Improvements in Machines for the Manufacture of Glassware.
I, CHARLES EDWIN BLUE, of the City of Wheeling, in the County of Ohio and
State of West Virginia, Inventor and Manufacturer, 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 :-
My invention relates to improvements in machines for the manufacture of glass-
ware, the object of my invention being to provide a machine wherein a press and a
blow mold are provided, means for pressing the glass into a blank removing the
blank from the press mold and delivering it with the blow mold, and means for
blowing the pressed blank to the form of the finished article.
I have devised several mechanisms for carrying out my invention, one of which is
in effect a modification of the other, and which are illustrated in the accompanying
drawings, in which

Referring now to Figures 1, 2, 3, 4, and 5, which illustrates one form of my
invention, A indicates a base preferably supported upon wheels, the base having at
one end a support B for the press mold table D, and at its opposite end a support C
for the blow mold table E. The press mold table D is provided with a gear F
adapted to intermesh with a gear G upon the blow mold table, whereby the turning
of the table will cause a corresponding turning of the co-operating table.
Situated upon the press mold table B is a series of press molds a, b, c, and d. The
press mold consists of two plates 1 and 2 which are hinged together at their inner
edges upon a support or post 3, projecting upward from the table D. Co-operating
with the press inold body are the neck rings e which also consist of two or more
parts 1-2 hinged together whereby the neck ring may be opened for the purpose
of releasing the finished blank. These neck rings are separate and independent
from the press inold body, and are supported in position thereon through the medium
of the arms H which are supported upon the poet I projecting from the press mold
table D at a point inside the inner side of the press mold as clearly shown in
Figures 1 and 2.
Projecting from the support B is a column J which forms the journal upon which
the press mold table 1 turns. This column or standard projects considerably above
the table as illustrated.
For the purpose of automatically opening and closing the parts of the press molds,
the standard or column J is provided with a cam K, which being connected
immovably with the column is stationary in relation to the table D and its molds.
Connected with each part of the press mold is a link f having its outer end pivotally
conuected with the block which carries at its inner end preferably, a friction
wheel i entering the said cam K. The springs have one end connected with the
table D and their other ends engaging the block g whereby the block is held in
normal contact with the cam, thus following its contour as the table is moved around
it. When the block g is upon the bulged portion of the cam K, the molds are closed
as shown at a, c, and d. When however the block is at the cut away portion of the
cam as shown at the blow portion d, the two parts of the mold are thrown open as
clearly shown. When the mold is open, the ring e carried by the mold is supported
by the arm H as will be readily understood. The table D is provided with a handle L
between the molds and at the under side thereof, the inner ends of the handle L
adapted to engage with the support B as clearly illustrated in Figure 2, whereby
the table is supported in its proper position for the pressing and blowing action as
will more clearly appear hereinafter.
The blow mold table D is provided with a plurality of blow molds M, consisting
of two or more parts as clearly illustrated in Figure 1, which are hinged together at
their inner sides in the usual way. Projecting from the support B is a short column
or projection N which forms a bearing for the blow mold table E, as shown in
Figure 2, around which the table rotates. Secured to the upper end of this
projection N is a cam P. The blow molds have connected to each of their parts
the link m, the inner ends of the links being connected with a block n which
carries at its inner side a friction wheel p adapted to engage the said cam P as the
table is rotated around it. The block n of each mold is connected through the

page_text: medium of springs Q, whereby the blocks are normally drawn inward. This
arrangement of drawing the blocks inward may however be varied as will be readily
seen without affecting my invention, the main object of which is to hold the blocks
normally inward and springs similar to the springs shown in connection with
the table D may be used instead of the springs Q for that purpose. When the
blocks n of the blow mold are forced outward through the medium of the cam P
as shown at the blow position, the blow molds are closed, and when they are
permitted to be drawn inward by the springs owing to the shape of the cam, the
parts of the blow mold are opened as clearly illustrated in Figure 1. When the
blow molds reach the "discharge" position of Figure 1, they are open owing to
the shape of the cam P.
