15 Claims.

This invention relates to a machine for printing directly upon the surface of glassware, "bak-olite, metal, or any other hard impenetrable sur- The articles formed of such material may be bottles, jars, tumblers, bulbs, cans, and the like. These articles formed of the materials suggested, 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 in one or more colors.

An object of our invention is to provide a machine of the character stated, in which insignia are placed upon articles formed of a hard impenetrable material, without having to print labels on paper or other sheet material, and then affixing 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, and said receiving, holding and printing being done automatically, accurately and with great rapidity.

A feature of our machine is a revolving carrier 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 printing frame and subsequently printed.

Another feature of our machine is to provide a printing frame which will print upon the articles in both directions of its reciprocal movement.

Still another feature is to provide a novel means of operating a squeegee whereby the ink is distributed upon the printing frame in both directions of the movement of said frame.

Another object is to provide a novel means of receiving, and holding the articles to be printed, and revolving said articles-if they are roundsaid 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.

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

Referring more particularly to the drawings, our printing machine comprises a pair of side frame members I, 2. A transverse bed 3 extends between the frame members I, 2. The frame is built up of structural members, such as structural 25 shapes, plates, and the like.

A substantially horizontal conveyor belt 4 extends over horizontal rollersi, 8 and the articles to be printed are rolledonto the conveyor belt, and then move into the machine to be caught by 30 an elevator or rotary conveyor, as will be subsequently described. v

A horizontal shaft 1 is journaled in the frame 1 members I, 2, and this shaft carries a pair of discs 8, 9, secured thereto, said discs being posi- 35 tioned adjacent the frame members I, 2, respectively. Each of the discs 8, 9 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 III which are positioned inwardly of the discs 8, 9. The construction of all of the chucks is identical. Therefore, only one will be described in detail. A chuck on each of the discs 8, 9 is yieldably 45 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 chucks is provided with a trunnion II fixedly attached thereto and journaled in the disc. A coil spring I2 encircles the trunnion and is positioned between the disc and the chuck, thus yieldably pressing the chuck outwardly against Each of the trunnions is formed with a head I2 on the outer end thereof and the head engages a. box cam l3 as the discs rotate, thereby drawing the trunnions and the chucks outwardly to release the bottle. The bottle moves inwardly on the conveyor 4 and is halted by a spring stop finger 4. The box cam l3 terminates at the lower end of the discs so that the trunnion II is released when the chucks in are in the lowermost position. When the trunnion is released, the chucks spring inwardly and hold the bottle which is resting against the stop |4. As the discs rotate, the spring stop |4 yields and permits the bottle to move upwardly past the stop. The cam |3 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 upon a discharge conveyor IS. The discharge conveyor extends around the pulley l8 attached to the shaft 1, and around an idler pulley journaled adjacent the intake end of our machine.

The shaft 1 and the discs 8, 9 are intermittently rotated thru a Geneva gear I 8 on the shaft. This gear consists of a sprocket I9 which is freely rotatable on the shaft 7. A pair of plates 26, 2| are mounted, one on each side of the sprocket l9, and these plates are attached to the shaft 1. Each of the plates 20, 2| is provided with a plurality of outwardly extending pins 22. A chain 23 is formed with a plurality of spaced pins 24 along the length thereof and these last named pins engage the pins 22, thereby rotating the plates 20, 2| and the shaft 1. The chain 23 partly encircles the sprocket |9, and therefore, the plates 20, 2| are only rotated a partial revolution. As the chain 23 leaves the sprocket, the pins 24 will disengage the pins 22 and the plates 20, 2| will then remain stationary.

The chain 23 is driven from a motor 24 which drives thru a reduction gear 25 and thence to a shaft 26. The chain 23 encircles a sprocket 21 on the shaft 26 and also an idler sprocket 28. The idler sprocket is journaled to the frame memher 2 below the Geneva gear IS.

The Geneva gear I8 is only rotated when the pin 24 engages the pins 22, and during the idle period of the shaft 1, the discs 8, 9 are held against accidental rotation by a spring-pressed pawl 29. The pawl drops into one of the notches 30 which notches are properly spaced so that the discs are held stationary when the bottle is in the uppermost position and is being printed.

A rectangular table 3| is reciprocably mounted between the frame members 2. This table fits in longitudinal grooves or tracks 32 in the frame. The table 3| is continuously reciprocated by the following arrangement: A shaft 33 is journaled in the frame members I, 2 and the sprocket 34 is attached to one end thereof. The sprocket.

and the shaft are driven by a chain 35 which 7 chain also encircles a sprocket 36 on the shaft 26.

The shaft 33 is formed with a crank arm 37. A pitman 38 is journaled on the crank arm and to the table 3|. Thus, as the crank arm 31 rotates, the table 3| is reciprocated. The crank arm 31 is slotted as shown at 39 so that the pitman 38 can be adjusted on the arm, thereby varying the reciprocal movement of the table 3|.

A printing frame 40 is adjustably mounted on the table 3| by means of a plurality of clips 4|. The printing frame is adjustable both vertically and transversely of the machine so that the printing can be properly positioned on the bottle. The bottom of the frame 40 is made of cloth, fine mesh wire, or the like, and the 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 42 is adjustably attached to a transverse bar 43 which bar is slidably mounted on a pair of posts 44, 45, said posts being secured in the frame members 2.

Coil springs 46, 46 press against the top of the bar 43, thus yieldably urging the bar downwardly and the squeegee against the bottom of the printing frame.

A pair of fingers 41 are pivotally attached to the bar 43 and these fingers are engaged by cams 48 on the table 3|. As the table reciprocates, the cam 48 engages one of the fingers 41 and raises the squeegee. This raising operation occurs adjacent the end of each stroke of the table. After the cam passes under the table, the squeegee again drops on the bottom of the printing frame and the ink is then transferred from one side to the other of the squeegee so that said ink is evenly distributed on both the up and down strokes of the table.

As the table 3| reciprocates, the chucks H) are rotated by yieldable strips 49 which are secured to the bottom of the table 3|, and the strips 49 press against the chucks when said chucks reach the top of their movement. Thus, the bottle is rotated at the same rate as the reciprocation of the table 3| and the printing operation from the frame 40 is effectively accomplished. It may be desirable to have the stencil slip with respect to the bottle under certain conditions. The flange, while illustrated as being larger than the bottle, might be smaller than the circumference of the bottle. Any slippage that may take place will not in any way cause smearing of the painting material that is applied to the bottle. The squeegee 42 spreads the ink over the stencil and the ink is then transferred thru the stencil to the surface of the bottle. Printing is accomplished on both the forward and backward strokes of the table, and the discs 8, 9 are so timed that a bottle is always in proper position to be worked upon by the printing frame.

As soon as the bottle has been printed, the discs 8, 9 start to rotate, whereupon the trunnions engage the box cam |3 which cam retracts the chucks IO, and the bottle is then released and drops upon the discharge conveyor l5, as previously described.

At the time the upper bottle is being released from the upper chucks, the bottom set of chucks are released from the cam l3 and spring inwardly to grip another bottle. Thus, bottles are continuously engaged and carried upwardly to a printing position, are rotated while in printing position, the printing table moves over the bottle imprinting the insignia thereon and the bottle is released and dischargedall in continuous sequence.
