OFFSET MECHANISM FOR PRINTING-MACHINES.
wlbom it may concern:
Be itknown that 1, Oscar Ronsnn, a citi Zen of the United States, residing at New York, county of New York, and State of )Tew York. have invented certain new and useful Improvements in Offset Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
T his invention relates to certain improvements in offset mechanism for printing inachines.
In perfecting the sheets or webs if the previously printed side of the sheet or web is permitted to come directly in contact with covering or blanket of the impression cylinder the ink, if not dry, is liable to set elf upon the blanket so that the succeeding port ions of the webs or the succeeding sheets will be defaced or smudged by the ink thus set off en the blanket.
Various expedients have been employed to prevent offsets, a common construction being an offset web which travels between the perfecting member of the couple and its corresponding impression member, this offset web being unwound from one spindle and rewound upon another spindle. In thus using an offset web, after the first spindle has been emptied and the second spindle filled, it is customary to shift the position of the spindles and the web led again between the couples, the spindle from which itwas first unwound now serving as a rewinding spindle, and the other as the delivery spindle. in such constructions, however, the web is reversed as the position of the spindles is changed so that the side of the web which was next the freshly printed matter during one passage of the web bet-ween the members of the printing couple is next the impression cylinder on the succeeding passage of the web between the members of the printing couple. If, however, the ink which has been taken up by the offset web is notperfectly dry it is liable, when the web is thus reversed, to set off on the blanket, and where repeated set offs occur in the same place the surface of the impression member becomes slightly raised, thus producing a defect in the printing, known as false impression Specification of Letters Patent.
Application filed January 15, 1909.
Patented (Pct. 22,1h12. Serial No. 472,416.
One of the objects of the invention is to provide an improved offset mechanism employing an offset web which is to be repeatedly passed between the members of a printing couple, the construction being such that the side of the web which was next the impression member on one passage of the web be tween the members of the printing couple shall be next the impression cylinder on the succeeding passage.
A further object of the invention is to provide an improved mechanism employing an offset web and unwinding and rewinding saindles in which the position of the spindles may be readily shifted for succeeding passages of the web between the members of the impression couple.
A further object of the invention is to produce an offset mechanism employing a web for winding and rewinding the spindles by which the position of the spindles may be readily and easily shifted for succeeding passages of the web between the impression members of the couple, the mechanism including improved driving and ten sion mechanisms.
\Vith this and other objects not specifically referred to in view, the invention consists in certain constructions, and in certain parts, improvements and combinations as will be hereinafter described and then specifically pointed out.
Referring to the drawings :F igure 1 illustrates in side elevation one embodiment of the invention. Fig. 2 is a plan View of the construction illustrated in Fig. 1, the offset web shown in that figure being, however, omitted. Fig. 3, is a sectional elevation of the construction illustrating certain features not illustrated in Fig. 1. Figs. 4: and 5 are detail views illustrating certain forms of mechanism which may be em ployed.
Referring to the drawings, a rotary printing couple, the printing cylinder of which is marked 1, and the impression cylinder of which is marked 2, is diagrammatically illustrated, said couple serving to perfect a web, indicated at 3. While a rotary printing couple is illustrated, it is to be understood that the invention is not confined to the use of such couples, nor to couples which print upon a Web.
The construction embodying the invention will include an offset web, such web being shown in the drawings, and marked -jt.
In the constructions embodying the invention in its best form there will be employed in connection with this offset web two spin dles, those in the machine illustrated being marked respectively 5 and (5, each of these spindles serving in turn as a receiving; and delivery spindle. hieehanisi'n should be provided for drivingthese spindles when they are in receiving position. This mechanism may vary widely in its construction, but in machines which embody the invention in its best form, a driving mechanism will be provided for each spindle. ln the particular machine shown, the driving mechanism for the spindle includes a pair of cradle rolls, 7, 3 and the driving mechanism for the spindle 6 includes a Sll'lllltll'. pair of cradle rolls 5), 10. These cradle rolls when employed may be driven in any suitable manner. In the construction shown, the rolls 9, 10 are provided with gears 11, 12, these gears being driven by a gear 13. driven by similar gears, these gears being; marked It, 15 see Fig. 2), these gears being in turn driven by a gear 16.
Means will be provided for shifting the spindles so that they may successively occupy receiving and delivery positions. ll hile these means may vary widely. in the best constructions they will be so arranged as to turn the spindles end for end as they are shifted from one position to the other. In the particular machine shown, the shifting means comprises a turn table 17, this table being mounted on a pivot 18 suitably supported in the frame. if desired, in order to reduce the friction, balls 19 may be employed on which the table rests, these balls being supported in a suitable ball-way in the frame. In the particular machine illustrated. the cradle rolls which, as has been indicated, form a part of the driving mechanism for the spindles, are mounted in ti o turn table and, therefore, move with it.
A suitaltile driver will be provided for the driving mechanism wiereby the driving mechanism is operated when the spindles are in receiving position. T his driver may conof a gear 20, this gear being shown in dotted lines in Figs. 1 and 3. This gear 20, when employed, may be driven in any suitable manner, as for instance, by a train of gears leadiu from the impression cylinder as indicated in dotted lines in Fig. 1.
