Be it known thatI, YVALTER SCOT C P, a citizen "of the United States, and a resident of Plain field, in the county of Union'and State of'New Jersey, have invented-certain new and useful Improvements in Delivery Mechanism, -.of which the following isa'specificatioir' Thisinvention relatesto improvements in the folding and delivery apparatus of that class of machinery known as web-printing, folding,'and delivering" machines, and has for its object the simplification of such machines, so that a great variety of products can be produced and delivered thereby and the change from one prod uct to another be quickly and easily made with but few adjustments of parts.

Theinvention consists of combinations of devices, as hereinafter more particularly described, and pointed out in the claims coneluding this specification.

The preferred form of the invention is shown in the accompanying drawings, form-- iug part of this specification, in which-- Figure l is a diagrammatic side elevation showing the cylinders of printing-presses and two folding and cutting machines; and Fig. 2

indicate four rotary web-perfecting printingble-width web two single-width webs edge to edge may be employed. .Whendouble-width webs are employed, the slitters commonly used for slitting-webs longitudinally are tobe employed, as will be understood. The four folding, cutting, and delivering mechanisms G G G G are shown as being arranged in pairs, and the pairs are shown as being ar- 1896- Seriflho-GOGjBOS. utomoaerr l 1 ranged vertically one over the other orin different horizontal planes. The webs a b are led over'the rollers'rifwhere they areassociate'd, andihenceareledovera rollertphelongitudik nal half to the mechanism G and the other lonf '2 "6o gitu dinal half to the mechanism G2. The webs c d are associated at the roller r4 audthence are led overa rollert to the mechanisms G G4," or the webs 0 cl, or one of them, maybe associated with the webs ab, and associated webs all be led over roller t to the mechanisms G G, and other combinations, as will be here inaft'er described, may be made with these,

Webs or parts thereof to form' various'products. The mechanisms G! G? G G maybe duplilivery of the products in oppo'sitedirections the drawings as difiering in details and accomplishing the same end'in substantially identical np to a certain point, as will now the same way} The mechanisms G G are,

be described, each consisting of alOn gitudinalfolding mechanism composed'of theinternal former .or guideV, theexternal guides 2, the cutting or perforating cylinders 3 4, the

.guidesb, and tapes 6, by which the webs-0r sheets are guided 10. the grippers 15 on the carrying-cylinder F F The folding-rollers 8 coact with the folding-blades 16, which are protruded through longitudinal slots or openings in the cylinders F F toforce the'sheets" between said rollers. The tapes brunupon rollers or -bhlleys 7 a'nd one of thesaid folding-rollers 8, Guides 17 and pressure-rollers p coactwith the'cylinders E E to retain and feed the sheets, as will hereinafter: be ,de-

scribed. As thus far described theinechair. isms GandG areduplicatesofeachothenand, as stated above, they may remain so'tothe" end; but I have shownlhem from this point onWard in the drawings as differing intheir 7' cates each of the other, except as tothe ar rangem'ent of the parts, so'as'to make the deers 8 are taken by the tapes 6 6 (the latter set of tapes running upon the lower of the folding-rollers 8 and a set of pulleys 7) and delivered downwardlyin front of fixed guides 18, from which they are pushed upon the traveling tapes 12 of the receiver by means of the rotating arms S in a well-known manner.

The cylinders F F are each provided with three sets of grippers 15 and with two foldingblades 16.

This mechanism isfully described and claimed in my pending application filed on the 29th day of August, 1895, Serial No. 560,881,now Letters Patent No. 572,280,dated December 1, 1896, and need not be described herein further than to say that the times of revolution of the cylinders I F and the folding-blades 1 6 are as two to three-thatis to say, each set of grippers 15 will pass the folding-rollers 8 twice, while each folding-blade 16 will pass the same point three times, all as fully set forth in my patent aforesaid.

