IMPROVEMENT l-N SHEET-DELIVERING APPARATUS FOR PRINTING-MACHINES.

Specification forming-part of Letters Patent No. 197,700, dated November 27, 1877 application filed November 22, 1877.

Toallv whom it may concern:

Be it known that I, STEPHEN D. TUCKER, of the city, county, and State of New York, have invented an Improvement in Sheet-Delivering Apparatus for Printing-Machines, of which the following is a specification:

This invention relates to that class of delivering mechanisms for printing machines wherein two or more sets, each consisting-of two or more sheets, (as the inside and outside sheets of a newspaper composed of twoseparate sheets,) are collected oraccumulated upon a rotating carrier, and said sets of sheets delivered therefrom in succession at the same or different points of the said carrier; and it consists, essentially, of a sheet-delivering carrier, having a circumference which is equal to the length in their line of travel of the number ofsheets to be collected or accumulated together in a set, plus one, upon its surface; or'

its circumference may be a multiple of said number,plu s one. This cylinder is provided with collecting oraccumulating mechanisms whereby sheets delivered in succession upon it will be associated in sets consisting of twos, threes, fours, and so on, each of which sets comprises the separate sheets, forming a complete whole, and, in combination therewith, a correspondingnumberoffoldin-g-blades,whereby said sheets may not only be associated in sets, but said sets of sheetsbedelivered folded.

The invention also embraces details of construction and operating mechanisms, fully herein-after pointed out.

An apparatus embodying the invention is, illustrated in the accompanying drawings, in which Figure 1 is a right-hand elevation; Fig. 2,. aleft-hand elevation; Fig. 3, a front-end ele- Figs. 4 and 5 are views of part of the mechanisms for operating the foldingblade cams Fig. 6-, a longitudinal section of the apparatus, asseen from the left-hand side, Fig. 7., a similar view of the delivering.- carrier; Fig. 8, detail views of arevolving griper-opening cam; and Fig.9, a longitudinal'section of a delivering-carrier combined. witha separate folding mechanism.

Though this apparatus is particularly de-' signedtobe attached to and form a part of a rotary web-perfecting printing-machine, in

V which the type-cylinders carrytwo forms, printin-g,respectively, the inside and outside sheets of'a newspaper, it may obviously receive and manipulate sheets fed to it by hand or mechani-v cally, and whether blank, as from a paper making machine, or printed, as from a print- As here shown, the cylinders ing-machine. 4748, one of which supports a cutting-blade,

49, and the other of which is provided with a cutting-slot, 50, are supposed to formapart.

of a rotary web-perfectin g printing-machine.

They are geared together by toothed wheels. 70 74, so as to run in unison, and they will be driven (preferably by gearing connecting them with the printing-machine) so as to runin unison with the type-cylinders of the printing- 1 machine, and the male cylinder 47 will have a circumference equal to one-half the size of said type-cylinders.

The delivering-carrier 60,. while provided I with mechanisms which adapt it to collect or accumulate three'separate sets of sheetsupon its surface, each of which consists of two sheets laid one upon another, may, also, and, preferably will, be furnished with means for folding said bodies of sheets, thus becoming a. combined accumulating; and folding mechanism, as. in the, Patent No- 191,494, granted to S. D. Tucker, May-29, 1877 5 but it may be an accumulating mechanism only, and de- .pl-ained.

This delivering-carrier 60,. which is herein shown in the form of a, cylinder, is furnished with'three. sets of gripers, 3-5 7, on shafts 21 22 23, the oflice of which is to seize, convey, and release the sheets at proper times.

of whichis provided with a friction-roller, as

9, to ride; over ,thecams, to open the. .gripers, and its other end is furnished with a rod and i spiralspring '46, to close them. This carrier is also furnishedwith three rotating double foldingblades, 106 107 108,0n shaftsl 2 4,

which blades co-operatewith folding-rollers arranged. in pairs, as 31 82 and 91 92, at proper points-of the periphery of the. said carrier 60.

