Improvements in Machines to be Employed in the Manufacture of
Glass Jars, Bottles, and like Vessels.
I, ARTHUR SOWDEN, of Glen Aire, Baildon, in the County of York, Machine
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for the moulding of jars, bottles and like
vessels of glass, and consists of improved construction, combination, and arrange-
ments of the parts for supplying the "metal' to the presser moulds, the transfer
of the pressed metal to the blowing mould, automatic supply of air for blowing
the opening and expanding of the moulds, the removal and transfer of the finished
jar or other product of the machine, together with other improvements herein-
after referred to and described.
"
"
According to this invention the supply of metal from the smelting tank to the
funnel leading to the presser mould is affected by means of a slide which carries
a dipper ladle mounted on one end of a tilting lever operated by a tappet, the
ladle being carried between the mould and tank to and fro and cooled by spray
or air blast. The metal is supplied through a funnel shaped guide to the presser
mould mounted on a table to which an intermittent motion by star wheel or
like mechanism is imparted. The presser mould is then brough under a press
plunger its upper part or cap receiving the plunger and so the neck of the jar
or bottle is mouldeu whilst an upward presser operating on the under side of the
mould forms the remaining metal into cylindro-conical shape. A further move-
ment of the table will carry the said mould and metal to a lifter motion consisting
of two sliding hollow shafts into which enter two pins on the side of the cap of
the mould, and said shafts by a raising motion lift the cap and metal out of the
presser mould and transfer same to the blowing mould, whereon a lid or cover
attached to the foot of a hollow hanging shaft is lowered onto the mould and a
cam surface opens the tap of the air supply through the blowing shaft, and the
blowing completes the formation of the jar or other article.
The complete jar or other article and its mould are thence carried by the
table forward to a device which expands and opens out the cap of the mould
preparatory to the removal of the jar or other article, the removal being effected
at the next stage of motion of the table by a pair of contracting and expanding
fingers which clip around the neck of the jar or other article, and by a partial
turn carry the jar or other article clear of the machine and deposit it on an
endless carrier or creeper sheet.
The following are features of construction of leading parts of the machine.
The table or tables are radial from a central column. The blowing moulds are
divided vertically and expanded and contracted by a sliding plate operated by an
incline, the sliding plate having reverse slots and pins and a vertical slot and
guide pin. The cap of the mould is made in two parts hinged and is provided
with side lugs and pins by which and the hollow shafts referred to said cap is
lifted off for transfer and opened out for removal of the completed jar or other

page_text: article. The lids of the blowing moulds are forced down and held upon the
moulds by means of a fixed radius presser bar acting on a runner attached to the
upper end of the lid carrying shaft or bar a spiral spring raises the shaft and
lid when blowing is completed, a like spring on upper end of the shaft prevents
any excess of pressure being applied to the presser lid.
The presser plungers are preferably three in number and are radial to their
shaft, so that its intermittent motion conveniently brings a plunger over a presser
mould as the latter are by the table's intermittent motion brought in succession
under the plunger.
The lifter arms for operating the caps of the moulds consist of hollow shafts
mounted and caused to slide in long collars their inward motion being effected by
crank, a rod and crank arm. The lifting motion being obtained from tappet and
lever, the latter operating a vertical rod connected to the lifter arms.
The lids of the blowing moulds are revolved from the central column and are
brought in and out of position radially in relation to the moulds by means of
crank and pin operated by sector or nogging wheels.
The head or cap of each of the blowing moulds is made in two parts or halves
hinged together and provided with side lugs each having a projecting pin which
enters the nollow shafts of the lifter as described, the two lugs rest against two
upright steadying pieces hinged so as to stand vertically behind the side lugs of
the moulds, and the uprights are held in position by means of a safety spring
which affords sufficient resistance or stability as against the advance of the hollow
lifting shafts and avoids breakage by yielding if the pressure is excessive.
At the completion of moulding of the jar or other article the hollow shafts are
by a tappet acting against and overcoming a retarding spring caused to expand
and thereby open out the moulds preparatory to the removal of the finished article
which is lifted out by contracting and expanding fingers as described.
