Application led'ebruary 12, 191.6. Serial No. 77,818.
To all whom it may Concern: g Fig. 4 is a view similar to Fig. 1, showing Be it known that I, CARL G. PRrroHARD, a a modied embodiment of my invention;
citizen of the United States, and a resident Fig. is a view similar to Fig. 4, with the of Warren, in the county of Trumbull and transfer-cylinder separated from the form- Lao 5 State of Ohio, have invented certain new and useful Improvements in Printing Presses, o-f which the following is a specification.
My invention relates to printing-presses, and the yinvention isI embodied in improvements for separating the printing or other coacting members of the press, and also in improved devices for throwing oif the inking rollers in such a printing-press, controlled but not operated by the mechanism devised for the throwing olf of l`the 'impression, and also in any such predetermined relation therewith, as may be desired.
The objects of my invention are, among `other things, to provide a press of this general character of a simple and efficient construction, whereby the means devised for separating the printing members and for throwing of the inking rollers may be controlled and actuated, either independently of the impression throw-off, or by automatic mechanism operated by the further Inovement or rotation of the press in its normal operation after the initial throw-off.
My improved construction also vpresents other features of novelty and usefulness whereby the operating mechanism is rendered stronger and more .durable and otherwise better adapted and more convenient for use, all of which will be hereinafter set forth and claimed.
The accompanying l herein, and forming a part thereof, show several embodiments of -the invention in 0E-set presses, the same serving, in connection with the description herein, to fully explain the invention, which is not-restricted, however, to any particular form or type of printing-press construction. v

Fig. l() is a side elevation view showing a form of tripping mechanism; and

Similar numerals refer tofsimilar parts throughout the several figures.
Referring-more particularly to 3the embodiment shown in Figs. 1, 2 and 3, the frame 12 `supports the bearings for the form-cylinder 13, the transfer-cylinder 14 and the impression-cylinder 15, said cylinders being mounted on the shafts 16, 17 and 18 respectively.'` The cylinders are so constructed and arranged in the frame 12 that the transfer-cylinder 14 forming the printing couple with the impression-cylinder 15, receives its design from the form-cylinder 13. The form, transfer and impression cylinders have each` fastened thereto suitable gears whose pitch-diameter coincides withthe periphery of the respective cylinders. These gears intermesh and form the driving mechanism to secure proper rotaxtion for the cylinders. rllhe power is derived fromthe usual pulley shaft, which is connected to the Icylinder gears by a compound gear train. Since these are common forms of printingpress construction vand are well known in the art, they are not'shown in the drawings.
The shaft 17 carrying the transfer-cylinder 14 is mounted at vboth ends in the eccentric bearings 19, which, in turn, are mounted in the journals 20a secured tothe frame 12.
' as shown on one side thereof. The togglev projecting llhe bearings 19 have arms 20 frame 12,
from Hanges on the outside of the levers 21 and 22 connect the outer end o f the arm to the frame, the lever 21 being Journaled to the outer end of the arm 20, while the lever 22 is pivoted to the frame aty 23.
apo
. the interposition of the stock 37 nates the feed-table and -shaft 38 which The coil spring 24 connects the arm 21 to the frame 12, as shown, the spring bein .Strained when the y'toggle is straightene to the outer end of the lever 22 25, the other end of which is pivoted to the arm 26 mounted on the oscillating shaft 27, which may ybe actuated by the spring 24, or through a coil spring (not shown) mounted upon The hand lever 28 carrying the lug 29 is arranged to co-act with the lug 30 secured -to the shaft 27 to restore the impression.
