l 11 Claims.

This invention relates to inking mechanisms for printing presses.

Objects and advantages of the invention will .be set forth in part hereinafter and in Dart will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate embodiments of the invention, and together with the description, serve to explain the principles of the invention.

In printing presses of the kind with which the inking mechanisms accordling to the present invention are concerned, it is desirable to be able to discontinue the actual feeding of ink from the fountain roll to the various transfer and form rollers at thewill of the operator. Also, particularly with multi-color printing presses, this feature of being able to silence or discontinue the use with multi-color printing presses where feeding of ink from the fountain roller of each lnk feeding of ink from the fountain roll to the transfer and form rollers extremely desirable.

Furthermore, particularly in multi-color printing presses, but also in some other types of printing presses, the various inking mechanisms are mounted upon a carriage which is capable of being moved toward and away from the printing cylinders and conventionally, means are provided for bringing the various driven rollers of the inking train up to their running speed prior to effecting the last portion of movement of the carriage to place the form rollers of the inkng train in contact with the plate cylinders. With such apparatus, it is very desirable that the commencement of feeding of ink from the fountain roll to the transfer and form rollers will take place automatically either during the speeding up of the inking train or after this has reached its desired speed, but in any case, prior to the contasting of the form rollers with the plate cylinders.

Accordingly, it is the general object of this invention to provide inking mechanisms for a printing press Where new and useful means are provided for silencing or discontinuing the feeding of ink from the fountain roller to the transfer and form rollers.

It is a specific object of the present invention for each individual color is train to the transfer andy form rolls of that same ink train can be silenced at the will of the operator.

It is a further specific object off the invention to provide an inking mechanism or a plurality of inking mechanisms for a printing press, such 4as a multi-color printing press, having the inking mechanisms supported by a carriagel adapted to move relative toward and away from printing position, wherein the feeding of ink from the fountain roller to the transfer and form rollers of any one of the inking mechanisms can be discontinued -preferably manually, by an operative, together with the automatic restoration of the inking mechanism to feeding position, by movements of the carriage toward printing position.

Figure 8 is an elevational view showing the interconnection of various linkage for operating the apparatus of Figures 4, 5, 6 and 7 by movement of one of the inking carriages shown in Figure l.

Generally, in carrying out the present inveny to provide inking mechanisms particularly for tion. one of the rollers of an inking train is pick-up `roller in adapted to vbe disconnected from contact with `other rollers of the inking train under manual anoperative to which end a pick-up;

simultaneously gripped by lowered beyond the parts which the latches downwardly to act upon the bearings to throw the pick-up roller into inoperative feeding contact with the fountain roller. v

The two latches onv the operating handle are tripped from supporting studs or pins by pressing the operating arm of handle thus permitting manually to disconnect ink from the fountain roller through the pick-up roller to the last of the ink train.

One of the studs or pins is permanently xed and supports the lowered handle while the other of these -pins or studs is operatively linked to mechanism associated with the inking carriage the lowering oi' the arm The manually operated or silence the feeding of y f and spaced away therefrom,

similar manner vthe ink assembly for plate cylinder; F is mounted on a carriage which moves also ontrack 24 vby means of=rollers 21.

In' Figure lthe carriage 23 is `shown completely out of contact with its plate cylinder F.

while carriage 22 is in operative printing position with each set of the handle and latch operating Varmswcan Vbe an operative and normally retain eccentric -main frame 25, gear 3l being mounted .on

each latch toward the v which supports the inking train so that upon the being moved out of 'operative printing position, this'stud or pin will be vplaced in a lowered position and upon the return movements of the carriage toward operative printing position the lowered studs or pin will contact one of the latches pivoted to the operating handle and under urge of movements of the carriage will lift lthe latches and handle upwardly and to a position to actively associate the pick-up roller with the fountain roller for the feeding of ink.

