page_text: A cap 6, is provided for the upper end of the column B, and said cap is perforated
to permit the passage therethrough of the bolt 4. Said cap affords an abutment for
the hand-wheel to act against when it is turned to raise the head C, and the parts of
the machine depending therefrom.
The end of said arm C2, is bifurcated horizontally, and in each part, a and b, of said
bifurcated end a bearing is provided to receive the vertical main-shaft D.
The said main-shaft of the machine is supported in bearings in the ends a and b, of
the arm C, by a collar 7, secured to its upper end, said collar bearing against the top
of the part a, as shown.
Said shaft D, has a free rotary movement in its bearings in the end of said arm C²,
means for imparting said movement consisting of a bevel-gear 8, secured to said shaft
between said parts a and b, of the arm C2, by a set-screw in the hub thereof, or other
suitable manner, and a bevel-gear S", in mesh therewith; said bevel-gear being secured
to the end of a shaft E, suitably supported in a bearing E', within the head C, as shown
in Figure 1.
Said shaft passes centrally through the slot 2, of column B, in one side thereof, and
through a slot E³, in the opposite side of said column; on the end of said shaft
projecting through said column, a pulley F, is secured which, by a suitable belt, is
rotated and by means of the mechanism just described rotates the main-shaft D, and
the various parts secured thereto.
The lower extremity of said shaft D, has a bearing in a long sleeve 9, cast on the
base A, which is of suitable length to permit of more or less vertical movement of
said shaft therein.
. Close up against the under side of the lower end of the part b, of the arm C³,
is secured to the shaft D, by set-screws or other suitable means, the upper blow-
iron spider S, and at a suitable distance below said spider S, is the lower blow-iron
spider S', secured to the shaft D, in the same manner as is spider S.
Said two spiders have each four arms and a central hub cast thereon, and are so
secured to said shaft that the arms of each are in the same vertical plane, and each
arm of both spiders is provided with means for holding a blow-iron in a perpendicular
position for rotational movement therein, to be described further on.
In the face of the part b, of the arm C, lying next to the hub of the spider S,
is provided, (see Figure 6,) an aunular channel 11, therein, passing about three-
quarters of the way around said part, one end thereof connecting with a hollow-arm
or conduit 12, preferably cast integral with said part b.
The outer end of said arm 12, is screw-threaded to receive a suitable coupling for a
piece of hose 13, or other flexible conduit, (sce Figure 4,) which may be connected to
any suitable mechanism for supplying air under pressure.
The hub 10, of the spider S, and its four arms, is provided with air-passages 15,
therein, which passages, horizontally disposed in the arms of the said spider S, turn
upward through the hub 10, and their openings, (see Figure 5) coincide with the
opening of the channel 11, in the face of part b, of the arm (2.
The said spider S, as has been stated, is secured to the shaft D, the upper end
of the hub 10, thereof and the lower end of the part 6, of the arm C, being finished
off in such manner as will assure a substantially air-tight joint.
In each one of said vertical portions of the air-passages 15, in the hub of spider S,
a plug-valve 16, is located whereby the passage of air therethrough may be controlled
at will.
The stems of said valve 16, project outwardly at right angles to the main-shaft D,
and are provided with spiral springs 17, arranged to close the valves after they have
been turned to permit the passage of air therethrough.
Said valves are operated for that purpose by a cam-arın 18, fixed on the end of the
valve-stem, the upwardly projecting ends of which arms lie in such position that by
the rotation of the spider S, with its shaft D, said arms 18, are carried under and
engage with a cam-plato 19, concentric with said shaft D. The length of said
cam-plate 19, determines the length of time said valves shall remain open.
Said arms, as soon as they pass out from under the end of the cam-plate 19, are

page_text: operated by the said spring 17, to close them, until they again engage said cam-plate
by the continued rotation of the spider on its shaft. Thus the air-passages in each
arm of the spider S, are automatically and consecutively opened and closed during
a part of its revolution.
The said cam-plate is adjustable vertically and supported by means of the screws 20,
(see Figure 1), passing through the semi-circular flange 21, cast on the side of the
part of the arm C, and by adjusting said cam-plate in any desired degree of
inclination relative to the plane of rotation of the spider S, a gradually increasing or
diminishing blast of air may be delivered through the passages 15, in the arms
of the said spider. If desired, the surface of said cam-plate which said arms 18,
engage with may be given such configuration as will admit to the air-passages 15, a
blast of air of any desired degree of pressure and duration.
