PROVISIONAL SPECIFICATION.
Improvements in Machinery for the Manufacture of Glass Bottles,
Jars, and other similar Hollow Ware.
I, CHARLES EMMET of 228 Doncaster Road, Barnsley, in the County of York,
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
:-
This invention refers to improvements in machinery for the manufacture of
bottles, jars and other similar hollow ware, by the pressing and blowing process,
and consists of a simple arrangement of pressing machine for the rapid production
of the parason jar or bottle, hereinafter refered to as a jar, the parasons so
produced being removed away to two or any suitable number of blowing moulds, to
be therein blown to the desired and complete formation of the jars it is desired to
produce.
In carrying out this invention I mount on a central fixed pillar, carried by a
suitable foundation plate, a circular flat topped parason mould carrying table, this
table being free to rotate around the fixed pillar, and for this purpose is provided
with hand operated handles around its outer circumference. Provision is also made
whereby the table can be stopped and locked at the desired pressing position by
means of a detent or lock engaging with notches formed on the outer circumference
of the table. Attached to and carried by the circular revolving parason mould
carrying table are four or any suitable number of tubular vertical guides, and in
these tubular guides are carried the outwardly cylindrical parason moulds. The
parason moulds are formed at their upper ends into cavities of suitable formation,
the formation varying with the size and formation of the jar it is desired to
produce. The upper portion of the parason moulds are so formed that the mouth
portions of the mould can be readily attached to them, these mouth portions are in
two halves and hinged together in the usual manner. The lip portion of the
parason mould is stationery and is carried by a cantilever arm from the central
fixed pillar. It will be seen that each of the complete parason moulds is composed
of three portions, the lower or body portion, the divided hinged mouth portion, and
the fixed lip portion, and that the fixed lip portion is common to all the parason
moulds. Above the upper surface of the combined parason moulds, a pressing
plunger carried and guided by a tubular guide is free to work in an up and down
direction by means of a pressing lever and connecting link as will be well
understood.
Under the parason mould carrying table and central with the pressing plunger is
placed a vertical hydraulic or equivalent cylinder provided with a piston of the
usual construction, the movements of this piston being controlled by a slide or
hydraulic valve, this slide or hydraulic valve is operated by a detachable link
connection with the pressing lever in a manner to be afterwards explained.
The formation of a parason jar by the above described arrangement of pressing
machine is effected in the following manner.
One of the combined parason moulds consisting as previously explained of a
body portion and a mouth portion having by rotation of the parason table arrived
it the charging position, molten metal is by ladle or otherwise charged into it.
The table on being further rotated will bring the charged parason mould into the
pressing position immediately under the pressing plunger, a slight downward
movement of the pressing lever will by operation of the detachable link arrange-
ment connecting the pressing lever with the valve controlling the hydraulic parason

charged parason mould till the upper portion of the mouth portion of the parason
mould comes into contact with and makes true joint with the fixed lip portion, thus
completing the formation of the parason mould. The pressing plunger now being
by the hand lever caused to descend will cause the molten metal to be displaced
and to assume the formation outwardly of the interior of the parason mould and
inwardly of the exterior of the pressing plunger, this being accomplished and the
pressing lever and with it the pressing plunger being raised to its highest position
will result in the operation of the slide or other valve causing the descent of the
piston and with it of the mouth and body portion of the parason mould, when the
combined parason mould has arrived at its lowest position the now completed
parason and with it the mouth portion of the mould can be removed away from
the body portion and placed in one of the fixed blowing moulds when by admittance
of air pressure it can be blown into the desired form in the usual manner.
During the above described series of operations constituting the formation of the
parason jar molten metal has been again charged into another parason mould ready
for the next pressing operation, and so the formation of the parasons and their
removal from the pressing machine to the stationery blowing moulds is continued
at will.
The blowing moulds are stationery and are so formed at their upper portions
that the mouth portions of the moulds can be readily attached to and detached
from them.
Suitable blowing mould covers are also provided and are arranged in such a
manner as to make an air tight joint with the upper surface of the mouth portion
of the mould.
When the jar has been blown to its full dimensions it is by the mouth portion
removed from the blowing mould proper when it is ready for removal to the
annealing oven.

