PROVISIONAL SPECIFICATION.
A Method of and Apparatus for Making Glass Ball Stoppers and
Solid or Hollow Articles from Molten Glass or Suitable Plastic
or Molten Material.
I JOSEPH BENJAMIN ADAMS of Number 10 George Street Barnsley in the County
of York Engineer do hereby declare the nature of this invention to be as follows
The object of my invention is to make from glass clay or any other suitable
substance in a molten state or of a plastic character articles such as glass ball stoppers,
balls, marbles, bottle stoppers, salt cellars or any other kind of articles to which the
method is suitable, and for these purposes I construct an apparatus made of steel
or iron or other suitable material which apparatus can be varied in size and
configuration that is to say, the shape or modifications of the moulds slides, power
or execution of the method for making the different articles without departing from
the method of my invention and also can be modified to suit the different classes of
material employed to produce such articles.
:
The apparatus or machine which 1 construct and employ for the purposes herein
explained consists of a container of an oblong shape or of any other suitable shapė
and of a sufficient size to suit the number of articles required to be made at one
operation and to hold sufficient material in its interior (such interior being made in
such a way as to allow of the surplus material being removed after the operation).
Circular or other suitable shaped holes are drilled or made in the sides of and running
through the interior of the container, so that the holes on each side of such interior
of the container shall be mechanically opposite to each other, such holes being for the
purpose of receiving round or other suitably shaped spindles, having semi-circular or
other suitably shaped impressions or moulds formed at one end of each of them which
impressions or moulds can be either turned or otherwise placed thereon by any suitable
means. Thus by placing the two semi-circular inoulds together a complete mould will
be formed, care being taken that each semi-circular or other shaped mould (attached
to such spindles as aforesaid) is tapered to a point on the end or wherever such
mould is closed, so that when the article is made by such mould there will be no
projection thereon or as slight a projection as possible, that is to say, the sharper
the edges are made on each semi-circular or other shaped mould, the less projection
there will be upon the article produced thereby. When such moulds are closed I
provide a stop attached to the said spindle or spindles for the purpose of protecting the
sharpened edges of such semi circular moulds from coming in absolute contact with
each other, each semi-circular mould being so arranged that the edges thereon exactly
touch each other, but without pressure, the pressure being transferred from such
edges to the stops provided as aforesaid. The molten or plastic material being
placed in the interior of the container to make the article or articles required the
spindles (having the semi-circular or other shaped moulds thereon) being made to
slide freely through each hole in the sides of the container meet in or about the
centre of the interior of the same. Thus by the two semi-circular moulds with
sharpened edges meeting or closing and being surrounded with molten glass or other
plastic material previous to such meeting or closing and through such cause the
interior of the container and such impressions or moulds therein becomes free from
air through such molten glass or other plastic material having displaced same, and the
above moulds meeting together and retaining the necessary quantity of molten or
other plastic material to make the article required, the sharp edges thereon cut off
and displace any surplus material attached to the bevelled edges of such moulds or
their spindles and thereby forms a complete round ball stopper without a stem.
After such operation by pushing the spindles through any of the before mentioned

page_text: holes at either side of the interior of the container, the surplus metal or other
plastic material surrounding such spindles remains in the interior of the container
and when the spindles are pushed to the exterior of the container through the holes
therein, the semi-circular or other moulds can be reopened and the ball, stopper or
other article released and dropped into a suitable receptacle.
The spindle or spindles with the semi-circular or other shaped moulds attached
thereto can be actuated in and out of the interior of such container by any suitable
power such as hand power by levers or screws, hydraulic compressed air, or steam
power.

