- Fig. 3 is a rear elevation
- Fig. 4 is a vertical sectional view taken sub- 15 stantially on the line 4-4 on Fig. 3.
- 5 indicates' the printing cylinder and 6 the platen cylinder of my novel printing couple.
- An electroplate or 20 other printing form may be retained on the printing cylinder 5 in the manner shown in the Kranz Patent 1,955,814, patented April 24, 1934, or in any other suitable way, and ink may be supplied to this printing form in the manner shown in 26 Kranz Patent 1,946,217, patented February 6, 1934, although it is to be understood that other suitable ink supplying means may be provided without departing from the purview of my invention.
- the platen cylinder 6 is preferably equipped with a tensionable blanket in the manner shown in the ⁇ Kranz Patent 1,937,119, patented November 28, 1933, although 35 it is to be understood that the platen cylinder 6 may be equipped with a blanket or equivalent means in any desired way without departing from the purview of my invention as long as uniform impressions from the printing form on the print- 40 ing cylinder 5 are insured.
- the printing cylinder 5 is fast on a shaft 'l journaled in a sleeve 8 of the frame 9 for the printing couple.
- the platen cylinder 6 is mounted on the eccentric part I0 of a shaft II which in- 45 cludes concentric bearings I2 and I3.
- the bear.- ing I3 is journaled in a bushing I4 (Fig. 4) secured in one end of a strap I5 and a suitable journal: is also provided for the outer free end of the shaft 'I in this strap I5.
- a brace I6 (Fig. ⁇ 2) 50 is secured to the strap I5 at the end thereof in which the bushing I4 is secured and this brace is rigidly connected to the frame 9.
- the brace IB and strap I5 aord an overhanging bearing structure for the louter free ends of the shafts 1 55 and II and increase the rigidity of the printing couple.
- a gear I1 is fast on the shaft 1 and meshes with a pinion I8 fast on the shaft I9 journaled in the frame 9 and having a pulley 20 thereon about which a belt 2
- a suitable source of power such as an electric motor (not shown) whereby power is supplied to the shaft I8 to rotate the pinion I8 and the gear I1 and therefore the shaft 1.
- a gear 22 is fast to the cylinder 5 as, for example, in the manner illustrated in Fig. 4, and meshes with a gear 23 rotatably mounted on the bearing I2 of the shaft II, said bearing I2 being journaled in the frame 9.
- a pair of lugs 24 and 25 is provided on the side of the gear 23 facing the cylinder 6 and a stud 26 on this cylinder fits between these lugs.
- the gears 22 and 23 are of an equal size and have a corresponding number of teeth and therefore when the shaft 1 is rotated and as the cylinder 5 rotates therewith this movement is transmitted from the gear 22 to the gear 23 to the stud 26 and cylinder 6 wherefore the cylinders 5 and 6, which are of equal size, are operated synchronously.
- a vertical shaft 28 is journaled in the frame 8 and has a bevel gear 29 fast thereon which meshes with a bevel gear 30 fast on the shaft 1.
- is fast on the shaft 28 and meshes with a bevel gear 32 fast on the shaft 33 suitably journaled in the frame 9 and which may be extended into a machine with which the printing couple of this invention is associated to drive operative parts in such machine if so desired.
- and 32 is preferably one-to-one and it will therefore be seen that the shaft 33 operates in timed relation with the shaft 1 and therefore the cylinders 5 and 6.
- 'Ihe stop finger 21 is fast on a shaft 34 journaled in bosses 35 (Fig. 2).
- An arm 36 is also fast on this shaft and provides an abutment engageable by an adjustable pin 31 mounted in a rocker 38 pivotally mounted on a shaft 39 suitably journaled in the frame 8.
- An arm 48 (Fig. 2) on the rocker 38 carries a roller 4I engageable with a peripheral cam 42 fast on the shaft 33.