The ends of the arms of the spider S, are closed and an outlet for the air is
provided by a perforation made near the ends of said arms and in the under side
thereof for the reception of the chucks 22, (see Figure 4), which chucks receive and
impart rotary movements to the blow-irons 23.
Said chucks 22, (the lower ends of which are enlarged, see Figure 7), are provided
with an air-passage 24, the lower end of which terminates in a funnel-shaped
mouth having a pin 25, therein for engaging with one of the several holes 26, in
the end of the mouth-piece 27, of a blow-iron, and whereby a positive engagement
is made between said chuck and said blow-iron for the rotation of the latter.
The end of the chuck 22, lying within the air-passage 15, is counter-bored, as
shown in Figure 7, to receive a spiral spring 24, one end of which, bearing against
the bottom of said counter-bore and the other against the upper wall of said air-passage,
serves to maintain a contact between the end of the blow-iron and the funnel-shaped
mouth of the lower end of the chuck.
Means for holding said blow-iron in the arms of the spider S', consist of two
spring-actuated fingers o, o, (see Figure 1B) having outwardly flaring ends to permit
the easy insertion of the blow-iron into the forked end of the spider-arms. Said
springs are of sufficient strength to always hold the iron in proper position, but not
sufficiently strong to prevent the withdrawal of said blow-iron from the grasp of said
fingers by the hand of the operator.
Means for rotating the said blow-iron consist of a groove: or other suitable
pulley 28, fixed to the said chuck 22, and connected by a suitable belt with a pulley 29,
supported on shafts 30, rotatably supported on the side of the arms of the spider S,
near the hub thereof, which shafts are provided on their upper ends with tapered
friction-pulleys 31, adapted to engage the similarly tapered edge of the flange 21,
above referred to, cast on the side of the part b, of the arm C².
A bracket d, is secured to the extremity of each of the arms of the spider having
an arm thereon extending back under the arm of the spider and parallel thereto,
and at such a distance therefrom as permits the location of the pulley 28, between
the underside of the arm of the spider and the upper side of the arm of the bracket,
and said bracket-arın is provided with a hole for receiving the chuck 22.
A second bracket f, is secured to the underside of the arms of the spider having an
arm extending under the end of the mouth of the chuck 22, to hold said chuck in
position against the thrust of the spring 24".
Said pulley 28, engages with the shank of the chuck 22, by a spline-and-groove
connection, whereby the chuck is permitted to move vertically through said pulley
when a blow-iron is pressed up against the lower end thereof for operative engagement
therewith, and said pulley is secured against any vertical movement by its position
between the bracket d, and the arm of the spider S.
The beforementioned flange 21, is so located that the contact therewith of the
frictional pulleys 31, is coincident with the opening of the air passages in
the arms of the spider, as above described, and said contact is also of about the
same duration as the length of time said valves are open for the passage of air
therethrough.
If it is desired at any time to stop the axial rotation of the blow-irons 23, and use

page_text: the machine without imparting rotation to said blow-irons, the pulleys 31 may be
dropped on their shafts 30, whereby they will escape contact with the flange 21,
during the rotation of the spider S.
As the larger part of the articles made with this machine require the use of sectional
paste-molds, means for automatically opening and closing them, and for automatically
dipping them in water between the times of such opening and closing for cooling
them and for keeping the paste lining thereof moist, are provided as follows:
Suitably secured, by set-screws or otherwise, to the main-shaft D, is a hub H,
having four arms thereon h. The lower end of said hub bears on the top of the long
sleeve or bearing 9. The extremities of the arms h, are slotted to receive the ends
of the mold-carriers J, which are hinged, by a pin 32, between the ends of the slotted
arms h, whereby they are permitted, at proper times, to have a reciprocatory motion
in a vertical plane, downwardly from a horizontal to a perpendicular position, as shown
in Figures 1, 3, and 8.
