PRINTING-PRESS.

SPEGEFIIGATION forming part of VLetters Patent No. 676,453, dated June 18, 1901.

Application filed J'uly 24, 1897.

.To a/ZZ whom t may concern.'y

Be it known that I, WILLIAM H. R. TOYE, a citizen of the United States of AmericaLresiding in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Printing-Presses, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to printing-presses, and particularly to presses intended for color printing on separated sheets of paper, and has for its chief object to provide improved means forprinting (preferablyin colors) upon both sides of the sheets of paper or other material, and by means which will preserve an accurate registry and alinement of the paper during its entire passage through the press.

Generally speaking, my invention consists in combining in a single machine two conples or two sets of couples for printing, each set running in the opposite direction to the other, and in providing carrier mechanism, includinggrippers for the sheets,and transfer mechanism, including gripper-actuating devices, by which the sheet after its passage through the first printing-couple is removed therefrom and transferred to the other set of couples, through which it is carried in the opposite direction to that in which it passed through the first set. transfer directly from the carrier which transports the paper through the first set to the carrier which transports the paper through the second set, eecting this transfer by making one or both of the carriers of the flexible type and arranging and guiding them so that I bring the two carriers together at a point where they both travel in the same linear direction, while, of course, in passing between their respective printing-couples they move in diametrically opposite directions.

Reference being now had to the drawings in which my invention is illustrated, Figure 1 is a side elevation of a printing-press provided with my improvements, Fig. 2 being a plan view of the lower part of the machine, the upper part being removed, as on the section-line 1 1. Fig. 3 is a fragmentary view,

Preferably I make ther Serial No. 645,76 7. (No model.)

on a larger scale, illustrating the stop-cylinder mechanism; Fig. 4, a fragmentary View, on a larger scale, illustrating certain cam mechanism for actuating the mechanism shown in Fig. 3.' Figs. 5, 6, 7, and 8 are views of the cams shown in Fig. 4. Fig. 9 is a detail of a cam indicated in Fig. 1. Fig. 10 shows the end of the frame which is omitted for Want of room at the left-hand end of Fifr. 1. Fig. 11 is a side elevation of another form of printing-press provided with my improvement, Fig. 11 indicating a continuation of Fig. 11 to theleft hand, and Fig. 11b a contin nation to the right hand. Fig. 12 is a plan view of the machine shown in Figs. 11, 11, and 11b. Fig. 13 is an elevation of a detail of mechanism; and Fig. 14 is a detached view,

on a larger scale, of the combined miter and` plane gear-Wheel indicated at CZ in the drawings.

Referring first to the form of the machine illustrated in Figs. 1 to 10, A indicates the frame of the machine; B, the guide upon which reciprocates the carriage or slide B', having a rack B2 on its under side and typeforrns B3, B4, B5, and B6 upon its upper face, a rack B7 being also provided, running continuously along one side of the carriage or slide in position to engagethe gears G2, connected with the rollers G and G'.

C is a gear-wheel supported on a stud C2 and attached to similar gears C C', seated upon each side of it and engaging and resting upon racks C3, the gear-wheel C engaging with the rack B2, as shown in Fig. 1. The stud C2 is engaged by a yoke C4, connected Vwith a rod C5, which in turn is connected with the crank CG on a shaft C7, motion being imparted to said shaft through a gear CS, secured to one end of it and engaged with the gear C9 on the driving-shaft C10 C11, indicating fast and loose pulleys on said shaft.` It is obvious that the rotation of the shaft C7 will cause a simultaneous reciprocation and rotation of the gear-wheel O, the motion of which will be imparted through the rack B2 to the carriage B.

D is a miter-gear secured on the shaft C7 and engaged With a similar gear D on a shaft D2, said shaft having secured to it a cam D3 IOO and also cams D4 d, 4the function of which is to operate mechanism for engaging and disengaging grippers, as will be hereinafter described.

