PRINTING TY'IECHANISM.

Application filed October 16, 1911. Serial No. seams To all :whom it may concern Be it known that 1, WILLIAM R. ALLEN, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Printing Mechanisms, of which the following is a full, clear, and exact description, reference being bad. to the accompanying drawings.

This invention relates generically to rotary printing devices, one object being to provide for an effective automatic inking of the rotary printing form. This I accomplish by automatically causing the form cylinder to engage at one time the ink device and at another time the platen roller, and I provide a suitable movable guard to prevent the form cylinder, when not impressing, from inadvertently smudging the paper traveling between the form. cylinder in conjunction with another printing mechanism to produce therewith properly registering impressions on the same sheet. When the present mechanism is so correlated I provide (in addition to the means forinking the form and therneans for guarding the sheet) means for regulating the position of the impression made by the present print ing device out of action, when desired; and means for giving the proper adjustments to the various parts. These features, as well as the generic characteristics, are all coinprehended within my invention.

An approved embodiment of my inven tion as a signature printing attachment for a press is illustrated in the drawings hereof and is hereinafter more fully described, and serves as an illustration of the various char acteristics of the invention. These characteristics are summarized in the claims.

In the drawings, Figure 1 is a side elevation of my signature printing device at? tached to and cooperating with a rotary printer similar to the multigraph; Fig. 2 s

As shown in Fig. 1, 10 represents one of the vertical end plates of an office printing press, similar to the niultigraph, and having a rotary printing drum 11 carrying the form and a rotary platen 12 cooperating therewith. A suitable crank 13 connected with the drum is shown as providing means for rotating it. On the drum is a gear it which meshes with a gear 15 connected with the platen.

Fig. t shows the drum 11 as provided with a series of parallel overhanging longitudinal rails 16 which are adapted to loosely carry l:.etween them parallel rows of individual type grooved on their opposite sides. This much of the construction is the usual one in the printing portion of the multigraph.

In such machine as described the paper is fed from the front or from the left, in Fig. 1, between the drum and platen, by a suitable feeding device not shown, and the print ed sheet passes to the rear along a horizontal frame plate 17 for delivery.

In the present invention 1 mount at the rear of the printing machine the signature printing device in position to cooperate with the delivery rolls and arranged to receive and act on the sheet passing rearwardly and horizontally from the printing drum and platen. That construction will now be described.

Suitably secured to the frame of the print- 111g machine is a horizontal cross plate 20 which formsthe base of the signature at- I tion of the plates at, which are secured to the frame of the multigraph. shown,

the'plates 24; are secured toa fiange18 of the base portion of that frame by screws 25, Fig. 1. The flanges 21 are secured to the plates 24 by. screws 26. Secured to the upper pair of vertical.

end plates

28 and 29, which carry the various parts of the signature printer. These end. plates, together with the plate 20, constitute, in effect, the frame of the signature printer.

Extending horizontally and journaled in the

plates

28 and 29 is thorns-iiishaft 30 of the signature printing device; This shaft is journaled at its ends on-

short studs

31 and 32 clamped in the vertical, plates by set screws,.indicated by 33, Fig. 1. These studs have 'pinson their ends extending into sockets in the ends of the shaft. Loosely surrounding the shaft '30 in an'eccentric sleeve 35 and journaled on this sleeve is the signature'roller or form cylinder 36. The form roller 36 carries a suitable electrotype or other printing form, shown in Figs. 2 and 3 at t0- This curved ele ctrotype is shown as mounted on the periphery of the to be accommodatel.

roller 36 and held its edges by overhanging clamping pic. 41. Several of these clamps are shown as ilcttedand they are secrew crewing into radial holes in the roller. Z. re are preferably a number of such holcsin the wall of the roller to -enable various sized plates The interior ofthe roller is recessed at to form an oil receptacle, lined with a felt sleeve 38'to prevent escape of oil through the holesin the roller. Radial oil openings are provided on the eccentric 36 which may be fed through radial 0 enine's the roller normall lu ed b v p e: tat:

screws 39, Fig. 7.

The roller 36 is rotated by the-shaft 30 irrespective of the position of the eccentric sleeve 35 within the roller by a shiftable coupling, which is shown in Figs. 2, 5 and 7.

