FOLDING MECHANISM.

Specification of Letters Patent.

Patented Jan.'1'7, 1911.

To (it! whom it may concern: I

lie it known that I, Osou: Ronsnlv, a cit-i zen of the UnitedSt atcspresiding at New Yo1'k,-cou1ity of New York, and State of New York, have invented certain new and useful Improvements in Folding Mechanisms, fully described and represented in the following specitiation and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in folding mechanisms for high speed rotary web printing machines.

it is common in the art and in that class of machin'cs known as straight line machines to run a multiple width web after it leaves the printing couples direct, that is, in a straight; line andwitholusidewise deflection, to folding mechanisms of the longitunal type, these mechanisms operating to produce tolds'in the webs which are parallel with the run of the webs. As each of these folding mechanisms folds its web loiigitmlinally out of the path in which the web is traveling, .no di'llicnlty exists in properly locating the folding mechzu'iisms adjoining each other, because there is plenty of rooi'n, owing to the peculiar characteristics of the folders, to dispose the operating mechanisms. When, however, it was desired to give the webs a fold which is transverse to the path ill-which the webs are running it has been customary to use turner bars by which the webs were deflected .sidewisc, this conetruction' affording the necessary space for installing the folding devices and their operating mechanisms. It; will be understood that the folding mechanisms for high speed web machines, and particularly those which produce a transverse fold, must. be run at very high speeds, and they must be very strongly and substantially built in order to stand the strains set. up by the higlrspeeds at which they are run. This neces; "ztcsheavyframing and operating;- parts, requiring considerable space which was afforded by deflecting the webs. Ilcretofore, therefore, the advantages incident to a straight line or direct run of the webs have not; been obtained Where transverse fol ding mechanisms were employed.

This lliTYBIlt'lOIl has for its object to produce an improved folding mechanism for producing transverse folds in webs which are being run side byjside, the folding device for each web being 1 o hicatcd that the wells may be run direct. that is, in a straight line. without sidewise dctlcct'ion.

With this and other objects in view. the inrcntion consists in certain co'mtructions, and in certain hurts, in lr 'o'ements and combinations as will be lw-ivinaftcr toll described and then specil'a-ully pointed out.

Referring to the arcmnpanyin 'drawings----liignre 1 illustrates in diagrammatic side elevation a folding mechanism constructed in accordance with the invention. Fig. 2 is a front elevation ofthe construw tion illustrated in Fig. l.

c, cute two webs which arc adrailrcd side by sideunderneath a guide roll 3.

et. and?) indicate two similar webs which guide roll 6.

Machines constructed in'mrcorda-nce with the invention will em ploy transrerse folding mechanisms, that. is. folding mechanisms which are to produce 'tolds which are transverse to the run of the web. \Vhile the particular construction of transverse folding mechanism employed may be raricd, in the construction illnst'atcd, tl'iefolding mecha nisms are of the. rotary type and there will be one setof such rotary folding mechanisms for each of the webs which are advanced side by side. In the particular construction illns tratcd two such rotary folding IDQCl'ItIIilSIflS are employed, these folding mechanisms being superposed. One of these folding mechanisms, ae'illustrated, comprises a tucking cylinder 7 and a jaw cylinder 8, this form of trai'isverse folder being well-known in the art. The other folding mechanism illnst 'ated comprises a tucking cylinder 9 and a jaw cylinder 10, these cylinders being similar in character to those just described. Prior to being operated upon by the cylindcrs 7,8 and 9, it the webs should be separated into sheets. in the particular construction illustratml. this is eti'cct-cd by rotary cutting cylinders the cylinders operating in connection with the folding cylii'idcrs T. 3 being marked 11, IL- and 13, and the cylinders operating in connectionwith the fold ing cylinders 9, 10 being marked 1-1-, and 16. In this cutting construction,the cylinders 11, 1-3 and 14, t5 operate to partially sever ,the web; the webs being completely severed by the cylinders 13 us operating in Referrin to the drawin 's. l and Q 'in:ti-.

are advanced sideby ride underneath a the side frame 40. It will be observed that lead the webs l 'and 2 directly into the foldconnection with the cylinders 12, 15.

- sheets from the cylinder 10 are directed by .rclation to the side fra'n'les 35), 36 that the 'sc'ribed,it is possible to make the two sets of ,n'ndthe parts connected therewith, as strong This 1 double cutting construction enables forwarding tapes 17, 18 to be employed, by which the webs formed may be positively advanced to the folding cylinders. In the particular construction illustrated, the sheets finally cut by the cylinders 12, 13, 15, 16 are advanced through guides 19, 20 to the cylinders 7 and 9 respectively, tapes 21 and 22 being employed in connection with these cylinders to keep the sheets on the cylinders.

