To all who/u 'z't'may concern Be itknown that I, [laws 0. Scimonosu, a subject of the German Emperor, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful lmprm'ementsin Sheet-Assembling B'Iechanism for Printing-lresses, of which ,niechanlsm for printing presses and. its obthe following .is a specification, reference being had to the accompanying drawings.

This invention relates to sheet assembling ject to provide a new and improved form and arrangement of such sheet assembling mechanism. p

One of the objects of my invention in particular is a new and improved arrangement of such mechanism by which the separate sheet feeding devices areplaced within the main frame of the press instead of outside of the-same, and whereby not'only is floor space saved but a more convenient and accessible'form of such delivery mechanism is provided. i

" Other objects of my invention are to pro-' vide a new and improved form of sheet assembling mechanism in which a number of webs are gathered together and cut into sheets forming the main body of the paper,

in which insert sheets, after being fed to a suitable table, are folded centrally and thus folded are brought into association with the lnain'sheets in position to be uponthe' inside of the folded product and in which cover sheets may be associated with the main sheets and insert sheets in such position as to be on-the outside of the folded product.

Referring to the drawings,-Figure' 1 is a front elevation diagrammatically illustrating my invention; F1 2 is a side elevation;

and Fig. 3 1S an en arged detail, bein aside elevation of the sheet folding and or- I warding mechanism of theco-ver sheets.

' web. Of course, the. number may be. in-..

I )whether they come from six separate webs creased or diminished and it is immaterial or from one O1'-lll0l'Q webs slit into sections in any \vell-k'nown way. Passing over the guide-rollers thewebs pass over angle-bars 12 of the well-known form and description by which they are deflected and passing over "suitable guide rollers as 13 are brought together in registry and associated between registering rolls 14 in the well-known manner. Passing the registeringrolls 1a in registry the webs pass between cutting cylinders '1.51( where they are severed transversely in the well-known manner and are led between suitable guide-rollers as 1.7 to acollecting cylinder 18. The sheets severed from the superposed webs are collected upon the collecting cylinder 18 in any well-known and approved I'nanncr forun'ng of itself no part of my invention. 'lvheii a sutliclent number are collected the lead edge is released from the grippers 19, with which the collecting cylinder is provided, after the 'lead edge has passed roller 20 and the sheets pass between guide-blocks 21-22 downward and forward adjacent to gripper cylinder 23 to be associated with the insert sheets as hereinafter described. 1

Referring to Fig. 2, where it is best shown, 24 indicates a suitable sheet forwarding mechanism, preferablysuch as that of the .well-known Cross type, which is adapted to forward the insert sheets 25, which have been previously printed, in the well-known 'manner. The sheet forwarding mechanism 24 is, as is shown in Fig. 2, located within the main frame 4 and directly behind a' folding and forwarding mechanism hereinafter described. One of these forwarding mechanisms is laced lipon each side ofthe machine behind the folding devices hereinafter described, although only one is shown in Fig. 2 of the drawings to avoid unduly complicating the drawin 's'. The sheets are delivered by the sheet forwardingmechanism 24,,one at a time, and in a direction parallel with the run of the main webs 6 to 11, inclusive, 'nto tape paths 26-27 by which the sheets are fed one at a time forwardupon a. foldin table28 against a stop.

29 between. guidin ledges 30 (see Fig. 1).

Actuated at suitab 0. known mechanism a folding blade 31 0 erates to tuck the central margin of the s eet fed upon table 28 between folding rollers 32 ,into tape paths 33-34 by which the intervals by i any well-- y a table against the stop 1' the main webs and described, at

sheets centrallyfolded are fed down upon 36, which is adapted to -,be raised at suitableintervals by any well-known mechanism. At suit-.

able intervals the gripper cylinder 23 engages the lead edge of the folded sheet and carries the same around cylinder 23 so as to bring the lead edge intov register with the lead edge of the pile of sheets severed from collected upon collecting cylinder 18 in the mannerabove described. 36 indicates a second table like the table 28 to which sheets are fed, by a suitable feeder like that above directly behind the table and within the framework of the ress.

