- a spring pressed detent I35 moves the latch to locking position.
- Safety devices individual to the decorating units are provided for preventing operation. of a screen cylinder C2 when there is no bottle or workpiece in the chucks and thereby preventing the screen from being moved forward.
- One such safety device is illustrated in Figs. 11 and 12. It includes a screen safety valve V which is operated by a rock arm I36 mounted to swing on a pivot I31 and having its free end in position to bear against the valve stem. The arm is normally held retracted by a coil spring I38, leaving the valve open for normal operation.

- valve V (Fig. 5) has been opened by the upward movement of the driving pin 33.
- the air pressure supplied to the valve V as just described shifts the valve and supplies air pressure beneath the piston of the motor C (Fig. 3) and thereby actuates the motor and causes it to raise the locking pin 38 out of engagement with the carriage I1.
- This upward movement of the motor piston' also causes the contact rod 48 connected to the piston rod to open the valve V.
- the valve is thus shifted .to supply air behind the motor piston 21 (Fig. 2), causing it to index the carriage, thereby carrying the bottle 13 from station I to decorating position at station 2.
- motor 0 also operates through the rod El to open the valve V as the motor piston is completing its V. This causes the motor C to lower its piston,
- the opening of the valve V as above noted, as the motor C is completing the carriage driving stroke, also admits air pressure through the pipe 2L0, 2 to the trip motor C causing it to operate the pawl 83, thus releasing the trip lever 8
- the opening of the valve V also admits air through a pipe 2 to the left-hand end of the valve V thereby shifting the latter into position to admit'air through pipes 2I5, the valves V and pipes 2 l6 to the screen motors C of the four decorating units.

The machine as shown, in general, comprises a machine base ID, a stationary center column l6 rising therefrom, a work-holding table or carriage ll including a hub extension ll (Fig. 3), mounted for rotation about the column l6, workholding units l8. (five being herein shown), mounted for rotation with the carriage ll, each said unit including a bottom chuck 19 for supporting a workpiece or bottle B and rotating it about its axis, and a neck chuck 20 movable vertically into and out of position for holding the bottle. The carriage I1 is rotated intermittently, step-by-step, by a piston motorC (Fig. 2) which operates carriage indexing mechanism as hereinafter described, to move each bottle or workpiece from a station I, at which it is placed on the machine by the operator, to decorating stations 2, 3, 4 and 5 at which are located decorating units 22 having a stationary mounting on the machine base. Each decorating unit comprises a screen 23 (Fig. 7) in a screen frame 24 supported on a screen'carrier 25'which is mounted for movement radially of the work table for moving the screen to and from decorating position, a squeegee 26 movable up and down by a piston motor 0 attached to the carrier 25, anda piston motor C for moving the carrier 25, all as more fully set forth hereinafter.
A more detailed description of the invention is as follows:
The motor C (Figs. 2 and 3) for indexing the carriage ll, includes a piston 21 and a piston rod 28 connected to a slide block 29 slidable in guideways 30 on the machine base. A link 31 connects the slide block to a rock arm 32 which is Journalled on the column I6. Means for effecting a driving connection between the rock 3 vided with sockets 34 or openings (Figs. 3, 11) spaced at intervals corresponding to the step rotations of the carriage. Coil springs 33 (Figs. 2 .and 5) are connected to the driving pin and apply an upward tension thereon for projecting same time to lock the carriage 11 in its indexed position by means of a locking pin 38 which is attached by a strap 39 to the piston rod for movement up and down with the rod, out of and into the sockets 34. The operation of the motor C is controlled by a lock valve V as hereinafter described. When the driving pin 33 has been lifted to enter a socket 34 as shown in Fig. 3, the indexing motor C operates to rotate the carriage the angular distance between the stations, namely, 72, thereby bringing the driving pin 33 and socket 34 into register with the locking pin 38. The motor C then operates to lower the piston rod 35, therebylocking the carriage and withdrawing the driving pin 33, permitting the return stroke of the motor piston 21 while the carriage is locked.
