COMPLETE SPECIFICATION.
Improvements in Apparatus for Forming the Mouthpiece of Glass
Vessels, Bottles, Jars, and the like to Receive Specially Shaped
Stoppers.
We, FRIEDRICH ERNST WILLIAM HIMLY, Manufacturer and CARL AUGUST
ALDAG, Mechanician both of Nienburg on the Weser, Germany 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 :-
This invention relates to an improved apparatus for forming the mouths of glass
bottles, jars and the like, adapted to be closed by stoppers having projections at
their lower ends which engage with corresponding shoulders formed inside the
necks of the bottles or the like. The said apparatus consists in a tool provided
with spring arms forming tongs ending in rotatable jaws for forming or shaping
the exterior of the neck of the bottle and having a flattened conical mandril
capable of being inserted into the mouth or neck of the bottle the base or rear end
of such mandril being provided with a rotative die shaped to mould the required
internal form of the mouth. This die is held or retained in position and prevented
from rotating relatively to the mandril by a spring catch which is released by the
motion of the spring arms of the tongs when they are forced together, and enables
the die to revolve with the bottle, whilst the mandril itself is held stationary or
rotated relatively to the bottle in order to form the shoulders or projections in the
interior of the neck of the bottle as hereinafter explained.
And in order that our said invention may be fully understood we shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 of the accompanying drawings represents in elevation a tool cr
apparatus for moulding the mouths of bottles according to this invention the parts
being in the position which they occupy when the tool is not in use.

page_text: Figure 2 represents the tool partly in longitudinal section shewing the position of
the parts when the instrument is acting upon the bottle.
Figure 3 represents the tool in end elevation.
Figure 4 illustrates in end and side elevation (the latter being partly in section)
a detail of the parts employed for moulding or shaping the interior of the mouth of
the bottle as hereinafter explained.
Figures 5 and 6 illustrate the tool in transverse sections taken on the lines 5—5
and 6-6 Figure 1 respectively.
Figure 7 represents in vertical section and in plan the mouth of a bottle as
formed by the action of the improved tool or apparatus.
Figure 8 represents in vertical section and in side elevation a specially shaped
stopper employed in combination with bottles having mouths formed by means of
this improved tool or apparatus.
As represented in Figures 1 to 4 of the drawings the tool or apparatus is
constructed in the form of spring tongs S provided with a pair of jaws carrying
rollers of suitable shape for forming or moulding the exterior of the neck or
mouth of the bottle.
b
A mandril a is rigidly attached by a rod b to the bow of these tongs.
This mandril is of taper or conical form being flattened on two sides as
represented in the end views Figures 3 and 4 and is connected to its support 6 by a
cylindrical or round part a' forming an axis or spindle upon which a die f¹ƒ³ is
capable of rotating. The front end f¹ of this die is of the same shape and
dimensions in transverse section as the mandril a and forms a continuation of the
latter but the other end 2 is of circular or cylindrical form of different diameters
forming steps corresponding to the shape of the shoulders and recesses to be formed
in the mouth of the bottle for the reception of the stopper and a washer or packing
ring.
It is necessary to provide means for rigidly connecting together the mandril a
and the die f¹ƒ in a position in which the flattened front part 1 of the die
coincides accurately with the mandril and forms a continuation of the latter
presenting a practically unbroken surface so as to enable the die and mandril to
enter and be withdrawn from the elongated opening which they form in the soft.
glass which is placed on the neck of the bottle in the usual manner to form the
mouth. With this object the enlarged end 2 of the die is provided with two
notches on opposite sides (Figure 3) one or the other of which, when the flat
sides of the mandril are in a line with the corresponding sides of the die, coincides
with a notch s in a plate s attached to the rod band forming a guide for the legs
of the tongs S.
A lever c is pivoted at 61 on the central rod b and is acted on at the extremity c¹
by a spring d (Figure 8) which tends to force the opposite extremity into
engagement with the two notches f³ and s¹ herein before referred to as being formed
in the die ff and in the fixed guide plates respectively. To one leg of the
tongs S is attached an inclined arm or plate e (Figures and 6) which acts upon
the end of the lever and when the legs of the tongs S are pressed together
forces this lever out of the notch in the die f₁f so as to release the latter and
render it free to rotate upon the rod or spindle a' attached to the mandril a.
The manipulation and action of the apparatus is as follows:-
Whilst the tongs are in the position represented in Figure 1 in which the die
and mandril are connected together by means of the lever c the mandril and
die are inserted into the mouth of the bottle and the two legs of the tongs are
then pressed together as represented in Figure 2 whereby the connection between
the die and mandril is automatically caused to cease by the action of the arm e the
mandril which is rigidly attached to the tongs being capable of rotating with the
latter and independently of the die f¹ƒ which remains stationary relatively to
the bottle.
The workman holding the tongs in one hand and the bottle or the like in the
other now causes them to rotate relatively to one another so that the mandril forms

page_text: a circular recess or enlargement underneath or at the back of the part containing
the end f¹ of the die which rotates with or remains in one position relatively to the
bottle. This relative displacement of the mandril and die has the effect of leaving
ledges or ribs of glass projecting on each side of the interior of the mouth as
indicated at (Figure 7) forming between them an elongated opening or slot g
underneath or at the back of which a circular passage is formed by the rotation of
the mandril. To remove the tool from the bottle the tongs are placed in a position
in which the flat sides of the mandril coincide with the flat sides of the part f¹ of
the die and the notch f³ in the die coincides with the notch s' in the guide plate.
The legs of the tongs are then released so as to spring apart thereby locking the
die to the mandril by the automatic action of the lever c when released from the
arm e.
g
A stopper employed for closing the mouths of bottles or the like formed as
herein before described is illustrated in Figure 8. The said stopper h may be
composed of glass, porcelain, indurated rubber or other suitable material or
composition and is provided at its lower extremity with projections / corresponding
in length and breadth with the slot or orifice g formed in the mouth of the bottle
by the insertion of the mandril a and flattened part 1 of the die ff. These
projections on the stopper are provided with inclined surfaces h³ which engage with
the under or inner surfaces of the ledges or shoulders x on each side of the orifice
in the bottle. The upper end of the stopper forms a head h underneath which is
placed a washer or packing ring h² of rubber or like material which fits into a
recess formed by the die f' in the mouth of the bottle and prevents leakage.
projecting part of the stopper is provided with a nick as indicated in the section
(Figure 8) or is otherwise arranged to admit of the application of a screw driver
or other instrument which may be necessary after the bottle has remained closed
for a considerable period in order to rotate the stopper and disengage it from the
the mouth of the bottle.
The
The advantages presented by the bottles or the like provided with a mouth
formed by means of the apparatus herein before described are chiefly that whilst
no metallic parts liable to rust are employed the outside of the mouth of the
bottle is enabled to be made perfectly plain or without projecting parts and the
rubber washer being confined or prevented from expanding in any direction a
perfectly tight joint is enabled to be made by rotating the stopper through a
relatively small angle.
Having now particularly described and ascertained the nature of our said inveu-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. An apparatus for forming a slot or elongated opening in the mouth pieces of
bottles and other like vessels provided with a mandril (a) rigidly attached to a
pair of spring arms or tongs (S) and connected with a revoluble die (f¹ f2) and
means for securing the said die in a position coinciding with that of the said
mandril substantially as and for the purpose hereinbefore described.
2. The arrangements and combinations of parts constituting apparatus for
forming the mouth pieces of bottles and other like receptacles substantially as
hereinbefore described.
