To all whom. it may concern:

Be it known that I, OSCAR RoEsEN, a citizen of theflllnited States, residing at New York'city, county of New York-and State of New York, have invented certain new and useful Improvements in Folding and Delivering Mechanism, fully described and represented iii the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in folding and associating mechanism for printing machines In arinting mechanisms of certain constructions, as, for instance, a press in which the form cylinders are provided with plates six pages across the cylinders and four pages around, the full capacity of the press cannot be utilized for the production of certain products, as, for instance, products having sixteen pages, without the use of two folders. This use of such presses is desir able for the'large production of such small products. The use of two folders, however, requires double mechanism for operating them, and when it' is desired to add a cover or an insert to the product, separate cover and insert feeding mechanisms for each folder and delivery is necessary. Such double folding and feeding echanisms therefore require a machine'of omplicated constructiomboth expensive to build and to operate.

It is one object of the present invention to produce an improved folding and associating mechanism whereby the full capacity of a press such as is above referred to may be utilized in producing small products of sixteen pages with a single folder.

It is a further object of the invention toproduce such a folding and. associating mechanism, including a single folder orde- .livery, which is compact and which can be arranged to cotiperatev with the usual numberof cover and insert feeding mechanisms where they are employed, so that the number of such cover and insert feeding mechanisms does not have to be increased.

'For a fullunderstandingof the invention,

reference may be had to the accompanying drawings, in which Figure 1 is a side elevation of so much of a printing machine as is necessary for' an understanding of the invention, certain parts being broken away;

Fig. 21s a front elevation, partly in section, vof the folding mechanism, the mechanism shown being arranged for use with sheets out two pages long;

Fig. 3 is an end View of the folding mechanism shown in Fig. 2, certain parts being shown in section, showing the grippers and operating cams in position to fold be at each revolution at one end of the folder;

Fig. 4' is a view similar to Fig. 3, showing.

the parts in position to fold off at every other revolution at the other end of the folder; Y

"Fig. 5' is adetail plan view of the cam operating mechanism for operating the folding-oif mechanism; and

Fig. 6 is a detail showing how the webs are run through themachine where three webs or ribbons hreemployed.

The particular machine illustrated in the drawing is capacitatedto produce products from a web printed six pages wide and four pages around the. cylinder, forty-eight pages being printed at each revolution of" a printing couple, and'for producing a product of sixteen pages, though it will be understood that other products may also be 'produced'andfrom a machine printing a different number of pages. In the present f instance, when forty-eight pages are printed at one revolution to produce full capacity of sixteen, this web will be slit into three ribbons each two pages wide, and in the machine illustrated two of these ribbons will be superposed in the usual manner by suitable turner bars 1, and thedouble and single ribbons will be forwarded side by side through the machine over a guide-roll 2. Suitable forwarding devices are' employed, and in machines embodying the invention in its preferred form, and as shown in Figs. 1 to 6, the webs will be cut into sheets at the half turn, that is, each sheet will be two pages wide and two pages long,

so that at each cutting operation a product of sixteen pages will be formed from the which in the particular instance. acts to forward the webs, such as cutting cylinder 3 cooperating. with a' cutter block; carrying cylinder' i. i I

After the sheets are cut from the webs superposed webs and a product of eight i pages from the single web. Cutting mechanism of the usual type-may be employed,

they are forwarded through guides 5 by each operation thereof, and a product from the other end at every other operation thereof. As shown, this is capacitated to receive the superposed webs and the'single web used in the particular machine shown, side by side, and operates to produce a product of sixteen pages from one endat each operation and a product of sixteen pages from the other end at every other operation. While the particular mechanism for effecting this may be widely varied, in the par ticular construction illu trated there is provided a folding and ollecting cylinder which is provided with sheet-taking devices which are supported so that they can be operated at different times longitudinally of the cylinder -thus providing for an unequal collection of the sheets on each side of the cylinder.

In the particular this cylinder, is of the usual hollow type having the flattened portion 11 against which the sheettaking devices hold the sheets. This cylin construction illustrated,

der is carried on the shaft 12 journaled in,

suitable bearings 13 mounted on the frame 14 of the machine. This cylinder is driven in any usual manner from the driving shaft 15 of the machine through the usual train of gears, the forwarding rolls 6, before referred to, being also driven through the same train. g

