Improvements in Machines for Making Bottles.
We DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer, and CHARLES EMMET, of 194 Doncaster Road,
in Barnsley aforesaid, Mechanical Engineer do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in automatically operating the various parts
pertaining to the bottle or jar making machine for which Letters Patent were granted
to James Richard Windmill and numbered 8526 A.D. 1886, in such a manner that
after the molten metal has been by hand or otherwise placed in the mould, the machine
will then perforin the various operations necessary for the production, completion, and
delivery of the bottle or article required, and we carry out our invention in the
following manner.
A suitable number of moulds are arranged around the outer upper surface of a
circular table capable of an intermittent revolving movement around a vertical central
fixed pillar, the revolving movement being effected by ratchet wheel attached by sleeve
to the underside of inould table. This ratchet wheel is actuated by crank, connecting
rod, and pawl, and driven by frictional cone gearing in such a manner that after the
crank has made one complete revolution and rotated the mould table the desired
distance, a spring detent will become engaged in a notch provided for it on the rim
of a disc wheel carried by crank shaft, at the same time breaking contact between the
frictional driving surfaces thus stopping further movement of the crank. To still
further secure the mould table by momentum from overrunning itself, a second spring
detent is provided capable of engaging with notches cut in an annular rim formed on
underside of mould table.
Each of the moulds carried by the mould table are compound, and consist of a
sliding cylindrical pressing mould having a cavity formed on its upper surface and
working in a tubular guide attached by flange to undersurface of mould table. This
pressing mould has an up and down movement given to it by means of antifriction
runners or bowls running on the upper surface of a fixed annular roadway formed
with ascending and descending inclined planes on portions of its circumference, the
other portions being level. Central with and above the tubular guide and pressing
mould, the mould table carries the blowing mould wnich is built up in two sections,
the lower part constituting the body portion, and the upper the neck and part of
the mouth portion, the upper section being in two parts and hinged. Carried by
and hinged to the body mould is a cover by which the compound mould is closed, and
which is formed to produce the remaining mouth portion; this cover is opened and
closed after the manner of a box lid by bowls working on circular inclines and
depressions carried by a disc attached to and surrounding central pillar. Through the
above-mentioned cover, a water-cooled pressing plunger for operating upon the molten
inetal in the pressing mould is free to work, and has intermittent reciprocating motion
given to it by means of an hydraulic piston and rod, the cylinder containing such
piston being supported by a bracket carried by the central pillar. A portion of the
lower part of the body mould is cut away for the entrance and withdrawal of an arm
forming part of a bell-cranked lever having movement in a horizontal direction
given to it by a runner or bowl carried by one of the limbs of the bell-cranked
lever working in a fixed cam secured to and surrounding central pillar. The other
end of the bell-cranked lever is partly circular in plan view and enlarged to fit the
bore of the blowing mould, and has a hole formed through it centrally for the
reception of the smaller diameter of a disc that is turned circumferentially to two
diameters, the larger diameter resting on the upper surface of lever, the upper

page_text: surface of the disc being formned to the configuration of the bottle or jar to be
produced.
A blowing cylinder also carried by bracket from central pillar and fitted with
piston and rod and having constant pressure exercised on its smailer and under area
(as is also the case with the pressing piston) has its lower end fitted with a washer
of jointing material, such as asbestos, and is furnished with an arrangement of
automatic blowing valve referred to hereafter.
The valves operating the pressing and blowing cylinders are actuated by cams
carried by a master shaft suitably situated and timed to make one revolution in
the time required for the various operations requisite in the making of the bottle,
after which operations have been performed the shaft with its cams is stopped by
detent, and will remain so till the detent is again withdrawn for the next series
of operations.
The blowing plunger has attached to it a blowing valve casing containing a
valve the stem of which works through a gland formed on the cover of casing.
The end of a spindle carries a weight ensuring the valve being kept closed and
tight on its seating till the descending blowing plunger causes the valve spindle to
be arrested and stopped in its course by the end of a counterweighted horizontal
lever the counterweighted end of which rests on a fixed stop. The plunger and
valve casing continuing to descend cause the valve seating to leave the suspended
and arrested valve,, allowing air under pressure to pass and enter a port communi-
cating with the interior of bottle to be blown,
The action of the above described machine is as follows:-Any convenient number
of moulds may be used, but for clearness in the description we will follow the move-
ments of one mould and its accessories through the various operations required
during the making of a bottle or jar.
