We, CESAR FREEMAN COHEN, and SAMUEL FREEMAN COHEN, trading together
under the style or firm of Cohen Brothers, of 438 Caledonian Road, in the County of
Middlesex, Mineral-Water Manufacturers, do hereby declare the nature of our Invention
to be as follows:-
-
Our improvements in stoppers for bottles consist first, in the construction of the
stopper itself and secondly, in a method of securing the said stopper to the covering
plate without the use of rivets, solder, or any kind of adhesive material.
According to our Invention, we construct the stopper proper of ebonite, wood,
porcelain, or other hard substance, and we give to it, by preference, the shape of a
stud, that is to say, it has a head connected to a base by means of a shank, the head
portion, for the purpose of our invention, being of larger dimensions than the base,
a groove being formed between the head and the base, the purpose of which will be
hereinafter explained. The stopper thus constructed is inserted and securely held in
the covering plate, which is made as follows.
We punch, or otherwise stamp a circular opening in the said covering plate in such
a manner as to leave, on the under surface thereof, a circular rim, or flange standing
nearly perpendicular to the plane of the said plate. Into the opening, thus formed,
we place the stopper constructed as aforesaid.
The circular rim, or flange, above described is then, by means of a suitable machine,
or appliance, turned in, so as to embrace the under surface of the head portion of
the stopper, and thus firmly secure the stopper to the covering plate, without the use
of rivets, etc.
An india rubber ring is then slipped into the groove formed between the head and
the base of the stopper, and this ring, at the same time, is caused to fit partially over
and upon the rim, or flange, above described, so that a tight joint is formed in the
bottle neck when the stopper is inserted therein.

page_text: We CÆSAR FREEMAN COHEN, and SAMUEL FREEMAN COHEN, trading together
under the style or firm of Cohen Brothers, of 438 Caledonian Road, in the County
of Middlesex, Mineral Water Manufacturers 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, reference being had to
the accompanying drawings and to the letters and figures marked thereon, that is
to say :-
Our improvements in stoppers for bottles are more especially applicable to those
stoppers affixed to bottles containing aerated liquids, beer, &c., and relate, first, to the
construction of the stopper itself, and secondly to a mode of securing the said stopper
to the covering plate, without the use of rivets, solder, or any kind of adhesive
material, as now practised, thereby obviating the chance of fracture of the stopper,
when fitting the same, by rivets, to its covering plate, or when closing the bottles,
and thus economizing time and material, and reducing the cost of manufacture.
And in order that our invention may be readily understood, we proceed to describe
the same with reference to the accompanying drawings in which:
Fig. 1 is a plan of one of the blanks from which the covering plate is formed, the
dotted lines indicating where the opening for the passage of the stopper is to be
punched. Fig. 2. is an edge view of the said covering plate shewing the opening
punched, and a flange or ring formed. Fig. 3 shews in plan the covering plate
after the opening has been punched, the dotted circle indicating the rim or flange
above mentioned. Fig. 4 is a view of the stopper proper, and Fig. 5 a plan of a
rubber ring for use therewith. Fig. 6 shews a vertical section of the covering
plate after the rim or flange has been curved or turned in, and the stopper in
position, but unprovided with the rubber ring. Fig. 7 is an elevation of the
covering-plate, stopper, and rubber ring complete. Fig. 8 is a general view of the
covering plate and stopper, as applied to a bottle, and shewn closed.
According to our Invention, we construct the stopper proper A, of ebonite, wood,
porcelain or other hard substance, as usual, but we give to it, by preference, the
shape of a stud as clearly seen in figs. 4, 6, 7, and 8, that is to say it has a head a,
connected to a base a', by means of a shank ax, the head portion a, for the purpose
of our Invention being of larger dimensions than the base, and a groove a² being
thus formed between the head and the base, the purpose of which will be hercin-
after explained. The stopper thus constructed is inserted and securely held in the
covering plate B which is made as follows:-
:-
We punch or otherwise stamp a circular opening (fig. 3) in the said covering
plate in such a manner.as. to leave, on the under surface thereof a circular rim or
flange standing nearly perpendicular to the plane of the said plate. Into the
opening thus formed, we place the stopper, as shewn in fig. 6.

page_text: The circular rim or flange b' is then (by means of any suitable machine or appliance)
turned in, as shewn in fig. 6, so as to embrace the under surface of the head a of the
stopper, and thus firmly secure the same to the covering plate, without the use of
rivets &c., and to prevent the said stopper from being extracted, either from the upper
or under side of the plate B.
An india-rubber ring C, preferably a flat one, is then, slipped over the base a¹,
of the stopper and lies in the groove a² formed by the head and base of the said
stopper.
This ring and stopper are thus permitted to accomodate themselves to the exact shape
of the mouth of the bottle, and to form a hermetic closure.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same may be performed, we declare that what we
claim is
1. The covering plate B having a rim or flange 6 formed on its under surface,
and adapted to retain the stopper while allowing it a certain amount of play,
substantially as specified and shewn.
2. The combination, with the above named covering plate, of the stud-shaped
stopper A, provided with a flat rubber ring adapted to embrace the rim or flange b,
and which ring allows the stopper to accomodate itself to the exact shape of the mouth
of the bottle, substantially as described and shewn,
3. The improved construction of stopper for bottles, whereby the use of rivets,
solder, or adhesive medium is dispensed with, and the chance of fracture during the
manufacture of the stopper, and the filling of the bottles is obviated, substantially
as described and as shewn in the drawings.
