- Renewed October 29, 1936 zr claims.

This invention is directed to new and useful improvements in banding machines of the type used for applying colored paint orhenamel bands to glassware, particularly drinking tumblers, for decorative purposes.

The machine comprises a turreton which are mounted a plurality of chucks for holding the articles to be banded, a plurality of paint reservoirs and series of paint applying discs positioned around the .turret andv means for moving the chucks from one series o! discs to the next series for applying diiierent colored bands to the articles on the chucks in predetermined de- -alan.

The primary object of this invention is to provide such a machine that may be eiliciently operated by a minimum of operators to produce completely iinished banded glassware at high speed.

Another object to a great extent automatic in operation and will decorate glassware accurately with a plurality of diiierent colored bands arranged in .predetermined relationship.

A further object is`to provide such a machine adapted to handle a plurality of glassware units4 at once and arranged compactly so as to take up the minimum of floor space.

'Still another objectis to provide a banding machine that will automaticallyvhold the glass units on the chucks while they are being treated and will automatically release them from the chuck when they are finished. I

Stili a further object is to provide a.l banding machine in which the articles on the chucks are rotated by the paint applying discs when paint is being applied and by independent means at greater speed at other times whereby the paint is evenly distributed and running of the paint is averted. l

By'way oi further explanation it is to be noted that when the tumbler leaves the paint applying discs it tends to bring with it from each disc va surplus of paint or enamel. This is known as the tail of the paintl and the increased speed of rotation of the tumbler when it leaves the discs whips the tail of the paint into proper alignment with the applied band and Adistributes it evenly as stated. i

AAnother object of this invention is to provide such a bandingmachine in which the painted articles are thoroughly dried before being automatically released from the chucks.

Still a further object is to provide means .for

retaining the decorated units loosely on thechucks after being released from operablerelation with the chucks and until removed to the lehr.

Another object is to provide such a machine with positive means for accurately positioning 5 the chuck at the paint applying stations.

Still other objects and advantages will become apparent from an examination of the following detailed description.

In the drawings: e Fig. 1 is a side elevation partly in section oi' a banding machine embodying the improvements and inventions herein set forth.

Fig. 2 is a central vertical section view of a portion of the upper half of the machine shown in'15 Fig. 1.

Fig. 6 is an enlarged section `taken on line 8 8 of Fig. 2, showing the positioning mechanism.

The main elements of the banding machine are 25 a baseKA which supports the mechanism, a motor B for causing continuous movement of certain parts, a centrally `and vertically positioned hol-i lowl rotatable shaft C operably geared to the motor B, two paint applying stations D compris- 30 ing paint reservoirs' and paint applying discs, a

turret E carrying four chucks, a -drier F and a take-cif guard rail G. v

In detail the shaft i of the-motor B is keyed to a horizontally extending worm ,gear 2 appro- 35 priately mounted for `rotation in anti-friction bearings 3 and 4 as clearly shown in Fig. 4. Worm gear 2 is meshed with `a circular gear S that is also mounted in 'anti-'friction bearings and is keyed to the hollow rotatable shaft C. A 40 housing 6 encloses these gears.

Just above this housing a vacuumsupplypipe l leads to the shaft C which isuprovided with openings 8 at this point leading to its interior. 45 Part of housing 6 extends `upwardly past these openings and around the shaft' and is provided with a chamber 9 communicatingv with theopenings 8. A threaded opening 9a' is provided into which the supply pipe 'I is threaded. thus provid-v 5u'` Higher on shaft C is keyed a. bevel gear .II

that is meshed with another bevel gear I2 that is in turn keyed to a horizontal shaft I3 which extends through the housing I4 of the lower portion of the machine and which has mounted on its outer end a pulley wheel I5.

The shaft C is reduced in diameter at its upper end. A portion of the shaft at this point is provided with threads I6. A circular friction plate I1, with a split hub I8 having threads I9 to cooperate with the threads I6, is adjustably mounted on the shaft by means of the threads and a screw 20 positioned through the split part of the hub which is unloosened to permit vertical adjustment and is tightened to clamp the hub to the shaft.

Above the friction plate I1 at its upper end the shaft has two openings 2| communicating with its interior. A sleeve 22 is non-rotatably mounted around the shaft. has a chamber 22a communicating with openings 2I, is provided with sealing members 23 and 23aand is supported by arm 24. Four outlets 25 lead from the sleeve and into these are threaded four supply pipes 26. A plug 21 closes the upper end of the shaft.

