Improvements in Machines for Automatically Gathering and
Delivering Glass in Manufacturing Glassware.
I, WILLIAM FRANCIS ALTENBAUGH, of Tiffin, in the County of Seneca and State
of Ohio, United States of America, Gentleman, 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 present invention is directed to the production of an improved machine
for automatically gathering and delivering glass for the forming work in the
manufacture of glassware, and for providing for the highest capacity in the work
the machine is organized for carrying out my invention in separate operations
with a solid gathering-iron and with a blowpipe.
The principle upon which the machine operates is that of automatically advanc
ing a pivotally-mounted gathering instrument into the working chamber with a
dipping action upon the surface of the molten glass, which it gathers at its
skimming point by being rotated, picking up the glass by layers in a sufficient
quantity for the intended work, then reversing the direction of the longitudinal
movement of the gathering instrument, raising it from the surface, swinging it
out at the side of the machine, and delivering the gather for forming operations
while the carriage is at rest, and then reversing the movement to again advance
the gathering instrument to repeat the operation. For effecting these operations
the present machine embodies novel features in its organization..
In the manufacture of pressed ware the glass is delivered from the gathering-
iron into a press-mold, and in the manufacture of blown ware the gathering-
blowpipe is presented to a forming-block, where the operation is continued by
blowing or putting into the pipe as it is rotated in the machine.
The invention which forms the subject of this Patent is directed to and em-
bodied in the machine in its capacity for use with the blowpipe in forming
the article from the glass delivered therefrom; and the said invention for this
purpose consists of certain novel parts and combinations of parts, which are
particularly and separately pointed out in the claims concluding this specification.
For the purpose of informing those skilled in the art to which my invention
appertains of the nature of my invention and for the purpose of instructing them
how the same may be particularly and advantageously employed I will now
describe the machine whereby it is adapted for use in gathering and delivering
glass either to a molding-press or to a forming-block in the form in which Ï
prefer to employ it: but it will be understood that my invention is not limited to
the precise forni herein illustrated and described, as various modifications may be
made without exceeding the scope of the concluding claims.
For carrying out the invention herein claimed the machine will be described
to produce what is known as "blown ware," in which a blowpipe is employed
to gather the glass and deliver it to a forming-block.
The accompanying drawings illustrate a complete machine designed to secure
the highest capacity for work in one organized structure in the separate operations

page_text: which I have stated, and it will be found a convenient and efficient embodiment of
the invention herein claimed in the operation of the machine for the manufacture
of blown ware.
In the drawings, Figure 1 represents a longitudinal elevation the complete
machine as organized for use with a pivotally-mounted gathering instrument, the
position of which is as advancing into the working chamber. Fig. 2 shows in
detail a side view of the gear connection of the carriage with the sliding gear of
the line-shaft by which the gathering instrument is rotated. Fig. 3 shows in
vertical longitudinal section the chuck device for carrying the gathering instru-
ment and the gear for rotating the chuck. Fig. 4 shows in elevation so much of
the machine, as illustrates the gathering instrument as advancing in a dipped
position skimming the surface of the glass in gathering a charge. Fig. 5 shows
à transverse section of the machine on the line of Fig. 1 showing the gearing
for rotating the gathering instrument from the line-shaft. Fig. 6. is a like
section on the line, showing the flexible shafts 17 connecting the chuck-
gearing and Fig. 7 is a like section on the line y y of Fig. 1 showing the shelf Gi
for sustaining the pivotally-mounted gathering instrument. Fig. 8 shows in top
view the gear by which the gathering instrument is rotated from the line-shaft.
Fig. 9 shows in top view the machine as used with duplex gathering-irons in the
positions they occupy when delivering the gather into the press-molds and the
clutch is out of gear. Fig. 10 shows the gear for swinging the duplex gathering
instruments out at the side of the machine for delivering the gather. Fig. 11
shows the rear end of the machine, the clutch device, the connections with the
power-driven shaft, and the crank cam-lever 25 for reciprocating the carriage and
for actuating the clutch device for controlling the rotation of the gathering-iron.
