WILLIAM .ASSHETON, 0F BALTIMORE, MARYLAND.

WEB PRINTING AND WINDING MECHANISM.

Application led March 16, 1929. Serial No. 825,454.

To all 'whom z't may concern:

Be it known that WILLIAM AssHEToN, a'

citizen of the United States, residing at Baltimore, in the State of Maryland, has invented certain new and useful Improvements in Web Printingand Winding Mechanisms, of which the `following 4is a /speciication.

. This invention relates to -an improved printing, cuttingand Winding machine and paper, allow the printing ink to dry, then trim or cut the web into proper widths and wind the printed land dried web into close rolls, thereby performing the several op erations simultaneously on the same web tion.

and materially reducing the-cost ofproduc- The machine is especially designed for printing sales-checks which are jemployed by merchants in making records of sales to various customers, but may be as lreadily used for making repeated impressions on a web Jfor any purpose.

eretofore, it has been the practice to A print sales checks upon a web and wind the same into a loose roll butthese operations` arenot satisfactory because the ink oil-sets and further because the loose; roll must'be unwound and trimmed and the strip again wound into a Iclose roll under tension in order that the requird'number of checks may be wound into a 'roll of smallv diameter readfor use in the machines or registers in whic -they are employed. 4This close rolling cannot be done `while the ink is wet because of the large number of dlt-sets that result,

consequently under thel old practice 'it has been necessary to resort to separate trimming and winding operations after .the ink has dried.

By means of my invention, I am able to carry on. the several operations of printing, drying, trimming and windln the complete sales checks and thereby lavoid the expense of the additional operations and the delay incident thereto.

The invention is illustrated in the accompanying drawings, where1n,-

Fig. 1; shows the im roved machine .in`

siderelevation, as viewe from one side of Fig. 2. illustrates the same alsov inside ele- I vation but as viewed from the opposite side operations of printing plural checks side-by j ing-rolls with its .bearing block, and

Fig. 9. shows in a diagrammatic way the "0 side` ona single web and the successive oper" ations of producing folds i'n the printed web toffallow thexinkto dry and then placing the yweb under tension, trimming,l cutting and then spooling the two rows of checks. Referring to the drawing the numeral 10, designates two side frames of the machine which are sustained on a suitable base 11, and which extend vertically. i

A horizontal shaft 12,.extends crosswise between and has-bearing in the two vertical*A side frames. For the purpose Vof the present invention this horizontal shaft 12, may be regarded'as the drivin 13, being indicated on the for driving the same. l `The shaft 12 carries a platen-roll 14, which is revolved as the shafbturns, and one end of this same shaft carries a gearo 15 which latter meshes with and drives an idle pinion 16, on a short horizontal stubshaft orA stem 17 which.,projects dfrom the .side of the frame" 10. 7 The pinion H16, meshes with and drivesl a gear 18,i on a' horizontal shaft 19 that extends crosswise of the machine with'beari'ngs in the two side frames, and the said shaft 19 carries atension roll 20. 1

Above the shaft 19 the frames sustain an-J 10o otherv horizontal shaft 21, nn which two spaced-apart circular headsf22 are carried, which latter are directly over the roll 20 and are designed to coact with the same in taking the web from the platen roll14.

A gear 23 is provided on one end of the shaft 21 whichgear meshes with and is driven by the. gear 18, on` the shaft 19, and a sprocket wheel 24 is provided on the opposite endv of -said shaft. 21, for a 4that. will presently be explained. n I I The/ shafts 19 and 21 arev carried in bearend of the shaft purpose 11o ing-boxes at the outersides of the two frames whereby the tension-roll 20 and heads 22 may be properly adjusted with respect to each other. 1

It will thus be understood that the tension roll 20 and heads 22 are driven from the gear through the idler pinion 16.

" Above the drive-shaft 12, there is provided a cylinder-shaft 25 which extends horizontally across the machine from one side frame to the other and this shaft is supported in removable bracket-bearings 26 which may rea-dilybe removed for a purpose presently to beexplained.

OneA end of said upper shaft 25, carries a gear 27 which meshes with and is`driven by the gear 15 on the shaft 12,-the gears 27 and 15 being of equal diameter and having the same number of teeth in order that a revolution of shaft 12 willH cause a revolution of shaft 25.

The shaft 25 carries na printing cylinder 28, which may be attached thereto in `any well-known manner, and this cylinder and the platen-roll 14 are driven so each will complete a revolution at the same time.

Above the gear 27, which drives the printing cylinder, there is provided an idlergear 29, as shown in Fig. 1, of the drawing, which idler meshes with and is driven by the gear 1 27 and said idler-gear 29 drives. a gear 30 on the outer end of a horizont-al shaft 31.

