Application filed November 17.y 1905. Serial No. 282,563.

Be it known that l, lllnmnn Seor'r, a citizen of the United States of America, and a resident oir' Plainfield, Union county, New Jersey, have invented certain new and useful improvements in lilulticouple Multirevolotion ljrinting-liiacliines, of which the 'following is specification.

The present invention relates generally to printing machines, and has more particularly reference to the arrangement and construction of the. parts of a multi-couple multi-revolution m: chine, and to tripping mechanism connected therewith.

in the prior art. of multi-revolution ina-- chines, it has been customary to provide means for automatically tripping and untripping the impression at regular filerrals ence to a certain number or" revolutions or once to each cycle o t' the printing eouple. lrieans have further been provided 'for pre- Ventingl the ferm and impression .members composing the printing couple from returning;` into contact by reniglering the automatic means aforesaid inol'ierative or incapable of acting to bring the separated members into Contact.

The automatic meanslwliich act at regular intervals to lrip and untrip the impression are for the purpose of preventingr the form iii-ein placing the ink on the packing of ythe impression cylinder during that revolution et' the impression cylinder when there is no Sheet to receive the impression, and to bring ille form and impression members properly into Contact When an impression is to take place. It sometimes happens, however, that a sheet is missed in feeding, and to prevent the form from coming in Contact ivi/ih the impression 'cylinder during its first revolution, the means, ilor renderingl the antomatic means aforesaid incapable of returning the members oil the printing couple into Contact, are provided. Likewise, when a sheet is not fed properly and the .impression would be placed out of register with the sheet, it is desirable to prevent the .impression and thus save the sheen 'which would otherwise be spoiled. Again, when inlring up tlie form, it is of course necessary to run the machine with 'the impression tripped.

The aforesaid 1r. Ains for rendering the autoniaticnneans inoperative generally under the control/oi the operator,y but in case automatic feeders are user, it. is enstoniary to connect up the tripping' mechanism and feeding machine either mechanically as by springs or Weights, or electrically. This is so vieil understood in the art, that ne need exists for going` into details relative thereto.

ln the art relatingl to mulli-:evolution machines, especially of a rotary nature, there has been derelopcd a type oi machine in which a plurality ot printing couples are employed to. print en the same side or' the sheet for multi-color work or the like. Gbyiously. this advance in the art makes it desirable to produce a nmehine in which the impression of the several couples is tripped and uutripped autonialiealljf ond periodically at regular intervals, coijnbincd 'with means` set in motion by an actuating de-.

rice under the control of the operator or of an automatic feeding` machine, for preventing the automatic means from bringing the members oil the several couples into printing Contact. These meansl should act sequentially upon the several prinling couples, so that he'seeond printing couple will not be held out of impression until the sheet, properly printed by the .iirst couple, has been printed on the second couple, and so on, and whereby also when the automatic means regain control or" the machine, the members on the said second printing' couple will not be brought into Contact until the sheet printed properly by the first printing couple is received by the impression cylinder of the said second printing;- couple. i

The main objecfr or the present invention is therefore to produce a plurality of printingl couples adapted toprint on the saine side of the sheet, in combination with means for automatically end periodically, at regular intervals, tripiiiing and untripping the impression of the members composing the several' couples, 'together with means, under the cont-rol of the operator or of the automatic feeder, for maintaining the members in their separated position, the said means being operable from a single actuating cle-4 vice to communicate the motion to the mem bers of all the couples .in regular sequence, and whereby when the said actuating dc vice is released, the machine will` resume its former operation and be tripped and nntripped again automatically at regular intervals.

The form and impression members comprising the printing couple will preferably be of the rotary type and are so shown in the drawings forming a part of this specification, though I do not wish to limit myself for all purposes to a ons'truction involving rotary printing couples." i

Another object resides in including th above-mentioned printing couples and tripping mechanism in a unitary structure.

Still another object resides in providing sheet conveying means such as transfer cylinders, between the successive impression cylinders which are capable of receiving and transmitting the sheets to and from the several impression cylinders whether the latterare in or out of contact with the form members. Y

It consists further, in a new and improved arrangement of sheet carrying devices on the .impression and 4transfer' cylinders, whereby the said sheet carrying devices, such as grippers, are operated in harmony with the rotation ofthe several cylinders and are capable of seizing and releasing the sheets whether or not the impression is tri ped.

