The drawings are made to scale, and the same letter 'of reference indicates the same part wherever it occurs in the figures.
Our invention relates to the combination, with a web-printing machine, of a folding mechanism to which the printed paper is antomatically delivered in a continuous web and in accurate register, and is then severed, folded, and packed by all rotary mechanism and by all positive movements, the paper being at all times completely under the positive control of the machinery by which it is carried to and through the folding mechanism.
Our invention consists in the mechanism, hereinafter particularly described, for. receiving, registering, presenting, holding, conducting, severing, creasing,nipping, releasing, carrying, guiding, regulating, folding, and packing paper printed in a web-machine and delivered to a folding-machine to receive in proper register, a predetermined number of folds, and be packed and delivered.
It further consists in details of construction, arrangement, and adjustment of the devices constituting the mechanism for the performance of any, or any combination, of the several functions hereinbefore referred to, all as hereinafter more fully set forth.
The construction and operation of our machine are fully illustrated in the accompanying twelve sheets of drawings, whereon A marks the frame of the machine, in which the operative parts are supported. The machine is to be attached to and work in harmony with a web-printing machine of any preferred construction. It receives the printed web of paper from the machine in proper register under the binder-roll B, which holds it to the severing-cylinder D and insures its passage between the severing-cylimlers C 1). These cylinders are adjusted to run in exact register with the printing-machine by a device hereinafter described. They are provided. with serrated cutters a I), which are shown in detail in Fig. 4. Their serrated cuttingedges are not continuous, but are provided at intervals with blank or open spaces or notches c c, where the cutters do not sever the sheet of paper from the web, but leave it attached by a narrow tag, (I. These cylinders have their circumferences equal in length to the length of the sheet to be cut off, or a multiple of that length, and they cut the sheet at the proper lines across its entire width except at the tags left by the spaces 0 0.
Of the cutters a b, the lower one, I), is flush with the surface of cylinder D, the upper one, a, projecting sufficiently at its ends to insure severance of the paper, and a little more at the center to produce a slightly shear cut and prevent the whole strain of the cut from being exerted at once. The condition of the paper on the out line, after passing between the cutters, is shown in Fig. 5, where d d mark the uncut portions or tags, by which the sheet is slightly held to the web, after being severed in the rest of its width, until it reaches the folding-cylinders.
The cutting-blades a I) may, if preferred, be placed directly on the folding-cylimlers E F, thus dispensing with the independent cuttingcylinders C D and the binding-rolls B B. In such case the grooves k in cylinders E F are made verry narrow, the tags or uncut portions of the paper being of corresponding width, and the separation of the sheet from the web is effected by a device hereinafter described.
The cylinders E F are shown on an enlarged scale in Figs. 6 and 7, Sheet 4. They are equal in circumference to the length of the sheet to be folded, or to some multiple of that length. The upper one, E, is provided with a row ofpins,j, upon which the leading end ofthe paper is impaled in order to be led between the rollers. It also has acreasing-blade, h, and a breaking-bar, i. The lower roller has a line of gripers, e, and a creasiug-groove,f, in the line of the fold, and a breaking-groove, g, on the opposite side.
The creasing-blade h of cylinder E works into the nippers c in the groove f, and the breaking-bar i into groove 9. The blade h forces the paper on the line of the first fold into the bite of the nippers e in the creasinggroove f. The blade h is cut away opposite the nippers 0, so that when the paper is forced into the groove f and into the bite of the nippers e the nippers may close upon the paper and hold it securely before the blade his withdrawn.