The grippers 15 are operated by suitable mechanism (not shown) as follows: Each set of grippers may be caused to take the leading edge of a cut at the point where the gnides'5 and tapes .6 present the same to the cylinder at every time the said grippers pass that point. (See cam 100.) If the cuts are to be folded separately, as in producing four to eight page products from a single web or associated webs, these sets of grippers are operated at the proper time to open them to allow of the folding-off by the blades 16 and rollers 8 of the said cuts. If, however, cut-s from the web or associated webs are to be collected by the cylinders F F in the manner described in my patent aforesaid, then one of the blades 16 is rendered inoperative or inactive, and the mechanism for opening the grippers 15, so that the sheets may be folded off the said cylinders, is adjusted so as to open said sets at such times only during alternate revolutions of the cylinders F F all as in my aforesaid patent is fully described. ThegripperslOofthecylinderllare operated at proper times by suitable mechanism to cause them to take and to release the folded products delivered to them from the folding-rollers 8. References 9 indicate gearing similar to that shown in said patent for operating the blades 16.

By' the aforesaid arrangements of parts and a single web products of four pages or with collection by the cylinders F F prodnets of eight pages, may be delivered from the mechanisms G G With two associated webs two eight-page products may be delivered by the said mechanisms and two sixteen-page products may also be delivered by collecting cuts, as above described, from each longitudinal half of the associated webs. By arranging mechanism for operating the grippers 15 of the cylinders F F so that at the point where the cylinders are adjacent each other the grippers of one cylinder will release the cuts held by it and the grippers of the other cylinder will take the cuts from the opposite cylinder a transfer of the cuts from one cylinder to the otheris made, and in this way a single thirty-two-page product may be .delivered.

Thus the grippers 15 of the cylinder F may be opened by a movable cam 102 as they pass the cylinder F, and the grippers 15 of the cylinder F, which have been opened by a movable ram 101, after passing the pressure-roller h are closed to take the cuts from the cylinder F and associate them with the cuts upon the cylinder F. The arrangement of the mechanisms necessary to do this in the case of a thirty-twopage product is as follows: The gripper-operating mechanism of the cylinder F may be arranged so that each set of grippers will be open to take a cut from the guides 5 and tapes 6 at the point where these present the cuts to the cylinder; also, the mechanism fol-opening the grippers when folding off is arranged, as above described, to operate these grippers only at each alternate revolution thereof, and in addition the mechanism for operating these grippers 15 to take cuts from the cylinder F is arranged to operate them, as above described, during alternate revolutions of the said grippers; also, one of the blades 16 on the cylinder F is renderedinoperative, as above described. The mechanism for operating the grippers 15 of the cylinder F is arranged to cause them to take cuts from the guides 5 and tapes 6, as above described, and to cause each set to open during alternate revolutions thereof as they pass the cylinder F, so as to deliver the collected sheets or cuts to the grippers thereof. The blades 16 of cylinder F are both rendered inoperative. The operation of the parts after these adjustments and arrangements are made is as follows: Each longitudinal half of the associated webs a b is separately folded, cut into sheets, and delivered to the grippers 15 of cylinders F F It may be assumed that the grippers 15 of cylinder F take and carry around the sheets, and theactive fold- IIO ing-blade 16 thereof folds ofi the sheets, as

illustrated in Figs. 8 to 17 of Patent No. 572,280, above named, except that the said sets of grippers 15 are opened as they approach the cylinder F and close to take the sheets from that cylinder, as will next be described. The sets of grippers 15 of the cylinder F are each opened to take sheets from guides 5 and tapes 6 and carry the sheets around and collect them, as shown in Figs. 8 to 17 of Patent No. 572,280, aforesaid, except that the collected sheets are not folded off between the rollers 8, but are carried on around to the cylinder F. Each set of grippers 15 of cylinder F opens only on alternate revolutions as it approaches or passes the cylinder F, and the set of grippers 15 of the cylinder F, which passes cylinder F at the same time, is operated to take the collected sheets from the cylinder F and the set of grippers 15 of the cylinder F, which is sqoperated, isa set 'by the cylinder ll upon the tapes 12.

or webs going to the mechanisms G G may be.

delivered single-that is, withoutcollctingby the cylinder F to the cylinder F and'eightpage or sixteen-page products be delivered arrangement of the mechanism necessary to do this is'as follows: Thegrippers 15 on each of the cylinders F F are operated to take cuts from the guides 5 and tapes 6, as above described. The folding-blades 16 of the cyl inder F are rendered inoperative, and both blades 16 of the cylinder F are rendered operative. The grippers-15 of the cylinder F are arranged to open as they pass the cylinder'F to release sheets, and the grippers 15 of the cylinder F are operated to take the sheets or cuts from the cylinder 15 at this point' and are also arranged to be opened'to release the collected sheets in order that the same may be folded off the cylinder F bythe blades 16 and the rollers 8. The cams 101 102 are stationary while this operation proceeds. Inasmuch as means for holding such camsfast are well-known, I have not shown the same herein.

