Improvements in Machinery for Making Jars, Bottles, or other
Hollow Ware in Glass.
We, DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley in the
County of York, Glass Bottle Manufacturer, and CHARLES EMMET of No. 194
Doncaster Road, in Barnsley aforesaid Mechanical Engineer do hereby declare the
nature of this invention to be as follows:-
This invention consists in improvements in machinery for the manufacture of
bottles, jars and other hollow ware in glass, and has for its aim the production of a
machine capable of manufacturing bottles, jars or similar hollow ware expe-
ditiously and of good quality, and we carry out our invention in the following
manner.
We provide a circular flat topped parason mould table capable of intermittent
rotary movement around a vertical fixed pillar, the revolving movement being
effected by ratchet wheel attached by sleeve to the under side of the parason
mould table, the ratchet wheel being actuated by crank, ratchet lever pawl and
connecting rod, and driven by frictional cone gearing in such a manner that after the
crank has made one complete revolution and rotated the parason mould table the
desired distance, a spring detent will become engaged in a recess or notch provided
for it on the rim of a disc wheel carried by the upper end of the crank shaft, at
the same time breaking contact between the frictional cone driving surfaces, thus
stopping further movement of the crank and parason table, to still further secure
the parason table by momentum from overrunning itself, a second spring detent is
provided capable of engaging with notches cut in the outer circumference of the
parason table. A suitable number of hollow cylindrical bushes or guides are
attached to and carried by the parason table-and in these guides are free to work
the parason or pressing moulds, suitable means are provided for giving movement
to the parason moulds in an up and down direction and in such a manner that each
parason mould can become engaged with and disconnected from the raising and
lowering apparatus which may consist of an hydraulic, pneumo hydraulic or other
cylinder the piston of which is capable of engaging with and becoming detached
from a circular headed attachment carried at the lower end of each parason mould.
Any suitable number of blowing or finishing moulds which may be cylinder or
open and shut moulds provided with the usual opening and locking apparatus are
carried by cantilever arms attached to a central sleeve, the central sleeve being
capable of intermittent rotatory movement around the central fixed pillar and
above the upper surface of parason table. The upper end of the sleeve carries a
spur wheel driven by a pinion secured to and carried by the upper end of crank
shaft.
Central with and above the upper surface of blowing moulds are plungers working
in tubular guides carried by arms secured to and carried by the intermittently
revolving sleeve, one plunger to each mould, the plungers may be operated by
band worked levers, cams, cranks or other equivalent device but preferably by
hydraulic or other cylinder and weighted piston, the weighted piston may be
loaded with the most suitable weight to suit any size of bottle or jar required and
will by its dead weight ensure a more even pressure being applied to the molten
metal than can be given by any hand worked mechanism or by the direct action of
a piston. In some cases we provide a mould cover operated by suitable cylinders
and pistons in such a manner that one mould cover will engage with and lock the
two halves of the upper portion of mould during the pressing operation.
Each of the blowing moulds is furnished with a blowing apparatus which

page_text: consists of a mould bottom shaped to the configuration of the article it is desired
to make and an air admitting mould cover capable of making an accurate and air
tight joint with the upper surface of mould, the mould bottom and cover are by
screw action-toggle joint-wedge or other suitable movement made capable of
approaching and receding from the blowing mould and when not in use as during
the pressing operation can be swung away from and clear of the blowing mould-
suitable means are provided for automatically admitting the compressed air into
the interior of the parason and for gradually increasing that pressure as the
blowing moulds approach the delivery position.
Any suitable number of parason and blowing moulds may be employed, but for
the purpose of illustration we will describe the action of a machine furnished
with two blowing moulds-two plungers-two blowing apparatuses and six
parason moulds. One of the pressing moulds having arrived at the charging
position, molten metal is charged into the cavity formed in and at the upper end of
the parason mould, the machine being now by foot treadle or automatically set in
motion will result in the frictional cones and spur gearing rotating the blowing
moulds one half of one revolution-that is from the pressing to the delivery
position when the blowing moulds have made one quarter of one revolution the
crank and ratchet wheel movement will come into operation and the parason mould
table will be revolved one sixth part of one revolution, one of the blowing moulds
and the charged parason mould having now arrived in the pressing position and
the parason mould being central with and under the blowing mould the hydraulic
cylinder or its equivalent now elevates the charged parason mould into the interior
of blowing mould the weighted plunger next descending will result in the
formation of the parason jar or bottle, the parason mould descending will leave the
parason jar or other article suspended by the mouth portion in the interior of
blowing mould. The mould cover and mould bottom being by hand or auto-
matically swung into position and central with the blowing mould, the toggle joint-
wedge or screw movement will cause the mould bottom to ascend and fill and
fit. the bottom of blowing mould at the same time that the mould cover is
descending and making joint with the upper surface of mould, this having been
accomplished air under suitable pressure is admitted into the interior of parason
expanding and causing it to fill fit and assume the form of interior of blowing
mould.
