To aZZ whom it may concern:

Be it known that I, Farmers MEISEL, a citizen of the United States, residing at Boston,

perfecting printing-machine embodying my improvements. Fig. 2 is an enlarged detail of the adjustable carriages which support the paper feeding and cutting mechanism. Fig. 3 is a transverse vertical section on the line 3 3 of Fig. 2, the feeding-belts being removed. Fig. 4 is an elevation of a portion of the paper-feeding belt, and Fig. 5 is a transverse section of the same. Fig. 6 is a transverse vertical section on the line 6 6 of Fig. 2, the feeding-belts being removed. Fig. 7 is an enlarged side elevation, partly in section, of one of the tape-carrying devices of the second impressioncylinder. Fig. 8 is an end elevation of the tape-carrying devices, one of which is shown in Fig. 7. Fig. 9 is an enlarged sectional detail of the first impression-cylinder, showing myimproved shoo-fly mechanism. Fig. 10 is an enlarged sectional elevation of the first impression-cylinder and parts immediately connected therewith. Fig. 11 isa vertical section on the line 11 11 of Fig. 10 looking toward the left. Fig. 12 is an enlarged side elevation of the cutter-cylinders.

In the said drawings, A represents the framework of the machine, in suitable bearings in which runs the driving-shaft a, car- I rying a gear I), which meshes with the gear 0 V on the shaft of the first plate-cylinder B, said gear 0 meshing with the gear cl on the shaft of the first impression'cylinder D, the gear (I in turn meshing with the gear 6 on the shaft of the second impression-cylinder E, and said gear 6 meshing with the gear f on the shaft of the second plate-cylinder G, motion being thus communicated to said printingcylin- I ders and by means of other suitable gears td other rolls and moving parts of the machine to be hereinafter described.

The web 9 of paper to be cut into sheets is drawn from a roll 25, which is mounted on a shaft supported in bearings in the framework A, said web passing under and over suitable guide-rolls and being unwound from the roll 25 by a pair of feed and drawing rolls 26 27, journaled in a carriage I-I, sliding on ways 28 on opposite sides of the framework and 0p erated by a rack and pinion 29 30, as shown in Figs. 1 and 2, whereby the carriage maybe adjusted to vary its distance from the printing-cylinders. In the carriage H are jour= naled the shafts of the cutter-cylinders 31 32, having a surface velocity greater than that of the feed-rolls, the upper cylinder being pro: vided with a projecting cutter-blade 125 and the lower one with a groove 126, admitting the said blade, the cutter severing the sheet from the web at the instant before it is seized by the grippers 20, Figs. 1, 9, andll, of the impression-cylinder D, and by adjusting the carriage H as described the cutters can be placed at a distance from the grippers 20 equal to the required length of the sheet to be severed from the web or the carriage moved backward far enough to enable the operator to have convenient access to the front pair of printing-cylinders.

To the upper cylinder 31 in front of the cutter-blade-125 is secured a flat spring 127, a part of the outer surface of which nearest to the cutter-blade is covered with a piece of elastic material 128, preferably felt or rubber, which serves to press the web of paper onto the surface of the lower cutter-cylinder 32 and hold it stretched, thereby preventing the paper from being forced down into the groove 126. This spring must be of such strength only as to allow it to slip on the paper without tearing it.

At a short distance in the rear of the cutter-blade 125 is a brush 129, projecting from the surface of the upper cutter-cylinder 31, which brush serves to hold the front edge of the web down upon the lower cutter-cylinder and prevent said edge from being carried upward by the cutter-blade as the cylinder 31 revolves.

K is an auxiliary carriage, which slides on inclined ways 33 on the main carriage H. To the carriage K is secured a table 35, Figs. 1 and 2, to which is fastened one end of a piece or band of smooth-surfaced flexible material 36, which is also stretched over a transverse bar 37, secured to the carriage H, beneath which bar it is wound up on a roll 38, whereby as the carriage K is adjusted it is kept tightly stretched, as desired, to form a stationary support for the sheet as it is carried forward to the printing-cylinders. The front end of the table 35 serves to support and guide the sheet of paper to the cylinder D, so that it will be seized by its grippers 20, and at the same time keeps the front edge of the sheet away from the plate-cylinder B. The auxiliary carriage K is operated by means of a rack and pinion 22 23, whereby it may be adjusted on the main carriage H to keep the front edge of the table 35 always in the same position close to the impression-cylinder D as the position of the main carriage H is changed to vary the distance of the feed-rolls and cutters from said impression-cylinder D as is necessary for sheets of different lengths or sizes, it being obvious that the front edge of the table 35 must always be in'the same position with respect to the printing-cylinders without regard to the distance therefrom of the cutters, the position of which will vary according to the length of the sheets being out. For instance, when shorter sheets are to be cut the auxiliary carriage remains stationary, while the main carriage is moved nearer to the printing-cylinders by means of the rack and pinion 29 30, as before described. When the carriage K is adjusted on the carriage H, the roll 38 is revolved by means of a suitable handle (not shown) to wind up or unwind the flexible support 36, as may be required, to keep it properly stretched between its two points of attachment.

