(01.101-40) This invention relates to a machine for printing directly upon the surface of glassware, synthetic moulded compositions, metal, or any other hard impenetrable surface. The articles formed of such materials may be bottles, jars, tumblers, bulbs, cans, and the like, and are supplied with a design, trade mark, or other insignia which will be permanent, or substantially so. The usefulness of the articles will thus be materially increased, and the insignia thereon may be printed lin one or more colors.

An object of our invention is to provide a machine of the character stated, in which insignias are placed upon articles formed of a hard iml 5 penetrable material, without having to print labels on paper or other sheet material, and then having to ax the labels to the articles.

Another object is to provide a novel machine for printing on hard surfaced articles, said machine receiving, holding and printing one or more of these articles; said receiving, holding and printing being done automatically, accurately and with great rapidity.

A feature of our machine is a revolving carrier 5 in which the articles are received, a movable printing frame in which the dies. cuts or stencils are held, the articles being moved into engagement with the p ting frame and subsequently printed.

Another object is to provide a novel means of receiving and holding the articles tobe printed, revolving said articles if they are round, said revolving of the articles being synchronous with the movement of the printing frame. Thus, the printing is accomplished during the movement of the printing frame and the revolving of the articles.

A further feature of our invention is to provide a novel means of discharging the articles after they have been printed, upon a. conveyor whereby the articles are moved away from printing position. y y

'Still another object is to provide a novel Vconveyor for the articles, which conveyor moves intermittently and carries the articles in proper position to be printed upon.

Another object of our invention is to provide a multi-color printing mechanism which will be interchangeable with the stencil and squeegee device, said mechanism being constructed as a unit attachment and operated from the motive power of the machine.

This invention is a continuation in part of our copending application, Ser. No. 28,886, for Printing machine for impenetrable surfaces.

Our continuous printing machine comprises a pair of side frame members I. The frame is preferably built up of structural members, such as structural shapes, plates, and the like. A substantially horizontal conveyor belt 2 extends over horizontal rollers 3, 4, and the articles to be printed are rolled onto the conveyor belt and then moved into the machine to be caught by an elevator or rotary conveyor, as will be subsequently described.

A horizontal shaft 5 is journaled in the frame members I, and this shaft carries a pair of discs 6, 1 secured thereto, said discs being positioned adjacent the frame members l. Each of the discs 6, 'l is provided with means to engage and hold the articles to be printed, and in the present instance, this article will be considered to be a bottle.

Each of the discs carries a plurality of chucks 8 which are positioned inwardly of the discs 6, 1. The construction of all of the chucks is identical. A chuck on each of the discs 6, IA is yieldably pressed inwardly against the ends of the bottle, thus holding the bottle in a horizontal position and conveying said bottle upwardly as the discs rotate, as will be further described. Each of the discs is provided with a trunnion 9 xedly attached thereto and journaled in the disc. A coil spring l0 encircles the trunnion and is positioned between the disc and the chuck, thus yieldably pressing the chuck inwardly against the end of the bottle. Each of the trlinnions is formed with a head Il on the outer end thereof and the head engages a box cam I2 as the discs rotate, thereby drawing the trunnions and the chucks outwardly to release the bottle., The bottle moves inwardly on the conveyor and since the box cam I2 terminates at the lower end of the discs so that the trunnion 9 is released when the chucks are in the lowermost position, the. bottle is engaged by the.` chucks 'and carried upwardly as the discs rotate.

The cam I2 starts adjacent the uppermost position of the bottle so that continued movement of the discs will retract the chucks and permit the bottle to drop I3. leys on the shaft 1 and around a pulley I4 journaled adjacent the intake end of our machine.

The shaft 5 and the discs 6 and 1 are intermittently` rotated thru a Geneva gear I5 on the shaft 5. This Geneva gear comprisesa timing wheel I6 having an inner disc I1 constructed integrally with the hub I8, and the outer disc I 9 secured thereto by bolts 20. Between the two discs is a third or driving gear 2| which is rotatably mounted on the hub I8. This central gear 2| constitutes an idler for the chain 22. 'I'he method of driving this chain will be subsequently described.

Spaced equidistantly on the chain in predetermined positions is a number of lugs 23 which are designed to engage and swing a pawl 24 pivotally mounted on the frame I. This pawl 24 is provided with a projection 25 which engages a notch 2G in the flange of the disc I1. A nurnber of these notches are provided and they are spaced equidistantly around the ange to correspond with the number and position of the chucks 8.