- .Th'at coupling consists of three parts,

46 and on the other side, at right angles to namely,'a head 4,5 rigid on the shaft 30 and having a pair jof diamentrically opposite grooves l6; a bossl8 on the end of the roller 36 having a pair of diametrically opposite grooves i9 at right angles to the grooves l6; and an intermediate ring 50 having on one side a pair of ribs 51 occupying the grooves the ribs 51, a pair of ribs 52 seating in the grooves l9. The-securement of the head to the shaft 30 may be'co'nveniently accomplished by providing this head with a. hub

face of the plate 20 by screws 27 are a v adjusting the approach 53 and having a pin 5% pass through'such hub and through the shaft.

lVith the construction described, the head 4-5 must rotate with the shaft and the rin must rotate with the headbut can shit thereon diametrically, and theform roller 36 must rotate with the ring but may shift thereon diametrically at right angles to the shifting of the-ring. This double shifting allows the roller to shift in any directionwith reference to the headwhile it must-'rotate therewith. This shifting ofthe nbller is provided bythe turning of the eccentric, and operates to carry the signature roller,

alternately into contact with the inking 30 roller and into contact with the platen;

This operation will be described presently.

Above the signature roller is an inking roller (30 coa cting With another roller 61. The roller is preferably of rubber. and the roller 61 of felt, so that the roller 61 may conveniently'be a fountain roller and the roller 60 a distributer therefrom to the form. Mounted below'the signature roller is-the platen roller 63- It will'be seen from Fig. 3 the signature roller cannot contact at the same time with'both the roller 60 and the roller 63-, but the shifting of the eccentrio 35 may bring it into cooperation with either roller, so that the type form 40 may be inked by contact with the roller 60 and then by the depression of the form roller 'niay cooperate with the platen roller 63.

Fig. 3 shows the parts in position for the form e0 to engage the ink roller.

The'platen 63 is shown as consisting of an elastic sleeve of rubber'on a shaft 65. This .shaft is journal ed at its ends on pins (see Fig. 1) projecting eccentricall-y from a pair of studs 66 and 67, these studsbcing mountclamped by set screws 38. and 69. The loosening of these set screws allows the knurled heads on the studs to turn them to change the position of the shaft 65, thus of the platen to the form roller and regulating the-impression.

The two inking rollers are mounted in a yoke-like frame consisting of a' cross bar 70 which has downwardly extending end 29 by studs 73 and7l. A plate 75 pivoted concentrically of the studs 73 forms in opthe inking rollers, I make the yoke 7 0 sepavrable from the extension 75. This I accom- 4 plish by making th s extension in the form "139 ed in. the

end members

28 and 29 and 11G plates 71 and 7 2 pivoted to the plates 28 and i amount of ink.

of the flat bell crank shown, with a stud 79 which is adapted to occupy a notch in the rear edge of the yoke, and I make the pivot studs 73 and 7f removable and lock them by set screws. The removal of these set screws allows the studs 73 and 74: to be drawn out,

thereby freeing the connection between the yoke and the plate 75 and allowing the yoke and its rollers to be removed intact.

The fountain roller 61 is loosely mounted on a shaft between a pair of ears 81 and 87 on the yoke 70. This shaft has an eccentric extension 82 ournaled in the ear S1 and another eccentric portion 83 journaled in the end plate 72 of the yoke, and intermediately passes through an enlarged opening in the ear S7. The outer end of the shaft 80 is provided with a knurled head Set by which it may be rotated, and it is locked in adjusted position by a set screw This arrangement enables the fountain roller to bear on the transfer roller with proper adjusted pressure to transfer the proper Moreover the loosening of the set screw 85 allows the shaft to be drawn out and theroller 61 removed entirely for cleaning or replacment. This enables the ink to be changed Whenever desired.

The transfer roller 60 is mounted on a shaft 86 which is journaled at its ends by means of short studs carried by the end plates 71 and 72 of the yoke. A stud mounted in the end 71 is shown in Figs. 1 and 2 as provided with a knurled head 88 and as clamped by a set screw 89. The pin in the end of this stud occupies a socket in the. shaft 86 corresponding to the engagement of the stud 31 with the shaft 30 shownin Fig. "I. The stud carrying the otherend of the shaft 86 is similar, except that the pin is eccentric of the stud after the manner of the pin on the platen studs 66 and 67. This enables adjustment of the shaft 86 to preserve proper alinement with the type form.

From the construction described it will be seen that the fountain roller may be adjusted toward and from the distributing roller, the distributing roller adjusted into proper alinement with reference to the fountain roller,'and the whole frame carrying both the fountain roller and distributing roller adjusted about an axis to cause the distributing roller to bear on the form with the proper force when the form is raised to receive the ink.

