SPECIFICATION forming part of Letters'Patent No. 720,331, dated February 10, 1903.

' Application filed May 19, 1902. V Serial No. 107,985. (No model.)

To aZZ whont it may concern:

Be it known that I, CARL RODNEY CULLEY, a citizen of the United 'States, residing at Norwalk, in the county of Huron and State of Ohio, haveinvented certain new and useful Improvements in Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and. to the characters of reference marked thereon, which form a part of this specification.

This invention relates to multicolor-printing presses, and particularly to rotary perfecting-presses of that kind.

The main object of the invention is to form a perfecting-machine which will print in sev eral colors on both sides of the paper simultaneously.

A further object is to form such a press to take and print from a roll of paper, avoiding hand-feeding and permitting continuous operation, the sheets being out after printing.

A further object is to form a rotary press with which a series of impressions may be made of any desired size without waste of paper. This object is effected by an intermittent feed and a construction which permits the web'to rest after each impression until the cylinders have rotated to the printing-point of the next impression.

With these and other objects in'view a press embodying the invention is hereinafter described, and is illustrated in the accompanying drawings, in which Figure 1 is a diagrammatic side elevation of the press. Fig. 2 is a side elevation, parts being removed. Fig. 3 is a similar end elevation. Fig. t is a side elevation, the driving gear-wheels being removed to show camopera'ted devices to bring the form and impression cylinders together. Fig. 5 is a front view of the feed mechanism.

Speaking generally, the press consists of a main cylinder having both form and impression surfaces, and minor impression and form cylinders corresponding, respectively, to the form and impression surfaces of the main cylinder. The number of form and impression surfaces on the main cylinder and the number of minor form and impression cylinders correspond to the number of colors desired, and the press is-not limited to any specific number of colors.

The machine illustrated in the drawings has four printing-couples and will print two colors on each side, and the frame is indicated at 6, the main cylinder at 7, and the minor cylinders at S, 8 8, and 8, said cylinders being mounted on shafts in suitable bearings in the frame of the machine and are driven from the shaft 9 of the main cylinder by gearwheels 10 on the various shafts. Any proper means of driving the main shaft 9 may be used.

The circumference of the main cylinder in this machine has four equal and equidistant parts 7*, 7 7, and 7 the length of each of which is one-fifth of the circumference of the main cylinder. Of thesesurfaces 7 indicates the form forone colorand 7 the form for the other color for one side of the paper, and 7 and 7 are respectively impres'sion-surfaces for the form-cylinders 8 and 8, which print the two colors on the other side of the paper.

8 and 8 are impression-cylinders for the forms 7* and 7 Four printing-couples are thus produced, two for each side of the paper, the course of which through the press is indicated by adotted line in Fig. 1. The spaces 7 between the form and impression parts are for the tympan-hooks, form-clamps, 8 &c., and their aggregate length is equal to that of one of the form and impression parts, thereby forming the remaining fifth of the circumference of the main cylinder.

The minor cylinders are spaced an equal distance apart around the circumference of the main cylinder, and the circumference of each is preferably equal to one-fifth of the circumference of the main cylinder, although this equality is not essential. They revolve, 5 however, five times to once of the main cylinder and print at every fifth revolution. They have a simultaneous reciprocal radial movement with respect to the main cylinder, so that each comes into contact with the com- IOO plementary portion of the periphery of the main cylinder during one-fifth of the rotation of the latter and is forced out to miss the same during the remainder of its rotation. To effect this, the bearing-blocks 8 of the minor-cylinder shafts slide radially in guides 6, forming a part of the frame of the machine, and the shafts are connected by rods 11 to a vibrating disk 11, which is loose on the main shaft. The disk is operated by a lever 12 of the third class, which is fulcru med to the frame at 12, pivotally attached to the disk at 12*, and has a roller 12, which runs in a cam-groove 13 on the cam-disk 13, which is fast on the main shaft. The lever is bent to bring the point of its attachment to the disk at a right angle to the roller with respect to the shaft, so as to give the disk a throw equal to the eccentricity of the cam. When the roller is moved in or out by the cam, the lever throws or turns the disk correspondingly, which motion is communicated by a toggle action with the rods 11 to the minor cylinders, forcing them into or out of contact. The motion is steadied by springs M behind the bearing-blocks. The movement, as will be understood, need only be small and is not enough to disengage the gearing. The throw of the cam is such that the minor cylinders will contact only during the proper part of the revolution of the main cylinder, such part being in this instance onefifth. The length of the rods is adjustable by screw-couplings 11". It is to be understood that the cams and connections to give the radial movement to the minor cylinders are duplicated at each end of the main cylinder.