The pins j in the cylinder E are near the breaking-bar 1'. When the end of the sheet is impaled upon them it is carried up, supported by the surface of cylinder E, until it reaches the stationary inclined strippers H, (see Figs. 1, 2, 3,) whose forward ends enter grooves k in roller E. These strippers lift the forward half of the sheet from the roller E at the instant that the nippers e have seized it in the line for the first fold, and the further rotation of the roller F draws the forward part of the sheet down and oti'ot the cylinder E, and carries the creased edge or line of fold in between cylinder F and small roller G to complete the fold, the nipper 0 being opened to release the sheet by means of the lever j working on fulcrum 7c. and operating the wedge-shaped dog 12 which opens the nippers. The leverj is operated by means of the boss or cam m on the end of its longer-arm coming at the proper instantinto contact with the surface of roller G, as clearly shown in Fig. 7. The curved bars I m, entering grooves in roller G and cylinder F, respectively, withdraw the folded edge of the paper from the groove f and nippers e, and guide it out into position for receiving another fold.
In our first trialsof the machine the cylinder E was solid on its surface, and we found that as the sheet was drawn ofl from the surface of cylinder E, to be carried in the opposite direction, there was a tendency to create a vacuum between the sheet and the roller, which often caused the sheet to be drawn out of the nippers or torn. To remedy this the cylinder E is now perforated with numerous holes n, which allow free access of air to the under side of the sheet and completely relieve the tendency referred to. The sheet, positively held between cylinder F and roller G, is by them propelled forward between the rods 1 on until its folded edge reachesthe bite of the carrying-rollers I J K I J K, Figs. 1, 2, 3, the distance between their bite and that of the cylinder F and roller Gr being just half the length of the sheet to be folded. The sheetis released from the bite of F and G at the proper instant by means of the clearance-space 1), cut in the face of the roller F just in front of the breakin g-groove g.
Of the carrying-rollers just referred to the smaller ones, I J I J, (see Fig. 3,) are id-lers, operated by contact with the larger ones, K K. They are hung (see Fig. 1) in frames or brackets E adjustablysgsupported upon arms D to which they are pivoted at d Each frame or bracket has an arin, e the free end of which is adjusted by setrscrews f f passing through lugs on arm I). This adjustment regulates the relative position and pressure of the rollers 1 J upon the full arc of the roller K. The arm D pivoted at c to the crossframing, is pressed down by the spring k operation.
which is counteracted by the set-screw which supports the rollers I J in such a position that they do not enter the clearance-space q in the face of roller K. These adjustments provide for the nice regulationof the contact -and pressure between the small rollersand the carrier-rolls, with which they co-operate in carrying forward the sheet to the position to receive its second fold. r v
Thelower andlarger rollers, K K, of the first -set of carrying-rollers (see Figs. 2 and 3) have a greater circumference than the folding-cylinders E F, and, as they make one turn for each sheet folded, their surfaces move faster than the speed at which the sheet is traveling .when its folded edge enters the bite between these rollers and the binder-rolls which co-opcrate with them in its propulsion. The speed of the partially-severed and once-folded sheet is thereforesuddenl y increased over that of the web of paper the instant it enters the bite of thecarrying-rolls. At the same instant the breakin g bar and groove seize the front end of the succeeding sheet and impale it .upon the pins). The once-folded sheet in the bite of the carrying-rolls is thus torn from the sheet which follows it at the moment when the forsheet before the next sheet is presented to receive it.- r i The rollers K K have each a portion of the periphery cutaway toform a clearance-space, q, so that before the tail end of the full periphery reachesthc second smallbinder-roll. J,
the sheet has been'carried to its proper position to receive the second fold, and is released at the precise instant at whichit-is grasped by the blade 1" of shaft L and the griper of roller M in the second'iolding mechanism.
To ef fect this the carrying-rolls K K are provided with means'of accurate adjustment upon their shafts, so that they may be set with precision tothe exact time for releasing the sheet to the positive'control of the secon'dfoldiu g device. As the sheet enters thebite of these carryingarollers I J K, &c., on their full diameter, and as their circnmference,less the clearance-space q, is greater than half the length of the oncefolded sheet, the adjustment last above referred toldoes not affect the entrance of the sheet, but only its delivery to the subsequent The binder-rolls, as beforestated, are adjusted so as to bearrwith the proper degree of pressure upon the fullarcs of the carryingrolls, and yet are not permitted to drop into theclearance-space q', below the surface-line of the full arc. Hence the sheet is released the instant the last binder-roll passes off of the full arc of the lower carrier-rolls.
