PRINTING PRESS.

Application filed. October 2, 1924. Serial No. 741,155.

The invention relates to printing presses,

and more particularly to reversible driving.

mechanism for rotary web presses.

Objects and advantages of the invention 5 will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalitie and combinai tions pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

The invention is directed to improvements in fast rotary web presses of the newspaper or magazine class, whereby a large variety of products may be secured from a press 0t a given construction, including multi-colored products, such as the colored magazines and comic sections of newspapers. The present invention is directed primarily to novel driving mechanism for the various printing couples, each printing couple being individual ly driven from a common driving shaft, vertically disposed at theside' of the press, the general arrangement of such a driving mechanism being shown and described in Patents 700,100 and No. 700,101 to GOSS, dated A 19. 1902.

ly shown and described in Patent No.

528,233 to Michaud dated October 30, 1894. The broad idea of independent reversible gearing or drive for a press of this type is shown and described in Patent Number 555,460 to Michaud, dated Feb; 25, 1896.

. While the present invention is examplarilydisclosed applied to a press of the general Michaud type, and to a verticall disposed shaft drive of the type shown in the Gross patents mentioned, the novel features of my reversible drive mechanism are equally applicable to other general types of presses, and in its more important feature it is to a great degree independent of the type of press in which it may be incorporated and used.

In the present preferred embodiment,

broadly considered, the printing couples are arranged in vertically-disposed series or rows, at either side of an 0 en space, on

which space the impression cy inder of each printing couple faces. A driving shaft for all the printing couples of a vertical series is vertically disposed at one side or end of the series of printing couples, but without being in any essential relation to either the form cylinders '01- impression cylinders of the various printing couples. There are'reversible driving mechanisms between this shaft and each of the printing couples, the entire reversible driving mechanism being preferably on one side of the respective printing couples, without any connections or mehanism extending across the press, and preferably also this reversible driving mechanism is entirely outside of the side frame of the press. p

Meshing with a single continuously rotating bevel gear, which is in fixed position on the vertical shaft, is a likewise con-- tinuously rotating combination gear, comprising a driven bevel gear meshing with accompanying drawings,

i o erative relation at the left hand of Fig. 1.-

direction of rotation selected for the firstanentioned bevel gear and a spur gear fixed to the driven bevel gear and 1'0 tating therewith. liixed to the respective shafts of the form cylinder and impression cylinder of each printing couple, and preferably on extensions of these shafts outside the press side frame, are broadfaced slip gear wheels. These two gears rotate with the respective shafts of the form and impressioncylinders of the printing couple, and are continuously in mesh with each other, but may be alternatively slipped out of mesh with the spur gear of the combination gear just described.

The selective and alternative slipping of these two gears into and out of mesh with the spur gear of the driving combination gear wheel constitutes means for driving the printing couple selectively in either direction. The two cylinders of the printing couple are caused to rotate in. unison by reason of the continuous meshing of the.

broad-faced slip gears mounted on the cylinder shafts.

It will be understood that the foregoing general description of the present preferred embodiment of the invention, and likewise the following full detailed description, is

illustrative and explanatory only, but is not pendent upon the number of webs, the ar-' rangement thereof in the press, and the different printing couples.

The source of web supply is not shown, but a plurality of web rolls are usually in hese sources .of web supply will be adequate in number and may be of any known or suitable form so far as concerns the main features of the present invention.

A pluralit of printing couples are arranged one a ove another, and are shown as four in number, the first couple comprising impression cylinler and form cylinder 2, the second including impression cylinder 3 and form cylinder 4, the third having impression cylinder 5 and form cylinder 6, and the fourth having impression cylinder 7 andform cylinder 8. The inking mechanism for the first printing coupe is indicated diagrammatically by 9, that of the second printing couple by 10, that for the third printing couple by 11 and that for the fourth by 12.

These inking mechanisms are preferably of the usual type, which is mounted on a carriage movable to and fro on the machine frame from operative position with respect to the form or plate cylinder, to a retracted position leaving space for the plates to be changed on the form cylinder and for the inking mechanism to be cleaned, replenished or otherwise attended to.' The inking mechfrom in the press to leave room for the passage of a workman between the two series, and has the impression or blanket cylinders facing on this open space as disclosed in the Michaud patentsalready referred to. The first printing couple in this secondseries comprises an impression cylinder 20 and a form cylinder 21, the second couple com ris in an impression cylinder 22 and a orm cy inder 23, the third couple comprising an impression cylinder 24 and a form cylinder 25 and the fourth couple com. rising an impression cylinder 26 and a orm cylinder 27 The respective inking mechanisms are represented dia rammatically at 28, 29, 30 and 31, each of these being shown in the operative position with respect to its form or plate cylinder.

The general frame structure of the ress comprises a plurality of F-shaped mem rs, each member being two decks high, and having each an upright member 32v and two cross members 33 and 34. The two members constitutin a frame unit are righthanded and left-handed with respect to each other, and their cross reaches 33 and 34 are bolted together at 35 and 36. A similar construction and arrangement may be used and is shown for each pair of printing couples and each pair of dec A plurality of bracing or cross pieces 37 may be employed between the di erent press units.

