Improvements in Stoppers for Does
We, HARRY ALBERT GRIFFITHS and RICHARD HANSON GRIFFITHS, of the Acme
Stopper Com any, 63, Lionel Street, in the City of Birmingham, Manufac-
turers, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of the metallic heads for corks in
the production of bottle and the like stoppers of the type commonly known as union
stop: ers, our object being to make such heads of a cylindrical or cheese shape
without the use of the internal cups hitherto employed.
In the manufacture of our improved union stoppers we form the heads from
discs or blanks of tinned plate or other suitable material pressed to a cup like
shape and having their circular sides or perimeters milled or corrugated in the
ordinary manner. Before inserting the cork within the metallic cup we form a
fine circular groove preferably around the interior of the cup at the position
where the metal is to be turned in to permit of the closing of its edge into the
cork for the attachment of the two parts in the ordinary manner. By the for-
mation of the said groove we are enabled to readily and evenly turn in the metal
at right angles to the body of the cup and thus to form a true cylindrical or
cheese shaped head.
We preferably form the grooves in the cups by means of a specially arranged
machine comprising a running headstock fitted with a holder for the reception
of the cups and a circular grooving tool mounted loosely on a stem carried in a
suitable head-stock and arranged for reciprocation by a lever. In addition to
its reciprocation by the action of the lever on the sliding stem the grooving tool
is also arranged to be moved slightly in a vertical direction in order that when
the cup is placed on the tool and carried therewith into the holder on the running
head-stock the V shaped working edge of the tool can be forced against the
metal of the cup for the purpose of forming the groove therein. The cutting
tool is free to revolve with the cup holder and to give freedom of movement, we
interpose a bearing ball between the interior of the tool and the extremity of
the stem on which it is mounted.

We, HARRY ALBERT GRIFFITHS and RICHARD HANSON GRIFFITHS, of the Acme

page_text: turers, 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 relates to the construction of the metallic heads for corks in
the production of bottle and like stoppers of the type commonly known as union
stoppers, our object being to make such heads of a cylindrical or cheese shape
without the use of the internal cups hitherto employed.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to:-
Figure 1 is an elevation, Figure 2 a section, and Figure 3 a plan of the cup
shaped metallic disc or blank from which we form the cylindrical stopper head.
Figure 4 is an elevation of the complete stopper.
In the manufacture of our improved union stoppers we form the heads from
single discs or blanks of tinned plate or other suitable material pressed to a cup.
like shape and having their circular sides or perimeters milled or corrugated in
the ordinary manner. Such a cup shaped metallic disc is shown by Figures 1, 2,
and 3. Before inserting one end of the cork A (Figure 4) within the metallic
cup we form a fine circular groove around the crowns or ridges of the corru-
gations both on the interior and exterior of the cup, or around the interior or
exterior alone, at the position as B (Figures 1 and 2) where the metal is to be
turned in to permit of the closing of its edge into the cork for the attachment of
the two parts in the ordinary manner. By the formation of the said groove we
are enabled to readily and evenly turn in the metal at right angles to the body
of the cup and thus to form a true cylindrical or cheese shaped head as shown
at Figure 4.
The operation of grooving (which is termed "bezzling") we preferably per-
form in a machine comprising an ordinary running headstock fitted with a holder
for the reception of the cups, and a circular disc shaped grooving tool mounted
loosely on a stem carried in a suitable head-stock by which the bevelled working
edge of the tool can be pressed against the rotating disc; but we make no claim
to any particular form or type of grooving or "bezzling" machine or appliances.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. Stoppers for bottles and other like purposes having cylindrical or cheese
shaped heads formed from single metallic dises or blanks, substantially as
described.
2. In the manufacture of union stoppers the grooving or
metallic heads, substantially as and for the purpose described.