- a stud 43 (Fig. 1) is fast in the rocker 38 and one end of a spring 44 is fast thereto and the other end of' this spring is connected to a spring anchor 45 fast in the frame 8. The spring 44 so acts on the rocker 38- that the roller 4I is urged into engagement with the peripheral cam 42.
- Configuration of the .peripheral cam 42 issuch that at a predetermined time in the operation of the printing couple a relieved part on the cam moves into engagement with the roller 4I whereupon the rocker 38 is moved by the spring 44 and the adjustable pin 31 engages the arm 36 and pivots the shaft 34 to elevate the stop finger 21 out of stopping position into the position shown in Fig. 1, whereupon the sheet S which has been engaged therewith is moved into the bight between the cylinders v5 and 6 to have an impression made thereon.
- suitable feeding means comprising the .rollers 46 and 41.
- the roller 41 is mounted on a shaft 48 and a part of the periphery thereof extends through an opening in the sheet guideway G.
- Theoller 46 is mounted on a shaft 49 journaled in the rocker 3B and, when the rocker 38 moves under the action of the spring 44 to elevate the stop finger 21, the roller 46 is lowered to thereby clamp the sheet therebelow in engagee ment with th roating roller 41 whereupon the sheet is fed into the bight between the cylinders 5 and 6.
- the shaft 48 on which the roller 41 is mounted has a gear 58 fast thereon which meshes with a pinion 5I carried by the stud shaft 52 journaled in the frame 9 and the pinion 5I meshes with the gear I1.
- the ratio between the gear I1, pinion 5I and gear 52 is such that the shaft 48 and therefore the roller 41 rotates rather rapidly and therefore a sheet clamped between the rollers 46 and 41 is rapidly fed into the bight between the cylinders 5 and 6.
- the pinion 5I is interposed between the gears I1 and 50 to rotate the roller 41 in a direction such that the sheet will be fed into the bight between the cylinders 5 and 6.
- roller 53 (Fig. 2) on shaft 54 of small motor 55 mounted on the side of the sheet guideway.
- 'I'his roller cooperates with the bottom of the sheet guideway to clamp the sheet and insures movement of the sheets into posi- ⁇ tion below the roller 46 and into engagement with stop finger 21.
- shaft 54 and roller 53 are inclined relative to the extent of the sheet guideway wherefore the sheets are forced against the side of the sheet guideway,
- roller 53 is sovpositioned that the sheet is out of engagement therewith when it engages the stop finger 21.
- the shaft II includes concentric bearings I2 and' I3 andan eccentric part I8 on which the cylinder 6 is mounted and this shaft II is arranged ior movement so that the most eccentric portion of the eccentric part I8 may be moved into and from a position wherein this most eccentric portion is'extended toward the cylinder 5.
- Such movement of the shaft II is effected by a peripheral cam 56 and a spring 51 in a manner now to be explained.
- An arm 58 is fast on bearing I2 and one end of a link 58 is pivotally connected thereto.
- the other end of the link 68 is pivotally connected to a rocker 60 and the opposite end of this rocker is pivotally mounted in a bifurcation in the block 6I as indicated at 62.
- an arm. 63 extends outwardly from the rocker 66 and carries a roller 64 that is urged against the peripheral cam 56 lby the spring 51.,r4
- the lobe on cam 56 is relatively short and hence a short time after the rocker '66 is pivoted upwardly the roller 6I moves off this lobe and the spring 51 therefore pivots the rocker 60 downwardly which shortens the toggle aorded by the link 59 and arm 58 and moves these parts into a position wherein the angle between the upper edges thereof is reduced.
- Such movement rotates the most eccentric portion of the eccentric part I0 away from the cylinder5 whereby the cylinder 6 no longer cooperates with thecylinder 5.
- the roller 64 moves from engagement with the lobecof cam 56 in this manner prior to the time the electroplate or other printing form on the cylinder 5 moves ,into
- Such means include the collar 65 fast on the bearing l2 between the arm 58 and the gear 23, as best shown in Fig. 4.