One of the sliding pressing moulds having by rotation of the mould table arrived
at the ladling or charging position, and through action of the annular inclined plane
and runner having reached the charging level in the interior of blowing mould,
and the upper portion of mould being shut, molten metal is now charged into the
cavity contained by the pressing mould; after which the mould cover by still further
rotations of the table and the action of the runner and inclined plane is caused to
close the mould; by the time this has been done the closed mould will have arrived
at the pressing position under the pressing plunger. The plunger descending forces
the molten metal into the space bounded internally by the plunger and externally by
the pressing and mouth portions of the mould, completing the formation of the neck
and mouth of the jar. The mould table being again caused to rotate will, by reason
of fixed inclined plane and runner, lower the pressing mould into its lowest position,
leaving the partly formed bottle suspended by its mouth in the interior of blowing
mould. The sliding pressing mould being now out of the way, the bell-cranked
lever carrying the mould bottom and operated by the fixed cain and runner is free
to enter through the side opening formed in the botton portion of blowing mould.
The mould table still continuing its movement again elevates the sliding pressing
mould, which in its turn lifts the mould bottom carried by the bell-cranked lever
to a sufficient height to enter and close the bottom of the blowing mould. By the
time this has been accomplished, the mould with its partly formed bottle will have
arrived in position under the blowing plunger, which descending makes an airtight
joint with the cover portion of mould; the blowing valve having been opened as
previously described, air under pressure is free to enter the interior of the partly
formed bottle, expanding and causing it to fill and fit the interior of the blowing
nould. The blowing plunger now ascending, and the inould table again being
put into motion, will result in the mould cover rising and uncovering the mould,
in the neck portion of the mould opening, in the descent of the pressing mould
to its lowest position, in the withdrawal of the movable mould bottom, and in the
further ascent of the pressing mould to the delivering position carrying with it
and elevating the finished bottle till it is above and clear of the upper surface of
the mouth mould. Then by action of a pusher arm worked by blowing plunger the

page_text: bottle is carried from the ring-like upper surface of the blowing mould on to the
table of a counterweighted tippler, on reaching which the weight of the bottle being
greater than the balance weight will cause the bottle to be turned from the vertical
to a horizontal position, when it will by gravity roll on to the casher or delivery
plate, and from thence by hand to the annealing ovens.
It will be seen that the whole of the above-described operations, constituting
charging, pressing, blowing, and delivery of the bottle, are going on at one and
the same time, and with the exception of charging the mould all the operations
take place automatically; and it will also be understood that every time the mould
table is rotated, a finished jar or bottle will be delivered on to the casher plate.
A n:odification of the above-described machine consists in employing only one
pressing mould working in a water-jacketed casing and placed under the mould table
and central with the pressing plunger, the up and down movement being given by
hydraulic cylinder, the valve of which is operated from the master shaft.
To prevent disfiguration of the jar by air lines, the pressing mould (as are the
pressing moulds previously described) is divided longitudinally into any convenient
number of segments so fitted and bound together by hoops that the air under
compression in the pressing operation may escape through the divisional joints
separating the different segments. The delivery of the finishe jar in this modified
machine is effected by a sliding ram operated through horizontal shaft, pinions, racks,
or their equivalents, by the piston rod of the pressing mould. The final delivery of
the jar on to the table of the balanced tippler, and its subsequent gravitating rolling
movement on to the casher plate being the same as in the previously described
machine.
A further modification consists in employing only one mould cover to serve the
full number of compound moulds employed, the cover having an intermittent vertical
up and down movement given to it by cylinders of similar construction to those
previously described.
It will be well understood that instead of using hydraulic cylinders for working
the sliding pressing mould, the pressing and blowing plungers, cams or other
equivalent means may be used.

We DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the County of
York, Glass Bottle Manufacturer, and CHARLES EMMETT of 194 Doncaster Road in
Barnsley aforesaid, Mechanical 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:-
This invention relates to improvements in automatically operating the various parts
pertaining to the bottle or jar making machine for which Letters Patent were granted
to Jaines Richard Windmill and numbered 8526 A.D. 1886 in such a manner that
after the molten metal has been by hand or otherwise placed in the mould, the
machine will then perforin the various operations necessary for the production
completion and delivery of the bottle or article required, and we carry out our
invention in the following manner :-
A suitable number of moulds are arranged around the outer upper surface of a
circular table capable of an intermittent revolving movement around a vertical
central fixed pillar, the revolving movement being effected by ratchet wheel attached
by sleeve to the underside of mould table. This ratchet wheel is actuated by crank,
connecting rod, and pawl, and driven by frictional cone gearing in such a manner

page_text: :
that after the crank has made one complete revolution and rotated the mould table
the desired distance, a spring detont will become engaged in a notch provided for
it on the rim of a disc wheel carried by crank shaft, at the same time breaking
contact between the frictional driving surfaces, thus stopping further movement of
the crank. To still further secure the mould table by monentum from overrunning
itself, a second spring detent is provided capable of engaging with notches cut in
an annular rin formed on underside of mould table.
Each of the moulds carried by the mould table are compound, and consist of a
sliding cylindrical pressing mould having a cavity formed on its upper surface and
working in a tubular guide attached by flange to undersurface of mould table. This
pressing mould has an up and down movement given to it by means of antifriction
runners or bowls running on the upper surface of a fixed annular roadway formed
with ascending and descending inclined planes on portions of its circumference, the
other portions being level. Central with and above the tubular guide and pressing
mould, the mould table carries the blowing mould which is built up in two sections,
the lower part constituting the body portion, and the upper the neck and part of the
mouth portion, the upper section being in two parts and hinged. Carried by and
hinged to the body mould is a cover by which the compound mould is closed, and
which is formed to produce the remaining mouth portion; this covered is opened
and closed after the manner of a box lid by bowls working on circular inclines and
depressions carried by a disc attached to and surrounding central pillar. Through
the above mention cover, a water-cooled pressing plunger for operating upon the
molten metalin the pressing mould is free to work and has intermittent reciprocating
motion given to it by means of an hydraulic piston and rod, the cylinder containing
such piston being supported by a bracket carried by the central pillar. A portion
of the lower part of the body mould is cut away for the entrance and withdrawal of
an arm forming part of a bell-cranked lever having movement in a horizontal
direction given to it by a runner or bowl carried by one of the limbs of the bell-
cranked lever working in a fixed cam secured to and surrounding central pillar.
The other end of the bell-cranked lever is partly circular in plan view and enlarged
to fit the bore of the blowing mould, and has a hole formed through it centrally for
the reception of the smaller diameter of a disc that is turned circumferentially to two
diameters, the larger diameter resting on the upper surface of lever, the upper
surface of the disc being formned to the configuration of the bottle or jar to be
produced.
A blowing cylinder also carried by bracket from central pillar and fitted with
piston and rod and having constant pressure exercised on its smaller and under area
(as is also the case with the pressing piston) has its lower end fitted with a washer
of jointing material, such as asbestos, and is furnished with an arrangement of
automatic blowing valve referred to hereafter.
The valves operating the pressing and blowing cylinders are actuated by cams
carried by a master shaft suitably situated and timed to make one revolution in the
time required for the various operations requisite in the making of the bottle, after
which operations have been performed the shaft with its cams is stopped by detent,
and will remain so till the detent is again withdrawn for the next series of
operations.
The blowing plunger has attached to it a blowing valve casing containing a valve
the stem of which works through a gland formed on the cover of casing. The end
of the spindle carries a weight ensuring the valve being kept closed and tight on its
seating till the descending blowing plunger causes the valve spindle to be arrested
and stopped in its course by the end of a counterweighted horizontal lever the
counterweighted end of which rests on a fixed stop. The plunger and valve casing
continuing to descend cause the valve seating to leave the suspended and arrested
valve, allowing air under pressure to pass and enter a port communicating with the
interior of bottle to be blown.
The action of the above-described machine is as follows: any convenient number

page_text: of moulds may be used, but for clearness in the description we will follow the move-
ments of one mould and its accessories through the various operations required during
the making of a bottle or jar.
