DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 248,888, dated November 1, 1881, Application filcdlLIay 13,1881. (N0 model.)

To all whom it may concern:

Be it known that I, \VALTER Scorn, a subject of the Queen of Great Britain, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Paper Printing and Folding Machines, which are fully set forth in the following specificatiomreference being bad to the accompanying drawings,in which Figures 1 and 2, taken together, represent a front-side elevation of a machine embodying my improvements, Fig. 1 showing the rear portion of the machine and Fig. 2 the front portion; Fi .3,the back-side elevation of the rear portion of the machine; Fig. 4, a rear-end elevation of the machine, the outside gearing being removed; Fig. 5, a longitudinal vertical section of the rear portion of the machine on the line as 00, Fig. 4.; Fig. 6, a detail front elevation of the friction device at one end of the paper: roller; Fig. 7, a plan view of the same; Fig. 8, a plan view of the shifting and brake mechanism for stopping and starting the machine; Fig. 9, a side elevation of the same; Fig. 10, a detail plan of the sheetturning device; Fig. 11, a detached view of the sheet-turner constructed to be fixed; Fig. 12, a similar view of the sheet-turner in the term of a roller; Fig. l3,adetail plan, on an enlarged scale, of the device for mounting the roller; Fig. 11, a detail plan of a modification in the sheet turning mechanism; Fig. 15, an end elevation of the same; Fig. 16, a side elevation, showing a second modification of the sheet-turning mechanism; Fig. 17, an end elevation of the same; Fig. lo, a plan view of a third modification ot' the sheet-turning device; Fig. 19, a side elevation ofthe same; Fig. 20, a plan view ofa fourth modification of the sheet-turning device, and Fig. 21 a side elevation of the same.

Myinvention relates to certain improvements in web-printing machines with folding attachment, the object being to print from two rolls on the same press, and then associate the two printed webs so that they may be folded together, or to print from a single roll, the web being divided longitudinally and the two parts associated before delivery to thet'olding mechanism.

I will proceed to fully describe the construction and operation of a machine embodying several parts of my invention, and the special improvements which it is believed are new, and which I desire to secure by Letters Patent, will then be pointed out definitely in the claims.

The printing mechanism shown in the drawings is substantially the same as that shown in Letters Patent No. 221,704, granted to me November 18,1879. 1 shall not, therefore, describe in detail the several parts of this mechanism, but shall mention them only in a general way, and refer to the above-named patent for a more specific description.

The main frame A is of any suitable construction to receive and support the entire mechanism for printing. associating, and folding the sheets, all of the devices being mounted in or on this frame.

The rolls of paper B are mounted on a single spindle, I), supported on standards I) at the front end of the machine. There is but a single spindle l), but it is made of sufficient length to accommodate two rolls of paper, B, whenever it is desired to print two webs at the same time, both rollsbeing mountedon the same spindle. The rotation of the spindle is regulated and controlled by a friction device, B, and an adjusting device, B like those described and shown in my prior patent, mentioned above, so that both rolls of paper are mounted on and carried by the same spindle and controlled by a single friction device.

The inking mechanism at the front end of the machine is the same as in my prior patent, and the web or webs of paper receive the first impression from the printing-cylinders O G, as in the same patent, the web being conducted to these cylinders over rollers c 0. (Shown in Fig. 2 of the drawings.) A cutter, 0 is arranged above the latter of these rollers in position to divide the web lengthwise when the printing is done from only one roll; or, it desired, the cutter may be used to divide all of the webs. This cutteris of ordinary construction, and a more detailed description is not necessary here. The web or webs then pass over the cylinder D, and between it and a second cylinder, D, these two cylinders constituting the second set of printing-cylinders, the ink being supplied by a second inking mech anism like that shown in my prior patents,and which is fully shown in Figs. 1 and 5 of the drawings in this case. After receiving the sec- 0nd impression, the webs pass underneath a roller, d, and thence rearward to suitable turning devices, which I will now describe.

The shcet-turucrs E E are arranged diagonally to the path of the webs, about at an angle ot' forty-five degrees, the first one, E, extending entirely across the machine, and the second one, E, some distance in the rear of the former, and extending across only a portion of the machine, at the front side thereof, the distance between the tnrners,taken in the direction of the path of the webs, being equal to the width of one of the webs which is to he turned.