Said mold-carriers J, are provided with a downwardly projecting arm J', near their
point of connection with the arms h, which arms have on the end thereof a bearing
roll 33, for engagement, during a certain portion of the revolution of the main-shaft,
with a cam 34, properly supported on said sleeve 9, and concentric with the shaft D,
whereby, when said mold-carriers reach a certain point in their revolution each one
of them being released from its means of support in a horizontal position at the
moment the bearing roll 33 engages with one end of the cam 34, said mold-carrier is,
by the latter, guided downward on the easy spiral curve of said cam from the
horizontal to the perpendicular position, and from the perpendicular to the horizontal
position again by the continuous rotation of the main-shaft D.
At that point in the revolution of the molds 35, where this dip of the mold-
carrier takes place is located the water-tank L, of suitable dimensions, to
receive said mold-carriers and molds. Said tank is not attached to the base of the
machine.
By referring to Figures 1, 3, and 8, of the drawings, it will be seen that said
mold-carriers J, are held in a horizontal position on the arm h, during that portion
of their revolution when they are not engaged with the cam 34, by a latch 36, having
a horizontal movement in a slot cut in the arms h, near the hub H, and which hub
has a hole bored into a boss 37, thereon to receive a stem 38, on said latch between
the end of which stem and the bottom of the hole in which it is located is a spiral
spring whose compression tends to keep said latch pressing outwardly against the end
of that part of the mold-carrier between the slotted arms h; a lip 39, on said latch
overhanging and engaging the upper edge of the end of the mold-carrier and
maintaining it in a horizontal position.
Referring to Figure 3, it is seen that an arm 40, is secured to the long sleeve or
bearing 9, the end of which arm has an upturned wedge-point thereon so located as
to engage the wedge-shaped portion of the latch 36, which projects below the under
side of the arm, which engagement takes place just as the bearing-roll 33, runs onto
the point of the surface-cam, all shown in said Figure 3, and in plan view in said
Figure 8, assuming that said mold carriers are revolving from right to left.
Said latch is held out of engagement with the end of the mold-carrier until said
carrier has dropped sufficiently to raise the said end of the carrier above the point of
the lip 39, on the said latch.
Immediately following the disengagement of the said latch, (see Figures 8 and 9)
the trigger 41, located on the under side of the mold-carrier J, and pivotally
secured thereto by a screw 42, is disengaged from the crank-arm 43, by the pin 44,
thereon striking against the post 45, (see Figure 3,) secured to the base A, leaving
the latter free to move. Said trigger 41, when moved out of engagement with
said arm 43, compresses the spring 41, between its opposite end and a suitable
abutment provided therefor, which spring serves to return said trigger to an
engagement with the arm 43, when the mold closes.
Said crank-arm is secured to a vertical pin 43ª, supported in a suitable boss 46,

page_text: on one side of the mold-carrier and to its upper end is secured the crank-arm 47,
similar to said arm 43.
To the free end of said arm 47, two rods 48, extend to ears 49, on each half of the
molds 35, which molds are pivoted to the mold-carrier at m, (see Figure 8), and also
secured to said free end of arm 47, is one end of a spiral spring 50, whose opposite end
is secured to a pin in the end of the mold-carrier lying between the slotted ends of the
arms; said spring is under tension when the mold 35, is closed, and hence, as soon
as the trigger 41, is disengaged from the crank-arm 43, said spring 50, operates by its
contraction to open said mold 35, and at about the same time the pin 44, on said trigger,
disengages from the post 45, and the latch 36, from the arm 40, and by the continued
rotation of the mold-carriers said open mold, (following the path of the cam 34), is
carried down into the water-tank where it is cooled and has its paste lining moistened,
and then the bearing roll 33, encountering the opposite curve of the said cam, said mold
rises out of the water and when nearly at the end of its upward movement, towards the
horizontal position, it is automatically closed by the roll 51, on the end of the
crank-arm 43, encountering the suitably curved vertical cam 52, secured to the base A,
of the machine, whereby the crank-arm 43, is moved toward the outer end of the
mold-carrier, thus moving the crank-arm 47, in the same direction, and through the
operation of the rods 48, connecting said crank-arm and the two parts of the mold 35,
the latter is closed.
This movement is carried far enough to permit the notch in the trigger 41, to again
become engaged with the hook on the end of the arm 43, securely locking the parts
until such time as the trigger is again operated to release them.
Simultaneously with the locking of the two halves of the mold together, the latch 36,
again engages with the end of the mold-carrier as the latter resumes its borizontal
position, said latch being operated by the spring acting on the end of stem 38, of
said latch.