Projecting from the column, or standard J is an arm R carrying at its outer oud
a cylinder S. This cylinder is provided with a piston bead T and a piston rod U
which extends preferably through the cylinder and carries at its lower end a
plunger V for forming a blank shown in Figure 2. This plunger is of the usual
shape, and projecting from the piston rod U is an arm 8 which carries a blow
head t. This blow head t is of the construction fully shown and described in my
patent of June 15th, 1897, No. 14481, whereby when the blow head is seated air
is automatically admitted within the blow mold for expanding the blank, and
when raised the air is automatically cut off. Therefore the operation and
construction of this blow head need not be here described. Projecting from the
piston rod U is the arm s, which as before stated supports the blow head whereby
the blow head and the plunger are worked together. Extending from the column
at a point above the arms is a rod u through which the standard w of the blow
head passes and by means of which it is guided in its movement. Owing to this
construction it will be noted that the blow head and plunger or presser
head are attached, whereby when the presser head is moved the blow head is
correspondingly actuated.
The operation of my invention is as follows:-Glass is placed in one of the press
molds at the "charging" position, and the table D rotated to bring the charged
mold into the pressing position. In this position the plunger is depressed through
the medium of the piston rod, and withdrawn from the mold which forms the
blank .
The table D is then rotated to carry the mold from the pressing to the
blowing position, and in this movement the two parts of the press mold are opened
through the medium of the cam K and the springs as clearly shown, and the blow
mold is closed around the depending blank which is supported by the neck ring,
which is in turn supported by the arms H.
When the pressed article has reached the blow position (Figure 1) and the blow
mold closed therearound, the ring e inter-locks with the blow mold (see Figure 2),
and the further rotation of the table carries the blow mold with the ring e to the
discharge position, the arms H simply sliding from under the ring as the tables are
rotated in much the same manner as one cog of a wheel becomes disengaged from
another wheel when they are rotated. Before the blow mold reaches the discharge
position, the blow mold is automatically opened, and the discharge boy receives the
ring with the blown article and opens it taking the article therefrom, and again
places the ringe upon the arm II of the table D at the point preceding the charging
point (Figure 1). There is preferably a neck ring e for each press mold, and
preferably as many blow molds as there are press molds. From this description it
will be noted that the blank is delivered from the press mold to and within the
blow mold, and that while the blank is being pressed, another previously pressed
blank is being blown. The neck rings e are opened and locked closed by means of
the handles 8.
The operation of the piston T is controlled through the medium of the valve
rod A', which passes through the pipes B which communicate respectively with
the upper and lower ends of the cylinder, communicating with these pipes is the
source of pressure supply through the pipes C, and the rod valve A', is constructed
so that when drawn downward air will be admitted above the piston for carrying

page_text: the plunger down, and when released the valve is carried upward by the spring D¹
admitting air below the piston. In each case the valve rod is constructed with an
outlet opening E¹ whereby air is permitted to escape from one end of the cylinder
while being admitted to the other end through the inlet opening E" and E¹¹¹ is a
handle for operating the valve rod.
The blocks g and n of the two tables are provided with collars a sliding upon
the horizontal rod 1, whereby they are supported and guided in their movements
as will be clearly understood from the drawings.
Referring now to Figures 1, 2, 3, 4, 5, 6, and 74, which illustrates another
form of my invention, A² represents a base preferably mounted upon wheels B², and
supported upon this base upon standards C² or in any desired manner, are the
columns E2 and D². These columns are each provided with laterally projecting
flanges F2 at their lower ends, and surrounding the columns and supported by the
said flanges are the revolvuble tables G2 and H2. The tables G I designate a press
mold table, and table H2 a blow mold table. These tables as here shown are
provided with inter-meshing gears I2, which may be separate from and secured to
the table as here shown, or the gear teeth formed integral with the table as may be
desired. Owing to this arrangement the tables revolve in unison as will be readily
understood, and this unity of revolution can be accomplished through the medium
of the intermediate gear if desired whereby the blow mold table H2 would revolve
in the opposite direction from that indicated by arrow in Figure 2, as is well
understood by mechanics.
The press mold table G2 is provided with a plurality of press molds J2, which are
preferably composed of vertical sections and of the usual well known construction,
the sections being pivoted together so that they may he swung open for the purpose
of removing the pressed article therefrom.
