CYRUS IVALLS, OF TAYLORVILLE, ILLINOIS.

AUTOMATIC NEWSPAPER FOLDING AND ADDRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 590,733, dated September 28, 1897.

Application filed May 17, 1893. Serial No. 474,571. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, CYRUS N. WALLS, residing at Taylorville, in the county of Christian and State of Illinois, have invented a new and Improved Automatic Newspaper Folding and Addressing Machine, of which the following is'a specification.

My invention relates to a combined folding and addressing machine adapted for use in connection with'the modern newspaper-printing presses, from which it receives the printed sheet and in successive operations folds it and delivers it to the addressing devices, from which it is fed to the wrapping mechanism or is discharged onto a suitable receivingtable.

The features of novelty will be hereinafter pointed out.

In accompanying drawings, Figure 1 is a perspective view illustrating the general construction and arrangement of parts of the machine. Fig. 2 is a vertical longitudinal section of the machine. Fig. 3 is a transverse section of the same, taken on the line 3 3, Fig. 2. Fig. 4 is a top plan view thereof. Fig. 5 is a detail vertical section of the same, taken on the line 5 5, Fig. 3. Fig. 6 is a detail plan view of the addressing mechanism Fig. 7 is a perspective view of the first-fold blade and its operating mechanism. Fig. 8 is a detail view illustrating one way of driving the upper or feed cylinder shaft. 9 is a detail perspective view of the feederframe-adjusting devices. Fig. 10 is a detail view of the addressing mechanism. Fig, 11 is a diagrammatic view of a modification hereinafter referred to.

To clearly set out the operation of the machine and to render its construction the more readily understood, I shall in describing such construction begin at the point where the printed sheet enters and describe the several and 2, it will be noticed the operating mechanism is mounted on a suitably-constructed iron frame A, in practice of substantially the Fig shape shown, .at the upper front end of which is journaled what I term the main or feed cylinder B, it being mounted in bracket-arms a a and may be driven'from the printingpress drive mechanism by means of a chain belt I), which passes over a sprocket-wheel b on the cylinder-shaft B, as shown in Fig. 1, or by a chain belt b which passes from the printing-press drive mechanism over a drivewheel 0 on the main drive-shaft, up over an idler c on the main frame, and held to engage a sprocket-wheel b on the cylinder-shaft, as clearly shown in Fig. 8, the latter arrangement of drive devices being preferred.

' The feederdevices D comprise a main frame having side arms d d, pivotally supported at their inner ends on the cylinder-shaft B (see Fig. 9) and formed with downwardlyprojecting slotted sector-arms (V, with which engage set-screws (1 held on the lower end of pendent extensions a of the main frame, such construction being provided to permit the receiving end of such platform being adjusted vertically relatively to the dischargereel X of the printing-press.

It will be noticed by reference to Fig. 2

the outer ends of the arms d are connected that the receiving tapes or fingers of the feeder project into the delivery-cylinder between the wheels thereof, beyond the outer rim of said wheels, so as to bisect the circu 1nference in order to turn or divert the sheet toward the folder and prevent it from following the contour of the wheels until it falls to the floor between the press and the folder.

Heretofore the receiving fingers or tapes of a folder have been set close up to or against the peripheral edge of the delivery-wheels. In such arrangement, however, the paper cannot be uniformly and successfully delivered. It will thus be seen that by projecting the bifurcated arms beyond the end of the frame D such arms can be projected between the wheels of the cylinder, as shown in Fig. 2, to a desired degree without being in the path of the oi dinary gripper devices of such cylinder.

G indicates the main table or platform, formed of transverse bars g g, supported at their ends on the end bars a a of the main frame, and a metal sheet g, centrally slotted, as at Endless bands II pass over this platform and at the front end over the cylinder B, then over a guide-roll 72 back under the said platform, and then over a series of pulleys h h, mounted in bearings h 7L2, adjustably secured on the end beams a as most clearly shown in Fig. 2.