The folding and collecting'cylin'der 10 is,

in the particular construction shown, capacitated to receive sheets cut from the superposed webs and from a single web which are dorwarded to-it side by side and the cyliner operated to deliver a product from the superposed sheets at each revolution and a product from the single sheets at every other revolution. While the sheet-taking devices may be varied, in "the particular construc: tion illustrated these sheet taking devices are grippers. In the particular construction illustrated there are provided pairs of grippers 16, 1,7 and 18, 19. The grippers 16, 17 are located at one side or end of the cylinder and are carried on arms 20, 21, these arms being mounted on rods 22, 23. The rod 22 finds its bearings at one end in a central web 24 ofthe cylinder, and at marked 10 in the drawings,

is provided. with sheet-taking devices messes its other end in the cylinder head 25, and the rod 23 is mounted in arms 23 hung on a rod 23 which finds its bearings in the web of the cylinder, the grippers 18 being mount ed in arms similar to the arms 20, 21 which are mounted on a rod 27, the gripper rod 27 finding its bearings at one end in the central web 24 in the-cylinder before referred to, and at its other end in the other head of this cylinder 25 the grippers 19 are mounted similarly to the grippers 17, being carried by a rod 26 mountedin arms 26 hung on a rod 26 which finds its bearings in the web 24 and cylinder head 25 The gripper-operating rods 22,23, and 26, 27, are in this way made independent and can be operated to cause the grippers on each end of the cylinder to act at different times.

In the particular construction illustrated, referring to Figs. 3 to 5, the pairs of'grippers on each side of the cylinder include a long pair and a short pair. These pairs of grippers on each end of the cylinder will be mounted and operated'so as to have the usual opening and closing movement for taking and releasing the sheets. In constructions embodying the invention in its best form, however, for purposes hereinafter referred to, one pair of the grippers on each end of the cylinder willv be constructed and operated so that they may be given a movement relatively to the surface of the cylin 'der against which they grip, that is, a movement away from the path of movement of the surface of the cylinder, the other pair of grippers having their opening and closing movements always in the same place in the pagh of movement of the surface of the cylin er.

ed on the frame of the machine at each end.

of the cylinder, one such cam being providedfor/each of the gripper rods 22, 27, on

which the shortgrippers are carried, these In the construction illustrated, the. short grippers 16, 18 have no movement cams operating the gripper rods through cam rolls 30, 31 carried on arms 32, '33 fast on the gripper shafts 22, 27 and are closed E by the usual spring rod construction 32? and 33. I I

The long grippers 17 ,19 are, like the short grippers, so that the gripping and releasingon each operated from independent cams,

end of the cylinder may occur at different times, and these long grippers are, furthermore, operated so that in addition to their usual opening and closing movement, they are given a movement face of the cylinder.

relatively to the sur Theconstruction by which thls ls eflected may be varied, but in. 1130 35 trated as operated so that a product is foldthe construction shown" the ordinary opening and closing movement is given the grippers through arms 34, 35 on the gripper shafts 23, 26, these arms carrying cam rollers 36, one of which is shown in Fig. 3, and which operate in the grooves 38 of box cams 40, 41, loosely mounted on the shaft 12, .before referred to, one of these cams being located on each side of the cylinder.

The gripper shafts. 23, 26 are, as before stated, carried by arms 23*, 26, which are mounted on the shafts 23 26 and mounted on these latter shafts are arms 42, 43 having cam rolls 44 which also run in the grooves 38 of the box cams 40, 41. The box cams carry studs 46, 47, to which are connected connecting rods 48, 49, which in turn are connected at 50, 51 to lever arms 52, 53 pivoted on short shafts 54, -55 suitably journaled in the frame of the machine. Also pivoted to the short shafts 54, 55 are cam lever arms 56, 57, which are so arranged as to be connected to the lever arms 52, 53 by I bolts 39, and which carry .cam rolls 58, 59

running in grooves 60 of cams 62, 63, which are mounted 'on an operating shaft'64 extending across the machine. The cam lever arms 52, 53 are provided with extensions 65, 66 by which these arms can be locked to the frame ofthe machine by bolts 61 and prevented from operating, as shown in Figs.

2 and 3, this being done to permit the machine tobe operated as hereinafter described.

In the construction shown in Figs. 1 to 5, and as just described, the parts are illused off from the left hand end of the cylinder at each rotation thereof, and a collected product is folded off from the right hand end at every other rotation thereof. In other words, in the construction shown in these figures, and as so far described, the as a folding-0E cylinder at one end and a collecting cylinder atthe other at each rotation, and as a folding-off cylinder on both ends on every other rotation. When this construction is used, the

7 parts are as shown in Figs. 3 and 4, Fig. 3

showing the parts as positioned at the left hand end of'the cylinder, and Fig. 4 show-- ing them as positioned at the right hand end i. of the cylinder. When the-cyl1nder is thus operating to effect this, the cam lever arm 52, shown in Fig. 3,is-l oc ked, so that the gripper operating cam 38 is not shifted and the long set of grippers have simply an idle opening and closing movement, the sheets 1 being taxen by the short rlpperarms.

