CYLINDER Patented Jan. 23, 1951 STATES ear FPHQE CYLINDER ADJUSTENG MECHANISM FQR MULTICOLUB. PRINTING PRESSES 10 Claims.

This invention relates to improvements in cylinder adjusting mechanism for multi-color printing press.

Principal objects of this invention are:

First, to provide a printing press for printing multi-color pictures in which the various colors be brought into register while the press is operating.

Second, to provide a mounting. for a color cylinder of a printing press which permits the cy1inder to be displaced angularly and transversely with respect to the main impression cylinder of the press.

Third, to provide a mounting for a color cylinder of a printing press having a rough adjustment and fine adjustment for shifting the color cylinder angulariy with respect to the main impression cylinder of the press.

Other objects and advantages pertaining to the details of the invention will be apparent from the following description. The invention is further pointed out in the claims.

The drawings, of which there are three sheets, illustrate a preferred form of my invention.

Fig. 1 is a fragmentary cross sectional View through a portion of the frame of a printing press showing a color printing cylinder mounted there- Fig. 2 is a fragmentary cross sectional View along the plane 2-2 in Fig. 1.

Fig. 3' is a fragmentary end view, partially broken away, of the structure shown in Figs. 1 and 2.

Fig. l is a fragmentary plan view of the mounting mechanism shown in Fig. i, the frame members of the press being shown in cross section.

Fig. 5 is a side elevational View, diagrammatic in character, showing the relationship between the impression cylinder and the several plate cylinders of a printing press to which my plate cylinder mounting is applied.

As is well known in the printing art, color pictures are produced by imprinting several impressions on the paper, each impression being in a different primary or neutral black color and so located or registered with respect to the other impressions that the finished picture gives the appearance of a mixture of natural colors. In order that the colors will appear natural, it is necessary that the impressions printed by the several color cylinders be accurately placed on the paper with respect to each other.

My invention provides means for mounting the plate cylinders 50 that they may be individually shifted both transversely of the press and angularly or rotationally with respect to the main impression cylinder. This permits the several printing plates to be installed on the plate cylinders in roughly adjusted position, at which time the press is started at slow speed. The presrman may then successively adjust the sevral cylinders to bring the color impressions into exact register without stopping the press.

In the drawings, reference character l indicates the frame member on the forward or operetors side of the press and 2 the rear frame member. The frame members are arranged to support a main impression cylinder 3 (see Fig. 5) four or more rolor plate cylinders d on shafts The mounting for the plate cylinders is shown in detail in the other figures.

The rear frame 2 is bored to receive an eccentric bushing 6 provided with a flange l on the rear side of the frame. The flange defines a pair of arcuate sots 8 through which the cap screws 9 extend to adjustably clamp the bushing to the frame.

The outer port on of the bushing G is recessed to rece ve the. ball bearing is held in place by the threaded collar H. It will be noted that the bearing IE3 is mounted eccentrically in the bushing and as shown in the drawings, is closer to the upper portion of the bushing. Both the collar El and bushing 6 are grooved to define annular spaces in'which oil seals, not shown. may be positioned on each side of the bearing it. By loosening the screws 9 and rotating the brshing 6 the hearing it and shaft 5 may be moved away from the main impre sion cy'inder to permit installation of the printing plate, which is not shown, on the color cylinder.

Mounted around the shaft is a sleeve 52 which is shouldered to engage the inner race of the bearing W. The bearing is held in place against the shoulder by the ring it. The outer end of the sleeve ll carries the hub Id of a driving gear 55 which has a pitch diameter equal to the diameter of the color plate cylinder 4. The hub is connected to the sleeve E52 by a set screw so as to rotate with the sleeve.

The rear face of the gear I5 is recessed as at if} to receive the body of an internal gear H. The gear H is formed with an annular flame it! around the outside thereof which fits against the rear face of the gear l5 and defines a pair of arcuate sets is through which the cap screws 28 extend. to adjvstably secure the internal gear to the external gear.

Mounted on the rear end of the shaft is an external gear 2i provided with an elongated hub section 22 which is arranged to move axially on the shaft but is secured for rotation with the shaft by the elongated keys or splines 23 (see Fig. 3). The gear 25 is meshed with the internal gear I! and the mating teeth are helical or oblique preferably at an angle of approximately degrees to the axis of the gears.

A sleeve 24 is slidably mounted around the hub 22 of the gear 2! and is provided with an annular flange 25 at its inner end which is retained against axial movement relative to the gear 2i by means of a ring as secured to the rear face of the gear 25. The rear end of the sleeve 24 is threaded to receive the center of a yoke member 21 and is also keyed to an adjusting gear 28 mounted on the sleeve between the yoke and the retaining ring 25.

