14 Claims. (Cl. 101-91) This invention relates to printing machines and more particularly to a novel arrangement of printing machine which is operable to deposit or print data representing means at selected points on a record member such as a card, check or other document, for indicating data on such documents. Such indicating data or code can then be used, among other purposes, to verify the basic format of the printed document and/or to automatically process the document, using for instance conventional record controlled apparatus. The data representing means may either be of the visible kind or of the invisible kind, or a combination of both, and may be composed of any material capable of being sensed by suitable processing personnel or equipment.

The printing machine embodying the invention is particularly useful in printing indicating data in codified form on checks or the like, in which the basic format of the check has been previously printed in the conventional manner. In addition, in the latter use, the data representing means is preferably comprised of material of the kind essentially invisible to the naked eye, but which becomes active or visible when subjected to the proper type of sensing medium, such as a predetermined wave length of radiation. It will be apparent that such indicating data on documents such as checks, would not only provide means for authenticating portions of the infor mation in the printed format of the check, but also if suitably arranged, may be used in combination with con ventional sensing apparatus to automatically reproduce such data, translate the latter, or otherwise handle or process the check or document itself.

The present invention provides a printing machine unit for printing indicating data and/or a code on checks or the like and wherein such data may be effectively and eificiently printed at minimum cost. In accordance with the invention, the latter described printing machine unit may comprise an inking mechanism including a master inking cylinder for supplying ink for printing, an imprinting cylinder having a plurality of code impression segments mounted therein by means of a novel clamping arrangement, and adapted to imprint data representing means in a predetermined pattern or code, and an impression cylinder adapted to coact with the imprinting cylinder to transfer the ink, data representing material from the code segments to a worksheet, such as a check, passed between the bite of the imprinting and impression cylinders. The printing machine unit of the invention is particularly adapted for use in series with a conventional offset printing machine unit, which prints in conventional visible ink, the basic format of the worksheet or check, including such information as name of the drawee bank, the name of the drawer, etc., after which the check is passed through the printing machine unit of the invention, wherein the data representing means is printed in codified form on the check, with relatively invisible ink. The check or worksheet may then be passed through other units in series with the latter described units for performing other operations on the worksheet, such as perforating the check body or punching the latter in a manner well known to those ski.led in the art.

The printing unit of the invention thereby provides an arrangement that can be conveniently used in combina- .on with conventional printing or other operational machines, thereby providing a code printing mechanism Without the necessity of altering or otherwise redesigning existing printing equipment.

Accordingly the primary object of the invention is to provide a printing machine unit which can be effectively and efficiently used to imprint data representing means in code or other forms on a document, such as a check in which the format or body of the document or check has been previously printed in the conventional manner.

Another object of the invention is to provide a printing machine unit of the aforementioned type and wherein such data representing means when imprinted on the worksheet or document is" comparatively invisible to the naked eye, but which becomes active or visible when subjected to the proper actuating media such as a predetermined type of radiation.

A further object of the invention is to provide a printing machine unit which will effectively and efficiently imprint data representing means in codified form or otherwise, on a previously printed worksheet, such as a check, and wherein such unit may be expeditiously used in series with other units which perform, in a systematic manner, conventional working operations on the associated worksheet or check, to provide a continuous automatic operation and without the necessity of altering or redesigning such conventional units.

A more specific object of the invention is to provide a code printing machine unit comprising a master inking cylinder, a code imprinting cylinder having detachable code segments mounted therein by means of an operable latch or clamping mechanism, and an impression cylinder coacting with the code cylinder to transfer the ink, data representing material to the worksheet, when the latter is passed between the bite of the code and impression cylinders.

