WEB-PERFECTING PPdNTlNG-MACHWE.

SPECIFICATION forming part of Letters Patent No. 317,740, dated May 12, 18:85.

Application filed January 13, 1882.

To all whom it may concern.-

Be it known that I, LUTHER G. GRowELL, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Rotary Web-Perfecting Printing-lilachines, fully described and represented in the following specification and the accompanying drawiu gs, forming apart of the same.

This invention relates to that class of machines which are adapted to print both sides of a moving web of paper, sever the same into short lengths or sheets, and then deliver the same as a folded product in suitable form for the carrier or for mailing, and which are knownin the art as rotary web-perfecting printing-machines.

The invention relates more particularly to that class of these machinesin which each formcylinder is provided with a plurality of immession-cylinders, so that two or more webs can be printed simultaneously from the same setbf plates or forms.

One part of the invention consists in the combination, with two printing mechanisms set at an angle to each other, of means for leading a web of paper to the first mechanism from the side adjacent to the second mechanism, a web-turner arranged to turn and guide the web from one to the other, and means for leading the printed web from the second mechanism upon the side adjacent to the first mechanism.

The invention also includes the combination, with a web-printing mechanism which is arranged to perfect a plurality of webs and deliver them at the same side of the machine, of a single cutting and folding mechanism arranged to operate upon both webs.

The invention also embraces various details of construction and combinations of parts both in the printing and delivery mechanisms, all of which will be hereinafter fully explained, and particularly pointed out in the claims, in connection with the accompanying drawings, in w-hich Figure 1 is a plan view of a mechanism embodying those parts of the invention which relate to the printing of the web or webs. Fig. 2 is a sectional elevation of the same, taken upon the line 00 m of Fig. 1. Fig. 3 is a (No model.)

similar view taken upon the line y y of the same figure, showing also in side elevation a modified form of the delivery mechanism. Fig. 4 is a sectional elevation of the delivery mechanism, taken upon the line as a: of Fig. 5. Fig. 5 is a sectional elevation of the same, taken upon the line 0000 of Fig. 4. Figs. 6 and 7 are detail views upon an enlarged scale, showing the manner of operating the pins upon the cutting and folding cylinders. Figs. 8,9, and 10 are similar views, also upon an enlarged scale, showing the pins as operated in a slightly-different manner, and illustrating also the operation of the cutting and folding cylinders in associating sheets. Fig. 11 is a plan view, upon an enlarged scale, of the supplement-introducing mechanism. Fig. 12 is a sectional elevation of the modified delivcry apparatus hereinbefore referred, to, the

same being taken upon the line 2 z of Fig. 3. Fig. 13 illustrates details to be hereinafter referred to.

Referring particularly to Figs. 1, 2, and 3, it is to be understood that the printing mechanism therein shown consists of two groups of mechanism. The first of said groups is mounted in suitable bearings at the left of the machine, as seen in Figs. 1 and 2, and consists of at'orm-cylinder, 1, and two impressioncylinders, 2 and 3, which are arranged one above the other, the cylinders l and 3 being in a vertical line, while the upperimpressioucylinder, 2, is placed a short distance to the right of this line, as seen in Fig. 2. This arran gement is made in order to allow space for the introduction and removal of the plates but it is not absolutely essential, and may be varied as may be found desirable without departing from the invention. These three cylinders are provided with engaging gears 4 5 6, (see Figs. 1 and 12,) by which they are causerl to revolve in unison, motion being communicated to them from a bevel-gear, 35, upon the driving-shaft 36 through a bevel-gear, 33, upon the shaft of the cylinder 2.

The form-cylinderl is provided with two sets of inking mechanism, consisting of the distributing-rolls 8 9, which are supplied with ink from a fountain in any suitable manner, and the form-rolls 10 11, all of which are of the usual construction, and operate to ink the forms in the usual manner.