Fig. 12 is a cross-section taken at the gear end of the machine in front of the
latch-bar 52 and showing its connected lever 53 and the relation thereto of the
cam crank-lever for operating the latch-bar to shift the clutch. Fig. 13 shows; in
side view the device for suspending and automatically placing the blowpipe in its
carrying chuck, and Fig. 14 is a top view of the same as used in the duplex
machine. Fig. 15 shows in top view the clutch and shifting gear-connections and
the relation thereto of the cam crank-lever and the supplemental cam 100 thereon
for engaging the friction gear 34 35 to accelerate the rotation of the blowpipe at
the forming-block, as in Fig. 14 and Fig. 16 shows in detail the end cam 55
and the supplemental cam 100 of the crank-lever in their adaptation for actuating
both the levers 40 and 53 for shifting the clutch and the friction-gear, as in
Fig. 15. Fig. 17 shows in top view the clutch device and connecting mechanism
for rotating the gathering instrument, the line-shaft 24 being engaged by the
bevel-gear 32 83 for comparative slow rotation. Fig. 18 is a like view showing
the line-shaft as being out of engagement with its actuating-gear to stop the
rotation of the gathering instrument when delivering the charge. Fig. 19 shows
a like view, the line-shaft being engaged by the friction gear 34 35 for comparative
rapid rotation of the gathering instrument. Fig. 20 shows in side view the cam
crank lever in its relation to the lever 53; connecting and actuating the clutch for
controlling the movements of the carriage, and also the relation of the lever 40,
connecting and actuating the gear-shifting devices for controlling the rotation of
the gathering instrument; and Fig. 21 shows the way in which the cam crank-
Tever actuates the clutch-lever connections to shift the clutch and the gear-shifter.
For supporting the operating parts of the machine the frame has iron beams 11
of the proper length in vertical alinement one above the other, carried by end
frames 2.2, and upon and between these beams a carriage is mounted for
reciprocating movement. A simple form for the carriage is an iron body of
rectangular form standing vertically and provided with flanged rolls 4, 4, at each
of its corners, mounted to engage and travel with firm movements upon the
beams. At its side the carriage carries the mechanism for gathering and deliver-
ing the glass. The frame has a fixed relation to the working chamber and extends
therefrom, with the gathering instrument mounted and carried in such manner

page_text: as to be caused to travel into and from the chamber and in such relation to, the
surface of the glass as to effect the gathering by a rotating skimming action.
As shown, the working capacity' of the machine involves two separate gathering
instruments, and as the mounting and operating mechanism of each is of identical
construction a"description of such mechanism and the operation of one of the
gathering instruments will be identical with the other."
Near the lower side of the carriage an iron bracket 5 is bolted, standing out
horizontal and has a tubular bearing 6, within which is mounted a tubular
shaft 7, Fig. 5, having fixed on its upper end a sort of turn-table plate 8, having
vertical cheek parts 9, to and between which is mounted by trunnions, Fig. 5,
an arm 10, free to swing on its "trunnions and carrying a chuck for the gathering
instrument. The trunnions of this carrying-arm are mounted about vertically
in line with the axis of the turn-table, and said arm 10 has fixed thereto a suitable
box-casting 11, within which the chuck for the gathering instrument is secured
as in Fig. 3. Preferably this box is located in front of the trunnions of the
carrying-arm, and the provision for 'mounting the gathering instrument consists
of a tubular shaft 12, Fig. 3, arranged to rotate in the said box and having a
flaring open end projecting to receive the gathering instrument, which is
secured therein by screws 13 engaging the angular end c of said instrument
to prevent it from turning within the chuck, while at its swing end the carrying-
arm 10 has a pair of rolls d, on which the gathering instrument has a firm resting
bearing and is held from working out of the chuck by a collar fitting against said
rolls. The other end of the chuck-shaft has a gear 14 outside of the box, which
engages à like gear 15 on a plug-pin 16, fitted to turn in a bearing in the box
above the chuck-shaft. Connecting the geared end of this plug is a flexible
shaft 17, which extends down through an opening in the arm 10 and connects
with the upper end of a shaft JS, Figs. 5-6, loosely mounted within the tubular
shaft 7, whereby the rotation of said shaft 18 drives the chuck-shaft and rotates
the gathering instrument. The provision for rotating the vertical shaft 18 is seen
in Figs. 2, 5, 6 and 8, and consists of a gear 19, fixed on its lower end and engaging
with an equal gear 20 on a stud fixed in a bracket 21, secured to the base-plate 5
and carrying said gear 20 outside of the gear 19. This arrangement of the
gear renders it convenient to drive the flexible shaft by a sliding-gear connection
with a rotating line-shaft fixed in the frame. Such sliding-gear connection is
made by a bevel-gear 22, on the stud of the gear 20, and therefore carried
by the carriage so that said bevel-gear 22 will engage a bevel-pinion 23, Figs. 5
and 8, splined on the line-shaft 24, which being rotated from the clutch connections
thereby rotates the gathering instrument through its flexible-shaft connections.
As the carriage reciprocates the splined pinion 23 is caused by its bracket con-
nection Fig. 2, to slide upon the line-shaft, and, being rotated by it, rotates the
vertical shaft 18 by the intermediate gear, as stated.
The rotation of the gathering instrument by means of gear in which a flexible
shaft serves as an element to directly connect the said instrument with a rotating
line-shaft gives a compact and effective arrangement with a reciprocating carriage
and with a gathering instrument having a lateral swinging movement. The mount-
ing of the gear mechanism upon the carriage in a way to allow it to be actuated
by a sliding connection with the line-shaft allows the rotation of the gathering
instrument and of its laterally-swinging movements during the reciprocation of the
carriage. The mounting of the turn-table in concentric relation to the flexible-
shaft connections, as in Figs. 1 and 6, renders the rotation of the gathering instru-
ment and its lateral swing through a center conimon to both motions, and thereby
making the line-shaft the means for controlling and changing the speed of the
rotation of the gathering instrument.