From the foregoing it will be seen that as the chain 22 rotates, the pawl 24 will be lifted by the lug 23, thus releasing the discs I1 and I9 and permitting them to rotate with the gear 2| because of the frictional engagement of the discs and gear. 'Ihe pawl is provided with a roller 21 which is mounted on a pin projecting from the pawl. This roller is engaged by the lug 23 when actuating the pawl. When the lug disengages the roller, the pawl is again brought into contact with the flange of the disc I1 by means of a spring 28 and therefore engages the next notch as the wheel rotates thereby holding the same non-rotatable until again actuated by the sequence of operation.

The chain 22 is driven from a motor 29 which drives thru a reduction gear 30 thence to a shaft 3|. The chain encircles a sprocket 32 on the shaft 3| and also an idler sprocket 33. which is journaled to the frame below the Geneva gear I5.

A rectangular table 34 is reciprocally mounted between the frame members I. This table ts in longitudinal grooves or tracks 35 in the frame.

upon the discharge conveyor The table 34 is continuously reciprocated by the following arrangement: A shaft 36 is journaled in the frame members I and a sprocket 31 is attached to one end thereof. The sprocket and shaft are driven by a chain 38 which chain encircles a sprocket on the shaft 3|. The shaft 36 is formed with a crank arm 39 to which a pitman 40 is journaled. The other end of the pitman is pivotally attached to the table 34. Thus, as the crank arm 39 rotates, the table 34 is reciprocated.

A printing frame the table .34 by means of a plurality of clips 42.

The discharge conveyor extends around pul-v 4| is adjustably mounted onl The printing f rame is adjustable both longitudinally and transversely of the machine so thatthe printing can be properly positioned on thebottle. The bottom of the frame 4| is made of cloth, ne mesh wire, or the like, andthe stencil or pattern is attached to the bottom of the printing frame, all'of which is usual and well known in the art.

A squeegee is adjustably mounted above the printing frame 4| in a manner described in our copending application. y

In order that the chucks 8 will rotate at the same rate/as the reciprocation of the table 34, We attach or.` form a gear 43 on the periphery of each of the chucks and a co-acting gear rack 44 is formed on the under side of the printing frame 34. Thus, there is a positive transmission of the movement of the printing frame to the chucks as the gears on the chuck engage the rack on the frame. As the upper bottle is being released from its engaging chucks, the bottom set of chucks is vgripping another bottle. Thus a bottle is continuously engaged and carried upwardly to a printing position, is rotated while in printing position, the printing table moving over the bottle, imprinting an insignia thereon, the bottle being then released and discharged, all in continuous sequence.

'I'he multi-color printing attachment shown in Figs. 5 and 6 comprises a printing unit mounted between two side members 45 which is designed to bebolted to the upper part of the frame I. A drum 46 is rotatably mounted on a shaft 41 upon which a sprocket 48 is attached. The drum is rotated by means of the chain 49 which in turn is trained over an idler sprocket l5I! and to the reduction gear 30 of the motor 29. A plurality of printing blocks 5I are secured on the drum by metal bands 52 in predetermined positions thereon. A different color design is embossed on each of the blocks. A rubber flange 53 is provided on each end of the drum 46 and these anges engage the chucks 8 to rotate the same during the printing operation.

It will be seen that the blocks 5| are designed to engage the object to be printed, as shown in Fig. 6.

The colored inks are carried in reservoirs 54 in which a roller 55 rotates. 'Ihis last named roller engages other rollers 56 upon which the ink is evenly distributed and conveyed to the printing blocks 5|. 'The reservoir and rollers are reciprocally mounted on a track 51 and normally urged toward the drum by springs 58. 'Ihe innermost roller is provided with a pair of rollers 59 mounted on axles 60, said rollers engaging the cam faces 6| mounted on the shaft 41. These cam surfaces are arranged in relation to the respective color printing blocks 5I in such a manner that each set of rollers 55 carrying a certain vcolor will be permitted to engage the particular block of the same color, during which time the other rollers are held away from the drum by the cam arrangement.

It will be seen from the foregoing that the rollers cover and ink in sequence each color block which in turn impresses its design on the article to be printed.

While the preferred embodiment of the invention has beenv disclosed, it is understood that minor changes in the details of construction, combination and arrangement of co-operating elements may be resorted to within the scope that is claimed without departing from the spirit of the"'invention.

Where square or irregular shaped articles are whereby an imprint is made chucks are rotated :o be printed, and where the printing is on a fiat surface, the article is brought into printing position by means of the spaced discs and the engaging chucks as previously described, and thereupon the article remains stationary. The printing frame also is stationary and the squeegee is caused to move back and forth over the bottom of the printing frame thereby causing an imprint to be made upon the article.