The blow mold table H2 is also provided with a plurality of blow molds, also
consisting of vertical sections hinged together, and preferably of the well known
form. These two tables being geared together and revolving uniformly, and one
over-lapping the other as illustrated in Figure 1^, it will be readily understood that
the blow mold of the blow table and the press mold of the press table travel in a.
common intersecting path or point as indicated in Figure 2.
Vertically and revolubly movable upon the column or standard D² of the press
mold table is a ring or collar L2 provided with a plurality of arms M² of a number
preferably corresponding to the number of the press molds, and these arms are
connected with the table G* through the medium of the telescopic or longitudinally
slidable connectious N2, whereby the collar L and its arm are revolved by and
with the table G². These arms as here shown are preferably extended downward,
and the extremities of the arms are provided with a cross head P². Intermediately
pivoted to the ends of this cross head are the arms Q2 having their outer ends
curved and adapted to engage the neck ring R2 which co-operates with the press
and the blow molds, as is well understood by those skilled in the art. Pivoted to
the inner free ends of these arms, levers or jaws Q2 are the links S2, the opposite
and inner ends of the links being connected by a cross link or block T2. These
jaws or arms or levers Q2 are normally held open as illustrated at the charging,
blowing and fixing positions, as illustrated in Figure 2.
The machine is provided with the usual plunger U2 for pressing the glass in the
press mold, the said plunger being actuated through the plunger rod V2, which has
its upper end passing through a cylinder W2, the said cylinder being supported by
the upper end of the column D through the medium of the bracket a². The said
plunger rod V2 is provided with a piston head 62 within the cylinder, and the piston
head is actuated through the medium of fluid pressure which is admitted to opposite
ends of the cylinder through the pipes. The admission of the fluid pressure is
regulated through the medium of a valve rod ², clearly illustrated in Figure 6ª,
whereby the operator is enabled to reciprocate the plunger through the movement
of the valve rod d³, thus admitting air or fluid pressure to either end of the cylinder.

page_text: This construction and operation is well understood and need not be here more fully
described.
A rod e² extends longitudinally within the column D2 and has its upper end
connected with the upper projecting end of the plunger rod V2 through the medium
of a connecting bracket or arm f2, whereby the said rod e2 is moved in unison up
and down with the plunger rod D. The lower end of this plunger rod D2 is provided
with laterally projecting arms or pins g² which project through longitudinal openings
or slots within the column, and are adapted when the rod V2 is moved upward
through the upward movement of the plunger U to engage the underside of the
collar 1, thus lifting the collar L² and its arm or jaws Q2 which carry the neck ring
from the pressing point to the blowing point as will be presently more fully
described.
Projecting laterally from the column D² near its lower end are the cam studs i²,
which are adapted to engage the cross links or blocks T connecting the inner
ends of the links S2 when the collar L and its arms are lowered, whereby the jaws
or arms Q are separated against the tension of the springs F There are three
of these cam studs I, one being situated at the blow point, one at the fixing point,
and one at the charging point, none being provided at the pressing point. From
this it will be noted that the lowering of the collar L2 and its arm when the plunger
is carried down within the press mold for pressing the charged glass therein, that
the arms Q are forced apart at the blowing, fixing and charging points, while they
remain closed around the neck ring R2 at the pressing point. This prevents the
neck ring of the mold at the blowing, fixing and pressing points from being elevated
when the collar L2 is lifted through the medium of the lifting of the plunger, while
it accomplishes the lifting of the neck ring situated upon the mold which is at the
pressing point.
The press table G2 is revolved through the medium of the handles 2, which has
its inner end adapted to engage an opening in the flange F2 of the columu D²
just at the right of the pressing point. The operation by lifting the outer end
of the handles at the right of the pressing point, will disengage its inner end
and can revolve the table to carry the mold which is at the pressing point to
the blowing point, and the mold which was at the blowing point to the fixing point,
and so on throughout the revolution of the table as is well understood. At the
same time the table H is uniformly revolved as before described, whereby the blow
molds are brought to the blowing point, and also to the discharging point to have
the article removed by the turning out boy.