The carriage is reciprocated by a crank movement which gives the advantage
of an easy stop, rendering it free from bump or jar and effecting a better delivery
action of the gathering instrument. This movement is by the crank 25 on the

page_text: shaft 26, mounted on the rear end frame, the said crank connecting by a rod 27 the
carriage; and determines the extent, the stopping, and the reversing of its move-
ment: This crank also serves as a lever having the function of a cam, whereby
the rotation of the gathering instrument and the movements of the carriage are
controlled. For this purpose the crank-lever extends on each side of its carrying-
shaft and has a cam on each arm part.
The line shaft 24 is mounted at the side of and parallel with the lower beam
and rotated by a sprocket wheel 28 on the clutch-driven shaft by a chain 29,
engaging a sprocket 30, Figs. 9, 15, 17, 18, 19, and 20, on shifting shaft 31,
mounted in the end frame. On this shifting shaft is fixed a gear 32, which
engages a gear 33 on the line-shaft, whereby it is rotated to cause the rotation
of the gathering instrument. This shifting shaft 31 also has a friction wheel 34,
and the shaft itself is adapted to have only sufficient endwise movement whereby
to engage said friction-wheel with accelerating gear to give a more rapid speed
to the shaft 24 and through it to the gathering instrument, as I will now state.
Referring to Fig. 17, the shifting shaft 31 is seen as being driven from the clutch-
shaft and is engaged with the line-shaft by the gear 32 83, which engagement is
maintained by a spring 43 on the outer end of the shifting shaft constantly pressing
it inward:
The accelerating-gear consists of a small friction-wheel 35, Figs. 1 and 9, on a
short shaft 36, mounted parallel to the line-shaft and arranged to engage the
larger friction-wheel near its periphery, while said short shaft 36, engages the
line-shaft by the gear 37 38, whereby the friction-wheels when in engagement
impart a comparatively fast rotation to the line-shaft, and through it imparts a
corresponding speed to the gathering instrument, for a purpose which I will
presently state. For the engagement of the friction-wheels the shifting shaft 3.1
is caused to have an outward movement, and this is effected by the rotation of the
crank-lever 25, which is provided with a cam-formed plate 39, Figs. 16, 20 and 21,
adapted to engage the upper end of the lever 40, pivoted in the frame and con-
meeting a pivoted arm 41, which engages the end of said shifting shaft 31 and
pushes it outward forcing and holding its friction-wheel 34 in engagement with
the accelerating friction-wheels 35, thereby quickly engaging the friction-gearing
and increasing the speed of the rotation of the gathering instrument at the proper
times in the operation of the machine, as in Figs. 15, & 19. The lever 40 has a
roll 42 to receive the action of the lever-cam 39, and the said roll is held in
position to receive the action of the cam by the spring 43 upon the shaft 31 and
the action of the latter upon the pivoted arm 41. So long therefore, as the cam-
plate 39 of the crank-lever is in engagement with the lever 40 the friction-gear
will be held in engagement; but when the said cam-plate in the revolution
of the crank passes its contact with said lever 40 then the spring 43 brings the
gear 32 83 into engagement and maintains it until the cam-lever again shifts the
gear. The cam is so formed with a curved and a flat part as to effect this operation,
as in Figs. 16 and 21.
Referring to Figs. 1 and 11, the shaft 26 of the crank cam-lever is preferably
arranged about midway between the track-rails, and below this shaft
is mounted the clutch-shaft, upon which is loosely fitted two equal
pulleys 44 45, with which a clutch 46 is caused to
engage as it is
shifted by the action of a cam 39 on the lever 40, as I will presently
state. These pulleys are continuously driven by belts from pulleys 47 48, Fig. H,
on the power-driven shaft, while a pinion 49 on the clutch-shaft engages a larger
gear 50 on the shaft of the crank cam-lever, whereby to cause its rotation. One of
the pulleys 48 on the power-driven shaft is comparatively small, the
object of which is to give a comparatively slow rotation to the pulley 45
when engaged with the clutch, and which when so engaged causes the
carriage to move slowly in advancing the gathering instrument while taking up
a charge.
The clutch-shifter 51, Figs. 12, 15 and 17, is controlled by a latch-bar 52,

page_text: pivotally connected at one end to the lower end of the lever 53, pivoted to the frame
and arranged to be engaged by the cam 39 on the crank-lever in a way to vibrate
said lever 53 and thereby actuate the clutch-shifter, the said latch-bar having a
notch 54, by which it is adapted to engage the upper end of the clutch-shifter.