Attached to the slide block 29 (Fig. 2) is an arm 40 provided at its outer end with an opening through which a rod 4| extends. The ends of the rod are slidably mounted in stationary bearings 42. The lengthwise movement of the rod is limited by collars 43 fixed to the rod. The function of the rod is to operate pilot valves V and V (see Fig. 13). A valve operating rocker 44, mounted to rock on a pivot pin 45, has a slot and pin connection 46 with the rod 4!. When the motor piston 21 moves forward for indexing the carriage, the arm 4!! slides along the rod 4! and during the final movement of the piston, engages the collar 43 and thereby moves the rod 4i to the right, against theforce of a coil spring 41 housed in the bearing 42, thus swinging the rocker 44 (Fig. 13) and operating the valve V When the piston 21 commences its return movement the,
arm 46 is withdrawn from the collar 43 permitting rod 4| to be moved to a central position by the spring 41, thus releasing the valve V As the piston 21 completes its return movement, the arm 40 engages the other collar 43 and moves the rod 41 to the left, thereby causing the rocker 44 to actuate the pilot valve V*.
The piston rod 35 (Figs. 3 and 13) has attached thereto an arm 48 carrying a contact rod 49 between and in line with the valve stems of upper and lower pilot valves V and V which have a stationary mounting. When the motor C operates to lift the piston rod 35 and the locking pin 38 to permit indexing of the carriage, the valve V is opened by the contact pin 49. When the piston rod 35 is lowered at the completion of theindexing movement, to lock the carriage and release the driving arm, the valve V is closed and the valve V opened by the contact pin 49.
Referring to Fig. 5, a pilot valve V is arranged to be opened by the driving pin 33 when the latter is moved upward by the springs 33 into driving position. Operating connections between the valve and driving pin include a rocker 50 pivoted at 59 said rocker having onc' arm projecting over a lug 50 on the driving pin and an arm extending into position to engage the valve stem. The work-holding units, as before noted, each comprises a lower chuck l9 and an upper chuck 25. The chuck l9 has attached thereto a depending stem 50 (Figs. 3 and 7) which is journalled for rotation in bearings 51 in the carriage l1. Attached to the lower end of the stem 50 is a spur gear 52. A stationary segmental gear 53 is attached by screws 54 (Fig. 4) to a cam plate 55 having a fixed mounting on the column IS. The gears 52 on chuck spindles intermesh with the gear teeth on the stationary gear 53 so that the rotation of the carriage lT causes the gears 52 to rotate the chucks I9 about their axes.
\Vhile the gears 52 are out of mesh with the gear 53, their rotative position is controlled by cam tracks 55 and 57 formed on the cam plate 55. Eachgear 52 has mounted on its lower side, cam follower rolls 58- and 59 adapted to run respectively in the tracks 56 and 51. The carriage l'l rotates in a clockwise direction, so that the gears 52 travel clockwise around the center column and also are rotated clockwise about their own axes. The gears 52 and 53 are so proportioned that each gear 52, while in mesh with the gear 53, is rotated about its own axis during one step rotation of the carriage, so that the four faces of a square bottle are presented to the four decorating units in succession at the stations 2, 3, 4 and 5. As a gear 52 moves forward between stations 4 and 5, the cam follower roll 59 enters the cam track 51, which is shaped to correspond with the path of movement which the roll 59 must follow while the gear 52 is still in mesh with the stationary gear 53. By the time the gear 52 reaches station 5, it is unmeshed from the stationary gear and the other cam roll 58 is at the entrance of the stationary cam track 56. The cam track 5! serves to steady the gear 52 preventing vibration or displacement as the gears unmesh and control of the rotative position of gear 52 is transferred to cam track 55.
From this point on, the rotative position of the gear 52 in respect to its axis is controlled by the cam track 56 until station I is reached at which the workpiece is removed from the chucks. The track 56 is concentric with the axis of the carriage through the greater portion of its length, thus holding the gear against rotation about its axis during its travel from station 5 to station I. When the gear 52 advances from station I, an outwardly directed portion 56 of cam track 56 starts rotation of the gear about its axis and controls its rotation until it meshes with the stationary gear 53 by which it is further rotated so that when it reaches the decorating station 2, it is again in position for holding a workpiece in register with the decorating unit. That is to say, the total rotative movement of the gear 52 and chuck carried thereby during the travel from station 5 around to station 2 is through 90".
