INKING MECHANISM FOR PRlNTlNG MACHlNEs.

SPECIFICATION forming part of Letters Patent No. 716,089, dated December 16, 1902.

Application filed March 1.1900. Serial No. 6,938. on model.)

Be it known that I, THOMAS M. NORTH, a

subject of the Queen of Great Britainand Ireland, residing at New York, county of Kings,

and State of New York, have inventedcertain new and useful Improvements i n InkingMechanism for Printing-Machines, fully described and represented in the following specification. and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in inking mechanisms of printing-machines.

In order to successfully operate printingmachines, it is well understood that the ink must be thoroughly and intimately mixed,

broken up, and distributed on the rollers of theinking mechanisms before it is applied to the forms. To accomplish this result, it has been customary to allow the machines to run with the printing-couples in operation for a longer or shorter period of time, the impressions which are produced before the-ink on the inking mechanisms is brought into the proper condition being thrown away. If, however, the machine is allowed to run until the ink is brought into exactly the right condition, a considerable quantity of paper is wasted. i

. One of the objects of this invention is to pro-' duce a printing-machine in which the print ing mechanism and theinking mechanism are independently driven, so that it is possithrough the several rollers thereof without running the remainder of the machine.

A further object of this invention is to produce a printing-machine employing a plural ity of couples in which all the couples shall be driven from one train of mechanism and the inkingmechanismsifor the several couples shallbe driven from another train of mechanism, so that it may be possible to operate all the inking. mechanisms of the ma- :chine for the purpose of inking up without driving any of the printing-couples.

A further object of the invention is to produce an improved form of inking mechanism in which the form-rollers can be moved away ess-of inking up.

. A further object of the invention is to produce a printing-machine employing a plurality of printing-couples and a plurality of inking mechanisms in which the couples are driven by one mechanism and the inking mechanisms by another mechanism, devices being provided of such a character that the inking mechanism of any of the couples may be moved away from the path of the formcarrier of the couple.

A further object of the inventionis to produce a printing-machine employinga pluralityof printingcouples and a plurality of inking mechanisms in which the couplesshall be driven from one mechanism and the inking mechanisms from another mechanism and in which by suitable connections it shall be possible to simultaneously move the formrollers of all the inking mechanisms away from the path of the several form carrie rs.

With these and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be fully described in the following specification and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, which form i a part ofthis specification, and in which like characters of reference indicate the same parts, Figure l is a sectional side elevation of the machine, taken on the line 1 l of Fig. 2 and looking in the direction of the arrow in that figure. of the frame being shown in section.

Fig. 2 is a plan view, a portion Fig. 3 is a vertical cross-section on the line 3 3 of Fig. 1. Fig. 4 is a detail side elevation of the ,two end couples of the machine, illustrating more particularly the means for moving the inking-rollers away from the form-cylinders.

The machine which has been selected to illustrate a concrete embodiment of the invention is a rotary multicolor-machine, preferably printing from planographic surfaces and adapted to print one color on one side of the web and two colors on the other side.

is to be understood, however, that the invention is not limited to multicolor-machines nor to machines employing planographic surfaces.

Referring to said drawings, 1 and 2 indicate the usual side frames, in which the several. shafts of the machine are journaled, the bearings for the shafts being of any usual or desired form. The couple-which prints upon one side of the web is shown at the left-hand end of the machine, said couple consisting of a form-cylinder 3, mounted on a shaft 4, and an impression-cylinder 5, mounted on a shaft 6. After being acted upon by this couple the web passes around the surface of a large impression-cylinder 7, mounted on a shaft 8. In the machine shown a plurality of formcylinders cooperate with this large impression-cylinder 7, and while anynumber of such cylinders may be employed in the present construction two such cylinders are showna form-cylinder 9, mounted on a shaft 10, and a form-cylinder 11, mounted on a shaft 12.

