9 Claims.

This invention relates to printing machines and more especially to .a selector .mechanism for printing machines .of the character used to make impressions from .a series of individual printing .devices which aresequentially progressed through the machine.

'Inthe past, printing machines of the type mentioned have been constructed to print with the selected. printing .devices .and .skip all other devices. TheY selectionlof. the printing devices 'has been made .in various manners, one of which is illustrated in my .copending application, Serial No. 503,160, nledDecember 1'7, 1930. .Such selectors are usually .controlled by suitable indicia s carried by printing devices, such as by removable tabs, notches, openings or the like.

v.'Il'iegeneral object of the present invention is to Aprovide aneriicient arrangement to .enable the printing mechanism -to .print with selected printing .devices and skip the non-selected'printing device, or to skip selected printing devices and VVprint with the non-selected printing devices, as desired.

.A further object is to provide a selector control mechanism which may readily be associated with various types of printing machinesalready in use, as well .as incorporated ininewly constructedmachines.

A .still further object is to provide .a .selector VVmechanism which will coact vmechanically with .the `tabs .or other indicia carried bythe .printing devices, .but which mechanism will .control the operation of the printing machine .through an electrically operated mechanism, which may Vbe readily controlled by tbeoperator .to print or to Vskipselected printing devices as desired.

Other .objects of this invention will become more Yapparent from the following description, which refers to .a lpreferred .embodiment .of the invention as illustrated in the accompanying drawings.

A1l ,to 15, inclusive, .are electrical diagrams illustrating the various .electrical circuits to accomplish theselectionfcr itostopithe machine, asv desired.

. In the accompanying drawings, I .have .illustrated my invention .as embodied in .a ,printing machine which may, for example, be .of the character' disclosed .in my Patent .No 1,930,798, issued .October 17., 1933, Serial No. 503,160, filed December i8, 19.30. Such machine includes .a frame L0, which .supports aprinting .device magazine M, .a .printing `platen .P, together with suitableinechanismto feed printing devices Dacross the table of -then'iachine from the magazine to an anvil U5 located below .the platen. y

In fthe mechanism illustrated in the drawings, the printing Vdevicesare stacked in .the-magazine M by the operator and are successively withdravvnftherefrom andpassed along aguideway `by pawls 2i .suitablymounted onV feed bars 2.2. The feed bars 2.2 .are carried by flanged rollers 23, which kare rrotatable on studs Acarried by the side Wallscf. the guideway. Y l

The feed -bars are `reciprocated `from a .drive `vrockerd which is-rotatablyjournalled onashait .carried by kthemain .fra-me lfrand is .oscillated .in rany well-.known "manner, Pivotally iconnected vto the slide bars .22 by .alink 30 is abell -crank -3 I., `which iismounted on -a .stud 32 :carried by the frame l0. The bell crank 3i isconnected `bya link-33 `to arock arm :34, pivotally mounted konasha'ft .35 carried by the frame 1.0. The rock arm 34 is connected .by a link A36 to the r.driving arm Y2li, heretofore mentioned. '.Ihis arrange `ment `is such that, when the driving .arm ..24 vswings in a clockwise direction theY feed `bars will -be drawn rearwardly toward Ithe left in Fig. 2)., and'when-the rcckarm r2li -is swung in a-.counter-.clockwise .direction .the feed -.bars will be .drawn forwardly (.towardtherig-ht). During the llatteror forward movementkof the -vfeedbars, the pawls 2|y .engage the plates andv advance them stepV by step from the 4magazine to a position above sananvil 40, Yin which ,position the printingdevice DI is shown. f Y The platen P .is of the oscillatorytypeand is vmounted ,so .as to fstrike the printingvdevices, while `theyare at rest -on @the anvil `YMl. .'As shown' in .Fig the platenis Vcarried .on the outermost end ofa-,platen arm 41which ispivotally mounted on the shaft heretofore described. The lower end of r`the ,platen .arm M. is ,provided with a .roller Y1.3 arranged to .coact -with .a .cam ,slot I4 ina leverlli pivotally mountedonitheshaft 25. :15.'5

The oscillating movement of the driving arm 24 is imparted to the platen driving arm 45 through the medium of a latch 41, which is 0perated by a selector mechanism hereinafter more fully described. Consequent upon the clockwise movement of the driving arm 24, the movement of the arm 45 and its cam 44 swings the platen in a clockwise direction toward the anvil 40' and an impression is made from the printing device through a suitable inking ribbon, not shown.

