4 Claims. (Cl. 101?..269)

This invention relates to printing machines and,.particularly to printing machines for producing printed representations fromindividual printing devices. The present disclosure is a division of the application of Franklin E. Curtis, Serial No. 78,205 filed February 24, 1949, now Patent. No. 2,656,103, patented October- 20, 1953.

In printing machines of the aforesaid character, it is quite common to use roller platen structures whereby a resilient platen roller is moved across the paper so as topress the same intorprinting cooperationzwith the printing means of the printing devices, and an important object of the present invention is to-improve such roller platen structures. More specifically, it isan object of the present invention to afford a printing machine in which a roller platen structure attains its printing cooperation with the printing means of the printing devices simply through movement of the platen in a horizontal plane, and arelated object is to enable such a rollerplatenstructure to attainthe desired printing cooperation without the necessity for imparting upward or withdrawingmovements to the platen roller at the endof its printing operanon.

Other and further objects of the present invention will be apparent from the following description and claims andare illustrated in the accompanying drawings whieh,

For purposes of disclosure, the present invention is herein illustrated as embodied in a printing-machine 2110, Fig. 1, that is described. in detail. in the above identified application of Franklin E. Curtis. The printing ma chine 200 is adapted to handle individual sheets in the form of card checks which are identified as S in the afore said application and which are stacked in a magazine CM at one side. of the machine. These card checks S arefed one-by onefrom the magazine CM along a guide: way SG-1 tov a printing station 205 whereat a platen mechanism P-l cooperates with other elements in the machine at station. 205 and elsewhere to print variable data in the form of amounts on the cards. The cardsS are also punched at. station 205 with a code in the form of perforations.

The variable data andperforationsprinted:and punched respectively on the sheets S are each derived from a related code carried by printing devices identified as D in the aforesaid Curtis application, there being a sensing head SH, Fig. 2, in the machine which detects the coded information carried by the printing devices D and institutes transmission of the corresponding message tothe station 205. This type of printing device also carries data in the form of embossed names and addresses which are to be directly reproduced in the machine 200 as will be pointed out below.

The aforesaid printing devices D are supplied to the machine from a magazine M located adjacent one. side, thereof. Following the sensingof the printing devices D at the station SH, which occurs after they are fed from. the magazine M, the printing devices are next each ad-. vanced. along a suitable guideway to a printing station. 214 at which printed impressions are made directly therefrom on to a proof sheet such as the proof sheets shown,

in Figs. 5-7 of the above identified application. The

proof sheet having been supplied with data in the form.

of names and addresses from the devices D, the sheets.

S are next supplied with this same data from the printing: devices D at another printing station 210, Fig. 1, follow-I ing which the printing devices D and card checks S are each fed out of themachine and into respective supply h ppe and hep oq eet e o. a pa e and Pr e 218; Fig. 1, whege it is severed into individual lengths,

of; an endless web W at this stage of operation) by the action of a roller platen mechanism P-2 with which the.

present invention is particularly concerned. As shown in. 4 of. he ra n s e ala e m c an sm P-Z is a n ed rmq e e s t e wast ng tat n 4 r l e nes f mbassed, charaater a r ed. n. e pr n ing devices D. This plate mechanism is carried on a rigid printing frame 216, Fig. 3, that is arranged to extend upwardly near the rear edge of the machine and then to extend forwardly so as to be disposed over the printing stations 214 and 210.

In addition to the platen mechanism P-2, and the platen mechanism P-1 mentioned above in connection with station 205, the machine 200 embodies other platen mechanism P-3, Fig. 2, and P-4 (not shown). The platen P3 is of the stamper type, and is located at the station 210 forwardly of the station 214 in position to cooperate with other elements at station 210 to imprint the embossed data carried by the printing devices D on to the card checks S. The platen 13-4 is also generally of the stamper type and is disposed at station 214 in position to eifect printing of amount data on the proof sheet W, this latter data corresponding to that printed on the sheets S at the station 205. The platen mechanism P1, P3 and P-4 constitute no part of the present invention, description of such mechanism being made herein simply to relate the various stations in the machine to the type of printed impression and to the positions occupied by the principal elements of the machine itself. For details in this regard, as well as to the over-all details of the machine 200, attention is again directed to the above identified Curtis application.