A spring 551, Figs. 9, 18, and 17, connected to the clutch shifter 51, constantly
tends to engage and maintain the clutch in engagement with the pulley 44, while
a spring 101 constantly acts to place the latch-bar-connected lever 5 always in
position to receive the action of the cam-lever at each revolution of the latter. The
cam-plate 39 acts to pull the latch-bar 52 toward said cam-lever, and the throw of
the latch-bar is sufficient to cause the cluich to be engaged with either of the
pulleys 44 45 in operating the carriage and in rotating the gathering instrument
by the rotation of the crank cum-lever. The form of the cam 39, Figs. 16, 20
and 21, is such that its part which first engages the lever is so curved or formed to
vibrate the lever to give it the shifting action, while the flat surface part of
the cam acts to hold the clutch to its shifted position until the cam passes off the
lever-roll, when the latter will move into position to be again acted upon by the
cam in its revolution. In the same way the shifter-shaft is actuated and released.
In the construction shown the cam-plate 39 is formed to act upon the gear and
the clutch shifting levers at the same time and to release them at the same time:
but separate cams may be used to effect these operations. The other end of the
crank-lever, which is on the opposite side of the crank-shaft and diametrically in
line with the crank, is also provided with a cam 55, Fig. 20, which is arranged
and formed to engage the clutch-shifting bar 53 in the revolution of the crank;
but this shifting movement is effected by a throw of the cam 55 of less extent than
the throw of the cam 39. This lesser throw of the shifting lever acts to shift the
clutch only sufficient in extent to throw it out of engagement, as in Figs. 9, 15,
and 18, for stopping the carriage at the point of or just after it has reached its
full backward movement, which thereby will cause the swing of the gathering
instrument to be stopped to deliver the gather either into the press or at the
forming-block, according as the machine may be working in the manufacture of
pressed or of blown ware. So in like manner this end cam 55 is formed to act
upon the lever 40 with a throw only sufficient to put the gear 32 out of engagement
with the gear 33, and thereby stop the rotation of the gathering-iron at the time
the glass is being dropped into the press. It is therefore at the limit of the back-
ward movement of the carriage-actuating crank that the latch-bar is moved so
as to put the cluich out of gear with the drive-pulleys to stop the cotation of the
line-shaft to stop the rotation of the gathering-iron. This action of the end cam in
disengaging the gear 233 does not give sufficient movement to the shaft 31 to
put its friction-wheel 34 in gear. It will be understood that the gear-shifting
shaft 31 is continuously driven by the sprocket 28, being fixed to the pulley, which
is continuously driven.
It will be seen from the foregoing that the line-shaft is driven at different
speeds of rotation one speed being comparatively slow, given by the gear 31 32
at the time the gathering instrument is being swung out to deliver the gather,
and thereby prevent the glass from being thrown off, as would be liable under rapid
rotation. The other and greater speed of the line-shaft is given by the friction-gear
at the time the gathering instrument is gathering the glass quickly around the
enlarged end of the gathering instrument. This speed is changed to a slower
rate as soon as said instrument commences its ascent with the gather to prevent the
flying off of the gather.
The gathering instrument is caused to have a lateral swinging movement to carry
the gather either to a molding-press 56 or to a forming-block 57, at the side of the
machine and for returning to the melting chamber to repeat the operation of
gathering. The outward-swinging movement of the gathering instrument com-
mences as it clears the chamber in the outward movement of the carriage and is
effected and controlled by the reciprocation of the carriage and means which I
will now describe.

page_text: Referring to Figs. 5, 6 and 9, the tubular shaft 7. depending from the turn-
iable S, has a horizontal arm 58, (shown in dotted lines in Figs. 9 and 14) adapted
to engage a roll 59, adjustably fixed on the lower carriage-rail and to act in
engagement with said roll in such manner as to cause the sail shaft 7 to be turned
in its bearings, and thereby swing the turn-table and its gathering instrument
outward as the carriage moves back. The forward movement of the carriage causes
a reverse action of the said arm 58 to swing the gathering instrument inward
in position to again enter the chamber. As shown, this arm is of open slotted
form, so as to receive the roll 59 as the carriage moves back and
to leave the roll as the carriage moves forward. It stands obliquely
rearward when the carriage is moving forward, and as its rearward movement
brings the arm into engagement with the roll the arm is swung around toward the
front, the extent of its swing being governed by the position of the roll, which
is set to suit the extent of the movement of the carriage for the work
to be done at the press or the block. In its Tateral swinging
movements the swing end of the carrier for the gathering instrument is supported
by a ledge or way G, fixed to and extending out from the side of the carriage,
preferably curved, forming a track on which the carrier swings and being for this
purpose provided with roll 61, Figs. and 13, for easy travel. This track has,
preferably, a downward incline and a wedge 62 on its lower end placed so that
the carrier-roll will ride upon it and drop off with a sudden fall at the limit of the
swing movement of the gathering-iron when the glass is to be dropped off into the
press. This dropping off the wedge gives the glass a sudden jar and renders its
fall from the iron more certain. At this time the carriage and the gathering-
iron are without movement, and it will be understood that this dropping off of the
glass is only in the operation of the machine in the manufacture of pressed ware
and that in such operation the gathering-iron has a swing of considerable extent
in working with the press-mold, so that by the time the iron reaches the press
the glass will hang from the iron for free separation. The track terminates in a
concave 63, into which the carrier-roll drops from the wedge, which is beveled at
its free end to allow the carrier-roll to ride up over it in the return swing of the
gathering-iron. The pivoted arm 10 carries the gathering instrument in
horizontal position normally, as in Fig. 1, and for this purpose the said carrier
at its swing end is supported upon a shelf 64, Fig. 7, on which the roll 61 of the
carrier rests and which is suspended by a spring 65, secured to the front end of
the carrier by a rod 66, adjustably connecting a bracket 67 on the carriage. The
adjustment of the tension of this spring gives the proper force for raising the swing
end of the carrier for the gathering instrument and for supporting it in horizontal
position. The shelf 64 gives the advantage of a level way, as in Fig. 7, to form a
junction with the track, so that the roll 61 of the swing-carrier 10 passes easily
from the shelf to the track and from the latter to the shelf.