Itis obvious that by suitable choice of width or webs, as single-width, half-width, one-andone-half-Width, and double-width webs, upon the presses A B by combining the products in various ways, sometimes collecting and sometimes not andsometimes transferring from cylinder F and sometimes not,I may obtain products containing six, ten, twelve, fourteen, twenty, twenty-four, and twenty-eight pages, as well as the four, eight, sixteen, and thirtytwo page products above described.

What has been said hereinbefore concerning the number of pages in the products obtained is based upon the assumption that each cut from each single-width web in the mechanisms G G contains but four pages. With the forms upon the cylinders of such size that each cut contains eight pages (or other multiple of four) then of course the number of pages in the products above described is increased in the same ratio.

The mechanisms G G differ structurally from mechanisms G G in that for the cylinders F F are substituted the cylinders F F each having two sets of grippers 15 and being provided with two folding-blades, which are operated in any suitable or usual waysuch, for instance, as shown in Letters Patent of the United States No. 215,844, granted May 27, 1879and that for the delivery mechanisms forming part of the mechanisms G G is substituted a delivery composed ofthe tapes 6, running upon the rollers 7.and one of the folding-rollers 8, and the tapes 6", running It results upon the rollers 7 7 and the lower foldingrollers 8, which tapes run the folded product out between the rollers 7 '7 and down between The guides k are placed so as to engage-the products only at' their edges, and the products are pushed the tapes 6 and the guides 76.

out by the vibratory arms m upon the'traveL ing tapes 12. The rollers or pulleys 7 and 7 are shown as being carried by pivoted arms for the usual purpose of tightening the respective sets of tapes running upon them. If it is desired to associate the web or the cuts from the mechanism G with the products formed by the mechanism G it may be done by rendering the folding-blades and the grippers 15* of the cylinder F inoperative and leading the transversely-perforated web around the cylinder 15', the cylinder 19, over the guides 20 onto the cylinder F and asso-' ciating them with the cuts. coming from the cylinder F The cams 104:, which may be removable, open the grippers 15 at the proper times. A set of tapes 21, running upon the rollers'or pulleys 22, coact with the cylinder 19 and guides 20 to feed the sheets forward.

The cuts of the web coming from themechanism Gr would beseparated from the web at the moment the folding-rollers 8 take the sheets, it being understood that in. all cases the tapes 6 and rollers 8 may acceleratethe speed of the sheets, and thus severthem from their webs in the well-known manner, or in case the cutters upon the'cylinders 3 completely sever the web the grippers 15 of the cylinders F may be operated "to take the cuts from the guides 5 and tapes 6 and to deliver them to grippers 23 upon the cylinder 19, which in turn open to deliver cuts upon the guides 20. Cams for opening the grippers 23 at the proper times are shown, but are not marked in Fig. 2. Such cams may be removable or otherwise arranged so as not to operate the grippers 23 when the cylinder 19 is not in use as a transfer-cylinder, whereby noise may be avoided. By the described arrangement of parts it is possible to deliver (without collecting) products containing two, four, six, eight, ten, twelve, fourteen, or sixteen pages from the machines 0 and D and by collecting products containing a greater number of pages may be obtained. In order to produce two-page products, a single-width web may be perfected in one press, the plates and the web being so placed that the split web goes half to mechanism G and the other half to mechanism G that is to say, the triangles V of these mechanisms merely act as turning-bars and not as internal guides of a folding mechanism, and the unfolded halves of the web are cut into sheets,'which are de-' I livered at opposite sides of the machine upon the tapes 12.

gle-width Web to produce the two-page copies.

