18 Claims.

Our invention relates to a machine for printing on spherical objects and'particularly to a machine of this character for printing on balls such as baseballs, soft balls and the like.

So far as we are aware, the printing on baseballs and the like has heretofore usually been applied with hand stamps with the result that the printing is, in most instances, far from perfect. Furthermore, since a different printing must be applied to different zones of the balls, a plurality of hand stamps is required; the printing is a comparatively slow process; and, due to the time involved, the cost is high.

The principal object of our invention is to provide a mechanical device for printing on spherical objects, such as baseballs and the like. Another object is to provide a device of this character in which the quality of the printing is far superior to that which can be applied with hand stamps. Another object is to provide a device which, when a ball is placed therein for printing, will automatically and quickly apply the required printing to different zones of the ball. Another object is to provide, in connection with our device, a conveyor which will receive the balls as they are dropped from the device after the printing operation and carry them away while the ink thereon is drying.

We accomplish these objects by means of the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawing, in 'which- Fig. l is a more or less diagrammatic perspective view, with portions broken away, of the principal features of our device;

Fig. 12 is a fragmentary perspective view of a detail; and a Fig. 13 is a side elevation view, partially in section, of the conveyor, and might be considered a part of Fig. 4. v Referring to the drawings and first to Fig. 1,

for a general understanding of the device, I is a table top which is supported on suitable legs, such as shown at 3 in Figs. 4, 6 and '7. 4 represents generally a clutch for holding the balls to be printed and which may be thrown into or out of engagement with the ball by means of the handle 5. 6 is a slide carrying at one end stamps or electrotypes, such as shown at l and 8, having spherical printing surfaces of a radius equal to the radius of the balls to be printed, and bearing the matters to be printed thereon. The slide 6 is reciprocated by means of the cam follower 9 connected thereto, and which rides in the cam slot Ii] in cam cylinder H. The cylinder II. is rotated in the direction of the arrow shown thereon by means of a motor l2, shown in Figs. 2 and 6, through a speed-reducing device, a chain and sprockets, and a one-revolution clutch represented generally at l3. Attached to the slide 6, and moving therewith, are two, parallel-disposed racks I 4 and [5 which cooperate with gears l6 and I! attached to the clutch elements [8 and [9, respectively, and which serve to turn the ball held in the clutch elements to present different surfaces thereof to the electrotypes. 20 represents generally the device for inking the types. 2| is a solenoid which serves to snap up the finger 22 into contact with a hinged portion of the slide 6 which carries the electrotypes and which serves to bring the electrotypes into printing. contact with the ball. 23 is another solenoid which serves, at time spaced intervals, to pull the inking device 2|] into contact with the electrotypes, and 24 represents generally a conveyor having rings 25 thereon into which the balls are dropped after they are printed and the clutch 4 is opened.

As illustrated in the drawings, the slide 6 (see Fig. 4) rides on rails 26 and 2'! (see also Figs. 3, 6, 7, 8, 9 and 10) The slide 6 comprises a section 28 which is normally held to the rail 26 by an overhanging fiange 29, and a section 30, bearing the electrotypes I, 8 and 3|, which is pivotally connected to the section 28, as shown at 32 in Fig. 4. When the solenoid 2| is energized, as shown in Fig. 4, the armature 33 thereof is drawn downwardly from the position shown in Fig. l to the position shown in Fig. 4. This pulls the lever 34 downwardly and kicks the finger. 22 upwardly against the bottom of section 38 of the slide to bring the stamps, or electrotypes 8, l and 3|, into printing contact with the ball in sequence and in the order name-d. In Fig. 4, the stamp 3| is shown in printing contact with a ball 35.