1
A guide-stem 68, depending from the shelf, passes through a guide 69, fixed to
the carriage and connects with a lever device mounted on a depending bracket
at the under side of the carriage, whereby the shelf is pulled down to effect the
dipping of the gatherer in its gathering function. This lever device consists of
two parts, one part 70 of which stands forward and is adapted to engage and
pull down the guide-stem 68 and its connected shelf against the tension of the
suspending-spring, as in Fig. 4. The other lever part 71 swings down and has a
projection or lug 72, on its pivoted end adapted to engage the forward-standing
lever part 70 in a way to depress it and its connected shelf. The guide 69 for
the shelf-stem serves to limit the ascent of the shelf in bringing the gathering
instrument to a horizontal position, as in Fig. 1. A fixed incline mounted, in a
hanger depending from the lower rail serves to actuate this lever device. The
incline is of approximately inverted V-form, one part 73 standing rearward and
the other part 74 standing frontward. The part 73 is arranged to receive and
engage the swing end of the lever part 71 as the carriage moves forward to carry

page_text: the gathering instrument into the chamber as the roll end of said lever part rides
up the incline. It is thereby swung back, causing its lug 72 to engage and press
down the lever part. 70, engaging the shelf stem, thereby pulling the shelf down,
the swing-arm 10 by its weight thereby falling with it and giving a dipping
descent to the gathering instrument only sufficient for a skimming action to gather
a charge, during which the movement of the carriage is comparatively slow,
while the gathering instrument has a rapid rotation. The extent of this dipping
is governed by vertically adjusting the incline 73 to give a partial immersion to
the gatherer, and I prefer to make this adjustment by a pulley 75, mounted so as
to, engage a screw-stem. 76, which carries the incline, in a way that a cord 77,
connecting said pulley and under the control of the attendant, will turn the pulley
to raise or to lower the incline, and thereby regulate with exactness the dipping of
the gatherer. This provision gives the advantage of setting the gatherer as may
become necessary to suit any varying level of the glass; but it is the intention
that the glass in the working chamber shall be kept at a uniform level. The
highest point of the incline is the limit of the immersion, and the lever device
having passed this point the swing lever part 71 descends the other side of the
incline and, dropping off, releases said lever device; the shelf meantime gradually
rising during the travel of the lever over its releasing incline and, dropping
therefrom, allows the gathering instrument to resume its horizontal position. In
dropping off the incline the lever hangs free to ride back out of engagement with
the shelf connecting the lever part during the backward movement of the carriage.
It will be understood that the gathering instrument is continuously rotated
while advancing to gather a quota of glass to hold it while being moved out of and
away from the chamber and while being swung to deliver the gather for work
and while delivering the gather.
The utilization of the crank for imparting reciprocating movements to the
carriage as the means for carrying provision for automatically controlling the
movements of the carriage and for automatically controlling the rotation of
the gathering instrument, and particularly as to the speed of such rotation, renders
the machine interchangeable for work with press-molds and with forming-blocks
the latter being set in place to receive the blowpipe when the machine is used
in the manufacture of blown ware. That part of the crank-arm which has the end
cams extends from the crank-shaft in a radial line with the crank, forms an exten-
sion of it, and rotates in the same plane, and the cams of both arms act within a
revolution of the crank to actuate the shifting-levers in the way stated.
