Application filed July 1. 1912. Serial No. 706,975.

- Be it known that I, ALBERT KRAUTH, a citizen or" the ll'nited States, residing at Hamilton, in the county of Butler and State of Ohio. have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

My invention relates to improvements in printing presses. with the press of a type primarily adapted for printing autographic register strips of paper in which each signature is numerically indicated and registered and accurately spaced to insure satisfactory use when a web is mounted within an autographic register and to aline with a series of sheets of duplicate subject-matter. Therefore. in this respect, my press comprises embodiments peculiar to the character of the usage of the printed matter. The press is provided with perforating and numbering mechanisms for for perforating the same to serve as alining means in the usage of the printed matter when fed in autographic registers'and as the original web is of an area to simultaneously print an original-signature and record copies thereof. the web may be severed into continuous strips dividing the various units. It is obvious. however, that the. press contains many features adapted for printing presses in general and while the drawings show the press designed for a special use it is readily apparent that the press and features thereof are not limited to such particular use.

One of the objects of my invention. is to provide a series of printing mechanisms, correlatively arranged to print upon both sides of the web of paper; primarily on one side and subsequently on the reverse side during the feed of 'the paper through the machine with the printing in different colors or otherwise as desired.

Another object of my invention relates to means for adjusting the platen cylinders relative to the printing cylinders to regulate the density of the impression and the essential characteristics reside in providing circumferential angular bearing plates upon the ...encls of the platen and printing cylinders with the angle of one bearing relatively opposed to that of its companion bearing,

whereby the lateral adjustmentof a platen cylinder enables it to be moved to or from its companion printing cylinder and producing a micrometer adjustment in a true plane over the entire circumferential area of the cylinder. This is especially advantageous in this type or" machine where an electro-type printing plate of circular form is used, as it overcomes all blocking diiiiculties heretofore resorted to for properly alining the impresslon surface of the printing plate relatively with the platen cylinder.

The features of my invention are more fully set forth in the description of the accompanying drawings. forming a part of this specification, in which Figure 1 is a side elevation of my improved printing press illustrating what may be termed the power side of the machine. containing the transmission to the various cylinders and ink distributing rolls. Fig. 2 is a detailed elevation of the paper tension device mounted at one end of the press. Fig. 3 is a side elevation of the press opposite from that of Fig. 1. Fig. 4 is an enlarged detailed section through the punch ing mechanism taken on line m, m, Fig. 3. Fig. 5 is an elevation of one end of the punching mechanism taken on line 5;, .r, Fig.

1. Fig. 6 is an enlarged detailed section through the punching members at their point of registration. Fig. 7 is a section on line v, r, Fig. =1. Fig. "8 is an enlarged side elevation of two of the printing rolls illustrating more clearly the hand levers for adjusting the printing and platen rolls or cylinders relatively to each other and the means for moving the printing cylinder out of contact with the platen cylinder. Fig. 9 is a section on line w, '20, Fig. 8. Fig. 10 is a top plan view of the numbering mechanism taken on line 2, 2, Fig. 1. Fig. 11 is a section on line y, y, Fig. 10. Fig. 12 is an enlarged detailed plan view of the numbering disks. Fig. 13 is a section on line u, u, Fig. 12. Fig. 14 is a side elevation of a portion of the ink reservoir. Fig. 15 is a section on line 12.. n, Fig. 14. Fig. 16 is a diagrammatic printing plate, whilecylinder is the platen cylinder, its periphery provided with the usual form of tippet to present a yieldingsurface common to all printing presses. A

represents the ink distributing mechanism for conveying ink. from the ink reservoir through the ink spreading rollers to the ink distributing roll engaging the impression surface of the printing cylinder 4. As the paper advances, it passes between the cylinders 6, 7, in this instance arranged above the first set of printing cylinders with the cylinder 6 comprising the printing cylinder, while cylinder 7 comprises the platen cylinder and is preferably arranged above and parallel to the platen cylinder 5. 'Thus the first set of. printing rolls or cylinders print on one side of thepa-per, while the secondset will print on the reverse side. The second set of printing cylinders may print in a different color from that of the first set as jects in the use of the printed matter. The

machine receiving the printed webs, which are usually in the nature of sales sheets or strips, maintains the rolls or webs of paper in a condition to be fed through the register and over manifolding sheets for making record copies of an original'transcript.

The number of manifold copies being optional 1 to meet the requirements of a particular user. With this third set of printing cylinders the original transcript is usually printed with the numeral 1 in a different colored ink than the main printed matter and directly over the same with the record or manifold transcript printed witha number designating its character. 8 rep-resents the printing cylinder, and 9 the platen cylinder of the third set of rolls and C the ink distributing mechanism for distributing ink to the impression surface of cylinder 8.