After the transverse folds have been effected in the webs l and 1, in the particular construction shown, the sheets may be delivered in any suitable manner. In the particular construction shown, the sheets from the transverse folding mechanism 7, 8 are directed by a guide 23 into a tape pathway consisting of two sets of coacting tapes 24, and to a rotary fly 25, which fly in turnde-. livers the sheets to a carrier 26 of ordlnary construction. If desired, tapes 27 may be used to cooperate with the cylinder 8 and the guide 23 in forwarding the sheets. The

means of a guide'28 to a pair of rolls 29 which in turn deliver the sheets to a fly 30, this fly depositing them on an ordinary carrier 31. Tapes, as 32, may be employed to cooperate with the cylinder -10 and the guides 28 in forwarding the sheets.

The folding mechanisms may be mounted and driven in any suitable manner. In niachines constructed in accordance with the invention, the transverse folding mechanisms whatever be their' construction Ewill be superposed and will be so located tha the webs may be led direct, that is, without sidewise dt fiection, to the mechanisms. In the machine illustrated, the folding cylinders 9, 10 are mounted on shafts 33, 34:,gthese shafts being supported in side frames 35, 36. The cylinders 7, 8 are, in the particular machine illustrated, mounted on shafts 37, 38, these shafts being-supported in side frames 39, 40. These side frames 89, I0 are, in the particular machine shown, carried on cross bars 41 which are supported in part on the side frames 35, 3G, and in part by a frame 42 which, as shown, may be a continuation of the side frames 39, a0 are so disposed with folding cylinders 7, S and the parts connected therewith are offset with respect to the folding cylinders 9, l0 and the parts connected tl'iere 'vith. By superposing the folding me'chanisms'andarranging them as defoldingmechanisms, their shafts and frames,

as may be necessary and at the same time to -1ng mechanisms, that is, without deflecting them sidew-ise.

When, as in the particular construction illustrated, two sets of webs are advanced in superposed paths, they are conveniently handled and directed to the folding mechanisms in the same manner as if a single set of webs were employed. In that case, the right hand halves of the webs marked 1 and 4- can be-led directly through the cutting cylinders into the folding mechanisms, the webs being associated, in the particular construction illustrated before they reach the cutting cylinders. In' the same way, the left hand webs 2, 5 are led direct to the cylinder 9, 10, the webs being associated beare advanced side by side underneath a these cylinders.

The driving mechanism for the folders may be of any suitable character. In the construction shown, the main shaft is illustrated at 40, this shaft carrying a miter gear 44 which meshes with a cylinder 45 on a countershaft 4:6. This shaft carries a driving gear e7 from which, through suitable gearing, the various devices which constitute the lower folding mechanism may be driven. The shaft 46 also carries another driving gear 48 which, in the machine shown, through a suitable vertically arranged train of gears, drives the upper folding mechanism. The construction illustrated further lends itself readily to the operation of either folding mechanism independently in case it be desired. By forming the gear 47 so that it may he slid on its shaft and connecting its hub to the shaft.

in any suitable manner, as by a set screw 49, the operations, of the lower folding mechanism are interrupted. Similarly, by arranging one of the train of gears which drives the upper folding mechanism, as-for instance, the gear marked 50, which is the gear which meshes directly with the gear &5, so as to slide on its support or stud 51, the operation of the upper folding mechanism may be interrupts It will be understood that suitable web guides not necessary to describe will be used where necessary in order to properly control the webs.

Changes and variations may be made in the construction by which the invention is carried into effect. The invention is not, therefore, to be limited to the specific constructions hereinbefore described and illustrated in the accompanying drawings.

What is claimed is 1. The combination with means for advancing a plurality of unfolded webs side by side, of a plurality f superposed folding mechanisms operating to produce foldstransversely to the run of the webs, and guides whereby said webs may be led direct to the folding mechanisms.

2. The'combination with means for ad vancing a plurality of unfolded .webs side Webs running side by side, of two superposed folding mechanisms operating to produce folds transversely to the run of the Webs, means for leading the right hand web of each set direct to one of the foldingmeehanisms, and means for leading the left hand web of each set direct to the other folding 15 mechanisms. I

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