Beit known that I, .IA-Mns Rows, a citizen print same on one side only.

. tion in a printing-press,

the county of Cook and State of Illinois, have in vented certain new and useful Improvements in Printing-Presses; and I do hereby declare the following to be afull, 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.. l

My invention relates toa novel construcand has for its object to provide a press through which a continuous web is passed which may be printed on one or both sides and in one or more colors in one operation; and it consists in the features of construction and combinations of parts hereinaf ter fully described and claimed.

Fig. 11 is a detail sectionon-the line 11 11 of Fig. 10.

One of the objects of my invention is to provide a press which is particularly adapted for printing sale-checks, time-tables, and similar matter in very large quantities at minimum cost, this being accomplished by printing one or'both sides in one or more colors at ,a single l operation.

Cther objects of invention will appear from the following description.

My press comprises a suitable frame l, on

which are mounted two printing-beds 2 and 8, which consist of two diametrically opposite segments of a cylinder and on the edges of which are concentric racks 4, with which the gears 5 of printing- cylinders 6, 7, 8, and 9 mesh. The said printing- cylinders 6, 7, 8, and 9 are revolubly mounted in movable journals 10 in the free ends of arms 11 of an oscillating frame 12, journaled on trnnnions 13, concentric with said printing-beds 2 and 3. The

. said oscillating frame V12 is connected at one end by means of pitmen 14 with the crankpins of spur-gears .15, meshing with gearpin ions 16 on the drive-shaft 17. At a diametrically opposite point said frame 12 is connected with the piston-rods of air-cylinders 18, which serve to steady the movements of said frame and cushion same as it reaches the limits of its movements. Said air-cylinders are mounted on trunnions and oscillate in accordance with the movements of said frame 12. The said cyl- v inders 6, 7, 8, and 9 are designed to receive printing-plates 19, extending only over onehalf or less of their circumference, the remaining surface of said cylinders forming an ink-distributing'surface which is fed by one of theinking-rollers 20, and from which the remaining rollers 21 are fed. The said inkingrollers 20 and 21 are mounted in movable journal-boxes 22, mounted in guides in the journals 10, and normally held at the inner limits of their movement by means of springs 23. The said journal-boxes 22 each comprise two members hinged together and held in proper relative position by means of set-screws 24e, said boxes being readily operated to remove the inlring-rollers to clean the latter. The inking-surface of each of the printingcylinders is of less radius than the printingsurface'of the plate 19. In order tofeed ink to the said inlring-rollers 20, I provide further ink-distributing rollers on the frame of they machine, the latter being of common construction and operation, and from the latter are fed two rollers 25, journaled in the free ends of oscillating arms 26, which are operated in accordance with the movements of the frame 12 to throw said rollers 25 into the path of rollers 27, carried and which are movable in U-shaped arms 28 on the journals 10 of the IOO cylinders 7 and 8, said rollers 27 lying normally in contact with the roller and being raised out of contact with the latter when engaged by the roller to receive ink from the latter. Similarly-mounted rollers 27 on the cylinders 6 and 9 are brought into contact with inking rollers 29 on the frame which lie always in the path of said rollers 27 f The said printing- cylinders 6, 7, 8, and 9 are so arranged relatively to the printingbeds as to print only during a part .of the movement of the frame-that is to say, that during the first and last quarters of the movement of said frame 12 said cylinders do not print by reason of the fact that during said movements the inking-surfaces of said cylinder are presented toward the beds and by reason of their smaller radius are not brought in contact with the web, two of said cylinders having passed beyond the ends of said beds, but are brought into printing position during the second and third quarters of the stroke of said frame 12. During such first and last quarters of the stroke of said frame 12 the continuous web 30 of paper is shifted to bring a fresh portion of its surface into position, while during the second and third quarters of l the stroke said web remains stationary. This I accomplish in the following manner: The

web 30 vis taken from a roll 31, revolubly mounted in suitable bearings at one end of the machine, and is trained over idlers 32, 33, and 34 and then passes over the bed 2. Upon leaving said bed it passes over a roller 35, which is intermittently rotated, as hereinafter described, and is then trained over a pair of compensating rollers 36, suitably journaled in an oscillating frame 37, which may be adjusted to any desired position and then passes over the bed 3, where the opposite side of the web is presented to the printing-cylinders. After passing over said bed 3 said web is 'trained over a second intermittently-rotated roller 38, then over a second compensator 39, thence over a third intermittently rotated roller 40, which feeds it to cutting devices 41, Where said web is cut into sheets of uniform length. The said intermittently-rotated rollers 35, 38, and 40 each carry ratchet-wheels or other suitable clutch devices 42, which are rigid with said roller, while on the shaft of the roller is a loosely-mounted rotating gear 43, which carries a clutch dog or dogs 44, which engage said clutch member when said gear rotates in one direction, while when said 'gear rotates in the opposite direction it revolves freely. Each of said gears 43-of the rollers 35 and 38 is geared -to a reciprocating rack 45, while the gears of the roller 40 mesh with a reciprocating rack-bar 46. The said reciprocating rack-bar'45 is enlarged between its ends and is' provided with a vertical slot 47 in said enlarged portion, in which a sliding crank-pin boX 48 is movable, which receives the pin 49 of a crank 50, carried by the shaft 51 of the gear-wheel 52, the latter being one-half the diameter of and meshing with said spur-gears 15. Thus said rack-bar 45 is reciprocated twice for each revolution of said spur-gear 15. During the movement of said rack 45 towardthe roll 31 the said gears 43 revolve freely, while upon the reverse movement of said rack they engage the clutch members 42 and rotate said rollers, thereby feeding the web 30 a predetermined distance. The