In order to bring the stamps in sequence into printing position with respect to a. ball 35 held k in the clutch, the large cylinder or cam l I, having 3 the cam slot l9 therein, cooperates with the follower 9 which is attached to the section 28 of the slide. The cam slot I is provided with the required number of dwells, such as 35 and 57 in Fig. l, to hold the stamps, etc., momentarily be.

neath the ball 35 while they are being brought into printing contact with the surface of the ball by the upward movement of the finger 22, and also with another short dwell (not shown) to hold the slide stationary during the operation of the inking mechanism described below which takes place when the cam cylinder is stopped or is stopping after one revolution.

The racks M and 15 which cooperate with the gears I and ll, respectively, and which move and stop with the slide 5, turn the clutch 4, and the ball 35 therein, about the transverse, horizontal axis of the ball, and thus serve to bring diiferent surfaces or zones of the ball, in sequence, into position to be contacted by the stamps.

In order to apply ink to the stamps between each sequence of printing operations, we provide an inking mechanism represmted generally by the numeral 23; reference being had to Figs. 1, 2,

i 3, '7, 10, and 11 in connection with the following description.

Pivoted at 39 to uprights 49 and 49 secured to the table top 1 is a pair of spaced, parallel-disposed levers M and 33, having vertically-extending plates 45 and 35 secured thereto between which the inking mechanism is mounted. This mechanism, as illustrated, comprises an upper pulley 45 having an elongated cylindrical, peripheral surface and which is fixed to the shaft ll mounted in bearings in the plates at and E5. Mounted on one end of this shaft is a gear 45 in mesh with a pinion '59 which is driven by a shaft 50 through a speed-reducing mechanism 52 by the motor 52.

Mounted on a shaft 53, having its axis in substantially vertical alignment with the longitudinal center line of the slide 5, and when said inking mechanism is in contact with said stamps, passing through the centers of the spheres of which the surfaces of the stamps l, 8 and Si are a part, are three lower pulleys 54 having spherical, peripheral surfaces, conforming in shape to the equatorial zones of the spheres of which they are a part, and which have equal radii slightly less than the radii of the balls to be printed and the radii of the spherical printing surfaces of the stamps. Connecting the pulley 55 to the pulleys 54 are three inking belts 55 formed of resilient material such as rubber or neoprene. Rubber idler rolls 55 and 5? serve to maintain the belts 55 taut and in contact with the pulleys 45 and 54.

From the foregoing, it will be apparent that the portions of the belts 55 in contact with the pulley 45, are cylindrical, but where they are in contact with the pulleys 54, the surfaces thereof are spherical in shape and of a radius substantially equal to the radius. of the printing faces of the electrotypes 1,8 and 3t. Inking rollers 58 and 59 run in contact with the cylindrical portion of the belts on the pulley 45 and are held in yielding contact with the belts by means of the spiral springs 60, one of which is shown in perspective in Fig. 12, and others of which are shown in Fig. 6. Anysuitable means, such as a brush, absorbent wicks or pads, for applying ink to the rollers 58 and 59 for transfer to the belts 55, may be used, but are not shown in the drawings. In order to rollers 58 and 59 are oscillated axially by a cam H2 on shaft 47 (see Figs. 3, 7 and 10) which oodistribute the ink uniformly over the belts, the

operates with the ends of the shafts on which the rollers 58 and 59 are mounted; said shafts being held in contact with the cam by flat springs H3 bearingagainst the opposite ends of said shafts, as shown in Figs. 6 and 10.

Normally, the spherical portions of the belts on the pulleys 53- are held just above and out of contact with the printing surfaces of the stamps by means of the spring 6| shown in Figs. 1, 3 and 7. In order to bring the ink belts into contact with the stamps, the pivotally-mounted levers 42 and 43, to which the inking mechanism described above is attached, are pulled downwardly by the solenoid 23 through the rod 62 which is connected to the lever 63 pivoted to the frame of the device at 54 and connected to the armature of the solenoid 23. This downward movement of the inking mechanism pulls the gear 58 out of mesh with the pinion gear 49. The downward movement of the inking device is a very quick movement and the gear 43 can be momentarily moved out of mesh with the gear 49 without producing any harmful effect.

