Improvements in Apparatus for Manufacturing Bottles and other
Hollow Glass Articles,
I, HOWARD MATRAVERS ASHLEY of Ferrybridge in the County of York, Engineer
do hereby declare the nature of this invention to be as follows:-
In previous Specifications I have described apparatus for the manufacture of glass
bottles and similar hollow glass articles, and certain parts and forms of such
apparatus have for sometime been in use operating according to a system which
may be briefly explained as follows: A quantity of molten glass is poured into a
cup shaped mould, termed a parison mould, the lower part of which is made the
counterpart of the shape which the head and neck of the bottle are intended, to
have. While the glass is still in a plastic state in the parison mould, a punch or
plunger is pushed up into the body of the glass and withdrawn, thus forming a
cylindrical cavity in the glass. The parison mould is then inverted and withdrawn
the neck mould or that part which embraces the head and neck being still left in
position so that the parison or bulb of glass remains suspended by the head and neck;
this bulb being still plastic, and tending to elongate itself by gravity, is then enclosed
within a mould which is a counterpart of the finished shape which the bottle is
intended to have. Air or gas under pressure is then admitted into the interior of the
glass bulb through a perforation in the punch or plunger and the glass is thus dis-
tended so as to take the shape of the mould enclosing it.
This mould being then removed, the bottle remains suspended by the head and
neck, and that part of the mould being then opened, the finished bottle is released
and is conveyed away to be-annealed. Each of the moulds employed is necessarily
made in parts which are brought together forming the mould to receive the glass and
are separated in order to release the bottle. It is to the construction of machinery
for operating these moulds in connection with the punch or plunger and air supply
that this invention relates.
The machine which I am about to describe, instead of being arranged for making
one bottle at a time, the various movements being effected in succession by the
operator, is what may be termed a repeating machine, having several sets of apparatus
mounted on a revolving frame, with means of performing automatically the various
movements, so that there are at the same time several bottles in successive stages of
their manufacture, molten glass being supplied to the parison moulds presenting them-
selves successively at one part of the apparatus, and finished bottles being delivered
successively at another part of the apparatus, the manufacturing process being thus
rendered virtually continuous.
In the accompanying drawings shewing a repeating machine arranged with four
sets of bottle making apparatus.

page_text: Referring first to Figs. 1 and 2, from a circular base I extends upwards a column H
to a collar where there is a race for conical antifriction rollers J, above which extends
a vertical shaft K having fixed on its upper part a circular table L. Under the
stationary table L is fitted a revolving table E rigidly connected by a column G to a
lower revolving table F. These tables revolve round the shaft K their weight being
carried on the antifriction rollers J. Within the table E and attached to it is a
toothed rim E with which gears a pinion E on the end of a vertical spindle which
is mounted in an upright bearing projecting above the table L, and is driven by
bevil gear from band pulley M; the table E, is thus caused to revolve in the direction
of the arrow a the driving band being somewhat loose or the gearing being provided
with a friction clutch to allow of the revolution being easily retarded or stopped.
The revolving table E, carries equally spaced round its circumference four moulding
apparatus marked A B, C D, in Fig. 1.
At A. the apparatus rests for a time in condition to receive in its cup or parison
mould m a supply of molten glass forming the parison. In passing from A to B, the
punch or plunger is pushed up and withdrawn, and the parison mould is inverted
and withdrawn. At B. the bottle mould m² is raised and closed around the parison
and the glass is distended by blowing, also the bottle mould m² is opened and lowered.
In passing from B, io C, the bottle is suspended from the neck moulde which is
opened at the place C, allowing the bottle to drop to be removed for annealing.
In passing from C to D, the neck and parison moulds become cooled, and in passing
from D, to A, they are closed ready to receive another charge of glass. Thus, as the
table E, intermittently moves through each quarter of a revolution, the four sets of
single apparatus pass each in its turn through the four conditions of operation
above described.
P
During the successive step by step movements of the table E, the several parts of
the casting and blowing apparatus are worked automatically in the following manner.
The punch or plunger ? is pressed back by a spring so that when the apparatus is at A
it is in the position shewn in Figs. 3, 4, and 6, the upper end of the punch p
forming in that case the bottom of the parison mould minto which a charge of melted
glass is poured. As the apparatus moves from A to B carrying with it a vertically
sliding rod P, which is immediately under the punch p, this rod which has a roller
at its lower end in passing along an adjustable incline Q, (Fig. 2) fixed on the base I
of the machine, is caused to rise pushing up the punch p into the plastic glass in m.
When descends the hinder incline q', is again pressed down by its spring leaving
a cavity in the glass contained in the parison mould m. During the farther part of
the motion from A to B, the apparatus is inverted, so as to take the position shewn in
Figs. S and 9 and at the same time the two halves of the parison mould mare with-
drawn. For this purpose, a friction wheel fixed on the axis of the crank arm
passes under a segment 2 (Fig. 1) fixed on the underside of the stationary table 1,
and is thus causeil to make half a revolution thereby inverting the arm 7 and the
parison mould and parts carried by it. In order to ensure the turning of the wheel w
through exactly half a revolution and to hold it when turned, the wheel . as shewn
in Fig. 7, is made with two opposite notches to be engaged by a spring pawl having
a tail that travels immediately under the lower face of the table L. Just before
the wheel comes to the segment pl which is to turn it, the tail d' passes under an
incline 2 (Fig. 7), whereby the pawl is withdrawn from the notch of we in which it
was engaged, and thereafter, when the wheel is turned half round in travelling
along the segment, the pawl falls into the other notch of and holds it. By this
turning of the axis a not only is the arm i inverted, but also the two halves of the
parison mould mare withdrawn. These halves are attached to slides e² (Fig. 3) each
attached by a pin to a segment 2 (Fig. 5) which is engaged in an eccentric groove
formed in the face of a disc d attached to the table E. As the arm ? makes its half
revolution carrying round with it the slides and their attached segments 2, these
segments in travelling from the inner portions of the eccentric grooves in d to the
outer portions of these grooves are moved outward from the centre thus separating
the two halves me of the parison mould as shewn in Figs. S and 10. The finishing of