The said gripers are arranged at equidistant I These.- griper-shafts 21 22 23 each have on one of their ends an overhanging. cross-head, as 19,. oneend points in the carrier 60, as are the said fold-v ing-blades, the leading edges'of the latter being midway between each two sets of gripers, each set of gripers-being thus adapted to receive a sheet, and hold it upon the carrier in position to .be manipulated by an appropriate one of the folding-blades. Y j

The mechanisms actuating these foldingblades are arranged to operate them at two deliveringp oints from the carrier 60, as will be explained, which said points of delivery are occupied by the pairs of folding'rollers 81 82 and 91 92. These folding-rollers are driven by a toothed wheel, 78, fixed at one end of the shaft of the carrier 60, which wheel gears with and drives the pinion 118 on the roller 81, and the pinion 119 on the roller 91, and these inturn gear with and drive the pinions 120 121 on the companion rollers 82 92. The carrier has a toothed wheel, 72, secured to the outer end of its shaft 20, by which it is rotated through the intermediate toothed wheel 73 by the toothed wheel 74 on the shaft of the cuttingcylinder 48, and these wheels 72 74 are so proportioned to each other that the cutting-cylinders will make three revolutions to one of the point.

The sheets are conducted to the carrier 60 by means of endless carrying-tapes 42 52, the set 42 of which pass around the roller 80, up to and partiallyaround the said carrier, between the folding-rollers 81 82, and return over the roller 83 to theroller 80. The set of tapes 52 pass around the roller 90, up to and around the roller 84, and return to the roller 90, and these two sets of tapes are caused to run in unison by means of the toothed wheels 75 76, which gear their rollers together. A guard, 33, covers that portion of the carrier 60 which lies between the rollers 82 91, and a set of tapes, 43, running over the rollers 85 86, are driven by means of a pinion, 61, fixed upon the shaft of the roller 85, which pinion gears intoand is driven by the toothed wheel 78 on the shaft 20 of the carrier 60. These tapes 43 cover that portion of the carrier 60 which lies between the point where the gripers release sheets which are to be folded through the rollers 9192 and the point of reception for the sheetsupon the carrier. This point of reception for the sheets is occupied by aconductor, 32, whose upper surface is aligned with the tapes 42,. and whose inner surface coincides with the periphery of the carrier 60.

.The diameter of the carrier 60 is somewha greaterthan three times that of the cuttingcylinders, so that its circumferential speed is a little greater than theirs, and the carryingtapes are driven at the same speed as the carrier by. the toothed wheel 71, secured to the cutting-cylinder 48, driving the toothed wheel 117, fast upon the shaft of the roller 90, through the intermediate toothedwheel 77, the wheels 117 71 being so proportioned to each otheras to accomplish this. i i Z The web of paper (herein shown as passing from a reel, will be led from the printingmachine directly through the cutting-cylinders 47 48, and, as the cutting-blade 49 in the cylinder 47 has portions of its edge removed at certain places, as 31, the web will be but p'artially severed on the lines dividing it into sheets, thus being left joined at those places.

As the partially-severed web enters between the carrying-tapes 42 52, it is forced to run at the speed of the cutting-cylinders until its leading edge, guided by the conductor 32, is

directed onto the carrier 60, where it is nipped between the tapes 42 and the periphery of the said carrier, and at the same time is seized by one set of its gripers, and these instrumentalities carry it forward at an increased rate of speed, and detach or tear it apart upon its line of partial severance, which has then just entered between the tapes 42 52. j

Each set of gripers as it approaches the point of reception of the sheets to receive the leading edge of an incoming sheet, then undetached from the web, is opened by the stationary griper-cam 45, over whose surface a friction-roller on its cross-head is forced to ride, and closed (by the spring-rod 46) in passing off from said cam 45, to seize, aid in detaching it from the web, and carry the sheet aroinid upon the carrier, until said set of gripers is again opened by the cam 45 to receive a second sheet upon the first, and carry both around upon the carrier until said gripas .are again opened.

Each set of gripers is at proper timesalso of the toothed wheel 69, which runs on a stud,

49, and is driven by thesame pinion 62. Now, the proportion of the pinion 62 is to the wheels 68 69 as 1 is to 1%, so that the carrier 60 will i make one and one-third revolution to one revolution of the revolving cams 41 51, and, i as the carrier 60 is provided with three -sets;of

gripers, 3 5 7, it follows that the revolving cams 41 51 will each make one revolution to each one and one-third revolution of the carrier and to each fourth set of gripers that passes them; but these cams are so timed as to be brought into position to act alternately,

on the sets of gripers passing. them, whence it follows that each second set of gripers will be alternately opened by the cams 41 51,while the intermediate setswill pass byunoperatedi The folding-blade shafts l 2 4 each haveon one of their ends an overhanging cross-head,

as 11, each end of which is furnishedwithfric tion-rollers, as 6 8, which ends, as the carrierrevolves, alternately comc'into contact with a flying cam, or 17 and a stationary cam, 16 or 18, the co-operation of which cams willcause the folding-blades to make a semi-rotation, and fold the sheets overlying them into the nip of the folding-rollers 81 82 or 91 92, which operation is particularly described in a companion application filed November 6, 1877.