Another object of the invention is to provide a printing machineunit having a printing cylinder which comprises a plurality of movable or adjustable printing segments or slugs mounted therein for imprinting data representing means in codified form on a document or other worksheet, such as a check or the like, and wherein a novel clamping mechanism is provided on the printing cylinder for clamping or locking the printing surfaces of the printing slugs in a predetermined pattern or systematic arrangement by means of a Wedge bar coacting in wedging engagement with the printing slugs, to move the latter into tight, non-movable abutment against a shaft extending through the axis of rotation of the printing cylinder, but wherein the clamping mechanism may be quickly and easily moved to unlocking or inoperative position whereby the pattern arrangement of the printing slugs may be quickly and efficiently changed to conform to changing data on the format of subsequently fed worksheets.

Other features and advantages of the invention will be apparent from the following description taken in conated latching mechanism for clamping the code imprinting segments or slugs to the cylinder proper, a number of the printing slugs having been removed to better illustrate the invention;

'Fig. 11 is a vertical sectional view taken generally along 1111 of Fig. 10;

Fig. '12 illustrates a worksheet or check on which code markings (shown in phantom lines as Xd squares) have been printed in selected groupings or areas, by the aPParatus of the invention, together with an explanation of what such coded areas may represent.

Referring to the drawings, the printing machine comprises a pair of generally vertically extending side frame members it}, spaced apart by suitable cross frame mem hers (not shown). A supplementary frame 12 is pivoted to the main side frame 10 as at 14, and carries an inking system 16 thereon. Inking system 16 may be of any conventional type, such as is shown and described in the US. Patent No. 1,968,849, issued August 7, 1934, to Lawrence H. Morse, or US. Patent No. 2,065,535, issued December 29, 1936, to the same inventor. Accordingly the inking system will not be described herein in detail.

Supplementary frame 12 also carries a rotatable shaft 18 on which is mounted a master inking cylinder 20 which coacts with the inking train rollers of inking system 16 to furnish ink for the printing operation. Cylinder .20 has a rubberized blanket or surface so arranged as to transfer the ink from the inking train of system 16 to the imprinting segments or slugs mounted on the printing or code cylinder 22 in the optimum manner. In this connection the rubber blanket or surface of cylinder 20 may be so cut as to supply ink only to the areas oi imprinting on printing cylinder 22. The ink as aforedescribed is preferably of the type that is substantially invisible to the naked eye, but which becomes visible to selected processing personnel or equipment after being subjected to the proper actuating medium. An example of a suitable ink for the instant purposes would be one containing fluoroescent materials which would be substantially invisible under ordinary light, but which would glow and become visible when subjected to a different wave length of light, as for instance ultraviolet light.

Printing 'or code cylinder 22 is rotatably journaled on side frame 10 by means of cross shaft 24. Also rotatably carried on the side frames and below code cylinder 22, is an impression or platen cylinder 26, mounted on shaft 28. Suitable adjustments may be provided to align the axes of the above-mentioned cylinders with respect to one another, to permit regulation or adjustment of the distances therebetween, in a manner well known to those skilled in the art;

In the embodiment .of the invention shown, the printing mechanism is driven by an electric motor 39 mounted in the base cabinet 32 and drivingly connected to the impression cylinder 26 by driving elements, such as belt 34. The master inking cylinder 20, the printing or code cylinder 22, and the impression cylinder 26 are'provided with interengaging gearing 36 so that each cylinder will be driven in synchronism with the other.

The impression cylinder 26 is preferably equipped with suitable worksheet receiving or clamping mechanism to insure passage of the worksheet between the bite of the impression and printing cylinders. Likewise, a suitable worksheet ejector or stripping mechanism may be provided to insure discharge of the worksheet from the bite of such cylinders after the worksheet has passed therebetween. Suitable mechanism for such purposes are illustrated and described in detail in U.-S. Patent No. 1,968,849 heretofore mentioned. 7

