We DAN RYLANDS of Hope Glass Works Stairfoot, near Barnsley, in the County
of York, Glass Bottle Manufacturer, and BENJAMIN STONER, of No. 2, Dearne
Terrace, Stairfoot aforesaid mechanic, do hereby declare the nature of this invention
to be as follows:-
According to our present invention we form by means of tools a screw thread on the
outside of a bottle mouth in such a way that each external screw is exactly the samé
size; and in order that our invention may be more fully understood we have attached
hereto drawings showing the main principles upon which wo work.
Referring to the drawings the dies D are first mado in one piece as shown at
Figs. 1 and 2, having a thread t formed through them and a hardened plate a secured
underneath, Fig. 1 being a sectional plan and Fig. 2 an end view. The dies D are
then sawn across taking out a piece from each side as shown at Figs. 3 and 4, Fig. 3
being a sectional plan and Fig. 4 an end view.
The separated dies DD are then secured to the ends of the handles H H of the Tools in
the ordinary manner as shown at Figs. 5, 6, and 7, Fig. 5 being a part sectional plan of
the plug end of our improved tools having a straight plug P, and Fig. 6 being an end
view of the same showing the dies D D closed and in working position. Fig. 7 shows
a plug P with an annular projection n which is for the purpose of forming a ledge in
the bottle mouth; this ledge may be of any desired depth.
Although we only show tools having a plain plug P (Fig. 5), and a plug P with a
projection n (Fig. 7) we would have it well understood that our improved dies
may be attached to Tools having various forms of plug, and to Tools for forming
grooves in bottle mouths, of which we purpose showing examples in our complete
specification.
..
To work on the mouth so formed we employ a suitable screw cap, which cap may
either be fitted with a cork lining, or a cork may first be driven into the bottle and the
cap screwed over it. The ledge arrangement shown Fig. 7 is specially applicable'in
combination with our above-named improvements.

We DAN RYLANDS of Hope Glass Works, Stairfoot, near Barnsley, in the County
of York, Glass Bottle Manufacturer, and BENJAMIN STONER, of No. 2, Dearne
Terrace, Stairfoot, aforesaid mechanic 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:—
Our invention relates to tools for forming the mouths of bottles or jars and also in
the means for closing the same.
In carrying out our invention we form by means of suitable tools a screw thread on
the outside of the mouth of bottle or jar the said thread being formed in such a way
that the screws formed by the saine dies are exactly alike in size and shape.
Referring to the drawings left with the Provisional Specification the dies D are
first made in one piece as shown at Figs. 1 and 2 having a thread & formed through
them and a hardened plate a screwed underneath, Fig. 1 being a sectional plan and
Fig. 2 an end elevation. The dies D are then sawn across, thus taking out a piece
from each side D D as shown at Figs. 3 and 4, Fig. 3 being a sectional plan and
Fig. 4 an end view. The separated dies DD are then secured to the ends of the
handles H H of the Tools in the ordinary way as shown at Figs. 5, 6, 7, Fig. 5 being
a part sectional part of the plug end of our improved tools having a straight plug P
and Fig. 6 being an end view of the same showing the dies DD closed and in working
position. Fig. 7. shows a plug P with an annular projection n which is for the
purpose of forming a ledge in the bottle mouth; this ledge may be of any desired
depth.
Our herein-beforo described improved dies D D may be attached to tools having
any suitable form of plug P and they may also bo attached to tools for forming grooves
in bottle mouths, as drawn at Fig. 8 in the drawings hereunto attached such tools
being constructed in the manner shown or in any other suitable way.
Our improved dies D in combination with the tools are worked by the bottle-maker
in the following manner.
After the bottlemaker has placed sufficient molten or viscous glass around the neck
of the bottle or jar he places the plug P figs. 5, 7 & 8 or any other form of plug into the
unformed mouth of bottle or jar, after which he presses to the handles H so causing the
threaded faces of the dies D to press on to the viscous glass. He then works the mouth
up by means of revolving the bottle with a pontil with one hand and grasping the
improved tools with the other. In revolving the bottle the oxterior of the mouth
thereof is threaded backwards and forwards between the dies D D. After a satis-
factory mouth has been thus formed the handles H are released and the dies D spring
apart, when the bottle may be removed from the plug P and taken by the takerin and
placed into the annealing arch.
The tools shown at Fig. 8 work in the following way: The ring of molten viscous

page_text: glass is placed around the neck by the bottle-maker in the usual way; then the plug P
is forced into the unformed mouth, after which the handles H are closed or compressed;
this causes the rods h' together with the levers h³ to open out or turn the halves p'p'
of plug P partially round, so that the cutters p³ come into position for forming groove
in mouth of bottle. The bottle is then revolved and the exterior of the mouth thereof
is threaded backwards and forwards between the dies D D. The cutters p' move
backwards and forwards with the mouth of bottle so that the groove formed thereby
is annular. The stems p' of parts p' of plug are of a square section where they pass
through the levers h2, and the holes in said levers are also correspondingly square.
As the bottle mouth is partially unscrewod from the dies DD the cutters p* with
the parts p of plug P travel with the mouth of bottlo by which means the springs jj
are compressed between the collars nn and lovers h² and when the mouth of bottle is
revolved in the reverse direction and so threaded back between the dies DD the
springs draw back the parts pl and cutters p³ by which means the interior of mouth
of bottle has an annular groove formed therein and the exterior thereof screwed or
threaded. When the said mouth has been satisfactorily formed the handles H are
released and the cutters p³ with parts pl close so that the bottle can be with-drawn from
the tools.
To work on the mouth of the bottle or jar so formed we employ or use a suitable
screw cap C which may be fitted with a cork lining L as shown at Fig. 9, or a cork L
may be first driven into the bottle mouth and the cap C screwed over it as shown at
Fig. 10. In either case a wood disc may be used between the cork L and the cap C.
Fig. 9 is an elevation of bottle mouth showing a section of cap C and cork
lining L, and figure 10. a sectional elevation of bottle neck with section of cap C and
cork L.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is:
1. In the manufacturo of bottles or jars the uso of dies DD constructed and
arranged substantially as described and shown at figs. 1, 2, 3, 4, 5, 6, 7 and 8 or any
mere modification thereof.
2. In connection with bottles or jars constructed with screw mouths in the manner
herein described the combination of a cap C and cork L substantially as described and
shown at figs. 9 and 10, and for the purpose specified.