- This collarf has a notch 66 therein inwhich a stop lug 61 is .engageable
- This stop lug* is carried by a rocker 68 (Figs. 1 and 2) lpivotally vmounted on ⁇ the frame as indicated at 69.
- the rocker includes ay downwardly extending portion 1I) (Fig. 1-) that' extends below a lug 1l on arm-12A of rocker 12'that is'fast on theshaft39.
- a spring 13 is connected to the free end of the arm 121of the rocker 12 and the other end'of thisv spring' is suitably connected to the frame 9, and spring urges an'adjustablestop .14 mountedin therlug 1I toward 'the' downwardly extendingportion 16 .of the rocker '68.
- a roller is provided on the rocker 12 and this roller lis urged toward one side of cam v"56' bythe spring 13.
- a depression 1s is provided in this side f the cam 56 and atl a time in the y,operation ⁇ - after the rocker '60 has been pivoted upwardly the roller 15 moves into the depression 16'if a sheet has not been engaged with the stop finger 21 which, of course, means that no sheet is moving into the bight between the cylinders 5 and 6.
- the depression 16 is relatively short and shortly after the roller 15 moves thereinto the end of the-depression engages the roller 15 and pivots the rocker 12- so that the stop 14 is disengaged from the portion 10 vwhereupon the stop lug 61 moves into engagement with the periphery of disc 65.*At this time, however, the notch 66 will not be below the lug 61 but in the next operation Vwhen the rocker 60 pivots upwardly the notch 66 the roller 15 is prevented from passing down into the depression 16 and therefore the stop 14 does not engage the'portion 10 and the lug '61 remains in the notch 66.l Therefore, as long as sheets successively move into engagement with the-stop finger 21 the stop lug 61 will remain in the notch 66 and the cylinder 6 will be maintained in cooperating relation with the 4cylinder 5.
- the detecting finger 11 moves into the depression 19 (Fig. 2) in the bottom ⁇ of the printingdevice guidcway, andwhen this occurs the roller 15 may move into the depression 16 withthe effect above described, that is to say, movement of the cylinder 6 out of lcooperating relation with the cylinder 5.

Patented July l1, 1939 UNITED STATES PATENT oFElcE 2,165,535 PRINTING MACHINE Horace P. Brownsey, Cleveland, Ohio, assignor, by
mesne assignments, to Addressograph-Multigraph Corporation, Clevelandgohio, a corporation of Delaware This-invention relates to printing machines of the kind wherein utility bills, checks, insurance notices and the like are printed, and the primary object is to print constantly reoccurring matten, such as a form, on bills, checks, notices and the like during passage thereof through the machine.
Bills, checks, notices and the like are fed through printing machines of the kind to which this invention relates as parts of an elongatedweb or in the form of separate elongated strips which may either be cut from a web in the machine or which may be pre-cut and suitably stacked in the machine for passage therethrough. During passage through the machine the bills and the like usually have variable information printed thereon, such as an address or the like, from printing devices sequentially fed through the machine, and
lthe constantly reoccurring matter such as the4 form is printed on the bills or the like so that there is a permanent relation in the relative positions of the Variable information and constantly reoccurring matter. A machine of this kind ls shown in the Hartley Patent 1,955,806, patented April 24, 1934, wherein a printing couple is shown for printing the form on bills, passed therethrough, and another important object ofthe present invention is to provide a novel printing couple adapted for use in a machine such as thatI shown in the aforesaid Hartley patent.
The bills, checks, notices and the like are sequentially fed through machines of the kind to which this invention relates and the printing operations are performed thereon at relatively high speed to enable rapid production thereof, and another object of my invention is to provide a novel lprinting couple-for printing the form on bills or the like which may be operated at a relatively high speed, and ancillary objects are to rigidly supportA the printing cylinders of the printing couple and to enable quiet operation of the print` ing couple at relatively high speeds.