One of the sliding pressing moulds having by rotation of the mould table arrived
at the ladling or charging position, and through action of the aunular inclined plane
and runner having reached the charging level in the interior of blowing mould, and
the upper portion of mould being shut, molten metal is now charged into the
cavity contained by the pressing mould; after which the mould cover by still further
rotations of the table and the action of the runner and inclined plane is caused to
close the mould; by the time this has been done the closed mould will have arrived
at the pressing position under the pressing plunger. The plunger descending forces
the molten metal into the space bounded internally by the plunger and externally by
the pressing and mouth portions of the mould, completing the formation of the neck
and mouth of the jar. The mould table being again caused to rotate will, by
reason of fixed inclined plane and runner, lower the pressing mould into its lowest
position, leaving the partly formed bottle suspended by its mouth in the interior of
blowing mould. The sliding pressing mould. being now out of the way, the bell-
cranked lever carrying the mould bottom and operated by the fixed cam and runner
is free to enter through the side opening formed in the bottom portion of blowing
mould. The mould table still continuing its movement again elevates the sliding
pressing mould, which in its turn lifts the mould bottom carried by the bell-cranked
lever to a sufficient height to enter and close the bottom of the blowing mould. By
the time this has been accomplished, the mould with its partly formed bottle will
have arrived in position under the blowing plunger, which descending makes an air-
tight joint with the cover portion of mould; the blowing valve having been opened
as previously described, air under pressure is free to enter the interior of the partly
formed bottle, expanding and causing it to fill and fit the interior of the blowing
mould. The blowing plunger now ascending, and the mould table again being put
into motion, will result in the mould cover rising and uncovering the mould, in the
neck portion of the mould opening, in the descent of the pressing mould to its
lowest position, in the withdrawal of the movable mould bottom, and in the further
ascent of the pressing mould to the delivering position carrying with it and elevating
the finished bottle till it is above and clear of the upper surface of the mouth mould.
Then by action of a pusher arın worked by blowing plunger the bottle is carried
from the ring-like upper surface of the blowing mould on to the table of a counter-
weighted tippler, on reaching which the weight of the bottle being greater than the
balance weight will cause the bottle to be turned from the vertical to a horizontal
position, when it will by gravity roll on to the casher or delivery plate, and from
thence by hand to the annealing ovens.
It will be seen that the whole of the above-described operations constituting
charging, pressing, blowing, and delivery of the bottle, are going on at one and the
same time, and with the exception of charging the mould all the operations take
place automatically; and it will also be understood that every time the mould table
is rotated, a finished jar or bottle will be delivered on to the casher plate.
A modification of the above-described machine consists in employing only one
pressing mould working in a water-jacketed casing and placed under the mould
table and central with the pressing plunger, the up and down movement being
given by hydraulic cylinder, the valve of which is operated from the master shaft.
To prevent disfiguration of the jar by air lines, the pressing mould (as are the
pressing moulds previously described) is divided longitudinally into any convenient
number of segments so fitted and bound together by hoops that the air under com-
pression in the pressing operation may escape through the divisional joints separating
the different seginents. The delivery of the finished jar in this modified machine is
effected by a sliding ram operated through horizontal shaft, pinions, racks, or their
5 equivalents, by the piston rod of the pressing mould. The final delivery of the jar
on to the table of the balanced tippler, and its subsequent gravitating rolling move-
ment on to the casher plate being the same as in the previously described machine.

page_text: A further modification consists in employing only one mould cover to serve the
full number of compound moulds employed, the cover having an intermitted vertical
up and down movement given to it by cylinders of similar construction to those
previously described.
It will be well understood that instead of using hydraulic cylinders for working
the sliding pressing mould, the pressing and blowing plungers, cams
equivalent means may be used.
or other
The nature of our invention and the manner of carrying it into effect will be
readily understood on reference to the five sheets of drawings hereunto annexed and
the following explanation thereof.
Figs. 1 and 2 are front and side elevations;
Fig. 3 a sectional elevation showing one of the moulds in the pressing position;
Fig. 4 a plan view of mould table showing the shoulder moulds and the means for
opening and shutting the same;
Fig. 5 is a detail of the blowing cylinder; and
Fig. 6 a plan view with the mould table and upper portion of machine removed.