It will be understood that the foregoing general description and the following detailed description as well are exemplary and explanatory of the invention but are not restrictive thereof.

inking carriage Referring now specifically to the accompanying drawings, and particularly Figure l, which shows somewhat diagrammatically part of one type of printing press to which the present invention may be applied, a web A passes in the direction of the arrows around an impression cylinder l rotatably driven by gears il and i2 from a shaft i3 which is in turn driven through bevel gears it and I from a main drive shaft I'S extending longitudinally of the printing press.y

Cooperating with impression cylinder' ill are a plurality of plate cylinders B, C, D, E and F each being suitably driven by a gear I1 meshing with a driving gear l5 carried by impression cylinder i0 have individual ink train mechanisms permitting individual supply of ink thereto, for example, for different colors.

Each ink train comprises a'conventional series of coacting rollers. as shown.- passing the ink forward from-a fountain roller to the form rollers 2 I, which latter actually apply ink to each plate cylinder. y

It is usual in presses of the type illustrated to' provide means for moving each set of the form rollers 2| out of contact with its plate cylinder and to this end, as shown, the ink train assembly for each of plate cylinders A, B, C. D and E are mounted on a common carriage 22 whichis supported for movements bodilytoward 'and away from impression cylinder I0 by a pluralityfof rollers 23, runningV on a track 24 supportedby the bed frame 25 of the printing` press, 1n

" -Each of the ink the form rollers in operative contact with their respective plate cylinders.

train assemblies are 'adapted to have their driven parts driven from the main drive shaft i8 and to this end, pinions 23 and 30.

are fast upon shaft I8, pinion 28 operating through a. gear 32 mounted on carriage 22 through an intermediate gear 3i mounted on a shaft 33 adaptedto operate the ink trains for plate cylinders A. B, C, D and E through bevel gear trains 34 mounted to be operated from a common shaft, and through a gear 38 mounted on carriage 26 by means of an intermediate gear 36 mounted on mainframe 25 to drive the bevel gears 31.

YIt will be noted that the intermediate gears 3i and 35 are wider than the gears intermeshing therewith this being for the purpose of allowing the inktrains to be brought up to running speed in a position close to but not in contact lwith their plate cylinders and thereafter, when a desired speed has been attained,`a contact is established between the form rollers 2i and their respective plate cylinders.`

Thus, in the press illustrated vin ing trains can be run up to speed a few inches away from their operative position, -this dimension depending on the increased width of intermediate gears 3| and 35 which permits gears 32 and 36 respectively to be operatively driven prior to engagement of the form rollers 2l with'their respective plate cylinders.

In a printing press of the general type described, it is a desirable feature that the actual supplying or passing forward of ink with respect to each individual ink train shall be stopped at the will of the operator, whereby the ink train will continue to run but without any supply of ink being fed. Thisv is particularly desirable when running the inking trains up to speed in the 'stand-oil position of the carriages 22 and 26, to prevent oversupply of lnk. For the purpose, in actual practice, it is often usual to cause throw-od of the pick-up ductor or like transfer roller which is in contact with the fountain or feed roller, and in Figure l the various pick-up rollers are shown diagrammatically at 39.

In accordance with the present invention, means are provided for silencing the actual feed of ink from the fountain roller to the rest of the ink train of each individual inking mechanism, such means being manually operated, and automatically replaced and being either separably or collectively operated for each ink train, as desired, as hereinafter brought out.

As embodied, each of the pick-up rollers 39 of the ink trains are mounted in eccentric bearings andmeans operate to move the eccentric bearings around the center of rotation of the rollers 39 to cause a suillcient gap between the operating surface thereof and the surface of the cooperating fountain roller to prevent feeding of ink from the fountain roller to the pick-up roller.