The air for blowing is contained in an air vessel mounted on the head of the
machine there being also a lower platform or table used for fitting and fixtures
and the main movements of the machine being intermittent, star wheel driving is
preferable.

Improvements in Machines to be Employed in the Manufacture of
Glass Jars, Bottles, and like Vessels.
I, ARTHUR SOWDEN, of Glen Aire, Baildon, in the County of York, Machine
Maker, 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 machines to be employed in the
manufacture of glass jars, bottles, and like vessels the object being to construct a
machine which when in use will automatically perform all the operations necessary
to complete the vessel by firstly ladling or scooping sufficient molten metal from
a small tank or cistern which is kept supplied from a main tank. The metal in
the ladle or scoop is conveyed thereby to a point over a pressing mould into which
it is deposited through a funnel like device. A circular table which carries the
various moulds now makes a partial revolution and the mould passes under a

page_text: presser where the metal is pressed into a conical shape but with a finished neck.
The metal is next automatically lifted out of the pressing mould and placed in
a blowing mould which is carried under an air pipe through which air is forced
and the metal blown inside the mould. The mould and vessel are again auto-
matically moved and the shoulders of the mould or that portion which forms the
neck and shoulder of the vessel are moved so that at the next forward movement
of the machine the finished vessel can be automatically removed by a pair of
clips or fingers which grip the neck of the vessel and deliver it into a rising and
falling box which automatically opens and the vessel is deposited on an endless
sheet and carried to the annealing oven.
The several moulds are carried on a circular table having a central vertical
shaft or axis and from such shaft protrude a series of radial arms or shafts con-
nected with presser caps and air pipes and as an intermittent motion is imparted
to the table the moulds are brought under the different radial shafts which perform
the successive operations necessary for completing the jar or vessel.
The heads or caps of the moulds which form the neck or shoulder portion of the
vessel are made in two portions so that they can be automatically opened when
the vessel is to be removed from the mould.
The air for blowing the vessels is contained in an air vessel mounted on the
head of the machine, and there is a platform below the revolving table, which
platform carries various fittings and fixtures. The main movements of the
machine are intermittent and for this purpose star or nogging wheel driving is
preferable, but it will be obvious that different forms of driving mechanism may
be employed, but the form shewn by the drawings annexed and hereinafter de-
scribed I have found to give good practical results.
Such being the nature and object of my said invention the following is a com-
plete description of same, reference being had to the accompanying drawings in
which similar figures of reference refer to the same parts throughout and such
parts are arranged round a circular machine and necessarily only seen from several
different points.

According to this invention the machine is driven by means of a pulley on the
shaft 1 (see Fig. 7) which drives the worm wheel 2 and the gear wheel 3 mounted
on the main shaft 4 whereon is mounted a bevel wheel 5 gearing with a vertical
bevel wheel 6 the shaft of which runs in a sleeve 7 fixed on the lower table 8.
Driven by the bevel wheel 6 is a pin wheel 9 which imparts an intermittent
motion to the table 10 and central column 11 through the star wheel 12. The
metal is supplied by a dipper ladle or scoop through a funnel shaped guide to the
presser mould 13 which is free to slide in a cylindrical holder 14 mounted on
the table 10.
The metal is supplied to a presser mould through a funnel shaped guide A by
a dipper ladle or cup B which dips into the molten metal in the tank C. The
funnel shaped guide A is carried by a rod A' fixed to the lower table 8 of the
machine. The ladle or cup B is made in two parts kept together by a spring B³
each of which is mounted on a tilting lever B₁ which terminates in a boss B²
pivoted on a stud on a bracket C. The bracket C is free to move up and down on
a key on the vertical guide rod I).