The shaft 31, extends all the way across the machine and carries an ink-distributing roll 32, and on its far end, this shaft is provided with a grooved cam 33 in which a roller 34 on the end of a stationary arm `35 projects as shown 1n Figs. 2.and 3 of the drawings.

, The shaft 31 is sustained inits opposite plained, are all carried in a specially designed bearing structure which will now lbe explained, reference being made particularly to Figs. 1,4, 6 and 7 of the drawings.

Each side frame 10 has a\curved bearingl flange 36, and is also provided with a curved bearing-ledge 37 as best illustrated in Figs.

6 and 7 of the drawings. The bearingfiange f hasone bearing-recess` 38 with a slot 39 at one side thereof and a corresponding recess and slot is provided in the opposite side frame so that bearing-blocks 40, on the shaft 31, may fit-said recesses 38 while the shaft itself may project through said slots 39 to the outer sides of the side Other bearing recesses 41, are provided in the flanges 3 6 for the reception of bearingblocks 42 so that a plurality of shafts 43, 44, 45 and 46, may be mounted horizontally between said side 'frameswhereby to sustain rolls 47, 48, 49 and 50 respectively.

`Betweent-he roll 32, and the'printing cylinder 28, two horizontal cross-shafts 51 and 52 are mounted'in bearing-blocks 53 `that are carried in bearing-recesses 54, in the ledge 37. Theseshafts 51 and 52 carry rolls 55,

and 56, the circumferences of which latter rolls contact with the roll 32 and also with the printing-face of the cylinder 28.

, On top of the two side frames 10 and extending horizontally, there iS provided an ink receptacle 5,7, 'm lwhich there is a horizontal ink-feeding-roll58. This'ink roll 58 projects slightly through an opening in the rear of the ink-receptacle for a purpose, that will presently be explained.

One Iend of the shaft 59 on which theV inkfeeding roll 58 is mounted, projects through an end-wall of the ink-receptacle and carries a ratchet-wheel 60 and a lever 61'is also loosely mounted on the end of said shaft 59 and said lever carries a pawl 62 which engages said ratchet-wheel, The. vlever 61,'j

normally lies in the path of a pin 63 that projects horizontally from a cam 64 on the end of Shaft 25.

From the foregoing explanation it will be understood that as cam 64 revolves, the pin w63 will intermittently strike the lever 61 and swing the lower end laterally or to the right, as viewed in Fig. 1 of the drawing. This lateral swing of lever 61 causes the pawl 62 to engage the ratchet- Wheel 60 and impart a partial rotation to the latter and also to the shaft 59 and the ink-roll 58, so that upon each revolution .of the cam 64, the ink-roll 58 will be given a partial rotation in the inkreceptacle.

Beneath the ink-receptacle 57, there is a horizontal rock-shaft 65, which has bearing in the two side-frames 10 and each end of this shaft carries an arm 66 at the inner side of each frame, which arms extend upwardly and rearwardly with respect to the ink-receptacle. These arms 66 carry a horizontal roll 67 which latter has position between the ink-roll 58, and the roll 47 as best seen in Fig. 4 of the drawings, and in operation this roll 67 is designed to swing to and contact with the ink-roll 58 and then swing from said roll 58 and engagey the roll 47 so as to pick up ink from roll 58 and then transfer that ink to roll 47. The means for effecting this operation of the roll 67 is illustrated in Figs. 1. 3 and 4 lof the drawings, and will now be briefly described.

One end of the shaft 6.5, carries an arm 68, which latter depends at the outer side -j hangs pendantly from the'outer end of the roll-shaft 59 and the lower end of said lever of the side framecso that its lower end has position at the side of cam 64. A roller 69, is carried by the arm 68 and said roller engages and ridges on th face of the cam.

As the cam revolves, it swings the arm68,

a spring 70 serving to keep the roller 69- in engagement with the cam, and the arm rocks shaft 65, and swings the arms 66 and the roller 67. During this movement the roller 67 is sw'ung away from the ink roll `58 and into contact with the roll'47. As kthe cam continues lto revolve the roll 67 swings back to the ink roll 58 and while it is in contact therewith said ink-roll `is given a partial turn by the operation of the pin 63'0n the lever 61. -InV this way the roll 67 4travels back and `forth between fthe two rolls 58 and 47 and carries inkfrom l the former to the latter.

A spring 71,keeps the lever 61 yieldingly .pressed toward the path of the traveling pin63. 7

Roll 47 is driven through its contact with -the roll 32 which latter is positively driven by the pinion 30 and ink is transferred from roll-47 to the roll 32.