At the proper time in the cycle of revolution of the impression cylinder 26, and in accordance with suitable timing devices (not shown), the worksheet, such as a sheet of checks on which the formats of the checks have been previously printed in the conventional manner, is fed on work table 38 into the bite of the impression and printing cylinders. The aforementioned sheet receiving mechanism on impression cylinder 26 clamps the leading edge of the worksheet, and the latter is progressed between the cylinders 22 and 26, at which time the data representing means or code is imprinted on the worksh he or shee s may be either .f manua y or by a omatic me an s such as a ser es o mo t p into th it o t impre si n an p n y ders. After being imprinted with the code, the workhee is s ripped fr m t e impre sion cy n r. y the aforementioned ejector or stripper mechanism and is received in tray portion 4i? of the machine. It will be understood, of course, that if the printing unit illustrated is placed in series with other worksheet processing units in the manner discussed in the initial portion of this specification, the worksheet is preferably moved automatically to the bite of cylinders 24 and 26, the code is imprinted thereon, and then the worksheet is automatically carried to the next operating apparatus in the series, such as by means of moving tapes, for further processing.

The printing or code cylinder 22, comprises a generally hollow, cylindrical body portion .42 secured to shaft 24, a plurality of code imprinting segments or slugs 76 adjustablyor movably mounted on shaft 24 in body portion 42, a series of spring loaded plnngers or resilient detents 80 or main a ning t e Printi g sl g 76 in asse d d t n i e yl nder, a c amp ng mechanism 55 moun d o cylinde shaft 24 and including a wedsebar 69 adapted for Wcdging ,coaction with the printing slugs 76 to lock the latter in'a predetermined pattern arrangement on the cylinder, and a series of spaced window plates 96 removably mounted on the body portion 42 for use in visually indexing the printing slugs 76 'into said predetermined pattern arrangement when the clamping mechanism 55 is in unlocked or inoperative position. The generally hollow, cylindrical-like body portion 42 has end walls 44 which carry the aforementioned shaft member 24. Spaced transversely along shaft 24 intermediate end walls 44 are a series of tapped openings 46 into which abutment projections such as bolt or screw members 48 are threaded. Lock nuts 50 maintain members 43 in a predetermined axial position with respect to the associated tapped receiving opening 46. Each of elements comprises a head portion 52 which is adapted for engagement with locking or supplementary shaft member 54 of the aforementioned clamping mechanism as.

Clamping mechanism 55, in the embodiment of the invention illustrated, broadly comprises the above-mew tioned shaft 54, housing or bearing blocks 56 having projecting means 60 for mounting the clamping mechanism 55 on cylinder shaft 24 for generally radial movement with respect to the shaft 24, arm elements 64, which support the aforementioned wedge bar 69, and a handle or lever element 100 for manual rotation of supplementary shaft 54 with respect to the housing blocks 56.

Shaft 54, which is generally cylindrical in vertical cross section, has a series of flats or planar sections or surfaces 54a spaced transversely therealong in generally aligned relationship with the axes of the aforementioned tapped openings 46 in the cylinder or main shaft 24. These planar sections 54a are adapted for unlocking the clamping. mechanism as will hereinafter be discussed in more detail. Shaft 54 is rotatably mounted in a series of the aforementioned transversely spaced housing or hearing blocks 56. Blocks 56 are disposed in generally confronting relationship to cylindrical like collar portions 58 on cylinder shaft 54. A boss or cylindrical lug 60 extends inwardly toward the axis of shaft 24 from each of housing blocks 56 and is received in telescoping relationship in a complementary confronting recess or opening 62 in each of the collar portions 58.

An arm 64 is mounted on each of the housing blocks 56 and projects therefrom toward the outer periphery of cylinder 22. Arms 64 are attached to blocks 56 by any suitable means, and in the embodiment of the invention shown such means comprises a stud 66 (Fig. 4) projecting outwardly from block 56 into a complementary opening in the inner end of arm 64, and a threaded member, such as a bolt or screw 66:: threadedly engaged in tapped hole 67 in the block member 56.

The outer or free ends of arms 64 are connected to the aforementioned, transversely extending wedge bar member 69, as by means of fastening elements 72. Bar 69 has a wedge surface 69a thereon, which faces toward the cylinder shaft 24 and the supplementary shaft 54,

substantially in line with the axes of these shafts (Fig. 4). Wedge bar 69 is adapted to engage a serrated or notched portion 74 on each of code or data printing segments 76, and clamp the latter in the printing cylinder 22.