The blow-iron is removed with the finished article as said molds open to descend
into the water tank, and another blow-iron is inserted in proper position in the
spiders S and S¹, the upper end 27, thereof, entering the funnel mouth of the chuck 22,
and the lower end having a gathering of plastic glass thereon, being held in such
position by engagement with the chuck, as described, and with the retaining clips
in the ends of the arms of the spider S', that when the two halves of the mold 35,
come together in closing, by the means above described, said gathering of glass
and the end of said blow-iron will be enclosed by said mold in proper operative
position.
The operation of this machine is effected as follows:
As one of the molds rises out of the water-tank L, and before the bearing-roll 51,
on the end of the crank-arm 43, encounters the vertical cam 52, to close the mold,
a blow-iron having a fresh gathering of plastic glass is, by the operator, placed in
position in the spiders S and S'. The upper enlarged extremity 27, of the
blow-iron 23, is placed above the forked end of the bracket f, and forced back
into said fork, the lower beveled edge of the chuck 22, and the beveled top of
the part 27, of the said blow-iron, permitting said end 27 thereof to force upward the
said chuck against the action of the spring 24ª, which spring, when the end of the
blow-iron is centrally under said chuck, forces the latter down onto the beveled end of
the blow-iron and a slight turn of the blow-iron, by hand, is sufficient to cause the
pin 25, in the funnel-shaped mouth of the chuck to enter one of the holes 26, as
described.
Said blow-iron is then pushed in between the spring-clips illustrated in Figure 1ª,
in the end of the lower spider S', and the blow-iron is then securely held in a line
central with the mold 35, as the two parts of said mold close when they are locked,
which locking takes place substantially at the same time the mold-carrier reaches a
horizontal position and the lip 39, of the latch 36, is snapped over the end of the
mold-carrier, as described. Soon after these movements have taken place, the end of
the arm 18, on the stem of the valve 16, passes under the surface-cam 19, and the said

page_text: "
valve is operated to admit air under pressure from the constant supply maintained in
the channel 11, said air passing through said valve, the passage 15, in the arm of
spider S, and down through the passage 24, of the chuck 22, and from thence into the
upper end of the blow-iron.
Simultaneously, or nearly so with the opening of the valve 16, to admit air to the
blow-iron, the beveled friction pulley engages with the beveled edge of the flange 21
rotary movement being imparted to said pulley by such engagement; which movement
is transmitted through the pulley 29, and a suitable belt running on said pulley and
the pulley 28, secured as described to the chuck 22, which engages with the end of the
blow-iron and rotates the latter.
The article to be blown rotates in said mold under whatever pressure, either constant
or varying, which is required during substantially one-half of one revolution of the
molds, or from the time the arm J', of the mold-carrier runs off from one end of the
cam 34, until it engages with the other end thereof, just before which engagement
the air-valve is closed and the beveled friction pulley 31, becomes disengaged from the
flange 21, and upon the opening of the mold just before it begins its descent into the
water-tank I, the blow-iron is removed with the finished article on the end thereof,
such removal being accomplished by the operator grasping it and pulling it out from
between the spring-actuated clips on the spider S', and disengaging its upper end from
the chuck 22, in the same manner.
A glass-blowing machine constructed according to my invention ensures an easy and
rapid adjustment of the lower ends of the blow-irons to a set of molds of any height,
the driving mechanism and air-supplying devices and air-controlling devices and
blow-iron supports moving as one. The construction furthermore is simple and the
arrangement of the various elements thereof permits of easy access to all the working
parts, and by the use of the means herein described for rotating the blow irons, all jar
or vibration resulting from the use of gears, etc., is done away with and practically no
loss occurs from breakage during the operation of blowing.
For the purpose of adjusting the lower ends of the blow-irons, to molds of varying
heights, the set-screw in the hub H, to which the mold-carriers J, are hinged, as
described, is loosened so that the shaft D, may be moved vertically through said hub;
the new molds are then placed in position and secured on the mold-carrier and by the
hand-wheel 5, on the bolt 4, the shaft D, carrying the spiders S and S', and with them
the blow-irons, is adjusted to bring the ends of the blow-irons into proper operative
relations with the said molds, and the set-screw in the hub H, is again tightened
securing the said nold-carriers on said shaft.