rlhe shaft 27 is held in the position shown in Fig. 1 by the latch 31 pivoted on the shaft 32 in the bracket 33, which latch 31 engages a notch 34 in the sleeve 35 mounted on the shaft 27, as shown in detail in Figs. 10 and 11. Preferably this latch 31 would be released automatically through the trip mechanism on the feeder, which is particularly shown in Figs. 10, and 11. AIn these views, 36 desig- 37 is the stock that 1s being fed to the press. Extending transversely above the feed-table 36 and journaled to uprights on the sides thereof, is the carries the arm 38 (Fig. 1 0) connected by the rod 39 to the shaft 18 ofthe impression-cylinder 15 by any suitable means, so as to impart to the shaft 38 an oscillating movement. 40, 40 indicate grooved collars rigidly secured to the shaft 38. Adjacent each grooved collar 40 is the disk 41 aHXed tothe end of the tubular shaft 42 which is loosely sleevedon, and incloses a portion of, the shaft 38, as shown in Fig. 11. he shaft 42 carries the arm 43, the outer end of which engages with the arm 44 mounted on the block; 45 secured to the shaft 32.
' 46 indicates the trip-leverpivoted at 47 between the parallel sides of the grooved collars 40, so that its longer and heavier arm is held from falling into the aperture 48 cut in the top of the feed-table 36 by as shown in Figs. ,10 and 11. At the opposite end the lever 46 is T-shaped .to form the tooth 49, and in the peripheries of the sidesfof the collar 40, and also in the periphery of the disk 41, vare formed cut-outs 50 and 51 respectively. Ordinarily .the tooth 49 rests against, or is in proximity to, the periphery 0f the disk 41; it can en age with the cutout 50 of the collar 40 on y when it can fall into the cut-out 51 of the disk 41. this occurs, the disk 41 with its shaft 42, which are normally at rest, are locked to the shaft 27 itself.,
When
and turn ywith theoscillating shaft 38. The entrance of this tooth 49 into locking engagement with thedisk 41 will occur upon the failure or interruption in the feed supply. When thestock 37 is in proper position, as shown in Figs. 10 and 1l, the curved longer arm of the trip-lever 46 will engage therewith and willbe prevented from lower-v ing into the aperture 48, and from turning suflciently to interlock with the disk 41. lf the stock 37 should, at any time, be interrupted or absent, the longer arm of the triplever 46 will fall of its own weight, into the aperture 48, thereby causing the tooth 49 to interlock with the cut-out 51 in the disk. Thus the tubular shaft 42 will be caused to oscillate with the shaft 38 so as to cause the arm 43 to lift the arm 44 to release the latch 31 engaging the notch 34 in the sleeve 35 on the shaft 27. Through this movement of this herein described mechanisms, the spring-impelled shaft 27 is partially rotated to swing the eccentric bearing' 19 to throw off the impression by separating the transfer cylinder 14, from the formfcylinder 13 and impression-cylinder as shown in Fig. 2, all controlled automatically by the stock.
designate a series of inking rollers mounted upon a series of transverse shafts 53 carried inthe slotted bearings 54. Each inking roller 52 has a cylindrical bearing 55,
concentric with its shaft 53, adapted to he4 engaged by suitably shaped cam-surfaces 56 formed in the upper portion of the rocking cam 57 loosely mounted on the shaft 16 of the form-cylinder 13, the bearings riding upon the high part of the cam 57 to lift the inking rollers from the form-cylinder 13, as shown in Fig. 3. The rocking movement of the cam 57 is accomplished hy the following mechanism: 58 indicates a rockleverpivoted at 59 to the frame 12, so constructed and. arranged that. its outer end 60 may be pushed downwardly by the lug 6l preferably mounted on the 'periphery of the transfer-cylinder 14 throughthe rotation of this cylinder when separated; from thepform and transfer cylinder', as shown in Fig. 2, whenever the throw-off of the impression occurs. When the three cylinders are ineprinting relation, as shown. in Fig. l, the path of rotating lug -61 will besuch as to avoid engaging with the end 60 of the lever 58. Instead of being .axed to the periphery vof ,the cylinder 14, the lug 61 may be mounted on the cylinder shaft 17, or on the cylinder gear, either inside or outside `the frame 12. 