On the outer end of the shaft 20 of the carrier 60, opposite to that supporting the wheel 72, a broad-faced pinion, 63, is secured, which pinion gears into and drives the toothed wheel 66, fixed on the shaft 24, and also the toothed wheel 67, fixed on the shaft 25. The outer ends of these shafts are supported in a bracket, 104, and they run throughithe side frame, and on their inner ends they each carry one of the flying cams 15 and 17. These shafts 24 25, in addition to their revolving motion, have a lateral reciprocating motion imparted to them, for a purpose which will be presently explained. This lateral reciprocating motion is effected by the broad-faced pinion 63, driving a toothed wheel, 79, which runs loosely on a stud, 38, and has a grooved cam, 56, fixed to its outer side. A vibrating lever,

53, is pivoted nearits centervto a stud, 36,

and its short arm enters the groove of the cam 56, while its long arm engages with a groove, 55, cut in the hub of the wheel 66, so that, as the cam 56 revolves, it causes the wheel 66, its shaft 24, and the flying cam 15, on .its inner end, to reciprocatelaterally. A similar vibratin g lever, 54, also engages with the grooved cam 56 and with a groove, 57, in the hub of the wheel 67, and thus gives a similar reciprocatin g motionto the shaft 25 and its flying cam 17. Butthis pinion 63 is of such a width that the wheels 66 67 can move laterally with-i blades to be projected between'the foldingv rollers in performing the folding operation. The flying cams are withdrawn or moved outward beyond the path of travel of the frictionrollers 6 or 8, so that the folding-blades may pass them without being operated.

The proportion of the pinion 63 to the wheels 66 67 79,is'as 1 is to 1 so that the carrier will make one and one-third-revolution to one revolution, and also to one reciprocation of the flying cams 15 17,in' and out of the path of travel of the said friction-rollers v6 and 8. Now, the carrier 60 has three folding-blades, so that, as'it revolves, four blades will pass by during each revolution and reciprocation of the flyin g cams. But these flying cams are, by the posi:

tion of the levers 53 54 in the cam 56, caused to reciprocate alternatelythat is to say, each folding-blade, as it passes, will be operated by the'flying cam 15 or 17 to double the sheets overlying it into the nip of a pair of foldingrollers, 81 82 or 91 92. This operation, it will be observed, coincides with the opening of each second set of gripers to liberate its sheet for the action of said folding-blades. Furthermore, the movement of the griper-cam 41 is so timed as to open the gripers just as the fly-f ing cam 15 begins to operate to double the sheets they carry into the nip of the pair of folding-rollers 81 82, and, in like manner, the movements of the griper-cam 51 and flying cam 17 will correspond to deliver the next second set of associated sheets to the pair of folding-rollers 9192.

In order to a clearer understanding of the operation of this apparatus, its manipulation of the sheets will now be described. For this purpose, the mechanism will be assumed to have been in operation, so that the carrier 60 will be receiving sheets in sets uponits surface, and discharging the same.

When in the position of Fig. 6, the revolving cam 51 will have been so rotated as to have intercepted and opened the gripers 5 to release the set of sheets A B carried by them, and the flying. cam. 17 will have been recipro-f cated inwardly, and revolved so as to intercept the friction-roller 6 and partially rotate and project the folding-blade 107, as in Figs. 1 and 6, to double said set of sheets into the nip of the folding-rollers 91 92, which rollers will deliver said set of sheets'to the tapes 122 123, which will deliver them once folded. The sheet B, held by the gripers 7, will be carried around with the carrier as it revolves, thefolding-blade 108 not being projected at this time when passing-the rollers 81 82, for the reason that the flying cam 15 then stands in its outermost position, as in Fig. 3; andthe said folding-blade 108 will also pass the rollers 91' 92 without being projected into their nip, for the reason, that the flying cam 17 will at that time have also been reciprocated into its outermost position, (see Fig. 7,) the cams 41 51 also being out of position to open the gripers 7. But as the folding-blade 106, which .underlies the set of sheets A B held by the gripers 3, arrives at the folding-rollers 81 82, it will be projected to double said set of sheets into their nip by the operation of the flying cam 15, which has then been reciprocated into its innermost POSltlOll'tO thus actuate it. The revolving cam 41 will also .have moved into position to open the gripers 3 and release said set of sheets. be receiving 'a sheet, B, which will pass the rollers 81 82 without being folded by the fold-. ing-blade 107 as the flying cam 15 will their stand in its outermost position, and which sheet will also pass the folding-rollers 91 92 without beiiig folded through them by the said folder 107, the cams 41 51'thcn being out of position to open the gripers5.