From the third set of printing cylinders the paper is fed between the numbering mechanism for consecutively numbering each transcript or signature with the means for consecutively adjusting the numbering disks or tumblers arranged to be automatically thrown out of commission after a predetermined number of impressions has been made to 7 permit a given number of signatures to be fed through the numbering mechanism to receive duplicate members, in-

dicating a division between two lengths of on a receiving roll from whence it is fed.

through. severing mechanism for dividing the various transcripts and arranging each into the register sizeof web.

With my improvements in printing presses the capacity is very materially increased and'the various elements conveniently adjusted, very materially reducing .the time in which the machine is out of '-commission for changing forms or regulating the density of the impression as the thickness of the tippet on the platen or cylinder' can be changed without removing the ,web of paper or without disturbing the correlative alinement of the printing cylinder with the-platen cylinder. The printing cylinder is jou'rnaled in eccentric bearings rotatively mounted with means for rotating the eccentrics to swing the printing cylinder to and from the platen cylinder. The platen cylinder at each end thereof is provided with an inclined angular flange adapted to engage with oppositely inclined flange similarly disposed at each end of the printing cylinder to define. the limit of the correlative adjustment of the two cylinders toward each other and thereby controlling the density of the impression. The adjustment is made by moving the platen cylinder axially "to change the points of engagement of the inclined surfaces of the annular flanges of said rolls. Thisenables convenient renewal of the tippet surfaceby increasing or. decreasing thethickness thereof which must be renewed assoon as it shows sign of wear and which renewal is more repetitious in highly 'speeded machines than otherwise.

Therefore, it can be readily seen that to maintain "a high capacity for printing presses the construction must be such as to reduce to a minimum the time per da s run and time out of commission for ad usting,

reloading or resetting for a change of run.

15 represents the base of the machine upon cf printing mechanism.

though the width may be of various area. 17 represents the main driving pulley mounted upon the shaft 18, suitably journaled within bearings formed in the side frames 16, with the driving pulley arranged adjacent to a loose pulley, (not shown) on shaft 18, for throwing the drive into and out of commission by shifting the belt from the driving pulley 11' fixed on the shaft upon the loose pulley or the reverse as desired.

The mechanism for shifting the belt, is, for.

pertinent as component parts of the machine as a whole does not forma part of this invention and therefore specific description and illustration thereof is hereby omitted.

Transmission.-As .the various sets of printing instru'mentalities are driven by gearing in train with the main driving shafts 18, I will first describe such gearing leading to the various divisions.

20 represents a pinion fixed on the shaft 18 in mesh with a gear 21, said gear being fixed to a shaft journaled within bearings formed in the side frames 16. 22- represents a gear in mesh with gear 21 and with a gear :21 which latter gear is in mesh with a gear 23. Gears 2:2, 23 and 21, forming the members of a train of gearing for driving the rewinding roll of the web atthe rear or right hand side of the machine, as illustrated in Fig. 1. The function of the re-- winding rolls and their operation to be hereafter more fully described.

25 r presents a gear in mesh with gear 21 and with a gear 26., The gear 26 is in mesh with a gear 2? for imparting motion or rotaticn to the numbering mechanism, the

said gear 26 is also in mcshwith. a gear 28 and the latter in mesh with gears 29 and 30, gear 29 conveying motion to the third set of printing cylinders and ink distributing mechanism. while gear 30 conveys motion to a gear 31 with the latter in mesh with gear 32, imparting motion to the second set The gear 31 is keyed to the shaft of the impression cylinder 7 from which motion is conveyed to the shaft 105 of the cylinder 5.'through intermediate gears 116 and 117 secured to the cylinders T and 5 respectively, (seevFig. 9),

the pitch diameter of the gears 116 and 117 is greater than that of the gears 31 and 33, thereby relieving the teeth gears 31 and 33 of driving contact with each other. This arrangement permits the spacing of the cylinders T and 5 with their surfaces out of 'contact'with each othe and at the same time prevents backlash or free play that would be present if the drive was direct from gear 31 to gear 33, said gears having their pitch lines separated on account of the cylinder spacing. The gear 33 is in mesh with a gear 31 conveying motion to the first set of printing mechanism,'while gear 35 is in mesh with a gear 36. Gear 36 is in mesh with a gear 37 conveying motion to the perforating mechanism. Thus it will be seen that a single source of poweris utilized for transmitting motion to the various divisions providing a positive drive free from slippage or lost motion and by constructing the intermeshing gears of different kinds of metal,

as for instance, the one of bronze and second steel, the machine runs practically noiseless, at the same time increasing its life. But as a positive drive is an important desideratum to the successfuhoperation of. this type of machine, I have found the arrangement herein illustrated as the nest satisfactory and practical. The supply web of paper is rotatively mounted with provision made for applying tension thereto to prevent unfolding of the web greater than its feed and maintaining the web taut at all times in its travel through the press. Means are also provided forlaterally adjusting the web to readily position a new roll with the function instrumentalities of ti e press. The mechanism provided is illustrated in Figs. 1 and 2.

