page_text: LETTERS PATENT to John Bussey of Blackman Street Borough in the County
of Surrey Cork Merchant for an invention of "IMPROVEMENTS IN STOPPERS
PROVISIONAL SPECIFICATION left by the said John Bussey at the Office of
the Commissioners of Patents on the 2nd May 1882.
JOHN BUSSEY of Blackman Street Borough in the County of Surrey Cork
Merchant "IMPROVEMENTS IN STOPPERS FOR BOTTLES JARS AND SIMILAR
RECEPTACLES
"
This Invention relates to an improved stopper for closing the mouths of bottles
jars and similar receptacles and consists in the use of a removeable plug or stopper
of glass porcelain wood or any other suitable material having one or more external
screw threads of any suitable pitch and section formed thereon in combination with
a lining of cork or other suitable elastic or yielding material into which the said
screw threaded stopper is screwed the said lining being inserted into and held in
any secure manner inside the neck of the bottle or vessel to be stoppered which
may be formed if desired as is well understood with a recess to receive such lining.
In order to hold the lining securely in its place when applied to aërated or gaseous
liquids a metal or other ring or collar may be placed over it and held securely
thereon by two or more metal strips passing down the outside of the neck and
bound round with wire or string below the projecting ring or shoulder usually
formed round the necks of bottles the lower ends of the said strips being either of
hooked form or made with a slight shoulder or projection to keep the binding wire
or string in position. It is obvious that various other means may be employed for
securing the said lining inside the neck of the bottle and for example by an internal
flange formed round the neck of the bottle itself but the above has been found to
answer well in practice.

by the said John Bussey in the Great Seal Patent Office on the 2nd November
1882.
JOHN BUSSEY of Blackman Street, Borough in the County of Surrey, Cork
Merchant "IMPROVEMENTS IN STOPPERS FOR BOTTLES JARS AND SIMILAR
RECEPTACLES."
My said invention relates to an improved stopper for closing the mouths of
bottles jars and similar receptacles and consists in the use of a removeable plug or
stopper of glass porcelain wood or any other suitable material having one or more
external screw threads of any suitable pitch and section formed thereon in com-
bination with a lining of cork or other suitable elastic or yielding material into
which the said screw threaded stopper is screwed the said lining being inserted
into and held in any secure manner inside the neck of the bottle or vessel to be
stoppered which may be formed if desired as is well understood with a recess to
receive such lining. In order to hold the lining securely in its place when applied
to aerated or gaseous liquids a metal or other ring or collar may be placed over it
and held securely thereon by two or more metal strips passing down the outside of
the neck and bound round with wire or string below the projecting ring or shoulder
usually formed round the necks of bottles the lower ends of the said strips being
either of hooked form or made with a slight shoulder or projection to keep the
binding wire or string in position. It is obvious that various other means may be
employed for securing the said lining inside the neck of the bottle as for example
an internal flange formed round the neck of the bottle itself.
And in order that my said invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer
to the several figures on the explanatory sheet of drawings hereunto annexed
the same letters of reference indicating corresponding parts in all the figures.
Figure 1 of my drawings is a full sized elevation of the screw threaded stopper
detached. Figure 2 is a vertical section of the upper part of the neck of a bottle
showing the cork lining which receives the screwed stopper in its place inside the
bottle neck. Figures 3 and 4 represent respectively in elevation and plan detached
a metal ring and clip for holding down the cork lining in its place. Figures 5, 6
and 7 show other modes of holding the said lining in position.
a is the stopper of any suitable material having a screw threaded shank b. This
stopper may be moulded from suitable plastic material such as clay or semi-molten
glass or from "dust" as is well understood by the aid of suitable matrices and dies
and powerful pressure. c is the lining of cork or other suitable material which is
to be held securely inside the neck d of the bottle and into which the screwed
stopper is inserted by a rotary motion the screw thread on the stopper forming
its own counter thread in the cork lining by the act of screwing the stopper
therein.
I do not confine or restrict myself to any particular mode of securing the cork
lining inside the neck of the bottle but have given examples at Figures 2, 5, 6
and 7 of certain modes by which this may be accomplished preferring the
arrangements shown at Figures 5 and 6 as answering well in practice.
In figure 2 an internal annular shoulder or projection e is moulded inside the
bottle neck upon which the inner end of the lining c rests so as to prevent it from
being pushed inside the bottle itself whilst it is prevented from being pushed
outwards by the metal washer f projecting over the top of the lining and provided
with lateral strips g (see figures 3 and 4) which pass down the outside of the neck

page_text: and are secured by a wire or string under the usual enlargement on the neck, a
hook or projection h on each strip serving to keep the wire or string in position.
In figure 5 I have shown the cork lining which constitutes the female screw to
the male screw of the stopper as being held in an annular recess i formed inside
the bottle neck but I make no separate claim to such annular recess.
In figure 6 the lining is maintained between an upper internal flange k and two
or more stops or studs moulded inside the neck and in figure 7 I have shown
the said lining as being held in position by two or more conical studs or projections m
moulded inside the neck and entering more or less into the material of the lining
as shown when the said lining is pressed against them by the expansion produced
on inserting the screwed stopper a therein. If found desirable a washer of leather
or other suitable material may be fitted under the head of the stopper as shown
at n in figures 1 and 2.
Having now described and particularly ascertained the nature of my said
invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the invention secured to me by the hereinbefore in part
recited letters patent is :-
The improved stopper consisting of the combination of an externally screwed
plug or stopper with a lining of cork or other suitable yielding or elastic material
secured inside the neck of the bottle or other vessel to be stoppered and constituting
a female screw to the externally screwed plug or stopper substantially as and for
the purpose specified.
In witness whereof I the said John Bussey have hereunto set my hand and
seal this first day of November in the year of our Lord one thousand
eight hundred and eighty two.
JOHN BUSSEY. (L.S.)