page_text: the bottle is effected at the position B by means of the apparatus shewn in Figs. 12
and 13. The two sides m² of the bottle mould are jointed to a table which is raised
by depressing a treadle f, and then by raising a lever having arms linked to the two
half moulds m² these are closed together enclosing within them the glass bulb which
was left suspended by its neck in the neck mould when the parison half moulds m
were withdrawn. The bottle then being blown, the lever is depressed withdrawing
the half moulds m², the treadle f is released, allowing the table to descend; and the
'finished bottle is left hanging by its neck ready to pass on to the next position C.
For effecting the blowing of the bottle, compressed air or gas is supplied by a pipe $
(Fig. 2) to the central bore of the stationary shaft K, and by lateral holes the air
passes into the recess of the central boss of the table E, which boss is provided with
stuffing boxes U, to prevent escape. From the recess, air pipes extend one to
each of the axes a, connected thereto by a stuffing box s. From the bore of the
axis a passage extends along the crank arm and communicates by a flexible hose
or pipe with the bore of the punch . Each of the air pipes has a regulating cock
or valve V, which is generally nearly closed, allowing only a small passage of air, but
when the blowing fakes place as described with reference to Fig. 12, the cock or
valve V is sufficiently opened by means of a hand lever X, to give the supply of air
necessary for blowing. When the blowing is effected the lever X, being released is
retracted by a spring. It has been already mentioned that the movement of the table E,
and of the four sets of apparatus carried by it is intermittent, it must rest while one
parison mould is receiving glass at A, and while at the same time a bottle is being
blown at B. This stoppage is effected by the operator moving the spring handle 63
(Figs. 1 and 2) of a brake lever which is pivotted in the table L and has a lower arm
that can be brought to bear against internal protuberances from the rim of the
table E. When the blowing is completed and the bottle mould opened and lowered,
the handle 63 is released and the table E, continues its revolution carrying with it the
blown bottle which is still suspended from the closed neck mould c. This neck mould
is made in halves each attached to a slide. The two slides are linked to a bent
lever on opposite sides of its fulcrum Figs. 8 and 10. As this lever of advances
towards the position C, its bent end passes under a segment p² which is fixed above
the table L. The lever o2 is thus moved to one side as shewn in Fig. 10 withdrawing
the two halves. c of the neck mould and so releasing the bottle which can now be
removed. When o² passes clear of 72 the neck moulds are closed' together by a spring.
As the apparatus passes on from C to D and then from D to A time is given for the
cooling of the neck and parison moulds, also the apparatus is reinverted and the
parison mould closed at the position D, by another set of the detent incline and
the friction segment pacting on the wheel in. Thus when the apparatus reaches A
it is ready for a fresh, operation as described. Fig. 1 is a plan and Fig. 2* is a part
elevation of the base of the machine shewing a modified arrangement for working
ach of the punches p, which in this case have no springs to retract them. A grooved
incline Q is fixed adjustably in height having its groove in the path of a roller
mounted on the end of a lever P2 which is pivotted on a bracket P³ projecting down
from the revolving disc F. The other end of the lever P2 has a mouth m³ which
engages a collar at the lower end of the punch p. As the disc F turns carrying with
it the lever P, this lever as its roller passes along the groove of Q2 is caused
to make an oscillation first pushing up and then drawing down the punch or
plunger 2.
Instead of employing compressed air to distend the glass in the finishing mould,
the pressure of the atmosphere may be used for this purpose, by admitting air into
the interior of the plastic glass bulb while the bulb itself is enclosed in a casing which
is vacuous or nearly so, so that the glass is distended by the excess of the internal
above the external pressure.
In order to adapt the finishing part of the apparatus to act in this manner it is
modified as shown in Fig. 14 which is a vertical section and in Fig. 15 which is a
plan on line 3.3 Fig. 14. The column h³ which is tubular communicates at its base