38, 39, yepresentbrackets extending from the main frames 16, providing a bearing for the spindle 40, with the bearings of notched form, providing an opening for the convenient and ready removal of the spindle. As the webs are provided with a hollow core, thespindle is provided with a plug member 41 fixed thereto and driven into the ends of the web core, securely mounting the web in position upon the spindle.

12 represents a pulley fixed to the spindle, preferably at one end thereof, and outside of the right hand frame, said pulley being provided with an annular groove to receive the strap 13. ()ne end of the strap is secured to a barof the horizontally projected frame 41, see Fig. 2, while the other end of the strap 43 is secured to acollar 45 mounted upon a stud shaft 16 supported in the side frame. The collar is loosely mounted upon the stud shaft or bolt and is fixed to a worm wheel 47 likewise loosely mounted on the stud bolt 46 and in mesh with a worm or screw member 48 journaled in a bracket 49 and provided with a hand wheel 50, for 1'0- tating the screw and in consequence the the usage of the printed matter. The frame 44 is of bar or skeleton form, provided with a cross plate 50 at its outer extremity.

51 represents a screw journaled in the cross head 50 and bracket extension 39 and provided with a hand wheel 52 for rotating 54 represents an arm having a' threaded engagement .with the screw '51, its

the same.

free end yoked and adapted to engage be- .tween the collars 53 fixed to 'the spindle '40..

Thus'as the hand wheel 52 is rotated', thei-." arm 53 will be fed by the screw 51, come; spondingly moving the spindle'40,pr oviding'r a lateral adjustment of the web. The yoke corresponding to the notch in the bearings of the spindle to enable the spindle to be removed in an upward angular direction. The strap 43 at its end connecting with the collar is notched to enable the same to be 'readily withdrawn from its collar connection releasing the pulley 42. As illustrated,

:the arm 54 is slidably mounted upon the bars of the frame extension 44,'to maintain the same in a proper position relative-with the axial line of the spindle 40. This web tension and adjusting means comprise a very simple arrangement, durable and very ac? curate and is a very important factor in the successful operation of the press. The paper as it is unwound from the-web 1 travels upwardly and between the perforating'instrumentalities comprising the following elements:

Perforating mechtmism.6l represents a-. shaft journaled in bearings formed 1n the side frame 16, the-shaft carrying the gear 37 in mesh with the train "heretofore described. Upon'this shaft are mounted the lower perforating rolls, adapted to register with companion perforating rolls mounted upon-a shaft supportedij-parallel above the shaft 61.

62, 63,.represent bearing" plates mounted upon the side frame-16 and an whlch the upper shaft 64 is journaled. These bearing plates are removably secured to the side frames and also serve as means for mamtaining the journaled bronzes of the shaft 61, i'n'position within the side frame. This enables the perforating mechanism to be readily removed for changing the perforating rolls, for, as illustrated, the rolls have a permanent location and ap'redetermined lateral position of the various punch elements relative to each other. It is obvious, however, that the perforating rolls could be constructed to be readily ad ustable upon tion relative to the travel of the paper rto perforate the same at various points within the margin line of the paper.

65, 65, represent gears fixed to the'sh'aft 61 in mesh with gears 66, 66, fixed upon the shaft 64, for conveying motion thereto and provide a double set of transmission between shafts 61 and 64 to insure positive results and avoid, as far as possible, flexing or distorting strains of the shafts which might have a tendency to interfere with the accurate registration of the punching element of the perforating rolls. To accurately register and aline the lower perforating rolls .withthe upper, I provide means for laterally I 4," provided with an annular flange secured to the side frame 16 with the bore of the thimble screw threaded.

limbs of the arm 54 are angled a direction 67 i represents a sleeve loosely mounted upon'a stud projection of the shaft 61, which is screw threaded engaging with the threads of the thimble 68, whereby the rotation of the sleeve a, movement to the right or leftis had according to the direction of rotation'thereof. Y I

71 represents-a hand hold formed integral with the sleeve for rotating the same.