COMPLETE SPECIFICATION.
A Method of and Apparatus for Making Glass Ball Stoppers and
Solid or Hollow Articles from Molten Glass or Suitable Plastic
or Molten Material.
I JOSEPH BENJAMIN ADAMS of No. 46 Sackville Street Barnsley in the County of
York Engineer 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 :-
The object of my Invention is to make from glass, clay, or any other suitable sub-
stance in a molten state or of a plastic character articles, such as glass ball stoppers, balls
marbles bottle stoppers salt cellars, or any other kind of articles to which the method
is suitable, and for these purposes 1 construct an apparatus made of Steel or Iron or
other suitable material, which apparatus can be varied in size and configuration,
that is to say, the shape or modifications of the moulds, slides, power or excution of
the method for making the defferent articles without departing from the method, and
my invention and also can be modified to suit the different classes of material
employed to produce such articles The apparatus or machine which I construct and
employ for the purpose herein explained consists of a container of an oblong shape
or of any other suitable shape and of sufficient size to suit the number of articles
required to be made at one operation and to hold sufficient material in its interior
(such interior being made in such a way as to allow of the surpius material being
removed after the operation) Circular or other suitable shaped holes are drilled or
made in the sides of and running through the interior of the container, so that the
holes on each side of such interior of the container shall be mechanically opposite to
each other, such holes being for the purpose of receiving round or other suitable
shaped spindles, having semi circular or other suitably shaped impressions or moulds
formed at one end of each of them, which impressions or moulds can be either
turned or otherwise placed thereon by any suitable means Thus by placing the two
semi circular moulds together a complete mould will be formed, care being taking
that each semi circular or ther shaped mould (attached to such spindles as aforesaid)
is tapered to a point on the end, or wherever such mould is closed, so that when the
article is made by such mould there will be no projection thereon, or as slight a
projection as possible, that is to say the sharper the edges are made on each semi
circular or other shaped mould, the less projection there will be upon the article
produced thereby.
When such moulds are closed I provide a stop attached to the said spindle or
spindles for the purpose of protecting the sharpened edges of such semi circular
moulds from coming in absolute contact with each other each semi circular mould or
moulds being so arranged that the edges thereon exactly tuch each other but without
pressure, the pressure being transferred from such edges to the stops provided as
aforesaid The molten or plastic material being placed in the interior of the container
to make the article or articles required, the spindles (having the semi circular or
other shaped moulds thereon) being made to slide freely through each hole or holes
in the sides of the container meet in or about the centre of the interior of the same,

page_text: Figure 1 illustrates an apparatus or machine suitable for carrying out my invention
into practical effect shewing a sectional elevation of the parts such as a Container B
with holes therein also Spindles E. E such Spindles having semi-circular moulds at
one end of each and placed in the interior of such Container and also shews the
Spindles so arranged that material can be placed in such interior of the Container for
the purpose of making the articles herein mentioned.
Figure 2 illustrates an apparatus or machine similar to that of Figure 1 with the
exception that the Spindles meet in the centre of the Container, that is to say, if the
material is placed in the centre of the Container when the Spindles are in the position
as shewn in Figure 1, by closing the Spindles as shewn in Figure 2, they make a
complete article as herein mentioned.
Figure 3 illustrates an apparatus or machine similar to that shewn in Figures 1
and 2 with the exception that the Spindles are moved and closed together with the
material therein through one of the holes in the Container from the interior to
exterior. At this stage the article is ready for delivering.
Figure 4 illustrates an apparatus or machine similar to that shewn in Figures 1.
2 and 3 excepting that it shews a means of delivery of the article in the centre of
the Spindle moulds and from such Container as therein referred to, that is to say,
when the Spindles are moved to the exterior of the Container, the Spindles with
the moulds at the ends are opened and the article is released and falls into a suitable
receptacle.
With reference to Figure 1. A in Figure 1 is a Guide bed for the purpose of
keeping the Spindle or Spindles in their proper place or places B is a Container
shewing the holes as before mentioned herein for the purpose of receiving the
Spindle or Spindles with moulds at the end of each, each of which holes in such
Container being made opposite to the other, so as to make a perfect article. C is a
Guide bed for the purpose of keeping the Spindle or Spindles on the opposite side of
the Container in position or proper place D bolts which fasten the upper part of
Guide bed. F is a bed or frame with suitable legs to which the other parts are fixed

page_text: or fastened in a suitable manner H is a loose bottom fastened to a suitable rod for
the purpose of throwing the waste material out of the interior of the Container after
the operation is completed. I in Figure 2 is a ball or other article in the interior of
the Spindle moulds in the centre of the Container. I in Figure 3 is a ball or other
article in the centre of the Spindle moulds and at the exterior of the Container ready
for delivery. I in Figure 4 is a ball or article delivered after the Spindle moulds
have been forced to the exterior of the container and opened. K in Figure 5 is a
box or receptacle for the purpose of receiving the articles made by the machine J in
Figure 5 is a piece of iron or other material to guide the ball or other article into
the receptacle.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a method and apparatus or machine the combination of a Spindle and
moulds with a Container having holes through the same to receive such Spindle
moulds and so arranged that by placing molten.. glass into the interior of such
Container or its equivalent, the Spindle moulds become filled with such molten glass,
and by the movement of either of such Spindle moulds or the Container through the
holes in the Container which the Spindle moulds slide into from the interior of the
Container to the exterior thereof, making and delivering a Glass ball stopper without
a stem, thus saving the expense of grinding off such stem for practical use as herein
specified and set forth.
Second. In a method and apparatus or machine the combination of a Container or
its equivalent having hole or holes running through same from exterior to exterior
so as Spindles with moulds or impressions thereon may meet in the centre or interior
of such Container and punch or cut out or make any article or impression from any
material soft or pliable enough for the purpose and delivering same out of such
machine by pushing or drawing such Spindles with moulds or impressions thereon
through the aforesaid holes from the interior of the Container to the exterior as
herein specified and set forth.