Directly over the sheet-support 36 are arranged a pair of endless paper-feeding belts 40, to each of which is preferably attached a strip of pliable material 41, Figs. 4 and 5, of less width than the belt and extending from one end to the other of the same, said strip having a rough surface-as, for instance, plush. These belts are supported by and run upon rolls 42, 43, 44, and 45, the shafts of the rolls 42 and 43 being provided with gears, which mesh with an intermediate gear 21, meshing with and driven by the gear 61 of the impression-cylinder D, the belt being thereby driven positively at the same surface speed as the printing-cylinders. The shafts of the rolls 42, 43, and 44 run in bearings in the carriage K, while the shaft of the rolls 45 runs in bearings in the main carriage H. The belts 40 run over the rolls 42, 43, 44, and 45, with the rough surfaces of the strips 41 in contact with the upper surface of the paper, which is thus by the frictional contact of said strips 41 carried over the surface of the flexible support 36 to the grippers of the cylinder D, and by this device I am enabled to dispense with the usual tapes above and below the paper, which are objectionable on account of the difficulty of preventing the paper from being wrinkled thereby. A further objection to the tapes is that they are liable, if broken while the machine is in motion, to be carried between the plate and impression cylinders, thereby destroying such plates as they come into contact with. On the shaft upon which the rolls 44 revolve are pivoted arms 46 47, carrying on their outer ends belt-tightening rolls 48 49, the latter being each provided with a groove 50, Fig. 3, to receive the narrow strip 41, the plush surface of which is thus prevented from being flattened down or injured by contact with said rolls 49. By adjusting the arms 46 47 any slackness of the belts 40 produced by the forward adjustment of the carriage H or otherwise can be taken up to render them at all times sufficiently tight to act on the sheet as required. After the carriage H has been adjusted by means of its rack and pinion it is securely held by means of clamping-bars 55, one on each side, which are hung on an eccentric shaft 56, each bar having a lip or projection 39, Fig. 6, at its lower end which engages a rib 57 on the framework A, whereby as the shaft 56 is turned by means of a suitable handle 33, Fig. 6, the carriage will be securely clamped in place as desired. The length of the sheet 19, Fig. 2, severed from the web by the cutters can be varied by changing the surface velocity of the feed-rolls with relation to that of the rotary cutters, which can be effected in a well-known manner by the employment of a changewheel, as described in Letters Patent No. 601,200, granted to me March 22, 1898. Instead of the flexible band 36 endless belts, tapes, or an apron having a surface velocity equal to that of the impression-cylinder may be employed. I prefer, however, to use the flexible band 36, as it prevents the sheet from wrinkling and renders the mechanism much simpler and cheaper to construct.

