'I'his invention relates to new and useful improvementsin a machine adapted to paint various colored and spaced bands on drinking tum` blers or similar articles. As a new decorative idea it is now popular to ornament drinking glasses with a series of spaced painted bands extending around the periphery of the glass. These bands may be equally or unequally spaced and may be of similar or contrasting colors, according to taste.' To perform this work by hand is tedious and difficult and necessitates a much higher price being charged for the finished article.

The primary object of the invention herein described is to provide a machine which will neatly and eiectively perform this function and which is practically automatic, so that a person vwith no particular skill can operate it and so decorate many tumblers in a minimum of time.

Another object is to provide an adjustable mechanism whereby painted bands may be placed around the periphery of a tumbler in predetermined spaced relationship.

Still another object is to provide such a machine whereby such bands may be so placed in predetermined color combinations.

A further object is to provide novel means for agitating the paint contained in the reservoirs so as to maintain a constant smooth mixture'.

Another object is to provide novel yieldable paint applying discs whereby any slight differences in the surfaces of the tumbler or the discsis compensated for.

Still a further object is to provide acushioned chuck for holding tumblers to be so decorated and a stop member adjacent said chuck whereby the relative position of the tumblers and the paint applying discs is constant.

Another object is to provide means for manually rotating the tumbler after the paint has bee'n applied so as to smooth out any gobs of paintl which may collect on the decorated area. Another object is to provide a lock meansfor holding the tumbler o n the chuck.

Further objects and advantages will be apparent from the. drawings and the description.

The banding machine comprises generally a chuck assembly A for receiving and rotating the tumblers to be decorated, a carriage member B on one end of which is mounted the chuck assembly A'and which is pivotable vertically and movable horizontally, a plurality of paint reservoirs C adapted to contain paint, enamel or other coloring matter, paint agitators D and a series of paint applying discs E, rotatably mounted ona shaft assembly F between the chuck assembly A and the paint reservoirs C.

In detail the chuck assembly A comprises a shaft l rotatably mounted by means of ball bearing assembly 2 within the rectangular block 3 which is adjustably secured by means of stud and nut 3c to arm 4 extending from one end of the carriage member B and which also carries handle 5. On 'one end of shaft 1 adjacent block 3 is a knurled wheel 6 for manually rotating the shaft and adjacent the other side of block 3 on shaft l. i's mounted a drive wheel 7. Adjacent wheel 7 is mounted a stop disc 8 adapted to contact with the rim of the tumbler 9 to limit longitudinal movement and a centering disc 8a adapted to contact the inner edge of the rim to insure true rotation of the tumbler. The chuck proper comprises a tapered cylinder 10 mounted onthe shaft 1, its larger end towards stop member 8, and movable longitudinally with relation thereto. A helical spring l1 is positioned about the shaft 1 and fits within a seat 12 formed within chuck 10 and isadapted to force chuck 10 away from stop member 8. A bolt 13 is secured within theother end vof shaft 1, thel enlarged circular head 14 thereof forming a stop adapted to prevent chuck 10 from being forced off the shaft 1 by spring 11.

A locking mechanismfor holding the tumbler 9 on chuck 10 is provided and comprises a supporting ring arm 15 secured to the carriage member B and extending to a point adjacent the smaller endof chuck 10. Mounted on said arm so as to be vertically pivotable is a bracket 16 and on said bracket is mounted a locking lever 17 adapted to be slightly pivoted in a horizontal plane. Lever 17 carries a handle 18 and a spherically headed bearing member 19 adapted to contact the center of Bassum) the bottom outside surface of the tumbler 9. A coiled spring 20 positioned between the other end of said lever 17 and bracket 16 causes the bearing member 19 to press against the tumbler. An adjustable screw and lock nut assembly 21 provides a stop means for limiting the downward pivotal movement of bracket 16. Thus by means of handle 18 the lever 17 may be moved horizontally a slight distance so as to bring bearing member 19 out of contact with the bottom of tumbler 9 and then swing upwardly together with the bracket 16 so that tumbler 9 may be removed and another one placed on chuck 10.

The carriage member B comprises a rectangular frame 22 on one end of which are mounted the chuck assembly and locking mechanism as hereinabove described, and on the other end of which is slidably mounted a counterweight 23 and spacers 23a. Clamp screws 23h lock counterweight 23 in proper position. A cylindrical track or rod 24 is mounted at right angles to frame 22 and parallel to chuck assembly A by means of vertical brackets 25 bolted on the base 26 of the machine. Frame 22 is mounted on track 24 so as to be vertically pivotable and horizontally movable from one of its two alternative operative positions to the other by means of three flanged wheels 27 secured to frame 22 between its ends. The wheels are in the same vertical plane but two of them ride on the top surface of rod 24 and the other is positioned below said rod and between the other two. Two similar bifurcated support members 28 are vertically mounted on base 26, one adjacent the chuck assembly carrying end of carriage member B in each of its operative positions and adapted to receive arm 4 of frame 22 to prevent horizontal movement of frame 22 when in operating position. Stop members 29 are positioned at each end of track 24 to limit the length of track over which frame 22 can be horizontally moved so that one of the support members 28 and arm 4 are aligned at each terminal point. Thus it is clear that by grasping handle the entire chuck assembly may be lifted upwards (the frame 22 pivoting about rod 24) and then moved horizontally between the two stop members 29 on the track 214. The bifurcated supports 28 provide two positions in which the chuck assembly can be held against horizontal movement.

