PAPER DELIVERING AND FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,554, dated April 26, 1881.

Application filed May 10,1880. (No model.) a

To all whom it may concern w Plainfield, in the county of Union and State Figure 1 represents a plan view of a machine embodying my improvements; Fig. 2, a frontside elevation of the same; Fig. 3, a longitudinal vertical section taken on the line mnFig. 1; Fig. 4, a detail view, showing a portion of one of the blast-pipes for deflecting the sheets; Fig. 5, a transverse vertical section taken on the line' y y, Fig. 1 and Fig. 6 a'detail vertical section of the sheet deflecting and imposing mechanism on an enlargedscale. 1

My invention relates principally to mechan ism whereby the sheets are separated after passing the cutting-cylinders, and are gathered or collected so, as to be delivered two or more in a single pack to'the folding mechanism.

The invention consists in special devices and combinations of devices for effecting these results, all of which will be hereinafter fully described, and the specialimprovements pointed out definitely in the claims. I

"I-u'thedrawings, A represents the main or supporting frame, which maybe an extension to the main frame of the'printing mechanism, it being understood, of course, that the mechanism herein described and shown is to be used in connectionwith printing mechanism, although I have not shown in the drawings any of the printing-cylinders, astheprinting mechanism constitutes no partof my present invention, and its arrangement relative to the cutting-cylinders, which are'here shown, will be readily understood by those familiar with machines of this description.

The cuttingcylinders, which are usually considered a part of the printing mechanism, are shown in the drawings, being represented by B and B at the front end of the machine, the former of which is a cutter-cylinder, and is provided with two perforating-blades, 1), arranged opposite to each other, and the latter is a corresponding grooved cylinder, and is provided with the usual cutting-grooves b for the reception of the blades. This cylinder in a the drawings, is shown four times the size of Be it known .that'I, WALTER Soorr, of,

the blade-cylinder, and consequently is provided "with four cuttingrgrooves.

Two, cylinders, G and D, are arranged in the same horizontal plane some distance in rear of the cutting-cylinder. These cylinders are of the same size,and in circumference are intended to be equal to the length of the sheets of paper plus the distance between the individual sheets after separation. The front'cylinder, O, is providedwith a'series of shallow grooves,'c,:running around it, and below triangular-shaped guides E arearranged in the space between the two cylinders. The front edge-of these guides just enters the grooves in the cylinder 0, whilethe rear edge is a little distance from the surface of the cylinder D, leaving suificient room for the sheet to run between it and 'the cylinder. These guides are shown in the drawings mounted on a rod, efthough they may be supported in any other suitable manner.

' A pair of tape-rollers,F and G, are arranged just below the rollers O and l), the biteofthe latter being in about the same vertical plane as that of theformer.

A series of upper tapes, H, are arranged to run around a tape-roller, It, just in rear of the cutter-cylinder; thenceto the front tape-roller,

F, under and around which they pass to the 7 cylinder 0, over which they are carried, and down between the cylinders G and D, passing underneath and back around the latter up over 1 the tape-roller h,- thence to and around roller h, at the rear upperpart of the main frame thence they pass upwarda'ud forward over a (roller, hi, and under a roller, h*, in the upper Tpart of the frame to the roller h. A similar 3 series of lower tapes, I, is arranged to run 1 around a tape-roller, i, just below the roller h; 1 thence to the roller F, underneath which they pass up between it and the'roller G, over the latter, to and around the rear of thecylinder D, up over the roller 11., to and around the roller 17, just below the roller h thence they run forward and downwardover the roller i, and underneath the rollers 71 and i arranged in the front partof the main frame, to the front roller, 1'. a

To accommodate the folding mechanism, which is arranged at'the' rear of the machine,

the same path as the outside tapes, H. The

central lower tapes, I, after leaving the roller 71/, pass to and down around the back of the roller 1?, arranged a little distance in rear of the former. Thence they pass down to and underneath the roller i from which point they take the same path as the outer tapes, I. Ob-

viously this arrangement will leave an open space at the rear of the machine between the outer sets of tapes. In this open space is arranged the mechanism for making the first fold in the sheets. In the drawings this mech- 1 anism is illustrated by the vibrating creaser J, operating in connection with two ordinary folding-rollers, j; but this is only for illustration, as anyknown folding devices may be used for this purpose.

A blast-pipe, K, is arranged a little below the cylinder 0 and forward of the shaft of the latter. A similar pipe, L, is arranged in the same horizontal plane a little below the cylinder D and in rear of its shaft. These pipes are provided with a series of apertures, k and 1, opening inward or toward each other, respectively, and arranged lengthwise of the pipes. These pipes run across the machine, and at one end are journaled in suitable hearings in the side frame, beyond which they project slightly, and are provided at their extremities with short crank-arms k and I. At the other side of the machine the pipes project also through bearings in the frame, and are connected by a screw-joint to the upper ends of elbows M, into the lower ends of which are inserted the ends of pipes m, which extend downward and join at the forward end of the pipe at, leading from the blower N It will be seen, therefore, that the pipes K and L may,

be turned slightly in their bearings, the screwconnection between them and the elbows permitting this movement without uncoupling. Just inside of these pipes are fixed bars 0, in

' which are inserted a series of short horizontal pipes, P, corresponding to the apertures in the pipes K and L, and extending inward toward each other over the shafts of the taperollers F and G. On the outside of these bars are seats 0, fitting the pipes, and arranged opposite the apertures therein. These seats are also provided with apertures leading to the short pipes P, as shown in Fig.6 of the drawings; but by turning either of the pipes K and L slightly, the apertures in them will be closed by being brought against the solid portion of the seats, thereby shutting off communication between these pipes and the short pipes P. The latter pipes do not quite meet,

but open toward each other just above the bite of the rollers F and G, so as to direct a blast of air toward the space between these rollers above their bite, as shown in Fig. 6 of the drawings. Their inner ends should bebeveled or cut away slightly on their upper sides so as notto project above the surface of the rollers, and thereby interfere with the passage of the sheets.

