7' Claims. (Cl. 101-101) Y tion to provide a tag marking machine of simple construction for marking tags quickly and accurately without the use of separate type blocks. Y. Another object of the invention is to provide a tag marking machine in which a plurality of marking means are arranged on a turret successively to mark different lines on a tag.

Another object of the invention is to provide a tag marking machine including a turret carrying marking means in which the turret is intermittently turned from one marking position to another and Yisv positively held in each marking position.

A further object of the invention is to provide a tag marking machine including a plurality of suitable marking means such as type wheels on a turret in which the turret may be released at will to facilitate setting of the markmg means.

Another object of the invention is to provide a tag marking machine having a turret carrying a plurality of marking means in which one of the marking means is inked during the time that another marking means is marking a tag.

Another object of the invention is to provide a tag marking machine including a turret movable to diierent positions for diierent marking operations, in which tags to be marked are fed to the machine automatically upon each completed revolution of the turret.v

The above and other objects and advantages of the invention will be apparent from the following description when read in connection with the accompanying drawings, in which:

Figure I is a side elevation of a tag marking machine with parts broken away and in section;

Figure 2 is an elevation at right angles to Figure 1,` with parts in section;

Figure 3 is a partial section on the line 3-3 of Figure 2;

Figures 4 to 7 are views similar to Figure 3,

`porting frame including a base III adapted to rest on a table or other support, and carrying a pair of upright side supports II, spaced apart and extending vertically above the base. A table I 2 is supported by the uprights I I at a point above the base.

The uprights I I, adjacent their uppermost part, support an axle I3 extending from one upright to the other. The axle rotatably supports a turret formed by a pair of plates I4 axially spaced apart to receive type wheels, indicated generally at I5, between them. As shown, iive such type wheels are provided, although it will be apparent that a greater or less number could be utilized as desired.

- As best seen in Figures 3 to 7, the type wheels are not uniformly spaced circumferentially, and furtherQare at slightly diierent distances from the axle I3. In operation, as will be described hereinafter, the turret is turned to diierent radial positions spaced uniformly apart so that when each typewheel is turned to the lowermost position overlying a platen, indicated at I6, the type wheels will be spaced the same distance above the platen, but will engage the platen at different points. Thus, in the position shown in Figure 3, the lowermost type wheel engages the platen in line with a vertical radius from the axle I3. When the turret is turned counterclockwise through one-iiith of a revolution to the position of Figure .4, the lowermost type wheel' willv engage the platen at a p oint to the left of the vertical radius by an amount equal to the desired line spacing. Similarly, when the turretis turned further to the next position, shown in Figure 5, the lowermosttype wheel will engage the platen at a point spaced from the vertical radius two times the desired line spacing. In the fourth position shown in Figure 6, the lowermost type wheel engages the platen al distance three" times the desired 4line spacing from the vertical radius,' and in Figure 7, the lowermost type wheel engages the platen a distance equal to four times the desired line spacing from the vertical radius. It will be apparent that any desired line spacing on either or both sides of the vertical radius could be obtained by proper spacing of the type wheels, and that the arrangement illustrated is only one of the many possible spacings.

The type wheels I5 are mounted on axles extending between the turret discs I4. Each of the type wheels comprises a plurality of printing discs having printing characters formed thereon, and the type wheels may be independently set by a setting member I1, terminating in knurled knobs and adapted to be shifted axially into engagement with the desired type wheel and then turned to set the type wheel. It will be seen that in this way, any desired combination of characters can be quickly and easily obtained, simply by shifting and turning the setting knobs I1.

The turret is adapted to be intermittently driven through the several positions shown in Figures 3 to 7, inclusive, by means of an intermittent drive mechanism shown as comprising a disc I8 rotatably mounted on the axle I3 and rotatable relative to the turret. The disc I8 is formed in its outer face with a series of radial grooves I9, connected` by an open center portion 2 I, there being a groove I9 for each of the printing members. That is, in the machine shown, in which iive printing members are provided, there are five equally spaced grooves I9. Between the grooves I9 the face of the disc I8 is formed with a plurality of. arcuate flanges 22. The flanges 22 are evenly spaced between adjacent grooves and are substantially 108 in extent. Y