The upper chucks 26, referred to herein as the neck chucks, are mounted each to rotate freely about its axis in an arm 6| secured to and extending radially outward from a chuck holder 62 mounted for up-and-down movement on the hub portion l'l of the carriage. The chuck is removably held in position by a spring pressed pin 63 which engages an annular recess in the chuck spindle. The carriage hub I1 is formed with vertical ribs 64 (Figs. 1 and 11) which together with removable keeper plates or strips 65 and 66 secured thereto, provide guideways for the chuck holder 62. An arm 61 attached to and extending outwardly from a rib 69 on the strip 99, is formed at its outer end with divergent guiding fingers68 for engaging the neck portion of a bottle B as the latter is placed by the operator on the bottom chuck, and serves to center and support the bottle while the neck chuck is being moved downward to holding position. The arm 61 is adjustable up and down on the strip 66.
The neck chuck 20 is yleldingly held in its lowered position by a coil spring II housed within the chuck holder 62 and held under compression between a. plug I2 threaded in the holder 62 and a stop I4 on the hub I1. The spring 1| is under compression. The neck chuck 20 is automatically raised by the piston motor .0 The motor piston 15 is moved upwardly by air pressure supplied as hereinafter described and is lowered by a coil spring 16 mounted in the motor cylinder. A piston rod 'II extending downwardly from the piston carries a collar 18 formed with a projection to engage beneath a shoulder I9 on the chuck holder 62, thereby providing a connection by which the chuck holder is lifted with the motor piston. This connection provides lost motion between the piston and the chuck holder so that the chuck is placed under the compressive force of the coil spring II, the connection also permitting the chuck to be lifted free of the bottle, independently of the motor.
A pilot valve V positioned behind the motor and mounted on the motor cylinder is opened by means of a rock arm 8 I pivoted at 82 on the head of the motor and having its free end projecting over the stem of the valve. With the parts in the position shown in Fig. 3, in which 'the motor piston I is in its lowered position. the rock arm 8 I is held down by a pawl or latch 83 pivotally connected to theupper end of the piston rod 11. The latch is tripped by a piston motor 0 referred to as the trip motor, comprising a piston 84 and piston rod 85. When air pressure is applied beward when air pressure is applied the piston. The screen carrier is returned or with drawn from the workpiece by a pair of coil springs I02 (Fig. 8) mounted in the member 90 and held under compression therein. Each spring bears against a slide block I03 to which is -attached a pin I 04 extending upward through a slot in the member 90 into an opening in the member 96.
The squeegee motor C comprises a cylinder I04 attached to the plate 95 and includes a piston and piston rod I05. the latter extending through an opening in the plate 95 and having attached thereto a slideblock I06 or head, mounted for up-and-down movement in the frame 94. The latter is substantially square in cross section and hollow or tubular in form as shown in Fig. 1 at the station 2. It is formed at its forward side with a vertical slot I01 and includes a removable plate I08 formed with a vertical slot I09.
An. arm III which carries the squeegee extends through the front slot I01 and is attached by pins I I2 to the slide block I08 which is forked to receive said arm. The arm I II is extended downwardly at its forward end and carries a pivot pin I I3 on which the squeegee is hung for swinging movement,
' squeegee 26 is removably held in. a holder f I4 hind the piston, it operates the latch 33 and releases the rock arm 8I permitting the valve V to open. The piston 84 is returned by a coil spring 86. The manner in which the valve V and the motor C control various operations of the machine will be described hereinafter.
A decorating unit will now be described. Referring to Figs. 6 to 9, the decorating unit comprises a stationary base member 90 which forms a slideway on which the screen carrier 25 is mounted for sliding movement to and from the decorating position. The base member 90 is mounted for vertical adjustment on a pair of posts 9I by means of adjusting screws 92. The
The screen 23 is of conventional construction and is provided with any desired decorating design or pattern. The squeegee 26 bears against the screen during both the up and down movement for applying the design to the workpiece. A supply of the decorating material is maintained in a pan I23 at the lower end of thescreen frame. While the squeegee is traveling up and down. it is held against the screen with a yielding pressure supplied by the compression spring I". Means for swinging the arm IIB downward and thereby withdrawing the squeegee from the screen, includes a rock arm I24 attached by a pivot pin I25-to the slide block I06. The arm I24 has a slot and pin connection I21 with the squeegee arm II6. As the slide block I 06 carries the squeegee downward and approaches the limit of its downward movement, the arm I24 strikes a stop bolt I28 adjustably mounted in the plate 95, so that the arm I24 is swung upwardly and swings the squeegee away from the screen. During the up-stroke of the squeegee, as it nears the limit of its movement, a lug I29 on the arm I 24 the squeegee away from the screen. The stop I 3| is carried on a block I32 adjustably slidable up and down in the frame 94 and clamped in adjusted position by a bolt I33. 7
Means for'locking the squeegee arm in a retracted position out of contact with the screen, comprises a latch I34 pivoted on the arm III. When it is desired to lockthe squeegee in its retracted position, the operator swings the arm 6 downwardly and rearwardly about the pivot II3, thereby raising the yoke I2I a sufllcient distance to permit the latch'I34 to engage beneath the yoke, thereby locking the squeegee in its retracted as presently described. The
'- position. A spring pressed detent I35 moves the latch to locking position.