For convenience in enabling the gears 13 and l to be lJI'OllQlli'. readily into mesh with the driver 20, they may he movably mounted on studs. one of which is shown at 21, in Fig. 2, these studs projecting from the frame. The gears 16 .may be mo "ably mounted on the studs in any suitable manner, as by providing the hub of the gear The rolls 7, 8 may be be pulled oil tl with set screws 22 which lock the gears to the studs. The studs may, if desired, be provided with large heads 22-3 to prevent the gears from coming off.
lilachines embodying the invention in its best form will include a tension device that coiiperates with the spindles when they are in delivery position. While this tension device may ary in construction, in the particular machine shown it includes a siaft 24-, this shaft being provided with a grooved drum Cooperating with the drum are blocks 26, these blocks being pivoted on arms 27, in turn pivoted to a cross bar 523. This cross bar is mounted on rods 29 which slide in bearings 30 on a lracket 31, this bracket being also, in the particular ma 'hine shown, provided with a hearing which supports the tension drum shaft The bracket 31 may be formed on or secured to a standard 33 secured. to til. frame.
Suitable means, which n vary in (onstruetion, may be provided, when a tension device including a tension shaft is employed, to couple the shaft to the spindles. In the particular machine shown, the drum shaft 2 1: and. the spindles are provided with interlocking collars ill, 35 (see 1, at. and The collar 35 is secured to the shaft by means of a. feather as so as to slide thereon in order to effect the interlocking. To prevent these collars from becoming se 'iarated, there may be employed a catch pivoted at 38 in a cavity in the collar Elle, this catch being thrown into locking position by a plate spring and engaging with a hooked piece 4-0 secured to the collar 1" headed operating pin it may be provided to disenthe catch from the hook.
in the constructions embodying the invention, means will be provided for adjusting the offset spindles endwise, particularly when in delivery position, so that the. web may run truly to the printing), couple. ll hile this adjusting mechanism when employed may he variously constructed, the ad justment may be well etl'ected by means of the tension mechanism just referred to.
In the particular machine shown. the cross bar 28 is engagedby a screw 4-2 which may, as shown, be provided with a hand wheel 1:9. By turning this screw the bars 29 and the drum shaft may be caused to slide through the bearings and 32. When the drum shaft is locked to one of the spindles it is apparent that the spindle will move with the drum shaft. To prevent the collar 35 from being pulled off the shaft by this adjusting); movement it may be provided with a. set screw, as 44, this screw being arranged to engage in a groove 45 in the shaft 94: so that the collar may have the sliding moven'ient before referred to to engage and disengage it from its companion collar, but will not e shaft when the spindle is adjusted. Each of the spindles may be provided with collars, as 46, secured to the spindles in any suitable manner, as by screws -l-7, which may be loosened to permit the adjustment referred to and afterward tightened to take the strain off the tension mechanism, these collars being arranged to lie close to the bearings which support the spindles.
The tension may be varied in any suit able manner, as for instance by providing the levers 27 with threaded sockets 48 which are engaged by a screw 49, this screw being in turn provided with an operating hand wheel 50. It is apparent that as the web is wound upon the spindle when it is in receiving position the spindle will travel up. When the rewinding operation is completed, however, the spindle will not be clear of the cradle rolls, when the same are employed, and it may not be in proper position to engage with the tension shaft. Further when a roll is empty it will be in a position considerably above its cradle rolls, when this form of driving mechanism is employed. In the particular machine illustrated, mechanism is provided for positioning the rolls to the spindles with respect to their driving mechanism, and also wit-h respect to the tension device shaft. While these means may vary, in the particular machine illustrated, the bearings 51 of the spindle 5 are arranged to slide vertically on guides 52 mounted on the turn table and these bearings have secured to them racks 53 which are engaged by pinions 5%. These pinions are driven through intermediates 55, 56 by gears 57 mounted on a shaft 58 extending across the machine. It will be understood that this shaft is provided with two of these driving gears 57 and the bearings for the spindles at each end of the machine are provided with racks and cooperating pinions. The shaft 58 may be provided with a square end on which a handle 59 may be placed for operating the shaft.
It will be understood that in the machine illustrated the spindle 6 is provided with similar positioning racks, these racks being marked 60. The operating shaft for these racks is below the shaft 58 and is marked 61. The mechanism intermediate the rack 61 is a duplicate of that already described and further description of it is unnecessary. To lock the operating shafts 58 and 61 in position, each of these shafts may be provided with a ratchet wheel 62 arranged to be engaged by a pawl 63. Any suitable web guiding mechanism may be employed. As shown, the turn table is provided with two guide rolls Get, and the bed of the machine is also provided with a suitable web tension roll as 65, this roll being controlled by the usual spring rod construction 66.
The operation of the construction will be readily understood from the foregoing description taken in connection with the drawings. lVhen the offset web has been wound off from the filled spindle and rewound on the other spindle the turn table is given a one-half turn which brings the filled spindle into delivery position. The web is now led from this roll between the members of the printing couple, the turning of the spindles end for end by the turn table serving to cause the web when thus led between the members of the printing couple to be so presented to the couple that the side which was originally next the impression member will be now next it. The driving mechanism for the empty spindle is then connected up with the driver and the tension mechanism is connected to the filled spindle, the positioning device being operated to bring the spindles into their proper positions.
Changes and variations may be made in the constructions by which the invention is carried into effect. The invention is not, therefore, to be limited to the construction hereinbefore described and illustrated.
What is claimed is 1. The combination with a printing couple, of a pair of spindles from one of which an offset web may be unwound and upon the other of which it may be wound, means for transposing the position of the spindles to bring them successively into de livery and receiving positions and turning them end for end, and suitable offset web guides for leading the web between the members of the couple.
