A New or Improved Mould for Casting Stoppers for Bottles and
the like.
We, JAMES HICKLING 18 Ancliff Street Stepney, London, Retired Naval
Brigade's Man, and THOMAS SLATER "The Hare "Brick Lane, E.C. Wine
and Spirit Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved mould for casting stoppers for
bottles and the like, and consists in so constructing and arranging the mould
that the screw and head of the stopper are cast without a seam and the same
is carried out as follows:-The two parts of the mould which form the head
and screw of the stopper are formed in one piece or solid, and the contracted
portion between the head and screw is formed between movable divided parts
of the mould said movable divided parts being between the part of the mould
which forms the screw threaded portion of the stopper and the part which forms
the head.
The part which forms the head of the stopper is provided with cores or
projections of suitable cross section which thus form apertures in the heads of
the stopper and facilitate their removal from the mould and also provide a means
of readily screwing or unscrewing same from bottles, a key being employed for
this purpose.
The glass or metal is forced into the mould through suitable apertures by any
any well known and convenient means such as a piston or plunger working in a
receptacle containing the molten glass or metal.
The movable divided parts of the mould permit of the contracted part of the
stopper being formed, and owing to the divided parts being movable the stopper
can be removed from the mould which could not be done if the divided parts
were immovable owing to the diameter of the screw threaded portion of the
stopper being greater than the contracted portion.

Ecrewed portion of the stopper is formed.

Referring to Figures 1 to 5 a is a hinged or pivoted frame carried as shown in
the bearing c by means of the pivot pin h is the part of the mould in which the
screw threaded portion of the stopper is cast in the cavity or matrix j. "The part r
or groove on the stopper Figure 6 and which carries the usual washer is formed at
the part n between the movable pieces fand f'. The shape of the groove
atr Figure 6 is dependant upon the shape of the aperture at n so that a half of
said aperture is formed in the parts' ff ff that is one half of said aperture in
each part. "m is a pin for ensuring the correct position of the parts ff. ff
when together as shown in Figure 5. The parts ff and f1 f are pivoted at o
to the part h so that they may be separated as shown by the arrows 1. The glass
or metal is placed in a molten state in the frame a and the piston or plunger i is
employed to force the glass or metal through the apertures d in' the part 'which
forms the screw thread. 'k is a core or projection of suitable cross section'siich as
triangular and 'which forms a recess & in the head of the stopper into which a key
may be inserted for facilitating the removal of the stopper from the part of
mould; or inserting or removing same from a bottle when in use. The frame a
may be turned up upon the pivot when required. The parts 9 & h being each
formed in one piece it will be seen that there will be no seam on the screwed
portion p of the stopper or tipon the head of same 'which "may be milledsas' shown
at t. By removing the part from the part g the heads of the stoppers are
removed from-the cavities or matrices & and 'the parts ff and fare seperated
and thus the stopper may unscrew from the part h. e'e are suitable handles for
use when raising the part or section h.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The new or improved mould substantially as described 'and 'illustrated.
2. In moulds for casting stoppers for bottles, two parts or sections formied'so as
to have seamless cavities or matrices in which the screw and head of the stopper
are cast, one part or section having the cavities or matrices for forming the screw
thread upon the stopper, the other part or section having the cavities or matrices
for forming the head of the stopper said cavities or matrices having cores or
projections for forming a recess in the head of the stopper, movable sections or
parts pivoted to the sections or parts forming the screw thread upon the stopper
and having apertures which form the matriees for that portion of the stopper
which is between the screw thread and the head the position or said pivoted
sections or parts being regulated by studs or pins a pivoted or hinged frame
which forms a receptacle for the molten glass or metal which is forced through
suitable apertures by means of a piston or plunger into the cavities or matrices in
which the stopper is.cast.