' Referring particularly to Figures 2 and 3,- the pick-up roller 39 of each inking train is mounted to rotate under frictional contact with the surface of its cooperating fountain roller by anthe other pinion 30 'operating Figure 1, ini;-`

tifriction bearings 4| whichV support the roller 38 on a shaft 42 and permits rotation of the roller relat'ive to supporting shaft 42, only one bearing 4| being illustrated at the one endof the roller 39. Shaft 42 extends outwardly, at the end illustrated, through a supporting bracketv 49 and has a reduced section 43 mounted in said bracket by an eccentric bearing 4.4, the supporting parts being duplicated at the other end (not illustrated) of the roller. 38'.u Only one end of roller 39 and its operating mechanism has been illustrated. this being the operating end, the other end being supported simply by bearings similar to 4I, an eccentric similar to 44 and a bracket similar to 49, shaft 42 terminating relatively flush with the outside of its bracket 49.

Each of the brackets 49 will be suitably supported by the main frame of the carriage 22 or 29 of Figure 1 as by angle brackets 45, whereby rotation of eccentrics 44 within brackets 49 will cause roller 39 and shaft 42 to move bodily relatively to the fountain roller 20.

As shown in Figure 4, the fountain roll 20 rotates within a body of ink 46 in a fountain 41 and in contact with the periphery of pick-up roller 39, which in turn is in contact with a transfer roller 48 of the ink train, to pass the ink forward tothe other rollers of the ink train, 'when in the ink feeding position illustrated.

Shaft 42 extends at the one end |beyond the bracket 49 by a further reduced section 48 which has attached thereon an operating lever 59, suitably keyed and feathered, as at to the shaft extension 49, and held in position thereon by'a screw 52 with lock washer 53 on a tapped bore of extension 49. Thus, swinging of the arm 59 aibout the axis of rotation of lshait 42 will cause the desired movements of roller 88 toward or away from fountain roll 29, in order to make inking contact therebetween or alternatively to cause a stoppage of feeding of ink from the fountain roll 29 to the pick-up roller 39.

In accordance with the present'I invention. means are provided, actuated manually by an operative, to effect thisfdiscontinuance of ink feeding, at any desired time, by swinging arm 59 and shaft 42 around the axis of rotation of roller 39 to disconnect roller 39 from fountain roll 29 by means of eccentrics 44.

As more clearly shown in Figures 5, 6 and 7, arm 59 has a rod 54 movably attached thereto by means of a terminating eye 55 linked thereto by a pin 56, pin 56 passing through a bore 51 in arm 59 (Figure 2) and traversing a slot 58 by which the eye 55 is embraced, permitting limited movement of the eye within the slot.

Rod 54 is spring-loaded upwardly by a spring 59 surrounding the rod and acting between a retaining washer 69 and a nut 6| on an upper threaded portion 62 of the rod, and a stop collar 62' suitably mounted on the rod 54. Adjustments of nut 6| on thread 62 permit a variability of spring pressure on arm 59 through rod 54 to cause the normal position of arm 59 to be substantially horizontal as illustrated in Figure 4, in which position roller 39 is in firm ink feeding contact with fountain-roll 29.

In order to adjust the amount of clearance to be obtained between the roller 39 and fountain roll 29 when the arm 59 is depressed, by means to be described hereinafter, to the inoperative feeding position of Figure 7, a stop screw 94 is threadedly mounted in a bracket 95 .attached to any suitable part of the frame ofv the carriage 22 or 26 of Figure 1, and the lower end of screw 6 84 contacts the tail of arm 59 depressing this to the desired point to ensure the preselected clearance under the constant throw oif of the rod 54.

Pivotally mounted in av bore 68 in bracket 49 there is arranged an arm 19, this arm being carried in the bore 69 by a long pivot pin 1| which is adapted to also pivotally carry on the same pivot a lever 'I2 for the purpose hereinafter described. Arm 19 is slotted in a center portion as at 13 to receive the rod 54 therewithin and is connected tothe rod 54 by a cross pin 14.' The lower end of spring 59 bears upon an upper'surface of the shackle 15 'through which pin 14 passes so that movements of the arm 19 upwardly and downwardly around its pivot 1| coact with movements of the lrod 54,