Further objects of the invention are to provide a printing couple embodying a printing cylinder bearing a printing form, such as an electroplate or the like, and a platen cylinder bearing a blanket or the like with which a make-ready may be associated, and to synchronously operate the printing and platen cylinders so that corresponding parts thereof will cooperate in each printing operation thereof whereby uniform impressions will be made thereby; to provide intermeshing gears for synchronously driving the printing and platen cylinders and to maintain saidgears in uniform intermeshing relation during operation of the printing couple; to prevent formation of offsets on the blanket of the platen cylinder by preventing cooperation between the printing and platen cylinders when no bill or the like is available for .passage therethrough; and to maintain 5 the printing and platen cylinders in printing relation s o long as bills or the like are available for passage therethrough.
A selected embodiment of my invention is illustrated in the accompanying drawings wherein 10 Fig. l is a front elevation;
Fig. 2 is a top plan in which a part of the frame is broken away;
Fig. 3 is a rear elevation; and
Fig. 4 is a vertical sectional view taken sub- 15 stantially on the line 4-4 on Fig. 3.
In the preferred form of my invention illustrated in the accompanying drawings, 5 indicates' the printing cylinder and 6 the platen cylinder of my novel printing couple. An electroplate or 20 other printing form may be retained on the printing cylinder 5 in the manner shown in the Kranz Patent 1,955,814, patented April 24, 1934, or in any other suitable way, and ink may be supplied to this printing form in the manner shown in 26 Kranz Patent 1,946,217, patented February 6, 1934, although it is to be understood that other suitable ink supplying means may be provided without departing from the purview of my invention. In order that neat and uniform impressions 30 may be made on bills, checks, notices and the like by the printing couple, the platen cylinder 6 is preferably equipped with a tensionable blanket in the manner shown in the` Kranz Patent 1,937,119, patented November 28, 1933, although 35 it is to be understood that the platen cylinder 6 may be equipped with a blanket or equivalent means in any desired way without departing from the purview of my invention as long as uniform impressions from the printing form on the print- 40 ing cylinder 5 are insured.
The printing cylinder 5 is fast on a shaft 'l journaled in a sleeve 8 of the frame 9 for the printing couple. The platen cylinder 6 is mounted on the eccentric part I0 of a shaft II which in- 45 cludes concentric bearings I2 and I3. The bear.- ing I3 is journaled in a bushing I4 (Fig. 4) secured in one end of a strap I5 and a suitable journal: is also provided for the outer free end of the shaft 'I in this strap I5. A brace I6 (Fig.` 2) 50 is secured to the strap I5 at the end thereof in which the bushing I4 is secured and this brace is rigidly connected to the frame 9. The brace IB and strap I5 aord an overhanging bearing structure for the louter free ends of the shafts 1 55 and II and increase the rigidity of the printing couple.
A gear I1 is fast on the shaft 1 and meshes with a pinion I8 fast on the shaft I9 journaled in the frame 9 and having a pulley 20 thereon about which a belt 2| is passed, said belt extending to a suitable source of power such as an electric motor (not shown) whereby power is supplied to the shaft I8 to rotate the pinion I8 and the gear I1 and therefore the shaft 1.
A gear 22 is fast to the cylinder 5 as, for example, in the manner illustrated in Fig. 4, and meshes with a gear 23 rotatably mounted on the bearing I2 of the shaft II, said bearing I2 being journaled in the frame 9. As best illustrated in Figs. 1 and 2, a pair of lugs 24 and 25 is provided on the side of the gear 23 facing the cylinder 6 and a stud 26 on this cylinder fits between these lugs. The gears 22 and 23 are of an equal size and have a corresponding number of teeth and therefore when the shaft 1 is rotated and as the cylinder 5 rotates therewith this movement is transmitted from the gear 22 to the gear 23 to the stud 26 and cylinder 6 wherefore the cylinders 5 and 6, which are of equal size, are operated synchronously.