A is positioned shaft assembly F comprising the main shaft 35 journaled in the adjustable bearing assemblies 36 which provide vertical adjustments by means of'set screw 37 and horizontal adjustment by means of screws and nuts 38.

' The diameter of shaft 35 is greater between bearings 36, the ends of said enlarged part being threaded as at 39 and washers 40, positioned between the ends of said enlarged parts and the bearings 36 serve as thrust bearings. 35 extends beyond one of said bearings 36 and is rotated by any desired source of power. Approximately midway between the bearings 36 and The shaft directly above lever 34 there is mounted on shaft 35 a cylinder 41 having a continuous cam groove 41a in its outer surface. A pin 42 extendsv upwardly from one end of lever 34 and into the cam groove of cylinder 41. When shaft 35 rotates the diagonal cam groove changes position causing lever 34 to oscillate. Sleeves 43 are mounted on said shaft 35 at each side of cylinder 41 and are secured so as to rotate with the shaft by means of nuts 44 screwed on the threaded portions 39 of the shaft. Also mounted on shaft 35 and adjacent the ends of reservoirs 30 are grooved soft rubber wheels 45 which are engaged by the drive wheel 7 on the chuck and are yieldable vertically to allow a tumbler on chuck to be moved into full contact with discs E. The paint applying discs E are mounted on the sleeves 43 of the shaft 35, are spaced as desired by spacing members 46 and are secured in such position by nuts 47 tightened on the threaded ends 48 of sleeves 43.

Paint applying discs E each comprises a steel ring 49, the outer peripheral surface of the ring having a width corresponding approximately to the width of the band to be painted on the tumbler. The ring 49 is held frictionally between a pair of discs 50 screwed to a hub 51, the hub and discs being clamped on sleeve 43 between a pair of the spacing sleeves 46. Positioned between the hub 5l and the ring 49 is a curved band spring 52. By this construction the paint applying discs E are yieldable and accordingly align themselves to the surface of the periphery of the tumbler to be banded and automatically compensate for any irregularities in the surface of the tumbler and for any unequal wear in the edges of the discs.

In operation; The reservoirs are llcd with paint or enamel of the colors desired. The paint applying discs are arranged on the main shaft in number and position according to design to be placed on tumbler. The chuck assembly is swung up out of contact with the discs and a tumbler is placed on chuck 10 which has been angularly adjusted by stud` and nut 3a in accordance with the taper of the tumbler and the tumbler and chuck moved in against spring l1 until the rim of the tumbler contactsgstop member 8 and the inner edge of the rim contacts the centering disc 8a.' Then the locking mechanism is pivoted downwardly until bearing member 19 is substantially opposite the center of the bottom of the glass, the screw and nut means 22 being adjusted to stop the locking mechanism when swung down to this position. Locking lever 17 is then allowed to swing horizontally by spring 1'6, thus causing bearing member 19 to contact the base of the tumbler. The chuck assembly is then pivoted downwardly, arm 4 fitting within bifurcated member 28, drive wheel 7 within one of the yieldable grooved wheels 45 which yieldably limits downward movement and also rotates chuck and the constantly rotating paint applying discs contacting the periphery of the tumbler. Due to the friction between drive wheel 7 and grooved wheel 45, chuck 10 and tumbler 9 are caused to rotate. The discs moving through the paint reservoirs pick up paint and transfer it to the side of the tumbler as they rotate against it. As soon as the banding has been thus completed from one reser- :voir the chuck is swung upwardly by means of handle 5, taking the tumbler out of contact with the discs and the knurled wheel 6 is manually rotated to spin the tumbler and smooth out any gobs of paint left by-the discs. This first operation has produced the bands of any desired color as indicated by X in Fig. 9. The chuck assembly is then manually moved horizontally'by means of carriage member B until the tumbler is above the second reservoir at which point it is swung down, arm 4 fitting within the next member 28 and drive wheel 'I on the next grooved wheel 45, the second series of discs contacting the periphery of the tumbler between the bands heretofore made or according to their spacing. The second reservoir being lled with different colored paint, different colored bands result when the discs are rotated against the tumbler. Thus a second series of bands is applied to the tumbler of a color different than that of the rst series such as illustrated by Y, Fig. 9.

It is obvious that many different designs can be so produced, the number of colors being determined by the number of paint reservoirs, the number of bands by the number of discsand the design by the spacing and relative position of the various series of discs. Should additional colors be desired without adding to the number of reservoirs it is entirely practical to supply partitions for the reservoirs (as indicated at 53 in the right hand reservoir shown in Fig. 2), dividing them into sections, each section adapted to receive a differently colored paint.

The cushioned chuck 10 and stop member 8 enables the bands to be applied uniformly to all tumblers of the same size, for when the rims of tumblers applied to the chuck 10 contact stop 8 and are held in that position by the locking mechanism the relative position of the tumbler and the paint applying discs is always the same.