The folding-0E mechanism by which the sheets are delivered may be varied. In the construction illustrated, this fold-off mechanism includes a rotary sheet carrier 67 (which in the construction illustrated is a cylinder) mounted on a shaft 68 suitably journaled in the frame of the machine. This ,7 feeders.

delivery cylinder 67 is provided with two folding off or n pping jaws, only one of which is shown, these folding 0E jaws taking care of the products of cylinder 10'.

These nipping jaws, marked generally 69, are operated by acam roll *70'from a movable cam 71 on the shaft 68, it being understood that this constructionis duplicated on the other side of the delivery cylinder 67.

These foldin off iaws cotiperate with the ing proportioned so that when the box cams are in proper position, through the cross over arms, one of the cams 71 will be moved so that it will be in proper position to cause the nipping jaws to take at the right time,

as shown in Fig. 3.

From the delivery cylinder 67 the products are taken by suitable belts 7 5 to the, usual cross-folding mechanisms 7 6, only one of which is shown, where they are given their final fold. If desired, stitching mechanisms, one of which is shown in dotted lines marked 77, may be employed for stitching or stapling the products. 1

In machines embodying the invention in its best form, means may be provided for covering side to the cylinder 10, which are or may be of the usual constructon. By the employment of the cylinder 10, constructed as described, the two products, which are formed thereon may have covers added-by the employment of only two cover feeders and have the inserts added by theuse of .two inset The cover feeders may be of the usual construction, and are indicated generallyby the numerals 78, 79, these cover-- feeding mechanisms alternately feeding covs ers to the product, two such mechanisms being necessary to enable the covers to be fed in at the speed of the production of the product. .The inset mechanism is also of the usual construction and is indicated gen- 100. the sheets vas they advance side by erally by the numerals 80, 81, this inset I mechanism being employed as is usual for insetting specially printed sheets- Where, as in the. particular constructlon shown, a

product two, pages long is being produced 'and a :cover is to be added to this product,

which is but one page long, means are provided for taking this cover. Thesemeans may be of any suitable character, such as the usual taking pins 82, shown in dotted lines in Fig. 3.

The operation of the machine may be briefly stated as follows, it being understood ply webs being forwarded side by side and" cut at half turn, that is, into sheet lengths two pages long longitudinally of the web. When this product is to be produced, theL cylinder 10 acts as a collecting cylinder on I one end and as a folding ofi cylinder on the other end at each revolution. Assuming the two-ply sheets to be forwarded to the. left hand side of the cylinder shown in Fig. 2, the parts "will be in the position shown in Fig. 3 for this section of the cylinder. As the two superposed webs form a product sixteenpages when folded, the cylinder at this end delivers to the delivery cylinder two superposed sheets at each revolution When this is done, the gripper 16 takes the leading end of the two'sheets which are car-' ried around the cylinder and folded ofi by the nipping jaws 69, the cam 71 being in position to allow the folding ofi' jaws on the left hand end of the cylinder 67 to operate at each revolution, as shown in Fig. 3. lVhen the machine is thus operated the cam 38 is so positioned that the movement of the grippers 17 is an idle movement, taking place after the grippers have passed'out of the path of the leading end of the sheet, so as to leave the short grippers clear to take the sheet.

As only one sheet is going to the other side of the cylinder, that is, the right hand end of the cylinder shown in Fig; 2, it is necessary to collect from this cylinder two products to produce sixteen pages. This is effected, as before described, by positioning the parts as shown in Fig. 4, in which the cam operating arm 53 is unlocked and free to be reciprocated by the cam arm 57 and cam roll 59, which acts to shift the cam 41 so as to give the long grippers their proper opening and closing movements. When the machine is thus operating, the long grippers take the leading end of the first sheet and carry it around the cylinder, the short grippers taking the leading end of the next succeeding superposed sheet and acting to carry .both the sheets around thecylinder, the long grippers19 having their opening movement delayeduntil the short grippers have seized both sheets. =The shiftingof the cam also.

through the cross-over 73 shifts the corresponding cam 71 and causes the folding jaws to be ina position to fold off the product at every other turn ofthe cylinder, so

that a product of sixteen pages isfolded ofl this end of the cylinder at every other revolution thereof.

While, as shown and described, the left hand end of the cylinder shown in Fig. 2

- folds ofi' at every revolution it will be understood that by arranging the parts as shown in Fig. 4:, this end of the cylinder scribed in its preferred form, but it is understood that many changes and variations can be made in the particular construction and arrangement of theparts, and that changes ,may be made in the arrangement and operation of the mechanism whereby a Wide variety of products may be produced,

and that such changes and variations may be made without departing from the invention'. a