In the case of very large jars or bottles it may be better to complete the blowing
process before the machine is again rotated, but in smali jars &c. the machine can
be set in movement immediately after the compressed air is admitted the blowing
continuing during the rotation of the blowing mould to the delivery position when
the formation of the jar or other article will be completed, the attendant will now
release and swing the blowing apparatus away from and clear of the blowing
mould, when the finished article can be removed by hand or after the manner
illustrated and described in Specification 16184, 1889.
During the time of revolution of the blowing mould and the continued blowing
of the jar, the opposite blowing mould and its corresponding charged parason mould
will have arrived at the pressing position when the above described series of
operations are repeated. It will be seen that by employing two blowing moulds―
two plungers-two blowing apparati and any even number of parason moulds, two
bottles or jars of different size and formation can be made by one and the same
machine and that the number of jars &c. of different size and formation that a
machine will make will be determined by the number of blowing and parason
moulds and their accompanying parts.
Or instead of there being one plunger to each blowing mould and that plunger
rotating with that blowing mould, there may be a stationary plunging apparatus
consisting of any convenient number of plungers, each plunger being attached to
and carried by a weighted crosshead working in guides, the crosshead having an up
and down movement given to it preferably by a piston working in an hydraulic or
other cylinder or by other convenient means, the plungers being attached to the

page_text: crosshead in such a manner that they are capable of rotation automatically in a
vertical plane each plunger coming into operation in its turn, so that if there be
three plungers and six parason moulds each plunger will operate upon two parason
moulds cut of the six and will thus have time to cool and become fit for use before
it is again called upon for service.
The object aimed at in multiplying the number of plungers being to avoid the
effects of a single water cooled plunger. In some classes of work a single water
cooled weighted or unweighted pressing plunger may be sufficient, but we prefer
when possible to avoid the injurious effects of a water cooled plunger with its
sudden cooling of the molten metal whilst other portions of the parason are in a
semifluid or plastic condition, thus setting up contractional strains and causing
cracks and crizzels in the mouth and neck portion, and malformation in the
shoulders of the jar in consequence of the metal having become set by the cooling
action of the plunger and so becoming unable to be expanded in the blowing
process to the formation required.
Or there may be one plunger to each blowing mould, and each of these plungers
may be capable of engaging and becoming disengaged from the before described
weighted pressing piston, and when disengaged being held in position by a suitable
catch or detent ready for the next succeeding plunger to become attached to and
connected with the stationary pressing piston.
Another method of applying force to the pressing plunger or plungers is to
operate the plunger or plungers by a suitable counterweighted hand lever, a
swinging attachment or stirrup carried by the pressing end of the lever enabling
the operator's weight to be brought into requisition in the pressing operation-the
upward stroke of the plunger being made by counter weight, it will be seen that
this method of pressing satisfies the conditions of the afore described weighted
plunger and that its use will insure a more even pressure being applied to the
metal than is possible with a hand operated plunger.
In order to still further avoid cracks and malformations we prefer to heat the
compressed air used during the blowing operation a convenient manner of doing
this is to employ a ring or Argand gas burner, surrounded by a chimney lined with
some suitable non-conducting substance, such as asbestos, the compressed air being
led by pipe through the centre of the ring like flame and the burner being
situated close to the blowing apparatus the incoming air will become highly heated
before being admitted into the interior of the article to be blown and expanded
into form. We prefer to admit the heated air in such a manner that the entering
current shall first impinge upon the under surface of the blowing apparatus and so
become diffused, the effect of which will be that there will be a gradual increase.
of pressure acting evenly on all portions of the bottle, thus avoiding the direct
action of a jet of cold air playing first on the bottom portion of the bottle
alone.