In order to hold the balls 35 during the printing operation, the clutch mechanism, generally designated by the numeral 6, is employed. This mechanism is well illustrated in Figs. 1, 3, 6, 8 and 9 and will now be described.

The clutch elements ll, l8 and 19 are provided with opposed, spherical, ball-engaging faces 65 and E55, and are secured to the gears I! and I6, respectively, by set screws 68 and 61, or other suitable means. The clutch element l8 and,the gear 16 are mounted on a hollow shaft 69 which in turn is-mounted in bearings 10 and H on the sliding base 72, perhaps best shown in Fig. 1. An additional function of the hollow shaft will be explained below. The clutch element [9 and the gear ll are mounted on a second hollow shaft 13 Which is also mounted in bearings 74 and.'l5

on the sliding base 16.

In order to move the clutch elements 18 and I9 into and out of engagement with the ball 35, a pair of cams I! and 13 are mounted on a transversely-extending shaft '59 which is supported in the bearings 89 and 8E. The cam Tl is provided with a helical slot 82 therein and the cam 18 is provided with a helical slot 83. Cam followers 84 and 85, respectively, are attached to the bearings M and H3, respectively, and a cam-operating handle 5 is attached to the shaft 19. In order to disengage the clutch from the ball, the operating handle 5 is pushed in a counter-clockwise direction as viewed in Fig. 1 which causes the slides 72 and (6, to which the clutch elements are attached, to separate and release the ball. When a ball to be printed is placed between the clutch elements, they are brought into engagement therewith by pulling the operating handle 5 in a clockwise direction as viewed in Fig. 1.

In order to reciprocate the slide 6 and also to control the operation of the solenoids in proper timed relation to the various positions of the slide, the cam cylinder ii is rotated by a motor i2 through a speed-reducing mechanism 86 (see Fig. 6) driven by a belt sprocket 8?, chain 98, and sprocket 89 associated with the one-revolution clutch mechanism Hi. When the device is in operation, the motor is running continuously and the clutch members, one of which is understood to be associated with the sprocket 89 and the other of which is understood to be associated with the shaft I01 of the cam cylinder H, are thrown into engagement by means of the foot, pedal 99 shown in Fig. 6. The clutch mechanism causes absence the cam cylinder II to make one complete revolution and is then automatically thrown out of engagement therewith.

One revolution clutches of the type here employed are well known in the mechanical arts and no claim-is made to any novelty therein. For these reasons, no detailed description of the clutch seems necessary. However, clutches of this type are available in the open market and one type thereof is disclosed in Dickens Patent No. 2,140,737 of December 20, 1938.

In order to stop the rotation of the cam H substantially simultaneously with the disengagement of the driving clutch I3, a Prony brake 9| operates in frictionalcontact with a drum 92 on thecam cylinder II. and applies a drag thereto. The pressure of said brake on the drum may be adjusted by means of the nut 93 shown in Fig. 1. 9

Referring now moreparticularly to Figs. 1, 2 and 4, the mechanism for. controlling the operation'of the solenoids 2| and 23 will be explained.

It will be apparent from the position of the parts shown in Fig. 4 that the slide 6 is in its furthermost position to the right and that the stamp or electrotype 3| is in contact with the 6 In order automatically to convey the printed balls away from the machine after each printing operation, a conveyor, represented generally at 24, is provided, and its construction will be best understood from a consideration of Figs. 1, 6 and 13. Referring particularly to these figures, a

, sprocket IE2 is mounted on a shaft I93 which is ball. In Figs. 1 and 2, it will be assumed, since the section of the slide 6 has not been kicked up, that the solenoid 2| has just been energized and is about to act to move the finger 22 into contact with the bottom of the section 30 of the slide to bring the stamp 3|, which is not visible in Fig. 1 because it is under the ball, into contact with the ball. ,To accomplish the upward movement of th section 30 of the slide 6 at the time when each of vthe stamps 8, I and 3| is precisely in the proper position with relation to the ball, the cam cylinder ,II is provided with three circumferentiallyspaced projections 94, 95 and 96 which are perhapsbest shown in Fig. 2, but are also shown in Fig. 4. In order to actuate the inking mechanism, when the slide 6 is fully retracted to the left from the position shown .in Figs. 1, and 4, the cam cylinder is also provided with another projection9'l (see Figs.,2 and 5).

