COMPLETE SPECIFICATION.
Improvements in Bottle Stoppering.
We, WILLIAM FLETCHER of Smithy Houses, Denby in the County of Derby,
Hotel-keeper, and HENRY DAVIS of Smithy Houses, Denby, aforesaid, Engineer,
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:-
The object of our invention is to provide a ready and effective means of
stoppering bottles in which the stopper may be re-used a great number of times
without being injured, and in which the bottle may be readily and easily stoppered
and opened.
In order that our said invention may be the more readily understood we have
caused to be annexed to this Specification a sheet of drawings, the different figures
and letters of reference marked upon which will be hereafter referred to.
Figures 1, 2 and 3 illustrate one application of our invention and Figures 4, 5
and 6, another application thereof.
Figures 1 and 4 are sections on line a. a. and b. b. respectively.
Figures 2 and 5 are sections through the different forms of stopper and Figures 3
and 6 are plans of the two bottles looking down. The lower portions of the
bottles not being necessary to the illustration of our invention are not shewn,
it will also be noted that in Figures 1, 3, 4 and 6 the stoppers are not shewn in the
bottles.
In carrying our said invention into effect we form the stopper with a collar such
as A having one or more, but preferably two projections or nibs B thereon adapted
to fit easily into vertical slots or recesses C in the inside of the top of the neck D
of the bottles E, a groove F is carried partly round from each of the vertical slots
or recesses sufficient substance of material being left at G for strength; we will
now confine ourselves to the form of stoppering illustrated on Figures 1, 2 and 3, a
seating H is formed on the inside of the neck of the bottle and a rubber or other
suitable elastic packing ring I is placed under, or fitted into a groove under, the
collar A of the stopper. To stopper the bottle the stopper is placed in the neck
of the bottle the two nibs or projections B fitting into the vertical slots or recesses C
and upon turning the stopper the nibs or projections pass along the grooves F which
have a slight lead downwards from the slots or recesses C, until the rubber or other
packing ring is firmly pressed down to the seating H; for unstoppering the
bottle the operation is reversed.
We may if desired employ a spring in the head of the stopper to press the collar
and packing ring down to the seating H. in which case the knob of the stopper
would form a separate piece from the collar and spigot.
In the other adaptation of our invention illustrated on Figures 4, 5 and 6 an
annular groove J is formed in the inside of the bottle neck in which the rubber or
other packing ring K is placed, in stoppering the operation already described is
repeated the difference between the two being that in the first the rubber or other
packing ring to make the joint perfectly tight is on the stopper and the latter it is
in the inside of the bottle neck.
We may construct our bottle or stopper of any suitable material and may in
some cases dispense with the india-rubber or other packing ring and may if desired
provide a suitable means of securing the stopper to the bottle to prevent the
former getting lost.
It is also evident that we may vary the details of our invention such as altering
the shape of the stopper or bottle: but

page_text: 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 :-
The improved means of stoppering bottles consisting of a stopper with collar and
one or more nibs or projections thereon adapted to fit into the recesses C and pass
along the grooves F when the stopper is turned, in combination with a rubber or
other packing ring either on the said stopper as at I and adapted to fit down to a
seating in the inside of a bottle neck such as H, or fitted into an annular groove
such as J, substantially as and for the purposes herein described and as illustrated
on the accompanying sheet of drawings.