As illustrated in Fig. 4, the gear 37 is loosely mounted on the shaft 61 with frictlon clutch mechanism provided for clamping the gear to its shaft to control the operation of the perforating rolls. By this means the perforating rolls can'be' readily thrown into and out of commission. 4

' The preferred form of clutch mechanism, as illustrated, comprises the following ele- 1'10 ments :The inner periphery of the gear 37 1s provided with an inclined annulus 72, adapted to engage with the inclined pe-' riphery. of the friction disk 73. This friction disk 73 is keyed and splined upon the shaft 61. 74 represents a screw'rod, screw threaded into the end of shaft 61 and provided with an annular flange 75, one side thereof engaging a collar 76, fixed to the hub of the disk 73. 77 represents a hand wheel fixed upon the screw rod 74, with its hub engagingthe collar 76. Thus, by rotating the hand wheel 77- the disk 73'6an be fed into and outof its locking engage ment with friction surface of-the gear 37. To prevent accidental release or rotation of the hand wheel, I provide a lock vise 78, mounted uponthe side frame, having jaws adapted to engage the hand wheel for locking said hand wheel against rotation. 130

The construction of this hand wheel locking mechanism may be'of any; desired form, .butthe. preferred type herein illustrated, which is utilized to block the varii-us .adjusting hand wheels of the machinefof which all arethe duplicates, ill be more clearly described in detail herein,

The perforating rolls herein illustrated are formed in unitary pairs for providingeight -perforations in a relativespacedlater'al plane, but is obvious that the number of perforations or relative spacing may be of any number or degree to answer the requirements. But as t is essential to provide a substantial deslgn'of construction to prevent distortmentor displacement of the co acting elements by an improper registration nected to the bracket plates 62. 63. The perforating rolls 2-, 3, as illustrated in Fig. 4, are arranged in unitary pairs and arranged to make eight perforations in a lateral plane. Theupper rolls 2 are provided with the punch pins 80, each seating within an orifice formed in the periphery of the roll, see Figs. 4, 6 and 7, with the; punch pins of sleeveformation with the bore thereof screw threaded to receive the adjusting screws 82, whereby the punching end of the punch pins 80 can be accurately adjusted in their 'projecting distance from the periphery of the r ll 2 to provide for the proper registration of the punch pins with their die elements carried by a companion roll 3, mounted on shaft 61. The rolls 2 are provided with notches cut into the periphery thereof'to enable locking screws 83 to engage thepunch pins 80 at right angles thereto; As illus v trated, the perforating rolls are provided with two punching elements for making two' perforations upon each rotation of tlie roll. m

ihe lower perforating rolls are provided with die plates-81. seated within notchesformed in the periphery of the roll 3 and the rim ofthe roll 3 is'provided with clearancc orifices 84.- alined with the die orifices, providing a discharge spout for the punch cuttings.

\Yith my form of punch pins of sleeve formation with an adjusting screw concen tric thcrewitlnI am enabledto provide a seat for the punch pins within the rolls with the punch pins engaged against the same at. all times. prevent their displacementand overcome many diliiculties heretofore exper'ienced in perforating instrumentalities of'this'class and in which the delicacy of the adjustment of the punch pin relatively to 'i and with its coacting die element is micrometrically obtained and thus maintained.

The continuity of the operation of the press is not disturbed to the degree heretofore experienced under existing methods and obviates what mightbe termed hand repairing of the the members by the operator for producing clean cut perforations. It would be possible to more elaborately discuss the advantages of my improvement in this capacity, but it is deemed that the sufiicient for the purposes herein. In-the arrangement shown the perforating rolls are the first to act upon the paper in its travel through the machine, but it is obvious that the perforating may be accomv plished at any stage and occupies the position-as one of convenience for access to'the perforating rolls to ad ust the punch pins or remove the rolls to change from one unitarily spaced set to that of the second.

From the perforating rolls, the paper travels through the printing rolls i, 5, these rolls are driven and inked and comprise the following 1nstrumental1t1es:

foregoing is C'g Zinder adjzistment.90 represents a shaft supporting and rotating the printing roll or cylinder at, see Figs; 8 and 9, mounted in the eccentric bushings 91,,j0urnaled within the side frames 16, and upon one end of the shaft 90 there is fixed the gear 34,

forming a member of the train heretofore described. The gear 34 is of two part form with one member adjustable upon the other and comprises a hub member 92', which is keyed to the shaft 90, and a rimmed member 93,'h aving its web provided with semicircular slots 94, through each of which, see

Fig. 1, abolt 95 passes. This enablesthe shaftandfiits roll to be adjusted rotatively without disturbing the correlative't-ime function, of the rolls and without disturbing the mtermesh of the-gear.-

' It is very desirable to roll, move out of engagement wit-h the have the printing I platen rollfor inserting-new printing plates or throwing the'same. out of commission, thisjbe'ing' accomplished as follows :-96