I is the central fixed pillar around which the circular mould table 2 is caused to
intermittently rotate and stop by means of ratchet wheel 3 secured to the boss of
the mould table 4, movement being given to the ratchet wheel by ratchet lever 5
and pawl 6 by means of crank plate 7 and connecting rod 8; 9 is a female cone
carried by horizontal shaft 10 and having constant motion given to it by belt; 11 is
a male cone which by means of bell cranked lever 12, connecting link 13 and
treadle 14 is capable of a sliding movement on shaft 10, and so becoming engaged
or disengaged with the constantly running female cone 9; 15 is a sliding detent shaft
supported in bearing 16, 16, and carrying by pin 17 at its upper end a detent 18;
19 is a spiral spring acting in compression between collar 20 and lower bearing 16,
21 a link connecting treadle 14 and sliding detent shaft 15; 22 a horizontal detent
carried in a bearing formed in the upper frame work 23; 24 are connecting links
between the upper end of bell cranked lever 12 and detent 22, a spring in com-
pression 25 serving to withdraw the male cone.
The action of the above described rotating mechanism is as follows:-The outer
end of the treadle 14 being depressed (by means to be afterwards described) will
result in the simultaneous withdrawal of the detents 18, 22 from the notch 26
formed in rim of mould table and the notch 28 formned on a rim carried by the
I bevel wheel 27, to the bringing into contact of the frictional surfaces of the male
and female cones 11, 9, to motion being then given to the horizontal shaft 10 and
through bevel wheels 29, 27, vertical shaft 30, crank plate 7, connecting rod 8,
to the ratchet wheel 3 carried by mould table. When the mould table has been
rotated the desired distance one of the notches formed in rim of mould table will
have arrived in position over the detent 18 which will by action of the spring 19
rise and enter the notch, thus accurately and securely stopping any further move-
ment of the mould table. The crank will now have made one half revolution and
: it is necessary that before stopping it should make the complete revolution and come
to rest at the point from which it started. It will be seen that the male cone
cannot leave the female till the notch 28 on rim of bevel wheel 27 has come opposite
to and central with the horizontal detent 22, when the power exerted by the
spring 25 will withdraw the male cone and leave the crank plate in position for
again rotating the mould table when the treadle is again depressed.
Figs. 1, 2, 3, and 4 show the arrangement of moulds and their operating
mechanism. In Fig. 3, 31 is a water jacketed casing carried by legs from
foundation plate 32, 33 a sliding pressing mould having a cavity 34 forined on its
upper end, 35 is the body mould through which the pressing mould is free to
work, 36 the shoulder inould in two halves and hinged together at 37, the
mould cover 38 which has an up and down movement given to it by the two
hydraulic cylinders 39, 39, the downward movement being given by pressure
admitted on the upper surface of rams 40. On the pressure being released the
spiral springs 41 will restore the rams and cover to their original position, or in

side of a piston and intermittent pressure on the upper and larger area.
lever for locking together the shoulder mould 36 during the pressing and blowing
operations, 43 a bell cranked lever carried by fulcrum pin 44; the shorter arm of
the lever is furnished with a bowl 45 running on the outer circumference of a
fixed cam 46 secured to and surrounding the central pillar 1. The other end of the
bell cranked lever is partly circular in plan view and enlarged to fit the bore of the
blowing mould, and has a hole formed through it centrally for the reception of.
the smaller diameter of a disc 47 that is turned circumferentially to two diameters,
the large diameter 48 resting on the upper surface of lever, the upper surface of the
disc being formed to the configuration of the bottom of the jar or bottle to be
produced; 49 is a water cooled pressing pin or plunger, 50, the water cistern through
which water is constantly flowing; 51 the pressing cylinder furnished with a piston 52
and rod 53; constant pressure is maintained on the under and smaller area of piston
which is overcome by the pressure acting on the larger and upper area when the
outdoor or pressing stroke is made. 54 is the pressing mould cylinder and 55 the
piston having constant pressure on its upper and smaller area which is overcome by
intermittent pressure acting on the lower and larger area. The rod is guided at 56
(Figs. 1 and 3). Carried by the rod 55 is a pendant 57 (Figs. 1 and 3) the duty of
which is to depress the outer end of treadle and so put into operation the rotating of
the table as previously described.
Fig. 5 shows in detail the apparatus for blowing the pressed jar or bottle into the
blown or finished state. 58 is an arm carried by central pillar 1, 59 a cylinder, and 60
the ram carrying at its lower end an enlargement on the underside of which a washer
of asbestos 61 or other jointing material is secured by the nut and washer 62, 63 is
the blowing valve casing carried by the enlarged portion of ram, 64 a piston valve
having its seating at 65, 66 the inlet for the compressed air, 67 a stop acting also as a
guide for piston valve stem. In the view shown the ram is at the bottom of its outdoor
stroke and the regulating nuts 68 on valve stem being arrested by the guide stop 67
have stopped the downward movement of the valve; the valve casing continuing to
descend results in the valve seating leaving the valve, allowing air to pass through
passage 69 into the interior of the jar or bottle to be blown. On pressure being
released from the upper surface of the ram the action of the spiral springs will restore
the rain to its indoor position and in so doing will close the blowing valve.