Or instead of the previously described parason and blowing mould rotating
machinery we may rotate the parason mould table, the blowing moulds and their
accompanying plungers by the spur wheel gearing alone, dispensing with the crank,
connecting rod, pawl and ratchet wheel, but retaining the frictional driving cones,
the manner of rotation in this case will be that upon the cone friction apparatus
being set in motion, the blowing moulds will commence to revolve (and if there be
two blowing moulds and six parason moulds) when a pawl or catch attached to aud
carried by the revolving sleeve carrying the blowing moulds will come into driving
contact with a stud or projection secured to the upper surface of parason mould
table causing the hitherto stationary parason mould table to be set in motion, and
the blowing mould and its now accompanying parason mould will travel and rotate
together and at the same speed till the frictional driving cones are thrown out of
contact upon the pressing position being arrived at when the driving pawl or catch
will be automatically raised out of contact with the fixed stud carried by the
parason mould table, and will remain out of contact with the stud till one of the
blowing moulds has again arrived in position for rotating the parason mould table. .

page_text: The movements of some of the parts appertaining to the before described
machine and the modifications thereof are controlled by a master shaft giving
movement to a slide or other valve having command of the different cylinders
employed-other movements being given by the rotation of the parason mould
table or the rotating blowing moulds after the manner fully set forth and
illustrated in Specification 16184, 1889.
From the above description it will be seen that any number and combination of
parason moulds-blowing moulds and pressing plungers may be employed and that
if for one class of bottles or jars, two blowing moulds-six parason moulds and
two pressing plungers may be sufficient and may meet all requirements, another
formation of bottle or jar may require more pressing plungers and more parason
moulds, the object being to provide a sufficient number of pressing plungers and
parason moulds to ensure their being kept sufficiently cool and to allow of their
working under the most satisfactory conditions, the object being also to limit the
number of blowing moulds and thus ensuring their working at the greatest heat
compatible with their efficient working.

Improvements in Machinery for Making Jars, Bottles, or other
Hollow Ware in Glass.
We DAN RYLANDS, of Hope Glass Works, Stairfoot Bear Barnsley in the
County of York, Glass Bottle Manufacturer, and CHARLES EMMET of 194 Don-
caster 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 consists in improvements in machinery for the manufacture of
bottles, jars, and other hollow ware in glass, and has for its aim the production of
a machine capable of manufacturing bottles, jars and similar hollow ware, expe-
ditiously and of good quality.
In the accompanying drawings,
Fig. 1 is a front elevation, Fig. 2 a side elevation, and Figs. 3 and 4 plan views
of a machine in which the parison moulds, the blowing moulds, and the pressing
plungers revolve intermittently around a central pillar.

moulds and the means employed for operating the cover and bottom of the
mould.
Figs. 10 and 11 are side and front elevations, and Fig. 12 a plan view of the
table of a machine having a stationary parison mould table, the pressing plungers,
the blowing mould, and parison lifting cylinder, being carried by and secured to
a central pillar in such a manner that they can be brought to operate upon any of
the four parison mouids shown.
Fig. 14 is an elevation partly in section of the blowing mould and the mould
cover and bottom-actuating apparatus shown on a smaller scale by Figs. 10
and 11.