I'QPI'ESGIHJ rack segments fixed'to each of the eccentric bushings 91, each having its teeth intermeshed with a rack pinion 97, fixed to the rock shaft- 98-, supported in the .side f'rame 16 and projectedpbeyond one side thereof. Thus as the rock"shaft 98 is zrotated it will rotate the gears 97'. and their 'intermeshing rack segments "correspondingly rotating the eccentric bushings changing the axial line of .shaft- 90, andits-i'mpressionroll correspondingly to and from the platen roll. 99 represents .a quadrant fixed to side frame providedwith a semicircular slot 100, through which a lock pin 101 projects, forming a locking member for locking the rock shaft 98 in any adjusted position. The lock pin 101 projects through an orifice formed in. the handle lever 102 with one end provided with a hand wheel 103 and its opposite end with a nut 104. By rotating the hand wheel the pin, and nut can be tightened or released to allow the pin to slide freely in they semi-circular slot 100 and also permit movement of the hand lever. By this means the printing roll can be easily and conveniently moved to and from its companion platen roll for renewing 'or changing the'texture of the tippet wound on the periphery of the platen roll. The printing roll may be provided upon its periphery with axially arranged grooves or T slots to accommodate register'ing hooks used for securing the impres-,

fion or electro-type plate. The method of securing the impression or printing plates is not herein illustrated, but. as this feature is not a part of my invention, only forming a component part of the machine as a whole, specific illustration or detailed. de-

"-scription need not be given further consideration herein. 105 represents a shaftfor supporting and rotating the platen roll 5, journaled in bearings. formed inthe side frames 16. This shaft is'provided with the gear 33 which is intermeshed with the gear 34, forming members of the train of gearing heretofore described. -To control the density of'the impression and to define'va- 'riable limits of printing roll engagement or A distributing hingedly supported at each end to the ink approach toward each other, I provide means for laterally adjustingthe platen,

- loosely mounted upon a stud projection formed on the end of shaft '105,to provide a; shoulder 111 against whichotheendflof the thimble 106 engages. The opposite. end of the thimble engages a nut 112, screw threaded upon the stud projection of shaft 105. 113 represents a circular hand hold formed integral with the thimble or sleeve v 106. The sleeve has a screw threaded en gagement with the thimble and thereby upon its rotation lateral movements are directed either to right or left as desired. The printing and platen rolls are of sec- .tional form as illustrated, but this relates primarily to a feature of good mechanical design comprising two cylindrical members telescopically engaged and mounted upon the driving shaft. 114 represent disksfixed to the ends, 'ofthe platen roll each having inclined periphery of a corresponding anand in'the same plane while the print- 1n 11% likewise having angular periphery disposed in the same plane as their companion disks 114. The highest elevation of the. an-

roll 4 is; provided with similar disks gle projecting beyond the periphery of the roll upon which they are mounted defining the limits from which a set of rolls may be separated by this adjusting mechanism. Thus it will be' seen that the adjustingof the platen roll5 laterally will change the surface engagement of the two sets of disks, consequently Varying the relative spacing of the rolls and the pressure of contact of the printing'r'oll upon the yielding surface of the platenroll, thereby governing the degree of roll or cylinder approach to determine the density of the impression. The disks and their, adjustment may also bedefined'as means for providing variable restraining limits of cylinder approach.

voir to the impression roll although a preferred embodiment herein illustrated relates primarily in the means for controlling the film of deposited upon the surface of the main ink receiving and distributing roll.

1 120 represents the frame of one of the ink fountains or reservoirs adjustably mounted upon suitable supports formed in the side frames 16. Within this frame is mounted a dlstributing roll 121 which is intermittently rotated by mechanism of a pawl and ratchet type common in producing the feed of this type of roll which will hereinafter be more fully described in detail.

' 122 represents a movable wall of the ink reservoir extending parallel with the ink roll 121 and preferably reservoir frame 120. This swinging frame or wall is locked in its'position by means of the set screws 123 engaging with a lug projection extending from the swinging wall 122 and screw threaded into a downwardly projecting web of the ink reservoir frame 120, see Fig. 15. The swinging wall has an inclined surface forming a spout between it and the ink distributing roll 121 into which the ink is deposited. Upon this inclined surface of the swinging wall a flexible plate 124 is mounted, having one edge thereof directed toward the periphery of the ink distributing roll 121 and the clearance between this plate and periphery of the roll 121 defines the degree of thickness of the ink film. To produce a uniform degree of film over the entire ink receiving surface of the ink roll 121'or to variably regulate the degree of film thickness, I provide a series of conically I pointed set screws 125, horizontally projecting through the. swinging wall of the ink reservoir, adapted to engage with the ink plate 124. By this meansthe plate can be delicately adjusted throughout its entire length owing to its, flexibility and thereby control the amount'of ink deposit upon the ink di tributing r011 121. .126 represents an oscillating ink distributing roll, see Figs. 1 and 3, also Fig. l. which roll is journaled within yoke arms 121' at each end of the roll, vvihich yoke arms are fixed to the rock shaft 128. The mechanism for locking said shaft distributing'mechanism to get a uniform distribution and thorough kneading of the ink. The ink distributing roll 129 is in frictional contact with the distributing roll 130. The roll 130 is a power driven roll receiving goits rotation by means of a gear 131 in mesh with a gear with the latter gear in mesh with gear 31 of the train heretofore described.

