24 Claims. (012101-57) This is a division of my application, Serial No. 469,953, filed July 23, 1930;

This invention relates to printing machines of the kind wherein a plurality of printing devices 5 are introduced into a magazine and from which they are withdrawn and fed through printing position, whereat impressions are made therefrom, and then to a galley wherein the printing devices are collected in the same sequence as that in which they were arranged when introduced into the maagzine whereby the collected printing devices may be removed from the galley and stored in drawers of storage cabinets until they are to be used again.

The printing machines are ordinarily so arranged that the printing devices move therethrough in a step-by-step manner and an impression is made from the printing device at printing position during an at rest interval in the step-by-step movement. Not all of the printing devices moved through printing position are always used in a printing operation and a selector mechanism, which cooperates with identifying means on the printing devices, determines which of the printing devices are to be used in a printing operation. Often it is desired to make more than one impression from the printing devices from which impressions are being made and to this end the step-by-step movement of the printing devices is interrupted while the platen of the machine is making the desired number of impressions after which the step-by-step movement of the printing devices is resumed.

Among the objects of my invention are to in-' the selector mechanism while multiplicate impressions are being made from a printing device and to render the selector operative as the last of the multiplicate impressions is being made; to constantly operate the driving device for imparting a step-by-step movement to the printing devices but to provide a portion separable from the constantly driven device so that the step-bystep movement of the printing devices is interrupted without altering the constant operation of said driving device; and to provide for multiplication by a simple and economical construction of efficient and positive operation and which may be readily installed in printing, machines of various designs without requiring extensive altertions therein.

Fig. 2 is a transverse sectional view of the printing machine as illustrated in Fig. 1;,

Fig. 3 is'a plansectional view taken substantially on the line 33 on Fig. 4;

Fig. 4 is a fragmentary rear elevation;

Fig. 5 is a sectionalview taken substantially on the line 5-5 on Fig. 4;

Fig. 6 is a fragmentary detail view of a shifting mechanism; and Fig. '7 is a fragmentary detail view of a portion of the controlling device forming the --subject matter of this invention. 1 I have illustrated my invention in associa tion with a printing machine embodying a jack shaft 8 having a pulley arrangement 9 or other suitable power'receiving device fast thereon to which movement is imparted from a suitable source of power such as an electric motor (not shown). On'the jack shaft 8 is a pinion 10 meshed with a spur gear 11 rotatable on the main drive shaft 12. A controlling rod 13 is provided for engaging the clutch 14 to connect thespur gear 11 to the shaft 12 whereby movement imparted to the pulley 9 will be transmitted through jack shaft 8, pinion 10, spur gear 11 and clutch 14 to said drive shaft 12. The jack shaft 8 and the drive shaft 12 are journaled in suitable-bearings in the frame 15. The table or bed 16 of the machine is mounted at the upper end of this frame. At one side of the machine and carried by the bed 16 is a magazine M into whichprinting devices D are introduced and from which the printing devices are successively withdrawn and fed to printing'position above an anvil whereat impressions are made therefrom by the platen P through a suitable ink ribbon (not shown). The platen P is mounted at the lower end of the housing 17 at the outer end of the platen arm 18 pivotal about the shaft 19 carried by the frame of themachine. Formed as an extension of the platen arm 18 is an arm 20 which depends below the shaft 19. At the lower end of thearm 20 is'a half-round lug 21. An arm 22 is'pivotally mounted at 23 on a bracket 24 depending from the bed 16.. A notch 25 is provided in the upper edge of the 'arm 22 and the lug 21 seats in'this notch :to latch the platen in its upper or nonprinting position,-as shown and described in my co-pending application, Serial No. 572,489, filed November 2, 1931.

In my co-pending application, Serial No. 469,953, filed July 23, 1930, I have described a selector mechanism for controlling the operation of the platen from the printing devices. This selector mechanism includes a head H wherein a plurality of detecting fingers F are mounted and which are positioned by engagement with identifying characteristics on the printing devices. When the fingers are positioned they cooperate with a matrix to regulate the positioning of'the arm 26 which, in turn, regulateslthe positioning of the arm 27 which has an upstanding portion 28 at the free end thereof on which there is a triangularly shaped lug 29. Pivotally mounted at 23 is a vertically extending arm 30. having a notch 31 therein and a formed end portion 32. A triangular portion 33 is defined between the notch 31 and the forward end 32 and the apex thereof lies in the plane of the front edge 34 of the portion of the arm below the notch 31, Whenever the arm 26 isso positioned that the upwardly extending portion 28 of the arm- 27 is so located that the triangularly shaped lug-29 seats on either the edge 34 or the apex of the projection 33, the arm 30 is pivotedinto 1 the position shown in Fig, 2 and the arm 35,