'Howeveig its location upon the transfer-cylinder itself, as shown, is preferably the most convenient arrangement in press construction. The opposite en d 62 of the lever 58 is connected by the link 63 with the lever 64 pivoted at 65 in the frame 12, the outer arm 66` of which forms a latch in conjunction with the notch 4o v liquely in `its eccentric bearings 19 away 67 in the collar 68 mounted on the shaft 69, journaled in the frame 12, which shaft 69 is adapted to be partially rotated upon," the release of the latch- 66 through a coil'i` spring 70, one end of which is secured tothe outer end of thearm 71 mounted on the shaft 69, and the other end to the pin v72 in the frame 12. Other suitable means 'for securing a partial rotation of the shaft 69 may be utilized such as the usual spring coiled about the shaft itself. The flange 73 secured to the cam 57 carries a pin 74 which engages and co-acts with the socket 75 formed in the outer end of the arm 71, as shown. The coil spring'76 secured to a lug 77 onthe link 63, and also to the pin 78 in the' frame 12, serves to hold the latch 66 in engagement with the notch 67, until this latch is released by the. engagement of the rotating lug 61 with the arm 60,' as shown in Fig. 3. 1f desired, thehand-lever- 79 mounted on the shaft 69 may be used as a means for re-setting this shaft 69`by the engagement of the latch 66 with the notch 67 in the collar 68, the lug 8O on the handle -7 9 co-acting with the lug 81 mounted on the collar 68 to accomplish this purpose.
The operation of the hereinbefore described 'me'chanism is substantially as foll lows: Whenever the stock 37 is interrupted .or is absent from the feed table, the triplever 46 acts to release the latch 31 which causes a partial rotation of the spring-impelled shaft 27, the arm 26 movingto the right, as shown in Fig. 2, which breaks the toggle-levers 21 an-d22 through the link connection 2.5. Thebreaking of this toggle connection immediately causes the arm 20. to swing upwardly, as shown in Fig. 2, which causes the transfer-cylinder 14 to move obfrom both form-cylinder 13 and impressioncylinder 15, thereby breaking the printing relation of the three cylinders, `and throwing 0H the impreion, all as shown in Fig. 2. 1t will be noted from' the action ofthe press as shown in Fig. 2, that While the impression throw-off has rtaken place, the inking rollers 52 have not as yet been tripped to throw same from the form-cylinder 13, the lug 61 being about to engage the outer end of the rock-.lever 58. As the transfercylinder 14 continues its clock-wise rotation in the rotation of the press, the lug 61 through its engagement with the end 60, rocks the lever 58 which, through the link ,63, rocks the lever 64 to release the latch 66 from its engagement with the notch 67 formed in the collar 68. The sha-ft 69 is then partially rotated in a clock-wise direction through the action of the coil sp-ring 7 0 acting on the outer end of the arm 71 mounted on the shaft, and lifts the flange 73 secured to the cam 57, causing the latter to rock on 55 the form-cylinder shaft 16 toward the left,
whereby the inking rollers 52 are lifted from the form-cylinder' 13 through the roller bearings 55 riding upwardly onthe high part of the cam-surfaces 56 in -the cam 57, all as shown in Fig. 3. The hand-lever 28 is lifted to restore the printing relation of the cylinders and the engagement of the latch 31 with.
the notch 34, and in like manner the handlever 79 is raised to reset fthe latch 66, whereby the outer end 60 of the rock-lever 58 is lowered beyond the path of the lug 61, as
the transfer-cylinder is rotated, as shown by the arrows, when printing rel-ation is restored. a
It is obvious from the construction and operation of' this mechanism, as herein shown and described, that the inking rollers may be thrown off from the form-cylinder -b pi-Tession throw-olf, and also by means automatically operated through the continued movement of the press.