' ther objects and features of construction will appear as the specification proceeds.

,.The `mvention is embodied ina 4Jconcrete structure in the accompanying drawings, in which is shown the preferred form; the in* vention, however, is susceptible of wide modifications without departing from the true spirit and scope thereof.

In the said drawings: Figure l is a side elevationv of so much of a printing'machine as is necessary to properly .illustrate my invention. Fig. l is a. detail view showing a part-'of the feed board and the gages used in connection therewith. Fig. 2 is a hori zontal transverse sectional plan view on the line 2-2 of Fig. l. Fig. 3 is a view partly in section, on the line 3MB of Fig. 2, looking-in the .direction of the arrow. Fig. 4 is a `det-ail view, partly in section, and with parts removed looking in the direction of the arrow 4 in Fig. 3.

Similar characters of reference indicate corresponding parts inthe several views.

y 1 indicates a framework of anyV suitable construction. for properly supporting the parts lcomprismg the' machine. In this framework are mounted a lurality of print mg couples, preferably oa rotary nature, there being 1nv the present instance three such couples, arranged substantially one above the other. Each couple consists of a l form and impression meml'ier, and is adapted to make a nui'nbcr of rcvdvtions to each i1n pression. ln the present istancc.y the cylinders revolve twice to cach impression.

2 is the impression cylinderl and 2i the form cylinder of the first printing couple,

' while #lis the impression cylinder and 5 the form cylinder of the second ,printing couple, and G is the iminession cy'indeivand 7 the form cylinder of the third print-unf; couple. The impression and form cylinders are preferably of equal diameter, as are the .transfer cylinders S, 9 and 1 0, which are interposed respectively between the irst and second impression cylimler, between the second and third impr ion cylinder, and between the third impr( on cylinder and a suitable delivery mechanism (not shown). This last mentioned cylinder l() may be a collecting cylinder, if desired. All of the impression and transfer cylinders, except the first impression cylinder, are provided with grippers closed by signings in the usual way, and opened by means 'of cams. The irst impression cylinder, however. is provided with tumbling grippers which are caused to tumble back and `forth nearly onehalf of a. revolution by suitable means which will be more fully hereinafter described. ln multi-couple multi.l'evolution machines, this construction in which the firstimpression cylindcr is provided with tumbling grip pers is advantageous for the reason that the l sheet must be positively seized and that the feed board might interfere with the operation of spring seated gri Viper@ which have to be raised above the sur ace of the cylinder when the feeding point is reached. lt is furtherniore advantageous in this type of lmachine that the first innaressimi cylinder should print and deliver the sheet during its first revolution, remaining idle during its second or further revolutions, otherwise the sheet would have to be carried a second or third time past the feeding point. The other impression i. ',lindcis, however, are so arranged .with relation to their respective form and transfer cylinders, thatv the impression taltes place during their first revo` lution while the sheet is delivered during a portion of the second revolution of the cylinders.

11 is the feed board, adjacent to which are gages 12, against Wlnch the sheets are fed, and which are raised in a well known manner when the grippers on the cylinder 2 seize a sheet.

l taking another sheet.