In operation the press molds are charged at the charging point, and the
table revolved taking it to the pressing point. At the pressing point the neck ring
is engaged by the arm Q2 as before described. When the plunger is removed the
table is revolved to carry the mold in which the glass was just pressed to the
blowing point, and the succeeding mold at the charging point has been charged
with molten glass. The removing of the plunger has elevated the ring L2 and its
arms, and hence the neck ring R2 which is co-operating with the press mold at the
pressing point is elevated through the medium of the jaws or levers Q2, which
withdraws the pressed blank or blanks from the pressing mold and moves it
upward. The parts of the press mold are then opened outwards as shown at the
blowing point in Figure 2 by the press operator, or they may be opened
automatically, to be out of the way of the blow mold when they reach the blow
point. The table having been revolved to carry the pressed blank over the
blowing point, the movement of the plunger to press the glass in the succeeding
press mold will permit the downward movement of the ring L2 and its arms, and
consequently the depositing of the pressed blank within the blow mold. This
movement has thrown the arms Q open as illustrated, and disengage them from
the neck ring which is now deposited upon the blow mold. The blowing is then
effected through the pressure of the foot of the turning out boy upon the treadle ²,
which is connected through the medium of the rod and a lever m with the blow
head rod n² which carries the blow head down upon the blow mold. The blow head is

page_text: constructed to automatically admit and cut off air, as shown in Figure 7, and as
fully illustrated and described in my Patent dated June 15th, 1897, No. 14481, and
need not therefore be more fully described here. Instead of operating the blow bead
by an independent movement however, as just described, this may be accomplished
automatically through the movement of the ring & as illustrated in Figure 1*, and
which will be fully described hereafter.
From this description it will be secu that intermittent rotation of the press
and blow mold tables, and the movement of the plunger will cause the pressing and
the blowing of the article at each movement, whereby a blank is pressed, and a

reaches the discharging point, the neck ring is thrown open and the blow mold also
opens for removing the finished article therefrom. The turning out boy will then
place the neck ring upon the mold at the fixing point, ready to again receive a
charge of glass at the charging point.
In Figures 4 and 5, I show a modification of the construction to the extent of
omitting the press table and substituting therefor a single stationary press mold,
and omitting the blow mold table and substituting therefor a stationary support for
one or more blow molds. In this instance I show a support 2 projecting from the
base A2, which forms the support for the column B². In this construction the neck
ring R, and its arm and levers are the same as heretofore described, and need not

standard 3 which supports the press mold 4. This press mold is of the same
construction as illustrated in Figures 1 and 2^, and co-operating with this press
mold and also to co-operate with the blow mold 5* upon the stationary table or support 6ª
therefor, are a plurality of neck rings 7, which are preferably also of the same
construction as illustrated in Figures 1 and 2. In this modification, it will be
noted and as illustrated, that the neck rings are supported upon the arms or levers Q
of the arm M, and that only one cam stud 8 is provided upon the column B", and
this is at the blowing point. The collar L2 in this instance is provided with a
plurality of projecting arms 9" which form the means for rotating the collar L2 and
its arms M², and these arms 9 are provided with a handle 10ª connected through
the medium of rods 11ª and bell crank levers 12" with a locking pin 13. This lock-
ing pin is adapted to engage a vertical key-way 14ª formed in the column B21, which
will lock the collar L and its arm in the proper position as they are rotated. In
these Figures, the mechanism for raising and lowering the plunger, and for raising
and lowering the collar L is the same as that shown and described in Figures 1, 2,
and 3'.
It will be noted that the blow mold support 6' is constructed here of preferably a

triangular form, though if desired this may be varied.
support is provided with stops 15%, which serve to place the blow molds at the
proper point, upon the said table or support 6 for receiving the pressed blank.