To enable the desired shifting of the form roller back and forth between 'the platen roller and the distributing roller, I provide the following mechanism: Mounted on the shaft 30 is a pinion 90, Fig. 7, which meshes with a gear 91 journaled in a stud 97 mounted in the frame plate 29. In the embodiment shown, the diameter of the gear '91is four times the diameter of the pinion 90. Formed by ribs 93 and 94 on the side of this gear is a peculiar internal and external cam. The internal face of this cam, provided by the concave edge of the rib is indicated by 92. This concave edge is concentric for something over a quarter of a circumference and then flares outwardly until it merges with the outside surface of the rib 93. This takes up somewhat more than half of the circumference. On the opposite side of the axis from the rib 93 is the rib 9%, the convex outer surface of which constitutes a concentric cam. This surface is preferably somewhat less than a quadrant in length and is spaced at each end from the points of the rib 93. A pawl 95 is pivoted at one end of the rib 9=1 and bears at its nose against the hub 98 by which the gear is journaled. A spring 96 seated in a recess on the face of the gear holds the pawl in normal position.

Pivoted to the frame by a stud 100 is a lever 101 carrying a roller 102 adapted to coact with the cam. The lower end of this lever is connected by a pin and slot with a plunger 103 which extends into a socket in the base frame and has a head 10% bearing against a spring 105 in the base of the socket. Surrounding the shank of the rod' 103 in front of the head is a spring 106. This spring is compressed between the head and a bushing 107 screwing into thebase frame. Accordingly, the two springs tend to center the lever but allow it to swing in either direction. The upper end of the lever is connected by a link 110 with the plate 111, which isrigidly connected to the end of the eccentric sleeve As shown, the plate surrounds projecting end of the eccentric sleeve and is prevented from rotating independently of the sleeve by a locking pin 112. This plate is connected to the lever 110 by a stud 11 3 extending from the plate.

Now, with the construction described, when the shaft 30 is rotated, the gear 91 is correspondingly rotated in the right hand direction (Figs. 3 and 9) at OI1-fuui th specd and the rollcr102 travels in the tcrnal cam groove between the hub 98 and the surface 92 and then outwardly along the convex face of the pawl 95, beyond the surface 92 and around the outer face of the rib 9i and then it passes off of the ribflt and the compressed spring 105 forces it inwardly into coaction with the internal cam.

Now, when the roller 102 is on the inside cam 92, as shown in Fig. 3, the eccentric holds the signature roller elevated so that the plate -10 thereon may contact with the inking roller 60 to obtain ink. This position of the signature roller is maintained for two of its rotations, or for substantially a half rotation of the gear 91. Then, as the roller 102 passes out of the inside cam, the

rocking of the eccentric caused thereby depresses the signature roller into coaction with the platen roller. This movement takes about one-eighth'rotation' of the gear .91 'or about one-half rotation of the signature roller. Then the roller 1022 comes onto the external surface of the rib 9i and the roller 102 passes-inwardly through the opening between the ribs into the internal groove, ready for a repetition of the operation.

Inthe operation above described, the double acting spring 105, 107 allows the roller to operate on the insideand outside cam surfaces-and keeps it iii-proper contact with each surface, as required. The pawl 95 sets as a stationary surface during proper rotation of the parts,,but if they be rotated -.in. a backward direction for any reason, the

roller, on striking the concave face of the pawl, simply shoves it idly away and continues its position, so that the signature 1- .provide aiguar'd plate Fig. 3.

roller is not shifted. The two rotations of the signature roller past the distributing roller insure proper and eflective inking of 'the type form on the signature rollerx To prevent the sheet of paper from being in. vertently inked as t passes betweenv the separated form cylinder and platen roller, normally standing beneath the formcylinder and above the platen, the paper passi: beneath the guard.

When the form cylinder is lowered this guard 1S automatically swung to inactive position.

As shown, the guard is a curved plate designated 120. At one end it is-secured to a'collar 124;, which is loosely journaled on the hub '53 of the coupling head 45. This collar being hollow also serves the purpose of covering the coupling between the shaft and signature roller. At the other end the guardis provided with ears 121 and 122 (Fig. 6) secured to the plate 111 by which the eccentric sleeve is rocked. The guard-being thus rigidly connectedwith the eccentrio sleeve 35 on the side of the axis opposite the greatest eccentricity, it follows that whenever the eccentric isturned to lower the form roller into active position the guard is'thereby swung upwardly out of'the way. When the eccentric is turned in the other direction to raise the form roller, the guard is returned to normal position, as shown in The powerfor driving the various rollers is preferably lfl of the printing drum with which the signature device cooperates. As shownin-Fi'gs.

change the relation t obtained from the main gear.