connected to the arm 30, is also pivoted. A spring 36 extends between the arms 22 and 35 and when the arm 35 is pivoted as described, the spring 36 is tensioned whereby the arm 22 is moved downwardly and the notch 25 isretracted from engagement with the lug 21 whereupon the arm 18 is free to pivot about the shaft 19 so that the platen P will move toward printing position. Should the triangular-1y shapedportion 29 be .positioned in either the notch 31 or along the formedend 32, the spring 37 will act on the arm 22 to pivot it into an upper position whereat the lug 21 will seat in the notch 25 to latch the platen in its upper or non-printing position. When the platen arm is released in the manner described so that the platen may move toward printing position, impression pressureiwill be imparted to the arm at the time the platen moves into a predetermined position. To, regulate the time at which impression pressure will be imparted to the platen, I provide an arm 38' having a cam surface 39 thereon. A dog 40; is pivotally mounted at 41 on the arm 20 and the nose 42 of this dog travels along thecam surface 39 as the platen P moves toward printing position and at the time the platen P moves into a predetermined position relative to the printing device D in printing position, the nose 42 reaches the end of the cam surface 39 and the spring 43 acts to pivot the dog whereby the shoulder 44 thereon moves into the line of movement of the shoulder 45 on the arm 46 unitary with the clamp strip 47 surrounding the eccentric 48 fast on the main drive shaft 12, for at the time the platen P is moving toward printing position the eccentric operates to move the arm 46 outwardly awayfrom the shaft 12. As soon as an impression has been made by the platen P the hooked end portion 49 on the arm 46 engaging a boss 50 on thearm 20 moves the platen P away from printing position into its upper or non-printing position for at this time the eccentric is moving the arm 46 toward the shaft 12. A. platen operating mechanism-of the foregoing type is preferablyemployedin the machine because it affords a safety in that printing pressure is not applied to the platen until the time it is in aposition so close to the printing low the guideway 51 is a center bar 52 having a plate 53 on the upper edge thereof on which the printing devices D rest during movement from the magazine through printing position and to the receiving. galley, and this plate is preferably of a width equal to the distance between the spacing flanges on the printing devices so that the printing devices will neatly fit on the plate during movement therealong. Extending in juxtaposition to the center bar 52, on each side thereof are rails 54 and 55 and mounted inwardly of the rail 54 is a slide bar 56 having driving pawls 57 mounted thereon which are urged upwardly by springs 58. At therear end of the slide bar isa shoulder 59 which engages the lowermost of the printing devices in the magazine M and as the slide bar moves toward the left, as viewed in Fig. 1, the lowermost of the printing device is moved from the magazine onto the plate 53. The surface of the slide bar56 behindthe shoulder 59' is in a plane above the remaining portion thereof, and. this surface holds the printing devices in the magazineabove the lowermost printing device against displacement as the shoulder 59 moves said lowermost printing device onto the plate 53. The slide bar receives a reciprocatory movement and the pawls 57 engage the printing devices during movement of the" slide bar to the left in Fig. 1 to advance the printing devices toward printing position and the receiving galley. When the slide bar moves toward the right as viewed in Fig. 1, suitable stop pawls (not shown) engage the printing devices to hold them against movement and the pawls 57 are cammed downwardly against the action of the springs 53 and pass below the'printing devices so that when movement of the slide bar to the right is completed each of the pawls will have moved the entire length of one printing device and will have been moved by the springs 58 into engagement with the end of the printing device behind that previously engaged thereby and under which they have just moved.