In operation this modification is practically the same as that illustrated in
Figures 1, 2, and 3, in that the neck ring R2, which is upon the press mold 4* is
lifted through the medium of the jaws Q2, removing from the press mold the pressed
blank and carrying it by the revolution of the ring or collar L² to the blow point
and when lowered through the lowering of the plunger for pressing the next blank,
deposit the pressed blank in the blow mold. The arins Q2 release the neck ring at
the blow point the same as described in relation to Figures 1, 2, and 3, and the
nold in which the blank is blown is carried to the discharging point and removed
by the turning out boy. The neck ring is then placed upon the arm Q2 at the fixing
point of Figure 5 for carrying the ring around to again co-operate with the press
mold in its turn.
In this instance, however, the blow head 16 is automatically deposited upon the
blow mold by the downward movement of the plunger rod and the ring L which
carries the arm that in turn supports the neck ring. This is accomplished through
the medium of an arm 17ª, connected with a ring 18 just above the ring L, which
if desired may be connected thereto. Pivotally connected to the ends of this

page_text: arm 17 is a link 18" having its opposite end connected to a lever 19 at a point
intermediate its ends. The inner ends of this lever 19 is pivotally supported by
the column B2, and its opposite end is connected with a blow head rod or tube 20*
through the medium of a link 21. The blow head rod passes through and is
supported through the medium of an L-shaped bracket 22 which has its inner end
bolted or otherwise attached to the column B. It will be thus understood that
when the ring L is moved upward by the upward movement of the plunger, the
blow head 16 is likewise moved and when the ring L2 moves downward with the
downward movement of the plunger for pressing the glass in the press mold the
blow head is correspondingly moved downward and deposited upon the blow mold,
automatically admitting and cutting off air in its movements as described in my
patent before referred to.
As before stated, the mechanism shown in Figure 4' for automatically depositing
the blow head upon the blow mold may be used in connection with the constuction
shown in Figures 1, 2, and 3, in the place of the treadle and that otherwise
the operation of this modification is practically the same as the operation of the
construction shown in Figures 1 and 2, whereby the pressed blank is elevated or
removed from the press mold carried laterally and deposited in the blow mold, the
modification differing only in some details of construction.
Referring now to Figures 1, 2, 3, and 4", which illustrates another form of
my invention, A³ indicates a supporting base preferably supported upon wheels B³
by means of which it is readily moved around as described. I is a support
extending upward from one end of the base A3, and to which the two parts of the
press mold E³ are pivoted at their lower inner corners at the points . Situated
below this press mold E3 is a motor, for the purpose of opening and closing the
molds, which motor in this event comprising a cylinder F3 carrying a piston G³
and a piston rod H³ extending through its upper end. Air is admitted to the
opposite end of this cylinder through the pipes 63, the admission of air to opposite
ends thereof being controlled through the medium of a valve c³ having at its lower
end a treadle ds. The operation of this part of the invention is well understood and
need not be particularly described.
Connected to the upper end of the piston rod H' is cross bar or head 13 to the
opposite ends of which the lower ends of links J³ are pivoted, the upper ends of
these links being pivoted to ears K³ projecting outward from the upper ends of the
two parts of the press mold E. From this construction it will be at once under-
stood that a downward movement of the piston rod separates the two parts of the
press mold thus opening it, and an upward movement of the piston rod closes the
two parts of the press mold ready to receive the charging and pressing operation.
L3 is a plunger rod carrying at its lower end the usual plunger M³ for pressing the
charged glass within the press mold, the said plunger rod passing upward and
through a cylinder N³ carrying within the cylinder a piston P³. Air is admitted to
opposite ends of this cylinder through the pipes 3, and is controlled through the
medium of a valve f³, having at its lower end a handle g³. The operation of this
part of my invention is also well understood for admitting air to either end of the
cylinder for raising or lowering the plunger.
Q3 is a column or standard projecting upward from the base A³ adjacent the
standard D3 for the press mold and surrounding this column is a ring R³. This
ring is supported upon a collar S3 which is clamped in any suitable manner to the
column Q³, and this ring R³ is provided with a plurality of projecting arms U³
having their outer ends of a ring shape as shown at V. The underside of these
ring-shaped portions are provided with jaws 3, with which the neck rings W³ are
constructed to inter-lock for supporting the neck ring through the medium of these
arms U. The neck ring and these arms are provided with registering tongues and
grooves the said jaws of the ring V³ forming the tongue and groove of that
member to co-act with the tongue and groove of the neck ring.
is a standard projecting from the opposite end of the base A³, the said standard
having a projection which forms a bearing for the blow mold table 3, and around

page_text: which the said table is adapted to rotate. Situated upon this table is a plurality
of blow molds m³ adapted to be opened and closed, and which may be of the usual
form. The arms U³ which support the neck ring are adapted to travel in a path
which intersects the path of the blow molds, and at blowing position, whereby the
neck ring will support the pressed article over the blow molds.