I have shown the machine as organized for operating with plurality of
gatliering instruments arranged for identical and simultaneous movements at
opposite sides of the machine, and in such construction the turn-tables of the
gathering instruments are geared together at their mounting by like gears 78,
which cause the turn-tables to swing together, the swing of one produced as
described to the same extent swinging the other and the swing of both controlled
by the movements of the carriage, as stated. In like manner the rotation of one
of the gathering instruments serves io cause and to control the rotation of the
other, the rotation of one produced as described rotating the other with the same
speed. For this purpose the shaft IS, Fig. 5, which causes the rotation of one of
the gathering instruments, has a gear 79, engaging by an intermediate gear S1,
Fig. 10, an equal gear 80 on a short shaft 82, mounted in a tubular shaft 83 of
the turn-table at the other side of the carriage. The shafts 18 and 82 of these
two equal gears 79 80 are each connected to and drive the chuck of the separate
gathering instruments by means of a flexible shaft 17, each connecting by inter-
mediate gear 15, Fig. 3, with the chuck-shafts. The intermediate gear S1, which
engages the equal gear 79 80 of the chuck operating shafts, causes the gathering
instruments to rotate in opposite directions, as in Fig. 10.
In the forward movements of the carriage the gathering instruments; as
shown, are caused to swing in parallel relation and in such relation move into and

page_text: out of the melting-chamber in gathering each a charge of glass; but after leaving
the chamber and during the continued outward movement of the carriage the
gathering instruments are caused to swing out from the carriage to deliver the
gather to their respective working parts.
It will be understood that in working the machine in the manufacture of
pressed ware the gathering instrument is a solid iron 84, which remains in the
machine while gathering and dropping such gather into the molding-press, as in
Fig. 9.
When the machine is used for the manufacture of blown ware, a blowpipe 85
is substituted for the solid iron for operation with a forming-block, as in Figs. 13
and 14, and a separate blowpipe is used for each gather. For such work the
chuck has an air-tight fitting for the blowpipe and a suitable blow communication
therewith, whereby the glass is blown while being mechanically rotated and
formed upon the block. In changing the blowpipes provision is made for
supporting a blowpipe on the machine in readiness to take the place of the one
removed and to automatically deliver the pipe into the chuck as soon as the one
having the blown gather is removed. In this use of the machine the swing of the
pipe only sufficient to place the glass on the block near the side of the machine,
and while in this position the pipe is rapidly rotated in the machine, and while
the glass is being puffed or blown the pipe is carried in the machine, as in Figs. 13
and 14.
In Fig. 1 I have shown in dotted lines means whereby a blowpipe is supported
to be dropped and automatically inserted in the chuck, and in Figs. 13 and 14 I
have shown how this is done. On the upper track-beam, near its front end, is
secured a horizontal bracket SG, standing at the side and having at its end a
tilting device 87 hinged so as to tilt downward and toward the chuck and formed
so as to hold the gathering end of the pipe and act as a grooved runway for it. At
the required distance from this tilting device is mounted upon the track beam a
hanger device SS. Fig. 1, adapted to hold the blow end of the pipe. This hanger
device is pivoted in a vertical position, its lower end formed with rest-lip for
the pipe, its upper end serving as a handle, being held against a stop 89 by a
spring 90, which constantly pulls it against said stop to keep the rest-lip always
in position to hold the pipe. The tilting device is somewhat like a scoop or runway,
Fig. 14, and is provided with a counterweight 91, serving to more than balance
the pipe resting within said device. A stop acting against the bracket limits the
tilting of this device to an angle of about sixty degrees, as in Fig. 13. The hinge
of this tilting device is about vertically in line with the center of the forming-
block, the object being to deliver the pipe into the chuck at the time the finished
blowpipe is removed and while the carriage is standing at the limit of its rearward
movement and while the blowpipe is still rotating. The delivery and placing
of the pipe in the chuck, Fig. 3, are effected as follows: The rest-lip is tripped,
letting the end of the pipe drop into a guide rest 93, the gathering end of said
pipe resting in the tilting device 87. The blow end of the pipe falling first will
cause it to tilt the weighted device, so that the gathering end of the pipe will
slide down upon it, while the blow end of the pipe, having fallen into a concave
guide-rest 93, secured upon the swing-arm 10 in front of the chuck, serves to
support and guide the end of the pipe as it is driven into the chuck by the action
of its gathering end as it slides down the inclined grooved face of the tilting
device, the inclined position of which acts to shove or slide the pipe as it falls
fully in place in the chuck, where it is held from turning by the screws, the same
as the solid iron. The pipe is thus almost instantly dropped and automatically
chucked, so that the carriage is started for another gathering almost at the very
time the blowpipe is removed from the chuck, because at the time of removing
a pipe another is placed on the machine just where it can fall and he pushed
into the place of the one removed. In this charge the attendant uses one hand
to remove the finished blowpipe and his other hand to place another pipe on its

page_text: hanger and tilting device to be dropped and chucked. In this operation the blow-
pipe continues to rotate. The pipe having been delivered and chucked, the tilting
device is caused to resume its normal position, Fig. 1, to receive another pipe.