The second group of printing mechanism is arranged at or substantially at right angles to the first group, and also consists, like the first, of one form-cylinder, 31, and two impressioncylinders, 23 32. These cylinders are placed in the same relation to each other as the cylinders of the first group, and the form-cylinder 31 is also provided with inking mechanisms similar to those described in connection with the cylinder 1. These cylinders are provided, like the cylinders 1 2 3, with engaging gears, (see Fig. 1,) by which they are caused to rotate in unison, motion being communicated to them from the bevel-gear 35 upon the driving-cylinder 36 through a bevel-gear, 34, upon the shaft of the cylinder 23. To the printing mechanism thus organized there are led two webs of paper, 12 13, which are contained in rolls 1415, mounted upon spindles 16 17, which are supported in any suitable manner at the right of the machine, as seen in Fig. 2. The web 13 from the roll 15 passes over a guide-roll, 19, and thence downward between the impressioncylinder 2 and the form-cylinder 1, in passing which it is printed upon one side by the plates upon the cylinder 1, after which'it passes upward around the cylinder 2, and thence backward toward the point of starting, it being printed upon what is now its upper side. As theweb is led backward toward its point of starting, it is led downward around a turnin g-bar, 20, which is arranged obliquely across the path of the web, as shown in Figs. 1 and 2, so as to be turned at right angles to its previous path of travel. After passing the turning-bar 20, the web, with its printed side now downward, is led around the impression-cylinder 23, and between it and the form-cylinder 31, and thence forward above a guide-roll, 37, and across its path of travel in entering the machine.

The turning-bar 20, which, as here shown, consists of a simple bar of wood or metal, although it may be formed of a plate provided with an oblique turning-edge, is hinged at one end by a ball-and-socket or other universal joint, 22, to a bracket, which is secured to the frame ofthe machine, as shown in Fig. 1, while its opposite end is supported in an adjustable bearing secured to the opposite side of the frame-work. By this means the turnercan be swung in any direction, so that it can be set at any desired angle of relation to the cylinders 2 and 23, so as tocause the Web to be properly directed fromthe first to the second of the groups of printing mechanism.

The adjustable bearing just referred to, in which one end of the turning-bar 20 is supported, consists of acollar, 24, which receives the end of the turning-bar and. is provided with a stem, 28, (see Fig. 13,) which enters a suitable bearing in the bracket 21, where it is secured in position by set-screw 25, passing through the bracket and impinging against said stem. By loosening the set-screw 25 and moving the stem 28 up or down, the vertical angle of the turning-bar can be adjusted with said cylinder and the form-cylinder 1.

relation to the printin g-cylinders. The bracket 21 is secured to the frame of the machine by bolt27, passing through a slot, 29, by which arrangement the bracktt is capable of being shifted upon the frame of the machine so as to adjust the horizontal angle of the turningbar with relation to the printing-cylinders. The web 12 from the roll 14 is led into the machine directly beneath the web 13, and, after passing above a guide'roll, 18, is conducted upward around the impression-cylinder 3 of the first group of printing mechanism, and between In passing between these cylinders it is printed upon its upper side in the same manner as has already been described in connection with the web 13. After being thus printed, it is led backward toward the roll 14 and downward around a turning'bar, 41, which is constructed and arranged in precisely the same manner as has already been described in connection with the bar 20, and by which the web is turned at right angles to its previous path of travel, and directed to the second group of printing mechanism. After leaving the bar 41, the web is led outward between the form and impression cylinders 31 32, thence down ward around the impression-cylinder 32, and inward above a guide-roll, 42, and thence forward across its path of travel in entering the machine.

Referring now particularly to Figs. 4 and 5, the operation of the delivery mechanism in disposing of the product'of the two webs will be described. The web12, as it reaches the side of the machine, is led upward around a guide and register roll, 43, thence forward over a second guide and register roll, 44, onto the face of a longitudinal folder, 45, while*the web 13, as it arrives at the side of the machine,

is led upward around a guide and register roll, 7

38, thence forward directly above the web 12, over the roll 44, and over a similar roll, 39, onto the face of a longitudinal folder, 40.

It is to be remarked in passing that the rolls 43 38 will in practice he made adjustable in position, so that the travel of the webs may be properly regulated to secure accurate registration with the cutting mechanism, which will be hereinafter described. 1

The longitudinal folders 40 45 may be of the construction shown in United States Letters Patent No. 233,997, or of any other approved form which is adapted to longitudinally fold a'continuouslymoving web or sheet of material. These longitudinal folders 40 45 are arranged one in advance of the other, (see Fig. 4,) so that the folded webs 12 13, as they pass from the surface of their respective folders, are received and fed forward by the single pair of rolls 46 47. The perfected and longitudinally-folded webs then pass to the transverse cutting and folding mechanism, which will now be described. This mechanism consists of two cylinders, as 48 49, which are provided with cutting and folding devices, and of a pair of cooperating longitudinally-folded webs.

folding-rolls, as 58 59, (see Fig. 5,) all of which cylinders and rolls are of sutficient length to receive side by side and operate upon the two The cylinders 48 49 are geared together, and are driven from the gear 5 of the'form-cylinder 1 through the intermediates 54 55. The folding-rolls 46 47 and 58 59 are or may be driven through intermediates connecting them with any appropriate one of the before-mentioned gears. These devices thus form a single delivery mechanism capacitated to receive and dispose of the products of the two printed webs.

Referring now particularly to Figs. 6 to 10, inclusive, it will be seen that the cylinder 49, which in the case shown is of the same size as the form-cylinder, which may carry circumferentially two duplicate sets of forms, is provided at opposite points of its periphery with corresponding sets of sheet-holdin g pins 69 70. These pins are pivoted to the ends of arms 71 72, carried by rock-shafts 73 74, journaled in the ends of the cylinder, and are arranged so as to be moved in and out through holes in the surface of the cylinder. The rockshafts 73 74 are provided with springs which normally hold them in such position that the pins 69 70 are drawn within the cylinder and carry rock-arms 79 75, through which the shafts are rocked to protrude the pins. When, therefore, the leading ends of the webs, after passing between the rolls 46 47, reach the bite of cylinders 48 49, the revolution of cylinder 49 will, as shown in Fig. 6, bring the stud or roll 76 of the arm 75, carried by the rock-shaft 74, into contact with the stationary cam 77, thereby rocking the shaft 74, and causing the pins 70 to protrude beyond the surface of the cylinder and impale the leading ends of the webs, as shown in Fig. 7. The webs thus impaled upon the pins 70 will be carried around upon the surface of cylinder 49, as shown in Fig. 8, until the cylinder has made one-half a revolution, at which time the knife 65, carried by the cylinder 48, coacting with recess 81 in cylinder 49, severs the webs. At the same time or immediately before the webs are severed the stud or roll 80 of rock-arm 79, carried by rock-shaft 73, comes into contact with the stationary cam 77, thereby causing the pins 69 to protrude and impale the webs just in the rear of the point of severance, as shown in Fig. 8. Shortly after the webs are severed by the blade the stud or roll 76 will pass off the cam 77, as in Fig. 9, thus allowing the spring heretofore referred to to retract the pins and release the sheets, which are immediately folded between the rolls 58 59 by the rotating folding-blade 78. The freshly-cut ends of the webs are held by the pins 69 and carried around onehalf a revolution with the cylinder 49, and are then released in like manner and folded between rolls 58 59 by the rotating folding-blade 82, the blade 65 and pins 70 having in the meantime again come into operative position with respect to the webs to repeat the operation just described.

The rotating folding-blades 78 82 are constructed and operated in the usual manner and require no specific description 5 but it may be stated that any of the well-known modes of operating folding-blades in a rotating carrier may be employed.

It is to be remarked that after being folded between the rolls 58 59 the sheets may pass to other folding or to folding and wrapping mechanisms, to be still further manipulated; or they may pass onto a fly and be piled upon a table or fly-board.

In the operation just described it will be observed that the mechanism produces and delivers twice-folded four complete papers at each revolution of the formcylinders, and conse-' quently that each paper contains matter equal to one-half the circumferential capacity of said cylinders. If it is desired to deliver these papers in pairs, it may be accomplished as follows: The cylinder 48 is provided with a set of sheet-holding pins, 62, located just in the rear of the knife 65. These pins are pivoted .to the arms 63 of a rock-shaft, 64, journaled in the ends of the cylinder, and are adapted, like pins 69 70, to move in and out in holes in the surface of the cylinder. The rock-shaft 64 is provided with a spring, the tendency of which is to hold the shaft in such a position that the pins will project beyond the surface of the cylinder. One end of the rockshaft 64 is provided with a rock-arm, 68, carrying a stud or roll, 67, which at each alternate revolution of the cylinder 48 comes in contact with an adjustable cam, 66, carried upon the end of cylinder 49. When the papers are to be delivered singly, as already explained, the arm 68 is forced inward, so as to draw the pins 62 inside the cylinder 48 and make them inoperative, and is there secured in any convenient manner. When the papers are to be delivered in pairs, the arm 68 is released, so that the pins 62 can come into operative position, and one set of the pins upon the cylinder 49 (the set 69, as shown in Figs. 9 and 10) is rendered inoperative. This may be done by removing the arm 79 from the rockshaft, or by turning it to another position upon its shaft and then securing it so that it will not come in contact with cam 77.

