invention Referring to the drawings.
Figure 1 is a side elevation of the upper part of a bottle and the stopper
screwed into position.
Figure. 2. is an elevation of the other side of the same.
Figure. 3. is a plan of the neck of the bottle with the stopper removed therefrom.
The stopper in this illustration is thus composed of the top A and sides a¹
and a² with the internal hook pieces a³ and at which are allowed to pass down
the grooves or recesses B and B in the neck of the bottle. It will be noticed that
a slight turn will bring these projections under the shoulders of C and C¹ drawing
the underpart of A upon the upper part of the neck of the bottle to a tight joint.
There may be one, two, or more of the grooves B or B' and projections a¹ a³ on
the stopper to correspond but two will probably be found to generally answer.
The illustrations Figs 4 & 5 shows a modification of my invention with-
out departing from the principle It will be noticed that there are several
threads d, d', d' on each side under which the internal projections or threads of the
stoppers pass. Figure 6 is an inverted plan of the stopper E 1 and Figure 7 is a
plan of the top of the neck of the bottle for the same stopper.
These stoppers & bottles may be made either with ground surfaces or with a
joint intervening such for instance as a recess with a ring of soft material. Neither
do I confine myself to any myself particular material as wood glass vulcanite and
other suitable material may be used.

page_text: Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
The improved bottle stopper having internal provisions a³ and a for taking
under corresponding external provisions outside the neck of the bottle or modifi-
cations of the same principle such for instance as that shewn by Figures 4. 5. 6
and 7 and substantially as herein set forth.
