ROTARY SHEET-PRINTING M'ACHINE.

Specification of Letters Patent.

Application filed July 9, 1912. Serial No. 708,464.

Zo all whom it may concern:

Be it known that I, RALPH 0.. SEYMOUR, a citizen of the United States, residing at- Larchmont, county of Westchester, and State of New York, have invented certain new and useful Improvements in Rotary Sheet-Printing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the-same.

This invention relates to improvements in rotary sheet printing machines.

In rotary machines printing on sheets and which employ two printing couples for delivering successive print-ings on the same side of the sheet, it is necessary to transfer the sheet from the first to'the second couple in such a way that the side which has been printed by the first couple will be in position to receive the impression from the'print-ing member of the second couple. The transfer cylinder is a common sheet transferring agency and has a marked advantage in that it handles the sheet without losing control of it and thus interfering with the register, but its employment in a machine 'such as has been described: where it is .located between the couples is objectionable, because it' interferes'with proper access to the printing cylinders for the pur ose of making ready.

It is one of the ob ects of this invention to produce an improved sheet printing machine having a plurality of couples adapted to deliver successive impressions on the same side of the sheet, and a transfer cylinder located between the printing members of the couples, the cylinder being mounted in such a way that it may be moved from between the couples to permit access thereto for the purpose of making ready.

A further object of the invention is to produce an improved printing machine having a plurality of printing couples adapted to deliver successive printings on the same side of the sheet and having a transfer cylinder located between the couples, the transfer cylinder being mounted in such a way that it may be moved out from between the couples for the purpose of making ready, this movement being effected without disturbing the driving relation of the couples.

with these 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 hereinafterfully'described and then specifically pointed out.

In the accompanying drawings :Figure 1 is a diagrammatic side elevation of a printing machine constructed in accordance with the invention. Fig. 2 is a sectional elevation. Figs. 3 and 4 are detail views.

Referring to the drawings which illustrate one embodiment of the invention, 1 indicates the printing cylinder and 2 the impression cylinder of a rotary printing couple. The cylinder 1 is mounted on a shaft 3 and is inked by the. usual inking mechanism, indicated at 4. The cylinder 2 is mounted on the shaft 5.. The path of the entering sheet is indicated by the broken line 6. The printing cylinder of the second couple is indicated at 7, this cylinder being 'mounted on a shaft 8 and being inked by the usual mechanism, marked 9. The impression cylinder of this couple is indicated at 1.0, this cylinder being mounted on a shaft 11. The sheets after printing may be taken from the cylinder 10 by the usual delivery cylinder 12 mounted on a shaft/13,

. andmay be'delivered fiat in any suitable way, .as by tapes, indicated at 14. In machines. embodying the invention means will be provided for driving the cylinders of the couples in unison. While these means may be varied, in the particular construction illustrated, the shaft 13, which. for the purpose of this specification may be considered the driving shaft of the machine, is provided with a gear 15 which meshes with an intermediate 16, this intermediate meshing in turn with another intermediate 17 The intermediate 17'meshes with a shaft 5.

In machines embodying the invention the sheets will be transferred after being printed by one couple, to the next couple by a transfer cylinder, as 19, which will be mounted in such a way that it may be moved from between the couples to permit access thereto for making ready. TheQmeans for mounting the transfer cylinder so that itv may be moved as described may be varied within wide limits. In the best constructions embodying the invention, however, this transfer cylinder will be mounted in such a way that its movement may be effected without disturbing the driving relation either of the couples or of the transfer cylinder itself. It will be understood that the cylinders 2,

gear 18 on the 10 and the transfer cylinder 19 will be provided with sheet taking devices, such, for instance, as the grippers indicated in the drawings. In the particular construction illustrated, the cylinder 19 is mounted on a shaft 20, this shaft being supported in arms 21 swung on the shaft 5. There will be one of these arms 21 on each side of the machine and they are provided with sectors 22 which mesh with pmions 23 mounted on a shaft 2& extending across the machine from side to side. These shafts 24: are further provided with worm gears 25 meshing with worms 26 on vertical shafts 27 These vertical shafts carry bevel gears 28 which mesh with similar bevel gears 29 on an operating shaft 30extending across the machine from side to side. This shaft may be provided with squared end, as indicated at 31, for the attachment of a suitable turning means, such as a crank, The shaft 20 is provided with a gear 32 which meshes with agear 33 on the shaft 5 of the cylinder 2.

It will beimderstood that by the mechanism described the transfer cylinder 19 can be moved away from between the cylinders 2 and 10 to permit access to these cylinders for the purpose of making ready. Further, the movement of the cylinder 19 is effected without disturbing the relation of its sheet taking devices with respect to the sheet taking devices of the cylinders 2 and 10, that is to say, as the cylinder 19 moves, its gear 32 rolls on the gear 33 so that when the cylinder 19 is moved back into its operative position its sheet taking devices are in the same relation with respect to the sheet taking devices of the other cylinders that they were before the cylinder was moved. Further, if it be necessary, as it frequently is, to turn the cylinders over while the cylinder 19 is moved out from between the cylinders 2 and 10, this can be accomplished without distnrbing the relation of the sheet taking devices of the several cylinders because when any cylinder is turned over the other cylinders have a corresponding movement.

I It will be understood that changes and variations may be made in the construction by which the invention claimed is carried into efiect, fore, is not to be confined to the particular shaft of one of the members 0 roaster The invention claimed, thereconstruction herein described and illustrated in the accompanying drawings.

What is claimed is 1. The combination with a pair of rotary printing couples arranged to deliver successive printings on the same side of the sheet, of a transfer cylinder located between the couples, means for driving the transfer cylinder in a direction opposite to that of the impression cylinder of the first printing cou- 'ple, means for driving the printing couples in unison, and means for moving the transfer cylinder from between the couples while maintaining the driving relation of the couples and of the transfer cylinder.

2. The combination with a pair of rotary printing couples arranged to deliver successive printings on the same side of the sheet, of a transfer cylinder located between the couples, gearing for driving the members of the couples in unison, a gear' on the shaft of one of the members of one of the printing couples, an intermeshing gear on the shaft of the transfer cylinder, and means for moving the trans-fer cylinder from between the couples without interrupting the driving relation between its gear and the gear that drives it. i i

3. The combination with a pair of printing couples arranged to deliver successive printings on the same side of the sheet, of a transfer cylinder located between the couples, gearing for driving the members of the couples in unison, a driving car on the one of the couples, an intermeshing gear on the shaft of the transfer cylinder, and arms in which the transfer cylinder is mounted, said arms being pivoted on the shaft which carries the gear for driving the transfer cylinder gear.

- In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