' grippers similar to 34 During makes ing this, but

The cylinder Q is provided with the grippers 19 which are arranged to tumble back- "ard and foi-Yard nearly half a revolution hy means of a crosshcad Q0 mounted on the gripper shaft Q1. Suitable means are provided for closing' and opening the grippers once to a number of revolutions of the cylinder, and duringv the first revolution of the cylinder only. These meansl` in the present instance, take the iorm ot two rotatinpT earns 22 and 23, which are driven so as to rotate once to a number of revolutions o the inipression cylinder hy means of the pinion Qi and gear 5 (the relation being one to two)r` and suitable conm-(lions as the levers 2G and 2T, operated by theI said cams so that the pins 2S carried by the said levers will project into the planel of the rotating crosshead 'of the cylinder, the lever Q6 acting to close the grippers, and the lever /T to open the gripiiers, The. parts are so arranged that as the grippers come to the feeding point the lever 26 will canse the gripii-ers to hc closed as to seize a sheet, which latter 'then receives an impression when it reaches the form cylinder the saine revolution, and when the grippers reach the axial line between the cylinders Q and S, the grippers are opened by the lever 27j ,vlierehy the sheet is released and taken on the transfer cylinder' 8. The cylinder 2 then completes its revolution, and another revolution, with the grippcrs in their open position, running idly Without, The grippers on the other impression cylinders are closed by springs in the usual Way, and opened by cams to rece-ive a sheet during one revolntion, and opened to deliver thc sheet din-ingr another (the succeeding) revolntii'in. The transfer cylinders 8 and 9 are provided with the ones on the inipression cylinders l and G. however, are opened and closed twice daring` the first revolution7 and are preferably idle during the second revolution. Any suitable means may of course be ei'nployed for cifectpreferably l employ rocking cams which` are adapted to be moved into the plane or path. of the usual rollers on cranks (or any other means) carried by the gripper shaft-s, at predetermined intervals. The preferred construction of these parts is as follows: The rst transfer cylinder 8 provided With the spring-seated grippers 23) connected to which is the roll 3() adapted to be acted upon during` the l'irst revolution ot' the cylinder by the cam 3l. This cani is shown in the presentinstancc as a stationary cani for the reason that there is no sheet. on

the first impression cylinder during the Second revolution and it is therefore not necessary to move this cam ont oi" the plane of the gripper mechanism duringy the second revolution. This cani will therefore also open the grippcrs dnrlng the scwnd revolumanges These grippers' tion, but there being no sheet on the firsty impression cylinder, no result will follow. The cam 32, however, which acts to open the grippers to deliver the sheet to the second impression cylinder is moved into the plane of the. gripper mechanism during the first revolution, and ont or" the plane of the gripper nihanisin during` the second revolution, so that the said `rippers will not pierce the sheet on the second impression cylinder which is carried pas the axial line between the first transfer cylinder and second impression cylinder and delivered duringa the second revolution of the said second impression cylinder. To this cend the cam is mounted on the rockingl lever pivoted at 3l and haring a roll Blu at its outer end engaging with the cani This cani 35 is mountedon the shaft 36 conveniently driven from the shaft 37v of the second impression cylinder by instance, one revolution to every two revolutions of the printing and transfer cylinders This cani sha'lt also controls the, cam l() mounted. on the lever 4l pivoled at and having 'the Jfriction roll at its outer end, which engages the earn '1M mounted on the said cani shaft. This cam il is adapted to he moved into the plane or" the spring gripper .mechanism Ll on the second inipressioi-i cylinder during' its first revolution soas to open the grippers to receive the sheet' and siilistantially at the saine moment .the grippcrmechanisin on the first transfer cylinder isA opened to deliver the sheet.

suitable guide G5 interposed between the Said,

impression vand transit' i' cylinders, so 'that the sheet may be carried on to be delivered with its printed side out. lt obvious, fur-- ther, that the transfer cylinder l0 may be a collecting cylinder, and :trom this transfer cylinder the sheet 'may be delivered in any suitable way as by a drop delivery or otherwise. This is folly disclosed in an applicau tion `filed by me on the lith day oi August, 1902, Ser. No. 119,212, and it is therefore thought unnecessary to enter into the details ot' this part oi' the machine in the present application.