I have shown in the drawings two construclions of sheet-turner. The first one, E, is a stiff bar, such as has been used for a like purpose in other machines. The second one, E, is aroller monn ted in suitable bearings, e, which are provided with a friction or tightening device, e, by means of which the ends of the turner are clamped so as to permit just alittle movement of the roller from time to time, to occasionally present a new surface to the paper.

A pasting-blade, F, is arranged just in front of the first sheet-turner and extends only over the web at the back side of the machine. This blade takes paste from a roller, F, which is supplied from afountain,f. The pasting-roller is regularly driven by suitable gearing, and the pasting-blade is driven by eccentric-gears /"f the first of which is on the same shaft as the blade, while the second is mounted on a suitable stud and is driven by a geacwheehf, on the shaft of one of the inking-cylinders, which engages with a regular gear, f, on the same stud-shaft as the eccentric f This train of gears just described is so arranged as to give aquick movement to the pasting-blade as it is brought down in contact with the web, and a slow movement (lilting the rest of its rotation, so as to prevent the throwing olfof the paste from the blade by centrifugal force. Now, if two rolls of paper are used and the two webs are run through the press side by side, obviously the web at the back side of the machine will be operated on first by the first sheettnrner, E, which turns this web at right angles to its former line of travel, as shown in Fig. 10 of the drawings. This web is then carried out, at the back side of the machine, over the roller Gr, set at right angles to the printing-cylinders, and passes thence back under the turners to a pair of rollers, G G near the back side of the machine and below the turners, as shown in dotted lines in Fig. 4 of the drawings. In the mean time the other web on the front side of the machine has been turned in the same way by the sheet-turner E, the under side of which is setalittle lower than the under side of the turner E, thereby carrying the second web a little below the first after it is turned. As will be seen in Fig. 10 of the drawings, this web will be carried out toward the back side of the machine directly underneath the first web, and is carried over the roller Gthe upper one of the pair just mentioned. A set of tapes, 9, may be arranged on the roller G, and a tape roller or pulleys, g, set near the center of the machine forthe purpose of leading the ends of the web through after being turned. The front side of the web is carried out and around the roller G, where it meets the first web, and the two being joined pass through between the rollers G G the extra travel of the first web beingj ust sufficient to bring the two together in proper position when associated. In order to secure this result with certainty, the roller G is made adjustable back and forth in its bearings. In the drawings I have shown an ordinary adjustingscrew, g for this purpose; but any suitable device may be employed for this adjustment. The roller G is also provided with a longitudinal groove, 9, (shown in Ft". 3 of the drawings,) and the revolution of this roller is regtr lated so that the line of paste previously laid on the back web will always be brought over this groove as the web passes over the roller, thereby preventing the paste coming in contact with the surface of the roller.

In order to strengthen the roller and preserve the regular tension upon the wcb as it passes' around the roller Gr, short sections 9 are left in the groove. entire, and similar spaces are cnt out of the edge of the pastingblade, so that no paste will be spread on those parts of the web corresponding to the sections. The two webs, after being associated as described above, are carried downward and inward from the rollers G G as shown in Fig. 4 of the drawings, to cutting and folding cylinders H H H, arranged at right angles to the printing-cylinders, as shown in the figure of the drawings just mentioned. It is not necessary to describe the construction and operation of these cylinders here, for they are precisely the same as shown in Letters Patent No. 220,873, granted to me October 21, 1879, to which reference is made for a full description. The associated webs are acted upon as one by these three cylinders, the sheets being severed and receiving two parallel folds, as described in Letters Patent No. 220,873. The three cutting and folding cylinders are made of a length twice the width of one of the webs of paper, for a purpose which will be presently explained; but in the operation above de- IIO scribed obviously the associated webs will be acted upon at one end only of the cylinders, in this instance the rear end, as shown in Fi 3 of the drawings, though this order may be reversed. The twice-folded sheets as they are delivered from the cylinders are received by suitable tapes, h h, by which they are carried upward and outward toward the front side of the machine, over a pair of ordinary foldingrollers, I, set at right angles to the preceding cutting and folding cylinders, as shown in Fig. 5 of the drawings, and under an ordinary vibrating creaser, I, arranged to operate in conjunction with these folding-rollers. As the folding sheets are delivered to this folding mechanism they are creased into the bite of the rollers I'm the ordinary way, thereby receiving a third fold at right angles to the first two, and are delivered downward into a receivingtrough, J, in front of a reciprocating packer, K, by means of which they are delivered, properly folded, at the rear end of the machine.