In the embodiment of my invention illustrated in Figs. 4, 5 and 6, l employ the same mechanism for throwing olf the inking rollers 52, as has been shown and described with reference to the embodiment illustrated in Figs. 1, 2 .and 3, but the modification is made .in the construction utilized for accomplishing the throw-olf of the transfer cylinder 14. Fig. 4 shows all three cylinders in contact; Fig. 5 shows the transfer-cylinder 14 separated from the form-cylinder` 13, but remaining in contact with the impression-cylinder kder 14 separated from all three cylinders and the inking rollers out of contact with the forni-cylinder 13. This arrangement first separates the form-cylinder 13 and transfercylinder 14 to prevent inking the blanket on the transfer-cylinder, and subsequently the printing impression and the inking rollers are thrown ofi'. l
Referring to the construction shown in Figs. 4, 5 and 6, the shaft 17 of the transfercylinder 14 is mounted in the eccentric bearings 19. rlhe shaft 17' is also mounted in the journal-'box 82-mounted to slide radially on the ways 83 in the frame 12 to and from the impression-cylinder 15. `The compression spring 84 is secured in the opening 85 formedv in 4the frame 12 to normally force lthe journal-box 82 outwardly, so as to'separate the transfer-cylinder 14 from the impression cylinder 15. 'The transfer-cylinder 14 is held in 'contact with the im ressioncylinder 15 against the tension of t e spring 84 by the following mechanism: Pivoted at 85 to the frame 12 is the rock-lever 86, the outer end 87 of which is arranged to be engagecl` by the rotating lug 88 mounted on the cylinder 14, in the saine manner as the rotating lug 61 so as t0 engage the outer end 87 of the rock-lever 86 through the rotation of nthe transfer-cylinder 14 when it is separated 15; and Fig. 6 shows the cylin-y when the latch 89 is in from the form-cylinder13, as shown in Figs. 5 and 6. The opposite end 89 of the rocklever 86 constitutes a latch which engages in a notch 90 formed in the collar 91 mounted on the oscillating shaft 92 journaled in the frame 12. Secured to the shaft 92 is the arm 93 to which is fastened the'coil spring 94, attached to the frame 12v by the pin 95. The arm 93 is pivotally connected at 95a with the arm 96- journaled in the bracket 97 carried on the journal-box 82, the arms 93 and 96 forming a straight toggle connection between the journal-box 82 and .the shaft 92 locking engagement with the notch 90, the spring -94 being strained. The spring 98 acts to normally hold the latch 89 in engagement with the notch 90.
When the cylinders are inf. the position shown in Fig. 5, through the movement of the eccentric bearings 19, which separates the transfer-cylinder 14 from the form- .cylinder 13, as hereinbefore shown and described, the further rotation of thetransfercylinder carries the lug 88 by the outer end 60 and' engages the end 87 of the rock-lever 86, since the arrangement is such that the lug 88 engages witlrthe arm 87 only when the cylinders 13 and 14 are separated, the cylinders 14 and 15 being in contact, as shown in Fig. 5; the lug 61 engages the arm 60 when all three cylinders are separated, as shown in Fig. 6. The continued'rotation of the transfer-cylinder 14 forces the end 87 downwardly and rocks the lever 86 so as to release the latch 89 from the notch 90. This release of the latch 89 causes the shaft 92 to partially rotate contra-clockwise through the pulling action of the coil spring 94, thereby breaking the toggle connection between the shaft 92 box 82, as shown in Fig. 6, enabling the outward force of the compressed spring 84 to immediately move' the transfer-cylinder 14 radially away from the impression-cylinder 15 and to throw o" the impression; Meanwhile the lug 61, contacting with the arm 60 of the rock-lever 58, has tripped the latch 66 to throw oli the inking rolls as has been already set forth when describing the construction shown in Figs. 1, 2 and 3. Therefore, to conclude the cycle of operations, Fig. 6 illustrates this modified embodiment with the three cylinders" all separated and' the inking rollers 52 out of contact with the form-cylinder 13, the interruption in the feed of the stock having inaugurated the action of the mechanism to throw oli? the transfer-cylinder from the form-cylinder 13. The latch 89 is reset with its engaging notch 90 by the hand-lever 99 carrying the lug 100 coacting with vthe lug 101 on the collar 102, mounted on the shaft 102. The collar 102 carries the ar'm 103 connected by the link 104 to the arm 105, mounted on the shaft 92.
