DELIVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 383,800, dated May 29, 1888.

Application tiled November 10, 1887. Serial N o. 254.765. (No model.)

To all whom it may concern: i

Be it known that I, LUTHER C. OROWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State-of New York, have invented certain new and useful Improvements in Delivery Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the ro same.

This invention relates to a delivery mechanism which is especially designed to be used in connection with a web -printing mechanism which prints upon a plurality of webs,or upon a wide web which is split longitudinally into a plurality of webs after being printed, it being the object of the invention to produce a simplified form of delivery apparatus by which the plurality of webs thus printed can be delivered in products of various sizes or volumes-- as, for example, in products composed of one, two, or four sheets.

To this end the invention consists, principally, in a novel arrangement of a plurality of longitudinal folders with relation to the other parts of the mechanism, whereby the full capacity of the printing mechanism can be utilized in producing singlesheet products without duplicating the entire deliverymech- 3o anism.

The invention also embraces certain novel features in relation to the cutting, transverse folding, and sheet-associating mechanism.

'As a full understanding of the invention can best be given by an illustration and a detailed descriptionof an organized delivery mechan- `ism embodying the same, al1 preliminary description will be omitted and a full description given, reference being had to the accompany- Figure l is a sectional elevation of a delivery mechanism embodying the invention, showing also a diagram of the principal parts of the printing mechanism. In this, as also in the other views of the drawings, the gearing and also many of the minor details of the delivery mechanism are omitted, as such parts can readily be supplied by any ordinary skillful mechanic, and if shown would only tend 5o to create confusion in the drawings. Fig. 2 is a plan view of the same. Fig. 3 is a sectional elevation looking from the right of Figs. l and 2. Fig. 4 is a similar view showing the parts in a different position. Fig. 5 is an enlarged nend View of the cutting, folding, and associating cylinders. Fig. 6 is a plan View of the same. Figs. 7, 8, 9, 10, and 11 illustratedetails,which will be hereinafter referred to, Fig. 9 being a section on the line 9 of Fig. 8; and Figs. 12 to .20-are views showing the differentsized products.

Referring to said drawings, it is to be understood that the printing mechanism therein shown is of substantially the ordinary form, i consisting of form cylinders A, impressioncylinders B, and inking mechanisms represented by the rolls and cylinders C, all of which are arranged in the usual manner, and are of sufficient length to capacitate the machine to operate upon a double-width web. The web D is led from a roll, and after passing between the first form and impression cylinders to be printed on one side is led between the second form and impression cylinders to be printed upon its other side, and passes thence over a roll, 50, where it is operated upon by a slitter, 49, and split into two longitudinal sections or narrow webs, d,which narrow webs are then led to the delivery mechanism.

The delivery mechanism as herein illustrated consists of a web-associating mechanism ofthe ordinary form, consisting of two web-turners, 47, two longitudinal folders, 5l 52, a transverse cutting, folding, and associating mechanism composed of two cylinders, 45 46, and asheetpiling mechanism composed of a rotary S- shaped iiy,59, and a series of slowly-moving tapes or belts, 54. The webturners 47, composing the web-associating mechanism, are arranged obliquely across the paths of the webs d, so that as the two webs are led around their respective turners they are brought one directly beneath the other. i The web-turners are adjustable, so that they can be shifted to accommodate webs which vary in width. After being thus superimposed, the two webs are led around rolls 2l 22, and pass thence over rolls 38, located at the bases of the longitudinal folders 51 52, and over the folders. The roll 2l is adjustable, so as to vary the travel of one of the webs to secure the proper register. These longitudinal folders as herein shown are of substantially the form and construction illustrated and described in the United States Letters Patent No. 331,280, heretofore granted to me. They may, however, be ofany other suitable form. These folders are arranged one a short distance in advance of the other and in line, so that the same external tu rners, 20,co-'operate with both folders, and so that both webs 'pass between the same fold-laying rolls, 23, partially inset one within the other. The purpose of this will be made clear when the operation of the apparatus is explained. The rear folder, 52, is supported in substantially thev usual manner, its base being supported by arms 37, loosely mounted on bushings of the shaft of the roll 38 at the base of the folder and its point by an adjustable rod, 39, extending from the frame of the machine. The forward folder, 51, is supported only at its base, and in order to give it the necessary rigidity the arms 37, which extend' from bushings of the shaft of the roll 38 at its base, are connected by a wide bar, 40, which rests upon cleats 41, and to which the base of the folder is secured. This permits the folder 51 to be swung up to a substantially horizontal position when desired. For the purpose of adjustment the bar 40 is provided with adj usting-screws,43,which bear uponthe cleats41.