At the outer end of the main table or platform G are adj ustably secured a pair of stops I I, at the outer end of each of which is secured and projected inward a spring or clamp guide-finger J, the purpose of which will presently appear. At each end the main frame has upwardly-extendin g standards K K, with which are formed transverse arms 70, which project horizontally over the ends of the platform G to a point beyond the slotted way g then curve downward and extend in a lower horizontal plane, as at and terminate in foot portions 70 the latter portion 70 of the side arms forming bearings for the supplement-platform L, the special construction and arrangement of which will appear later on.

M indicates a drive-shaft journaled in the side arms 70, which in the practical construction is mounted for a continuous rotation during the operation of the machine, it having a sprocket 972, over which passes an endless sprocket-chain m, which in turn passes over idlers m m journaled on the inner standard K, and down over a sprocket m on the main drive-shaft C. This shaft M operates the first or main folding-blade, and such blade, it should be stated, to accomplish its purpose must have a vertical intermittent reciprocating motion over and through the slotted way To transmit such motion from the continuously-rotating shaft M in a positive, simple, and effective manner, I employ the intermediate connections shown most clearly in Fig. 8, by reference to which it will be seen that to the outer faces of the standards K are pivoted swinging arms N, the outer ends of which have link connections 7H1 with the blade 0, which blade has guide-arms 0 0, held for vertical movement in guideways k k on the inner faces of arms 75, such arms N being also provided near their outer ends with crank members P on their inner face, which are pivotally connected with crank members M on the ends of the shaft M.

By providing operating devices for the folder-blade O in the manner shown and described it will be manifest that at each complete rotation of the shaft M the arms N will be carried up and down and temporarily held in their horizontal position, and while they will freely reciprocate at a point below the axis of the shaft M they will not be carried above same. Thus should the blade 0 be in its lowermost position, as shown in Fig. 7, the cranks ll will be at their lowest thrust. Now as such cranks rise they will carry the arms N up with them until they (the cranks M) reach their horizontal position, at which time the axis of the cranks M and P will be in alinement, and the blade 0 being at this time under the arm 7a the axis of the crank P becomes a fixed fulcrum until the cranks M and P pass beyond their uppermost thrust and they reach their opposite horizontal position, when the blade and its arms will descend. It will thus be seen that during approximately each half-rotation of the shaft M the blade 0 will be held to its upper position. It will also be readily understood that by connecting the blade 0 to the arms N by the link connection a vertical movement of the blade is obtained from the swinging or are movement of the arms N.

Journaled longitudinally under the platform G are a pair of rollers Q Q, which form the first folders and are arranged one at each side of the slot or way 9 to receive the sheet as it is pressed down through such way in the manner hereinafter stated. These rollers Q Q, which extend entirely under the platform G, as most clearly shown in Fig. 3, are journaled in bearings in the side beams a a and the shaft of one of such rollers Q, which forms the drive-roller, is extended and provided with a sprocket g, which receives motion from the chain 1-, which also passes over a sprocket r on a short shaft R, journaled on the main frame and driven by the belt r which passes over a drive-wheel 0- on the main shaft 0 and a sprocket-wheel 1" on the shaft R.

The operation of the machine so far as described is explained as follows: The printed paper sheet, which we will assume is an eightpage sheet, as it passes from the press is earried down over the platform D, under the roll E, between the tapes Hand upper guidetapes I-I over the main platform G, which carryit across until the front edge thereof strikes the stops I I, the ends of such edge passing under the clamp-guides J, which clamp-guides hold the sheet from rebounding. At this time the blade 0 will have been lowered to engage the paper sheet to force its central portion down into the slotted way 9 and as it does so it pushes the folded edge between the rolls Q Q. Before following the course of the paper fur ther, I will describe the supplement-feeding devices, as the supplement and the main sheet are carried through the succeeding operations together.

The supplement-table L is mounted on lateral flanges 76*, formed on the inner faces of the arms 70, its front edge being close up to the path of the blade 0. At a point in front of the blade and parallel with the front edge of the table L is an adjustable stop S, formed with an upwardly inclined or beveled face, it being held for adjustment by the set-screws IIO . chine.

into contact with rolls T T.

s s and the arms 8 s, pivoted to the arms 70. It will be noticed by reference to Fig. 3 the stop-bar S is so arranged relatively that the supplement-sheets, which lie on the platform L and which are fed by hand, as they are fed forward will pass over the way g between the platform L and the bar S, and as the end of the paper engages the bevel-face of such bar it is arrested and curls slightly upward, as shown, to form a lap or fold edge, with which the blade 0 engages on its downward thrust. When a supplement is to be run through the machine, the blade is provided with spur-fingers 0 which grip the end of the sheet and carry it positively down inside the main-sheet center fold. By making the stop S adjust able a longer or shorter lap-fold on the supplement may be provided for.

Referring now to Fig. 3, it will be readily apparent that after the paper has received its first or central fold and the supplement fed inside it it passes with its fold end between the rolls Q Q, which complete the first fold, and which serve to start such sheet onto the next set of rollers, which are indicated by T T, and are arranged at right angles to the rollers Q Q and centrally of the machine. Endless bands U are passed over the roll Q, under the roll Q, and over guide-pulleys U on the front bar a" of the main frame, in advance of which stop-plates are provided, which limit the movement of the paper as it is fed toward the second-fold rolls. To hold the paper down and even against the carrier-tapes U, a pair of endless guide-tapes U are provided, which pass over rolls V on the inner pair of standards V and over the roll Q, as clearly shown in Fig. 3.

Projected inward from the front side and centrally over the second-fold rolls T is a gravity folding-blade Z, which is secured at its outer end to a vertically-movable rod to, guided in eyes or bails w on the front bar a, and which has at its lower end a bifurcated socket in which is journaled a frictionroller 10 which rides upon a cam Y, mounted upon the main drive-shaf t O, as clearly shown in the drawings. This cam, it should be stated, is so adjusted relatively to the feed of the paper that when the first-fold sheet reaches the stops V the blade Z will drop and double the first-fold sheet up and force its fold between the second-fold rolls T, after which it (the blade) is again moved up by the cam and held up until the next folded sheet comes in its proper place. So far as described it will be seen the paper as it receives its first fold is carried at right angles toward the front side of the machine and is brought These rolls also comprise a drive-roll T, over which endless bands pass, and a guide, under which the bands pass, the front ends of such bands passing over guide-pulleys adjustably mounted on a cross-bar a at the front end of the ma- The drive-roll T. has a sprocket over which passes a chain belt 1?, which receives motion from a sprocket i on a driveshaft O mounted on the frame A at right angles to and geared with the main driveshaft 0, as shown in Fig. 2.

It will be noticed by referring to Fig. 3 that the folded paper as it passes between rolls T T has its second fold completed and is carried at right angles to its previous feed over the third-fold rolls A A, journaled in the end bar a and a cross-bar a. Projected centrally over the rolls A A is the thirdfolder blade B which is constructed similar to blade Z and is operated by a cam O on the shaft O.

The drive-roll A has a sprocket-wheel 61 which receives its motion by the chain (1 which passes over an idler d and engages the sprocket d and passes over a sprocket c on the address-printing or plunger-operating cam-shaft O and a sprocket-wheel on the flyoperating drive-shaft D presently referred to, and receives motion from a sprocket-wheel c on the main drive-shaft O, as most clearly shown in Fig. 3.

E indicates the bands which pass overthe rolls A A and over guide-rolls 6 ad j ustably secured on a cross-beam a of the frame, and such tapes lead the triple-folded sheet over the fourth-fold rolls E E mounted in the cross-beam a and a cross-beam 0.

F indicates the fourth-folder blade, which is constructed similar to blades Z and B except that its rod f is connected to a trans versely-pivoted arm G the front end of which has a bifurcated bearing g in which is journaled a roller 9 which engages an operatingcam H on the drive-shaft O The drive-roll E has a sprocket E, which receives motion from the sprocket-chain 25 as clearly shown in Fig. 2.

The paper, after it receives its fourth and final fold, is carried to the outer end of the machine by the endless bands J which pass from the drive-roll E to the fly-shaft K which is located adjacent to and operates in connection with the addressing devices, which are most clearly shown in Figs. 1, 2, and 6.

