I ALBERT JULES THEODORE WILD of 51 Great Dover Street Borough in the
County of Surrey Civil Engineer do hereby declare the nature of my Invention for
AN APPARATUS OR TOOL TO BE USED IN THE MANUFACTURE OF BOTTLE NECKS
to be as follows:-
An improved apparatus or Tool for moulding and finishing Necks of Bottles
which invention comprises all kinds of external threads or Seatings or other
devices for securing Stoppers in Bottle Necks by which instrument great accuracy
is obtained in forming any device external or internal in an expeditious manner.
To carry out my invention I employ a pair of tongs having in their centre a
suitable plunger such as are used in forming necks of Bottles.-The tongs are
provided with revolving dies of the same diameter as the Bottle Neck to be formed,
which dies have a left handed screw thread cut thereon to make a right handed
screw thread on the Bottle Neck and in order that both of the dies shall accurately
revolve and fall in with the thread or other device I use a connecting link formed
on one end with a suitable slot so as to enable the closing and releasing of the
tongs. To form any external seating above the thread I may use revolving rollers
or rings but I prefer stationary dies of the required size and shape above the
Screw Cut Rollers.

An Apparatus or Tool to be Used in the Manufacture of
Bottle Necks.
I ALBERT JULES THEODORE WILD of 51 Great Dover Street Borough in the
County of Surrey Civil Engineer do hereby declare the nature of my invention for
AN APPARATUS OR TOOL TO BE USED IN THE MANUFACTURE OF BOTTLE NECKS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The tool for the formation of bottle necks is in the form of a pair of spring tongs.
It has the usual central plunger, or core to enter the mouth of the neck of the
bottle whilst the glass is in the molten state and during the time that the exterior
of the head or ring is being moulded.
This central core has at its base a disc or swiller plate (such plate I make of an
oblong form with bevilled edges on all 4 sides) and the core is attached by a screw
and nut on to the stem hereinafter referred to. The stem is attached to the
bottom or spring portion of the tongs, and it has a worm or screw thread cut
around its lower end, which lower end passes through a bole cut in the spring end
of the tongs, and is there adjusted into position by means of an inner and an
outer nut.
Each of the two top ends of the tongs (instead of being straight as hitherto)
I form them curved inwardly as shewn in the drawings, and to any degree of a
curve that may be best suited to the particular size or configuration of the bottle
neck to be moulded.
Passing through a circular hole cut through the top end (see drawings) of each
arm of the tongs is a flat headed pin or spindle having a screw worm cut around
its exterior end. This spindle is held in position and adjusted into any suitable
and required position by a nut fitted on to such screw end on each of the outer
surfaces of the arms of the tongs (see drawings). Around this spindle revolves the
screw roller or indenter hereinafter described, such screw rollers having a left
handed inclination so as to produce on the moulded bottle top a right-handed
screw. Such rollers of course having indentations, an inverted screw, or pattern,
or projections proportioned to the worm, screw or device required to be moulded
around the top of the bottle's neck. The rollers are of the same diameter as the
exterior diameter of the head of the bottle. The central core and stem are held in
their central position whilst in use by a slide bar having a hole in its centre through
which the stem passes The two ends of this bar are made round and fit and work
freely in circular holes cut in the sides of the arms of the tongs.
Figure 1 shews a side elevation of the tongs or tool as formed with the rollers
mounted upon pins or spindles at the extremities of its two arins curved inwardly
as described.
Figure 2 is a side view of the screw roller.
AA are the arms of the tongs.
B. B are the flat headed pins or spindles as screwed on the extremities of

page_text: C' is the central core or plunger which enters the mouth of the bottle, and it may
be constructed of a rigid piece of metal or it may be made hollow or in the form of
a split cone.
D is the disc at the base of the core-the edges of the disc and of the flat heads
of the spindles are bevilled as. shewn in the drawings so as when the rollers are..
adjusted by means of the screw and nut (F) and by enlarging or diminishing the
size of the disc D so as to suit the size of the bottle neck being moulded such
bevilled edges of the disc and spindle heads lie evenly together at, the time the
neck is being moulded.
E is the screw roller,
F is the screw and nut at the outer end of the spindle.
G is the moveable bar or slide passing through and working in holes in the two
arms, such slide holding the core and stem in central position whilst at work.
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 application of screw rollers of the form described and as shewn in the
drawings to the moulding of an external screw or thread around the head of a
glass bottle.
2. The formation at a curve or angle of the top ends of the arms of the tongs and
their application as described.
3. By the novelties as described in the foregoing Specification (and claimed in
claims Nos 1 & 2) and wholly or partially in combination) I claim that I have
attained greater expedition facility and accuracy in metal tongs and their use for
the formation of external screws or other patterns upon the exteriors of bottle
heads or necks.