As shown in the drawings, the selector mechanism includes a detector carriage 50, arranged to operate upon the printing devices when they are in the position of the device D2 of Fig. 2, which position is immediately preceding the printing position indicated by the device DI. As shown Vin the drawings, the detector is in the nature of a bail overhanging the guideway 2| and pivoted to a shaft 52 carried by the frame. The arrangement is such that the detector carriage 50 projects over selector tabs T which are carried on the far end of the printing devices, as shown in Fig. 5.

The .detector carriage 50 includes a plate 53 provided with a series of openings 54, there being shown four openings arranged above each possible position of the tabs, which are removably positioned in notches I1 of the printing devices. Pins 55 may be selectively inserted in the openings 54 and retained in place therein by a cover plate, the pins depending below the lowermost surface of the carriage. The detector unit 50, the carriage together with the pins 55 are urged downwardly as a unit by a compression spring 60, which is interposed between the carriage 50 and a rock arm 56, and is engaged once in each cycle of operation by a pawl 51 pivotally carried by the rock arm 34 heretofore mentioned.

The selection is made by oscillating the carriage 50, causing it to move downward. If, on this downward movement, one of the pins 55 strike an abutment on the tab, further downward movement of the carriage is prevented and the selector mechanism operates to position the latch 41 to produce the desired effect as to the printing or skipping of the selected printing device.

'Ihe latch-mechanism 41 controls the operation of the platen, but has no effect upon the plate feed members 22. This latch comprises a latch member 10, pivoted at 1| to the driving arm 24, and normally retained in an uppermost or normal position, the end 15 thereof engages a block 16 carried by the cam arm 45.

When the driving arm 24 is returned or moved in a counter-clockwise direction, it carries with it the cam arm 45. e To this end, a block 16 is secured to the forward (right hand) face of the arm 45 and extends beyond its farthest face into a slotted opening 8| in the arm 24 a distance sufficient to be engaged by the end surface of the slot 8| in the arm 24. Hence, when the arm 24 moves in a counter-clockwise direction the cam arm 45 will be positively drawn in a counterclockwise direction by the driving arm'24.

The latch member 10' of the cam arm clutch 41 is operated by a roller 90 carried by a lever arm 92. When the arm 92 is swung in a clock- Wise direction it acts to cam the latch member `(Fig. l).

I I 0 mounted on the frame I0. As shown in Figs. 1 and 2, the arm 92 is rigidly secured to a transverse shaft IOI, which is rotatably mounted ln the frame I0. Rigidly secured to this shaft is a bell crank II4, one end of which is drawn into engagement with a roller II5 carried by a bell crank I 6, hereinafter to be described more fully. To maintain contact between the arm I I4 and the roller II5, the other arm of the bell crank I I4 is connected by a spring I I1 to the frame I0. In the position of the parts shown in Fig. l, the roller II5 rests on the upper surface |20 of an arm I 2|, pivoted at |22 to the frame |0`, and normally swung in a clockwise direction by a suitable tension spring |23. The movement of the arm |2| is limited by suitable stops |24.

