Patent ed Nov. 14, 1911.

To all whom it may concern:

Be it known that I, EDWARD P. SHELDON, a citizen of the United States, residing at New York, county of Kings, and State of v New York, have invented certain new and I products.

In certain printed publications, such, for instance, as weekly papers or magazines, the. reading matter and much of the advertising matter can be produced on high speed rotary web printingmachines. It is, however, frequently desirable to include in the publication what may be ternied specially printed sheets which may differ from the web sheets either 'inthecharacter of the paper, or in the character of the printing, or

both. For instance, it is frequently found desirable to include in the publication a picture which may be equal in size to two pages of the publication, and it is also frequently desirable to include in the publica;

publications frequently, also, are provided with covers of such a character as to make it advisable -to produce them on machines difi'erent'from these which print the main body of the publication; Further, the pages forming the publication may be so numerous as to render it impractical to print the entire publication on a single web machine without unduly increasing the number or size, or both, of, the printing couples of the machines.

The present invention has for one of "its,

- objects to produce an improved mechanism for assembling printed products which is capacitated to produce a combined product by uniting with sheetssevered from a web or webs'what may be termed inset sheets and other sheets, such as cover sheets.

A-further object of the inventionis to produce an improved mechanism for printed products capacitated'to assemble a combined pr'oductby unitingwith sheets severed from a web or webs what may be termed inset shcetsj and other sheets, such as cover sheets, said meehanisln also including .de-

vices by which the various sheets or pages constituting the produc; may be secured together.

'A further object of th 3 invention is to 1'0- duce an improved mechi nism for assemb in printed products which shall be capacitate to unite with sheets cut from a web or webs other full width sheets w 'hich may be termed inset sheets, said product having its web sheets outside of the ins 5t sheets.

A further object of th invention is-to produce an improved mecha nism for assemblin printed productswhich shall be capacitated to unite with sheets cut from a web or Webs other full width sheets v *hich may be termed inset sheets, said pro luct having its web sheets outside of the ins 5t sheets, said mechanism also including me ans for securing the combined product together on a line central of the sheets.

A further object of t-hl i invention is to produce an improved mecha nism for assembling printedproducts which shall include a collecting cylinder, said cylinderbeing combined with mechanism For presenting to it two productsat difi'eren; points in the same revolution of the cylinde r, the products having their heads in r ing provided with'suita ole devices for taking these and a product presented on a. subsequent revolution, an for manipulating these devices to effect the taking the products at the proper time; and releasing the assembled product for d ilivery.

iVith these and other objects'not specifically referred to in view, the invention consists in certain construct ions, andin certain parts, improvements ax d combinations as will be hereinafter fully described and then specifically pointed out.

Machines embodying t] e invention W111 mof any suitable construction.

elude web forwarding devices which may be In the par- I ticular machineillustrated, these web forwarding devices include the bending rolls 1 and nipping rolls 2 usually emplo ed in fast rotary printing machines. Suite le devices will'also be employed for severing the web I devices into sheets.

' be varied, in the particular machine illusor webs passing thromgh the web forwar ding hile these means. may

trated, these devices comprise a pairof cutting cylinders 3, 4, the cut-ting cylinder 3 beingprovided with two'knives, as 5, and the cylinder 4, with two cutting woods, as 6.

Machines embod ing the invention, as to all its features, wil include means for forwarding what may be termed, for conyenience, inset sheets and where, as in,

I the machine selected to illustrate the invention, a productis to be produced which comrises not only web sheets and lnset sheets But also outer or cover sheets,- means will be employed, for forwarding such cover sheets.

The inset sheet feeding means and the cover feedin means, when both are employed are locate on opposite sides on the path of the webs or sheets cut therefrom.