The individual proof-sheets shown in Figs. 57 of the Curtis application are produced in a pager and proofer unit 218, Fig. l, which is supported on the printing frame 216 above and forwardly of the printing station 210, and the paper that is supplied thereto originates from rollers R, Fig. 1, located generally rearwardly in the machine 200. The webs of paper to be printed at the station 214 are threaded and guided through the machine and are arranged as a common endless strip W so that carbons may be made. This common web or strip W is guided upwardly through a diablo mechanism 219 at the front of the machine and into the printing station 214 where it is to be printed.

The web W is withdrawn from the rollers R by a pair of rollers 1309 and 1310, Fig. 17, and the Web then passes over a series of rollers and finally through a pair of guide plates 1327 and 1328 into printing position beneath the platen P2. Following the printing operation at the station 214-, the web is passed by another series of feed rollers into the proofer and pager 218.

The printing station 214 whereat the platen P-2 is located is defined by this platen and the cooperating anvil 734 above and on which the printing devices D are located one by one during the course of operation of the machine 200. The printing devices are fed into the printing station 214 in an advancing direction from the magazine M along the guideway that is defined by a pair of spaced apart guide tracks or rail members 701 and 702 between which and to which the anvil 734 is secured. This advancing movement of the printing devices is carried out in a step by step manner by the feed means described in detail in the aforesaid Curtis application, the feeding of the printing devices D, the advancing movement of the web W, and the action of the platen P-2 being timed relative one to another to etfect successively new impressions from the printing devices in spaced relation one after the other on the web W.

The platen P-2 is carried on the rigid printing frame 216 as hereinbefore pointed out, and the particular way in which this platen mechanism is mounted is illustrated in Figs. 3 to 14. Thus, the printing frame 216 is afforded by a pair of rigid and generally C-shaped side plates 825 and 826 that are mounted in position on the machine frame so that the upper arms of the plates 825 and 826 are disposed above the guideway for the sheets S while the lower arms of these plates are disposed beneath the table top T-1 of the machine.

In attaining this mounting arrangement of the plates 825 and 826, it should be pointed out that the machine frame comprises a plurality of uprights 827 extended upwardly from a lower base frame 828 of rectangular form, this base frame in turn being supported on bottom rails 829 that are arranged to engage the floor. The uprights 827 are connected along the rear side of the machine by a plurality of horizontal mounting bars 830, 831 and 832, while at the front of the machine the uprights are connected by a pair of horizontal bars 833 and 834.

At the rear or closed end of the C-shaped plates 825 and 826, these plates are arranged to be connected to the upper mounting bar 832, While at the forward end of the lower arm of each such C-shaped plate, a connection is effected with a longitudinal mounting bar 835 which extends parallel to the bar 834 and somewhat rearwardly thereof.

Between the upper arms of the plates 825 and 826, provision is made for supporting the platen P-2. There a pair of parallel mounting rails 843 and 844, Fig. 4, are extended between the upper arms of the C-shaped plates 825 and 826, and these mounting rails are secured in position to afford mounting space within which the roller platen P-2 may be mounted as hereinafter described.

The roller platen P-2 is illustrated in detail in Figs. 4 to 14, inclusive, and it will be evident in these views that the roller platen P-2 embodies a carriage C that is disposed between the rails 843 and 844, and is mounted for longitudinal reciprocation along a path that is transverse with respect to the printing device guideway 701-702 which is located so that the carriage passes over the position occupied by the anvil 734. In affording the desired support for the carriage C on the rails 843 and 844, these rails have horizontally projecting tracks afforded thereon by means of plates 846, Fig. 4, that are secured to the bottoms of the rails by screws 847. The arrangement is such that these plates extend toward each other so as to project beyond the adjacent surfaces of the supporting rails 843 and 844, and the projecting tracks that are thus afforded are arranged to be engaged by supporting and guiding roller means. Thus, near the center of the carriage C, front and rear rollers 848 are mounted so as to ride along the upper faces of the respective rails or tracks 846. The carriage C also has a pair of front rollers 849 and a pair of rear rollers 859 mounted thereon and arranged to engage the lower faces of the respective tracks 846, and the rear rollers 850 each have a somewhat larger guide disk 850G associated therewith so as to extend into a downwardly facing guide groove 846A formed longitudinally in the lower face of the rear guide rail 846. Thus, the carriage is guided along an accurately defined path over the printing station defined by the anvil 734.