Figs. 1, 2 and 6 show the arrangement for lifting the mould bottom or disc 47.
70 is a pillar secured to base plate 32, 71 a sliding rod having a bearing 72 in the
pillar, 73 a bracket, forming a fulcrum for the beam lever 74, 75 an arm carried by
enlarged end of blowing cylinder ram, 76 a link connecting the arın 75 and beam
lever 74, the sliding rod carries at its upper end a platten or table 77. Referring to
Fig. 1 it will be seen that the descent of the blowing plunger will cause the ascent
of the platten or table, and in its ascent it will have lifted the disc or mould bottom 47
carried by the bell cranked lever into the interior of the mould in which the blowing
operation is about to take place.
Figs. 1, 2, 3, 4 and 6 show the arrangement for the delivery of the finished jar
or bottle from the machine to the table of the balanced tippler 78; 79 is a frame
carried by base plate, 113 the injecting cylinder furnished with piston and rod 114,
the upper end of rod carrying a platten 115. Constant pressure is maintained on
the upper and smaller area of piston which is overcome by intermittent pressure
acting on its under and larger area. Carried by frame 79 at its upper end is a
shaft 80 on which a counterbalanced tippling plate 78 is free to work. The operation
of delivering a finished jar or bottle is performed in the following manner-Upon
one of the moulds having arrived in the delivery position as shown at 81 (Fig. 4) and
the mould shoulders having been opened on the passage of the mould from 82 to 81
by the runners or bowls 116 carried by the two halves of the shoulder mould 36.
having been in contact with the fixed wedge shaped plate 83, the bell cranked lever
carrying the disc or mould bottom being by action of the fixed cam 46 and bowl.45
away from the mould in the position shown, and the lever locking the shoulder mould

page_text: having been unlocked by the end of the lever 42 having engaged with the fixed
stop 85 on the passage of the mould from 82 to 81 pressure is now applied to under
area of ejecting piston which by the rod and platten previously described will lift the
bottom of the finished jar or bottle to the level of the balanced tippler plate 78, a
delivery lever 86 having motion given to it by the movement of the pressing piston 52
through crosshead 87, link 88, lever 89, shaft 90, removes the jar as shown in Figs. 1.
and 3 on to the table of the balanced tippler, on reaching which, and the delivery lever
being withdrawn, the weight of the bottle being greater than the balance weight 91
will cause the bottle or jar to be turned from the vertical to a horizontal position,
when it will by gravity roll on. to the casher or delivery plate (not shown in the
drawings) and from thence by hand to the annealing ovens.
The valve operating the various cylinders is shown at 92 (Fig. 2) and has motion
given to it by a cain wheel 93 carried by the mastershaft 94 through bowl 95, link 96,
97.s a pendulum lever supporting end of connecting link 96; the mastershaft is timed
to make one revolution in the time requisite for making a jar or bottle. The outer
end of the master shaft carries a cam 98 which through pendulum lever 99, connecting
link 100, operates the catch lever 101.
The action of the above described machine is as follows:-any convenient number
of moulds may be used--but for clearness in the description we will follow the move-
ments of one mould and its accessories through the various operations required during
the making of a bottle or jar.
A portion of one mould consisting of body and shoulder mould having arrived by
rotation of the mould table at the charging and pressing position 106, the shoulder
mould being closed and locked the pressing mould being at its highest position as
shown by Fig. 3, molten metal is now charged into the cavity 34 formed in upper
part of pressing mould 33. By action of the cam 93 carried by mastershaft pressure
is now admitted to the upper surface of the rains 40 operating mould cover which
now descends and completes the formation of the mould which now consists of body.
mould, shoulder mould, and cover. The further rotation of the cam 98 releases the
catch lever 101, and puts it in the position shown in Fig. 3, when the pressing
piston which had pressure admitted to its upper area simultaneously with the mould
cover rains 40 will descend and the plunger will force the molten metal into the space
bounded internally by the plunger and externally by the pressing and mouth portion.
of the mould, completing the formation of the neck and mouth of the jar or bottle.