At this time the gripers 5 will The next sheet, A, will be received by the gripers? and laid upon the sheet B, and this set will pass the rollers 81 82, and be folded through the rollers 91 92 by the folder 108, as was the first set described as undergoing the folding operation, and the operations described will be repeated.

It is to be observed that, in order to associate alternate sheets-that is, such as, differingfrom each other and taken together, form a complete whole, as the inside and outside sheets of a newspaper-in proper sets upon the carrier 60, it is necessary to provide it with a circumference which is equal to the length, in the direction of their travel, of

three sheets plus the necessary space between the heads and tails of each set to provide for the operation of the gripers, or to prevent the sheets'interfering with each other, for the reason that by such an arrangement only can non duplicate sheets passing in succession onto the carrier be laid one upon the other, and be properly associated in sets thereon;

and this is equally true whether the" said.

sheets are to be folded, as has been described, or delivered unfolded, as will be described.

When this carrier is to collect and fold alternate sets composed of two four-page sheets, its circumference must be large enough to hold singly three such sheets, asv before explained, by reason of the manner in which the forms are placed on the type-cylinders, where- T by an inside and an outside sheet will always come alternately. Thus an outside sheet will always be collected upon an. inside one. The

carrier must also have three folding-blades and three sets of gripers, and the folding and griper cams must be arranged to operate only as every second folding-blade passes, as has been hereinbefore explained, for every second sheet is an outside one, and has an inside sheet beneath it, and it is their folding-blade that, as it passes, is operated by the-cam to thus fold the complete pair of sheets into the nipoi' the folding-rollers. The alternate sheets that are missed by the folding-blades are at that time inside sheets, which, at their next revolution, will receive an outside sheet on top of them, and will then be i'olded in like manner.

If it is desired to fold the sheets singly, in-

stead of in pairs, the grooved cam 56 must be replaced by one that will at each revolution give two "complete reciprocations 'back and forth to the flying cams. The flying cams are replaced by others that willact twice to each of their revolutions, as illustrated in Fig. 32 of the Patent No. 191,494, granted to S. D. Tucker, May 2's, 1877. Each flying cam will then act uate every second folding-blade" that passes, and the two cams together will operate all the folding-blades, andhence, while one folding- 1 blade will operate at the folding-rollers 81 82, the next will operat-e at the 'foldin '-rollers 91 92, the nextat the rollers 81 82, nd so on, whereby the sheets received upon the carrier in the order 1, 3, 5, &c., will be folded through It is obvious that if it is required to associate.

in sets upon and deliver from a carrier, as 60, three, four, or any other number of non-dupli: cate sheets fed in succession thereto, said delivering carrier must have a circumference equal to the length of the number of the sheets i to be so collected in a set, plus one, upon its surface, and delivered therefrom, and if these sets of sheets are to be folded by foldingblades supported by said carrier, then said folding blades must correspond in number with that of the sets of sheets upon the surface of the carrier, and these folding blades must betimed to fold the said sets of sheets, when the same are completed in their number of sheets, a l-y ternately through the lbldingQrOllers 81 82 and 9192; but it may be preferable to increase the number of these folding-rollers as the number of sets of sheets is increased. .i

Duplicate sheets to any convenient number as, say, 10, 20, 25-may becollected in sets and folded together, thus formin g packages folded and counted ready for delivery. e

, This delivering-carrier may, however, perform only the oiiice of collecting or associating said sheets in sets, and have the same directed to an independent folding mechanism. This is illustrated in Fig. :9, wherein is shown a delivering-carrier adaptedto collect or associate non-duplicate sheets in succession in sets of.

pairs upon its surface-such as,"say,two four- ,page sheets to form an eight-page newspaper.

Its circumference must be large enough to take on singly three sheets, for the same reasons that are explained in the case of the folding accumulating carrier hereinbefore described, and this carrier may deliver its collected inside and outside sheets in pairsto a folding mechanism to be folded, or to asheet-flier to be piled flat. Such an apparatus is shown in Fig. 9, where 99 is the delivering-carrier, provided with three sets of gripers, 94 9596, a seize and carry forwardthe sheets, and with l a switch, 12, to discharge them at, the proper.