The ends of the yoke 21 are secured by means of the spacer sleeves and cap screws 29 to the flange l on the bushing so that the yoke is fixed against axial movement, relative to the bushing and the frame of the press. Rotation of the sleeve 2*- by the adjusting gear 28 will therefore result in axial movement of the sleeve 24 due to its threaded connection with its yoke. The adjusting gear 28 is arranged to be driven by a pinion 30 mounted on the rear end of the shaft 3! which extends through the press to the front thereof, and is provided with an ope-rating hand wheel 32.

From the above description it should be apparent that rotation of the hand Wheels 3 and the resulting axial movement of the sleeve 2 will result in the external helical gear 2! being moved axially of the shaft 5 along the keys 23 due to the engagement of the annular flange 25 with the gear or the retaining ring 26. Since the gear 21 is nonrotatably fixed relative to the shaft and since the driving gear l5 together with the internal gear i! carried thereby are rotatable with the sleeve l2 relative to the shaft and since the gear teeth of the internal gear l1 and the gear 2| are helical, axial movement of the gear 2: as just described will result in the shaft 5 and plate cylinder 4 being displaced angular-1y with respect to the driving gear 15 as the helical teeth move axially with respect to each other. Since the driving gear I5 is permanently connected to the driving mechanisms of the main impression cyllinder, this relative angular displacement of the shaft 5 will result in a rotation of the plate cylinder 4 without a corresponding rotation of the main impression cylinder 3, therefore, the impression printed by the color plate cylinder will be displaced longitudinally along the sheet of paper being printed relative to the impressions being printed by other color plate cylinders.

Attention is now directed to the mounting structure on the forward frame l as shown on the right hand side of Figs. 1 and 4. Frame member l is apertured to receive a bushing 33 which is provided with a flange 35 along the forward side thereof defining arcuate slots through which the cap screws 35 extend to adjustabl clamp the bushing to the frame. The bushing is reces'sed to receive the ball bearing 33 which is eccentrically mounted in the bushing corresponding to the eccentri mounting of the bearing !0 in the bushing 6 on the rear frame of the press. The bearing 35 is held in place by the threaded ring 31.

Positioned around the forward end of the shaft 5 is a sleeve 38 which is shouldered to engage the inner race of the bearing 36 and threaded to receive the lock washer 39 for holding the bearing on the sleeve. An externally threaded washer 40 is threaded into the ring 3? and shouldered on its inner edge to form an annular space for an oil seal gasket 4| around the forward end of the shaft. A similar oil seal is provided at 12 between the inner face of the bushing 33 and the sleeve 38.

A plate 43 is secured to the front of the bushing 33 by the cap screws 44 and is provided with a central boss 45 defining a threaded aperture around the front end of the shaft 5. The shaft 5 is shouldered to rotatably receive the cylindrical hub 46 of the hand wheel 51. The outer surface of the hub is threaded in the boss 45 while the base of the hub is fixed axially with respect to the end of the shaft b the cap screw and washer indicated at 48.

The eccentric bushing 33 and the adjustable mounting is provided so that the alignment between the bearings 36 and the rear bearings I0 may be maintained as th color cylinder 4 is moved toward and away from the main impression cylinder. The threaded connection between the hand wheel 46 and the threaded boss 45 provides for axial movement of the shaf relative to the main impression cylinder so that the impression printed by the color cylinder may be moved transversely of the sheet of paper passing over the impression cylinder. It will be noted that axial movement of the shaft 5, resulting from operation of the hand wheel 41 will not affect the relative angular position of the color plate cylinder since the shaft is free to move axially with respect to both the gear 2| along the ke 23 and the sleeve 12.

When the structure such as has just been described is applied to one or more of several color plate cylinders of a printing press, the operator may move th plate cylinders away from the main impression cylinder by loosening the cap screws 9 and 35 and rotating the eccentric bushings 6 and 33. At this time the various color plates are installed in roughly their proper position on the plate cylinder and the bushings are rotated back to their working position to engage the plate cylinders with the impression cylinder. The cap screws 20 may be loosened and the helical gears I7 and 2| adjusted angularly with respect to the driving gear [5 to obtain an intermediate angular adjustment of the color impression with respect to the impression cylinder. The bushings and helical gears are then tightened in place and the press may be started at slow speed. Then taking the impression printed by one plate cylinder as a starting point, the

operator may successively bring the impressions printed by each succeeding plate cylinder into proper register by manipulating the hand wheels 32 and G1 in the manner just described. The adjustments can be made while the press is operating from a convenient location at the front of the press and it is not necessary to stop the press several times until all color impressions are in proper register.

The color plate cylinders have been illustrated as printing directly on the impression cylinder but the same advantages of register adjustment ma be obtained on a press employing intermediate transfer cylinders. The adjustable feature of my mounting is equally advantageous on presses using the original electrotype plates or stereotype mats.

I have described my invention in a highly practical embodiment thereof and have not attempted to show the driving connections between the main impression cylinder and the several color plate cylinders as it is felt that persons skilled in the .art may adapt my adjustable 'mounting mechanisms to presses of varying designs without further description.