Printing segments 76 are of generally fiat, segmental like or quadrantal configuration (Figs. 8 and 9), having a collar portion 76a which is adapted for engagement with cylinder shaft 24, a segmental code printing and indexing portion 76b, and the aforementioned serrated or notched abutment portion 74. Printing and indexing portion 76b extends radially outwardly further than does toothed portion 74, and comprises at opposite extremities thereof, outwardly projecting lug portions 78 and 79. Lug portion 78 has a code or data printing surface 78a thereon which extends through a window or opening 77 cut into the periphery of the cylinder wall. Surface 73a, in the embodiment of the invention illustrated, would print a generally square mark on the worksheet or document, but it will be understood of course that the printing surface of slugs 76 could be arranged to imprint any configuration of identifying mark on the associated worksheet. Lug portion 79 has a recess 79a therein which is adapted to receive a pointed tool or like instrument for manually rotating or moving the segments 76 about shaft 234 to change the pattern arrangement of the printing surfaces 78a of printing slugs 76 to conform to changes in the printed data on the format of the worksheet (i.e. in the case of checks, changesin bank branch numbers, account numbers, commands, etc., see Fig. 12). Lug portion 73 extends radially outwardly from the axis of cylinder shaft 24 a greater distance than does lug 79, thereby insuring that only the printing surface 78a on lug 78 will engage the worksheet during printing operations.

' Intermediate the lug portions 78 and 79 are provided identifying media 81, such as the Arabic numbers illustrated in Fig. 9, which are for use in properly positioning or indexing the printing surfaces 78a of the code segments into a predetermined pattern, for printing data representing means in the aforediscussed codified form on a worksheet.

A plurality of spring loaded studs or plungers 80 are mounted on cylinder wall 88 of cylinder 22 (Figs. 3 and 4) and extend inwardly toward the axis of the cylinder to enage the notched portions 74 of code segments 76, to retain the latter in assembled condition with shaft 24 of the cylinder, when the clamping mechanism is moved to unlocked position. Studs 80 comprise a spring loaded plunger member 80a (Fig. 7) disposed in a peripherally threaded body portion 80b which is threaded into trapped openings in the cylinder wall as best illustrated in Figs. 4 and 5. Lock nuts Stlc (Figs. 4 and 5) maintain studs 89 in a predetermined inwardly extending position with respect to wall portion 88. It will be seen that studs Sil maintain the code segments 76 in assembled position in cylinder 22 and releasably hold the printing segments during indexing of the latter to change the pattern arrangement of printing surfaces 78a on the code segments in accordance with changes in the printed information on the format of the worksheet, while clamping mechanism is adapted to positively lock the code segments 76 in a predetermined pattern arrangement to insure against inadvertent movement of the code segments about shaft 24 during the printing operations and resultant rotation of cylinder 22.

Studs are staggered in two rows (see Fig. 3) along the cylinder wall 88 of the cylinder, in the interests of adequate space for the size of stud used, and for maintaining the strength of wall 88 in the vicinity of these studs. The studs 80 are so disposed on wall portion 83 that the axes of the studs lie in planes which pass substantially through the axis of cylinder shaft 24.

In the embodiment of the invention shown, eleven of the code segments 76 are adapted to be mounted in each of the window openings 77 in the cylinder walls (Fig, 3) and thus three documents, such as three checks, in the form of a single Worksheet can be code imprinted at the same time, with each printing revolution of the cylinder. It will be understood of course that the invention is not limited to imprinting code on only three documents but may be used to imprint a single or any number of documents, the only limitation being the transverse width of the cylinder 22 and associated number of printing slugs 76.