The carriage C as herein shown is arranged to afford two positions at which platen rollers PR may be supported, but in most of the views from Figs. 4 to 14, only one such platen roller has been illustrated in the lefthand operating position in the machine, the other or right-hand mounting position having been provided for use in connection with two-column listing work when this is required. Thus, the carriage has a pair of downwardly projecting mounting plates 851 disposed near the front and rear edges thereof, and these mounting plates serve to support certain of the elements of the mechanism. These mounting plates are formed as elements of a bottom casting 852 that is secured to the lower face of the main carriage casting by means such as bolts 853, Fig. 7. In affording a mounting for a platen roller PR, adjustment in a vertical direction is provided in order that the printing pressure may be accurately determined, and in accomplishing this result, a pair of links 854 are extended generally horizontally to the left, Fig. 6, from aligned pivot points 855 and 856 afforded, respectively, in the lower corners of the mounting plates 851. These links 854 are extended to.

the left and are pivotally connected at their left-hand ing supported at their upper ends on a vertically adjustabl scrqss shaftBfiQ, ,Fig. 11. ,Adjustment of the cross s aft. is atta ned by meanslincll l ap of ius ingnu 6J1.. ha areoif r und .f rm d extend downwardly through the upper parts of .the, carriage C. vA retainingplate 861? engages reduced neck portions on the .nuts 861, and screws extend downwardly through the plate 861Pand into studs '8'6'1Sthat extend upwardly through the carriage casting so that this structure;holds the nuts 86'1 in fixed'longitudinal positions while .permitting rotative adjustment by engagement of the kerfed upper ends of. thenuts'861. 'The nuts 861 are internally screw threaded,,and-engage upwardly extended threaded studs formed, on members 862, Fig.1 1, that have apinned connection with the ,cross shaftf860 as shown at 860A. Thus, -by;operation. o,f the adjusting nuts 861, the cross shaft 860 maybe raised or lowered, and since the adjusting nutsfifil are disposed-near the front and rear ends, respectively, ofthe cross shaft'860, these nuts may also be used for the purpose-of leveling the platen structure. The -nu ts 861 are arranged for normal adjusting operation-'in-unisonby a knurled head-863 that is mounted for limited vertical movement in a non-rotative relation onastub shaft'863M 'fl-iat extends downwardly through the main carriage casting, Fig. 14. This is accomplished by apin and slot arrangement863Y, and a spring 863Z beneath the head 863 urges the head toward an upperrelationwith respect to the-shaft 863M. A spring plunger 86311 in the shaft 863M, Fig. 14, acts against a stud SGSX to :urge the -shaft-863M upwardly so that a gear 864M *tixed thereon is in the plane of and meshed with a :pa'irof idler gears 8646 that are carried on the lower ends of the studs -861S. The gear 864M also engages stationary pin 86,4P when :the gear is in its upper positiomthereby to :be locked against rotation. These idlengears 1 -8646 mesh with :gears ..-864H fixed on the nuts 8.61, and when the head1863 .is moved downwardly from its normal position to the end of the lost motion afforded :by the pin and slot.8.63Y,-the .gear 1864M is disengaged from .theloeking .pin 8641 .while still-remaining engaged with the idler :pinions. Whenrthis is done, the head-1.863 :Will actuate .theanuts .861 in unison :to .cause ordinary ia'diustment of the printing pressure. When a leveling operation1isto be :performed, the shaft 863M is depressed todisengage the gear 864M from the idlers, an the nuts 861 may hen be adjusted independently.