During the time when the selection of the printing device is made by the detector 50, the bell crank II 6, which is pivoted to the frame I0 at |25, is struck by a pawl |30 carried by the rock arm 34, heretofore mentioned, and the bell crank II6 is swung in a counter-clockwise direction. As the `bell crank swings, it raises the roller II5 out of contact with the arm |2|, permitting the spring |23 to swing the arm |2| in a clockwise direction to contact with the left hand pin |24 If, at this time, the detector member has been positioned so as to energize a solenoid I I0, as hereinafter more fully described, a plunger I3I of the solenoid will strike an arm |32 of the member |2|, causing it to swing in a counterclockwise direction, and, as the pawl |30 passes over the shoulder |33 of the lever IIS, the lever will be drawn downwardly through the action of the spring I I1 and the bell crank I I4. This will cause the roller to rest upon the surface |20 of the member I2 I, in which position the lever 92 will remain as shown in Fig. 2, and the latch mechanism will operate to maintain the driving connection between the driving member 24 and the cam arm 45.

If,V at the time the bell crank I I6 is swung clear of the member I2 I, the detector member 50 should be so positioned that it would not cause an energization of the solenoid I I0, the spring |23 would `maintain the member |2| swung in an extreme clockwise direction, in which instance an upwardly extending projection I 36 of the member |2| would lie beneath the path of the roller I|5, and when the pawl |30 disengaged the shoulder |43 of the lever |06 the compression spring |23 would maintain the member |2| in its extreme clockwise position and the roller II5 would rest on the upper surface of the projection |36, causing the bell crank I I4 to be maintained in its extreme clockwise position. This will cause the arm 92 to be in such position that, upon return lmovement of the driving arm 24, the roller of the arm 92 would strike the raised surface |31 of its latch member 10, causing the driving connection of the latch 41, between the driving member 24 and the cam arm 45, to be broken. This, of course, would have noeffect upon the plate feeding mechanism, which would continue to function as long as the driving arm 24 was operating.

There are two positions in which the detector 50 may be stopped. Its downward movement may be stopped by contact of one of the pins 55 with thesurface TI of the tab, or by contact with the tab between a pinand a raised surface T2 of the tab. I have so arranged my mechanism that these positions of the detector 50 operate certain electric switch members to operate the solenoid IIO so as toprint a selected plate and skip all other plates, or to skip the selected plate and print The circuits of the operation just referred to are illustrated in the diagrams of Figs. 14 and 15. When the operator desires to skip the selected plate, the switch 300 is moved from Contact with the switch 2|2 into contact with the'switch 222, making the circuit from the solenoid H pass through the switch 222, rather than through the Y switch 2|2, as heretofore described. Therefore, the switch 2I2 will not be considered in connection with the operation of the mechanism with this position of the switch 308.

Under the above conditions, when the detector 5l) descends, the pins thereof failing to strike a raised portion of a tab, the position of the detector unit is the same as heretofore described in connection with Fig. 10. The switch operating pins will be moved to the same relative position as they were when the switch member 300 was contacting with the switch 2|2. However, the switch 222 will have been closed and the circuit is therefore made through the timing switch 202, the switch 222 and the manually operable switch 300, to the solenoid I I0, energizing such solenoid. This causes the arm I2I to be swung in a counterclockwise direction, which results in maintaining the driving connection between the arm 24 and the arm 45, and the platen will therefore operate to make an impression from the printing device on the next succeeding cycle of operation.

Assuming that the switch 300 still remains in Contact with the switch 222, and a printing device having a raised portion of a tab thereon is positioned beneath the path of the detector 53, the detector member will be stopped short of its full stroke, and the position of the switches will be as illustrated in Fig. 15. In this position it will be noted that the switch member 222 has not been closed. Therefore, the circuit between the closed timing switch 202, the manual switch member 300 and the solenoid H0 is broken at the open switch 222 and the solenoid will not operate. The driving connection between the driving arm 24 and the driving arm 45 is therefore broken, causing the platen to fail to function on the next cycle of operation but permitting the printing device feed to function as usual.

From the foregoing description, it is readily apparent that I have provided a selector device which may be used in conjunction with a printing machine, together with a plurality of individual printing devices having indicia selectively positioned thereon, such as tabs, which selector may be readily controlled by the operator of the machine, so as to cause the apparatus to function to print the selected units and skip the non-selected units, or to print non-selected units and skip selected units.
