of Tools or Apparatus Used in such Manufacture.
I THOMAS ETHERIDGE HARPER of Pilgrim House, South Weald in the County of
Essex, Gentleman do hereby declare the nature of this invention to be as follows:-
:-
The first part of such Invention consists in forming upon the exterior of the necks
of Bottles, Grooves threads or sockets for the purpose of catching and retaining the
stopper, such Grooves threads or sockets are intended to catch and retain the stopper
and to allow the same to be readily fixed and detached. Hitherto Grooves threads
and sockets have been generally formed in the interior of the Bottle because of the
difficulty experienced in forming them on the exterior otherwise than by moulding
which method is often objectionable on account of its causing corresponding impres-
sions in the interior of the neck and mouth and thereby impeding the formation of a
water and air tight joint and for other reasons. I therefore propose to use for the
purpose a specially constructed tool or apparatus which forms the second part of my
invention and comprises a pair of spring tongs with a central stem or rod terminating
in a plug or plunger similar to those employed in making the ordinary Bottle necks
but in addition to the dies attached to the upper ends of such tongs for shaping the
exterior of the neck and mouth of the Bottle I propose to use a second but smaller
pair of tongs or arms suitably shaped at their upper extremities and working upon a
revolving pivot attached to the central stem or rod and so constructed that as pressure
is applied to the spring tongs the upper parts of the second tongs or arms close with
the dies and are forced into the plastic glass outside the Bottle neck and form the.
Groove thread or socket desired and remain embedded in the Grooves or sockets so
formed whilst the Bottle neck is worked round between the outer dies in the usual
way and are withdrawn as the tongs open which can be done either by the action of
the outer springs operating by means of a "Cam" or independly..

of Tools or Apparatus Used in such Manufacture.
I, THOMAS ETHERIDGE HARPER of Pilgrim House, South Weald in the County of
Essex, Gentleman, 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 this invention is to form grooves. or recesses on the exterior of the
necks of bottles for the purpose of catching and retaining the stopper by what is
known as a bayonet joint attachment.
I propose to use for the purpose a tool or apparatus composed of a pair of spring
tongs with a central stem or rod terminating in a plug or plunger similar to those
employed in making the ordinary bottle necks but in addition to the dies attached to
the upper ends of such tongs for shaping the exterior of the neck and mouth of the
bottle I propose to use a second but smaller pair of tongs or arms suitably shaped at
their upper extremities and working upon a revolving pivot attached to the central
stem or rod and so constructed that as pressure is applied to the spring tongs the
upper parts of the second tongs or arms close with the dies and are forced into
the plastic glass outside the bottle neck and form the groove thread or socket desired
and remain embedded in the grooves or sockets so formed whilst the bottle neck is
worked round between the outer dies in the usual way and are withdrawn as the tongs
open which can be done either by the action of the outer springs operating by means
of a cam or independently.

The drawings annexed shew examples of tools formed as above described.
Figures 1 to 6 shew various views of one form of the tool and figures
shew views of the head of a bottle formed by this tool. Figures 9 and 10 shew a
modification of the tool and Figure 11 shews the head of a bottle formed by it.
Figure 1 is a side view of the tool.
Figure 2 is an elevation partly in section of a part of the central stem and the parts
carried thereby but without the tongs.
Figure 3 is another elevation of the same parts.
Figure 4 is an end elevation of some of the parts.
Figure 5 is a section on the line 1-1 of Figure 1.
Figure
6 is an end view of one of the jaws.
Figure 7 is an elevation of the bottle neck.
Figure 8 is a section on the line 2-2 in Figure 7.
Figure 9 is a side view of the modified form of tool when open-and Figure 10 is
a side view of the same tool when closed. Figure 11 shews a side view of the head of
a bottle formed by the tool.
In figures 1 to 8 a a are the limbs of the spring tongs, b b the jaws they carry, c is
the stem and d is the plug. The plug is in two parts, one part d is fixed to the stem
and the other part d' can turn around it and is provided with the flange d¹×. These

page_text: parts constitute the ordinary necking tool, the parts which I have added are the ring e,
the levers ff, and the slider g. The ring e is able to turn on the stem between a
collar cand the screw nut h. The levers ff are jointed to the ring at f¹f and they
are also held but so as to be able to move radially in notches in d in the flange d¹.
The ends ff of the levers are of the form of the indentations which it is desired to
produce in the sides of the neck of the bottle. The slider g on the stem c carries the
ring g' which embraces the levers f; in the position shewn in the drawing the ring
holds the levers in such a position that the neck of the bottle can enter between them
as the plug d is inserted into the mouth as far as the flange d¹x will admit. The ring
however can be made to advance nearly up to the flange and the operating on the
levers on the other side of their fulcra it closes them together and the glass of
the neck becomes indented by their ends. 92 are arms on the slides and g²x g2x
are slots in these arms which receive studs a' a' fixed into the limbs a. By the
operation of these studs on the slider the levers fand jaws bare caused to operate in
unison as already described.
In Figures 7 and 8 the indentations produced in the neck by the levers are shewn.
h is the part parallel to the axis of the bottle and is the circumferential part of the
recess.
In the modification shewn at figures 9 and 10 the levers fin place of being acted
upon by a ring g' are coupled by links to a slide g' which moves to and fro with the
slider g and can also turn freely around the central stem c.
The inner surfaces of the jaws b are also so shaped as to form a continuous groove
around the exterior of the head of a bottle into which pass the longitudinally
formed grooves that are made by the ends f2 of the levers f, so that the ends f2 of
the levers need have no right angled bend formed in them as in figures 1 to 6. The
head of a bottle so formed with a continuous groove around its exterior and longitu-
dinally formed grooves passing from it to the extremity of the head is shewn at
Figure 11.
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 forming indentations in the heads of bottles with
a revolving swiller plate dx and levers or instruments f projecting through this plate
and free to be carried round with it and mechanism for moving the ends f² of the
parts finwards towards the central plug when the tongs are closed.
2. The construction of tools for forming indentations in the heads of bottles
substantially as herein before described and illustrated at Figures 1 to 6.
3. The construction of tools for forming indentations in the heads of bottles
substantially as herein before described and illustrated at Figures 9 and 10.
4. A glass bottle with a continuous groove formed around the exterior of its head
and with longitudinal grooves passing from this groove to the end of the head
substantially as described and illustrated at Figure 11.
5. A glass bottle with L shaped grooves or recesses formed on opposite sides of the
exterior of its head substantially as described and illustrated at Figures 7 and 8.
