MACHINE FOR ASSEMBLING PRINTED PRODUCTS.

Application filed March 12, 1910.

Specification of Letters Patent.

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 New York, have invented certain new and useful Improvements in Machines for As sembling Printed Products, fully described and represented in the followin specification and the accompanying drawings, forming a part of the same.

This invention relates to machines for as sembling printed products.

In an application filed of even date herewith, said application being serially numbered 548,786 there is disclosed a machine for assembling printed products consisting of sheets obtained from a web or webs printed on a high speed web press and other sheets difi'ering from the web sheets either in the character of the paper, or in the character of the printing, or both, and termed, for convenience, inset sheets. The specific machine disclosed in said above application produces a product in which the lnset sheets always form the inside sheets of the product. In the machine disclosed in said application, furthermore, the inset sheets are formed from a multilength sheet which is presented to a cutting device of such a character that the sheets are required to be sto ped during the cutting operation.

t is one of the objects of this invention to produce an improved mechanism for assembling printed products comprisin web sheets and inset sheets, the mechanism eing of such a character that the inset sheets may be placed either inside the web sheets or be tween the web sheets or both inside and between the web sheets.

A further object of the invention is to provide an improved mechanism for producin a combined product consisting of web s eets and inset sheets. formed from a multilength sheet, the devices for forwarding the multilength sheets including a cutting mechanism of such a character that the sheets maybe cut on the run.

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 hereinafter fully described and then specifically pointed out.

Referring to the accompanying drawings-Figure 1 illustrates inside elevation in sheet feeding mechar ism. In the ticular machine illustratad, two such which may be those usually employed to forward a plurality of webs printed on a high speed 1printing mac line. In the particular mac ine illustrated, these web forwarding devices are indi ated b the ordinary bending rolls 1 and nipplng rolls 2 commonly used in high speed printing machines. The web or webs forwarded by'the forwarding devices may be severed into sheets in any approved way. In the particular construction shov n, this is eifected by a pair of cutting rolls 2 of the usual type, one of these rolls being p1 ovided with knives 4 and the other with cutti 1g blocks or woods 5, as is usual in such constructions.

Machines embodying he invention will include sheet feedin me: ns for forwarding sheets which have been before referred to and termed for convenience inset. sheets.

I These means may differ 'v 'idely in their construction and character. Referring more particularly to Fig. 1, SE id inset sheets are fed to the mechanism by feeding rolls 6, 7 which forward the sheeti into the range of a drop roll 8 with which uotiperates a driven roll 9, the construction bl ing a common one arrop rolls are employed, the s acond drop roll 10 j cooperating with a dri ren roll 11. The means for operating these rolls is indicated,

but as it is common in the art, a description thereof is unnecessary.

In the particular mac ine illustrated, the inset sheets are .formed from multilength sheets, and in machines in which such sheets 'are fed, mechanism shou id be provided for severing the sheets into 5 ieet lengths. This mechanism, in machines embodying the invention in its best form will be of such a character that the sheets may be cut on the run. While the mechan sin employed may be varied in its characte: in the particular machine illustrated, the severing of the multilength sheets is etfe :ted by cutting cylinders 12, 13, the cylinder 12 carrying the usual knife 14 and the o3 linder 13 the usual coo crating block or wo d 15.

achines embodying the invention will usually include timing devices so that the inset sheets referred to may be presented at the right time to be properly assembled with the sheets cut from the web or webs, thus enabling an assembled product to be produced the sheets of which are in register. While these timing devices may be variously located, in the particular machine illustrated, they operate upon the inset sheets prior to the time said sheets are cut. The construc tion of these timing devices may, of course,

' be varied. As shown, they include a piv oted sheet stop 16 of a usual type mounted on a rock-shaft 17 this stop coiiperating with the drop rolls before referred to to time the sheets. v

Where, as in the particular machine illustrated, the inset sheets are formed from a multilength sheet, and it is desired that the mechanism simultaneously present a number'of inset sheets for assembling with the web sheets, means should be provided for superposing the sheet lengths cut from the multilen h sheet. Mechanism for thus superposing sheets formed from'the multilength sheets may be varied in character, and two constructions for effecting this result are illustrated.