In machines constructed in accordance with the invention independent driving mechanisms are provided for the printing-couples and the inking mechanisms. While the driving mechanism for the printing-couples may be variously constructed and arranged, in the present machine a power-shaft 13 is provided, said shaft being provided with any suitable driving deviceas, for instance, a belt-pulley 14. This shaft 13 extends from side to side of the machine and is journaled in suitable hearings in the machine-frame. It carries on the end opposite the pulley a gear 15, said gear being secured to the shaft in any suitable manner, as by a key 16. The gear 15 meshes with a gear 17, said gear being secured in any suitable manner, as by a key 18, to a counter-shaft 19, which also extends through the machine from side to side and is parallel with the power-shaft 13. The counter shaft 19 is extended through the side frame 1 and carries on its projecting end a gear 20, said gear being arranged to run loosely on the shaft 19, but being capable of being secured thereto in any suitable man- While the construction by which the gear 20 is secured to the shaft may be varied, in the machine herein shown the hub 21 of the gear 20 forms a part of a clutch, the cooperating part consisting of a notched sliding collar 22, which is secured to the shaft 19 by a feather 23 orin any other suitable manner. As is usual in such constructions the sliding collar 22 is provided with a groove 24,which is engaged by pins 25,said pins being carried on a yoke 26. This yoke 26 has an upward extension 27, which forms a handle, and a lower extension 28, (see Fig. 3,) which is pivoted, by means of apin 29, between cars 30, secured to the under sideof the side frame 1. The gear 20 meshes with a gear 31, whichis secured to the cylinder-shaft 8 in any suitable manner, as by a key 32. The gear 31 meshes with a gear 33,which is secured to the shaftl2 in any suitable manner, as by a key 34. The gear 31 also meshes with a gear similar to the gear 33, which is secured to the shaft 10. This gear is not, however, shown in any of the figures, it being located directly under the gear 33 and is of the same size as said gear.

.The gear 31 further meshes with a gear 35,

which is secured, by means of a key 36 or in any other suitable manner, to the shaft 6 of the impression cylinder 5. The gear 35 meshes with a gear 37, which is secured by a key 38 or in any other suitable manner to the shaft 4 of the form-cylinder 3.

From the construction so far described it is obvious that when power is applied to the main shaft, as by a belt,and the clutch-collar 22 is in engagement with the hub 21 of the gear 20 the power-shaft will drive the members of the several couples through the train of gearing which has been described. When, however, the clutch collar is disengaged or thrown into the position shown in Fig. 2, the power-shaft will rotate without rotating the members of the couples, since the gear 20, which is loose on the shaft 19 and which serves as the transmitting-gear from this shaft to the train, willnot be rotated by the shaft.

As has been before stated, an independent mechanism is provided for driving the inking mechanisms which supply ink to the several couples. While this driving mechanism may be variously constructed and arranged, in the machine shown the gear 17, which has been before described as keyed to the shaft 19, is arranged to mesh with a large gear 39, which is loosely mounted on the shaft 8 of the large impression-cylinder 7, the construction being clearly shown in Fig. 1. The gear 39 meshes with two gears 40 and 41, mounted on the shafts 10 and 12, respectively, and also with a gear 42, mounted on the shaft 6. The gear 42 meshes with a gear 43, mounted on the shaft 4, before referred to. 40, 41, and 43 run loosely on the shafts 10, 12, and 4, respectively, and it may be here remarked that while it is convenient to mount these gears on the shafts in the manner described they might be mounted in any other suitable manner-as, for instance, on studs projecting from the sides of the frame--the object being to provide a train of gearing for driving the inking mechanisms which is independent of that which drives the printingcouples.

As has been stated, the purpose of the gears 40, 41, and 43 is to provide a driving mechanism for the inking devices to be hereinafter described. While these gears may be arranged to drive the inking devices in any suitable manner, in the construction shown the gear 40 has secured thereto a gear 44, said gear being shown as slightly less in diameter than the gear 40 and being secured thereto by bolts 45. In the same manner The gears by bolts 47, and the gear 43 has asimilar gear 48 secured to it by bolts 49.

Three groups of inking mechanisms are shown, one for each of the form-cylinders 3, 9, and 11. These inking mechanisms may be of any usual or desired construction. In the machine shown they comprise fountains 50, provided with fountain-rolls 51. The inkis delivered from these fountain-rolls 51 by means of doctors 52-the operating mechanisms of which are not shown, as they may be of any ordinary formto distributing-rolls 53. Cooperating with the rolls 53 are groups of rolls 54, these rolls serving to mix, break up, and distribute the ink in the ordinary manner. The rolls 53 are driven rolls, the shafts of these rolls being provided with gears 55, which mesh with intermediates 56, which are mounted on studs 57, extending from the side frames 2. These intermediates 56 mesh with the gears 44, 46, and 48, respectively, the rolls 53 being driven in the manner described to drive the rolls 54 by friction, as iscommon in such constructions.

Cooperating with the rolls 53 are transmitting-rolls 58,of which two are shown, these rolls serving to distribute the ink from the rolls 53 to auxiliary distributing-rolls 59, of which two are shown. These rolls 59 are mounted on shafts 60, which are journaled in the side frames, and these shafts 60 are provid'edat one end with gears 61, said gears meshing with intermediates 62, which are mounted on studs projecting from the side frames 2. The intermediates 62 are in mesh with the gears 44, 46, and 48. It is apparent, therefore, that the rolls 59 are driven rolls. Each of these rolls59 delivers its ink to a group of form-rollers, of which two (marked 63 and 64) are shown, these rollers being mounted on shafts 65 66, respectively.