a vertical
Mounted on the bracket C is a small shaft E on which are two eccentrics E¹
each of which is connected to an arm 33 on the boss B2 by a rod E². On the
upper end of the shaft E is a star wheel gearing with a pin wheel F on a
sleeve the upper end of which carries a bevel wheel F which gears with wheel G
driven by pinion G¹ which is mounted on a short shaft supported by
slide H. The pinion G¹ receives an intermittent rotary motion in opposite
directions from a sector wheel G mounted on a stud in the slide H through the
arm G connecting rod G operated by the cam G5 on shaft Ge. The bracket C
is lifted or lowered by means of an arm J projecting from a carriage C¹ mounted
on the slide H; the end of the arm J is forked and engages with an annular recess
in the bracket C. The carriage J₁ is caused to travel up and down the slide by
the connecting rod J2, crank J, and nogging wheels K. The vertical guide rod D
receives an intermittent rotary motion in alternate directions by means of a
pinion D¹ on its lower end engaging with a sector wheel L the arm L¹ of which
is connected by rod L to the crank M which receives its motion from the nogging
wheels N.
The cup
The above described mechanism operates in the following manner:-
or ladle B is lowered on the vertical shaft D until it dips into the box or tank C
and is charged with molten metal. The charged ladle now rises up and is swung
round to a position directly over the funnel A. The two parts of the ladle B
are opened by means of the eccentrics E and E¹ which are connected to the
cranks B¹ on the pivoted bosses B2, and the metal falls through the funnel A into
the presser mould B.
The table 10 now receives a partial rotation through the aforesaid star gearing
which brings the presser mould 13 and its cap 13* under one of three plungers 16
arranged radially round a centre column 17 which receives an intermittent motion
through the star wheel 18, pin wheel 19, and gear wheels 20 driven by bevel
gearing 21 from the main shaft 14.
When the presser mould 13 is under the plunger 16 the presser mould is lifted
or raised in its socket 14 by the plunger 22 rod 23 and lever 24 mounted on the
sliding pin 24 which is normally held down by the spring 25 and spring 25",
which presses against a pivoted casting 26 and causes same to be pressed lightly

page_text: down on the lever 24. In case of obstruction the point of contact between the
rod 23 and lever 24 forms the fulcrum and the above described escapement
commonly called a broken back escapement comes into operation and prevents
any further damage. The lever 24 is operated by the tappet 25 on the shaft 46
(see Fig. 4) which raises the plunger 22 until it comes into contact with and
presses against one of three annular dies or moulds 27 mounted radially on the
central column 17. The plunger is now forced down through the annular die 27
into the plastic metal in the presser mould 13 by the cam 28 on the upper cross
shaft 29 driven by the bevel gears 30 and shaft 31 running through the central
column 17 and bevel gears 32 from the main shaft 4. The plastic metal now
assumes the shape shewn by the black outline in the presser mould 13. A
further movement of the machine lowers the presser mould and caps 13* and
the plunger 16 is lifted clear of the mould by the spring 16. The plungers 16
are provided with a spring safety device 16. The table 10 now receives a partial
turn and the presser mould 13 is brought to a lifting device (see Fig. 4) which
consists of two vertical guide rods 32 mounted on the lower table S. Up and
down these two rods a casting 33 slides and is operated by the connecting rod 34,
lever 35, and cam 36 on the shaft 4*, the casting 333 carrying two horizontal and
parallel barrels 33 through which slide two rods 33 which are moved in and
out so as to engage with the lugs 13" and pins 13 in the caps 13 by the crank
and pin 37, arms 37, forked connecting rod 37", and plate cam 37.
When the presser mould arrives under the lifter motion above described the
two rods 23 enter the cap and lift it with the partly moulded jar clear of the
presser mould (see Fig. 7) until the table 10 receives another partial rotation
which brings a blowing mould 42" under the lifter motion which then lowers the
cap and partly moulded jar therein. The rods 333" are then withdrawn from the
cap 13 and the blowing operation commences.
The mechanism connected with the blowing apparatus is illustrated in Figs. 7
and 8 and consists of six parallel pairs of radial arms or guide rods 38 which
project from and revolve round the central column 11 on rollers or bowls 11.
On each pair of guide rods 38 a casting consisting of two parallel barrels 39 is
free to slide and between these two barrels 39 is a vertical cylinder 39 through
which passes a plunger rod 40 the upper end of which is provided with a roller
or bowl 40 and spring safety device 40" and on the lower end of said rod is
an air valve or cock 41 and a loosely mounted cap or cover 42.
