, 10 indicates a traveling type-bed mounted in the framework of said press and recipro cated hack and forth in any well-known and understood manner, asby drlving-rod 11,

pivoted at-"one end to slide-block 12, on 'which said traveling-bed is mounted, and

driven in any appropriate manner not shown.

' As the main press 8 ma be of any wellknowngtype of traveling presses operating in any well-knownmannor, to perfect "a .web passing through the same, only apo'rtion-ot said press is shown, showing the form in which I have' embodied my invention,-in order not to encumber the drawings with useless illustrations of parts which are perfectly fai'niliar to those skilled in the art and will be re'adilyunderstood.

13 indicates a supplement ,press located adjacent to and the main press workl i. h

15 indicates a carriage having side-bars 16. This carriage 15, by means of slideblocks 18, preferably formed integral'with in suitable registry with 8' and having a framethe side bars 16, is slidingly mounted in waysor guides 19 the framework of the press so as to'reciprocate back and forth in said guides longitudinally of the press.

20 indicates rods secured at one end to the outer end of the traveling bed 10 of the main press'S and at the other end -to the carriage 15,whereby, asthe traveling bed 10 is reciprocated back and forth on its press, the carriage 15. is correspondingly reciprocated in the supplement press 13. f i V 2122 indicate impressione cylinders provided, respectivelyffwith shafts 2324 at each end and'carried by the carriage. 15 in the manner hereinafterfdescribed.

25-26 indicate gears which are securedat one end of ,thd cylinders 2l-22, respeetively, and which are adaptedto mead reder press an enlarged detail being ed web-printing spectively, with racks 27-28 mounted on the framework 14 of the supplement press 13 whereby as said carriage reciprocates the impression-cylinders are rotated over the type-beds.

2930 indicate stationary type-beds, mountedupon the framework 14, adapted to contain forms 31-32 which coact with the impression-cylinders 21- -22, respectively, to print the paper passing .between them.

Referring particularly to Figs. 6 and 7, where these parts are best shown, 33 indicates eccentrics which are journaled-in suitable bearings in the side-bar 16, of the carriage 15, upon each side of the press and at each'e nd of the respective cylinders. T he drawings Figs. .6 and 7 illustrate in detail the eccentric upon only one. cylinder and at one end of the press but it will be understood that all the eccentrics are alike. The shafts 2324 of the impression cylinders 2122 are journaled eccentrically in the eccentrics 33 so that by the turning 'of said eccentrics in their journal hearings in the carriage the cylinders are raised and lowered. I 34--35 indicate gears, which are mutilated gears as shown in the figures, secured to the outer surface of the eccentrics 33 in any appropriate manner, as by pin 36. The cylinder-shafts :23-24 pass through the gears 34-35 So as to rotate therein.

37 indicates protecting caps which are secured to theendsof the shafts 2324.

38 indicates rock-shafts which are journaled in the lower ends of the side-bars 16, of carriage 15, uponeach side of the press.

39 indicates rock-arms keyed or otherwise secured to the inner ends of the rock-shafts 38 and carrying at each end a roller 40.

41 indicates segmental rock-arms which are keyed or otherwise secured to theiouter ends of the rock-shafts 38 and are provided at their outer ends with teeth which mesh with the teeth on the gear 35.

It will be obvious that-by rocking the rock-shaft 38 the gears will be rotated'in the one direction or the other causing the rotation of the lower eecentric'33 in its journal bearing in thc carriage and thus causing the raising or lowering of the lower cylin der 22 which, as has beeu said, is eccentrically journaled therein.

42 indicates cams which are secured upon each sideof the framework ot'the press near the feed end thereof and in register with the rollers on rock-arms 3-9 whereby, when thecarriage is reciprocated backward after its printing operation and has reached nearly the end of its movement in this di-,

rection, the rollers 40 riding up cams 42 will rock the rock-shafts 38 in 'a contraclockwise direction, that is to say in the direction indicated'by the arrow in F ig. 2, thus partially'rotating the eccentric 35 in of the type-bed from the cams 42 and 'in register with the rollers 40 whereby, when said carriage is reciprocated in its printing movement, that is from right to left in Figs. 1 and 2, as it reaches the end of the impression, the roller 40 coming in contact with the cam 43 will ride down its cam surface rocking the rock-shafts '38 and rockarms 41 in'the opposite direction from their previous movement thereby partially rotating the cam 35 in the direction indicated by the arrow-in Fig. 3 thus raising the impression cylinder 22 for its return movement.

. 44 indicates rock-shafts journaled in sidebars 16 of the carriage 15 upon each side thereofand midway between the'cylinders 45 indicates rocking-members secured midway of their length upon the outer ends of theshafts 44 and carrying at each end gearteeth 46-47. The gear-teeth 46, upon the lower ends of the rocking-members 45, are adapted to mesh with the gear 35 and the gear-teeth 47 upon the upper end of said arms 45, mesh with the gears 34. I

48 indicates projections upon the rock arms 45 extendingout from the middle portion thereof radially of the shafts 44. v

49 indicates lugs which are pivotally mounted at their inner ends near the outer ends of projections 48, and are perforated to slidingly receive one end of rods 50, the

other end of which is pivoted to brackets 51 on the carriage 15, in line with the center oi shafts 44. i

52 indicates spiral-springs surrounding the rods 50 and bearing at one end against the lugs 49 and at the other end against collars.53,secured on the rods 50.