The series of endless conducting-tapes 42, stretched from the roller 80, near theupper cutting-cylinder 47, extend partially around. the carrier 99, under the roller 64 to the foldr ing-carrier 109,,under the folding-rollerr35,

This folding-carrier is provided with two sets of gripers, 13 14, and two rotary folders, 27 28. The blade 27 will fold its sheets into the pair of folding-rollers 34 35, and the blade 28 will deliver its sheets to the pair of rollers 58 59 by the co-operation of flying and stationary foldingcams, as already described in a patent granted to S. D.Tucker, December 14, 1875, No. 171,196. As the foldin g-blades must operate but once to each revolution of the folding-carrier, the flying cam will run turn for turn with the carrier; consequently, when the blade 27 passes the rollers 58 59, the point of the flying cam will at that time be turned toward the center of the carrier, and the blade will passon unoperated; and the same will be the case when the blade 28 passes the rollers 34 35-. Thus each blade will always deliver its sheets into the same rollers and into no others. A grooved cam, 102, is secured to the shaft 29 of the foldingcarrier, and imparts motion to the switch 12, and through the link 103 to the griper-opening cam 110, by means of a connecting-rod,

105, one end of which is jointed to an arm,

111, on the switch-shaft, and the other end is forked to embrace the shaft 29 of the foldingcarrier. This rod 105 is provided with a pin, 112, that runs in the groove of the cam 102, and thus gives motion to the griper-cam and switch. The shape of the cam 102 is such that it will bring the griper-cam and switch into operation as each second set of gripers approach it, and the gripers will be opened and the points of the switch enter the grooves in the cylinder through the space between the sets of sheets,

and thus direct the sheets off, and the cam is so timed that these gripers are just the ones that then carry complete pairs of inside and outside sheets.

As the pairs of sheets are directed off from the carrier by the switch 12 they are conducted by the guides 113 and assisted by the tapes 42 to the foldm g-carrier, where they are seized by the gripers 13, which have been opened by the stationary cam 114. The sheets are then seized and carried around until the gripers are intercepted by the vibrating griper-cam 115, which opens them just in time for the folding-blade 27 to fold the sheets into the rollers 34 35.

The griper-cam 115 is vibrated by an eccentric, 116, on the shaft 29 of the folding-carrier, so that at each revolution of the carrier it is moved out to open the gripers 13 and drawn in to escape the gripers 14. These latter are opened at the proper time for the operation of the blade 28 upon its sheets by the stationary 'cam 114. It will be seen that when sheetscollected in pairs are to be folded they are always seized by the gripers 13, and folded bythe blade 27 into the rollers 34 35, the other blade and set of 'gripers working uselessly, or they may be rendered inoperative. But when it is desired to fold the four-page sheets singly, the switch 12 and griper-cam 110 are detached from the cam 115, and made stationary, so as to guide off each sheet singly to the foldingcarrier, where they will be seized in succession by the gripers 13 14 and folded into the rollers 34 35 and 58 59, alternately.

The folding-carrier 109 may be of but onehalf its present size, and have but one foldingblade and set of gripers, and one pair of folding-rollers. In that case it will make three revolutions to the collecting-carriers one, so that when folding the sheets collected in pairs every second revolution will be an idle one; but when. the sheets are to be folded singly it will fold one at each revolution. Three or more sheets may be thus collected and folded, and in so adapting it the carrier must always be of sufficient size to hold the number of sheets to' be collected in a set, plus one, as before described.

The once-folded sheets as they issue from I the folding-rollers of this apparatus maybe again folded, either parallel with or at right angles to the first fold. This may be done by either of the rotary mechanisms herein described, or by the constantly-rotating blade, (shown in Figs. 17,, 18, 22, 23, of the Patent granted to S. D. Tucker, December 14, 1875, N0.171,196, or as in No. 191,494, May 29,187 7,) or by reciprocating blades.

' The accumulating carrier or cylinder 60 or 99 will preferably be provided with gripers, as before explained,to seize and retainthe sheets received upon it 3 but said gripers maybe dispensedwith.

It is apparent that longitudinal or transverse lines of paste may be applied to the upperside of the inside sheets, or to the under side of the outside sheets, at proper points thereof, according as said sheets, when associated, are to be subsequently folded after receiving their first fold by the folding blades of this apparatus.
