R. L. MOSEMILLER Jan. 21, 1964 INKER 2 Sheets-Sheet 2 Filled June 22, 1962 INVENTOR Robert L. Mosemiller United States Patent 3,li,3?3 Patented Jan. 21, 1964 ice 3,118,373 INKER Robert L. Mosemiller, Wilkinsburg, Pa., assignor to Miller Printing Machinery Co., Pittsburgh, Pa., a corporation or" Pennsylvania Filed June 22, 1962, Ser. No. 204,427 6 Claims. ill. 101-348) This invention relates to an inker for a printing press and is concerned particularly with improved means for varying the amplitude of vibration of vibrator rollers of the inker.

As is well known to those skilled in the printing art, an inker for delivering ink to a form generally includes one or more vibrator rollers which are rollers which vibrate or oscillate axially while they are turning whereby to distribute and work up the ink. For reasons well known to those skilled in the art it may be desired to vary or alter the amplitude of vibration of vibrator rollers.

The mechanisms heretofore provided'for varying the amplitude of vibration of vibrator rollers have had various disadvantages. In many cases it has been necessary to stop the press to adjust or operate the means for varying the amplitude of vibration of the vibrator rollers. In other cases the mechanism for varying the amplitude of vibration of the vibrator rollers has been complex and costly and unreliable in operation, necessitating considerable maintenance work resulting in undesirable down time for the press.

I provide an inker comprising means for varying the amplitude of vibration of vibrator rollers in the inker which may be operated to vary the amplitude of vibration of the vibrator rollers from zero (no vibration) to a maximum without stopping the press and which are comparatively simple and reliable in operation. My inker comprises a driven rotary member, a crank pin Whose axis is parallel to and normally oifset from the axis of the driven rotary member carried by the driven rotary member and rotatably therewith as a unit, means separate from the driven rotary member operable while the driven rotary member is rotating for altering at will the distance which the axis of the crank pin is offset from the axis of the driven rotary member, a vibrator roller, means for rotating the vibrator roller and connections including a connecting rod between the crank pin and the vibrator roller for axially vibrating the vibrator roller, the greater the distance which the axis of the crank pin is offset from the axis of the driven rotary member the greater is the amplitude of vibration of the vibrator roller. Although the axis of the crank pin is normally offset from the axis of the driven rotary men.- ber it may in certain cases if desired be disposed in alignment with the axis of the driven rotary member resulting in absence of vibration of the roller which is normally a vibrator roller.

I provide mounting means for the crank pin carried by the driven rotary member and shiftable to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member together with means operable while the driven rotary member is rotating for shifting the mounting means. I desirably employ linkage carried by the driven rotary member on which the crank pin is mounted, the linkage being shiftable to alter the distance which the axis of the crank pin is oh"- set from the axis of the driven rotary member, together with means adjustably positionable generally axially of the driven rotary member for thus shifting the linkage. The mounting means may include parallelogram linkage which is shiftable to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member while maintaining the axis of the crank pin parallel to the axis of the driven rotary member.

In my inker alteration of the distance which the axis of the crank pin is oliset from the axis of the driven rotary member may be accompanied by slight axial movement of the crank pin, and the connections with the vibrator roller preferably comprise a connecting rod with spherical bearings at both ends to compensate for the axial component of the movement of the crank pin.

More specifically my inker may comprise a driven rotary member, a crank pin whose axis is parallel to and normally offset from the axis of the driven rotary member, mounting means for the crank pin carried by the driven rotary member and shiftable to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member, a threaded adjusting member, means with which the threaded adjusting member is in threaded interengagement so that when the threaded adjusting member is turned relatively thereto the threaded adjusting member moves in a direction generally parallel to the axis of the driven rotary member, means connecting the threaded adjusting member with the mounting means for shifting the mounting means to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member upon such movement of the threaded adjusting member, a vibrator roller, means for rotating the vibrator roller and connections including a connecting rod between the crank pin and the vibrator roller for axially vibrating the vibrator roller, the greater the distance which the axis of the crank pin is offset from the axis of the driven rotary member the greater is the amplitude of vibration of the vibrator roller.