Referring to Fig. 3, the chuck-shaft 12 is seen hollow and is fitted with a rubber
packing-tube 94, into which the blowpipe is driven or pushed to provide an air-
tight joint. At the geared end the chuck-shaft has a "puff-tube"95, which opens
into the packing-tube and which at its outer end has an orifice 96, which by a
suitable mouthpiece, which, as shown, is like the mouthpiece of a speaking-tube,
projecting through an opening in the cheek 9 of the turn-table, Figs. 1, 3, and 6,
enables the attendant to blow or puff the glass while being formed upon the
block. The mouthpiece connecting tube 95 is fitted freely within the chuck-shaft,
and thereby forms a non-rotating connection with the rotating blowpipe, it being
understood that the glass is "puffed" or blown only when the pipe places it on
the block. In Fig. 6 this mouthpiece is seen as a projection on the side of the
cheek 9 of the turn-table and is dotted through said cheek and crosses to its con-
nection with the orifice 96 in the puff-tube, (seen in Fig, 3,) so that the mouth-
piece in the cheek 9 and the orifice in the puff-tube are connected by the short
flexible tube. A spring 98, Fig. 3, acting on the outer end of the puff-tube.
serves to keep it under tight fit in the chuck-shaft to prevent escape of air.
A round table 57, is provided with a number of forming-blocks 99 of different
sizes and which contain water into which the glass is rolled in the operation of
puffing. The round table can be adjusted vertically to suit the placing of the
gather into the block and the table can be turned to bring different blocks into
use. The swing of the pipe to the block is about eighteen inches, which is con-
trolled by setting the roll 59 so as to engage the turn-table arm 58 at the proper
time and point in the outward movement of the carriage. The farther away the
roll is set, the greater will be the extent of the outward swing of the turn-table
and of course the gathering instrument. The track or way on, which the swing
is made is of course suited for such movement of the blow-pipe, so that it will be
delivered without undue jar or fall at the block.
For accelerating the rotation of the pipe at the block, the end cam 55 of the
crank lever is supplemented by a cam-plate 100, Figs. 15 and 16, the function of
which is to act upon the lever 40, and through it the shifting shaft 31, to engage
the friction-gear with the line-shaft. This increased speed is advantageous in
blocking the glass and facilitates its finish on the block, and the cam-plate 100 is
added only when the blowpipe is in use. This added cam has the same form as the
cam 55 and is merely fitted upon its face, as in Figs. 15 and 16, to engage the
friction-gear to give increased speed to the blow-pipe when operating at the form-
ing-block under the accelerated speed of the friction gear.
In the multiple arrangement of the gathering instruments they are mounted
alike on opposite sides of the carriage and the provisions for using one' are
identical with those for using the other whether the operation be for the manu-
facture of pressed or for blown ware, and of course this requires an attendant for
the work at each side of the machine.
In the operation of the machine it will be understood that the band from the
power-driven pulley 47 constantly drives the loose clutch-pulley 44 on the clutch
shaft. and by means of the spocket-chain 29 said pulley drives the shifting
pulley-shaft 31, because said pulley 44 has fixed thereto a sprocket-wheel of said
chain that the loose-clutch pulley 45, also on the clutcli-shaft, has a slower
rotation than the pulley 44. because it is driven by the comparatively small
power-driven pulley 48, and that the crank-shaft is driven from the clutch-shaft,
as in Fig. 11, and that therefore the engagement of the clutch with the loose
pulley 44 will give a comparatively rapid movement to the crank-shaft, and hence
to the carriage. From this it will be seen that the shifting of the clutch will give
a slow or a rapid rotation to the crank to reciprocate the carriage both fast and
slow for purposes suited to different stages of the work and that these different

page_text: speeds are automatically effected and controlled by cams carried by the crank-
shaft and adapted to actuate a clutch-bar, by which the clutch is shifted from
engagement with the pulley 44 and engaged with the other pulley 45. For
this purpose the latch-bar through the lever 53 is positively moved by the cam 39,
Fig. 12, while a spring 101, Fig. 12, acts to return said lever to its position to be
again engaged by said cam; but in this movement of the lateli-bar it is first
disengaged from the clutch-shifter 51 by being lifted by the attendant, when
the connected shifter-spring 55 will shift the clutch from the pulley 45 to the
pulley 44. As the latch-bar rests freely upon the clutch-shifter 51, as in Fig. 12,
and slides upon it in returning the lever 53 to its normal position, the notch
of the latch-bar will again by its weight engage the clutch-shifter in readiness to
again shift the clutch by the action of the cam in the rotation of the crank.