The disc is driven by a rotatable driving member 23, mounted on one of the frame uprights II, and having an arm 24 projecting from one side thereof and carrying a roller 25 adapted to t into the grooves I3. Diametrically opposite the arm 24 the` driving. member 23 is formed with a segmental arcuate projection 26 adaptedI to enga-ge4 with the arcuate flanges 22 to lock the disc I8` between the intermittent motions imparted to it by the pin 25. The driving member 23V is driven through a sprocket chain 21, driven through a sprocket 28. The sprocket 28 is connected through a one revolution clutch 2E! with a transmission 3i).v driven by an electric motor 3|. Asbest seen in Figure l, the one revolution clutch comprises an inner driving member 32 continuously driven by the transmission 30 and having a plurality of circumferential notches therein. Around the driving member 32 is a flanged driven member 33,. on which a pawl 34 is pivotally mounted, theY pawlv 34 having` a toothed end adapted to engage in the notches in the driving member. The pawl 34 has a projection 35 at its opposite end, adapted to extend through a slot in the flange-33 and to be engaged by any desired type of releasing trigger (not shown). d

When the projection 35 is pressed inwardly by the releasing finger the pawl will be moved out of engagement with the driving member 32 to interrupttheV drive between the transmission andthe sprocket 28. Upon release of the projection 35, theV pawl will be locked into engagement with the driving member 32 by a spring or the like, so as to connect the driving and drivenmembers. By arranging a single releasing member to engage the projection 35, it will be seen that this projection is always engaged at the same point, so as to disconnect the driving and driven members with' the driven member in the same position.

When the driving member 32 and the driven member 33 are connected, the. driving member 32 will be rotated, causing the. roller 25v to travel in the path of an epicycloid. in the grooves I9 intermittently to rotate the disc I3 through onefth of a revolution. When the roller 25 moves inwardly out of one groove I9 into the central opening 2i, the arcuate projection 23 will move into engagement with one of the arcuate flanges 22 to lock the disc i8 against rotation, it being noted that at this time the roller 25 does not drivably engage any portion of the grooves I9. With this construction, the disc is at all times under the control of the driven member 23, and is held positively against rotation, except when the roller 25 is in engagement with a groove I9 to Vturn the disc.

The disc IS is drivably connected to the turret by means of va clutch mechanism illustrated in Figure 2 as comprising a plurality of pins 36 connected to a sleeve 31, slidably surrounding the axle I3 and upon which the turret is mounted. The pins 36 are normally urged to the left, as seen in Figure 2, by a spring 38. so as to project into pockets 39 in the disc I8, drivably7 to connect the turret and the disc.

In order to move the pins 36 out of driving engagement with the disc, the outer end portion of the upright II, as shown at the right of Figure 2, is formed with a cam groove 4I. A sheet metal cam member 42 is rotatably mounted around the sleeve 31 and is formed with a projection complementary to the cam groove 4I. A nut 43 on the end of the sleeve 31 prevents axial movement of the cam 42 relative to the sleeve. In the position shown in Figure 2, the sleeve 31 is moved to the left with the pins 35 in their driving position. Upon turning the cam lever 42, the nut 43 and sleeve 31 will be cammed to the right to disengage the pins 3G from the sockets 39, thereby to disconnect the turret and the driving disc I8. This construction is highly advantageous for setting the printing wheels I5, since it enables the turret to be turned freely for easy access to the wheels. Upon turning the cam member 42 back to the position of Figure 2, the pins will be moved to tbe left Aby a spring 38, as soon as the sockets 33 register therewith to re-establish 'the driving connection.

The platen I6 referred to briey above is mounted for vertical movement in an opening in the table I2 directly below the turret. The platen is adapted to be moved vertically periodically by means of a lever 44 pivoted on both the uprights II, and connected to the platen by a guide link 45. Intermediate its ends the lever engages a cam 45 connected to the sprocket 28 to be drive simultaneously therewith so that movement of the turret and of the platen are synchronized. In operation, the platen is raised into engagement with the lowermost printing wheel on the turret at times when the turret is locked by interengagement of the segment 25 with one of the :anges 22, so that the turret is held in proper position for marking.

