Improvements in and in the Manufacture of Bottle and other Stoppers.
We, CHARLES MONTAGUE SMITH and BERNARD RINTEL SIMMONS, both of 63,
Northampton Street, Birmingham, in the County of Warwick, Die Sinkers and
Tool Makers, 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:-
Our invention which has for its object improvements in bottle and other
stoppers and in the manufacture of the same refers more particularly to stoppers
for beer and stout bottles by which we produce a metal stopper preferably of
aluminium which is of clean appearance cheap to produce and lends itself more
generally to advertisement than the composition screw stoppers now in general
use for the same purpose.
In order that our invention may be clearly understood and more easily carried
into practise we have appended hereunto a sheet of drawings upon which we
have fully illustrated the nature of our said improvements and the mode of
carrying the same into effect.
Figure 1 is a view of the stopper complete.
Figure 2 is a section through the stopper complete.
Figure 3 is a plan of Figure 1.
Figure 4 is a similar section to Figure 2 but shewing the various parts con-
stituting the stopper separately and apart.
Figure 5 is a section shewing the stamping before forming the screw part
of the stopper.
Figure 6 is a sectional elevation through the tools for forming the screw part
of the stopper.
Figure 7 is an elevation of a press suitable for operating the tools for pro-
ducing the screw portion of the stopper.
Our stopper consists of the hollow metal screw A and metal top B both prefer-
ably made of aluminium with intermediate cupped disc C and in some case the
stiffening disc D. The screw part A of our stopper is formed by stamping or
pressing out the blank A¹ from sheet metal by any suitable means such blank
being then placed in the die F the interior of which is formed to the required
shape of the screw A as illustrated by a².
The top tool E is also shaped to enter the die F and is made smaller than the
die F to the extent of the thickness of the metal of the blank. The die Fis
fixed while the tool E is mounted on the plunger K which is provided with the
screw of exactly similar pitch to that on the stopper so that as the tool E
advances to the die it revolves and enters the die with a screwing movement at
the same time shaping the blank to the screw form of the die and tool or the
die may be made to revolve while the tool E is kept stationary.
When the tool E is withdrawn from the die F the screwed blank A is with-
drawn with it and can then be unscrewed off the tool ready for use in the
manufacture of the stopper.
In forming the stopper we take the screwed blank A and insert the cupped

page_text: liner C in the head and upon this we may place the steel stiffening disc D the
cap B which is stamped with any required design and advertisement being placed
over the whole, which are secured together by turning the edges of the cap B
over the top projecting part of the screw part A. Two, three or more grooves
being formed in the top part of the screw A in such a manner that they fit the
grooves formed in the head B and thus prevent any possibility of the head turning
on the screw.
We may vary the shape and arrangement of the head and may or may not use
the liner C or steel stiffener D) as may be desired and we may vary the mode of
attaching the screw A to the head B if so desired while in the manufacture of the
screw we may vary the arrangement of the various parts of the press or lathe
.without departing from the nature of our invention.
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:-
1st. The improved metallic stopper for bottles and for other similar articles con-
sisting of the screw part A formed from sheet metal in combination with the cap B
secured together with or without the intermediate stiffeners C and D substantially
as and for the purpose herein set forth and illustrated.
2nd. In the manufacture of screw stoppers for bottles and other similar articles
from sheet metal the combination of a recessed screw die F with a screw tool E
one of which is operated by a screw of the same pitch as the screw stopper sub-
stantially as and for the purpose herein set forth and illustrated.
Dated this 31st day of May 1899.