and the sliding journal- When the hand-lever 99 is raised to move the arm 103 to the left, the shaft 92 is partially rotated in a clockwise direction, to reset the latch 89 in the notch 90, when the locking engagement is thereafter preserved through the action of the coil spring 98 pulling the lever 86 to the right, slightly outside the path of the lug 88. i
By properly positioning the lugs 61-and 88 on the cylinder 14, the successive tripping operations, because of their respective engagements with the rock-levers 58 and 86, through the bodily displacement of the cylinder 14, as before described, can be timed at any intervals desired and' in either succession. Furthermore, the position of the lug 61 is such as to accomplish the throwing ofi' of the ink rolls 52, when they are clear of the plate on the form-cylinder 13, thereby securing uniform inking of the entire printing surfaces of the plates.
1n the modified embodiment of my invention, illustrated in Figs. 7 and 8, the transfer-cylinder 14 moves obliquely away from the form-cylinder 13, and the impressioncylinder 15 has a right-angled movement away from the transfer-cylinder 14. l employ the same mechanism for throwing ott' the inking rollers 52, as has been heretofore shown and described with reference to the former constructions illustrated inthe preceding iigures. In the embodiment shown in Figs. 4, 5 and 6, the transfer-cylinder 14 had two movements at substantially right angles with each other, so as to break oli the printing relation of the three cylinders, one from the form-cylinder 13, and the other away from the impression-cylinder f5.' Ylin the present embodiment, as shown in Figs. 7 and 8, another construction and arrangement is illustrated, in which vthe transfercylinder 14 has only a single radial movement, controlled by the sheet, away from thef throw-ofi'l movement is accomplished by moving the impression cylinder 15, its shaft 18 being mounted .in eccentric bearings, as shown in these gures.
Referring to this modified form of oonstruction, as shown in Figs.`7 `and 8, the shaft 17 of the transfe -cylinder 14 is mounted in the journal-box 106 to'slide radially in the ways 107'formed in the frame 12, at substantially right angles to the ways 83 shown in Figs. 4, 5 and 6. This permits a separating movement between the cylinders 13 and 14 without destroying the latters contact with the impression-cylinder 15. The coil compression spring 108 is secured in the opening 109 in the frame to normally force'the journal-box 106 outwardly, so asvto separate the cylinder 14 from the cylinder Y -cylind'er 15, while the second or impression I. the spring 116, which tact with the form-cylinder 13 by the stockcontrolled tripping and latch mechanism herein described in connection with the construction shown in Figs. 1, 2 and 3, and need not be again described in detail. The journal-box 106 carries the bracket 110 formed on its lower end, which supports the togglelevers 111 and 112, the lever 112 being pivoted to the pin 113 aiiXed to the frame 12, as shown. Likewise -pivoted to the pin 113 and mounted at substantially right angles to the lever 112, is the arm 114 connected by the link 115 to the arm 26 on the oscillating shaft 27,' the construction and operation of which has lbeen heretofore described. rlhe coil spring 116, connecting the arm 114 to the frame, is strained when the toggle-levers 111 and 112 are in their straightened position, as shown in Fig. 7. When the trippingy mechanism shown in detail in, Figs. 10 and 11,` releases the latch 31, the link 115 is moved upwardly in the direction of the arrow shown in Fig. 7, through the force of likewise breaks the toggle-levers 111 and 112, thereby enabling the compression spring 108 to immediately movethe sliding journal-box 106 downwardly, which movement will, at once, separate the transfer-cylinder 14 from the formcylin'der 13,`as clearlyv shown in Fig. 8.