In Figs. 1, 2, 3 and 4, a is a circular flat-topped parison mould carrying table
capable of intermittent rotary movement around the central fixed pillar b, the
revolving movement being effected by ratchet wheel c attached by sleeve d to the
underside of the parison table, the ratchet wheel being actuated by crank e,
ratchet lever, pawl y, connecting-rod h, and crank plate i; j the crank shaft,
k a horizontal shaft, 49, 50 bevel wheels, o a belt-driven female cone running loose
on the horizontal shaft k, pa male cone driving the horizontal shaft by means of
a feather key let into and carried by the shaft, 9 a bell crank lever one end of

page_text: which r 18 attached to the male cone by the neck ring &, a link connecting the
end w of the bell cranked lever to the inner end of the foot treadle y, bearings
for the treadle shaft 1; 2 a lever keyed on to treadle shaft, 3 a link connecting
lever 2 with lever 4, 5 a detent shaft, 6 a detent lever, 7 a horizontal detent
carried in a bearing in the upper frame work 8, g g links connecting the upper
end of the bell cranked lever 10 and outer end of the detent 7; 11 a spring in
compression placed round the stem of the detent 7; 12 are parison moulds working
in cylindrical guides 13 secured to the under surface of the parison table, 14 stops
supporting the parison moulds in position, 15 blowing moulds carried by brackets 16,
the brackets being connected by arms 17 to the annular sleeve 18 encircling the
fixed pillar b; 19 a ring bearing forming a footstep for the annular sleeve 18;
20 cylindrical plunger rod guides carried by the cantilever arms 21, the arms
being attached to and carried by the sleeve 18; 22 pressing plungers, 23 pressing
plunger rods, 24 counterweighted levers, 25 links connecting the cross heads 26
with the pressing levers 24; 27 a spur wheel secured to sleeve 18; 28 a spur
driving wheel, 29 an intermediate wheel, 30 a hydraulic cylinder for raising and
lowering the parison moulds, 31 a piston rod provided at its upper end with a cross-
head 32, the said crosshead being capable of engaging with and becoming dis-
engaged from the headed screws 33 carried by the parison moulds, 34 a hydraulic
valve operated by hand lever 35.
Figs. 5, 6, 7, 8, and 9 (Sheet 4) illustrate the construction of the blowing
moulds, and the means employed for operating the cover and bottom of the mould.
The mould is in two parts or halves, each half being hinged to the other in the
usual manner; 36 is the mould cover; 37 the mould bottom; 38, 38 beam levers,
the ends 39 of which carry the mould cover and bottom; 40 toggle joint links
connecting the outer ends of the beam levers 38; 41 a connecting link, the body
portion 42 of which is cylindrical, and is carried in a bearing 43 formed in one
half of the blowing mould, 44 the mould-locking lever, 45 the air-admitting pipe.
Figs. 5 and 6 show the toggle joints in vertical position, and the mould cover and
bottom in position for the blowing process. In Fig. 7 the action of the toggle
joints have caused the mould cover and bottom to assume the position shown when
being clear of the mould they can be turned into the position shown by Fig. 9,
leaving the mouth and bottom of the mould open.
Any suitable number of parison moulds, blowing moulds, and pressing plungers
may be employed, but for the purpose of illustration we will describe the action of
a machine furnished with two blowing moulds, two pressing plungers, two flowing
apparati, and six parison moulds. One of the parison moulds a 12 (Fig. 4,
Sheet 3) having arrived at the charging position a 12, molten metal is charged
into the cavity 46 (Fig. 2, Sheet 2) constituting the parison mould. The pressing
operator now depressing the pedal end 47 of the foot treadle with through con-
necting link t, bell cranked lever q, connecting links 9, withdraw the horizontal-
detent 7 from the notch 47 formed in the rim wheel 48. The depression of the
pedal end of the foot treadle will also through shaft 1, lever 2, connecting link 3,
lever 4, shaft 5, withdraw the detent lever 6 from the notch it has previously
occupied in the outer rim of the parison mould table a. The act of withdrawing
the two detents will also result in the sliding along the horizontal shaft of the male
cone and thus establish frictional driving contact between it and the constantly
running female cone; the movement thus obtained is transmitted from the hori-
zontal shaft to the vertical crank shaft j by bevel pinion 49 and wheel 50. The
spur driving pinion 28 will now through the intermediate wheel 29 cause the
rotation of the spur wheel 27 keyed on to the upper end of annular sleeve 18.
Thus the required revolving movement will be given to the pressing plungers and
blowing moulds rotating them one half of one revolution, that is from the pressing
to the delivery position when the blowing moulds have made one quarter of one
revolution the crank pin c will have arrived in the position shown in plan view by.
Fig. 4 at c, and will through connecting rod h, ratchet lever f, pawl g ratchet
wheel c, rotate the parison mould table and with it the charged parison mould

page_text: from a 12 to 12 (Fig. 4). The pressing plunger 22, charged parison mould,
and blowing mould, having now reached the pressing position will come to rest
by reason of the notch 47 in the rim wheel 49 coming opposite to the runner 54
carried by the horizontal detent allowing the spiral spring 11 to elongate and
in so doing will cause the runner 54 to enter the notch 47 in the rim wheel 49,
at the same time withdrawing the male from the female cone stopping further
movement of the rotating mechanism. The detent lever 6 will now have entered
the notch formed in the outer rim of the parison mould table. It will be seen
that the purpose the two detents serve to perform is to accurately stop the
pressing plungers, blowing moulds, and parison moulds at the pressing position.