Referring more particularly to Fig. 1, the sheets after passing between the cutting cylinders 12, 13 are forwarded beneath a guide, as- 18, to a roll 19 provided with a nipping jaw 20 backed up by a spring rod 21 of the usual type. This roll 19 cooperates with a roll 22 provided with the usual tucking blade 23 which inserts the edge of the sheet into the bite of the jaw 20.. To insure that the edge of the sheet gets into the nipping jaw 20, there may be employed a pivoted guide, as 24, hung on a shaft 25 which is operated through an arm 26 by a cam 27 on a shaft 28. With this construction, the lead ing end of the multilength sheet is taken by'the nipping jaw,-the guide 24 being dropped to insure this,and the sheet carried around by the roll 22 At about the time the nipping jaw takes the leading 'end of the multilength sheet, the sheet is severed, and, as the second part-of the sheet comes into proper position, the sheet which has been carried around by the roll 22is laid upon it,'the nipping jaw being actuated to release the sheet. To insure the forwarding of this sheet, after the nipping jaw has released it, 'a roll, as '29, may be employed, this roll being mounted on a shaft '30'hung in arms 31 supported on brackets 32 on standards rising from the frame. When the sheets have been thus superposed, they are, in the particular machine illustrated in this figure, forwarded'by-the rolls 19, 22,'the position of the guide24 being shifted to permit this,into the bite of rolls 34, 35, which deliver the sheets for assemblage with the web sheets formed by the cutting cylinders 3. The roll 35 has cooperating with it a roll, as 36, these rolls operating not only to receive and forward the web sheets which are delivered to them from the cuttin cylinders 3, but also the inset sheets re erred to. The roll 35 is, in the particular machine shown, provided with a cut away part 37, the purpose of which will be hereinafter explained.

In machines embodying the invention in Y its best form, the mechanism for assembling Ithe product will include a sheet receiving cylinder 38 which, as shown, is a three-part collecting cylinder. This cylinder, when j employed, will, in the best constructions embodying the invention, be provided with these sheet taking and holding devices may be varied, they will, when a collecting cylinder of the character referred to is employed, in the best constructions embodying the invention, comprise two sets of grip- 1 pers, a-set for taking the product presented to the cylinder and a second set for-holding the product while the first set is taking, so as to insure the proper register of the superposed collected products. In the particular construction illustrated, the product is taken by a set of grippers 40, these grippers being I mounted on a shaft 41 provided with an operating arm 42, as usual in gripper con- ;structions, a roll on the arm 42 being arranged to contact at proper times with actuating cams. In the particular construction illustrated, the roll on the arm 42, as I the grippers approach the taking point, contacts with a cam 43 which operates to rock 5 the shaft 41 and open the grippers, so that the product presented to the cylinder may 1 be taken by them.

The holding grippers before referred to are indicated at 44, these grippers belng in turn mounted on a shaft 47 having an op- .erating arm 48 attached thereto. The shaft 45 may have an operating arm for opening the grippers and a spring for'closing them, as common in gripper constructions, the illustration of these parts being omitted in the interest of cleai-ness. The arm 48 carries a roll which contacts with a cam 49 fixed on the frame of the machine. For convenience, this cam may be located at the point at which the sheets are to be finally delivered. With the construction so far described, the grippers 40 take the sheets after they pass between the rolls 35, 36 and carry them on around the cylinder 88, the sheets being laid over the tops of the grippers 44. As the cylinder 38 rotates, the roll on the arm 48 of "the shaft 47 which operates the grippers 44 strikes the cam 49 and withdraws these grippers from under the heads of the sheets whlch have been taken by the grippers 40,

, after which the grippers 44 closedown upon mounted on a shaft 45 supported in arms 46,

the sheets so that the sheets are held by sheets, these both setsof grippers. As the cylinder continues its rotation, the roll on the arm 42 strikes the cam 43 and opens the set of rip.- pers to take the fresh lot of sheets elivered by the rolls 35, 36. This operation continues until it is dwired to deliver the sheets,