The blow mold table 13 is also vertically movable upon the standard j³ as shown
in dotted lines in Figure 1, and this vertical movement is provided by means of any
suitable motor or actuating element. In this instance I show the motor consisting
of a cylinder p³, carrying a piston q³ and a piston rod 1. Air is admitted to the
lower end of this cylinder through the pipe s3 and the admission of the air is con-
trolled by a valve 3 actuated through the medium of a treadle 3 as clearly
illustrated in Figure 1B.
A standard 2B projects outward from the column Q³, and is provided with a
downwardly projecting arm 3b and an outwardly projecting arm 4. These arms
form a support and guide for the blow head rod 5b as shown, and intermediately
pivoted to the outer end of the arm 4b is lever 6b, one end of this lever being
pivotally connected with the blow head rod 5b and the opposite end connected to
the upper end of a link 7, which in turn has its lower end connected with a
vertically movable sleeve w³, around which the blow table 13 rotates. The operation
of this part of my invention is, that when the blow table is elevated as shown in
solid lines in Figure 1", the blow head is depressed in position upon the top of the
blow mold, and air is automatically admitted through the construction of the blow
head which is fully shown and described in my Patent dated June 15th, 1897,
No. 14,481, and need not be more fully described herein.
The operation of my invention is as follows:-
The press mold Es is stationary, and of which there is but one, while there are a
plurality of neck rings and supports and also preferably a plurality of blow molds
supported upon a rotating table. Glass is placed within the press mold at the pressing
and charging point as indicated in Figure 2b. The press mold is then opened
outward leaving the pressed article supported by the ring and its arm U³. The blow
table is in its lowest position, and this pressed article is carried around to the blow
position by rotation of the arms U³. When it reaches this point the table 13 is moved
upward carrying the blow mold around the pressed blank or article, and in this
movement of the press mold, the blow head is carried to position and the article
automatically blown. A further movement of the ring supporting arms as indicated
by arrow in Figure 2" will disengage the arms from the blow rings and then the
blow table is turned in the direction indicated by arrow, and either lowered before
or after it reaches the discharging point. At the discharging point the turning out
boy opens the mold taking out the article and places the neck ring upon the press
mold, ready for another charging and pressing operation. This operation is repeated
as is well understood. The rotation of the supporting arms Us and the blow mold
table 13 is independent, and the arms U3 are locked in proper position to co-act with
the blow mold through the medium of a pin 9 adapted to engage an opening in the
collar S³, the said pin being actuated through the medium of a handle 10b, and its
intermediate rod 11b and bell crank lever 12. The blow table 13 is locked in its
proper position through the medium of the levers 13" having their inner ends adapted
to engage with the sleeve w³ which supports the blow table 13.
While I here show and describe the press molds as opening outward, and as hinged
at its lower inner edge, it will be readily conceived that this mold may be made solid
and to be carried simply up and down through the movement of the piston rod H³
without departing from the spirit and scope of my claims.
While I have here shown fluid pressure motors for actuating the press mold and
the blow mold supports, it will be readily understood that any other form of motor
or actuating member may be used without departing from the spirit and scope of
my claims.
Referring now to Figures 1°, 20, 30, 40, 50, 6", and 70, which illustrate another
form of my invention, A* indicates a base preferably mounted upon wheels B

page_text: which enables the machine to be easily transported and moved around to any desired
point in the factory. Projecting from the center of this base A is a column B¹¹,
around which a table C+ rotates and upon which the table is journaled and supported
in any suitable manner.
The table C is provided with a plurality of elongated openings D* and journaled
to the underside of the table beneath these openings and in the lugs at are the two
parts E which form the press mold or molds.