'{Ehcplaten roller PR is of :the positive gear driven typeso that theplaten roller rolls along the lines of emboss d cha cters on the :printing device ,D in timed relatienito th ,imcv mentof th pl ten carri g in such rolling action the desired cutoff action is attained by affording a resilient platen facingu865 .as shown in Fig. 7 of thedrawings. in accordance with the present invention, the platen carriage C is moved through a stroke in one direction to accomplish a 'particularprinc ing operatiomandat the end-of-the stroke, comes to rest in the position shown in Fig. *6, wherein the edges 865-1 and 865-2 are both spaced away from the tabletop of the machine. Then after advancing movements of the sheetstto be printed and-related elements, the next printing operation is-performed -by moving the carriage C in theoppos'i-te direction to e position wherein the platen roller BR occupies the position shown 'in dotted outline in Fig...6, ;inwhich-position the edges of the resilient platen facing are similarly spaced from the paper so that the desired sheet feeding operations on the web W may take place.

The gearing arrangement through which such positive rotative movements may be applied to the platen roller PR in the course of the aforesaid reciprocating movements of the carriage C are illustrated in Figs. 6 to 9 and 11 and 13. Thus, the rear vertical link 857 carries a platen mounting bearing structure which includes a pinion 867, and this pinion 867 is meshed with a pinion 868 that is carried by the link 854. The pivot pin 856, Fig. 13, carries a pinion 869 that meshes with the pinion T 68,. .1id'thi$, pinup 86 me he w t api oniavo ma is mountejd on a shaft3871 that extends from front to rear thr ugh the mountingplates 85.1. 'The pinion 870 'is fixed on theforwardend'of a sleeve872, and at its rear end thissleeve carries a gear,873. .The gear 873 is disposed so as '10 underlie and bemeshed with a rack 875, Fig. '9,that extends substantially parallel to the path of movement ofthe carriage C., The left hand end of the rack875gis pivoted at 876 'on a bracket 877 that extends downwardly from the rear face :of'themounting railf844, it being observed that in Fig. 9-this structure is shownin a reverse relationship. The sleeve 872 has a guiding bracket i877 frotatabl y associated therewith, and this bracket is extended upwardly "and bent around "the upper edge of the 'rack 875 as indicated at 877G. Thus, when the carriage C'is moved longitudinally, the guide-877 moveswith the carriage C and along the rack '875 :and assures that the rack 875 is maintained in mesh relationship with respect to the gear 873. 'With the arrangement-thatis thus afforded, the free end of the rack; 875 that is meshed-withthe-gear873 is able to followthe up and down adjusting movements of this gear 873 when the platen pressure is being'adjusted and, hence, the pressure adjustments areattained-without changing .the cutoff relationship of the platen face 685. The mounting, adjusting and-driving arrangements just-described are in effect duplicated at the right-hand end of the carriage C to afford another platen-roller position.

The carriage C is actuated through the desired reciprocating stroke by a pair of links 830 that are pivoted onpivots1881 *nearthe front and rearedges of the carriageC, and these lin'ks 880 are extended to the left and are respectively pivote'dat 882 to a pair of similar arms 883 that are extended in parallel relation from opposite ends of a mounting sleeve 884. The mounting sleeve 884 -is :fixed-on amounting shaft .885 that is extended horizontally through the mounting rails 843 and'844, and on the projecting rearend of the shaft 885, a bevel gear ,segment 886 is fixed. This bevel gear segment is meshed with a bevel gear segment 887 that is fixed on a horizontaleshaft 888 that is supported by. a bearing bracket889 :andiby a bearinginthe left-hand plate825. Just to tthe left of thep'late 825, an arm 890 is fixed on the shaft-888, :and *the upper end of an actuating link 595 is pivotallyvassociated-with the arm 890. Thus, when the'zlink 5 istmoved "in a downward direction the carriageiC is imoved=to the leftto .the position shown in Fig. 5, :while movement of the link 575 in an upward direction :actuates the carriage C to the right and into the position-shown in-Figs. 6 and 7.