The threaded adjusting member may be coaxial with the driven rotary member and means may be provided with which the threaded adjusting member is in threaded engagement so that when the threaded adjusting member is turned relatively thereto the threaded adjusting member moves generally axially of the driven rotary member. A member is preferably provided connecting the threaded adjusting member with the mounting means for shifting the mounting means to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member upon such generally axial movement of the threaded adjusting member, said member being coaxial with the driven rotary member and being rotatably mounted with respect to both the threaded adjusting member and the driven rotary member.

My inker comprises a frame, and I may provide a bushing stationarily mounted in the frame together with a driven rotary member mounted for rotation in the bushing, a crank pin whose axis is parallel to and normally offset from the axis of the driven rotary member, mounting means for the crank pin carried by the driven rotary member and shiftable to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member, an adjusting collar threadedly connected with the bushing so that when the collar is turned relatively to the bushing the collar moves generally axially thereof and means connecting the collar with the mounting means for shifting the mounting means to alter the distance Which the axis of the crank pin is offset from the axis of the driven rotary member upon such movement of the collar.

In a preferred form of structure my inker includes a bell crank lever pivoted to the driven rotary member about an axis offset from the axis of the driven rotary member and substantially normal to a plane containing the axis of the driven rotary member, the bell crank lever having a first arm intersecting the axis of the driven rotary member and a second arm extending generally parallel to the axis of the driven rotary member, a first link pivoted to the second arm and extending generally at right angles to the axis of the driven rotary member, a second link pivoted to the first link and to the driven rotary member insuring maintenance of the first link extending generally at right angles to the axis of the driven rotary member in all operative positions of the bell crank lever, a crank pin carried by the first link whose axis is parallel to and normally ofl'set from the axis of the driven rotary member and means separate from the driven rotary member for altering at will the angular position of the bell crank lever and thereby altering the distance which the axis of the crank pin is oil et from the axis of the driven rotary member.

The driven rotary member may have an axial bore extending through a bushing stationarily mounted in the inkor frame and mounting means may be provided for the crank pin which are carried by the driven rotary member at the portion thereof disposed outwardly of the bushing and shiftable to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member. An adjusting collar may be threadedly connected with the inner end of the bushing so that when the collar is turned relatively to the bushing the collar moves generally axially thereof. A connecting member may extend through the bore of the driven rotary member and connect the collar with the mounting means for shifting the mounting means to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member upon such movement of the collar.

In an inker employing a bell crank lever construction as above referred to I may provide means separate from the driven rotary member guided for movement generally along the axis of the driven rotary member and having a sliding connection with the first arm of the bell crank lever for turning the bell crank lever about its pivotal connection with the driven rotary member and thereby altering the distance which the axis of the crank pin is offset from the axis of the driven rotary member.

Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.

In the accompanying drawings I have shown a present preferred embodiment of the invention in which FIGURE 1 is an axial cross-sectional view of the means for varying or adjusting the amplitude of vibration of the vibrator rollers of the inker;

FIGURE 2 is an elevational view with a portion cut away showing the means for varying the amplitude of vibration of the vibrator rollers as viewed from the left in FIGURE 1 but with the elements in a different operative position than that shown in FIGURE 1 and also showing the connections from such means to the vibrator rollers whereby the vibrator rollers are vibrated;

FIGURE 3 is a view of the mechanism shown in FIG- URE 2 taken along the line ill-Ill of FIGURE 2 showing the inkcr frame in cross section and the remainder of the structure in elevation, and

FIGURE 3a is a view forming a continuation of FIG- URE 3 to the right of FIGURE 3 showing the ends of the vibrator rollers opposite the ends of such rollers shown in FIGURE 3 and the means for rotating the vibrator rollers.

Referring now more particularly to the drawings, the inlzcr and the press to which the inker is applied may be of conventional construction except for the means for varying the amplitude of vibration of the vibrator rollers of the inlter. I therefore show in the drawings only so much of the structure as is necessary to enable those skilled in the art to understand my invention.

The inker may comprise any desired number of vibrator rollers incorporated with other rollers to cooperatively distribute and work up the ink and apply it to the form as well known to those skilled in the art. For purposes of explanation and illustration 1 show in the drawings two vibrator rollers designated. respectively by reference numerals 2 and 3, those rollers being disposed at one side of the inker. Two similar vibrator rollers will be disposed in the opposite side of the inlzer but since they will be substantial duplicates of the vibrator rollers 2 and 3 and operated and controlled with respect to the amplitude of their vibratory movement similarly to the vibrator rollers 2 and 3 they are not shown.