The top surface 28 of the housing I4 is a cam plate provided with an annular adjustable cam 29 and a stop plate 30 having a stop member 30a with stop grooves 30D at predetermined positions for the purposes hereinafter stated. A set screw 29a holds the cam 29 in the .position desired. A bushing 3| surrounds the shaft C,

is positioned between the cam plate and the shaft, is provided with a shoulderl 32 immediately above the cam plate and extends upwardly therefrom.

The turret E is rotatably mounted around said bushing 3| above the shoulder 32 and on the anti-friction bearings 33. The turret comprises four forked arms 34 which extend upwardly and outwardly and in each of which is pivotally mounted a chuck mechanism 35 comprising a housing 36, a hollow rotatable shaft 31, a drive wheel 38 on the inner end of the shaft and a chuck assembly 39 on the outer end. The mechanism is pivotably and adjustably mounted between the arms of the forked member 34 by means of a U-shaped bracket 40 secured to the under part of housing 36 that is provided with three conical holes 4I at each side. Conically pointed bolts 42' extend through the arms of member 34 and bear in the holes 4| dependent upon the height adjustment desired. Mounted on the top of housing 36 is an arm 43 provided with a knob 44. The chuck assembly 39 cornprises a tapered wooden head 45 provided with longitudinally extending ribs 45a, mounted on the end of shaft 31 and movable longitudinally thereon, a head 46 on the end of the shaft and a helical spring 41 positioned around the shaft to force cylinder 45 against head 46. A stop and sealing member 48 is provided with an annular groove 48a to contact the rim of the article to be banded. A port 49 opens to the inside of shaft 31 and is positioned so as to be closed by cylinder 45 when in normal position. Adjacent the drive wheel 38 at the other end of shaft 31 are ports 50 surrounded by an extension 5I of housing 36 which is provided with a chamber 52 communicating with the ports. The end of the extension 5I is closed by a gland 53 which seals the connection with the rotatable shaft. A

pipe 54 is threaded in the extension 5I and communicates with chamber 52. An apertured lug 55 is secured to the underside of extension 5I at the inner end. One end of coiled spring 56 is secured to lug 55 and the other to an anchorage 51 on the lower portion of the turret E so as to normally hold drive wheel 38 in contact with the upper surface of friction plate I1. 'A glass tumbler-58 is shown on the chuck.

For each such chuck assembly there is a valve 59 mounted on the lower portion of the turret and comprising an inlet port 68, and outlet port 6I, and an exhaust port 62. A valve seat 63 and plate 64 are provided for opening and closing the connection between the inlet and outlet ports and a valve seat 65 and plate 66 are provided for opening and closing the exhaust port 62. 'Ihese plates are loosely mounted on valve stem 61 between nut 68 and shoulder 69 on the outer end of the stem. A coil spring 18 positioned around the stern between the plates forces them away from each other. Above nut 68 another coil spring 1I is positioned around the stem and normally keeps the plate 66 on its seat 65 to close the exhaust port and the plate 64 in open position to connect the inlet and outlet ports. stem 61 and extending from the valve housing 12 is a cam follower 13. When follower 13 is forced upwardly by engagement with cam 29 valve plate 66 is unseated and valve plate 64 is seated to close the connection between the inlet and outlet ports and open the exhaust port to the atmosphere. Threaded in the housing 12 and communicating with the inlet port is a pipe 14 and similarly a pipe 15 communicates with the outlet port. Pipe 14 communicates through proper pipe and hose connections with its supply pipe 26 and pipe 15 with pipe 54 that leads to the inside of hollow shaft 31 on the chuck mechanism.

Depending from the turret below ea'ch forked member 34 is a housing 16 within which is a downwardly extending vertically m'ovable follower 11 provided with a reduced portion 18 around which is positioned a coil spring 19 and a threaded head 89 which receives a nut 8| above a shoulder 82 in the housing. 'I'he lower end of the follower 11 is undercut as at 83 and bevelled as at 84. A threaded hole 85 is provided in the side of the housing, a vertical groove 86 is in the side of the follower and a bolt 81 threaded through hole 85 and projecting into groove 86 prevents the follower from turning out of position. The spring 19 holds the follower in extended position.