The ,means for forwarding the' sheets -which have been referred to as inset sheets. may be varied in construction, but, in the best constructions, they will be of such a character asto forward a multi-length sheet and sever the sheet into the, proper sheet ,len hs. In the particular machine illustrate the inset sheets referred to are forwarded by devices which include feeding rolls 7 and a guide 8 of a usual type. While' the articular construction of cutting means empoyed may be varied, in the construction illustrated the cut-ting is effected by a reciprocating cutter 9 which may be operated in any-usual way, this cutter cooperating with a bed or block 10. A

Timing devices may be-employed which may be of such a character as to time the inset sheets not. only with res t tothe cuttin mechanism but also wit respect to the su'sequent devices which are to act in forwarding the sheets, in order that they maybe assembled with the web sheets before referred to. While the construction of these timing devices may lie varied, in the articular construction illustrated,'-they inc ude two drop rolls 11, 12, the roll 11 being car- 'edion an arm 13,-and the roll 12 on an arm 14, both these arms being carried on a rock shaft'15, so that they operate -simultaneously, and a sheet stop comprising fin- 6 gers 16 of the ordinary type, these fingers being mounted on a shaft 17. In the construction illustrated, the shaft 15 is operated from a forked connecting rod18 also'of the usual type, this rod'being connected to the arm 14 and being moved by a cam, indicated at 19, mounted on a shaft 20. The shaft 17 lengths, so that a plurality of sheets sheets will be forwarded .80 may be'varied, 'm the particular construction illustrated,

to say, y

is provided with an operating arm 21 which may be driven froma cam of ordinary construction, not shown. The drop rolls 11, 12 cooperate with driven rolls 22, 23, as usual in such constructions.

Where, as in the machine shown, the

mechanism for forwarding the inset sheets o crates in connection with a multiple length s eet, there will be employed, in machines which embody the invention in its best form,

nism as so far described, a multilength sheet is first forwarded by the rolls 7, and the drop rollers, until its leading end strikes the ends of the stop fingers 16. The knife then descends and cuts, after which the leading end of the leadin sheet formed by the cutter is carried aroun by the cylinder 24. The drop rollers 11, 12 then start off the second sheet,,the stop 16 being, in the meantime, dropped, the second sheet being timed so that its leading end meets the leading end of the first sheet as the cylinder 24 'completes'its revolution, the two sheets being then forwarded, in the particular construction shown, by two" rolls 27, 28 around which pass-ta es 29, these tadpes also being sup ported" y rollers 30 an by other r01 ers, as

is common with constructions of this class. In the construction shown, the sheets are directed intothe taped pathways referred to by a switch 31 mounted -on a shaft 32, this shaft being 0 ratedb an arm 33 and a cam 34 mounts on a sha particular -machine illustrated, the inset sheet, or, where a pluralityof sheets are for,

as 35. 'In the warded, the insetsheets, are assembled with "the web sheets in such a way that the inset,

sheets are inside of the 'web sheets, that is form the inside pages. of the product. A

The amembling mechanism, by which the web sheets and the inset sheets are united, may be varied in construction. In the best constructi ns and as shown, however, this assembli mechanism include a receiving cylin er, as 36, which may be a three v part collecting cylinder, this cylinder being mounted on a shaft, as 37. In the particu- '1 lat machineillust-rated, in order to unite the inset sheets withthe web sheets in the mana ner stated, that is to say, to form the inside sheets of the presented to the naked surfaces of the threeproduct,.the inset sheets are part milit a;

' best construction, these sheet taking devices will consist of grippers. In the particular machine shown, the cylinder is provided, as to each of its three sheet'rcceiving surfaces, with two sets of grippers 38, 39, one set of these grippers, as 38, operating to take the 1 inset sheets, and the other set of'grippers,

being common in web presses,

as 39, taking the web sheets.

The forwarding devices forthe web and web sheets will be so constructed as to properly present the web sheets to the assembling devices. In the particular machine shown, the web sheets are received from the cutters and presented to the receiving cylinder by guldes, as 40, these guides being hung on rods 41 and having cooperating therewith driven rolls 42, this construction 0 In the particular machine illustrated, the product consists of two inset sheets which form the inside pages of the publication, there being collected with each two inset sheets four successive cuts-from the webs.

In order that the inset sheets may form the inside pages of the product, they are, in the particular machine. shown, and as has been stated, first laid against the naked surface of the cylinder, the first collection of web "sheets bein presented to the cylinder later in but on t e same revolution of the cylinder on which the'inset sheets are presented. In the particular'machineshown, thegrippers 3-8 take the inset sheets and the grippers 39 take the web sheets.