In the present instance bills, checks, notices or the like are fed to the bight between the cylinders 5 and 6 in the form of elongated strips S along a guideway G and the sheets pass into engagement with a stop finger 21 which is shown out of stopping position in Fig. 1, but when this finger is lowered into stoppingposition it holds the sheet until the printing form on the printing cylinder 5 is in a predetermined position relative to the sheet engaged with the stop finger, Whereupon the stop finger is raised and the sheet is then fed into the bight between the cylinders 5 and 6 to' have an impression made thereon. It will thus be seen that the stop finger 21 is raised and lowered in timed relation with the rotation of the cylinders 5 and 6 and this is brought about by means now to be explained.
A vertical shaft 28 is journaled in the frame 8 and has a bevel gear 29 fast thereon which meshes witha bevel gear 30 fast on the shaft 1. Another bevel gear 3| is fast on the shaft 28 and meshes with a bevel gear 32 fast on the shaft 33 suitably journaled in the frame 9 and which may be extended into a machine with which the printing couple of this invention is associated to drive operative parts in such machine if so desired. The ratiobetween the gears 28 and 30 and 3| and 32 is preferably one-to-one and it will therefore be seen that the shaft 33 operates in timed relation with the shaft 1 and therefore the cylinders 5 and 6.
'Ihe stop finger 21 is fast on a shaft 34 journaled in bosses 35 (Fig. 2). An arm 36 is also fast on this shaft and provides an abutment engageable by an adjustable pin 31 mounted in a rocker 38 pivotally mounted on a shaft 39 suitably journaled in the frame 8. An arm 48 (Fig. 2) on the rocker 38 carries a roller 4I engageable with a peripheral cam 42 fast on the shaft 33. A stud 43 (Fig. 1) is fast in the rocker 38 and one end of a spring 44 is fast thereto and the other end of' this spring is connected to a spring anchor 45 fast in the frame 8. The spring 44 so acts on the rocker 38- that the roller 4I is urged into engagement with the peripheral cam 42. Configuration of the .peripheral cam 42 issuch that at a predetermined time in the operation of the printing couple a relieved part on the cam moves into engagement with the roller 4I whereupon the rocker 38 is moved by the spring 44 and the adjustable pin 31 engages the arm 36 and pivots the shaft 34 to elevate the stop finger 21 out of stopping position into the position shown in Fig. 1, whereupon the sheet S which has been engaged therewith is moved into the bight between the cylinders v5 and 6 to have an impression made thereon.
In order that movement of the sheet S into the bight between the cylinders 5 and 6 at the time the stop finger 21 is elevated will be assured, suitable feeding means are provided comprising the .rollers 46 and 41. The roller 41 is mounted on a shaft 48 and a part of the periphery thereof extends through an opening in the sheet guideway G. Theoller 46 is mounted on a shaft 49 journaled in the rocker 3B and, when the rocker 38 moves under the action of the spring 44 to elevate the stop finger 21, the roller 46 is lowered to thereby clamp the sheet therebelow in engagee ment with th roating roller 41 whereupon the sheet is fed into the bight between the cylinders 5 and 6. The shaft 48 on which the roller 41 is mounted has a gear 58 fast thereon which meshes with a pinion 5I carried by the stud shaft 52 journaled in the frame 9 and the pinion 5I meshes with the gear I1. The ratio between the gear I1, pinion 5I and gear 52 is such that the shaft 48 and therefore the roller 41 rotates rather rapidly and therefore a sheet clamped between the rollers 46 and 41 is rapidly fed into the bight between the cylinders 5 and 6. The pinion 5I is interposed between the gears I1 and 50 to rotate the roller 41 in a direction such that the sheet will be fed into the bight between the cylinders 5 and 6.