The castings aforesaid are moved in and out along the bars or guide rods 38
by six similar nogging or sector pinions 43 (only one of which is shewn) which
are carried by sleeves 43 arranged hexagonally around a bracket 43" revolving
with the central column 11. These sector or nogging pinions revolve round and
intermittently gear with the teeth and recesses 44 and 4+* respectively on the
two opposite sides of a central stationary sector or nogging wheel 44 whereby
each of the pinions receives a half turn which causes a crank 45 fixed to the
pinion shaft to also turn, and the crank 15 engages with a pin 45^ on an arm 15ª
pivoted on the plunger rod 40 and works the casting and barrels 39 out or in.
The air is fed into a reservoir 46 at the top of the column 11 from which
reservoir depend six pipes 46* which pass through guides or hosses in the
bracket 43 and are connected to the air cock 41 by an indiarubber or flexible
tube 46.
As soon as the partly formed jar is transfered from the presser mould to the
blowing mould the lifter rods are withdrawn and the plunger rod 40 and
cap 42 take up a position directly over the blowing mould and the cap or cover 42
is forced tightly against the cap 13 by the plunger rod 40 and bowl 40* which
passes under a sharp incline 47 (see Fig. 4) formed on a curved rail 47 extending
partly round the machine and travels on such rail until the blowing operation is
finished.
At the same time that the cap or cover 42 is pressed onto the cap 13 the air
valve or cock 41 is opened by the spring finger 41 coming into contact with a

page_text: curved rail 41" which extends partly round the machine and is supported at
intervals by rods 41'. Air is then forced through the valve 41 and cap 42 into
the blowing mould 42" and the partly moulded jar assumes the finished shape
as seen in Fig. 7. The jar remains in the mould and the blowing continues until
the table carries the jar and mould to a device which opens out and removes the
cap 13 from the mould preparatory to the removal of the finished jar. A little
before the mould arrives at the opening out and cap removing mechanism the
bowl 40 runs up the incline 47* on the rail 47 (see Fig. 7) whereby the cap or
cover 42 is released from the blowing mould and the blowing is stopped owing to
the rail 4.1" coming to an end thereby releasing the spring finger 41 and closing
the valve or cock 41. The cap 42 with its plunger rod 40 is then drawn out of
the way by the nogging wheels and mechanism above described. By this time
the mould with its finished jar has arrived opposite the opening out and cap
removing mechanism (see Figs. 9 and 10) which consists of two vertical guide
rods 48 fixed at the bottom to the lower table 8, the upper ends of such rods being
supported by a bracket 48 to which is attached the releasing end of the rail 47.
Free to move up and down the guide rods 48 is a bracket 49 which carries two
parallel and horizontal sliding rods 49 which are inserted in the lugs 13 and
pins 13 in the cap 13 by the bell-crank lever 50 pivoted in brackets 50 fixed
to the upright guide rods 48. The lower arm of the bell-crank lever 50 is con-
nected to tee sliding rods 49 by the links 49" and its upper arm is operated by
the upright rod 51, lever 51 and bowl 51 thereon engaging with the plate
cam 51 on the shaft 4" driven by gearing as shewn in Fig. 11 from the main
shaft 4. The rods 49 pass through a cam 52 and are provided with runners 19
which travel up and down the inclined passages or grooves 52 in the cam 52.
When the rods 49 have entered the lugs and pins in the cap 13 the cam 52 is
raised or lifted up by the bar 53 which is connected to the lever 53 and operated
from the shaft by the cam 34 engaging with the bowl or runner 53" on the
lever 53. As the cam 52 is raised the two rods 49 which pass therethrough are
opened out or separated and slide along the horizontal guide rods 49° forming
part of the bracket 49, and the cap 13 which is made in two parts is opened out
and can be lifted clear of the jar neck.
The lifting operation is accomplished by the sliding cross bar 55 which raises
the bracket 49 with its sliding rods 49* and is connected to and operated by the
rod 56, lever 56, and bowl 56" thereon engaging with the cam 56 on the
shaft 4". The cap 13 is now removed clear of the mould, and as it is lifted up,
the runners 49 on the rods 49* travel up the inclined grooves or slots 52 in the
cam 52 and the cap is closed to its normal position and lowered by the above
described mechanism onto the next presser mould which passes under it, and
the rods 49 are then withdrawn ready for use on the next blowing mould.