It will be obvious from the above description that, as -the rock-arms 45 rock in one direction or the other as hereinafter described, the spring-seated rods 50 will pass centers and by the-resilience of springs 52 will prevent the rock-arms from being rocked except as constrained by force greater than the spring and will thus automatically tend to lock the rock-shafts 44, and consequently the impression-cylinders, in either their raised or lowered position as hereinafter described. From the above description it will be seen that as the recipr0- eating carriage approaches the position shown in Fig. 2 near the end of itsbackward movement, after the printing movement, as above described, the rollers 40 rolling up cams 42, rock the rock-shafts 38 and gears 35, and partiall rotate the eccentrics so as to lower thecyhnder 22 into printing position. The rocking of the gears 35 in the irection shown by the arrow in Fig. 2 will rock the rocking-members 45 in the diree tion indicated by the arrow thereon in Fig. 2 thus rocking the gears 34 in the direction indicated by the arrow thereon in Fig. 2, that is to say in thesame direction as gears 35, thus lowering the cylinder 21 in the same manner as cylinder 34 so as to bein 0 erative relation with the upper type-be in the forward or printing movement of the carriage. This same movement will swing the projections 48 upward into the position shown in Fig. 2 causing the rods 50 to pass centers, as above tion the resilience of the spri 1 prevents the rocking of the members 45 in tne opposite direction during the printing mo vement of the cylinders and thereby automatically locking the cylinders in printing position until raised by the stronger force of the cams 43 acting upon rollers 40,

as above described. Itwill also be readily understood that when at the end of the printing movement the parts are brought into the position shown in Fig. 3 and the rock arms 41 and gears 35 are rocked in the direction of the arrow shown in Fig. 3 by the action of cans 43 on rollers 40, as above in the direction indicated by the arrow thereon in Fig. 3, partially rotating the gears 34- in the directionzindicjated by the arrow thereon in Big. 3, partially rotating the eccentrics 33 in which the upper cylinder 21 is mounted, thereby lifting the cylinder 21 for its return nnovement at the same time with the lifting' of c linder, '22", as above described.

By this movement thsr'ods 50 will be rocked downward and caused to pass centers'causing the sp ngs to automatically lock the cylinders infraiscd position until lowered at the end of theirreturn movement for-theirimpression movement, abovedescribed.

the inner part of the press 13. This loopingmechanism may be of any well-known form and character and-is operated by cam 62 mounted on one end of diive-sl aftatii driven by gears (34-55-136. The cam 62 bears upon roller 67 carried on forked-rod 68 which forked-rod. is pivotally connected at its upper end with rock-arm 69 on shaft 70 on which the looping device is carried, the roller being held in contact with the surface of the cam by a suitable spring of the usual character (not shown). As was said the looping mechanism maybe of any well- 65 known character and -operates inthe welldescrlbed, in Will? post.

to describe its opera- 73*indicates a shaft journaled at each end in suitable bearings as" 74 and carrying at the'ends beveledg are 75-76. The bev-' sled-gear 76' meshes with a beveled-gear 77 secured to one end of the shaft 78 suitably a forwarding roller 79 mounted thereon.

The web B, passing from the roller, passes around suitable rollers as 80-.81, into a governor 82 of any warding roll 71, over suitable roller as 84, and thence over roller 85 in the lower end of the looper. From thence it passes under and partially around thence over suitable rollers as 8G--87 88 89, underand partially around impression cylinder 21, thence over suitable rollers as 90, around roller 91 carried on the upper end of the looping device, forwarding roller 92 on press 8 to angle-bars 93 where it is known manner and by any suitable mecha nism brought into register and association with the main web printed on the main press 8.

It will be understood, of course, that the two presses are driven so as to be suitably timed with one another so that the webs may be brought into'proper registry and be associated together to form a single'product. It

press 13 is, of course, provided.- with suit able inking mechanism which may be of any well-known character and which, in order not to encumber the drawings with useless illustration, is omitted. y Y

The operation of the machine will .be understood from the above devices. The, reciprocation of the traveling-bed 10 on the main-press reciprocates the traveling-impression-cylinder carriage 15 of the sup p-lcment press at the same time in the same directionand to the same extent- The parts being in the position shown in Fig. 2 with the imprcssi(in-cylinders lowered into cooperative relation with the type-beds the n'lovement toward the left, in said figure, of the movable typebed l0 causes the movejournaled in the framework 14 and carrying well-known type, thence around suitable rollers as '83, around for- ,ss impression cylinder 22 a; partially around 72, over suitable roller as turned at right angles, and in the wellwill be also understood that the supplement i ment in the Same direction of the carriage 15 with its cylinders which print upon eac side of the web B during this movement, the stoppage oi the web during the printing movement being taken careof by the looping mechanism in the well-known manner. At the end of the printing movement of the traveling-cylinders 218-22 they are lifted as above described. The return movement of the movable type-bed 10 reciprocates the carriage, the cylinders being lifted, as above described, and brings it again into position to again begin its printing movement, the

loopers operatingin the \vellknoWn manner.