The roll 32 is carried on the shaft 31 and this shaft-also carries the grooved cam 33 onl its outer end. Therefore, as shaft 31 revolves it is also given a longitudinal reciprocating movement v.because of the grooved cam 33 and the stationary arm 35 and roller 34. In this way roll 32 is re- 4 -ciprocated with` respectrto the rolls 47, 55,

56 and 48fwith all of which it contacts as.,- it revolves and the inkr is therefore thoroughly distributed over the several rolls. y

Roll 48 drives therolls 49 -andj'50 respectively and transfers. ink to the latter and the roll 50 is provided for the purpose-of supplying ink for a numbering drive, to`

which further reference ywill presently be made. I, is',

The several rolls 47 , j 32, 48, 49 an'd- 50 are carried by the bearing- blocks 40 and 42 which latter are seated inthe recesses 38 and 41 and after thesey blocks have been Y placed in their respective recesses a bar 72,-

is secured against the curved bearing-flange 36 andA said bar hasl a retainingscrew 73, foreach bearing-block wherebyit may be screwed against said block and hold the latter in place in its recess.

-In a similar manner the blocks 53 for yshafts 51 and 52 are held in the recesses 54 by means of a bar 74 secured to the 'bearing-ledge 37 and retaining screws 75 engage each block. l

The base 11, sustains a horizont-a1 crossshaft 76, (shown in Fig. 4kof the drawing) on which a roll or web or paper 77 is mounted, and it is fromvvthis roll that the yweb is f ed through lthe machine for printing, drying, trimming and final spooling into complete rolls ofvsales-checks ready for the registers which are used by the merchant. From the roll 77 the web' 78 is passed up over the platen-.roll 14 and beneath the impression cylinder 28 which performs the printing operation. The web after being printed passes between the roll 20 and the two spaced-apartv heads 22 on the, shaft 21. The heads 22are so spaced as to en# gage the opposite marginal edges of the web at op osite sides of the printed area sov that t e fresh ink will not besmeared by contact with any surface of a pulling roll. After the web passes between the pulling roll 20 and heads 21 it is deflected 'downwardly by means of two' spaced-apart heads 79 which are mounted'on'a cross-shaft 80 that is hung at each en'dn in swinging bearingbars 81; These bars (see Figs. 3 and 4 of the drawings) have their upperends pivot.

ally attached to the inner sides of\the side frames 10, and their lower ends hang pendantly, while the cross-shaft 80 is carried by the bars between the upper and lower ends thereof.

Springs 82, are connected to the lower ends of the bars 81 whereby to drawthe latter toward' the pulling-roll 20 so 4that the two heads 79 will have their vcircumferences, engaging the marginal edges of the printedwveb`v and will direct the latter downwardly. The shaft 80 and its two heads 7,9 are free to rotate and the freshly" printed-surface of the web is located betw'eenAsaid heads 79 and out of Contact with anly surface which might blur the fresh -1n 7 After the printed web 78, passes the pulling devices 20-22 and 79-80 its printed surface is given an opportunity to dry by means which will now be explained, referepee being made to Fig?. 4 of the drawing. Between thetwo side 'members ofthe base 11 and beneath the printingand pulling rolls, I provide a web-receiving receptacle 83. This receptacle is provided with an inclined partition-wall 84 which divides the 4is merely mounted to rotate freely but is not positively. driven As the prlnted web 78, travels downward- Aly-:from the pulling rolls it enters the trough 8 5 and, becauseof the inclined partition 84,

is'laid therein in a series of loose folds 90.

A quantity of printed web is thus accumulated in the trough when the machine is first v started and -prior to the feeding of the printed web from the trough to the tension and spooling devices which will presently be` l explained. r

l thereon.

Above the off-take end 86 of the receptacle 83, a guide roller 91 is mounted, and the web from the trough 85, is fed beneath roll 89, then up from the olf-take end 86 and around vidle roller 91 which latter serves as a mere guide.

From the idle guide roller 91, the'web extends upwardly and 1s passed over another guide roller 92 from which it then travels downwardly and passes around a l series oftension rolls 93, 94,95 and 96 respectively.

From the tension roll 96 the web is led to and passed around a second series of tension rollers 97,1 98, 99 and 100 'respectively A as shown in -`broken'lines in Fig. 1.of the drawing.

After( leaving the tension roll '100, the web extends upwardly and passes around a 'guide roll 101 from which latter it isy extended horizontally and passed between circular cutters v102 which are mounted in pairs on horizontal shafts 103, and 104: respectively.

I The cutters 102 on shaft 103 and those on shaft 104 are so spaced as to tigim the web to the proper width. In some instances I provide a pair of center cutters 105, as Indicated by broken lines in Figs. 3 and 5 of $0 the drawings, so that a web of sufficient width to receive two side-by-side impressions at one time from the impression cylinder 28 may be run through the machine and then severed by the center cutters 105,

J whereby two Webs of 0complete sales-'checks may be printed at onetime as clearly indicated in the diagrammatic view shown in' Fig. 9 of the drawings.