Plate-like code segments or slugs 82 (Figs. 4 and 10), commonly known as electros, are also mounted on the periphery of cylinder 22, generally adjacent openings 77 therein. Each of slugs 82 has a plurality of printing surfaces 83 thereon and are adapted to imprint generally permanent information in code form on the worksheet. In the case of printing checks, such permanent information might include such data as' the bank identification, the city, the State, the Federal Reserve District, etc. Segments 82 are mounted in assembled position on cylinder 22 by means of spring loaded locking plates 84, in com bination with shoulder plates 56 (Fig. 4), suitably attached to an end of wall portion 88 of the cylinder, as by means of screw members 89. Locking plate 84, on one end thereof, has a flange portion 84a which is received in an opening in wall 88 of the cylinder'22, and on the other end thereof has a beveled surface 84b (Fig. 11) adapted for holding engagement with a complementary beveled surface on the confronting end of code segment 82, to hold the latter in an assembled condition on the cylinder 22. Locking plate 84 is spring loaded, as aforesaid, by spring 90 disposed between the inner surface of cylinder wall portion 88 and an abutment 92 (Fig. 4 on the inner end of stud 93 about which spring 90 is coiled. A notched or recessed portion 93a is provided on one edge of each of locking plates 84 and in superimposed relationship to an opening in wall 88 ofthe cylinder to provide means for inserting a tool, such as a hook, for readily moving locking plate 84 outwardly against the resistance to compression of the springs 90, and thereby permit release of code printing slug 82/. The confronting edge of printing slug 82' is also provided with a notched portion 95 complementary to notched portion 93a in the locking plate 8 to aid in the release of slugs 82. Since the data representing code printed by segments or siugs 82 is of a permanent, generally unchanging nature, these segments can be used and then be filed away for future use .in printing a batch of work sheets, such as checks, requiring the identical information thereon.

Extending across window openings 77 in the code cylinder 22, and attached to the cylinder walls are indexing plates 96 (Figs. 2 and 4), which have a series of transversely spaced windows or openings 96a therein, for use in visually setting or indexing the code segments 76 in a predetermined pattern, in accordance with the Arabic figures 81, or other identifying media, stamped or otherwise marked on code segments 76. Indexing plates 96, in combination with the aforementioned shoulderplates 86 (Fig. 4), limit the extent of permissible pivotable movement of code segment 76 about cylinder shaft 24. An opening 93 (Figs. 3 and 4) is provided in the cylinder wall on the side generally opposite to openings 77 therein, to permit easy access to the interior of the cylinder for locking and unlocking the clamping mechanism 55.

Operation of the mechanism to change the pattern of the code imprinting segments 76 is as follows: As best shown in Fig. 4, the handle or lever 160 projects from locking or auxiliary shaft 54 and in the position illustrated in the latter figure is in locking position. In this position the head 52 of threaded elements 48 engages in abutting, holding relationship with the generally arcuate, peripheral portions of shaft 54, thereby pulling or moving the wedge bar 69, into wedging coaction with the notched portion 74 of each of the code segments 76. The code segments 76 are thus held or locked against relative rotational movement with respect to the cylinder shaft 24. Worksheets are passed between the bite of printing and impression cylinders 22 and 26, whereupon the code printing surface 78a on codesegments 76 print, in a predetermined pattern and preferably in substantially invisible ink, the desired data on the format of the printed worksheet. The worksheet is then stripped from the impression cylinder and is deposited in tray 40 on the printing unit, or is progressed to other operational machines for further processing. The printing cylinder 22- may be pro vided with hearing rings 102 (Figs. 2 and 3), disposed intermediate the code printingareas of the cylinder, which will aid in carrying the worksheets through the printing position. Since the code printing cylinder prints from metal type, it will be preferable to provide a resilient or rubberized. surface on, the impression cylinder to oppose the metal code segments on the printing cylinder, to thereby insure better transference of the ink from the printing segments to the worksheets, Without injury to the printing surfaces 78a and 83 on the code printing segments 7-5 and 82.