The mechanism for operating the grippers may be varied in construction, but

.collection 0 where, as in themachine shown, the product is to include successive collections of web sheets withthe inset sheets, the collection occurring in the manner which has been described, the ippers should be operated in such a way t at the grippers for taking the inset sheets may, after the first collection of web sheets which isdepositedpntop of them, be withdrawn from beneath these web sheets and closed upon both the web-and inset; sheets, so that the web sheet taking grippers ma be opened to receive the next web sheets, thereby insuring the retention of the sheets in register, and

both sets of grippersshould be opened at the, proper time to permit thedischarge of the collected product. When, furthermore, as in the machine shown, the inset sheets are to be delivered to the naked surface of the in the same-revolution, itis of'course, necessary that the inset sheet taking grippers and the web taking grippe1 "s operate in succession. In the particular machine illust-rated, the sheets are delivered from the rolls 30 and .the taped naked surface of the cylin ler, the heads of the sheets being taken by' the grippers 38. These grippers (see Fig. 2) are mounted on a rock-shaft 43 which ha sextendin from it an operating arm 44 p 'ovided withthe usual'roll, this roll being arranged to contact with acam 45. The s iaft 43 is mounted in arms 47 extending from a shaft 48, this shaft having an arm :9 provided with the usual roll arranged tn contact with a cam 50, the cams 45 and 50 bein carried on the frame of the machii e, It will be understood, of C0-11IfSe,"tl\ - 1tr tne shafts 43 and 48 are provided with the u ,ual springs com-- mon in ripper construction and omitted from the illustration in the interest of .clearness.

WVith the construction [8 described, the roll on the arm 49 first st rikes the cam 50,

pathway 29 to the this rocking .the shaft 48 and drawing the grippers back.. While the roll on the arm 49 is running up on the ca :11 50, the roll on the arm 4-4 is in contactlw th the surface of the cam 45. The first pa .1; (if this cam is practically concentric, thoi gh it may be and preferably willbe so forned asvto exercise a slight lifting action on t] e grippers. Just 1 sure roll, as 51, may be em rloyed to hold the heads of the sheets down against the surface of the sheet taking :ylinder so as to insure their being taken by the grippers. \Vhen such a roll is empoyed, it may, in

order to set it close to the s best taking point,

have its surface cut-away to form segments 52, these segments atlo'rd'ng room forthe movement of the gripper fingers.

When the heads of the sheets have come Within the range of the gr: ppers 38, the rolls on'the operating arms for hese grippers run off the cams 50 and 45, t; 1e grippers being closed on the sheets by t 1e springs before referred-to and not illusti ated. The cylinder continues its moveme it with the inset sheets in the grasp of the grippers until it reaches the point where t 1e web sheets are tobe presented to it, these web sheets'being, t

on a rock-shaft 53, this sh ifthaving an op-, crating arm Mprovided v ith the usual roll.

in the construction illustr: ted, taken by the grippers 39. These grippers are mounted The operating means for the shaft 53 in clude a swinging can1'55 pivoted at 56 to'the' frame of the machine, this cam being operated by a connecting rod 57 forked at its upper end to'embrace the shaft 35,.the end of the rod being provided with-a cam roll and being operated by a closed cam on the shaft 35, as is, common in such constructions, the illustrat ion being omitted in; the interest of clearness. These eonnectionsoperate the swinging cam 55 so as to open the grippers just prior to the time the inset sheets are delivered, thus avoiding disturbing. the heads of these sheets by the grippers. At the time the cylinder reaches the pointat which the .web sheets are delivered, therefore, these grippers are opened, and as these sheets are delivered with their heads in register with the inset sheets, the operating roll on the'arm 54 runs off the cam and the grippers snap .into closed position, the closing being effected by the usual spring construction. r

-The cylinder, having taken the-web sheets,

continues its revolution, the product on the cylinder at thistimebeing the inset sheets held by the grippers 38 and the web sheets held by the grippers 39, these sheets being superposed upon the grippers 38. When, as in the machine shown, successive collections of web sheets are to be made, it is desirable,

as has been indicated, that :the grippers which are holding the inset sheets, bewithdrawn from beneath the web sheets and clamped upon the ed es ofboth the web and inset sheets, so that the register of the sheets may be preserved during the time the web sheet grippers are taking the additional, sheets necessary for the collection. To effect this, in .the construction shown, cams, as