The third impression cylinder is provided with a spring-seated gripper mechanism titi and with throw-oil lingers G7 of a well known construction. i livery point ot this c vliiufler is but a. short distance away lroin the receiving point or troni the axial line between the secoiid trans fer cylinder and the third impression cylinder, only one cam is necessary in this instance,.to open the gripper mecl'ianism on this third impression cylinder. This cam which is designated by the numeral G8, is adapted to open the'gripper mechanism duringI the first revolution of the cylinder to rcceive a sheet and again to open the gripper mechanism during its second revolution to deliver the sheet, the said cam being moved into dili'erent positions to effect this opera tion. ln other words, the cam is in the plane of the gripper mechanism duringl every revolution ot' the cylinder, but opens the gripper-s at a different point oi the rol ation ot the cylinder. The precise means for carryingl ont this, may ot course loe varied, but preferably this cam is caused to oscillate around the shaft oit' the cylinder by being provided with a sleeve 69 Which at its outer end is provided with a gear segment 70 adapted to be operated by any suitable means to shift the cam back and forth a certain distance from the receiving point to the delivery pointof the cylinder. Preferably this cam is alsg.` operated from the rotating -caxn 5G by means of the `gear sector 71 pivV oted at 72 and provided with an arm 73 have ingl a. friction roll 74 which engages with the said cam 5G. it will thus be seen that the cam 5(3 controls the gripper cams on the second transfer cylinder and third iinlpres# inasmuch asthe deloro; e

sion cylinder as ivell as one oit the cams of the second impression c "ndeix lach ol the three impression cylinders is inrninted in an eccentric hnsl'iinr T5 upon its shaft, whereby when the said eccentric hushings are turned, the' impression cylinders Ywill be moved in and out of printing contact Awith the plate cylinders. The distance which it necessary to raise these impression cyl inders in order to properly trip the saine, is only about threc-sixteenths of an inch, so that the gears on the respective cylinders are never ont oil: mesh with eachA other. This tripping of the impression cylinders does not allect their relation. to the transfer cyl inders, for theslieet is always capable of being passed through the machine whether or not the impression is tripped. The said eccentric bushings 75 are connected by nieans oii the short arms 76, connecting rod 77, and levers 78, to the rockshatts 79, and 8l, there being; provided one rockshaft tor each impression cylinder. Suitable means are provided 'for rocking these rocksliafts at regular intervals so as to automatically trip and untrip the iniinfcssion cylinlers at predetermined intervals once to each cycle ol' the machine. In the present instance, the irriprcssion cylinders are tripped daring,l Vtheir second, revolution of each cycle ot the machine. Obviously, the means for accon'nrnlishing,` this may bc varied Widely, ont preferably there is mounted upon the cam shaft 18 three cams 82, 83 and 84.-,whicli, as previously explained, are given one revolution to a nuniber of revolutions (in the present instance to every two revolutions) of the machine.

a shaft extending transversely of the machine and on which are loosely mounted a plurality of arms (in the present instance three), one for each impression cylinder, numbered respectively 8G, 87 and 88. Each of the said arms is provided with a roller 89, which engages in its respective earn groove on one of the cai'ns 82, 83 and 84.

Suitable means are provided for communicating the motion of the arms 8G, 87 and 88 to the roclishalits T9, 80 and 81. In the present instance, these means take the form of slotted connections 90, 91 and 92, connected, by means of the levers 93, to the rockshafts aforesaid, and receiving the motion of the arms aforesaid by means of pins 94 carried at thelower ends of the said arms, and adapted to play in the slots 95 of the connections aforesaid and to be locked with the said connections When the pins 94 are in the recess 5 )6 'of the said slot-s. From this'it will be understood that'during the normal operation of the machine, the cams 82, 88 and 84, by their rotation, Will cause the arms 8G, 87 and 88 to oscillate, thereby moving the slotted connect-ions aforesaid and rocking the rocltshaits.

In this manner Iit will be 'understood that although the automatic latch mechanisms will be automatically released once to each cycle of the machine, they will have no effect upon the cams 98 and 99, because the slotted connections are kept in their raised position,l and# the'springs 118 .and 127 are thereforeprvented from returning to their expanded position. I'Vhen the foot treadle is now released lor unlocked, the counterf Weight 132 Will moveL the lever 107 outward and the spring 110 will move the member 105 outward, also, thereby positively sliding the cam 97 out of the plane of the in 102 by reason of the forked connectionl which rests in the circumferential groove 133 of the bushing of the said cam 97. The autormatic tripping and untripping' means now regaining control .of the first printing cou ple, will, in turn, act to release the latch mechanism of the second printing couple,l and that in turn will release the latch mechanism for the third sprinting couple, and thus the machine will be restored to its normal function again.