Positioned to cooperate in sequence with the projections 94, 95 and 96, is an electric switch 98 adjacent the cylindrical cam II; positioned to cooperate with the projection 91 in a second switch 99 also adjacent the cam II. When any of the projections 94, 95 and 96 are in contact with the resilient arm of switch 98, as shown in Fig.5.. 1 and 2, the switch is closed which energizes solenoid 2| by connecting it to the power lines I09 and IDI. The energization of solenoid 2| snaps the finger 22 up against the bottom of the hinged section 30 of the slide 9, at which time the center of one, of the stamps is under the ball in the clutch 4 and lying on the arc of a circle, having --its center in the axis of the pin 32 which pivotally connects the sections 28 and 30 of the slide 6 together, and which passes through the center of the ball in the clutch. The stamp is thus brought into. printing contact-with the ball; it being understood that the center of the ball and the center of the spherical surface of the stamp are substantially coincident when the stamp is in contact with the ball.

7 When the projection 91 on the cam cylinder I I -comes in contact with the resilient arm of switch 99, the switch is closed, thus energizing solenoid 23 which pulls down the inking mechanism 29 p to contactwith the stampsor electrotypes and ap licant ther t Y supported in suitable bearings in the frame of the machine; one being shown at I94 in Fig. 6. The shaft I03 has aifixed thereto a gear wheel I95 which is in mesh with a spur gear I96 attached to the shaft I01 of the cylindrical cam II. Thus, when the cam II is turned, the sprocket I02 is turned. Cooperating with the sprocket I02 is a conveyor chain. I08 which has the ball-receiving rings 25 affixed thereto at spaced intervals such that, when the cam II stops rotating after each complete turn, one of the rings 25 is stopped in a position disposed vertically below the'clutch 4 to receive the printed ball when it is released from the clutch. When the cam cy1inder is again started to print another ba1l,'the conveyor moves on, and, when it stops, another ring is positioned to receive said ball.

In operation, the operator faces the end of the machine at the right in Fig. 1, and shown in elevation in Fig. 6. Assuming the clutch 4 be open, a ball to be marked is placed between the clutch elements and the handle 5 is pulled in a clockwise direction, as viewed in Fig. 1, to grip the ball between the clutch elements. Where the spherical objects being marked are baseballs, the clutch elements [8 and I9 are provided with inwardlyprojecting indexes or markers such as shown at I09 and I I0, respectively, in Fig. 6 with which the operator may align a seam III of the ball 35 to insure that the proper surfaces are presented to the stamps. After the ball has been engaged by the clutch elements, the operator touches the pedal 90, shown in Fig. 6, which engages the driving clutch and starts the cam cylinder rotating. Assuming that the slide 6 is retracted to the left as far as it will go and the stamp have just been inked at the termination of the prior rotation of the cam I I, and are under the inking mechanism, the cam slot III cooperating with the follower 9 attached to the slide 6 moves the slide to the right until stamp or electrotype 8 is under the ball in the clutch. The first dwell in the cam then stops the forward motion of theslide and the racks carried thereby which have cooperated with the gears I6 and I! to turn the clutch and the ball therein to present the proper surface to the electrotype 8. The projection 94 on the cam cylinder closes switch 98 energizing solenoid 2| and pushing the pivoted section 30 of slide 6 upwardly, thus bringing electrotype 8 into printing contact with the ball. When the contact 94 passes out of cooperation with the switch 98, and this is very quickly, the switch is automatically opened, the solenoid 2| is de-energized, the pivoted section 30 of the slide 6 drops back into its normal position and the cam moves the slide forwardly or to the right, as shown in Fig. 1, until electrotype I is beneath the ball. During this movement of the slide, the racks I4 and I5 tum-the gears II] and I! attached to the clutch elements so that a new surface of the ball is presented to electrotype I when it is under the ball. At this time, another dwell in the cam slot I0 stops the motion of the slide, projection 95 closes switch 98, and the pivoted section 30 of the slide is pushed upwardly to bring stamp I into contact with the ball. When projection 95 passes beyond switch 98, the