It-wi-lliberecogniized from the above that movement of :the drive link 595 actuates the platen mechanism P-2, and :this .action of the1ink595 is controlled by a bell crank lever 593, -Fig. 16, which in turn is driven by a motor375, Fig. 3. 'Thus, there is a main drive shaft 380, Fig. 23, which extends through the machine 200 generally parallel to the horizontal mounting bars 830' 834, and this shaft iscontinuously rotated by a belt and pulley connection.316,'37.8 running from the shaft 380 to the motor v37S. As shown in Figs. 15 and 16, a pinion gear 5.63 .in mesh with a larger gear 564 driven by'it is carried atone end of the drive shaft 380. The gear 5.64vis loosely mounted on a'shaft 565 and constitutes the driven element :of a one-revolution clutch 570, Fig. 16, which, when coupled as described in the said Curtis application, imparts a driving movement to the driven element of the clutch 570 in the form of a pinion gear 586. The pinion 586 is meshed with a larger gear 588 which it drives on a shaft 589.

The gear 589 has a cam 590 fixed thereto so that the cam is rotated with gear 588 so long as the clutch 570 is engaged. The cam 590 is arranged to cooperate with a pair of cam followers 591 and 592 which are carried, respectively, on either end of the bell crank 593 which is mounted for rocking movement on a shaft 594.

The lower arm 593 of the bell crank is connected to the lower end of the drive link 595, and it will be readily seen that rotation of the cam 590 in cooperation with the followers 591 and 592 is effective to rock the bell crank 593 and reciprocate the drive link 595, reciprocable movement of the latter in turn accounting for reciprocable movements of the roller platen P-2 as above described.

From the foregoing it will be apparent that the present invention affords an improved and simplified roller platen structure, and in accordance with the present invention a roller platen structure is provided which attains its printing cooperation with the printing means of the printing devices simply through movement of the platen in a horizontal plane, thereby to attain the described printing cooperation without the necessity for imparting upward or withdrawing movements to the platen roller at the end of its printing operation. 1

In a printing machine, a reciprocable platen carriage at a printing station, means supporting and guiding said carriage for horizontal straight forward movement at the printing station during printing strokes, a platen roller mounted on said carriage on a rotative axis, means for adjusting vertically and levelling the axis of the platen roller, means to feed a sheet to be printed through the printing station and along a path that extends beneath said platen roller, said platen roller having an uninterrupted segmental resilient surface terminating in spaced apart edges that are substantially parallel to said axis, said roller being positioned in said carriage so that said spaced edges are in substantially a horizontal plane spaced above the path of such sheet when the carriage is at opposite ends of its stroke thereby enabling such sheet to be freely fed beneath the platen roller between strokes without engaging the platen roller, and means for reciprocating said carriage to move said carriage through printing strokes in opposite directions and causing said uninterrupted segmental portion of the platen roller to bear on and travel across such sheet, the last-named means including gearing on the carriage for rotating the platen, a pivotally mounted rack for driving the gearing upon reciprocation of the carriage and enabling adjustment of the platen roller to be easily accomplished, a rock shaft, and a drive arm connected to and between the rock shaft and carriage.

4. In a printing machine, a platen carriage, means supporting and guiding said carriage for horizontal movement during printing strokes in opposite directions, a platen roller mounted on said carriage on a rotative axis and for vertical adjustment to regulate the printing pressure, gearing mounted on said carriage for imparting controlled rotative movement to said platen roller during reciprocation of said carriage, drive means for the gearing including a rack disposed generally parallel to the path of movement of said carriage and pivoted on a fixed pivot at one end to enable said rack to pivot as required during said adjustment, said platen roller having a segmental resilient surface terminating in spaced cut-off edges parallel to said axis and spaced substantially from each other, said platen roller being so related to said gearing that said spaced edges are faced downwardly and substantially in the same plane when the carriage is at opposite ends of its stroke, and drive means including a rock shaft under control of a one-revolution clutch operable in successive cycles of the machine to move said carriage through printing strokes in opposite directions.