The vibrator rollers 2 and 3 have shafts 2a and 31: respectively mounted in suitable bearings 21) and 3b repeclively as well known to those skilled in the art permitting axial vibration thereof at the same time as the rollers are rotated. The means for driving the vibrator rollers, i.e., rotating them about their axes, may be conventional. A driving shaft 47 may be driven by any suitable source of power, for example through a pulley or gear 48 fixed thereto. Also fixed to the driving shaft 47 may be a driving gear 49 which may mesh with a wide faced idler pinion Stl rotatably mounted on a stub shaft 51. Another wide faced idler pinion 52 is rotatably mounted on a stub shaft 53. The shaft 2a of the vibrator roller 2 is slidably mounted in a bearing 20 in line with the bearing 2b. Similarly the shaft 3a of the vibrator roller 3 is slidably mounted in a bearing 3c in line with the bearing 3b. The bearings 2b and 3b are mounted in one side frame member 12 of the inlzer and the bearings 20 and 3c are mounted in the opposite side frame member 12a of the inker. A gear 54 for rotating the vibrator roller 2 is fixed to the shaft 2a and meshes with the wide faced idler pinion 52 and a gear 55 for rotating the vibrator roller 3 is fixed to the shaft 3a and meshes with the wide faced idler pinions 50 and 52. Through the gearing shown the vibrator rollers 2 and 3 are rotated continuously while vibrating axially since the gears 54 and 55 are in continuous mesh with the wide faced idler pinions 50 and 52 in all axial positions of the vibrator rollers 2 and 3.

Each vibrator roller is provided with spaced collars 4 between which is disposed a roller 5 carried by one of the two cross arms 6 of a three-armed lever 7. The lever 7 is mounted in suitable hearings in the frame for turning movement about the axis 8, turning movement of the lever 7 being effected by reciprocation of a connecting rod 9 pivoted to a third arm 10 of the lever 7 at 11. As the connecting rod 9 reciprocates it oscillates the lever 7 about the axis 8 and such lever through the rollers 5 oscillates or vibrates the vibrator rollers 2 and 3. The two vibrator rollers at the opposite side of the inker which are not shown in the drawings may be similarly oscillated or vibrated by a connecting rod 9' disposed generally beside and functioning analogously to the connecting rod 9 and operatively connected with the vibrator rollers at the opposite side of the inker by means such as the means shown in the drawings connecting the connecting rod 9 with the vibrator rollers 2 and 3.

One of the side frame members of the inker is shown at 12. Stationarily mounted in a bore 13 of the frame member 12 is a flanged bushing 14 the flange 15 of which is disposed outside the frame member 12. The bushing has a projecting portion 16 which projects inwardly from the inner face of the frame member 12 as shown in FIGURE 1. The bushing 14 is rigidly fastened to the frame member 12 by bolts 17.

Journaled within the bushing 14 is a driven rotary member 18 having integral therewith a gear 19 disposed outside the frame member 12 through which the rotary member 18 is driven from the press drive by suitable gearing not shown. The driven rotary member 13 has a mounting portion 20 disposed outwardly of the inlt'er frame to which is pivoted at 21 a bell crank lever 22 having a first arm 23 extending transversely of the axis of the driven rotary member 18 and a second arm 24 extending generally parallel to the axis of the driven rotary member 18. A first link 25 is pivoted to the second arm 24 at 26 and extends generally transversely of the axis of the driven rotary member 18. A second arm 27 is pivoted to the arm 25 at 28 and to the mounting portion 2t) at 29. The mounting portion 2%, the arm 24 and the links 25 and 27 constitute a parallelogram mounting whereby the link 25 is maintained at all times substantially perpendicular to the axis of the driven rotary member 18.

A crank pin 30 is carried by the link 25 and has its axis parallel to the axis of the driven rotary member 18 but normally offset therefrom. The crank pin 39 is provided with two spherical bearings 31 and 31' received in spherical bearing portions 32 and 32' respectively at the upper ends of the respective connecting rods 9 and 9. The lower ends of the connecting rods 9 and 9 are similarly connected by spherical bearings with the respective three-armed levers for vibrating the vibrator rollers. The purpose of providing the spherical bearings is to allow for a slight change in angularity of the connecting rods when the parallelogram mounting for the crank pin 30 is shifted to alter the distance which the axis of the crank pin is offset from the axis of the driven rotary member 13 as will presently be described. Such shifting movement of the crank pin 3% has a small axial component.