Safety devices, individual to the decorating units are provided for preventing operation. of a screen cylinder C2 when there is no bottle or workpiece in the chucks and thereby preventing the screen from being moved forward. One such safety device is illustrated in Figs. 11 and 12. It includes a screen safety valve V which is operated by a rock arm I36 mounted to swing on a pivot I31 and having its free end in position to bear against the valve stem. The arm is normally held retracted by a coil spring I38, leaving the valve open for normal operation. When a bottle is missing, the chuck holder 62 carrying the neck chuck is moved downward below normal position, thereby operating mechanism by which the valve V is held closed. Such mechanism (Fig. 12) includes a rod I39 mounted for vertical movement in the hub IF. A coil spring I under compression bears upwardly against a collar I42 on the rod, with the latter projecting into the path of the neck chuck holder 62. The rod is pivoted at its lower end to a rock arm I43 fulcrumed on a pin I44. The rock arm is connected through a link I45 to a slide bar I46 mounted to slide radially of the carriage. When the carriage is brought to rest, the slide I46 is in position to engage a roll I41 on the arm I36 and move, it inward into position to close the valve V". This valve controls the screen motor C and, when closed, prevents its operation, as hereinafter described. The roll I41 runs on the periphery of the carriage II while the latter is rotating.
The control valve V which controls the operation of the screen motor C and the valve actuating mechanism are.illustrated in Figs. 8, 9 and 10. The valve V comprises a valve block I58 formed with lower and upper valve chambers II and I52 respectively, communicating with pipes 288 and 2". Upper and lower valve stems I55 and I56 are slidably mounted in screw-threaded plugs I51 in the slide block. Each valve stem carries a valve disk I58 (Fig. which seats on a ring gasket I 59, the disk being normally held in sealing contact with the gasket by a coil spring IBI. The tubular valve stem I 55 includes an inner slidable member I62 with a head I53.
The valve stems are moved inwardly alternatively against the compressive force of the springs I6I by a rocker I64 mounted to-swing about a pivot pin I65 carried in lugs I66 on the valve block. Latches I61 and I68 are connected by pivots I69 to the upper and lower ends of the rocker I64. The latches are formed with hooks to engage keepers I1I on the valve block and are also formed with arms I for releasing the latches. The latches are held in looking position by spring pressed detents I12.
A latch releasing switch I13 is fulcrumed to swing on the pivot pin I65 and is formed with 8 tends horizontally in line with the pivot pin I 65 (Fig. 13).
The operation of the switching mechanism is as follows:
Commencing with the parts in the positions shown in Fig. 9, the motor '22 operates to retract the screen and withdraw the finger I88 from contact with the switch I13, so that the arm I16 is swung to vertical position by the coil spring I18, thereby swinging the finger I88 to a horizontal position (Fig. 13). When the screen frame is again moved forward to operative position by its motor C' the finger I88 rides the upper inclined surface of the V-shaped cam or nose I85 formed on the switch I13, thereby rocking the switch counter-clockwise. During the initial rocking movement of the switch, the lower finger I14 swings the lower latch arm I15 and releases the lower latch I68. As the latch is thus released, the end of the finger I88 engages a surface I88 of the rocker I64, so that the continued movement of said finger with the screen carrier swings the rocker I54 about its fulcrum and causes theupper latch to engage its keeper III. This swinging movement of the rocker moves the upper valve stem I inward and at the same time releases the lower valve stem I58, permitting the spring I6I to move the valve to closed position. The switch I13 is held in either position to which it is thrown, by the spring pressed ball I88 engaging notches I89 in the switch.