From the fold-laying rolls 23 the two longitudinally-folded and partially-inset webs pass to the transverse cutting, folding, and associating cylinders 45 46. The cylinder 46 is of a circumference equal to the length of two of the sheets to be produced, and is provided at opposite points with two cutting-grooves, 2, and at the proper points between these grooves with a pair of rotary folding-blades, 19, which latter operate in the usual manner to fold the sheets from the cylinder into the bite of a pair of folding-rolls, 18. The cylinder 46 is provided with two sets of sheet-holding pins, 3,

which are located just in the rear of the cuttinggrooves 2. These pinspass through openings in the periphery of the cylinder and are pivoted upon the ends of arms 4, extending from rock-shafts 16," journaled in the head of the cylinder'and provided with arms 17,having studs or bowls, which engage with a-stationary cam. 24, in such manner as to retract the pins within the periphery of cylinder at the proper times. The pins are normally held in their protruded position by means of springs 25, which act upon rods 26, which are pivoted to arms Aextending from the rock-shafts 16 and pass through guides 1.5 upon the cylinder-head. In order to hold one set of the pins permanently in their retracted position, which will sometimes be necessary, as will be hereinafter explained, the rod 26 of that set of pins is provided at its end with a latch, 14, (see Figs. l0 and 11,) which is pivoted in a slot Vin the end of the rod, and is so formed that when the spring 25 is compressed slightly beyond the position to which it is compressed by the cam 24 the latch will ldrop and engage with the guide 15, as shown by dotted lines in Fig. 10, and thus hold the pins permanently in their retractedposition. When, however, the pins are retracted by the action of the cam 24, the shoulder of the latch 14 is not quite withdrawn from the guide 15, and consequently the latch does not engage withthe guide.

The cylinder 45 is preferably of a circumference slightly less than one-half the circum ference ofthe cylinder 46 and is provided with a cutting-blade, 5, which is arranged to cooperate with the grooves 2 in such manner as to sever a sheet from each web at each revolution lof the cylinder 45, or at each half-revolution of the cy1inder46. This cutting-blade is of an ordinary for m,and requires no specific description. The cylinder 45 is provided with one set of impaling-pins, 6, which are located just in the rear of the blade 5. The pins 6, like the pins 3, pass through openings in the periphery of the cylinder, vand are pivoted to arms 7, extending from a rock-shaft, 12, which is journaled in the cylinder-heads,and is provided with an arm, 13, to which is pivoted a camlever, 27, the opposite end of which is fulcrumed upon the head of the cylinder, as shown at 28,'the pivoted connection with the arm 13 being such as to allow a slight amount of play. The cylinder 46 is provided upon one end with a cam projection, 29, which is so arranged that at each alternate revolution of the cylinder 45 it will engage with the projection'oi' the cam-lever 27, and thereby rock the shaft 12, so as to retract the pins 6 within the periphery of the cylinder. Theparts are so positioned that this retractionof the pins 6 will take place at or immediately after the time when the cutting-blade 5 co-operates with one of the grooves. 2 to sever the sheets from the webs. To reduce the wear of the cam projection 29 and the` cam-lever 27, the latter may be f provided with ank anti-friction rod, 42. The pins 6 are normally held .in their protruded position by means of avspring, 30, arranged to act upon a shaft, 3.1, having a segment, 32, which engages with acorresponding segment, 33, upon theshaft 12. To limit the extent to which the pins 6 will be protruded by the spring 30, the cam-lever 27 is provided upon its inner face with a recess, 11, into which projects a sliding bolt, 34, which rests in a recess f in the head of the cylinder 45. (See Figs. 7, 8, and 9.) The recess 11 isof such length asto arrest the lever 27 at the proper point to prevent the pins.from being protruded too far.