The once-folded sheet, in its progress to the mechanism which imparts the second" fold,
slideson the rods m, under the rods l, and is further supported by the roller L, whose upper surface is on a level with the upper surface of rods m, as seen in Fig. 8. The creaser-roll L does not turn in contact with rollers M or N. If it did, it is obvious that there would be no space for the introduction of the sheet endwise to the second folding-rollers to receive one or more folds at right angles to the preceding one.
The creasing-blade a" is attached to roller L in the manner shown in Figs. 8, 9, and 10, and during the greater part of the rotation of the roller L is entirely removed fromthe path of the sheet in its passage to the second folding mechanism. The blade is cut away at a number of points in its length to allow the projections on the nipper-bar s in roller M to gripe the edge of the sheet without grasping the blade.
The rollers Ii, M, and N are at right angles to cylinders E F and roller G, and give to the sheet two folds parallel to each other and at right angles to the first fold.
The second fold is made by blade 1' introducin g the sheet to the nippinggroove of roller M, and the'rotation of that rollerin the direction indicated by the arrow, carrying'the creased line of fold between rollers M and N and up to the stripper-rods c, which take the folded edge out of the gripe of bar s and carry it in between rods '1) and to. Just as this occurs the creasing-blade 1?, attached to r'oller M, (see Fig. 9,) introduces the sheet at theline proper for receiving the third fold into the griping device a of roller N, and the edge of the now thrice-folded sheet is carried by that nipper to the releasing-bars ac, where it is taken from the nipper and passed on between rods m w and between rollers N and P to the'bitc of carrying-rollers Q R. The roller Q, by reason of its circumference being longer than that of rollers N M, accelerates the speed of thesheet as it passes to the mechanism for giving the fourth fold. Rollers P and Q are, respectively, provided with clearance-spaces e f*, for the purpose of releasing the sheet at the proper instant in the manner already described. The second nipper-bar, 8, forms, when open, one side of the groove for making the crease, the projections t t of said bar being equal to the thickness of the blade 1", or a little more.
From thethird foldin g mechanism the thricefolded sheet, impelled by rollers Q R, passes between bars to and an, over rollers V T, and under creaser-blade y, attached to shaft S, Figs. 12
and 13. The'rollers T V are at right angles to the rollers-M N, and are located directly over the packing-box U.
The fourth foldis made in the same way as the second,'by the operation of the blade 3/ tucking the sheet into the nipping-groove'z of roller Tand carrying it down between rollers T V, when; if no more folds are required, it dropsinto the packing-box U, being guided into it by the switch-rods a being thrown back into the grooves 11 in roller T by means of lever X, attached to shaft Y, to which rods a are fixed. (See Figs. 12 and 14.)
The roller V has a longitudinal groove, 0, in it, Figs. 12 and 13, into which the top of the four-times-tolded sheet is carried by the hooks 01, attached to said roller. The distance from the bottom of trough U to the under side of roller Vis less than the length of the folded sheet, and the top of the sheet is received in groove 0 and carried past the roller V by the hooks d, thus insuring the top of the sheet being moved forward out of the way of the descent of the following sheet.
In the bottom of trough U are two disks,W W Figs. 2 and 12, running in slots 0 in barmony with the top roller, V, and having recesses f, into which the folded edge of the sheetenters when it falls from the folders, and is pushed forward into the trough by the shoulders g of the recesses. Thus the sheet is packed simultaneously at top and bottom by the joint action of the roller V at top and the disks W W at bottom, both having continuous rotary movement, and forming together a rotary packing device.
When it is desired to give the sheet of paper five folds the bars a. of the stripping device or switch, Figs. 12 and 14, are thrown into the grooves h of roller V by depressing lever X, and the four-times-folded sheet, instead of falling into trough U, is guided out horizontally between the rods 2" j to the fifth folding mechanism. The folding-rollers of this device are at right angles to those of the fourth, and operate to give the fifth fold in the same manner as those heretofore described. The sheet is carried over the roller 0 between rods i j by the carrier-rollers Z A, Fig. 21. The creascr-blade k introduces the sheet to the nipper-groove in roller 0, where it is seized by the nipper l and carried down between folding-rollers U and D, and received by the packing device in trough F. This device consists of a roller, D, having a groove and hooks similar to those in roller V, and the revolving disks E, similar to disks W W turning in slits in the bottom of trough F. It operates by continuous rotary movement to pack the sheets in trough F in the same manner as the packing device for the four-times-folded sheet hereinbefore described.
The folding-machine is driven by being geared to the printing-machine with which it is intended to operate. The winch, Figs. 1 and 2, indicates the point of application of the driving-power.
The gearing connecting the printing-machine with the folding-machine requires to be adjusted with the great-est accuracy, so that the printed web of paper may reach the folding mechanism in perfect register. In order to facilitate this, we have devised two methods of making the adjustment, which are illustrated in Figs. 27 and 28 and Figs. 29 and 30.
Fig. 27 is a face view of a compound gear, consisting of an annular rim, G, concentrically attached to and adjustable upon a central disk, H, fixed to the shaft 1 of cylinder 0 by a feather or other suitable means. The rim G is provided with three slots, two marked a and a third marked 1%, through which the clamping and adjusting devices work. Binding-screws z z are inserted through the slots a a A stud, u, attached to the face of disk H, projects through slot u and is held in any desired position by means of adjusting-screws m y, passing through lugs 'v 10, attached to the face of rim G. By loosening screws 2 and operating screws 3 m the desired adjustment of the toothed rim G relatively to shaft 1 can be made upon the central disk, H, and
the adjustment, when made, can be maintained.
by tightening the screws 2 z to clamp the disk and rim together.
Figs. 29 and 30 illustrate a device, substantially the same as the foregoing, with the studs u and the lugs v 'w omitted, they being replaced by simple slots 0 and binding-screws b and the adjusting movement between the movable toothed wheel J z and the central disk, K fixed to shaft L, being moved by hand, and held by bindingscrews b passing through slots 0 into the body of wheel J as clearly shown in the figures.
It sometimes happens that the folding-machine is stopped or jammed by accident. It is important that provision should be made for automatically preventing the stoppage of the folding mechanism from arresting the movement of the printing mechanism. This we accomplish by what we call a tripping device, which is shown in central section in Fig. 31 and in front elevation in Fig. 32, and which we will now describe.
P (see also Fig. 2) is an outer gear, fixed by a feather to shaft Q of cylinder E, and forming part of the train of gearing by which the folding mechanism is driven. It receives motion from the train of gearing from the printing-machine by reason of its connection with inner gear, N, on shaft Q, which is not fixed to that shaft, but is attached to gear P by the tripping device, which holds the two together as long as both printing-machine and folder are running, but disconnects them as soon as the folding mechanism stops. When such a stoppage occurs the gear N, driven by M, continues to rotate like a loose pulley on shaft Q without turning said shaft or the gear P This disengagement of N from P is due to the action of spring-latch S, whose head 0 is provided with a recess, g which engages with an inclined shoulder, 19', on the inside of the rim of the wheel N and holds that wheel to P until the latter stops, when the head 0 rides up on shoulder 19*, forces the latch S back till it is caught and held by spring-dog R, the inner end, h, of which enters recess g in latch S, and holds the latch-head 6 out of contact with shoulder 12 until dog R is retracted by hand. The latch S is impelled outward by the reaction of bow-spring f, whose tension is regulated by screws m m,
the second and third passing through lugs d on gear P The latch is held in its socket e by screw 1' entering groove 8 in the side of the latch.
To insure smoothness of running and compensate for lost motion or backlash, we employ the device shown in Figs. 33 and 34.
The gears T and VV running side by side on shaft V of cylinder D, both mesh into the gear G on the end ofthe shaft of cylinder 0. The gear T is keyed to the shaftV but the gear W is free to turn on that shaft, and is held in contact with gear T by collar m held on the end of the shaft by set-screw 3 A stud. o projecting from the inner face of gear W receives the reaction of the free end of a coiled spring, U, whose fixed end is attached by screw 10 to the nave of gear T. The effect of this construction is to keep the teeth of the gears T W at all times in positive contact with the teeth of the gear G, which drives them, the teeth of gear T bearing against one side of the teeth of G, and those of gear W bearing against the other side, as illustrated in Figs. 35 and 36.
Themovements of the machine are derived from the power which drives the prin ting-machine by suitable connections, the point of application of the power to the folder being at the end of the shaft of cylinder 0. (Indicated by the winch in Figs. 1 and 2.) On the other end of said shaft is a gear, G, which meshes into and drives gear W on the end of the shaft of cylinder 1), which, in turn, drives the binder-roll 13. Gear G also engages with reversing-gear M, which drives the train of gearing of the first set of folding-rolls and the binder-roll B. The last gear in this train is U on the end of shaft X, which carries the gears which impart motion to the second and subsequent folding mechanisms. meshes into gear H on the end of shaft W and thus drives the mechanism for the fifth fold. Gear Y on the same shaft meshes into gear Z on the shaft of the creaser-roll L of folding mechanisms. Gear W on the end of shaft X meshes into gear X on the end of shaft T to which the carrying-rolls K K are adjustably attached.
0n the rear end of roller L is gear A which meshes into gear B on the end of folding-roll M. B meshes into gear G on shaft of roller N, and gear (J into gear D on the shaft of carrying and releasing 1. On the end of shaft of roller N is gear E, which drives gear F on endof the shaft of carrying-rolls Q Q Rolls U", are narrow pulleys operating on the edge of roller M to open the nippers in the ordinary way. Rolls P I are carriers, and P I are releasing-rolls operating on the ends of roller N to open the nippers. Gear A on the 'inner end of shaft T drives the carrying mechanism for the fifth folding device. (Shown in detail in Figs. 17, 18, and 19.) It engages with a gear connected with the shaft of cam A, which operates the releasing-rollers Z Z by means of the friction-roller Z", attached tothe Gear G rolls P P P r Fig.
same frame, which rolls in contact with the face of cam A, and raises and lowers the rollers Z Z at the proper times. The cam is counteracted by a spring, around rod e which presses down the roller-frame. (See Fig. 18.) Gear G on shaft X Fig. 24, engages gear H on end of shaft W on the other end of which is gear 1 which operates gear K on the shaft of gear L, Fig. 2. Gear L drives gear Q on the end of shaft of the packing-disks W W in packing-trough U. It also drives gear M (see Fig. 15) on end of shaft of folding-roller T of the fourth folding mechanism. Gear M drives gear N on creasing-blade shaft S, also gear P on end of shaft of packing-roller V.
On shaft'VV is gear B". Fig. 20, which drives gear S on shaft of creaser B Fig. 21. It also drives gear V on shaft of gear D and gear T intermediate to gear U on end of recessed packing-disk E, Fig. .20.
The device for the vertical adjustment of folding-cylinder E is shown in Fig. 25. The journal of cylinder E turns in a box, u, held in a slot, i in the frame A, large enough to admit of they extreme adjustment which may be required.
The box a is inclined on its lower side, as shown, and below it is placed a wedge, c, operated by the screw 10, which carries it in' or out, as required, to raise or lower box a. A set-screw, a, entering above the box, serves to clamp it at the required position.
The device for eifecting the lateral adjustment of folder G is shown in vertical section in Fig. 26. The journal of folder G turns in box .2, placed in a slot, a in the frame. The screws b b govern and fix its position.