' Journaled on a bar a on themain frame is an addressing-wheel L on the peripheral edge of which are secured the address-types, which are secured in any well-known manner, but preferably in sections, as shown. The inner end of the shaft Z of the Wheel L is also j ournaled in a depending yoke-frame M and on such shaft is fixedly held a worm-gear l", with which meshes a worm-pinion n on a shaft N which shaft has a sprocket-wheel n, which is driven by a chain a", which engages a sprocket-wheel n on the shaft O and to hold the wheel L from a too free movement and also to serve to. tighten the chain afriction-disk O is placed between the wormgear Z and the yoke-frame, as clearly shown in Fig. 2.

It will be manifest that in the practical construction of the machine the several drive mechanisms are so adjusted and constructed relatively to each other that each set of devices will operate at predetermined intervals, whereby to successively fold and feed the sheet and deliver it to the addressing mechanism, the addressing-wheel-operating devices being so adjusted as to turn it (the wheel) one address as each folded paper is fed onto the fly.

Projected out from a cross-bar a is a bedplate consisting of parallel arms P which project centrally over the upper central point of the wheel L between which arms the proper address-type appears at each movement of the plunger or printing arm Q This plunger-arm is mounted on the rockshaft C journaled in bearings 0 and such rock-shaft has a crank-arm 0 formed with a lateral finger a such rock-shaft being held to rock in the direction indicated by the arrow in Fig. 10 by means of a torsion-spring c. The cam-shaft C, before referred to, is also journaled in the bearing 0 and has a cam 0 which engages the finger a and serves, when its concentric face engages it, to hold the plunger Q up, it being understood that when the cam portion comes in place the spring 0 will force the plunger down between arms P P 1 The fly-shaft K before referred to, is journaled in front of the upper edge of the wheel L at one end in an arm k and at its other in a bearing-block is, secured upon the bar a", and carries at such end a pinion 715 which meshes with a mutilated pinion k on the drive-shaft D before referred to. It will be noticed by reference to Fig. 6 that the bands which lead the paper to the fly-shaft and the fly-fingers are so arranged that the four-fold sheet will be carried onto the fly with its marginal edge projected over arms P In the practical construction the fly-shaft is held rocked in one (inward) direction bya spring or other equivalent device, whereby when its drive-pinion becomes disengaged from the mutilated drive-gear the fiy-fingers will be thrown inward and down to receive the folded sheet and is held down during the time the mutilated and drive gears are disengaged. At this time the plunger Q is released and is thrown down to make the imprint on the paper, after which it again rises through the medium of the cam-lifting mechanism before referred to. After the impression is made the mutilated gear engages the fly-shaft and rocks it outward to discharge the paper with the address printed thereon onto a suitable platform or to wrapping devices, if desired.

The type on the addressing-wheel is in prac tice inked by.a ribbon or with a brayer by hand before the wheel is placed on the shaft, if desired. After the paper issues from the last-fold rolls it passes upon the fly, 011 which are the three projections or stops. (Plainly shown in Fig. 1.) The instant the paper stops the printing-arm Q Fig. 10, descends upon the paper, presses the paper upon the type, and thereby prints the address.

The printing-arm is immediately lifted, and the fly piles the paper on a suitable table or box.

In Fig. 11 I have shown in adiagrammatic view an additional feed-table, which is used in connection with the construction above described when it is desired to fold a twentypage paper. In such construction a feed-table 8, arranged at right angles to the platform D, is employed, from which a full sheet (eight pages) is fed onto a carrier 8', arranged beneath the supplement-table, and which is arranged to feed the paper-sheet transversely to the main sheet. By this construction it will be seen that as the first folder-blade lowers it carries the main eight-page sheet and supplemental eight-page sheet, as also the supplement two or four page sheet.

From the foregoing description, taken in connection with the drawings, the complete operation of my improved machine will be readily understood.

It will be noticed that by arranging the first folder-blade-operating mechanism in the man ner described a very positive, effective, and simple means is provided for the purposes stated. It will also be observed that while the first and third folder-rolls are operated from the main shaft 0 the second and fourth rolls are operated from the shaft O Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