That the movements and speed of the carriage and the rotation and speed of the
gathering-blowpipe may be more clearly understood as produced by the revolution
of the crank-shaft cams the following is the order step by step of such movements
of the machine operating with the blowpipe for gathering glass for blown ware
Referring to Figs. 1 and 20, the carriage will be understood as moving forward
under the fast speed of the drive-pulley 44, with the crank 25 descending to
engage its cam 39 with the shifting-levers. The gathering-blowpipe on entering
the chamber is caused to dip, thereby partially immersing its gathering end
into the glass and at the time the said cam 39 is brought into engagement with
the lever 53 causing it to shift the clutch from the drive-pulley 44 to the drive-
pulley 45 and thereby slow the movement of the carriage while the end of the pipe
is skimming the glass. At the same time the cam 39 has engaged the lever 40,
causing it in shift the shaft 31 to engage the friction-gear 34 35, and thereby
accelerate the rotation of the line-shaft 24 to rapidly rotate the
blowpipe while it is gathering the glass. In the top view. Fig. 19,
this cam is seen as descending and engaging the two levers at the same time
and the cam leaves the levers at the same time, and while engaged with them
the said cam holds the shifted parts in their positions long enough to effect the
purpose of shifting the clutch and the gear. The cam 39 therefore gives a slow
forward movement and a rapid rotation to the blowpipe while it is in the glass;
but as soon as this cam passes its engagement with the shifting-levers and the
crank passes its dead-center the clutch is again quickly engaged with the fast
pulley 44, as in Fig. 17, and the shaft 31 is again engaged with the line-shaft.
causing the blowpipe to rotate slowly, this while it is rising and swinging out to
the forming-block: otherwise the glass would tend to be thrown off by centrifugal
force. In the meantime the releasing of the clutch-lever 53 causes the clutch to
again engage the pulley 44 to give a rapid outward movement to the carriage
to swing out and bring the blowpipe as quickly as possible to the forming-block,
this speed being necessary to carry the glass to the forming-block with the least
loss of time. At the time or just before the crank reaches its other dead-center
in its rotation and about as the blowpipe reaches the forming-block the end
cams 55 and 100 are brought into engagement with the shifting-levers, as in
Fig. 15, to stop the movement of the carriage and again rapidly rotate the pipe.
In this engagement the cam 55 is caused to shift the lever 5 only to an extent
that will place the clutch out of engagement with the drive-pulley 44, and thereby
stop the movement of the carriage. At the same time the cam 100 engages the
lever 40, and thereby shifts the shaft 31 and engages the friction-gear to rapidly
rotate the blowpipe in blocking the glass at the forming-block. In this action
of the end cams they engage the shifting-levers at the same time and leave them
at the same time, and while so engaged hold the shifted parts in their positions
long enough to effect the purpose of shifting the clutch and the gear. While
the blowpipe is being rotated at the block, the attendant places, his mouth at the
low-tube 97 and puffs the glass while it is being rotated. The placing of the
blow-tube in the turn-table not only renders it convenient for puffing while being

page_text: rotated in the machine, but by making the tube which forms the blow-orifice
flexible its connection with the blowpipe through the check of the turn-table
allows the blowpipe to swing vertically on its pivotal connection with the check.
The glass having been sufficiently puffed the blowpipe is removed and another
pipe put in its place. The attendant then raises the latch-bar 52, releasing the
clutch-shifter 51, which by its spring 551 again engages the clutch with the
pulley 44, and the carriage is quickly driven forward, returning the blowpipe in
position again to enter the chamber to repeat the operation. In releasing the
clutch to make this shift the latch-bar by its notch is again automatically engaged
with the said clutch-shifter 51 by means of the spring 101 to again shift the
clutch.
From the foregoing it will be seen that the blow-pipe has three separate and
distinct degrees of speed in its rotation--a rapid speed while gathering the glass,
a slow speed while swinging out to the block, and, again, its rapid speed, while
the glass is being puffed or blocked.
Referring to the provision for automatically chucking the blowpipe by dropping
it from hangers, one of which forms a tilting incline or way which acts to push the
pipe endwise into the chuck on being dropped in front of the latter, it is important
to note that the heaviest or gathering end of the pipe occupies a position near the
hinge of the tilting incline, so that the weight of the pipe will not act to tilt the
incline until the blow end of the pipe has been released and has fallen into and
rests in the guide which receives it. This provision for automatically delivering a
suspended blowpipe from its suspending-hangers on the frame of the machine
into the chuck while it is without movement saves the expense of an attendant
to handle and secure the pipe in the machine. In the delivery fall of the pipe the
jar it receives by its liberated end striking upon the guide-rest will start the tilting
of the hanger, and thereby the forward movement of the pipe upon the tilting
hanger, and slide it into the chuck as the pipe slides down with and upon the
hanger.
It will be understood that many of the devices are not essential to the several
features of my invention, separately considered. This will be indicated in the
concluding claims, as in any given claim the omission of an element or the
omission of reference to the particular features of elements mentioned is intended
to be a formal declaration of the fact that the omitted elements or features are not
essential to the invention therein covered. As a matter of fact, however, while I
have shown and described the machine in its relation to the blowpipe and its
holder, yet it is apparent that the machine is complete in its organization without
the presence of the blowpipe in its holder.