As soon as the sheet is seized by the grippers 20 of the first impression-cylinder D, said grippers having been opened and closed for this purpose by wellknown mechanism hereinafter described, it is carried between the impression-cylinder D and the first platecylinder B, receiving an impression therefrom, and thence between the cylinder D and rolls 15, one of which is shown in Figs. 1 and 9, after which it is carried by mechanism, to be hereinafter described, to and between the second or perfecting pair of plate and impression cylinders GE, and thence by means of tapes over the offset web 71 to the accumulating-cylinder M, which is provided wit grippers f and may be of any suitable or approved construction. The grippers 20 of the cylinder D are mounted on a rock-shaft 60, Fig. 10, journaled in said cylinder, to one end of which shaft, outside the said cylinder, is secured a pinion 61, which meshes with a sector-gear 62 at the end of a lever 63, pivoted at 64 to the end of the cylinder D, said lever carrying a roll 68, (shown in Fig. 10 and dotted in Fig. 11,) which is acted upon bya canigroove 34 in a stationary disk 69, secured to the framework A, (see Fig. 10,) whereby the desired movements are imparted to the grippers 20 as the cylinder is revolved. As soon as the front or leading end of the printed sheet 19, Fig. 9, has been released by the grippers it is pushed out from the surface of the cylinder D by a series of shoo fly pusher-plates 71, which pass through a long narrow slot 72 in the gripper-bar 73, the inner ends of the shoo-fly plates being adjust- V ably secured between the two members of a clamping-bar 74, bolted to a bar 66, to the opposite ends of which are pivot-ed two links 75, pivoted to arms 76 on a rock-shaft 77, having its bearings in the ends of the cylinder, said shaft also carrying outside the cylinder D an arm 78, which is provided at its end with a roll fitting within a cam-groove 79 in a disk 80, secured to the framework. The shoo-fiy plates, of which there may be any suitable number, are thrust forward just after the grippers have released the sheet and serve to push the leading edge of the sheet outward, so that it will pass over a series of pointed guides 81 and between the oifset web it of the second impression-cylinder and the paper-carrying tapes m, to be presently described. Each shoo-fly plate has a notch 12, which enables it to straddle and pass the adjacent guide 81 as the cylinder D revolves in such manner as to push out the sheet and at the same time prevent it from being obstructed by the guide in its passage thereover. The grippers 20 seize the sheet at the moment it is severed by the cutters and release it just before it reaches the guides 81, the rolls 15 preventing the sheet from dropping back after such release and before it is taken by the tapes m. The tapes m, Figs. 7 and 9, of the second impression-cylinder E are each supported by a series of rolls S5 86 87, Fig. 7, the rolls 85 and 86 being carried by frames or brackets S, adjustably secured by bolts 88 and nuts 89 in a longitudinal groove 90, formed in a cross-bar or support 91, extending between the sides of the frameworkA. The entire series of rolls 87 are mounted on and rotated by the shaft n, which is provided at one end with a gear 58, Figs. 1 and S, which is engaged by an intermediate gear 59, meshing with and driven by the gearfon the shaft of the upper plate-cylinder G, the tapes having the same speed as the surface of said cylinder. Each roll 87 slides on but rotates with the-shaft n and is embraced bya fork 130 on the bracket S, whereby as the several brackets are adjusted on the cross-bar 91 the rolls will be carried with them. The lower rolls 85 are located close to the guides 81, which are formed at the ends of arms 51, which form the lower ends of the brackets S, and the upper rolls 86 are mounted in arms (55, each forming a portion of one of the brackets S,

said arms being made detachable, so that they can be removed when it becomes necessary to take out the tape-supporting mechanism, which could not otherwise be accomplished for want of space between the cylinders 'D G. Each of the tapes m is tightened, if loose, by means of a roll W bearing againstit, as shown in Fig. 7, said tightening-roll being mounted on an eccentric stud 84E, projecting from an arm 93, pivoted on a hub 83, Fig. 8, projecting from the bracket S, said arm 93 being adjustably secured at its lower end by means of nuts 82 to the threaded end of a rod 94, the opposite end of which is connected to a shaft 95, eccentrically mounted in the sides of the framework A and provided with a handle 96, Fig. 8, by the turning of which the entire series of tapes m may be simultaneously tightened or loosened, as required, while each tape m may be individually tightened or loosened by means of the nuts .82 or the eccentric stud 84. By moving the brackets S longitudinally upon the cross-bar 91, as described, the tapes and their supporting-pulleys may be adjusted at suitable distances apart for sheets of any desired width.

The offset web It is unwound from the dispensingroll T, Fig. 1, and thence passes over removable guide-rolls 98 99 to and around the second impression-cylinder E, thence over rolls 100 101 102 103 105 to the roll V, upon which itis rewound in the usual manner. The dispensing-roll T is arranged, as shown, at a sufficient distance from the second impression-cylinder E to enable the offset web Ft after the guide-rolls 98 99 have been removed to be lowered down, as shown by dotted lines in Fig. 1, away from the bottom of said cyl inder E, whereby the operator is afforded convenient access to said cylinder to make ready the same or for other purposesan important advantage in printing-machines of this description.

After passing between the printing-cylinders E G the printed sheet is carried forward by the offset web h and tapes I), which run over pulleys o d, the pulleys 0 being mounted on arms 6', secured to a shaft f, and thepulleys (1 being mounted on a shaft g, which. carries a gear 106, driven by intermediate gears 107 108, the latter meshing with the gear 109 on the shaft of the accumulating-cylinder M.

To prevent the sheet from following the offset web it as the latter passes over the guideroll 100, I employ a rotary brush 110, Fig. 1, the shaft of which is provided with a gear 112, driven by the gear 109 of the accumulatingcylinder M through the medium of an inter mediate gear 114, said brush-revolving in the direction of the arrow, whereby it is caused to assist the tapes 1] in carrying the printed sheet to the accumulating-cylinder.

A removable board 120, Fig. 1, extends across the lower portion of the machine at the bottom of the opening 121, where it is supported by resting on the sides of the framework. This board 120 forms a platform for the operator to stand upon while working on the second impression-cylinder and serves to protect that portion of the oifset web which lies beneath it.