The slide bar, as has been stated, has a reciprocatory movement imparted thereto. One end of a rod 60 is connected to an arm 61' pivotally, connected to the slide bar at 62. The other end of the rod is pivotally connected to the upper end of a rocker 63 mounted onrthe stub shaft 64 journaled in a portion 65 which is a part of the bracket 24. Another rocker 66 (Fig 3) is fast on the: stub shaft 64 adjacent the rocker 63'. On the rear face of the rocker 66 and at the edges are projecting flanges 67 and68 which provide a trackway 69 therebetween'. Disposed in this trackway is a roller 70 carried by the crank 71 mounted at the end of a shaft 72 journaled in the bracket 24. On the shaft 72 is a bevel gear 73 meshing with a bevel gear 74 fast on the main drive shaft 12 and when the main drive shaft 12 is rotated movement is transmitted through the bevel gear 74, bevel gear 73, and shaft 72 to the crank 71 and as the crank 71 rotates the roller 7.0 reciprocates in the guideway 69 and imparts a rocking movement to the rocker 66. On the rocker 66 is a projecting lug which extends past the edge of the rocker 63. Pivotally mounted at '76 on the rocker 63 is a pawl .77 having a notch '78 therein. adapted'to engage the lug 75 to thereby interconnect the rocker 63 to the rocker 66, a spring '79 holding the notch in engagement with the lug. So long as the notch 78 is engaged with the lug 75, the rocker 63 will rock with the rocker 66 and this rocking movement will be imparted through the rod 60 and arm 61 to the slide bar 56 whereby theprevious- 1y referred to reciprocatory movement will be imparted to said slide bar. When morethan one impression is to be made from aprinting device the operation of the means feeding thev printing devices is interrupted and this may be conveniently accomplished by disengagingthe notch '78 from the lug 75 without interrupting movement of the rocker-66. To this end anarm 80 is pivotally. mounted .at 81 on the bracket24. A pin 82 is mounted at one end of the arm 80.and rests on the inclined pin 83. A rod 84-is passed through the pin 82and aspring 85 is disposed about this red between the pin 82 and the adjusting nuts 86 at the outer end of the rod. The rod 84 may be extended to a manually operated lever whereby when the rod is depressed the pin 82 will act on the pin 83 to pivot the pawl '77 whereby the latch '78 will be disengaged from the lug 75. This arrangement is employed when it is desired to manually interrupt operation of the printing device feeding mechanism. However, means to be described hereinafter and cooperating with the arm 80 function to automatically disconnect the printing device feed when multiple impressionsare to be taken from a printing device.

' The present machine is arranged so that consecutive, duplicate, triplicate, or quadruplicate impressions may be taken from each printing deviceand while I have shown an arrangement limited to the making of quadruplicate impressions it is tobe understood that an arrangement for making a greater number may be provided if so desired. Suitably supported on the bracket 24 is a stud 8'7 carrying a shaft on which'a plurality of peripherally notched discs are rotatably mounted. These discs are rotated by a pawl 88 pivotally. mounted on the outer end of an arm 89 having a bearing portion 90 through which the shaft 19 is extended. Depending from the bearing portion 90 is a boss 91 and a spring 92 extends between the bracket 24 and the boss 91, and this spring urges the arm 89 upwardly. An adjusting screw 93 is'mounted in the arm 89 and has a lock nut 94 thereon. .The free end of the adjusting screw 135 engages one edge of the arcuate arm 95 (Fig. 4) that is connected to and extends at ri ht angles from the platen arm 18 and about the shaft 19. When the platen moves downwardly, aspreviously described, an edge of the arcuate arm 95 engages the screw 93 and pivots the arm 89 downwardly against the action of the spring 92. A spring 96 extends between the pawl88 and the arm 89 and urges the free end of the pawl into engagement with a shield 97 carried by the bracket 24 and disposed over the peripherally notched discs mounted on the shaft 8'7. In the present instance, where the device isarranged for consecutive, duplicate, triplicate, and quadruplicate, operation of the platen, threesuch discs are provided and these discs are indicated by 98, 99 and 109, and the. shield 97 is slightly wider than the three discs and the-spacing therebetween. The disc 98 is engaged byfthe pawl 88 whenduplicate impressions'are to be made from a printing device and in the present construction of the machine this disc has twelve notches in the periphery Y thereof. .The' disc 99 is used when triplicate impressions are to be made from a printing device and has eighteen notches in the periphery thereof- The disc 100 is used when quadruplicate impressions are to be made from a printing device and this disc has twenty-four notches in the periphery thereof. ."Ihe pawl 88 rests on the shield 97 and this shield is used to withhold the pawl from engagement with the notches in the disc until a certain time, for when the pawl engages the disc 98, having twelve notches therein, 'more movement is imparted to the disc than is imparted to the disc 100 when it is engaged, for. this disc has twenty-four notches therein;

therefore, the portion of the shield aligned with the disc 98 is cut away, as indicated at 101, to permit the pawl to engage the disc 98 near the start of an operation of the pawl and to continue in engagement during most of the period of operation; The shield 9'7 is also cut "away, as indicated 'at 102, in alignment with the disc 100, but as a smaller portion of the shield is cut away in this instance the pawlwill only engage the disc for a short period during its operation.