E indicates a shaft upon which are pivotally secured two rock-levers E', (for the construction of which see Fig. 4,) said rocklevers being formed with a slotted extension E2 to give passage to the shaft C7 and connected at their upper ends E3 with connecting-rods E;l and E5, one of which connects with the lever F and the other with the lever f. Secured to each of the levers E are cam-rollers, those secured to one lever being indicated at e' e2, (see Figs. 4, 5, and 6,) while the corresponding rollers on the other lever E are indicated at e3 e4, Figs. 7 and S. These cam-rollers Work in connection with the cams l, 2, 3, and 4, as indicated in'Figs. 4L to 'G and G' indicate rotary impressioncylinders fe'a'ch carrying two impression-surfaces- (indicated at g, g', g2, and g3) and each connected, as before stated,\vith a gear-.wheel G2, which is engaged by the rack B7, so that as the 'carriage' B' moves the impression-surfaces are rotated. As, however, the one impies'sion-roller-G', for instance,` which is to operate in connection with the type-forms B5 and B-,is to rotate to the right, while the other impression-roller, G, which operates in connection with the forms B3 and B4, rotates to the rleft, it is necessary to provide some means for engaging and disengaging the gears G2 with the rack B7 at proper times, and I provide for the disengagement bycutting off a portion of the teeth of the gear G2, as indicated at GS, so that when the said gear-wheel assumes the position shown in Fig. 3 it will lose Vengagen'lent with the actuating-rack. The stoppage lof the impression-cylinder in position to insure its disengagement and the Astarting of the said gear-wheel at a proper time to'insure its reugagement are secured bythe engagement of the teeth F on the end of the levers vF andfwith the teeth G4, secured to the gear-wheel or an attached part of the mechanism, the cams, as shown in Figs. 4 to 8, causing the levers to move at the proper time 'to cause these sets of teeth to engage to come to a full stop at the proper time for arresting the motion of the impression-cylinder and't'o continue their movement to rengage the gear-wheel and rack when the proper time' for such rengageinent has come.

- l-I, Fig. 1, is a gear-wheel actuated by the gear-wheel G2 and actuating turn-gears connected with the guide-Wheels Il and H2, over which and around the cylinder moves a flexible carrier (indicated at l) and having three sets of pf-tper-grippers, (indicated at I', l2, and I3.)

J is a gear-wheel engaged with the gear G2 of the roller G', actuating through the gear J the guide-wheel J2 and through the gears lettered J 3 to J 6, inclusive, to guide-wheel J 7. Another gear-wheel Js operates through a gear J2 a guide-wheel J1 and through gears J11 and ,T12 to another guide-Wheel J1? atlexible carrier (indicated at K) traveling over said guide-Wheels, as shown in Fig. l, and around the impression-cylinder G', the guiding and arrangement of the two exible carriers being such that whereas they move in opposite directions in passing around their respective impression-cylinders they move in the same linear direction at the point Where they are brought together-that is to say, as shown, Where they pass over the guide-Wheels J2 and J7. The grippers ou the carrier K are indicated at K', K2, K3, K4, K5, K6, and K7.

As in my machine the impression-cylinder of the second set of printing couples is brought into direct contact with an alreadyprinted surface, it is very necessary that it should be kept'perfectly clean and at once freed from any adhering iuk or color which would deface subsequent sheets. This may be accomplished in any convenient way. As shown in Fig. I, I provide an arm L, elastic- Yally and adjustably held onfa spindle Z7 between springs ZS and Z9 and having at each of its ends a roller L. Beneath these rollers passes a web' of some fabric suitable for cleaning the face of the roll, which, as shown, "is indicated at L2 and is drawn from a roll L3 and Wound up on a roll L4, a yielding rotative force being applied to the latter roller by a belt L5, actuated by-a pulley LG; but this force I make so vlight that itwill noty of itself cause the cleansing fabric to be moved over the roll, and for movingthe fabric I depend upon a roller L7, having a ratchet secured to it which is intermittently actuated by a paWl-lever L8, acted on by a cam L". Any convenient device for cleansing the face of the rolls may be used in lieu of this one.