In Fig. 2 several parts connected with the cylinders F 'F are omitted for the sake of clearness in the drawings. Moreover, such guides 25. Instead of adjustingthe whole of omitted parts are or may be of usual or known construction and operation. In the particular embodiment of the invention shown in the drawings it is arranged to take the webs from one or both the mechanisms G3 G o1' the cuts derived therefrom to either of the mechanisms F F and there associate them with the webs or cuts normally manipulated thereby. Assuming that the cuts furnished by the mechanism G3 G are to be associated with the cuts furnished by the mechanism G the arrangement of the parts shown is as follows: The folding-blades of the cylinders F F are rendered inoperative,and the grippers thereof are operated to take the cuts, as hereinbefore described, and to open in time, so as to deliver the cuts to the guides 25, which strip them from the cylinders, and to the sets of tapes 26. These guides and tapes direct the cuts downwardly between the rollers q, and the sets of tapes carry the cuts downward to the rollers or pulleys p, at which point the guide 27 and one of the said sets of tapes 26 direct the cuts to and upon the cylinder F where they are associated with the cuts coming from the web or webs manipulated by the mechanism G and are folded and delivered therewith. The sets of guides 25 may be adjustable cireumferentially of the shaft 28, by which they are carried and supported, so as to be adjustable into and out of circumferential grooves in the cylinders F F". Guides 24 serve to hold the sheets against the cylinders F F. The sets of tapes 26 run upon rollers 0, p, and q, as will be understood from the drawings. The guides 27 are adjustable circumferentially of the shaft 29 in order that the cuts delivered by the sets of tapes 26 may be directed upon either of the cylinders F F Instead of having the guides 25 adjustable upon their shaft in order to guide them into or out of the circumferential grooves of the cylinders F or F these guides may be fixed or stationary with respect to the said shaft and may have their ends jointed to them in the manner in which the blade of a knife is jointed to the handle, so as to open or close and be held in such positionby a spring, all as illustrated in Fig. 4, wherein ends 25 are hinged to the guides 25 and are held in different positions by means of the Hat spring 25".

In Fig. 3 the guides 25 are shown in the positions they occupy when the cuts are being directed along tapes 26 to and associated with cuts on either or both of the cylinders F F When not so associating the cuts, the guides 25 are loosened from shaft 28 and their working ends are dropped down out of the grooves in cylinders F F", so as to allow the cylinders to carry the sheets on around, and the guides are there locked to shaft 28 again. In the first-named case the sheet-retainers are caused to loose the sheets as these are diverted from the cylinders by the guides 25, while in the second case the retainers are made to hold onto the sheets as they pass the the guides 25 for the purposes described their working ends may be jointed to them, as in Fig. 5, in which the full' lines indicate the same positions of the endsof the guides asis shown in Fig. 3, while the dotted lines indicate the positions of the ends when sheets are diverted from the cylinders F F by the guides. The ends 25 are simply dropped down (dotted lines) instead of the whole guide 25.

The reference gin various figures of the drawings indicates gearing by which the parts are driven.

All four webs a b c d may be associated and led to one pair of mechanisms, as G G Thus the webs ab are associated at the roller r and the web (1 is led downward over the roller 1- and is associated with the web 0 at the roller 1' and the two webs are then associated with the webs a b at the roller 7- as indicated in Fig. 1 by the-dotted lines, and then all four webs are led over the roller zfto the mechanisms G G or to the mechanisms Gr G The last-named arrangement permits of the formation of copies containing two, four, six, eight, ten, twelve, fourteen, sixteen, twenty, twenty four, twenty eight, thirty-two, forty, forty-eight, fifty-six, and sixty-four pages, according to the number of half width, single width, one anda halfwidth, or double-width webs employed, the number of printing-presses run, and the use or non-use of the collecting mechanism and the transverse transference of the cuts or webs.

WVhat I claim is- 1. The combination with a plurality of double-width presses arranged one above another, of four longitudinally folding and transversely-cutting mechanisms arranged by pairs on different levels or planes and in the same vertical zone, a delivery for each of said mechanisms,and means whereby the cuts from the upper cutting mechanisms may be associated and delivered with the cuts from either or both of the lower folders, substantially as described.

2. The combination with a plurality of double-width presses arranged one above another, of four longitudinally folding and transversely cutting and folding mechanisms arranged by pairs on diiferent levels and in the same vertical zone, a delivery for each of said mechanisms, and means whereby the cuts from the upper cutting mechanisms may be associated folded transversely and delivered with the cuts from either or both the lower folders, substantially as described.
