JOHN, JACKSON, the younger. Engineer. 51. Lorn Road, Brixton. London. Av
IMPROVED STOPPER FOR BOTTLES AND JARS.
My invention relates to a simply constructed stopper for bottles and jars.
The objects of my invention, are the production of simple air tight stoppers that
can be fixed on the bottle or jar by pressing on, and removed, by pressing a
projecting piece at the side of the stopper.
I construct the stopper in the following manner, To the upper end of a piece of
metallic tube (by preference brass), I secure a suitable top, thus forming a cap; in
the internal upper part of this cap, I place a plug of suitable material (by
preference deft or china); the lower end of this plug I form conical, over which I
stretch a peice of flexible rubber tube, that is held on by the formation of a shoulder
at the lower end of the plug. Round the upper part of the conical plug, I form a
shoulder, the edges of which, give the plug a steady fitting in the cap. The
interior of the plug I form hollow, showing a round opening at the top; in this
hollow or cavity, I compress a coiled wire spring, the upper end of which, presses
against the top of the cap, and the lower end, against the bottom of the hollow, in
the plug; but the spring is prevented from forcing the plug out, as its projecting
shoulder lodges upon the edges of a flat steel spring, which is formed oblong,
letter O shaped, with its ends rivetted together to a suitable shaped press plate (by
preference round). The oblong spring is placed in the cap, by being pressed
through an oblong square hole cut crossways near its lower end; the press plato,
and portion of the oblong spring, are left projecting outside the cap; whilst the
opposite curve, of the oblong spring, is secured to the inside of the cap by a rivet,

page_text: Thus, when the cap is forced on the mouth of a bottle or jar, the conical rubber
plug forces itself into the mouth, and, at the same time, the edges of the mouth
forces the oblong spring circle shaped, which allows it to pass the ridge on the neck
of the bottle or jar, The spring, returning to its normal shape, grips the neck
under the ridge, which prevents the coiled wire spring, behind the plug, from
removing the cap, In this position the bottle or jar is air tight stoppered, by the
simple action of forcing it on. To unstopper the bottle or jar the projecting press
plato is pressed, when the cap flies off, as the oblong spring is forced circle shape,
thus dislodging the grip from under the ridge of the bottle or jar, and allowing the
coiled wire spring to lift off the cap.

IMPROVED STOPPER FOR BOTTLES JARS AND OTHER RECEPTICALS
My invention relates to a simply constructed stopper for Bottles and Jars. The
objects of my invention are the production of simple air tight stoppers that can be
fixed on the bottle or jar by pressing on, and removed by pressing a projecting
piece at the side of the stopper. I construct the stopper in the following manner.
To the upper end of a piece of metallic tube (by preference brass) I secure a suitable
top thus forming a cap, in the internal upper part of this cap I place a plug of
suitable material (by prevence deft) or china the lower end of this plug I form
comical over which I stretch a piece of flexible rubber tube, that is held on by the
formation of a shoulder at the lower end of the plug round the upper part of the
comical plug I form a shoulder the edges of which give the plug a steady fitting in
the cap the interior of the plug I form hollow showing a round opening at the top
in this hollow or cavity I compress a coiled wire spring the upper end of which
presses against the top of the cap and the lower end against the bottom of the
hollow in the plug but the spring is prevented from forcing the plug out, as its
projecting shoulder lodges upon the edges of a flat steel spring which is formed
oblong letter O shaped with its end rivetted together to a suitable shaped press
plate (by preference) round the oblong spring is placed in the cap by being pressed
through an oblong square hole cut crossways near its lower end, the press plate and
portion of the oblong spring are left projecting outside the cap whilst the opposite
curve of the oblong spring is secured to the inside of the cap by a rivot. Thus
When the cap is forced on the mouth of a bottle or jar The comical rubber plug
forces itself into the mouth and at the same time the edges of the mouth forces
the oblong spring circle shaped which allows it to pass the ridge on the neck
of the bottle or jar the spring returning to its noumal oblong shape grips the neck
under the ridge which prevents the coiled wire spring behind the plug from
removing the cap in this position the bottle or jar is air tight stoppered by the
simple action of forcing it on To unstopper the bottle or jar the projecting press
plate is pressed when the cap flies off as the oblong spring if forced circle shape
thus disloding the grip from under the ridge of the bottle or jar and allowing the
coiled wire spring to lift off the cap flies off as tho oblong spring if forced circle
shape thus disloding the grip from under the ridge of the bottle or jar and allowing
the coiled wire spring to lift off the cap instead of forming the plug comical &
drawing thereon a piece of rubber tube that part of the plug can be left parallel & a
comical shaped rubber washer used as shown in the drawings a full sized coiled wire
spring may also be used in which case the hollow or cavity in the pul plug is
filled up.
In order to make my invention to be readly understood I will proceed to
describe the same by reference to the several Figures of the accompanying
drawings.
Fig 1. shows an elevation of Stopper with a portion cut away to show clearly
the interior construction. Fig 2. shows the relative positions of the parts when
the stopper is affixed on the bottle a is the cap or case 6 is the plug which is pressed
downward by the coiled wire spring c. d is the conical rubber washer on the plug
b. e is the oblong flat spring which prevents the plug from being forced out of the
cap a as one end is rivetted to the cap and the other end rests through an elongated
hole in the cap, and is rivetted to the round press plate marked f. Rivets markod g.

page_text: Thus when the cap marked a is forced on the mouth of a bottle or jar, the conical
rubber washer marked d forces itself into the mouth and at the same time the edges
of the mouth forces the oblong spring marked e circle shaped which allows it to
pass the ridge on the neck of the bottle or jar, the spring marked e returning to
its normal oblong shape grips the neck of the bottle marked h under the ridge
which prevents the coiled wire spring marked c behind the plug marked 6 from
removing the cap a in this position the bottle is air-tight stoppered by the simple
action of forcing it on, To unstopper the bottle or jar the projecting press plate
marked fis pressed when the cap a flies off as the oblong spring e is forced circle
shape thus dislodging the grip from under the ridge of the bottle or jar and
allowing the coiled wire spring c to lift off the cap. a.
What I wish to claim and secure, is the use of an oblong flat spring for the uses
as specified and the manner in which the same operates in conjunction with a plug,
spring and cap or any mere modification thereof.
In witness whereof I the said John Jackson have hereunto set my hand and
seal this day of 30th October in the year of our Lord 1883.