-shown as journaled on a. stud 137 held in the frame plate 28 by a set screw 138. The portion of this stud beyond i frame plate forms the hearing for the he 75, and the stud has a socket in outer end to receive the stud "Z3 pivoting the yoke carrying the ink rollers. The idler 133 meshes with another idler 134: which meshes-with a gear 135 c on the shaft 86 of the distributing roller.

The fountain'roller is rotated by its frictional contact with the distributing roller. As heretofore explained, theshaft 30 is a pinion 90 meshing with the gear 91 on the cam.

to roll in the pr zper d the gearing described men to advance the sheet prints-1 and discharging rearwardly by the m n drum and platen of the multigraph.v '11 i-gearing to the cam 91 causes the periodic transportation of the signature roller from the inking device to its own ent is in prearranged "he inting drum. rollers rotates to the nil l'l go 0 into w ich they may adjusted o adjust impression on the sheet with reference to the printing driun, it is simply necessary to he gearing between the drum and .ithei' gear 131 of the attachment.. I provide for this by making the idler 130 shiftable out of mesh with the gear 131 or the gear 14:. I prefer to disconnect it from the gear 131. accomplishthe disconnection mentioned by mounting this idler rotatably and slidably on a short stud 140 which is rigidly mounted in an ear on the frame plate 10. Slidably mounted in this ear plunger 142 which carries a yoke 1&1 occupying a. peripheral groove inthe hub or idler. Aspring 144 surrounding this plunger 14:2 tends to keep the parts in engagement. Whenever it is de-,

sired to change the adjustment this plunger is forced inwardly hy-the operator pressing on its head 145, thus disconnecting the idler from one of its gearsg iihen the printing 'druinis rotated in one direction or. the other a proper distance and thesidler returned into mesh so as to properly correlate the signature printer with the main drum. The main gear 1 1 is naturally of-greater width than the gear 131, so that the inward movement of the plunger 14:2maydisconnect the idler 130 from the gear 131' while leaving it eonl and platen roller 1 roperly, irrespective of the actual pothe position of the signature As shown, 1 Y

nected with the gear 14. This adjustable idler and its operating plunger enable the signature printer to be quicklyand accurately set with reference to the matter on the drum so that the signature may be printed in exactly the proper place on the sheet. If a finer adjustment is desired than that prpvided by a change of one tooth in the gear, it may be accomplished by shifting 0 the printing plate 40 on the signature roller,

though in ordinary operation such finer adjustment is unnecessary.

The product of the main printing drum and platen is delivered between the signature roller and its platen. To assist in this delivery. I mount delivery rolls on the shafts 30 and These rolls are best shown in Fig. 2. They are designated 150, 151, 152

and 153. The rolls lEiQ and 153 are preferably immovable and keyed to their respecin their respective shafts.

paper between the shield 120 and the platen 63, this could be accomplished by simply removing the printing plate 10 from the printing roller. However, to enable the signature printer to be idle without requiring the removal of the plate, I provide a special throw-out device. This consists of adjustable means carrying the roller 102 and serving to withdraw it, when desired, from the range of the cams on the gear 91. As shown,

49 the roller 102 is mounted on a plunger 160 however, may be having a head 161 slidably mounted in a.

boss 163 on the lever 101. A spring 161 tends to maintain this pin in its innermost position with the roller active. The pin, ulled lengthwise by means of the knurled head 161 to withdraw the roller outiof range with the cam and hence to inactive position, and the parts may be maintained in this position by then 50 turning the head, which causes a pin 165 imprint.

carried thereby (normally occupying an opening in the barrel 163) to stand on the ,end of the barrel and hold the parts in inactive position. Accordingly. whenever it is desired to throw out the signature printer, it is simply necessary to take hold of the head 161 and draw it to the left in Fig. 2 and give a slight turn. when this is done the signature roller is maintained m idle position. The guard 120 then continues to occupy its normal position and the sheet printed by the main drum and platen is delivered between'the guard and platen 63 by the delivery rollers without a signature To insure against the printed sheet clinging in any case to the signature roller. or accidentally coming in contact with the fountain roller, I provide a stationary protecting rod 170 at the rear of the signature roll-3r and extending lengthwise or the attachment. This rod is shown as mounted at one end in a socket in the stud 9'7 and at the other in the frame plate 28, where it is held by the set screw 171. If desired, this rod may carry some suitable guide or receiving device for the printed sheets.