This position being now arrived at, and the charged parison mould being now
central with and under the blowing mould and pressing plunger, the hydraulic
cylinder through action of the hand-operated valve-elevates the charged parison
mould into the interior of blowing mould as shown by Fig. 2. The pressing
plunger next descending will result in the formation of the parison jar or bottle.
The parison mould now descending will leave the parison suspended by the
mouth portion in the interior of blowing mould. The mould cover and mould
bottom being by hand swung into position as previously described, and being
central with the blowing mould the toggle joint will cause the mould bottom to
ascend and fill and fit the bottom of the mould at the same time that the mould
cover is descending and making joint with the upper surface of mould. This
having been accomplished, air under suitable pressure is admitted into the interior
of parison expanding it and causing it to fill, fit, and assume the form of interior
of blowing mould. In the case of very large jars or bottles it may be better
to complete the blowing before the machine is again rotated; but in the blowing
of small jars the machine can be set in movement immediately after the com-
pressed air is admitted, the blowing continuing during the rotation of the blowing
mould to the delivery position, when the formation of the bottle, jar, or other
article will be completed. The attendant will now release and swing the blowing
apparatus away from and clear of the blowing mould, when the finished product
can be removed to the annealing oven. During the time of rotation of the blowing
mould, and the continued blowing of the jar, the opposite blowing mould and its
corresponding charged parison mould will have arrived at the pressing position
when the above-described series of operations are repeated.
It will be seen that by employing two blowing moulds, two plungers, two blowing
apparati, and any even number of parison moulds, two bottles or jars of different
size and formation can be made by one and the same machine, and that the number
of jars, etc., of different size and formation that a machine of this description will
make will be determined by the number of blowing and parison moulds and their
accompanying parts.
Figs. 10, 11 and 12 illustrate an arrangement of jar or bottle making machine
in which the parison-carrying table is stationary, the pressing plungers, the blowing-
mould table, and the hydraulic parison mould operating cylinder being attached to
and carried by a vertical shaft in such a manner that the prossing plungers, the
blowing mould, and parison mould actuating cylinder can be brought to operate
upon any of the parison moulds shown; a is a vertical fixed standard carrying the
stationary parison table b; ca pillar shaft working in a tubular bearing d formed
at the upper end of the standard a, the bottom end of the shaft being carried by
the footstep e. The vertical shaft c carries the plunger slide bracket f, the blowing
mould table g, and the parison mould cylinder arm h; the parison mould-
operating cylinder and the lever for controlling same; k a crosshead carried by
the piston rod and of similar construction to the crosshead described and illus-
trated in relation to Figs. 1, and 4, and capable of engaging with and becoming
disengaged from the headed screws m carried by the bottom of the parison moulds;
n the parison moulds, o the parison mould guides, p a counterweighted pressing
lever fulcrummed to the vertical shaft at q; ra stirrup connected by rod to the
outer end of pressing lever p; sa link connecting pressing lever with pressing

page_text: plunger slide t; u solid pressing plungers which are screwed into or otherwise
secured to the crosshead ; wa shaft carried by slide and on which the cross-
head v, and plungers u u, are free to revolve; y a spur pinion secured to and
carried by crosshead v; za spur wheel carried by stud 1 fixed in bracket 2, the
bracket being formed in one with the pressing slide t; 3 a ratchet wheel formed
in one with the spur wheel; 4 a ratchet lever, 5 a pawl carried by stud from
ratchet lever, 6 a tappet rod furnished with tappets 7, 7; 8 fixed guides formed
in one with the pressing plunger slide bracket, and acting as stops for the
tappets 7, 7.
Figs. 10, 11, 13 and 14 show the construction of the blowing mould and the
means employed for operating the mould cover and bottom. The mould is of the
usual construction, in two parts and hinged together; 9 the mould cover carrying
blowing pipe 10; 11 the mould bottom carried in the V slide 12, 13 a beam lever,
14 a sliding wedge guided in a slot 15 formed in the V slide 12; 16 a link con-
necting the outer end of the beam lever to the end 17 of the sliding wedge, 18 a
handle for working the sliding wedge and ✓ slide, 19 guides for the V slide.