Each of the blowing moulds 42" is made in two parts with a hinge 42°, and as
each one arrives at the removing and delivering mechanism (see Figs. 12 and 13)
it is slightly opened out by two pins 57 fixed in the mould which engages with
two inclined grooves 57 in a sliding plate 57 the lower end of which rises up
an incline on a fixed block 58. The jar is now loose in the mould 42 and ready
for removal, which is effected by a pair of contracting and expanding fingers or
clips 59 which are held in a closed position by a spring 59 and are mounted
on two pins 59 projecting from the top of a long sleeve 60.
AV shaped fork 61 and rod 61 rest in brackets 61° fixed to the back of the
sleeve 60, the fork 61 being provided with a pin 61° which enters the bracket 61"
and prevents any turning movement but allows of an up and down motion of the
fork 61. The sleeve 60 works on a key on a vertical rod 62 supported at its upper
end by a bracket 63 fixed to the vertical guide rod 48, the lower end of the rod 62
being supported in a footstep bearing 64 carried by the frame 65 bolted to the
lower table 8.
The sleeve 60 which carries the clips 59 is raised or lowered by a forked
clutch GO which fits in an annular recess in said sleeve, the clutch 60 being

page_text: | bolted to a rod or bar 60° which is connected to the lever 66 and operated by the
cam 67 on the shaft (see Fig. 14). The sleeve 60 receives an intermittent
partial rotation or quarter turu in both directions by the bar 68 which has a recti-
linear motion imparted to it by the plate cam 69.
On the end of the bar 68 is a rack 68 which gears with a pinion 70 on the
shaft 62 causing the same to turn first in one direction and then in the other.
The sleeve 60 is prevented from vibrating or backlash by a spring and plunger
rod 71 which bears against a collar 72 on which are two flats. The clips or
fingers 59 are opened out by the inner edges of the fork 61 which is lifted up
or raised by the curved table or platform 73 coming into contact with the end
of the rod ol. The platform 73 is connected to a torked rod 74 which receives
a rectilinear motion from the cam 74* fixed on the shaft 75 which is driven by
bevel gearing 75 from the shaft 4*. Close to the sleeve 60 is a rising and
falling box 6 supported and fixed at one bottom edge to a shaft 70 by the
lugs 76. The shaft 76 carries a pinion 77 which gears with a rack 77" on a
bar 77, rack 77* being kept in gear with the pinion 77 by the guide roller 77',
the lower end of the bar 77 passes through a guide 77" and receives a rectilinear
motion from the cam 78 to roller 78. The rectilinear motion of the bar 78 and
rack 77" thereon causes the pinion 77 and shaft 76 to be turned backwards and
forwards thereby lifting and lowering the box 76. The box 76 is provided with
a door 19 secured to a vertical shaft 79 (in Figs. 12 and 13 the door is omitted
but the position of the vertical shaft 79 is shewn) which receives a partial turn
in one direction by the bevel gearing 79", arm 79 actuated by the cam 80 on
the shaft 75, the shaft being then drawn back to its original position by a
spring 80 attached to an arm 80" secured to the rod 79*.
The action of the removing and delivery mechanism above described is as
follows: When the mould 42 from which the cap 13 has been removed arrives
at the mechanism above described, the mould is slightly opened on its hinges as
before mentioned ready for the removal of the jar. The clips or fingers 59,
which are in a position pointing about over the box 76 and at a level slightly
above the neck of the jar in the mould, are swung round by the rack 68* and
pinion 70 to a position pointing directly over the jar and mould. The curved
platform 73 is now raised by the cam 74* and lifts the rod 61 and fork 61, thereby
opening the clips which are lowered onto the neck of the jar, and the platform 73
now descends and une clips are drawn together by the spring 59* and encircle the
neck of the jar.
The jar is now lifted out of the mould by the forked clutch 60* which lifts the
sleeve 60 by the mechanism already described (Fig. 10 shews the jar in its raised
position) and is swung back to a position directly over the box 76 during which
time the box is raised to a horizontal position ready to receive the jar by the
rack 77 and pinion 77 and mechanism for operating same.