Pressure being now released from the upper area of pressing piston the lower area
of piston operating pressing mould and the upper surface of rams operating mould
cover will result in the mould cover rising, in the ascent of the plunger, and the
descent of the pressing mould, leaving the partly formed jar or bottle suspended by
its mouth in the interior of mould. The descent of the pendant 57 causes it to depress
treadle 14 through the sliding collar 102 coming in contact with the projection 103
carried by treadle; the treadle being depressed will rest on prop 104, the pendant
still continuing to descend will cause the inclined lower end (Fig. 1) to come in
contact with the fixed inclined stop 105 carried by base plate, and in so doing will
become disengaged with the projection 103 on treadle, leaving the treadle and with
it the sliding shaft 15 and detent 18 at liberty to ascend when one of the notches 26
carried by rim of mould table arrives over the detent 18 stopping the rotation of the
mould table as previously described.
In the passage of the mould from position 106 to 82 the end of the bell cranked
lever 43 carrying the mould bottom 47 will have by action of cam 46 assume i the
position shown by Fig. 4 the mould bottom 47 being under and central with the
body mould. The blowing ram now descending will cause the platten 77 to ascend,
and lift the mould bottom 47 closing the botton of body mould. The blowing valve
having been now opened as previously described air under pressure is free to enter
the-interior of the partly formed jar, expanding and causing it to fill and fit the
interior of the mould. The blowing plunger now ascending and the mould table again
rotated the mould will have arrived in position 81 (Fig. 4) where the bottle or jar
will be delivered as previously described.

page_text: The mould table again rotating will cause the closing of the shoulder inoulds by
the bowls 116 passing between the two springs 108 which are carried by an arm 109
attached to the central pillar.
The locking of the shoulder mould is effected by the end of the locking lever coming
in contact with the end of the spring 110 (Fig. 4).
Fig. 2 shows the arrangement of piping connecting the hydraulic valve 92 to the
various cylinders, 111 being the constant pressure and 112 the intermittent pressure
pipes.
A modification of the above described machine consists in arranging a number of
moulds of similar construction to those previously described radially around one side
of a central pillar, the moulds being stationary and supported on a table an arm or
bracket carried by central pillar supporting the pressing and blowing cylinders.
Another bracket carried by central pillar supports the pressing mould cylinder, the
ejecting cylinder, and delivering apparatus. The cylinders and delivering apparatus
are of similar construction to those previously described. It will be seen from the
above description and accompanying drawings, that the operations constituting
pressing, blowing, delivery of the jar or bottle, opening and closing shoulder moulds,
locking and unlocking shoulder moulds, operating the mould cover are going on at
one and the same time, and with the exception of charging the moulds all the
operations take place automatically, and it will also be understood that every time
the mould table is rotated a finished jar or bottle will be delivered on to the casher
plate.
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 connection with bottle making machinery the mechanical arrangement
as applied to the rotation and stopping of the mould table as shown in Figs. 1,
2, 3 and 6.
2. In connection with bottle making machinery the master shaft 94 and its auto-
matic working of the hydraulic valve 92 controlling the pressing, mould cover
operating, pressing mould, and blowing and ejecting cylinders as shown by Figs. 2
and 3.
3. As applied to bottle making machinery the bell cranked lever 43, fixed cam 46,
and the means adopted for raising the mould bottom 47, as shown by Figs. 1, 2, 3
and 4.
4. As applied to bottle making machinery the locking lever 42 and method of
locking and unlocking shoulder moulds as shown by Figs. 1, 2, 3 and 4.
5. The mechanical arrangement as applied to the delivery of the finished jar or
bottle as shown by Figs. 1, 2, 3, 4 and 6.
6. In connection with bottle making machinery, the catch lever 101 and its auto-
matic holding back of the pressing piston 52, till the other pistons and rams have
completed their strokes as shown by Figs. 1 and 3.
7. The arrangement of machine having stationary moulds arranged radially around
one side of a central pillar, the operating cylinders being supported by arins carried
by the central pillar.
8. The general arrangement, construction, and combination of the various parts
constituting the above described machines, substantiallyas and for the purposes herein
set forth.