Each paint applying station is mounted on an outwardly extending bracket 88 and comprises a rotatable shaft 89 extending radially from the machine mounted on supports 90 and having mounted on its inner end a pulley wheel 9| above the pulley wheel I5. 'Ihese are operably joined by a belt 92. Removably mounted on shaft 89 between the supports 90 are a plurality of vertically resilient steel paint applying discs 93 adapted to rotate'with the shaft. The discs are vertically resilient by means of floating hubs yieldably held in position with springs and may be arranged in various positions relative to each other and to the discs at the other station.

Below the paint applying discs at each station is a paint reservoir 94 into which the discs extend. Oscillatable fins 95 are positioned in the reservoirs to agitate the paint or enamel. Arms 96 secured to the fins are all joined together by Secured to the lower end of the otally joined to the lower end of lever ll, the outer end of which is slidably mounted through bracket 99.

A cylinder "Il is mounted on shaft l! near its inner end' and is provided on its outer surface with an eccentric groove III.

otallyg mounted at its center to a bracket I l2 and the inner side of its upper end has a stud Ill that extends into and follows groove Ml when shaft 89 is rotated.

Positioned beneath the path of the chucks for an arc4 of 160 after leaving the second paint applying station is a hot air manifold IMwhich directs heated dry air upon the rotating freshly banded tumblers. The air is forced through the manifold by a blower I! and the air is warmed by a heater |05a of any desired type positioned between the blower and the manifold.

From a point adjacent the end of the drier manifold |04 is mounted a vertical arcuate takeoi guardrail |06 positioned in the same horizontal plane as the chucks and outward from the ends of the chucks a short distance and extending for about 60 adjacent the path of the chucks.

y yThis rail is mounted on bracket |01 and is horizontally adjustable by means of bolts IIIIa and slot lill-b depending upon the height of the glasswarey banded.

The supply pipe 1 communicates with the vacuum pump |08 of any desired type to present suction to certain parts of the machine.

-In operation the motor B through the gearing hereinabove described causes the friction plate I 'l and the disc bearing shaft Il to continuously rotate. In normal position the friction plate contacts drive wheels 38, causing the chucks to also rotate. It is clear that the paint applying discs pick up paint from th reservoirs and that the fins keep the paint stirred. Paint of one color is within one reservoir and of another color in the other one.

Vacuum is present up to the port 49 on the chuck for the reason that the valve 59 is in normal or open position and closed to the atmosphere.

The operator takes a glass tumbler to be banded and pushes it on a chuck until its rim contacts the stop member 43. This moves the wooden head 45 inwardly against the spring 41 and thereby opens port Il in the outer end of shaft,A 31. Air is thus exhausted from the tumbler so as to hold the tmbler in applied position. The operator then grasps the knob ll of arm 43 and swings the chuck in a counterclockwise direction to a point just past the first paint ap plying station and then swings it back, in a clockwise direction, until the end of follower 'l1 abuts the stop shoulder lllb which positions the tumbler exactly above the rst series of paint applying discs. The operator then moves the chuck downward until the tumbler contacts the edges of the paint applying discs 93. In this movement it is to be noted that drive wheel 38 is moved out of contact with the friction plate I1 and the chuck ceases to rotate. The contact between the paint applying discs and the side of the glass tumbler rotates the chuck while theI paint is applied. When the rst series of bands have been applied the operator lifts the tumbler from the discs, moves the chuck assembly to a point just past the next station and repeats the operation. Between paint applying operations the chuck is constantly rotating at a speed greater than when rotated by the paint applying discs' t arouse means of a bar 91, the inner end of which is piv- Lever 9| is pivtoevenly distribute the paint and prevent it from running and to whip the tail of the paint into alignment. After both series of bands have been applied the operator swings the next chuck into operating position, applies a new tumbler and repeats the above described steps. Thus the first mentioned tumbler is gradually moved about the machine andl is constantly rotating. 'Ihe drier manifold |04 directs heated air upwards against the rotating tumbler for about 160 of its travel after leaving the second paint applying station. When the tumbler reaches a position at the end of the drierand at the start of rail |06, the valve follower 13 is moved upwardly by cam 29, thus cutting od the vacuum supply to the chuck and opening the exhaust port 62 to admit airunder atmospheric pressure tothe tumbler. The spring 41 on the chuck then forces the head 45 back against the stop I6 and releases the banded tumbler which is protected from falling from the chuck by the rail I 06. The tumbler rides thusly until removed by anoperator.

It is obvious that more paint applying stations may be added if desired and that the reservoirs shown may be divided to hold different colored paints.