Intermediate the cut-away portions 10land 102 the shield is cut away, as indicated at 108, and

this cut-away portion permits the pawl to-engage the disc 99 for a period longer than itengages the disc 101' but not as long as it engages the disc 98. The remaining portion 104 of the shield is not cut away and, therefore, when the pawl is aligned with this portion ofthe shield it will merely ride thereover and will not engage any disc, and this arrangement is used when but one impression is to be made from a printing device. To bring about automatic control of the engagement of the notch 78 with the lug 75 I provide the following arrangement. An arm 105 is pivotally mounted on the bracket 24 at 106. This arm includes a reduced portion 107 through which the screw 108 is extended, said screw engaging .a' reduced portion 109 on the arm 80 at the end thereofopposite the pin 82. One end of the arm 105 extends through an opening 110 (Figs. 2 and 3) in the bracket 24 and is disposed below the pin 111 mounted at the upper end of the arm. 112 that is pivotally mounted at 113. .On the arm 112, below the pivotal mounting 113, is a pin 114. Extended through the discs 98, 99, and .100, are six pins 115 equidistantly and circumferentially spaced in the discs. As six pins are provided, the discs are notched in multiples of six and the discs have been described as having twelve, eighteen and twenty-four notches in theperiphery thereof. When the machine is arranged for consecutive operation, the pm 114 remains engaged with one of the pins 115. i A spring 116 extends between the bracket 24 and the arm 112 and acts on said arm to hold the pin 114 in engagement with a pin 115. When the pawl 88 is moved into alignment with, for example,

the disc 98 having twelve notches therein, and

the spring 116 pivots the arm 112 to cause the pin 111- to move downwardly. Downward movement of the pin 111 similarly pivots the engaged end of arm 10.5 and, therefore, the end of arm 1.05 bearing: the screw 1 08 moves: upwardly. This pivots the arm which, causes the. pin 82'. to move along the inclined portion of the pin 83- to disengage the notch 7.8 fromthe lug '75 and to thus disconnect the rocker 63. from. they rocker 66 which, as previously pointed out, disconnects the printing device feed. The screw 1118 is adjustable and, therefore,.the amount. of movement imparted to the arm 80 may be. easily varied. Upon the next. operation, of. the pawl. 88,. the. disc 98 will again be moved one-twelfth of a revolution. It has been pointed out that there are six of the pins 1.15 and that these pins are equidistantly and circumferentially spaced; therefore, when the first one-twelfth: of a revolution was imparted to the disc 98', the disc was rotated in an amount suflicient to. dispose the pin 114 midway betweenv two of the pins 115. Thus, when the latter one-twelfth. of: a revolution is. imparted to the disc, the succeeding pin 115 will be moved into engagement with the pin-114 and. this. will pivot the arm 112 upwardly. A spring 117 extends between the arms and 80 and holds the ends of these arms in engagement with each other. Therefore, when the pin 111 moves up wardly, the end of the arm 105 carrying'the screw 108 will move downwardly and the spring 117 will act to reposition the arm 80 in the position illustrated in Fig. 1 and thus the rocker 68. will be reconnected to the rocker 68 and the printing device feed will againfunction. Shouldthe pawl 88 be aligned with the disc 99 and the pawl then be operated, it will move over the shield 97 and will engage one of. the notches of the disc 99 and will impart to said disc one-eighteenth of a revolution. This will disengage one of the pins p from the pin 114, and, the printing device feed will be disconnected when downwardmovement of the pin 111 occurs. However, under this condition, the pin 114 will be-disposed one-third of'the distance between the pins-115 and thus upon the next operation of the pawl 88 the-disc 99 will again be moved one-eighteenth of a revolution and the succeeding pin 115 will not engage the pin 114 and, therefore, the printing device feed will again not operate. However, on the next. operation of the pawl 88 the disc 99 will again be moved oneeighteenth of a revolution and during this operation the succeeding pin 115 will'engage the pin 114 and, therefore, the printing device feed will again be placed in operation. It is therefore apparent'that when the pawl 88 is aligned with the disc 98 the printing devicefeed isinterrupted on alternate operations of the'machineand when the pawl is aligned with the disc 99 the. printing device feed is interrupted for two consecutive operations of the machine and is not reengaged until the third successive operation. Thus, since twenty-four notches'are provided in the disc 100, it is apparent that the disc will be rotated but one-twenty-fourth of a revolution on each operation of the pawl 88 therefore, when apin 115 is disengaged from the pin 114 the succeeding pin will not engage the pin 114 until the fourth. following operation of the pawl 88. vAs the pawl 88 is operated with the platen, it controls the opera-- rod 11.9; is connected to: the; bearing. portion; 90 and the other endv is mounted. in the. bifurcation in the lever 121 (Fig. 6). The. lever 1 21 is fixed on a, shaft 122; that is supported at the rear edge. of: the bed 16. A handle 123 is; connected tothe shaft; 122 and is movable into registration with suitable indices on: the upper surface of the bed. which indicate the setting, lock:- ing means. of approved. form being; provided to retain the. handle. in registration with, different ones of theindices. As best. illustratedin. Fig. 7, suitable spring washers 124 are. disposed between the discs 98, 99, and. 100, and these spring washersv exert sufficient tension onthe. discs to. prevent turningv thereof other than that. caused. by the pawl.- 88.,