To ink the form-cylinders 8 and 8", any old or proper inking apparatus may be used. I have indicated such an apparatus at 15, supported on the frame adjacent said cylinders. The inks will be different colors, as desired.

To ink the forms '7 and 7 on the main cylinder each a difierent color, mechanism is provided to give a radial reciprocating movement to the ink-rollers. The shafts of the ink-rollers 16 on each side of the main cylinderare supported in bearing-blocks 16*,which have vertical adjustment in frames 16 by thumb-screws 16. The frames 16", carrying the rollers, slide radially with respect to the main cylinder in guides 17 on the frame of the machine, and the motion is given through crank 17 and pin 1'7 connection with a rockshaft 17 and its crank 17 by a rod 18, which has a bearing-roller 18 in an outer cam-groove 13 in the cam-disk. Such a rod and cam at opposite ends of the main cylinder operates the inkers on opposite sides of the main cylinder, respectively. The cams are so formed that when the disk rotates the respective rollers are brought to inking contact with their respective and corresponding form, and when such form has passed the rollers of its color are forced back out of contact.

The paper web necessarily passes outside of the inkers just described, and it is threaded through the machine, as shown in Fig. 1,

around register-rolls, (indicated at 19 and 20.) It is essential that the length of the line of travel of the web around the register-rolls between each minor cylinder be an exact multiple of the length of the form being printed; otherwise the impression given at each of the small cylinders will not register with those given at the others. This length is secured by making the register-rolls 19 adjustable in their supporting-frames. I have illustrated a construction to obtain such adjustment, the supporting-frames for the rollers being indicated at 19, mounted on the frame of the machine and adjustable laterally by slot and bolt 19. For vertical adjustment the rolls are carried by bearing-boxes 19 upon rightand-left screws 19", supported by the frames and rotatable by hand-cranks 19 through shafts 19 and bevel-gears 19. The rolls may thus be raised, lowered, or extended to bring the distance to an exact multiple of the form. Any other means to effect the same result would do. In this connection I will mention that the form need not be the whole length of the circumference of the minor cylinders, since the paper is fed step by step, the length of each step being equal to the length of the impression and is otherwise at rest, although the cylinders continue rotating.

The rolls 20, adjacent the minor cylinders, are so positioned that the web is out of contact with both main and minor cylinders except during the impression period.

The paper is fed from a roll 21 between feed-rollers 22 on shafts 22, which are geared together and operated intermittently by a segment-gear 23, which is driven by intermediate gearing from the shaft of the main cylinder and at equal speed therewith, so that the feed is equal to the take of the cylinders. In the drawings these feed parts are shown before the cylinders, forming a push-feedg but they may well be placed behind the cylinders, forming a' pull-feed, pulling the web through the press.

The length of paper fed at each revolution depends on the number of teeth in the segment-gear, and this length is equal to the length of the form being printed. Various segment-gears having different numbers of teeth may be used to accommodate forms of different lengths, and the segment-gear'is so positioned that it operates the feed simultaneously with the impression.

Any proper means of attaching the type or printing-plates to the form-surfaces and tympans to the impression-surfaces maybe used.

Fig. 1 illustrates the press at beginning of impression. After making ready the impression-cylinders 8 and 8 are drawn in to couple with the form- surfaces 7 and 7, respectively, and the form-cylinders 8 and 8 are drawn in to couple with the impression-surfaces 7" and 7, respectively, and the feed begins. By the contact of the couples the pato the feed.

small cylinders have completed one revolution, or the impression, they are lifted out of contact by the cams, but not out of gear. Ccnsequently'they continue to rotate until the' main cylinder has made the remaining four-fifths of its rotation, when they are again drawn in for the next impression.

The press is designed particularly for multicolor-work on counter-check books, wherefore I have indicated a numbering-machine at X, perforators at W and Y, and a cutter at Z, which, however, are no part of my invention.

My invention is not limited to the exact mechanical construction shown, and any equivalent means may be used. Additional couples for more colors may be provided by the addition of minor cylinders and surfaces on the main cylinder. The number of colors which may be printed is limited only by the number of minor cylinders and the size of the main cylinder. The size of the minor cylinders as compared to the main cylinder is not limited to the one-to-five proportion described, but may be varied as desired, with corresponding variation of speed and cams.