The arm 23 of the bell crank lever 22 is bifurcated and the space between the opposed portions thereof is bridged by a pin 33 which passes through a block 34 which consequently is pivotally mounted to the arm 23, the block 34 extending generally upwardly from its pivotal mounting 33. The block 34 has therethrough an opening 35 through which passes the reduced end 35 of a connecting member 37 which as shown is in the form of a rod with both ends reduced. At the end 36 the connecting member 37 has spaced plates or flanges 38 disposed at opposite faces of the block 34, the assembly being maintained by a nut 39 threaded onto the end of the connecting member 37. Thus the connecting member 37 is connected through the block 34 with the arm 23 but the opening 35 is of suificient extent in the plane of FIGURE 1 to allow relative shifting between the connecting member 37 and the block 34 as the angularity of the bell crank lever 22 changes.

The connecting member 37 has a sliding fit in an axial bore 40 in the driven rotary mem er 18 and is adapted for adjusting movement in the axial direction by means presently to be described. Since the connecting member 37 is maintained against transverse movement by its lit within the bore 4% the block 34 will move up and down relatively thereto upon angular movement of the bell crank lever 22. Also a bushing 41 is provided about the reduced portion 36 of the connecting member 37 providing for relative turning of the block 34 and the connecting member 37, it being borne in mind that the driven rotary member 18 carries the mounting portion 29 on which the linkage carrying the crank pin 30 is in turn mounted. As will presently appear the driven rotary member 18 turns about the axis of the bushing 14 in operation and the connecting member 37 is free for turning movement relatively to the driven rotary member.

The inwardly projecting portion 16 of the bushing 14 is externally threaded at 42 and an internally threaded collar 43 is threadeclly engaged therewith so that upon turning of the collar it moves axially of the bushing 14. The collar 43 is open at its left-hand end viewing FIG- URE 1 but at its right-hand end is provided with a bearing 44 in which a reduced end 45 of the connecting member 37 is rotatably mounted and maintained against axial movement relatively to the collar 43. A lock nut 46 is provided for maintaining the collar 43 in desired adjusted positions axially of the bushing 14.

In operation the driven rotary member 18 is rotated through its gear 19 as above described. Rotation of the driven rotary member 13 is accompanied by rotation of the mounting portion 26 which is operatively integral With the driven rotary member 18. The parallelogram linkage or mounting means for the crank pin 31 likewise rotates with the driven rotary member 18 since it is carried by the mounting portion 20. The crank pin 30 is as above stated normally offset from or eccentric with respect to the axis of the driven rotary member 18 and reciprocates the connecting rods 9 and 9 which impart vibratory or axial oscillatory motion to the vibrator rollers.

When it is desired to alter the amplitude of vibration of the vibrator rollers the lock nut 46 is loosened and the collar 43 is turned, causing it to move axially of the bushing 14. This causes through the connecting member 37 turning of the bell crank lever 22 about the axis of its pivotal connection 21 with the mounting portion 2% which is accompanied by alteration of the offset or distance between the axis of the crank pin 31 and the axis of the driven rotary member 18. If the collar 43 is moved toward the left viewing FIGURE 1 the offset of the crank pin 3% relatively to the axis of the driven rotary member 18 is increased while if the collar 43 is moved toward the right such ofiset is decreased. The connecting member 37 is mounted so that it is free to rotate both with respect to the block 34 and with respect to the collar 43 and it is probable that in operation there will be relative rotary motion between the driven rotary member 18 and the mechanism carried thereby on the one hand and the connecting member on the other hand. It is likely that the connecting member will turn in the same direction as the driven rotary member 13 but at slower speed.

The amplitude of vibration or oscillation of the vibrator rollers can be adjusted without stopping the press. The adjustment is extremely simple requiring only loosening of the lock nut 45, turning of the collar 43 and subsequent tightening of the lock nut 46. Not only can the adjustment be effected without stopping the press but it can be effected in a very short space of time; further, the mechanism is relatively simple and reliable and inexpensive and requires a minimum of maintenance.