mouth of which is conical, the base of the finishing mould having jointed to it the
two halves forming the sides m is supported on a grooved stem which can slide in
the vertical limb of the elbow p' and partially by light springs e projecting inside
the vase .
On raising the vase its conical mouth acting on the inclined sides m² of the mould
closes them together and at the same time makes a sufficiently tight joint with the
flanges. There being now a partial vacuum within the vase while air is free to
enter through the hollow puuch into the interior of the glass bulb or parison, this
becomes distended so as to fit the mould m².
On now lowering the vase the two half moulds m² fall by gravity into their
inclined position leaving the finished bottle suspended from the neck mould in the
same condition as if it had been blown by compressed air instead of by exhaust. The
vacuum pipe may be provided with a valve worked by a hand lever.
'
Throughout the description, bottles are spoken of as being the articles manufactured
by the machinery described, but it is to be understood that many other hollow articles
of glass, such as jars or other vessels having blown bodies and heads beaded or
otherwise lipped, can be manufactured in a similar way by merely adapting the moulds
and plungers to their forms. Air under pressure is also spoken of as being the
Huid employed for blowing, but obviously other gases might be used in liko
manner.

I, HOWARD MATRAVERS ASHLEY of Ferrybridge in the County of York Engineer
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:
In previous Specifications I have described apparatus for the manufacture of glass

under pressure is then admitted into the interior of the glass bulb through a per-
foration in the punch or plunger and the glass is thus distended so as to take the
shape
of the mould enclosing it. This mould being then removed, the bottle remains
suspended by the head and neck, and that part of the mould being then opened, the
finished bottle is released and is conveyed away to be annealed. Each of the

page_text: moulds employed is necessarily made in parts which are brought together forming
the mould to receive the glass and are separated in order to release the bottle. It is
to the construction of machinery for operating these moulds in connection with, the
punch or plunger and air supply that this Invention relates.
The machine which I am about to describe instead of being arranged for making
one bottle at a time, the various movements being effected in succession by the
operator, is what may be termed a repeating machine having several sets of apparatus
mounted on a revolving frame, with means of performing automatically the various
movements, so that there are at the same time several bottles in successive stages of

