PRINTING I'RESS.

Application filed August 20, 1924. Serial No. 733,115.

The invention relates to printing presses, and more particularly to reversible driving mechanism for rotary web presses.

Objects and advantages of the invent1on 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 instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinat1ons 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 inventron.

Of the drawings Fig. l is a side elevation, partially diagrammatic, of a press constructed in accordance with the invention;

Fig. 2 is a diagrammatic end elevation, looking at Fig; 1 from the right;

Fig. 3 is a fragmentary detail, in elevation, greatly enlarged, of the lower central part of Fig. 1;

Fig. 5 is a diagrammatic perspective, showing one relation of the driving mechanism for driving in one direction; and f Fig. 6 is a similar; view showing themechanism arranged to drive the printing cylinders in the opposite direction.

The invention is directed to improvements in fast rotary web presses of the newspaper or magazine class whereby a. large variety of products maybe secured from a press of a given construction, including multi-colored products, such as the colored magazines and comic sections of newspapers. invention is directed primarily to novel. driving mechanism for the various printing couples, each printing couple being individually driven from a common driving shaft, ve tically, disposed at the side of the press, the general arrangement of such a driving mechanism being shown and de-.

The present scribed in Patents No. 700,100 and N o. 700,- 101 to Goss, dated Aug. 10, 1902.

The invention is shown exemplarily embodied herein in that type of rotary web press wherein two vertically-disposed series or groups of printing couples are arranged at either side of an openspace, with the impression or bl'anket cylinders next to the open space, on either side, so that each of the impression or blanket cylinders may be readily accessible for changing the blanket, making ready, etc., which type of machine is broadly 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.

W'hile the present invention isexemplarily disclosed appliedto a press of the general Michaud type, and to a vertically disposed shaft drive of the type shown in the G055 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 open space, on which space the impression cylinder of each printing couple faces. ..-\'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 or impression cylinders of the various printing couples. Fixed'on this vertical driving shaft is a beveled gear'for each printing couple, and meshing therewith is a continuously inter-meshing beveled gear.

This latter beveled gear is in driving relation with a spur gear, preferably at the opinder and the other on the shaft of the impression cylinder, these two gear Wheels being alternatively and selectively movable or otherwise attended to. The inking mechinto and out of mesh with the driving gear wheel which in turn is driven by the bevel gearing already described.

The selective-and alternative slipping of these two gears into-and out of mesh with the driving gear constitutes means for driving the printing couples selectively in either direction. The two cylinders of the printing couple are caused to rotate inuniso'n by means of two continuously meshing gears,

one on the shaft of the form cylinder and the other on the shaft of the impression'cylinder. v

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 restrictive of the invention. It will be understood further that certain features, objects and advantages of the invention Will be primarilyset forth in connection with the ensuing detailed description.

Referring now in detail to the embodiment, illustrated ,by way of example in the accompanying drawings, the invention is shown applied to a four-deck newspaper press adapted to perfect a single web in a plurality of colors, or to print a plurality of webs on one side, or to perfect them in a single color, or in a plurality of colors, dependent upon the number of webs, the arrangement thereof in the press, and the direction of rotation selected for different printing couples.

The source of web supply is not showh,

'but a plurality or web rolls are usually in operative relation at the left hand of Fig.

1. These sources pf web supply will be adequate in number and may be of any known or suitable form sofa'r as concerns .the main features of the present invention.

, A p'luralit of printing couples are arranged one a ove another, and are shown as four-in number, the first couple comprising impression cylinder 1 andform 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 and form cylinder 8. The inking mechanism for the firstrinting couple is indicated diagrammatica ly by 9, that of the second printing couple" by 10, that for. the third I printing couple by 11 and that for the fourth by These inking mechanisms are preferably ofthe usual type, which is mounted on a carriagemovable to and fro on the machine frame from operative position wlth 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 "-nking'mechanism to'be cleaned, replenished anism for the second printing couple in Fig.

for the other printing couples are shown in operative relation with their respective plate cylinders. So .far as, concerns the general features of the present invention, the particular fornrof inking mechanism is immaterial. i Y

The second series or group of verticallyd'isposed printing couples is generally similar to the first, and is spaced away therefrom 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 patents already referred to. The first printing couple in this second series comprises an impression cylinder 20 and a form cylinder 21, the ,second couple comprising an in'ipression cylinder 22 and a form cylinder 23, the third .couple compris ing an impression cylinder 24 and a form cylinder 25 and the fourth couple comprising an in'lpression cylinder 26 anda form cylinder 27. The respective inking mechanisms are represented diagrammatically at 28, 29, 30 and 3t, each of these being shown in the operative position with respect to its form or plate cylinder.