Operation Referring to Fig. 13,-air under pressure is supplied through a main pipe line 288, for operating the machine. Assuming the parts to be in the positions shown in Fig, 13 and a decorated bottle held in the chucks at station I, a cycle of operations is initiated by the operator depressing a foot pedal 2M. This opens a pilot valve V and supplies air from the main air pipe 288 through pipes 282, .282, valve V pipe 283, valve V and pipe 284 to the motor C (Fig. 3), thereby raising the motor piston and causing it to raise the neck chuck 28, thus releasing the decorated bottle B. The operator then removes the bottle and places a bare bottle in position between the chucks, and then releases the pressure on the foot pedal 28I. This closes the valve V and cuts off the air supply to the chuck lifting motor C so that the piston is lowered by the spring 16, thereby releasing the neck chuck 28 so that it is lowered by the spring H and holds the bottle. As the piston moves down, the pawl 83 attached to the piston rod forces the rock arm 8I downward, causing it to open the valve V This supplies air pressure from the main 288 through pipe 282, valve V pipe 285, through the open pilot valve V and fingers I14 to engage the latch arms I15. The
switch I13 is free to rock about its pivot independently of the rocker I64. Means for actuating the rocker I64 includes a rock arm I16 pivotally mounted to rock on a pivot pin I 18 on a bracket I11 connected to the screen carrier for horizontal movement therewith. The arm I16 is normally held in a vertical depending position by means of a coil spring I19 mounted on a stem I8I slidable lengthwise within the hollow arm I16 and having a head I82. The pin I18 has a fiat surface I83 against which the head I82 is held by the spring. The arm I16 is formed with a finger I88, which, when the screen carrier is retracted, ex-
pipe 288 to the valve V It will be noted that the valve V (Fig. 5) has been opened by the upward movement of the driving pin 33. The air pressure supplied to the valve V as just described, shifts the valve and supplies air pressure beneath the piston of the motor C (Fig. 3) and thereby actuates the motor and causes it to raise the locking pin 38 out of engagement with the carriage I1. This upward movement of the motor piston'also causes the contact rod 48 connected to the piston rod to open the valve V. This supplies air pressure from the pipe 285 through a pipe 281, valve V pipe 289, to the control valve V of the carriage driving motor C. The valve is thus shifted .to supply air behind the motor piston 21 (Fig. 2), causing it to index the carriage, thereby carrying the bottle 13 from station I to decorating position at station 2. The
thereby lowering the locking pin 38 and locking the carriage in its indexed po ition, and withdrawing the driving pin 33. The shifting of the valve V also cuts off the air supply through the pipe 203 to the valve V". The operation of the motor (I also lowers the contact rod 49, thereby opening the valve V. This supplies air from the main 200, through pipe 212, valve V and pipe M3 to the driving motor valve V so that the latter is reversed, causing the driving motor C to start its return stroke for returning the carriage indexing arm 32. The opening of the valve V, as above noted, as the motor C is completing the carriage driving stroke, also admits air pressure through the pipe 2L0, 2 to the trip motor C causing it to operate the pawl 83, thus releasing the trip lever 8| and permitting the self-closing valve V to close. The opening of the valve V also admits air through a pipe 2 to the left-hand end of the valve V thereby shifting the latter into position to admit'air through pipes 2I5, the valves V and pipes 2 l6 to the screen motors C of the four decorating units. While the indexing motor piston is making its return stroke, the decorating units any one of the holding units, the neck chuck holder 62 01'- are operated. If a bottle is missing from such unit moves downward below normal position and operates through the mechanism shown in Figs. 11 and 12 to close the corresponding safety valve V", so that the decorating unit at said station remains inoperative. At the stations where bottles are in position, the valves V are open (for normal operation), and air is supplied through the pipes 2 I 5, valves V", and pipes M6 for operating the screen motors 0*, thereby moving the screens to decorating position. During this movement at each station, the finger I80 operates the rocker I64 (Fig. 9), thereby depressing one or the other of the valve stems I55, I56 for opening one or the othertof the valve disks of the valve V This supplies air through either an upper pipe ill or lower pipe -2I8 to the upper or lower end of the cylinder of the motor C thus operating the motor to impart either an up-stroke or a down-stroke to the squeegee 26, thereby decorating the bottle. This completes the cycle. l