' Each group of form-rollers 63 64 is mounted so as to be movable toward and away from the path of movement of the forms and will in the construction shown be held away from the said path of movement until the inkingup operation is completed. While the rollers may be mounted and located in various ways so as to effect this result, preferably and as in the machine shown the shaft is mounted in bearings 67, which are carried on blocks 68. These blocks 68 are mounted on projections 69, which are secured to, preferably by being formed in one piece with, arms 70, the said arms being supported on the shafts 60 of thedistributing-rolls 59. In the same manner the shaft 66 of the rollers 64 are mounted in bearings 71, said bearings being mounted on blocks 72. These blocks 72 are secured to projections 73, which are secured to, preferably by being formed in one piece with,arms 74, which are also mounted onthe shafts 60. The blocks 68 and 72 are preferably adjustably secured tothe projections 69 and 71, this being effected in any suitable manner. In the construction shown each block is provided with a slot 75,through which passes a bolt 76, the construction being a usual one.

It willof course be understood that there are two of the arms 70one at each side of the machine and two of the arms 74one at each side of the machine-and it will be further seen that by swinging the arms 70 74 around the shafts 60 as centers the form-rollers 63 64 will be moved toward and away from the path of travel of the forms on the formcylinders and that this movement will be effected without moving the rollers 63 64 out of contact with the rolls 59.

Any suitable means may be employed to give the arms 70 74 the swinging movement referred to. In the machine shown two disks 77 are provided for each couple, one of these disks being located on each side of the machine for controlling the movement of the arms 70 74 of one of the group of form-rollers 63 64, and two cam-disks 78 are provided one on each side of the machine'for controlling the movement of the arms 70 74 of the other group of form-rollers. The disks 77 are mounted on studs 79, projecting from the side frames of the machine, and the disks 78 are mounted on studs 80, similarly supported. Each of these disks 77 78 is provided with two eccentric or cam slots 81 82, these slots being engaged by pins or rollers 83 84, carried on the arms 70 74, respectively. It is apparent, therefore, that the disks constitute cams and that by rotating them the arms 70 74 will be moved about the shafts 60 as centers, and the rollers 63 64 will be given the swinging movement before referred to.

Any suitable means may be provided for giving the disks the rotating movement before referred to, which, it may be remarked, is preferably, though not necessarily, a simultaneous movement. While the means by which this simultaneous movement may be given to all the sets of disks may be varied widely, in the machine shown each of the disks 77 is provided with a segment 85 and. each of the disks 78 with a segment 86. Each pair of disks 77 78 is arranged to mesh with a movable segment. Three such segments are provided on each side of the machine, these segments being marked 87 88 89. The segments 87 have projecting from them arms 90, and the segments 88 have projecting from them arms 91 92, and the segments 89 have projecting from them arms 93. The arms 91 of the segments 88 have connected to them. links 94,saidlinks being provided with hooked ends 95, which take over pins 96 on the arms 90, so that the two arms are connected for simultaneous movement. The hooks are closed, however, by pins 97, and when said pins are withdrawn the books will be released, so as to disconnect the segments 8788. The arms 92 are connected to the arms93by means of links 98, said links having hooked ends 99, closed by pins 100, which take over pins 101 on the arms 92.

With the construcin or out, as the case may be.

Any suitable means may be provided for moving either pair of disks. Preferably, however, and as in the machine shown there is provided a shaft 102,which extends across the machine from side to side and is provided at each end with segments 103, said segments meshing with segments 10%. These segments 101 are in the construction shown connected to the segments 88. The shaft 102 is further provided with handle-sockets 105 on each side of the machine, to which sockets are connected handles 106. With this construction it is apparent that by moving either of the handles 106 the form-rollers of each inking mechanism may be moved toward or away from the path of the forms carried on the form-cylinder.

It may happen under certain circumstances that it is desirable to disconnect the inking mechanism of any one of the couples from that of the other couples and to operate said inking mechanism separately. To this end each of the segments 87 is provided with 'a handle 107, one of these handles being of course located on each side of the machine. In the same way the segments 88 are provided with handles 108, and the segments 69 are provided with handles 109. If, for instance, it is desired to operate the inking mechanism which is controlled by the segment 87 independently of the other mechanisms the links 94 are disconnected from the pins 96, thus disconnecting the segments 87 from the remaining segments. By operating handles 107 either simultaneously or independently the inking mechanism for that couple will be thrown out.

The operation of the machine will be readily understood without further description.

It is to be understood that the mechanisms by which the invention is carried into effect may be widely varied. The invention is not, therefore, to be limited to the specific details of construction hereinabove described.