The' mechanism for throwing off the inking-rollers 52-in this form of construction (Figs. 7 and 8), after the second or impression throwv off is accomplished, is substantially the samein construction and mode of operation as that shown and. described in connection with the embodiment illustrated in Figs. 1, 2 and 3, the spring 117, connected to the arm 62 of the rock-lever 58 and to the frame 12, serving to hol-d the latch 66 in locked engagement with the notch 67 in lieu of the spring 76, as shown in Figs. 1, 2 and 3. "The mechanism for accomplishing the second, or impression throw-off, whereby the impression-cylinder 1'5 is obliquely swung away and separated from the transfer-cylinder 14, is as follows: The shaft 18 carrying the impression-cylinder 15 is mounted in eccentric bearings 118, which, in turn, are mounted in journals 119 secured to the frame 12. The bearings 118 have arms-120 projecting from flanges on the outside of the frame, as shofwn.. The toggle levers 121 and 122, pivoted at 123, connect the arm 120 with the oscillating shaft 124. The coil spring 125 connects the toggle lever 121 to the frame, this spring being strained when the toggle levers 121 and 122 are straightened, as shown in Figs. 7 and 8.. Pivoted at 126 to the lever 122 is the link 127, which affords `a rigid connection from the lever 122 to the arm 128, secured on the oscillating shaft 129, journaled in the frame 12, as shown. The shaft 129 carries' a collar 130 having a notch 131 cut therein, so formed as to be engaged and locked in position by the rocking latch-lever 132 pivoted to the frame 12 at 133. The lower end 134 of the latch 132 is so oonstructed and arranged as to be engaged by the rotating lug 135 mounted on the transfer-cylinder 14, when that cylinder has been displaced and is separated from the formcylinder 13, theconstruction shown in Fig. 8, illustrating this feature inthe construction with the lug 135 albout to engage the end 134 to trip the latch 132, to throw off the impression-cylinder 15 by allowing the spring 125 to break the toggle-levers 1251 and 122, to move the link 127 to the left and to swing the arm 120 in the direction shown by 'the arrow, to move the eccentric bearings 118, thereby separating the cylinder 15 from its printing relation with the cylinder 14. 1t is obvious that this movement of the eccentric bearings 118 may be accomplished by av suitable spring coiled about the shaft 129, or by any other convenient mechanism actuated by the latch-lever 132, through proper connecting devices.
' The latch-lever 132 may be reset in the notch 131 by the hand-lever 136 carrying the lug 137 coacting with the lug 138 on the collar 139 mounted on the shaft 124, thereby rotating the shaft 129 contra-clockwise, and straightening the toggle-levers 121 and-122, while simultaneously placing the spring 125 again under tension. By properly adjusting and positioning the lugs 61 and 135 Qn the transfer-cylinder 14, the successive trip- -ping operations, through the respective engagements with the trip- levers 58 and 13,2, can be timed at any intervals desired, and in either succession. However, it is preferable to so arrange the throw-oifs so as to cause impression ,cylinder -to throw off before the inking rollers are separated from the' form-cylinder, by making such appropriate changes in the arrangement of the trip-levers and their respective coperating lugs mounted on the transfer-cylinder 1.4, as 'will accomplish these successive movements in the order desired, all of which will be readily understood by those, skilled in this art.
In Fig. 9'1 have shown a still further variation in the mechanism for successively -throwing-0H the respective cylinders from contact with each with the other, b'yr'showing both the' transfer-cylinderv 14 Vand the impression-cylinder 15 mounted and operable in eccentric bearings. 1n this constructhe feed vof the stock 37 lon the feed-table 36, f
this initial movement separating only the transfer-cylinder 14 from the form-cylinder 13; the .second eccentric movement is operable by the lug mounted on the transfercylinder 14, now separated from the formcylinder 13, engaging with the latch-lever 4 132 to throw off the impression-cylinder 15 from the transfer-cylinder 14, as has been heretofore described with relation to the construction shown in Figs. 7 and 8. Thereafter the lug -61 trips the rock-lever 58 to release the latch 66, which controls the operation of the mechanism for throwing ,off the inking rollers, as has been already described in connection with the construction shown in Figs. 1, 2 and 3. v
It is apparent that the impression-cylinder 15 may be initially separated from the transfer-cylinder 14, in the cycle of operations cf the press, in which case the lugs 61 and 135 would be suitably mounted upon the impression-cylinder 15, and the respective trip-lever mechanisms operable through engagement with these lugs, would be so arranged'in proper relation thereto as to insure the predetermined succession of throwoffs inthe press.