Plvotally mounted on arm 19 are a pair of parallelly arranged latch members 11 and 18, lthese being suitably mounted upon the arm 19 by a pin 19 which passes through an opening or slot 89 in which the latches 11 and 18 are seated. Figure 4 shows the normal ink feeding position of the latches 11 and 19 and arm 19 with the eccentrically mounted roller 39, in inking contact with the fountain roller 29 and in this position both oi' the latches 11 and 19 are retained by a spring 8| this being a leaf spring suitably mounted on the arm 19 by means of screws 82. The lowerv portion of each latch 11 and 18 terminates in a protruding section which forms the tongue of the latch and each of these sections 88 and 84 is adapted to rest upon one or a pair of'pins, which pins are normally parallel and aligned in the position shown in Figure 4 and are provided for the purpose of supporting the latch portions 83 and 84 against the action of the spring 59 and thus normally retaining the eccentrically mounted roller 39 in operating inking position.

Upon the operator desiring to disconnect the eccentrically mounted roller 39 from inking contact he has only to simultaneously grasp the arm 19 and the latch members 11 and 18 and pull these together thus causing the latch mem-l bers 11 and 19 to simultaneously swing about their pivot 19 in a counter-clockwise direction, to disengage the tongue portions 93 and 84 from the retaining pins and thus permit the arm 19 to be bodily swung in a counter-clockwise direction about its pivot 1| to cause the arm 59 to be rocked and thus eccentrically swing roller 39 out of contact. 'I'he amount of movement downwardly of the arm 19 is governed and limited by one of the pins already mentioned, this pin 89 being permanently mounted in a xed position in a bore 81 in the bracket 49 by means of a screw threaded end 88 and a nut 89 thereon. P11186 is normally associated with tongue 83 of latch 11 and when the latches 11 and 18 are grasped together with arm 19 and lowered the arm 19 engages with this permanently located pin 86 vby means of' a curved section 99 contoured to seat upon the upper portion of the pin and is retained in lowseries or links, hereinafter 'to bev described, m

such manner that upon backing away of the carriage 22 or `28', shown in-Figure l and previously described, automatically the lever' 12 will be swung about' its pivot in a. counter-clockwise whenever the.' feeding of'ink' has been stopped' for any Vpurpose the carriage with respect to that particular inking'mechanism will be' moved away from operative printin'g position and thereafter vwhen the necessary adjustments, changes or the like have been made, the said carriage will be returned toward its operative printing position. When the said carriage is close to its operative printing position with the driving gears, for example, 30 to 95, in mesh the various driven rollers oithe inking train will be brought up to speed,y as previously described, and thereafter contact between the form rollers 2| and their respective printing. plates will be made.v Just prior to that time, it is desired that the eccentrically mounted roller 39 be placed in contact with the fountain roller 20 and the transfer roller 98, to start the ink flowing from the fountain roller 20 through the train to the form rollers 2 I.

Accordingly, it is a feature of the present invention that as the carriage is moved the last small portion inwardly toward operative printing position with the various inking rollers running at speed, automatically the eccentrically mounted roller 39 lwill be thrown into operative position and for this purpose the linkage mentioned above is provided, this cooperating with lever l2 and the pin 9| as now brought out.

Referring specifically to Figure', there is illus.'- trated this linkage as generally supported in part by a carriage similar to 2| or 2B, which is shown chain-dotted at 93. Lever 'l2 has an arm 99 attached thereto and projecting substantially at right angles to form an L-shaped lever 'i2-99.

Pivotally connected to the section 99 thereof as lat 95 is a link 96 the other end of which is pivoted at 97 to a crank 98. Crank 99 is pivotally supported at 99 in a bracket |90 which bracket may be suitably attached to the side wall of the fountain 91 as shown particularly in Figures 4 and '7. The upper end of crank 99 has pivotally attached thereto, at ii, a link |02 which in turn is linkedpivotally at |09 to one arm |99 of an L-shaped lever the other arm of which |09 is adapted to swing around its pivot |99 from the full line position (Figure) to the dotted-line position shown at |01. in order to cause an alteration of the position of the pin 9|l `between the position shown in Figure 4 and the press (Figure l) in xed position, whereby asv the carriage 93 moves relative to said frame, roller will contact ||2 and progressively rock the bell crank lever |08 about its pivot. The other arm of the bell crank lever ||3 terminates in a fork ||4 which embraces a pin IIS and thus raises or lowers lever |'|8 to which lever arm |09 of the Lshaped operating lever is pivotally kept connected at ||1.