At the time the. head H of theselector mechanism moves into the position illustrated in.Fig.. 2 whereat the fingers F are engaged with the printing. device in selector position,.thearm 27. is:moved into a. downward position and the triangularly shaped lug 29 rests on the edge 34 and as; has been, previously described, when the lug rests: on this edge, the arm 22 isso pivoted that the. notch 25 is disengaged from the lug 21 so that the platen arm is unlatched. As the platen moves downe wardly into printing position, the pawl 88. acts on the disc with which it is aligned, in event said pawl is aligned. with one of the discs, and moves the pin. 115 from engagement with the pin 114 whereupon the spring 116 pivots the army 112: in a clockwise direction as viewed inFi'g. 2. At the lower end of the arm 112 there is a shoulder 125 and on the arm. 27 there is a lug 126 having a flattened face. The. pin 115 will. disengage. the pin 114 at the time the arm 2'7 is. in. the position illustrated in Fig. 2', which, as previously stated, is a time at which the triangularly shaped lug 29 is. engaging the edge 34 and the fingers .F are engaging the printing device in selector position. When the arm 27 is in this. position the flat surface on the lug 126 is below the plane. of thehorizontal portion of the shoulder 125 and consequently, due to the influence of the spring 11.6, the shoulder will move above the flat surface on the lug 126 and these parts will be held. in. en.- gagement by the spring 127. Consequently the head H will be held in a. position whereat the fingers will remain in engagement-with the printing device. in selector position and thelug, 29 will remain in engagement with the edge 34. In a manner previously described, the feed of the printing devices will have been interrupted and consequently, when the-platen returns to: its upper oirnon-printing position, it may immediately start to descend into printing position to make an. impression from the printing device from which. an impression was previously made for this printing device will remain in printing position. If the device is arranged for making duplicate impressions, the. succeeding. pin 115 will, upon the second descent. of the: platen, engage. the pin 114, whereby the shoulder 125 will be disengaged from the lug. I26. Consequently, the parts. may function as determined by the selector mechanism. If the device is arranged for triplicate or quadruplicate impressions, the succeeding pin 115 will not yet engage the: pin 114 .and hence the shoulder 125' will remain in engagement with the lug 126 and the platen will make another operation so that at. least another impression will be madeirom the; printing device in printing posi' tion. It is therefore apparent. that the multiplicator forming the subject matter of -this invention not only arrangesgforirepetitious operation of the platen but also renders the selector inoperative until the last of the repetitious im-.

pressions is made by the platen.

It is manifest from the foregoing description that I have provided a multiplicator which may be easily set up so that consecutive, duplicate, triplicate, or quadruplicate impressions will be made from the printing devices. The set-up of the mnltiplicator is determined by a manually movable handle conveniently located in the bed of the machine. Further the multiplicator not only brings about interruption of the feed of the printing devices but likewise releases the platen latching arrangement so that it will not move into latching position until the desired number of impressions have been made. Moreover, the multiplicator renders the selector inoperative in a manner such that the selector again becomes operative and determines the operation of the machine as the last of the repetitious impressions is being made. The device is of simple and economical construction and is efiicient and positive in operation and moreover it embodies but. a few parts which may be arranged at a convenient location in the machine tothereby facilitate servicing thereof. t

In the foregoing description I have illustrated and described a selected embodiment of my invention but it is to he understood that this is capable of variation and modification and I there-' fore do not wish to be limited tothe precise details set forth but desire to avail myself of such changes and alterations as fall within the purview of the following claims:
