SPECIFICATION forming part of Letters Patent No. 357,551, dated February 8, 1887.

Application tiled May 16, 1883. Serial No. 95,068.

To aZZ whom it may concern;

Be it known that I, LUTHER O. CROWELL, 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 WVeb Printing and Delivery Mechanisms, fully described and repre-- sented in the following specification and the accompanying drawings, forming a part of the same.

This invention belongs to that class of printing-machines which are adapted to print both sides of a continuously--rnoving web, sever the same into short lengths or sheets, and deliver said sheets as a folded product.

The invention relates more particularly to that class of these machines in which each form-cylinder is provided with a plurality of impression-0y]inders,so that duplicate printed webs can be simultaneously produced from the same set of forms or stereotype-plates.

It is the object of the invention to produce a mechanism of this character capacitated to perfect two webs of paper and deliver the printed product in eitherone of several forms, so as to meet the requirements of those newspaper printing establishments which issue large editions of papers of sizes which vary with different days of the week.

The invention, so far as it relates to the printing mechanism proper, consists principally in an arrangement of weh-turners, by

which the turning of the web between the im-.

pressions upon its opposite sides is avoided, and by which both webs, when two are being operated upon, are delivered from the printing apparatus running in the same direction and with the same matter upon their respect ive upper and lower surfaces.

The invention, so far as it relates to the delivery mechanism, consists principally in an arrangement of the cutting and folding devices by which sheets of various sizes can be produced and folded at pleasure, and by which a single cutting and folding mechanism can, when desired, be made to receive and dispose of both webs; and also in the combination, with two primary web-severing and sheet-folding mechanisms, of a single secondary or final sheet folding and delivery mechanism ar- (No model.)

ranged to receive and dispose of the product of both of said primary mechanisms.

The invention also embraces numerous details of construction both in the delivery and printing mechanisms, singly and in various combinations, as will be hereinafter fully eX- plained, and particularly pointed out.

In the accompanying drawings, Figures 1 and 2 are opposite side elevations of a mechanism embodying the present invention. Fig. 3is a longitudinal vertical section of the same. Fig. 4 is a plan view of the printing and primary delivery mechanisms. Fig. 5 is a horizontal section ofthe same, showing more particularly the tnrners for operating upon the the lower web. Fig. 6 is a transverse vertical section taken upon the linear of Fig. 1. Fig. 7 is a plan view of the secondary folding mechanism, the final delivery mechanism being omitted. Fig. 8 is a longitudinal vertical section of the same, taken upon the line y y of Figs. 7 and 9; and Fig. 9 is a transverse vertical section of both the primary and final delivery mechanisms.

The printing mechanism proper consists of two type or form cylinders, 100 101, each of which is provided with two cooperating impression-cylinders, 102 103 and 104. 105, and suitable inking mechanisms (indicated bythe rolls 107) for supplying ink to the forms, the Whole forming two printing mechanisms, one for each side of the webs, all of which parts are mounted in suitable bearings in an appropriate frame and receive motion through suitable gears, as 108, all in the usual manner. To the printing mechanism thus organized there are led two webs of paper, one from the roll 109,mounted upon a spindle located at the end of the machine, as seen in Fig. 4, and the other from the roll 110, mounted in like manner at the side of the machine, as also shown in said figure.

The Web from the roll 109, which for convenience is designated A, passes over leadingrolls 111 112, and thence between the formcylinder 101 and impression-cylinder 104 of the first printing mechanism, by which it is printed upon its under surface. It thence passes around the impression cylinder 104,

leading-rolls 113 114., which for a purpose that IOO will presently appear, are located from each other a distance somewhat greater than the width of the web, thence overleading-roll 115 to the second printing mechanism,where it passes between the form-cylinder 100 and the impression-cylinder 102 in such position, as will readily be seen by reference to Fig. 3. that its unprinted side is brought next to the formcylinder,so that when it passes from this mechanism it has been printed upon both its surfaces. From this point the printed web passes around leading-roll116,and thence around the webturner 117, (see Figs. 3 and 4,) by which it is turned so as to pass forward at right angles to its previous path of travel. It then passes outward laterally to the side of the machine and around a roll, 118, where it is split into three sections by the rotary cutters 119 120. The three sections of the web then pass to the web turners 121 122 123, located, as shown in Fig. 4, above the plane of the webturner 117, and above the web as it passes from the first to the second printing mechanism. The three sections are then led around these turncrs, so as to be turned again at right angles to their path of travel and also associated, if desired, as will be hereinafter explained, and thence pass under a guide-roll, 124, and over a guide-roll, 125, into the bite of the cutting and folding cylinders 126 127 of the primary delivery apparatus.

The second web, which for convenience is designated B, is led from the roll 110, mounted as shown in Fig. 4, and entering the side of the machine passes around the web-turner 128, (see Figs. 1, 3, and 5,) so as to be turned at right angles to its path of travel. It thence passes around the leading-roll 129, and between the form-cylinder 101 and impressioncylindcr 105 of the first printing mechanism, after which it is led around the leading-

rolls

130 and 131, and between the form-cylinder 100 and impression-cylinder 103 of the second printing mechanism, all as shown in Fig. 3.

The perfected web now passes beneath the roll 132, where it, like the web A, is split into three sections by the rotary cutters 133, (only one of which is shown,) corresponding to the cutters 119 120, before referred to. From this point the sections of the web pass either around turners 134 135 136 to be associated, as will hereinafter appear, or pass directly over roll 137 and into the bite of; the lower cutting and folding cylinders, 138 139, of the primary delivery apparatus.

From this it will be seen that all turning of the webs between the printing of their opposite sides is avoided, and also that all turn of the web B is avoided, except the single turn which it receives as it enters the machine. Even this turn of the web B may be avoided by mounting the roll 110 inside the frame of the machine and between the cylinders 103 105. The arrangement shown is preferable, however, because it renders the roll more accessible and lessens the trouble of placing a new roll in position when one is exhausted.

It will also be observed by following the course of the websAB, as has been pointed out, that as they enter their respective primary delivery mechanisms the side of each web which receivedthe last impression-tl 0.. that from the cylinder 100is uppermost. This enables the sheets severed from the two webs to be folded in the same direction and pass to the same final delivery mechanism.

The two pairs of cutting and folding cylinders 126 127 and 138 139 composing the primary delivery mechanism are exact duplicates of each other, consequently a description of one will suffice for both.

The cylinders 126 138 are each shown as of the same size as the. form-cylinders, and are provided with severing-blades 99 and with recesses 96 97 98, (see Fig. 9,) whereby the position of the blades 99 upon the cylinders can be changed, and whereby, also, the cylinders may be provided with a second severing-blade (not shown) when desirable, as will hereinafter appear.

The cylinders 127 139, which are here shown as of twice the size of the form-cylinders, are provided with four rotating folding-blades, 92 93 94 95, constructed in the usual manner, and which operate at the proper times to fold the sheets carried by said cylinders into the bite of the folding-rolls 90 91. These cylinders are also provided with four sets of sheet-holding pins, 86 87 88 89, which are mounted in removable carriers, so as to be placed in different positions upon said cylinders, for a purpose that will hereinafter appear, and are protruded and retracted so as to impale and release the sheets in the manner substantially as shown in United States Letters Patent No. 255,723. These cylinders are also, it will be observed, provided with additional recesses 84 85, for the reception of the pin-carriers, so that the pins can be placed to operate at different points upon the cylinders when desired.

The pincarriers are provided just in advance of the pins with cutting-grooves, with which the blade or blades upon the cylinders 126 138 co-operate to sever the web into sheets as it passes through the bite of said cylinders.

The cylinders constituting the primary delivery apparatus just described are geared together, so as to be driven in unison with each other, by gears 80 81 82 83, and receive motion from the printing mechanism through the train of intermediates 79. The folding-rolls 9O 91 are provided with tapes 77 78-, passing around said rolls, and pulleys 71 76, which, together with the stationary guide 72, form pathways for conducting the sheets folded from the cylinders 127 139 to a common exit between the fixed guides 73 74. The pulleys 70 71, forapurpose to be hereinafterexplained, are not placed in close biting contact, but at a short distance from each other, so that the sheets will not be held tightly between the tapes passing over them. These series of tapes and the pulleys over which they run are, or may be, positively driven in the usual manner, as by gears 68 69 connecting them together and to the gears 81 82, as shown in Figs. 1 and 2.

The secondary or final delivery mechanism, to which the sheets are delivered from between the guides 7 3 74,consists of three longitudinal folders, 64 65 66, and three cooperating folding-cylinders,61 62 63,which receivethe sheets after they have been operated upon by the longitudinal folders and deliver and associate them upon the traveling apron or traveling tapes 60, by which they are conducted to any suitable point at the side of the machine, to be piled by a fiy or other suitable mechanism.

The folders 64 65 66 each consists of an internal guide, external turners, and suitable cooperating conducting tapes. The internal guide and external turners of these folders may be of the construction shown in United States Letters Patent No. 233,997 but will preferably be of that shown and described in my application for Letters Patent filed December 10, 1881, Serial No. 47,528. Reference is therefore made to said patent and application for a detailed description of the same. The system of taping, however, by which the sheets are conducted over and around these folders and the co-operating folding-cylinders will be explained. As, however, these folders and their co-operating devices are exact duplicates of each other, a description of one will be considered as applying to all.

The first series of tapes, 59, (see Figs. 7, 8, and 9,) pass around pulleys 58 above pulleys 57, thence downward at an angle across the face of the folders, returning around pulleys 56. Cooperating with this series of tapes is a second series, 54, a portion of which pass around pulleys 53 57,- the remainder passing around pulleys 53 57 and other pulleys (not shown) located near the apex of the folders, as best shown in Figs 6 and 9. These two series of tapes thus form a pathway in which the sheets are conducted from between the guides 73 74 onto the longitudinal folders, the first series,59,conducting the sheets from that point across the faces of the folders. When the sheets have advanced so far along the faces of the folders that their forward corners begin to project beyond the inclined edges of said folders, said corners will be caught and carried downward by the tapes 51, which, passing over pulleys 52, follow downward along the inclined sides of the folders, pass around one of a series of pulleys, 50, which form the external turners of the folders, and return around pulleys 49. As the longitudinally-folded sheets pass from between the series of pulleys 50, forming the external turners, they will be conducted onto the foldingcylinders 61 62 63 by their respective series of tapes 47 48. The first of these series, 47, pass between the series of pulleys 50, thence downward and partially aroundthe folding cylinders and between folding-rolls 45 46, returning, respectively, around tightening-pulleys 44 49 and 43 and 49. The series of tapes 48, which oo-operate with the series 47 to con- Figs. 6 and 8.

duct the sheets to the folding-cylinders, pass between pulleys 50, around the folding-cylinders, and return, respectively, around tightening-pulleys 44 49 and 43 and 49, located upon the opposite side of the folder.

It will be observed that the pulleys 43 are placed in such position that two of the tapes 47 and 48, run for some distance along the inclined sides of the folders before passing between the external turners. This arrangement is not essential, yet it is deemed advantageous in that it tends to confine the sheets closely to the surface of the folders and prevent all liability of wrinkling or displacement. It will also be observed that the pulleys 44 49, over or in contact with which all the tapes of the series 47 48 pass, instead of being mounted upon shafts, are fixed to the ends of arms 42, (see Fig. 7,) mounted upon shafts 41, from which it results that each pulley can be moved independently of the others, so that each tape of a series can be tightened or loosened without disturbing any of the others.

- The foldingcylinders 61 62 63, which are in diameter somewhat greater than the form-cylinders, are each provided with two rotating folding blades, 40, located at opposite points upon the cylinders and operated in the usual manner to fold the sheets from said cylinders between the folding-rolls 45 46. The sheets, after passing the rolls 45 46,pass between fixed guides 39, and are delivered'onto the slowmoving tapes or apron 60, to be conducted to the side of the machine and delivered, as before stated.

The various moving parts of the final delivery apparatus just described are positively driven from the gear 80 of the primary deliv e'ry mechanism through intermediates 38 37 36 and shaft 35, as shown in Fig. 5, which shaft is also provided with a gear, 34, which engages with a gear, 33, upon the shaft 32 of the folding-cylinder 63, motion being communicated from this cylinder to the other folding-cylinders and to the external turners, 50, and to the pulleys 53 58,which drive the tapes 54 59,through gears 31, intermediates 30, bevelgears. 29, and shaft 28, as clearly shown in The fblding-rolls 45.46 are driven by gearing connecting them with the folding-cylinders in the usual manner, and the apron or tapes is or are driven by the belt 27, passing over pulleys 25 26 upon the shaft of one of the folding-rolls and the shaft of one of the rolls which drives said apron or tapes, as shown in Fig. 6.

It will be observed that the gears connecting the primary and final delivery mechanisms are of such size that the folding-cylinders of said final mechanism will make turn for turn with the cutting-cylinders 126 138 and with the printing-cylinders, from which it follows that as the folding cylinders 61 62 63 are slightly larger than said cutting-cylinders and the printing-cylinders, their speed, as well as the speed of the other parts of the final delivery apparatus which are driven from them,

will be slightly greater than that of the primary delivery mechanism, and that as a consequence the sheets in passing from the primary to the final delivery mechanism will be accelerated slightly, so as to be separated short distances from each other.

The printing and delivery mechanism which hasjust been described can be operated to pro duce and deliver either of the following products: A full sheet folded once longitudinally and twice transversely, two full sheets associated and folded once longitudinally and twice transversely, three full sheets associated and folded once longitudinally and twice transversely, or a halfsheet folded once longitudinally and once transversely. 'It is to be u nderstood that by folded longitudinally is meant folded in the direction of the travel through the machine.

\Vhen it is desired to use the full capacity of the machine in producing full sheets, as specified, the parts of the delivery mechanism will be adjusted as follows: The cutting-blades 99 will be placed in the recesses 96 of the cutting-cylinders, as shown in Figs. 3 and 9, and the pins 86 S9 of the cylinders 127 139 will be made inoperative and caused to remain rctraeted within theperipheries of the eyli nders. The folding-blades 93 95 will also be made inoperative by the removal of their drivinggears, 01 in any other convenient manner. This will leave two folding-blades, 92 94, and two sets of sheet-holding pins, 87 SS, operative upon each cylinder, and will cause the blade 99 to sever a sheet from the web at each halfrevolution of the cylinders 127 139, or at each complete revolution of the printing-cylinders. Two full width webs of paper will be used. The web B from the roll 110 will pass through the printing mechanismin themanner already described, and after being split into three sections by the slitters 82 will enter the bite of the cutting and folding cylinders 138139. The web A from the roll 109 will pass through printing and slitting mechanisms in the manner already described, after which all of the sections will be led around the turner 122, by which they will be turned at right angles to their path of travel, after which they will be led forward into the bite of the cylinders 126 127, as already set forth. As the leading ends of the sections of the web A enter the bite of these cylinders they will be impaled by the pins 87 and carried around upon the cylinder 127 until said cylinder has completed one-half a revolution, at which time the folding-blade 94, coming into operative position, will fold the sheets lying side by side upon this cylinder into the bite of rolls 90 91. Simultaneously with this folding of the sheets the pins 87 will be retracted so as to release their leading ends, and at the same time the blade 99 will come into operative position to sever the sheets thus folded from the sections of the web, the freshly-cut ends being at the same time impaled by the pins 88 just in the rear of the blade 99. The freshlycut ends thus held by the pins 88 will be carried forward in like manner upon the cylinder, and at the proper time will be folded into the bite of the rolls 9O 91 by the blade 92. It will readily be understood that in making this fold the sheets are reduced one-half in length in the direction of their travel, so that after they pass forward between the tapes 77 78 and the guides 73 74 they are separated from each other by spaces equal to their folded length. The sections of the web B which pass between cylinders 138 139 will be operated upon by the devices carried by said cylinders, so as to be impaled, folded, and severed in the same manner.

The operations of the two sets of this primary delivery mechanism will be so timed with relation to each other that the folded sheets emerging from between the lower set of tapes 77 78 will pass between rolls 7O 71, so as to just occupy the spaces between the sheets passing between said rolls from the upper set of tapes 77 78, from which it will be seen that the folded sheets delivered from the two cylinders 127 139 are caused to pass alternately between the guides 73 74, so as to be presented to the final delivery mechanism in an uninterrupted stream. This bringing into line the folded products of the two webs by properly timing the primary delivery mechanism makes it possible, as has before been stated, to deliver all of the sheets to and have them operated upon by a single final delivery mechanism. The sheets, now once folded transversely, pass forward between tapes 59 54 onto the three longitudinal folders 64 66, over which they are conducted by the system of tapes described, so as to pass between the external turners, 50, where they receive their second fold, which, it will be observed, is at right angles to the first fold and longitudinally of the sheets with relation to their direetion of travel. Alter receiving this longitudinal fold the sheets from the three folders pass between the tapes 47 48 onto the foldingcylinders 61 62 63. The sheets being new of such a length as to occupy only one-half or less of the circumference of these cylinders, each cylinder is enabled at each revolution to receive and fold two sheets between the foldingrolls 45 46, which, it will be observed, it is necessary for each cylinder to accomplish, since it must dispose of the product of the two primary folding mechanisms operated at the same speed. From the folding-rolls 45 46 the now completed product, having one longitudinal and two transverse folds, passes between guides 39 onto the moving carrier 60.

The movements of the carrier will be so timed that each sheet received from the cylinder 63 will arrive in position to have the next succeeding sheet delivered from the cylinder 62 imposed directly upon it, and that the two sheets thus associated together will arrive beneath the guides leading from cylinder 61 in time to have the next succeeding sheet delivered from that cylinder imposed ICC upon them, whereby as the sheets emerge from the side of the machine they are associated in groups of three each, which makes it possible for them to be received and operated upon by a fly or other ordinary piling mechanism operated at a comparatively-slow speed. From this it will be seen that at each revolution of the form-cylinders the machine, when thus arranged, produces and delivers six full sheets.

If it should be desired to deliver the same product, using only a single web of paper, the parts will be arranged and operated in the manner just described, except that one pair of impression-cylinders will be removed out of printing-contact with the form-cylinders. In such case only one pair of the primary cutting and folding cylinders will be used, and consequently the other pair may be thrown out of operation; and in this case also the final delivery mechanism may be run at one-half speed. For this purpose the gear 34 is mounted upon a sleeve, 23, which also carries a second gear, 24, of one-half the size of the former, said sleeve being splined to the shaft, so as to be capable of endwise movement, and provided with an operating-handle, 22, by which it can be shifted, all as shown in Fig. 5,

When it is desired to cause the final delivery mechanism to operate at one'half its usual speed the sleeve 23will be shifted, so as to throw gear 34 out of engagement with gear 33 and bring gear 24 into engagement with gear 31, the relative sizes of these gears being such as to reduce the speed of the final folding-cylinders and other parts of the final delivery apparatus one-half.

WVhen it is desired to produce a product consisting of two full sheets associated and folded, as described, webs of a width equal to two-thirds the length of the printing-cylinders will be used, and the web A, after being split into two sections by the cutter 119 or 120, will have its sections associated one upon the other by passing them respectively around the

bars

121 ,122 or 122123, so that the two will pass forward together to the folding-cylinders. The web B, after being printed, will be likewise slit into two sections by one of the cutters 133,

and its sections will be associated one upon the other by passing one of them around the bars 136 135 or 135 134, so that both will pass forward together to the folding'cylinders. The sections of the web B may be so associated that by being led upward they will pass between the cylinders 126 127 by the side of the associated sections of the web A, or when so associated they may be led directly to the cylinders 138 139. In the first ease the cylinders 138 139 may be rendered inoperative, and in either case the final delivery mechanism may be made to run at one-half speed; or, instead of pursuing either of these plans, the sections of the two webs may be so associated that those of the web B will, as they pass to the cylinders 138139, lie directly beneath those of the web A as the latter pass to the cylinders 126 127, so that the sheets severed from both webs will pass over the same longitudinal folder and to the same final folding-cylinder. The operation of the folding and cutting mechanisms will in this case be the same as already described, except that the various operations will be performed upon a two-ply instead of a single web.

Of course it will be seen that in this case, as in the case of single full sheets, the machine can be made to operate upon one instead of two webs, when desired. It will also be seen that webs of full instead of two-thirds width may be used, the extra section of each web being delivered in the form of single full sheets to form what are known as supplements.

When it is desired to produce aproduct consisting of three full sheets associated together and folded, as described, full-width webs will be used.

The web A, after being slit, will have its sections associated by passing them, respectively, around the

bars

121, 122, and 123, and

the web B, after being slit, will have its sections associated by passing two of them around the bars 135 134 and 136 134:, respectively, so that the three sections of each web will pass forward to the primary delivery mechanism associated together. In this case the association of the sections of the two websis such that they will pass side by side to the delivery mechanism. The associated sections of one of the webs may pass to the upper pair of the primary cutting and folding cylinders and the other to the lower pair of said cylinders, but it will be preferable to conduct the sections of both webs to the same pair of cylinders. In this case the sheets severed from each web will pass to different longitudinal folders and final folding-cylinders. Consequently, when delivering this product, it will always be advisable to have the sleeve 23 shifted, so that the gear 24: will engage with the gear 31, as, of course, it is desirable to run the final delivery apparatus at as slow a speed as possible.

If it is desired in any case to unite the several sheets forming the product, it can be done by ordinary pasting mechanism located in any convenient position to apply lines of paste to the webs or the sections of the webs at the proper points.

When it is desired to produce and deliver a product consisting of half-sheets folded, as deleys of one or more of the tapes of the series 48 will be lowered, so as to permit; said tapes to pass between the pulleys 45 46 and around the pulleys 46, so as to guide the sheets from between the tapes 47 48 into the bite of the rolls 45 46. This arrangement of tapes for guiding the sheets between the pulleys 45 46 is not herein claimed, however, but will be claimed in a future application for Letters Patent. In this case, as before stated, the sheets, instead of receiving two transverse folds, will receive only one-that made by the blades upon the cylinders 127 139. The final delivery apparatus will in this case be run at full speed.

The webs, after being perfected and slit into three sections each, as already described, will not be associated, but will pass directly to the primary delivery mechanism. The four sets of pins being in position to be operative, and the cylinders 126 138 each carrying two cutting-blades, it will readily be seen that the sections of the webs will be severed into half instead of whole sheets, and all four of the folding-blades being in operation such halfsheets will be regularly folded between the rolls 9O 91. The timing of the parts will in this case be the same as already described in connection with single full sheets, so that the once-folded half-sheets, as they emerge from between the upper and lower series of the tapes 77 78, will alternate with each other and pass forward between guides 73 7t and onto the longitudinal folders in an uninterrupted succession. In passing over the longitudinal folders these sheets will receive the second fold at right angles to that already made. After passing between the pulleys 50 they will be carried by the tapes t7 4Spartially around the cylinders (31 62 63, from which they will be directed between the guides 39 onto the moving tapes, in the same manner as in other forms of the product. The tapes will in this case, as in the ease of the other products, move at such a speed that the sheets will be associated in groups of three, so as to be taken by a fly or other mechanism having the same movement as in the former case.

If it should be desired to divide the product of the apparatus into separate lots, or to direct portions ofit to different laying mechanisms, it can be done by removing the tapes 60 and providing each of the cylinders 61 62 63 with an independent piling mechanism, or by shifting the guides 3.) of any one or more of said cylinders into such position as to direct the sheets from such cylinder or cylinders into a separate pathway leading to an independent piling mechanism.

If it should be desired to impart but a single fold to the sheets, the final folding mechanism may be omitted and the sheets delivered from the pulleys 71 directly to a fly or other piling mechanism. In this case the cylinders 127 and 139, instead of being timed to fold alternately, may be timed to fold simultaneously,

so that the sheets from both cylinders will be associated as they pass between the pulleys 70 71, and pass together to the piling mechanism.

The proper register of the impressions upon the opposite sides of the webs is secured by means of the rolls 113 114 and 180 131, which are made adjustable, so as to regulate the travel of the webs between the printing of their opposite sides; and the proper register ofthe sections with relation to the cutting and folding mechanism and with relation to each other when associatedmay be effected by the ad j ustment ofthe turning-bars and by the adjustable rolls 20, around which two of the sections may be led, when necessary.

If it should not be desired to give great capacity to the printing mechanism, the printingeylinders may, of course, be made only ofsufiicientlength to operate upon a single-width web, in which case the product will be limited to a full or a half sheet.

The combination, with a plurality of folding mechanisms, of a moving carrier, as 60, arranged to receive the sheets delivered from said mechanisms, associate the same into lots, and deliver said lots to a flyor piling mechanis1n,is notherein claimed,as the sameis claimed in my application filed June 22, 1883, No.