An examination of the linkage shown in Figure 8. all oi' which isin the inal position assumed by --the carriageify'lith respect to the printing parts of the press whereby the inking train is running at speed and the eccentrically mountedroller 39 is in' contact with the fountain roller- 20, will show that upon movements tov the left of Figure 8, of`

the carriage 93. The linkage will so operate as to drop the pin 9| downwardly. Thus, when the operative hal disconnected roller 39 by, as previously described, swinging arm I0 and latches l1 and 18 downwardly, the carriage 93 is rolled back or to the left in Figure 8 and dueV to the particular formation of linkage and by correct proi portioning of relative weights of the levers and Figure 8 the roller of bell crank |08 will contact the bar ||2 and will cause cooperation of the various linkage to start to raise pln49| upwardly. As seen in Figure 7, when this is done pin 9| will contact the `tongue 84'and cause the latch 19 to be bodily moved upwardly by means of this contact, thus carrying upwardly the arm vl0 and both the latches 11 and 18 all about pivot 7| and against Athe action of spring 59. The linkage is so propositipned that there is a slight overtravel of the link mechanism to permit latch l1 to pass over the stationary pin 86 and thereafter, due to the spring 8|, the tongue'93 will spring into position to rest over pin 96 so that the mechanism is again inthe position shown in Figure 4.

Thus, there has been provided means whereby manual disconnection of the pick-up roller 39 from its fountain roller 20 may beobtained at any time, whether the press is running or not, to discontinue the feeding of the ink and thereafter automatically the apparatus is -put into operative inking condition by the normal procedure of withdrawing the carriage from operative printing position toan inoperative position and returning the carriage thereafter to its printing position, the automatic throwing on into operative inking position of roller 39 taking place at the desirable time when the inking train has attained itsspeed and just prior to the actual contact between the form rollers and the printing cylinders.

Inasmuch as several inkingetrains may be connected together and carried by one carriage, for instance as'` shown in Figure 1, with respect to carriage 22, it may be desirable to simultaneously cause the return to operative inking position of any of the rollers 39 whichmay have been vdisconnected, and' accordingly, as will be seen in Figure 8, the lever ||9 which operates vertically up and down may be connected to several L-shaped operating levers similar to N14-|05, an arm i8 being shown in Figure 8 with respect to another ihking train,

While operating arm 50 which directly rocks the eccentric portions4 of the bearing for roller 99 has been shown as spring operated, it is obvious that the spring 59 could VAbe replaced by other loading means such as hydraulic means (not shown). l

While the means for permitting lever 50 to drop and thus disconnect the pick-up roller 39 from fountain roll 20-normally rely upon gravity vto cause this downward movement when thc-handle 'or arm 'I0 `and latches 'I1 and 'l0 are grasped and swung down beyond pins 8| and 0|', itis desirable in some instances to provide additional means to urge the lever 50 downwardly when disconnection is desired since the frictional resistance between vpick-up roller 30 and the transfer roller 40 may be too great to allow gravity aloneto positively and immediately cause the disconnection.

Accordingly, as a modificaton, a tension spring |20 is Provided mounted between a xed stud |2| on a suitable part of the fountain 41 and av Il is swung upwardly toward ink feeding position of rollers 20, 39 and 40, the spring |20 is extended to the ultimate position as in Figure 4. Thus, the resilient urge of spring |20 is at all times available to assist the gravitational downward swing of arm 50 upon unlatching of the means for maintaining the condition of ink feeding of Figure 4, and by selection of the correct strength for spring |20 a rapid breaking of contact of roller 39 with respect to rollers 20' and 4 0 can be accomplished without too much shock being applied to the operating parts or to the operators hand through the handle 10 and latches 'l1 and 10.