The parts being thus arranged, the operation will be as follows: The pins 69 being inoperative, the leading ends of the webs will be impaled upon the projecting pins 62, as in Fig. 9, and carried around upon cylinder 48 until said cylinder has made one full revolution, at which time the knife 65 will sever the webs and the freshly-cut ends, and the ends held by pins 62 will be brought together, as shown in Fig. 10. Just at or a trifle before this time the cam 66 is brought into engagement with the stud or roll 67 of arm 68, and the shaft 64 is rocked so as to withdraw the pins 62, as in Fig. 6. At the same time that the pins 62 are withdrawn the stud or roll 76 of arm 75 comesinto contact with cam 77, and the pins 70 are projected so as to impale the leading ends of both the webs and the severed sheets and carry them around upon the surface of cylinder 49. When they have been thus carried one-half a revolution, the knife 65 will again sever the webs, and, the cam 66 being absent, the pins 62 will project, so as to impale the freshly'cut ends of the webs and carry them around on cylinder 48, as shown in Fig. 9. The pairs of papers thus associated on the cylinder 49 will be released from the pins 70 and folded between the rolls 58 59 by blade 78 at the proper time, and in the manner already explained, and the operation will then be repeated. In Fig. 8 the cam 66 is shown as placed so as to co-operate with the pins 69. This, however, is immaterial, as the cam may be placed so as to cooperate with either they pins 69 or 70, the other set being rendered idle when sheets are to be associated. When the pins 62 are retracted to release the leading end of the sheets from cylinder 48, it is necessary that they should be prevented from protruding beyond the surface of the cylinder again until they have been carried sufficiently far from the surface of cylinder 49 to prevent their points from striking the paper upon that cylinder. In the construction shown in Figs.v 6 and 7 this is accomplished by a stationary cam, 83, within whichthe stud or roll 67 is forced by the cam 66, and inside of which it must travel, and which thus holds the pins 62 1n their retracted position until nearly a Whole revolution of the cylinder 48 has been completed. During that revolution of the cylinder 48, when the pins 62 are required to protrude,the stud or roll 67 passes outside the cam 83, it not having been acted upon at the commencement of the revolution by the cam 66. The cam 83 may be dispensed with and the same result accomplished by an elongation of the cam 66, as shown in Figs. 8, 9, and 10. If it is desired that the two products made at each revolution of the form-cylinders shall, instead of being duplicates, contain different matter, and thus combine to makea single product, the form-cylinders may be provided with appropriate plates or sets of plates. In that case each sheet of the two pairs which will be associated upon cylinder 49, in the manner ust explained, will constitute one-half of a single product,in stead of eachin itself forming a single or complete product. The number of plates carried upon the form-cylinders is of course immaterial, so long as they are divided into two equal sets, each occupying onehalf the circumferential extent of the cylinder. The columns of matter may also be arranged to extend around or lengthwise of the cylinder,

according to the style of product which it is desired to produce. It will, however, be found most desirable, it is thought, to use four plates upon each form-cylinder-two in length and two in circumference-and to arrange the columns of matter so that they will extend cireumferentially of the cylinder. When the plates are thus arranged, and the second pair of plates are duplicates of the first, the product will be four four-page papers at each revolution, such papers being longitudinally folded upon the line between thepages, and then either singly or in pairs folded transversely. When the plates are thus arranged and the matter upon the plates or sets of plates is different, the product will be two eight-page papers at each revolution, such papers being composed each of two four-page sheets, which are folded longitudinally between the pages and afterward associated as upon cylinder 49, and folded transversely together. The four-page sheets composing these products may be attached to each other by a line of paste placed contiguous to thelongitudinal fold-lines. Such line of paste can be readily applied by pastingdisks running in contact with cylinder 48. These disks should be made intermittent in their action, so that paste will not be applied to the surface of cylinder 48 at the times when there are no sheets upon its surface.

It has now been shown how the machine described can at option be made to produce either a four-page or an eight-page product, the pages being the same size in both cases,

or, in other words, a product containingmat-- ter equal to one-half the capacity of the formcylinders, or a product containing matter equal to the full capacity of said cylinders. If, however, it should be desired to construct a machine of this class capacitated to produce either a four-page, a six-page, an eight-page, or a twelve-page product, the pages being of the same size in all cases, it can readily be done by making the form and impression cylinders one half longer, which will capacitate the form-cylinders to carry two additional plates or pages of printing-surface each. When a four or an eight page paper is to be produced, the number and arrangement of the plates will be the same as already described, the plates covering only two-thirds the length of the cylinders, and the webs of course being of corresponding width. When, however, it is desired to produce a six-page paper, the two additional plates will be placed upon each form-cylinder, and webs of corresponding width will be used. As the perfected webs l2 and 13 advance toward the delivery mechanism and pass over their guide-rolls 37 42, slitters, as 84, (see Fig. 11,) are arranged to split the wels into two parts, one part being one-half the width of the other. As only the web 13 is shown in Fig. 1], its wider part is numbered and its narrower part to distinguish it in its further manipulation, it being understood that web 12 is similarly operated upon. Each narrow portion, as is carried under and around sets of parallel turnerbars, as 85 86, by which it is transferred laterally and associated with the wider portion, f},

so as to lie between the plies of the latter when it is longitudinally folded by the folder,

as 40, thus making the sections severed by the blade consist of six instead of four pages, which six-page product can be delivered either singly or in pairs, as already described in connection with the four-page product.

When it is desired to produce a twelvepage product, the additional plates upon the form-cylinders will contain different matter, and two six-page products will be associated and delivered in the same manner as two fourpage products are associated and delivered, as has already been described.

It is to be remarked that the narrow or onethird inset portions of the webs may be secured in place by a line of paste laid along the centers of the wider or two-thirds portions before the same are folded. Such a line of paste may be applied by any well-known device.

The turners 86, of which there will be two sets-one for each web-will be located between the guide-rolls 37 38 and 42 43, respectively, and should be made adjustable, as shown in Fig. 11, in order to secure the accurate registration of the printed matter upon the two portions of the webs. To provide for this adjustment of the turner-bars, their ends are supported in collars 88, which are swiv eled to the slotted brackets 87, secured to the frame of the machine by set-screws 89. The proper registration of the edges of the two portions of the webs is secured by adjusting the turners to the proper angle with relation to the webs, and their proper registration in the direction of their travel is effected by adjusting the bars to the proper distance from each other. The collars 88 are made capable of sliding along the bars 85 86, so as to permit this adjustment.

If it is desired to deliver as a product two or more sheets folded together, the primary fold being transverse to the run of the paper through the machine, the webs may be split longitudinally just before or during the passage over the longitudinal folders. This can be well accomplished by slitters, such as shown at X in Fig. 12. These slitters should be arranged so as to be thrown out of operative position when their use is not required. It will be readily seen that when the webs are thus split in passing the folders 40 45 these folders become merely web-associatin g devices, and cease to be longitudinal folding mechanisms.

In order to insure that the impressions made by the second form-cylinder shall register accurately with theimpressions made by the first, the webs, after receiving the first impression and before they reach the turners 20 41, pass over fixed guide-rolls, as 91, (see Fig. 2,) and under adjustable guide-rolls, as 90. By adj usting rolls up or down, the distance traveled by the webs between the cylinders can be varied so as to bring the impressions upon the opposite sides of the sheetinto proper register. The rolls 90 may be secured in their adjusted positions by a screw, or by any other suitable means. In the drawings the web 12 alone is shown as supplied with. this register-regulating device; but it is to be understood that the web 13 is also to be provided with similar devices. The distance traveled by the webs after leaving the second group of printing devices, and before reaching the longitudinal folders 40 45, may be varied so as to bring them into proper register with the severing devices 65 81 by the adjustment of the rolls 38 39 43 44.