I will 110w proceed to describe an im provement in the mechanism for operating the vibrating creaser.

The main driving-shaft L is located substantially as in my prior patent, first mentioned above, and is arranged to make one revolution for every sheet of printi n The main drivinggear lis fixed on this shaft at the front side of the machine, and just outside of it is an eccentric-gear, M, also mounted on thesame shaft, which engages with a similar eccentric-gear, M, mounted on a stud-shaft at the front side of the machine, as shown in Fig. l of the drawings. Inside of this last eccentric-gear, and connected to it, is an ordinary eccentric, m, around which is arranged the usual strip, which is connected by a rod, m, to an arm, n, attached toarock-shaft,l l,on the frame above the eccentric. This rock-shaft is also provided with another arm, n, outside of the former, which is connected by a rod, TS, to a crank-arm, i, on the rock-shaft t, to which the arm that carries the creaser I is attached. The two eccentricgears M M and the eccentric m are arranged relatively to each other so that the creaser I will have its quickest motion at the lower part of its descent when it has operated upon the sheet, thereby producing a quick movement just as the creaser enters the bite of the folding-rolls and is withdrawn therefrom, while during the rest of its movement it will have a comparatively slow motion.

The mechanism constructed and operate 1 as described above will produce a paper of eight pages pasted and folded three times.

If it is desired to prepare supplements, or a paper of four pages instead of eight, it is only necessary to make the following changes: In the first place both webs are led over and turned by the one sheet-turner, E, which obviously will simply turn the webs without bringingthem one over the other thence the turned webs, traveling side by side, are carried to the back side of the machine over the same roller G, which is made of a sufficient length to accommodate both webs, and thence directly to the cutting and folding cylinders, which operate upon the sheets as they pass through side by side, just as previously described. Evidently, however, as two folded sheets will now be delivered from the cylinders, one in frontof the other, (speaking with reference to the machine,) it is nrccssary to provide a second set of devices for making the third fold. in the sheets. This mechanism is shown in Fig. 5 of the drawings, in which another set of foldingrollers, 1 and a vibrating creaser, 1 are pro.- vided, constructed and operated prcciselylike therollers I and creaser I described above, and arranged in front of the latter in suitable position to receive the other set of folded sheets as they are delivered from the other end of the folding-cylinders, in the same way as already described for the first set. The sheets folded by this second set ofdcvices are delivered down between a set of tape-pulleys, 0, directly below, over which two sets of tapes 0 0 are passed, extending toward the rear of the machine and running over tape-pulleys or rollers 0, arranged below the front roller of the fold-' ing-rollers l, as shown in Fig. 5 of the drawings. The folded sheets are carried by these tapes toward the rear of the machine under the set of folding-roilers first described, where they are turned downward by suitable curved guides, 0 and are delivered side by side with the folded sheets delivered from the rollers I, the carrying-tapes being timed to accomplish this purpose. In order to regulate the tapes so as to accomplish this result I place a roller, 0 across the central portion of the tapes, and make it adjustable vertically, so that if the folded sheets are delivered a little too quick they may be regulated by bringing the roller against the tapes, thereby making a bend in the path of the sheets and increasing their travel snfficiently to effect their delivery at the proper moment to correspond with the sheets delivered from the other side of the foldingrollers. This roller may be placed in either the upper or the lower tapes. In the drawings I have shown it placed in the upper set, as being more convenient.

The arm of the second creaser, I is attached to the rock-shaft N, so that it is operated by the same eccentric as the creaser l, with the same results, and the movements of the two creasers are simultaneous.

One of each set of the folding-rollers I l is provided at its front end with a beveled pinion, by meansot'which therollers are driven through shafts 71 71 provided with suitable beveled pinions, and driven from the main gear on the main driving'shaft.

The packer K is connected to a slide-bar, 7c,

Fig.5, underneath the receiving-trough, to the front end of which is connected the lower end of an arm, k, mounted at its upper end on a stud. A short arm, k is also mounted. on the same stud and connected to the arm K, or cast therewith. An eccentric, K, is fixed on the main shaft, the strap of which is connected by the eccentric-rod k to the arm k thereby communicatingthe necessary reciprocating motion to the sliding bar and packer.

The cutting and folding cylinders are driven from the main shaft by means of miter-gears 1 l (shown in Figs. 3 and 5 of the drawings,) the rollers being carried together at the rear end of the machine, as shown in the same drawings, from which gears the rollers at the back side of the machine are also driven, as shown inFig. 3 of the drawings.