M indicates the feed-board, vu pon which the sheets of paper to be printed are laid and from which they are delivered over the eX- tension M to one of the nippers I2 on the flexible carrier I. The said carrier thenv makes two rotations, so as to present the same face of the sheet first to the type-form B3 and then to the typeform B4, and then coming into registry with a nipper on the exible carrier K the edge of the paper issimultaneously, or practically so, released by the nippers of the rst carrier and seized by the nippers of the second carrier, lthis operation of the nippers being effected by the cams D4 and d4 or by any of the many well-known devices for actuating the gripping-fingers ot' paper-carrier. The paper still moving forward in the same direction is then carried through twoconnplete revolutions of the carrier K, printing rst on the type-form BG and then on the type-form B5, and is then delivered onto the receivingboards M2 and M3, the grippers being opened in position to deliver alternately on one board or the other bythe action of swinging arms O' O2, which are operated by a shaft O, given a swinging or reciprocating movement by the cam D3 on the shaft D2.

P, P2, and P3 indicate the inking-rolls, four IOO IIO

sets being provided, one for each type-form. I prefer to use three, or even more, and to make each roll of different diameter from the others in each set, although of course good results can be obtained by having rollers of (littering diameters, even though two or more are of the same diameter'. The result of this construction is that the one roller moves more frequently over the face of the type-form than the others, and the result is to smooth out the ink applied to the face of the type and insure a more perfect distribution of the ink or color.

In the modification of the machine shown in Figs. 1l to 13, A, as before, indicates the frame of the machine; B, the slide or support for the reciprocating carriage, which is indicated at B. In this machine three typeforms are shown and indicated at B3 B4 B5. In place of having a rack on the under side of the carriage this lmachine has a downwardly-extending slotted portion, (indicated at 52,) in which moves the slide c, attached to a chain c', which runs over the sprocketwheelsc2 c2, the sprocket c2 being attached to the main driving-shaft C10 and the carriagebeing carried forward and backward with the motion of the chain as the main shaft revolves. Also attached to the shaft C10 is a combined miter and plane gear-wheel, (indicated at (L) the plane face being indicated at d, Fig. 14, this construction of gearwheel being used at two other points, as shown in Fig. l2, and similarly lettered. The miter-gear on the shaft C10 actuates a similar gear d', connected to the shaft d2, which through miter-gear d8 actuates the other two gears indicated at d, and each of the plane gears d engages and drives a gear Q, which in turn engages a drive-gear G2, connected with and actuating the three cylinders indicated at G, G, and Ga. In this construction of machine the rotation of the impressioncylinders is continuous instead of intermittent; but the rollers are elevated in turn to a height which clears the type-'form without clearing the teeth of the gear-wheels G2 and Q. This lifting and lowering of the impression-cylinder is accomplished through rods T5, attached to sliding bearings supporting the rollers and at their lower ends connected with eccentrics T2, which push them up or down at propertimes, the said eccentrics being secured to shafts T4, which are moved by lever-arms T and T2, engaged by cams T T. (See Fig. 11.) The said cams T T are secured to a shaft d6, which is driven through a gear wheel d5 by a similar gearwheel d2 on the shaftd2. The shaft d also carries a cam d?, which operates to give a reciprocating motion to the lever-arm o of the rock-shaft o, which has an arm o2 at its upper end acting on a collar os to press out and in at times governed by the shape of the cam the tumbling-bolt o4. Below the arm o2 is a similar arm o5, acting on another tumblingbolt, as indicated, and acting to open the to the roller G. The nipper r is opened-by lthe action of the lower bolt 04, and simultaneously the nipper t' is caused to close upon it by the action of the engaging device S5, S,

and S', indicating guides which prevent all risk of the nipper t', opening while it is carrying the paper between the impression surface on the rolle-r G and the type-form in connection with which said impression-surface operates. On reaching the opening device (indicated at S2) the nipper 't' is opened and the paper simultaneously engaged by a nipper on the carrier K, which is first opened by the opening device (indicated at S3) and then closed by the closing device, (indicated at S4.) The sheet is then carried through a single revolution of t-he carrier K beneath the impression-rollers Ga and G and is finally deposited on the receiving-board M2.

I do not in this application desire to claim the details of mechanism of either of the two machines shown. I have illustrated two machines of materially-dierent character, but of familiar type, to show the applicability of my invention to printing-machines of varying character and do not wish to be understood as limiting my invention to any of the mechanism except soifar as the same is definitely referred to in the claims.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