It will sometimes be necessary, as will be hereinafter explained, to maintain the pins 6 deliverthe full capacity of the printing mechanjsm either in theform of'one, two, or four sheet products folded once longitudinally and once transversely, or three-fourths the full capacity ofthe printing mechanism in products consisting of one full and one half sheet or two full and two half sheets folded to the same dimensions.

The operation of the mechanism in delivering these differentproducts is as follows: Ifit is desired to utilize the full capacity of the printing mechanism in producing four-page papers-that is to say, papers consisting of one fnll sheet--the folders 51 52 will both be used, the pins 6 will be rendered inoperative'by being retracted, and both sets of the pins 3 will be rendered operative. A full-width web will be used, which, after being printed, will be split, and the two narrow webs thus formed will be led around the tur-ners 47 and to the longitudinal folders, one webV passing -over each. folder, as indicatedin Figs. 2and 3. The distance-which the folder 51 is placed in ad vance of the folder 52 is such that the sides of the web passing over the folder 51 will overlap the sides ofthe web passing` over the other folder, as indicated at Fig. 3, so that as the two webs pass between the fold-laying` rolls 23 they will be partially, but not wholly, inset one within the other, as indicated at Fig. 20. In

= this condition the twowebs will pass into the bite of the cylinders 45 46, where the leading ends of the web will be taken by one of the sets ofpins 3 and carried' around upon the cylinder 46 until the foldingblade 19 arrives in the proper position `to fold' the sheets be tween the rolls 18,'when the pins will be retracted and the blade operated to fold the sheetsbetween the rolls, and immediately after this the blade 5, co-operating with the groove 2, will sever the sheets, leaving the freshlysevered ends of the web impaled upon the other set of pins 3, and the operation will be repeated. After passing the rolls 18 the sheets emerge in the condition shown in Fig. 12and will then pass into the control of the Vtapes 1 and be conveyedto the iiy 53, and by it piled upon The s1owly-n1oving tapes54, in the usual manner. The delivery may also be provided with a Acounting mechanism, 35, 'similar to that described in my prior Letters Patent, No. 331,282, Vwhich ,will operate to divide thesheets into lots of any desired number. From this it will be seen that the two singlesheet .or four-page products are delivered partially, but not wholly, inset one M-'ithin the other. If the two sheets or products were fully inset, then the operation of separating them, which of course is necessary, would be slow and difficult; but the sheets not being fully inset it becomes possible to separate them readily and with great rapidity by sim ply grasping the folded edges of one sheet and the free edges of another and drawing them apart. To do this packs of twenty or more sheets may be taken at the same time. This peculiar' inanner, however, of delivering the sheets, when single sheet products are being produced,

greatly simplifies the delivery mechanism, as by this means the transverse cutting, folding, and associating mechanism, by being very slightly increased in length,l is enabled to operate upon both webs, and thus an extra mechanism of this character is avoided..

If it is desired to utilize the full capacity of the printingmachine in producing two-sheet or eight-page products, the operation may be exactly the same, except that the two webs d will be associated and pass over one of thelongitudinal folders, as shown in Fig. 4. The two associated webs may be led over either of the longitudinal folders. As hereshown,they are led over the rearone of the folders, and in such case the front folder will preferably be so supported, as in the case shown, as to be capable of being swung up to the horizontal position indicated in Fig. 4, in which position it may be fastened by a hook, 36, or other suitable means. When producing this product, the two webs will be fully inset as they pass between the fold-laying rolls 23, as shownin Fig.` 13, andthe product will be delivered in the form shown in Fig. 14.