shewing the finishing mould apparatus.
Referring first to Figures 1 and 2, from a circular base I extends upwards fa
column H to a collar-where there is a race for conical antifriction rollers J, above
which extends a vertical shaft K having fixed on its upper part a circular table L.
Under the stationary table L is fitted a revolving table E rigidly connected by a
column G to a lower revolving table F. These tables revolve round the shaft-K
their weight being carried on the antifriction rollers J. Within the table E and
attached to it is a toothed rim El with which gears a pinion E2 on the end of a
vertical spindle which is mounted in an upright bearing E3 projecting above the
table L, and is driven by bevil gear from band pulley M; the table E, is thus caused
to revolve in the direction of the arrow a', the driving band being somewhat loose
or the gearing being provided with a friction clutch to allow of the revolution being
easily retarded or stopped. The revolving table E, carries equally spaced round
its circumference four moulding apparatus, marked respectively A. B. C. D. in
Figure 1.
At A the apparatus rests for a time in condition to receive in its cup or parison
mould a supply of molten glass forming the parison. In passing from A to B.
the punch or plunger p is pushed up and withdrawn, and the parison mould m is
inverted and withdrawn. At B, the bottle mould m² is raised and closed around the
parison and the glass is distended by blowing, also the bottle mould m is opened and
fowered. In passing from B, to C, the bottle is suspended from the neck mould,
which is opened at the place C, allowing the bottle to drop, to be removed for
annealing.
In passing from C, to D, the neck and parison moulds become cooled, and in
passing from D, to A, they are closed ready to receive another charge of glass.
Thus, as the table E, intermittently moves through each quarter of a revolution, the
four sets of single apparatus pass, each in its turn, through the four conditions of
operation above described. During the successive step by step movements of the
table E, the several parts of the casting and blowing apparatus are worked auto-
matically in the following manner. The punch or plunger pis pressed back by a

page_text: By this
spring so that when the apparatus is at A, it is in the position shewn in Figures 3. +
and 6, the upper end of the punch forming in that case the bottom of the parison
'mould into which a charge of melted glass is poured. As the apparatus moves
from A to B, carrying with it a vertically sliding rod P, which is immediately
under the punch p, this rod which has a roller. r. at its lower end in passing along
an adjustable ineline Q. (Figure 2) fixed on the base I of the machine, is caused to
rise pushing up the punch p into the plastic glass in m. When descends the
hinder incline 4, p is again pressed down by its spring, leaving a cavity in the glass
contained in the parison mould m. During the farther part of the motion from A,
to B, the apparatus is inverted, so as to take the position shewn in Figures 8 and 9 and
at the same time the two halves of the parison mould on are withdrawn. For this
purpose friction wheel a fixed on the axis of the crank arm passes under a
segment (Figure 1) fixed on the under side of the stationary table L, and is thus
'caused to make half a revolution thereby inverting the arm and the parison mould
and parts: carried by it. In order to ensure the turning of the wheel through
exactly half girevolution and to hold it when turned, the wheel cas shewn in
Figure 7 is made with two opposite notches to be engaged by a spring pawl having
a tail that travels immediately under the lower face of the table L. Just before
the wheel te comes to the segment which is to turn it, the tail passes under an
incline p (Figure 7) whereby the pawl is withdrawn from the notch of win which
it was engaged, and thereafter, when the wheel is turned half round in travelling
along the segment pl the pawl falls into the other notch of and holds it.
turning of the axis not only is the arm inverted, but also the two halves of the
parison mould mare withdrawn. These halves are attached to slides (Figure 3)
each attached by a pin to a segment (Figure 5) which is engaged in an eccentric

groove formed in the face of a disc d attached to the table E:
its half revolution carrying round with it the slides and their attached segments,
these segments in travelling from the inner portions of the eccentric grooves in d to
the outer portions of these grooves are moved outwards from the centre thus separat-
ing the two halves m of the parison mould as shewn in Figures 8 and 10. The
finishing of the bottle is effected at the position B by means of the apparatus shewn
in Figures 12 and 13. The two sides me of the bottle mould are jointed to a table t²-
which is raised, by depressing a treadle f and then, by raising a lever having arms
linked to the two half moulds me, these are closed together enclosing within them the
glass bulb which was left suspended by its neck in the neck moulde when the parison
half moulds m were withdrawn. The bottle then being blown, the lever his
depressed withdrawing the half moulds m², the treadle is released allowing.the
table to descend, the finished bottle is left hanging by its neck ready to pass on to
the next position C. For effecting the blowing of the bottle, compressed air or gas is
supplied by a pipe S (Figure 2) to the central bore of the stationary shaft K, and by
lateral holes the air passes into the recess of the central boss of the table E, which
boss is provided with stuffing boxes U, to prevent escape. From the recess, air
pipes extend one to each of the axes a connected thereto by a stuffing box 8. From
the bore of the axis a a passage extends along the crank arm i and communicates by
a flexible pipe or hose with the bore of. the punch p. Each of the air pipes has a
regulating cock or valve V which is generally nearly closed, allowing only a small
passage of air, but when the blowing takes place as described with reference to
Figure 2, the cock or valve V is sufficiently opened by means of a hand lever X, to
give the supply of air necessary for blowing. When the blowing is effected, the
lever X, being released is retracted by a spring. It has been already mentioned
that the movement of the table E, and of the four sets of apparatus carried by it is
intermittent, it must rest while one parison mould is receiving glass at A., and while
at the same time a bottle is being blown at B. This stoppage is effected by the
operator moving the spring handle 63 (Figures 1 and 2) of a brake lever which is
pivotted in the table L and has, a lower arm that can be brought to bear against
internal protuberances from the rim of the table E. When the blowing is com-
pleted and the bottle mould opened and lowered, the handle 3 is released and the