Any suitable folding mechanisms may be employed, as may be found advisable or de sirable with the particular type or construction of press wherein the invention is embodied, and in the drawings, a pair of longitudinally disposed single formers 39 and 40 are shown with cooperating cross-folders 41 and 42. It will be understood, however, that these-may be selected and varied as desired. A slitter 43 for centrally or other wise slitting the web is shown diagrammatically, a turner bar or system of turner bars 44 being also similarly shown. 1

Referring now more particularly to the details of the press drive. a driving shaft 54 is shown arranged longitudinally beneath and alongside the press, and this maybe provided with any usual or suitable throwout clutchfreversible gearing drive, or any other Fixed on shaft 54 is a. bevel gear wheel 55, which meshes with a bevel gear wheel 56,

fixed on a vertically-disposed driving shaft 57. This shaft has individual driving connection with each printing couple, but is not in any essential relation to the shaft of either the impression cylinders 01' the plate cylinders, as the shaft does not drive direct- 1y onto the cylinders 'of the printing couples, but the direction-reversing gearing is interposed between the gear wheels on this shaft and the cylinders of the printing couple. Shaft 57 is supported in bearings 58, 59, 60. 61 and 62, carried on the side frame of the press, and has fixed thereto single bevel gears 63, 64, and 66, one for each printing couple.

There is a reversible drive for each of the printing couples from the beveled gears 63. 64:, 65 and 66, and the description of one of these reversible driving mechanisms will sufiice for all of them.

Meshing with one of the bevel gears, say car 63 (Figs. 3, 4 and 5), is a bevel gear 6 mounted to rotate freely upon a shaft 77,

which shaft is fixed within and supported by a bearing 78, integral with and extending outwardly from the side frames 79 of the press. This shaft is held in position by any suitable means, and as shown, a washer 80 is on the inside end of shaft 77, and a retaining nut 81 is threaded on the end of the shaft, the washer and nut bearing on a boss 82 on the inside of the press frame. A spur gear wheel 86 is fixed to rotate with the bevel gear wheel 7 6, and as embodied these two constitute a combination driving gear. As shown. this spur gear wheel 86 is mounted to rotate freely on the shaft 77, and the bevel gear wheel 76 is fixed to the side face thereof by screw bolts 87 and 88. Thus the combination gear wheel rotates continuously with the bevel gear wheel 63 on shaft 57.

In the particular printing couple, the inipression cylinder 89 has one end of its shaft 90 journaled in a. bearing 91 inthe side frame of the press, the shaft extending yond the bearing and exteriorly from the side frame. A broad-faced spur-gear wheel 92 is mounted on the shaft 90 to rotate with but to slide along the shaft. For this purpose shaft 90 is provided with a spline or feather 93, and a clamping screw 94 in the hub 95 of the gear wheel serves to hold the gear wheel 92 in the desired position. A washer 96 and a nut 97, screw-threaded on desired or convenient connection.

the end of the shaft, retain the gear wheel on the shaft.

The form cylinder 99 cooperates with the impression cylinder 89, and one end of its shaft 100 is journaled at 101 in the press side frame, the shaft 100 likewise extending exteriorly beyond the bearing and side frame. A broad-faced spur-gear wheel 102 is mounted upon this exterior end of the shaft 100, to rotate therewith but to slide therealongf Gear wheel 102 is mounted on shaft 100 by means of a spline or feather 103, and a clamping screw 104 in the hub 105 of the gear Wheel serves to hold the gear wheel in either desired position. A washer 106 is held in place by nut 107 screwthreaded on the end of the shaft 100 to keep the gear Wheel on the shaft. This slip gear wheel 102 is continuously in-mesh with the slip gear wheel 92 on the shaft of the other cylinder, but they are relatively slidable while so intermeshing.

The spur gear 86 of the combination gear is continuously driven in one direction through the bevel gear 63 on the shaft 57 driving the bevel gear 76 of the combination. In Fig. 3, spur gear 102 is slipped out to the exterior position on the shaft 100 whereby it is in mesh with spur gear 86 of said combination gear. Due to theinbroad faces, gear wheels 102'and 92 are always in mesh with each other, and in this position, gear wheel 92 is driven from gear wheel 102, and the cylinders 88 and 99 are rotated together in a desired direction.

In Fig. 5 the-reverse relation of the driving gears is shown, as in this figure gear wheel 92 has been slipped into mesh with the spur gear wheel 86 of the combination gear, and gear wheel 102 has been slipped out of meshwith spur gear wheel 86, but the two broadfaced gear wheels 92 and 102,

it will be recalled, are continuously in mesh.

The combination gear wheel is now driving to gear wheel. 92 in the opposite direction from that in which it drove gear wheel 102, thus rotating the printing couple in the opposite direction. The gear wheels'92 and 102 being in mesh, the form cylinder and impression cylinder are now rotated together in the opposite direction.

From all the foregoing it will be understood that a mechanism has been provided constituting an exemplary embodiment of the invention, and realizing the objects and advantages herein set forth, together with other objects and advantages. llt will be understood further that departures may be made from the exact mechanism as shown and described, within the scope of the ac companying claims, without departing from the principles of the invention and without sacrificing its chief advantages.