ydistance which said web 30 is fed must be variable in order to print sheets of various lengths, and to this end the crank-pin 49 is rendered adjustable toward and away from the shaft 5l, said pin being slidably mounted in a slot in the crank 50 and having a screwshaft 53, passing through its inner end, said screw-shaft being rotatably mounted in said crank 50 andheld against longitudinal movement therein. The rack-bar 46 is similarly r'eciprocated by means of a similarly-adjustable crank-pin of the crank 54 of a countershaft 55, geared to the spur-gears 15 and revolving at four times the speed of the latter, as hereinafter set forth. As the roll 31 is very heavy, it would be diflicult to intermittently revolve the same, particularly as its speed necessarily increases as the web is unwound in order to feed the same length in a given interval. Any attempt at intermittent movement would lnecessarily involve varying tension on the web, which aside from the danger of tearing might seriously interfere with'the register, and consequentlyI provide means for continuously revolving said roll at a uniform surface speed, so that it will feed the requisite slack between the printing intervals to be taken up by the shifting devices. This I accomplish by means of a belt 56, trained over a driven pulley 57 and over an idler 58, journaled in the free end of a frame 59, pivoted on the shaft of said driven pulley 57, said belt being adapted to rest upon the roll 31 and rotate the same by frictional contact therewith. The shaft of the pulley 57 carries a worm-wheel 60, meshing with a worm 61 on a shaft 62, which at its other end carries a longitudinally-movable friction-gear 63, which is driven from a friction-disk 64, geared to said shaft 51, said gear 63 being movable toward and away from the center of said disk 64 by means of the bellcrank lever 65 in order to vary the speed of said shaft to accord with the variations in stroke of the rack 45.

The feeding of the web from the roll may be accomplished in various ways, and I therefore do not confine myself to the foregoing devices.

In operation my press is as follows: In the position of the oscillating frame 12 shown in Fig. 1 the printing- rollers 6, 7, 8, and 9 are out of printing position and are at one limit of their movement, the web being now free to shift and in motion. The movement of the web continues until the spur-gears 15 have lOO completed an eighth of a revolution and then remains stationary by reason of thefact that said rack-bar '45 now begins its movement toward the roll 31. As soon as said spur-gears 15 have completed said one-eighth of their revolution the cylinders 6, 7, 8, and 9 are brought into position to print and may print during the next quarter of a revolution of said spur-gears 15 or during any part of said movement, and upon completion of said quarter-turn the web is again shifted and continues its movement until the next succeeding quarter-turn of said spur-gears 15 is completed, as will be obvious. rlhe cylinder 6 may print in one color and the cylinder 7 in a different color over a part of the surface, or one of said cylinders may number t-he sheets printed by the other cylinder, and this operation would be repeated by the cylinders Sand 9 on the other side ofthe web., In order to cause the impressions made by the cylinders 8 and 9 to register with those made by the cylinders 6 and 7 the compensators 36 are set in a welllrnown manner, so that the web will be so fed upon the printing-bed 3 as to bring the printed surfaces directly over the impression portion of said bed 3. In the position of the crank-pin as shown in Fig. 1 the full stroke is imparted to the rack, and the web is consequently shifted to the fullest eXtent-that is, a distance equal to the entire length of the impression-surface of each of the printing-beds and double the length of the surface printed by any one of the cylinders 6, 7, 8, and 9, so that when said web is shifted such distance the cylinder 6 Will print on one part of the surface and the cylinder 7 on another part, while cylinder 8 will print over the same surface printed by the cylinder 6 either on the same or opposite side of the web, depending upon the manner of passing said web. ByA

reducing the throw of the rack one-half all of the printing-cylinders will print consecutively over the same surface. After being thus printed the web is passed over the roller 38 A and thence over the compensator 39, which is adjusted to feed the web to the cutting devices 41 in such a manner as to cause the same to be cut o between the printed portion of the surfaces. The said cutter 41 is operated from an eccentric 66 on the drive-shaft, which is connected with a rock-shaft 67 and the latter being in turn connected with the said cutter, said devices being old and well known and It will beobvious that in shifting the web 30 it is very essential to proper register that there should be no lost motion in the shifting devices and asl with the use of ratchet-wheels there is necessarily some lost motion I prefer to use the friction-clutch devices shown in Fig. 5, in which 35 is the member rigid with the shaft of the roller and 43 the gear carrying a plurality of spring-actuated frictiondogs 44, normally held in contact with the surface of the member 35 and passing loosely over same when said gear 43 is revolved in one direction, but when revolved in the opposite direction clutching said member`35 and causing same to be revolved in unison with the gear 43 without lost motion.

My said press is adapted for a large variety of purposes and is capable of many slight modications to adapt it to certain purposes.

It the web 30 is to be printed on one side only, then it is led, as shown in Fig. 9, over the bed 2 in the opposite direction and from the upper end of the latter over the upper end of the bed 3, thus presenting only one face to be printed upon. In this manner said face may be printed in four colors in one passage through the press, or it may be printed in three colors and the cylinder 9 be provided with scoring-knives and cutters 68, by means of which the web is scored and cut for producing paper boxes. i .Y

My construction is particularly advantageous, inasmuch as the printing-beds are concentric with the pivot on which the oscillating frame 12 swings, thereby rendering adjustment very easy and obviating the numerous parts subjected to wear with which printingpresses are usually encumbered and which are a constant source of trouble.

My said press is designed mainly for the .I

cheaper classes of work, particularly vwhere a plurality of colors are desired Without the usual increase in cost resulting from the necessity of passing the sheets a number or' times through the press. I do not wish it to be understood, however, that my said press is incapable of producing high-class Work.