page_text: table E, continues its revolution carrying with it the blown bottle which is still sus-
pended from the closed neck mould c This neck mould is made in halves each
attached to a slide s¹. The two slides are linked to a bent lever of on opposite
sides of its fulcrum (Figures S. and 10). As this lever advances towards the
position C. its bent end passes under a segment 2 which is fixed above the table L.
The lever is thus moved to one side as shewn in Figure 10, withdrawing the two
halves e of the neck mould and so releasing the bottle which can now be removed.
When 2 passes clear of the neck moulds are closed together by a spring. As the
apparatus passes on from C, to D, and then from D to A. time is given for the cooling
of the neck and parison moulds, also the apparatus is resinverted and the parison
mould closed at the position D, by another set of the detent incline p and the friction
segment acting on the wheel. Thus when the apparatus reaches A. it is ready
for a fresh operation as described.
Figure 1 is a plan and Figure 2* is a part elevation of the base of the machine
shewing a modified arrangement for working each of the punches p, which in this
case have no springs to retract them. A grooved incline Q2 is fixed adjustably in
height having its groove in the path of a roller mounted on the end of a lever på
which is pivotted on a bracket P projecting down from the revolving disc F. The
other end of the lever 12 has a mouth m³ which engages a collar at the lower end
of the punch p. As the disc F turns, carrying with it the lever P, this lever as its
roller passes along the groove of Q2 is caused to make an oscillation first pushing up
and then drawing down the punch or plunger p..
Instead of employing compressed air to distend the glass in the finishing mould, the
pressure of the atmosphere may be used for this purpose by admitting air into the
interior of the plastic glass bulb, while the bulb itself is enclosed in a casing which is
vacuous or nearly so, so that the glass is distended by the excess of the internal above
the external pressure.
In order to adapt the finishing part of the apparatus to act in this m
this manner, it-is-
modified as shewn in Figure-14 which is-a-vertical-section and in Figure 15 which is
a plan on line 3-3 Figure 14. The column 3 which is tubular communicates at its
base by a pipe with a vacuum chamber exhausted by a pump or otherwise and has
at its top an elbow pipe 2 on which is fitted to slide vertically a vase provided
with a stuffing box. On depressing the treadle f this vase (which with its attach-
ments is counterbalanced by a weight ) is raised until its upper lip is pressed up
against flanges projecting from the two halves of the neck mould. Within the
vase the mouth of which is conical, the base of the finishing mould having jointed
to it the two halves forming the sides "m² is supported on a grooved stem which can
slide in the vertical limb of the elbow and partially by light springs e projecting
inside the vase e.
Quraising the vase its conical mouth acting on the incline sides m² of the
mould closes them together and at the same time makes a sufficiently tight joint with
the flanges. There being now a partial vacuum within the vase while air is free
to enter through the hollow punch into the interior of the glass bulb or parison, this
becomes distended so as to fit the mould m².
On now lowering the vase the two half moulds m² fall by gravity into their
inclined position leaving the finished bottle suspended from the neck mould in the
same condition as if it had been blown by compressed air instead of by exhaust. The
vacuum pipe may be provided with a valve worked by a hand lever.
Throughout the description, bottles are spoken of as being the articles manu-
factured by the machinery described, but it is to be understood that many other
hollow articles of glass, such as jars or other vessels having blown bodies and heads
beaded or otherwise lipped, can be manufactured in a similar way by merely adapting
the moulds and plungers to their form. Air under pressure is also spoken of as
being the fluid employed for blowing, but obviously other gases might be used in like
Juanner.