133 represents anink distributing roll positioned between the printing roll 4 and ink distributing roll 130 and frictionally engaging said rolls for distributing the ink from the inking roll 130 to the printing roll. This combination of ink distributing rolls is common in the art and comprises a com-' bination producing the most satisfactory re suits for the class of work for which the press is intended. It being understood; however that various other types of inking devices may be employed without departing from the features of my invention. 3

From the first set of printing rolls the paper passes to a second set of printing rolls T, as heretofore referred to for printing upon the reverse side from that of the first set or printing operation with the instrumcntalities employed constructed substantially the same as those described for the first set'from whence the paper passes to a third set of printing inst-rumentalitics, which, in this character of press, is utilized for indicating a manifold number .and which printing instrumentalities maybe substantially the same as those heretofore dcsciibed for the first set and owing to such duplication of elements further detailed de- ,.scription thereof is hereby omitted. In each instance the power 'driv'en ink distributing rolls are rotated by gearing in train with the driving gear mounted on the shaftof the respective printing roll of a given set,

It is further obvious that the printing roll of any one or more of the printing sets may be thrown out of commission if such impres' sion is not desired or required for a given class of work without interfering with the remaining set or sets.

C '0 728602165 re n'zmz 562 i 12 g mechanism .From the third set of impression'rolls the paper advances through the numbering instrumentalities for consecutively numbering each impression or signature which, in this instance, is the final operation upon the web,

but its position and rank can be changed.

134 represents a shaft journaled in the side frames rotated by gear 135, see Fig. 3, with said gear in mesh with a gear 136, mounted on a shaft 137, the opposite end of said shaft carrying the gear :27 in mesh with the train of gearing heretofore described. The gear 135 is of two part form, the hub member being keyed to the shaft 131, with the rim or toothed member loose .upon the shaft. The two members are adapted to be frictionally clamped together thereby providing clutch mechanism for controlling the rotation of shaft 13-1. This mechanism is substantially the same as that heretofore described for controlling the rotation of one of the shafts of the perforating mechanism, and, therefore. further detailed description is herein omitted. Thus it will be seen that the shaft 131 carrying the numbering heads can be readily thrown out of commission while the machine is in operation or the same can be thrown into commission as desired.

In printing autographic' register strips it is desirable to consecutively number each signature for record purposes or other uses.

The following mechanism is employed in my machine and comprises a rotatable head adjustably mounted upon the shaft 134-, with the head containing a series of numbering disks forming a numbering unit, and, as illustrated, the head is providedwith two numbering units to printtwo numbers upon each rotation of the shaft and head, but it is obvious that any number of units may be employed as the occasion demands, this be ing governed by the length of each signature and the correlative rotation of the numbering head.

11-0 represents type disks or wheels which may be of any number desired, and, as illustrated, in Fig. 12, siX type wheels are provided to each unit. The first wheel of the unit has a series of pins 141, projecting from one side thereof, adapted toengage with lugs 142 projecting from the arm H3 m .-unted npcn the slide rod 1 14, to rotate the numbering wheel one point at each engagement with a particular pin in consecutive order. Thisengagement,iisimilar to the tooth intermesh of gears, and thereby provides a very positive and accurate rotation in step form cf the tyie w'l'ieels for con se tivcly lu'inging a number or character into printing position. The first wheel of the series printing the units, the second the tens. -etc.. throughout the series, and each wheel is required to make a complete rotation before a successive wheel is rctated.

'The type wheels are loosely j ournaled upon type wheel, and in its rotation it will engage with the cam 150, projecting from the hub of the type head, see Fig. 12, directing the pawl laterally so as'to move the same into engagement with a notch of an adja cent type wheel and advancing the same one step upon each rotation of the first type wheel or the number of steps dependent upon the number of cams 150 employed in the circuit of type wheel rotation. Each type wheel is provided upon oneside with a similar: pawl for shifting its next adj acent type wheel when the opposite pawl of an opposite type wheel coincidentally registers therewith.

