Date of Application, 30th May, 1896
Improvements in Stoppers for Bottles, Jars, and the like.
I ROWLAND DOUGLAS TODD, of the Birmingham Stopper Company, 80 Buckingham
Street, Birmingham, in the County of Warwick, Engineer, do hereby declare the
nature of this invention to be as follows:---
This invention for improvements in stoppers for bottles, jars and the like, relates
to that class of stopper known as lever stoppers in which a rubber or similar elastic
ring is placed round the body of the stopper between two discs, that can be forced
together by means of a lever mounted on the stopper to bulge out the rubber and
so enlarge the stopper to fit tightly in the neck of the bottle or the like. Stoppers
of this class have usually been made of metal that is liable to corrode and thus
injure not only the stopper but also the contents of the bottle, and this invention
has for its object to construct a stopper that shall not be liable to corrode, and con-
sists in constructing that part of the stopper that is liable to come in contact with
the contents of the bottle of glass, porcelain or other similar material, or to cover
the said exposed parts of the stopper with a non-corrodable material such as parch-
ment.
In one way of carrying out this invention the base of the stopper is made of glass,
porcelain or the like with a flange to retain the lower edge of the elastic ring and the
bearing or support for the lever pivot is moulded in the material or it may be
secured in any suitable way in a recess moulded in the upper surface of the base.
In another form an envelope of parchment or similar material is formed to a
shallow circular box-shape and is placed over an ordinary metal lever stopper.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Stoppers for Bottles, Jars, and the like.
I, ROWLAND DOUGLAS TODD, of the Birmingham Stopper Company, 80 Buckingham
Street, Birmingham in the County of Warwick, England, 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:-
This invention for improvements in stoppers for bottles, jars and the like, relates

page_text: to that class of stopper known as lever stoppers in which a rubber or similar elastic
ring is placed round the body of the stopper between two discs, that can be forced
together by means of a lever mounted on the stopper to bulge out the rubber and
so enlarge the stopper to fit tightly in the neck of the bottle or the like; and in
which that part of the stopper that is liable to come in contact with the contents
of the bottle, is constructed of glass, porcelain or other similar material. This
invention consists firstly in the manner of fixing the pillar in the base, and secondly
in covering the said exposed parts of a metal stopper with a non-corrodable material
such as parchment.
In one way of carrying out this invention the base of the stopper is made of glass,
porcelain or the like with a flange to retain the lower edge of the elastic ring, and the
bearing or support for the lever pivot is moulded in the material or it may be
secured in any suitable way in a recess moulded in the upper surface of the base.
In another form an envelope of parchment or similar material is formed to a
shallow circular box-shape and is placed over an ordinary metal lever stopper.
In the accompanying sheet of illustrative drawings
Figs. 1 and 2 are sections of a stopper constructed according to this invention
showing the stopper in position in the bottle, Fig. 1 showing the stopper loose and
Fig. 2 when tightened or bulged.
Fig. 3 is a half plan and half sectional plan at x x Fig. 1 and Fig. 4 is a plan of
Fig. 2.
Fig. 11 is a sectional elevation of a cap or capsule for a stopper.
The rubber or elastic ring a is placed round the body b of the stopper between
the flange c on the body and the loose flange d. A spring plate e through which
passes the pillar f secured in the body b bears on the loose flange d. The stopper
lever g is inserted in the hook of the pillar f as shown in Fig. 3 when the plate e
is pressed down and in drawing it over to the position shown in Fig. 4, the cam
ends h bear on the spring plate and press it down so bulging the stopper.
Now according to this invention, the pillar f is made of metal and with a head i
and the glass body is cast round the head, so that the pillar will be firmly embedded
in the body.
In the modification shown in Figs. 5 to 8, the pillar is formed in one with the
body b and has a central hole. In this case the lever g is secured by a pin passing
through the cam ends and the hole of the lever.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a lever stopper having a glass, porcelain, or similar base, a pivot pillar
fixed in the base, substantially as described with reference to the drawings.
2. The improvements in stoppers for bottles, jars and the like, substantially as
described with reference to the drawings.