The jar is then lowered into the box, the curved platform then rises again
lifts the fork thereby opening the clips which are lifted from the neck of the
jar to the level suitable for passing over the next jar, the box turns over on its
shaft to a position slightly lower than that shewn in Fig. 13, the door 79 is
opened by the bevel gears and cam as described and the finished jar passes out
onto an endless band or other device by which it is taken away to the annealing
oven or other desired point.
The cap or cover 13 of the moulds is made in two portions or halves (sce
Figs. 15 and 16) one half or portion being provided with lugs and holes 94 and
the other portion with lugs and pins or dowels 93, and the pins engaging with the
holes the cap or cover 13* is held correctly in position but capable of being
quickly opened, when necessary. The cap or top portion 13 of the mould moulds
the neck of the jar, and being narrower than the body, the cap portion 13* must
be removed or opened before the jar can be withdrawn from the mould.
The mould 42 can be automatically opened and its cap or cover portion 13*
locked when closed and automatically unlocked when necessary by the arrange-

page_text: ment shewn by Figs. 12, 17 and 18. A pin 57 is fixed in such portion of the
mould and each pin is received in an inclined groove 57* in the sliding plate 57
the lower end of which is raised when it comes into contact with the fixed
block 58. When the plate 57 is raised, the inclined slots acting on the pins 57
force apart and open the mould 42 each portion turning on its hinge 42. The
cap or top portions 13 of the mould are held together by means of the bolts 95, 95
working up and down in the guides 96, 96 and their lower ends connected to the
pivoted levers 97, 97, the ends of which rest on the cross arms 98, 98 of the
slide 99. When the slide 99 passes up the inclined block 58 it is raised and the
arms 98, 98 raise the outer ends of the levers 97, 97 the opposite ends are lowered
and the bolts 95, 95 drawn below the cap or cover 13 and the latter can be
opened. When the slide 99 moves clear of the block 58 the springs 100-100
acting on the levers 97, 97 pull down their ends and the opposite ends shoot the
bolts 95, 95 outwards up each side of the cap 13* and the latter is locked.
Figs. 19 and 20 are side and plan views respectively of a pressing mould the
body 13 of which it is unnecessary should open and it is consequently made in
one piece as is also the cap or cover portion 13 to which is attached the internal
portion 133 (see Fig. 3) which can be raised and lowered, and when so moved
is maintained in correct position by the pin 14* in the top portion working
through a hole in a lug 14" in the fixed portion 13 of the mould.
Figs. 21, 22 and 23 shew the cap or cover 13 of the moulds with hook like
channels 15" with which the lifter rods 33 engage.
Referring to Figs. 24 and 25 which shew a modified form of mechanism for com-
pressing the metal in the presser mould 13 and consists of a fixed pillar 17ª which
carries a single plunger rod 16" carried in brackets 16" fixed on the pillar 17. The
plunger rod 16" is operated from a connecting rod 18% pivoted thereto and driven by
the disc crank 18% pinion 18* and sector wheel 19% supported in the bracket 19*
carried by the brackets 16. The sector wheel 19% being operated through the
arm 20% connecting rod 20%, lever 20%, and plate cam 20. An annular cap 27** for
automatically pressing down the shoulders of the mould is carried by two rocking
shafts 27 which are operated by the connecting rod 27% and cam 28%.
In Fig. 25 another form of mechanism is shewn for operating the lifter rods 33"
which are pushed forward and withdrawn by the crank and pin 37 which receives an
intermittent rotary motion from the nogging wheels 37% driven by bevel gear-
ing 37 from the shaft 38%. The casting 33 which carries the lifter rod 33 is raised
by the connecting rod 39% lever 39 actuated by the cam 39 on the shaft 38.
Fig. 26 shews a modified form of mechanism. In Fig. 26 the horizontal sliding
rods 49 (see Fig. 10) are operated by the crank and pin 49% (see Fig. 26) which
receives an intermittent rotary motion from the nogging wheels 49 and bevel gear-
