This invention is an improvement in or roller of the press is indicated at which printing cylinder presses. is mounted for rotation upon the frame 11, An object of the invention is to provide a. which frame carries arms 12.

The blocks 26 have threaded stems tion, wherein: p 29 secured thereto which extend through Figure 1 is a top plan view of a portion bridge pieces '30 and are provided with wing of a cylinder press on which the attachment nuts 31'and lock nuts 32, so that the blocks has been mounted, p can be raised and lowered and blocked in 45 Fig. 2 is a vertical section taken substansuch adjusted positions, thus raising or low-.

On the shafts 23 and 27 line 3-3 of Fig. 1, which are those disposed most. adjacent the Fig. 4 is a vertical section taken-on the cylinder 10, there are arranged one or more line 4-4 of Fig. 1, and r sets of perforating or deforming rollers,

Fig. 5 is a perspective view of the attachsuch as is indicated at 33. As shown in Fig. mentl. 3 the upper rollers which are on the shaft 27 Referring to the accompanying drawings constitute the male rollers having projecwherein similar reference characters desigtions thereon so as to perforate the paper, nate similar parts throughout, t e cylinder The lower roller'which is on the shaft 23 may be considered as the female roller and is complementary to the upper roller onthe shaft 27. These rollers are preferably split so that they can be readily removed from the shafts 23 and 27 in order that other types of rollers may replace them.' It will be readily understood that the particular form of the rollers on the shafts 23 and 27 is immaterial and can be varied. While the roller is illustrated as being a perforating roller, other rollers can-be substituted, which will score, slit or crimp. Because of the fact that the rollers are'split, they are'adjustable along the length of their respective shafts, so that the perforating, scoring, slitting or crimping can take place'at any point desirable on the paper delivered from the press.

In order to prevent the paper as it passes through the deforming'rollers on the shafts 23 and 27 from curling around the upper or male roller, there is provided a plurality of guards or strippers. Two rods are mounted between the side members and 21, one of "these rods being arranged forwardly of the shafts 28 and 27, while the other rod is arranged re'arwardly of the shafts 2d and'28. The guards or strippers are indicated at and have their ends fastened to these rods. They have slots formed in them so thatthe blades of the male deforming rollers can pass through them and engage their respective female rollers. It will be readily appreciated that the paper as it is discharged or delivered from the cylinder 10 passes beneath the strippers or guards 35, and the strippers preventit from 'curling'around or rolling around with the male deforming rollers.

When thepaper passes through the deforming rollers, fibers will bestruclr out of its plane or project above surface, and it is desired to smooth down or flatten these rough projecting fibers. Consequently, on the. shafts 24. and 28 there are mounted smoothing rollers 36 and these rollers have smooth or flat. peripheral su-rfaces,'so that when they roll one upon the other with the paper passing between them, the projecting fibers will be flattened and smoothed. The guards or strippers 85 are bifurcated, as indicated at 37, so that the smoothing or flattening v rollers may. engage each other through the strippers. p

Ad acent the side n1einbers21,,the shafts 23, 27, 24 and 28 are provided with gears 38. 'The gears on the shafts 2% and 28 are adaptedto mesh with each other when the blocks 26 are in their lowered positions. In asiinilar, manner the gears 38 onthe shafts 28 and ,2'Z,.are adaptedto mesh when the blocks sesame shaft 27 are in their loweredlpo'sitions. A pinion- 89 is niounted on thesideniember 21 and meshes with the seats-e a es was hi ear a e somewhat wider or thicker than the gear 38 on the shafts 27 and'28. A pinion i is also mounted on the side member 21' and is adapted to mesh withthe gear 38 on the shaft 23. By this gear construction it will be noted that if thepini'on 4 0 is rotated,

the shafts 28 and27 willbe caused to rotate place these rubber belts by coil springs, in-

dicated at 42, which have their ends connected'and thus form an endless belt passing over these pulleys. When the attachmentis applied, it rests on the shafts 14 and 15- with the side members 20 and 21 fitting just within the arms 12. The bushings on the shaft 15 rotate within the slots 22 which receive the shaft 15, and the pinion 40 on the side member 21 meshes with the gear d1 on the shaft 15, so that the various shafts 28, 2d, 27 and 28 are driven by the shaft 15 and also the endless belts 42' are driven by the shaft 1 5. The construction of the parts is so arranged thatthe peripheral speed of the various rollers on. the shafts 24:, 27 and 2 8 is the same speed as that of the endless belts 42, so that there will be no bucklingor tearingof the paper as it passes through the attachment.

From the above described construction, it will be readily appreciated that an attaelr ni'ent for cylindrical presses is provided, wherein the paper which has been printed on the press can be perforated, scored, slit, or crirnped before it is delivered to the jogs ging board, so that all the necessary oper: tions on the paper can be accomplished on the press. Furthermore, if it is not desii' to perforate .or otherwise d'efornr the paper, the blocks 26 can beelevated, raising the shafts 27 and 28 and causing their gears to cease meshing with the gears 38 on the lower shafts; or if desired, the complete attachment can be easilyand quioklyro noved by lifting it from between" the arms 12 as by handles 13. i

It will be understood that Various changes in the detail of construction may bem'a-de without departing from the spirit or scope of the invention as defined by the appended claims.