The machine is adapted to mark tags, either in separate form or in a continuous roll, but is shown arranged to mark separate tags which are supported in a holder 41, mounted on the table l2. As shown, the tags 48 are stacked vertically in the holder at one side of the turret, and are adapted to be moved on to the platen by a feeding mechanism comprising a pair of elongated rack bars 49 slidable on the table, carrying a projection 5I to engage the lowermost tag in the stack and move it on to the platen. The rack bars are driven by engagement with a pinion 52 which is resiliently connected through springs 53 with a bar 54 on the end of a shaft 55.

The shaft 5-5 is intermittently driven by a rack 55 engaging a pinion 51 on the shaft, the rack being connected by a link 58 to a gear member 59, rotatably mounted on the frame adjacent the disc I3. The gear 'member is formed throughout the 'major portion of its circumference withgear teeth 6| and has at one point in its circumference a wide-toothed member 62 concavely curved at its circumference. 'Ihe teeth 6l are adapted to mesh with teeth 63 formed on the periphery of the disc I8 and the member 62 is adapted to engage and slide over an arcuate portion 64 on the periphery of the disc. With this construction the* pinion will be rotated once on each complete rotation of the disc, rotation of the pinion, how-- ever, occurring only during a portion of the ro-V tation of the disc to provide an intermittent movement for the shaft 55.

The parts are shown in Figure 1 in a position in which a fresh tag has just been fed on to the platen and the feeding bars 49 have not yet been returned to their initial position.V During the next one-fifth of a revolution of the turret, the gear member 59 will be .turned through one-- lhalf ofv a revolution to raise the link 58 and the rack 56, thus rotating the shaft 55 and the pinion -52in a direction to shift the bars 49 to the left, as seen in Figure 2. At this time the connection between link 58 and gear member 59 is above the axis of the gear member, with the rack in its raised position.

During the time that one of the printing members is printing on a tag, the next printing member to be brought into register with the tag is being inked. For this purpose, an inking pad 65 is pivotally mounted on an axis 66 in a position to engage the printing surfaces of a printing member on the rst station clockwise from the printing station. The inking pad 65 is mounted on a bell crank lever 61, one arm of which carries the inking pad and the other arm of Which'is connected through a link 68 to the lever 44, which actuates the platen. |Ihus, each time the platen is moved upwardly to raise a tag thereon into engagement with one of the printing members, the inking pad 65 will be swung into engagement with another printing member to prepare it for the printing operation.

In operation a plurality of tags are stacked in the holder 41 and the motor 3| is started. The cam lever 42 may be actuated to free the turret I4 so as to permit the sever-al printing rollers to be swung around to a convenient position for the setting thereof by the knobs I1. The cam lever is then turned to its inoperative position so as to allow the pins 3B drivably to connect the turret with the driving disc I8. The tags are successively fed on to the platen I6 by the feeding mechanism described above, and with a tag on the platen and the parts in the position shown in Figure 1, the first printing roller is ready to print. As the motor turns the cam 46, the'` platen will be raised to move the tag into engagement with the printing roller so as to print one line on the tag. As the platen drops, the driving member 23. turning counterclockwise, will move Ithe segment 25 out of engagement with the ange 22, and due to the engagement of the roller 25 with the slot I9 just above the driving member. will rapidly swing the disc I8 and the turret counter-clockwise with the next printing roll in register with the platen. Further rotation of the driving member will move the segment 26 into locking engagement with the next flange 22 to lock the turret against rotation. The platen will then `be raised again to imprint the next line on the tag, the next 'roller in the series simultaneously being inked by the pad 65. This operation will continue until the tag has been imprinted with ve lines, spaced thereon as described above. At the end of the completed printing operation the teeth 63 on the disc i8 will engage the teeth 6| on the gear member 59 and during the next one-fth of a revolution of the turret will turn the gear member to the position shown in Figure 1, to feed a fresh tag to the platen and eject the completed tag. The operation will then continue automatically as long as the clutch mechanism 32--35 remains in engagement. If it is desired to stop the machine at any time, the clutch mechanism may :be disengaged so that the machine will stop in a pre-'determined position.

' Figure 8 illustrates a tag of the type marked by the machine, 4including a substantially rectangular sheet off paper 1|, adapted to have ve lines of marking thereon, as shown. Such marking may include style marking, size -marking, price marking, a code price marking, and lot number marking. It will be apparent, of course, that any other desired information could be marked on the tags.