Improvements in Machinery for the Manufacture of Glass Bottles,
Jars, and other similar Hollow Ware.
I, CHARLES EMMET, late of 228 Doncaster Road, Barnsley, now residing at
9 Christ Church Road, Pitsmoor, Sheffield, in the County of York, Engineer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement —
This invention refers to improvements in machinery for the manufacture of
bottles, jars, and other similar hollow ware, by the pressing and blowing process,
and consists of a simple arrangement of pressing machine for the rapid production
of the parason jar or bottle. The parason jar so produced, being removed away to
two or any suitable number of blowing moulds, to be therein blown to the desired
and complete formation of the jar it is desired to produce.
In carrying out this invention I mount on a central fixed pillar, carried by a
suitable foundation plate, a circular flat topped parason mould carrying table, free
to rotate around the fixed pillar. And for this purpose is provided with hand
operated handles around its outer circumference-provision is also made whereby
the table can be stopped and locked at the desired pressing position by means of a
detent or lock engaging with notches formed on the outer circumference of the
table, attached to and carried by the circular revolving parason mould carrying
table are four or any suitable number of tubular vertical guides-and in these
tubular guides are carried the outwardly cylindrical parason moulds-the parason

page_text: moulds are formed at there upper ends into cavities of suitable formation-the
formation varying with the size and formation of the jar it is desired to produce.
The upper portion of the parason moulds are so formed that the mouth portions
of the mould can be readily attached to them. These mouth portions are in two
halves and hinged together in the usual manner. The lip portion of the parason
mould is stationery and is carried by a cantilever arm, from the central fixed pillar.
It will be seen that each of the complete parason moulds is composed of three
portions the lower or body portion-the divided hinged mouth portion and the fixed
lip portion, and that the fixed lip portion is common to all the parason moulds.
Above the upper surface of the combined parason moulds a pressing plunger
carried by and guided by a tubular guide is free to work in an up and down direction
by means of a pressing lever and connecting link as will be well understood. Under
the parason mould carrying table and central with the pressing plunger is placed a
vertical hydraulic or equivalent cylinder provided with a piston of the usual construc-
tion, the movements of this piston being controlled by a slide or hydraulic valve.
This slide or
hydraulic valve is operated by a detachable link connection with the
pressing lever in a manner to be afterwards explained.
The
The formation of a parason jar by the above described arrangement of pressing
machine is affected in the following manner. One of the combined parason moulds
consisting as previously explained of a body portion, and a mouth portion, having
by the rotation of the parason table arrived at the charging position,-molten metal
is by ladle or otherwise charged into it. The table on being further rotated will bring
the charged parason mould into the pressing position immediately under the pressing
plunger, a slight downward movement of the pressing lever will by operation of the
detachable link arrangement connecting the pressing lever with the valve controlling
the hydraulic parason mould cylinder, cause the piston of that cylinder to ascend,-
lifting the combined charged parason mould till the upper surface of the mouth
portion of the parason mould comes into contact with, and makes true joint with
the fixed lip portion, thus completing the formation of the parason mould.
pressing plunger now being by the hand lever caused to descend will cause the
molten metal to be displaced and to assume the formation outwardly of the interior
of the parason mould, and inwardly of the exterior of the pressing plunger. This
being accomplished and the pressing lever and with it the pressing plunger being
raised to its highest position will result in the operation of the slide or other valve,
causing the descent of the piston and with it of the mouth and body portion of the
parason mould.
When the combined parason mould has arrived at its lowest
position the now completed parason and with it the mouth portion of the
mould can be removed away from the body portion and placed in, and
on, one of the blowing moulds, when by admittance of air pressure it can be
blown into the desired form in the usual manner. During the above described
series of operations constituting the formation of the parason jar, molten metal
has been again charged into another parason mould ready for the next pressing
operation, and so the formation of the parasons and their removal from the pressing
machine to the stationery blowing moulds is continued.
The blowing moulds are stationery-and are so formed at their upper portions
that the mouth portions of the moulds can be readily attached to and detached
from them, suitable blowing mould covers are also provided, and are arranged in
such a manner as to make an airtight joint with the upper surface of the mouth
portion of the mould. When the jar has been blown to its full dimensions it is by
the mouth portion removed from the blowing mould proper, when it is ready for
removal to the annealing oven.

Fig. 1 is a side elevation partly in section of a parason jar pressing machine, and
Fig. 2 an elevation, also partly in section of a detached blowing machine.
Referring to Fig. 1. a is a circular parason mould carrying table free to rotate
around the central pillar pillar b, attached to the parason table or in one piece with

pillars d as shown,-e. f. the mould bottom, in two portions, one portion e being
movable in an up and down direction by the guided ram g connecting link h and