The general frame structure of the press comprises a plurality of F-shaped members, each member being two decks high, and having each an upright member 32 and two cross members and 34. The two members constituting 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 folders 41 and. 42. It will'be understood,-

however, that these may be selected and varied as desired. A slitter 43 for centrally or otherwise slitting the web is shown dlagrammatically, a turner bar or system of'- turner bars 44 being also similarly shown.

details of thepress drive, a driving shaft 54 is shown arranged longitudinally beneath v and alongside. the press, and this ,may be provided with any usual or suitable throw- Referring now more particularly to the out clutch, ]revers1ble gearing drive, or any other. desired 'or convenient connection. Fixed on shaft 54 Is a bevel gear wheel Shaft 57 is supported in bearings 58, 59,

60, 61 and 62, carried on the side frame ofthe press, and has fixed thereto single bevel gears 63, 64, 65 and 66, one for each printing couple. Meshing with these bevel gear wheels, are corresponding bevel gears 68, 69, and 71, which are in turn fixed to corresponding transversely-disposedshafts, journaled in the machine frame. The bevel gears on the vertically disposed driving shaft 57 and the bevel gears driven thereby are "continuously in mesh; 1

Referring especially to Figs. '3 and 4, Which-may be considered exemplary of the mechanism for each of the printing couples, the bevel gear wheel 63 is in fixed position upon the shaft 57, and is continually in mesh. with the bevel, gear 68, likewise already referred to; Bevel gear wheel 68 is fixed on a shaft 90, having bearings 91and 92 in the side frames of the press, the shaft extending across the press parallel to the shafts of the form cylinder and impression cylinder of the particular printing couple. On the opposite side of the press shaft projects beyond the side frame, and fixed thereon is a spur gear wheel 93.

The shaft '94 of the impression cylinder 1 has bearings 95 and 96 in the side frames of the press.

. cylinder 2 has bearings 98 and 99 in the side frames of the press. Means are provided for insuring the plate and impression cylinders rotating in unison at all times,

and for. this purpose, aspur gear 100 is fixed to shaft 94 of the impression cylinder, and a spur gear 101 is fixed on the shaft ,97 of the late cylinder 2, these two gears being continuously in mesh.

In the embodied form of selective reversible drive, there is mounted on the shaft 94 of the impression cylinder, preferably exterior to the side frame of the press and at the opposite side a spur gear 106. -G6Z1I 106 is fixed to shaft 94 to always rotate therewith, but is slidable along the shaft into and out ofmesh with thespur gear 93 on'the shaft 90. For thispurpose gear 106 has a clamping screw '107 in thehub, and it is mounted on shaft 94 bymeans of a spline or'feather 108 fixed to the shaft. Likewise, a spur gear 109 is mounted in like position on shaft 97 of the plate cylinder The shaft 97 of the form 2, to always rotate therewith, but is also slidable into and out of mesh with the gear .wheel 93.v For this purpose the hub of gear 109 is'provided with a clamping screw 110,

and the gear wheel is mounted on the shaft 97 by a spline or feather 111 fixed to the shai' Thus by alternatively and selectively slidinggear ' wheels 106 and 109 into and out of mesh with gear wheel 93, the printing couple is driven in either direction as desired, the gears 100 and 101 always insuring the cylinders of the printing couple rotatin togetherin unison, and the bevel gear rive from the general shaft being always in J mesh. 3 p

In the perspective diagram of Figs. 5 and 6, the relations of the gear wheels, driving in either direction is shown, the arrows on the wheels showing the direction of rotation inboth cases. The printing cylinders and many other parts are omitted from these diagrams. In Fig.5 gear wheel 106 is slipped, and gears 93 and 109-are in mesh,

and drive theprinting couple in one direction, as indicated, by the arrows on gears 100 and 101. In Fig. 6-gear wheel 109 is slipped, and gears 93and 106 are in mesh, driving the printing couple in the opposite direction, as indicated by the arrows on gears 100 and 101.

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. It will be understood further that departures may be made from the exact mechanism as shown and described, within the scope of the accompanying claims, without departing from the principles of theinvention and without sacrificin its chief advantages.