switch is automatically opened, the parts returned I to their initial position, and the cam II moves the slide forwardly and rotates the clutch 4, just as described above, until stamp 3| is in position to vmake a printing contact with the ball. When switch 98 opens after projections 96 pass out of contact therewith, the cam returns the slide to its starting position where there is a short dwell, and the cam cylinder stops automatically. At the beginning of the dwell, when the slide has stopped, but before the cam cylinder I I has ceased rotating, projection 91 is brought into cooperative relation with switch 99 to close the same. This energizes solenoid 23 which pulls the inking mechanism down into contact with the electrotypes and releases it by the passing of the projection 91 beyond the switch 99 before the cam cylinder stops rotating.

Printing of the ball has now been completed and it is ready to be released from the clutch, dropped into a ring 25 of the conveyor which is now positioned immediately below the clutch, and to be carried along on the conveyor during the printing operation on the next ball.

It is important that the center of the ball, when the ball is dropped from the clutch, travel in a vertical line passing substantially through the center of the conveyor ring 25 positioned beneath. To insure this precise vertical movement of the center of the ball, we provide means for temporarily holding the ball with its center in vertical alignment with the center of the conveying ring as the clutch elements I8 and I9 are moved out of engagement with the ball and until a clear space through which the ball may fall is provided between the lower portions of the clutch elements.

Referring particularly to Figs. 8 and 9, it will be noted that there is slidably mounted in the hollow shaft 69 a rod H4, and that a similar rod H is slidably mounted in the hollow shaft I3. The ends of the rods adjacent the clutch elements I8 and I9 are reduced in size, as shown at I I6 and I I1, and the opposed, free ends thereof are in contact with the ball 35 when in the clutch. Adjustably mounted on the rod I I4 is a collar 8 and compressed between the collar H8 and the abutment H9 is a helical compression spring I29. A similar collar I2I is adjustably secured to the rod H5 and a helical compression spring I22 similar to the spring I is compressed between the collar I2I and the abutment I23. These springs serve to maintain the opposed ends of the reduced portions H6 and II! of said rods in contact with the ball 35, except as explained below. The function of these rods is to hold the ball precisely centered above the ring in the conveyor beneath the ball when the clutch elements I8 and I9 are withdrawn out-of engagement with the ball by means of the lever 5. By means of the adjustable collars IIS and I2I, the compression of the springs is balanced so that the ball is maintained as just described. Thus, as the clutch elements I8 and I9 move apart, the hollow shafts 69 and 13 on which they are mounted, slide over the rods II and H5, respectively, until the ends of the hollow shafts 69, and 73 contact the collars H8 and IZI, respectively, whereupon the springs I20 and IZI are compressed, as shown in Fig. 9, and the ball is released to drop into the ring on the conveyor.

In order to faciltate the placing of the electrotypes in the slide and the removal therefrom, a hand wheel I24 is provided for manually turning the cam cylinder II to move the slide to its furthermost position to the right, as viewed in From the foregoing, it will be apparent that we have provided a device which, while it has been particularly described with reference to the printing of baseballs, nevertheless may be employed for printing any spherical objects, such, for example, as oranges, grapefruit, tennis balls, and the like. All the operator has to do is to place the object to be printed within the clutch, touch the pedal 90, release the clutch after the object has been printed, which is done very quickly, and repeat the operation on the next object.