One of the parison moulds being charged with metal, the pressing plunger, the
blowing mould, and parison working cylinder are moved by hand so as to become
central with it. The elevation of the parison mould, the plunging of the parison
jar, and the descent of the parison mould are performed in the manner previously
described in reference to Figs. 1 and 2. The mould cover and bottom are now
moved from the position shown by Fig. 13 to the position they occupy in Fig. 10.
The handle 18 on being pushed by the attendant will first move the V slide
and with it the brackets 20 carried by the V slide, the mould cover and bottom
being now central with the blowing mould. The handle 18 is now raised by
the attendant and the catch 21 formed on the handle liberated from the end of
the slide (see Fig. 14). The sliding wedge is now free to move into the
position illustrated by Fig. 10, and in so doing will lift and accurately close
the mould bottom, the mould cover at the same time descending and making
an airtight joint with the upper surface of mould by reason of the link 16 having
moved from an angular to a vertical position. The blowing of the jar or bottle
being completed the mould cover and bottom can be moved back to their former
position.
"
The method of rotation of the pressing plungers will be readily understood by
reference to Figs. 10, 11 and 12. In Figs. 10 and 11 the rotating mechanism.
is shown in the position attained at the completion of the upward stroke of the
pressing slide t. Fig. 12 shows the position at the completion of the downward
stroke of the slide. From the views it will be seen that the pressing plunger
on its upper stroke having cleared the upper surface of blowing mould will
commence to revolve with its companion plunger by reason of the tappet 7
having come into contact with the stop and guide 8, and in so doing the upward
movement of the tappet rod 6, ratchet lever 4, and pawl 5, will be arrested, the
upward movement of the pressing slide continuing will result in the rotation of
the ratchet wheel 3, spur wheels aud y pressing plungers. Before the com-
pletion of the downward stroke of the pressing slide and plungers, the tappet 7¹
will be in contact with the guide and stop 81 when the ratchet lever 4 will be
elevated into the position shown by Fig. 12.
A modification of this machine (not illustrated) consists in the application of a
hydraulic or other cylinder to work the pressing slide and pressing plungers instead
of the counterweighted pressing lever p. The links (Fig. 10) being attached
to the weighted piston rod of the cylinder, which cylinder can be conveniently
carried from the upper surface of the pressing slide bracket f.
In the machine shown by Figs. 1, 2, 3 and 4, a plunger working cylinder can
also be employed by removing the outer ends of the pressing levers 24, but
retaining the crossheads 26, links 25, and the portion of lever connecting crossheads
with balance weight. The upper ends of pressing plunger rods being made in
similar form to the heads carried by the under surface of parison moulds will

page_text: serve as a ready means for engaging with and becoming disengaged from a cross-
head carried by the weighted pressing piston.
From the above description it will be seen that any number and combination of
parison moulds, blowing moulds, and pressing plungers, may be employed, and that
if for one class of bottles or jars, two blowing moulds, six parison moulds, and two
pressing plungers may be sufficient, and may meet all requirements. Another
formation of bottle or jar may require more pressing plungers and more parison
moulds, the object being to provide a sufficient number of pressing plungers and
parison moulds to ensure their being kept sufficiently cool, and to allow of their
working under the most satisfactory conditions. The object we also have in view
is also to limit the number of blowing moulds, and thus ensure their working at
the greatest heat compatible with their efficient working.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The arrangement of plunger blowing mould and parason rotating machinery
as illustrated by Figs. 1, 2, 3 and 4.
2. The crosshead 32 and headed screws 33 Figs. 1 and 2, whereby the parason
working piston is free to operate any of the parason moulds.
3. The mould cover and bottom closing and opening device as illustrated by
Figs. 5 to 9.
4. The arrangement of machine whereby two or more jars or bottles can be
produced from one and the same machine illustrated by Figs. 1 to 9.
5. The rotating plungers and the method of rotating the same as shown by
Figs. 10, 11, and 12.
6. The mould cover and bottom closing and opening device as illustrated by
Figs. 10 and 14.
7. The general arrangement construction and combination of the various parts
constituting the above described machines substantially as and for the purposes
herein set forth.