As the sheets move along the sheet guideway G they move under the roller 53 (Fig. 2) on shaft 54 of small motor 55 mounted on the side of the sheet guideway. 'I'his roller cooperates with the bottom of the sheet guideway to clamp the sheet and insures movement of the sheets into posi- `tion below the roller 46 and into engagement with stop finger 21. Moreover, as illustrated, shaft 54 and roller 53 are inclined relative to the extent of the sheet guideway wherefore the sheets are forced against the side of the sheet guideway,
and since this side is aligned with the printing form on printing cylinder 5 proper alignment of the sheet and printing form is assured. Preferably the roller 53 is sovpositioned that the sheet is out of engagement therewith when it engages the stop finger 21.
If the cylinders 5 and 6 are permitted to remain in cooperating relation during operation of the printing couple, offsets will be formed on the blanket on the cylinder 6 when no sheet passes between these cylinders, but this is prevented by moving the platen cylinder 6 from cooperative relation with the printing cylinder 5 when no sheet is available for movement between these cylinders.
The shaft II includes concentric bearings I2 and' I3 andan eccentric part I8 on which the cylinder 6 is mounted and this shaft II is arranged ior movement so that the most eccentric portion of the eccentric part I8 may be moved into and from a position wherein this most eccentric portion is'extended toward the cylinder 5. Such movement of the shaft II is effected by a peripheral cam 56 and a spring 51 in a manner now to be explained.
An arm 58 is fast on bearing I2 and one end of a link 58 is pivotally connected thereto. The other end of the link 68 is pivotally connected to a rocker 60 and the opposite end of this rocker is pivotally mounted in a bifurcation in the block 6I as indicated at 62. As best illustrated in Fig. 2, an arm. 63 extends outwardly from the rocker 66 and carries a roller 64 that is urged against the peripheral cam 56 lby the spring 51.,r4
Since the cam 56 -is fast on the shaft 33 it operates in timed relation with the cylinders 5 and 6 and about the time the stop finger 21 is elevated to free a sheet engaged therewith a lobe on the cam 56 engages the roller 64 and pivots the rocker 60 upwardly, thereby positioning the toggle afforded by the link 53 and arm 58 inthe position shown inFig. 3. Movement of the toggle into this position imparts movement to the link 58 which therefore rotates the bearing I2, and this rotation of the bearing l2 is such that the most eccentric portion of the eccentric part I of the shaft Il is moved to extend toward the cylinder whereby the cylinder 6 is movedinto cooperating relation with the cylinder 5 so that an impression will be made on a sheet fed into the bight between these cylinders.
As best shown in Fig. 4 the lobe on cam 56 is relatively short and hence a short time after the rocker '66 is pivoted upwardly the roller 6I moves off this lobe and the spring 51 therefore pivots the rocker 60 downwardly which shortens the toggle aorded by the link 59 and arm 58 and moves these parts into a position wherein the angle between the upper edges thereof is reduced. Such movement rotates the most eccentric portion of the eccentric part I0 away from the cylinder5 whereby the cylinder 6 no longer cooperates with thecylinder 5. The roller 64 moves from engagement with the lobecof cam 56 in this manner prior to the time the electroplate or other printing form on the cylinder 5 moves ,into
cooperative relation with the blanket or the like on the cylinder 6, and therefore the formation of offsets on the blanket-or 'the like is prevented. However, if a sheet is fed into the bight between the cylinders 5 and 6 an impression is to be made' thereon and hence means controlled by the presence or absence of a sheet in association with the stop finger 21 determines whether or not the spring 51 is to move the rocker 60 downwardly,
and if the rocker '60 is not to be moved downwardly, as when a sheet is fed into the bight be- -tween the cylinders 5 and 6, means for locking the most eccentric portion of the eccentric part i0 in its position extended toward the cylinder i5l function and hold said portion I0 in this posiion.