A shaft, Q, extends along the back side of the machine, and on this are mounted two cams, R R, which are provided with camgrooves 7'7",3116. are arranged relatively to the blast-pipes, so that the outer ends of the crank-arms Z enter the grooves 'r 1", respectively. Obviously, the rotation of the shaft Q, with the cams upon it,.will vibrate these crank-arms, and thereby oscillate the blastpipes K and L, and the cam-grooves are so arranged that the vibration of the respective crank-arms will alternate, so that when one of the blast-pipes is turned to shut off the blast the other will be in position to register with its set of pipes P, to permit the blast of air to issue from the latter.

A paste-fountain, S, is shown in the'drawiugs, mounted on a rock-shaft, s, and provided with the ordinary pasting-disk 8, these parts being arranged so that the disk will be about underneath the tape-roller F, and is brought in contact therewith by a vibration of the fountain, which is effected by any suitable means.

In the drawings, the lever s is attached to the rock-shaft, and is operated by a cam on one of the driving-shafts, which works against the free end of the lever. The pasting-disk is also rotated positively by suitable gearing. These parts of the mechanism are, however, all well known, and do not require a description in detail.

The pasting device is arranged centrally is intended to lay this line of paste along the sheet which is then carried up over the cylinder 0, the latter should be cut away slightly to correspond, so that no paste will be deposited on its surface.

By referring to Fig. 5 of the drawings it will be seen that one of the grooves, c, in the surface of the cylinder 0 is in the same vertical plane with the pasting-disk, and therefore accomplishes the object above mentioned.

Two gear-wheels, T T, are mounted on the end of the drive-shaft, at the front side of the machine, the former of which, on the outer end of the shaft, is a little larger than the latter,

Li M

th'a-tofithecutting1cylinders, and the roller F verse driving-shaft,the.wheel V also driving a train ofsuitable gearing, which communicates motion to the several cylinders andtaperollers wherever required. A'gear-wheei, V, isalso mounted on the same shaft with V, outside of thelatter, and is half the diameterof the former. The wheel U is made removable from its shaft, and on the upper side of thewheel V is another shaft, W, adapted to receive the wheelVin such position as to engage with the smaller wheelV, and also with the driving wheel T. ,Obviously, under this new arrangement of gearing, the deliveryand folding mechanism will be driven twice as fast as before, while the motion of the cutting-cylinders remains the same.

I have not described in'detail the construction andarrangement of all the gearingbelonging to the machine, as that will be readily understood from the drawings and the description below of the operation of the several devices, it being understood, of course, that the gearing and all other devices for Jmovin g any of the parts must be so constructed, arranged, and timed relatively as to produce the movements described below, and at the required times.

The directions in which the carrying-tapes and I, by which it is carried along to the roller F, where it is nipped between the lower tapes and the rollers, thereby separating the sheet by reason of the more rapid movement of said roller. Now, suppose the several parts to be in position represented in Figs. 3 and 6 of the drawings. The leading end of the separated sheet is carried up between the rollers F and G, and as the rear pipe, L, is in position to permit air to pass out through its series of pipes P, obviously the blast will be directed against the leading end of the sheet, thereby deflecting it forward so that it will be carried by the upper tapes to and around the cylinder 0, the blast being shut off at this time from the front set of pipes. As the sheet is carried down underneath the tapes between the cylinders O and D, the guides E direct it to the rear. In the mean time the following sheet has been carried up between the rollers F and G, and theblast-pipes have been shifted so that the air issues-frompipe K and its set-of pipes P, while it is shut off from therear pipes. Obvionsly, the leading end of the second sheet will thus be deflected to the rear and be carried by the lower set of tapes toward the cylinder D. Now, the cylinder 0 being; in circumference, as stated above, about equal to the length of the sheet plus the distance between the sheets after separation, or, in other wordspas this cylinder is geared to make one revolution for eaeh sheet perforated by the cutting-cylinders, it is evident that the leading end of the second sheet will join the leading end'of the first sheet just as it passes out from theguides E, and the united ends of the two sheets will be carried together into the tapes H and Louder the cylinder D, and thencenp over the cylinder at the rear, thetwo sheets thereby being placed one above the other, in which condition, as a single signature, they are carried up and back by the tapes overthe folding-rollers in proper position fortheopen ation of the creasing-blade. When the pasting device is employedits movement is timedso that a line of paste will be laid along the under side of the first sheet, and therefore when the two sheets are joined the secondjor lower sheet will be pasted to the first. It will thus be seen that with this mechanism I am enabled to make up two sheets into a single signature, preparatory to folding, without theuse of collecting-cylinders or any other similar devices, the mechanism above described being adapted to a paper of eight pages. must be made in the construction of the mechanism to adapt it to form a signature containing more sheets.

Now, it is sometimes desired to print a paper of half the size, or a single sheet, upon the same machine, and in order to permit this to be done I have made the provision for changin g the speed of the delivery and folding mechanism. Obviously, when the transmit ting-wheel U is changed to the front so that the paper is passing by it, and the sheet will run through one to the other around the cylinder D and be carried singly to the folder. With this arrangement for changing the speed the machine is adapted to double or single sheet papers without removing or changing any of the remaining devices.

Some other deflecting device may be substituted for the blast mechanism, and obviously some of the devices, especially those forim parting the required movement, maybe changed or others substituted therefor without affecting the principle of operation, and therefore I do not wish to be understood as limitin g my improvements to the precise construc- For papers of more ,pages changes.