The formation of a parason jar by the above described arrangement of pressing
machine is effected in the following manner. One of the combined parason moulds
consisting as previously explained of a body portion and a mouth portion, having
by rotation of the parason table arrived at the charging position, molten metal is
by ladle or otherwise charged into it, the table on being further rotated will bring
the charged parason mould into the pressing position immediately under the pressing
plunger, a slight downward movement of the pressing lever will result in the
descent of the weighted slotted lever p and this descent will cause the balanced
slide valve o, through bell cranked lever g connecting link valve spindle
move from the position shown and will through the cavity in the valve 1 place the
incoming high pressure air supply port 2 in communication with the port leading
into the interior of the fixed central pillar 3 air entering through this port will
displace the water contained in the interior of the pillar and cause a portion to
flow from thence through pipe 4 port 5 into the lower portion of the parason mould
lifting and lowering cylinder 6 causing the ascent of the leathered piston and ram of
the cylinder and thus lifting the combined charged parason mould till the upper
surface of the mouth portion of the parason mould comes into contact with and
makes true joint with the fixed lip portion g-thus completing the formation of the
parason mould. The pressing plunger now being by the hand pressing lever k
caused to descend will result in the molten metal contained in the parason mould to
be displaced and will cause it to assume the formation outwardly of the interior of
the combined parason mould, and inwardly of the exterior of the pressing plunger,-
this being accomplished and the formation of the parason jar completed, the
pressing lever, and with it the pressing plunger, are now raised to their highest

page_text: position as shown by Fig. 1, resulting in the lifting of the weighted slotted link
and this lifting of the link through bell crank lever q connecting link r cause the
reversal of the slide valve into the position shown, allowing the escape of the com-
pressed air from the upper interior of the fixed pillar through ports 3-4 int>> the
atmosphere. Air under constant pressure from the high pressure air supply port 2
is led by pipe 5 to the upper surface of the piston of the parason mould lifting and
lowering cylinder, causing the descent of the piston with the combined parason
mould, and the return of the water contained in the parason cylinder to the
reservoir formed in the interior of the fixed pillar, from the above it will be seen
that the water pressure acting on the under and larger area of parason lifting piston
overcomes the constant air pressure acting on the smaller and upper surface and
that when the water pressure is withdrawn the constant air pressure will be sufficient
to cause the descent of the piston--and the return of the water into its reservoir in
the fixed central pillar.
When the combined parason mould has arrived at its lowest position the now
completed parason bottle or jar and with it the mouth and shoulder portion of the
mould can be removed away from the body portion and placed in, and on, one of
the body blowing moulds shown in section by Fig. 2 at c, the cantilever arm m
being now 3wung over the now combined blowing mould,-the operation of the
hand levert will cause the the descent of the blowing mould cover and cause an
effectual and air tight joint to be made between the cover and the upper surface of
mould. Air under suitable pressure being now admitted by cock into the interior
of the parason will expand it and cause it to assume the formation of the interior
of the blowing mould. The blowing mould cover being now by hand lever raised
out of contact with the blowing mould-can by the movable cantilever arm m be
swung away from over the blowing mould when the now completed bottle or jar
can by the inner mould bottom e sliding ram g connecting link h and foot treadle i
be raised sufficiently high in the slightly taper body mould as to render its
extraction by the taking out fork without distortion to the jar more easy than it
would be if dependance were placed altogether on the taking out fork.
During the above described series of operations, constituting the pressing of
the jar, and its subsequent blowing into finished form, molten metal has been again
charged into another parason mould, ready for the next pressing operation, and so
the formation of the parasons and their removal from the pressing machine to the
stationery detached blowing moulds is continued.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In bottle or jar making machinery in which the pressing of the parason bottle
or jar is effected by one detached portion of the machine, and the subsequent
finishing and blowing into form by another detached portion of the machine, the
use of any convenient number of parason moulds each complete parason mould con-
sisting of three portions, viz. the lower or body portion, the divided and hinged
shoulder and mouth portion, and the fixed lip portion. The body and shoulder and
mouth portion being capable of an upward and downward movement, and the fixed
lip portion common to and completing the formation of any of the parason moulds
that it may be desired to employ, substantially as described and illustrated.
2. In bottle or jar making machinery having each of the complete parason
moulds built up in three portions, the use of the balanced slide valve and its
controll of the upward and downward movement of the parason mould piston,
through action of the pressing lever k, weighted slotted link p, bell cranked lever r,
connecting link ², and valve spindler, substantially as described and illustrated.
3. In bottle or jar making machinery in which the shoulder and mouth portion
of the parason moulds and blowing moulds are in use during both the pressing and
blowing process, and are capable of an upward and downward movement before

page_text: and after the pressing process the use of the mould cover, operated by hand lever t,
eccentric shaft q, sliding die p, ram n, and moveable cantilever arm m, substantially
as described and illustrated.