In Figs. 8 and 9 of the drawings 1 have shown a device for instantly stopping the machine when the belt is shifted. The main driving-pulley L is fixed to the main driving-shaft L, and the usual loose pulley, L is arranged by its side in the usual manner, with the customary devices for shifting the band. A brakeshoe, P, is provided for the driving-pulley, mounted on the upperend of an arm,p, pivoted at its lower end to a suitable support, 19, on the floor or elsewhere.

On the reciprocatingrod Q, to which the bandshit'ter is attached, is an inclined or wedgeshaped cam, q, arranged just back of and with its cam-face against the brakeshoe, the relation of the parts being such that when the belt is shifted from the driving to the loose pulley the brake will be set up against the former and instantly stop the machine, and of course will be releasedwhen the ban (1 is shifted back. The shifting-rod Q is opera ted by arockshaft, Q, at the front side of the machine, provided with hand-levers, as shown in Figs. 1 and 2 of the drawings.

In the description above I have explained the operation of the machine in connection with two separate webs mounted in rolls on the same spindle; but, if desired, a single roll, with a single wide web for the entire machine may be employed, in which case, however, it will be necessary to bring the cutter 0 into operation for the purpose of dividing the web centrally,or,in case the sheets are to be folded singly, and but one turner used, as described above, they may be separated by a cutter arranged and operating substantially as shown in my prior patents above mentioned. Obviously, by increasing the width of the machine and duplicating the lltteSSdly devices, more than two webs may be turned and associated, after printing, before cutting and folding, as described above, and the different webs may even be brought together from ditferent printing-machines, if desired.

1 have not entered into a detailed description of all of the gearing and other ordinary de- "ices necessary in the construction of my machine, for their construction and arrangement will be readily understood by those skilled in the art from the description given above and the several figures ot' the drawings.

Figs.14 to 21 show modificationsofthesheetturning devices. The web at the back side of the machine is designated 1, and that at the front side 2. In Figs. 14 and 15 the sheetturners R and R are set at an angle to each other, with their rear ends inclined inward, the latter being in a plane lower than the former. The webl is turnedoverand nnderthe turnerR, which will cairy it sidewise forward, thence over a roller, 0', set at right angles to the printing-cylinders, thence toward the back side of the machine to another roller, 4, whereitmeets the web 2, which in the meantime has been turned under and over R, whence it is carried sidewise inward to the roller *r, where it is associated with'web 1, and the two together,

passing over this latter roller, are carried on to the cutting-cylinders below.

In Figs. 16 and 17 another modification is represented, which is similar to the preceding, except that the web 2 is turned under the turner It instead of over it, and is carried thence to a third roller, 4", instead of to the roller r, and the webs are associated after they pass the roller 1, as shown in Fig. 17 of the drawings.

In Figs. 18 and 19 the turners S S are arranged vertically. The webs 1 and 2 pass between the rollers 88 before reaching the turners, which hold them in proper position. The web 1 passes around the outside of the turner S and the web 2 around the outside of the turner S, and after passing the turners both webs are carried directly to the cuttingcylinders, where they are associated. In this modi fication the cutting-cylinders must also be set in a'vertical position. In Figs. 20 and 21 a modification is shown varying slightly from the preceding. The turners are, however, set close together, and the two webs pass between them, being thus turned and associated at the same time, and passing thence directly to the cutting-cylinders. In this modification, however, the tnrners and cutting-cylinders must be set slightly inclined toward the front end of the machine, for it will be noticed that the turners are located at the inner margins of the webs,and thereforein twisting thesheets there will be a slight change in their relations as they pass from the turners, while in the former case, the turners being located centrally of their respective webs, the latter will be turned, so that as they leave the turners they will move in planes perpendicular to their former paths.

in using any of these modifications it will, of course, be necessary to change correspondingly the position ot'the parts operating in connection with the cutting-cylinders. The webturners first described and shown in Fig. 10 ot' the drawings may bemountedin a frame in such a way as to be adjusted with reference to each other to suit webs of different width. This may be accomplished by a variety of devices not requiring description.

I am aware of English Patent No. 3,056 of 1875, in which the web of paper is turned by a roller or shaft placed in an inclined position across its path; and I do not claim anything shown in said patent.

Having thus described myinventionflvhat I claim as new, and desire to secure byLetters Patent, is