This table also carries a corresponding number of blow molds F4, which consist of
two vertical portions as illustrated, and these two parts of the mold are provided at
preferably their inner sides with the ears 6 pivotally supported upon the pivotal
rod c' extending from the table at the inner side of the openings D' and intermediate
their ends. These blow molds are therefore adapted to be opened and closed
horizontally for embracing and releasing the presssed blank in a manner to be
particularly described hereinafter. One of the parts F of the blow mould carries
the bottom dt, the other part of the blow mold having a groove adapted to receive
the projecting portion of the bottom d when the two parts of the mold are closed
together as will be readily understood by those skilled in the art.
From this description it will be noted that the pivotal points of the blow and the
press molds are in the same vertical plane, whereby the molds are adapted to close a
common point, so that when the pressed blank is released by the press mold the
blow mold when closed will close around the suspended blank.
A plurality of neck ring molds G are provided, and preferably a number
corresponding to the number of blow molds. These neck rings consist of two parts
hinged together as is commonly the case in machines of this character, but in this
case the neck rings are separate and independent of the two parts which form the
blow molds proper. The neck rings are constructed to co-operate with both the
blow and the press molds.
Projecting from the table at a point inside of the pivotal point of the parts of
the blow mold are standards H and extending outward over the blow and press
molds are the ring supports I, which in this case as shown consist of two
parallel arms adapted to engage grooves or shoulders upon the neck rings and
to support them when the press mold is disengaged from the pressed blank
and to thereby suspend the pressed blank ready to be embraced by the blow
mold.
Situated at the charging and pressing point and upon the base A is a motor
for moving the press mold or molds vertically and in position to receive the neck
ring and the charge of molten glass. As shown in Figures 10 and 2°, and as before
stated, the two parts of the press mold E are journaled to the underside of the
table C. The motor here shown comprises a cylinder J, a piston and rod K+, which
is adapted to be reciprocated within the cylinder by fluid pressure, the fluid
pressure being admitted through the pipes et and controlled through the medium
of a valve f carrying at its lower end a treadle g'. This valve f is constructed
in any well known way for admitting air or fluid pressure at opposite sides of the
piston for moving it to either end of the cylinder. Links h have their upper
ends pivotally connected to the upper ends of the two parts E of the press molds,
and their lower ends pivotally connected with a cross head . This cross head **
is adapted to be engaged by the piston rod K* for forcing it upward, and thereby
closing the press mold when it is at the discharging and pressing point.
The plunger rod L carries a collar or sleeve M* adapted to fit around the outer
side of the press mold and to hold it closed while the plunger is down and presses
the glass within the press mold. When the plunger is withdrawn carrying with it
the retaining member or sleeve M', the two parts of the press mold fall out into the
position shown in Figure 1° and below the table.
The two parts of the blow mold are closed through the medium of a motor or
actuating element which in this instance consists of a cylinder N* supported by the
column B, carrying a piston and rod P. Links * have their outer ends pivotally
B

page_text: connected to the two parts of the blow mold and the inner ends of these links are
connected with a block or cross head 1. These blocks or cross beads are
supported and moved upon the rods mt, which are suitably supported above the
table preferably having their outer ends in the standard H and their inner ends
supported by the hub of the table C. The inner sides of these blocks or cross
heads are preferably curved on the arc of a circle, as shown, whereby they move
around with the table C. the said piston P4 projecting toward the blow position as
shown so that when the table is rotated to bring the blow molds to the blow position
it is in a line with the piston rod to be forced outward to close the parts of the blow
mold as will be readily understood. The piston is actuated by fluid pressure, con-
trolled in any well known manner either automatically or by a handle or treadle.
The plunger rod L is actuated through the medium of fluid pressure preferably,
though other forms of motors or actuating members may be provided for this
purpose. In this instance the said rod passes through a cylinder Q which is sup-
ported by the standard or column B4, and carries a piston R+. Fluid pressure is
admitted to opposite ends of this cylinder through the pipes S4, and is controlled
through the medium of a vertically moving valve rod T4 having at its lower end a
handle U4. This construction is well known and need not be specifically described
whereby air is admitted to either end of the cylinder as desired by the operator.