I In the form shown with the provision of two type wheel units, each wheel is advanced two steps in presenting. the type characters from one printing position to a second on each rotation of the shaft, in

' which one unit wouldprint'the odd numbers and the second the even numbers for a consecutive printing upon the strip, but

. the number of units maybe varied as well as the. relative rotation between the'numbering headand travel of the sheet for accomplishing the'con secutive number printing or two or more successive signatures can be printed with the same number by changing the number of lugs 142 projecting from the arm 143. It is also obvious that any num: ber of printing heads maybe mounted upon the shaft 134 commensurate withthe par? ticular printing job. The arm 143 is frictionally clamped upon the slide rod 144,. by slotting'its sleeve 151, as illustrated in i Fig. 11, and providing the hand screw 152,

engaging with theprojecting ears opposite the sleeve slot. Thus by shifting the arm to the left, from the illustration Fig. 10, the

- lugs 142 can be disengaged from the type wheel pins 141, discontinuing the'step rotation of the type wheels.

. It is desirable at times to automatically discontinue the consecutive numbering for a slight period, this being advantageous in printing autographio register signatures which are of a materially reduced length from the web supplying the printing machine, and thereby allow a few signatures as waste in loading and ahmngthe same within an autographic register, without destroying the consecutively numbered signatures for such. register loading purpose. Therefore, to automatically discontinue the consecutive number printing for a predetermined interval without interruption to the signature printing, I provide the follow-- ing instrumentalities :154 represents a bevel gear fixed upon the shaft 134, carrying the numbering head, which is in mesh with a beveled gear 155, fixed upon the shaft 156, see Figs. 1 and 10, said shaft being journaled in suitable bearings fixed t0 the side frame of the machine. 157 represents a wormfixed upon the shaft 156, having its teeth in mesh with a worm wheel 158, rotatable upon a stud shaft mounted within the side frame. The periphery of the worm wheel is provided with an annular groove for receiving a lock bolt for clamping a tripping dog 159, upon the periphery of said worm wheel. The number of teeth serving as a gage in setting the tripping dog or dogs, if more than one is employed, for defining the number of consecutive number printing operations to be had priorto each unconsecutively numbered interval. The tripping dog in its circuitous path engages with the arm of the lever 160, projected in the path of the tripping dog, with the opposite arm of the lever connectedwith the slide rod 144, thus moving the slide rod to the left and maintaining the same. in such 162 represents a spring engagmg a gage the type wheel shifting mechanism.

The numbering units in their rotation engage with ink distributing roller mechanism, which is substantially the same type of mechanism as that heretofore described for 1 distributing ink to the main printing rollers and the rotating membersof the ink d1stributing mechanism receive their motion by means of the gears 163, 164, intermeshing.

with each other, and ar 164 intermeshed l e with the gear 135, vr'otziing shaft 134 carrying the numbering heads, see Fig. 3. 1

As has been heretofore described, the nk distributing mechanism of each printing unit is provided with a ratchet fed fountain ink distributing roll and a reciprocating roll swinging from the fountainroll to an ink distributing roll of the series'to provide an interrupted transfer of ink from the fountain roll to the series of, distributing rolls which distribution of inkis common in printing presses, and well known to the art,

and, therefore, to provide the intermittent rotation of thefountain roll, and the oscillating movement of the distributing roll, I provide the following actuating-elements:

In this regard it might be added that I provide a main actuating member having tributary elements radiating therefrom and connected with respective Oscillating ink distributing rolls and fountain rolls. which provides a relative cooperation of the various ink distributing units of the machine.

166 represents a shaft upon which the gear 26, forming one member of the main driving train, is fixed. The shaft extending across the machine and journaled in bearings formed in both sides of the frame, (see Figs. 1, 5 and 16). Near the opposite end of said shaft 166, a cam wheel 167 is mounted, said cam engaging a roller 168 mounted upon the lever 169, with the lever pivoted to a suitable bracket projection extended from the main frame.

170 represents a tension rod engaging with the rock lever 169, to maintain the roller 168 in peripheral engagement with the cam 167. Upon the rock lever 169 a series of connecting rods are pivotally mounted serving as branches extending toward thevarious ink distributing roller units.

171 represents one of these rods extended taward the inking mechanism A and connected to the rock arm 172. which in turn is fixed to a shaft 128. To this shaft is fixed a pair of yokeaarms 127, which support the ink distributing roll 126 for rocking the same from the fountain roll 121 to the ink distributing roll 129. This cam is so de-' signed as to provide a period of engagement of the oscillating ink distributing roll,with each of its coengaging ink rolls, as, for instance on one-half of the revolution of the.

cam 167, the oscillating roll 126 will be in engagement with the fountain roll 121, and during the remainder half of the rotation of the cam the roll 126 will be in engagement with the ink distributing roll 129. This action is maintained with all of the oscillating rolls of the various ink units of the,

press, and therefore, special reference ineach instance need not be made herein.

17 3 represents a second branch connecting rod pivotally connected with the rock lever 169, and with the rock lever 174 of bell crank form and pivotally mounted upon the side frame. The bell crank lever 17 4' has a second connecting rod 17 5 pivotally connected therewith, with the opposite end of said rod connected to a rock arm 176 for oscillating the ink distributing roll 126 of the inking mechanism B. This rock arm 176 is connected to a rock shaft 128" and the said shaft is provided with a pair of yokearms for supporting and journaling the oscillating roll 126 for moving the same to and from the fountain roll 121" and the ink distributing roll 129 of said unit' B.