After the cutting, slitting or trimmingoperation by the, cutters 102 and 105, the

web passes between two guide rolls 106 and in case two rolls of sales-checks are being produced at once, one strip 107 is extended to and wound on a rod 108 while the other '55" strip 109 is wound on the rod 110.

By reference to F igs... 2, 3 and 5 of the drawings, it will be noted that rod 108, has one Aend pivotally connected to a squared head 111, at the inner end of a short shaft 112 and that the outerl end ,of said shaft B5 to rotate. The bearing screw 115 extends providel atwo part-check,one part" being 130 carries a gear 113. The other end of the lrod 108 isprovided with a conical recess 114 into which the pointed end of `a bearing screw`115, projects so as to permit the rod through the side frame of the machine and may quickly be withdrawn from engagement r with the rod-recess whereupon the rod may has one end pivotally attached to one end of 4a short shaft '116 while its other end is held by a bearing-screw 117.

A gear 118, is carried on thev outer end-y of the short shaft 116 and said latter gear l meshes with and drives an idler gear 119 which latter drives the gear 113 on shaft 112. f

Another idler gear 120, meshes with and drives the gear 118 while said latter gear is driven by another idler gear 121. A gear 122 on the outer end of cutter-shaft 10-1 drives the idler gear 121 and a gear 123 on the upper cutter-shaft 103, drives the gear 122.

The upper cutter-shaft 103 carries a clutch 124sy which is actuated bv a hand lever 125 while a sprocket-wheel 126 at the outer side of the clutch is driven by a lchain I127 from `the pulling" roll shaft 21.

Normally the cutter-shaft 1.03, is being drivento revolve the cutters or trimmers 102 and 105 simultaneously with the operation of the printing cylinder 28 so that the print- Jing, drying, trimming or cutting and spool-- ing' operations -all take place at the same time on the web, but when a Vroll with the Nrequired number of completed sales-checks ing this operation.Y

To this end, I provide ahorizontal crossshaft 128 whose outer end carries a gea-ix 129 whichmeshes with and is drivenby the gear 15.

The gear 128 is of the same diameteias that of the gears 15 and 27 so that all three gearsand their shafts revolve at the same c.

speed and begin and ycomplete their revoluv tions simultaneously.

The shaft 128, carries a head 130. for eachl numbering device that is employed,-one if a single .check is to be printed at a time on the `web but two if the web is to. receive .two side-by-side impressions at a time. In

the present instance two heads are presumed to be employed. l E

yIn printing sales Ichecks it is common to Separated from the other by a score or.per forated line to facilitate complete separation of a stub-part from the main check-part.

This means that each check-part should bear a number corresponding to-the number on the other check-part.

l/Vith this yobject in View, I provide each head 130 with two numbering devices 131, both of which will revolve with the head and each device being set with the same number exposed for the first' impression. Each numbering device has a trip pawl 132 by means of which its dials may be changed at each revolution. y

In case two checks are to be printed at a time, I provide two numbering devices one of which has dials or discs bearing even numbers only while the other will have dials or disks bearing odd numbers only so that d uplication of numbers will be avoided.

As shaft 128 and head or heads 130 is or are revolved the numbering devices 131 will be carried through a circular path and the numbering devices will contact with the ink-carrying roll 50, and thereby be inked after which it will swing around until itv is brought into contact with the web 78 at the number-impression station 133, shown `in Fig. 4 of the drawing, whereupon the number will be printed upon the web. After leaving the impression station the YVtrip-pawl 132, will sweep over a stationary trip-lug 134 which is carried on one end of a bar 135 and the numbering device will thus be advanced.

In this instance the-numbering devices for each check are located diametricallyI opposite each other so that at each half-revolution of the shafts each half of a check will be impressed with a like number.

This number operation at predetermined spaces on the web, in this instance, takes place before the web passes the printing cylinder and the operation thereafter upon the web is as has been heretofore explained, and as can be readily understood by reference to the diagrammatic illustration of the complete operation on the web as shown in Fig. 9 of the drawings.

Having described my invention, I claim,-

1. In a web printing mechanism the combination with a printing cylinder, ofmeans beyond the printing cylinder for piling the printed web in loose superposed folds to allow the ink thereon to dry suiiiciently to `prevent olf-setting, means for drawing the web from the lowermost fold of the loose pile and placing said web under tension,

means for trimming the web after it has been placed under the latter tension and mzans for spooling the web into a finished ro l.

2. In a web printing mechanism the com'- bination with a printing cylinder, of means for engaging opposite edges of the printed web for drawing it from the cylinder, means for loosely receivingthe printed web and arrangingy it in a series ofv superposed loose folds to retard its advance and allow the ink thereon to dry sufficiently to prevent off-setting, means for drawing the lweb from the lowermost fold in the receiving-means and placing the said web under tension, means for trimming the printed web while it is under tension and means for winding the trimmed web into a completed roll.