In Figs. 3 and 12 there is shown a modified form of delivery mechanism, in which the longitudinal folders 40 45, instead of being located in the same plane and arranged so that both co-operate with the same pair of folding, cutting, and associating cylinders, are arranged one above the other, and provided with independent co-operating devices. The devices thus designated form two independent sets of delivery mechanisms, each of which delivers the product of one of the webs, the web 13 being operated upon by themechanisms of cylinders 48 49, and its product delivered between the rolls 58 59, and the web 12 by the mechanisms of cylinders 52 53, and its productdelivered bet-ween the rolls 60 61. The cylinders 52 53 are geared together, and are driven by gear 5 upon the shaft of form-cylinder 1 through the intermediate gear, 54. The cylinders 48 49 are also geared together, and are driven through intermediate 55, which engages with gears 56 57 upon the shafts of cylinders 52 and 49.

The folding-rolls 46 47, 50 51, 58 59, and 60 61 are or may be driven through intermediates connecting them with any appropriate one of the before-mentioned gears. These delivery mechanisms are exactly the same in their construction and operation as that already described, except that the rolls and cylinders are only of one-half the length.

It will be observed that the method herein described of printing the two webs and leading them to the delivery mechanism causes both webs to contain the same printed matter upon their upper surfaces, and that, therefore,

.when both webs are operated upon by the same delivery mechanism, as in Figs. 4 and 5, the products of both will be delivered in the same order, or with the same matter upon the outside. By the mechanisms shown in Figs. 3 and 12, however, the result will be difierent. The webs being folded in opposite directions, the matter which is on the inside of the product of one web will be on the outside of the product of the other.

It is to be remarked that it is not necessary that the two groups of printing mechanisms should be placed at right angles to each other. The angle may be either considerably more or less than a right angle, it being only necessary that the angle should be such that the webs can be conducted from one to the other by the use of a turner having a single turning edge or surface.

The impression-cylinders which act upon one or both of the webs should be made adjustable, so that they can be withdrawn from contact with the form-cylinders in case it should be desired to use the machine to print from one web only.

The gears 33 34, as will be observed, are secured to the shafts of the impression-cylinders 2 23; but it is to be remarked that it will usually be found preferable to place the gear 33 upon the shaft of the form-cylinder 1 and the gear 34 upon the shaft of the form cylinder 31.

A mechanism of the construction herein set forth possesses great advantages over those of the same general character heretofore used, in that both webs of paper are led from the same side of the machine, thus makingit easy for an operative to attend to both rolls at the same time. The product of both Webs is also delivered at the same or substantially the same point, and in close proximity to the rolls from which the webs are drawn, thus making it possible for the same operative to attend to both the feeding of the webs and the removing of the product. This novel arrangement of the various parts also renders the machine very much less cumbersome than those of an. equal capacity as heretofore constructed.

As will readily be seen, any ordinary form of delivery mechanism may be substituted for that here shown and used in connection with the printing mechanism herein described, and this delivery mechanism may be used in connection with other forms of printing mechanism.

Although the web-associating mechanism combined with web-severing and sheet-associating mechanism is herein shown, the same is not herein claimed, but is claimed in my application filed June 22, 1883, No. 98,940; neither are the duplicate delivery mechanisms shown in Figs. 3 and 12 herein claimed, as these mechanisms will form the subject-matter of afuture application for Letters Patent.

What I claim is- 1. The combination, with two printing mechanisms set at an angle to each other, of means for leading a web of paper to the first mechanism from the side adjacent to the second mechanism, a web-turncr arranged to turn and guide the web from one to the other, and means for leading the printed web from the second mechanism upon the side adjacent to the first mechanism, all substantially as described.

2. The combination, with two printing mechanisms, each consisting of one form-cylinder and a plurality of impression-cylinders set at an angle to each other, of means for leading a plurality of webs of paper to the first mechanism from the side adjacent to the second mechanism, a plurality of web-turners arranged to turn and guide the webs from the first to the second mechanism, and means for leading the printed webs from the second mechanism upon the side adjacent to the first mechanism, all substantially as described.

3.
