IMPROVEMENTS IN TOOLS FOR MOULDING THE HEADS OF BOTTLES
Year: 1885

page_text: I, JOSEPH DEEKS of 15 Grove Road Brixton in the County of Surrey Bonded
Carman do hereby declare the nature of my invention for "IMPROVEMENTS IN
TOOLS FOR MOULDING THE HEADS OF BOTTLES" to be as follows:-
The object of the invention is to form an improved tool for moulding the heads
of such bottles as are required to have an annular groove of a uniform depth
formed around their interior or which are otherwise required to be moulded
internally to a larger diameter than the mouth.
For this purpose I construct spring tongs similar to those ordinarily used for like
purposes but with a central core or plug of smaller diameter than the diameter to
which the mouths of the bottles are to be moulded. The core or plug may be
either solid or divided into two or more parts and I form the tongs in such manner
that when they are compressed so as to move the dies or jaws which are carried at
the ends of the two arms of the tongs towards one another the single core or the
parts of the divided core shall be made to slide or move outwards away from the
central line of the tool and in order to ensure that the interior of the mouth and
the depth of the groove of all bottles made with such tools shall be of uniform size
I in addition construct the tool in such manner that this outward movement of the
core or plug or the parts into which it is divided shall be completed before the jaws
which mould the exterior of the mouth of the bottle close upon the glass or metal
to be operated upon and in such manner that when the tongs are released the parts
of the plug shall return to their first position so that they can be then withdrawn
from the mouth of the bottle.
If a solid core or plug is used it may if desired be fixed in an eccentric position
instead of being moved into such position when the tongs are being closed.
In this way if the acting side of the core or of the parts into which it is divided
are so shaped as to form an annular groove around the interior of the heads of
bottles all the bottles will be manufactured with the head of the same internal
diameter and with the groove of the same depth and size.

I, JOSEPH DEEKS of 15 Grove Road Brixton in the County of Surrey Bonded
Carman 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 the invention is to form an improved tool for moulding the heads
of such bottles as are required to have an annular groove of a uniform depth
formed around their interior or which are otherwise required to be moulded
internally to a larger diameter than the mouth.
For this purpose I construct spring tongs similar to those ordinarily used for like
purposes but with, a central core or plug of smaller diameter than the diameter to
which the mouths of the bottles are to be moulded.
The core or plug may be either solid or divided into two or more parts and
I form the tongs in such manner that when they are compressed so as to move the
dies or jaws which are carried at the ends of the two arms of the tongs towards
one another the single core or the parts of the divided core shall be made to slide
or move outwards away from the central line of the tool and in order to ensure
that the interior of the mouth and the depth of the groove of all bottles made with
such tools shall be of uniform size I in addition construct the tool in such manner
that this outward movement of the core or plug of the parts into which it is
divided shall be completed before the jaws which mould the exterior of the mouth
of the bottle close upon the glass or metal to be operated upon and in such manner
that when the tongs are released the parts of the plug shall return to their first
position so that they can be then withdrawn from the mouth of the bottle.
In this way if the acting side of the core or of the parts into which it is divided
are so shaped as to form an annular groove around the interior of the heads of
bottles all the bottles will be manufactured with the head of the same internal
diameter and with the groove of the same depth and size.
In the drawings hereunto annexed I have shown a tool formed as above described.
The central core or plug of this tool is shown to be divided into two parts capable
of being moved towards or away from one another.
Figure 1 is a plan view of the tool-Figure 2 is a longitudinal section of the
divided core or plug and the parts which carry it. Figure 3 is a face view of the
disc or "swiller" plate and of the slides which carry the two parts of the divided
core-Figure 4 is a face view of the disc or "swiller" plate with the slides removed.
Figure 5 is a face view of a rotating disc by which the slides are moved towards or
away from one another.
AA are the arms of tongs carrying at their ends dies B for moulding the exterior
of the heads of bottles in the ordinary manner-C is the central stem having fixed
to its end the disc or swiller plate D-E E are two slides capable of being moved
to and fro along a dovetail groove formed across the face of the "swiller "plate D-
FF are the two parts of the divided plug or core one carried by each slide E
Each slide has also fixed to it a pin G—these pins pass through straight slots D¹ in
the swiller plate and enter other slots H¹ in a disc H which can turn around the
screw pin I that carries the swiller plate.

page_text: The disc H at a point near its circumference has a pin H' fixed in it which is
coupled by a link J to a pin carried by one of the arms A of the tongs. In this
way whenever the tongs are closed a partial turn is given to the disc H. When
the tongs are open the disc H is in the position shown at Figure 5 with the pins G
passing through those ends of the slots H¹ which are nearest to the centre of the
disc. As the tongs are closed and the disc H thereby turned the pins are by the
eccentric portions of the slots H' first caused to move away from one another after-
wards the pins pass into portions of the slots which are concentric with the disc.
The two portions of the divided plug or core F are thereby first moved apart from
one another as the tongs are being closed and then when they have been moved
apart to the required extent they are retained in this position whilst the outer
dies B complete their inward movement towards one another.
The core and "swiller" are as usual kept in a central position between the
jaws B by means of a slotted quadrant K which can slide freely along the stem C
and which at each end has a slot in it through which passes a pin carried by one
of the arms of the tongs.
In place of the core F being divided into two parts it might be divided into
three or more parts each to be carried by a separate radial slide E or a single slide
and portion of a core might be employed if desired.
The core shown in the drawings is of a forin suitable for moulding a groove all
around the interior of the head of a bottle but it might be of other form according
to the form to which it may be required to mould the interior of the head.
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 construction of tools for moulding the heads of bottles in such manner
that the central plug or core or parts into which it is divided is or are caused to
slide or move outwards away from the centre of the "swiller" plate as the tongs
are closed and in such manner that they complete their outward movement before
the tongs are fully closed substantially as described.
2. The combination with the "swiller" plate of tools for moulding the heads of
bottles of a slide or slides E carrying the plug or core or parts into which it is
divided and a slotted disc H caused to turn when the tongs are closed so as to then
move the plug or core or parts into which it is divided away from the centre of the
swiller plate substantially as described.
3. The construction of tools for moulding the heads of bottles substantially in
the manner herein before described and illustrated in the drawing annexed.
