page_text: I FRANCIS HENRY FEARNS of Valentine Cottage Peckham Rye in the County of
Surroy Manufacturer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF STOPPERS FOR BOTTLES AND SUCH LIKE VESSELS
to be as follows:―
"
At the present time bottles are now commonly formed with a screw thread at
the mouth of the neck for the stein of a stopper upon which a corresponding screw
thread is cut to screw into. These screw stoppers have commonly been made of
glass or vulcanite or other composition..
According to my invention I make the stem of the stopper with an outer
coating or covering of a metal such as tin or any other suitable metal which is not
liable to be acted upon by any liquid with which the bottle may be required to be
filled.
Preferably I make the body of the stopper of a plastic mixture of powdered
materials which become consolidated together upon the application of pressure and
heat.
"
I first place into that part of the mould in which the stem of the stopper is to be
moulded a previously formed thimble or lining of thin tin or other suitable metal.
I then fill the mould with the plastic composition and subject it to pressure and
heat, the thimble or lining of tin is thereby expanded into the mould and the
requisito screw thread is so moulded on its exterior whilst at the same time the
head of the stopper is moulded to the required form.
If desired the body of the stopper might be made from wood, glass or other
material and have an exterior coating of metal applied to it or the stem might
solely be composed of a hollow metal thimble having the requisite screw thread
moulded on it and secured or not as preferred to a head of any suitable material.
A ring of vulcanized india rubber or cork is as usually placed around the stem
of the stopper just below the head to make a tight joint between the stopper and
the sides of the mouth of the bottle.

I FRANCIS HENRY FEARNS of Valentine Cottage Peckham Rye in the County of
Surrey Manufacturer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF STOPPERS FOR BOTTLES AND SUCH LIKE VESSELS
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :—–
At the present time bottles are now commonly formed with a screw thread at
the mouth of the neck for the stem of a stopper upon which a corresponding screw
thread is cut to scrow into. These screw stoppers have commonly been made of
glass or vulcanite or other composition.
According to my invention I make the stem of the stopper with an outer
coating or covering of a metal such as tin or any other suitable metal which is not
liable to be acted upon by any liquid with which the bottle may be required to be
filled.
Preferably I make the body of the stopper of a plastic mixture of powdered
materials which become consolidated together upon the application of pressure and
heat.
I first place into that part of the mould in which tho atem of the stopper is to
he moulded a previously formed thimble or lining of thin tin or other suitable
metal, I then fill the mould with the plastic composition and subject it to pressuro
and heat the thimble or lining of tin is thereby expanded into the mould and
the requisite screw thread is so moulded on its exterior whilst at the same time the
head of the stopper is moulded to the required form.
If desired. the body of the stopper might be made from wood, glass or other
material and have an exterior conting of metal applied to it or the stem might
solely be composed of a hollow metal thimble having the requisite screw thread
moulded on it and secured to a head of any suitable matorial or formed in one picco
with a suitable head.
A ring of vulcanized india rubber or cork is as usual placed around the stem of
the stopper just below the head to make a tight joint between the stopper and thọ
sides of the mouth of the bottle.
Figure 1 of the drawings hereunto annexed sliews a side view of a stopper
constructed in the manner I prefer.
Figure 2 is a section of the same and Figure 3 a section of the mould in which
it is produced-filled with material ready to be compressed and Figure 4 is a section
of the mould when closed and after the material within it has been compressed and
moulded into the form of a stopper.
In Figures 1 and 2 A is the body of the stopper-B the metallic covering
surrounding its stem-C the ring of vulcanized india rubber placed around the stem
just below the hond.
In Figure 3 the dio or mould is shown with a metallic thimblo B placed within
it and with the requisite quantity of plastic compound filled in for forming the
body of the stopper. A measured quantity of the compound is filled into the mould
in a heated state the cover of the mould is then put on and is afterwards pressed
down in a powerful press the thimblo is thereby expanded into the mould and the
head of the stopper simultaneously moulded to the required form. The mould is
kept heated preferably by high pressure steam whilst it is in use. The upper parta
of the mould are made moveable so that when a stopper has been moulded they
may be taken away and the stopper be then screwed out from the lower part of
.the-mould.

page_text: The composition I prefer to employ is formed of a mixture of india rubber
shellac, gums and asbestos heated to about 200 degrees Fahrenheit, but other
compositions or materials might be used for the purpose, many such compositions
are well known and commonly used.
As before stated, a thimble of metal such as shewn in section at Figure 5 might
be formed separately and afterwards screwed and cemented on to the screw stem of
a stopper such as shewn at Figure 6 which may be of wood or glass or other
material. Or the metal stem of the stopper or a portion of it might be left.hollow
as shown at Figure 7.
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). The manufacture of stoppers for bottles and such like vessels with a screw
stém formed of or surrounded by a thimble of tin or other suitable metal
substantially as herein before described..
(2). The manufacture of stoppers for bottles and such like vessels with a screw
stem having an outer covering of metal by placing a metallic thimble into a mould.
of the required form and afterwards compressing into the mould and into the
thimble placed therein a plastic composition or material which will-consolidate
upon the application of pressure thereto substantially as described.