58,- 59, are provided which are arranged to withdrawn from beneath the sheets by the action of the cams 58, 59, they close upon the sheets and the cylinder continues its revolution. As. the grippers 38 pass the taking point for the inset sheets they open and close idly, no inset sheets being pre sented to them, in the particular machine illustrated, at this point in the revolution of the cylinder. At the time the grippers38 are passing the taking point for the inset sheets, the cam 55 for operating the grippers 39 is dropped and remains dropped until the grippers 38'have closed, after which this cam is actuated to open the grippers 89 so that when they,arri"e at the taking point for the web sheets they are-ready to and do close upon these sheets. When the desired number of cuts from the web The cams 58, 59 are located at suchv apoint in therevolution of the cylinder,- that the delivery "of the sheets will take place after these cams have opened the grippers 38. In order to effect the openin of, the

grippers 39 to enable the sheets to delivered, thereis provided a cam 60 mounted on an arm 61 extending from a shaft .62 rocked from an arm 63 and a cam 64 mounted on a shaft 65 -This movement of the shaft 62' interposes the cam 60 in the. ath of the roll on the arm 54 and thus roc the shaft 53 so that both sets of grip ers are simultaneously opened to enable tie sheets to be de-,

livered. The cam 64 will, of course, be designed to throw the cam 60 into operative position only after the desired number of collections have been made.

. The delivery of=the sheets may be effected in' anysuitable manner. In the particular construction illustrated, the sheets are delivered bv a delivery cylinder. 67 mounted on a shaft 68, this cylinder being provided with a set of grippers 69. These grippers are mounted on. a shaft 70 provided with an operating arm 71, this arm being operated upon by cams 7 2,7 3. The cam 73 is mount-- e on an arm 74 in turn mounted on a stud 75. The arm 74 is connected by a rock arm 76 and a stud 77 with theshaft 62, so as to throw the cam 72 into operative position simultaneously with the operation of the cam '60, thus opening the grippers 69, these grippers being closed by the ordinary spring eonstru'ction, not shown. In the particular 'machine shown, the grippers, 69 deliver the sheets to conveying ta es 78, \79, the cam 73 opening the'grippers or this purpose.

In the articular machine shown, it may be desired to produce a product comprising not only the inset sheets and the web sheets before referred to, but also a cover sheet or sheets which will, of course, be applied to the outside of the web sheets, and the particular machine illustrated is provided with means for effecting this. The cover web is indicated at C, the covers being intermittently fed in by rolls 80, 81, the roll 81 having 'a segmental operating surface 82 to effeet the intermittent feeding of the covers.

In the particular machine illustrated, a guide, as 83, operates in connection with the cover feeding rolls to deliver the cover simultaneously with the web. sheets, as the same are taken by the grippers on the sheet receiving cylinder 36. The rolls 80, 81 will, of course, be so timed as to present a cover simultaneously with the last collection of web sheets. Y

' In the best constructions embodying the invention, securing means will be provided for uniting the s eets. on the central fold line. This may be accomplished simply by i 1 revolution of the cylinder.

folding, but, in the best constructions, it will be accomplished not only by folding, but also, by some permanent secur ng means, such as stapling. In the particular construction illustrated, the shaft 65 carries a stapling roll 84, this roll being provided with stapling mechanism of the usual type, indicated at 85,, actuated in .theusual manner to insert the proper number of staples alon the fold line of the product. In the particular machine shown, after the product has been stapled and delivered, it is presented by the tapes 78, 7 9 to a striking folding blade 86, operated in the usual manner, which folds the product along the foldline.

It has been heretofore stated that the roll 24 which operates to superpose the inset sheets-is provided with a set of grippers for this purpose. These. grippers, of course, op crate, when superposlng the sheets, in the manner described, only ,upon each second To effect this,

- the'shaft which carries the roll 24 may be scription.

provided with a movable cam 87, this cam being operated from a forked rod 88 inturn operated, in the usual manner, from a cam, not shown, on the shaft Should it be desired not to superpose sheets, this cam may be locked in any usual way, so as toretain the grippers open, thus permitting the sheets to pass without su erposing.

The operation 0 the mechanism will be fully understood from the foregoing de- Changes and variations may be made in theconstructionby which the invention is It is not,,therefore, to

be confined to the particular construction means for assemblin herein shown and described.