Projecting outward from the plunger rod L is an arm n' which carries the blow
head rod p, the lower end of the blow head rod carrying the blow head qt. This
blow head q is of the form shown and described in my Patent dated June 15th,
1897, Number 14,481, whereby air is automatically admitted to the blow mold, and
need not be specifically described here. Projecting from the column B", at a point
above the arm n is an arm 84 serving as a guide for the upper end of the blow
head rod p. From this description it will be seen that when the plunger rod L*
is depressed, the blow head is likewise carried down, and the blow head being sup-
ported at a distance equal to the distance between the molds it will be readily
understood that when the plunger is carried into the press mold, the blow head is
carried down upon the blow mold at the blow point indicated in Figure 2°.
The operation of my invention as above described is as follows-The
press mold is charged at the charging and pressing point, and the plunger then
forced therein for producing a pressed blank. The plunger is then withdrawn
from the mold carrying with it the retaining member M, releases the two parts
of the press mold which fall to the position shown in dotted and full lines in
Figure 1. The pressed blank is held suspended by the neck ring through the
medium of the arms I and the table rotated which carries the suspended
pressed blank to the blow point. At this point the piston P is forced outward
and through the medium of the mechanism described closes the blow mold around
the suspended pressed blank. The succeeding press mold has been brought to
the charging and pressing position, and the operation there repeated as before
described, the mold being closed through the medium of the piston rod K' and so
held until the pressing operation has been performed. In this second pressing
operation, the blank which was carried to the blow position and around which the
blow mold was closed, is blown through the medium of the blow head which is
carried thereupon by the movements of the plunger rod as before described so
that an article is pressed in the press mold and blown in the blow mold at the
same time. This operation is continuously repeated, the blow mold then being
carried to the discharging position where it is opened by the turning out boy and
the neck ring released and again placed on its supporting arm I*.
In Figure 3º, I show a modification, in that a single press mold T4, is provided
and supported upon a stationary support a projecting from the base A. This
press mold is in lieu of the plurality of press molds which are carried by the table
as illustrated in Figures 1 and 2º. The machine in all other respects
is the same, and the operation is practically the same. After the
glass has been pressed the mold t falls or is lowered the same
Figures 1 and 2°, to a point below the table, whereby the table revolves around
as in

page_text: over it, carrying the suspended pressed blank by the neck ring the same as in
Figures 1 and 2c. When the blank has been carried to the blow position, then
the press mold is elevated through the opening d in the table ready to be again
charged and the glass therein pressed.
While I here show and describe the press mold composed of pivoted parts, which
swing vertically, it will be readily understood by those skilled in the art that the
press mold or molds may be made solid and simply moved vertically for releasing
the pressed blank and leaving it suspended to be embraced by the blow mold
without departing from the spirit and scope of my claims.
In Figures 6 and 7°, I show the detail construction for actuating the piston N4
automatically. In this instance the hub of the table C is provided with a plurality
of arms 3 provided at their upper ends with laterally projecting cam surfaces 4,
which are carried around the column B1, as the table rotates. The cylinder within
the column B41, is provided with the inlet and outlet pipes 6, and a spring actuated
valve 7 similar to the valve T4 in Figure 4° and operating in the same manner.
This valve has one end projecting through the column as shown at 8c, and adapted
to be engaged and forced inward by the cam surfaces 4° at the upper end of the
arms 3. These cams are so situated that the valve 7 is forced in as shown in
Figure 6º, and then the piston rod P4 is forced outward by fluid pressure into the
position shown at the blow position in Figure 2°, which closes the blow mold as
before described. By means of this construction the piston rod P is automatically
forced outward as the table revolves at the proper time for closing the blow mold,
and when the table is revolved a little further in the direction indicated by the
arrow the cam surface 4c passes away from the end of the valve 7 and it is forced
outward through the medium of the spring 9c, thus admitting air to the opposite
end of the cylinder which withdraws the piston rod and forces the piston to the
opposite end of the cylinder Ne as will be readily understood.

tion and in what manner the same is to be performed, I declare that what I