177 represents a third branch connecting rod, one end pivotally connected to the rock lever 169, with its opposite end pivotally connected to a bell crank lever 178.

183 represents a connecting rod pivotally mounted upon an arm of the bell crank lever 178. The opposite end of the connecting rod 183 is pivotally connected to a rock arm 184, for oscillating the ink distributing roll 126 of the inking mechanism for distributing ink to the numbering disks. The rock arm 184 is connected to a rock shaft 128 with said shaft provided with a pair of arms for journaling and supporting said ink distributing roll 126 the roll moving to and from its fountain roll 121 and ink distributing roll 129 As illustrated, the connecting arms of the series are each adjustably connected to their respective rock arms to properly gage the movement of the oscillating ink distributing roll and which connection may be of any well known form common in the art.

The fountain rolls of each of the ink distributing mechanisms are intermittently rotated and preferably by ratchet mechanism. This intermittent rotation of fountain roll is likewise common in the art of printing presses. 185 represents an eccentric fixed upon the shaft 166 and 186 represents a pitman engaging with the eccentric 185, with the pitman pivgtally connected to a Y-lever 187, suitably pivoted to the side frame. The arms of said Y-lever are each connected to a branch connecting rod for actuating the fountain rolls of the ink distributing mechanis'ms A, B and C. 188 represents a connecting rod, one end connected to the Y-lever the opposite end to a pawl-carrying arm 189, of the ink distributing unit A, with its pawl engaging with a ratchet wheel fixed to the shaft carrying the fountain roll 121.

190 represents a branch connecting rod, one end pivotally connected with a second arm of the Y-lever 187, with its opposite end pivotally connected to a pawl carrying arm 191 with its pawl engaged wlth a ratchet wheel fixed to the shaft supporting the fountain roll 121 of the ink distributing unit C.

192 represents a branch connecting rod,- one end thereof pivotally connected to the third arm of the Y-Iever 187, wlth its opposite end pivotally connected to the pawl carrying arm 193. The pawl of said arm engaging with the ratchet wheel fixed on the shaft of the fountain roll 121 of the 1nk distributing unit B.

As illustrated, the three branch connecting rods have each end adjustably connected jecting from the pitman 186 with the opposite end of said rod connected to one arm of roller20+l is journaled in the guide bars 205 r the bell crank lever 195, pivotally supported upon the side frames.

wheel fixed to the shaft carrying the fountain roll 121 of the numbering wheel inking mechanism.

The printing cylinders or rolls of each printing unit, namely printing cylinders 4, 6 and 8 are each provided with means for moving tlie same away from their platen roll, the preferably form of mechanism having been heretofore described, which comprises eccentric bushings .supported within the side frames and forming bearings for the shafts of the cylinders with each eccentric bushing having a rack segment engaging with a rack pinion and handle means for rotating the shaft supporting relative rack pinions, together 'with means for locking the handle in any adjusted position, and it is thought that detailed description in each instance is unnecessary herein. Likewise it may be said that all of the rotating hand wheels controlling clutch mechanism are provided with locking instrumentalities for rigidly locking each respective hand wheel against accidental rotation.

The continuous length of paper after it has passed through the printing rolls is rewebbed and wound around a core 200 having its trunnions movable vertically in guide' bars fixed to the side frame. The periphery of the web engages intermediately upon the rollers 201, 20-2 rotated in the same direction by the gears 22, 23. Gear 22 being fixed to the axis of roller 201 while gear 23 is fixed to the axis of roller 202. A weighted and vertically movable relatively with the increasing diameter of the Web which offers suflicient tension to wind the roll with the desired degree of tautness. The speed and ratio of the gears 22, 23 is proportionate to the feed of the paper relatively with the speed of the printing rollers so as not to otl'er any pulling strains upon the paper. The web being loosely supported and rotated hvfrirti m will slip upon the peripheries of the rollers to prcventexcessive pull of the paper as he diameter of the web increases.

As a series of printingunits are herein shown and described which are more or less required for the particular kind of printing for which the machine is designed, duplicate elements are contained in the various units, therefore, specific inference in each instance as to details. is regarded superfluous herein, but such duplicate elements can be regarded as components in each printing unit.

The foregoing description includes and the drawings disclose perforating mechanism, numbering mechanism and other diverse features not herein claimed, which are separable herefroniand classifiable in other divisions and reference to thenumbering mechanism, which in a unit machine can be .combined herewith, is had in a copending application, filed July 1,' 1912, Serial No.