When it is desired to change the code pattern being printed by the printing surfaces 78a on code segments 76', the handle 100 of clamping mechanism 55 is moved to the position illustrated in Fig. 5 of the drawings, thereby rotating the locking or supplementary shaft 54 and presenting the flat or planar surfaces 54a on the shaft in confronting relationship to head portions 52 of elements 48. The latter position of the parts permits the supplementary shaft to move radially inwardly toward cylinder shaft 24 thus releasing the tension onarm elements 64 and permitting the wedged bar 69 to be released from wedging coaction with the notched portions 74' of the code segments 76 as shown in Fig. 5. The latter segments can then be pivoted with respect to shaft 24 to set a new or different code pattern using the aforementioned windows 96a in indexing plates 96' to align the positioning indicating media 81 on the code segments with the respective window in plates 96 in accordance with a predetermined plan. The latter can be most conveniently and efliciently accomplished by inserting a pointed tool or instrument, as aforesaid, in the recess 79a in each of lugs 79 on code segment 76, and moving the desired one of the position indicating media 81 into underlying rel tionship with the corresponding window 96a in the indexing plate 96. Spring loaded studs permit such movement or rotation of the code segments 76, while holding the segments in assembled condition with the cylinder. It will be apparent that without studs 80, the segments might fall away from assembled coaction with the cylinder shaft 24 and jam in the cylinder when the clamping mechanism 55 is in unlocked position.

After the code segments 76 are reset into the desired pattern and in the manner described above, the handle or lever 19%) is-moved back to the position illustrated in Fig. 4 of the drawings, thereby rotating shaft 54 and moving the arcuate portions of the shaft into abutting relationship with the head portions 52 of bolt elements 48, whereby the shaft 54 and associated bearing blocks 56 are moved radially away from shaft 24 and arms 64 on the clamping mechanism are tensioned to thus pull or urge wedge bar 69 into wedging coaction with the notched or toothed portions 74 of segments 76, to lock the code printing surfaces 78a of the segments in a predetermined pattern arrangement. Movement of lever to locking position is limited by engagement with the cylinder shaft as. It will be seen that projections or studs 60 on each of the housing or bearing blocks 56 maintain the clamping mechanism in assembled condition with the cylinder, by extending sufficiently forwardly into openings 62 in collar portions 53 on cylinder shaft 54, to prevent withdrawal thereof from openings 62, even when locking shaft 54 is in unlocking position.

The printing segments 76 may be easily inserted into assembled condition with the cylinder, or removed therefrom, by merely unlocking the clamping mechanism 55 in the manner aforedescribed, removing the indexing plates 96 and drawing the segments through windows 77 or inserting the segments into windows 77 as the case may be, against the resistance to compression of spring loaded studs 86. The latter represents an important feature of the invention in that the segments 76 may be easily and efficiently changed or replaced with minimum effort and by relatively unskilled labor.

Code segments 83 which imprint data representing means of a generally permanent nature may be easily changed by grasping locking plates 84 through notched portion 93a thereof and lifting up on the plate, to thereby permit removal of code elements 82 from engagement with shoulder plates 86 and the beveled end 84b. of locking plate 84.

From the foregoing description and accompanying drawings it will be seen that the invention provides a print ing machine unit which can effectively and efficiently print data representing means in. codified. form on a worksheet or document and at a minimum cost. Such. unit, includes tam.)-

9 e means whereby the pattern of the code may be easily and quicklychanged to correspond to changing printed data on the format of the documents. Moreover, the printing unit of the invention provides an arrangement, whereby data representing means of a generally permanent nature can be printed on the document and in coded form together with the printing of the changeable data, and wherein novel clamping arrangements or mechanisms are provided to maintain the printing elements of the apparatus in locked or operative condition, but which can be easily moved to unlocked or inoperative position, to permit changing of the pattern of the code imprinting means.

The terms and expressions which have been employed are used as terms of description and not of limitation and there is no intention in the use of such terms and expressions of excluding any equivalents of the features shown and described or prti:ns thereof but it is recognized that various modifications are possible within the scope of the invention claimed.
