PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Stoppers for Bottles and
other Hollow Vessels.
I FRANK BRIDGE of 9 Frith Street, Soho Square in the County of Middlesex,
Cork Merchant do hereby declare the nature of this invention to be as follows:-
The invention has for its object the combination of a cork cylinder or other form of
stopper with a head piece of a material not hitherto used for such purpose which
material is cheap, elastic and is capable of being firmly and securely connected with
the cork body.
"Lincrusta Walton" or other
For this purpose I employ the material known as
material of a closely similar character, which is capable of being moulded and
compressed around the cork body and thereby securely connected thereto, thus forming
a somewhat elastic head piece which is also completely impermeable.

Improvements in the Manufacture of Stoppers for Bottles and
other Hollow Vessels.
I, FRANK BRIDGE of 9 Frith Street, Soho Square in the county of Middlesex,
Cork Merchant, do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained in and
by the following statement :-
The invention has for its object the combination of a cork cylinder or other form of
stopper with a head piece or cap of a material not hitherto used for such purpose which
material is cheap,.elastic and is capable of being firmly and securely connected with
the cork body.
For this purpose I form the head piece or cap of the material employed in the
manufacture of Lincrusta Walton" or other material.of a similar character, which
is capable of being moulded into the desired form.
The material I have used and have found to answer well in carrying my invention
into effect is prepared from the following ingredients and in the manner hereinafter
stated.
I first prepare a cement consisting of
Oxidized Oil
Kowrie Gum
Resin
15 lbs.
20 "
15 37
The oxidized oil above referred to is preferably prepared in the manner described in
the specification of Letters Patent granted to Frederick Walton dated January 27, 1860
No. 209 and is similar to that used in the mauufacture of linoleum, oilcloth but I do
not confine myself to the said method of producing solidified oils for use as above
stated as for instance the solidified oils produced by long and continuous boiling at a
high temperature will answer the purpose.
When employing this latter method of solidifying oils the articles made from
composition containing the same will require to be hardened in a chamber heated to
from about 100 degrees to 120 degrees Fahrenheit.
The method of combining the above named materials is as follows; the oil, gum
kowrie and resin are put into a steam heated pan at a temperature of from 300 to
350 degrees Fahrenheit until under motion produced from stirrers mounted in the pan,
the mass runs down into a cement similar in consistency to an adhesive dough.
In the manufacture of a composition of a buff colour for the purposes of my
invention I preferably employ the following materials combined in the proportions and
in the manner stated.
Cement prepared as above stated
Wood fibre
Whiting
Permanent white, dry,
Paraffin Wax
Middle Chrome
30 lbs.

page_text: The above mentioned ingredients are mixed in a dough or roller mixing machine
until thoroughly incorporated. The colour of the composition may be varied by
employing other coloring matters than those above mentioned.
The composition is rolled into sheets of a convenient size and substance, blanks are
cut out of this sheet by the aid of suitable cutters and such blanks are afterwards
moulded in a screw or other press into the desired form of head piece or cap. The
construction of presses and moulds suitable for the above purpose is well known.
Head pieces or caps constructed of material of the above or of similar character
may be moulded in position on the cork body and thereby securely connected thereto
or they may be separately moulded and when dry or set they may be cemented on to
the cork body by means of any suitable cement.
Stoppers formed of cork provided with head pieces or caps constructed of materials
such as are herein referred to are completely impermeable and are not liable when
driven into a bottle to break the neck thereof by the head piece or cap coming into
contact with the edge of the bottle neck as being somewhat elastic it does not offer an
unyielding or rigid substance to the hottle neck.
I would here remark that although I prefer to employ the composition above
described in the manufacture of head pieces or caps of stoppers I do not confine
myself to the exact proportions and materials stated as such may be varied without
departing from the peculiar character of my invention provided the composition is of
an imperineable and slightly elastic character.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed 1 declare that what I claim is :-
1. The improvements in the manufacture of stoppers for bottles and other hollow
vessels substantially as herein described and for the purpose stated.
2. The manufacture of stoppers with head pieces or caps substantially of the
character herein described.