Such means include the collar 65 fast on the bearing l2 between the arm 58 and the gear 23, as best shown in Fig. 4. This collarfhas a notch 66 therein inwhich a stop lug 61 is .engageable This stop lug* is carried by a rocker 68 (Figs. 1 and 2) lpivotally vmounted on `the frame as indicated at 69. The rocker includes ay downwardly extending portion 1I) (Fig. 1-) that' extends below a lug 1l on arm-12A of rocker 12'that is'fast on theshaft39. One end of a spring" 13 is connected to the free end of the arm 121of the rocker 12 and the other end'of thisv spring' is suitably connected to the frame 9, and spring urges an'adjustablestop .14 mountedin therlug 1I toward 'the' downwardly extendingportion 16 .of the rocker '68. A roller is provided on the rocker 12 and this roller lis urged toward one side of cam v"56' bythe spring 13. A depression 1s is provided in this side f the cam 56 and atl a time in the y,operation`- after the rocker '60 has been pivoted upwardly the roller 15 moves into the depression 16'if a sheet has not been engaged with the stop finger 21 which, of course, means that no sheet is moving into the bight between the cylinders 5 and 6.
When the roller 15 moves into this depression the stop 14v is moved downwardly by the spring 13 and engages the extension 1|) whereupon the stop lug 61 is pivoted out of the notch "66. Therefore, when the roller 64 starts to move off the lobe on cam 56, the spring 51 may pivot the rocker 60 downwardly wherefore the cylinder 6 will be moved away from the cylinder 5 as previously explained.
The depression 16 is relatively short and shortly after the roller 15 moves thereinto the end of the-depression engages the roller 15 and pivots the rocker 12- so that the stop 14 is disengaged from the portion 10 vwhereupon the stop lug 61 moves into engagement with the periphery of disc 65.*At this time, however, the notch 66 will not be below the lug 61 but in the next operation Vwhen the rocker 60 pivots upwardly the notch 66 the roller 15 is prevented from passing down into the depression 16 and therefore the stop 14 does not engage the'portion 10 and the lug '61 remains in the notch 66.l Therefore, as long as sheets successively move into engagement with the-stop finger 21 the stop lug 61 will remain in the notch 66 and the cylinder 6 will be maintained in cooperating relation with the 4cylinder 5. When, however, no sheet is engaged with the stop nger '21, the detecting finger 11 moves into the depression 19 (Fig. 2) in the bottom `of the printingdevice guidcway, andwhen this occurs the roller 15 may move into the depression 16 withthe effect above described, that is to say, movement of the cylinder 6 out of lcooperating relation with the cylinder 5.
It will thus be seen that once the cylinders 5 and 6 have been moved into cooperating relation, this relation is maintained until a sheet fails to move into engagement with the stop finger 21 and when this occurs the stop lug 61 is moved out of the notch 66 and therefore the spring 51 will cause vthe cylinders 6 to be moved out of cooperating relation with the cylinder 5 and this, as stated, will occur beforean offset is formed on the blanket or the like on'the cylinder 6.
In addition to the extent of the shaft' 33 into the machine to operate operative parts therein othermeans such as a stacking device into which lthe sheets move. after passage thereof through the printing couplemay be operated, and to this lend a pulley 60 is fast on the shaft 1 adjacent the gear and' a belt 3| is' passed thereabout and directed to such other means to be operated 'as 'the stacking device.
speed impressions may be m-adefthereby quite rapidly. Moreover by reason of the fact that an overhanging bearing structure is provided a rigid printing couple is aiordedwhich will make un'iform neat impressions.
Furthermore unnecessary separation of the printing cylinders is avoided since once the cylinders are in cooperating relation'they are maintained in this relation as long as sheets are available for passage through the bight therebetween. When, however, no sheet is available for passage between the cylinders the cylinders are separated, that is to say, moved out of cooperating relation and in this way the formation ofoisets on a blanket or the like on a platen cylinder is prevented.