In the embodiments of my invention shown in Figs. 12 and 13, I have illustrated forms of oflset presses in which, in each case, the actuating lug is mounted on a cylinder which is not aected by the initial throw-off movement.
In the construction shown in Fig. 12, the transfercylinder 14 is alone mounted and operable in eccentric bearings 19, as shown in Figs. 1, 2 and 3. In this form, the eccentric bearings 1,9 are first actuated, as shown in Fig. 2, by the tripping mechanism controlled by the absence or interruption of the feed of the stock 37 on the feed-table 36, or manually-operated means may be .used to inaugurate this initial movement, which separates the transfer-cylinder 14 from both formcylinder 13 and impression cylinder 15, as already set forth. Mounted on the pin 136 on the outside of the frame 12 is the lever 137, the upper arm of which has the slotted bearing 138 adapted to engage with the studor pin 139 on the end of the shaft 17. The lower a-rm 140 (shown in dotted lines) of the lever 137 is onthe inside of the frame 12, and carries, on the pivot 141, the rock-lever 142, theouter end 143 of which lever 142 isv adapted to engage the lug 144 mounted on the impression-cylinder 15 when the lever 137 is oscillated through the separation of the transfer-cylinder 14 from the other two cylinders 13 and 14 just described. The other arm 145 of the lever 142, is connected by the link 146 to the lever 64, which operates the latch 66 in the notch 67, to throw` off the inking rollers 52 from the form-cylinder 13, all as has been hereinbefore described in connection with the construction and operation of the presses shown in Figs. 1, 2 and 3.
In the construction shown in Fig. 13, the impression-cylinder 15 is alone mounted and operable in eccentric bearings 118, as in the forms shown in Figs. 7, 8 and 9. In this Fig. 13 construction, the eccentric bearings 118 are first operated bythe tripping mechanism heretofore shown .and described, or by manual means, so as to separate the impression-cylinder 15 fiom the transfer-cylinder 14. This may be accomplished by the following mechanism: Mounted on the arm 120 is the toggle lever 147 pivoted at 148 to the other toggle lever 149, which is pivotally mounted on the pin 150 secured to th'e frame 12. The lever 149 is connected by the link 151 to the arm 152 carried on the rockshaft 27. The compression spring 153 is secured between the lever 149 and the frame, and breaks the toggle levers 147 and 149 from their straightened position, as shown, to move the arm `120 to the left, whenever the latch 31 is released from the notch 34 in the sleeve 35 mounted on the shaft 27. Pivoted on the ypin 154 on the outside of the frame 12 is the lever 155, Ythe upper arm of which has the slotted bearing 156 adapted to l engage with the stud or pin 157 on the end of the shaft 18. The lower arm 158 (shown in dotted lines) of the lever 155 is on the inside of the frame 12, and carries on the pivot 159 the rock-lever 160, the outer end 161 of which lever 160 is adapted to engage the lug 162 mounted on the transfer-cylinder 14, when the lever 155 is oscillated through the separation of the impression-cylinder 15 from the transfer-cylinder 14, as hasv been already described. The other end 163 of the lever 160 is connected by the link 164 to the lever 64 which operates the latch 66 in the notch 67 to throw off the inking rollers 52 from the form-cylinder, all as has been already set forth in connection with Figs. l, 2 and 3.
The foregoing constructions all embody the principles of my invention as applied to off-set presses, but it is obvious that my invention is applicable to other forms of printing-presses, and that other combinations and modes of operation may be made; the foregoing being suflicient to disclose the underlying principles and advantages involved. The actuating lugs or other engaging members are preferably disposed and mounted on the different coacting printing members constituting the press, yet they may be arranged and operable upon other parts of the press, so as to insure the predetermined sequence of operations desired, so long as they are disposed to be thrown into the path of some intermediate device, the operation of which is controlled and inaugurated by the initial movement in the press.