When it is desired to utilize the full capacity 'of the printingmachine in producing products consisting of four sheets or sixteen-page papers, the adjustment and operation will be the same as in producing the two-sheet pro-` duct just described, except that the pins 6 of the cylinder 45 will be rendered operative, and the set of pins upon the cylinder 46, opposite to the cam projection 29, will be render ed inoperative. As the leading ends of the associated and longitudinally-folded webs ar- `rive at the bite of thecylinders 45 46, they will in this case be taken by the pins 6 and carried around the cylinder 45 until that cylinder has completed a revolution,when thewebs will be severed by the blade 5, and at the same time the pins 6 will be retracted. Just before this takes place the pins 3 of the cylinder 46 will take the webs, and also the forward ends of the two sheets, upon the cylinder'45 and carry the forward ends of both of the webs and sheets forward upon the cylinder 46, so that the sheet will become associated with the leading ends of the webs. When the cylinder 46 has made a half-revolution from this point,the blade 5 will again sever the webs, the pins 6 taking Vthe freshly-severed ends, and the blade 19V will be operated to fold them transversely between the rolls 18, the'same as before.` The product thus produced will consist of two pairs of longitudinally-folded sheets associated and folded transversely together, as indicated in Fig. 15.

To produce products consisting of one full sheet and one half'sheet the adjustment and operation will be the same as in producing products consisting of two full sheets, except that the web D will be ofthree-fourths width so that one of the webs d will be of halfwidth. The webs d will then be associated and folded as indicated in Fig.` 16.

To produce products of two full sheets and IOO IZO

two half-sheets, such as shown in Fig. 17, the adjustment and operation will be the same as in the case of the four-sheet product, except that the web D will be of three-fourths width. Products consisting of two full sheets may also be produced by using a web, D, of half-width and operating the cylinders 45 46, the same as in producing the four sheet product, as shown in Fig. 18, or by using a web, D, of full width, leading one of the webs d over. each longitudinal folder and operating the cylinders 4546 in the same manner, as shown in Fig. 19.

Still other variations in the size and form of the products produced and delivered may be obtained by increasing the circumferential capacity of the printing cylinders and by arranging the mechanism for operating the pins and folding-blades of the cylinders 45 46 so that said cylinders will operate to associate three or more sheets or pairs of sheets. This can readily be done by any ordinarily skillful mechanic if any such range of capacity should be desired in any particular case. Still greater capacity and range in the size of the products may be obtained by usinga supplement web in addition to the main web, and such supplement web can be supplied from any supplement-printing mechanism located atthe side of the delivery orin any other convenient position. In such case the supple-V ment web will be led into the delivery, so as to be associated with the webs d. When a supplement web of half the width of the main web is used, a three-sheet product can be produced by adjusting and operating the delivery mechanism the same as in producing the twosheet products already described; or a sixsheet product can be produced by adjusting and operating the mechanism the same as in producing the scribed.

The cutting, folding, and associating cylinders 45 46 may, if preferred, be arranged at right angles to instead of parallel with the printing-cylinders, and in such case the webturners 47 will be arranged to act `upon only one of the webs d, so as to transfer it laterally to bring it over or under the other web. This arrangement of the web-turners is well known in the art, and need not therefore be particularly described.

In producing products shown in Figs. 15,17,

and 18 it may be desired that the sheets or' pairs of sheets which are associated after being folded longitudinally' should be pasted together along the line of the longitudinal folds. This, if desired, can readily be done by providing a suitable pasting-disk, 48, which runs in a fountain, 44, and is arranged to apply a line of paste to one of the sheets adjacent to lthe longitudinal fold-line as itis carried around upon the cylinder 45, so that when the two sheets or pairs of sheets are associated upon the cylinder 46 they will be united by this line of paste. The disk 48 is driven in any suitable four-sheet product already de! ranged to move to and from the cylinder.