'at which time both sets of grippers will be chine illustrated, are delivered to a set of a forwarding tapes A switch, as may be emplo ed toinsu e delivery of the h Shoul it be desired to produce a product having a cover, the covers may be fed in by rolls 56, 57, the roll 57 having a raised surface 58 to enable the coversto be intermittently fed. The roll 57 delivers the covers in such a way that the head of the cover is in register with the sheetswhich have been delivered by the rolls 35, 36, the cover and these sheets being taken by the grippers 40.

rying a stapling mec Should it be desired to secure the product together by staples, this may be accomplishedby providingla roll 59, this roll caranism of ordinary construction, indicated at 60, and cod rating with the cylinder 38. Stapling mec anisms desi ed to insert the desired number of stap es are well-known in theart and a specific description of such mechanism is unnecessary.

It has heretofore beenstated that the roll. 35 is provided with a cut-out portion 37. In order to give the grippers time to operate between the successive sets of sheets presentedby the rolls 35, 36, it is desirable to space the sheets apart. This may be done by causing the rolls 38, 57 to run at a slightl accelerateds'urface s eed as com-pared wit the rolls 35, 36, and t e cutting away of the roll 35 as indicated at 37 enables the sheets, after being taken by the grippers 40, to be pulled away from the rolls 36, thus spacing the sheets, as indicated in Fig. 1.

b After the sheets have been stapled, they may, if desired, be subjected to the operation of a folding mechanism. While they may be folded by any desired mechanism,

in the construction illustrated, a striker blade 61, o erated in the usual manner, is

. illustrated or this purpose, the sheets being presented to the striker blade by thetapes 54 before referred to and by a, coiiperatmg set of tapes 62, as is common inconstructions of this character The construction illustrated in Fig. 2 shows a modified form of the mechanism for eets.

' is wellmanner by a construction well understood in 1 the art and not illusrated. This switch directs the headof the sheet between a pair of rolls 67,68, from w hich the sheet passes.

between a pair of. r0115 69,70. The roll 63 may be cut away, as in iicated at 71, to give space for the operatit n of the switch 65. The rolls 69, have slightly slower surface s eed than the roll Wh1Cl1 precede them, viz., t I e rolls 63, 64 anl 67 68, for the purpose of slowing down he sheet. When this construction is adopted the roll 69 may be cut away, as indicated til 7 2, so that no posh tive feeding action of this roll takes place until after thetail of the sheet has passed between the rolls 67, 68 after which the high portion of the roll 69, 'ogether with the roll 70, takes control ofeth: sheet and forwards it. As shown, the she at, after it leaves the rolls 69 and 70, is talen control of by an" ar guide 73 mour ted on'a cross-rod 74 an by a roller 75, these parts serving to.v

direct the sheet downw ard to a pair of rolls Afterthe multilengt h sheet has been severed and the first part directed upward, by

the switch 65, to the. rolls 67, 68, and the agencies succeeding th am, as describedfithe f ing position of the switch 65 is shifted, li

the tail of the first she at-upward, as shown, the cut-away portion 7L of the roll 63 facilitating this operation. The second half of the sheet is directed do vnward by the switch around the roll 64 and between rolls 78, 79.

which serve, to direct his. sheet to the rolls 76, 77 beforereferred so where it meets the head of the first sheet. Tapes, as 80, passin around the rolls 77 and 79, maybe employ 'for the purpose of su' porting the sheet in lls17 8, 9

its transit ,from the rc to the rolls 76, 77. The sheets tl us assembled by the rolls 76, 77 are sent forward by these rolls 1 to the rolls 34, 35 wh are they meet theinus coming web sheets fram the cutting rolls before described.

I The remalnder of t] Le mechanism basal: ready been described connection with Fig, 1 andfurther dest ription of it is, therefore, unnecessary.

The gearing by which the operation of the several parts is efir cted is indicated, but as the o eration of gea ring of this character own, it is uinecessary to burden the specification with t 1e descri tion thereof.