37 indicates a folding tucking lade, which,'opera'ted by mechanism, hereinafter suitable intervals folds the sh'eetcen'trally tween .folding rollers 38. paths 39-40 the folded table 41 and brought against a stop 42,

By means of tape which will behereinafter more fully described.

43 indicates rollersabove the table 41. 44 indicates a pressure roller adapted to co-act with roller 43 at suitable intervals andwhich is raised so as to co-act with roller 43 at suitable intervals in the manner hereinafter described, Whenever the rollers 43'-44 are brought into. operative 'relation and the stop. 42 is removed at suitable .in ter valsthe sheets are fed into tape paths 45 -46 and the parts are so timed that the lead edge of this. cover sheet will be brought intoregistry'with. the lead edges of the main sheets and the insert sheets, brought together as. above described, and below the main sheets. By means of these tape paths the associated insert sheets, main sheets and cover sheet are brought together upon a 1 table 47 against aregistering stop 48 from which they are folded by the usual folding blade as 49 operated in the well-known manner between folding rollers 50 to any suitable delivery mechanism as delivery 0 linder 51 and tape paths 52w The cover s eets' may be of only one-half width transversely of their run in which:ease,'of course, they v will not be folded. -In this case they are ed into the bite of the rollers fed upon the left blade 37 in this "case acts to push the side ed e of the sheet between rollers 38, the sheet ein forward 38 a movable pressure, roller .53 (see Fig. 3 herein- 4 li ter described.

f 'Refe'rring'to Fig. 3, 53 indicatesaroller which is mounted upon arms 54 on a rockshaft55 and is adapted, whenthe'shaftis rocked as hereinafter described, to press. upon the surface ofthe sheet when only a single width sheet is used for the cover as last above described {56 indicates" an "arm' a suitable cam as described, and located, 1 as has been described above,

in the direction of its runbesheet is led to a be p I hand side '(see'Fig. 1) of? the'table' 36.- ,The folding What I claimas my invention,

on rock-shaft 55 which, means of an arm J 57, is operated by a cam 58 on shaft 59; The

cam 58 is so shaped as to move the arm 57 to .rock the shaft 155 at suitable intervals to bring the roller saints contact with the paper and coiiperate with the-folding blade 37 as above described. Referring' to the same drawing, the folding blade 371smounted upon an 'arm 78 on rock shaft 79, which is rocked by arm 60 and link (il-operatedby cam is-so. arranged that the knife will 0 )cr-I ate at suitable intervals to forward the s eet whether folded or not, folded to stop 42. The stop 42 is mounted upon anarm 63 on a rock-shaft 64 journaled in. any suitable way in a frame and provided with rock-arm '65 which is operated by arm 66 and cam 67 on the shaft 59." As is'best shown in Fig. 3, the stop 42 is provided with a guide 68 which extends outward from the stop and I nds downward and inward toward it so as to prevent the lead edge of the sheet from being carried upward in anyway. The cam. 67 is so arranged as to operate at suitable intervals to ermit the sheet to be forwarded in time for 1ts lead edge to come into regis-' try with the main sheets and insert sheets as above described. Theforwarding of the sheets at suitable intervals when the stop is raised is effected, as above-stated, by rollers 43 and 44, of which the roller 43 is fixed and the roller 44 movable. As is best shown in Fig. 3, the shaft of the roller 44 is spring seated upon arnrfit) on a roclsshaft 71. The rock-shaft 71 is. operated by another arm 72 and link 73 and cam74 onthe shaft- 59. The cam 74 is so shaped and timed as to rock the shaft 71 and.bring rollers 44 into operative relation with; rollers 43 at such intervals as to forward the cover sheet into the tape, aths 45-46 and meet the main sheets an insert sheets with their lead edges substantially together. That is to say, when all the/sheets, the insert sheets, the collected main sheets and" the cover sheet are brought together at the lower side of delivery cylin der 23-into the bite of the tape paths 45 and 46 they are substantially in register and as I so'ciated together. "The registry is completed and the sheets brought into proper association for their final fold by being brought against the stop 48 as above described.
